Description

Technical Field

[0001] The invention relates to the technical field of lamination, in particular to a lamination device and a method for producing an anti-fog patch. Background Art

[0002] The lamination process of the anti-fog patch is to laminate the anti-fog layer and the bottom film together to prepare the anti-fog patch. The anti-fog layer material usually has oleophobic, hydrophobic, anti-fog and other properties, while the bottom film is used to protect the anti-fog layer for easy separation when used. The anti-fog layer material and the bottom film material are placed in the lamination equipment and are tightly fitted together by heating, pressurizing and other methods. During the lamination process, a certain temperature and pressure are maintained to promote adhesion between the materials.

[0003] When the anti-fog patch is ready to use, the user will tear off a layer of the bottom film, so that the anti-fog layer is exposed and can be attached to the helmet lens or other smooth surface that needs anti-fog. The separation of the bottom film allows the anti-fog layer to be attached cleanly and without damage, ensuring that its anti-fog effect can be fully exerted.

[0004] A Chinese patent with publication number CN116691116B discloses a composite material laminating device, including a main body, a bracket arranged on the main body, and a feeding mechanism arranged below the bracket; a moving plate is pushed by an electric push rod, thereby pushing the composite material placed in the guide groove, thereby solving the problem that the laminating device presses the composite material together under the strong pressure of an upper pressing plate and a lower pressing plate.

[0005] A Chinese patent with publication number CN117621600B discloses a lamination device and a lamination method for manufacturing photovoltaic laminates, including a workbench, a hot pressing device installed on the workbench, a pressurizing device and a gas supply device matched with an air guide ring installed on the workbench, so as to facilitate the auxiliary positioning of the surface protection layer through the auxiliary processing tube during the lamination process, and the protective gas can be injected into the surface protection layer through the auxiliary processing tube during the lamination process of the equipment, and the protective gas can be used to assist in the protection and gas sealing of the silicon solar cell panels.

[0006] The above-mentioned and similar prior arts can realize the lamination of plates to a certain extent, but the anti-fog sheet and the bottom film of the prior art need to be manually placed on the hot press table. Since the lamination process requires heating, the temperature of the hot press table is relatively high, and manual placement may easily injure the workers. In addition, the lamination between the anti-fog sheet and the bottom film needs to be aligned up and down, and usually additional equipment needs to be operated to proofread the positions of the two before lamination, which increases the workload and the complexity of processing. At the same time, most of the existing anti-fog patch lamination equipment is for single-volume processing. When large-scale production is required, the possibility of worker injury and proofreading errors is greatly increased during the long production process, which is not conducive to mass production.

[0051] Specifically, the workbench 11 can provide an opening space for the I-shaped groove 12, the I-shaped groove 12 can provide a placement space for the side panel 41, the side panel 41 can provide a stable support for the water tank 51, the water tank 51 can provide a placement space for the collection frame 52, and the water tank 51 can provide a placement space for the coolant.

[0052] The laminating method of the laminating equipment for producing anti-fog patches:

[0053] S1: Placing the patch 25 to be pressed. The staff first stacks the patch 25 to be pressed inside the placement hole of the loading plate 23;

[0054] S2: Loading of the patch 25 to be pressed. The staff starts the hydraulic cylinder 22 to drive the loading plate 23 to descend. The loading plate 23 squeezes the pressing rod 313 to move the hot pressing plate 37 downward to make room for the patch 25 to be pressed. The motor 28 is started to drive the screw 26 to rotate, so that the bottom stacked patch 25 to be pressed falls to the top of the hot pressing plate 37.

[0055] S3: lamination of the patch 25 to be pressed, the staff starts the telescopic rod 44 to extend and drive the laminating plate 31 to rotate, and the laminating plate 31 drives the patch 25 to be pressed to be squeezed and heated through the hot pressing plate 37;

[0056] S4: unloading, the staff starts the telescopic rod 44 to retract again, and the hot pressing plate 37 pushes out the laminated patch 25 during the rotation of the laminating plate 31.

