[0104] refer to Figure 4 The anti-splashing agent spraying mechanism 6 is arranged on the side wall of the main shell 1, and the anti-splashing agent spraying mechanism 6 is located on the side of the protective cover 4, and is used to spray the anti-splashing agent on the welding gun after the gun is cleaned by sandblasting.

[0105] In this embodiment, the protective cover 4, the wire cutting mechanism 2 and the anti-splashing agent spraying mechanism 6 are respectively located on one of the three adjacent surfaces of the main shell 1, and the wire cutting mechanism 2 and the anti-splashing agent spraying mechanism 6 are arranged on opposite sides of the protective cover 4, so that the wire cutting mechanism 2, the sandblasting mechanism 3 and the anti-splashing agent spraying mechanism 6 are arranged on the main shell 1 in a clockwise or counterclockwise direction, while optimizing the layout and reducing the volume of the welding gun sandblasting and cleaning station, it is convenient for the welding gun to move clockwise or counterclockwise to the wire cutting mechanism 2, the sandblasting mechanism 3 and the anti-splashing agent spraying mechanism 6 to perform related operations, which is convenient for operation.

[0106] In other embodiments, at least two of the protective cover 4, the wire cutting mechanism 2 and the anti-splashing agent spraying mechanism 6 may be directly arranged on the same side wall of the main shell 1, and the arrangement order of the protective cover 4, the wire cutting mechanism 2 and the anti-splashing agent spraying mechanism 6 can refer to the above.

[0107] In this embodiment, the anti-spatter spraying mechanism 6 includes a liquid sprayer 61 and a liquid reservoir 62. The top of the liquid sprayer 61 is provided with a gun insertion port 611 for inserting a welding gun. The liquid reservoir 62 is provided below the liquid sprayer 61, and the liquid reservoir 62 is used to store the anti-spatter. The liquid sprayer 61 is connected to the liquid reservoir 62, and the liquid sprayer 61 can absorb the anti-spatter in the liquid reservoir 62 and spray the anti-spatter to the welding gun located at the gun insertion port 611.

[0108] The welding gun sandblasting and cleaning station includes a third controller, which is arranged inside the main housing 1 and is electrically connected to the anti-spatter spraying mechanism 6 to control the opening and closing of the anti-spatter spraying mechanism 6. Specifically, the third controller is electrically connected to the liquid sprayer 61.

[0109] The working principle of the above welding gun sandblasting cleaning station is as follows:

[0110] The welding gun is moved to the wire cutting mechanism 2, and the welding gun is inserted into the first wire cutting opening 211 of the first blade 21 and the second wire cutting opening 221 of the second blade 22. The driving member 23 is started by the first controller to drive the second blade 22 to move relative to the first blade 21 to cut the excess welding wire on the welding gun. The cut waste wire falls into the waste wire basket 25, and then the driving member 23 is closed by the first controller.

[0111] Then the welding gun is lifted out of the wire cutting mechanism 2 and moved to the protective cover 4, so that the welding gun extends from the gun entrance into the protective cavity. The control valve on the gas pipe 33 is controlled to open by the second controller, so that the compressed gas enters the sandblasting gun 31 through the gas pipe 33 to increase the pressure inside the sandblasting gun 31, so that the sandblasting gun 31 can absorb the metal sand in the storage part 42 through the delivery pipe 32 and spray the metal sand to the welding gun to achieve the cleaning of the welding gun. In this process, the used metal sand falls onto the filter element 5, and the waste (slag, dust, etc.) is filtered by the filter element 5, so that the waste (slag, dust, etc.) falls into the collection part 43, and the metal sand that meets the gun cleaning conditions will float on the filter element 5 for repeated use. When the sandblasting operation is completed, the control valve is controlled to close by the second controller.

[0112] Then the welding gun is lifted out of the gun entrance and moved to the anti-splash agent spraying mechanism 6, the welding gun is inserted into the liquid sprayer 61 through the gun insertion port 611, and the liquid sprayer 61 is started by the third controller to make the liquid sprayer 61 absorb the anti-splash agent in the liquid reservoir 62 and spray the anti-splash agent to the welding gun located at the gun insertion port 611. After the spraying is completed, the welding gun is lifted out and the liquid sprayer 61 is closed by the third controller, and the gun cleaning is completed.

[0113] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:

[0114] When the welding gun sandblasting and cleaning station of the present application is used to clean the welding gun, the excess welding wire on the welding gun can be cut by the wire cutting mechanism first, and then the metal sand can be sprayed to the welding gun by the sandblasting mechanism. The metal sand sprayed by the sandblasting mechanism can directly act on the part of the welding gun extending into the protective cavity, and the welding gun can be completely deslaged without dead corners, thereby improving the gun cleaning effect. Finally, the anti-splashing agent is sprayed on the welding gun after the sandblasting treatment by the anti-splashing agent spraying mechanism to complete the gun cleaning operation.

[0115] In addition, in the welding gun sandblasting and cleaning station of the present application, by integrating the wire cutting mechanism, the sandblasting mechanism and the anti-splashing agent spraying mechanism into the side wall of the main shell, the structure is compact and the volume of the entire welding gun sandblasting and cleaning station can be reduced.

[0116] The design of the protective cover can protect the sandblasting gun inside it from external influences and extend its normal working time; the protective cover can also prevent metal sand from splashing to the outside and polluting the external environment, and at the same time can collect the metal sand so that the metal sand that meets the conditions can be recycled.

[0117] The filter element is designed to filter out waste from the used metal sand, so that the waste falls below the filter element and the qualified metal sand floats on the upper surface of the filter element for reuse.

[0118] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
