[0003] Based on the above-disclosed technical solutions, a coating mechanism for a coating machine cannot simultaneously achieve high-efficiency coating of a single light guide plate and strip coating of the light guide plate, resulting in low production efficiency of coated light guide plates. Summary of the Invention

[0005] Specifically, this application provides a light guide plate coating film roll-up integrated machine, which adopts the following technical solution:

[0006] A light guide plate coating and rolling machine includes: a frame; an upper protective film placement mechanism mounted on the top of the frame for placing an upper protective film; a lower protective film placement mechanism mounted on the bottom of the frame for placing a lower protective film; a light guide plate feeding platform mechanism located below the upper protective film placement mechanism, including a light guide plate platform and a roller assembly; a coating shaft rolling mechanism, including a mounting plate, a coating shaft assembly, and a conveying assembly; the mounting plate is vertically mounted to the light guide plate platform, the conveying assembly and the roller assembly cooperate to drive the upper and lower protective films, and the coating shaft assembly is used to coat the light guide plate to obtain a coated light guide plate; a protective film cutting mechanism, including a cutting guide rail and a cutting assembly, the cutting guide rail driving the cutting assembly to cut the coated light guide plate to obtain a target coated light guide plate; and a receiving platform mechanism for receiving the target coated light guide plate.

[0007] By adopting the above technical solution, an upper protective film is placed in the upper protective film placement mechanism, and a lower protective film is placed in the lower protective film placement mechanism. After the upper and lower protective films are aligned and bonded, they are passed through the coating shaft assembly in the coating shaft rolling mechanism. The coating shaft assembly is used to coat the light guide plate with the upper and lower protective films to obtain a coated light guide plate. After the coating is completed, the film cutting guide rail of the protective film cutting mechanism drives the film cutting assembly to cut the coated light guide plate to obtain the target coated light guide plate. Each time a light guide plate is placed, a coating and cutting operation is performed to realize the single-piece strip coating of the light guide plate.

[0008] Optionally, the upper protective film placement mechanism is equipped with a first fixed horizontal plate, on which a first bearing roller for placing the upper protective film is installed, and upper protective film limiting blocks are provided on both sides of the first bearing roller; the lower protective film placement mechanism is equipped with a second fixed horizontal plate, on which a second bearing roller for placing the lower protective film is installed, and lower protective film limiting blocks are provided on both sides of the second bearing roller.

[0009] By adopting the above technical solution, the upper protective film is placed through the first bearing roller of the upper protective film and slides left and right through the upper protective film limiting block. The upper protective film can roll based on the first bearing roller to coat the upper surface of the light guide plate. The lower protective film is placed through the second bearing roller of the lower protective film and slides left and right through the lower protective film limiting block. The lower protective film can roll based on the second bearing roller to coat the lower surface of the light guide plate.

[0010] Optionally, the light guide plate platform is disposed on the outside of the frame; the roller assembly includes a roller bearing housing and a first transition roller, the roller bearing housing is embedded in one end of the light guide plate platform, and the first transition roller is mounted on the roller bearing housing.

[0011] By adopting the above technical solution, the lower protective film is connected through the first transition roller. The rotation of the first transition roller based on the roller bearing seat drives the lower protective film to slide on the light guide plate platform, thereby driving the light guide plate to perform film coating sliding finger-coated roller rolling mechanism for film coating.

[0012] Optionally, the coating shaft assembly includes an upper coating shaft, a lower coating shaft, a connecting rod, and a second transition roller. The connecting rod is used to connect with the upper protective film placement mechanism. The second transition roller cooperates with the upper coating shaft to apply an upper coating to the light guide plate, and the lower coating shaft cooperates with the first transition roller to apply a lower coating to the light guide plate.

[0013] By adopting the above technical solution, when the light guide plate is driven by the first transition roller to enter the coating shaft rolling mechanism, the upper coating shaft drives the upper protective film to roll and coat the upper surface of the light guide plate, and the lower coating shaft drives the lower protective film to roll and coat the lower surface of the light guide plate. This ensures that after being rolled by the upper and lower coating shafts, the light guide plate is covered between the upper and lower protective films.

The first power motor controls the first conveying timing belt to rotate, and the first timing pulley is connected to the lower rubber-coated shaft bearing to rotate the lower rubber-coated shaft.

[0015] Through the above technical solution, the first power motor drives the first conveyor to rotate the lower coating shaft, thereby coating the lower surface of the light guide plate. Based on the rotation of the lower coating shaft, the upper coating shaft can be rotated based on the lower protective film, thus realizing the coating operation of the upper protective film and the small protective film at the same time.

[0016] Optionally, the top of the mounting plate is provided with a clamping spring and a clamping adjustment screw, the clamping spring and the clamping adjustment screw cooperating with each other to adjust the wheel distance between the upper rubber-coated shaft and the lower rubber-coated shaft.

[0017] By adopting the above technical solution, the wheelbase between the upper and lower rubber-coated shafts is adjusted by using a pressure-reducing spring and a pressure-adjusting screw, thereby reducing the wheelbase between the upper and lower rubber-coated shafts and adjusting the pressure between them. This allows the upper rubber-coated shaft to rotate simultaneously when the lower rubber-coated shaft is rotated by the first power source, achieving double-sided coating on both sides.

[0018] Optionally, the cutting guide rail includes a second conveyor belt and a second power motor. The second conveyor belt is vertically mounted under the lower rubber-coated shaft, and the second power motor is mounted under the second conveyor belt.

