外文资料robotThe industrial robot is a tool that is used in the manufacturing environment to increase productivity. It can be used to do routine and tedious assembly line jobs,or it can perform jobs that might be hazardous to the human worker . For example ,one of the first industrial robot was used to replace the nuclear fuel rods in nuclear power plants. A human doing this job might be exposed to harmful amounts of radiation. The industrial robot can also operate on the assembly line,putting together small components,such as placing electronic components on a printed circuit board. Thus,the human worker can be relieved of the routine operation of this tedious task. Robots can also be programmed to defuse bombs,to serve the handicapped,and to perform functions in numerous applications in our society.The robot can be thought of as a machine that will move an end-of-tool ,sensor ,and/or gripper to a preprogrammed location. When the robot arrives at this location,it will perform some sort of task .This task could be welding,sealing,machine loading ,machine unloading,or a host of assembly jobs. Generally,this work can be accomplished without the involvement of a human being,except for programming and for turning the system on and off.The basic terminology of robotic systems is introduced in the following:1. A robot is a reprogrammable ,multifunctional manipulator designed to move parts,material,tool,or special devices through variable programmed motions for the performance of a variety of different task. This basic definition leads to other definitions,presented in the following paragraphs,that give acomplete picture of a robotic system.2. Preprogrammed locations are paths that the robot must follow to accomplish work,At some of these locations,the robot will stop and perform some operation ,such as assembly of parts,spray painting ,or welding .These preprogrammed locations are stored in the robot’s memory and are recalled later for continuousoperation.Furthermore,these preprogrammed locations,as well as other program data,can be changed later as the work requirements change.Thus,with regard to this programming feature,an industrial robot is very much like a computer ,where data can be stoned and later recalled and edited.3. The manipulator is the arm of the robot .It allows the robot to bend,reach,and twist.This movement is provided by the manipulator’s axes,also called the degrees of freedom of the robot .A robot can have from 3 to 16 axes.The term degrees of freedom will always relate to the number of axes found on a robot.4. The tooling and frippers are not part the robotic system itself;rather,they are attachments that fit on the end of the robot’s arm. These attachments connected to the end of the robot’s arm allow the robot to lift parts,spot-weld ,paint,arc-weld,drill,deburr,and do a variety of tasks,depending on what is required of the robot.5. The robotic system can control the work cell of the operating robot.The work cell of the robot is the total environment in which the robot must perform itstask.Included within this cell may be the controller ,the robot manipulator ,a work table ,safety features,or a conveyor.All the equipment that is required in order for the robot to do its job is included in the work cell .In addition,signals from outside devices can communicate with the robot to tell the robot when it should parts,pick up parts,or unload parts to a conveyor.The robotic system has three basic components: the manipulator,the controller,and the power source.A.ManipulatorThe manipulator ,which does the physical work of the robotic system,consists of two sections:the mechanical section and the attached appendage.The manipulator also has a base to which the appendages are attached.Fig.1 illustrates the connectionof the base and the appendage of a robot.