Description

Technical Field

[0001] The utility model relates to the technical field of optical film cleaning, in particular to an ion cleaning device for optical film. Background Art

[0002] Optical films are composed of thin, layered dielectrics, a type of optical material that propagates light beams through their interfaces. During the processing of optical films, both before and after coating, various contaminants such as abrasive powder, oil, dust, and fingerprints may remain on both surfaces. These contaminants not only affect the optical performance of the film but may also adversely affect subsequent coating processes. Therefore, existing optical film cleaning equipment often uses a sticky roller as a cleaning roller to clean the surface of the optical film after production to ensure surface cleanliness.

[0003] However, during the optical film cleaning process, as the number of optical films cleaned increases, dust and other impurities on the optical film continue to adhere to and accumulate on the surface of the sticky roller, resulting in a continuous decline in the cleaning quality of the optical film. In actual use, to ensure the stability of the sticky roller's cleaning quality, the sticky roller must be frequently disassembled and cleaned, which significantly reduces the cleaning efficiency of the optical film. Therefore, it is necessary to provide an optical film cleaning device with stable cleaning quality and high cleaning efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] To help those skilled in the art better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings. The embodiments described herein are merely a portion of the present invention, not all of the present invention. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] Example 1

[0025] refer to Figure 1 As shown, an ion cleaning device for an optical film includes a frame (not shown in the figure), a loading mechanism 1 arranged on one side of the top of the frame, a unloading mechanism 2 arranged on the other side of the top of the frame, and an ion cleaning mechanism 3 arranged on the frame between the loading mechanism 1 and the unloading mechanism 2.

[0026] Specifically, participation Figure 2 and Figure 3 As shown, the unloading mechanism 2 includes a conveyor platform 201 disposed on a frame, and a conveyor belt 202 is rotatably connected to the conveyor platform 201. A conveyor motor (not shown in the figure) is provided on one side of the conveyor belt 202 for driving the conveyor belt 202. The structure of the loading mechanism 2 is the same as that of the unloading mechanism 1.

[0027] The optical film 17 is first placed on the conveyor belt 202 of the conveyor table 201 of the loading mechanism 1 for transportation, and then sent to the ion cleaning mechanism 3 for cleaning, and then enters the conveyor belt 202 of the conveyor table 201 of the unloading mechanism 2 for transportation, and then transported to the next processing procedure.

[0028] The conveyor platform 201 includes two crossbars 203 disposed on either side of the frame, with a plurality of connecting rods 204 interposed between the crossbars 203. A plurality of parallel conveyor rollers 205 are rotatably mounted between the crossbars 203 on either side of the connecting rods 204. The conveyor belt 202 is sleeved over the conveyor rollers 205, and the end of each conveyor roller 205 is rotatably connected to the conveyor motor. When the conveyor motor drives the conveyor rollers 205 to rotate, the conveyor belt 202 is driven, thereby conveying the optical film 17 on the conveyor belt 202, thereby completing the loading or unloading of the optical film 17.

[0029] Combine Figure 1 、 Figure 2 As shown, the ion cleaning mechanism 3 includes a cabinet 301, and one side of the cabinet 301 is provided with a first rectangular groove 302, a second rectangular groove 303 and a third rectangular groove 304 in sequence along the direction close to the ground; a first drawer 5 is slidably connected in the first rectangular groove 302; a first cleaning roller component (not marked in the figure) is provided in the first drawer 5; a second drawer 6 is slidably connected in the second rectangular groove 303, and a dust-sticking roller component (not marked in the figure) is provided in the second drawer 6; a third drawer 7 is slidably connected in the third rectangular groove 304, and a second cleaning roller component (not marked in the figure) is provided in the third drawer 7.

[0030] The two ends of the second rectangular groove 303 in the vertical direction are respectively connected to the first rectangular groove 302 and the third rectangular groove 304 vertically, so that the two ends of the dust-sticking roller in the second rectangular groove 303 can respectively abut the first cleaning roller in the first rectangular groove 302 and the second cleaning roller in the third rectangular groove 304.

[0031] The first, second, and third rectangular slots 302, 303, and 304 provided within cabinet 301 provide modular division of the cleaning sections. The drawer-like, removable design allows for replacement or cleaning of the rollers by simply pulling out the drawer containing the rollers. This simplifies roller replacement and cleaning procedures, improves the maintainability and service life of the device, and enhances roller maintenance efficiency.

