Description

Technical Field

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

[0002] In today's digital age, liquid crystal displays are widely used in various electronic devices such as TVs, computers, mobile phones, and tablets due to their significant advantages of low power consumption, small size, and low radiation. They have become an indispensable part of people's daily life and work. In the production process of liquid crystal displays, panel lamination is a crucial step, and its lamination quality directly determines the display effect, stability, and service life of liquid crystal displays, thereby affecting the competitiveness of products in the market.

[0003] A panel laminating device for liquid crystal display production with the patent publication number CN117572679B includes a bottom plate. Four columns are fixed on the upper side of the bottom plate, and a top plate is fixed at the upper ends of the four columns. A controller is installed on one side of the top plate, and two downward pressure servo cylinders are installed on the upper side of the top plate. The telescopic ends of the two downward pressure servo cylinders are fixed with a lifting cross plate. Through the opposing pressing mechanism of the present invention, rolling can be simultaneously performed from the middle position to both ends of the touch screen, so that the air between the touch screen and the liquid crystal display can be evenly and stably discharged to both ends, as much as possible avoiding the air flow disorder generated when the air between the two is discharged due to the too fast vertical lamination speed of the touch screen and the liquid crystal display, resulting in some bubbles remaining after their lamination, which is beneficial to improving the lamination quality of liquid crystal displays.

[0004] However, the above panel laminating device for liquid crystal display production does not have a good positioning mechanism, resulting in the need for a large amount of time for workers to position the liquid crystal display after placing it on the support table. Otherwise, situations such as the panel being misaligned are likely to occur, increasing the rejection rate of products. Summary of the Invention

[0016] The present invention provides a panel laminating device for liquid crystal display production. It has the following beneficial effects:

[0017] (1) The present invention is provided with a positioning device. When the J-shaped movable rods move away from each other and the panel to be laminated is slowly placed down, through the cooperation of the triangular plate and the movable block, the positioning block drives the liquid crystal display to be placed exactly in the middle of the support platform, avoiding the need for manual positioning of the liquid crystal display by the staff after placing it on the support platform, so that the liquid crystal display is more flat when laminated with the panel, and solving the problem that the panel and the liquid crystal display are not completely aligned during lamination; the sliding of the positioning block drives the sliding of the support rod, and when the support rod slides, it cooperates with the second spring and the guiding block to move the sliding block up and down, knocking on the bottom plate and the support platform, so that the support platform drives the liquid crystal display to vibrate, solving the problem that the two ends of the liquid crystal display are prone to different heights when sliding down along the positioning block, thus making the position of the liquid crystal display and the panel more neat.

[0018] (2) The present invention is provided with a stabilizing device. While positioning the liquid crystal display, the cam is used to push the sliding rod to slide, and it cooperates with the cross bar and the third spring to drive the fixed rod to move, clamping the liquid crystal display after it completely drops onto the support platform, thereby fixing the liquid crystal display in the center of the support platform, and solving the problem that the vibration generated by the device during the panel lamination work easily causes the liquid crystal display to shift and unable to be laminated neatly.

[0019] (3) The present invention is provided with a cleaning device. When working, the sliding of the trapezoidal plate drives the sliding of the limiting rod. Cooperating with the fixed block, the limiting block and the fourth spring, the metal rod is pushed to clean above the J-shaped movable rod, sweeping away the sundries on the J-shaped movable rod. At the same time, cooperating with the fifth spring and the guiding strip, the friction sleeve slides back and forth on the metal rod to rub the metal rod to generate static electricity, which can adsorb small sundries, thereby removing the small fluff-like sundries that may exist on the J-shaped movable rod, solving the problem that there are sundries between the panel and the liquid crystal display screen during lamination, resulting in bubbles.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 6 An embodiment of the present invention is as follows: A panel laminating device for liquid crystal display production includes a bottom plate 1. Support columns are fixed on the upper and lower surfaces of the bottom plate 1. One end of the support column above the bottom plate 1 away from the bottom plate 1 is fixed with a top plate 2. A piston rod passes through the top plate 2 and is slidably connected at the passing position. The piston rod is driven by a cylinder. The bottom end of the piston rod is fixed with a laminating device main body 3. A support table 4 is fixed on the upper surface of the bottom plate 1. A motor 5 is fixed on the upper surface of the bottom plate 1. The output end of the motor 5 is fixed with a gear. The gear meshes with a J-shaped movable rod 6. A positioning device for conveniently adjusting the position of the display screen is arranged on the bottom surface of the support table 4.