图1.Basic components of a robot’s manipulatorThe base of the manipulator is usually fixed to the floor of the work area. Sometimes,though,the base may be movable. In this case,the base is attached to either a rail or a track,allowing the manipulator to be moved from one location to anther.As mentioned previously ,the appendage extends from the base of the robot. The appendage is the arm of the robot. It can be either a straight ,movable arm or a jointed arm. The jointed arm is also known as an articulated arm.The appendages of the robot manipulator give the manipulator its various axes of motion. These axes are attached to a fixed base ,which,in turn,is secured to a mounting. This mounting ensures that the manipulator will in one location.At the end of the arm ,a wrist(see Fig 2)is connected. The wrist is made up of additional axes and a wrist flange. The wrist flange allows the robot user to connect different tooling to the wrist for different jobs.图2.Elements of a work cell from the topThe manipulator’s axes allow it to perform work within a certain area. The area is called the work cell of the robot ,and its size corresponds to the size of the manipulator.(Fid2)illustrates the work cell of a typical assembly ro bot.As the robot’s physical size increases,the size of the work cell must also increase.The movement of the manipulator is controlled by actuator,or drive systems.The actuator,or drive systems,allows the various axes to move within the work cell. The drive system can use electric,hydraulic,or pneumatic power.The energy developed by the drive system is converted to mechanical power by various mechanical power systems.The drive systems are coupled through mechanical linkages.These linkages,in turn,drive the different axes of the robot.The mechanical linkages may be composed of chain,gear,and ball screws.B.ControllerThe controller in the robotic system is the heart of the operation .The controller stores preprogrammed information for later recall,controls peripheral devices,and communicates with computers within the plant for constant updates in production.The controller is used to control the robot manipulator’s movements as well as to control peripheral components within the work cell. The user can program the movements of the manipulator into the controller through the use of a hard-held teach pendant.This information is stored in the memory of the controller for later recall.The controller stores all program data for the robotic system.It can store several differentprograms,and any of these programs can be edited.The controller is also required to communicate with peripheral equipment within the work cell. For example,the controller has an input line that identifies when a machining operation is completed.When the machine cycle is completed,the input line turn on telling the controller to position the manipulator so that it can pick up the finished part.Then ,a new part is picked up by the manipulator and placed into the machine.Next,the controller signals the machine to start operation.The controller can be made from mechanically operated drums that step through a sequence of events.This type of controller operates with a very simple robotic system.The controllers found on the majority of robotic systems are more complex devices and represent state-of-the-art eletronoics.That is,they are microprocessor-operated.these microprocessors are either 8-bit,16-bit,or 32-bit processors.this power allows the controller to be very flexible in its operation.The controller can send electric signals over communication lines that allow it to talk with the various axes of the manipulator. This two-way communication between the robot manipulator and the controller maintains a constant update of the end the operation of the system.The controller also controls any tooling placed on the end of the robot’s