[0040] like Figures 1-2 As shown, this utility model provides a coating machine, including a frame 8, and an unwinding unit 1, a cleaning unit 2, a bonding unit 3, a drying unit 4, a laminating unit 5 and a winding unit 6 arranged sequentially within the frame 8. The unwinding unit 1 and the cleaning unit 2 are both provided with two layers.

[0041] The unwinding unit 1 performs the outer film peeling and unwinding operations on both optical films. Then, the surface of the optical film with the outer film peeled off is cleaned in the cleaning unit 2 to prevent dust from settling on the surface. Next, the two optical films are bonded together in the bonding unit 3 and coating is injected between them. The bonded optical films are then immediately dried and cured in the drying unit 4 to prevent poor bonding. Subsequently, the composite unit 5 applies dustproof film to the top and bottom surfaces of the bonded optical films to prevent dust from settling on the composite film surface. Finally, the winding unit 6 performs the winding operation of the finished product.

[0042] The unwinding unit 1 includes a film-tearing device 101, an unwinding device 102, and a web-correcting device 103, which are sequentially installed on the frame 8. The unwinding device 102 unwinds the optical film, while the film-tearing device 101 tears the outer film of the single-layer optical film, and the web-correcting device 103 performs a web-correcting operation. The web-correcting device 103 is a purchased existing product.

[0043] Please refer to this carefully. Figure 3 The film-tearing device 101 includes a support frame 1011 and a film-tearing roller 1013 movably mounted on the support frame 1011 via a motor 1012. During operation, the outer film of the optical film roll head is manually torn open and simultaneously wound onto the film-tearing roller 1013. Then, the motor 1012 is turned on, thereby driving the film-tearing roller 1013 to automatically perform the film-tearing operation while the unwinding device 102 is unwinding.

[0044] Please refer to this carefully. Figure 2The cleaning unit 2 includes a receiving device 201, a tension device 202, and a cleaning device 203, which are sequentially installed on the frame 8. After the unwinding device 102 unwinds a roll, the receiving device 201 fixes the optical film, which is then manually cut using a cutting knife. The tension device 202 is used to control the up-and-down movement of the film material to control the tension intensity of the entire film material. Finally, the film material is cleaned by the cleaning device 203.

[0045] Please refer to this carefully. Figure 4 The receiving device 201 includes a receiving frame 2011. Cylinders 2012 are symmetrically installed on both sides of the receiving frame 2011. The symmetrical cylinders 2012 are connected by a pressure plate 2013. The optical film passes through the bottom of the pressure plate 2013. When the optical film needs to be cut, the cylinders 2012 are opened, thereby driving the pressure plate 2013 to press the film material.

[0046] Furthermore, the receiving rack 2011 is also equipped with an adjustment button 2014, which is used to control the lifting and moving of cylinder 2012.

[0047] Please refer to this carefully. Figure 5 The tension device 202 includes brackets 2021 symmetrically mounted on the frame 8. Each bracket 2021 is equipped with a second cylinder 2024. The two ends of the tension roller 2022 are movably mounted on the second cylinder 2024 through hinge seats 2023, and the second cylinder 2024 controls the tension roller 2022 to move up and down.

[0048] Please refer to this carefully. Figure 6 The cleaning device 203 includes a cover 2031, in which cylinders 2023 and cleaning components are symmetrically installed vertically, and transition rollers 20310 are symmetrically installed horizontally.

[0049] The cleaning assembly includes a U-shaped structure formed by a fixed block 2034, a fixed column, and a base 2036, as well as a movable block 2033 and a movable seat 2037 fitted on the fixed column. A movable roller 2035 is movably mounted on the movable block 2033 via a motor, and a rubber roller 2038 is movably mounted on the movable seat 2037. The rubber roller 2038 is positioned closer to the film material than the movable roller 2035. Springs 2039 are installed between the movable block 2033 and the movable seat 2037, and between the movable seat 2037 and the base 2036. When the cylinder 2032 operates, it pushes the movable roller 2035 to move up and down, thereby driving the rubber roller 2038 to move up and down. The rubber roller 2038 is used to stick dust on the optical film.

