AI Technical Summary

Technical Problem

The existing robotic arms used in laser welding equipment lack position detection capabilities, making it difficult to identify plate misalignment and affecting welding accuracy.

Method used

An auxiliary feeding mechanism for laser welding equipment was designed, which includes a feeding robotic arm, a position detection module and a weld detection module. The mechanism uses a laser rangefinder and a CCD camera to detect the position of the plate and the weld in real time, and is equipped with an alarm module to issue an alarm when there is deviation or warping.

Benefits of technology

It enables automatic detection of plate position and weld seam, reducing the decrease in welding accuracy caused by plate offset or warping, and improving the production efficiency and accuracy of laser welding.

Abstract

This application relates to an auxiliary feeding mechanism for laser welding equipment, belonging to the field of laser welding technology. It includes a feeding robotic arm located beside the welding worktable, with a mounting base fixedly installed at the drive end of the arm, and detection plates slidably connected to both sides of the mounting base; a main control console located beside the welding worktable for inputting a start signal; a drive mechanism fixedly installed on the mounting base, with its drive end fixedly connected to the mounting base; a position detection module fixedly installed on the detection plate and connected to the signal output terminal of the main control console; a weld detection module fixedly installed on the detection plate, located below the position detection module, and connected to the signal output terminal of the main control console; and an alarm module fixedly installed on the main control console and connected to the signal input terminals of the position detection module and the weld detection module. This application allows for pre-inspection of the weld between the plate and the support during feeding, ensuring the laser welding effect.
