Description

Technical Field

[0001] This utility model relates to the field of polyimide film processing technology, and in particular to a manual film forming table for polyimide films. Background Technology

[0002] Polyimide film is the world's best-performing thin-film insulating material. It is formed by polycondensation of PMDA and diamine (ODA) in a highly polar solvent, followed by casting and imidization. During the film-forming process, the polyimide film needs to be scraped off a glass plate. However, different markets require different thicknesses of polyimide film. Existing manual film-forming tables are not easy to adjust the doctor blade during film formation, resulting in films that do not meet market requirements. At the same time, if the doctor blade is not wound up in time, the scraped polyimide film will accumulate, affecting the quality of the film. Therefore, we propose a manual polyimide film-forming table. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. In the process of forming polyimide films, the polyimide film needs to be scraped off a glass plate. However, different markets require different thicknesses of polyimide films. In the existing manual film forming table, the scraper is not easy to adjust during film forming, resulting in the film not meeting market requirements. At the same time, if the scraper cannot be rolled up in time, the scraped polyimide film will accumulate, affecting the quality of the film.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A manual film forming table for polyimide film includes a film scraping platform, sliding mechanisms are installed on both sides of the film scraping platform, and a winding assembly is installed on the top of the film scraping platform behind the sliding mechanisms.

[0006] The sliding mechanism includes a sliding groove, which is opened on both sides of the film scraping platform. A sliding block is slidably connected inside the sliding groove. Limiting grooves are opened at both the upper and lower ends of the sliding groove. A limiting block is installed at the end of the sliding block facing the sliding groove, corresponding to the limiting groove. A lifting component is installed at the end of the sliding block away from the limiting block. A film scraping component is installed between the lifting components.

[0007] Furthermore, the lifting assembly includes a lifting platform, which is installed on both sides of the film scraping platform at the end of the sliding block away from the limiting block. A lifting groove is provided on the opposite side of the lifting platform. A synchronous motor is installed on the top of the lifting platform. The output end of the synchronous motor extends into the lifting groove and is equipped with a lead screw. A lead screw nut is sleeved around the lead screw.

[0008] Furthermore, the film scraping assembly includes a housing, which is installed between the lifting platforms on the lead screw nut. A through groove is provided at the bottom of the housing, and scrapers are installed on the inner walls at both ends of the housing corresponding to the through groove. A first pressure roller is rotatably connected to the inner walls at both ends of the housing below the scraper. A film outlet is provided on the inner wall of the housing behind the first pressure roller.

[0009] Furthermore, the winding assembly includes device blocks, which are installed on both sides of the top of the film scraping platform behind the lifting platform. A winding roller is rotatably connected between the device blocks, and one end of the winding roller extends out of a device block on one side and is equipped with a gear.

[0010] Furthermore, a rack is installed on the side of the lifting platform near the winding assembly corresponding to the gear, and the gear and the rack are meshed together.

[0011] Furthermore, a second pressure roller is installed on the side of the housing away from the winding assembly.

[0012] Furthermore, the lifting platform has an adjustment scale on the side away from the winding assembly, and a push rod is installed on the side of the lifting platform away from the film scraping platform.

[0013] Furthermore, support seats are installed at the four corners of the bottom of the film scraping platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The synchronous motor at the top of the lifting platform drives the lead screw to rotate forward and backward, causing the lead screw nut to move up and down, thus moving the film scraping assembly. The scale is adjusted according to the required film thickness. Once adjusted, the push rod is pushed, and the second pressure roller mounted on the housing rolls forward to flatten the film in front. Then, the polyimide film is scraped off by the movement of the doctor blade. The scraped film is then passed through the film outlet and fixed on the winding roller. With manual pushing, the rack moves, driving the gear to rotate, which in turn rotates the winding roller to wind up the scraped polyimide film. This achieves both doctor blade adjustment and polyimide film winding, preventing accumulation and improving film quality. Attached Figure Description

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a manual film forming table for polyimide film, including a scraping platform 1 for loading film forming equipment, sliding mechanisms 2 installed on both sides of the scraping platform 1 for easy manual pushing to perform film forming operation, and a winding assembly 3 installed at the top of the scraping platform 1 behind the sliding mechanism 2 for winding the scraped polyimide film to prevent the polyimide film from accumulating.

