Description

Technical Field

[0001] This invention belongs to the field of bonding equipment technology, specifically relating to a light guide plate bonding device and method that can enhance the atomized display effect. Background Technology

[0002] A light guide plate is an important component used in LED backlights. Its function is to evenly distribute point or line light sources onto the display screen, improving the fogging display effect. Light guide plate bonding equipment is a specialized device used to bond light guide plates with other materials (such as protective films, reflective films, etc.). This type of equipment plays a crucial role in the production and processing of light guide plates, ensuring a tight bond between the light guide plate and other components, thereby improving the overall product quality and performance.

[0003] For example, the light guide plate suction cup transfer device with supplementary film application function disclosed in patent publication number CN112499249B includes a main body, with an intelligent robotic arm fixedly connected to the upper end face of the main body. The main body has two corresponding movable cavities that are symmetrical to each other and open downwards. The openings of the corresponding movable cavities face outwards, and movable slides are slidably connected between the front and rear end walls of the corresponding movable cavities. A corresponding belt cavity extending upwards is provided between the left and right corresponding movable cavities. By making the suction cup tightly adhere to the uncoated area of ​​the light guide plate, the automatic transfer of the light guide plate is realized, minimizing the possibility of deformation and damage to the light guide plate during the transfer process. The squeezing block drives the corresponding protective film to move downwards to contact the uncoated area of ​​the light guide plate, thereby realizing the supplementary film application to the uncoated area of ​​the light guide plate, and protecting the light guide plate as much as possible while facilitating the transfer of the light guide plate.

[0004] However, traditional devices still have the following problems when in use:

[0005] The back side of the light guide plate's coated surface is the laser dot surface of the light guide plate. This side needs to be transferred and bonded to the dot surface of the light guide plate using the same suction cup transfer device. However, the actual contact point between the two is only the suction position of the suction cup, and the bonding is achieved solely through the pressure of the suction cup. This method easily leads to uneven pressure on the reflector, resulting in an uneven display effect of the atomized dots after bonding, which may affect the pass rate. Therefore, existing mechanisms usually reduce the pressing pressure at the suction cup to pursue a more balanced visual effect of the dots. However, this results in lighter pressure, further leading to a less tight bond between the products. The illuminated display effect has clear dots but a strong grainy texture. This device needs to be optimized. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a light guide plate bonding device and method that can enhance the atomized display effect. This device and method have the advantages of adjusting the bonding pressure between the light guide plate and the reflector, thereby reducing the visual graininess of the light guide plate and enhancing the atomized display effect.

[0016] Preferably, a method for bonding a light guide plate to enhance the atomized display effect is characterized by including a light guide plate bonding device for enhancing the atomized display effect as described in any one of the above-mentioned inventions, wherein the bonding method is as follows:

[0017] Step 1: The reflector is transported by the conveyor belt, and the light guide plate is transported by the second conveyor frame. The central control console uses a visual communication sensor to visually monitor the specific positions of the light guide plate and the reflector, and then intelligently adjusts the horizontal guide rail, vertical guide rail and telescopic frame to press the pneumatic plate down to the position of the light guide plate.

