Description

Technical Field

[0001] The utility model relates to the technical field of gas purification processing equipment, in particular to gas purification equipment for welding robots. Background Art

[0002] A welding robot is an industrial robot that performs welding (including cutting and spraying) and is used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the robot's last axis is usually a connecting flange that can be connected to different tools or end effectors. A welding robot is an industrial robot that has a welding tongs or welding (cutting) gun connected to its end axis flange, enabling it to perform welding, cutting or thermal spraying.

[0003] When a welding robot is welding an object, a large amount of welding smoke is generated around it, causing the surrounding air environment to be polluted. Therefore, gas purification equipment is needed. The existing gas purification equipment uses simple filter cotton for filtering during use, and the filter cotton used is not convenient for the staff to replace. At the same time, the filtering effect of collecting welding smoke is not good, resulting in the exhaust gas still retaining impurities that pollute the air. Over time, it causes certain harm to the health of the surrounding welding workers.

[0004] According to the publication number: CN218695308U, a welding device with a fume purification function is proposed. The utility model includes an operating table, a wind shield is connected to the outer wall of the top of the operating table by bolts, a lifting mechanism is provided at the bottom of the operating table, the lifting mechanism includes a placement plate, and an adjustment mechanism is provided on the upper inner wall of the wind shield. The utility model can prevent the wind from blowing the exhaust gas generated during welding to other locations, can make the workers relatively away from the welding place, reduce safety hazards, improve practicality, can effectively reduce the content of harmful gases in the exhaust gas generated during welding, avoid affecting the health of the workers, and improve environmental protection.

[0005] According to the above introduction, the gas purification equipment used by the welding robot during welding has a simple internal filtering structure, resulting in unclean fume purification.

In order to solve the above problems, we have proposed an improved welding robot gas purification equipment. Utility Model Content
