The free end of the pressing rod 1201 is pressed down, the pressing rod 1201 presses down the top plate 9 through the pressing block 1202, and the top plate 9 and the floating plate 8 can vertically descend relative to the bottom plate 7 due to the fact that the first vertical moving mechanism 10 is arranged on the left side and the right side between the bottom plate 7 and the floating plate 8, and the second vertical moving mechanism 11 is arranged on the left side and the right side between the floating plate 8 and the top plate 9. In the process that the top plate 9 and the floating plate 8 descend, the third needle seat 901 on the top plate 9 is connected with one of the couplers 104 of the three-camera module 1 through the third through hole 301, and the first needle seat 701 and the second needle seat 702 on the bottom plate 7 are connected with the other two couplers 104 of the three-camera module 1 through the first through hole 401 and the second through hole 402 respectively, so that the three couplers 104 of the three-camera module 1 can be in signal connection with the test equipment through the three needle seats respectively, and the performance test of the test equipment on the three-camera module 1 is realized.

After the top plate 9, the floating plate 8 and the bottom plate 7 are combined, the free end of the pressure lever 1201 is locked through the locking device 1203, the pressure lever 1201 continuously presses down the top plate 9 and the floating plate 8 through the pressure block 1202, and the top plate 9, the floating plate 8 and the bottom plate 7 are ensured to be combined all the time in the performance test process.

The performance test of the three-camera module 1 is realized by the test carrier 2 and the test support 16 specially designed for the three-camera module 1. The arrangement of the first up-down vertical movement mechanism 10 and the second up-down vertical movement mechanism 11 ensures that the three needle bases of the test support 16 can be vertically connected with the three couplers 104 of the three camera shooting module 1, thereby avoiding the occurrence of displacement deviation in the connection process and causing damage to the couplers 104.

Finally, the applicant should claim that, although the present application is directed to a three-camera module, if a two-camera module, a four-camera module and an N-camera module (N is a natural number greater than 5) similar to the structure of the three-camera module are present, the applicant considers that the number of needle bases, coupler fixing grooves, light transmission holes and the like can be correspondingly increased or decreased based on the technical scheme of the present application according to the number of actual cameras, and the design modification does not require creative labor, so that the present application also belongs to the protection scope of the present application.
