The connection between the first linear module 201, the second linear module 202, and the second support frame 101 is made by bolts. A positioning structure 3 is connected to the sliding table of the second linear module 202. The driving direction of the second linear module 202 is perpendicular to the driving direction of the first linear module 201. Since the driving directions of the first linear module 201 and the second linear module 202 are perpendicular, bidirectional adjustment in the X and Y directions is possible.

After loosening the hand-tightening bolt 309, the second connecting plate 307 can be moved up and down, thereby allowing the CCD vision inspection camera 308 to be moved up and down to adjust the shooting distance of the CCD vision inspection camera 308. After tightening the hand-tightening bolt 309, the position of the second connecting plate 307 can be fixed.

[0023] Furthermore, a base plate 302 is connected to the bottom of the connecting frame 301, and a supplementary light 303 is connected to the bottom of the base plate 302.
