Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a cabinet frame flexible welding workstation. Background Art

[0002] Welding is an indispensable processing method in the modern machinery manufacturing industry. It occupies an important position in the automobile manufacturing, engineering machinery, motorcycle and other industries. In the past, manual welding processing was a heavy task. As the welding accuracy and speed requirements of many welded structural parts are getting higher and higher, ordinary workers have been unable to do this job. In addition, the arc, sparks and smoke during welding can cause harm to the human body. The complexity of the welding manufacturing process, labor intensity, product quality, batch requirements, etc., make the welding process extremely urgent for automation and mechanization. At the same time, the production plan is not easy to control, the production cost is high, and the production efficiency is low. Realizing robot automatic welding instead of manual welding has become the ideal and pursuit goal of generations of welders. The welding robot is a revolutionary advancement in welding automation. It breaks through the traditional way of rigid automation of welding and opens up a flexible automated production method.

[0003] Rigid automated production equipment is usually dedicated and only suitable for medium and large batches of automated production. Therefore, for a long period of time, manual welding is still the main welding method in the welding production of medium and small batches of products. The emergence of welding robots has made it possible to automatically weld small batches of products. Since the robot has a teaching and reproducing function, it only takes one person to teach the robot once to complete a welding task, and then the robot can accurately reproduce each step of the teaching. If the robot is required to do another job, there is no need to change any hardware, just teach or program the robot again. Therefore, on a welding robot production line, different products can be automatically produced at the same time. Utility Model Content
