[0002] Coating is an important part of surface manufacturing processes. Rust prevention, corrosion prevention, aesthetics, and mitigating the inherent defects of the material are all important aspects of coating quality, which are crucial to the overall quality of the product. When processing robot shells, the surface needs to be pre-treated before spraying, and then allowed to dry. Placing the shell inside the spray booth during spraying avoids paint spilling onto the ground. However, paint will still be sprayed onto the inner wall of the spray booth during spraying, which is inconvenient to clean. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a simple, rationally designed, and easy-to-use coating machine for processing robot shells that is easy to clean.

[0068] Example 3:

[0069] Please see Figures 1-6 Based on Embodiment 1, a further improvement is made, wherein the rotating assembly 17 comprises:

[0070] Support shaft 17-1 is fixed to the bottom right side of support base block 15, and the bottom end of support shaft 17-1 is screwed into connecting support block 14 via bearing;

[0071] The fixing ring 17-2 is sleeved on the support shaft 17-1 and fixed to the connecting support block 14.

[0072] The fixing frame 17-3 is fixed to the connecting support block 14 and is located on the front side of the fixing ring 17-2.

[0073] The rotating motor 17-4 is fixed to one side of the fixed frame 17-3 and is connected to an external power source. The specific model of the rotating motor 17-4 is purchased and installed directly from the market according to actual usage requirements. After the output shaft of the rotating motor 17-4 passes through the side wall of the fixed frame 17-3, a double-acting lead screw 17-5 is fixed thereon, and the other end of the double-acting lead screw 17-5 is screwed to the other side wall of the fixed frame 17-3 through a bearing.

[0074] The movable block 17-6 consists of two blocks, which are respectively threaded onto two opposite threads on the bidirectional lead screw 17-5; and the front side of the movable block 17-6 is in contact with the inner wall of the fixed frame 17-3.

There are four positioning holes 17-1-1, which are evenly distributed around the circumference.

[0076] Through the above technical solution design, the rotation of the bidirectional lead screw 17-5 causes the two moving blocks 17-6 to move synchronously, which in turn causes the insertion rod 17-7 to move and insert into the support shaft 17-1, thereby strengthening the stability of the support shaft 17-1.

[0077] When using this invention, the robot shell is placed on the support platform 7, and the spray head 2 is operated by the spray driving component 5 to spray the shell. During the spraying process, the part of the shell exposed on the support platform 7 is prone to spraying paint and dripping into the support ring 8. Before spraying, the cylinder 13 drives the cleaning brush component 11 away from the support ring 8 and away from the spray box 1. The support base block 15 is manually rotated so that it rotates 90° around the screw joint at the bottom of the support shaft 17-1. The rotating motor 17-4 is started to rotate the bidirectional lead screw 17-5, which drives the moving blocks 17-6 on both sides to move towards the center, so that the insertion rod 17-7 is inserted into the support shaft 17-1, and the support base block 15 is in a fixed state. Then the spraying operation can be carried out.

[0078] After spraying, the rotating component 17 is used again to start the rotating motor 17-4, which moves the two moving blocks 17-6 outward, moving the insert rod 17-7 away from the inside of the support shaft 17-1. The support base block 15 is rotated so that the support frame 10 is placed in the spray box 1. Then, the two moving blocks 17-6 are moved inward so that the insert rod 17-7 is inserted into the support shaft 17-1, positioning the support shaft 17-1. The cylinder 13 drives the support frame 10 to move downward until the cleaning brush component 11 is placed inside the support ring 8 and fits against the support ring 8. Water is injected into the support ring 8, and the rotating motor 16 is started so that the support frame 10 drives the outer roller brush 11-3, the inner roller brush 11-4, and the brush block 11-6 to rotate inside the support ring 8, completing the cleaning. The wastewater after cleaning flows down from the discharge trough 8-1 into the drainage ring 9. The wastewater is discharged by connecting the water pipe to the drainage trough 9-1.

[0079] After a period of use, the outer roller brush 11-3, the inner roller brush 11-4, and the brush block 11-6 can all be cleaned. The outer roller brush 11-3 and the inner roller brush 11-4 are installed and disassembled by the engagement of the threaded post 11-10 and the nut.

[0080] After adopting the above structure, the beneficial effects of this specific embodiment are as follows:

[0081] 1. The cleaning brush assembly 11 can be positioned to avoid interference between spraying and cleaning operations;

[0082] 2. The outer roller brush 11-3, the inner roller brush 11-4, and the brush block 11-6 can all be disassembled for easy cleaning of the brush bristles;

[0083] 3. Four opposing positioning holes 17-1-1 are provided on the outside of the support shaft 17-1, which can be used to position the support shaft 17-1 by inserting the rod 17-7, and facilitate the rotation of the support block 15.

[0084] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
