Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, and in particular to a mold for facilitating the assembly of lithium-ion battery buttons. Background Technology

[0002] In the lithium-ion battery materials industry, lithium-ion battery material manufacturers or R&D fields typically assemble coin cells first, using cyclic voltammetry, AC impedance spectroscopy, and other tests to quickly measure the material's initial charge capacity, initial discharge capacity, initial efficiency, and other data to preliminarily determine whether the material's electrical performance meets technical requirements. This invention aims to design an assembly mold for lithium-ion coin cells, which greatly improves the assembly yield of coin cells and reduces the misalignment of the positive electrode, separator, and negative electrode caused by human factors, thereby enhancing the stability of coin cell testing. Therefore, the assembly mold is crucial in the coin cell assembly process.

[0003] Existing lithium-ion batteries suffer from the problem of misalignment of the positive electrode, separator, and negative electrode due to human error during manual assembly. Therefore, a mold is needed to facilitate the assembly of lithium-ion battery clips. Utility Model Content

[0004] The purpose of this invention is to provide a mold for assembling lithium-ion battery buttons, which solves the problem in the prior art where human factors cause misalignment of the positive electrode, separator, and negative electrode during manual assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for facilitating the assembly of lithium-ion battery buttons, comprising a main body, the top of the main body having several circular assembly slots, the middle of the assembly slots having a transverse through slot, and a label sticker affixed to the top of the main body.

[0006] Preferably, the assembly slots are provided at equal intervals in the horizontal direction about the top of the main body.

[0007] Preferably, the through groove is opened laterally through the middle of the assembly groove.

[0008] Preferably, when the abrasive is suitable for LIR2032, the dimensions of the main body are set to 18cm×8cm×3cm, the dimensions of the assembly groove are set to Φ2.1cm×0.15cm, and the dimensions of the through groove are set to 0.5cm×0.25cm.

[0009] Preferably, when the abrasive is suitable for LIR2025, the dimensions of the main body are set to 25cm×15cm×3cm, the dimensions of the assembly groove are set to Φ2.1cm×0.10cm, and the dimensions of the through groove are set to 0.5cm×0.25cm.

[0010] Preferably, the label is pasted below the assembly slot and corresponds to each assembly slot, and the label is marked with a number.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up assembly slots, several assembly slots are provided, allowing battery assembly operations to be performed in the middle of the assembly slots. This facilitates the alignment and assembly of smaller battery components, making assembly auxiliary operations easier. Furthermore, the through slots allow for the use of tweezers to grasp the coin cells in the middle during or after assembly, preventing situations where the batteries are difficult to remove. The overall design ensures accurate positioning and precision of the mold, avoiding issues caused by worktable movement and improving the coin cell assembly pass rate.

[0013] 2. By setting up labels, it is easy to make numerical markings after the labels are pasted, so as to facilitate the assembly comparison of batteries and avoid assembly confusion. This improves the accuracy and efficiency of assembly. The whole device is molded according to the dimensions of the drawings, and multiple sets of clasp batteries can be assembled at one time. Since each clasp battery has a fixed position, it will not cause confusion. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-3As shown in the figure, a mold for assembling lithium-ion battery buttons includes a main body 1. The top of the main body 1 has several circular assembly slots 2. A through slot 3 is horizontally opened in the middle of the assembly slots 2. A label sticker 4 is affixed to the top of the main body 1.

[0021] The assembly slot 2 has several slots that are equidistant from the top of the main body 1 in the horizontal direction, which allows for battery assembly operations to be performed in the middle of the assembly slot 2, making it convenient to align and assemble smaller battery components.

[0022] The through groove 3 is opened horizontally through the middle of the assembly groove 2. The through groove 3 can facilitate the clamping of the button battery in the middle with tweezers during or after assembly.

[0023] When the mold is suitable for LIR2032, the dimensions of the main body 1 are set to 18cm×8cm×3cm, the dimensions of the assembly slot 2 are set to Φ2.1cm×0.15cm, and the dimensions of the through slot 3 are set to 0.5cm×0.25cm. The appropriate dimensions and number of assembly slots 2 can be customized according to the batteries to be assembled. This data is one of the specifications.

[0024] When the mold is suitable for LIR2025, the dimensions of the main body 1 are set to 25cm×15cm×3cm, the dimensions of the assembly slot 2 are set to Φ2.1cm×0.10cm, and the dimensions of the through slot 3 are set to 0.5cm×0.25cm. The appropriate dimensions and number of assembly slots 2 can be customized according to the batteries to be assembled. This data is one of the specifications.

[0025] Label 4 is pasted below assembly slot 2 and corresponds to each assembly slot 2. Label 4 is marked with numbers. After the label 4 is pasted, it is easy to make numerical annotations so as to make the battery assembly comparison. This will not cause assembly confusion and improve the assembly accuracy and efficiency.

[0026] Working principle: First, the components of the coin cell are placed sequentially from bottom to top inside the assembly slot 2. The battery assembly operation can be carried out in the middle of the assembly slot 2. Multiple coin cells can be assembled at the same time. The corresponding assembly operation is carried out with the help of the label 4 to avoid confusion in the installation of parts. After the assembly is completed, the coin cells in the assembly slot 2 are further clamped by inserting tweezers into the through slot 3, and the coin cells in the middle can be clamped and removed.
