Using a stepper motor as the driving source, the push rod is driven to rotate back and forth, thereby completing the reciprocating action of "opening and closing" the cabinet door. The opening and closing are controlled by PLC, simulating the action of manually opening and closing the door. By using PLC control to perform up and down door opening test actions on the product, combined with flexible and versatile fixtures, it can meet the requirements of various types of washing machine/electric oven doors, with strong universality, simple operation, convenient control, and low failure rate.
