TECHNICAL FIELD
[0001] The utility model relates to the field of electric core packaging, specifically, especially one kind is wrapped in rubber paper of three-in-one electric core. BACKGROUND
[0002] The electric core of battery needs to be wrapped and protected by electric core wrapping rubber paper after production, and the traditional electric core wrapping rubber paper is mostly wrapped separately in three parts, which are usually the head, middle and tail of the electric core. The head rubber paper is used to wrap the head of the electric core, i.e. one end with a circuit board, and the middle rubber paper and the tail rubber paper are used to wrap the main body and the tail of the electric core. However, the traditional electric core wrapping rubber paper is independent of three parts, so it needs to be wrapped and pasted separately on three parts of the electric core, which will result in low wrapping efficiency and is not conducive to mass production of electric core products. SUMMARY
[0003] Therefore, the utility model provides a three-in-one electric core wrapping rubber paper which can complete the wrapping of the electric core with one-time pasting.
[0004] The utility model discloses a three-in-one electric core wrapping rubber paper.
[0005] The utility model discloses a three-in-one electric core wrapping rubber paper, which comprises a head rubber paper, a middle rubber paper and a tail rubber paper connected in sequence, left and right side rubber papers connected to the opposite sides of the middle rubber paper, a pulling part and two pasting parts of the right side rubber paper, the two pasting parts being symmetrically arranged on the opposite sides of the pulling part and being separable from the pulling part, the pulling part extending into the middle rubber paper, and a slot hole being arranged at one end of the pulling part extending into the middle rubber paper, wherein the pulling part is provided with a first strong glue area, the pasting part is provided with a second strong glue area, the left side rubber paper is provided with a third strong glue area, and glue overflow spaces are arranged between the side edge of the first strong glue area and the slot hole, between the side edge of the second strong glue area and the outer edge of the pasting part, and between the third strong glue area and the outer edge of the left side rubber paper.
[0006] In the above technical solution, the head rubber paper, the middle rubber paper and the tail rubber paper are connected in sequence, and the left and right side rubber papers are connected to the opposite sides of the middle rubber paper, forming a complete wrapping structure. When wrapping the electric core with rubber paper, the wrapping of the head, middle and tail of the electric core can be completed with one-time pasting, greatly improving the wrapping efficiency of the electric core.
[0007] The pulling part and the sticking part on the right side of the adhesive paper can be separated from each other, so that the pulling part can be separated from the sticking part after the sticking is completed, and the battery cell can be separated from the device by pulling the pulling part, thereby facilitating the disassembly of the battery cell. In addition, the first strong glue area, the second strong glue area and the third strong glue area on the wrapping adhesive paper ensure the firm adhesion between the adhesive paper and the battery cell, thereby improving the reliability of the battery cell wrapping and effectively preventing the adhesive paper from falling off due to factors such as vibration and temperature change during long-term use. The overflow glue spacing between the edge of the strong glue area and the outer edge of the adhesive paper or the slot hole not only avoids the appearance defects caused by overflow of glue during glue pressing, but also reduces the pollution of the glue to the environment around the battery cell, and ensures the flatness and aesthetics of the adhesive paper during sticking.
[0008] Optionally, in a possible implementation, the pulling part and the two sticking parts are connected with the middle adhesive paper, and the connection between the two sticking parts and the pulling part is provided with a tearing line.
[0009] In the above technical solution, the pulling part and the two sticking parts are connected on the right side of the middle adhesive paper, and the setting of the tearing line greatly simplifies the operation process of separating the pulling part and the sticking part by the user. The user only needs to gently tear along the tearing line, and the pulling part and the sticking part can be easily separated without using additional tools or force, thereby improving the convenience and efficiency of the operation.
[0010] Optionally, in a possible implementation, the pulling part is further provided with a first glue-free area, and the first glue-free area is located on the side of the first strong glue area away from the slot hole.
