This equipment's control section utilizes Mitsubishi's latest FX5U series PLC controller, paired with Weilun touchscreen for human-machine interaction, controlling three axes for precise positioning movements. The detection section employs Keyence high-precision laser controllers and probes to measure internal length, internal width, external length, and external width of the objects, with the program automatically determining if the product meets quality standards. The laser measurement machine can move back and forth along the inner edge of a mobile phone case, using high-precision sensors to measure the distance between two points, thus determining the length and width of the mobile phone case.
