Description

Technical Field

[0001] The present invention relates to the technical field of panel laminating devices, and particularly to a panel laminating device for the production of LCD liquid crystal display screens. Background Art

[0002] With the continuous advancement of technology, more and more touch screen manufacturers have started to adopt advanced panel laminating devices to improve production efficiency and product quality. These panel laminating devices not only represent a leap in manufacturing technology but also greatly meet the growing market demand for high-definition, high-color saturation, and ultra-thin display screens. These advanced laminating devices achieve the lamination between liquid crystal panels and backlight modules or other key components through precise mechanical design and automation control technology.

[0003] Currently, for the panel laminating devices used in the production of LCD liquid crystal display screens, at least the following technical problems are found:

[0004] Traditional panel laminating methods often rely on manual operation or semi-automated equipment. Manual lamination is not only inefficient but also difficult to ensure the accuracy and consistency of lamination. Due to the limitations of manual operation, position deviation, uneven distribution of adhesives, etc. are likely to occur, thus affecting the quality and performance of the display screen.

[0005] Some existing semi-automated laminating equipment, although improving production efficiency to a certain extent, still has defects such as single function and poor flexibility. For example, some equipment cannot perform precise position correction on the substrate and the touch screen, resulting in large lamination errors; there are also some equipment whose loading and unloading processes are not smooth enough, affecting the overall production rhythm. Therefore, in order to improve the production quality and efficiency of LCD liquid crystal display screens and reduce production costs, it is particularly urgent to develop a new type of panel laminating device with high precision and high automation.

[0016] Beneficial effects

[0017] One: The correction component in the panel laminating device for LCD liquid crystal display production can finely correct the positions of the substrate and the touch screen, ensuring extremely high precision when the two are laminated.

At the bottom end of each round rod 45, a round block 46 is fixedly installed. The connecting rod 43 is fixedly connected to the round block 46 through two springs 47. In the middle of the peripheral surface of the correction seat 2, grooves 21 are opened. Each correction block 31 is movably arranged in the groove 21. Each correction block 31 is rotatably connected to the correction seat 2. The push rod 51 is of a U-shaped design. At both ends of the push rod 51, extension blocks 54 are fixedly installed. The surface of each extension block 54 is of an inclined surface design. A second threaded rod 24 is rotatably installed in the avoidance groove 22 on one side. A through rod 23 is fixedly installed in the other avoidance groove 22. The second threaded rod 24 penetrates through the end of one of the sliding rods 52 and is threadedly connected to the sliding rod 52. The through rod 23 movably penetrates through the other sliding rod 52. At the end of the bottom plate 1, a connecting plate 11 is fixedly installed. A moving member 6 movably penetrates through the connecting plate 11. One end of the moving member 6 is fixedly connected to a dispensing machine 61. The dispensing machine 61 is located above the push rod 51. A first threaded rod 15 is rotatably installed on the connecting plate 11. The first threaded rod 15 penetrates through the moving member 6 and is threadedly connected to the moving member 6. At both ends of the dispensing machine 61, limiting rods 12 are fixedly installed. Each limiting rod 12 movably penetrates through the connecting plate 11,For limiting the movement of the dispensing machine 61, a first motor for driving the rotation of the first placement frame 13 is fixedly installed on the connecting plate 11. The second threaded rod 24 and the through rod 23 are respectively rotatably connected and fixedly connected to the connecting plate 11. A second motor for driving the rotation of the second threaded rod 24 is fixedly installed on the connecting plate 11. A bracket 7 is fixedly installed at the upper end of the bottom plate 1. A sliding seat 8 is slidably installed on the bracket 7. A third threaded rod 71 is rotatably installed on the bracket 7. The third threaded rod 71 penetrates through the sliding seat 8 and is threadedly connected to the sliding seat 8. A third motor 72 for driving the rotation of the third threaded rod 71 is fixedly installed on the bracket 7. A connecting frame 9 is arranged on one side of the bottom plate 1. A conveyor belt 91 is arranged inside the connecting frame 9. A notch is formed on the surface of the connecting frame 9. A plurality of substrates and a plurality of touch screens are respectively stacked and placed in the first placement frame 13 and the second placement frame 14;

