Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and in particular to a light guide plate cleaning device. Background Art

[0002] Light guide plates (LGPs) generally refer to optical components used in backlight sources and are commonly found in devices such as LCD backlight modules, flat-panel televisions, and electronic display screens. However, during LGP production, particularly during processes like injection molding and surface treatment, the LGP surface is susceptible to contamination with dirt, dust, and grease. This contamination can directly affect light scattering, absorption, or uneven distribution, ultimately impacting LGP quality.

[0003] Currently, in order to improve cleaning efficiency, most existing light guide plate cleaning devices use a roller cleaning method to clean the light guide plate. However, most cleaning rollers are connected to the rotating frame in a hole-shaft embedded rotational manner, which makes it difficult to replace the cleaning roller when it becomes dirty, affecting the cleaning effect of the cleaning device.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1~Figure 2 As shown, this embodiment proposes a light guide plate cleaning device, which mainly includes a workbench 1. The workbench 1 is provided with a conveying component 2, a cleaning component 3, and a power supply. The conveying component 2 includes a plurality of conveying rollers, and each conveying roller is symmetrically and evenly distributed on the workbench 1 with the cleaning component 3 as the center, and each conveying roller is rotatably connected to the workbench, that is, the conveying component 2 is symmetrically and evenly distributed with the cleaning component 3 as the center, so that this embodiment can use the conveying component 2 to send the light guide plate to the cleaning component 3 and send out the cleaning component 3, so as to automatically send in and send out the light guide plate, thereby realizing the automatic cleaning function of the light guide plate.

[0028] The cleaning assembly 3 includes several cleaning rollers 31. The workbench 1 is provided with several first mounting bodies 4 and several second mounting bodies. The second mounting bodies and the first mounting bodies 4 are symmetrically and evenly distributed around each cleaning roller 31. Each cleaning roller 31 is detachably connected between each first mounting body 4 and the second mounting body. In other words, in this embodiment, the first mounting bodies 4 and the second mounting bodies replace the embedded portion of the conventional cleaning roller 31 in the workbench 1 (rotating frame). This allows the cleaning roller 31 to be assembled and disassembled without requiring any adjustment to the workbench 1 (rotating frame). This facilitates assembly and disassembly of the cleaning roller and improves the efficiency of replacing the cleaning roller 31. Furthermore, each first mounting body and the second mounting body are rotatably connected to the workbench 1 (rotating frame), ensuring that the cleaning roller 31 can rotate normally, facilitating cleaning of the light guide plate by the cleaning roller 31.

[0029] Each cleaning roller 31 includes a connecting roller body 311 and a cleaning layer 312. The cleaning layer 312 wraps around the radial surface of the connecting roller body 311. The cleaning layer 312 is preferably made of rubber, which makes the cleaning layer 312 have good softness. In this way, when the cleaning layer 312 effectively adheres to and rolls on the surface of the light guide plate, this softness ensures that the surface of the light guide plate is not damaged during contact, and it can also better adapt to the contours and irregularities of the surface, thereby improving the cleaning effect. At the same time, after multiple cleanings, only the cleaning layer 312 is contaminated, so only the cleaning layer 312 needs to be replaced, which reduces the operating costs of this embodiment. The end faces of the connecting roller body 311 and the cleaning layer 312 are both in contact with the first mounting body 4. With this abutment relationship, the cleaning layer 312 cannot be separated from the connecting roller body 311, ensuring the stability of the overall structure of the cleaning roller 31 during the operation of this embodiment.

[0030] The workbench 1 is provided with a plurality of limiting grooves 11, and each first mounting body 4 and second mounting body is rotatably connected to the limiting groove 11. The end faces of the limiting grooves 11 are used to limit the light guide plate on the conveying component 2 or the cleaning component 3 from contacting the first mounting body 4 or the second mounting body, thereby preventing the light guide plate from being damaged and improving the protective performance of the light guide plate in this embodiment.

[0031] like Figures 1 and 2 As shown, in order to ensure the consistency of rotation of each conveying roller and each cleaning roller 31 in this embodiment, each conveying roller and the first mounting body 4 at the same horizontal height as each conveying roller should be provided with a transmission pulley, and the transmission pulleys are linked by a linkage belt. At the same time, a driving motor is provided at any conveying roller, so that the conveying component 2 and the cleaning component 3 in this embodiment can be driven by one driving source to work, which ensures the consistency between the two while also achieving energy saving and consumption reduction.

[0032] The driving motor in this embodiment is preferably a high-stability motor such as a stepping motor, so as to ensure the stability of the operation of this embodiment.

[0033] like Figure 1~Figure 2 、 Figure 5~Figure 6 As shown, the cleaning assembly 3 in this embodiment includes a plurality of cleaning units, each cleaning unit includes a plurality of cleaning rollers 31, and each cleaning unit is arranged in sequence along the vertical and horizontal directions, that is, there are a plurality of groups of cleaning rollers 31 in this embodiment, and each group of cleaning rollers 31 is symmetrically and evenly distributed around the light guide plate, so that both sides of the light guide plate can be effectively cleaned, avoiding the need for secondary cleaning processes such as turning the light guide plate over, thereby improving the cleaning efficiency of the light guide plate.