[0027] The sliding mechanism 2 includes a sliding groove 21, which is opened on both sides of the film scraping platform 1. A sliding block 22 is slidably connected inside the sliding groove 21. The push rod 7 is manually pushed to make the sliding block 22 slide in the sliding groove 21. Limiting grooves 23 are opened at both the upper and lower ends of the sliding groove 21. A limiting block 24 is installed at the end of the sliding block 22 facing the sliding groove 21 corresponding to the limiting groove 23. The limiting groove 23 and the limiting block 24 cooperate with each other to prevent the sliding block 22 from falling off during the sliding process. A lifting component 25 is installed at the end of the sliding block 22 away from the limiting block to adjust the height of the film scraping component 26, thereby controlling the thickness of the film. The film scraping component 26 is installed between the lifting components 25 to scrape the polyimide film neatly and flatly.

[0028] Example 2

[0029] like Figure 1-4 As shown, the lifting assembly 25 includes a lifting platform 251, which is installed on both sides of the film scraping platform 1 at the end of the sliding block 22 away from the limiting block. The lifting platform 251 is used to load the lifting equipment. A lifting groove 252 is opened on the opposite side of the lifting platform 251. A synchronous motor 253 is installed on the top of the lifting platform 251. An adjustment scale 6 is provided on the surface of the side of the lifting platform 251 away from the winding assembly 3. A push rod 7 is installed on the side of the lifting platform 251 away from the film scraping platform 1. The push rod 7 is convenient for manual pushing. The output end of the synchronous motor 253 extends into the lifting groove 252 and is equipped with a lead screw 254. A lead screw nut 255 is sleeved on the periphery of the lead screw 254. The synchronous motor 253 on the top of the lifting platform 251 drives the lead screw 254 to rotate forward and backward, which drives the lead screw nut 255 to move up and down, so that the film scraping assembly 26 moves. The adjustment scale 6 is observed and adjusted according to the required film scraping thickness.

[0030] The film scraping assembly 26 includes a housing 261, which is installed between the lifting platforms 251 on the lead screw nut 255. A through groove 262 is provided at the bottom of the housing 261. A scraper 263 is installed on the inner wall of both ends of the housing 261 corresponding to the through groove 262. The scraper 263 is used for scraping the film and is generally set at a 15-degree angle. A first pressure roller 264 is rotatably connected to the inner wall of both ends of the housing 261 below the scraper 263 to assist the sliding of the film scraping assembly 26. A film outlet 265 is provided on the inner wall of the housing 261 behind the first pressure roller 264 to pass one end of the scraped film through the film outlet 265 and fix it on the winding roller 32.

[0031] The winding assembly 3 includes a device block 31, which is installed on both sides of the top of the film scraping platform 1 behind the lifting platform 251. A winding roller 32 is rotatably connected between the device blocks 31. The winding roller 32 is used to wind up the scraped film. One end of the winding roller 32 extends out of one side of the device block 31 and is equipped with a gear 33. A rack 4 is installed on the side of the lifting platform 251 near the winding assembly 3, corresponding to the gear 33. The gear 33 and the rack 4 are meshed. When pushed manually, the rack 4 moves, thereby driving the gear 33 to rotate, which in turn causes the winding roller 32 to rotate, thus winding up the scraped polyimide film. A second pressure roller 5 is installed on the side of the housing 261 away from the winding assembly 3, which is used to press the film in front of the housing 261 flat. Support seats 8 are installed at the four corners of the bottom of the film scraping platform 1 to stabilize the entire assembly.

[0032] The working process of this utility model is as follows: When using a manual polyimide film forming table, the synchronous motor 253 at the top of the lifting platform 251 drives the lead screw 254 to rotate forward and backward, which drives the lead screw nut 255 to move up and down, causing the scraping assembly 26 to move. The scale 6 is adjusted according to the required scraping film thickness. After adjustment, the push rod 7 is manually pushed, causing the sliding block 22 to slide in the sliding groove 21. The second pressure roller 5 installed on the housing 261 will roll forward with the push, pressing the film in front flat. Then, with the movement of the scraper 263, the polyimide film is scraped off. Then, one end of the scraped film is passed through the film outlet 265 and fixed on the winding roller 32. With manual pushing, the rack 4 moves, thereby driving the gear 33 to rotate, which in turn makes the winding roller 32 rotate, and the scraped polyimide film is wound up.

[0033] 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.
