Description

TECHNICAL FIELD

[0001] The application relates to the technical field of thermal insulation material packaging, in particular to a roll-type packaging structure of aerogel double-sided adhesive. BACKGROUND

[0002] In recent years, with the rapid development of new energy vehicles and energy storage industries, the energy density and power density of lithium ion batteries continue to increase, and the thermal management problem of the battery cell during charging and discharging is increasingly prominent. Aerogel thermal insulation pads are widely used in thermal isolation protection between battery cells due to their excellent high-temperature resistance (can withstand more than 600 DEG C), ultra-low thermal conductivity (<0.02 W / m·K) and lightweight characteristics. The traditional aerogel adhesive product is mainly in the form of sheet material, as shown in FIG. 1, which needs to go through the processes of grabbing, tearing off the release paper 8, pasting, tearing off the release paper 8, and so on, so as to paste the aerogel thermal insulation pad 3 on the battery cell 7. Since the release paper needs to be torn twice during the whole process, the assembly efficiency is low, and in addition, this structure also has high requirements for the flatness of the hand tearing position of the release paper, otherwise the mechanical arm cannot effectively grab. Figures 4-5

[0003] To solve the above technical problems, a continuous release material bearing aerogel thermal insulation pad packaging structure is disclosed in the Chinese utility model patent with the application number CN202420104706.1, which realizes overall packaging by pasting multiple aerogel thermal insulation pads on a continuous release material layer, so as to realize the effect of automatic packaging. However, this scheme only sets a single release material layer, and in the production process, after the aerogel thermal insulation pad is pasted on the release material layer, a separate bearing film needs to be arranged on the outer surface of the aerogel thermal insulation pad to protect the adhesive surface, and in use, the bearing film also needs to be removed, which also causes the problems of heavy workload and low work efficiency. UTILITY MODEL CONTENT

[0004] In order to solve the problem of low assembly efficiency of the existing aerogel thermal insulation pad packaging structure in the above background technology, the application provides a roll-type packaging structure of aerogel double-sided adhesive.

[0005] The roll-type packaging structure of aerogel double-sided adhesive provided by the application adopts the following technical scheme:

[0006] A roll-type packaging structure of aerogel double-sided adhesive, comprising a first release layer and a second release layer wound parallel to each other, a plurality of aerogel thermal insulation pads are arranged between the two layers in a spaced manner, the upper and lower surfaces of each aerogel thermal insulation pad are respectively bonded to the first release layer and the second release layer through double-sided adhesive, and the first release layer, the second release layer and the aerogel thermal insulation pad arranged therebetween together form a stackable structure that can be wound and unwound.

[0007] ​By adopting the technical scheme, the double-layer release layer is used to replace the single bearing film matched with the outer surface of the aerogel thermal insulation pad in the process of manufacturing the packaging structure, which is beneficial to improve the manufacturing efficiency; and when the packaging structure is used, the first release layer or the second release layer is only needed to be opened, and the aerogel thermal insulation pad can be accurately positioned and pasted under the action of the automatic equipment, and the first release layer and the second release layer can be wound after use, which can be repeatedly used, and the problem of resource waste is reduced.

[0008] In addition, by adopting the technical scheme, the roll-shaped packaging structure is used to replace the traditional single release paper structure, which can replace the work process of frequently tearing the release paper, improve the assembly efficiency, and solve the problem that the mechanical arm cannot be effectively gripped due to the poor flatness of the release paper torn by hand.

[0009] Optionally, the first release layer and the second release layer are both release films.

[0011] By adopting the technical scheme, the release film made of PET material has high tensile strength (up to 200 Mpa or more) and puncture resistance, and is not prone to deformation or rupture during winding, which ensures the structural stability of the aerogel thermal insulation pad during high-speed winding and unwinding; and the PET material can provide stable peeling force, which can ensure that the double-sided adhesive does not accidentally separate during storage, and facilitate smooth peeling during automatic access; in addition, the material also has the advantages of high temperature resistance, uniform thickness, environmental protection and recycling, high surface flatness and low cost.

[0012] Optionally, the spacing between adjacent two aerogel thermal insulation pads is equal.

[0013] By adopting the technical scheme, it is mainly used for accurate synchronization with the automatic equipment during use, so that the mechanical hand can accurately grasp the aerogel thermal insulation pad at a fixed pace, thereby improving the efficiency of pasting.

[0014] Optionally, the outer edge of the double-sided adhesive does not exceed the outer contour boundary of the aerogel thermal insulation pad.

[0015] By adopting the technical scheme, it is used to avoid contact between adjacent double-sided adhesives during winding, and prevent the occurrence of adhesive accidents during unwinding.

