Description

Technical Field

[0001] The invention relates to the technical field of battery plate processing, and in particular to an automatic pressing device for a plate and a processing method thereof. Background Art

[0002] like Figure 1 As shown, a battery plate 8 in the prior art is shown, and the battery plate 8 includes a plate silver mesh 81 located in the middle and zinc powder layers 82 located on both sides of the plate silver mesh 81, wherein the zinc powder layer 82 is formed by laying zinc powder on the side of the plate silver mesh 81 and pressing it. During the production process of the battery plate 8, it is necessary to keep the plate silver mesh 81 within a good flatness range, and then press a layer of dense zinc powder layer 82 on both sides of the plate silver mesh 81 to form a final battery plate 8 product. In factories, the plate silver mesh 81 is usually loaded manually. While loading the plate silver mesh 81, the flatness of the plate silver mesh 81 is checked by naked eyes, and the plate silver mesh 81 with a larger deformation is removed. However, this manual removal method wastes manpower, and a large part of the plate silver mesh 81 that is usually removed is only caused by a slightly larger bending deformation. This part of the plate silver mesh 81 will still be flattened to the standard flatness range and continued to be used. However, this screening process and subsequent defective product processing process are relatively cumbersome and are not conducive to industrial continuous production. In addition, different types of battery plates 8 have different requirements for the thickness of the zinc powder layer 82. For this reason, the factory often needs to be equipped with multiple mold equipment with different cavity depths to produce battery plates of different thicknesses. This will cause multiple mold equipment to occupy a large space, which needs to be improved urgently. Summary of the invention
