Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an adhesive tape structure. Background Art

[0002] During the production and processing of soft-pack batteries, double-sided tape needs to be affixed to the soft-pack batteries. Double-sided tape is generally affixed to the surface of the soft-pack batteries to facilitate the subsequent assembly of electronic devices, to adhere the soft-pack batteries to the housing or frame of the electronic device, or to facilitate the fixing of multiple soft-pack batteries together to assemble into a battery pack.

[0003] In the prior art, an automatic glue sticking machine is usually used to stick double-sided adhesive tape to the surface of soft-pack batteries. Due to the lack of an effective positioning structure, the traditional adhesive tape cannot accurately position the base film and the cover paper during the glue sticking process, which in turn causes the automatic glue sticking machine to be unable to quickly and accurately peel off the base film and the cover paper, resulting in low glue sticking efficiency and uneven quality. With the rapid development of automated glue sticking technology, the traditional adhesive tape structure has gradually been unable to meet the needs of modern industrial production for high-precision and high-efficiency glue sticking operations. Therefore, it is necessary to develop a new type of adhesive tape structure to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a tape structure, which enables an automatic glue sticking machine to accurately and quickly position and peel off the tape by setting a first tearing position, a positioning groove and a second tearing position, making the entire glue sticking process simple and easy, thereby improving the glue sticking efficiency and glue sticking quality.

[0005] A tape structure comprises a base film, a tape body and a covering paper, wherein the base film and the covering paper are respectively arranged on two opposite sides of the tape body, one end of the base film extends outward to form two first tearing hand positions, a positioning groove is provided between the two first tearing hand positions, and the end of the covering paper close to the first tearing hand position is provided with a second tearing hand position, and the second tearing hand position extends from the covering paper to the positioning groove.

[0006] In the above technical solution, the two first tearing positions extending outward from one end of the base film provide a convenient positioning structure for the automatic glue laminating machine, so that the base film can be peeled off quickly and accurately, thereby improving the efficiency and accuracy of glue laminating. At the same time, a positioning groove is provided between the two first tearing positions. When the base film is placed on the automatic glue laminating machine, the mechanism on the automatic glue laminating machine extends into the positioning groove accordingly, so that the base film is accurately and stably placed in the predetermined position. At the same time, the automatic glue laminating machine quickly peels off the base film through the two first tearing positions. A second tearing position is provided on the side of the covering paper close to the first tearing position. The second tearing position extends from the covering paper to the positioning groove, that is, the covering paper extends a certain distance. After the base film is peeled off, the automatic glue laminating machine fits the adhesive paper to the soft-pack battery cell. When the soft-pack battery cell needs to be connected to other components, the automatic glue laminating machine peels off the covering paper through the second tearing position, so that the covering paper is separated from the adhesive paper body, thereby realizing the bonding of the soft-pack battery cell with other components. The utility model provides a first tearing hand position, a positioning groove and a second tearing hand position, so that the automatic glue sticking machine can accurately and quickly position and peel off the adhesive paper, and the whole glue sticking process is simple and easy, thereby improving the glue sticking efficiency and glue sticking quality.

[0007] Furthermore, at least one first positioning notch is provided at one end of the covering paper away from the second tearing position, and the adhesive tape body is provided with a second positioning notch opposite to the first positioning notch.

[0008] In the above technical solution, after the base film is peeled off, the automatic gluing machine can position the adhesive tape through the first positioning notch and the second positioning notch, thereby confirming the direction of the adhesive tape and ensuring the precise positioning of the adhesive tape during the gluing process.

[0009] Furthermore, the size of the base film is larger than the size of the adhesive tape body, and the adhesive tape body is located on the inner side of the base film.

[0010] In the above technical solution, by setting the size of the bottom film larger than that of the tape body and placing the tape body on the inner side of the bottom film, it means that the tape body can be completely covered on all sides by the bottom film, which helps to prevent the tape body from being contaminated, scratched or otherwise damaged during storage and transportation.

[0011] Furthermore, the width of the adhesive tape body is adapted to the width of the covering paper.

[0012] In the above technical solution, the width of the covering paper matches the width of the adhesive tape body, ensuring that the covering paper can completely cover the sticky surface of the adhesive tape body before gluing, effectively preventing the adhesive tape from being contaminated or weakened in viscosity during storage and transportation.

[0013] Furthermore, the base film and the cover paper are made of polycarbonate.

