The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0038] The inventors of the present application have considered that residual glue at the bottom of the sled 2 and paint accumulation on the support block affect the passability of the sled 2 in the spray room and various key positions, often causing equipment shutdowns and line stoppages such as the sled being stuck or the proximity switch being damaged.

[0039] The skid cleaning device provided in the present application is intended to solve the above technical problems in the prior art.

[0040] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0041] like Figure 1 , 2 As shown in Figures 3 and 5, the embodiment of the present application provides a sled cleaning device, which mainly includes a rotatable scraper 1, an elastic reset member 3 and a limit member 4. The rotatable scraper 1 is used to clean the bottom of the sled 2; the elastic reset member 3 is connected to the rotatable scraper 1; the limit member 4 is arranged on one side of the rotatable scraper 1; when the rotatable scraper 1 rotates in the first direction, the rotatable scraper 1 is away from the limit member 4, and the elastic reset member 3 is stretched to accumulate elastic potential energy for the rotatable scraper 1 to reset; when the rotatable scraper 1 rotates in the second direction, the rotatable scraper 1 is close to the limit member 4, and the elastic reset member 3 is stretched to release the accumulated elastic potential energy; the first direction and the second direction are opposite.

[0042] In some embodiments, the sled cleaning device is disposed on a horizontal plane. The rotatable scraper 1 and the sled 2 move relative to each other along the axial direction of the sled 2. The rotatable scraper 1 is disposed below the sled 2 to clean the residual glue and / or accumulated paint (target cleaning object) at the bottom of the sled 2. When the rotatable scraper 1 is in the initial position (i.e., the reset position), it is in close contact with the limit member 4. The rotatable scraper 1 and the limit member 4 are relatively stationary, and the elastic reset member 3 can provide a force for the rotatable scraper 1 to rotate in the second direction. During the stage of the rotatable scraper 1 rotating in the second direction, the elastic reset member 3 stretches to release the accumulated elastic potential energy so that the rotatable scraper 1 is reset.

[0043] Optionally, the first direction is clockwise and the second direction is counterclockwise.

[0044] Optionally, the first direction is counterclockwise and the second direction is clockwise.

[0045] Through the sled cleaning device provided in the embodiment of the present application, when the rotatable scraper 1 contacts the residual glue and / or accumulated paint at the bottom of the sled 2, due to the relative movement of the rotatable scraper 1 and the sled 2 along the sled 2, the residual glue and / or accumulated paint provide a "thrust" to "push" the rotatable scraper 1 to rotate along the first direction, thereby achieving soft contact between the rotatable scraper 1 and the sled 2 to avoid jamming. At the same time, the elastic reset member 3 provides sufficient pulling force, so that the rotatable scraper 1 can quickly return to the appropriate cleaning position and maintain an appropriate cleaning force to ensure the cleaning effect of the rotatable scraper 1.

[0046] like Figure 1 As shown, as an optional embodiment, the rotatable scraper 1 includes a scraping portion 11 and a rotating portion 12. The scraping portion 11 has a convex portion, which is used to contact the target cleaning object at the bottom of the sled 2; the rotating portion 12 is connected to the scraping portion 11 and the elastic reset member 3, and the rotating portion 12 abuts against the limit member 4 when in the reset position.
