Industrial RobotsDefinition“A robot is a reprogrammable,multifunctional machine designed to manipulate materials,parts,tools,or specialized devices,through variable programmed motions for the performance of a variety of tasks.”-Robotics Industries Association “A robot is an automatic device that performs functions normally ascribed to humans or a machine inf orm of a human.”-Websters DictionaryThe industrial robot 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 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 robots 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-arm tool , sensor , and 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 , materials , tools , 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 a complete 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 robots memory and are recalled later for continuous operation . 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 stored 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 manipulators axes , also called the degrees of freedom of the robot . A robot can have from 3 to 16 axes . The term degrees of freedom of freedom will always relate to the number of axes found on a robot .4. The tooling and grippers are not part of the robotic system itself ; rather , they are attachments that fit on the end of the robots arm . These attachments connected to the end of the robots 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 also control the work cell of the operating robot . the work cell of the robot is the total environment in which the robot must perform its task . 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 in order to tell the robot when it should assemble 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 connection of the base and the appendage of a robot .The 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 another .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 remain in one location。At the end of the arm , a wrist 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 .The manipulators axes allow it to perform work within a certain area . This area is called the work cell of the robot , and its size corresponds to the size of the manipulator . Fig.2 illustrates the work cell of a typical assembly robot . As the robots physical size increases , the size of the work cell must also increase .The movement of the manipulator is controlled by actuators , or drive systems . The actuators , or drive system , 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 drive systems .The drive systems are coupled through mechanical linkages .These linkages, in turn , drive the different axes of the robot . Themechanical linkages may be composed of chains , gears ,and ball screws.B. ControllerThe controller in the robotic system is the heart of the operation. The controller stores preprogrammed information for later recall, control peripheral devices, and communicates with computers within the plant for constant updates in productionThe controllers is used to control the robot manipulators 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 hand-held teach pendent. This information is stored in the memory of the controller for later recall. The controller stores all program data of the robotic system. It can store several different programs, 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 turns 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 controller can send electric signals over communication lines that allow it to talk with the various axes of manipulator. This two-way communication between the robot manipulator and the controller maintains a constant update of the location and the operation of the system. The controller also controls any tooling placed on the end of the robots wrist.The controller also has the job of communicating with the different plant computers . The communication link establishes the robot as part of a computer-assistedmanufacturing (CAM) system.As the basic definition stated , the robot is a reprogrammable , multifunctional manipulator . Therefore , the controller must contain some type of memory storage . The microprocessor-based systems operate in conjunction with solid-state memory devices . These memory devices may be magnetic bubbles , random-access memory , floppy disks , or magnetic tape . Each memory storage device stores program information for later recall or for editing .C. SensorsMeasure robot configuration/condition and its environment send such information to robor controller as electronic signals (e.g.,arm position,presencs of toxic gas ).D. User interfanceThis is the part for the user to operate a robot,i.e.,the control panel.E. Manipulator baseA robot may work in a fixed base,or in a mobile base,that is ,it can move about by employing wheels or legs.F. Power supplyThe power supply is the unit that supplies power to the controller and the manipulator . Two types 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 is used for driving the various axes of the manipulator . For example , if the robot manipulator id controlled by hydraulic or pneumatic manipulator 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 , These power sources are part of the total components of the robotic work cell .工業(yè)機(jī)器人定義“機(jī)器人是一種可重復(fù)編程和多功能的機(jī)器,它是用于操縱材料、部件、工具或者特殊化的裝置,通過(guò)多樣的已編程的動(dòng)作以適用于各種任務(wù)?!?機(jī)器人工業(yè)協(xié)會(huì)“機(jī)器人是一種執(zhí)行功能取決于人類或者接受人類指令的自動(dòng)機(jī)器?!?韋氏詞典

