Description

Technical Field

[0001] The present invention relates to the field of liquid crystal display production, and specifically to a panel laminating device for liquid crystal display production. Background Technique

[0002] A liquid crystal display is a type of flat panel display used for the screen display of televisions and computers. The advantages of this display are low power consumption, small size, and low radiation. The liquid crystal display uses a liquid crystal solution between two pieces of polarizing material, and when an electric current passes through the liquid, the liquid crystal rearranges to achieve the purpose of imaging.

[0003] During the production process of liquid crystal displays, it is necessary to laminate the display screen, touch screen, and glass plate. The existing lamination techniques include frame lamination, full lamination, and zero lamination. Frame lamination is simply using double-sided tape to fix the touch screen on the four sides of the display screen. The process is simple and the cost is low. However, due to the air layer between the display screen and the touch screen, the display effect is greatly reduced after light refraction, which becomes the biggest defect of frame lamination. The full lamination technique is a lamination industry that uses water glue or optical glue to completely and seamlessly bond the liquid crystal screen and the touch screen panel together. Usually, OCA glue and LOCA water glue are used. The zero lamination technique is between full lamination and frame lamination. It mainly fills a non-gummy transparent medium with a refractive index equivalent to that of glass between the touch panel and the liquid crystal screen. In the use of the full lamination technique, first, the operator places the liquid crystal screen inside a set fixture, then tears off the protective film on one side of the touch panel, and then laminates the side of the touch panel without the film with the liquid crystal screen in the fixture. Through the fixed groove of the fixture, the touch panel is aligned with the liquid crystal screen. Then, the fixture is moved into the lamination device through a transmission device, and through the lamination device, the liquid crystal screen and the touch screen are laminated. After lamination, the liquid crystal screen and the touch screen are sent into the defoaming chamber for defoaming.

[0004] In the prior art, for the full lamination technique in the liquid crystal screen and touch screen technology, during the processing, the operator needs to place the liquid crystal screen in the fixture, then manually tear off the protective film of the touch screen, and then laminate the film-covered side of the touch screen with the liquid crystal screen. Then, the laminated display screen is placed inside the lamination device to complete the lamination technique of the display screen. In the full lamination technique, the step of manually tearing off the touch screen reduces the work efficiency. Summary of the Invention

[0025] 1. The present invention is provided with a first loading mechanism and a second loading mechanism. The display screen is placed in the groove of the first loading bin. At this time, the display screen contacts the inclined surface of the sliding block. Then, gently press the display screen downward.

Through the fixed connection between the rotating disk and the second transmission mechanism, the two groups of second transmission mechanisms perform circular motion centered on the rotating disk, so that the third gear at the end of one group of second transmission mechanisms makes circular motion centered on the rotating disk. And through the meshing of the third gear with the tooth ring at the bottom of the fixed cylinder, the third gear drives a group of second threaded sleeve rods to rotate self. Through the threaded connection between the second threaded sleeve rod and the second threaded rod, the second threaded rod drives the second sealing plug to horizontally move on the inner wall of the second adsorption mechanism, so that the spring telescopic tube and the third suction cup generate an adsorption force, and the protective film falls off from the touch screen, thus completing the step of automatic film removal, reducing the manual operation steps and improving the production efficiency.

Through the fixed connection between the rotating disk 602 and the second transmission mechanism 604, it is ensured that the second transmission mechanism 604 makes a circular motion with the rotating disk 602 as the center. And the rotating disk 602 extends to the other side of the fixed frame 2. The second adsorption mechanism 605 is arranged at the end of the second transmission mechanism 604. By the rotation of the second transmission mechanism 604, it is ensured that the air pressure inside the second adsorption mechanism 605 is changed, thereby ensuring the adsorption of the protective film on the surface of the touch screen.

