Placement blocks 303 are placed in the placement grooves 302, and the top of the placement blocks 303 is provided with a groove in the same shape as the liquid crystal display screen, which is used to stably place the liquid crystal display screen and quickly replace and adjust to liquid crystal display screens of different specifications. A heating sheet 304 is provided in the middle of the inner side of the placement plate 301 to quickly adjust the temperature of the placement block 303 so that the position of the liquid crystal display screen maintains a suitable bonding temperature; A transparent plate 305 is provided through the side wall where the placement plate 301 contacts the side wall of the sealed box 1 , so as to facilitate operators to observe the situation inside the sealed box 1 .

[0035] The laminating mechanism 4 specifically includes a screw rod 401, a motor 402, a mounting frame 403, a limiting shell 404, an extrusion frame 405, a first electric push rod 406, a connecting column 407 and an extrusion plate 408; Among them, screw rods 401 are symmetrically rotated on the two inner side walls of the sealing box 1 about the placement plate 301, and a motor 402 is provided on the inner side of the sealing box 1. The output shaft of the motor 402 is connected to the screw rod 401 through a coupling. A mounting frame 403 is threadedly provided between the two screw rods 401. A plurality of limiting shells 404 are provided in the middle of the mounting frame 403. The limiting shells 404 correspond to the placement blocks 303 on the placement plate 301 one by one. The limiting shells 404 are all located directly above the corresponding placement blocks 303, and are used to drive the extrusion plate 408 to move to the extrusion position and limit the extrusion position; Among them, an extrusion frame 405 is placed on the top plate of the mounting frame 403, a first electric push rod 406 is provided on the top of the mounting frame 403, the telescopic rod of the first electric push rod 406 is connected to the extrusion frame 405, a plurality of connecting columns 407 are provided at the bottom of the extrusion frame 405, the connecting columns 407 correspond to the limiting shells 404 one by one, and an extrusion plate 408 is provided at the bottom of the connecting columns 407, and the extrusion plates 408 all penetrate the adjacent limiting shells 404 to complete the extrusion and bonding operation of the liquid crystal display screen, and the short-distance moving extrusion is conducive to ensuring the moving distance of the extrusion plate 408 to avoid excessive extrusion and damage to the liquid crystal display screen.

[0036] Exemplarily, when in use, the operator starts the temperature control component 2 to keep a certain temperature in the sealed box 1, and at the same time, pulls out the placement plate 301 from the sealed box 1 and places the placement block 303 in the placement groove 302, and then sequentially stacks the LCD screen, optical glue and glass cover plate into the groove on the top of the placement block 303. After placement, the operator pushes the placement plate 301 into the sealed box 1 and heats the placement plate 301 and the placement block 303 through the heating sheet 304, and then starts the motor 402 to drive the screw rod 401. The first electric push rod 406 is then started. In the initial state, the first electric push rod 406 is in an extended state. After the first electric push rod 406 is started, the first electric push rod 406 contracts, driving the extrusion frame 405 to move downward. The extrusion plate 408 connected to the extrusion frame 405 through the connecting column 407 is driven to move downward relative to the limiting shell 404, and the LCD screen, The optical glue and the glass cover plate are heat-pressed and bonded. After the bonding is completed, the operator controls the motor 402 to rotate in the opposite direction, lifts the mounting frame 403 upward, and makes the extrusion plate 408 and the limiting shell 404 away from the placement plate 301, so that the operator can pull the placement plate 301 out of the sealing box 1 to replace the LCD screen that needs to be bonded. At the same time, when black-and-white LCD screens of different specifications need to be heat-pressed and bonded, the operator can replace the placement block 303 with the corresponding groove to place black-and-white LCD screens of different specifications at the same time for heat-pressing and bonding. In this way, by placing multiple LCD screens on the placement plate 301 at one time, and then using the mounting frame 403 to drive the same number of limiting shells 404 and the extrusion plate 408 to heat-press and bond all the LCD screens, the efficiency of hot-pressing and bonding batches of black-and-white LCD screens is improved, and in the face of black-and-white LCD screens of different specifications, the device only needs to replace the corresponding placement block 303 to perform the bonding operation, thereby improving the adaptability of the device, and the device has a simple structure and is easy to operate, which greatly reduces the operating cost.

