Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically a novel screen mesh structure. Background Technology

[0002] Screen printing is an important step in the battery manufacturing process. It mainly involves printing patterns onto a blue film using a screen, squeegee, paste, and worktable. The squeegee uses pressure to squeeze the paste, which is then evenly penetrated into the battery cell to create the pattern. The purpose is to print on the front, back, sub-cells, main grid, electrodes, and electric fields of the battery cell. The printing is then carried out in an oven and curing furnace to complete the manufacturing process.

[0003] The existing screen printing mesh structure generally consists of three layers: latex mesh, stainless steel wire mesh, and latex mesh. In the existing screen printing process, the squeegee and the battery directly contact the latex mesh on both sides of the stainless steel wire mesh. Repeated friction causes the latex mesh to wear out and fall off quickly, resulting in a short service life. Utility Model Content

The mesh surface includes a first wear-resistant layer, a first latex mesh, a stainless steel wire mesh, a second latex mesh, and a second wear-resistant layer. The first wear-resistant layer, the first latex mesh, the stainless steel wire mesh, the second latex mesh, and the second wear-resistant layer are stacked sequentially from top to bottom. Ink-permeable holes are provided on both the first wear-resistant layer and the second wear-resistant layer.

[0013] (III) Beneficial Effects

[0014] This invention provides a novel screen mesh structure. It has the following beneficial effects:

[0015] 1. This new type of screen mesh structure, through the setting of a fully covered first wear-resistant layer and a second wear-resistant layer, ensures that during use, the scraper will contact the first wear-resistant layer and the battery cell will contact the second wear-resistant layer, thereby avoiding direct contact between the scraper and the battery cell and the latex mesh, improving the service life of the screen and reducing the screen production cost.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model embodiment provides a novel screen mesh structure, such as... Figure 1-2 As shown, it includes a frame 1 and a mesh surface installed inside the frame 1. The mesh surface includes a first wear-resistant layer 2, a first latex mesh 4, a stainless steel wire mesh 5, a second latex mesh 6, and a second wear-resistant layer 7. The first wear-resistant layer 2, the first latex mesh 4, the stainless steel wire mesh 5, the second latex mesh 6, and the second wear-resistant layer 7 are stacked sequentially from top to bottom. Both the first wear-resistant layer 2 and the second wear-resistant layer 7 have ink-permeable holes 3.

[0022] By using a fully covered first wear-resistant layer 2 and second wear-resistant layer 7, the scraper will contact the first wear-resistant layer 2 and the battery cell will contact the second wear-resistant layer 7 during use, thereby avoiding direct contact between the scraper and the battery cell and the latex mesh, improving the service life of the screen and reducing the screen production cost.

[0023] The first wear-resistant layer 2 and the second wear-resistant layer 7 have the same thickness and are made of the same material.

[0024] The thickness of the first wear-resistant layer 2 is not less than the thickness of the first latex mesh 4, and the thickness of the second wear-resistant layer 7 is not less than the thickness of the second latex mesh 6.

[0025] The first wear-resistant layer 2 completely covers the first latex mesh 4, and the second wear-resistant layer 7 completely covers the second latex mesh 6.

[0026] The first wear-resistant layer 2 and the second wear-resistant layer 7 are made of silicon carbide.

[0027] The first wear-resistant layer 2 and the first latex mesh 4 are fixedly connected, and the second wear-resistant layer 7 and the second latex mesh 6 are fixedly connected.

[0028] By fixing the first wear-resistant layer 2 and the first latex mesh 4 together, and fixing the second wear-resistant layer 7 and the second latex mesh 6 together, the overall structure can be improved, making the entire mesh more suitable for scenarios with high printing squeegee pressure.

[0029] Working principle: With the full coverage of the first wear-resistant layer 2 and the second wear-resistant layer 7, during use, the scraper will contact the first wear-resistant layer 2 and the battery cell will contact the second wear-resistant layer 7, thereby avoiding direct contact between the scraper and the battery cell and the latex mesh, improving the service life of the screen and reducing the screen production cost.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
