[0002] Copper-aluminum composite plates are a kind of composite material that combines the advantages of copper and aluminum, and are usually used in occasions where good electrical conductivity and corrosion resistance are required. In order to further enhance their performance or endow them with specific functions, surface treatment and coating of copper-aluminum composite plates are very necessary. The coating layer can provide functions such as anti-corrosion protection, improved appearance, and increased wear resistance.

The coating device for the surface of the clad plate of the aluminum-copper explosion welding composite plate further includes: a plurality of sliding columns, all slidably connected to the lower side of the supporting top plate, and a buffer material storage box is commonly connected to the side of the plurality of sliding columns away from the supporting top plate. A plurality of communicating pipes are connected to the lower side of the buffer material storage box. Through the supporting top plate, sliding columns, buffer material storage box, electric telescopic rods, communicating pipes, horizontally arranged feeding pipes, solenoid valves, discharge pipes, C-shaped mounting seats, coating rollers, moving slats and driving components, the utility model can evenly coat the buffer material on the surface of the clad plate in a highly automated coating manner, and the coating uniformity of the buffer material on the surface of the clad plate is high, thus greatly improving the coating efficiency of the buffer material on the clad plate.

[0004] Traditional coating processes often make it difficult to ensure that the coating is evenly distributed on the surface of the workpiece. Especially when using a spray head for spraying, due to the uneven distribution of the sprayed coating particles, it is easy to cause the phenomenon of local over-thickness or under-thickness, affecting the coating quality.

[0005] During the use of the coating roller, it is easy to accumulate too much coating. If not cleaned in time, it will affect the coating effect of subsequent workpieces. Most traditional cleaning methods require manual cleaning of the coating roller, which is time-consuming and laborious. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a surface treatment and coating device for copper-aluminum composite plates, which can avoid the situation that when spraying with a spray head, due to the uneven distribution of the sprayed coating particles, it is easy to cause the phenomenon of local over-thickness or under-thickness, affecting the coating quality.

[0025] The following will, with reference to the drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0026] Please refer to Figures 1 to 5 , the embodiment of the present utility model provides a copper-aluminum composite plate surface treatment coating device, including a coating rack 1. A top plate 6 is provided at the upper end of the coating rack 1. Slide holes are opened on both sides of the top plate 6. Two moving rods 8 are respectively slidably connected in the two slide holes. The lower end of the moving rod 8 is connected with a slide rail 9. A connecting plate 10 is slidably arranged in the slide rail 9. The lower ends of the two connecting plates 10 are provided with a coating assembly.

[0027] Among them, the coating assembly includes a coating roller 11 rotatably arranged between the two connecting plates 10. The coating roller 11 is driven by a motor. When the coating roller 11 rotates, the uniformity of the paint coating can be improved.

[0028] To spray the workpiece, a spray pipe 13 is installed on one side of the connecting plate 10. A plurality of nozzles 14 are arranged on the lower side of the spray pipe 13. And a paint cylinder 19 is installed on one side of the coating rack 1. The discharge port of the paint cylinder 19 is connected to the feed port of the delivery pump 20 through a pipeline. The discharge port of the delivery pump 20 and the feed port of the spray pipe 13 are connected through a pipeline, and the pipeline passes through the through groove 7 opened on the top plate 6. The pipeline has a certain length to meet the moving spraying of the spray pipe 13.

[0029] As Figure 1 shown, the second lead screw 18 rotatably arranged in one of the sliding holes is threadedly connected to the moving rod 8. The second lead screw 18 is driven by a motor. When the second lead screw 18 rotates, the moving rod 8 can drive the spray pipe 13 to achieve moving spraying. At the same time, the coating roller 11 coats the paint sprayed by the nozzles 14.

[0030] Furthermore, a scraper 15 is arranged on one side of the connecting plate 10. The scraper 15 is inclined and fits against one side of the coating roller 11. The scraper 15 comes into contact with the paint prior to the coating roller 11 and scrapes the paint first, improving the uniformity of paint coating.

[0031] And the scraper 15 can scrape the paint on the coating roller 11. When the coating roller 11 rotates in the air, the scraper 15 can be used to clean the coating roller 11 to prevent the paint from drying on the coating roller 11.

[0032] One end of the rotating shaft of the scraper 15 penetrates through the connecting plate 10 and is connected to the knob 16. The knob 16 is fixed by the positioning rod 17, which can improve the stability of the scraper 15.

[0033] A cylinder 12 is installed inside the slide rail 9. The piston end of the cylinder 12 is connected to the upper end of the connecting plate 10. When the coating roller 11 moves back, the connecting plate 10 is lifted upward by the cylinder 12, so that the coating roller 11 is kept away from the workpiece to avoid scratching the paint.

[0034] To facilitate the coating of the workpiece, sliding grooves 2 are symmetrically opened on the lower side of the coating rack 1. The first lead screws 3 are rotatably arranged in the two sliding grooves 2 respectively. The two first lead screws 3 are connected by a transmission member 4. And a feeding plate 5 is slidably connected in the sliding groove 2. The feeding plate 5 is threadedly connected to the first lead screw 3. The transmission member 4 is driven by a motor. The transmission member 4 is two belt pulleys respectively connected to the first lead screws 3 and a belt sleeved on the two belt pulleys. When the transmission member 4 operates, it causes the two first lead screws 3 to rotate, so that the feeding plate 5 slides in the sliding groove 2. The workpiece can be placed on the feeding plate 5 and is lifted and lowered by the sliding of the feeding plate 5, facilitating the picking and placing of the workpiece and reducing the labor intensity of the staff at the same time.

[0035] In summary, for the surface treatment and coating equipment of a copper-aluminum composite plate in an embodiment of the present utility model, the working principle is as follows: Place the workpiece on the feeding plate 5. Through the rotation of the first lead screw 3, the feeding plate 5 drives the workpiece to move to the upper end of the coating rack 1. The transfer pump 20 transports the coating material into the spraying pipe 13, and it is sprayed onto the workpiece by the spray head 14. At the same time, by the rotation of the second lead screw 18, the moving rod 8 drives the connecting plate 10 to move, thus not only realizing moving spraying, but also the squeegee 15 can evenly spread the coating material, and the coating roller 11 can coat the coating material. After the coating is completed, move the coating roller 11 to one side of the coating rack 1, and drive the coating roller 11 to rotate through the motor, so that the squeegee 15 scrapes the coating material on the coating roller 11 to prevent the coating material from drying up.

[0036] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
