The clamping assembly 284 includes a fixed block fixed on the upper surface of the first support frame 282, a moving block elastically connected to the fixed block by a spring, a roller rotatably arranged at the end of the moving block and capable of moving on the guide surface, and a support plate fixed above the moving block and driving the movable clamping block 272 to open.

[0043] The probe card assembly 292 includes a PCBA board 2921 and a probe card fixed on the upper surface of the PCBA board 2921 and in contact with the Pad of the material. The PCBA board 2921 is connected to an external test circuit to serve as an electrical connection; the probe card is mounted on the Pad of the material to be tested, so that the signal is transferred through the probe card via the PCBA board 2921 to the external test circuit for signal processing to achieve relevant tests.

[0044] The position adjustment component 293 is configured as a UVW alignment platform, and the first camera 296 is disposed below the position adjustment component 293.

[0045] In this embodiment, each of the loading and unloading station 21, the first test station 22, the second test station 23 and the third test station 24 is provided with six carriers. Although six carriers 27 are provided, the test mechanism 29 occupies a certain volume, and six test mechanisms 29 cannot be installed under each station. Therefore, in this embodiment, two test mechanisms 29 are installed under the carrier 27 of each test station, and the three test stations perform the same test at the same time. The material dislocation test at each station can test six materials at the same time. The first test station 22 tests the materials in the No. 1 and No. 4 carriers 27, the second test station 23 tests the materials in the No. 2 and No. 5 carriers 27, and the third test station 24 tests the materials in the No. 3 and No. 6 carriers 27.

The material that has scanned OK enters the testing process, and the material that has scanned NG is released by the grabbing component 67 and flows out and is collected along the defective product conveyor line (not shown in the figure).

[0051] In this embodiment, six materials are grabbed each time, and two cameras are set up, that is, 2 pieces of materials are scanned each time. After each material is grabbed, the loading and grabbing device 5 moves forward three times to complete the scanning. In other embodiments, the number of cameras can be set according to actual conditions.

[0052] The feeding device 3 includes two linear guide rails 31 arranged in parallel and a conveying drive mechanism 32 arranged on the inner side of the linear guide rails and used to drive the material tray 200 to flow.

[0054] The loading assembly 33 includes two transverse inserting plates 331 disposed above the linear guide rail 31, a twelfth driving member 332 driving the transverse inserting plates 331 to move up and down, and a thirteenth driving member 333 driving the transverse inserting plates 331 to move laterally to support or move away from the material tray 200. Under the action of the twelfth driving member 332 and the thirteenth driving member 333, the transverse inserting plates 331 can support the material trays 200 above the second to last layer without falling.

[0055] The material unloading assembly 35 includes a connection seat 351 fixed on the linear guide rail 31 and a swing support block 352 rotatably arranged on the connection seat 351 and used to hold the material tray 200. An elastic component is also arranged between the swing support block 352 and the connection seat 351 to reset the swing support block 352. The material tray 200 moves to the bottom of the unloading assembly 35, and the bearing plate 326 drives the material tray 200 to rise so that the swing support block 351 can be squeezed and rotated to give way. Since the width of the bearing plate 326 is smaller than the width of the material tray 200, after the material tray rises to the right position, the swing support block 352 can be reset to hold the material tray 200. The connection block 351 and the swing support block 352 are provided with several groups to ensure that the material tray 200 is stably held.

[0056] The loading assembly 33 and the unloading assembly 35 are respectively provided with a plurality of limiting columns 36 for surrounding and limiting the stacked material trays 200.

The material tray 200 loaded with materials is placed on the bearing plate 326 of the first bearing component 323. Under the action of the twelfth driving member 332 and the thirteenth driving member 333, the cross plug plate 331 can support the material trays 200 above the second to last layer. The eleventh driving member 327 drives the clamping block 328 to clamp the two ends of the material tray 200. Under the action of the eighth driving member 325, the bearing plate 326 moves downward by a certain distance to make the penultimate layer separate from the upper material tray 200. The seventh driving member 321 drives the bearing plate 326 of the first bearing component 323 to move downward. The plate 326 moves the material tray 200 loaded with materials to the top of the positioning support frame 34, and the eighth driving member 325 of the first supporting component 323 drives the supporting plate 326 to move downward so that the supporting plate 326 loaded with materials falls on the positioning support frame 34 for the loading and handling device 5 to grab the materials. At the same time, the seventh driving member 321 drives the supporting plate 326 of the second supporting component 324 to move the empty material tray 200 to the bottom of the unloading component 35, and the eighth driving member 325 of the second supporting component 324 drives the supporting plate 326 to move upward so that the swing support block 351 can be squeezed and rotated to make way. After the material tray 200 rises into place, the swing support block 352 can be reset to hold the empty material tray 200. After the conveying is completed, the conveying drive mechanism 32 moves down and resets.
