Description

Technical Field

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemical industry. Compared with traditional industrial equipment, industrial robots have many advantages. For example, robots are easy to use, have a high level of intelligence, high production efficiency and safety, are easy to manage, and have significant economic benefits, which enable them to operate in high-risk environments. With the continuous development of welding automation technology, more and more automatic welding robots are used in the existing welding process to weld the workpieces to be welded. In industrial manufacturing, manual welding efficiency is low when welding molds and welding connectors, and the welding effects are uneven, so there is a special need for a mold production welding robot.

[0003] However, in the existing welding robots, the conveying device needs to wait for the welding to be completed before conveying the mold again, which affects the welding work efficiency. In addition, the mold needs to be positioned during welding. When it is necessary to switch to a mold of a different shape, the mold needs to be re-set and the machine needs to be adjusted, which consumes a lot of manpower. In addition, the adjustment process will also cause waste of materials of the workpiece to be welded and the welding connector.
