[0037] The action process of the present invention:

[0038] 1. Pin conduction and withstand voltage test. The product rotates to the second station 22, the conduction and withstand voltage lower membrane probe 321 fixed on the frame 10 does not move or moves upward, and the conduction and withstand voltage upper membrane probe 323 moves downward, and contacts the pins in the upper and lower directions of the product at the same time, respectively testing whether the upper and lower integrated pin' pins are conductive, and testing whether the adjacent pin pins are insulated, and feeding back the conduction and insulation information of the product pin pins to the PLC. The PLC knows whether the product is OK through the received information. OK products enter subsequent testing, and NG products do not undergo subsequent testing. After the rotating table 20 drives the product to rotate to the fifth station 25 under the control of the PLC, the product is dropped into the conduction and withstand voltage NG box through the servo gripper, which can be the airtightness detection material grabber 352 (the same below);

[0039] 2. Pin height detection. The product rotates to the third station 23, and the height detection depth sensor 333 fixed on the frame 10 moves forward, backward, left, right, up and down at the same time. First, find a reference point on the product to test its height. The height detection servo module 332 moves forward, backward, left, right, up and down. The height detection depth sensor 333 tests the height of each pin respectively. By comparing the tested data with the reference data, the specific height of each pin is calculated, and the product height test information is fed back to the PLC. The PLC knows whether the product is OK through the received information. OK products enter subsequent testing, and NG products do not undergo subsequent testing. After the product rotates to the fifth station 25, the servo gripper throws the product into the pin height NG box.

[0040] 3. PIN position detection. The product rotates to the fourth station 24, and the position detection camera 342 and the position detection telecentric lens 343 are moved to the position for position detection through the position detection servo module 341 to take pictures. The image is analyzed through the captured image to find the center point of the pin, and the distance to the plastic part is calculated based on the center point of the pin. The specific distance of each pin center point is calculated, and the product position test information is fed back to the PLC. The PLC knows whether the product is OK through the received information. OK products enter subsequent inspections, and NG products do not undergo subsequent inspections. After rotating to the fifth station 25, the product is dropped into the pin position NG box by the servo gripper.

[0041] 4. Air tightness test. The product rotates to the fifth station 25, and the air tightness test material grabber 352 moves the product to the lower membrane 356 of the air tightness test product. The air tightness test base drives the inlet and outlet cylinder 354 to retract, and the lower membrane 356 of the air tightness test product moves to just below the upper membrane 355 of the air tightness test product. The air tightness test pressing cylinder 353 presses down to perform an air tightness test. After the test, the air tightness test base drives the inlet and outlet cylinder 354 to extend, and the lower membrane 356 of the air tightness test product returns to its original position. The information on the air tightness of the product is fed back to the PLC. The PLC knows whether the air tightness of the product is OK through the received information. OK products enter the subsequent process, and NG products do not go through the subsequent process. The product is thrown into the air tightness test NG box through the servo gripper.
