Safe and healthy laser welding equipment

Abstract

The invention discloses safe and healthy laser welding equipment. The equipment comprises a base, a main machine, a platform, a top plate, a plane moving device, a laser, a purification mechanism, a shielding mechanism and two supporting plates, wherein the shielding mechanism comprises a lifting assembly, a lifting block and two shielding assemblies, the two sides of shielding plates are providedwith concave openings, sealing units are arranged in the concave openings, the purification mechanism comprises an air inlet pipe, a water tank, a water pump, an air outlet pipe, a water injection pipe, a water drainage pipe, a water pumping pipe and a purification box, and a bearing, a water spraying pipe, a swing assembly, a plurality of spray heads and a plurality of purification assemblies are arranged in the purification box. According to the safe and healthy laser welding equipment, a closed space to be formed below the top plate through the shielding mechanism, so that human eyes are prevented from being damaged by lasers, and the eyes of operators can be protected; and moreover, harmful smoke generated during welding can be absorbed through the purification mechanism, so that thepurpose of purifying air is achieved, the respiration health of the operators is protected, and the practicability of the equipment is further improved.

Description

technical field [0001] The invention relates to the field of laser equipment, in particular to a safe and healthy laser welding equipment. 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. The surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through conduction. Control parameters such as energy, width, peak power and repetition frequency of the laser pulse to melt the workpiece and form a specific molten pool. Due to its unique advantages, laser welding has been successfully applied in the precision welding of tiny parts. [0003] However, during the operation of the existing laser welding equipment, the workpiece is melted by high heat to form a molten pool, and at the same time, part of the material will be gasified to f...

Problems solved by technology

[0003] However, during the operation of the existing laser welding equipment, the workpiece is melted by high heat to form a molten pool, and at the same time, part of the material will be gasified to form small particle smoke, which is easily inhaled by the operators and affects the health of the workers. Not only that, laser radiation will also cause certain harm to human eyes. When operators work on laser welding equipment for a long time, their eyesight will also be affected by laser light and will reduce the practicability of existing laser welding equipment.
