[0028] Die-cut parts are widely used in the housing, windows, batteries, connectors, circuit boards, backlight modules, camera modules, sound modules and other components of consumer electronic products, playing a role in structural or functional reinforcement and auxiliary. Die-cut parts usually include release films and materials. The release films and materials are separated to attach the materials to the corresponding positions. Current die-cut parts usually have three layers of release films. During the material attachment process, it is necessary to peel off one layer of release film, adjust the direction and position it through the positioning holes, and then peel off two layers of release film in turn to activate the material and attach it to the corresponding position. There are problems of complex procedures and low production efficiency.

[0029] In view of this, the present application provides a die-cutting part, comprising a first release film layer, a plurality of insulating layers and a plurality of second release film layers. The plurality of insulating layers are arranged on the first release film layer along a first direction and connected to the first release film layer. The insulating layer comprises a first sub-layer and a second sub-layer connected to each other, and the first sub-layer is connected to the first release film layer.

For the insulating layer with low appearance requirements, the setting of the release film layer between the insulating layer and the first release film layer can be cancelled, so that part of the insulating layer is connected to the first release film layer, and the other part is connected to the second release film layer. By reducing the redundant design of the die-cutting part, the assembly steps can be simplified and the assembly efficiency can be improved.

[0030] The die-cutting parts and assembly tools of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0031] Figure 1 is a top view of the first die-cut piece of the embodiment of the present application; Figure 2 is a top view of the second die-cut piece of the embodiment of the present application; Figure 3 is a schematic structural diagram of a second die-cut piece according to an embodiment of the present application; Figure 4 is a partial enlarged view of the second die-cut piece of the embodiment of the present application; Figure 5 It is a structural schematic diagram of a roll structure of another embodiment of the present application.

[0032] refer to Figures 1 to 5 The present application provides a die-cut part, comprising a first release film layer 1, a plurality of insulating layers 2 and a plurality of second release film layers 3. The plurality of insulating layers 2 are arranged on the first release film layer 1 along a first direction X and connected to the first release film layer 1. The insulating layer 2 is used to make the packaging, isolation and fixing parts of the battery to ensure the insulation performance of the battery while providing structural support and protection. The insulating layer 2 comprises a first sublayer 20 and a second sublayer 21 connected to each other, and the first sublayer 20 is connected to the first release film layer 1. The plurality of second release film layers 3 are arranged on the first release film layer 1 along a first direction X and connected to the first release film layer 1. The first direction X is the length direction of the first release film layer 1. The first release film layer 1 is used to neatly arrange the plurality of insulating layers 2 so as to improve the assembly efficiency. The second sublayer 21 is arranged on at least a portion of the second release film layer 3, and the second sublayer 21 is connected to a side of the second release film layer 3 away from the first release film layer 1. By separating the first release film layer 1 and the second release film layer 3, the insulating layer 2 can be activated and attached to the corresponding position of the battery. For the insulating layer 2 with low appearance requirements, the setting of the release film layer between the insulating layer 2 and the first release film layer 1 can be eliminated, so that the first sub-layer 20 is connected to the first release film layer 1, and the second sub-layer 21 is connected to the second release film layer 3. By reducing the redundant design of the die-cut parts, the assembly steps can be simplified and the assembly efficiency can be improved.

[0033] In some embodiments, the second release film layer 3 is provided with at least one positioning hole 30, and along the thickness direction of the second release film layer 3, the orthographic projection of the insulating layer 2 on the second release film layer 3 is located outside the positioning hole 30. The positioning hole 30 is arranged on the peripheral side of the insulating layer 2. In the embodiment of the present application, since the release force between the insulating layer 2 and the first release film layer 1 is greater than the release force between the first release film layer 1 and the second release film layer 3, the first release film layer 1 can be separated from the second release film layer 3 first, so that the second release film layer 3 and the insulating layer 2 connected to the second release film layer 3 can be fixed to the assembly jig through at least one positioning hole 30. After the positioning is completed, the first release film layer 1 connected to the insulating layer 2 can be separated to attach the activated first sublayer 20 to the corresponding position of the battery. Finally, the second release film layer 3 can be separated from the second sublayer 21 to attach the activated second sublayer 21 to the corresponding position of the battery. Such a setting can simplify the assembly steps and improve the assembly efficiency.

