Description

Technical Field

[0001] This invention belongs to the technical field of lead-acid battery stamped lead mesh structure, specifically relating to a double-piece symmetrical non-uniform structure of continuously stamped lead mesh for lead-acid batteries. Background Technology

[0002] Lead-acid battery meshes are conventionally designed to be uniform, with mirror symmetry being the primary feature in dual-cell designs. Non-uniform grid structures are generally used in gravity-cast grids. However, the continuous stamping process for lead mesh production differs from gravity casting, and the arrangement of non-uniform structures presents multiple technical challenges that were previously difficult to achieve. After years of technological breakthroughs, both mirror symmetric and non-uniform structures can now be freely designed and manufactured. Summary of the Invention

[0003] To achieve the above objectives, the technical solution of the present invention is as follows: a double-piece symmetrical non-uniform structure for continuously stamping lead mesh in a lead-acid battery. The structure includes a double-piece symmetrical structure and a group of punching structures with different widths and punch sizes. The double-piece symmetrical structure consists of two mirror-symmetrical grid structures with a central bottom frame as the axis. On a single grid plate, the punched mesh grid shape is a horizontally narrow and vertically long rectangular structure. The horizontal ribs on the plate surface have consistent dimensions, while the vertical rib dimensions increase from small to large with increasing punch size, and the width of the vertical ribs decreases from wide to narrow, achieving a gradual change in the vertical rib width. This is technically achieved by using different groups of punch sizes corresponding to different positions on the plate surface to achieve a non-uniform structure.

[0004] Based on the above technical features, the dual-plate symmetrical structure is a grid structure of two plates that are mirror-symmetrical about the middle bottom frame. Its purpose is to obtain two plates with the same structure when the coating plate is cut.

[0005] As an improvement of the present invention, the symmetrical structure of the double-piece symmetrical structure includes a first group of punching structures, a second group of punching structures, a third group of punching structures and a fourth group of punching structures. The first group of punching structures, the second group of punching structures, the third group of punching structures and the fourth group of punching structures form a symmetrical structure on half of the double-piece symmetrical structure and radiate outward to form a non-uniform structure.

[0006] Based on the above technical features, the structure includes a double-piece symmetrical structure and four different rib widths and punching sizes: a first group of punching structures, a second group of punching structures, a third group of punching structures, and a fourth group of punching structures. The purpose is to increase the conductivity of the upper half of the plate surface. As an improvement of the present invention, the half-structure of the double-piece symmetrical structure includes eight rows of punches designed on each half, wherein the eighth row is close to the axis of symmetry and radiates outward, with four different rib widths and punching sizes, wherein the first and second rows are the first group of punching structures, the third and fourth rows are the second group of punching structures, the fifth, sixth and seventh rows are the third group of punching structures, and the eighth row is the fourth group of punching structures, forming a non-uniform structure.

[0007] As an improvement of the present invention, the first group of punching structures formed by the first and second rows of the four rib widths and punching sizes is close to the upper edge of the electrode lug, and the vertical rib width is 0.2mm wider than the conventional design.

[0008] As an improvement of the present invention, the second group of punching structures formed by the third and fourth rows of the four rib widths and punching sizes is located near the upper middle part of the plate surface, and the width of the vertical ribs is 0.1mm wider than that of the conventional design.

[0009] As an improvement of the present invention, the third group of punching structures formed by the fifth, sixth and seventh rows of the four rib widths and punching sizes is located near the lower middle part of the plate surface.

[0010] Based on the above technical features, the width of its vertical ribs is a conventional design.

[0011] As an improvement of the present invention, the fourth group of punching structures formed by the eighth row of the four rib widths and punching sizes is close to the bottom of the plate. Its punching length is redundant due to the non-integer divisibility of the design size, and is longer than other punches.

[0012] Based on the above technical features, the width of its vertical ribs is a conventional design.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This application provides a double-piece symmetrical non-uniform structure for continuous stamping of lead mesh in lead-acid batteries, which solves the problem of low internal resistance when current converges to the tab during high current discharge, increases the width of the ribs at the root of the tab, makes the corrosion of the ribs in each area basically uniform, reduces the risk of corrosion and breakage at the root of the tab, and thus increases the cycle life of the battery.

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0017] Example: See Figure 1 and Figure 2 , Figure 1 It is a double-sheet symmetrical non-uniform structure of continuously stamped lead mesh, made of lead.

[0018] This embodiment is a double-piece symmetrical non-uniform structure for continuously stamping lead mesh for lead-acid batteries. In the symmetrical structure 1 of the double-piece symmetrical structure, each half is designed with 8 rows of punches, with the 8th row being closer to the axis of symmetry and radiating outwards. There are 4 different rib widths and punch sizes: the first group of punch structures 2, the second group of punch structures 3, the third group of punch structures 4, and the fourth group of punch structures 5. The 1st and 2nd rows are the first group of punch structures 2 with a size of 13.63mm × 4.03mm, the 3rd and 4th rows are the second group of punch structures 3 with a size of 13.63mm × 4.13mm, the 5th, 6th, and 7th rows are the third group of punch structures 4 with a size of 13.63mm × 4.23mm, and the 8th row is the fourth group of punch structures 5 with a size of 12.13mm × 4.23mm, forming a non-uniform structure.

[0019] Furthermore, in the first and second rows, which are near the upper edge of the electrode tab, the width of the vertical rib is 1.2mm, which is 0.2mm wider than the conventional design of 1.0mm, and the punch size is 13.63mm × 4.03mm.

[0020] Furthermore, in the third and fourth rows, which are one of the four types of rib widths and punching sizes, the vertical rib width of 1.1mm is 0.1mm wider than the conventional design of 1.0mm, and the punching size is 13.63mm × 4.13mm.

[0021] Furthermore, for the 5th, 6th, and 7th rows, which are located near the lower middle part of the board, the vertical rib width of 1.0mm is a conventional design, and the punch size is 13.63mm × 4.23mm.

[0022] Furthermore, in the 8th row, which is one of the four types of rib widths and punching sizes, near the bottom of the board, the vertical rib width of 1.0mm is a conventional design, but the punching length is redundant because the design size is not divisible by an integer, and the punching size is 12.13mm × 4.23mm.

[0023] It should be noted that the above content merely illustrates the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, various improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