[0036] During use, first start the second motor to rotate the second threaded rod 24. Since the second threaded rod 24 is threadedly connected to the sliding rod 52, the sliding rod 52 moves along a specific direction under the rotation of the second threaded rod 24, thereby driving the push rod 51 to move together. During the movement of the sliding rod 52, the pushing block 53 fixed at its end also moves accordingly. The pushing block 53 applies a downward force to the contact block 44, causing the connecting rod 43 and the outer frame 41 to move downward along the direction of the round rod 45. When the outer frame 41 moves downward, the rack 42 fixedly installed on the outer frame 41 moves downward synchronously. The rack 42 meshes with the gear 33, and the downward movement of the rack 42 drives the gear 33 to rotate, causing the four correction blocks 31 to respectively flip outward around the connecting shaft 32 into the groove 21. At this time, the four correction blocks 31 are parallel to the surface of the correction seat 2, reaching the initial state. Then, start the third motor 72, and the third motor 72 drives the third threaded rod 71 to rotate. Since the sliding seat 8 is threadedly connected to the third threaded rod 71, the rotation of the third threaded rod 71 drives the sliding seat 8 to move along the bracket 7, accurately moving the vacuum suction cup 82 directly above the placement frame one 13. Then, start the electric telescopic rod 81, and the expansion and contraction of the electric telescopic rod 81 drives the vacuum suction cup 82 to move downward. At the same time, start the vacuum pump to evacuate the inside of the vacuum suction cup 82 to a vacuum state, use the vacuum adsorption force to suck the substrate in the placement frame one 13, and place it stably on the correction seat 2. After that, the second motor controls the second threaded rod 24 to reverse, driving the sliding rod 52, the push rod 51, and the pushing block 53 to move in the reverse direction. The downward force of the pushing block 53 on the contact block 44 disappears. Under the rebounding action of the spring 47, the connecting rod 43 and the outer frame 41 move upward, and the rack 42 rises accordingly, driving the gear 33 to rotate in the reverse direction, causing the four correction blocks 31 to flip perpendicular to the surface of the correction seat 2. At this time, the four correction blocks 31 are distributed around the substrate to accurately correct the position of the substrate, making it in the centered position of the correction seat 2. After the position correction is completed, start the first motor, and the first motor drives the first threaded rod 15 to rotate. Since the moving part 6 is threadedly connected to the first threaded rod 15, the rotation of the first threaded rod 15 drives the moving part 6 to move along a specific direction, thereby moving the dispensing machine 61 to a suitable position above the substrate and evenly spraying the adhesive on the surface of the substrate;

[0037] After the spraying of the adhesive is completed on the substrate surface, the dispenser 61 resets under the action of the first motor and the first threaded rod 15, and the four correction blocks 31 also reset under the control of the second motor and the second threaded rod 24. Then, the vacuum chuck 82 sucks the touch screen in the second placement frame 14 and moves it above the correction seat 2. Then, the electric telescopic rod 81 is driven to make the vacuum chuck 82 drive the touch screen to slowly move downward. When the touch screen moves downward to a certain distance from the substrate, the second motor controls the second threaded rod 24 to reverse again, driving the slide bar 52, the push rod 51 and the push block 53 to move, so that the contact block 44 receives a downward acting force, the outer frame 41 and the rack 42 move downward, driving the gear 33 to rotate, and the four correction blocks 31 are turned over again to be perpendicular to the surface of the correction seat 2 to correct the position of the touch screen to ensure that the touch screen is accurately located directly above the substrate. Subsequently, the four correction blocks 31 return to the initial state, and the electric telescopic rod 81 continues to drive the vacuum chuck 82 to move downward, so that the touch screen is closely attached to the substrate;

