Specific implementation manner

[0022] The following further describes the present utility model in conjunction with the embodiments shown in the accompanying drawings.

[0023] A device for laminating the surface of a liquid crystal display, as Figures 1-5 shown, includes a base 1 and a drive motor 2. The drive motor 2 is installed on the right side of the base 1. The front and rear sides of the base 1 are open. It is characterized in that it further includes a threaded rod 3, a guide block 4, a guide rail 5, a slider 6, a telescopic rod 10, a fixing plate 7 and a roller 81. The left and right sides between the inner walls of the base 1 are rotatably connected with a threaded rod 3. The right side of the threaded rod 3 is fixedly connected to the output shaft of the drive motor 2. A guide block 4 is threadedly connected to the threaded rod 3. Connecting rods 41 are fixedly connected to both the front and rear sides of the guide block 4. Two sliders 6 are fixedly connected to the ends of the connecting rods 41 far away from the guide block 4. The sliders 6 on the connecting rods 41 are symmetrically arranged. Guide rails 5 are fixedly connected to both the front and rear sides of the base 1. The sliders 6 are all slidably connected to the guide rails 5. Two groups of telescopic rods 10 are fixedly connected to the tops of the sliders 6. The two groups of telescopic rods 10 are symmetrically arranged left and right. Fixing plates 7 are fixedly connected to the tops of the telescopic rods 10. Rollers 81 are rotatably connected between the opposite sides of the fixing plates 7.

[0024] At first, the roller 81 is located at the rightmost end of the threaded rod 3. When it is necessary to laminate the liquid crystal display, place the liquid crystal display on the top of the base 1. Adjust the height of the right roller 81 through the telescopic rod 10 so that the roller 81 can contact the surface of the liquid crystal display. Tear off a corner of the film of the screen film, and then stick the film on the rightmost end of the liquid crystal display. Start the drive motor 2. The guide block 4 moves to the left through the threaded rod 3. The guide block 4 moving to the left causes the connecting rod 41 to drive the slider 6 to move to the left along the guide rail 5, thereby driving the roller 81 on the right fixing plate 7 to move to the left to press the film on the surface of the liquid crystal display. Manually tear off all the film while the roller 81 moves to the left. When the roller 81 moves to the leftmost end, the lamination is completed. Then start the drive motor 2 to reverse to make the roller 81 move to the right to reset. By using the roller 81 to press the surface of the liquid crystal display and the film, the film can be evenly pasted on the surface of the liquid crystal display, and this device can realize automatic lamination, avoiding bubbles generated between the film and the display screen caused by manual lamination. The setting of the telescopic rod 10 enables this device to laminate liquid crystal displays of different sizes, increasing the applicable range of this device.

[0025] As Figure 1 , Figure 4 and Figure 5 shown, it further includes an elastic member 11, a connecting plate 15 and a splitting knife 9. Elastic members 11 are fixedly connected to the tops of the left fixing plates 7. A splitting knife 9 is rotatably connected between the left fixing plates 7. Connecting plates 15 are fixedly connected to the tops of the elastic members 11. The elastic members 11 are used to assist the connecting plate 15 to reset. Both connecting plates 15 are slidably connected to the corresponding fixing plates 7. A roller 81 is rotatably connected between the front and rear connecting plates 15.

[0026] At first, the guide block 4 is located at the rightmost end of the threaded rod 3. When it is necessary to apply a film to the surface of the liquid crystal display, place the screen film between the two left rollers 81. Adjust the distance between the two left rollers 81 through the telescopic rod 10 to clamp the screen film by the left roller 81. Start the driving motor 2 to move the guide block 4 to the left. The guide block 4 moving to the left drives the roller 81 to move to the left through the connecting rod 41 and the slider 6. The splitting knife 9 separates the film and the membrane of the screen film. The membrane contacts the liquid crystal display and is pressed against the surface of the liquid crystal display by the right roller 81. The film will remain on the placement plate 12. Pull the screen film to drive the two left rollers 81 to rotate. After the liquid crystal display is finished with film application, take out the film, and then start the motor to reverse to move the three rollers 81 to the right to reset. It can realize no need for manual film tearing, avoid the film folding and sticking to the display surface due to uneven manual film tearing force, prevent the generation of bubbles between the display surface and the film, and at the same time, the integrated design of film tearing and film application can improve the working efficiency of this device.