[0050] The optical film passes under the transition roller 20310, and then the cylinder 2023 pushes the adhesive roller 2038 up and down to stick the dust on the optical film. At the same time, the motor drives the moving roller 2035 to rotate, which in turn drives the adhesive roller 2038 to rotate, avoiding repeated sticking in the same position with the adhesive roller.

[0051] Please refer to this carefully. Figure 7 and Figure 8 The bonding unit 3 is equipped with a bonding device 301, which includes a bonding frame 3011, a pressing roller 3018 symmetrically mounted in the bonding frame 3011 via a cylinder 3013 and a moving plate 3012, and a flattening roller 30110 in contact with the pressing roller 3018. The flattening roller 30110 is movably mounted on the moving plate 3012 via a cylinder 3019. A limiting plate 3015 is movably mounted on the bonding frame 3011 via a manual screw assembly 3014. A pipe fixing block 3017 is movably mounted on the limiting plate 3015 via an electric slide rail 3016. The pipe is fixed on the pipe fixing block 3017. The pipe is used to inject coating between two layers of optical film. The limiting plate 3015 is used to prevent coating from falling into the device. The manual screw assembly 3014 is used to adjust the position of the limiting plate 3015.

[0052] The two optical films first pass through the bonding area between the flattening roller 30110 and the pressing roller 3018, and then converge at the bonding area of ​​the two pressing rollers 3018. The confluence is driven by the electric slide rail 3016 to move the pipe and bring in the coating, thus forming a composite film. The flattening roller 30110 flattens the optical film to avoid wrinkles during the lamination process.

[0053] Drying unit 4 is equipped with dryer 401, which is used to dry and cure the composite film.

[0054] Please refer to this carefully. Figure 9 The composite unit 5 is equipped with a composite device 501, which includes a dustproof film roll 1 5011 and a dustproof film roll 2 5013 movably mounted on the frame 8, and a composite frame 50110 mounted on the frame 8. The composite frame 50110 is movably mounted in sequence with a transition roller 3 5019, a push roller 5018, a flattening roller 2 5016, a push roller 5014, and a transition roller 2 5012. The push roller 5018 is movably mounted on the composite frame 50110 via a cylinder 6 5017. When the cylinder 6 5017 pushes the push roller 5018 to move, it can drive the flattening roller 2 5016 to flatten the dustproof film on the composite film. At the same time, the push roller 5014 is movably mounted on the composite frame 50110 via a motor 2 5015.

[0055] To prevent dust from getting on the upper and lower surfaces of the composite film during transportation, the composite device 501 lays a layer of dustproof film on both the upper and lower surfaces of the composite film. First, the dustproof film is rolled out, and then it passes through the transition rollers to reach the upper and lower surfaces of the composite film respectively, and finally they are combined to form the finished product.

[0056] The winding unit 6 is equipped with a tension device 202 and a winding device 601 for winding the final product.

[0059] Control panel 7 includes a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the manufacturing process. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls allow these actuators to operate according to the required steps.

[0060] The working principle of this utility model is as follows:

[0061] First, the film-tearing device 101 in the unwinding unit 1 tears the outer film of the two optical films, while the unwinding device 102 unwinds the film. Then, in the cleaning unit 2, the optical film passes through the receiving device 201, tension device 202, and cleaning device 203 in sequence. The cleaning device 203 cleans the surface of the optical film with the outer film torn off. After that, in the laminating unit 3, the laminating device 301 laminates the two optical films together and injects coating between them. Then, the laminated optical film is immediately dried and cured in the dryer 401 in the drying unit 4. Then, the laminating device 501 in the laminating unit 5 applies a dustproof film to the upper and lower surfaces of the composite film to prevent dust from settling on the surface of the composite film. Finally, the winding unit 6 winds up the finished product.

[0062] This device adds a cleaning unit 2 and a laminating unit 5 compared to existing coating machines, thereby ensuring the cleaning power during the laminating film production process and further guaranteeing product quality.