[0057] Working principle: The initial state is as follows Figure 1 As described above, the staff first injects a large amount of cooling water into the water storage tank 51, and then places a large amount of anti-fog sheets 2501 and bottom sheets 2502 on the inner side of the placement hole, so that the anti-fog sheets 2501 and bottom sheets 2502 fall on the top of the rubber sheet 212 along the guide plates 24, and controls the hydraulic cylinder 22 to extend, so that the output end of the hydraulic cylinder 22 drives the loading plate 23 to move downward, and the loading plate 23 moves downward to squeeze the pressing rod 313 until it contacts the top of the protective shell 39;

[0058] When the loading plate 23 squeezes the pressing rod 313, the pressing rod 313 moves downward to squeeze the reset spring 312 and compress it. At the same time, the pressing rod 313 drives the side rod 314 to move downward, so that the side rod 314 drives the rotating column 315 to rotate 45° by utilizing the resistance effect with the slide groove 1 316. At this time, the rotating column 315 drives the slide groove 2 317 to rotate, so that the force-bearing rod 38 on the inner side of the slide groove 2 317 moves downward from the highest point of the slide groove 2 317 to reduce the height. The force-bearing rod 38 drives the bottom plate 35, the compression spring 36 and the hot pressing plate 37 to reduce the height, so that there is a height difference between the top of the hot pressing plate 37 and the top of the placement frame 34, providing a placement space for the patch 25 to be pressed;

[0059] Then the staff starts the motor 28 to drive the large gear 29 to rotate, and the large gear 29 drives the screw 26 to rotate by meshing with the small gear 27. The screw 26 drives the two threaded plates 211 of each group to move away from each other by the threaded action with the threaded plate 211, and the threaded plate 211 drives the rubber plate 212 to be stored in the inner side of the movable groove 210, so that the anti-fog sheet 2501 and the bottom film 2502 at the bottom of the placement hole lose support and fall to the inner side of the placement frame 34 and are located on the top of the hot pressing plate 37. The staff starts the motor 28 again to drive the large gear 29 to reverse, so that the threaded plate 211 drives the rubber plate 212 to clamp the penultimate anti-fog sheet 2501 and the bottom film 2502, and starts the hydraulic cylinder 22 to drive the loading plate 23 to move upward and reset. At the same time, the pressure rod 313 moves upward and resets under the action of the reset spring 312. During the reset process, the rotating column 315 rotates 45° again, and the force rod 38 moves to the lowest point of the second slide groove 317;

[0060] After the staff applies adhesive on the top of the bottom film 2502 on the top of the hot pressing plate 37, the telescopic rod 44 is started to extend, so that the output end of the telescopic rod 44 drives the push block 45 to move downward, and the push block 45 drives the support rod 1 32 to move downward. At the same time, the guide spring 46 pushes the support rod 1 32 to move in the direction of the limit groove 43 under its own elastic force, and the support rod 1 32 and the support rod 2 33 move along the inner side of the track hole 42. When the telescopic rod 44 drives the support rod 1 32 to move to the inner side of the bottom wall of the track hole 42, the support rod 1 32 and the support rod 2 33 drive the two laminates 31 to rotate to the limit groove 43. The position of the positioning slot 43 is parallel to each other. At this time, the placement frames 34 on the top of the two laminates 31 fit together, driving the anti-fog sheet 2501 and the bottom film 2502 to fit and squeeze together. The hot pressing plate 37 heats and presses to perform the lamination process. At the same time, the pressure rods 313 on the top of the two laminates 31 squeeze each other, causing the rotating column 315 to rotate again, and the force-bearing rod 38 moves upward along the lowest point of the slide groove 317, thereby driving the bottom plate 35 to move upward. Since the hot pressing plate 37 drives the anti-fog sheet 2501 and the bottom film 2502 to squeeze each other, the bottom plate 35 squeezes the compression spring 36 to shrink and deform, and the lamination process is as follows: Fig. 9 As shown;

[0061] Start the telescopic rod 44 again to retract, and the telescopic rod 44 drives the laminate 31 to rotate and reset. The pressure rod 313 and the rotating column 315 are also reset to the initial state. During the resetting process, the placement frames 34 on the top of the two laminates 31 move away from each other, so that the compression spring 36 recovers due to its own elastic force when the external force is lost. The compression spring 36 drives the hot press plate 37 to move upward, and then the hot press plate 37 pushes the laminated anti-fog patch out of the inner side of the placement frame 34. Because the laminate 31 is still in a tilted state when the two placement frames 34 are separated, the anti-fog patch passes through the two laminates 31 and falls downward into the water tank 51, and is collected in the collection frame 52. After the laminated patch 25 to be pressed in the water tank 51 is cooled, the laminated anti-fog patch is taken out through the collection frame 52.
