Description

Novel grid mesh belt arrangement structure

Technical Field

The invention relates to the field of storage battery production, in particular to a novel grid mesh belt arrangement structure.

Background

The grid is a key part of the storage battery, and the grid bears and supports active substances in the storage battery and plays a role in transferring current. With the rapid development of scientific technology, the traditional semi-mechanized cast grid is gradually replaced by continuous casting and rolling technology. In most of the continuous casting and rolling processes at present, two series of grids 1 are connected in series in a grid mesh belt, the tabs 2 of the grids 1 in the two series of grids 1 are arranged on the inner side of the grid mesh belt in a relatively staggered manner, and as shown in fig. 1, the bottom frames 3 of the two series of grids 2 are arranged on the outer side of the grid mesh belt in a back-to-back manner. The structure of the grid mesh belt has the following defects:

when the positions of the grid 1 except the lugs 2 in the grid mesh belt are required to be coated with the lead plaster, the lugs 2 of the two columns of the grid 1 are oppositely arranged on the inner side of the grid mesh belt, the lead plaster is inevitably extruded onto the lugs 2 when the lead plaster is coated, the lugs 2 are difficult to brush after the lead plaster is stained on the lugs 2, and the welding quality of the grid lugs in the subsequent process is seriously influenced.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides a novel grid mesh belt arrangement structure, which effectively improves the product quality and the qualification rate and realizes cost reduction and efficiency improvement by reasonably designing the arrangement and connection structure of grids on grid mesh belts.

The technical scheme is as follows: the invention provides a novel grid mesh belt arrangement structure which is formed by horizontally connecting two rows of a plurality of grids connected in series, wherein the lugs of the two rows of grids connected in series are arranged on the outer side of the structure in a back-to-back manner; the two series-connected grids are arranged on the inner side of the structure, and the two grid bottom frames which are arranged oppositely are connected through staggered connecting blocks with different heights at two ends.

Furthermore, the two ends of the two adjacent dislocation connecting blocks are arranged in a vertically staggered manner. If the upper end of the previous dislocation connecting block is connected with the lower part of the grid bottom frame on the upper side and the lower end is connected with the upper part of the grid bottom frame on the lower side, the upper end of the next dislocation connecting block is designed to be connected with the upper part of the grid bottom frame on the upper side, and the lower end is designed to be connected with the lower part of the grid bottom frame on the lower side; because the two ends of the staggered connecting block are different in height, the thickness of the two ends of the staggered connecting block needs to be smaller than the thickness of the frame at the bottom of the grid, and the strength of the staggered connecting block is possibly lower.

Furthermore, the lugs of the two series-connected grids are respectively connected and fixed through connecting strips. If the connecting strips are not arranged, the lugs of the two rows of grids are suspended, so that the lugs are easy to deform.

Preferably, the dislocation connecting block is in a Z-shaped structure. The dislocation connecting block of this kind of structure can make the cutting knife follow the grid smear feeding and prevent the line and successively cut the tie point of dislocation connecting block and two upper and lower rows of grids, compares with the connecting block of straight shape, can effectively avoid the cutter to cut off the back with the tie point of both sides simultaneously, and the connecting block is blocked and is gone on smoothly between two cutting knives, influences follow-up cutting process.

Preferably, the thickness of the offset connector block does not exceed 1/2 the thickness of the bottom frame of the grid. The thickness of dislocation connecting block only when not exceeding 1/2 of grid bottom frame thickness, just can guarantee that the hobbing cutter is not the cutting simultaneously when cutting the even end of dislocation connecting block, effectively avoids the production of hobbing cutter card problem.

Has the advantages that: compared with the prior art, the invention has the following advantages:

(1) the two series of the lugs of the grid are arranged on the outer side of the grid mesh belt, so that lead plaster can be effectively prevented from being extruded to the lugs of the grids on two sides when the grids are coated with the lead plaster.

(2) Connecting the bottom frames of the grids in two rows of series-connected grids through a staggered connecting block, so that when a grid mesh belt is fed along the feeding direction of a grid smear, the rolling cutters used for cutting two ends of the staggered connecting block firstly cut the connection point between the end with higher height in the staggered connecting block and the bottom frame of one row of grids, and then cut the connection point between the end with lower height in the staggered connecting block and the bottom frame of the other row of grids; because the both ends of dislocation connecting block and the tie point of two grid bottom frames are not cutting simultaneously, can effectively avoid because the connecting block that cuts that the cutting caused simultaneously falls is blocked the defect between two cutting knives for subsequent cutting can go on smoothly.

(3) The grid mesh belt structure can effectively avoid the problems of grid deformation, clamping during slicing, residual paste of lugs and the like in the production process, greatly reduces the rejection rate of the grid and improves the product quality.