[0038] During the reverse rotation of the second threaded rod 24, the slide bar 52 and the push rod 51 continuously move closer to the correction seat 2. When the push block 53 is completely misaligned with the contact block 44, the bottom surface of the slide bar 52 fits with the upper surface of the contact block 44. At this time, the continuous movement of the slide bar 52 and the push rod 51 will no longer apply a downward acting force to the contact block 44, and the outer frame 41 and the rack 42 are maintained in a balanced state under the pulling force of the spring 47. Such a design avoids unnecessary movement interference and ensures the rationality and stability of the overall structural design. The push rod 51 continues to move, and the push block 53 at its end smoothly pushes the touch screen and the substrate after fitting from the notch of the connecting frame 9 onto the conveyor belt 91, thus completing the function of automatic blanking. The conveyor belt 91 continuously operates to convey the fitted products to the next process;

[0039] After the pushing of the fitted touch screen and substrate is completed, the second motor controls the second threaded rod 24 to rotate forward. Under the forward rotation of the second threaded rod 24, the slide bar 52 and the push rod 51 reset along the opposite direction of the initial movement. The through rod 23 movably penetrates the slide bar 52, playing an accurate guiding and limiting role in the movement of the push rod 51 and the slide bar 52 to ensure the accuracy and stability of their movement paths. The round rod 45 movably penetrates the connecting rod 43, playing an effective limiting role in the movement of the outer frame 41, the rack 42 and the connecting rod 43 to prevent their position offsets during the movement, so as to ensure that the rack 42 can stably drive the gear 33, the connecting shaft 32 and the correction block 31 to rotate. The spring 47 plays a role in resetting the connecting rod 43 and the outer frame 41 in this process, preparing for the next correction operation;

[0040] The push rod 51 adopts a U-shaped design with the opening facing the correction seat 2. Extension blocks 54 are fixedly installed at both ends of the push rod 51. The opposite surfaces of the two extension blocks 54 are both bevel-designed. This structure makes the opening of the push rod 51 larger. When pushing the assembled product, the larger opening and bevel design can make contact with the product more smoothly, increase the contact area, reduce the unstable pushing or product deviation caused by small or uneven contact area, and further improve the reliability and stability of the blanking operation.

[0041] Working principle:

[0042] First step, during use, first start the second motor to make the second threaded rod 24 rotate. Since the second threaded rod 24 is threadedly connected to the sliding rod 52, the sliding rod 52 moves along a specific direction under the rotation of the second threaded rod 24, thereby driving the push rod 51 to move together. During the movement of the sliding rod 52, the pushing block 53 fixed at its end also moves accordingly. The pushing block 53 exerts a downward force on the contact block 44, causing the connecting rod 43 and the outer frame 41 to move downward along the direction of the round rod 45. When the outer frame 41 moves downward, the rack 42 fixedly installed on the outer frame 41 moves downward synchronously. The rack 42 meshes with the gear 33, and the downward movement of the rack 42 drives the gear 33 to rotate, causing the four correction blocks 31 to respectively flip outward around the connecting shaft 32 into the groove 21. At this time, the four correction blocks 31 are parallel to the surface of the correction seat 2, reaching the initial state. Then, start the third motor 72. The third motor 72 drives the third threaded rod 71 to rotate. Since the sliding seat 8 is threadedly connected to the third threaded rod 71, the rotation of the third threaded rod 71 drives the sliding seat 8 to move along the bracket 7, accurately moving the vacuum suction cup 82 directly above the placement frame 13. Then, start the electric telescopic rod 81. The expansion and contraction of the electric telescopic rod 81 drives the vacuum suction cup 82 to move downward. At the same time, start the vacuum pump to evacuate the inside of the vacuum suction cup 82 to a vacuum state, and use the vacuum adsorption force to suck the substrate in the placement frame 13 and place it smoothly on the correction seat 2. After that, the second motor controls the second threaded rod 24 to reverse, driving the sliding rod 52, the push rod 51, and the pushing block 53 to move in the reverse direction. The downward force of the pushing block 53 on the contact block 44 disappears. Under the rebound effect of the spring 47, the connecting rod 43 and the outer frame 41 move upward, and the rack 42 rises accordingly, driving the gear 33 to rotate in the reverse direction, causing the four correction blocks 31 to flip perpendicular to the surface of the correction seat 2. At this time, the four correction blocks 31 are distributed around the substrate to accurately correct the position of the substrate, making it in the centered position of the correction seat 2. After the position correction is completed, start the first motor. The first motor drives the first threaded rod 15 to rotate. Since the moving part 6 is threadedly connected to the first threaded rod 15, the rotation of the first threaded rod 15 drives the moving part 6 to move along a specific direction, so that the dispensing machine 61 moves to a suitable position above the substrate to evenly spray the adhesive on the surface of the substrate;