[0032] Among them, the sticky roller assembly includes an upper sticky roller 8 and a lower sticky roller 9 for cleaning the upper surface and lower surface of the optical film respectively. The upper sticky roller 8 and the lower sticky roller 9 can be rotatably arranged in the second drawer 6, and the lower sticky roller 9 is located directly below the upper sticky roller 8; a film cleaning channel is formed between the upper sticky roller 8 and the lower sticky roller 9, and the cabinets 301 on both sides of the film cleaning channel are respectively connected to the conveying planes of the loading mechanism 1 and the unloading mechanism 2.

[0033] A guide roller 10 is also provided in the cabinet 301 on either side of the lower sticky roller 9. The conveying plane of the loading mechanism 1, the guide roller 10, the lower sticky roller 9, and the conveying plane of the unloading mechanism 2 are all located on the same horizontal plane. When the optical film 17 passes through the loading mechanism 1 and enters the cabinet 301, it is conveyed by the guide roller 10 and enters the film cleaning passage. At this time, the upper sticky roller 8 and the lower sticky roller 9 respectively contact the upper and lower surfaces of the optical film 17 and rotate synchronously. During rotation, the upper sticky roller 8 and the lower sticky roller 9 continuously clean and absorb dust, impurities, and the like from the upper and lower surfaces of the optical film 17. The optical film 17 is transported forward as the upper and lower sticky rollers 8 and 9 rotate, and then passes through the other guide roller 10 to exit the film cleaning passage and enter the unloading mechanism 2, completing the cleaning process and proceeding with the unloading operation.

[0034] The first cleaning roller component and the second cleaning roller component each include a cleaning roller 11 and a drive motor 12 for driving the cleaning roller 11 to rotate; the cleaning roller 11 in the first drawer 5 abuts against the upper sticky roller 8, driving the upper sticky roller 8 to rotate along the conveying direction and cleaning the surface of the upper sticky roller 8; the cleaning roller 11 in the third drawer 7 abuts against the lower sticky roller 9, driving the lower sticky roller 9 to rotate synchronously with the upper sticky roller 8 along the conveying direction and cleaning the surface of the lower sticky roller 9.

[0035] When optical film 17 passes through ion cleaning mechanism 3, upper and lower sticky rollers 8 and 9 serve as the primary cleaning components, cleaning the film through the action of ions on their surfaces. A cleaning roller 11 in the first drawer 5 abuts against the upper sticky roller 8. As cleaning roller 11 rotates, it drives the upper sticky roller 8 in the conveying direction. During this process, the surface material or structure of cleaning roller 11 (e.g., sticky material) effectively removes dust or contaminants adhering to the surface of upper sticky roller 8, maintaining its cleanliness. Similarly, the cleaning roller 11 in the third drawer 7 abuts against the lower sticky roller 9, driving it to rotate in the conveying direction and cleaning its surface.

[0036] During the continuous conveying process of the optical film 17, the cleaning roller 11 continuously cleans the surfaces of the upper and lower sticky rollers 8 and 9, transferring impurities from the optical film 17 that have adhered to the upper and lower sticky rollers 8 and 9 to the surface of the cleaning roller 11. This ensures that the surfaces of the upper and lower sticky rollers 8 and 9 remain clean for a long time, thereby ensuring that the upper and lower sticky rollers 8 and 9 maintain an efficient and stable ion cleaning effect over a certain period of time, avoiding the problem of a continuous decline in cleaning effect due to the accumulation of impurities on the surfaces of the upper and lower sticky rollers 8 and 9. At the same time, the frequency of disassembly and cleaning of the upper and lower sticky rollers 8 and 9 is effectively reduced, eliminating the need for frequent disassembly and cleaning of the upper and lower sticky rollers 8 and 9 to maintain their cleaning effect, which helps improve the efficiency of film cleaning.