wrist.The controller also has the job of communicating with the different plant computers. The communication link establishes the robot as part a computer-assisted manufacturing (CAM)system.As the basic definition stated,the robot is a reprogrammable,multifunctional manipulator.Therefore,the controller must contain some of memory stage. The microprocessor-based systems operates in conjunction with solid-state devices.These memory devices may be magnetic bubbles,random-access memory,floppy disks,or magnetic tape.Each memory storage device stores program information fir or for editing.C.power supplyThe power supply is the unit that supplies power to the controller and the manipulator. The type of power are delivered to the robotic system. One type of power is the AC power for operation of the controller. The other type of power isused for driving the various axes of the manipulator. For example,if the robot manipulator is controlled by hydraulic or pneumatic drives,control signals are sent to these devices causing motion of the robot.For each robotic system,power is required to operate the manipulator .This power can be developed from either a hydraulic power source,a pneumatic power source,or an electric power source.There power sources are part of the total components of the robotic work cell.中文翻译机器人工业机器人是在生产环境中用以提高生产效率的工具,它能做常规乏味的装配线工作,或能做那些对于工人来说是危险的工作,例如,第一代工业机器人是用来在核电站中更换核燃料棒,如果人去做这项工作,将会遭受有害放射线的辐射。
Robots机器人 中英文翻译

RobotsA robot is an automatically controlled, reprogrammable, multipurpose, mani pulating machine with several reprogrammable axes, which may be either fixed in place or mobile for use in industrial automation applications.The key words are reprogrammable and multipurpose because most single-purpose machines do not meet these two requirements.The term”reprogrammabl e” implies two things:The robot operates according to a written program can b e rewritten to accomdate a variety of manufacturing tasks. The term “multipurp ose” means that the robot can perform many different functions, depending on the program and tooling currently in use.Over the past two decades,the robot has been introduced into industry to perform many monotonous and often unsafe operations. Because robots can per form certain basic tasks more quickly and accurately than humans, they are bei ng increasingly used in various manufacturing industries.Structures of RobotsThe typical structure of industrial robots consists of 4 major components: the manipulator, the end effector, the power supply and control syterm.The manipulator is a mechanical unite that provides motions similar to those of a human arm. It often has a shoulder joint,an elbow and a wrist. It can rotate or slide, strech out and withdraw in every possible direction with certain flexibility.The basic mechanical configurations of the robot manipulator are categorized as Cartesian, cylindrical, spherical and articulated.A robot with a Cartesian geometry can move its gripper to any position within the cube or rectangle defined as its working volum.Cylindrical coordinate robots can move the gripper within a volum that is described by a cylinder. The cylindrical coordinate robot is positioned in the work area by two linear movements in the X and Y directions and one angular rotation about the Z axis.Spherical arm geometry robots have an irregular work envelop. This type of robot has two main variants,vertically articulated and horizontally articulated.The end effector attaches itself to the end of the robot wrist, also called end-of-arm tooling.It is the device intended for performing the designed operations as a human hand can.End effectors are generally custom-made to meet special handling requirements. Mechanical grippers are the most commonly used and are equipped with two or more fingers.The selection of an appropriate end effector for a