[0048] Please refer to Figure 8 、 Figure 9 and Figure 10, the second transmission mechanism 604 includes a second threaded sleeve rod 6041, a second threaded rod 6042, a second sealing plug 6043, two groups of second gears 6044 and a third gear 6045. The second threaded sleeve rod 6041 is arranged inside the rotating disk 602, and the second threaded sleeve rod 6041 is fixedly connected to the rotating disk 602. The second threaded rod 6042 is arranged inside the second threaded sleeve rod 6041, and the second threaded rod 6042 is threadedly connected to the second threaded sleeve rod 6041. The second sealing plug 6043 is arranged at the end of the second threaded rod 6042. By the rotation of the second threaded sleeve rod 6041 and the threaded connection between the second threaded sleeve rod 6041 and the second threaded rod 6042, it is ensured that the second threaded rod 6042 drives the second sealing plug 6043 to move horizontally on the inner wall of the second adsorption mechanism 605, thereby ensuring that the air pressure inside the second adsorption mechanism 605 is changed, and thus ensuring the adsorption of the touch screen protection film. The second gears 6044 are arranged outside the second threaded sleeve rod 6041, and the two groups of second gears 6044 are meshed with each other. By the meshed connection of the two groups of second gears 6044, it is ensured that the two groups of second threaded sleeve rods 6041 rotate in opposite directions, ensuring that the moving directions of the two groups of second sealing plugs 6043 are opposite. And the third gear 6045 is arranged at the end of one group of second threaded sleeve rods 6041. When the second threaded sleeve rod 6041 makes a circular motion along with the rotating disk 602, the third gear 6045 makes a circular motion centered on the rotating disk 602, and through the meshing of the third gear 6045 with the internal tooth ring of the fixed cylinder 601, it is ensured that the third gear 6045 drives the second threaded sleeve rod 6041 to rotate self.

[0049] Please refer to Figure 8 and Figure 9 , the second adsorption mechanism 605 includes a sealing tube 6051, a sealing plate 6052, a spring telescopic tube 6053 and a third suction cup 6054. The sealing tube 6051 is arranged outside the second sealing plug 6043. By the horizontal movement of the second sealing plug 6043 inside the sealing tube 6051, it is ensured that the air pressure inside the sealing tube 6051 changes. The sealing plate 6052 is arranged in the middle of the sealing tube 6051. By arranging the sealing plate 6052 in the middle of the sealing tube 6051, it is ensured that the internal space of the sealing tube 6051 is divided into two closed bins. And the spring telescopic tube 6053 is arranged outside the sealing tube 6051, and the third suction cup 6054 is arranged at the end of the spring telescopic tube 6053. By the arrangement of the spring telescopic tube 6053 and the third suction cup 6054, and the spring telescopic tube 6053 and the third suction cup 6054 are connected to the sealing tube 6051, it is ensured that when the air pressure inside the sealing tube 6051 changes, the third suction cup 6054 sucks the protection film outside the touch screen.

[0050] Please refer to Figure 8Figure 9 and Figure 10 Inside the fixed cylinder 601, a gear ring is provided, and the gear ring provided inside the fixed cylinder 601 is in meshing connection with the third gear 6045. Through the meshing connection between the gear ring provided inside the fixed cylinder 601 and the third gear 6045, it is ensured that when the second threaded sleeve rod 6041 makes a circular motion centered on the rotating disk 602, it is ensured that the third gear 6045 drives the second threaded sleeve rod 6041 to rotate. The second sealing plug 6043 is in close fit with the inner wall of the sealing pipe 6051 and is in a sealed state. Through the close fit between the second sealing plug 6043 and the inner wall of the sealing pipe 6051 and being in a sealed state, it is ensured that when the second sealing plug 6043 moves horizontally, the air pressure inside the sealing pipe 6051 is changed.

[0051] The working principle of the present invention is as follows: When it is necessary to bond the display screen, first place the touch screen above the second loading bin 501. At this time, the touch screen contacts the second suction cup 503, and then gently press it downward to make the back surface of the touch screen fit with the second suction cup 503, so that the touch screen is adsorbed by the second suction cup 503. After the touch screen is placed, place the display screen in the groove of the first loading bin 401. At this time, the display screen contacts the inclined surface of the sliding block 403, and then gently press the display screen downward. At this time, the display screen makes the sliding block 403 squeeze the spring telescopic rod 402 to both sides through the inclined surface of the sliding block 403, so that the side surface of the display screen contacts the arc surface at the bottom of the sliding block 403, and the sliding block 403 clamps both sides of the display screen, thereby realizing the preliminary fixation of the display screen; when the display screen is pressed downward, the display screen fits with the first suction cup 3037, so that the display screen is adsorbed by the first suction cup 3037.

[0052] Further, after the display screen is placed, by starting the motor 301, the first rotating shaft 302 drives the first material storage bin 401 to rotate around the motor 301. Through the clamping groove connection between the air pipe 3036 and the first material storage bin 401, the air pipe 3036 drives the sliding shaft 3031 to perform a circular motion around the first rotating shaft 302. At this time, through the circular motion of the sliding shaft 3031 and the fixed connection between the sliding shaft 3031 and the first gear 3038, the first gear 3038 performs a circular motion around the first rotating shaft 302. At this time, through the meshing connection between the first gear 3038 and the toothed ring on one side of the fixed frame 2, the first gear 3038 drives the sliding shaft 3031 to rotate, so that the first threaded rod 3033 rotates. Through the threaded connection between the first threaded rod 3033 and the first threaded sleeve rod 3035, the first threaded rod 3033 moves in the direction of the sliding shaft 3031. At this time, the spring connecting rod 3032 contracts, driving the first sealing plug 3034 to move outward from the first threaded sleeve rod 3035. At this time, the air pressure inside the first threaded sleeve rod 3035 decreases, strengthening the adsorption force of the first suction cup 3037 on the display screen. When the first rotating shaft 302 drives the first material storage bin 401 to rotate 180°, the first sealing plug 3034 moves to the end of the first threaded sleeve rod 3035. At this time, the first suction cup 3037 reaches the maximum suction force on the display screen;

