Description

Technical Field

[0001] The present application belongs to the technical field of battery packaging, and specifically relates to a diaphragm assembly and an assembly tool. Background Art

[0002] Due to its wear resistance, cold resistance, high strength, and light weight, the Mylar structure can protect the packaged objects to a certain extent. It is widely used in soft packaging in various industries such as food, batteries, and metal wires, and has a wide range of uses. Therefore, due to problems such as adaptability, irregularly shaped Mylar structures often have problems with tearing at the notch during manual attachment, resulting in low production efficiency and yield. At present, when manually attaching the Mylar structure, one solution is to avoid the problem of tearing at the notch by increasing working hours and labor costs, but this will lead to reduced production efficiency. Another solution is to reduce the viscosity of the glue between the Mylar structure and the release film to avoid tearing at the notch, but this solution will cause the Mylar structure to be loosely attached to the product, causing the Mylar structure to warp, resulting in a reduction in production yield.

[0028] Due to its wear resistance, cold resistance, high strength, and light weight, the Mylar structure can protect the packaged objects to a certain extent. It is widely used in soft packaging in various industries such as food, batteries, and metal wires, and has a wide range of uses. The Mylar structure is widely used. Therefore, due to problems such as adaptability, irregularly shaped Mylar structures often have problems with tearing at the notch during manual attachment, resulting in low production efficiency and production yield. At present, when manually attaching the Mylar structure, one solution is to avoid the problem of tearing at the notch by increasing working hours and labor costs, but this will lead to reduced production efficiency. Another solution is to reduce the viscosity of the glue between the Mylar structure and the release film to avoid tearing at the notch, but this solution will cause the Mylar structure to be loosely attached to the product, causing the Mylar structure to warp, resulting in a reduction in production yield.

[0029] In view of this, the present application provides a diaphragm assembly, including a release layer and a diaphragm layer. The release layer is provided with a plurality of first virtual knife lines, the plurality of first virtual knife lines are arranged at intervals along a first direction, the first virtual knife lines extend along a second direction and penetrate through both sides of the release layer, and the first direction intersects with the second direction. The diaphragm layer is connected to one side of the release layer, and the orthographic projection of the diaphragm layer on the release layer covers at least part of the plurality of first virtual knife lines. By setting a plurality of first virtual knife lines arranged at intervals along the first direction, it is possible to partially tear off the release layer and attach the activated diaphragm layer to the product. With such a configuration, stress can be reduced, tearing of the diaphragm layer can be avoided, and production efficiency and production yield can be improved.

[0034] In some embodiments, the release layer 1 includes a plurality of release portions 13 arranged and connected along a first direction X, a plurality of first virtual knife lines 10 divide the release layer 1 into a plurality of release portions 13 arranged and connected along the first direction X, and a first virtual knife line 10 is provided between two adjacent release portions 13.

By providing the second virtual knife line 11, the release portion 13 can be divided into a plurality of first release sub-portions 14, thereby further reducing stress, avoiding tearing of the membrane layer 2, and improving production yield.

[0035] In some embodiments, the release layer 1 is further provided with at least one third virtual knife line 12, the third virtual knife line 12 extends along the second direction Y and at least one side of the third virtual knife line 12 is connected to the second virtual knife line 11, and at least one third virtual knife line 12 divides the first release sub-portion 14 into a plurality of second release sub-portions 15 arranged and connected along the first direction X, and a third virtual knife line 12 is provided between two adjacent second release sub-portions 15. By providing the third virtual knife line 12, the first release sub-portion 14 can be further divided into a plurality of first release sub-portions 14, thereby further reducing stress, avoiding tearing of the membrane layer 2, and improving production yield.

[0036] In some embodiments, the release layer 1 is provided with a plurality of positioning holes 16, and the orthographic projection of the membrane layer 2 on the release layer 1 is located outside the positioning holes 16. The plurality of positioning holes 16 of the release layer 1 are arranged on the peripheral side of the membrane layer 2. The release layer 1 is fixed to the assembly tool through the positioning holes 16, so that the membrane layer 2 can be accurately positioned, ensuring that the position of the membrane layer 2 relative to the product is accurate and preventing displacement and misalignment.

In an embodiment of the present application, the adhesive layer can firmly adhere the diaphragm 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 release layer 1 during the separation process, thereby reducing stress while avoiding the problem of warping of the diaphragm layer 2 and low production yield caused by loose attachment.
