To reduce the risk of error in an assembly operation, a one-piece EZ-LIGHT PVD pick-to-light sensor with a 400 mm range is interfaced with a process controller programmed with the correct assembly sequence. The controller makes the PVDs light up in the correct order, to show the assembler which part to pick.
After the PVD detects that the assembler's hand has entered and left the bin, the controller signals the PVD of the next bin in the pick sequence to light up.
此解決方案需要光幕感测器緊密地安裝在機器開口處,且端點到端點之間的感測沒有盲區。將光幕安裝在距離機器危險區域盡可能接近的位置,可以盡可能的縮小體積(這減小了操作員的觸及距離),消除了障礙以及美觀問題。Banner的EZ-SCREEN LP安全光幕佔地面積為28 mm x 26 mm(1.1" x 1"),一體式的設計,可以安裝在狹小的空間內。
