Safety laser welding device with smoke treatment function

Abstract

The invention relates to a safety laser welding device with a smoke treatment function. The device comprises a worktable, a top plate, a connecting column, a welding head and two supporting columns, and further comprises a protection mechanism and two purifying mechanisms, the protection mechanism comprises a protection cover, a limiting assembly and two lifting assemblies, each lifting assembly comprises a first motor, a fixed block, a gear and a rack, and each purifying mechanism comprises a connecting box, a purifying box, a filter net, a suction nozzle, a hose, a connecting pipe, a piston,a driving assembly, a connecting assembly, a cleaning assembly and two waste boxes. According to the safety laser welding device with the smoke treatment function, through the protection mechanism, the sheltering function of the welding head is achieved, sparks generated during welding can be prevented from being splashed to a body of a user, device safety is improved, through the purifying mechanisms, the smoke purifying function is achieved, the smoke is prevented from being directly released into atmosphere, the surrounding air environment is not affected, and the device environment friendliness is improved.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a safe laser welding equipment with fume treatment function. 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] The existing laser wel...

AI Technical Summary

Problems solved by technology

[0003] The existing laser welding equipment will generate more sparks during welding, and the sparks are easy to splash on the user, which increases the probability of injury to the user and reduces the safety of the existing laser welding equipment. Not only that, the existing When the advanced laser welding equipment is welding, it will produce harmful fumes. If the harmful fumes are directly released into the atmosphere, it will affect the surrounding air environment and pose a threat to the health of users, thereby reducing the existing laser welding equipment. environmental protection
