Description

Technical Field

[0001] The present invention relates to the technical field of automatic lamination, and more specifically, to a sealing foam and its production process. Background Art

[0002] The sealing foam plays a crucial protective role in laptops: by filling the gaps in areas such as the screen, hard drive, and motherboard, it realizes functions such as dust and water prevention, shock buffering, electromagnetic shielding, and heat dissipation optimization. Its lightweight and compressible characteristics ensure a thin and light structure while effectively blocking noise and extending the device's lifespan, making it a core protective material for enhancing laptop reliability, durability, and user experience.

[0003] In the production process of the sealing foam, a double-station lamination device is used to precisely match different materials of films with the foam, and through a lamination process, the two are closely laminated. Subsequently, a stamping operation is carried out with the help of a stamping device, and finally, it is formed into individual sealing foams. However, in the actual use of the double-station lamination device, when the film and the foam are conveyed on the conveying components, it is extremely easy to have an offset phenomenon and cannot be stably in the middle position of the conveying roller, which will undoubtedly have an adverse impact on the lamination quality of the sealing foam.

The bottom film unwinding roller is arranged on the frame for unwinding the bottom film; the film to be laminated unwinding and peeling mechanism is used for unwinding the film to be laminated and separating the film to be laminated and the waste film; the UVW adjustment platform includes: a base and a moving seat that can move relative to the base. The base is arranged on the frame, and the film to be laminated unwinding and peeling mechanism is arranged on the moving seat. The UVW adjustment platform is used to adjust the position of the film to be laminated unwinding and peeling mechanism relative to the frame; the vision recognition module is arranged on the frame for collecting the position data of the film to be laminated and the bottom film, and controlling the movement of the moving seat of the UVW adjustment platform according to the collected position data to align the film to be laminated and the bottom film; the lamination mechanism is arranged on the frame for laminating the aligned film to be laminated and the bottom film; the above patent can prove the defects existing in the prior art.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem in the prior art that when the film and foam are conveyed on the conveying component, the film and foam are easily deviated and cannot be stably located in the middle position of the conveying roller, which will undoubtedly have an adverse effect on the laminating quality of the sealing foam, the rib plate is pushed so that the rib plate is turned upward with a positioning hinge, and the elastic cover on the outer wall of the conveying roller is stretched to expand in a trumpet shape, and the film conveyed above the conveying roller is moved from both sides to the middle, so that the film is corrected and adjusted, so that the conveyed film can be corrected and adjusted during the production process of the sealing foam, thereby improving the quality of the sealing foam production;

[0022] 2. The bevel rod is pushed to move by the displaced fixed ring plate. With the cooperation of the movable hinge and the positioning hinge, the horizontal state between the bevel rod and the rib plate changes, the outer arc plate is separated from the state of overlapping with the rib plate, and the knife plate is away from the rib plate and contacts the conveyed film, so that the edge of the conveyed film in the sealing foam production process can be cut, thereby improving the efficiency of sealing foam production;

[0023] 3. The scraper is pushed to move by the expanded double-pass airbag, so that the scraper protrudes from the transverse groove of the outer wall of the conveying roller and contacts the film conveyed on the surface of the conveying roller. As it rotates, the stains and grease on the surface of the film are cleaned. After the double-pass airbag shrinks, the scraper moves down, and the impurities on the side of the scraper are unable to pass through the transverse groove and remain on the surface of the conveying roller. In this way, the scraper is cleaned, so that the film conveyed in the sealing foam production process can be scraped and cleaned, and the stains and grease attached to the surface are cleaned, thereby improving the quality of its sealing foam production;

After the bevel rod is pushed, the outer arc plate moves away from the rib plate with the cooperation of the movable hinge and the positioning hinge, driving the knife plate and the film to perform cutting operations. During the deviation correction and adjustment process, after the bevel rod is pushed, the rib plate flips upward with the cooperation of the positioning hinge and the movable hinge, and one end of the rib plate moves away from the transmission roller to expand the elastic cover, pushing the film on the outer wall of the transmission component to move toward the middle, so that it can be flexibly switched between the trimming structure and the deviation correction structure, thereby improving the efficiency of sealing foam production.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As described in the background art, during the actual use of the double-station laminating equipment, when the film and the foam are conveyed on the transmission component, it is very easy to have an offset phenomenon and cannot be stably in the middle position of the conveying roller, which will undoubtedly have an adverse impact on the laminating quality of the sealing foam.

[0042] To solve this technical problem, the present invention provides a sealing foam and its production process, which are applied to the field of automatic laminating technology.

