Liquid crystal display substrates need to undergo a series of processing from production to commissioning. Lamination is an important link in the production process of liquid crystal display substrates, so a lamination device is needed to bond the liquid crystal substrate to the display panel.

DETAILED DESCRIPTION

[0034] like Figure 1-Figure 7 As shown, the present invention provides a technical solution: a panel bonding device for liquid crystal display production, comprising a placing plate 1 and a driving wheel 2, a supporting leg 3 is fixed to the bottom surface of the placing plate 1, the supporting leg 3 and the side wall of the driving wheel 2 are rotatably connected, a shell 4 is fixed to the upper surface of the placing plate 1, a cylinder 5 is fixed to the upper surface of the shell 4, the piston of the cylinder 5 is connected to a piston rod, a suction cup 6 is fixed to the bottom end of the piston rod, a conveyor belt 7 is meshed with the outer wall of the driving wheel 2, a liquid crystal display substrate is placed on the conveyor belt 7, the driving wheel 2 starts to rotate, and the friction with the conveyor belt 7 drives it to slide, so that the liquid crystal display substrate moves to the center position, the shell 4 is provided with a positioning device 8 for convenient loading and auxiliary positioning and clamping, the placing plate 1 is provided with an auxiliary device 9 for conveniently lifting the liquid crystal display substrate to reduce friction and further assist the bonding work, and the shell 4 is provided with a processing device 10 for removing bubbles and assisting the glue to dry.

[0035] The positioning device 8 is mainly composed of a loading plate 81, a first saw blade 82, a first gear 83, a saw plate 84 and a clamping plate 85. The loading plate 81 penetrates the side wall of the shell 4 horizontally and is slidably connected at the penetration point. A panel coated with glue is placed in the groove of the loading plate 81. With the help of controlling the cylinder 5, the suction cup 6 is pressed downward to perform the loading operation. After the loading is completed, the suction cup 6 rises and then the loading plate 81 is pulled out. The first saw blade 82 penetrates the side wall of the shell 4 and is slidably connected at the penetration point. The first saw blade 82 and the side wall of the loading plate 81 are fixedly connected to each other. When the subsequent loading plate 81 is pulled out, the pulling out action of the loading plate 81 will drive the first saw blade 82 to slide. A first gear 83 is also penetrated in the side wall of the shell 4, and the penetration point is rotatably connected. The first saw blade 82 and the first gear 83 are meshed with each other. The sliding of the first saw blade 82 will prompt the first gear 8 3 rotates, a saw plate 84 penetrates the side wall of the shell 4, and the penetration is slidably connected, the first gear 83 and the saw plate 84 are meshed with each other, the rotation of the first gear 83 drives the saw plate 84 to slide, and a clamping plate 85 is fixed on the side wall of the saw plate 84, and the sliding of the saw plate 84 drives the clamping plate 85 to slide toward the center direction. When the clamping plate 85 slides to the specified position, it can prevent the LCD display substrate from continuing to move with the conveyor belt 7, and in this process, the positioning and clamping functions of the LCD display substrate are achieved. The positioning device 8 can directly load the material by controlling the cylinder 5. Compared with the traditional manual loading method, it can save a lot of time and manpower, and after the loading is completed, by pulling out the loading plate 81, it can simultaneously drive the clamping plate 85 to clamp and position the LCD display substrate, which is more beneficial to the subsequent bonding work and can effectively avoid the occurrence of undesirable conditions such as skewed bonding.

