Description

Technical Field

[0001] The present invention relates to the technical field of aerogel edge wrapping, and specifically to an aerogel full-edge encapsulation process and equipment. Background Art

[0002] Aerogel is a thermal insulation material. Compared with traditional materials such as asbestos and fiberglass, it has a lower thermal conductivity and stronger flame retardant ability. Therefore, its application in the fields of battery thermal insulation and fire prevention is relatively prominent.

[0003] In the prior art, such as a patent for a flame retardant and thermal insulation aerogel blanket for power batteries and its encapsulation process in China, the silica aerogel is cut into sheet-like blanket pieces, and two PETs coated with glue are used to sandwich the blanket pieces to form an intermediate with a three-layer structure of the first PET layer - blanket piece layer - second PET layer. The intermediate is compressed and encapsulated through an encapsulation mold at a set temperature, and then cured and formed to obtain a flame retardant and thermal insulation aerogel blanket for power batteries. In this encapsulation structure of the aerogel, there will be overlapping PET layers at the four peripheral edges of the encapsulated aerogel product. This part plays a role in sealing and bearing pressure. However, in actual use, for this overlapping part, trimming such as cutting cannot be performed, resulting in its inapplicability to high-precision occasions.

[0004] The patent publication number of the above cited document is: CN116766726A. Summary of the Invention

[0009] Optionally, the hemming die includes an assembly plate slidably and embeddedly mounted on the top of the lower die. The bottom plane of the assembly plate is flush with the top plane of the silica gel frame, and the assembly plate can slide over to the top of the silica gel frame after film encapsulation. In the U-shaped state, the top of the assembly plate is covered by the lower encapsulation film.

When the wing plate rotates, the outer wall of the lowest part of the wing plate is at the same horizontal plane as the top of the silica gel frame.

[0012] Optionally, a third heating plate is installed inside the wing plate. An electromagnetic bearing is installed on the lower die, and a rotor is rotatably installed inside the electromagnetic bearing.

The bottom of the upper die is designed with a convex part, and the convex part extends the upper encapsulation film downward into a convex shape, and the bottom of the convex part is assembled and matched with the assembly groove.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 11 The present invention provides a technical solution: an aerogel full-edge packaging device, comprising:

[0039] The hot press 1 and the lower die 2 inside it. The lower die 2 has a lower encapsulation film 4 laid flat and conveyed on its top. An assembly groove 3 is opened on the top of the lower die 2 below the lower encapsulation film 4; a downward hot pressing die, which can press and embed the silica gel frame 5 into the assembly groove 3, and restrict and convert the lower encapsulation film 4 into a U-shaped state with the opening facing upwards, and the downward hot pressing die can perform film encapsulation on the opening of the U-shaped state; a hemming die, which can perform hemming and hot pressing on the lower encapsulation film 4 on both sides of the silica gel frame 5.

[0040] In the prior art, in the encapsulation method of the PET layer - aerogel - PET layer structure, there will be overlapping parts around the aerogel, which is inconvenient for customers to handle and affects subsequent precise operations. In the present invention, by designing the silica gel frame 5, the silica gel frame 5 can replace the overlapping parts, and at the same time, the originally longer overlapping parts can be shortened as much as possible. It can not only reduce the overlapping parts, but also improve the encapsulation strength between the PET layer and the aerogel. At the same time, the silica gel frame 5 can also enhance the strength and shape retention of the outer edge of the aerogel. Secondly, through the cooperation of the lower die 2, the assembly groove 3 and the downward hot pressing die, the silica gel frame 5 can be quickly and efficiently encapsulated, improving the encapsulation efficiency without manual calibration and fitting. Thirdly, by designing the hemming die, the redundant lower encapsulation film 4 in the U-shaped state can be hemmed and hot pressed and adhered, improving the sealing and encapsulation strength between the lower encapsulation film 4 and the silica gel frame 5.

[0041] The following provides two implementation schemes of the hemming die:

[0042] Embodiment 1:

[0043] The hemming die includes an assembly plate 8 slidably installed in an embedded manner on the top of the lower die 2. The bottom plane of the assembly plate 8 is flush with the top plane of the silica gel frame 5, and the assembly plate 8 can slide over to the top of the silica gel frame 5 after film encapsulation. In the U-shaped state, the top of the assembly plate 8 is covered by the lower encapsulation film 4. Please refer to Figures 2 to 5 , in this embodiment, the hemming and hot pressing are carried out by translation. Specifically, by setting the assembly plate 8, the lower encapsulation film 4 exceeding the top of the lower die 2 is pushed and adhered to the top of the silica gel frame 5 by the translation of the assembly plate 8. Before this, the top and bottom of the silica gel frame 5 have both been completed with film encapsulation. At this time, the two ends of the lower encapsulation film 4 are used to cover and adhere the film on the upper layer of the silica gel frame 5, and then the adhered part is hot pressed by a hot pressing device, thereby improving the overall encapsulation quality and strength.

