Description

Technical Field

[0001] This utility model relates to the field of battery film technology, and in particular to a cleaning device for battery film production. Background Technology

[0002] Cleaning equipment for battery membrane production is a specialized industrial tool used in the lithium battery manufacturing process. Its main function is to efficiently clean the battery separator. This equipment typically uses a combination of physical cleaning and high-pressure spraying to remove contaminants such as dust, oil, and metal particles that adhere to the separator surface during production, slitting, and transportation. This ensures the cleanliness and unobstructed pores of the separator, thereby preventing safety hazards such as internal short circuits, self-discharge, or thermal runaway caused by impurities. It is a crucial production step for improving the consistency, safety, and lifespan of lithium batteries. However, existing cleaning equipment for battery membrane production still has limitations, such as the inability to remove dust during the initial cleaning process and the inability to continuously clean the battery membrane.

[0003] Therefore, it is essential to invent a cleaning device for battery film production. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cleaning device for battery film production, solving the issues that existing cleaning devices for battery film production still cannot first remove dust during cleaning and cannot continuously clean the battery film. The cleaning device for battery film production includes a cleaning space, a support frame, a water inlet structure, a dust dispersion structure, a cleaning nozzle, and a battery film. The cleaning space is fixedly installed on the ground via the support frame, and the support frame is fixedly installed on the inner wall of the cleaning space. The water inlet structure is fixedly installed on one side of the support frame. The cleaning nozzle is fixedly installed on the other side of the support frame, and the dust dispersion structure is fixedly installed on the water inlet structure. The battery film passes through the cleaning space.

[0005] The water inlet structure includes a pressure chamber, a water filter, an inlet pipe, a pressurizing pipe, and an outlet. The pressure chamber is fixedly installed on one side of the equipment support via a bracket, and the water filter is fixedly installed at one end of the pressure chamber. The inlet pipe is fixedly installed at one end of the water filter, and the pressurizing pipe is fixedly installed at one end of the pressure chamber. The outlet is fixedly installed below the pressure chamber and connected to the cleaning nozzle.

[0006] The dust collection structure includes a connecting seat, a support body, a power structure, and a dust sweeping roller. The connecting seat is fixedly installed on the water inlet structure, and the support body is fixedly installed on the connecting seat. The power structure is fixedly installed on the support body, and the dust sweeping roller is rotatably installed inside the power structure.

[0007] The pressure chamber inside the water inlet structure is a rectangular steel metal chamber. The pressure chamber can be filled with cleaning water through the inlet pipe and filtered by a water filter. A one-way valve is fixedly installed inside the inlet pipe. Gas can be introduced into the pressure chamber through the pressurization pipe to create a high-pressure state inside the pressure chamber. The high pressure inside the pressure chamber can output the water inside through the outlet and spray it out through the cleaning nozzle connected to the outlet.

[0008] The dust-sweeping roller inside the dust-dispersing structure is a cylindrical structure with fluff, and the dust-sweeping roller can closely adhere to the surface of the battery film and rotate continuously driven by the power structure.

[0009] The equipment support, water inlet structure, dust dispersion structure, and cleaning nozzles are all in pairs and face the upper and lower surfaces of the battery membrane.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The water inlet structure of this utility model stores clean water input through the water inlet pipe and filtered by the water filter in a pressure chamber. Then, gas is injected into the pressure chamber through the pressurization pipe to establish high pressure. Finally, the high-pressure water is stably delivered from the water outlet to the cleaning nozzle, providing the necessary high-pressure clean water flow for efficient rinsing of the battery membrane surface.

[0011] The dust-dispersing structure of this utility model is designed to remove dust and impurities adhering to the surface of the battery film. Its core component, the dust-sweeping roller, rotates continuously under the drive of the power structure, using the bristles on its surface to sweep the surface of the battery film. The support body provides stable support through the connecting seat, ensuring that the sweeping action is tight and effective, providing pretreatment for subsequent high-pressure water cleaning, and improving the overall cleaning effect.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] As attached Figure 1 To be continued Figure 2 As shown.