[0036] The auxiliary device 9 comprises a guide rod 91, a connecting rod 92, a hinge rod 93, a hinge block 94, a push plate 95 and a telescopic rod 96. The guide rod 91 passes through the side wall of the housing 4 horizontally and is slidably connected at the penetration point. The side wall of the clamping plate 85 is tightly fixedly connected to the guide rod 91. When the clamping plate 85 slides, due to the existence of the guide rod 91, it can only slide along the predetermined direction of the guide rod 91, effectively eliminating the possible swinging condition. In addition, when the clamping plate 85 slides, it will apply a horizontal driving force to the guide rod 91, causing the guide rod 91 to slide accordingly. A connecting rod 92 is fixed to the bottom surface of the rod 91, and the guide rod 91 slides to drive the connecting rod 92 connected thereto to move together. At this time, the left and right groups of connecting rods 92 gradually approach each other under the drive of the guide rod 91, and the end of the connecting rod 92 away from the guide rod 91 is connected to the hinge rod 93 by a hinged manner. As the connecting rods 92 approach each other, the hinge rod 93 will be pulled to rotate around the hinge point. In the process of the left and right groups of hinged rods 93 constantly approaching each other, the straight-line distance between them continues to shorten, and accordingly, the angle between the two groups of hinged rods 93 continues to decrease. The hinge point will gradually rise during this dynamic change process, and the end of the hinge rod 93 away from the connecting rod 92 is hinged to the hinge block 94. A push plate 95 is fixed to the upper end of the hinge block 94, so the upward movement of the hinge block 94 will further push the push plate 95 to move vertically upward. A telescopic rod 96 is fixed to the bottom surface of the push plate 95, and the end of the telescopic rod 96 away from the push plate 95 is fixedly connected to the bottom surface of the inner wall of the placement plate 1. During the entire process of the push plate 95 moving upward, the push plate 95 can always maintain a stable horizontal state due to the stable support and restriction of the telescopic rod 96. There will be no tilting phenomenon. Finally, the push plate 95 moves upward and lifts up the LCD display substrate placed above it. The auxiliary device 9 can lift up the LCD display substrate while clamping the LCD display substrate. In this way, the LCD display substrate can be prevented from continuously rubbing against the conveyor belt 7, thereby reducing the loss of the LCD display substrate. Moreover, when the panel is being bonded, an upward thrust can be applied from the bottom of the LCD display substrate, so that the panel and the LCD display substrate are bonded more firmly, which greatly improves the bonding quality and production efficiency of the product.

[0037] The processing device 10 is mainly composed of a limit block 101, a screw rod 102, a slider 103, a sponge 104, a second gear 105, a second saw blade 106, a third gear 107, a rotating shaft 108 and a fan blade 109. The limit block 101 is firmly fixed to the back of the shell 4, and a screw rod 102 is horizontally penetrated in the limit block 101, and the penetration is rotatably connected. A slider 103 is fixed on the side wall of the clamp plate 85. When the left clamp plate 85 starts to slide, the slider 103 will be linked to produce a corresponding displacement change. The screw rod 102 penetrates the slider 103 longitudinally, and the penetration is a threaded connection. When the slider 103 is displaced, the screw rod 102 is driven around its axis The center of the screw rod 102 rotates, and a sponge 104 is fixed on the outer wall of the middle part of the screw rod 102. During the rotation of the screw rod 102, the sponge 104 will rotate together. When the panel bonding work of the LCD substrate is completed, the clamping plate 85 is loosened, and the conveyor belt 7 drives the LCD substrate to continue to move forward. When the LCD substrate moves past the position of the sponge 104, the screw rod 102 is in a rotating state at this time, thereby driving the sponge 104 to rotate. The rotating sponge 104 contacts the panel of the LCD substrate and rolls on the panel. The bubbles that may be generated after the panel bonding are effectively discharged by this rolling and squeezing method. A second gear 105 is fixed to the side end of the housing 4, so when the screw rod 102 rotates, the second gear 105 is also driven to rotate synchronously. A second saw blade 106 is slidably provided on the outer wall of the housing 4. The second gear 105 and the second saw blade 106 are meshed with each other. Therefore, when the second gear 105 rotates, the second saw blade 106 is driven to slide along a set trajectory. The second saw blade 106 is meshed with the third gear 107, so when the second saw blade 106 slides, it drives the third gear 107 to rotate around its axis. A rotating shaft 108 is horizontally penetrated in the side wall of the housing 4, and the penetration is rotatably connected. The side end of the rotating shaft 108 is fixed with a third gear 107. The rotation of gear 107 drives shaft 108 to rotate synchronously. Fan blades 109 are fixed on the outer wall of shaft 108. The rotation of shaft 108 drives fan blades 109 to rotate rapidly, thereby accelerating the flow rate of air around the LCD display substrate. The processing device 10 can perform in-depth follow-up processing on the LCD display substrate after completing the bonding work. On the one hand, it can completely discharge the bubbles that may exist in the panel bonding process. On the other hand, it can accelerate the air flow rate around the LCD display substrate, so that the air drying speed of the glue used for bonding is significantly improved, which effectively improves the processing quality and production efficiency of the product and ensures the stability and reliability of the production process of the LCD display substrate.

