Laser welding equipment with high safety

Abstract

The invention relates to laser welding equipment with high safety. The laser welding equipment comprises a worktable, a base, a top plate, a lifting device, a lifting plate, a welding head and two struts, and further comprises a protection mechanism and two cleaning mechanisms, wherein the protection mechanism comprises a moving plate, a first spring, two connection assemblies, two drive assemblies and four protective plates, each cleaning mechanism comprises a fixed box, an airbag, a pressing plate, a second spring, an air inlet pipe, a connecting pipe, a connecting box, a fixing rod and tworeciprocating assemblies. According to the laser welding equipment with high safety, the protection mechanism is arranged, so that the protective plates can protect the worktable and the welding headfrom the four sides of the worktable during welding, and the sparks generated during welding are prevented from splashing onto users, thus improving the safety of the equipment; and a dust removal mechanism is arranged, dust impurities on workpieces can be blown away, so that the cleaning function is realized, and the impurities on the workpieces is prevented from affecting the welding effect.

Description

technical field [0001] The invention relates to the field of laser equipment, in particular to a laser welding equipment with high safety. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. 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 inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts. [0003] Existing laser welding equipment will gen...

AI Technical Summary

Problems solved by technology

[0003] Existing laser welding equipment will generate a large amount of sparks when performing welding work, and the sparks are easy to splash on the user, thereby posing a threat to the personal safety of the user and reducing the safety of the existing laser welding equipment, not only that , Impurities and dust are easy to adhere to the workpiece with welding. If it is not cleaned in time, it will affect the welding effect and reduce the welding quality, thus greatly reducing the practicability of the existing laser welding equipment.
