Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, specifically to a wire feeding mechanism for a welding robot. Background Technology

[0002] Welding, as the "tailor" of industry, is a very important processing method in industrial production. The quality of welding has a decisive impact on the quality of products. At the same time, due to the presence of welding fumes, arc light, and metal spatter, the working environment of welding is very harsh. With the development of advanced manufacturing technology, the automation, flexibility, and intelligence of welding product manufacturing has become an inevitable trend. The use of welding robots has become a major indicator of the intelligence of welding technology. When welding robots are performing welding, welding wire needs to be fed to the welding robot through a wire feeding device.

[0003] In existing technologies, welding wire is usually fed by rotating a wire feeding wheel. However, in actual use, the surface of the welding wire is prone to being covered with a lot of dust or impurities. Since the welding wire cannot be cleaned, impurities can easily fall into the weld, thus compromising the quality of the weld. Therefore, it is necessary to improve the wire feeding mechanism of a welding robot to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wire feeding mechanism for a welding robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire feeding mechanism for a welding robot, comprising a wire feeder body, a door on the front of the wire feeder body, a wire winding spool inside the wire feeder body, a wire feeding drive wheel inside the wire feeder body, a cleaning mechanism inside the wire feeder body, and a limit mechanism outside the cleaning mechanism.

[0006] Preferably, the cleaning mechanism includes a first bidirectional threaded rod, which is rotatably mounted inside the wire feeder body. A square rod is rotatably mounted inside the wire feeder body. A protective shell is fixedly mounted on the top of the wire feeder body. A worm gear is fixedly mounted on the outside of the square rod. A worm is meshed with the outside of the worm gear. The worm is rotatably mounted to the protective shell. A threaded sleeve is threaded onto the outside of the first bidirectional threaded rod. A connecting shell is fixedly mounted on the outside of the threaded sleeve. A first rotating drum is rotatably mounted inside the connecting shell. A first pulley is fixedly mounted on the outside of the first rotating drum. A transmission belt is driven onto the outside of the first pulley. A second rotating drum is rotatably mounted inside the connecting shell. A second pulley is fixedly mounted on the outside of the second rotating drum. A square column is slidably mounted on the inner wall of the second rotating drum. A connecting plate is fixedly mounted on one end of the square column. A cleaning cotton is provided on the end of the connecting plate away from the square column to facilitate the cleaning of the welding wire.

[0007] Preferably, a through groove is provided inside the first rotating drum at the position corresponding to the square rod, and the square rod is slidably installed in the through groove to facilitate the lifting and rotation of the first rotating drum.

[0008] Preferably, the limiting mechanism includes a connecting seat, which is fixedly installed on the outside of the connecting shell. A second bidirectional threaded rod is rotatably installed inside the connecting seat, and a clamping rod is threaded on the outside of the second bidirectional threaded rod. A limiting post is fixedly installed on the inner wall of the connecting seat. A rotating wheel is rotatably installed at the end of the square post away from the connecting plate. The clamping rod is slidably installed with the rotating wheel to facilitate the limiting operation of the square post.

[0009] Preferably, a through hole is provided inside the clamping rod at a position corresponding to the limiting post, and the limiting post is slidably installed in the through hole to facilitate the limiting operation of the clamping rod.

[0010] Compared with the prior art, this utility model provides a wire feeding mechanism for a welding robot, which has the following advantages:

[0011] 1. The wire feeding mechanism of this welding robot, through its cleaning mechanism, facilitates the movement of the threaded sleeve by rotating the first bidirectional threaded rod during use. This movement facilitates the movement of the connecting shell, allowing the cleaning cotton to come into contact with the welding wire and enabling the cleaning of the welding wire during the feeding process. This ensures the cleanliness of the welding wire surface. By rotating the worm gear, the worm wheel and square rod can be rotated. With the cooperation of the first drum, the first pulley, the transmission belt, the second drum, and the second pulley, the connecting disc can be rotated, facilitating contact between the welding wire and the clean area of ​​the cleaning cotton. This eliminates the need for frequent disassembly and cleaning of the cleaning cotton, ensuring its high utilization rate.

[0012] 2. The wire feeding mechanism of this welding robot, through the setting of the limiting mechanism, allows the clamping rod to move towards the rotating wheel by rotating the second bidirectional threaded rod during use, with the cooperation of the limiting column. This facilitates the clamping of the rotating wheel and limits the square column without affecting its rotation, thus preventing the connecting plate from shaking up and down.
