Description

Technical Field

[0001] This utility model relates to the field of light guide plate production, specifically a light guide plate cleaning machine. Background Technology

[0002] During the production and assembly of light guide plates, any tiny impurities adhering to their surface will form obvious bright spots, dark spots, or hazy defects on the final product (such as an LCD screen), seriously affecting display quality and yield. Therefore, it is necessary to use a cleaning machine to clean dust, particles, fibers, and other contaminants from the surface of the light guide plate. Current cleaning machines consist of components such as a conveying mechanism, an ion fan, and a dust-adhesive roller. The conveying mechanism is responsible for conveying the light guide plate, the ion fan is responsible for neutralizing the static electricity on the surface of the light guide plate, and the dust-adhesive roller can adhere to the dust on the surface of the light guide plate, thus achieving the purpose of cleaning the light guide plate.

[0003] Existing light guide plate cleaning machines are equipped with a dust-adhesive roller to adhere to dust on the light guide plate. As a core cleaning component, the dust-adhesive roller needs to be replaced or cleaned regularly to ensure cleaning effectiveness. However, the dust-adhesive rollers of traditional equipment are usually installed using a complex structure (such as multiple sets of bolts for fixing or integrated connection). When fixed with multiple sets of bolts, disassembly requires removing the bolts one by one before the dust-adhesive roller can be removed for replacement. Installation also requires reinstalling multiple bolts to fix the dust-adhesive roller, making the disassembly and assembly process cumbersome and time-consuming. This leads to low maintenance efficiency and reduces the efficiency of disassembly and replacement of the dust-adhesive roller. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a light guide plate cleaning machine to solve the technical problem of inconvenience in disassembling and replacing the dust roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a light guide plate cleaning machine, comprising a machine body and a lifting frame. A roller conveyor is installed on the top of the machine body, and a motor is installed on the outer surface of the lifting frame. Two rotating shafts are connected inside the lifting frame via bearings, and each of the two rotating shafts has a positioning groove at its top. A positioning block is inserted into the positioning groove, and a roller is installed between the two positioning blocks. A dust-adhesive roller is installed on the outer wall of the roller. Slots are opened inside both the rotating shaft and the roller, and a plug shaft is inserted into the slot. One end of the plug shaft extends through to the outside of the lifting frame and is fitted with a pull plate. A threaded groove is opened on the back of the lifting frame, and a threaded cap is threadedly connected inside the threaded groove.

[0006] By adopting the above technical solution, the machine body can support the roller conveyor, which can transport the light guide plate, allowing the light guide plate to pass smoothly through the cleaning area.

[0007] Furthermore, a motor is mounted on the outer surface of the lifting frame, and the output end of the motor is connected to a rotating shaft.

[0008] By adopting the above technical solution, when the motor is working, it can drive the shaft connected to it to rotate, which in turn drives the insert shaft to rotate, and then drives the roller shaft to rotate.

[0009] Furthermore, the insert shaft is adapted to the slot, and the roller shaft and the dust-adhesive roller are detachably connected to the rotating shaft.

[0010] By adopting the above technical solution, the insert shaft and slot are precisely matched to ensure a tight and secure connection; at the same time, the roller shaft and the dust-adhesive roller can be detached from the rotating shaft.

[0011] Furthermore, the back of the pull plate is fitted against the inner wall of the threaded cover, and the outer wall of the threaded cover is provided with anti-slip texture.

[0012] By adopting the above technical solution, the pull plate fits into the inner wall of the threaded cover. After the threaded cover is tightened, it can limit the insertion shaft and prevent axial movement. The anti-slip texture increases the friction of the hand, making it easier for the operator to tighten the threaded cover.

[0013] Furthermore, a protective cover is installed on the top of the roller conveyor, and openings are provided on both sides of the protective cover.

[0014] By adopting the above technical solution, the protective cover can shield and protect the dust roller, and the opening provides a channel for the light guide plate to enter and exit, ensuring continuous conveying.

[0015] Furthermore, a cover plate is installed on the top of the protective cover via a hinge, and a latch is installed between the cover plate and the protective cover.

[0016] By adopting the above technical solution, the cover can be opened and closed by hinges, which facilitates the maintenance of the internal dust roller; while the locking buckle ensures that the cover is tightly closed.

[0017] Furthermore, a threaded rod is threadedly connected to the top of the cover plate, and a lifting frame is connected to the bottom end of the threaded rod via a bearing. Guide rods penetrating the cover plate are installed on both sides of the top of the lifting frame.

[0018] By adopting the above technical solution, the rotation of the threaded rod drives the lifting frame to move up and down, adjusting the height of the dust-adhesive roller; the guide rod limits the tilt of the lifting frame, ensuring stable height adjustment.

[0019] Furthermore, frames are installed on both sides of the roller conveyor, and conveyor belts are installed on the frames.

[0020] By adopting the above technical solution, the conveyor belt can realize the feeding of the light guide plate to be cleaned and the feeding of the light guide plate after cleaning, forming a continuous production line.

