Description

Multi-sheet grid connection structure

[ technical field]A method for producing a semiconductor device

The utility model relates to a grid of positive and negative polar plate of battery, in particular to grid connection structure of positive and negative polar plate of battery.

[ background of the invention]

The positive active material of lead-acid accumulator is lead dioxide, the negative active material is spongy lead, and the electrolyteThe electrolyte is a dilute sulfuric acid solution, the discharge chemical reaction of the dilute sulfuric acid solution is that lead dioxide and spongy lead react with the electrolyte to generate lead sulfate and water, (discharge reaction) the charging chemical reaction is that lead sulfate and water are converted into lead dioxide, spongy lead and dilute sulfuric acid. The rated voltage of the lead-acid storage battery unit grid is 2.0V, the lead-acid storage battery unit grid is generally connected in series to be 6V and 12V for starting illumination of automobiles and motorcycles, and the lead-acid storage battery unit grid is generally connected in series to be 36V, 48V, 96V, 110V or 220V for different occasions. A high-porosity baffle made of rubber, PVC, PE or AGM and allowing stable ions to pass through is arranged between the positive plate and the negative plate in the battery.

The manufacturing process flow of the lead-acid storage battery comprises the main steps of lead powder manufacturing, grid manufacturing, green plate manufacturing, plate formation, washing and drying, battery assembly and the like. The casting of the grid is an important link, and the quality, the thickness, the integrity, the geometric size and the like of the grid can greatly influence the processing difficulty of the subsequent process and the performance of the battery.

At present, several or even more than ten grids are connected together for production, and then the produced multiple polar plates are cut, so that the production efficiency can be greatly improved and is several times or even tens times higher than that of single-plate production, and the multiple grids are cut by adopting a special cutter. At present, the connection structure of the grid has two types: one is that the single plate grids are connected by plates, namely all the single plate grids are connected by solid, so that the abrasion to a cutter is large during cutting, the service life of the cutter is reduced to the ground, and a large amount of raw materials are wasted at the same time, because all the solid connections need to increase a large amount of lead materials; the other is that the grids are connected by ribs, because the distance between the grids is 2.0mm (namely the length of the ribs is 2.0mm), and the thickness of the cutter is 1.6-1.8mm, if the cutter can be accurately positioned, no redundant ribs are basically arranged on the edge of the cut grid, but in the actual cutting process, the polar plate is slightly deformed, the positioning of the cutter is not accurate basically, certain deviation can be generated, and the cutter often deviates to one side, so that one grid can be cut and damaged, the plate edge of the other grid has redundant ribs (burrs), and the plate is attached with active substances, the removal of the redundant ribs (burrs) and the active substances is difficult, and the waste of labor is caused even if the grid can be cleaned, the production cost is increased, and the removed dust can also have certain influence on the environment, if the redundant ribs and active matter dust are not removed or are not completely removed, short circuit or micro short circuit fault of the assembled storage battery can be caused.

Therefore, how to adopt the most effective structure to realize the connection of multiple grids, so that the connection is cost-saving and convenient to cut becomes an important subject of research of storage battery manufacturing enterprises.

[ summary of the invention]

The utility model aims at solving the problem in the prior art, providing a connection structure of multi-disc grid, both saved the cost and made things convenient for the cutting, can not produce unnecessary rib.

In order to achieve the above object, the utility model provides a multi-disc grid connection structure, including the frame cross-section and the connecting rib of connecting the frame cross-section, still include a plurality of enhancement limits, the setting of enhancement limit is close to one side of connecting rib on the frame cross-section.

Further, the reinforcing edge is in a triangular row shape extending outwards along one edge of the section of the frame.

Furthermore, each frame section is provided with two reinforcing edges.

Further, the section of the frame is in a regular hexagonal row shape.

Further, the length of the connecting ribs is 1.2 mm.

The utility model has the advantages that: the utility model adds the reinforcing edge on the cross section of the frame, which saves a large amount of raw materials compared with the original plate connection mode, greatly reduces the abrasion to the cutting tool and greatly reduces the damage to the active matters; only a little raw materials are added on the basis of original rib connection, the problem of deviation of a cutter during cutting is solved, redundant ribs (burrs) and active matters cannot be generated even if the cutter deviates during cutting, the cutting loss of a grid cannot be caused, the labor cost for removing the redundant ribs and the active matters is greatly saved, the pollution to the environment is reduced, and the short circuit or the micro short circuit of a storage battery caused by the redundant ribs (burrs) is also eliminated.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.

[ detailed description]embodiments

FIG. 1 is a schematic diagram of a board connection structure in the prior art; the connecting plates 12 are used for connecting the frame sections 11, the connecting area is large, raw materials are wasted, the whole plate needs to be sawed by a cutter during cutting, the cutting speed is not high, the cutter is greatly abraded, and active substances are greatly damaged. Fig. 2 is a schematic structural diagram of rib connection in the prior art; adopt connecting rib 22 to connect between each frame cross-section 11, can save a lot of raw and other materials like this to the cutting is also more convenient, however, because the skew of cutter can produce unnecessary rib (burr) and active matter dust often, will increase a large amount of manual works and clear away, if clear away incompletely, can cause whole battery short circuit or little short circuit trouble even.

Fig. 3 is a schematic structural view of the connection of the reinforcing ribs of the present invention; this utility model discloses a plurality of enhancement limits 32 increase again on the basis that original rib is connected. The reinforcing rim extends outwardly along one edge of the rim section 11 and part of the connecting rib 22. The shortest distance between the frame sections 11 is 2.0mm, the preferred embodiment of the reinforcing edges 32 is triangular in shape, which extends about 0.4mm in the direction of the connecting ribs 22, since the reinforcing edges 32 of 0.4mm extend on both sides, so that the length of the connecting ribs 22 only needs to be about 1.2mm, and the thickness of the cutting tool is 1.6mm, so that even if there is a slight deviation during cutting, no excess connecting ribs 22 are produced, since the length of the connecting ribs 22 is much smaller than the thickness of the tool. The effect is further improved by providing the reinforcing beads 32 only on the upper or lower portion of the frame section 11, or by providing two reinforcing beads 32 on the upper or lower portion of the frame section 11 at the same time. The frame section 11 has a regular hexagonal shape, but may have other similar shapes. The utility model discloses it is fine to implement the back effect.
