By placing a weight on the load-bearing table 210, the load-bearing table 210 is lowered, and the adsorption assembly 300 is raised to a certain height by the principle of leverage, and then attached to the warped board.

In addition, in order to use different warped boards, different weights can also be replaced to adjust the height of the jacking baffle 310.

[0033] In order to realize the adsorption function, a plurality of adsorption holes 311 are uniformly arranged on the jacking baffle 310, and in order to create a vacuum state in the shell 100 as much as possible, the jacking baffle 310 and the shell 100 are both rectangular, the size of the jacking baffle 310 is equal to the size of the inner groove of the shell 100, and the height of the end surface of the shell 100 is higher than the bottom surface of the jacking baffle 310. Preferably, a sealing strip can also be arranged between the jacking baffle 310 and the shell 100, so that the sealing strip is attached to the side surface of the jacking baffle 310, so as to realize the pulling of the warped part of the warped plate through the adsorption hole 311.

[0034] It should be emphasized that the two sides of the shell 100 are also provided with a vacuum interface 110 for extracting air in the shell 100, thereby realizing the adsorption function.
