Abstract
The utility model discloses a lithium cell package welding jig, including the box body formula anchor clamps bodies, press from both sides specific both sides in the box body formula and be provided with according to certain interval and weld the needle locating hole more than two, be provided with in the centre of welding the needle locating hole and weld the needle baffle, box body formula anchor clamps body lower extreme and isolated trench's inner wall clearance fit presss from both sides specific top in the box body formula simultaneously and still is provided with hydraulic push rod. The utility model discloses a welding jig is last welds the needle locating hole and fixes a position the welding point that the lithium cell was wrapped, in order to control gap width between the two root bead needles well, has set up in welding the needle locating hole and has welded the needle baffle simultaneously to effectively avoid a root bead needle to contact two metal mica sheets simultaneously, avoid the lithium cell among the welding process short circuit phenomenon to appear, can improve the welding efficiency of lithium cell package greatly, improve to change and weld the difficult problem of needle, reduce technician's work load.
Description
Technical field
The utility model relates to a kind of lithium battery bag weld jig, belongs to lithium battery bag welding technology field.
Background technology
Being made up of a joint joint lithium battery series and parallel of lithium battery bag, the connection of two batteries is welded together by spot-welding technology with metal mica sheet, thus increases capacity and the voltage of power brick.During welding, first stretched out by capillary and to contact with metal mica sheet and to extrude, when pressure reaches the pressure preset, metal mica sheet point is welded in the two poles of the earth of lithium battery through capillary by the electric current that butt-welding machine discharges rapidly a few kilo-ampere.In welding process, capillary often can black by burning, puncture, simultaneously capillary also has wearing and tearing, touches disconnected phenomenon, and this just needs often to change capillary.See Fig. 3, the centre due to metal mica sheet offers a breach, and the capillary therefore on butt-welding machine needs to arrange in pairs, is just welded on lithium battery the two poles of the earth by the metal mica sheet of breach both sides like this when welding simultaneously.But, change in the process of capillary, not only will ensure on the metal mica sheet that capillary just in time can be pressed onto between lithium battery, but also will control the gap width between two root bead pins well, two panels metal mica sheet can not be contacted by a root bead pin simultaneously, avoid the lithium battery in welding process to occur short circuit phenomenon.Existing technology repeatedly goes for by experienced technical staff the contact position seeking two root bead pins and metal mica sheet, go afterwards to debug the pressure between capillary and metal mica sheet, this replacing options causes the replacing of capillary to bother very much, waste a lot of time, affect the production efficiency of lithium battery bag.
Summary of the invention
The purpose of this utility model is, a kind of lithium battery bag weld jig is provided, thus greatly can improves the welding efficiency of lithium battery bag, improve the problem changing capillary difficulty, reduce the workload of technician, and can effectively avoid the lithium battery in welding process to occur short circuit phenomenon.
The technical solution of the utility model: a kind of lithium battery bag weld jig, comprises box-type clamp body, in the both sides of box-type clamp body, certain spacing is provided with plural capillary locating hole, the centre of capillary locating hole is provided with capillary dividing plate.
Aforesaid weld jig also comprises insulation tank, the inwall matched in clearance of box-type clamp body lower end and insulation tank, is also provided with hydraulic mandril at the top of box-type clamp body simultaneously.
Aforesaid capillary dividing plate adopts insulating materials to make.
Owing to adopting technique scheme, the utility model has the advantage of: the pad that the utility model adopts capillary locating hole to wrap to locate lithium battery, gap width simultaneously in order to control well between two root bead pins, capillary dividing plate is provided with in capillary locating hole, thus effectively avoid a root bead pin to contact two panels metal mica sheet simultaneously, the lithium battery in welding process is avoided to occur short circuit phenomenon, the welding efficiency of lithium battery bag can be improved widely, improve the problem changing capillary difficulty, reduce the workload of technician.Therefore, the utility model not only structure is simple, easy to operate, and can save change capillary time, improve the production output of lithium battery bag.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: the structural representation of lithium battery bag weld jig as shown in Figure 1, comprise box-type clamp body 1, the inwall matched in clearance of box-type clamp body 1 lower end and insulation tank 3, is also provided with hydraulic mandril 7 at the top of box-type clamp body 1 simultaneously.See Fig. 2, in the both sides of box-type clamp body 1, the spacing of 2cm is provided with 12 capillary locating holes 2, pad 11 one_to_one corresponding on the setting position of capillary locating hole and metal mica sheet 9, the centre of capillary locating hole 2 is provided with capillary dividing plate 8, and the thickness of capillary dividing plate 8 is consistent with breach 10 width of metal mica sheet 9, described capillary dividing plate 8 adopts insulating materials to make.
During welding, first be superimposed and staggered lithium battery and metal mica sheet 9 composition lithium battery bag 6, then lithium battery bag 6 is placed in the insulation tank 3 on butt-welding machine workbench 4, with box-type clamp body 1, lithium battery bag 6 is covered again, and be pressed in box-type clamp body 1 top with hydraulic mandril 7 and be fixed, now adopt a pair capillary 5 through the capillary locating hole 2 on box-type clamp body 1, and control the spacing between two capillaries 5 by the capillary dividing plate 8 in the middle of capillary locating hole 2, then carry out spot welding, metal mica sheet 9 is welded on the two poles of the earth of lithium battery.During welding with one of them capillary locating hole 2 for benchmark, the distance values moving 2cm when having welded a point again welds another point, until welded by pads all on lithium battery bag 6.
