Abstract
The invention discloses a storage battery burn-in and poor soldering prevention device which comprises a fixed die plate, a moving die plate and a mound layer, wherein post positioning grooves and busbar grooves are formed in each of the fixed die plate and the moving die plate; a plurality of tooth grooves are formed each busbar groove, and gaps A are formed between the length directions of the tooth grooves and the edge parts of the busbar grooves; the mound layer is composed of a left mound layer and a right mound layer, a wane groove is formed in the left mound layer, and a boss is arranged on the right mound layer; the wane groove is buckled with the boss and connected with the boss through a rotating shaft; a gap B is formed between a busbar and the edge of the mound layer. The storage battery burn-in and poor soldering prevention device has the advantages of simple structure and convenience in operation, ensures that a tab of the busbar is not exposed, enhances the binding force of the tab and the busbar, avoids the phenomenon that the product quality declines as the tab deforms by beating the mound layer, is low in repair rate, and improves burn-in quality and production efficiency.
Description
Technical field
the present invention relates to storage battery production field, be specifically related to a kind of electricity storage preventing pond and freeze the device of rosin joint.
Background technology
Polar-group welding operation in storage battery manufacture process first pole group is contained on comb mould, then beats press strip and make it compress between positive negative norm then to freeze.Press strip is pressed in the middle of positive negative bus, the both sides of press strip are close to the edge of positive and negative lug, not reserved welding surplus gap, the lug being close to press strip limit is difficult to grill thoroughly, easy rosin joint is exposed, causes to freeze defective, needs again pole group to be contained on the mould that freezes to carry out reprocessing repair welding, time-consuming expense, affects production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electricity storage preventing pond and freezes the device of rosin joint, structure is simple, easy to operate, ensure that the lug of bus-bar does not expose, enhance the adhesion of lug and strap, and avoid beaing press strip and cause lug to be out of shape the generation causing product quality decline phenomenon, repair rate is low, improves freeze quality and production efficiency.
The present invention is achieved through the following technical solutions:
Freeze the device of rosin joint in a kind of electricity storage preventing pond, comprise solid plate, moving platen and press strip, described solid plate and moving platen are provided with and are equipped with pole location notch and busbar channel, are provided with some teeth groove in busbar channel, and teeth groove length direction and busbar channel edge leave A gap; Described press strip is made up of left and right press strip, and left press strip is provided with short slot, and right press strip is provided with boss, and short slot engages with boss, and be provided with rotating shaft in the middle of both and connect, the relative bus-bar edge of described press strip is provided with B gap.Leave gap, can lug be grilled thoroughly during welding, not easily produce rosin joint; Left and right press strip is that angle state is put between two row's lugs, presses press strip and makes it to set level, and can promote left and right press strip and compress lug, avoids beaing press strip in the past and causes the loose lead powder of lug bottom to come off.
The further improvement project of the present invention is, the gap clearance in described A gap and B gap is 0.5-2mm.
The present invention further improvement project is, described A gap and B gap are slope, the rectangular triangle of end section.Leave gap and can increase the plumbous amount of bus-bar consumption, the plumbous amount of consumption is reduced in slope gap as far as possible.
The present invention further improvement project is, described press strip side is provided with location notch, and solid plate is provided with the alignment pin of coupling.
The present invention further improvement project is, described press strip both sides are provided with handle.Conveniently take out press strip.
The present invention compared with prior art, has following obvious advantage:
Structure of the present invention is simple, easy to operate, ensure that the lug of bus-bar does not expose, enhance the adhesion of lug and strap, and avoid beaing press strip and cause lug to be out of shape the generation causing product quality decline phenomenon, repair rate is low, improves freeze quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is assembling plan view of the present invention.
Fig. 2 is that cutaway view is looked on apparatus of the present invention left side.
Fig. 3 is that cutaway view is looked on a press strip left side of the present invention.
Embodiment
As shown in Figure 1 to Figure 3, the present invention includes solid plate 1, moving platen 2 and press strip 3, described solid plate 1 is provided with moving platen 2 and is equipped with pole location notch 11,21 and busbar channel 12,22, some teeth groove 13,23 are provided with in busbar channel, teeth groove length direction and busbar channel edge leave A gap 14,24, and gap clearance is 0.5-2mm; Described press strip 3 is made up of left and right press strip, and left press strip 31 is provided with short slot 311, and right press strip 32 is provided with boss 322, short slot 311 engages with boss 322, be provided with rotating shaft 33 in the middle of both to connect, described press strip 3 is provided with B gap 34 in bus-bar edge relatively, and gap clearance is 0.5-2mm.
Described A gap 14,24 and B gap 34 are slope, the rectangular triangle of end section.
Described press strip 3 side is provided with location notch 35, and solid plate 1 is provided with the alignment pin 15 of coupling.
Described press strip 3 both sides are provided with handle 36.
Operation principle: first the lug 4 of group side, pole is inserted in the teeth groove of side solid plate, load onto opposite side moving platen 2 simultaneously, by press strip 3(gravitate state in a certain angle, see Fig. 3) put between two row's lugs, press press strip and make it placement level, left and right press strip can be promoted and compress lug, this compresses the action of lug, avoid and beat press strip in the past and cause the loose lead powder of lug bottom to come off, cause the generation of product quality decline phenomenon, and then freeze, having welded rear upper handle 36 makes left and right press strip in a certain angle, press strip can be taken out, unload pole group.
Before and after process certification contrast improves the mould that freezes respectively, lug is exposed has done process ration, and experiment content comprises: the problem points before and after improving, defective products ratio, Contrast on effect.
| ? | Problem points | Defective products ratio | Contrast on effect |
| Before improvement | Lug rosin joint is exposed | 17% | Occupy ratio large, reprocess and waste time and energy |
| After improvement | Lug rosin joint is exposed | 1% | Improve obviously, repair rate is low, enhances productivity |
From process certification effect, before and after the mould that freezes improves, Contrast on effect is obvious especially, and lug rosin joint is exposed has dropped to 1% from original 17%, and production efficiency improves 16%.