[0014] In the above technical solution, polycarbonate is a very strong and durable material that can resist impact, scratches and abrasion. Therefore, as the material of the base film and the cover paper, polycarbonate can ensure that the adhesive tape is not easily damaged during storage, transportation and use, thus extending its service life.

[0015] Furthermore, a high temperature resistant layer is coated on the side of the base film and the cover paper facing away from the adhesive tape body.

[0016] In the above technical solution, the adhesive tape needs to be placed in a high temperature box for 24 hours before use to test its adhesion. The high temperature resistant layer can effectively prevent the base film and cover paper from deforming, melting or producing harmful substances in a high temperature environment, thereby ensuring the stability and safety of the adhesive tape in a high temperature working environment.

[0017] Furthermore, the high temperature resistant layer is acrylic resin glue.

[0018] In the above technical solution, the acrylic resin glue has excellent high temperature resistance and can maintain stable physical and chemical properties under high temperature environment, so that the base film and cover paper coated with acrylic resin glue can be used for a long time under high temperature conditions without damage.

[0019] Furthermore, the adhesive tape body is square.

[0020] In the above technical solution, the square design makes it easier to achieve standardized production of the tape body, while also improving the compatibility of the tape structure with different automatic gluing machines. The standardized size makes it easier for the tape body to adapt to various gluing needs.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The first tearing position and positioning groove are set on the bottom film. The automatic glue laminating machine can position the bottom film through the first tearing position during the gluing process. Some structures of the automatic glue laminating machine can be extended into the positioning groove to quickly and accurately place the bottom film on the automatic glue laminating machine. The automatic glue laminating machine can quickly tear off the bottom film through the first tearing position and positioning groove to expose the adhesive paper body for use, which improves the convenience and efficiency of operation.

[0023] 2. A second tearing position is set on the covering paper. After the automatic glue laminating machine tears off the bottom film and laminates the adhesive tape to the soft-pack battery cell, when the soft-pack battery cell needs to be connected with other components, the automatic glue laminating machine can position the covering paper through the second tearing position, thereby peeling off the adhesive tape body from the covering paper to expose the adhesive tape body for use, further improving the convenience of operation.

[0031] The adhesive tape structure of the utility model will be further described in detail below in conjunction with specific embodiments and drawings. The drawings provide preferred implementations of the utility model. However, the utility model can be implemented in many different forms and is not limited to the implementation described herein.

[0032] Please refer to Figure 1 and Figure 2 In a preferred embodiment, the adhesive tape structure of the present invention comprises a base film 1, an adhesive tape body 2 and a covering paper 3. The base film 1 and the covering paper 3 are respectively arranged on two opposite sides of the adhesive tape body 2. Two first tearing hand positions 101 are extended outward from one end of the base film 1. A positioning groove 102 is provided between the two first tearing hand positions 101. A second tearing hand position 301 is provided at one end of the covering paper 3 close to the first tearing hand position 101. The second tearing hand position 301 extends from the covering paper 3 to the positioning groove 102.

[0033] In practical applications, the two first tearing positions 101 extending outward from one end of the base film 1 provide convenient peeling points for the automatic glue laminating machine, so that the base film 1 can be peeled off quickly and accurately, improving the efficiency and accuracy of glue laminating. At the same time, a positioning groove 102 is provided between the two first tearing positions 101 to avoid interference between the base film 1 and the structure on the automatic glue laminating machine. When the base film 1 is placed on the automatic glue laminating machine, the mechanism on the automatic glue laminating machine extends into the positioning groove 102 accordingly, so that the base film 1 is accurately and stably placed at the predetermined position. At the same time, the automatic glue laminating machine positions the base film 1 through the two first tearing positions 101, so that the base film 1 can be peeled off quickly. A second tearing position 301 is provided on the side of the covering paper 3 close to the first tearing position 101, which provides convenience for subsequent tearing of the covering paper 3. The second tearing position 301 extends from the covering paper 3 to the positioning groove 102, that is, the covering paper 3 extends a distance, so that the covering paper 3 and the adhesive tape body 2 are clearly layered. When the bottom film 1 is peeled off, the automatic glue sticking machine sticks the adhesive tape to the soft-pack battery cell. When the soft-pack battery cell needs to be connected to other components, the automatic glue sticking machine positions the covering paper through the second tearing position 301, thereby peeling off the covering paper 3, so that the covering paper 3 is separated from the adhesive tape body 2, thereby achieving the bonding of the soft-pack battery cell with other components. The utility model provides the first tearing position 101, the positioning groove 102 and the second tearing position 301, so that the automatic glue sticking machine can accurately and quickly position and peel off the adhesive tape, and the entire gluing process is simple and easy, which improves the gluing efficiency and gluing quality.

