[0038] Further, the lifting module 200 comprises a second guide rail 210, a second sliding block 220, a second driving member 230 and a second lead screw, the second guide rail 210 is fixedly connected with the first sliding block 130, the second sliding block 220 is in sliding connection with the second guide rail 210, the output end of the second driving member 230 is in transmission connection with the second sliding block 220, the second lead screw is mounted on the second guide rail 210, either end of the second lead screw is connected with the output end of the second driving member 230, the second sliding block 220 is in rotatable connection with the second lead screw, and the second driving member 230 drives the second lead screw to rotate, thereby driving the second sliding block 220 to do reciprocating linear motion on the second guide rail 210.

[0039] That is, it can be understood that the lifting module 200 and the linear motion module 100 have the same structure, and both realize the reciprocating movement of the components in a straight line through the linear slide module.

[0045] Beneficially, the floating design of the connecting pipe 430 can absorb the impact force when the assembly adsorbs the metal sheet and the impact force when the metal sheet is placed and cut by the cutting mechanism 500, so as to protect the metal sheet, avoid the deformation of the metal sheet, and help to reduce the production loss. Moreover, the modular design of the connecting pipe 430 and the suction nozzle 420 can realize the replacement of the suction nozzle 420, reduce the downtime, and improve the production efficiency.