[0043] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0044] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0045] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 A production process of a sealing foam, which uses a double-station laminating machine for the lamination operation of the film. The double-station laminating machine includes a laminating device 1 and a pressing component 9. The laminating device 1 is provided with a transmission component 10 for single-piece film transmission. The transmission component 10 includes a deviation correction component 6 for the film conveying process. The deviation correction component 6 includes a plurality of rib plates 613 evenly distributed circumferentially at both ends of the transmission component 10. An elastic cover 614 for expanding and correcting the deviation during the transmission process of a single-piece film is arranged between the plurality of rib plates 613 on the same side. A positioning hinge 606 is arranged at one end of the rib plate 613 close to the middle of the transmission component 10. The specific production process includes the following steps: S1. The foam and the blue protective film are introduced by the double-station device, passed through the transmission component 10 and introduced into the pressing component 9. During the pressing process, the rib plate 613 is flipped with the positioning hinge 606 and unfolds in a trumpet shape, pushing the film to move towards the middle of the transmission component 10 to correct the foam and the blue protective film during the transmission and pressing process, and enter the pressing component 9 for alignment and pressing; S2. With the PET surface of the foam facing up and the blue protective film input at the bottom, then the lower double-sided adhesive and the lower red release film are sequentially laminated and die-cut. After completion, it is laminated with the lower green protective film; S3. After the lamination, it is introduced, and the red release film is removed by the green tape, and then transmitted to the second station. The inner hole waste is removed by the lower transparent release film using the release surface on the reverse side, and then the lower red release film is covered for lamination and derivation for die-cutting operation; S4. The lower white release film and the lower transparent protective film are sequentially torn off from its surface, and the tape is flipped and die-cut; S5. Transmitted to the station, and the peripheral waste of the product is collected.

[0047] By pushing the rib 613, the rib 613 is flipped upward with the positioning hinge 606, stretching the elastic cover 614 on the outer wall of the transmission roller 701 to expand in a trumpet shape, and moving the film that is above the transmission roller 701 for material conveying from both sides to the middle, so as to correct the deviation of the film, thereby being able to correct the deviation of the transmitted film during the sealing foam production process, thereby improving the quality of sealing foam production.

[0048] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, a movable hinge 615 is provided at one end of the rib plate 613 away from the positioning hinge 606, and an angled rod 611 is provided on the other side of the movable hinge 615. A fixed ring plate 608 is provided in the middle of the four angled rods 611 on the same side, and a limiting groove 609 is provided on the outer wall of the fixed ring plate 608 for limiting the angled rod 611. A cutting component 7 is provided on one side of the angled rod 611, an internal threaded cylinder 610 is fixedly installed in the middle of the fixed ring plate 608, and a threaded rod 602 is movably installed on the inner wall of the internal threaded cylinder 610, and a central axis rod 607 is fixedly connected between the two threaded rods 602. A cleaning component 8 is provided on the outer wall of the central axis rod 607, and the threaded rod 602 is rotated to drive the fixed ring plate 608 with the internal threaded cylinder 610 to move, thereby pushing the four angled rods 611, and using the movable hinge 615 and the positioning hinge 606 as a transmission structure to make the angled rod 611 flip over, thereby expanding the elastic cover 614 in a trumpet shape.

[0049] Further, such as Figure 5 and Figure 6 As shown, the threaded rod 602 is fixedly connected to a positioning rod 601 at one end away from the central axis rod 607, a bearing 604 is provided on the outer wall of the positioning rod 601, the bearing 604 is provided with a positioning cylinder 603, and the positioning cylinder 603 is provided with a plurality of protective plates 605 at one end close to the central axis rod 607, which cooperate with the positioning rod 601 through the bearing 604 to transmit the power of the positioning gear 12 to the threaded rod 602, so that the threaded rod 602 rotates.

[0050] Example 2, the sealing foam production process provided in Example 1 is further optimized, specifically, as follows Figure 3 , Figure 4 , Figure 5 and Figure 8As shown in the figure, the cutting component 7 includes a limiting arc plate 612 fixedly installed at one end of the bevel rod 611. An outer arc plate 702 is provided at one end of the limiting arc plate 612 away from the bevel rod 611. A knife plate 703 for cutting the film is provided at one end of the outer arc plate 702 close to the rib plate 613. A transmission roller 701 for guiding and transmitting the film is provided between two groups of positioning hinges 606. When the threaded rod 602 rotates, with the cooperation of the bearing 604, neither the positioning cylinder 603 nor the transmission roller 701 rotates following the threaded rod 602. The fixed ring plate 608 is engaged with the rotating threaded rod 602 by the internal thread cylinder 610, pushing the bevel rod 611 in the limiting groove 609. With the cooperation of the movable hinge 615 and the positioning hinge 606, the angle between the bevel rod 611 and the rib plate 613 gradually decreases, driving the knife plate 703 connected by the outer arc plate 702 to protrude and contact the film conveyed on the outer wall of the transmission roller 701, thereby cutting off the redundant parts on both sides of the film.

