Description

Technical Field

[0001] The present invention relates to the technical field related to industrial robots, and in particular to a mold production welding robot. Background Art

[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 chemicals. Compared with traditional industrial equipment, industrial robots have many advantages. For example, robots have ease of use, high level of intelligence, high production efficiency and safety, easy management and significant economic benefits, which enable them to operate in high-risk environments. With the continuous development of welding automation technology, automatic welding robots are increasingly 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 robot, the conveying device needs to wait for the welding to be completed before it can convey 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.

[0004] In order to solve the above problems, after searching, the patent with the announcement number CN107962321B discloses a welding robot production line, which proposes "comprising 6 groups of robot welding devices arranged in sequence, the robot welding device comprises a turning frame external axis motor and a connecting rod, a turning frame is provided on the right side of the turning frame external axis motor, a first turning fixture is provided on the upper surface of the left end of the turning frame, a second turning fixture is provided on the upper surface of the right end of the turning frame, a cooling water device is provided on the back side of the left end of the turning frame, a robot control cabinet is provided on the right side of the cooling water device, and the front surface of the robot control cabinet is provided.

A cooling water device is provided on the machine body, and multiple tubes are provided inside the cooling water device. The tubes are filled with condensate, and the condensate is used as a medium to discharge the heat generated by the machine body during operation, thereby reducing the maintenance frequency of the machine body and bringing convenience to the user. Although the heat generated during operation can be discharged through the condensate, the conveyor still needs to wait when welding the same welding point, and the mold needs to be re-set and the machine needs to be adjusted when switching to a mold of a different shape.

[0005] In view of this, we conducted in-depth research on the above issues, which led to the present case. Summary of the Invention