[0011] In the above technical solution, the setting of the first glue-free area can effectively avoid the complete adhesion of the pulling part to the battery cell, which makes it difficult to separate the pulling part from the sticking part. That is, the existence of the first glue-free area makes the pulling part more easy to hold and operate. When the user needs to pull apart the pulling part, the fingers can easily be placed on the first glue-free area without worrying about the sliding or discomfort caused by the adhesion of the glue, thereby improving the comfort and convenience of the user operation.
[0012] Optionally, in a possible implementation, the middle adhesive paper is provided with a first weak glue area, and the first weak glue area covers the entire surface of the middle adhesive paper.
[0013] In the above technical solution, the middle adhesive paper serves as the main sticking part of the battery cell, and the design of the first weak glue area makes the middle adhesive paper have higher flexibility during sticking. Since the adhesion of the weak glue area is relatively weak, the user can more easily adjust the position of the battery cell or the wrapping adhesive paper without worrying about the difficulty of moving or damage caused by the glue being too strong.
[0014] Optionally, in a possible implementation, the adhesive part is further provided with a second weak glue area and a second glue-free area, and the second weak glue area, the second strong glue area and the second glue-free area are sequentially arranged in a direction away from the middle glue paper.
[0015] In the above technical solution, the ingenious design of the second weak glue area and the second glue-free area reduces unnecessary glue usage while maintaining the necessary adhesion, thereby reducing production costs. And the adhesive part can be easily separated from the pulling part by pulling the second glue-free area to peel off the adhesive part.
[0016] Optionally, in a possible implementation, the first strong glue area extends to the middle position of the second weak glue area away from one side of the slot hole.
[0017] In the above technical solution, by extending the first strong glue area to the middle position of the second weak glue area, the purpose is to realize the strong and weak bonding effect of the glue paper during pasting, to ensure the pasting strength while reducing the amount of glue used. During pasting, the second weak glue area can be pasted on the side of the battery cell, while part of the first strong glue area can also be pasted on the side of the battery cell at the same time, which can effectively improve the pasting strength of the glue paper.
[0018] Optionally, in a possible implementation, the left side glue paper is further provided with two third weak glue areas, both of which are connected with the middle glue paper, and the two third weak glue areas are separated by the third strong glue area.
[0019] In the above technical solution, the two third weak glue areas cooperate with the third strong glue area to help form a more reasonable stress distribution on the pasting surface, improving the overall stability and durability, while also ensuring that the glue paper has high pasting strength while reducing the amount of glue used.
[0020] Optionally, in a possible implementation, the left side glue paper is provided with a notch away from one side of the middle glue paper, and the notch is located between the two third weak glue areas.
[0021] In the above technical solution, the design of the notch provides a more intuitive and convenient indication for the pasting operation. The user can quickly identify and locate the area between the two third weak glue areas through the notch, thereby more accurately controlling the pasting position and strength. And the notch not only serves as a visual marker, but also as a reference point for positioning the pasting object.
[0022] Optionally, in a possible implementation, the glue overflow distance is 0.5-1mm.
[0023] In the above technical solution, controlling the glue overflow gap within the range of 0.5mm-1mm can effectively avoid inconsistent bonding results caused by excessive glue overflow. By precisely controlling the glue overflow gap, glue waste during the bonding process can be significantly reduced. Attached Figure Description

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] Please refer to Figure 1This embodiment provides a three-in-one battery cell wrapping adhesive tape, including: a head adhesive tape 1, a middle adhesive tape 2, and a tail adhesive tape 3 connected in sequence. The middle adhesive tape 2 is connected to a left adhesive tape 4 and a right adhesive tape 5 on opposite sides. The right adhesive tape 5 includes a pull-out part 51 and two adhesive parts 52. The two adhesive parts 52 are symmetrically arranged on opposite sides of the pull-out part 51 and can be separated from the pull-out part 51. The pull-out part 51 extends into the interior of the middle adhesive tape 2, and a slot 511 is provided at one end of the pull-out part 51 extending into the interior of the middle adhesive tape 2. The pull-out part 51 is provided with a first strong adhesive area 512, the adhesive part 52 is provided with a second strong adhesive area 522, and the left adhesive tape 4 is provided with a third strong adhesive area 41. An overflow gap 6 is provided between one side edge of the first strong adhesive area 512 and the slot 511, between one side edge of the second strong adhesive area 522 and the outer edge of the adhesive part 52, and between the third strong adhesive area 41 and the outer edge of the left adhesive tape 4. Among them, slot 511 is a strip-shaped through hole.
