AI Technical Summary

Technical Problem

Existing automatic inkjet printing and punching devices require moving the inkjet printing and punching devices when printing and punching on arms of different diameters, resulting in low efficiency.

Method used

An automatic coding and punching device with a wrist arm was designed. By adjusting the distance between the wrist arm and the coding and punching components through the support and drive components, the distance between the apex of the wrist arm with different diameters and the coding and punching components on the same vertical plane is kept consistent, so that coding and punching can be performed without moving the coding and punching components.

Benefits of technology

It improves the efficiency of coding and punching, and ensures the quality of coding and punching for arms of different diameters.

Abstract

The utility model discloses an automatic code spraying and punching device for a cantilever, which belongs to the technical field of cantilever production and comprises a bracket, a code spraying component and a punching component are arranged on the bracket, the code spraying component can spray codes on the cantilever on the bracket, and the punching component can punch the cantilever on the bracket. A first distance is arranged between the vertex of the cantilever and the code spraying assembly and the punching assembly, a supporting assembly is arranged on the bracket and makes contact with the cantilever so as to support the cantilever, and a driving assembly is connected to the supporting assembly. The supporting assembly enables the distances between the vertexes of the cantilevers with different diameters and the code spraying assembly and the punching assembly on the same vertical plane to be first distances through the driving assembly. The distances between the vertexes of the cantilevers with different diameters and the code spraying assembly and the punching assembly are the first distances, the code spraying assembly and the punching assembly can perform code spraying and punching on the cantilevers without moving positions, the punching and code spraying efficiency is improved, and meanwhile the punching and code spraying quality is improved.
