Description

Technical Field

[0001] This utility model relates to the technical field of PET film lamination devices, specifically a PET film lamination device. Background Technology

[0002] Polyethylene terephthalate (PET) film is widely used in precision lamination processes in display panels, touch modules, photovoltaic cells, and electronic packaging due to its excellent optical properties, mechanical strength, chemical resistance, and thermal stability. With the trend towards thinner and more flexible consumer electronics products and the rapid development of the new energy industry, the market demand for high-precision, high-efficiency lamination of PET film with materials such as glass, metal, and flexible substrates is increasing daily. In existing PET film lamination processes, when laminating PET films onto sheets, mechanical equipment or manual labor is often used to place the sheets into a conveyor frame for transport. When laminating PET films with special patterns on their surfaces, the sheets are prone to tilting after loading, causing the relative positions of the PET film and the sheet to shift during the lamination process. This results in defects such as tilting and misalignment of the laminated pattern, seriously affecting product yield and quality, and making it difficult to meet the production requirements for high-precision lamination. Therefore, we have proposed a PET film lamination device to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a PET film laminating device to solve the problem mentioned in the background art that the PET film laminating device causes the laminated pattern to be tilted due to the tendency of the board to tilt after loading.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a technical solution, a PET film laminating device, including a conveyor frame 1, and multiple sets of feeding rollers 2 are provided inside the conveyor frame 1; The conveyor frame 1 has two centering plates 3 inside, which are connected to the two centering plates 3 via a drive assembly 4. The top of the conveyor frame 1 has two fixing plates 5, and a feeding roller 6 is connected between the two sets of fixing plates 5. The feeding roller 6 is detachably connected to the fixing plates 5. Each of the two sets of fixing plates 5 has a locking plate 13 hinged to its top, and a locking rod 14 is threaded to one end of each of the two sets of locking plates 13. The locking rod 14 is threaded to the fixing plate 5 on the same side. A pressure roller 7 is located between the two sets of fixing plates 5, and a driven roller 15 is connected between the right sides of the two sets of fixing plates 5. The fixing plates 5 are connected to the pressure roller 7 via an adjustment assembly 17. Each of the two sets of fixing plates 5 has a sliding mounting block 16 inside, which is rotatably connected to the pressure roller 7 on the same side. The adjustment assembly 17 includes... The conveyor frame 1 includes a first lead screw 171 and a guide rod 172. Both sets of fixed plates 5 are equipped with guide rods 172. The two sets of guide rods 172 are slidably connected to the mounting blocks 16 on the same side. The first lead screw 171 is rotatably inserted inside the fixed plate 5 on the front side of the conveyor frame 1. The first lead screw 171 is threadedly connected to the mounting blocks 16 on the same side. The top of the conveyor frame 1 is equipped with a cutting assembly 8. The cutting assembly 8 includes a drive groove 801, a second lead screw 802 and a guide block 803. The top of the conveyor frame 1 is equipped with a drive groove 801. The second lead screw 802 is rotatably inserted inside the drive groove 801. The surface of the drive groove 801 is slidably equipped with a guide block 803. The guide block 803 is threadedly connected to the second lead screw 802. A cutting blade 18 is detachably installed on the side wall of the guide block 803. At this time, the board moves above the pressing roller 7, and simultaneously the film roll on the surface of the upper feeding roller 6 releases the film and, together with the guide rail 9, enters below the pressing roller 7. The pressing roller 7 then bonds the film and the board together. Simultaneously, the motor drives the pressing roller 7 to rotate, resulting in a better bonding effect between the film and the board. During use, the handle at the bottom of the first lead screw 171 at the bottom of the conveyor frame 1 can be rotated, causing the first lead screw 171 to drive the mounting block 16 to slide inside the mounting plate. After the mounting block 16 slides above the guide rod 172, the height of the pressing roller 7 can be adjusted. The section is designed to accommodate boards of different thicknesses. During use, the boards are continuously fed in. After two adjacent sets of boards are bonded together, they are connected by a film. The film needs to be cut. At this time, the second lead screw 802 can be rotated by the motor. The second lead screw 802 drives the guide block 803 to slide above the drive groove 801, so that the guide block 803 drives the cutting blade 18 to move and cut the boards apart. Since the drive groove 801 is inclined, it is not necessary to stop the board feeding during the cutting process. Cutting can be carried out synchronously during the feeding process. The drive assembly 4 includes a rotating shaft 401, a drive gear 402, and a rack 403. The drive gear 402 is mounted on the rotating shaft 401. Guide rails 9 are provided on both sides inside the conveyor frame 1. A rack 403 that meshes with the drive gear 402 is slidably mounted on both guide rails 9. The top of both racks 403 is connected to one end of the bottom of the center plate 3 on the same side. The bottom of the other end of the center plate 3 is slidably connected to the guide rails 9 through a driven block 10. A cylinder 11 is provided at the bottom of the conveyor frame 1. A drive block 12 is provided at the output end of the cylinder 11. The drive block 12 slides through the conveyor frame 1 and is connected to the bottom of a single rack 403. In use, the sheet material to be laminated with PET film needs to undergo surface treatment through a processing procedure. Then, it is placed into the conveyor frame 1 by a feeding device or manually. The sheet material is conveyed by the rotation of multiple sets of feeding rollers 2 inside the conveyor frame 1. The feeding rollers 2 are driven by an external drive device to achieve synchronous rotation of multiple sets of feeding rollers 2. During the feeding process, the cylinder 11 pushes the drive block 12 to slide inside the conveyor frame 1. At the same time, the drive block 12 drives a single rack 403 to slide above the guide rail 9, so that the rack 403 drives the drive gear 402 to rotate. The drive gear 402 drives the rack 403 on the other side to move. At this time, the two sets of racks 403 respectively drive the centering plate 3 on the same side to move. At the same time, the bottom end of the centering plate 3 on the other side slides synchronously above the guide rail 9 through the driven block 10. After the centering plates 3 on both sides move to the center, the sheet material is centered, preventing the sheet material from shifting.