[0034] exist Figure 1 In the illustrated embodiment, the first sublayer 20 and the second sublayer 21 are arranged along the second direction Y, and the first direction X and the second direction Y intersect. In the embodiment of the present application, the second direction Y is the width direction of the first release film layer 1, and the first direction X and the second direction Y are perpendicular to each other. A plurality of second release film layers 3 are arranged along the first direction X and connected to each other, and a first virtual knife line 31 is provided between two adjacent second release film layers 3, and the two connected second release film layers 3 can be separated by the first virtual knife line 31.

[0035] In some embodiments, at least one positioning hole 30 located in the second release film layer 3 is arranged around the circumference of the insulating layer 2. Figure 1 In the illustrated embodiment, the positioning holes 30 on the second release film layer 3 are arranged on one side of the insulating layer 2 along the second direction Y. Specifically, there are two positioning holes 30, which are arranged at intervals along the first direction X and are located on one side of the insulating layer 2 along the second direction Y. The connected second release film layer 3 and the insulating layer 2 can be positioned by cooperating with the positioning parts on the assembly jig through the multiple positioning holes 30 to position the insulating layer 2.

[0036] exist Figure 2In the illustrated embodiment, the first sublayer 20 and the second sublayer 21 are arranged along the first direction X. A plurality of second release film layers 3 are arranged at intervals along the first direction X. With such an arrangement, there is no need to separate the second release film layer 3, which can further improve the assembly efficiency. The positioning hole 30 is arranged between two adjacent insulating layers 2. Specifically, there are two positioning holes 30, and the two positioning holes 30 are arranged at intervals along the second direction Y and are located on one side of the insulating layer 2 along the first direction X. The connected second release film layer 3 and the insulating layer 2 can be positioned by cooperating with the positioning portion on the assembly jig through the plurality of positioning holes 30 and the positioning portion on the assembly jig to position the insulating layer 2. With such an arrangement, the positioning holes 30 and the positioning portion on the assembly jig can cooperate to achieve precise positioning of the insulating layer 2. This ensures the accurate position of the insulating layer 2 during the assembly process to prevent displacement and misalignment.

[0037] In some embodiments, the insulating layer includes an adhesive layer (not shown), which is disposed on the first sublayer 20 and the second sublayer 21 facing the first release film layer 1. The adhesive layer is connected to the first release film layer 1 and the second release film layer 3, respectively. The adhesive layer is used to adhere the insulating layer 2 to the corresponding position of the battery. The adhesive layer can firmly adhere the insulating layer 2 to the corresponding position of the battery to prevent displacement. Selecting a suitable adhesive layer material and adjusting its viscosity characteristics can ensure that the release force provided by the adhesive layer matches the first release film layer 1 and the second release film layer 3 during the separation process.

[0038] In some embodiments, the material of the insulating layer 2 may be Nomex (polyisophthalamide), PI (polyimide), or other materials with insulating properties. Nomex and PI have good insulating properties, high temperature resistance, and corrosion resistance, and can withstand the high temperature, chemicals, and current generated during the use of the battery, provide safe insulation protection, and improve the safety and reliability of the battery.

The third direction Z is the thickness direction of the second release film layer 3. It is understood that the maximum dimension of the bending portion 22 along the thickness direction of the second release film layer 3 is greater than or equal to the maximum dimension of the second release film layer 3 in its thickness direction. The insulating layer 2 has high durability and tensile strength, and can adapt to a certain degree of deformation and irregular shapes. In the embodiment of the present application, by limiting the maximum dimension of the second release film layer 3 in its thickness direction, the impact on the overall aesthetics or quality of the insulating layer 2 can be reduced.

The plurality of first release film layers 1 are arranged along the first direction X, and a second virtual knife line 10 is provided between two adjacent first release film layers 1. The plurality of first release film layers 1 are connected to each other to prevent warping, and the second virtual knife line 10 is provided to facilitate separation of two adjacent first release film layers 1 for subsequent assembly. With such a configuration, continuous feeding can be achieved and assembly efficiency can be improved.