[0053] Further, when the first rotating shaft 302 rotates, the second cylinder 508 is started simultaneously, so that the second cylinder 508 pulls the second material storage bin 501 to move horizontally in the chute of the base 1, so that the first group of second material storage bins 501 is located directly below the first material loading mechanism 4;

[0054] Further, when the first rotating shaft 302 rotates, through the transmission connection between the first rotating shaft 302, the transmission belt 603 and the rotating disk 602, the rotating disk 602 rotates. Through the fixed connection between the rotating disk 602 and the second transmission mechanism 604, the two groups of second transmission mechanisms 604 perform circular motion centered on the rotating disk 602, so that the third gear 6045 at the end of one group of second transmission mechanisms 604 performs circular motion centered on the rotating disk 602. And through the engagement between the third gear 6045 and the tooth ring at the bottom of the fixed cylinder 601, the third gear 6045 drives one group of second threaded sleeve rods 6041 to rotate. Through the threaded connection between the second threaded sleeve rod 6041 and the second threaded rod 6042, the second threaded rod 6042 drives the second sealing plug 6043 to move horizontally on the inner wall of the second adsorption mechanism 605, so that an adsorption force is generated between the spring telescopic tube 6053 and the third suction cup 6054. When the spring telescopic tube 6053 faces downward, at this time, one group of second sealing plugs 6043 is at the topmost position. When the second threaded sleeve rod 6041 rotates, one group of second sealing plugs 6043 moves in the direction of the second threaded sleeve rod 6041, so that the air pressure on the inner wall of the second adsorption mechanism 605 decreases, so that the upward third suction cup 6054 generates an adsorption force. When the third suction cup 6054 rotates 180°, the adsorption force of the third suction cup 6054 reaches the minimum value. At the same time, when one group of second threaded sleeve rods 6041 rotates, through the engagement of the two groups of second gears 6044, the other group of second threaded sleeve rods 6041 rotates in the reverse direction, so that the adsorption force of the downward group of third suction cups 6054 gradually increases. When the third suction cup 6054 contacts the film surface of the touch screen, the adsorption force of the third suction cup 6054 reaches the maximum, so that the protective film of the touch screen is adsorbed, so that the protective film falls off from the touch screen. When the protective film completely falls off, at this time, the second cylinder 508 makes the second material loading bin 501 directly below the first material loading bin 401;

[0055] Furthermore, the first cylinder 505 is started to move the limit block 506 upward, so that the limit block 506 is engaged with the limit groove at the bottom of the carrying plate 502, and the limit block 506 continues to move upward, so that the touch screen carried by the carrying plate 502 is fitted with the display screen carried downward by the first loading bin 401, and at this time, the connecting column 507 is connected with the sliding groove between the two groups of second loading bins 501, ensuring that the second loading bin 501 supported by the limit block 506 moves upward, and the other group of second loading bins 501 maintains a horizontal position, and then full-pasting and gluing operations are performed (this is the prior art). While waiting for the fitting, the operator places the second group of touch screens on the inner side of the second group of second loading bins 501 (operate as above), so that the second group of touch screens is adsorbed by the second suction cup 503, and then the operator places the second group of display screens on the second loading bin 501 facing upward at this moment. Inside a loading bin 401 (operated as above), the second group of display screens are clamped by the sliding block 403, and the second group of display screens are adsorbed by the first suction cup 3037. When the first group of display screens are bonded, the motor 301 is reversed 180°. At this time, the first gear 3038 drives the sliding shaft 3031 and the first threaded rod 3033 to reverse. Through the threaded connection between the first threaded rod 3033 and the first threaded sleeve 3035, the first sealing plug 3034 moves in the opposite direction, thereby increasing the air pressure inside the first threaded sleeve 3035, so that the first suction cup 3037 gradually loses its adsorption force on the display screen until the first loading bin 401 is reversed 180° and the first suction cup 3037 completely loses its adsorption force on the display screen. Then, the bonded LCD screen is taken out from the first loading bin 401, thereby completing the full bonding technology for the LCD screen.
