A control panel 19 and an operating switch 20 connected to the control panel 19 are arranged on the frame 1, and the operating switch 20 is connected to the dividing plate 11 and the lifting mechanism 12. The second station 5 is provided with an upper limit PIN needle 17 for testing the upper limit of the PAD height. The test end surface of the upper limit PIN needle 17 is in a high-low step shape, with the insulating area as the reference surface and the conductive area as the measuring surface.

[0025] Working principle: When used specifically, the three-station test platform 2 is synchronously tested through the rotating platform 9, namely, resistance test, PAD height upper limit and PAD height lower limit. 1. Resistance test is to determine the resistance value through resistance meter + probe measurement; 2. The upper limit of PAD height is through the upper limit PIN needle 17 with height difference, the insulating area is used as the reference surface, and the conductive area is used as the measuring surface. If the measuring surface is too high, the upper limit PIN needle 17 will be lifted up, that is, the conduction alarm will be triggered, and the product is a defective product, otherwise it is a good product; 3. The lower limit of PAD height is through the lower limit PIN needle 18 with height difference, the insulating area is used as the reference surface, and the conductive area is used as the measuring surface. If the measuring surface is too low, the lower limit PIN needle 18 cannot touch the conductive area, and the non-conduction alarm will be triggered, and the product is a defective product, otherwise it is a good product; the indexing plate 11 is used as a rotating mechanism to control the rotation of the rotating platform 9, and the indexing plate is operated through the control panel 19 and the operating switch 20. The three stations perform their respective duties and start testing at the same time to improve work efficiency.

[0026] Embodiment 1: The present invention does not limit the number of the lower positioning universal fixtures 10, and the three-station test platform 2 can be adjusted according to the positions of the lower positioning universal fixtures 10. For example, if there are 5 lower positioning universal fixtures 10, the three-station test platform 2 is distributed at the corresponding positions of the five equal parts.