[0030] Specifically, the end of the battery cell with the tabs is designated as the head, the two largest opposing surfaces of the battery cell are the bottom and top surfaces, the side with the tabs is the top surface, the opposite side is the bottom surface, and the other two opposing surfaces are the left and right surfaces. In this embodiment, when applying the adhesive tape, the middle adhesive tape 2 is applied to the bottom surface of the battery cell, the head adhesive tape 1 is applied to and wraps around the circuit board and ribbon cables located on the top surface of the battery cell, and is partially applied to the top surface of the battery cell, the tail adhesive tape 3 is applied to the tail of the battery cell, and is also applied to the bottom, bottom, and top surfaces of the battery cell, the left adhesive tape 4 is applied to the left side of the battery cell, and is partially applied to the top surface of the battery cell, and the right adhesive tape 5 is applied to the right side of the battery cell, and is also applied to the bottom, bottom, and top surfaces of the battery cell.
[0031] In this embodiment, a complete wrapping structure is formed by sequentially connecting the head adhesive tape 1, the middle adhesive tape 2, and the tail adhesive tape 3, as well as the left adhesive tape 4 and the right adhesive tape 5 connected on both sides of the middle adhesive tape 2. When wrapping the battery cell with adhesive tape, the head, middle and tail positions of the battery cell can be wrapped with only one adhesive tape, which greatly improves the wrapping efficiency of the battery cell.
[0032] The pull-out portion 51 and the adhesive portion 52 on the right-side adhesive tape 5 are separable, allowing the pull-out portion 51 to detach from the adhesive portion 52 after adhesive application. Pulling the pull-out portion 51 then detaches the battery cell from the device, facilitating cell removal. Furthermore, the presence of a first strong adhesive area 512, a second strong adhesive area 522, and a third strong adhesive area 41 on the adhesive tape ensures a strong bond between the tape and the battery cell. This not only improves the reliability of the battery cell wrapping but also effectively prevents the tape from detaching due to vibration, temperature changes, or other factors during long-term use. The excess adhesive gap 6 between the edge of the strong adhesive area and the outer edge of the tape or the slot 511 not only prevents glue overflow during pressing, thus avoiding cosmetic defects, but also reduces glue contamination of the surrounding environment and ensures the flatness and aesthetics of the tape during application.
[0033] In this embodiment, the pull-out portion 51 and the two adhesive portions 52 are both connected to the middle adhesive tape 2, and tear lines 7 are provided at the connection points between the two adhesive portions 52 and the pull-out portion 51. Specifically, the pull-out portion 51 and the two adhesive portions 52 are arranged along the direction from the top adhesive tape to the tail adhesive tape 3.
[0034] The pull-out section 51 and the two adhesive sections 52 are both connected to the right side of the middle adhesive tape 2. The tear line 7 greatly simplifies the process of separating the pull-out section 51 and the adhesive sections 52. The user can easily separate the pull-out section 51 from the adhesive section 52 by simply tearing along the tear line 7 without using additional tools or force, thus improving the convenience and efficiency of the operation.
[0035] In this embodiment, the pull-out portion 51 is further provided with a first adhesive-free area 513, which is located on the side of the first strong adhesive area 512 away from the slot 511. The provision of the first adhesive-free area 513 can effectively prevent the pull-out portion 51 from being completely adhered to the battery cell, which would make it difficult for the pull-out portion 51 to detach from the adhesive portion 52. That is, the presence of the first adhesive-free area 513 makes the pull-out portion 51 easier to hold and operate. When the user needs to pull out the pull-out portion 51, their fingers can be easily placed on the first adhesive-free area 513 without worrying about slippage or discomfort caused by glue adhesion, thus improving the user's operating comfort and convenience.
