Description

Technical Field

[0001] The present invention relates to the technical field of polarizing plate production, and in particular to a high-efficiency dust removal device for a polarizing plate production line and a dust removal method thereof. Background Art

[0002] Polarizers are key components of optoelectronic display devices such as liquid crystal displays (LCDs), and their production process has extremely high requirements for environmental cleanliness. Polarizer production is usually carried out in specially designed dust-free workshops, which are designed to create a highly controlled environment to minimize airborne particles, harmful air components, bacteria and other pollutants. The design of a dust-free workshop not only requires the effective removal of these pollutants, but also requires precise control of the room's temperature, cleanliness, pressure, airflow velocity and distribution, noise and vibration levels, lighting conditions, and static electricity conditions to meet specific production needs.

[0003] In the production process of polarizing plates, coating is a crucial step, which involves evenly coating a specific material on a substrate. After coating, the polarizing plate needs to be accurately transferred to the next process. However, during this transfer process, if the tiny impurities on the film surface are not removed promptly and effectively, these impurities are likely to adhere to the subsequent rollers or other transmission equipment. Once impurities are embedded in the rollers, they may cause scratches, indentations or other forms of physical damage to the surface of the polarizing plate during subsequent processing, seriously affecting the quality of the product.

[0004] At present, sticky rollers are commonly used to remove impurities on the film, and then sticky paper is used to remove the impurities accumulated on the sticky roller, so as to improve the cleaning efficiency of the sticky roller on the film. However, this method has a significant drawback: as the sticky paper is used for a longer time, its adhesion ability will gradually weaken, resulting in a significant reduction in the cleaning effect of the sticky roller. In order to maintain the cleaning effect, the production line operation has to be interrupted and the sticky paper has to be manually replaced, which will reduce the production efficiency of the polarizing plate.

[0032] The sticky roller self-cleaning unit 300 is located at the top of the sticky roller 101 and is connected to the support unit 200 and the drive mechanism. The sticky roller self-cleaning unit 300 includes a sticky roller self-cleaning component 301 and a winding drive component 302. The winding drive component 302 drives the sticky roller self-cleaning component 301 to move and self-clean the surface of the sticky roller 101 through its winding action.

[0033] Specifically, Figure 2 The sticky roller self-cleaning unit 300 is located between the top plate 201 and the sticky roller 101 , and the top of the sticky roller self-cleaning component 301 is fixedly connected to the bottom of the top plate 201 .

During the rotation of the sticky roller 101, the sticky roller 101 is automatically cleaned by the arc-shaped self-cleaning area 301-5a on the sticky paper 301-5, so as to ensure that the sticky roller 101 remains in a clean state, thereby ensuring the cleaning effect of the sticky roller 101 on the polarizing plate film surface.

[0035] Example 2 Refer to the following figure Figure 5 and Figure 7-8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the dust-sticky roller self-cleaning unit 300 also includes a winding drive assembly 302, and the winding drive assembly 302 is connected to the connecting shaft 301-7, the rotating shaft 103 and the top plate 201.

[0036] Specifically, Figure 5 A pair of winding drive components 302 are symmetrically arranged on the front and rear sides of the dust-sticky roller self-cleaning component 301. The winding drive component 302 includes a first winding drive mechanism 302-1 connected to the connecting shaft 301-7 and the top plate 201, and a second winding drive mechanism 302-2 fixedly connected to the rotating shaft 103 and the first winding drive mechanism 302-1.

[0037] like Figure 7The first winding drive mechanism 302-1 includes a first pulley 302-11 fixedly connected to the end of the connecting shaft 301-7 away from the winding roller 301-3, and a second pulley 302-12 located directly above the rotating shaft 103. The center of the second pulley 302-12 is fixedly connected to a mounting shaft, and a fourth mounting plate 302-13 is rotatably mounted on the rear end of the mounting shaft through a bearing. The top end of the fourth mounting plate 302-13 is fixedly connected to the bottom of the top plate 201. The first pulley 302-11 and the second pulley 302-12 are connected by a belt 302-14. The second winding drive mechanism 302-2 is fixedly connected to the second pulley 302-12 and the rotating shaft 103.

