[0013] By adopting the above technical solution, a customized adsorption channel can be formed by combining the adsorption groove and adsorption channel with the customized sandwich plate. These adsorption channels can be flexibly adjusted according to different specifications of products to meet the adsorption requirements of different products.

[0014] Optionally, the plurality of micro adsorption holes are distributed in a matrix shape on the upper plate of the adsorption fixture.

[0019] By adopting the above technical solution, the upper plate and the lower plate of the adsorption jig can be fixed by the fixing component, and the upper plate and the lower plate of the adsorption jig can be disassembled by adjusting the fixing component.

[0020] Optionally, the fixing assembly includes a plurality of fixing bolts, and the fixing bolts are threadedly connected to the upper plate of the adsorption jig and the lower plate of the adsorption jig at the same time.

[0021] By adopting the above technical solution, the rod of the fixing bolt can be separated from the lower plate of the adsorption fixture by rotating the fixing bolt, thereby quickly separating the two.
