Description
Technical Field
[0001] The utility model relates to the technical field of coating equipment, in particular to a polyimide film coating equipment. Background Technique
[0002] Polyimide films include two categories: pyromellitic polyimide films and biphenyl polyimide films. The former is a product of DuPont in the United States and is prepared from pyromellitic dianhydride and diaminodiphenyl ether. The latter is produced by Ube Industries in Japan and is prepared from biphenyltetracarboxylic dianhydride and diphenyl ether diamine (R type) or m-phenylenediamine (S type).
[0003] In modern coating equipment, an obvious deficiency is the lack of an effective cutting device. For example, a utility model with the patent number CN213078929U discloses a film coating equipment. After the film coating process is completed, this equipment does not have a dedicated cutting tool. When the film is completed with film covering, the user still needs to manually perform the cutting work. This process is both time-consuming and laborious, greatly reducing the work efficiency. Even after the cutting is completed, this equipment does not provide an automatic winding device. Therefore, after the user manually cuts, they still need to manually wind, further increasing the burden on the user. Due to the lack of a cutting device and an automatic winding device, there are great inconveniences in its operation and the efficiency is low. Content of the Utility Model
[0004] The purpose of the utility model is to provide a polyimide film coating equipment to solve the problems raised in the above background technique.
[0005] To achieve the above object, the present utility model provides the following technical solution: A polyimide film coating device, including a conveyor belt, one end of the conveyor belt is provided with a shovel plate, several first legs are provided on both sides of the shovel plate, a first support is provided on one side of each first leg, a spring is fixed on the first support, one end of the spring away from the first support is fixed with a pressing block, a guiding plate is fixed on the pressing block, one end of the guiding plate is connected with a cutting groove, a cutting knife is attached to the cutting groove, a fixture is clamped at one end of the cutting knife, several sliding grooves are provided on the fixture, a fixing ring is fixed on the sliding groove, a first motor is sleeved inside the fixing ring, moving gears are sleeved on two output ends of the first motor, a tooth groove is engaged on the side of each moving gear, brackets are fixed at both ends of the tooth groove, and a guiding groove is fixed between the brackets. Above one end of the guiding plate away from the cutting groove, there is a winding roller, buckles are provided at both ends of the winding roller, the buckles are rotatably connected with the second legs, a fixing block is fixed on the side of the second legs, a second motor is fixed on the fixing block, a driving gear is sleeved on the output end of the second motor, a transmission gear is engaged on the side of the driving gear, and the transmission gear is sleeved on one end of the winding roller. The shovel plate shovels up the coated polyimide film from the conveyor belt and guides it into the cutting groove, and cooperates with the cutting knife to cut the polyimide film. The guiding plate located below the winding roller is pushed upward by the spring below it until it fits the winding roller. When the film wound on the winding roller continuously increases, the guiding plate will be pressed downward, and at the same time, the guiding plate presses the film tightly to make the winding firm.
[0006] Preferably, the cutting knife and the fixture are connected by fixing bolts to fix the cutting knife in the fixture.
[0007] Preferably, blocking blocks are provided at both ends of the guiding groove, and the blocking blocks are fixed on the guiding groove by fixing bolts. The baffle is used to prevent the fixture connected to the sliding groove from sliding out of the guiding groove.

[0009] Preferably, a coating device is provided at one end of the conveyor belt away from the shovel plate to coat the polyimide film.
[0010] Preferably, a second support is provided on the first leg on one side of the tooth groove to provide additional support for the tooth groove.
[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] The utility model realizes the purpose of cutting the film through a cutting knife, a first motor, a sliding groove and a tooth groove. The synergistic effect of the cutting knife and the shovel plate provides conditions for precise cutting. The cutting knife has a sharp edge and a solid structure, and can draw accurate marks on the polyimide film. As a matching tool, the shovel plate has a flat and hard surface to ensure that the polyimide film will not be subjected to unnecessary compression or distortion during the cutting process, thus guaranteeing the dimensional accuracy of the product. By controlling the cutting speed, it can ensure that the edges of the polyimide film are neat, without burrs or cracks, which is crucial for subsequent applications.
[0013] The utility model realizes the purpose of winding the film through a guiding plate, a winding roller and a second motor. During the winding stage, when the thickness of the film accumulated on the winding roller increases, the guiding plate will move downward moderately as the winding layer thickens, maintaining a certain contact pressure. The existence of this pressure ensures the flatness and tightness of the film during the winding process, thereby enhancing the stability of the final product and optimizing the storage and transportation efficiency.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a polyimide film coating device, including a conveyor belt 2. At one end of the conveyor belt 2, there is a scraping plate 9. On both sides of the scraping plate 9, there are several first legs 8. On one side of each first leg 8, there is a first support 6. A spring 5 is fixed on the first support 6. One end of the spring 5 away from the first support 6 is fixed with a pressing block 10. A guiding plate 4 is fixed on the pressing block 10. One end of the guiding plate 4 is connected with a cutting groove 19. A cutting knife 17 is fitted in the cutting groove 19. One end of the cutting knife 17 is provided with a fixture 15. There are several sliding grooves 14 on the fixture 15. A fixed ring 12 is fixed on the sliding grooves 14. A first motor 11 is sleeved inside the fixed ring 12. Two output ends of the first motor 11 are sleeved with moving gears 13. Each moving gear 13 is meshed with a tooth groove 3 on the side. Both ends of the tooth groove 3 are fixed with brackets 20. A guiding groove 18 is fixed between the brackets 20. Above one end of the guiding plate 4 away from the cutting groove 19, there is a winding roller 22. At both ends of the winding roller 22, there are buckles 21. The buckles 21 are rotationally connected with the second legs 26. A fixed block 25 is fixed on the side of the second legs 26. A second motor 24 is fixed on the fixed block 25. The output end of the second motor 24 is sleeved with a driving gear 27. The driving gear 27 is meshed with a transmission gear 23 on the side. The transmission gear 23 is sleeved on one end of the winding roller 22. The scraping plate 9 shovels up the coated polyimide film from the conveyor belt 2 and guides it into the cutting groove 19, cooperating with the cutting knife to cut the polyimide film. The guiding plate 4 located below the winding roller 22 is pushed upward by the spring 5 below it until it fits the winding roller 22. When the film wound on the winding roller 22 continuously increases, it will squeeze the guiding plate 4 downward. At the same time, the guiding plate 4 presses the film tightly to make the winding firm.
