Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production technology, and in particular to a split cavity structure. Background Technology
[0002] The laser cutting cavity is the only area besides the slitting blade that generates dust in a die-cutting machine. To control the dust generated during laser cutting and ensure the overall cleanliness of the equipment meets requirements, the laser cutting cavity is typically designed as a four-sided enclosed structure. The front and rear cavities act like two boxes, sandwiching the electrode in between. Air blowing and suction are added to the remaining two opposite sides to exhaust the dust. To ensure that the dust is confined within the cavity as much as possible, the gap between the cutting cavity and the electrode is usually very small. However, this design hinders the electrode threading process. Utility Model Content
[0003] The main objective of this invention is to provide a separate cavity structure to solve the above-mentioned technical problems. The operation guide structure drives the rear cavity structure away from the front cavity, thereby increasing the gap between the front and rear cavity structures, so as to facilitate the operator to thread the electrode and improve the operator's maintenance efficiency.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A split cavity structure includes a fixed plate, a front cavity, a rear cavity structure, and a guide structure. The front cavity is fixed to the fixed plate, the guide structure is mounted on the side end face of the fixed plate, and the rear cavity structure is mounted on the guide structure. Operating the guide structure causes the rear cavity structure to move relative to the front cavity.
[0006] As a preferred technical solution, the guide structure includes a guide mounting plate, a guide rod, and a handle. The rear cavity structure and the handle are mounted on the guide mounting plate. One end of the guide rod is fixed to the end face of the guide mounting plate and is positioned opposite to the handle. The guide rod passes through the fixed plate.
[0007] As a preferred technical solution, the rear cavity structure includes a rear cavity mounting plate and a rear cavity. The rear cavity mounting plate is fixed on the guide mounting plate, and the rear cavity is fixed in the rear cavity mounting plate and aligned with the front cavity.
[0008] As a preferred technical solution, the rear cavity structure further includes a partition plate, which is fixed to the rear cavity mounting plate and positioned between the rear cavity and the fixing plate.
[0009] As a preferred technical solution, a magnet is provided on the fixing plate, and the magnet is fixed on the side of the fixing plate and close to the guide structure.
[0010] The beneficial effects of this utility model are as follows: In the above-mentioned split cavity structure, the front cavity and the rear cavity structure are connected to negative or positive air pressure. The positive air pressure is used to blow the dust adhering to the electrode sheet in a directional manner, and the negative air pressure is used to adsorb the flying dust, so as to achieve dust adsorption and collection. The operation guide structure drives the rear cavity structure to move relative to the front cavity, so that the rear cavity structure can move closer to the front cavity during laser cutting, ensuring that the dust can be confined as much as possible between the front cavity and the rear cavity structure, avoiding dust flying or adhering to the electrode sheet, which would affect the pass rate of cell production. When an emergency such as electrode sheet breakage occurs and re-tape is required, the operation guide structure drives the rear cavity structure away from the front cavity, thereby increasing the gap between the front cavity and the rear cavity structure, so as to facilitate the operator to re-tape the electrode sheet and improve the maintenance efficiency of the operator.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0015] Please combine Figure 1 , Figure 2 and Figure 3As shown, a split-cavity structure includes a fixed plate 1, a front cavity 2, a rear cavity structure 3, and a guide structure 4. The front cavity 2 is fixed to the fixed plate 1, the guide structure 4 is mounted on the side end face of the fixed plate 1, and the rear cavity structure 3 is mounted on the guide structure 4. The front cavity 2 and the rear cavity structure 3 are connected to negative or positive air pressure. Positive air pressure is used to blow dust adhering to the electrode in a directional manner, and negative air pressure is used to adsorb the flying dust, thereby achieving dust adsorption and collection. Operating the guide structure 4 moves the rear cavity structure 3 relative to the front cavity 2. The cavity 2 moves so that the rear cavity structure 3 can move closer to the front cavity 2 during laser cutting, ensuring that dust is confined between the front cavity 2 and the rear cavity structure 3 as much as possible, preventing dust from flying or adhering to the electrode sheet, which would affect the pass rate of cell production. When an unexpected situation such as electrode sheet breakage occurs and re-tapping is required, the operation guide structure 4 moves the rear cavity structure 3 away from the front cavity 2, thereby increasing the gap between the front cavity 2 and the rear cavity structure 3, making it easier for operators to re-tape the electrode sheet and improving the maintenance efficiency of operators.
[0016] The guide structure 4 includes a guide mounting plate 42, a guide rod 43, and a handle 41. The rear cavity structure 3 and the handle 41 are mounted on the guide mounting plate 42. One end of the guide rod 43 is fixed to the end face of the guide mounting plate 42 and is positioned opposite to the handle 41. The guide rod 43 passes through the fixed plate 1. Pulling or pushing the handle 41 causes the guide mounting plate 42 to move along the guide rod 43, thereby causing the rear cavity structure 3 to move relative to the front cavity 2, so as to increase or decrease the distance between the rear cavity structure 3 and the front cavity 2.
[0017] The rear cavity structure 3 includes a rear cavity mounting plate 31, a rear cavity 32, and a partition plate 33. The rear cavity mounting plate 31 is fixed on the guide mounting plate 42, and the rear cavity 32 is fixed in the rear cavity mounting plate 31 and aligned with the front cavity 2. The partition plate 33 is fixed on the rear cavity mounting plate 31 and positioned between the rear cavity 32 and the fixing plate 1. The partition plate 33 is made of metal and is used to separate the rear cavity 32 and the fixing plate 1, preventing direct contact and friction between them. Specifically, a magnet 11 is provided on the fixing plate 1. The magnet 11 is fixed on the side of the fixing plate 1 and close to the guide structure 4. When the rear cavity structure 3 needs to be close to the front cavity 2, the magnet 11 attracts the guide mounting plate 42 to fix the rear cavity structure 3, preventing movement of the rear cavity structure 3 during electrode welding and affecting the dust removal effect.
[0018] The embodiments described above are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of this utility model patent application.