[0038] like Figure 8 The second winding drive mechanism 302-2 includes a connecting disk 302-21 fixedly connected to the side of the second pulley 302-12 away from the fourth mounting plate 302-13 and a connecting sleeve 302-22 fixedly sleeved on the outside of the rotating shaft 103, the central axis of the connecting disk 302-21 is consistent with the central axis of the second pulley 302-12, a protrusion 302-23 is fixedly connected to the side of the connecting disk 302-21 away from the second pulley 302-12, and six rotating start rods 302-24 are fixedly connected to the side of the protrusion 302-23 in an annular array, the central axis of the connecting sleeve 302-22 is consistent with the central axis of the rotating shaft 103, and a toggle rod 302-25 is fixedly connected to the side of the connecting sleeve 302-22. 02-25 is fixedly connected with a boss 302-26 on one side of the rotary start rod 302-24. Whenever the lever 302-25 rotates one circle, the boss 302-26 thereon will contact the lowest rotary start rod 302-24, and after contact, the rotary start rod 302-24 will be rotated 60°, thereby driving the second pulley 302-12 to rotate. Every time a rotary start rod 302-24 is turned and rotated, the sticky paper 301-5 will move accordingly, so that the used arc-shaped self-cleaning area 301-5a will be removed. At the same time, the new part of the sticky paper 301-5 will fill the position in contact with the sticky roller 101, forming a new arc-shaped self-cleaning area 301-5a.

[0039] The remaining structures are the same as those of Example 1.

[0040] When the driving motor 104 drives the rotating shaft 103 and the dust-sticking roller 101 to rotate, the connecting sleeve 302-22 also rotates accordingly, and the connecting sleeve 302-22 drives the toggle rod 302-25 and the boss 302-26 to rotate synchronously; when the boss 302-26 contacts one side of the lowest rotation start rod 302-24, the boss 302-26 continues to rotate and pushes the rotation start rod 302-24 to rotate, and the rotation start rod 302-24 drives the second pulley 302-12 to rotate through the convex block 302-23 and the connecting disk 302-21, and the second pulley 302-12 is driven by the belt 302-14 The first pulley 302-11 is driven to rotate, and the first pulley 302-11 drives the winding roller 301-3 to rotate and rewind through the connecting shaft 301-7. This process can remove the arc-shaped self-cleaning area 301-5a with impurities from the top of the sticky roller 101, and at the same time, the sticky paper 301-5a without impurities is filled to the position in contact with the top of the sticky roller 101, forming a new arc-shaped self-cleaning area 301-5a, thereby ensuring that the sticky paper 301-5 can continuously and effectively clean the sticky roller 101, thereby further ensuring the cleaning effect of the sticky roller 101 on the polarizing plate film surface. In addition, there is no need to interrupt the production line operation, so it is not easy to affect the production efficiency of the polarizing plate. In addition, by driving each rotating start rod 302-24 to rotate 60° through the coordinated use of the wave rod 302-25, the boss 302-26, etc., the new part of the sticky paper 301-5 can be just filled into the used arc-shaped self-cleaning area 301-5a, thereby ensuring the maximum utilization of the sticky paper 301-5 and effectively avoiding unnecessary waste.