[0029] The positioning device includes a triangular plate 71, a movable block 72, a positioning block 73, a support rod 74, a first spring 75, a second spring 76, a sliding block 77 and a guide block 78. The triangular plate 71 is fixedly connected to the side wall of the J-shaped movable rod 6. The liquid crystal display screen is placed above the positioning block 73. When the motor 5 is started, the motor 5 drives the gear to rotate. When the gear rotates, it drives the J-shaped movable rods 6 to move away from each other. When the J-shaped movable rods 6 move away from each other, the triangular plate 71 on its side wall also slides along with the J-shaped movable rod 6. The bottom surface of the triangular plate 71 is slidably connected to the upper surface of the support table 4. The movable block 72 is slidably connected to the upper surface of the support table 4. The rounded surface of the movable block 72 is slidably connected to the inclined surface of the triangular plate 71. When the triangular plate 71 slides, it pushes the movable block 72 to slide in a direction away from the J-shaped movable rod 6. The positioning block 73 is fixedly connected to the side wall of the movable block 72. The inner wall of the positioning block 73 fits against the side wall of the support table 4. When the triangular plate 71 slides, it drives the positioning block 73 to slide together. The two groups of positioning blocks 73 move away from each other, and the liquid crystal display screen slides downward along the inclined surface of the positioning block 73 and gradually falls onto the support table 4, so that the liquid crystal display screen is at the center of the support table 4. The support rod 74 is fixedly connected to the bottom surface of the positioning block 73. When the positioning block 73 slides, it drives the support rod 74 to slide. The support rod 74 is slidably connected to the upper surface of the bottom plate 1. The first spring 75 is fixedly connected to the back of the support rod 74. One end of the first spring 75 away from the support rod 74 is fixedly connected to the inner wall of the support table 4. When the support rod 74 slides, it stretches the first spring 75. A convex block is fixed on the side wall of the support rod 74. When the support rod 74 slides, it drives the convex block to move together. The second spring 76 is fixedly connected to the bottom surface of the convex block. The movement of the convex block drives the second spring 76 to move together. The sliding block 77 is fixedly connected to one end of the second spring 76 away from the convex block. The second spring 76 drives the sliding block 77 to slide. The guide block 78 is fixedly connected to the upper surface of the support table 4. When the sliding block 77 slides to the guide block 78, it slides upward along the guide block 78 and compresses the second spring 76 at the same time. When it leaves the guide block 78, it moves downward under the thrust of the second spring 76 and knocks on the bottom plate 1 and the support table 4, causing the support table 4 to vibrate. When the J-shaped movable rods 6 move away from each other and the panel to be fitted is slowly put down, the positioning device drives the positioning block 73 through the cooperation of the triangular plate 71 and the movable block 72 to place the liquid crystal display screen exactly in the middle of the support table 4, avoiding the need for the staff to manually position the liquid crystal display screen after placing it on the support table 4. Thus, the liquid crystal display screen is flatter when being fitted with the panel, solving the problem that the panel and the liquid crystal display screen are not completely aligned easily when being fitted;The sliding of the positioning block 73 drives the sliding of the support rod 74. When the support rod 74 slides, it cooperates with the second spring 76 and the guide block 78 to move the sliding block 77 up and down, knocking on the bottom plate 1 and the support table 4, so as to drive the liquid crystal display screen to shake through the support table 4, solving the problem that the two ends of the liquid crystal display screen are prone to different heights when sliding down along the positioning block 73, and thus making the position of the liquid crystal display screen and the panel more neat.

