[0030] Work flow:

[0031] I. withstand voltage detection

[0032] 1. After workpiece is placed on work station fixture, four work station turntable rotates workpiece to work station (withstand voltage detection work station) of load test module, jacking positioning piece beside turntable realizes accurate positioning;

[0033] 2. The moving contact cylinder pushes the moving contact to connect with the stationary contact on the workstation fixture;

[0034] 3. Withstand voltage tester tests the withstand voltage of the circuit.

[0035] II. Product Feature Testing

[0036] 1. The workpiece is rotated to the station at the load testing module (testing station);

[0037] 2. The moving contact cylinder pushes the moving contact to connect with the stationary contact on the workstation fixture;

[0038] 3. The clutch cylinder pushes the load clutch shaft against the load connection shaft of the workstation fixture;

[0039] 4. The servo motor rotates, and through the load shaft transmission, the load connecting shaft and the load clutch shaft are aligned. It continues to rotate past the product power-off position, and the pressure block cylinder pushes the pressure block to press the product.

[0040] Test cycle: Detects whether the product circuit is disconnected in the power-off position. If a circuit is detected, a product defect message is output; otherwise, the test continues. With the power-off stop block in the open state, the motor output torque becomes 0 Nm. The over-limit spring pulls the transmission gear, causing the power-off stop to approach the de-energized position.

[0041] On the potential range block, the PLC system detects whether the circuit is connected. If connected, it continues; otherwise, it outputs a product defect information. When the circuit is detected to be energized, the servo motor torque switches to load torque, the potential range block opens, the product is powered on, and the servo motor rotates forward. During rotation, the potential loss and potential gain blocks return to their original positions, and the product continues to rotate until it reaches the de-energized position. The system detects the process current and rotation time to ensure they are within the required range. If they are outside the range, it outputs a product defect information. From the second time onwards, the product will be driven to the de-energized position by its own motor, with all other parameters remaining unchanged. The test is performed 15 times, with 5 tests each for high voltage, low voltage, and normal voltage.

[0042] 3. After all four workstations have completed testing, the equipment stops, and the employee switches to manual mode to unload the tested products and put the untested products on the machine for testing.
