Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a robot welding gun sandblasting type gun cleaning station. Background Art

[0002] After the robot arc welding torch is used for welding, the internal conductive nozzle, conductive nozzle seat, insulating sleeve, and nozzle inner wall of the welding torch are all adhered with welding spatter and an oxide layer is formed, which leads to poor wire feeding, wire ignition and sticking at the moment of arc starting, poor shielding gas discharge, etc. The above problems seriously affect the welding quality.

[0003] At present, most robot arc welding gun cleaning operations after welding use reamer-type gun cleaning stations. The reamer-type gun cleaning station mainly uses a hollow reamer to perform contact rotation cleaning on the conductive nozzle, the outer wall of the conductive nozzle seat and the inner wall of the nozzle. There are obvious defects in the cleaning process and cleaning results of the reamer-type gun cleaning station. The reamer-type gun cleaning station cannot completely remove the spatter after cleaning, and the oxide layer cannot be cleaned. The remaining spatter and oxide layer may still cause uneven shielding gas discharge and abnormal conductive performance of the conductive nozzle during welding. In more serious cases, the spatter adheres to the insulating components, causing the insulating components to fail and burn the welding gun.

[0004] Similarly, although the early sandblasting gun cleaning station solved some problems of the reamer gun cleaning station, it also brought other problems:

[0005] 1. Most sandblasting gun cleaning stations lack sand separators, and the sand reuse rate is low; and the additional installation of vibrating screen separators on the market has the problems of large size, unresolved vibration noise, and difficulty in cleaning up residual waste.

[0006] 2. The wire cutting and oil injection mechanism is complicated, and the additional parts will increase the probability of failure and increase the working time, affecting the overall beat.

[0007] Therefore, it is necessary to design a robot welding gun sandblasting type gun cleaning station. Utility Model Content

[0008] In view of the technical defects existing in the background technology, the utility model proposes a robot welding gun sandblasting gun cleaning station, which solves the above technical problems and meets the actual needs. The specific technical solution is as follows:

[0009] A robot welding gun sandblasting gun cleaning station comprises a main box, a sandblasting system, a pneumatic system, a solenoid valve control and recovery system, and a wire cutting and oil spraying component. The sandblasting system is located on the top of the main box and is connected to the solenoid valve control and recovery system. The wire cutting and oil spraying component is arranged on one side of the sandblasting system and is connected to the pneumatic system. The solenoid valve control and recovery system comprises a solenoid valve component, a main control system and a recovery system. The solenoid valve component and the pneumatic system are both arranged on the outside of the main box. The recovery system is arranged in the middle of the main box and at the bottom of the sandblasting system.

[0011] Furthermore, the sand storage bin includes a normal sand storage bin and a waste sand storage bin, and a sand shortage sensor is provided in the normal sand storage bin.

[0012] Furthermore, the sandblasting system includes a protective cover, a sandblasting port and a sandblasting gun, wherein the sandblasting port is located at the top of the main box, the protective cover is movably connected to the top of the main box, and the sandblasting gun is located directly below the sandblasting port and is respectively connected to the pneumatic system and the sand storage bin.

[0013] Furthermore, a detection sensor is provided at the connection between the protective cover and the main box body.

[0014] Furthermore, the wire cutting oil spray assembly includes a sub-tank body, which is installed on one side of the top of the main tank body, and the top of the sub-tank body is provided with a wire cutting oil spray port, and the sub-tank body is provided with an anti-splash liquid storage box and a waste storage bin, and a wire cutting oil spray drive assembly is provided directly below the wire cutting oil spray port.

[0015] Furthermore, the wire cutting oil injection drive assembly includes a wire cutting cylinder seat, a wire cutting blade assembly and a double-force wire cutting cylinder, and oil injection pipes and nozzles are arranged on both sides of the wire cutting cylinder seat. The driving end of the double-force wire cutting cylinder is connected to the wire cutting blade assembly, and the wire cutting blade assembly is installed on the wire cutting cylinder seat.

[0017] Furthermore, a circuit box is also arranged outside the main box.

[0018] Furthermore, a mounting base plate is provided at the bottom of the main box.

[0019] Compared with the prior art, the robot welding gun sandblasting cleaning station provided by the utility model has the following beneficial effects:

[0020] In the utility model, a robot welding gun sandblasting gun cleaning station arranges the solenoid valve assembly on the outside of the main box body to reduce the volume of the main box body. The recovery system also adopts an aerodynamic filter. Compared with the vibrating screen separator of the existing sandblasting gun cleaning station, it has a smaller volume and can also avoid excessive noise.

[0021] The wire cutting oil spraying assembly in the utility model has the functions of wire cutting and oil spraying. Oil spray pipes and nozzles are arranged on both sides of the wire cutting cylinder seat.

The welding wire is directly placed in the middle of the wire cutting blade combination to wait for cutting. This not only optimizes the overall structure and reduces the failure rate, but also improves the working rhythm. BRIEF DESCRIPTION OF THE DRAWINGS
