Battery generally comprises electric core, is positioned at baffle and other dependency structure assemblies of electric core front end, for example, and protecgulum, bonnet and shell etc.Fuse generally is installed on the baffle, and when battery temperature was elevated to uniform temperature, fuse broke off, and prevents the blast of battery.Being connected between electricity core and the fuse connects through spot welding realizes.In order to reach the purpose that reduces electric core thickness, generally require aluminium nickel composite band point to be welded on the copper pin of fuse, and the welding pulling force require more than or equal to 10N.
Existing spot welding mode is that fuse and aluminium nickel composite band are placed on the spot welding fixture (SWFX), and wherein, the copper pin of fuse is positioned at aluminium nickel composite band top, the copper pin of mash welder is directly contacted with the copper pin carry out spot welding then.But because the salient point of the copper pin of fuse is upwards to be provided with, and aluminium nickel composite band is again double-decker, so the difficulty of spot welding is bigger; Cause rosin joint or dry joint easily; And pulling force do not reach requirement, therefore occurs a large amount of defective products easily, influences product quality.And rosin joint and dry joint carry out repair welding after needing special personnel to go to pick out again again, wastes time and energy, and influences production capacity.
In addition, increase the relevant parameters such as energy output of spot-welding equipment, though can avoid phenomenons such as dry joint and rosin joint, but bad phenomenon such as weldering, fried fire and burn-through can appear.Wherein, fried fire is especially serious, thereby causes scrapping of fuse, and low, the excellent rate of utilization of materials is low, fried fiery phenomenon takes place cause that sparks flying off in all directions, possibly damage adjacent devices, even injure operating personnel.
In view of this, necessaryly provide a kind of and can avoid rosin joint, dry joint and fried fiery phenomenon, and have the spot-welding technology of higher welding efficiency and the spot welding fixture (SWFX) of use thereof.
Summary of the invention
One of the object of the invention is: to the deficiency of prior art, and a kind of rosin joint, dry joint and fried fiery phenomenon can avoided is provided, and has the spot welding fixture (SWFX) of the spot-welding technology use of higher welding efficiency.
To achieve these goals, the present invention adopts following technical scheme:
A kind of spot welding fixture (SWFX) is provided, comprises jig main body and be located at electric core rest area and the fuse rest area on the said jig main body, be provided with between said electric core rest area and the fuse rest area and keep away a hole.
As a kind of improvement of spot welding fixture (SWFX) of the present invention, said electric core rest area is provided with the fuse rest area is vertical.
As a kind of improvement of spot welding fixture (SWFX) of the present invention, said electric core rest area is a groove structure.
As a kind of improvement of spot welding fixture (SWFX) of the present invention, said fuse rest area is a groove structure.
As a kind of improvement of spot welding fixture (SWFX) of the present invention, also be provided with the adjuster that is used to regulate the capillary height on the said jig main body.
As a kind of improvement of spot welding fixture (SWFX) of the present invention, said electric core is provided with the lug that aluminium nickel composite band is processed.
With respect to prior art, spot welding fixture (SWFX) of the present invention can be good at locating the position of fuse and metal tape, and can adjust the height of capillary, improves point quality, reduces the failure welding rate, boosts productivity, and practices thrift cost.
Another object of the present invention is to provide a kind of spot-welding technology, may further comprise the steps:
The first step, fuse faced up is positioned over the fuse rest area, and electric core is positioned over electric core rest area, guarantees that cell polar ear is positioned at the copper pin top of fuse, and the copper pin of fuse is positioned at and keeps away on the hole;
Second step placed the capillary of mash welder on the lug of electric core, carried out spot weld operation.
As a kind of improvement of spot-welding technology of the present invention, before the spot weld operation, adopt adjuster to regulate the height of welding end pin.
As a kind of improvement of spot-welding technology of the present invention, the lug of said electric core is processed by aluminium nickel composite band.
With respect to prior art, spot-welding technology of the present invention reduces the difficulty of spot welding, and can improve the spot welding pulling force through aluminium nickel composite band being positioned at the copper pin top of fuse, guarantees quality of welding spot, thereby realizes the thickness that electric core is less; And adjuster can be regulated the height of welding end pin, and exports through the energy of control point welding machine, can improve quality of welding spot, avoids phenomenons such as rosin joint, dry joint and fried fire, has improved production efficiency, has reduced cost.Simultaneously, because spot welding is in keeping away a hole, to carry out, the spark that spills in the time of therefore can reducing welding is avoided the injury that other devices and personnel are caused.
Description of drawings
Fig. 1 is the vertical view of spot welding fixture (SWFX) of the present invention;
Fig. 2 is the upward view of spot welding fixture (SWFX) of the present invention.
The specific embodiment
Below in conjunction with embodiment and Figure of description, the present invention is described in further detail, but embodiment of the present invention is not limited thereto.
As illustrated in fig. 1 and 2, spot welding fixture (SWFX) of the present invention comprises jig main body 1 and the electric core rest area 2 and fuse rest area 3 be located on the said jig main body, is provided with between said electric core rest area 2 and the fuse rest area 3 and keeps away a hole 4.Said electric core rest area 2 and the 3 vertical settings of fuse rest area.Said electric core rest area 2 is a groove structure.Said fuse rest area 3 is a groove structure.Said electric core is provided with the lug that aluminium nickel composite band is processed.
