經(jīng)測試，新品chainflex高柔性電纜的扭轉(zhuǎn)角度達(dá)360°，可將數(shù)據(jù)安全傳輸給6軸機(jī)器人 在大規(guī)模的制造業(yè)中，工業(yè)機(jī)器人無處不在。它們實現(xiàn)了快速自動化生產(chǎn)，從而確保了企業(yè)的成本效益。igus現(xiàn)在研發(fā)出一款新型的耐用以太網(wǎng)電纜CFROBOT8.PLUS，以確保機(jī)器人各軸、控制系統(tǒng)和上級系統(tǒng)之間的通信即使在極端壓力下也能安全傳輸。新電纜系列已經(jīng)在igus測試實驗室中經(jīng)過多年的扭轉(zhuǎn)測試，在超過1500萬次的循環(huán)運(yùn)行中未發(fā)生任何故障。 機(jī)器人在制造業(yè)中的應(yīng)用數(shù)量正在急劇增長。國際機(jī)器人聯(lián)合會（IFR）預(yù)計：到2020年，全球?qū)⒂?00多萬臺工業(yè)機(jī)器人投入使用，這將大大推動制造業(yè)的自動化進(jìn)程。與此同時，對機(jī)器人各軸、控制系統(tǒng)和上級系統(tǒng)之間安全通信的要求也在不斷提高。德國igus公司的chainflex高柔性電纜部門經(jīng)理Rainer R?ssel表示：“工業(yè)以太網(wǎng)主導(dǎo)未來通信的可能性非常高。” 為此，運(yùn)動電纜專家igus花了五年多的時間研發(fā)以太網(wǎng)電纜，以實現(xiàn)機(jī)器人部件之間的安全數(shù)據(jù)傳輸。在2018年的德國紐倫堡工業(yè)自動化及元器件展（SPS IPC Drives）上，igus向?qū)I(yè)觀眾展示了CFROBOT8.PLUS電纜系列。R?ssel表示：“這款新型機(jī)器人電纜的扭轉(zhuǎn)角度可達(dá)+/- 360°，填補(bǔ)了市場空白。igus也因此成為了一家現(xiàn)貨供應(yīng)耐用且經(jīng)測試的扭轉(zhuǎn)電纜的制造商。” 經(jīng)測試且提供質(zhì)保的扭轉(zhuǎn)電纜 在占地2,750㎡的igus測試實驗室內(nèi)，CFROBOT8.PLUS被安裝在igus的triflex三維拖鏈系列中，接受扭轉(zhuǎn)測試，目前循環(huán)次數(shù)已超過1500萬次。測試結(jié)果顯示，電纜的以太網(wǎng)通信特性完好無損。為了確定這款電纜的預(yù)期***長使用壽命，這一電纜系列的測試仍在持續(xù)進(jìn)行中。預(yù)計可能要到數(shù)年后才會得到***終的測試結(jié)果。igus在這個業(yè)內(nèi)大的實驗室中研發(fā)和測試電纜的歷史已經(jīng)超過30年，這些電纜都是專門為拖鏈應(yīng)用而設(shè)計的。憑借每年超過20億次的循環(huán)測試和超過140萬次的電氣測量，igus的高柔性電纜被公認(rèn)為是拖鏈專用運(yùn)動電纜。德國igus公司也是一家為其包括新款CFROBOT8.PLUS在內(nèi)的全部chainflex高柔性電纜系列提供36個月質(zhì)保的制造商。
高柔性以太網(wǎng)電纜CFROBOT8.PLUS系列，可以在扭轉(zhuǎn)角度360°的條件下完成1500萬次循環(huán)運(yùn)動，并快速傳輸數(shù)據(jù)到6軸機(jī)器人。（來源：igus GmbH）
