Description

Technical Field

[0001] This utility model relates to the field of copper foil production technology, and specifically to a copper foil surface treatment mechanism. Background Technology

[0002] Copper foil is a very thin sheet of copper, typically ranging from a few micrometers to tens of micrometers thick. It is widely used in the electronics industry, particularly as a conductive layer in the manufacture of printed circuit boards (PCBs). Copper foil not only possesses excellent electrical conductivity but can also be etched with complex circuit patterns.

[0003] Copper foil requires anti-oxidation treatment during production because copper readily reacts with oxygen in the air to form copper oxide. This not only affects the appearance of the copper foil but may also affect its conductivity. To prevent this, the copper foil is usually immersed in a specific chemical solution to form a protective film on its surface, thereby slowing down or preventing the reaction between copper and oxygen in the air. However, after immersing the copper foil in the chemical solution, some residual liquid will adhere to the surface of the copper foil. If this residual liquid is not removed, the internal quality of the copper foil will be reduced when it is directly wound up. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] To address the technical problem that residual liquid on the surface of lithium copper foil after anti-oxidation treatment can affect its intrinsic quality, this invention provides a copper foil surface treatment mechanism that can effectively remove residual liquid from the copper foil surface.

[0024] Please see Figures 1-4 , Figures 1-4According to one embodiment of the present invention, a copper foil surface treatment mechanism includes a liquid storage tank 1, in which at least one pressure roller 11 is rotatably disposed. The liquid storage tank 1 contains an anti-oxidation liquid, and the liquid level of the anti-oxidation liquid is located above the pressure roller 11. It also includes a liquid removal unit 2 and a drying unit 3 sequentially disposed on the copper foil transport path. The liquid removal unit 2 is located above the liquid storage tank 1 and is used to scrape off residual liquid from the copper foil. The drying unit 3 is located on one side of the liquid storage tank 1 and includes a cover 31, a buffer rack 32, and a hot air component 33. The hot air component 33 is connected to the cover 31 and is used to deliver hot airflow into the cover 31. The buffer rack 32 is located inside the cover 31 and has a curved channel for extending the copper foil transport path. The curved channel is connected to through holes on opposite sides of the cover.

[0025] In this specific embodiment, two pressure rollers 11 are rotatably installed inside the storage tank 1. When the copper foil is transported in the storage tank 1, it can come into contact with the anti-oxidation liquid in the storage tank 1, effectively improving the anti-oxidation effect of the copper foil.

[0026] It should be noted that the liquid removal unit 2 is not limited to a specific structure. As long as it can scrape off the excess anti-oxidation liquid from both surfaces of the copper foil, no further details will be provided here.

[0027] In this specific embodiment, the liquid removal unit 2 includes a mounting frame 21, a first scraper 22, a second scraper 23, and an adjusting member 24. The mounting frame 21 is fixedly connected to the liquid storage tank 1. The first scraper 22 is fixedly connected to the mounting frame 21. The second scraper 23 is slidably connected to the mounting frame 21. A liquid removal gap is formed between the first scraper 22 and the second scraper 23. The adjusting member 24 is disposed on the mounting frame 21 and connected to the second scraper 23. The adjusting member 24 is used to drive the second scraper 23 to move relative to the first scraper 22.

[0028] The mounting frame 21 includes two side plates and a top plate connected between the two side plates. The two side plates are fixedly connected to the opposite sides of the liquid storage tank 1. The first scraper 22 is fixed between the two side plates, and the second scraper 23 is slidably disposed between the two side plates. When the copper foil is inserted into the liquid removal gap, the first scraper 22 and the second scraper 23 can contact the two sides of the copper foil respectively.

[0029] In this specific embodiment, the adjusting member 24 includes a horizontal plate 241, a threaded screw 242, and a handle 243. The horizontal plate 241 is fixedly disposed in the mounting bracket 21. The threaded screw 242 is threadedly rotatably connected to the horizontal plate 241, and one end of the threaded screw 242 is rotatably connected to the second scraper 23. The other end of the threaded screw 242 is fixedly connected to the handle 243.