[0021] Furthermore, a mounting base and a support plate are respectively installed on one side of the protective cover. An ion fan is installed on one side of the mounting base, and a diversion pipe is fixed on one side of the support plate. Multiple ion nozzles are installed at the bottom of the diversion pipe, and the air inlet end of the diversion pipe is connected to the air outlet end of the ion fan.

[0022] By adopting the above technical solution, the ion fan generates ion wind, which enters the ion nozzle through the diversion pipe. The ion nozzle blows the ion wind in a directional manner onto the light guide plate, neutralizing the static electricity on the surface and preventing the static electricity from re-adsorbing dust.

[0023] Furthermore, a control panel is installed on the outer surface of the machine body, and the control panel is electrically connected to the conveyor belt, roller conveyor, ion fan and motor respectively.

[0024] By adopting the above technical solution, it is convenient for staff to start or stop the conveyor belt, roller conveyor, ion fan and motor through the control panel.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model is equipped with a shaft insert, slot, rotating shaft, pull plate, threaded groove and threaded cover. When the sticky roller needs to be disassembled, the cover plate is first opened so that the sticky roller can be rotated out from inside the protective cover. Then the threaded cover is rotated so that the threaded cover can be unscrewed from inside the threaded groove. Then the shaft insert is pulled by the pull plate so that the shaft can be moved out from the slot. At this time, the sticky roller is no longer clamped or limited. In this way, the sticky roller can be removed so that the sticky roller can be quickly disassembled. This method does not require disassembling a complex structure and the disassembly process is relatively simple, thereby improving the disassembly efficiency of the sticky roller.

[0027] 2. This utility model is equipped with a positioning block and a positioning groove. After the positioning block is inserted into the positioning groove, the roller shaft can be positioned so that the slot on the roller shaft can be aligned with the slot on the rotating shaft. This makes it easier to insert the insertion shaft into the slot for limiting. At the same time, the positioning groove and the positioning block ensure that the dust-adhesive roller rotates coaxially, and the threaded cover fits with the pull plate at the end of the insertion shaft, which can prevent the parts from moving and improve the stability of the insertion shaft.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A light guide plate cleaning machine, such as Figures 1-9As shown, the device includes a body 1 and a lifting frame 17. A roller conveyor 5 is installed on the top of the body 1, which supports the roller conveyor 5. The roller conveyor 5 can transport a light guide plate, allowing the light guide plate to pass smoothly through the cleaning area. A motor 19 is installed on the outer surface of the lifting frame 17. Two rotating shafts 20 are connected inside the lifting frame 17 via bearings. The top of each of the two rotating shafts 20 is provided with a positioning groove 24. A positioning block 25 is inserted into the positioning groove 24, and a roller shaft 15 is installed between the two positioning blocks 25. The positioning blocks 25 are adapted to the positioning groove 24. A dust-adhesive roller 22 is installed on the outer wall of the roller shaft 15. Slots 28 are provided inside the rotating shaft 20 and the roller shaft 15. A shaft 23 is inserted into the slot 28. One end of the shaft 23 extends through to the outside of the lifting frame 17 and is fitted with a pull plate 27. A threaded groove 26 is provided on the back of the lifting frame 17, and a threaded cap 21 is threadedly connected inside the threaded groove 26.

[0042] See Figures 1-8 A motor 19 is mounted on the outer surface of the lifting frame 17. The output end of the motor 19 is connected to a rotating shaft 20. When the motor 19 is working, it can drive the rotating shaft 20 to rotate. The rotating shaft 20 then drives the insert shaft 23 to rotate, which in turn drives the roller shaft 15 to rotate. The insert shaft 23 is adapted to the slot 28. The roller shaft 15 and the dust-adhesive roller 22 are detachably connected to the rotating shaft 20. The insert shaft 23 and the slot 28 are precisely adapted to ensure a tight and secure connection. At the same time, the roller shaft 15 and the dust-adhesive roller 22 can be detached from the rotating shaft 20. The back of the pull plate 27 is fitted against the inner wall of the threaded cover 21. The threaded cover 21 is made of ultra-high molecular weight polyethylene (UHMWPE) material. The outer wall of the threaded cover 21 is provided with anti-slip texture. The pull plate 27 is fitted against the inner wall of the threaded cover 21. After the threaded cover 21 is tightened, it can limit the insert shaft 23 to prevent axial movement. The anti-slip texture increases the friction of the hand, making it convenient for the operator to tighten the threaded cover 21.

[0043] See Figures 1-6 The roller conveyor 5 is equipped with a protective cover 6 on its top. The protective cover 6 has openings 7 on both sides. The protective cover 6 is made of polycarbonate material. The protective cover 6 can shield and protect the dust-sticking roller 22. The openings 7 provide a channel for the light guide plate to enter and exit, ensuring continuous conveying. The top of the protective cover 6 is equipped with a cover plate 9 by a hinge. The cover plate 9 can be opened and closed by the hinge, which is convenient for maintaining the internal dust-sticking roller 22. The top of the cover plate 9 is threadedly connected to a threaded rod 16. The bottom end of the threaded rod 16 is connected to a lifting frame 17 by a bearing. The rotation of the threaded rod 16 drives the lifting frame 17 to move up and down, adjusting the height of the dust-sticking roller 22. The roller conveyor 5 is equipped with a frame 3 on both sides. The frame 3 is equipped with a conveyor belt 4. The setting of the conveyor belt 4 can realize the feeding of the light guide plate to be cleaned and the feeding of the light guide plate after cleaning, forming a continuous production line.

