Description

Technical Field

[0001] The utility model relates to an easy-to-tear and stick structure. Background Art

[0002] In the field of lithium battery use, in order to facilitate the disassembly of the battery from the whole machine, we often use the difference in the stickiness of strong and weak glue to divide the easy-to-tear sticker into a weak glue area and a strong glue handle area. When disassembling the battery, pull the strong glue handle area to separate the semi-finished battery from the weak glue area (the weak glue area is fixed to the cabin clock with strong sticky double-sided tape), so as to achieve the purpose of battery detachability. In the industry, the strong glue handle area and the weak glue area are often connected by virtual tangents, or divided into two independent parts. The virtual tangent connection design makes it easy for the easy-to-tear sticker to tear along the connecting point in the direction perpendicular to the virtual tangent when disassembling, and the strong glue handle area and the weak glue area are difficult to separate; the strong glue handle area and the weak glue area are designed as independent parts. When processing the PACK, it is impossible to use one device to complete the PACK processing of the easy-to-tear sticker at one time. In order to avoid the defects of the above two designs, the strong glue handle area and the weak glue area are connected by double virtual tangents into an easy-to-separate semi-integral, which can meet the one-time processing and can be separated smoothly.

[0003] In the design of the easy-tear sticker, the difference in viscosity between strong and weak glue is utilized (the strong glue double-sided tape bonds the battery (the weak glue area of ​​the easy-tear sticker) to the entire aircraft cabin, while the strong glue handle area is not bonded by the strong glue double-sided tape). When the strong glue handle area is pulled, the strong glue handle area is separated from the weak glue area, and the battery cell is simultaneously separated from the weak glue area of ​​the easy-tear sticker, and the strong glue handle area and the battery cell are lifted together, thereby achieving the purpose of detachability.

[0004] See also Figure 1 In the prior art 1, the strong glue handle area 2 and the weak glue area 1 of the easy-tear sticker are connected by the virtual tangent line 3, and the cutting position 31 and the material connection point position 32 coincide with each other. When disassembling, the easy-tear sticker is easily torn along the material connection point position 32 in the direction perpendicular to the virtual tangent line to form a tear line 33, and the strong glue handle area and the weak glue area are difficult to separate, or the weak glue area may be torn horizontally, causing the strong glue handle area to be damaged, resulting in disassembly failure;

[0005] See also Figure 2 In the prior art 2, the strong glue handle area 2 and the weak glue area 1 are designed as independent parts. During the PACK processing, it is impossible to use one device to complete the PACK processing of easy-to-tear stickers at one time. It is necessary to divide the two materials into two separate PACK processes, and the process actions are repeated. Utility Model Content

[0006] The purpose of the utility model is to solve the technical problems in the above background, and to propose an easy-tear sticker structure, which can connect the strong and weak glue areas into an easily separable semi-integral by using double virtual tangent lines, so as to meet the requirements of one-time processing and smooth separation, optimize the difficulty of separation of the strong and weak glue areas of the easy-tear sticker, and simplify the processing steps of the easy-tear sticker.

[0007] In order to achieve the above-mentioned purpose, the utility model provides an easy-to-tear structure, comprising a weak glue area and a strong glue handle area, wherein there is an interval space between the strong glue handle area and the weak glue area, one end of the strong glue handle area is connected to the weak glue area through a virtual tangent line, and the virtual tangent line has a cutting position and a connecting point position set at intervals, the connecting point position is used to connect the strong glue handle area with the weak glue area, and the cutting position is used to be able to tear along the cutting position during the tearing process.

[0008] Furthermore, the outer surface of the strong glue handle area includes a first end, a second end, a first side and a second side, the first end and the second end are arranged opposite to each other, the first side and the second side are arranged opposite to each other, the first end is located between the first side and the second side, and the first end is connected to the weak glue area through the virtual tangent line.

[0009] Furthermore, the spacing space is the second end portion, the first side portion, and the space between the second side portion and the weak adhesive area.

[0010] Furthermore, the weak glue area and the strong glue handle area have a whole piece of strong glue and dot-shaped weak glue, the whole piece of strong glue is arranged on the inner periphery of the weak glue area, and the connecting part between the strong glue handle area and the weak glue area, and the dot-shaped weak glue is arranged in the area other than the whole piece of strong glue.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The easy-tear structure of the utility model, on the one hand, will not produce tear lines in the strong glue handle area under the action of any force; on the other hand, the weak glue area and the strong glue handle area can be processed at one time without separate processing. This solves the technical problem that the strong glue handle area is easy to cause tear lines under the action of force or the weak glue area and the strong glue handle area need to be processed separately.

The whole piece of strong glue is arranged on the inner periphery of the weak glue area and the connecting part between the strong glue handle area and the weak glue area. The dot-shaped weak glue is arranged in an area other than the whole piece of strong glue.

[0026] The assembly steps of the easy-tear sticker structure of the utility model are as follows: the strong adhesive handle area and the weak adhesive area of ​​the easy-tear sticker are connected only on one side through double virtual tangent lines, and the other three sides are not connected in space, the easy-tear sticker is marked along the direction of the non-strong adhesive handle area, and after being positioned on the battery, the easy-tear sticker is reversely wrapped, and finally the strong adhesive double-sided tape is PACKed;