產(chǎn)品介紹,研究的意義,同類研究工作國(guó)內(nèi)外現(xiàn)狀、面臨挑戰(zhàn)(列出主要參考文獻(xiàn))工業(yè)機(jī)器人介紹:工業(yè)機(jī)器人是一種模擬人手臂、手腕和手功能的機(jī)電一體化裝置,其應(yīng)用領(lǐng)域分為很多種類,從常用的機(jī)器人系列和市場(chǎng)占有率來(lái)看,焊接、裝配、搬運(yùn)、上料/卸料、鑄造、沖壓和噴漆是主要的工業(yè)機(jī)器人品種。工業(yè)機(jī)器人產(chǎn)業(yè)鏈由零部件企業(yè)、本體企業(yè)、系統(tǒng)集成商、代理商、終端客戶構(gòu)成。當(dāng)前,工業(yè)機(jī)器人應(yīng)用領(lǐng)域正不斷拓寬,種類更加繁多,功能越來(lái)越強(qiáng),自動(dòng)化和智能化水平顯著提高。據(jù)國(guó)際機(jī)器人聯(lián)合會(huì)統(tǒng)計(jì),來(lái)自汽車整車及零部件工業(yè)的需求,合計(jì)占工業(yè)機(jī)器人下游總需求的60%左右。在亞洲,電子電氣工業(yè)對(duì)工業(yè)機(jī)器人的需求僅次于汽車工業(yè)排名第二。研究意義:1、衡量一個(gè)國(guó)家制造業(yè)水平和科技水平的重要標(biāo)志;2、重塑我國(guó)制造業(yè)競(jìng)爭(zhēng)優(yōu)勢(shì)的重要工具和手段;3、加快我國(guó)工業(yè)轉(zhuǎn)型升級(jí)的務(wù)實(shí)之選。工業(yè)機(jī)器人產(chǎn)業(yè)發(fā)展現(xiàn)狀與趨勢(shì):世界1、市場(chǎng)需求呈現(xiàn)快速增長(zhǎng)態(tài)勢(shì)受技術(shù)快速發(fā)展、勞動(dòng)力資源不斷稀缺、生產(chǎn)效率要求近一步提高等因素影響,全球工業(yè)機(jī)器人將迎來(lái)更為廣闊的發(fā)展空間和更高的發(fā)展速度。在區(qū)域分布上,隨著亞洲地區(qū)制造業(yè)的發(fā)展,各項(xiàng)產(chǎn)業(yè)對(duì)于工業(yè)機(jī)器人的需求量增加,使得工業(yè)機(jī)器人市場(chǎng)需求逐漸由歐美地區(qū)轉(zhuǎn)移到亞洲地區(qū)。2、技術(shù)日益智能化、模塊化和系統(tǒng)化從近幾年世界推出的機(jī)器人產(chǎn)品來(lái)看,新一代工業(yè)機(jī)器人正在向智能化、模塊化和系統(tǒng)化方向發(fā)展。3、西方工業(yè)化發(fā)達(dá)國(guó)家紛紛進(jìn)行戰(zhàn)略部署美國(guó):推行“再工業(yè)化”戰(zhàn)略,大力發(fā)展工業(yè)機(jī)器人,希望重振制造業(yè)。日本:日本可以稱得上是“機(jī)器人大國(guó)”。2004年5月發(fā)布的“新產(chǎn)業(yè)發(fā)展戰(zhàn)略”明確了機(jī)器人產(chǎn)業(yè)等7個(gè)產(chǎn)業(yè)領(lǐng)域?yàn)橹攸c(diǎn)發(fā)展產(chǎn)業(yè)。近兩年又開(kāi)始重新審視機(jī)器人產(chǎn)業(yè)政策。韓國(guó):2009年公布智能機(jī)器人基本計(jì)劃,2012年10月發(fā)布了“機(jī)器人未來(lái)戰(zhàn)略展望2022”,將政策焦點(diǎn)放在了擴(kuò)大韓國(guó)機(jī)器人產(chǎn)業(yè)并支持國(guó)內(nèi)機(jī)器人企業(yè)進(jìn)軍海外市場(chǎng)方面。歐盟:歐盟2011年8月通過(guò)了一份發(fā)展制造業(yè)計(jì)劃,提出新工業(yè)革命概念,以機(jī)器人和信息技術(shù)為支撐,實(shí)現(xiàn)制造模式的變革。我國(guó)1、市場(chǎng)需求快速增長(zhǎng),但嚴(yán)重依賴國(guó)外進(jìn)口我國(guó)工業(yè)機(jī)器人市場(chǎng)已呈現(xiàn)出蓬勃發(fā)展的態(tài)勢(shì)。從2010年開(kāi)始我國(guó)工業(yè)機(jī)器人需求量激增,但目前我國(guó)新增工業(yè)機(jī)器人中超過(guò)70%依賴國(guó)外進(jìn)口。2、產(chǎn)業(yè)化初步取得進(jìn)展,但程度較低近年來(lái),在需求快速擴(kuò)張及國(guó)家自主創(chuàng)新政策作用下,國(guó)內(nèi)一大批企業(yè)或自主研制或與科研院所合作,進(jìn)入工業(yè)機(jī)器人研制和生產(chǎn)行列,我國(guó)工業(yè)機(jī)器人進(jìn)入了初步產(chǎn)業(yè)化階段。一些產(chǎn)品已開(kāi)始產(chǎn)業(yè)化生產(chǎn)應(yīng)用,但由于在精度、速度等方面不如進(jìn)口的同類產(chǎn)品,因此這些產(chǎn)品產(chǎn)業(yè)化應(yīng)用程度較低,缺乏品牌認(rèn)知度,市場(chǎng)份額小。