The auxiliary pressing assembly 8 of the present embodiment is provided with four sets, and each edge block 53 is provided with two auxiliary pressing assemblies 8 on the two ends on the opposite side of the other edge block. The four side walls of the product are pressed against the jig 2 by the two edge blocks and the four auxiliary pressing blocks 81.

[0079] Referring to FIG. 6, FIG. 9 and FIG. 10, when the horizontal moving plate 31 slides, in order to prevent the auxiliary pressing block 81 from interfering with the horizontal moving plate 31, the telescopic driving member 82 is shortened, so that the auxiliary pressing block 81 rotates on the edge pressing block 53, thereby keeping a vertical state. After the horizontal moving plate 31 puts the product into the jig 2, the horizontal moving driving member 32 moves the horizontal moving plate 31 to a safe area, then the jacking driving member 73 retracts the jacking rod 72 into the jig 2, the telescopic driving member 82 rotates the auxiliary pressing block 81 and finally makes the bottom of the auxiliary pressing block 81 keep the same level with the bottom of the edge pressing block 53. Then the sliding driving member drives the sliding plate 51 to move downward, thereby making the edge pressing block 53 and the auxiliary pressing block 81 jointly press the four side edges of the product, so that the product is pressed in the positioning groove 24 and forms a sealed second vacuum cavity between the product and the positioning groove 24, which facilitates the jig 2 to adsorb the product and improves the adsorption effect of the jig 2 on the product.

[0080] The working principle of the embodiment 2 of the present application is as follows:

[0081] The telescopic driving member 82 is shortened to make the auxiliary pressing block 81 keep a vertical state, so as to avoid interference with the movement of the horizontal moving plate 31. After the horizontal moving plate 31 moves the product into the jig 2 and moves to a safe area, the telescopic driving member 82 is elongated to make the auxiliary pressing block 81 keep the same level with the edge pressing block 53, so as to jointly press the four side edges of the product in the positioning groove 24 and form a second vacuum cavity, thereby improving the adsorption effect of the jig 2 on the product.

[0082] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