[0041] The dust removal method using the above-mentioned high-efficiency dust removal device for a polarizing plate production line is as follows: starting the driving motor 104, the output end of the driving motor 104 drives the sticky roller 101 to rotate through the rotating shaft 103, and during the rotation process, the sticky roller 101 removes impurities on the surface of the polarizing plate at its bottom to achieve automatic cleaning of the polarizing plate; at the same time, when the sticky roller 101 rotates, the arc-shaped self-cleaning area 301-5a on the sticky paper 301-5 will remove impurities on the sticky roller 101, ensuring that the sticky roller 101 continues to maintain a clean state, thereby ensuring the cleaning effect of the sticky roller 101 on the polarizing plate film surface. When the driving motor 104 drives the rotating shaft 103 and the dust-sticking roller 101 to rotate, the connecting sleeve 302-22 also rotates accordingly, and the connecting sleeve 302-22 drives the toggle rod 302-25 and the boss 302-26 to rotate synchronously; when the boss 302-26 contacts one side of the lowest rotation start rod 302-24, the boss 302-26 continues to rotate and pushes the rotation start rod 302-24 to rotate, and the rotation start rod 302-24 drives the second pulley 302-12 to rotate through the convex block 302-23 and the connecting disk 302-21, and the second pulley 302-12 drives the first belt pulley 302-14 through the belt The wheel 302-11 rotates, and the first pulley 302-11 drives the winding roller 301-3 to rotate and rewind through the connecting shaft 301-7. This process can remove the arc-shaped self-cleaning area 301-5a with impurities adhered to it from the top of the sticky roller 101, and at the same time, the sticky paper 301-5 without impurities is replaced to the position in contact with the top of the sticky roller 101, forming a new arc-shaped self-cleaning area 301-5a, ensuring that the sticky paper 301-5 can continuously and effectively clean the sticky roller 101, thereby further ensuring the cleaning effect of the sticky roller 101 on the polarizing plate film surface, and not easily causing waste of the sticky paper 301-5. As the convex column 302-26 continues to rotate and separates from the rotating start rod 302-24, the second pulley 302-12 stops rotating and the sticky paper 301-5 also stops moving; when the convex column 302-26 rotates again and contacts one side of the rotating start rod 302-24, it will drive the second pulley 302-12 to rotate again, thereby realizing the intermittent movement of the sticky paper 301-5.

10. The dust removal method of the high-efficiency dust removal device of the polarizing plate production line according to any one of claims 1 to 9, comprising the following steps: Step 1: starting the driving motor (104); the output end of the driving motor (104) drives the dust sticking roller (101) to rotate via the rotating shaft (103); during the rotation process, the dust sticking roller (101) removes impurities on the surface of the polarizing plate at its bottom, thereby achieving automatic cleaning of the polarizing plate; at the same time, when the dust sticking roller (101) rotates, the arc-shaped self-cleaning area (301-5a) on the dust sticking paper (301-5) removes impurities on the dust sticking roller (101), thereby ensuring that the dust sticking roller (101) is continuously kept in a clean state, thereby ensuring the cleaning effect of the dust sticking roller (101) on the film surface of the polarizing plate; Step 2: When the driving motor (104) drives the rotating shaft (103) and the dust-adhesive roller (101) to rotate, the connecting sleeve (302-22) also rotates accordingly, and the connecting sleeve (302-22) drives the toggle rod (302-25) and the boss (302-26) to rotate synchronously; when the boss (302-26) contacts one side of the lowest rotation start rod (302-24), the boss (302-26) continues to rotate and pushes the rotation start rod (302-24) to rotate, and the rotation start rod (302-24) drives the second pulley (302-12) to rotate through the convex block (302-23) and the connecting disk (302-21), and the second pulley (302-12) is driven by the belt (302-14). The first pulley (302-11) is driven to rotate, and the first pulley (302-11) drives the winding roller (301-3) to rotate and wind up through the connecting shaft (301-7). This process can remove the arc-shaped self-cleaning area (301-5a) with impurities adhered to it from the top of the sticky roller (101), and at the same time, the sticky paper (301-5) without impurities adhered to it is replaced to the position in contact with the top of the sticky roller (101), forming a new arc-shaped self-cleaning area (301-5a), ensuring that the sticky paper (301-5) can continuously and effectively clean the sticky roller (101), thereby further ensuring the cleaning effect of the sticky roller (101) on the film surface of the polarizing plate, and not easily causing waste of the sticky paper (301-5); Step 3: As the convex column (302-26) continues to rotate and separates from the rotating start rod (302-24), the second pulley (302-12) stops rotating and the dust sticking paper (301-5) also stops moving; when the convex column (302-26) rotates again and contacts one side of the rotating start rod (302-24), it drives the second pulley (302-12) to rotate again, thereby achieving the intermittent movement of the dust sticking paper (301-5). This process is repeated, ensuring efficient dust removal on the polarizing plate film surface.