[0044] Among them, through the pushing of the assembly plate 8, uninterrupted right-angle encapsulation can be formed on both sides of the top of the silica gel frame 5. Based on the U-shaped state of the lower encapsulation film 4, all four edges on both sides of the silica gel frame 5 can be continuously covered without a disconnection process. Please refer to Figure 11, which is a defect of the existing encapsulation method. The weak area at the edge of the silicone frame 5 is the encapsulation weakness. In the present invention, by providing the lower encapsulation film 4 in a U-shaped state, the weak area will be covered by the lower encapsulation film 4 during encapsulation. At the same time, the folded part of the lower encapsulation film 4 can form a fitting assembly with the upper PET layer by using a hemming die, supplemented by hot pressing or glue coating, so as to ensure the firmness of the hemmed part and improve the quality and strength of the overall encapsulation.

[0045] On the basis of Embodiment 1, a second heating plate 9 is fixedly installed inside the assembly plate 8. A chute 11 is opened at the top of the lower die 2. An electronic slider 12 is slidably installed inside the chute 11. The electronic slider 12 is fixedly connected to the assembly plate 8. The travel distance of the assembly plate 8 is greater than the wall thickness of the border of the silicone frame 5. Please refer to Figures 2 to 5 , in this embodiment, through the cooperation of the chute 11, the electronic slider 12 and the assembly plate 8, the translation of the assembly plate 8 can be more easily controlled. At the same time, by designing the second heating plate 9, after hemming, the two PET layers can be thermally pressed together. It should be noted that before hemming, the downward hot pressing die needs to be withdrawn to peel off the PET layer and the base paper.

[0046] Embodiment 2:

[0047] The hemming die includes a wing plate 13 rotatably installed on the top of the lower die 2. When the wing plate 13 is in a vertical state, the outer wall of the wing plate 13 cooperates with the inner wall of the assembly groove 3 to limit the lower encapsulation film 4 to a U-shaped state. When the wing plate 13 rotates, the outer wall of the lowest part of the wing plate 13 is at the same horizontal plane as the top of the silicone frame 5. Please refer to Figure 6 and Figure 7 , different from Embodiment 1, the hemming method adopted in this embodiment is a flipping method. When the lower encapsulation film 4 is in a U-shaped state with the opening facing up, the wing plate 13 serves as a fitting part for the U-shaped state of the lower encapsulation film 4. When the hot pressing encapsulation is completed, the wing plate 13 is transformed from a fitting part to a functional part. At this time, the wing plate 13 deflects, driving the part of the lower encapsulation film 4 extending beyond the top of the silicone frame 5 to rotate, so that the PET layer of the lower encapsulation film 4 can be hemmed and cover the top of the silicone frame 5, so that the PET layer can be adhesively encapsulated with the PET layer on the top of the hot-pressed silicone frame 5, and then the two can be fixed by hot pressing or glue coating.

[0048] On the basis of the second embodiment, a third heating plate 14 is installed inside the wing plate 13, an electromagnetic bearing is installed on the lower die 2, a rotor is rotatably installed inside the electromagnetic bearing, the wing plate 13 is fixedly installed on the outer wall of the rotor, and the part of the wing plate 13 exceeding the frame of the lower die 2 is greater than the frame thickness of the silica gel frame 5. In this embodiment, the rotation of the wing plate 13 is controlled through the cooperation of the electromagnetic bearing and the rotor, so as to accurately control the flipping angle of the wing plate 13. Secondly, the length of the wing plate 13 can ensure that the hot pressing range is sufficient to ensure the strength of the edge folding hot pressing. In this process, since the top of the silica gel frame 5 has been adhered to the single-layer PET layer during the initial hot pressing, and at this time, since the outer wall of the lowest part of the wing plate 13 and the top of the silica gel frame 5 are at the same horizontal plane, when the wing plate 13 is flipped to the horizontal state, the lower encapsulation film 4 has been pressed against this PET layer, thus completing the hot pressing with high quality without the need to set up a tooling.

