[0003] After the existing equipment is tested, there are two ways to realize the operation process of pulling out the power plug: most of the devices are manually operated, and the operator pulls out the power plug after testing; a small part of the devices are automatically operated, and the realization way is to automatically pop out the power plug. But there are the following shortcomings: 1. Great limitation: the automatic pop-out device needs to customize different tool fixtures for different standard power plugs, and different batches of products using different national standard power plugs will be produced in the production line, which has difficulty in compatibility and maintenance replacement; 2. High cost: different national standard power plugs need to be configured with multiple tool fixtures; 3. High labor intensity of operators: for devices that do not use automatic devices, other process personnel need to consider this process, which has high labor intensity of personnel, and the flow line test beat is generally 22-25 seconds per unit; 4. High safety risk: in the flow line test of the refrigerator, the popped power plug will be hung on the device, which will drag the refrigerator, causing property loss; 5. Low reliability and high failure rate: the automatic pop-out device is complex, and needs to consider the compatibility of clamping and releasing when testing the power plug, which easily causes poor contact during testing, affecting the test efficiency and test results.