[0015] Working principle: When using the PET film laminating device, the sheet material to be laminated with PET film needs to undergo surface treatment before being placed into the conveyor frame 1 via a feeding device or manually. Multiple sets of feeding rollers 2 inside the conveyor frame 1 transport the sheet material. The feeding rollers 2 are driven by an external drive device to achieve synchronous rotation of multiple sets of feeding rollers 2. During the feeding process, the cylinder 11 pushes the drive block 12 to slide inside the conveyor frame 1, and simultaneously the drive block 12 drives a single rack 403 on the guide rail 9. The sliding motion causes the rack 403 to drive the drive gear 402 to rotate, which in turn drives the rack 403 on the other side to move. At this time, the two racks 403 respectively drive the centering plate 3 on the same side to move. Simultaneously, the bottom end of the centering plate 3 on the other side slides synchronously above the guide rail 9 via the driven block 10. After the centering plates 3 on both sides move to center the plate, they center the plate and prevent it from shifting. At this time, the plate starts to move above the pressing roller 7, and at the same time, the film roll on the surface of the upper feeding roller 6 releases the film and enters the guide rail 9 synchronously with the plate. Below the pressing roller 7, the film and sheet are bonded together by the pressing roller 7. Simultaneously, the motor drives the pressing roller 7 to rotate, resulting in a better bonding effect between the film and sheet. During use, the handle at the bottom of the first lead screw 171 at the bottom of the conveyor frame 1 can be rotated, causing the first lead screw 171 to drive the mounting block 16 to slide inside the mounting plate. After the mounting block 16 slides above the guide rod 172, the height of the pressing roller 7 can be adjusted to accommodate sheets of different thicknesses. Sheets are continuously fed during use, and adjacent sets of sheets are connected by a film after bonding. Together, the film needs to be cut. At this time, the second lead screw 802 can be driven by the motor to rotate. The second lead screw 802 drives the guide block 803 to slide above the drive groove 801, so that the guide block 803 drives the cutting blade 18 to move and cut the plates apart. Since the drive groove 801 is inclined, it is not necessary to stop the plate feeding during the cutting process. Cutting can be carried out synchronously during the feeding process, thereby completing a series of tasks. The contents not described in detail in this specification are the prior art known to those skilled in the art.

[0016] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