[0030] Specifically, the horizontal plate 241 is fixed between the two side plates. By rotating the threaded screw 242, the second scraper 23 is driven to slide, which can adjust the width of the liquid removal gap and ensure that the first scraper 22 and the second scraper 23 are in contact with the two sides of the copper foil respectively.

[0031] Based on the above scheme, both the first scraper 22 and the second scraper 23 are provided with a rubber layer; the rubber layer is relatively soft and can effectively prevent the first scraper 22 and the second scraper 23 from damaging the surface of the copper foil.

[0032] Based on the above scheme, in order to ensure the smooth transmission of copper foil, specifically, a redirecting roller 25 is also rotatably arranged inside the mounting frame 21. The redirecting roller 25 is located above the liquid removal gap. After the copper foil passes through the liquid removal gap, it bypasses the redirecting roller 25 and is transmitted to the curved channel.

[0033] It should be noted that through holes are provided on both sides of the cover 31. The copper foil can be inserted into the cover through one through hole and exited from the cover 31 through another through hole. Specifically, the hot air component 33 consists of multiple hot air blowers fixed on the cover 31.

[0034] In this specific embodiment, the buffer rack 32 includes a frame 321, a first buffer component 322 and a second buffer component 323. The first buffer component 322 and the second buffer component 323 are both movably disposed within the frame 321, and the first buffer component 322 is located above the second buffer component 323. The curved channel is formed between the first buffer component 322 and the second buffer component 323.

[0035] It should be noted that, in order to adjust the length of the curved channel and extend the drying time of the copper foil inside the cover, the buffer rack 32 specifically includes a transmission component 324 and a telescopic component 325. The opposite sides of the first buffer component 322 and the second buffer component 323 are connected via the transmission component 324. The telescopic component 325 is located at the bottom of the rack 321 and connected to the second buffer component 323. The telescopic component 325 is used to drive the first buffer component 322 and the second buffer component 323 to move closer or further apart.

[0036] In this specific embodiment, the transmission component 324 includes a shaft 3241, a sprocket 3242, and a chain 3243. The shaft 3241 is fixed to the top of the frame 321, and at least one sprocket 3242 is rotatably mounted on the shaft 3241. One end of the chain 3243 is connected to the first buffer component 322, and the other end of the chain 3243 is connected to the second buffer component 323. The chain 3243 meshes with the sprocket 3242.

[0037] The first buffer 322 includes a first frame 3221 and a plurality of first guide rollers 3222 spaced apart on one side of the first frame 3221; the second buffer 323 includes a second frame 3231 and a plurality of second guide rollers 3232 spaced apart on one side of the second frame 3231; one end of the chain 3243 is connected to the first frame 3221 and the other end of the chain 3243 is connected to the second frame 3231; the curved channel is formed between the plurality of second guide rollers 3232 and the plurality of first guide rollers 3222.

[0038] It should be noted that multiple second guide rollers 3232 and multiple first guide rollers 3222 are arranged alternately to form a continuous S-shaped curved channel. When the copper foil conveying speed remains constant, the longer the length of the S-shaped curved channel, the longer the copper foil can be dried inside the cover.

[0039] In this specific embodiment, the telescopic component 325 consists of two electric push rods, which are respectively fixed to the bottom of the frame. The telescopic ends of both electric push rods are connected to the second frame 3231. When the two electric push rods push the second frame 3231 to rise, they can drive the first frame 3221 to fall, thereby shortening the length of the curved channel. When the two electric push rods pull the second frame 3231 to fall, they can drive the first frame 3221 to rise, thereby extending the length of the curved channel. Of course, in other embodiments, the telescopic component 325 can also be a pneumatic cylinder or a hydraulic cylinder.

[0040] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