[0037] Among them, reference Figure 3 As shown, a first slide 501 is provided on both sides of the inner wall of the first rectangular slot 302 and the third rectangular slot 304. The first drawer 5 includes two first sliding plates 502, each slidably connected to a corresponding second slide 701. First baffles 503 are installed on both sides of the first sliding plates 502. The cleaning roller 11 is rotatably mounted between the two first baffles 503. The end of the cleaning roller 11 away from the opening of the first rectangular slot 302 is connected to the drive motor 12. The first baffle 503, where the other end of the cleaning roller 11 is located, is connected to a first cover 505 via a first fixing rod 504. The first cover 505 is used to cover the opening of the first rectangular slot 302, and a first handle 506 is provided on the side of the first cover 505 away from the first fixing rod 504 for the user to pull out. The structure of the third drawer 7 is the same as that of the first drawer 5. In this embodiment, the cleaning roller 11 includes a first cleaning roller and a second cleaning roller, which are arranged in parallel in a horizontal direction and rotatably mounted between the two first baffles 503.

[0038] refer to Figure 4 As shown, a second slide 701 is provided on both sides of the inner wall of the third rectangular groove 304, and the second drawer 6 includes two second sliding plates 702 respectively slidably connected to the corresponding second slides 701, and second baffles 703 are installed on both sides of the second sliding plates 702. The upper sticky roller 8 and the lower sticky roller 9 are respectively rotatably installed between the two second baffles 703, and the second baffle where the upper sticky roller 8 is located close to the opening of the third rectangular groove 304 is connected to a second cover body 705 through a second fixed rod 704. The second cover body 705 is used to cover the opening of the second rectangular groove 303, and the second cover body 705 is provided with a second handle 706 for the user to pull out on the side away from the second fixed rod 704.

[0039] In this embodiment, the upper sticky roller 8 includes a first upper sticky roller and a second upper sticky roller which are arranged in parallel along the transverse direction and are respectively rotatably installed between the two second baffles; the lower sticky roller includes a first lower sticky roller and a second lower sticky roller which are arranged in parallel along the transverse direction and are respectively rotatably installed between the two second baffles, and the first lower sticky roller and the second lower sticky roller are respectively located directly below the first upper sticky roller and the second upper sticky roller.

[0040] The larger diameter of the cleaning roller 11 increases its contact area with the upper or lower sticky roller, thereby more effectively removing dust, contaminants, or residues adhering to the sticky roller surface. This also allows the cleaning roller 11 to accommodate more dust and contaminants, extending the time between replacement and cleaning of the cleaning roller 11, thereby improving membrane cleaning efficiency.

[0041] refer to Figure 1 As shown, a controller 13 is installed in the cabinet 301, and a touch screen 14 is installed on the cabinet 301. The touch screen 14 is electrically connected to the drive motor 12 and the conveyor motor, and is respectively electrically connected to the controller 13. The touch screen 14 can be used to control the drive motor 12 and the conveyor motor, thereby controlling the loading and unloading of the optical film 17 of the cleaning device and the cleaning process.

[0042] A buzzer 15 and an alarm light 16 are provided above the cabinet 301, and the buzzer 15 and the alarm light 16 are electrically connected to the controller 13. When an abnormality occurs in the operation of the device, the buzzer 15 and the alarm light 16 can be used to give an early warning.

[0043] The working principle of the ion cleaning device for an optical film provided in this embodiment is as follows: the optical film 17 is placed on the conveyor belt 202 of the conveying platform 201 of the loading mechanism 1 for transmission, and the optical film 17 is fed into the ion cleaning mechanism 3. At this time, the optical film 17 is conveyed by the guide roller 10 and enters the film cleaning channel. At this time, the upper sticky roller 8 and the lower sticky roller 9 are respectively in contact with the upper and lower surfaces of the optical film 17 to clean and absorb dust, impurities, etc. on the upper and lower surfaces of the optical film 17; at the same time, the driving motor 12 drives the cleaning roller 11 to rotate, thereby driving the upper sticky roller 8 and the lower sticky roller 9 in contact with the cleaning roller 11 to rotate synchronously and transport them along the conveying direction, while cleaning the surfaces of the upper sticky roller 8 and the lower sticky roller 9. Finally, the optical film 1 is conveyed 7 through another guide roller 10 to leave the film cleaning channel and enter the unloading mechanism 2 to complete the cleaning and perform the unloading operation.

