Specifically, the lifting mechanism 12 drives the first supporting part to move (rise or fall) along the axial direction of the material storage frame 112, thereby driving the product to be tested on the first supporting part to rise or fall. When the first detector 14 detects that there is no product to be tested at the feeding position of the first supporting part, the lifting mechanism 12 is driven to drive the first supporting part to rise, so that there is a product to be tested at the feeding position, which is convenient for the feeding mechanism to absorb. The sensor assembly 13 includes a first sensor 131 and a second sensor 132. The first sensor 131 and the second sensor 132 are arranged in parallel, and the height of the first sensor 131 is at least higher than The second position sensor 132 is set at a height, the first sensor 131 is used to limit the maximum conveying height allowed by the first supporting part, and the second sensor 132 is used to limit the minimum conveying height allowed by the first supporting part.

Specifically, the anti-stacking mechanism 15 can be a blowing part 151a. When the product to be tested is adsorbed and moved upward, the blowing part 151a blows air to the edge of the product to be tested.
