Description

Technical Field

[0001] The present application relates to the technical field of film laminating equipment, and specifically to a large-sized ITO film laminating device. Background Art

[0002] ITO film is an n-type semiconductor material with high electrical conductivity, high visible light transmittance, high mechanical hardness and good chemical stability. At the same time, due to the plasma vibration phenomenon of carriers in the near-infrared region, reflection occurs, so the light transmittance of ITO film in the near-infrared region is also very low. However, the transmittance of ITO film in the visible light region is very good. Due to the specific physical and chemical properties of the material itself, ITO film has good electrical conductivity and high light transmittance in the visible light region.

[0003] The Chinese utility model patent with publication number CN215970566U discloses a laminating device for ITO conductive film. It is done by installing a conductive film roll in a laminating assembly and placing it between the laminating assembly and the substrate. The conductive film on the conductive film roll is then pulled out through the laminating assembly, and the support assembly with the laminating assembly installed inside is driven to move by a screw module, so that the conductive film is squeezed by the laminating assembly to make it adhere to the surface of the substrate. After the laminating is completed, the two drive assemblies are started to push the cutting blades to cut the conductive film, and the laminating to the substrate is completed. Multiple laminating processes can be performed in sequence, saving time and labor while greatly improving processing efficiency, and having strong practicality. However, the laminating roller has a fixed height and can only laminar workpieces of a single height, which is less practical.

[0004] Therefore, the present application provides a large-sized ITO film laminating device to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a large-sized ITO film laminating device, such as Figure 1-3As shown, the laminating device includes a conveyor belt 1, a feed roller 2 rollingly mounted on the conveyor belt 1, and a material guide mechanism 3 fixedly mounted on the conveyor belt 1. A pressing mechanism 4 is fixedly mounted on the conveyor belt 1 at the output end of the material guide mechanism 3:

[0024] The material guide mechanism 3 includes two symmetrical mounting blocks 31 fixedly mounted on the conveyor belt 1. A driving roller 32 and a driven roller 33 are rotatably mounted between the two mounting blocks 31. One end of the driving roller 32 passes through the side wall of the mounting block 31 and a driving motor 34 is fixedly mounted at the end.

[0025] The pressing mechanism 4 includes an arch frame 41 fixedly mounted on the conveyor belt 1, on which a cylinder 42 is fixedly mounted, the telescopic end of the cylinder 42 passes through the outer wall of the arch frame 41 and extends into the interior of the arch frame 41 and a lifting plate 43 is fixedly mounted at the end, on which a receiving plate 44 is movably mounted, and on which a pressure roller 45 arranged toward the surface of the conveyor belt 1 is rotatably mounted.

[0026] During use, the ITO film on the feed roller 2 is guided between the active roller 32 and the driven roller 33, the workpiece is placed on the conveyor belt 1, the drive motor 34 is started, the active roller 32 is driven to rotate, and the ITO film is extruded to cover the surface of the workpiece. At the same time, the cylinder 42 is started to drive the lifting plate 43 to move downward in the arch 41, and the pressure roller 45 on the receiving plate 44 is pressed onto the ITO film on the surface of the workpiece, thereby pressing the ITO film to play the role of bonding and air bubble removal. The height of the pressure roller 45 is adjustable and can adapt to workpieces of different sizes and heights, and the use effect is better.

[0027] Specifically, a brush strip 46 is fixedly mounted on the receiving plate 44 on one side of the pressure roller 45. The length of the brush strip 46 is greater than the height of the pressure roller 45 from the receiving plate 44. When in use, after the ITO film attached to the surface of the workpiece is pressed, the brush strip 46 cleans the surface of the ITO film, further improving the cleanliness of the equipment.

[0028] More specifically, the arch 41 has symmetrically arranged lifting cavities 47 at both ends. Slide rods 48 are fixedly installed in the lifting cavities 47. The ends of the lifting plate 43 extend into the lifting cavities 47 and are slidably connected to the slide rods 48. During use, the ends of the lifting plate 43 move up and down on the slide rods 48 in the lifting cavities 47, making the movement more stable and ensuring more uniform and reliable pressure on the workpiece surface.

[0029] Furthermore, two connecting rods 49 are fixedly mounted at both ends of the receiving plate 44, extending through the lifting plate 43. Springs 410 are sleeved on the connecting rods 49 between the lifting plate 43 and the receiving plate 44. During operation, the receiving plate 44 follows the lifting plate 43 downward. When contacting the workpiece surface, the pressure roller 45 pushes the receiving plate 44 upward, compressing the springs 410. This gives the pressure roller 45 a certain degree of elasticity, allowing for closer contact with the workpiece and a better pressing and laminating effect.

[0030] Example 2

[0031] Unlike Example 1, during lamination, the ITO film may have defects caused by production or transportation that are difficult to detect. If these defects are not removed, they may affect subsequent use. To this end, the lamination device also includes a detection mechanism 5. The detection mechanism 5 includes a dark box 51 fixedly mounted on the conveyor belt 1 and located between the feed roller 2 and the material guide mechanism 3. A visual inspection device 52 is fixedly mounted in the dark box 51. Filling lights 53 are fixedly mounted around the visual inspection device 52 in the dark box 51. During use, the filling lights 53 are turned on, the ITO film on the feed roller 2 is introduced into the dark box 51, and then connected to the active roller 32. The active roller 32 drives the ITO film to move, and the visual inspection device 52 inspects the surface of the ITO film in the dark box 51, preventing the use of defective products and improving quality.

[0032] Furthermore, leveling rollers 54 are fixedly installed at both ends of the dark box 51 .

[0033] During use, the ITO film on the feed roller 2 is guided to the bottom of the two leveling rollers 54 and then to the active roller 32, so that the ITO film is stretched into a horizontal plane under the two leveling rollers 54, which is more convenient and accurate when inspected by the visual inspection equipment 52.

[0034] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
