Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm stratification, in particular to a high-efficiency stratification device. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The lithium battery diaphragm layering equipment is a special equipment used to layer a single-layer diaphragm into multiple layers. The layered multi-layer diaphragm will enter the winding mechanism and be rolled into a roll for subsequent battery manufacturing.

[0003] However, the existing stratification equipment usually operates in a one-to-two or one-to-four mode, which greatly reduces the efficiency during the stratification process. In addition, in the production process, it is difficult to reduce the cost by increasing the number of equipment to improve production efficiency. In view of this, we propose a high-efficiency stratification equipment. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] The utility model adopts the symmetrical arrangement of two groups of stratification components, so that the lithium battery diaphragm enters the stratification component after being initially stratified by the first film-breaking roller, and the lithium battery diaphragm is stratified twice and three times by the second film-breaking roller and the third film-breaking roller. At the same time, under the driving action of the gear drive box, the lithium battery diaphragm is stratified into eight layers, so there is no need to purchase additional stratification equipment, so as to achieve the purpose of improving stratification efficiency and reducing costs.

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1-2As shown, the utility model proposes a high-efficiency stratification device, including a support vertical plate 1 and a lithium battery diaphragm 3, the two support vertical plates 1 are symmetrically arranged, and the gear drive box 7 is fixedly installed on the back wall of one support vertical plate 1, which is used to provide power for the rotation of the rotating component to facilitate the subsequent stratification work; a plurality of bearing seats are installed on the opposite wall of the other support vertical plate 1, and the rotating ends of the plurality of bearing seats are respectively connected to the ends of the plurality of rotating components, so as to assist the rotating components to rotate during the stratification process; the first winding roller 2 is arranged between the opposite surfaces of the two support vertical plates 1, and the lithium battery diaphragm 3 is wound on the first winding roller 2, and the lithium battery diaphragm 3 is stored by the first winding roller 2; the two first film breaking rollers 4 are located at the first winding roller 2 At the top, and symmetrically arranged with the vertex of the supporting vertical plate 1 as the mirror point, the lithium battery diaphragm 3 is located between the two first film-breaking rollers 4, so that the symmetrical arrangement of the two groups of first film-breaking rollers 4 is convenient for the preliminary stratification of the lithium battery diaphragm 3, and because the position between the two groups of first film-breaking rollers 4 is staggered with the discharge position of the first winding roller 2, it is beneficial to tension the lithium battery diaphragm 3 in a stratified state to avoid affecting the stratification work; multiple first tensioning rollers 5 are evenly layered into two groups, and the two groups of first tensioning rollers 5 are in a staggered arrangement state, and are all in contact with the outer surface wall of the lithium battery diaphragm 3, so as to tension the stratified lithium battery diaphragm 3 and prevent the stratified lithium battery diaphragm 3 from loosening during the transmission process, resulting in subsequent winding wrinkles.

[0019] Furthermore, stratification components 6 are symmetrically installed on both sides of the first winding roller 2 for facilitating re-stratification of the stratified lithium battery diaphragm 3. The stratification component 6 includes a second film-breaking roller 61. The two second film-breaking rollers 61 are symmetrically arranged. The stratified lithium battery diaphragm 3 is located between the two second film-breaking rollers 61. The stratified lithium battery diaphragm 3 is subjected to secondary stratification by the second film-breaking rollers 61. The two second tensioning rollers 62 are symmetrically arranged between the opposite surfaces of the two supporting vertical plates 1, and are used to prop up and tension the lithium battery diaphragm 3 after the secondary layer to avoid relaxation of the lithium battery diaphragm 3 after the secondary stratification, which affects the subsequent winding work. The plurality of third film-breaking rollers 63 are evenly layered into two groups, and the two groups of third film-breaking rollers 63 are symmetrically arranged. The two third film-breaking rollers 63 of each group are also symmetrically arranged. The lithium battery diaphragm 3 after the second stratification is located between the two third film-breaking rollers 63 of each group. The third film-breaking roller 63 is used to realize the third stratification of the lithium battery diaphragm 3 after the second stratification, thereby improving the stratification efficiency and reducing the procurement cost without the need to purchase additional stratification equipment; multiple third tensioning rollers 64 are symmetrically arranged on one side of the third film-breaking roller 63, and are staggered with each third film-breaking roller 63, which is conducive to tensioning the lithium battery diaphragm 3 after the third stratification, and convenient for winding up the lithium battery diaphragm 3 after the third stratification; multiple second winding rollers 65 are all arranged between the two supporting vertical plates 1, and are used to wind up the lithium battery diaphragm 3 after the third stratification.
