Laser welding weldment fixing device with infrared distance measurement function

Abstract

The invention discloses a laser welding weldment fixing device with an infrared distance measurement function. The laser welding weldment fixing device comprises a laser light source, a baffle assembly, an infrared induction emitting device, an infrared induction receiving device, a mechanical gripper, a guide piece, a telescopic guide rod and a control unit. The baffle assembly comprises a first baffle and a second baffle, the two baffles are arranged in parallel in the vertical direction, a groove is formed in a certain position of the inner side of each baffle in the horizontal direction of the two baffles, and the guide part is arranged in the groove; the control unit comprises a control system and a control box, one end of the control box can slide along the guide piece in the groove of the first baffle, the other end of the control box is connected with the weldment, an infrared induction emitting device is arranged on the side face of the control box, and an infrared induction receiving device is arranged within the horizontal induction distance of the emitting device; the mechanical gripper grabs the weldment and turns over the weldment, and the end, away from the weldment, of the mechanical gripper is in sliding connection with the guide piece of the second baffle through a telescopic guide rod; and the laser light source is fixed above the welding piece.

Description

Technical field: [0001] The present invention relates to the technical field of a device for laser welding welding parts, in particular to a laser welding welding part fixing device with infrared distance measurement Background technique: [0002] In the prior art, laser welding is a high-efficiency and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important methods for the application of laser material processing technology. [0003] In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the width, energy, and peak power of the laser pulse Parameters such as and repetition frequency make the workpiece melt and form a specific molten pool. Due to its unique advantages, it has been succe...

AI Technical Summary

Problems solved by technology

[0009] The present invention aims to overcome the problems in the prior art that the welding distance cannot be accurately determined during the laser welding process, the defocus amount needs to be manually measured before each welding, and the real-time monitoring of the weldment cannot be carried out, and solves the problems caused by the laser welding weldment fixing. It is difficult to accurately determine the welding distance and the technical problem of manually measuring the defocus amount before each welding, and at the same time solves the situation that it is impossible to monitor the welding process and evaluate the welding effect in real time, and provides an accurate, simple and efficient weldment fixing device
