Intelligent welding mechanical arm for new energy automobile door

Abstract

The invention discloses an intelligent welding mechanical arm for a new energy automobile door, which belongs to the technical field of mechanical arms and comprises a mechanical arm support, a large mechanical arm and a small mechanical arm which are arranged on the mechanical arm support, a sleeve for protecting a welding wire, a torsion buffer support assembly for supporting the sleeve and a fixed support assembly, the fixed supporting assembly is fixed to the mechanical arm support, and a central spindle extends outwards from the connecting joint of the large mechanical arm and the small mechanical arm. The torsion buffering and supporting assembly comprises a rotating sleeve, a connecting and supporting part and a welding wire supporting part, and the rotating sleeve is in running fit with the mandrel. When the joint of the mechanical arm is bent repeatedly, deformation of the welding wire can be buffered, the instantaneous bending amplitude of the welding wire is reduced, and it is guaranteed that the welding process is carried out smoothly.

Description

technical field [0001] The invention belongs to the technical field of mechanical arms, and in particular relates to an intelligent welding mechanical arm of a new energy vehicle door. Background technique [0002] Welding robots mainly include two parts: robots and welding equipment. The robot consists of a robot body and a control cabinet. The welding equipment, taking arc welding and spot welding as an example, consists of a welding power source, a wire feeder, and a welding torch. For intelligent robots, there should also be sensing systems, such as laser or camera sensors and their control devices. The production of existing new energy vehicles mostly adopts fully automated systems. During the welding process of new energy vehicle doors, the welding rod needs to be continuously consumed, and the welding rod needs to be continuously transported from the winding mechanism to the welding gun part at the end of the robot. Conveying and maintaining a conveying state for a...

AI Technical Summary

Problems solved by technology

The production of existing new energy vehicles mostly adopts a fully automated system. In the process of welding the doors of new energy vehicles, welding rods need to be continuously consumed. The welding rods need to be continuously transported from the winding mechanism to the welding torch at the end of the robot. If the welding wire is directly Conveying, keeping a conveying state for a long time, at this time, the welding wire often cannot keep up with the instantaneous bending speed when the manipulator is working, and the repeated rotation of the manipulator joint for a long time will easily lead to the breakage of the welding rod, resulting in the interruption of the welding process when the manipulator is working , which brings a lot of trouble to the welding work on site, thus affecting the delivery of new energy vehicles