[0051] Due to the displacement of the fixed ring plate 608 that pushes the bevel rod 611 to displace, with the cooperation of the movable hinge 615 and the positioning hinge 606, the horizontal state between the bevel rod 611 and the rib plate 613 changes, and the outer arc plate 702 disengages from the state of overlapping with the rib plate 613. The knife plate 703 then moves away from the rib plate 613 and contacts the conveyed film, so that the edges of the film conveyed during the production of the sealing foam can be cut, improving the production efficiency of the sealing foam.

[0052] Example 3 further optimizes the sealing foam production process provided in Examples 1 and 2. Specifically, as Figure 3 、 Figure 5 、 Figure 7 and Figure 8 shown, the cleaning component 8 includes a number of transverse grooves 801 evenly distributed in a circumferential manner. A scraping plate 802 is movably connected to the inner wall of the transverse groove 801. A double air bag 803 is fixedly installed among several scraping plates 802. Both ends of the double air bag 803 are fixedly installed inside the transmission roller 701. When the two fixed ring plates 608 move towards the central shaft rod 607, they drive the positioning ring 805 connected by the extension rod 804 to move towards the piston plate 806, pushing the piston plate 806 to move towards the double air bag 803 in the auxiliary cylinder 807, so that the air in the auxiliary cylinder 807 enters the double air bag 803, causing the double air bag 803 to expand. The scraping plates 802 on the outer wall of the double air bag 803 are pushed out of the transverse grooves 801 on the outer wall of the transmission roller 701 and contact the conveyed film, scraping the surface of the film as the transmission roller 701 rotates to remove stains and grease on its surface.

[0053] The squeegee 802 is displaced by the inflated double airbag 803, causing the squeegee 802 to protrude from the transverse groove 801 on the outer wall of the transmission roller 701 and come into contact with the film conveyed on the surface of the transmission roller 701. As it rotates, the stains and grease on the film surface are cleaned. After the double airbag 803 contracts, the squeegee 802 moves downward, and the impurities on the side of the squeegee 802 cannot pass through the transverse groove 801 and are left on the surface of the transmission roller 701, thereby cleaning the squeegee 802. Thus, it is possible to scrape and clean the film conveyed during the production of the sealing foam, so that the stains and grease attached to the surface are cleaned, thereby improving the quality of the sealing foam production.

[0054] Further, as Figure 3 shown in Figure 5 , both ends of the transmission roller 701 are fixedly connected with auxiliary cylinders 807. The inner wall of the auxiliary cylinder 807 is movably connected with a piston plate 806. The piston plate 806 is movably installed on the outer wall of the central shaft rod 607. By moving the piston plate 806 in the auxiliary cylinder 807, the gas in the auxiliary cylinder 807 is pushed into the double airbag 803, causing it to expand.

[0055] Further, as Figure 3 shown in Figure 8 , a plurality of extension rods 804 are fixedly connected in a circumferentially uniform distribution at one end of the fixed ring plate 608 close to the central shaft rod 607. One end of several extension rods 804 on the same side is fixedly connected with a positioning ring 805. By driving the positioning ring 805 through the extension rods 804, the piston plate 806 in the auxiliary cylinder 807 is evenly pushed, so that the double airbag 803 expands evenly.

[0056] Further, as Figure 2 shown in Figure 6 , the other end of the positioning rod 601 is fixedly installed with a transmission shaft 11. The other end of the transmission shaft 11 penetrates through the pressing member 9 and is fixedly connected with a positioning gear 12. The power is transmitted through the positioning gear 12 to provide power for the rotation of the transmission roller 701.

[0057] Further, as Figure 1 shown in Figure 2 , a pressing roller 15 is provided at the lower end of the middle part of the pressing member 9. One end of the pressing roller 15 penetrates through the pressing member 9 and is fixedly connected with a transmission gear 13. An auxiliary gear 14 is engaged between the four positioning gears 12 and the transmission gear 13. The four positioning gears 12 and the transmission gear 13 are connected in series through the four auxiliary gears 14, so as to provide power for the rotation of the four transmission rollers 701 and the pressing roller 15.