[0027] As Figure 1 , Figure 4 and Figure 5 shown, it further includes a transmission motor 8. Transmission motors 8 are installed on the front sides of the fixing plates 7. The output shafts of the transmission motors 8 are fixedly connected to the fronts of the corresponding rollers 81. When starting the driving motor 2 to move the roller 81, start the transmission motor 8 at the same time to make the roller 81 rotate. The left roller 81 rotates to assist in separating the film in the screen film from the membrane, and the right roller 81 rotates to assist in sticking the membrane to the surface of the liquid crystal display, which can further improve the working efficiency of this device.

[0028] As Figure 1 , Figure 4 and Figure 5 shown, handles are fixedly provided on both the front and rear sides of the splitting knife 9. When it is necessary to rotate the angle of the splitting knife 9, just twist the handle of the splitting knife 9. Rotating the splitting knife 9 can prevent the splitting knife 9 from loosening and unable to cut the film and the membrane normally, and can also prevent the splitting knife 9 from contacting the roller 81 and thus damaging the roller 81.

[0029] AsFigure 1 and Figure 2 As shown in Figure 2 , it further includes a placement plate 12. The placement plate 12 is fixedly connected to the top of the base 1, and a square groove is formed on the top of the placement plate 12. When applying a film to the liquid crystal display, place the liquid crystal display in the placement plate 12, and then apply the film to the liquid crystal display. The placement plate 12 can ensure that the surface of the liquid crystal display is completely in contact with the roller 81, and the placement plate 12 can also protect the liquid crystal display from being worn by the base.

[0030] As Figure 1 and Figure 2 As shown in Figure 2 , it further includes an electric push rod 13 and a clamping plate 14. Two electric push rods 13 are provided on the left and right sides of the inner wall of the placement plate 12. The two electric push rods 13 are symmetrically arranged front and back. A clamping plate 14 is fixedly connected to the push rod of the front electric push rod 13 and the push rod of the rear electric push rod 13 respectively. After placing the liquid crystal display in the placement plate 12, start the electric push rod 13 to make the front and rear clamping plates 14 approach each other to clamp the liquid crystal display. After fixing the liquid crystal display, perform the film application operation on it. After the film application is completed, make the electric push rod 13 drive the clamping plates 14 to move away from each other to release the liquid crystal display, and finally take out the liquid crystal display from the placement plate 12 to complete a film application operation. The electric push rod 13 and the clamping plate 14 can fix the liquid crystal display during film application to prevent the liquid crystal display from shifting during film application, resulting in film application failure.

[0031] As Figure 1 , Figure 4 and Figure 5 As shown in Figure 5 , the middle part of the roller 81 is made of silica gel material. When the roller 81 contacts the liquid crystal display and the screen film, the silica gel on the roller 81 will press the film and the display tightly. Since the silica gel is relatively soft, it will not scratch the screen film.

[0032] As Figure 1 and Figure 2 As shown in Figure 2 , the bottom of the clamping plate 14 contacts the top of the placement plate 12. After starting the electric push rod 13 to clamp the liquid crystal display with the clamping plate 14, it prevents the roller 81 from contacting the clamping plate 14 and thus unable to press the liquid crystal display tightly for film application.

[0033] As Figure 1 , Figure 4 and Figure 5 As shown in Figure 5 , the three rollers 81 are all of the same size. It can reduce equipment investment and manufacturing costs, lower production costs, and at the same time ensure the consistency and quality of parts, and is also convenient for installing and adjusting this device.

[0034] As Figures 1-3As shown in the figure, buffer pads are provided on the opposite sides of the front and rear clamping plates 14 facing each other. When the electric push rod 13 is activated to clamp the display with the clamping plates 14, the buffer pads can protect the display and prevent it from being damaged by the extrusion of the clamping plates 14.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
