Abstract

An accumulator grid with ear ranges in storage battery technical field and for solving the problem of high rejection ratio of plates, comprising of a grid and an ear. The ear is positioned on the upper of the two sides in width of the grid, which is connected with the ear by hollow-out-hole point connection. The utility model changed the traditional linear connection to hollow-out-hole point connecting and from the mechanical dividing to manual splice, reducing the mechanical shock in splicing. With the reformation, the condition of loosen and shedding of the lead plaster near the ear improved greatly, and the ratio reduced from the original 3% to now 0.8%. The utility model has the advantages of less investment, quick results, and easy realization, void of the equipment innovation and very useful.

Description

A kind of battery grid that has the board ear

Technical field

The utility model relates in a kind of vehicle battery, particularly lead acid accumulator, the board structure of thick template grid, belongs to the battery technology field.

Background technology

Grid is used for supporting active material and electric current is uniformly distributed on the active material in battery, thereby improves active material utilization.The active material of porous, especially positive active material brown lead oxide are a kind of soft subparticles that is difficult to bond together, and easy-formation not, grid can be used for supporting active material and form pole plate as skeleton.

Between active material and the grid, be that the corrosion layer that forms when solidifying by green plate connects, the thickness of corrosion layer has determined the intensity that connects between the two, but the thickness of corrosion layer is unsuitable excessive, otherwise will influence the discharge performance of battery.Therefore being connected between active material and the grid is unstable, and when external force collision or vibrations, bonding strength descends rapidly or disconnects.

Usually storage battery production enterprise need design tens kinds at least, tens kinds at most, the grid of hundreds of different width dimensions, these grids, when different production processes such as age-hardening, coated plate, curing, need to use the moulds of industrial equipment that are complementary with its width dimensions,, reduce cost for improving the versatility of moulds of industrial equipment, on grid, designed the board ear, on grid unification to a size with various width dimensions.

Before the battery assembling, need remove the plate ear, according to adopting the wire connected mode between existing grid and the board ear; need amputate the plate ear by means of saw-blade type board separator or roller shear formula board separator; machinery divides the mechanical oscillation in the plate operation, and regular meeting causes that near the lead plaster the plate ear is loose or comes off, causes useless plate.For this reason, seek a kind of simple and easy to do method, divide the plate percent defective for reducing, cut the waste, be highly significant.

Summary of the invention

The utility model is used to overcome the defective of prior art and employing point-like connected mode between a kind of grid and the board ear is provided, thereby reduces the battery grid that has the board ear that divides the plate percent defective.

The alleged problem of the utility model is that following technical scheme solves:

A kind of battery grid that has the board ear, it is made up of grid and plate ear, and described plate ear is positioned at the dual-side top of grid Width, and its special feature is: be connected for hollow out cellular type point-like between described plate ear and the grid.

The above-mentioned battery grid that has the board ear, tie point is 2～6 points between described every side plate ear and grid.

The utility model is at the syndeton between existing battery grid and the board ear, the problem that near when easily causing the branch plate plate ear lead plaster loosens or comes off, percent defective is high is improved, it changes traditional wire connection into hollow out formula point-like type of attachment, divide plate to change the manual plate that divides into by machine, thereby reduced the mechanical shock that divides in the plate process, divide in the plate process that lead plaster phenomenon loose or that come off is greatly improved near the plate ear, percent defective is reduced to 0.8% by original 3%.The utlity model has and drop into little, instant effect, easily realize, do not relate to advantages such as scrap build, so have practicality.

Description of drawings

Fig. 1 is the utility model schematic diagram.

The label of each parts is expressed as follows in the accompanying drawing: 1. grid; 2. plate ear; 3. hollow hole.

Embodiment

Referring to Fig. 1, plate ear described in the utility model is a kind of process structure in the accumulator plate production process, it is positioned at the dual-side top of grid 1 Width, be connected for hollow out formula point-like between plate ear 2 and the grid 1, hollow hole 3 is evenly distributed on the plate ear, considers that from the angle of bonding strength tie point is 2～6 points between every side plate ear and grid, generally can establish 3 points, two hollow holes promptly are set.This structure satisfies on the basis of technology bonding strength in assurance, changing traditional wire connection (being that entity connects) is that point-like connects, the improvement back is corresponding can divide machinery the plate operation to change the manual plate that divides into, and the lead plaster of having avoided being caused by mechanical oscillation loosens or comes off, and percent defective reduces greatly.

Claims

1. battery grid that has the board ear, it is made up of grid and plate ear, and described plate ear position (2) is characterized in that in the dual-side top of grid Width: be connected for hollow out cellular type point-like between described plate ear and the grid.

2. the battery grid that has the board ear according to claim 1 is characterized in that: tie point is 2～6 points between described every side plate ear (2) and grid (1).
