[0027] Specifically, it further includes a supplementary lighting component 6, and the supplementary lighting component 6 is installed on the bracket 5 and is located below the vision component 3. By adding the supplementary lighting component 6, the imaging effect of the vision component 3 can be improved, thereby improving the adjustment effect of the concave plate assembly 2. Further, the supplementary lighting component 6 includes a light source 61 and a light source mounting base 62, and the light source 61 is rotatably mounted on the bracket 5 through the light source mounting base 62 to adjust the supplementary lighting angle of the light source 61.

[0028] Specifically, the vision component 3 includes a suspension 31 and a CCD camera 32 installed on the suspension 31, and the suspension 31 is installed on the upper part of the bracket 5. The CCD camera 32 can be used to obtain the image information of the concave plate assembly 2, and by connecting the CCD camera 32 and the bracket 5 through the suspension 31, it can be used to adjust the fixed position of the CCD camera 32 so that the CCD camera 32 is located above the concave plate assembly 2, improving the image acquisition effect.

[0029] Specifically, the moving platform 1 is an XY-axis bidirectional moving platform. Further, the XY-axis bidirectional moving platform includes an X-axis moving platform 11 at the bottom, and a Y-axis moving platform 12 disposed above the X-axis moving platform 11 and movable relative to the X-axis moving platform 11 in the X-axis direction.
