Description

Technical Field

[0001] This utility model relates to the field of thermally conductive polyimide film production and processing, specifically to a cleaning device for thermally conductive polyimide film production and processing. Background Technology

[0002] Polyimide film (PI film) is a polymer compound containing imide rings, possessing excellent properties such as high temperature resistance, low temperature resistance, chemical corrosion resistance, high mechanical strength, and good electrical insulation. During production, polyimide film requires a cleaning step to remove surface impurities and contaminants, ensuring film quality and performance. A search revealed existing technology (publication number: CN201821757933.5) for a cleaning device for processing black polyimide film. The description states that "first, the film to be cleaned is placed on the workbench, the valve is opened, and the mixed liquid flows out from the valve driven by a water pump, spraying onto the film surface. A rotating disc drives multiple sets of brushes to rotate, cleaning the film and improving work efficiency." However, in this existing technology, the mixed liquid sprayed from the pipe is not promptly removed, which can easily lead to the polyimide film absorbing moisture, affecting production quality. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a cleaning device for the production and processing of thermally conductive polyimide films is provided to solve the problem that if the mixed liquid sprayed from the pipeline is not removed in time, the polyimide film will absorb moisture and affect the production and processing quality.

[0004] To achieve the above objectives, a cleaning device for the production and processing of thermally conductive polyimide films is provided, comprising: a PI film cleaning machine body and an immersion tank, wherein the immersion tank is disposed on the inner side of the PI film cleaning machine body.

[0005] A rinsing tank is provided at the right end of the soaking tank. A membrane rinsing plate frame is installed on the inner side wall of the rinsing tank. A high-pressure hot water pipe is connected to the upper end face of the membrane rinsing plate frame. A water outlet hole is opened on the lower surface of the membrane rinsing plate frame. A membrane roller is symmetrically connected to the left and right sides of the membrane rinsing plate frame. A spray plate frame is fixed directly below the membrane rinsing plate frame. Spray holes are provided on the upper surface of the spray plate frame. The PI membrane cleaning machine body is connected to two sets of conveyor belts through a motor transmission mechanism. A first absorbent cotton strip and a second absorbent cotton strip are respectively adhered to the outer surface of the conveyor belts.

[0006] Furthermore, a feeding roller is installed on the left side of the upper end face of the PI film cleaning machine body, and a water storage tank is opened inside the PI film cleaning machine body; and the water storage tank surrounds the outer end of the soaking pool.

[0007] Furthermore, a drain outlet is provided on the left end face of the PI membrane cleaning machine body; and the drain outlet is connected to the water storage tank. A viewing window is provided on the front surface of the PI membrane cleaning machine body; and the viewing window is located on the front side of the membrane rinsing plate frame.

[0008] Furthermore, a drain pipe is connected to the left side of the soaking pool, and a cleaning cloth is connected to the rear wall of the soaking pool via a fixing plate. Silicone scrapers are symmetrically inserted into the upper end of the cleaning cloth.

[0009] Furthermore, a transfer roller is installed inside the soaking pool, and the left side of the rinsing pool is connected to the water storage tank through a connecting slot.

[0010] Furthermore, the inner side of the guide membrane flushing plate frame is provided with a liquid inlet chamber, and the high-pressure hot water pipe is connected to the water outlet through the liquid inlet chamber.

[0011] Furthermore, the first and second absorbent cotton strips are symmetrically distributed vertically and located at the right end of the guide membrane rinsing plate frame. Arc-shaped extrusion plates are installed at the left end of the first and the right end of the second absorbent cotton strips.

[0012] The beneficial effects of this utility model are as follows: the cleaning device for the production and processing of thermally conductive polyimide film utilizes the guide film rinsing plate and spray plate in the rinsing tank to clean the upper and lower surfaces of the polyimide film at the lowest point in the rinsing tank. The first and second absorbent cotton strips on the conveyor belt surface absorb water and wipe the surface of the rinsed polyimide film, effectively reducing the time that water stays on the surface of the polyimide film, facilitating the quick drying of the surface of the cleaned polyimide film, avoiding excessive water absorption during the cleaning of the thermally conductive polyimide film, and ensuring the production and processing quality of the thermally conductive polyimide film.