[0034] The ends of the upper and lower adjacent first mounting bodies 4 away from the connecting roller body 311 both have a linkage gear 44, and the adjacent linkage gears 44 are engaged with each other. That is, with the help of the meshing relationship between the linkage gears 44, the upper and lower adjacent first mounting bodies 4 can just present opposite rotational motion modes, avoiding the need to additionally set up a driving source with opposite output force such as a driving motor, thereby saving energy and reducing consumption.

[0035] like Figure 3~Figure 4 、 Figure 7 As shown, each of the first mounting body 4 and the second mounting body in this embodiment includes a rotating body 41, a fixing member 42, and an electromagnet 43 for driving the fixing member 42 to move. Specifically, the fixing member 42 is located between the connecting roller body 311 and the electromagnet 43, and the end of the fixing member 42 close to the electromagnet 43 is made of magnetic material. The electromagnet 43 is electrically connected to the power supply. An electronic component such as a bipolar switch that can change the direction of current should be provided between the electromagnet 43 and the power supply, thereby changing the positive and negative poles of the electromagnet 43, so that the fixing member 42 and the electromagnet 43 are in a state of repulsion of the same poles or attraction of the opposite poles. In order to prevent the electromagnet 43 from moving, the electromagnet 43 should be fixedly connected to the workbench 1. The fixing part 42 is connected with the rotating body 41 in a sliding manner. After the positive and negative poles of the electromagnet 43 are replaced, the fixing part 42 can slide on the rotating body 41. Both ends of the connecting roller body 311 have fixing holes 3111 for the fixing part 42 to be embedded. That is, when the fixing part 42 and the electromagnet 43 are in a state of repulsion with the same poles, the fixing part 42 will be embedded in the fixing hole 3111, completing the fixing work of the cleaning roller 31 and realizing the fixing of the cleaning roller 31 on the workbench. When the cleaning roller 31 needs to be removed, it is only necessary to make the electromagnet 43 and the fixing part 42 in a state of attraction with opposite poles so that the fixing part 42 can be separated from the fixing hole 3111, thereby completing the disassembly of the cleaning roller 31.

[0036] The rotating body 41 is rotatably connected to the workbench 1 , that is, the first mounting body 4 or the second mounting body is rotatably connected to the workbench 1 with the rotating body 41 as the main body, ensuring that the first mounting body 4 or the second mounting body can rotate normally.

[0037] At the same time, in order to ensure that the cleaning roller 31 can maintain a coaxial setting with the first mounting body 4 and the second mounting body after reinstallation, each fixing part 42 has a positioning portion 421 at one end close to the connecting roller body 311. The longitudinal cross-section of the positioning portion 421 is a conical structure. The conical structure can provide precise point contact when the coaxiality deviation of the cleaning roller 31 is large, so that as the fixing part 42 moves, the cleaning roller 31 is gradually guided to the center position, completing the coaxiality correction between the first mounting body 4, the second mounting body, and the cleaning roller 31, thereby ensuring the stability of the cleaning roller 31 during rotation and cleaning; and the positioning portion 421 can be embedded in the bottom of the fixing hole 3111, that is, the bottom of the fixing hole 3111 (the end of the fixing hole 3111 away from the fixing part 42) is also a conical structure, so that after the positioning portion 421 is fully embedded in the fixing hole 3111, the fixing hole 3111 and the positioning portion 421 can be in surface contact, thereby increasing the contact area between the two, thereby ensuring the stability of this embodiment during operation.

[0038] like Figure 3~Figure 4 、 Figure 6 As shown, a slide groove 411 is provided inside the rotating body 41 in this embodiment, and the fixing member 42 is slidably connected to the slide groove 411, that is, the fixing member 42 in this embodiment is located inside the rotating body 41, so that the rotating body 41 can better limit the movement of the fixing member 42, prevent the fixing member 42 from deviating, and ensure the accuracy of the movement of the fixing member 42; and each fixing member 42 has a rectangular structure on the axial projection surface of the connecting roller body 311, and the slide groove 411 also has a rectangular structure on the axial projection surface of the connecting roller body 311, so that the rotating body 41 can drive the fixing member 42 to rotate together during the rotation process, and because the fixing member 42 fixes the cleaning roller 31, the cleaning roller 31 will also rotate accordingly, thereby ensuring that the cleaning roller 31 in this embodiment can rotate normally.

[0039] At the same time, considering that each fixing hole 3111 has a buffer layer 3112, the buffer layer 3112 is made of elastic material to prevent the fixing part 42 from being damaged due to the large impact force generated when it contacts the fixing hole 3111 under the action of the repulsive force of the electromagnet 43, thereby ensuring the service life of the fixing part 42.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