[0044] Example 2

[0045] refer to Figure 5 and Figure 2As shown, compared with Example 1, Example 2 is distinguished by the fact that two spiral grooves 103 and 104 are provided on the surface of the guide roller 10, and the two spiral grooves 103 and 104 are wound around the guide roller 10 in opposite directions. Specifically, the guide roller 10 includes a rotating shaft 101 rotatably mounted within the cabinet 301 and a roller body 102 mounted on the rotating shaft 101. The roller body 102 has two spiral grooves 103 and 104 on its surface, and the two spiral grooves 103 and 104 are wound around the roller body 102 in opposite directions. Preferably, each rotating shaft 101 is provided with a rotary motor for driving the rotating shaft 102 to rotate.

[0046] As the optical film 17 passes through the guide roller 10 and enters the film cleaning channel, it may experience deviation during its passage from the guide roller 10 to the film cleaning channel and then exit the channel via the other guide roller 10, due to factors such as the parallelism and installation accuracy of the guide roller 10, upper and lower sticky rollers 8 and 9, and the stability of the cabinet 301 installation. Excessive deviation can cause the optical film 17 to contact the sidewall of the cabinet 301 and prevent it from being smoothly conveyed to the unloading mechanism 2. By providing two spiral grooves 103 and 104 wound in opposite directions on the surface of the roller body 102 of the guide roller 10, the optical film 17 guided by the guide roller 10 experiences opposing guiding forces from the two spiral grooves 103 and 104. This ensures that the optical film 17 remains in the position it initially entered the guide roller 10 and maintains this position as it enters the film cleaning channel. In this embodiment, the optical film 17 is positioned at the center of the guide roller 10 upon entering the guide roller 10.

[0047] Among them, when the optical film 17 has not fully entered the film cleaning channel, while the upper sticky roller 8 and the lower sticky roller 9 clean the portion of the optical film 17 that has entered, the two spiral grooves 103 on the guide roller 10 maintain the position of the optical film 17 unchanged, offsetting the influence that the upper sticky roller 8 and the lower sticky roller 9 may have on the position of the optical film 17. When the optical film 17 fully enters the film cleaning channel, the cleaned portion of the optical film 17 is transferred out by the other guide roller 10 and its position is maintained unchanged; even when the optical film 17 fully enters the film cleaning channel, the cleaned portion of the optical film 17 is not transferred out by the other guide roller 10, because the guide roller 10 at the entrance of the film cleaning channel maintains the position of the optical film 17 unchanged for a period of time, the deviation of the optical film 17 caused by the upper sticky roller 8 and the lower sticky roller 9 is within a controllable range, so that the optical film 17 can still be transferred to the unloading mechanism 3.

[0048] Example 3

[0049] Compared with Example 2, the difference of Example 3 is that Figure 2 and Figure 6 As shown, the ion cleaning mechanism further includes an ion static removal component 18 ; the ion static removal component 18 is arranged above the conveying plane of the unloading mechanism 2 , and the ion static removal component is used to remove static electricity on the surface of the optical film 17 .

[0050] Specifically, the ion static removal assembly 18 includes two mounting plates 181 mounted on corresponding crossbars 203 of the unloading mechanism 18. A fixing frame 182 is provided between the two mounting plates 181. An ion static rod 183 is provided on the fixing frame 182. The ion static rod 183 forms a unloading channel for unloading the optical film 17 between the ion static rod 183 and the conveying plane of the unloading mechanism 2. The ion static rod 183 is electrically connected to the control.

[0051] When the optical film 17 passes through the film cleaning channel for cleaning, friction with the upper and lower dust-adhesive rollers 8 and 9 causes static electricity to be generated on the surface of the optical film 17. This may cause the optical film 17 to absorb dust or impurities in the air due to static electricity when the optical film 17 is unloaded, causing contamination of the optical film 17. By providing the ion static removal component 18, when the optical film is unloaded through the unloading channel, the positive and negative charges generated by the ion static rods 183 can neutralize the static electricity generated by friction on the optical film 17, so that the surface of the optical film 17 no longer carries static charge, thereby preventing dust and foreign matter from adhering again, further improving the cleanliness of the optical film 17, and ensuring high-quality cleaning of the optical film 17.

[0052] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention and are not intended to limit the present invention to the specific embodiments described. Obviously, other modifications and variations may be made based on the contents of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. They are not intended to limit the present invention, and any simple variations of the present invention fall within the scope of protection of the present invention.