[0017] This utility model provides a cleaning device for battery film production, including a cleaning space 1, a device support 2, a water inlet structure 3, a dust dispersion structure 4, a cleaning nozzle 5, and a battery film 6. The cleaning space 1 is fixedly installed on the ground via a support, and the device support 2 is fixedly installed on the inner wall of the cleaning space 1. The water inlet structure 3 is fixedly installed on one side of the device support 2 via a support. The cleaning nozzle 5 is fixedly installed on the other side of the device support 2 via a support, and the dust dispersion structure 4 is fixedly installed on the water inlet structure 3. The battery film 6 passes through the cleaning space 1.

[0018] The water inlet structure 3 includes a pressure chamber 31, a water filter 32, an inlet pipe 33, a pressurizing pipe 34, and an outlet 35. The pressure chamber 31 is fixedly installed on one side of the equipment support 2 by a bracket, and the water filter 32 is fixedly installed at one end of the pressure chamber 31. The inlet pipe 33 is fixedly installed at one end of the water filter 32, and the pressurizing pipe 34 is fixedly installed at one end of the pressure chamber 31. The outlet 35 is fixedly installed below the pressure chamber 31 and connected to the cleaning nozzle 5.

[0019] The dust collection structure 4 includes a connecting seat 41, a support body 42, a power structure 43, and a dust sweeping roller 44. The connecting seat 41 is fixedly installed on the water inlet structure 3, and the support body 42 is fixedly installed on the connecting seat 41. The power structure 43 is fixedly installed on the support body 42, and the dust sweeping roller 44 is rotatably installed inside the power structure 43.

[0020] The pressure chamber 31 inside the water inlet structure 3 is a rectangular steel metal chamber. The pressure chamber 31 can be filled with cleaning water through the water inlet pipe 33 and filtered by the water filter 32. A one-way valve is fixedly installed inside the water inlet pipe 33. Gas can be introduced into the pressure chamber 31 through the pressurization pipe 34 to create a high-pressure state inside the pressure chamber 31. The high pressure inside the pressure chamber 31 can output the water inside through the water outlet 35 and spray it out through the cleaning nozzle 5 connected to the water outlet 35.

[0021] The dust-sweeping roller 44 inside the dust-dispersing structure 4 adopts a cylindrical structure with fluff, and the dust-sweeping roller 44 can closely adhere to the surface of the battery film 6 and rotate continuously driven by the power structure 43.

[0022] The equipment support 2, water inlet structure 3, dust dispersion structure 4 and cleaning nozzle 5 are all in pairs and face the upper and lower surfaces of the battery film 6.

[0023] This battery membrane cleaning equipment operates based on the principle of sweeping followed by water washing. As the battery membrane 6 continuously passes through the cleaning space 1, it is first treated by the paired dust-collecting structures 4: its power structure 43 drives the brush-covered dust-collecting rollers 44 to rotate close to the membrane surface, effectively brushing away loose dry dust and particles, providing pretreatment for subsequent cleaning. Next, the high-pressure water washing system is activated: the water inlet structure 3 inputs water through the inlet pipe 33, which is purified by the water filter 32 and stored in the pressure chamber 31. Gas is then injected through the pressurization pipe 34 to establish high pressure, finally delivering clean, high-pressure water from the outlet 35 to the cleaning nozzle 5, which simultaneously and violently sprays the surface of the battery membrane 6 from both the top and bottom, thoroughly removing stubborn stains.

[0024] Throughout the cleaning process, the equipment support frame 2 provides stable support for each functional module, ensuring accurate and reliable cleaning of the dust-collecting structure 4 and spraying from the cleaning nozzles 5. This combined process removes most loose contaminants through dry sweeping, avoiding secondary stains caused by wastewater mixing, and then completes deep cleaning with high-pressure water jets. The two processes complement each other, ensuring efficient cleaning while also improving water resource utilization efficiency, ultimately meeting the high cleanliness requirements for the production of the battery membrane 6.

[0025] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