[0024] Further, the cutting knife 17 and the fixture 15 are connected by a fixing bolt 16 to fix the cutting knife 17 in the fixture 15.
[0025] Further, both ends of the guiding groove 18 are provided with stoppers. The stoppers are fixed on the guiding groove 18 by fixing bolts 16. The baffles are used to prevent the fixture 15 connected to the sliding groove 14 from sliding out of the guiding groove 18.
[0026] Further, both the buckle 21 and the second leg 26 are provided with convex blocks on the same side. A fixing bolt 16 is sleeved inside the convex blocks for fixing the buckle 21.
[0027] Further, at one end of the conveyor belt 2 away from the scraping plate 9, there is a coating device 1 for coating the polyimide film.
[0028] Further, on one side of the tooth groove 3 on the first leg 8, there is a second support 7 for providing additional support to the tooth groove 3.
[0029] Working principle: The main component is the conveyor belt 2, one end of which is equipped with a shovel plate 9 for shoveling up the coated film from the conveyor belt 2 and guiding it onto the cutting groove 19. Several first legs 8 are installed on both sides of the shovel plate 9, and beside each leg, there is a first support 6. A spring 5 is firmly installed on the latter, and the other end of the spring 5 is connected to a stop block 10. A guiding plate 4 is fixed on this stop block 10. One end of the guiding plate 4 is connected to the cutting groove 19, and a cutting knife 17 is provided in the cutting groove 19, which is responsible for precisely shearing the polyimide film. A fixture 15 is clamped outside the cutting knife 17. The fixture 15 is provided with several sliding grooves 14. Fixed rings 12 are fixed on these sliding grooves 14, and a first motor 11 is sleeved inside. Two output ends of this motor are equipped with moving gears 13, and each moving gear 13 meshes with a corresponding tooth groove 3. The teeth provided in the tooth groove 3 prevent the moving gears 13 sleeved on the first motor 11 from slipping when moving on the tooth groove 3. Both ends of the tooth groove 3 are fixed on a bracket 20, and a guiding groove 18 for guiding is fixed between the brackets 20. Above the end of the guiding plate 4 away from the cutting groove 19, there is a winding roller 22. Both ends of the winding roller 22 are provided with buckles 21, which form a rotational connection with the second legs 26. A fixed block 25 is fixed on one side of the second legs 26, and a second motor 24 is further fixed on it. The output end of the second motor 24 is equipped with a driving gear 27, which meshes with a transmission gear 23, and the transmission gear 23 is then sleeved on one end of the winding roller 22. The working process of the entire coating device 1 starts from the conveyor belt 2. The coated polyimide film is shoveled up by the shovel plate 9 and guided into the cutting groove 19. The first motor 11 rotates to drive the moving gears 13 to rotate, causing them to move on the tooth groove 3, thereby driving the sliding grooves 14 and the cutting knife 17 to move and cut the film. The winding roller 22 is located above the guiding plate 4. As the thickness of the wound film increases, it presses down on the guiding plate 4. The spring 5 below the guiding plate 4 enables it to be tightly pressed against the winding roller 22. This mechanism ensures that the polyimide film is wound tightly while maintaining the necessary tension. The combination of the cutting tool and the clamping device is usually achieved through fixing bolts 16. This method can ensure that the cutting knife 17 is stably clamped in the device. In addition, in order to enhance the structural stability and safety, a stop block structure is designed at both end parts of the guiding groove 18. These stop blocks are also firmly installed on the guiding groove 18 by means of fixing bolts 16 to prevent the fixture 15 connecting the sliding grooves 14 from disengaging from the guiding groove 18, thereby ensuring the continuity and reliability of the operation process. The buckles 21 and the second legs 26 are configured with a convex block design on the same side. Fixed bolts 16 are provided inside these convex blocks to provide a stable locking mechanism, ensuring that the buckles 21 can operate synchronously with the support structure and improving the overall structural strength and stability. For material handling, the conveyor belt 2 is equipped with the coating device 1 at the end away from the shovel plate 9, which is specifically used for surface treatment of the polyimide film to improve its performance or prepare for subsequent processing steps, an important link to improve product quality and process efficiency.
[0030] It should be noted that the entire device is controlled by a total control device. Since the devices matched by the control device are common devices and belong to the existing mature technologies, the electrical connection relationships and specific circuit structures thereof will not be elaborated herein.
[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