[0037] Example 2 like Figures 8 to 11As shown, on the basis of Example 1, it also includes a cover plate pushing mechanism 5, which specifically includes a placement box 501, a protective cover 502, a second electric push rod 503, a limit frame 504, a push plate 506, an elastic member 509 and a limit ball 510. A placement box 501 is provided at the top of the inner side of the sealed box 1 near each limit shell 404, a protective cover 502 is provided at the top of the placement box 501, a second electric push rod 503 is provided at the bottom of the placement box 501, and the second electric push rod 503 is connected to an external controller. A limit frame 504 is provided at the lower part of the outer side of the placement box 501, and the limit frame 504 and the second electric push rod The placing box 501 is connected with a telescopic rod 503, a limiting groove 505 is provided on the inner wall of the limiting frame 504, a push plate 506 with a thickness less than that of the glass cover is provided at the bottom of the placing box 501, an opening is provided on one side of the limiting shell 404 facing the rear side wall of the sealing box 1, a discharge port 507 is provided on the lower part of the side of the placing box 501 close to the opening of the limiting shell 404, the opening of the limiting shell 404 is connected with the discharge port 507, two sliding grooves 508 are provided on the two side walls symmetrical about the opening inside the limiting shell 404, and elastic parts 509 are provided in the sliding grooves 508, and limiting balls 510 are slidably provided in the sliding grooves 508, and the limiting balls 510 are connected with the elastic parts 509.

[0038] Before the device is started, the operator opens the protective cover 502 and stacks a certain number of glass cover plates into each placement box 501. Then, after the device is started, the operator only needs to put the LCD screen and optical glue on the placement block 303. In the initial state, the screw rod 401 controls the mounting frame 403 to remain in the uppermost position, and the second electric push rod 503 remains in a retracted state, and the push plate 506 is located at a position away from the discharge port 507 of the placement box 501. Before the mounting frame 403 descends, the external controller extends and retracts the second electric push rod 503. The second electric push rod 503 drives the limit frame 504 to move downward to the lowest position and then returns to the initial state. The push plate 506 first moves to a square close to the discharge port 507 under the action of the limit groove 505. In this process, a cover plate is pushed from the placement box 501 to the limit shell 404. After the push plate 506 moves to the discharge port 507 position, the limit frame 504 moves upward. Under the action, the push plate 506 moves away from the discharge port 507 and returns to the initial position, the glass cover plate in the placement box 501 falls a distance of one block, and the glass cover plate that falls just above the four limiting balls 510 moves downward with the limiting shell 404 to the position just above the placement block 303, and when the extrusion plate 408 moves downward, the glass cover plate squeezes the four limiting balls 510 into the slide groove 508 under the extrusion action of the extrusion plate 408, the elastic member 509 is compressed, and the glass cover plate falls to the top of the optical glue of the liquid crystal display screen, and then the hot pressing bonding is completed under the action of the extrusion plate 408. After completion, the mounting frame 403 drives the limiting shell 404 to return to the initial position upward, and the above operation is repeated. In this way, when performing the bonding operation, the operator only needs to place the liquid crystal display screen into the groove at the top of the placement block 303 and then inject the optical glue, without having to place the glass cover plate according to its position, and the operation is simple, which reduces the workload of the operator and improves work efficiency.

