[0060] During this process, the side of the expansion plate 704 away from the static mold plate 702 abuts against the sliding slope 711 on the dynamic mold plate 701. Under the action of the reaction force of the expansion plate 704 abutting against the sliding slope 711 on the dynamic mold plate 701, the dynamic mold plate 701 slides away from the static mold plate 702, and the tension spring 703 is stretched to increase the distance between the dynamic mold plate 701 and the static mold plate 702, so that the circuit board 1 to be detected can be placed between the dynamic mold plate 701 and the static mold plate 702.
[0061] When the adjustment of the dynamic mold plate 701 is completed, the detection personnel pull the compression column 94, and the compression column 94 drives the side pressing block 92 to compress the abutting spring 95 against the abutting plate 93. Then, the detection personnel places the circuit board 1 between the dynamic mold plate 701 and the static mold plate 702. At this time, the expansion plate 704 can support the bottom of the circuit board 1.
[0062] The detection personnel rotates the compression angle plate 91, and the rotating compression angle plate 91 limits the circuit board 1 in the placement slot 15 opened on the dynamic mold plate 701 and the static mold plate 702. Then, the detection personnel releases the compression column 94, and the abutting spring 95 restores the deformation and abuts against the side edge of the circuit board 1 through the side pressing block 92. The side pressing block 92 and the compression angle plate 91 complete the fixation and positioning of the circuit board 1, and the detection personnel plugs the plug 10 on the adjustment seat 111 into the socket 2 on the fixed circuit board 1.
[0063] Then the detection personnel pulls the handle of the push-pull type quick clamp 81, and the top pressing head of the push-pull type quick clamp 81 drives the second mounting plate 62 to approach the adjustment seat 111 until the second mounting plate 62 abuts against the upper surface of the adjustment seat 111. At this time, the detection personnel supplies power to the electromagnet 112 through the control panel 4, and the energized electromagnet 112 fixes the adjustment seat 111 and the plug 10 on the second mounting plate 62, thereby completing the accurate positioning of the plug 10.
[0064] After that, the same specification circuit board 1 is replaced. After the circuit board 1 is fixed on the lower mold plate 7 again, the detection personnel pulls the handle of the push-pull type quick clamp 81, and the top pressing head of the push-pull type quick clamp 81 drives the second mounting plate 62 to approach the circuit board 1 through the first mounting plate 61. The second mounting plate 62 drives the buffer column 64 to synchronously descend until the rubber column 66 abuts against the upper surface of the circuit board 1.
[0065] With the second mounting plate 62 continuing to descend, the buffer compression spring 67 will be compressed, the descending speed of the second mounting plate 62 will slow down, with the second mounting plate 62 continuously descending, the second mounting plate 62 will drive the plug 10 on the adjusting seat 111 to gradually plug into the socket 2 on the circuit board 1, then the detection personnel will control the control panel 4, the control panel 4 will detect the circuit board 1 through the wire connected with the plug 10, so as to quickly obtain the various performance indexes of the circuit board 1.
[0066] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