[0030] When this embodiment works: Place the liquid crystal display screen above the positioning block 73, start the motor 5, the motor 5 drives the gear to rotate, when the gear rotates, it drives the J-shaped movable rods 6 to move away from each other. When the J-shaped movable rods 6 move away from each other, the triangular plates 71 on their side walls also slide along with the J-shaped movable rods 6. When the triangular plates 71 slide, they push the movable block 72 to slide in a direction away from the J-shaped movable rods 6. When the triangular plates 71 slide, they drive the positioning block 73 to slide together. When the positioning block 73 slides, it drives the support rod 74 to slide, and at the same time stretches the first spring 75. The two positioning blocks 73 move away from each other, and the liquid crystal display screen slides down along the inclined surface of the positioning block 73 and gradually falls onto the support table 4, making the liquid crystal display screen located at the center of the support table 4. When the support rod 74 slides, it drives the convex block to move together. The movement of the convex block drives the second spring 76 to move together. The second spring 76 drives the sliding block 77 to slide. When the sliding block 77 slides to the guide block 78, it slides upward along the guide block 78, and at the same time compresses the second spring 76. When leaving the guide block 78, it moves downward under the thrust of the second spring 76, knocking on the bottom plate 1 and the support table 4, making the support table 4 vibrate, so that the two sides of the liquid crystal display screen are at the same height when sliding on the inclined surface of the positioning block 73, and at the same time driving the liquid crystal display screen to vibrate, shaking out the bubbles in the adhesive applied on the liquid crystal display screen.

[0031] Please refer to Figures 1 - 6, on the basis of the above embodiments, in another embodiment of the present invention, stabilizing devices for facilitating the fixation of the display screen are provided on both sides of the positioning device. The stabilizing device includes a cam 81, a sliding rod 82, a cross bar 83, a third spring 84, and a fixing rod 85. The cam 81 is fixedly connected to the upper surface of the gear. When the gear rotates, the cam 81 rotates together. The sliding rod 82 is slidably connected to the bottom surface of the support platform 4. When the cam 81 rotates, it pushes the sliding rod 82 to slide. The cross bar 83 is fixedly connected to the upper end of the sliding rod 82. When the sliding rod 82 slides, it drives the cross bar 83 to slide. The cross bar 83 is slidably connected to the upper surface of the support platform 4. The third spring 84 is fixedly connected to the side wall of the cross bar 83. The fixing rod 85 is fixedly connected to the end of the third spring 84 away from the cross bar 83. The cross bar 83 drives the third spring 84 and the fixing rod 85 to move, so that the liquid crystal display screen falls onto the support platform 4 along the inclined surface of the fixing rod 85. When the cam 81 rotates away from the sliding rod 82, the sliding rod 82 slides towards the center, driving the cross bar 83 to slide towards the center. The sliding of the cross bar 83 drives the third spring 84 and the fixing rod 85 to move. The fixing rod 85 pushes the liquid crystal display screen towards the center of the support platform 4. At the same time, the cross bar 83 continues to slide, compressing the third spring 84. The elastic force of the third spring 84 pushes the fixing rod 85 to clamp the liquid crystal display screen. While positioning the liquid crystal display screen, the stabilizing device pushes the sliding rod 82 to slide through the cam 81, and cooperates with the cross bar 83 and the third spring 84 to drive the fixing rod 85 to move, clamping the liquid crystal display screen after it completely falls onto the support platform 4, thereby fixing the liquid crystal display screen at the center of the support platform 4, and solving the problem that the vibration generated by the device during the panel bonding work easily causes the liquid crystal display screen to be displaced and unable to be bonded neatly.

