、復(fù)位進退氣缸、升降氣缸、夾手或真空吸盤、物料塊、傳感器、圓柱導(dǎo)軌、支架、底座、微動開關(guān)等組成。夾手或真空吸盤可以夾住或吸住物料塊，抓取物料的部分采用夾持式和吸附式兩種形式，選用不同的形式，可分別完成工件的抓取和吸附，以適應(yīng)不同種類的物料搬運。夾手采用電磁鐵吸合與斷開方式夾持物料。夾手或吸盤在升降氣缸的作用下可以上下移動；夾手或真空吸盤連同升降氣缸在左右移動氣缸的作用下沿著圓柱導(dǎo)軌可以左右移動；在復(fù)位進退氣缸的作用下將物料塊送回原始位置，為下一個工作周期準備，以實現(xiàn)循環(huán)。此系統(tǒng)能夠?qū)崿F(xiàn)物料在一個平面內(nèi)的搬運。操作面板安裝在電控箱上，與實驗裝置主體是分離的。PLC可編程序控制器，電磁閥，真空發(fā)生器等均放置在電

automatically under the PLC control many kinds of moreover, the material is clamped the hand transporting pletes, for satisfies continuously acts the need, but also must ship this material the zero point position, will supply the next time to transport the system may plete each working is as foot: May realize the rise, the drop, the left shift, the right lateral, the clamp, the relaxation, pushes the material to enter, to push the material to draw back and so on eight kind of spots to move the operation。Continuously: After presses down “the start” the button, clamps the hand to start from the zero point position continuously to carry out the transporting transporting system realization movement: The drop stresses the material rise right lateral to drop the loose material to rise again the left shift to push the material again to enter pushes the material to draw this system, we only realize a material cyclic action, therefore returns to the zero point after the manipulator, must drive back the homing position the realize the single acting under the PLC control, act continuously the after the system the electricity, according to turns the choice through revolving is the single acting or the gearing, if is the single acting carries out the single acting procedure, otherwise carries out the gearing acting working: To clamps hand each movement using the button alone to carry on the : Presses down the start button, clamps the hand to start from the zero point, according to the working procedure autocycle work, until presses down the pause button, clamps the hand after to plete last cyclical the work, returns to the zero point, 、上下移動及對物料的夾緊和放松、推料進退功能，在PLC控制下可實現(xiàn)單步、自動等多種工作方式。另外，物料被夾手搬運完成以后，為滿足連續(xù)動作需要，還必須將此物料運送回原點位置，以供下次搬運需要。系統(tǒng)可完成的各種工作方式如下。單步：可實現(xiàn)上升、下降、左移、右移、夾緊、放松、推料進、推料退等八種點動操作；連續(xù)：按下“啟動”按鈕后，夾手從原點位置開始連續(xù)不斷地執(zhí)行搬運物料。物料搬運系統(tǒng)實現(xiàn)的動作：下降 8外文翻譯資料→抓料→上升→右移→再下降→松料→再上升→左移→推料進→推料退。在這個系統(tǒng)中，我們只實現(xiàn)一個物料的循環(huán)動作，故在機械手回原點后，需將物料推回原來位置。在PLC控制下可實現(xiàn)單動、連續(xù)動作工作方式。系統(tǒng)上電后，通過旋轉(zhuǎn)按扭選擇是單動還是連動，如果是單動則執(zhí)行單動程序，否則執(zhí)行連動程序。單動工作方式：利用按鈕對夾手每一動作單獨進行控制。連續(xù)：按下啟動按鈕，夾手從原點開始，按工序自動循環(huán)工作，直到按下停止按鈕，夾手在完成最后一個周期的工作后，返回原點，自動停機Can realize the material autocycle transporting based on the PLC control material transporting system both may use clamps the hand clamp material, and may use the vacuum cup adsorption material, has the multiple functions function。The pneumatic system electromagnetism cross valve uses the afflux board containerization, reduced has taken the space。May realize the single acting and the gearing two execution way under the PLC control, pletes the material the 。此系統(tǒng)既可以使用夾手夾持物料，又可以使用真空吸盤吸附物料，具有多種用途功能；氣動系統(tǒng)的電磁換向閥采用匯流板集裝，減少了占用空間；在PLC的控制下可以實現(xiàn)單動和連動兩種執(zhí)行方式，完成物料的搬運。Regarding small and
