Description

Technical Field

[0001] This utility model belongs to the technical field of optical film coating machine, specifically a pre-scraper mechanism for an optical film coating machine. Background Technology

[0002] An optical film coating machine is a precision mechanical device specifically designed to uniformly coat one or more functional coatings onto the surface of an optical film. Its core function is to meet the high-performance requirements of optical films in fields such as display panels, solar cells, and electronic devices by precisely controlling the thickness, uniformity, and surface quality of the coating.

[0003] In the production and processing of optical film coating, a pre-scraper mechanism is often used. Although the existing pre-scraper mechanism can achieve the function of smoothing the coating in actual use, it generally does not have the function of automatic height adjustment. The coating thickness is mostly adjusted manually. This adjustment method not only increases the workload of the workers, but also affects the production efficiency of optical film coating. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a pre-scraper mechanism for an optical film coating machine, which has the advantage of automatically adjusting the height of the pre-scraper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-scraping mechanism for an optical film coating machine, comprising a support rod, a worktable fixedly connected to the top of the support rod, two vertical rods fixedly connected to the top of the worktable, a pre-scraping blade movably connected between the two vertical rods, a connecting block fixedly connected to the outer side of the pre-scraping blade, the outer surface of the connecting block movably connected to the inner surface of the vertical rod, a first dual-axis motor fixedly connected to the bottom of the worktable, a rotating shaft fixedly sleeved at the other end of the output shaft of the first dual-axis motor, a rotating rod fixedly sleeved on the outer surface of the rotating shaft, a round shaft fixedly sleeved inside the other end of the rotating rod, a T-shaped block movably connected to the outer surface of the round shaft, the top of the T-shaped block fixedly connected to the bottom of the connecting block, and the inner side of the T-shaped block movably connected to the outer side of the worktable and the vertical rod.

[0006] As a preferred technical solution of this utility model, the top of the workbench is fixedly connected to a fixed plate located on the left side of the vertical rod. There are two fixed plates, and the inner surfaces of the two fixed plates are movably sleeved with a movable shaft. The outer surfaces of the movable shafts are fixedly sleeved with a feeding roller.

[0007] As a preferred embodiment of this utility model, a rotating plate is hinged to the top of each of the two fixed plates, and the inner surface of the rotating plate is movably sleeved with the outer surface of the movable shaft.

[0008] As a preferred embodiment of this utility model, a second dual-axis motor located on the left side of the fixed plate is fixedly connected to the top of the workbench. A transmission shaft is fixedly sleeved at the other end of the output shaft of the second dual-axis motor, and a rotating rod is fixedly sleeved on the outer surface of the transmission shaft.

[0009] As a preferred embodiment of this utility model, the inner surface of the rotating rod is movably connected with two cylindrical blocks, and the inner sides of the two cylindrical blocks are fixedly connected to the outer side of the rotating plate.

[0010] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the right side of the top of the workbench, and a card collecting motor is fixedly connected to the front of the mounting plate.

[0011] As a preferred embodiment of this utility model, the other end of the output shaft of the coupon receiving motor is fixedly sleeved with a coupon receiving shaft, and the other end of the coupon receiving shaft passes through the mounting plate and extends to the outside of the mounting plate and is fixedly sleeved with a receiving roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a No. 1 dual-axis motor, rotating shafts, rotating rods, round shafts and T-blocks, will cause the two rotating shafts to rotate when the No. 1 dual-axis motor is running, which will cause the two rotating shafts to rotate, thereby causing the two round shafts to rotate and drive the two T-blocks to move downwards. This will cause the two connecting blocks to drive the pre-scraper blade to move downwards, thus achieving the purpose of automatically adjusting the height of the pre-scraper blade. This solves the problem of the cumbersome manual adjustment of the pre-scraper blade height and improves the production efficiency of optical film coating.

[0014] 2. This utility model, by setting up a second dual-axis motor, a transmission shaft, a rotating rod, a cylindrical block, and a rotating plate, will cause the two transmission shafts to drive the two rotating rods to rotate when the second dual-axis motor is running. The rotation of the two rotating rods will drive the two cylindrical blocks to rotate, which in turn will drive the two rotating plates to rotate and separate from the two fixed plates, thereby removing the limiting effect on the movable shaft and making it easier for workers to replace and place the feeding roller.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a pre-scraper mechanism for an optical film coating machine, including a support rod 1, a worktable 2 fixedly connected to the top of the support rod 1, two vertical rods 3 fixedly connected to the top of the worktable 2, a pre-scraper 4 movably connected between the two vertical rods 3, a connecting block 5 fixedly connected to the outer side of the pre-scraper 4, the outer surface of the connecting block 5 movably connected to the inner surface of the vertical rod 3, a first dual-axis motor 6 fixedly connected to the bottom of the worktable 2, a rotating shaft 7 fixedly sleeved at the other end of the output shaft of the first dual-axis motor 6, a rotating rod 8 fixedly sleeved on the outer surface of the rotating shaft 7, a round shaft 9 fixedly sleeved inside the other end of the rotating rod 8, a T-shaped block 10 movably connected to the outer surface of the round shaft 9, the top of the T-shaped block 10 fixedly connected to the bottom of the connecting block 5, and the inner side of the T-shaped block 10 movably connected to the outer side of the worktable 2 and the vertical rod 3.