[0020] First, the thermally conductive polyimide film enters the soaking tank 4 of the PI film cleaning machine 1. After soaking, it moves upward from the soaking tank 4. During the upward movement, the thermally conductive polyimide film comes into contact with the cleaning cloth 43 and the silicone scraper 42 to wipe the soaked thermally conductive polyimide film and remove impurities from the film surface. Then, it moves along the guide roller 22 of the guide washing plate frame 2 to the water outlet 24, so that the water outlet 24 and the spray hole 31 below rinse the thermally conductive polyimide film passing through here. After rinsing, it enters between the first absorbent cotton strip 5 and the second absorbent cotton strip 51, so that the moving first absorbent cotton strip 5 and the second absorbent cotton strip 51 wipe and absorb the water on the film surface. Then, it can be removed from the PI film cleaning machine 1, completing the cleaning process of the thermally conductive polyimide film.

[0021] In this embodiment, a feed roller 11 is installed on the left side of the upper end face of the PI membrane cleaning machine body 1, and a water storage tank 15 is provided inside the PI membrane cleaning machine body 1; the water storage tank 15 surrounds the outer end of the soaking tank 4.

A viewing window 14 is provided on the front surface of the PI membrane cleaning machine body 1; and the viewing window 14 is located on the front side of the membrane rinsing plate frame 2.

[0022] In a preferred embodiment, the hot water stored in the water tank 15 can accelerate the reaction rate of the organic solvent in the soaking tank 4, allowing impurities on the surface of the thermally conductive polyimide film to soften and detach more quickly after passing through the soaking tank 4, thereby improving the cleaning efficiency of the thermally conductive polyimide film. The viewing window 14 allows observation of the rinsing process of the thermally conductive polyimide film by the membrane rinsing plate 2 and the spray plate 3.

[0023] In this embodiment, a drain pipe 41 is connected to the left end of the soaking tank 4, and a cleaning cloth 43 is connected to the rear wall of the soaking tank 4 via a fixing plate 44.

[0024] In a preferred embodiment, the drain pipe 41 facilitates the discharge and replacement of the organic solvent. The cleaning cloth 43 and the silicone scraper 42 facilitate the wiping of the soaked thermally conductive polyimide film to remove impurities from the film surface and to scrape off the organic solvent adhering to the film surface. The rinsing tank 6 drains the hot water after rinsing into the water storage tank 15.

[0025] In this embodiment, an inlet chamber 23 is provided on the inner side of the membrane flushing plate frame 2, and the high-pressure hot water pipe 21 is connected to the outlet hole 24 through the inlet chamber 23.

[0026] As a preferred embodiment, the rear end of the spray plate frame 3 is also connected to a high-pressure hot water pipe 21, which facilitates the washing plate frame 2 and the spray plate frame 3 to wash the thermally conductive polyimide film between the gaps and remove residual organic solvents on the film surface.

Arc-shaped extrusion plates 52 are installed at the left end of the first absorbent cotton strip 5 and the right end of the second absorbent cotton strip 51.

[0028] In a preferred embodiment, a thermally conductive polyimide film is in contact between the first absorbent swab 5 and the second absorbent swab 51. The conveyor belt 53 drives the first and second absorbent swabs 5 and 51 to absorb water and wipe the upper and lower surfaces of the thermally conductive polyimide film, facilitating the removal of moisture from the surface of the film after rinsing and preventing excessive water absorption during cleaning. The arc-shaped extrusion plate 52 is used to squeeze out the water from the first and second absorbent swabs 5 and 51.

[0029] This utility model provides a cleaning device for the production and processing of thermally conductive polyimide films. It effectively solves the problem in the prior art where the mixed liquid sprayed from the pipeline is not removed in time, which can easily lead to the polyimide film absorbing moisture and affecting the production and processing quality. It effectively reduces the time that water stays on the surface of the polyimide film, making it easier to quickly wipe the moisture off the surface of the polyimide film after cleaning. It avoids excessive water absorption during the cleaning of thermally conductive polyimide films, ensuring the production and processing quality of thermally conductive polyimide films.
