[0002] Polyimide film silicone tape is a specially treated high-temperature resistant insulating material. It is mainly composed of polyimide film as the substrate and coated with high-temperature resistant silicone. In the coating process, a coating device is required to coat and laminate the polyimide film and silicone. However, in the coating and curing process of polyimide film silicone tape, changes in the temperature and humidity of the external environment can easily affect the high-temperature curing effect of PO silicone tape. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a high-temperature curing coating device for polyimide film silicone tape is provided to solve the problem that changes in temperature and humidity of the external environment can easily affect the high-temperature curing effect of PO silicone tape during the coating and curing process.

[0004] To achieve the above objectives, a high-temperature curing coating apparatus for polyimide film silicone tape is provided, comprising: a coating machine body, wherein a coating protective cover is fixedly attached to the upper end of the coating machine body.

[0005] The coating protective cover is equipped with a coating roller and a guide roller on its inner side. The side end of the coating roller is connected to a first electric actuator through a frame one, and the side end of the guide roller is connected to a second electric actuator through a frame two. A nozzle is installed on the upper end face of the guide roller. A curing dust cover is welded to the right end of the coating protective cover. An exhaust port and an air inlet are provided on the inner side of the curing dust cover. A hot air circulation box is fixed on the upper surface of the curing dust cover. A water-absorbing resin mesh plate and an activated carbon mesh plate are sealed and inserted into the middle of the inner side of the hot air circulation box. A U-shaped partition is inserted into the outer side of the water-absorbing resin mesh plate and the activated carbon mesh plate. A heater is installed on the inner wall of the hot air circulation box.

[0006] Furthermore, a conveyor belt is installed on the inner side of the upper end of the coating machine body, and a windproof curtain is installed on the lower end face of the coating protective cover; and the lower end of the windproof curtain is in contact with the conveyor belt.

[0007] Furthermore, a silicone tube is fixed to the upper end of the coating protective cover, and the rear side of the silicone tube is connected to the nozzle through a pipe. Coating rollers are distributed at the lower end of the guide roller.

[0008] Furthermore, the coating roller and the guide roller are axially connected to the front and rear sides of the frame one and the frame two; and displacement sensors are embedded in the lower end faces of both the frame one and the frame two.

[0009] Furthermore, the first electric actuator and the second electric actuator are respectively embedded and fixed in the inner wall of the upper end and the inner walls of the left and right sides of the coating protective cover.

[0010] Furthermore, the left end of the heat circulation air box is connected to the air inlet through an exhaust pipe, and a delivery pump is installed on the surface of the exhaust pipe.

Detailed Implementation

[0018] Reference Figures 1 to 4 As shown, this utility model provides a high-temperature curing coating device for polyimide film silicone tape, including: a coating machine body 1, and a coating protective cover 22 fixedly attached to the upper end of the coating machine body 1.

[0019] The coating protective cover 22 is equipped with a coating roller 2 and a guide roller 21 on its inner side. The side end of the coating roller 2 is connected to a first electric push rod 26 through a frame 25. The side end of the guide roller 21 is connected to a second electric push rod 28 through a frame 27. A nozzle 23 is installed on the upper end of the guide roller 21. A curing dust cover 5 is welded to the right end of the coating protective cover 22. An exhaust port 51 and an air inlet 52 are provided on the inner side of the curing dust cover 5. A hot air circulation box 4 is fixed on the upper surface of the curing dust cover 5. A water-absorbing resin mesh plate 43 and an activated carbon mesh plate 44 are sealed and inserted in the middle of the inner side of the hot air circulation box 4. A U-shaped partition plate 48 is inserted on the outer side of the water-absorbing resin mesh plate 43 and the activated carbon mesh plate 44. A heater 45 is installed on the inner wall of the hot air circulation box 4.