[0043] In the second step, after the adhesive is sprayed on the surface of the substrate, the dispensing machine 61 resets under the action of the first motor and the first threaded rod 15, and the four alignment blocks 31 also reset under the control of the second motor and the second threaded rod 24. Then, the vacuum chuck 82 sucks the touch screen in the second placement frame 14 and moves it above the alignment seat 2. Then, the electric telescopic rod 81 is driven to make the vacuum chuck 82 drive the touch screen to slowly move down. When the touch screen moves down to a certain distance from the substrate, the second motor controls the second threaded rod 24 to reverse again, driving the sliding rod 52, the push rod 51 and the push block 53 to move, so that the contact block 44 receives a downward force, and the outer frame 41 and the rack 42 move down, driving the gear 33 to rotate. The four alignment blocks 31 are flipped again to be perpendicular to the surface of the alignment seat 2 to correct the position of the touch screen, ensuring that the touch screen is accurately located directly above the substrate. Subsequently, the four alignment blocks 31 return to the initial state, and the electric telescopic rod 81 continues to drive the vacuum chuck 82 to move down, making the touch screen closely fit with the substrate;

[0044] In the third step, during the reverse rotation of the second threaded rod 24, the sliding rod 52 and the push rod 51 continuously move closer to the alignment seat 2. When the push block 53 is completely misaligned with the contact block 44, the bottom surface of the sliding rod 52 fits with the upper surface of the contact block 44. At this time, the continuous movement of the sliding rod 52 and the push rod 51 will no longer apply a downward force to the contact block 44, and the outer frame 41 and the rack 42 are maintained in a balanced state under the pulling force of the spring 47. Such a design avoids unnecessary movement interference and ensures the rationality and stability of the overall structural design. The push rod 51 continues to move, and the push block 53 at its end smoothly pushes the touch screen and the substrate after fitting from the notch of the connecting frame 9 onto the conveyor belt 91, thus completing the function of automatic blanking. The conveyor belt 91 continuously operates to convey the fitted products to the next process;

[0045] In the fourth step, after the touch screen and the substrate after fitting are pushed, the second motor controls the second threaded rod 24 to rotate forward. Under the forward rotation of the second threaded rod 24, the sliding rod 52 and the push rod 51 reset along the opposite direction of the initial movement. The through rod 23 movably penetrates the sliding rod 52, playing an accurate guiding and limiting role in the movement of the push rod 51 and the sliding rod 52 to ensure the accuracy and stability of their movement paths. The round rod 45 movably penetrates the connecting rod 43, playing an effective limiting role in the movement of the outer frame 41, the rack 42 and the connecting rod 43 to prevent their position offsets during the movement, so as to ensure that the rack 42 can stably drive the gear 33, the connecting shaft 32 and the alignment block 31 to rotate. The spring 47 plays a role in resetting the connecting rod 43 and the outer frame 41 in this process, preparing for the next alignment operation;

[0046] In the fifth step, the push rod 51 is designed in a U shape with the opening facing the correction seat 2. Extension blocks 54 are fixedly installed at both ends of the push rod 51. The two opposite surfaces of the two extension blocks 54 are designed as inclined surfaces. This structure makes the opening of the push rod 51 larger. When pushing the assembled product, the larger opening and the inclined surface design can contact the product more smoothly, increase the contact area, and reduce the unstable pushing or product deviation caused by a small or uneven contact area, further improving the reliability and stability of the blanking operation.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
