機器人畢業(yè)設計外文翻譯2-其他專業(yè)-全文預覽
【正文】 教師職稱 ： 2021 年 03月 11 日 機器人 機器人是典型的機電一體化裝置，它綜合運用了機械與精密機械、微電子與計算機、自動控制與驅(qū)動、傳感器與信息處理以及人工智能等多學科的最新研究成果，隨著經(jīng)濟的發(fā)展 和各行各業(yè)對自動化程度要求的提高，機器人技術(shù)得到了迅速發(fā)展，出現(xiàn)了各種各樣的機器人產(chǎn)品。 工業(yè)機器人是在生產(chǎn)環(huán)境中用以提高生產(chǎn)效率的工具，它能做常規(guī)乏味的裝配線工作，或能做那些對于工人來說是危險的工作，例如：第一代工業(yè)機器 人是用來在核電站中更換核燃料棒，如果人去做這項工作，將會遭受有害射線的輻射。當機器人到達位置后，它將執(zhí)行某種任務。這個基本定義引導出后續(xù)段落的其他定義，從而描繪出一個完整的機器人系統(tǒng)。因且，正是這種可編程的特征，一個工業(yè) 機器人很像一臺計算機，數(shù)據(jù)可以在這里儲存、后續(xù)調(diào)用與編輯。這些連在機器人手臂末端的附件可使機器人抬起工件、點焊、刷漆、電焊弧、鉆孔、打毛刺以及根據(jù)機器人的要求去做各種各樣的工作。 二、 機器人系統(tǒng)有三個基本 部件 ：機械手、控制器和動力源。 機械臂使機械手產(chǎn)生各軸的運動。隨著機器人機械結(jié)構(gòu)尺寸的增加，工作單元的范圍也必須相應增加。由鏈、齒輪和滾珠絲杠組成的機械傳動鏈驅(qū)動著機器人的各軸。用戶可通過手持的示教盒將機械手運動的程序編入控制器。當該加工循環(huán)完成后，輸入端接通，告訴控制器定位機械手以便能抓取以加工工件，隨后機械手抓取一未加工工件，將其放置在機床上。這些微處理器可以是 8位， 16 位或 32 位處理器。 存儲器。傳給機器人系統(tǒng)的動力源有兩種，一種是用于控制器的交流電，另一種是用于驅(qū)動機械手各軸的動力源，例如，如果機器人的機械手是由液壓和氣壓驅(qū)動的，控制信號便傳送到這些裝置中，驅(qū)動機器人運動。 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 manipulator’s 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 . illustrates the work cell of a typical assembly robot . As the robot’s 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 . The mechanical linkages may be posed of chains , gears ,and ball screws. 2. Controller The controller in the robotic system is the heart of the operation. The controller stores preprogrammed information for later recall, control peripheral devices, and municates with puters within the plant for constant updates in production The controllers is used to control the robot manipulator’s movements as well as to control peripheral ponents within the work cell. The user can program the movements of the manipulator into the controller through the use of a handheld 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 municate