[0038] A method for using a panel laminating device for producing a liquid crystal display screen, using the above-mentioned panel laminating device for producing a liquid crystal display screen, comprising the following steps:

[0039] Step 1: Place the panel coated with glue in the groove of the loading plate 81, operate the cylinder 5 to drive the suction cup 6 downward, so that the panel coated with glue is adsorbed on the suction cup 6, and then operate the cylinder 5 to raise the suction cup 6;

[0040] Step 2: Place the LCD substrate on the conveyor belt 7, pull out the loading plate 81, and make the LCD substrate follow the conveyor belt 7 to the panel bonding work area, stop and be lifted up at the same time, and control the cylinder 5 to drive the suction cup 6 downward to press the LCD substrate;

[0041] Step 3: After the pressing is completed, the air cylinder 5 is controlled to raise the suction cup 6, and the loading plate 81 is pushed back, so that the LCD screen with the panel bonded continues to move along the conveyor belt 7, and the bubbles are discharged through the sponge 104;

[0042] Step 4: Collect the LCD screen that has completed all the work from the end of the conveyor belt 7, inspect it, and pack it into the warehouse after inspection.

[0043] Working principle: After the suction cup 6 completes the loading process, the LCD display substrate is placed on the conveyor belt 7, and the transmission wheel 2 starts to rotate. The friction with the conveyor belt 7 drives it to slide, so that the LCD display substrate moves to the center position, and then the loading plate 81 is pulled out. The pulling-out action of the loading plate 81 drives the first saw blade 82 to slide, and the sliding of the first saw blade 82 causes the first gear 83 to rotate. The rotation of the first gear 83 then drives the saw plate 84 to slide. The sliding of the saw plate 84 finally drives the splint 85 to slide toward the center. After the splint 85 slides into place, it prevents the LCD display substrate from continuing to move with the conveyor belt 7, and in this process, the positioning and clamping of the LCD display substrate are achieved.

[0044] In the working process, when the clamping plate 85 starts to slide, due to the existence of the guide rod 91, its sliding path is strictly limited to avoid possible swinging, and the sliding of the clamping plate 85 will give a driving force to the guide rod 91, so that the guide rod 91 slides accordingly, and the sliding of the guide rod 91 will drive the connecting rod 92 connected thereto. At this time, the left and right groups of connecting rods 92 gradually approach each other under the action of the guide rod 91, and this approaching movement is transmitted to the hinge rod 93, driving the hinge rod 93 to rotate. As the left and right groups of hinge rods 93 continue to approach each other, the distance between them gradually shortens, and correspondingly, the angle between them becomes smaller and smaller, and the hinge point between the two groups of hinge rods 93 gradually rises during this change, thereby driving the hinge block 94 to move upward, and the upward movement of the hinge block 94 further pushes the push plate 95 to move upward. In this process, the push plate 95 is stably supported and restricted by the telescopic rod 96, and always maintains a stable horizontal state without tilting. Finally, the push plate 95 moves upward to lift up the liquid crystal display substrate placed above it.

[0045] During the sliding of the left clamping plate 85, the slider 103 will be linked to produce displacement. When the slider 103 is displaced, the screw rod 102 will be driven to rotate. During the rotation of the screw rod 102, the sponge 104 will be driven to rotate together. After the panel bonding work of the LCD display substrate is completed, the clamping plate 85 is loosened, and the conveyor belt 7 drives the LCD display substrate to continue to move forward. When the LCD display substrate passes through the sponge 104, the rotation of the screw rod 102 drives the sponge 104 to be in a rotating state. It contacts the LCD display substrate panel and rolls on the panel, thereby discharging the bubbles generated after the panel bonding. At the same time, the rotation of the screw rod 102 will also drive the second gear 105 to rotate. When the second gear 105 rotates, it will drive the second saw blade 106 to slide. The sliding of the second saw blade 106 will drive the third gear 107 to rotate. The rotation of the third gear 107 will drive the rotating shaft 108 to rotate. The rotation of the rotating shaft 108 will drive the fan blade 109 to rotate, thereby accelerating the flow rate of air around the LCD display substrate.

[0046] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