[0019] Step 3: Air pressure is transmitted through the electronically controlled air valve to the electromagnetic regulating valve, blowing air into the movable chamber. This directly drives the fan plate to rotate, generating wind. The wind force mixes with the air pressure from the electronically controlled air valve and is blown out through the connecting chamber, applying pressure to the rotating rod and reinforcing the fit between the rotating rod and the conveyor belt.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In this invention, a reflector is transported via a conveyor belt, and a light guide plate is transported via a second conveyor frame. The central control console uses a visual communication sensor to monitor the specific positions of the light guide plate and reflector, and then intelligently adjusts the horizontal and vertical guide rails and the telescopic frame to press the pneumatic plate down to the position of the light guide plate. A signal transmission activates the central control console to extract air, using multiple suction ports to adhere to the top outer wall of the light guide plate, lifting it up and then moving it to the top outer wall of the reflector to complete the adhesion. This protects the light guide plate and reduces the grainy texture of the dots. Furthermore, an electrically controlled air valve transmits air pressure to an electromagnetic regulating valve, blowing air into the movable chamber, which directly drives the fan plate to rotate, generating wind. The wind force mixes with the air pressure from the electrically controlled air valve and flows through the connecting cavity. As the air pressure plate adsorbs the rotating rod and moves towards the conveyor belt, the air outlet in the connecting cavity first blows onto the outer wall of the conveyor belt, removing any dust or impurities that may be attached to the belt. This ensures the cleanliness of the conveyor belt surface, preventing visual particle stains caused by dust and avoiding visual dot particles caused by air bubbles due to dust obstructing the tight fit. This further reduces the dot particle effect and enhances the fogging display effect. At the same time, after the rotating rod and conveyor belt are bonded, as the air pressure plate moves back, the air outlet in the connecting cavity passes over the surface of the rotating rod and applies pressure to the rotating rod through the blowing air pressure, reinforcing the bond between the rotating rod and the conveyor belt. This further reduces the dot particle effect and enhances the fogging display effect. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figures 1 to 13This invention provides a technical solution: a light guide plate bonding device that can enhance the atomization display effect, comprising a frame 1, a vertical guide rail 4 fixedly connected to the top outer wall of the frame 1, a telescopic frame 5 slidably connected to the outer wall of the vertical guide rail 4, a telescopic rod 6 fixedly installed on the axis of the telescopic frame 5, a support frame 7 fixedly connected to the bottom outer wall of the telescopic rod 6, an air pressure plate 8 fixedly connected to the bottom of the support frame 7, multiple air inlets 9 fixedly installed on the bottom outer wall of the air pressure plate 8, rubber gaskets 10 fixedly connected to the bottom outer wall of the air inlets 9, an electrically controlled air valve 11 fixedly connected to the top outer wall of the frame 1, multiple air supply pipes fixedly connected to the output end of the electrically controlled air valve 11, an air inlet 12 fixedly connected to one side outer wall of the air pressure plate 8, wherein the outer wall of two air supply pipes away from the electrically controlled air valve 11 is connected to the air pressure plate 8 through the air inlet 12, and a central control console 46 fixedly connected to the top outer wall of the frame 1, the electrically controlled air valve 11 being connected to the central control console 46. The signal connection of the platform 46 is as follows: the top outer wall of the frame 1 is fixedly connected to the first conveyor frame 37, the inner wall of the first conveyor frame 37 is rotatably connected to multiple rotating rods 38, the outer wall of the multiple rotating rods 38 is sleeved with two conveyor belts 39, the top outer wall of the conveyor belts 39 is movably placed with a reflector plate 49, the top outer wall of the frame 1 is also fixedly connected to the second conveyor frame 47, the top outer wall of the second conveyor frame 47 is movably placed with a release paper (53), the surface of the release paper (53) is covered with a light guide plate 48, the top outer wall of 1 is fixedly connected to 2, the top interior of the lighting frame 2 is fixedly installed with a visual communication sensor 50, the interior of the support frame 7 is provided with a movable cavity 15, the bottom inner wall of the movable cavity 15 is rotatably connected to a central shaft rotating rod 16, the outer walls of the central shaft rotating rod 16 are fixedly connected to fan plates 17, one side outer wall of the support frame 7 is fixedly connected to a connecting plate 21, the inner wall of the connecting plate 21 is provided with a connecting cavity 22 that communicates with the movable cavity 15.

[0038] In this invention, the reflector plate 49 is transported by the conveyor belt 39, and the light guide plate 48 is transported by the second conveyor frame 47. The central control console 46 uses the visual communication sensor 50 to visually monitor the specific positions of the light guide plate 48 and the reflector plate 49, and then intelligently adjusts the horizontal guide rail 3, the vertical guide rail 4, and the telescopic frame 5 to press the air pressure plate 8 down to the position of the light guide plate 48. The central control console 46 is activated to extract air through signal transmission, and multiple air intakes 9 are used to adsorb the top outer wall of the light guide plate 48, lifting the light guide plate 48, and then moving it to the top outer wall of the reflector plate 49 to complete the bonding, thereby protecting the light guide plate 48 and reducing the graininess of the dots. The release paper 53 will be gradually collected into the frame (1) by the conveyor belt 39. In addition, the air pressure is transmitted to the electromagnetic regulating valve 13 through the electrically controlled air valve 11 to blow air into the active cavity 15, which will directly drive the fan plate 17 to rotate and generate wind. The air pressure from the wind-powered mixed-electric air valve 11 is blown out through the connecting cavity 22. When the air pressure plate 8 moves from the light guide plate 48 to the reflector plate 49, the air outlet of the connecting cavity 22 first blows onto the outer wall of the reflector plate 49, removing any dust or impurities that may be attached to the reflector plate 49. This ensures the cleanliness of the reflector plate 49 surface, thus avoiding visual particle stains caused by dust and preventing visual dot particles caused by air bubbles due to dust obstructing the tight bonding. This further reduces the dot particle effect and enhances the fogging display effect. At the same time, when the light guide plate 48 and the reflector plate 49 are bonded and the air pressure plate 8 moves back, the air outlet of the connecting cavity 22 passes over the surface of the light guide plate 48 and applies pressure to the light guide plate 48 through the blowing air pressure, reinforcing the bonding between the light guide plate 48 and the reflector plate 49, thereby further reducing the dot particle effect and enhancing the fogging display effect.

