[0037] The working principle of the present invention is as follows: the jig 200 flows from the conveyor line 100 to the top of the jacking test module 2, and the proximity sensor senses the position of the jig 200 and feeds back the information to the blocking cylinder 214, the blocking cylinder 214 is driven, the blocking plate 215 is raised, and the jig 200 cannot continue to move under the blocking of the blocking plate 215; the two jacking cylinders 213 act synchronously to lift the jacking carrier plate 211, and the two coarse positioning pins 212 on the jacking carrier plate 211 are inserted into the two coarse positioning bushings 201 of the jig 200, and then the jacking carrier plate 2 11 Continue to move upward so that the fixture 200 is separated from the conveyor line 100 and the upper end surface of the fixture 200 is against the lower ends of the two rows of follower bearings 37. At this time, the fixture 200 is clamped and fixed under the action of the lifting assembly and the follower bearings 37; the first batch of product testing begins, the downward pressure cylinder 32 drives the upper needle block 33 to move downward, and the upper needle block 33 is fitted on the upper end surface of the fixture 200 through the two upper precision positioning pins 35 and the two precision positioning bushings 202. The upper Kevin probe 36 contacts the pad point at the upper end of the first batch of tested products, and the lifting screw motor 22 3 drives the lower needle block 221 to move upward, and the upper needle block 33 is fitted on the lower end surface of the fixture 200 through the engagement of the two lower precision positioning pins 222 and the two precision positioning bushings 202, and the lower Kevin probe 224 contacts the pad point at the lower end of the first batch of tested products, thereby achieving conduction and completing the test. After the test of the first batch of products is completed, the upper needle block 33 and the lower needle block 221 are reset; then the driving motor 25 drives, and the moving plate 24 moves the set distance along the conveying direction of the conveyor line 100. At this time, the fixture 200 is synchronously moved under the drive of the lifting carrier plate 211. Due to the functional characteristics of the follower bearing 37, the fixture 200 can move smoothly, and then the second batch of product testing begins, and the action steps are consistent with the first batch of product testing; the third and fourth batches of product testing are carried out according to the above steps; after the fourth batch of product testing is completed, the upper needle block 33 and the lower needle block 221 are reset, the lifting plate 211 is reset, the fixture 200 returns to the conveyor line 100, the blocking cylinder 214 is retracted, the fixture 200 is taken away by the conveyor line 100, and the moving plate 24 is reset at the same time, preparing for the test of the next fixture 200 product.

[0038] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
