The laminating machine includes major mechanical parts such as unwinding device, gluing device, conveying and pressing device, and driving motor. The automatic laminating machine is mainly designed for the production characteristics of small displays and small touch components, and is one of the necessary equipment for the production of liquid crystal displays.
In the technical field of laminating machinery, it specifically refers to a laminating machine for laminating two-layer substrates. It is achieved by the following technical solution: the laminating machine includes a first substrate unwinding device for placing a first substrate, a glue spreading device, a second substrate unwinding device for placing a second substrate, and Preheating, conveying, heating and pressurizing laminating device, said preheating, conveying, heating and pressurizing laminating device includes a motor, a large heating wheel driven by the motor, and a pressing wheel, wherein the circumference of the heating wheel is formed with drying, heating, and conveying Zone and pressure bonding zone, in which the pressure roller is located at the periphery of the pressure bonding zone; the substrate placed on the first substrate unwinding device passes through the gluing device and enters the heating roller on the circumferential surface for drying and heating Zone, and pass between the pressing wheel and the heating wheel under the transportation of the heating wheel and the second substrate. The utility model has the advantages of environmental protection and energy saving, the entire process is compact, and has the advantages of saving space.
The automatic laminating machine is mainly designed for the production characteristics of small displays and small touch components. It is one of the necessary equipment for liquid crystal display production. It is used in the post-process production of liquid crystal display. Polarizers are attached to the front and back of the formed liquid crystal glass substrate according to the polarization angle. It is also suitable for various combination processes of touch components and window protection. It can complete the pressure-sensitive bonding of film/membrane, film/B glass substrate, film to acrylic panel and other different materials. It has high efficiency and convenient alignment. , The advantages of high product yield. It overcomes the shortcomings of bubbles, wrinkles, halo rings, water lines, etc. generated during manual bonding. While improving the intensity of manual labor, it also gets rid of the excessive dependence on the proficiency of personnel. The equipment is equipped with a multi-directional fine-tuning device, which is suitable for products of different shapes. With special fixtures, it can also fit products with irregular shapes such as arcs and diamonds. The upper and lower platforms are vacuum-adsorbed, equipped with international brand-name pneumatic components, precision lead screws and brand-name motors, and perform precise movements under the command of the central PLC. They are a powerful helper in the production process of optical products such as small modules and touch components.
Laminating machine winding accessories-magnetic powder brake is used in the winding system, including other uses such as buffer start, continuous sliding, tension control, etc. The magnetic powder brake has the advantages of smooth operation, no noise, large-scale control, fast response speed, etc., as well as the combination of its multiple uses. Part of the laminating machine adopts central unwinding, unwinding and automatic tension controller, unwinding wheel, paper trimming device, etc., so that the unwinding, laminating and rewinding of the laminating machine are more smooth and tidy, which greatly improves the product Quality and work efficiency.
The magnetic powder brakes of the laminating machine all use DC24V DC voltage, which is safe and reliable to use. According to the structure and design of the laminating machine, different specifications of magnetic powder brakes can be selected, such as specifications of 25Nm, 50Nm, 100Nm and 200Nm. In terms of installation, connect the output end of the magnetic powder brake of the laminating machine with the inflatable shaft and roller used for the winding material (connecting components are required), and input DC24 direct current to the magnetic powder brake. At the same time, with the tension controller, the use of tension adjustment is more precise, convenient and simple.
The rewinding group of the laminating machine adopts a magnetic powder brake, and the unwinding group adopts a magnetic powder clutch (double output shaft), one shaft (input shaft) is connected with the motor, and the other shaft (output shaft) is connected with the winding roller.
