[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a polytetrafluoroethylene glass fiber substrate roll forming and coating device, including an operating table 1, a first fixed bracket 13 fixedly connected to the upper center of the operating table 1, a coating device 14 provided at the lower end of the first fixed bracket 13, a sliding groove 2 fixedly opened at the upper end of the operating table 1, a limiting slide rod 3 fixedly connected to both ends inside the sliding groove 2, an adsorption fixing device 4 slidably connected inside the sliding groove 2, the limiting slide rod 3 slidably sleeved on both sides of the adsorption fixing device 4, a first threaded rod 5 rotatably connected to the center inside the sliding groove 2, a first drive motor 6 fixedly connected to one end of the first threaded rod 5 through a shaft, the first threaded rod 5 threadedly sleeved on the center of the adsorption fixing device 4, and the adsorption fixing device 4 including a first drive motor 6, a negative pressure chamber 7, a negative pressure pump 8, a first storage battery 10, a negative pressure channel 11 and an adsorption plate 12.

[0020] In this embodiment, the substrate is placed at the four upper corners of the adsorption plate 12 for positioning. Then, the negative pressure pump 8 generates negative pressure to adsorb and fix the substrate, facilitating film coating. When the negative pressure pump 8 is turned off, the pressure returns to normal, allowing for detachment. After fixing, the first drive motor 6 drives the first threaded rod 5 to rotate. The first threaded rod 5 rotates with the adsorption fixing device 4, causing the adsorption fixing device 4 to move threadedly, thereby transporting the substrate. This design uses negative pressure adsorption to fix the substrate, which is simple to fix and detach, and avoids damage to the substrate, providing excellent protection.

[0021] Specifically, a negative pressure pump 8 is fixedly connected to one side of the negative pressure chamber 7, and a first storage battery 10 is fixedly connected to the other side of the negative pressure chamber 7. The negative pressure pump 8 is electrically connected to the first storage battery 10 through wires.

[0022] In this embodiment, the first storage battery 10 can provide power to the negative pressure pump 8, so that the negative pressure pump 8 can generate negative pressure, and thus generate negative pressure inside the negative pressure chamber 7.

[0023] Specifically, the upper four corners of the adsorption fixing device 4 are fixedly connected to negative pressure channels 11, and one end of the negative pressure channel 11 is connected to an adsorption plate 12.

[0024] In this embodiment, the negative pressure channels 11 set at the four corners of the upper end of the negative pressure chamber 7 can be used for positioning. When negative pressure is generated inside the negative pressure chamber 7, the placed substrate can be adsorbed and fixed by the adsorption plate 12.

[0025] Specifically, a second fixed bracket 15 is fixedly connected to one side of the upper end of the operating table 1. Limiting grooves 16 are fixedly opened on both sides of the inner wall of the second fixed bracket 15. A drying device 9 is slidably connected inside the limiting grooves 16. A threaded sleeve 18 is fixedly connected to the upper end of the drying device 9. A second drive motor 17 is fixedly connected to the upper end of the second fixed bracket 15. A second threaded rod 19 is fixedly connected to the second drive motor 17 through a shaft. The second threaded rod 19 is threadedly sleeved inside the threaded sleeve 18.

[0026] In this embodiment, the second drive motor 17 can drive the second threaded rod 19 to rotate after the external power is connected. After the second threaded rod 19 rotates, it can rotate with the threaded sleeve 18. The threaded sleeve 18 is fixed at the upper end of the drying device 9. The two sides of the drying device 9 are limited and can only slide, so that the threaded sleeve 18 can drive the drying device 9 to adjust its height.

[0027] Specifically, the air drying device 9 includes an air drying box 20, an air drying nozzle 22, a fan 23, and a third battery 24. An air inlet 21 is fixedly opened at the upper end of the air drying box 20, and the air drying nozzle 22 is fixedly connected to the lower end of the air drying box 20. The fan 23 is fixedly connected to both sides inside the air drying box 20, and the third battery 24 is fixedly connected to the center inside the air drying box 20. The fan 23 is electrically connected to the third battery 24 through wires.

[0028] In this embodiment, by connecting the fan 23 to the power supply and driving it to rotate, air can be blown out from the drying nozzle 22 to cool and dry the coated substrate quickly. This allows the coating to be formed quickly, reducing a lot of waiting time. This design adopts a height-adjustable drying design method, which is conducive to the rapid formation of the coating, saves a lot of waiting time, and is more efficient.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
