Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery grid structure. Background Technology

[0002] As is well known, the grids used in the manufacturing process of lead-acid battery plates are generally made into a single structure. Cutting is an essential step in the production of coated grids for single-plate designs. Currently, single-plate grids are generally connected longitudinally by connecting strips. When separating the plates, a roller cutter is needed to cut the connecting strip in the middle to achieve separation. The existing connecting strip is long and thin, running from the bottom of the top row of the grid to the top of the bottom row, with a height of 3-5mm and a length of 6mm between the upper and lower grids. In the current technology, manual cutting with a saw blade is usually used, which not only pollutes the environment and poses safety hazards, but also has low work efficiency. If this structure is used in an automatic roller shearing machine, there are problems: when both ends of the connecting strip are cut simultaneously, the connecting strip gets stuck between the two roller cutters of a cutting roller and is not easy to detach; if one end of the connecting strip is cut first and then the other end is cut, two cutting rollers are required, increasing the length and complexity of the equipment. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a battery grid structure.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A battery grid structure includes an upper grid group and a lower grid group connected by connecting tabs. The upper and lower grid groups have the same structure, both consisting of two rows of grid groups, each row of which is composed of multiple grids connected horizontally. The tabs of the upper and lower grid groups are vertically aligned and connected. Connecting tabs are provided between the lower row of grids in the upper grid group and the upper row of grids in the lower grid group. The connecting tabs are in a vertical "Z" shape. Each grid consists of an outer frame and grid-like ribs set inside the outer frame. The width 'a' of the upper half of the vertical frame of the outer frame is greater than the width 'b' of the lower half.

[0006] The battery grid structure has vertically arranged connecting pieces with a height of 12-15mm and a length of 10-12mm, and the protrusions on the top and bottom of the connecting pieces are both 4mm in length.

[0007] In the aforementioned battery grid structure, a distance of 4-33mm is left between the left side of the vertically arranged connecting piece and the left side of the lower row of grids in the upper grid group.

[0008] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0009] The battery grid structure described in this utility model features multiple "Z"-shaped connecting pieces between the upper and lower grid groups. Due to the structure and size of these "Z"-shaped connecting pieces, the grid can be placed on an automatic cutting machine for cutting, eliminating the need to add a cutting roller to the existing equipment. The vertical edges of the grid's outer frame have different widths at the top and bottom, with a structure that is wider at the top and narrower at the bottom. This reduces grid corrosion caused by current transmission at the top, thereby improving battery life. This utility model has a simple structure and is easy to use. It can achieve time-sharing cutting at both ends on a single cutting roller, improving work efficiency. Attached Figure Description

[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0015] Combined with appendix Figure 1-3 The battery grid structure includes an upper grid group 1 and a lower grid group 3 connected by connecting pieces 2. The upper grid group 1 and the lower grid group 3 have the same structure, both consisting of two rows of grids, one above the other. Each row of grids is composed of multiple grids connected horizontally. The tabs 4 of the upper and lower grids are vertically aligned and connected. Connecting pieces 2 are provided between the lower grid in the upper grid group 1 and the upper grid in the lower grid group 3. The connecting pieces 2 have a vertical "Z" shape structure. The height of the vertical connecting pieces 2 is 12-15mm, the length is 10-12mm, and the length of the protrusions on the upper and lower parts of the connecting pieces is 4mm. Each grid consists of an outer frame 5 and a grid-like rib set inside the outer frame 5. The width a of the upper half of the vertical frame of the outer frame 5 is greater than the width b of the lower half. There is a distance of 4-33mm between the left side of the vertical connecting piece 2 and the left side of the lower grid in the upper grid group.

[0016] Implementing the battery grid structure described in this utility model, taking the manufacturing of battery plates as an example, where both the upper and lower rows of grids are configured as four pieces connected left and right, as shown in the attached figure. Figure 1As shown, each row of grids is configured with four pieces. The upper and lower rows of grids are connected with corresponding tabs 4. A "Z"-shaped connecting piece 2 is provided between the lower row of grids in the upper grid group 1 and the upper row of grids in the lower grid group 3. The connecting piece 2 is 15mm high and 10.5mm long, with 4mm long protrusions on both the upper and lower sides. During slitting, two rotary blades are spaced apart in the middle of the automatic rotary shearing device, arranged circumferentially. The automatic rotary shearing device used in this invention is a circular... The cylindrical hob assembly has two hob blades that simultaneously cut at the upper and lower roots of the "Z"-shaped connecting piece 2. The "Z"-shaped connecting piece 2 then falls into the corresponding waste box at the bottom of the cylindrical hob assembly. Simultaneously, multiple long hob blades are arranged along the length of the cylindrical hob assembly, and these long hob blades are evenly spaced along the circumference of the assembly. During the rolling process of the cylindrical hob assembly, the multiple long hob blades cut and separate the four connected plates into individual plates; as shown in the attached diagram. Figure 2-3 As shown, the height of the grid in this invention is 71mm, the length of the tab 5 is 14.5mm, and the width of the grid is 44.3mm. The vertical frame of the outer frame 5 of the grid is wider at the top and narrower at the bottom. The upper width a of the vertical frame is 1.9mm, and the lower width b is 1.6mm, which effectively reduces grid corrosion caused by current transmission in the upper part, thereby improving battery life. The left side of the vertically arranged connecting piece 2 is 4-33mm away from the left side of the lower row of grids in the upper grid group. This prevents the connecting piece 2 from being too close to the long roller blade during cutting, which would cause interference with the connecting piece 2 and lead to bending at the corners of the grid. The cylindrical roller blade assembly is existing technology, and its specific structure and working principle will not be described in detail.

[0017] The parts of this utility model not described in detail are existing technologies.

[0018] The embodiments selected herein for the purpose of disclosing the inventive objectives of this utility model are currently considered appropriate; however, it should be understood that this utility model is intended to include all variations and modifications of the embodiments that fall within the scope of this concept and utility model.