[0032] A cleaning device for facilitating the cleaning of fine dust is provided on the side wall of the support table 4. The cleaning device includes a trapezoidal plate 91, a limiting rod 92, a fixing block 93, a metal rod 94, a limiting block 95, a fourth spring 96, a friction sleeve 97, a fifth spring 98 and a guiding strip 99. The trapezoidal plate 91 is fixedly connected to the side wall of the positioning block 73. When the positioning block 73 slides in the direction away from the J-shaped movable rod 6, it drives the trapezoidal plate 91 to move as well. The limiting rod 92 is slidably connected to the side wall of the support table 4. When the trapezoidal plate 91 moves, it pushes the limiting rod 92 to slide. The inclined surface of the trapezoidal plate 91 is slidably connected to the limiting rod 92. The fixing block 93 is slidably connected to the inner wall of the limiting rod 92. When the limiting rod 92 slides, it drives the fixing block 93 to move together. The metal rod 94 is fixedly connected to the side wall of the fixing block 93. The fixing block 93 drives the metal rod 94 to move, scraping away the fine debris above the J-shaped movable rod 6. The limiting block 95 is fixedly connected to one end of the metal rod 94 away from the fixing block 93. The fourth spring 96 is fixedly connected to the bottom surface of the limiting block 95. One end of the fourth spring 96 away from the limiting block 95 is fixed with a short rod, and the short rod is slidably connected to the bottom surface of the support table 4. The metal rod 94 passes through the friction sleeve 97, and the passing-through part is slidably connected. The fifth spring 98 is fixedly connected to the side wall of the friction sleeve 97. One end of the fifth spring 98 away from the friction sleeve 97 is fixedly connected to the side wall of the fixing block 93. When the metal rod 94 moves, it drives the friction sleeve 97 and the fifth spring 98 to move together. The guiding strip 99 is fixedly connected to the upper surface of the support table 4. When the friction sleeve 97 moves to the guiding strip 99, the friction sleeve 97 slides along the guiding strip 99, rubbing against the metal rod 94. When the metal rod 94 is rubbed, static electricity is generated, sucking up the fine debris that may not be scraped away on the J-shaped movable rod 6, reducing the fine debris remaining on the J-shaped movable rod 6. When the cleaning device is working, the sliding of the trapezoidal plate 91 drives the limiting rod 92 to slide, and in cooperation with the fixing block 93, the limiting block 95 and the fourth spring 96, it pushes the metal rod 94 to clean above the J-shaped movable rod 6, sweeping away the debris on the J-shaped movable rod 6. At the same time, in cooperation with the fifth spring 98 and the guiding strip 99, the friction sleeve 97 slides back and forth on the metal rod 94, rubbing against the metal rod 94 to generate static electricity, which can adsorb the fine debris, thereby removing the fine fluff-like debris that may exist on the J-shaped movable rod 6, solving the problem of the presence of debris between the panel and the liquid crystal display during bonding, resulting in bubbles.

[0033] During the operation of this embodiment: When the gear rotates, it drives the cam 81 to rotate together. When the cam 81 rotates, it pushes the sliding rod 82 to slide. When the sliding rod 82 slides, it drives the cross bar 83 to slide. The cross bar 83 drives the third spring 84 and the fixed rod 85 to move, causing the liquid crystal display screen to fall onto the support table 4 along the inclined surface of the fixed rod 85. When the cam 81 rotates away from the sliding rod 82, the sliding rod 82 slides towards the center, driving the cross bar 83 to slide towards the center. The sliding of the cross bar 83 drives the third spring 84 and the fixed rod 85 to move. The fixed rod 85 pushes the liquid crystal display screen towards the center of the support table 4. At the same time, the cross bar 83 continues to slide, compressing the third spring 84. The elastic force of the third spring 84 pushes the fixed rod 85 to clamp the liquid crystal display screen.

[0034] When the positioning block 73 slides in the direction away from the J-shaped movable rod 6, it drives the trapezoidal plate 91 to move as well. When the trapezoidal plate 91 moves, it pushes the limiting rod 92 to slide. When the limiting rod 92 slides, it drives the fixed block 93 to move together. The fixed block 93 drives the metal rod 94 to move, scraping away the fine debris above the J-shaped movable rod 6. When the metal rod 94 moves, it drives the friction sleeve 97 and the fifth spring 98 to move together. When the friction sleeve 97 moves to the guide bar 99, the friction sleeve 97 slides along the guide bar 99, rubbing against the metal rod 94. When the metal rod 94 is rubbed, static electricity is generated, sucking up the fine debris that may not be scraped away on the J-shaped movable rod 6, reducing the fine debris remaining on the J-shaped movable rod 6.
