[0011] The working principle of the above-mentioned automatic bottom-replenishing production line for cookware is as follows:

[0012] During operation, the negative film and the aluminum sheet are first stacked on the negative film feeding mechanism and the aluminum sheet feeding mechanism respectively, and the negative film grabbing assembly and the aluminum sheet grabbing assembly are driven by the first multi-axis robotic arm to move to the top of the negative film and the aluminum sheet to be transported, and then the negative film grabbing assembly and the aluminum sheet grabbing assembly are used to grab the negative film and the aluminum sheet to be transported, and then the negative film grabbing assembly and the aluminum sheet grabbing assembly are driven by the first multi-axis robotic arm to approach the bottom-replacing station of the hydraulic press, and the negative film is first transported to the top of the bottom-replacing station of the hydraulic press and placed, and then the aluminum sheet grabbing assembly is driven to rotate a certain angle, and the aluminum sheet is transported to the top of the bottom-replacing station of the hydraulic press, and then placed, at this time, the aluminum sheet is located directly above the negative film; the negative film is squeezed downward by the hydraulic press, so as to cold-press the negative film into the aluminum sheet; the bottom-replacing piece is transported to the unloading conveying mechanism by the second multi-axis robotic arm, and finally the bottom-replacing piece is transported downward by the unloading conveying mechanism, and thus a round of bottom-replacing work is completed.