The cutting slider is slidably mounted on the second conveyor belt, and the cutting blade holder is fixed on the cutting slider. The cutting blade holder is provided with a cutting blade, which is located between the upper rubber-coated shaft and the lower rubber-coated shaft, and is used to cut the coated light guide plate to obtain the target coated light guide plate.

[0019] By adopting the above technical solution, the diaphragm blade can be driven by the second power supply to separate the coated light guide plate and obtain the desired coated light guide plate.

[0020] Optionally, a start button and a pause button are provided on the outer side of the first transition roller, and the start button and the pause button are wiredly connected to the first power motor and the second power motor.

[0021] By adopting the above technical solution, the first power motor and the second power motor can be controlled by the start button and the pause button, thereby controlling the overall film coating progress.

[0022] Optionally, the start button controls the first power motor to operate, driving the lower coating shaft and pulling the upper coating shaft to rotate, performing the upper and lower coating on the light guide plate to obtain the coated light guide plate. The start button also controls the second power motor to operate, controlling the cutting slider to cut the coated light guide plate to obtain the target coated light guide plate.

[0023] By adopting the above technical solution, the first power motor is controlled by the start button to drive the lower coating shaft and rotate the upper coating shaft, thereby coating the light guide plate with film from top to bottom to form a coated light guide plate. At the same time, the start button also controls the second power motor to drive the film cutting slider to cut the coated light guide plate to obtain the target coated light guide plate. This realizes automatic coating and cutting, improves production efficiency, and ensures the quality and consistency of the light guide plate.

[0024] Optionally, the receiving platform mechanism includes a receiving platform and a lifting assembly. The receiving platform is installed behind the cutting guide rail. The lifting assembly includes a lifting guide column, a linear bearing, and a T-shaped lead screw. The lifting guide column is vertically connected to the receiving platform through the linear bearing. The T-shaped lead screw is vertically connected to the receiving platform, and a fixed handwheel is provided at the bottom of the T-shaped lead screw.

[0025] By adopting the above technical solution, the receiving platform mechanism uses a lifting component, including a lifting guide column, a linear bearing, and a T-shaped lead screw, which realizes the vertical lifting control of the receiving platform. The handwheel is used to reinforce the stability of the receiving platform mechanism, making the material receiving during the processing more accurate and efficient, improving production efficiency, reducing the difficulty of operation, and enhancing the overall efficiency of the production line.

[0026] In summary, this application includes a frame and mounted on the frame a light guide plate feeding platform mechanism, an upper protective film placing mechanism, a lower protective film placing mechanism, a coating roller rolling mechanism, a protective film cutting mechanism, and a receiving platform mechanism. The upper protective film placing mechanism is used to place the upper protective film, the lower protective film placing mechanism is used to place the lower protective film, the coating roller rolling mechanism is used to drive the upper and lower protective films to roll and transmit the film, thus coating the light guide plate to obtain a coated light guide plate.

The receiving platform mechanism is used to receive the target coated light guide plate. This application, based on the coating roller rolling mechanism and the protective film cutting mechanism, can simultaneously achieve high-efficiency coating of a single light guide plate and strip-type coating of the light guide plate, thereby improving the production efficiency of coated light guide plates.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] See Figure 1 and Figure 2 As shown, the integrated light guide plate coating and rolling machine can perform single-piece coating of light guide plates, facilitating manual assembly of light guide plates by production line workers; it can also perform strip coating of light guide plates, providing convenience for subsequent machine assembly of light guide plates. First, the upper and lower protective films are aligned and bonded, and then passed between the upper and lower adhesive-coating shafts in the adhesive-coating roller pressing mechanism 5.

[0039] See Figure 3 and Figure 4 As shown. After the light guide plate is produced by the injection molding machine, it is first cleaned by a dust collector, and then inspected by testing personnel. Once it passes inspection, the light guide plate is placed on the lower protective film 31 at the designated position on the worktable, as shown. Figure 3 , Figure 4As shown. Then, manually press the start button on the corresponding side. The PLC program is designed so that the set line length traveled by the rubber-coated shaft is determined by each press of the button on the lower rubber-coated shaft. The parameters set for different products are different. When the light guide plate passes through the upper and lower rubber-coated shafts along with the lower protective film 31, the upper protective film 21 is also simultaneously covered on the surface of the light guide plate. After passing through the upper and lower rubber-coated shafts 512, the light guide plate is covered between the upper and lower protective films. Because the rubber-coated shaft rolling mechanism 5 is equipped with a compression spring, the compression spring squeezes the upper rubber-coated shaft 511 onto the lower rubber-coated shaft 512. There is a certain pressure at the tangent point, which causes the air inside the upper and lower protective films and the light guide plate to be expelled when they pass through the rubber-coated rollers. The finished product is flat and there are no air bubbles between the protective films. When producing sheet products, each press of the start button activates the lower coating shaft motor to roll for a set length. After rolling a set length, the cutting motor runs once, cutting the protective film bonded together with the upper and lower parts using the cutting blade. Each time a light guide plate is placed, the protective film is cut once, and this is how the light guide plate sheet coating is performed. When the product needs to be made into a light guide plate strip, each time a light guide plate is placed, the start button is pressed, and the lower coating shaft motor moves once according to the set value. This process is repeated until the strip has covered the set number of sheets, at which point the protective film is cut to obtain the target coated light guide plate.
