The pressing plate 2 is fixedly set at the end of the buffer column 5, and the pressing plate 2 is provided with a clamping area in the middle. It also includes a linear screw motor module 6. The working end of the linear screw motor module 6 is connected to the base 1. The linear screw motor module 6 can drive the base 1 to rise and fall. The clamping part includes two symmetrically arranged clamping blocks. Each clamping block has a hook 17 at its end. The clamping blocks can extend into the junction box 3 and clamp the welding pieces 18 inside the junction box 3 from both sides. The hook 17 can be embedded in the welding area between the welding piece 18 and the junction box 3. The clamping blocks include a first clamping block 7 and a second clamping block 8. A first positioning block 9 is provided on the inner side of the first clamping block 7 near the central clamping area, and a second positioning block 10 is provided on the inner side of the second clamping block 8 near the central clamping area. A first telescopic cylinder 11 and a second telescopic cylinder 12 are provided on the base 1. The working end of the first telescopic cylinder 11 is connected to the first mounting plate 13. The first clamping block 7 and the first positioning block 9 are respectively fixedly mounted on the first mounting plate 13. The working end of the second telescopic cylinder 12 is connected to the second mounting plate 14. The second clamping block 8 and the second positioning block 10 are respectively fixedly mounted on the second mounting plate 14. The base 1 is provided with a first lifting cylinder 19, a first lifting plate 20, a second lifting cylinder 21, and a second lifting plate 22. The working end of the first lifting cylinder 19 is connected to the first lifting plate 20, and the first mounting plate 13 is fixed on the first lifting plate 20.

[0019] The photovoltaic module junction box 3-piece welding inspection mechanism provided in this embodiment works on the following principle: The photovoltaic module junction box 3 is placed below the testing mechanism. The linear screw motor module 6 drives the entire base 1 downward, thereby pressing the pressing plate 2 to position and fix the junction box 3. The buffer column 5 connected to the pressing plate 2 can play a buffering role to avoid excessive pressing pressure that could cause deformation or damage to the junction box 3. After the pressing plate 2 presses the junction box 3, the two lifting cylinders drive the mounting plate downward, thereby causing the positioning block and clamping block on the mounting plate to extend into the junction box 3 and approach the welding piece 18 inside the junction box 3. The positioning block presses on top of the welding piece 18, while the hook 17 at the end of the clamping block is embedded in the welding part between the welding piece 18 and the junction box 3. At this time, the two telescopic cylinders simultaneously drive the two symmetrical clamping blocks to clamp and check whether the welding piece 18 is loose. During the testing process, the camera can take pictures in real time to view the testing situation. Automated testing improves testing efficiency and accuracy.