[0039] In Example 2, based on Example 1, an electromagnetic regulating valve 13 connected to the movable cavity 15 is fixedly installed on one outer wall of the support frame 7. An air outlet 14 is fixedly connected to one outer wall of the electromagnetic regulating valve 13. Part of the air supply pipe of the electrically controlled air valve 11 is connected to the electromagnetic regulating valve 13 through the air outlet 14. Multiple mounting plates 24 are fixedly installed on the inner wall of the connecting cavity 22. A connecting hole 25 with two sides is opened on the outer wall of the mounting plate 24. A limit rod 23 is fixedly connected to the inner wall of the connecting cavity 22. The inner wall of the connecting hole 25 is movably sleeved with the outer wall of the limit rod 23. A pressing roller 26 is rotatably connected to the bottom outer wall of the mounting plate 24. An extension plate 27 is fixedly connected to one outer wall of the mounting plate 24.

[0040] In this invention, after the light guide plate 48 and the reflector plate 49 are bonded together, when the air outlet of the connecting cavity 22 moves back across the surface of the light guide plate 48, the pressing roller 26 moves and is attached to the surface of the light guide plate 48, thereby applying pressure to the light guide plate 48, further reducing the graininess of the dots and enhancing the fogging display effect. At the same time, when the airflow blown out of the active cavity 15 passes through the connecting cavity 22, it will drive the extension plate 27 to rotate slightly. The extension plate 27 deflects around the limiting rod 23 as the axis, causing the pressing roller 26 to vibrate, thereby increasing the active area of ​​the pressing roller 26 on the surface of the light guide plate 48, further improving the pressure effect of the pressing roller 26, reducing the graininess of the dots, and enhancing the fogging display effect.

[0041] In Example 3, based on Example 2, an insert plate 18 is fixedly connected to the outer wall of the fan plate 17, and an adjusting plate 19 is slidably connected to the inner wall of the insert plate 18. A first reset spring 20 is provided inside the insert plate 18. One end of the outer wall of the first reset spring 20 is fixedly connected to one end of the outer wall of the fan plate 17, and the end of the first reset spring 20 away from the fan plate 17 is fixedly connected to one end of the outer wall of the adjusting plate 19. A magnet block 29 is fixedly connected to the outer wall of the adjusting plate 19 away from the fan plate 17, and the outer wall of the magnet block 29 is slidably connected to the inner wall of the movable cavity 15. A magnet block 28 is fixedly connected to the outer wall of the extension plate 27 away from the mounting plate 24, and the magnet block 28 is magnetically connected to the magnet block 29.

[0042] In this invention, the sliding connection between the adjusting plate 19 and the insert plate 18 allows the distance between the fan plate 17 and the adjusting plate 19 to be freely adjusted at all times. When the fan plate 17 rotates, the first magnet 29 will abut against one end of the outer wall of the output port of the active cavity 15. As the fan plate 17 continues to rotate, the adjusting plate 19 will be pressed back into the insert plate 18, thus ensuring that the first magnet 29 always slides to the other end of the outer wall while in contact with the output port of the active cavity 15. This contact method allows the first magnet 29 to generate a magnetic attraction to the second magnet 28. The continuous high-frequency rotation of multiple first magnets 29 will cause the second magnet 28 to produce a small-amplitude reciprocating polarization oscillation effect. This oscillation effect further drives the pressing roller 26 to vibrate, thereby increasing the active area of ​​the surface of the pressing roller 26 with the rotating rod 38, further improving the pressing effect of the pressing roller 26, reducing the graininess of the dots, and enhancing the atomization display effect.