special application depends on such factors as the payload, enviyonment,reliability,and cost.The power supply is the actuator for moving the robot arm, controlling the joints and operating the end effector. The basic type of power sources include electrical,pneumatic, and hydraulic. Each source of energy and each type of motor has its own characteristics, advantages and limitations. An ac-powered motor or dc-powered motor may be used depending on the system design and applications. These motors convert electrical energy into mechanical energy to power the robot.Most new robots use electrical power supply. Pneumatic actuators have been used for high speed. Nonservo robots and are often used for powering tooling such as grippers. Hydraulic actuators have been used for heavier lift systems, typically where accuracy was not also requied.The contro system is the communications and information-processing system that gives commands for the movements of the robot. It is the brain of the robot; it sends signals to the power source to move the robot arm to a specific position and to the end effector.It is also the nerves of the robot; it is reprogrammable to send out sequences of instructions for all movements and actions to be taken by the robot.A open-loop controller is the simplest for of the control system, which controls the robot only by foolowing the predetermined step-by-step instructions.This system dose not have a self-correcting capability.A close-loop control system use feedback sensors to produce signals that reflct the current states of the controed objects. By comparing those feedback signals with the values set by the programmer, the close-loop controller can conduct the robot to move to the precise position and assume the desired attitude, and the end effector can perform with very high accuracy as the close-loop control system can minimize the discrepancy between the controlled object and the predetermined references.Classification of RobotIndustrial robots vary widely in size,shape, number of axes,degrees of freedom, and design configuration. Each factor influence the dimensions of the robot’s working envelop or the volume of space within which it can move and perform its designated task. A broader classification of robots can been described as below.Fixed-and Variable-Sequence Robots. The fixed-sequence robot (also called a pick-and place robot) is programmed for a specific sequence of operations. Its movements are form point to point, and the cycle is repeated continuously.The variable-sequence robot can be programmed for a specific sequence of operations but can be programmed to perform another sequence of operation.Playback Robot. An operator leads or walks the playback robot and its end effector through the desired path. The robot memorizes and records the path and sequence of motions and can repeat them continually without any further action or guidance by the operator.Numerically Controlled Robot. The numerically controlled robot is programmed and operated much like a numerically controlled machine. The robot is servocontrolled by digital data, and its sequence of movements can be changed with relative ease.Intelligent Robot. The intelligent robot is capable of performing some of the functions and tasks carried out by huanbeings.It is equipped with a variety of sensors with visual and tactile capabilities.Robot ApplicationsThe robot is a very special type of productin tool; as a result, the applications in which robots are used are quite broad. These applications can be grouped into three categories: material processing, material handling and assembly.In material processing, robots use tools to process the raw material. For example, the robot tools could include a drill and the robot would be able to perfor drilling operaytions on raw material.Material handling consists of the loading, unloading, and transferring of workpieces in manufacturing facilities. These operations can be performed relatively and repeatedly with robots, thereby improving quality and scrap losses.Assembly is another large application area for using robotics. An automatic assembly system can incorporate automatic testing, robot automation and mechanical handling for reducing labor costs, increasing output and eliminating manual handling concers.机器人机器人是一种自动控制的、可重复编程的、多功能的、由几个可重复编程的坐标系来操纵机器的装置,它可以被固定在某地,还可以是移动的以在工业自动化工厂中使用。

