Protective laser welding equipment with cooling function

Abstract

The invention relates to protective laser welding equipment with a cooling function. The equipment comprises a base, a support rod, a lifting device, a connecting box, a connecting column, a welding head and a worktable, and further comprises a protecting mechanism and a cooling mechanism; the protecting mechanism comprises a protective cover, a first spring, a driving module, two moving modules and two limiting modules; the moving modules comprise rotating discs, pull wires, rotating shafts and two first bearings; the cooling mechanism comprises a connecting pipe, an air extracting pump, an intake pipe, a fixed box, an exhaust pipe and a cooling pipe; and a refrigerating rod, a flow separation plate, an activated carbon filter screen and a replacement module are arranged in the fixed box.Through the cooling mechanism, the protective laser welding equipment with the cooling function realizes the cooling work of workpieces on the worktable to prevent scald of users by high-temperatureworkpieces, so that the safety is improved; and through the protecting mechanism, the shielding of the welding head is realized, flame during welding is prevented from splashing to the users, and thesafety is greatly improved.

Description

technical field [0001] The invention relates to the field of laser equipment, in particular to a protective laser welding equipment with a cooling 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] When the existing laser...

Problems solved by technology

[0003] When the existing laser welding equipment performs welding work, it will generate flames, which are easy to splash on the user, posing a threat to the personal safety of the user and reducing the safety of the existing laser welding equipment. Not only that, the existing Laser welding equipment The temperature of the workpiece completed by the welding machine is relatively high, which is easy to burn the user, thus greatly reducing the safety of the existing laser welding equipment