[0016] Optionally, the first release layer, the second release layer and the aerogel thermal insulation pad together constitute a hollow center of the roll-shaped structure, and a winding core is installed at the hollow structure.

[0017] By adopting the technical scheme, the roll core can provide rigid support for the roll material, so that the core collapse of the product during transportation is avoided.

[0018] Optionally, the aerogel thermal insulation pad is provided with one or more columns along the length direction of the first release layer and the second release layer.

[0019] By adopting the technical scheme, different production occasions can be adapted, the efficiency of automatic production is improved, and the multiple columns of aerogel thermal insulation pads are also conducive to enhancing the overall structural strength of the packaging structure and reducing costs.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] The utility model discloses simple and reasonable design structure can make in the process of making the packaging structure, utilize double -layer release layer and spare aerogel thermal insulation pad outer surface collocation single bearing film, be favorable to improving the efficiency of making, and when using the packaging structure, only need to uncover first release layer or second release layer, can control aerogel thermal insulation pad and paste accurately under the action of automatic equipment, and first release layer and second release layer can be rolled up after use, can be repeatedly used, reduce the problem of resource waste.

[0030] The application will be further described in detail below with reference to the accompanying drawings.

[0031] As Figures 1-3 shown, the application discloses an aerogel double-sided adhesive tape roll packaging structure, which comprises a first release layer 1 and a second release layer 4 wound in parallel with each other. Both the first release layer 1 and the second release layer 4 are in a long strip structure and are release films. In this embodiment, the release film is made of PET material, which can have better tensile strength, puncture resistance and structural stability. It can be understood that the first release layer 1 and the second release layer 4 can also use release paper, PE film or OPP film, etc., which can also have a release effect.

[0032] A plurality of aerogel thermal insulation pads 3 are arranged between the two layers, i.e. the plurality of aerogel thermal insulation pads 3 are located between the first release layer 1 and the second release layer 4. In this embodiment, the plurality of aerogel thermal insulation pads 3 are distributed at equal intervals and arranged in one column. In other embodiments, the aerogel thermal insulation pads 3 between the two release layers can be arranged in two or more columns to meet different use occasions and improve production efficiency.

[0033] The upper and lower surfaces of each aerogel thermal insulation pad 3 are respectively bonded to the first release layer 1 and the second release layer 4 by the double-sided adhesive tape 2, so that the first release layer 1, the second release layer 4 and the aerogel thermal insulation pad 3 sandwiched therebetween together form a stackable structure that can be wound and unwound. Specifically, in operation, the release force between the first release layer 1 and the double-sided adhesive tape 2 is less than the release force between the second release layer 4 and the double-sided adhesive tape 2, so that the first release layer 1 can be peeled off alone. In this way, the second release layer 4 can be transported to a designated position with the aerogel thermal insulation pad 3, and the aerogel thermal insulation pad 3 can be adsorbed by the suction cup 6 and pasted on the surface of the battery cell 7.

[0034] Specifically, the outer edge of the double-sided adhesive tape 2 does not exceed the outer contour boundary of the aerogel thermal insulation pad 3, so as to prevent contact between adjacent double-sided adhesive tapes 2 during winding.

[0035] Specifically, the first release layer 1, the second release layer 4 and the aerogel thermal insulation pad 3 together form a hollow structure at the center of the roll, and a roll core 5 is installed at the hollow structure. In this embodiment, the roll core 5 can be made of steel or engineering plastic, etc., which can provide rigid support and facilitate quick installation of the roll product on a designated horizontal shaft to realize quick assembly during use.

[0036] When the aerogel double-sided adhesive tape roll packaging structure is used, as Figure 3As shown, the product is installed to the designated position through the winding core 5, and can be rotated with the axis parallel to the horizontal plane. During the work, one end of the product can be pulled outwards, and the first release layer 1 is peeled off from the product during the pulling process, and can be wound up separately to facilitate the reuse of the release layer, reduce material waste, save costs, and the second release layer 4 with the aerogel thermal insulation pad 3 is forwarded (a servo motor can be used to drive the forwarding speed to remain constant), and when forwarded to the designated position, the suction cup 6 can be in contact with the surface of the double-sided adhesive tape 2 to separate the aerogel thermal insulation pad 3 from the second release layer 4. The separated aerogel thermal insulation pad 3 can be attached to the surface of the electric core 7 at the designated position, thereby completing the automatic installation of the aerogel thermal insulation pad 3. After the second release layer 4 continues to be forwarded, it can also be wound up separately.

[0037] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
