Specifically, a suction cup mounting plate 500 for mounting the vacuum suction cup module 400 is provided on the moving end of the servo screw module 300. The vacuum suction cup module 400 is fixed on the moving end of the screw module by the suction cup mounting plate 500 to ensure the stability of the suction cup structure installation, and at the same time facilitate the disassembly and replacement of suction cup structures of different specifications.

[0024] like Figures 1 to 3 As shown, in order to ensure the stability of the screw structure, in this embodiment, a module mounting plate 600 arranged along the length of the screw is provided on the outside of the screw of the servo screw module 300. The overall structure of the screw module is strengthened by the module mounting plate 600 to ensure the stable operation of the screw structure. In practical applications, the vacuum suction cup module 400 includes a Bernoulli suction cup module 410, and a pressure regulating valve 420 and a solenoid valve 430 are provided on the Bernoulli suction cup module 410; in this way, the negative pressure of the suction cup structure can be controlled by the pressure regulating valve 420, and the gas circuit can be controlled by the battery valve to realize the automatic release of the material grab box.