[0036] In this embodiment, the intermediate adhesive tape 2 has a first weak adhesive area 21, which covers the entire surface of the intermediate adhesive tape 2. The intermediate adhesive tape 2 serves as the main bonding part 52 of the battery cell, and the design of the first weak adhesive area 21 provides greater flexibility during bonding. Because the adhesive strength of the weak adhesive area is relatively weak, users can more easily adjust the position of the battery cell or the wrapping tape without worrying about difficulty in movement or damage due to excessive adhesive strength.
[0037] In this embodiment, the adhesive part 52 is further provided with a second weak adhesive area 521 and a second no adhesive area 523. The second weak adhesive area 521, the second strong adhesive area 522, and the second no adhesive area 523 are arranged sequentially in a direction away from the middle adhesive paper 2. Specifically, the second weak adhesive area 521 is adhered to the right side of the battery cell, and the second strong adhesive area 522 is adhered to the top surface of the battery cell.
[0038] The ingenious design of the second weak adhesive area 521 and the second adhesive-free area 523 allows the entire adhesive part 52 to maintain the necessary adhesion while reducing unnecessary glue usage, thereby lowering production costs. Furthermore, the adhesive part 52 can be peeled off by pulling the second adhesive-free area 523, making separation between the adhesive part 52 and the pull-out part 51 easier.
[0039] It should be noted that in this embodiment, the first strong adhesive area 512 extends from the side away from the slot 511 to the middle of the second weak adhesive area 521. By extending the first strong adhesive area 512 to the middle of the second weak adhesive area 521, the purpose is to achieve a strong-weak bonding effect of the adhesive tape during bonding, so as to ensure bonding strength while reducing the amount of adhesive used. During bonding, the second weak adhesive area 521 can be bonded to the side of the battery cell, while at the same time, part of the first strong adhesive area 512 can also be bonded to the side of the battery cell, thus effectively improving the bonding strength of the adhesive tape.
[0040] Specifically, when applying the adhesive tape 5 on the right side, part of the first strong adhesive area 512 is applied to the bottom surface of the battery cell. In conjunction with the first weak adhesive area 21, the adhesive tape can be stably applied to the bottom surface of the battery cell. In addition, part of the first strong adhesive area 512 is also applied to the right side of the battery cell. In conjunction with the two second weak adhesive areas 521, the adhesive tape can be stably applied to the right side of the battery cell. That is, a combination of strong adhesive and weak adhesive is used for application.
[0041] In this embodiment, the left-side adhesive tape 4 also has two third weak adhesive areas 42, both of which are connected to the middle adhesive tape 2, and are separated by a third strong adhesive area 41. Specifically, when pasting the left-side adhesive tape 4, part of the third strong adhesive area 41 is pasted on the left side of the battery cell, and the two third weak adhesive areas 42 are simultaneously pasted on the left side of the battery cell. This combination of strong and weak adhesive is used, which can ensure the stability of the pasting while saving adhesive material.
[0042] The two third weak adhesive zones 42 and the third strong adhesive zone 41 work together to help form a more reasonable stress distribution on the bonding surface, improving the overall stability and durability. At the same time, it ensures that the adhesive tape has high bonding strength while reducing the amount of adhesive used.
[0043] In this embodiment, a notch 43 is provided on the side of the left adhesive tape 4 away from the middle adhesive tape 2, and the notch 43 is located between the two third weak adhesive areas 42. The design of the notch 43 provides a more intuitive and convenient indication for the pasting operation. Users can quickly identify and locate the area between the two third weak adhesive areas 42 through the notch 43, thereby more accurately controlling the pasting position and pressure. Furthermore, the notch 43 can not only serve as a visual marker, but also as a reference point for positioning the adhesive.
[0044] It should be noted that the glue overflow spacing 6 in this embodiment is 0.5mm-1mm. Controlling the glue overflow spacing 6 within the range of 0.5mm-1mm can effectively avoid inconsistent bonding results caused by excessive glue overflow. By precisely controlling the glue overflow spacing 6, glue waste during the bonding process can be significantly reduced.