[0034] Please refer to Figures 1 to 3 , at least one first positioning notch 302 is provided at one end of the cover paper 3 away from the second tearing position 301, and the adhesive paper body 2 is provided with a second positioning notch 201 opposite to the first positioning notch 302. After the base film 1 is peeled off, the automatic adhesive machine can position the adhesive paper through the first positioning notch 302 and the second positioning notch 201, thereby confirming the direction of the adhesive paper and ensuring the accurate positioning of the adhesive paper during the adhesive application process. In actual application, the second tearing position 301 corresponds to the direction of the battery cell pole.

[0035] Please refer to Figure 1 The size of the bottom film 1 is larger than that of the adhesive tape body 2, and the adhesive tape body 2 is located on the inner side of the bottom film 1. By setting the size of the bottom film 1 larger than that of the adhesive tape body 2 and arranging the adhesive tape body 2 on the inner side of the bottom film 1, it means that the adhesive tape body 2 can be completely covered by the bottom film 1 on all sides, which helps to prevent the adhesive tape body 2 from being contaminated, scratched or otherwise damaged during storage and transportation.

[0036] At the same time, the width of the adhesive tape body 2 is matched with the width of the covering paper 3. The width of the covering paper 3 matches the width of the adhesive tape body 2, ensuring that the covering paper 3 can completely cover the sticky surface of the adhesive tape body 2 before gluing, effectively preventing the adhesive tape from being contaminated or weakened in the storage and transportation process. The design of matching widths allows users to use without worrying about the misalignment or incomplete coverage between the covering paper 3 and the adhesive tape body 2, thereby improving the convenience and efficiency of operation. At the same time, the adhesive tape body 2 and the covering paper 3 with matching widths are more neat and beautiful in appearance, enhancing the visual effect of the product.

[0037] In this embodiment, the base film 1 and the cover paper 3 are made of polycarbonate. Polycarbonate is a very strong and durable material that can resist impact, scratches and wear. Therefore, as the material of the base film 1 and the cover paper 3, polycarbonate can ensure that the adhesive tape is not easily damaged during storage, transportation and use, and extend its service life. At the same time, polycarbonate has good transparency, which makes it easier for users to observe and locate the adhesive tape body 2 when the base film 1 and the cover paper 3 cover the adhesive tape body 2. In addition, polycarbonate is a recyclable material. Using polycarbonate as the material of the base film 1 and the cover paper 3 meets environmental protection requirements and helps reduce environmental pollution and waste of resources.

[0038] At the same time, the side of the base film 1 and the cover paper 3 facing away from the adhesive tape body 2 is coated with a high temperature resistant layer (not shown in the drawings). Before using the adhesive tape, it needs to be placed in a high temperature box for 24 hours to check the adhesion. The high temperature resistant layer can effectively prevent the base film 1 and the cover paper 3 from deforming, melting or producing harmful substances in a high temperature environment, thereby ensuring the stability and safety of the adhesive tape in a high temperature working environment. After the high temperature resistant layer is applied, the adhesive tape can adapt to more working environments, such as high temperature production lines, ovens, baking ovens, etc., thereby expanding the use range and application field of the adhesive tape.

[0039] In this embodiment, the high temperature resistant layer is acrylic resin glue. Acrylic resin glue has excellent high temperature resistance and can maintain stable physical and chemical properties under high temperature environment, so that the base film 1 and the cover paper 3 coated with acrylic resin glue can be used for a long time under high temperature conditions without damage.

[0040] Please refer to Figure 1 and Figure 2, the adhesive tape body 2 of this embodiment is square. The square design makes it easier to achieve standardized production of the adhesive tape body 2, and also improves the compatibility of the adhesive tape structure with different automatic adhesive laminating machines. The standardized size makes it easier for the adhesive tape body 2 to adapt to various adhesive laminating needs. The square adhesive tape body 2 is easier to stack and store, and also facilitates stability and safety during transportation. It should be noted that the shape of the adhesive tape body 2 is not limited to a square. When used, the adhesive tape body 2 of different shapes can be set according to the specific implementation scenario, and the shapes of the base film 1 and the cover paper 3 need to be consistent with the shape of the adhesive tape body 2.
