Optical fiber laser welding device

Abstract

The invention discloses an optical fiber laser welding device, and relates to the field of laser welding. The optical fiber laser welding device comprises a welding machine, the outer side of the welding machine is connected with a connecting ring, the outer side of the connecting ring is connected with a spring rotating shaft, the outer side of the connecting ring is rotatably connected with a connecting block through the spring rotating shaft, and goggles are arranged in the connecting block. A clamping block is connected to one side of the connecting block, and a moving block is connected to the outer side of the clamping block. Through the arrangement of the welding machine, the connecting ring, the spring rotating shaft, the connecting block, the goggles, a push block, the clamping block, the moving block, a clamping groove, a spring and a temperature sensor, when the welding machine is operated to weld a workpiece, the push block can be pushed, and the goggles can be bounced offunder the action of the spring rotating shaft. An operator can watch welding through the bounced goggles during welding, so that eyes of the operator are prevented from being in direct contact with high light generated by welding, and damage to the eyes of the operator is reduced.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to an optical fiber laser welding device. 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. It was mainly used for welding thin-walled materials and low-speed welding in the 1970s. The process is of heat conduction type, 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 parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted and a specific molten pool is formed. Due to its unique The advantages have been successfully applied in the precision welding of micro and small parts. [0003] Existing fiber laser welding devices do ...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing optical fiber laser welding device does not equip the operator with goggles for blocking the strong light, and some operators often give up wearing the goggles during operation because of the heavy weight of the goggles. Watching laser welding without barriers will cause eye injury, and the existing light laser welding device has a simple structure and single function, and cannot clean the objects after welding in time, and the welding black marks left on the objects will be damaged after a long time. It is more difficult to clean, resulting in unsightly welding traces, and the existing fiber laser welding device cannot properly dissipate heat for the welding machine after working for a long time. If the welding machine does not dissipate heat for a long time, the internal parts will be damaged due to high temperature, thus To solve the problem of short service life of the welding machine, a fiber laser welding device is provided