机器人外文翻译(中英文翻译)机器人外文翻译(中英文翻译)With the rapid development of technology, the use of robots has become increasingly prevalent in various industries. Robots are now commonly employed to perform tasks that are dangerous, repetitive, or require a high level of precision. However, in order for robots to effectively communicate with humans and fulfill their intended functions, accurate translation between different languages is crucial. In this article, we will explore the importance of machine translation in enabling robots to perform translation tasks, as well as discuss current advancements and challenges in this field.1. IntroductionMachine translation refers to the use of computer algorithms to automatically translate text or speech from one language to another. The ultimate goal of machine translation is to produce translations that are as accurate and natural as those generated by human translators. In the context of robots, machine translation plays a vital role in allowing them to understand and respond to human commands, as well as facilitating communication between robots of different origins.2. Advancements in Machine TranslationThe field of machine translation has experienced significant advancements in recent years, thanks to breakthroughs in artificial intelligence and deep learning. These advancements have led to the development of neural machine translation (NMT) systems, which have greatly improved translation quality. NMT models operate by analyzinglarge amounts of bilingual data, allowing them to learn the syntactic and semantic structures of different languages. As a result, NMT systems are capable of providing more accurate translations compared to traditional rule-based or statistical machine translation approaches.3. Challenges in Machine Translation for RobotsAlthough the advancements in machine translation have greatly improved translation quality, there are still challenges that need to be addressed when applying machine translation to robots. One prominent challenge is the variability of language use, including slang, idioms, and cultural references. These nuances can pose difficulties for machine translation systems, as they often require a deep understanding of the context and cultural background. Researchers are currently working on developing techniques to enhance the ability of machine translation systems to handle such linguistic variations.Another challenge is the real-time requirement of translation in a robotic setting. Robots often need to process and translate information on the fly, and any delay in translation can affect the overall performance and efficiency of the robot. Optimizing translation speed without sacrificing translation quality is an ongoing challenge for researchers in the field.4. Applications of Robot TranslationThe ability for robots to translate languages opens up a wide range of applications in various industries. One application is in the field of customer service, where robots can assist customers in multiple languages, providing support and information. Another application is in healthcare settings, where robots can act as interpreters between healthcare professionals and patientswho may speak different languages. Moreover, in international business and diplomacy, robots equipped with translation