[0020] First, the coating machine 1 conveys the polyimide film via conveyor belt 11 to the coating roller 2 inside the coating protective cover 22. The nozzle 23 sprays adhesive onto the guide roller 21, which in turn evenly coats the surface of the coating roller 2 with silicone. As the coating roller 2 rotates, the silicone is then coated onto the polyimide film, thus laminating the polyimide film and silicone. After coating, the film is conveyed to the curing dust cover 5. Through the exhaust vent 51 inside the curing dust cover 5, the gas, heated and dehumidified by the hot air circulation box 4, is exhausted onto the coated polyimide film and silicone surface, accelerating the coating process with high-temperature hot air. During curing, the gas discharged from the exhaust vent 51 flows to the air inlet 52 and is drawn into the hot air circulation box 4. The temperature and humidity monitor detects whether the gas needs to be heated or dehumidified. If so, the heater 45 heats at a constant temperature, and the U-shaped partition 48 moves backward to allow the airflow to pass through the water-absorbing resin mesh plate 43 and the activated carbon mesh plate 44. The heated and dehumidified gas is then discharged into the curing dust cover 5, which facilitates the high-temperature curing of the coated polyimide film silicone tape under stable temperature and humidity. This effectively avoids the influence of external environmental factors on the curing speed and effect of the polyimide film silicone tape, ensuring that the polyimide film and silicone can be firmly coated and bonded together.

[0021] In this embodiment, a conveyor belt 11 is installed on the inner side of the upper end of the coating machine body 1, and a windproof curtain 24 is installed on the lower end face of the coating protective cover 22; and the lower end of the windproof curtain 24 is in contact with the conveyor belt 11.

[0022] In a preferred embodiment, the conveyor belt 11 facilitates the transport of the polyimide film silicone tape being processed to the coating and curing mechanisms for continuous coating processing. The windbreak curtain 24 helps to prevent outside air from entering the enclosure.

[0023] In this embodiment, a silicone tube 3 is fixed to the upper end of the coating protective cover 22, and the rear side of the silicone tube 3 is connected to the nozzle 23 through a pipe. A coating roller 2 is distributed at the lower end of the guide roller 21. A frame 1 25 and a frame 27 are axially connected to the front and rear sides of the coating roller 2 and the guide roller 21; and displacement sensors are embedded in the lower end faces of both the frame 1 25 and the frame 27. The first electric push rod 26 and the second electric push rod 28 are respectively embedded and fixed in the inner wall of the upper end and the inner walls of the left and right sides of the coating protective cover 22.

[0024] In a preferred embodiment, the silicone cartridge 3 stores silicone that is composited with the polyimide film. The silicone is sprayed onto the surface of the guide roller 21 through the nozzle 23. The silicone on the surface of the guide roller 21 is then rotated and evenly coated onto the coating roller 2, so that the coating roller 2 can evenly coat the silicone onto the surface of the polyimide film. The coating thickness can be adjusted by adjusting the distance between the guide roller 21 and the coating roller 2.

[0025] In this embodiment, the left end of the heat circulation air box 4 is connected to the air inlet 52 via an exhaust pipe 46, and a delivery pump 47 is installed on the surface of the exhaust pipe 46. The right end of the heat circulation air box 4 is connected to the exhaust outlet 51 via an air supply pipe 42, and a temperature and humidity monitor 41 is embedded in the inner wall of the upper end of the heat circulation air box 4.

[0026] In a preferred embodiment, the delivery pump 47 draws the gas discharged from the exhaust port 51 into the hot air circulation box 4 when it flows to the air inlet 52. The gas entering the hot air circulation box 4 is monitored for temperature and humidity by the temperature and humidity monitor 41. When the humidity is too high, the U-shaped partition 48 (the rear end of the U-shaped partition 48 is connected to the hot air circulation box 4 via a hydraulic rod) moves backward, so that the water-absorbing resin mesh plate 43 and the activated carbon mesh plate 44 come into contact with the air inside the box. The gas inside the box is dehumidified and adsorbed before being discharged back to the exhaust port 51 of the curing dust cover 5. This allows the coated polyimide film silicone tape to be cured at high temperature under stable temperature and humidity, effectively avoiding the influence of external environmental factors on the curing speed and effect of the polyimide film silicone tape.

[0027] This invention relates to a high-temperature curing coating device for polyimide film silicone tape. This device effectively solves the problem that changes in temperature and humidity in the external environment can easily affect the high-temperature curing effect of PI silicone tape during the coating and curing process. It facilitates high-temperature curing of the coated polyimide film silicone tape under stable temperature and humidity conditions, effectively avoiding the influence of external environmental factors on the curing speed and effect of the polyimide film silicone tape. This ensures that the polyimide film and silicone can be firmly coated and bonded, improving the processing efficiency of the high-temperature curing coating device. It is suitable for high-temperature curing coating devices for polyimide film silicone tape.