[0043] In Example 4, based on Example 3, a liquid storage tank 32 is fixedly connected to the top outer wall of the support frame 7. A slide rail 33 is fixedly installed on the bottom outer wall of the liquid storage tank 32, passing through the inner wall of the support frame 7. A magnet block 34 is slidably connected to the inner wall of the slide rail 33. The magnet block 34 has a discharge hole 35 that communicates with its upper and lower ends. A second return spring 36 is fixedly connected to the outer wall of one end of the discharge hole 35. One side of the outer wall of the second return spring 36 is fixedly connected to the inner wall of the slide rail 33. A slot 31 that communicates with the interior is opened on the top outer wall of the insert plate 18. The slide rail 33 is located in the slot 31. On the upper side, a magnet 4 52 is fixedly connected to the outer wall of the top side of the adjusting plate 19. The magnet 4 52 is magnetically connected to the magnet 34. When the magnet 34 is magnetically stretched away from the end of the second reset spring 36, the magnet 34 is connected to the output port of the storage tank 32. A plurality of storage sponges 30 are fixedly connected to one side of the outer wall of the adjusting plate 19 below the magnet 34. The outer wall of the adjusting plate 19 is provided with a guide groove 51 with an inclined angle downward. A plurality of storage sponges 30 are fixedly connected to one side of the outer wall of the adjusting plate 19 below the guide groove 51.

[0044] In this invention, when the adjusting plate 19 is pressed back into the insert plate 18, the magnet block 52, which is fixedly connected to the adjusting plate 19, will move synchronously and move out of the slot 31. When the support frame 7 moves back after attaching the reflector plate 49, the electromagnetic regulating valve 13 stops supplying air, and the rotation speed of the fan plate 17 gradually slows down. At this time, when the insert plate 18 passes through the slot 31 and passes the bottom of the liquid storage tank 32, the magnet block 52 will generate magnetic attraction to attract the magnet block 34 to move laterally, so that the discharge hole 35 coincides with the liquid inlet of the liquid storage tank 32 and connects. The lubricating oil loaded in the liquid storage tank 32 flows through the outlet. The lubricant drips layer by layer through the discharge hole 35 onto the storage sponge 30 below. The rotation speed of the fan plate 17 gradually slows down, so the frequency of lubricant addition is not too high, avoiding excessive flow of lubricant. The storage sponge 30 absorbs and stores the lubricant, and with the centrifugal force of the subsequent rotation of the fan plate 17, some of the lubricant seeping out of the storage sponge 30 is guided along the oblique direction of the guide groove 51 to flow layer by layer to the contact position of the adjusting plate 19 and the insert plate 18, thereby reducing the friction between the insert plate 18 and the adjusting plate 19. This device can effectively ensure the retention of lubricant.

[0045] In Example 5, based on Example 1, an air intake bracket 40 is fixedly installed on the inner wall of the first conveyor frame 37. One end of the air supply pipe of the electrically controlled air valve 11 passes through the first conveyor frame 37 and is connected to the inner wall of the air intake bracket 40. A first air pressure holding bracket 41 is fixedly connected to the output end of the air intake bracket 40. A folded plastic plate 42 is fixedly connected to the top outer wall of the first air pressure holding bracket 41. A second air pressure holding bracket 43 is fixedly connected to the top outer wall of the folded plastic plate 42. An air pressure holding rod 44 is fixedly connected to the top outer wall of the first air pressure holding bracket 41. The top outer wall of the air pressure holding rod 44 is fixedly connected to the bottom outer wall of the second air pressure holding bracket 43. An air pressure flow pipe 45 is fixedly connected to one side outer wall of the first air pressure holding bracket 41.

[0046] When the reflector 49 is moved to the second pneumatic retainer 43 by the conveyor belt 39, the air intake bracket 40 is evacuated by the electrically controlled air valve 11 so that the second pneumatic retainer 43 can tightly adhere to the reflector 49, thereby preventing the reflector 49 from shifting when the pressing roller 26 rolls.