[0049] In the first and second embodiments, both ends of the lower encapsulation film 4 are connected to a conveying device or a material pulling device with a tension structure to ensure that the lower encapsulation film 4 can be kept in a taut state during the downward displacement of the silica gel frame 5.

[0050] In a more preferred embodiment, a concave plate cavity is opened inside the lower die 2, and a concave first heating plate 7 is installed inside the plate cavity. The heating range of the first heating plate 7 covers the inner wall of the assembly groove 3. The lower die 2 on both sides of the opening of the first heating plate 7 is configured with an opening design, and the opening design provides a discharging path for the encapsulated silica gel frame 5.

[0051] In a more preferred embodiment, the downward hot pressing die includes an upper die 15. The upper die 15 is slidably installed up and down on the hot press 1. Two assembly rollers 17 are rotatably installed on the upper die 15 through bearing seats. The two assembly rollers 17 are symmetrically designed. An upper encapsulation film 16 is conveyed flatly between the two assembly rollers 17. The bottom of the upper die 15 is designed with a convex part. The convex part extends the upper encapsulation film 16 downward into a convex shape, and the bottom of the convex part is assembled and matched with the assembly groove 3. A fourth heating plate 18 is installed inside the upper die 15. Please refer to Figures 8 to 10 , in this embodiment, through the cooperation of the convex part of the upper die 15 and the upper encapsulation film 16, a part of the upper encapsulation film 16 can protrude downward. The PET layer of the protruding part of the upper encapsulation film 16 can follow the downward displacement of the upper die 15 to be adhered to the top of the silica gel frame 5, thus completing accurate hot pressing. In this process, the upper die 15 will also first displace the silica gel frame 5 loaded with the aerogel felt 6 downward to drive the lower encapsulation film 4 into a U-shaped state with the opening facing upward, and then complete the encapsulation structure and perform hot pressing and fixing. Similarly, both ends of the upper encapsulation film 16 are associated with a feeding and discharging device with a tension mechanism. <​​​, a hydraulic system is installed inside the hot press 1. Multiple guide columns are designed on the hot press 1. The upper die 15 is vertically and slidably installed on the outer walls of the multiple guide columns. The output end of the hydraulic system controls the downward movement and pressure application of the overall upper die 15.

[0053] With the cooperation of the above structures, the silica gel frame can be encapsulated quickly and efficiently, improving the encapsulation efficiency. Secondly, with the hemming die, the excess lower encapsulation film 4 in the C-shaped state can be hemmed and thermally pressed and bonded, enhancing the sealing and encapsulation strength between the lower encapsulation film 4 and the silica gel frame 5.

[0054] An aerogel full-edge encapsulation process further includes an aerogel felt 6 bonded inside the silica gel frame 5 to form a heat insulation body, and includes the following steps:

[0055] S1, use a manipulator or an electrical tooling fixture to place the heat insulation body on the top of the flatly conveyed lower encapsulation film 4. The PET layer of the lower encapsulation film 4 contacts the bottom of the heat insulation body, and ensure that the outer frame part of the heat insulation body is directly above the assembly groove 3;

[0056] S2, drive the downward hot pressing die to move downward. Through the heat insulation body, the lower encapsulation film 4 is restricted to a C-shaped state with the opening facing upward, so that the PET layer of the lower encapsulation film 4 is bonded to the bottom of the heat insulation body, and the downward hot pressing die makes the upper encapsulation film 16 bonded to the top of the heat insulation body;

[0057] S3, after hot press encapsulation, control the hemming die to fold and thermally press the part of the lower encapsulation film 4 that exceeds the heat insulation body towards the top of the heat insulation body to improve the encapsulation strength of the heat insulation body.

[0058] Specifically, in S2, it further includes:

[0059] V1, the upper die 15 restricts the upper encapsulation film 16 to a downward convex state, and makes the convex part of the upper encapsulation film 16 a flat surface to facilitate matching with the top of the heat insulation body;

[0060] V2, the hydraulic system controls the upper die 15 and the upper encapsulation film 16 thereon to move downward to complete the bonding and hot pressing process;

[0061] V3, hydraulic reset to separate the PET layer of the upper encapsulation film 16 from the base paper layer.

[0062] In this process, the automatic operation of the aerogel full-edge encapsulation equipment can be used for fast, efficient and accurate assembly and hot press encapsulation, which not only improves the encapsulation efficiency but also enhances the product quality.

[0063] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
