High-safety laser welding equipment

Abstract

The invention relates to high-safety laser welding equipment. The high-safety laser welding equipment comprises a base, a workbench, an air cylinder, a dustproof cover, a welding device, a supportingplate and two supporting columns, and further comprises a cooling mechanism and a purifying mechanism, the purifying mechanism comprises an air collecting box, two purifying assemblies and a pluralityof suction nozzles, each purification assembly comprises a purification box, an air exhaust unit, a driving plate, a driving rod, a lead screw, a first spring, a ball screw bearing and two first bearings, the cooling mechanism comprises a fixing box, a cooling pipe, a connecting pipe, two power assemblies and a plurality of cooling fins, and each power assembly comprises a power box, a power plate, a second spring, an air inlet pipe and a power disc. According to the high-safety laser welding equipment, the purification function is achieved through the purification mechanism, and dust is prevented from polluting the surrounding environment and being absorbed by a human body, so that harm to the body health of a user is reduced; and the function of cooling a workpiece is achieved through the cooling mechanism, so that the situation that due to the fact that the temperature of the workpiece is high, the user is scalded is avoided.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a laser welding device 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] When the existing laser welding equipment is wo...

AI Technical Summary

Problems solved by technology

[0003] When the existing laser welding equipment is working, the temperature of the workpiece will increase. If the user directly contacts the workpiece, he will be easily burned by the high temperature workpiece, thereby reducing the safety of the existing laser welding equipment. Not only In this way, the existing laser welding equipment will generate a lot of dust when it is working. If the dust is directly discharged into the atmosphere, it will easily cause environmental pollution and be easily absorbed by the human body, thereby endangering the health of the user and reducing the Reliability of Existing Laser Welding Equipment