capabilities can bridge language barriers and facilitate effective communication between parties.5. ConclusionIn conclusion, machine translation plays a crucial role in enabling robots to effectively communicate with humans and fulfill their intended functions. The advancements in neural machine translation have greatly improved translation quality, but challenges such as language variability and real-time translation requirements still exist. With continuous research and innovation, the future of machine translation for robots holds great potential in various industries, revolutionizing the way we communicate and interact with technology.。

关键词:晶片传送机器人末端执行器、超细纤维数组、晶片1.介绍作为一个主要集成电路设备的制造行业,晶片机器人承担了精确定位,快速和稳定的传输晶片的任务。
随着集成电路产业的快速发展(比如晶圆的直径增加到300毫米), 机械制造技术的更高的要求是为了提高生产力,因此,更高的晶片传送效率是必要的。
同时,由于晶片变得越来越薄,因此晶片机器人的设计也要防止转移严重变形晶片。
末端执行器是晶圆转移机器人一个重要的组件,它有一个很大的影响传输效率机器人的硅片变形。
目前关于末端执行器的晶片传送机器人的研究很少。
因此,它是非常必要的相关研究。
发展至今有两种晶片传送机器人:真空晶片传送机器人和大气晶片传送机器人。
真空晶片传送机器人工作在真空环境而大气晶片传送机器人工作在大气环境。
对于真空晶片传送机器人,过境晶片依赖摩擦力晶片和晶圆自己的重量的末端执行器之间生成的。
虽然大气晶片传送机器人是使用真空泵在晶片和机器人的末端执行器之间产生真空。
在大气压力和真空中有一种压力区别,这造成了相当大的正常压力,然后生成足够的摩擦力来维持晶圆在机器人的位置。

因此,我们需要分析对晶片的变形产生影响各种因素。
考虑到高转换效率的要求,我们还应该建立最大转移加速和晶片传送机器人的末端执行器工作在大气环境的参数之间的关系。
(1)我们采用有限元分析方法分析吸收毛孔对晶片的变形数量的影响对于晶片的变形下产生不同数量的吸收毛孔。

所以我们需要分析半径之间的关系的吸附孔,晶片变形。
结果显示在图5和表2。
图6显示晶片变形显着增加随着规模的毛孔吸收更大。
图5 不同的吸收孔隙半径的晶片变形的曲线表2 受到不同的半径吸收毛孔作用的最大的晶片变形接触宽度在晶片的变形接触宽度末端执行器之间的影响,晶片也会影响晶片应力和变形。
我们分析了晶片变形在不同接触宽度和结果如下所示(图6)。
结果表明,晶片变形和应力作为接触宽度的增加和减少的趋势线图7中所示。
当接触宽度是20毫米,晶片最大变形是约1微米,它是可接受的。
图6 不同接触宽度的晶片变形模拟图图7 不同接触宽度的最大变形和应力曲线(4)在吸收区域压力分布我们应该研究压力在吸收地区分布以防在晶圆上存在应力集中。
如图3所示(b),当晶片是作用下吸收力F,它相当于,晶片接触一个球是在推动,力F。
根据赫兹(1882)理论,当一个理想的球体接触一个平面,真正的接触面积可以拿到如下:F -吸收力;Rs -半径的球体,这里我们假定它等于半径的吸收毛孔;Rk . -半径的实际的接触面积,E,n -弹性模量和泊松晶圆片的比例;Es,vs -弹性模量和泊松比的球体,这里我们假设它们是材料相当的末端执行器。
如果某个地点之间的距离和中心的接触面积是r,然后上的压力这个特定的点是:总体压力接触面积是:对于典型的晶片和机器人工作在大气环境、材料参数是已知的。
Vs= ,Es = 68GPa,V=,E=的平均绩点。
我们把压力分布函数的接触面积显示在方程:图8显示,没有显着变化的压力值作为X1,X2的变化,这意味着压力是近均匀分布在整个吸收面积。
因此没有应力集中在吸收区域。
图8 吸收面积压力分布图3.设计对于真空晶片传送机器基于以上研究设计一种微阵列的肿块,我们尝试设计一种用于晶片传送微阵列凹凸。
为了降低晶片变形,我们选择四个肿块联系方式并且四个肿块是完全相同的。
从方便处理方面考虑,光刻胶苏8材料被用来制造了超细纤维数组并且采用光刻技术。
原理和实际图的微阵列肿块如图12所示。
超细纤维数组是均匀分布的面具,总面积5X5毫米。
这个面具是固定的上表面一个玻璃基片面积6X6毫米,厚度3毫米。
超细纤维数组、面具、玻璃衬底,三层组成的微阵列肿块。
材料参数和尺寸参数数组和薄片是超细纤维显示在表3。
表3 超细纤维数组和晶片材料参数和尺寸参数通过SEM照片我们可以看出,纤维的表面大约是一个圆形平面,所以真正的接触面积在防颤晶片和一个单纤维之间,面积接近πr2。
基于表V,这些已知值替换得到方程:当机器人采用这类超细纤维时最大传输加速度a= m /s2。
以直径300毫米并且厚度775毫米的晶圆的典型的转移为例。
晶圆片的重量公斤。
通过方程,当机器人采用这种超细纤维肿块时我们可以得到最大附着力是Fad= 。
它可以看到最大的附着力晶片和末端执行器之间太小,阻碍了释放晶片。
物理设计的末端执行器在集成电路产业晶片盒的半标准大小的规定为300毫米晶圆。
端效应的大小应该匹配晶圆框的大小,以正确工作。
因此,有一个请求端效应的大小是长度不超过450毫米,宽度不超过250毫米,厚度没有更多的超过5毫米。
基于请求,我们最后决定我们的结束效应是390毫米长,220毫米宽,4毫米厚度。
我们也优化了末端执行器的结构结合现有的样品,并想出了一个特殊的结构实现连接的凸起和微阵列末端执行器。
最后形成的末端执行器显示在图13。
末端执行器的振动将会导致严重的问题晶片传送。
这将导致末端执行器之间的摩擦和晶片盒、甚至碰撞,这将损害晶片。
也严重的振动将导致晶片脱离末端执行器并导致严重后果。
所以共振的结束效应器和机器人臂必须避免。
通过有限元素分析的末端执行器设计在本文,我们得到它的动态特性,如下所示表4。
表4 末端执行器设计的普通频率我们已经知道通过实验(不包括在这纸),机器人臂的振动频率是23赫兹,虽然第一阶固有频率的末端执行器是72赫兹,远远超过臂的振动频率。
输入的频率也低于1赫兹。
所以最后的效应器设计是本文能够避免共振与机器人的手臂,满足请求的动态特征。
对于大气晶片传送机器人在前面研究结果的基础上,我们设计四个吸收毛孔最后效应是一致的分布在一个圆半径为110毫米。
当前大气晶片传送机器人可以达到最大的传输加速度为1 g。
这里我们把目标的末端执行器的加速度设计在达到一个加速度的 g。
然后通过方程根据已知参数,半径吸收毛孔r可以计算为r=3毫米。
根据尺寸要求末端执行器和引用对现有产品,我们终于设计末端执行器的大气晶片传送机器人如图9所示。
它的接触宽度与晶片是20毫米。
图9 (a)大气晶片传送机器人末端执行器的前面原理图;(b)背面;(c)实物在案例的共振的末端执行器和机器人手臂,我们还必须分析末端执行器的动态特征。
他们见表5,从这可以看到,第一阶固有频率的结束效应是54302赫兹,比手臂的振动频率是23赫兹。
同样的频率输入低于1赫兹。
所以设计的末端执行器能够为了避免共振与机器人的手臂,来满足要求动态特性。
表5 大气机器人末端执行器的普通频率4.结论对于真空晶片传送机器人的末端执行器。
首先,本文应用研究壁虎启发超细纤维阵列的设计末端执行器的真空晶片传输机器人。
晶圆片的变形与不同的联系在真空条件转移比较它显示4个凹凸接触是最合适的方法。
超细纤维的研究数组用于晶片交通运输和关系在晶片传送加速度、附着力和材料、尺寸参数的超细纤维数组建立了。
然后一种微阵列凹凸与纤维直径5毫米和纤维长度15毫米的设计和固定到一个结构优化的末端执行器。
最后,实验结果表明,该机器人采用这种微阵列可以实现传输加速度撞s2,远远大于传统疙瘩由不锈钢吗钢或橡胶。
这意味着应用程序的超细纤维数组对真空转移机器人具有显着提高机器人的传输效率和这个有着重要的意义来集成电路制造行业。
还s2基本上是符合理论价值s2和它验证这项研究的正确性的超细纤维数组用于晶片过境。
对于末端执行器大气晶片传送机器人,我们已经分析了吸收毛孔的号码, 位置,半径和接触宽度在晶片变形影响。
据分析,四个吸收毛孔一致分布在一个圆半径为110 mm被选择作为我们的设计方案。
压力分布在吸收面积研究和结果显示没有压力集中在这个地区。