[0039] like Figure 12 to Figure 14As shown, on the basis of Example 1, it also includes a dispensing mechanism 6, which specifically includes a fixed frame 601, a slider 602, an electric control nozzle 603, a glue feeding pipe 604, a fixed column 605, a connecting belt 606, a movable frame 607 and a limiting frame 608. A fixed frame 601 is provided at a position between the mounting frame 403 and the placement plate 301 on the inner side of the sealing box 1. A plurality of square grooves 6011 are symmetrically opened at the bottom of the fixed frame 601. The square grooves 6011 correspond to the placement blocks 303 on the placement plate 301 one by one. Sliders 602 are slidably provided in the square grooves 6011. An electric-controlled nozzle 603 is provided at the bottom of the slider 602, and the electric-controlled nozzle 603 is connected to an external controller. A rubber hose is provided at the middle position of the bottom of the fixed frame 601. Fixed columns 605 are provided on both sides of the slider 602 symmetrically with the slide groove 508 as the center. The bottom of the fixed frame 601 is connected to the movable frame 607 through a connecting belt 606. A limiting frame 608 is placed on the top of the fixed frame 601, which is located directly above each square groove 6011. The limiting frame 608 is limited by the fixed column 605 of the slider 602 in the corresponding square groove 6011, and the limiting frame 608 is fixedly connected to the movable frame 607.

[0040] In the initial state, the mounting frame 403 is located at the upper position of the inner side of the sealing box 1 under the action of the screw rod 401, and the movable frame 607 and the limiting frame 608 are pulled up and away from the fixed frame 601 under the action of the connecting belt 606, and the slider 602 in the square groove 6011 is kept at the position farthest from the center of the fixed frame 601 in the square groove 6011 under the action of the limiting frame 608, and the electric control nozzle 603 is kept at the position closest to the placement block 303. When the device is in use, the operator can place the LCD screen on the placement block 303. Before the mounting frame 403 descends, the external controller controls the electric control nozzle 603 to spray a certain amount of optical glue onto the LCD screen on the placement block 303 near the position, and then the mounting frame 403 moves downward under the action of the screw rod 401, and the movable frame 607 and the limiting frame 608 move downward together, and the limiting frame 608 drives downward through the fixed column 605 The slider 602 moves in the square groove 6011 toward the center of the fixed frame 601, and the electric-controlled nozzle 603 moves away from the placement block 303. The mounting frame 403 continues to move downward, the connecting belt 606 is bent and folded, and then the LCD screen is bonded. After the bonding is completed, the mounting frame 403 is driven upward by the screw rod 401, and the connecting belt 606 is first stretched and straightened, and then the mounting frame 403 continues to drive the moving frame 607 and the limiting frame 608 upward back to the initial position, and the electric-controlled nozzle 603 is driven by the slider 602 back to the initial position close to the placement block 303. In this way, when performing the bonding operation, the operator only needs to pull the placement plate 301 out of the sealing box 1 and then place the LCD screen on the placement block 303, and finally push the placement plate 301 into the sealing box 1. Other steps can be controlled by an external controller to complete the bonding of the LCD screen and improve operating efficiency.

[0041] like Figure 15 to Figure 16 As shown, on the basis of Example 1, a sealing plate 7, a vacuum pump 8 and a sealing strip 9 are specifically included. A sealing plate 7 is provided at the rear side of each placement groove 302 on the placement plate 301. The sealing plate 7 is in contact with the limiting shell 404. A vacuum pump 8 penetrating the sealing plate 7 is provided on the rear side of the sealing plate 7, and a sealing strip 9 is provided on the front side of the sealing plate 7.

[0042] After the mounting frame 403 drives the limiting shell 404 to move downward to cover the placement block 303, the sealing plate 7 and the limiting shell 404 are in contact and fit to cover the side of the limiting shell 404. Finally, the limiting shell 404 is completely sealed under the action of the sealing plate 7 and the placement plate 301. The sealing strip 9 ensures the sealing. When extrusion is performed for extrusion fitting, the externally controlled vacuum pump 8 is started to maintain a certain vacuum degree in the limiting shell 404 to ensure the fitting effect.

[0043] like Fig.13As shown, on the basis of embodiment 1, a counterweight block 10 is further included, and a configuration block is provided in the middle of the movable frame 607 by bolt connection.

[0044] The counterweight 10 on the movable frame 607 can prevent the movable frame 607 from being stuck at a certain position on the top of the fixed frame 601 and unable to move downward due to friction, thereby ensuring the continuity and integrity of the extension and retraction action of the electric-controlled nozzle 603.