[0058] Further, as Figure 1 shown in Figure 2As shown, a feeding component 2 is provided on one side above the bonding device 1, an upper shelf plate 3 is fixedly connected to the upper rear end of the bonding device 1, a feeding component 4 is provided in the middle above the upper shelf plate 3, and roller components 5 are provided on both sides of the feeding component 4. The feeding component 2 transports the foam, and the roller components 5 transport the foam.

[0059] Example 4, please refer to Figure 9 , a sealing foam is made using the sealing foam production process of Example 1 and Example 2.

[0060] The use process of the sealing foam and the production process thereof provided by the present invention is as follows:

[0061] Working principle: The staff places the foam on the roller component 5 for release, and the blue protective film is introduced by the feeding component 2, passes through the transmission component 10 for guided transmission, and the transmission gear 13 driven by the driving structure rotates, and the four positioning gears 12 are driven to rotate with the meshing transmission of the four auxiliary gears 14;

[0062] Cutting: Under the transmission of the positioning rod 601 and the transmission shaft 11, the threaded rod 602 at one end of the positioning rod 601 is driven. With the assistance of the central axis rod 607, the threaded rods 602 at both ends of the central axis rod 607 rotate synchronously, and the internal threaded tube 610 on the outer wall of the threaded rod 602 drives the fixed ring plate 608 to move, and the limiting groove 609 drives the bevel rod 611 to move toward the middle of the transmission roller 701. Due to the active space between the bevel rod 611 and the rib plate 613, the bevel rod 611 moves to the middle of the transmission roller 701. The movable hinge 615, and the other end of the rib plate 613 is connected by the positioning hinge 606. As the push is made, the angle between the bevel rod 611 and the rib plate 613 is gradually reduced, the horizontal state between the bevel rod 611 and the rib plate 613 changes, the outer arc plate 702 is separated from the state of overlapping with the rib plate 613, and the knife plate 703 connected by the outer arc plate 702 is driven to protrude and contact the film transported by the outer wall of the transmission roller 701, so as to cut the excess parts on both sides of the film;

[0063] Deviation correction and adjustment: Continue to push the bevel rod 611, and with the cooperation of the movable hinge 615, the rib plate 613 is turned upward with the positioning hinge 606, and the elastic cover 614 on the outer wall of the transmission roller 701 is stretched to expand in a trumpet shape, and the film on the top of the transmission roller 701 for material conveying is moved from both sides to the middle, so as to perform deviation correction and adjustment operations on the film;

[0064] Cleaning: As the fixed ring plate 608 continues to move with the internal thread cylinder 610, the two fixed ring plates 608 move relative to each other. Driven by the extension rod 804, the positioning ring 805 contacts the piston plate 806, pushing the piston plate 806 to move in the auxiliary cylinder 807 towards the double airbag 803. As a result, the air in the auxiliary cylinder 807 enters the double airbag 803, causing the double airbag 803 to expand. The scraper 802 on the outer wall of the double airbag 803 is pushed out of the transverse groove 801 on the outer wall of the transmission roller 701 and contacts the conveying middle film. As the transmission roller 701 rotates, it scrapes the surface of the film to remove stains and grease on its surface;

[0065] Transportation: After the positioning ring 805 pushes the piston plate 806 to move to the maximum position in the auxiliary cylinder 807, the internal thread cylinder 610 stops rotating on the outer wall of the threaded rod 602. The positioning rod 601 that rotates independently due to the bearing 604 also drives the positioning cylinder 603 to rotate accordingly, causing the entire transmission component 10 to rotate and perform a transportation operation on the film during the production process of the sealing foam;

[0066] Reset: After the transportation of the film is completed, the positioning rod 601 rotates in the reverse direction, driving the threaded rod 602 to rotate in the reverse direction. In cooperation with the internal thread cylinder 610, the two fixed ring plates 608 gradually move away from each other, driving the two groups of angled rods 611 to move accordingly. With the cooperation of the movable hinge 615 and the positioning hinge 606, the angle between the angled rod 611 and the rib plate 613 gradually becomes horizontal. Immediately, the knife plate 703 connected to the outer arc plate 702 fits against the rib plate 613 for storage, and the elastic cover 614 contracts as the rib plate 613 approaches the transmission roller 701. At the same time, for the auxiliary cylinders 807 at both ends of the transmission roller 701, as the positioning ring 805 contacted by the piston plate 806 gradually moves away, the inflated state of the double airbag 803 contracts.