[0047] The working principle and usage process of the present invention: In the present invention, the reflector plate 49 is transported by the conveyor belt 39, and the light guide plate 48 is transported by the second conveyor frame 47. The central control console 46 uses the visual communication sensor 50 to visually monitor the specific positions of the light guide plate 48 and the reflector plate 49, and then intelligently adjusts the horizontal guide rail 3, the vertical guide rail 4 and the telescopic frame 5 to press the air pressure plate 8 down to the position of the light guide plate 48. The central control console 46 is activated to extract air through signal transmission, and multiple air suction ports 9 are used to adsorb the top outer wall of the light guide plate 48, and the light guide plate 48 is sucked up and then moved to the top outer wall of the reflector plate 49 to complete the bonding, thereby protecting the light guide plate 48 and reducing the graininess of the dots. The release paper 53 will be gradually collected into the frame (1) by the conveyor belt 39. Furthermore, the air pressure transmitted through the electrically controlled air valve 11 to the electromagnetic regulating valve 13 blows air into the movable cavity 15, which directly drives the fan plate 17 to rotate and generate wind. The wind force mixes with the air pressure of the electrically controlled air valve 11 and is blown out through the connecting cavity 22. When the air pressure plate 8 adsorbs the light guide plate 48 and moves towards the conveyor belt 39, the air outlet of the connecting cavity 22 will first blow onto the outer wall of the surface of the conveyor belt 39, blowing away any dust and impurities that may be attached to the conveyor belt 39, ensuring the surface cleanliness of the conveyor belt 39. This avoids visual particle stains caused by dust and avoids visual dot particles caused by air bubbles due to dust obstructing the tight bonding, thereby further reducing the dot particle effect and enhancing the fogging display effect. At the same time, after the light guide plate 48 and the conveyor belt 39 are bonded together... When the air pressure plate 8 moves back, the air outlet of the connecting cavity 22 passes over the surface of the light guide plate 48. The air pressure applies pressure to the light guide plate 48, strengthening the adhesion between the light guide plate 48 and the conveyor belt 39, thereby further reducing the graininess of the dots and enhancing the fogging display effect. In this invention, when the rotating rod 38 and the conveyor belt 39 are attached, and the air outlet of the connecting cavity 22 moves back over the surface of the rotating rod 38, the pressing roller 26 moves and adheres to the surface of the rotating rod 38, thereby applying pressure to the rotating rod 38, further reducing the graininess of the dots and enhancing the fogging display effect. At the same time, the airflow blown out of the movable cavity 15, after passing through the connecting cavity 22, will drive the extension plate 27 to slightly polarize and fan. The extension plate 27 rotates around the limiting rod 23 as the axis. The deflection causes the pressing roller 26 to vibrate, thereby increasing the active area of ​​the pressing roller 26 with the rotating rod 38, further improving the pressure effect of the pressing roller 26, reducing the graininess of the dots, and enhancing the atomized display effect. In this invention, the sliding connection between the adjusting plate 19 and the insert plate 18 allows the distance between the fan plate 17 and the adjusting plate 19 to be freely adjusted at all times. When the fan plate 17 rotates, the first magnet 29 will abut against one end of the outer wall of the output port of the active cavity 15. As the fan plate 17 continues to rotate, the adjusting plate 19 will be pressed back into the insert plate 18, thus ensuring that the first magnet 29 always slides to the other end of the outer wall while in contact with the output port of the active cavity 15. This contact method allows the first magnet 29 to generate a magnetic attraction to the second magnet 28.The continuous high-frequency rotation of multiple magnet blocks 29 causes magnet block 28 to produce a small-amplitude reciprocating polarization oscillation effect. This oscillation effect further drives the pressing roller 26 to vibrate, thereby increasing the active area of ​​the pressing roller 26 with the rotating rod 38, further improving the pressure effect of the pressing roller 26, reducing the graininess of the dots, and enhancing the atomization display effect. In this invention, when the adjusting plate 19 is pressed back into the insert plate 18, the magnet block 52 fixedly connected to the adjusting plate 19 will move synchronously and move out of the slot 31. When the support frame 7 moves back after attaching the reflector plate 49, the electromagnetic regulating valve 13 stops supplying air, and the rotation speed of the fan plate 17 gradually slows down. At this time, when the insert plate 18 passes through the slot 31 and passes the bottom of the liquid storage tank 32, the magnet block 52 will generate magnetic attraction to attract the magnet block 34 to move laterally, thereby making the discharge hole 35 coincide with the inlet of the liquid storage tank 32 and connect. The lubricating oil in the storage tank 32 drips layer by layer through the discharge hole 35 onto the storage sponge 30 below. The gradually decreasing rotation speed of the fan plate 17 prevents excessive lubricating oil addition, avoiding excessive leakage. The storage sponge 30 absorbs and stores the lubricating oil, and with the subsequent rotation of the fan plate 17, centrifugal force guides some of the lubricating oil seeping from the sponge 30 along the guide groove 51, flowing layer by layer towards the contact position of the adjusting plate 19 and the insert plate 18, thereby reducing the friction between the insert plate 18 and the adjusting plate 19. This device effectively ensures the retention of lubricating oil. When the reflector plate 49 is moved to the second pneumatic retainer 43 via the conveyor belt 39, the air intake bracket 40 is evacuated by the electrically controlled air valve 11, allowing the second pneumatic retainer 43 to tightly adhere to the reflector plate 49, thus preventing the reflector plate 49 from shifting when the pressing roller 26 rolls.
