The incoming material sorting component 31 includes a bracket 311, a rotating shaft 312 rotatably mounted on the bracket 311, and a rotating motor 313 driving the rotating shaft 312 to rotate. An adapter plate 314 is fixedly connected to the rotating shaft 312, and a silicon wafer placement seat 315 is provided on the adapter plate 314. A backlight plate 316 is provided on the silicon wafer placement seat 315. The rotating motor 313 drives the rotating shaft 312 to rotate, thereby rotating the adapter plate 314. The silicon wafer placement seat 315 is used to place silicon wafers. Sorting cylinders 317 are symmetrically arranged on the adapter plate 314, and sorting push plates 318 are installed on the sorting cylinders 317. The sorting cylinders 317 are located outside the silicon wafer placement seat 315. The sorting cylinders 317 are used to sort multiple silicon wafers neatly.

[0033] In this embodiment, the sorting and inspection component 32 includes a horizontal lead screw module 321, a vertical drive module 322 slidably mounted on the horizontal lead screw module 321, and a binocular camera group 323 slidably mounted on the vertical drive module 322.

[0037] The working process of the photovoltaic cell packing and stacking inspection device of this utility model is as follows:

[0038] First, the motor 213 is rotated to make the adapter plate 314 horizontal. Then, the suction cup structure 223 of the first material picking component 22 picks up the silicon wafers in the material box 21 and places them on the silicon wafer placement seat 315 from above. After all the silicon wafers in the material box 21 are placed on the silicon wafer placement seat, the aligning cylinder 317 is activated, causing the aligning push plate 318 to press against the multiple stacked silicon wafers. Then, the motor 313 is rotated to reset the adapter plate 314. The binocular camera group 333 is used to check whether the edges of the stacked silicon wafers are even. If there are any unevenness problems, the aligning cylinder 317 is used to align them. After aligning, the gripper structure 413 picks up the entire stack of silicon wafers and places them at the inspection station 421. The four-sided camera 423 and the chamfering camera 424 on the annular support plate 4221 are used to detect defects such as edge chipping and fragmentation, as well as the number of stacked layers.