3、掌握了一些先進(jìn)技術(shù),但整體技術(shù)水平仍然較低我國(guó)目前已基本掌握了機(jī)器人操作機(jī)的設(shè)計(jì)制造技術(shù)、控制系統(tǒng)硬件和軟件設(shè)計(jì)技術(shù)、運(yùn)動(dòng)學(xué)和軌跡規(guī)劃技術(shù),生產(chǎn)了部分機(jī)器人關(guān)鍵元器件,開(kāi)發(fā)出噴漆、弧焊、電焊、裝配、搬運(yùn)等機(jī)器人。一些產(chǎn)品的技術(shù)水平已達(dá)到國(guó)際先進(jìn)水平,但在總體技術(shù)上還有很大差距,僅相當(dāng)于國(guó)外90年代中期的水平。面臨挑戰(zhàn):1、外資品牌占國(guó)內(nèi)市場(chǎng)絕對(duì)份額瑞典的abb、日本的fanuc(發(fā)那科)、日本的YASKAWA(安川電機(jī))、德國(guó)的kuka(庫(kù)卡)等知名企業(yè)產(chǎn)品在中國(guó)市場(chǎng)的占有率達(dá)到近90%,僅fanuc一家,就在我國(guó)占有23%的市場(chǎng)份額。2、關(guān)鍵核心部件受制于人3、產(chǎn)業(yè)化發(fā)展有待規(guī)范伴隨我國(guó)工業(yè)機(jī)器人需求的迅猛增長(zhǎng),實(shí)力良莠不齊的企業(yè)紛紛進(jìn)入工業(yè)機(jī)器人生產(chǎn)市場(chǎng),勢(shì)必造成質(zhì)低價(jià)廉的惡性競(jìng)爭(zhēng);雖然我國(guó)有近百家從事工業(yè)機(jī)器人研究生產(chǎn)的高校院所和企業(yè),但現(xiàn)行的體制造成研究形式上過(guò)于獨(dú)立封閉、內(nèi)容上較為分散,難以形成合力,造成重復(fù)研究與時(shí)間、經(jīng)費(fèi)的浪費(fèi);多數(shù)企業(yè)熱衷于大而全,一些關(guān)鍵部件研發(fā)生產(chǎn)的企業(yè)紛紛轉(zhuǎn)入整機(jī)的生產(chǎn),難以形成研發(fā)、生產(chǎn)、制造、銷售、集成、服務(wù)等有序、細(xì)化的產(chǎn)業(yè)鏈。因此,工業(yè)機(jī)器人的產(chǎn)業(yè)化發(fā)展有待規(guī)范。4、研發(fā)及產(chǎn)業(yè)化方面的激勵(lì)政策尚需完善盡管“十一五”及“十二五”期間,國(guó)家有多個(gè)項(xiàng)目涉及機(jī)器人領(lǐng)域,但行業(yè)仍未建立起有效的公共技術(shù)平臺(tái)以加強(qiáng)關(guān)鍵共性技術(shù)和核心功能部件的研究與突破,產(chǎn)業(yè)化進(jìn)程也難以推進(jìn),研發(fā)與產(chǎn)業(yè)化方面的激勵(lì)政策尚需細(xì)化完善。2、 研究目標(biāo)、內(nèi)容和擬解決的關(guān)鍵問(wèn)題(根據(jù)任務(wù)要求進(jìn)一步具體化)研究目標(biāo):1、減輕工人的勞動(dòng)強(qiáng)度,其最終目的是把工人從簡(jiǎn)單、重復(fù)而繁重的勞動(dòng)中解放出來(lái);2、依靠工藝過(guò)程的集約化并保證兩班、三班時(shí)設(shè)備正常工作,以提高勞動(dòng)生產(chǎn)率和產(chǎn)品質(zhì)量;3、為生產(chǎn)組織中達(dá)到進(jìn)一步質(zhì)的飛躍并向全自動(dòng)化柔性生產(chǎn)過(guò)渡創(chuàng)造條件。研究?jī)?nèi)容:1、保證工藝的柔性,要適應(yīng)生產(chǎn)條件的變化;2、在經(jīng)常變換運(yùn)輸、裝料和其他輔助裝置的情況下能使不同用途的裝備進(jìn)行對(duì)接;3、運(yùn)行中工作效率和可靠性要高;4、預(yù)先考慮到進(jìn)一步發(fā)展和完善的可能性。 擬解決的關(guān)鍵問(wèn)題:1、 提高工藝靈活性,以便更好地滿足實(shí)際使用條件 建造工藝性能遠(yuǎn)遠(yuǎn)超過(guò)實(shí)際生產(chǎn)要求的通用工業(yè)機(jī)器人。通用性一般是通過(guò)操作機(jī)結(jié)構(gòu)和控制裝置復(fù)雜化來(lái)解決,這樣就會(huì)使工業(yè)機(jī)器人價(jià)格貴。此外,機(jī)器人硬件結(jié)構(gòu)的建造不可能最佳地滿足各種應(yīng)用條件,這就導(dǎo)致出現(xiàn)大量各種型號(hào)的工業(yè)機(jī)器人。2、 簡(jiǎn)化結(jié)構(gòu)以降低制造和維護(hù)的成本 建造最大限度的滿足預(yù)定工藝要求的專用和特殊工業(yè)機(jī)器人。但在這種情況下,由于工藝任務(wù)的多樣性,就導(dǎo)致出現(xiàn)大量的工業(yè)機(jī)器人型號(hào),這又將提高其制造和維護(hù)成本。3、 特色與創(chuàng)新之處M10型專用工業(yè)機(jī)器人是用來(lái)在金屬切削機(jī)床上工作的。例如車床工段的帶數(shù)控裝置機(jī)床的裝料與卸料。這種形式的工業(yè)機(jī)器人的特點(diǎn)是保證操作機(jī)工作機(jī)構(gòu)(夾持器)在球坐標(biāo)系中運(yùn)動(dòng),以及在結(jié)構(gòu)上能直接放置在所工作的工藝裝備中。工業(yè)機(jī)器人程序控制裝置使操作機(jī)工作機(jī)構(gòu)能夠沿六個(gè)坐標(biāo)軸定位,其中兩個(gè)是四個(gè)自由度機(jī)構(gòu)所共有的。采用典型獨(dú)立結(jié)構(gòu)的模塊。構(gòu)成組合式機(jī)器人,它可以單獨(dú)使用或與其它型號(hào)機(jī)器人不用組合中使用。這種模塊式工業(yè)機(jī)器人具有很大的靈活性,同時(shí)由于其機(jī)械部分和控制裝置原件的廣泛標(biāo)準(zhǔn)化,組合模塊式工業(yè)機(jī)器人的制造和維護(hù)成本也降低。4、