[0023] When the No. 1 dual-axis motor 6 is running, it will cause the two rotating shafts 7 to drive the two rotating rods 8 to rotate, which in turn causes the two round shafts 9 to rotate and drive the two T-shaped blocks 10 to move downward, thereby causing the two connecting blocks 5 to drive the pre-scraper 4 to move downward, thus achieving the purpose of automatically adjusting the height of the pre-scraper 4.

[0024] Among them, the top of the workbench 2 is fixedly connected to a fixed plate 11 located on the left side of the vertical rod 3. There are two fixed plates 11. The inner surfaces of the two fixed plates 11 are movably sleeved with a movable shaft 12, and the outer surfaces of the movable shaft 12 are fixedly sleeved with a feeding roller 13.

[0025] The design of the two fixed plates 11 serves to support and stabilize the movable shaft 12 and the feeding roller 13.

[0026] Among them, the top of each of the two fixed plates 11 is hinged with a rotating plate 18, and the inner surface of the rotating plate 18 is movably sleeved with the outer surface of the movable shaft 12.

[0027] The design of the rotating plate 18 serves to limit the movement of the movable shaft 12, preventing the feeding roller 13 from detaching from the fixed plate 11 during feeding.

[0028] The workbench 2 is fixedly connected to the top of the workbench 2 and is located on the left side of the fixed plate 11. The other end of the output shaft of the second dual-axis motor 14 is fixedly sleeved with a transmission shaft 15, and the outer surface of the transmission shaft 15 is fixedly sleeved with a rotating rod 16.

[0029] When the No. 2 dual-axis motor 14 is running, it will cause the two drive shafts 15 to drive the two rotating rods 16 to rotate.

[0030] Among them, two cylindrical blocks 17 are movably connected to the inner surface of the rotating rod 16, and the inner sides of the two cylindrical blocks 17 are fixedly connected to the outer side of the rotating plate 18.

[0031] The rotation of the two rotating rods 16 causes the two cylindrical blocks 17 to rotate, which in turn causes the two rotating plates 18 to rotate, releasing the limiting effect on the movable shaft 12, thus making it easier for the staff to replace the feeding roller 13.

[0032] Among them, a mounting plate 19 is fixedly connected to the right side of the top of the workbench 2, and a ticket collecting motor 20 is fixedly connected to the front of the mounting plate 19.

[0033] The mounting plate 19 is designed to support and fix the ticket collecting motor 20.

[0034] The other end of the output shaft of the card collecting motor 20 is fixedly sleeved with a card collecting shaft 21, and the other end of the card collecting shaft 21 passes through the mounting plate 19 and extends to the outside of the mounting plate 19 and is fixedly sleeved with a card collecting roller 22.

[0035] When the collecting motor 20 is running, it will cause the collecting shaft 21 to drive the collecting roller 22 to rotate and collect the optical film coating.

[0036] Working principle and usage process of this utility model:

[0037] When controlling the different coating thicknesses of the optical film, the second dual-axis motor 14 is started first, which will cause the two drive shafts 15 to drive the two rotating rods 16 to rotate. The rotation of the two rotating rods 16 will drive the two cylindrical blocks 17 to rotate, which in turn will drive the two rotating plates 18 to rotate and separate from the two fixed plates 11, thereby releasing the limiting effect on the movable shaft 12, making it easier for the operator to place the feeding roller 13. Then, the second dual-axis motor 14 is started again to drive the two rotating plates 18 to reset and limit the feeding roller 13.

[0038] Then, starting the first dual-axis motor 6 will cause the two rotating shafts 7 to drive the two rotating rods 8 to rotate, which in turn causes the two round shafts 9 to rotate and drive the two T-blocks 10 to move downwards. This causes the two connecting blocks 5 to drive the pre-scraper 4 to move downwards, thus achieving the purpose of automatically adjusting the height of the pre-scraper 4 and improving the production efficiency of optical film coating. After that, starting the collecting motor 20 will cause the collecting shaft 21 to drive the collecting roller 22 to rotate and collect the optical film coating. At the same time, under the action of the pre-scraper 4, the optical film coating is smoothed.
