[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] like Figure 1-5As shown, the present application provides a coating device for copper foil surface coating, comprising: a coating box 1, a feeding support mechanism 2 and a cleaning mechanism 3. Rectangular holes connected to the coating box 1 are opened on both sides, and a spraying mechanism 4 is installed inside the coating box 1. The feeding support mechanism 2 comprises a pair of support arms 21 installed on one side of the coating box 1, and the support arms 21 are fixed to one side of the coating box 1 by welding. A second rotating roller 23 is rotatably connected between the pair of support arms 21, and a first rotating roller 22 is rotatably connected between the pair of support arms 21. The height of the first rotating roller 22 is higher than the height of the second rotating roller 23. The first rotating roller 22 and the second rotating roller 23 are provided to provide support for the copper foil. Their main function is to guide and stabilize the conveying path of the copper foil to ensure that the copper foil remains straight during the coating process. The cleaning mechanism 3 is located inside the coating box 1. The cleaning mechanism 3 comprises a mounting frame 31, and a pair of cleaning cottons 32 are installed on the inner wall of the mounting frame 31; wherein, the second rotating roller 23 can drive the mounting frame 31 to reciprocate in the horizontal direction during rotation.

[0030] In this embodiment, the present solution is a device for coating the surface of copper foil during its production process. Its main function is to form a coating with specific functions on the surface of the copper foil. These coatings can give the copper foil new properties, such as improved conductivity, corrosion resistance, oxidation resistance, insulation, and water resistance. Specifically, the copper foil to be coated is sequentially passed through the first rotating roller 22, the second rotating roller 23, and the mounting frame 31, and finally passes through the coating box 1 and extends to the outside of the coating box 1. Finally, the end of the coating box 1 is connected to the external winding mechanism, and the winding mechanism is used to control the copper foil to be transported. At this time, the pressure pump is connected to the spraying mechanism 4 to transport the coating to the spray pipe 41, and the top and bottom of the copper foil are sprayed.

[0031] Among them, the second rotating roller 23 is arranged to abut against the copper foil. During the transportation of the copper foil, the second rotating roller 23 rotates to force the installation frame 31 to move back and forth horizontally in the coating box 1. The cleaning cotton 32 on the inner wall of the installation frame 31 can clean both sides of the copper foil, effectively removing dust, grease, oxides and other dirt on the surface of the copper foil, improving the cleanliness of the copper foil, and improving the subsequent coating effect of the copper foil.

[0032] like Figure 1-5 As shown, a pair of connecting blocks 33 are installed on the outside of the mounting frame 31, and the connecting block 33 is fixed to one side of the connecting block 33 by means of bolts. A pair of slide grooves are provided on the outer wall of the coating box 1, and the connecting block 33 passes through the slide grooves and is slidably connected to the slide grooves. Turntables 24 are installed at both ends of the second rotating roller 23, and the turntable 24 is fixed to the end of the second rotating roller 23 by welding. A connecting rod 25 is rotatably connected to one side of the turntable 24 and away from the center of the circle, and the end of the connecting rod 25 away from the turntable 24 is rotatably connected to the connecting block 33.

[0033] In this embodiment, the second rotating roller 23 is provided to abut against the copper foil. During the copper foil conveying process, the second rotating roller 23 rotates, synchronously driving the turntable 24 at the end to rotate. Under the transmission action of the connecting rod 25, the connecting block 33 is driven to slide back and forth in the slide groove, thereby realizing the horizontal reciprocating movement of the mounting frame 31 in the coating box 1, and then cleaning the surface of the copper foil.

[0034] like Figure 4 As shown, the spraying mechanism 4 includes a plurality of spraying pipes 41, which are installed to the inner wall of the coating box 1, and the plurality of spraying pipes 41 are respectively located above and below the copper foil. The spraying mechanism 4 also includes a connecting main pipe 43, and a connecting branch pipe 42 is installed at one end of the plurality of spraying pipes 41, and the plurality of connecting branch pipes 42 are all connected to the connecting main pipe 43, and a connecting flange 44 is installed at one end of the connecting main pipe 43.

[0035] In this embodiment, an external pressure pump can be connected to the connecting flange 44 to deliver the coating to the spray pipe 41 to spray the top and bottom of the copper foil.

[0036] In this embodiment, a discharge port is provided at the bottom of the coating box 1. The paint dripping during the spraying process can fall to the bottom of the inner cavity of the coating box 1 and finally be discharged to the outside through the discharge port, thereby collecting the paint.

[0037] Working principle:

[0038] The copper foil to be coated is passed through the first rotating roller 22, the second rotating roller 23 and the mounting frame 31 in sequence, and finally passes through the coating box 1 and extends to the outside of the coating box 1. Finally, the end of the coating box 1 is connected to the external winding mechanism, and the winding mechanism is used to control the copper foil to be transported. The second rotating roller 23 is arranged to abut against the copper foil. During the copper foil transportation process, the second rotating roller 23 rotates, synchronously driving the turntable 24 at the end to rotate. Under the transmission action of the connecting rod 25, the connecting block 33 is driven to slide back and forth in the slide groove, thereby realizing the horizontal reciprocating movement of the mounting frame 31 in the coating box 1. The cleaning cotton 32 on the inner wall of 31 can clean both sides of the copper foil and effectively remove dust, grease, oxides and other dirt on the surface of the copper foil. The cleaned copper foil continues to be transported forward and enters the spraying area. By connecting the pressure pump to the spraying mechanism 4, the paint is transported to the spraying pipe 41, and the top and bottom of the copper foil are sprayed to form a uniform coating with specific functions. These coatings can give the copper foil new properties according to needs, such as improving conductivity, corrosion resistance, oxidation resistance, insulation, waterproofness, etc. After coating, the copper foil continues to be transported forward to the outside of the coating box 1 for subsequent drying operations.

[0039] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