[0044] See Figures 1-5One side of the protective cover 6 is equipped with a mounting base 10 and a support plate 14. An ion fan 11 is installed on one side of the mounting base 10. A diversion pipe 12 is fixed on one side of the support plate 14, and multiple ion nozzles 13 are installed at the bottom of the diversion pipe 12. The ion nozzles 13 are located directly above the conveyor belt 4, and the air inlet of the diversion pipe 12 is connected to the air outlet of the ion fan 11. The ion fan 11 generates ion air, which enters the ion nozzles 13 through the diversion pipe 12. The ion nozzles 13 blow air in a directional manner onto the light guide plate to neutralize surface static electricity and prevent static electricity from re-adsorbing dust. A control panel 2 is installed on the outer surface of the machine body 1. The control panel 2 is electrically connected to the conveyor belt 4, the roller conveyor 5, the ion fan 11, and the motor 19, respectively, so that the operator can start or stop the conveyor belt 4, the roller conveyor 5, the ion fan 11, and the motor 19 through the control panel 2.

[0045] Example 2:

[0046] Based on the above embodiment 1, the following structure will be set to improve the stability of the cover plate 9.

[0047] Specifically, a latch 8 is installed between the cover plate 9 and the protective cover 6. The latch 8 can ensure that the cover plate 9 is closed tightly, thereby improving the stability of the cover plate 9 after it is closed.

[0048] Example 3:

[0049] Based on the above embodiment 1, in order to improve the stability of the lifting frame 17 when it moves, it is necessary to guide the lifting frame 17, so the following structure will be set.

[0050] Specifically, guide rods 18 that penetrate the cover plate 9 are installed on both sides of the top of the lifting frame 17. The guide rods 18 restrict the tilt of the lifting frame 17, ensure smooth height adjustment, and improve the stability of the lifting frame 17 when it moves.

[0051] The working principle of this utility model is as follows: First, before use, the operator can turn on the power supply and set the parameters through the control panel 2: the conveying speed of the conveyor belt 4 and the roller conveyor 5 (e.g., 0.5m / s), the rotation speed of the motor 19 (e.g., 30r / min, matching the conveying speed), and the start / stop status of the ion fan 11.

[0052] Depending on the thickness of the light guide plate to be cleaned, the operator rotates the threaded rod 16, which drives the lifting frame 17 to move up and down along the guide rod 18, adjusting the height of the dust-adhesive roller 22 so that the dust-adhesive roller 22 contacts the surface of the light guide plate. Then the cover plate 9 is closed and locked by the latch 8 to form a cleaning space.

[0053] The light guide plate to be cleaned is conveyed to the roller conveyor 5 by the conveyor belt 4. At the same time, the control panel 2 controls the ion fan 11 to start. The ion air is distributed to multiple ion nozzles 13 through the diversion pipe 12. The ion nozzles 13 blow ion air directionally onto the surface of the light guide plate to neutralize the static electricity on the surface (to prevent static electricity from attracting dust). The roller conveyor 5 smoothly sends the light guide plate into the cleaning area inside the protective cover 6. The opening 7 is the light guide plate's entry and exit channel. Then, the motor 19 starts and drives the rotating shaft 20 connected to it to rotate. The rotating shaft 20, through the cooperation of the positioning groove 24 and the positioning block 25, drives the roller shaft 15 and the dust-adhesive roller 22 to rotate synchronously. The dust-adhesive roller 22 contacts the surface of the light guide plate and removes surface dust, particles and other contaminants during the rotation process to clean the light guide plate. The cleaned light guide plate is conveyed to the conveyor belt 4 on the other side by the roller conveyor 5.

[0054] When the surface of the sticky roller 22 is covered with dust, resulting in a decrease in cleaning effect (the operator can visually observe the adhesion of dust on the surface of the sticky roller 22 to determine whether the sticky roller 22 needs to be replaced), when replacing the sticky roller 22, the operator opens the latch 8, lifts the cover plate 9, unscrews the threaded cover 21 on the back of the lifting frame 17, pulls the pull plate 27 to remove the insert shaft 23, removes the roller shaft 15 and the sticky roller 22, and replaces the new sticky roller; inserts the positioning block 25 on the roller shaft 15 of the new sticky roller 22 into the positioning groove 24 of the rotating shaft 20, positions the roller shaft 15, and then inserts the insert shaft 23, screws on the threaded cover 21 to make it fit against the pull plate 27 so as to limit the pull plate 27 and the insert shaft 23, and then closes the cover plate 9 and locks it, and the equipment is put back into use.
