As shown in Fig. 2 a preferred embodiment of the present utility model provides a kind of fixture for laser welding, including for accommodating electricity
Pond group conflux portion 100 pallet 200 and for fixed tray 200 positioner 300.Positioner 300 include base 310,
Pressing plate 320 and power part 330, power part 330 connect base 310 and pressing plate 320, and control pressing plate 320 to move up and down.Pallet
200 are located between base 310 and pressing plate 320, and are detachably mounted on base 310, power part 330 control pressing plate 320 to
Lower movement, and compress the upper surface that pallet 200 is placed with the portion of confluxing 100, pressing plate 320 is further opened with some for laser welding
First through hole 321.So can by the portion of confluxing 100 being positioned on pallet 200 tightly, then pass through first through hole with laser
321 pairs of portions 100 of confluxing weld, and improve quality and the welding efficiency of welding, greatly improve the production effect of power battery pack
Rate.In the present embodiment, portion 100 of confluxing includes copper bar 110 and conducting strip 120, and conducting strip 120 is nickel sheet.Power part 330 is gas
Cylinder, and be fixed on base 310 naturally it is also possible to be fixed on pressing plate 320.The aperture upper surface of first through hole 321 expands shape
Become irregular concavity, be so avoided that first through hole 321 with laser beam interference therein it is ensured that the reliability of laser welding.
As shown in figure 3, being installed with least two first limiting sections 311 on base 310, it is spacing that pallet 200 is fastened on first
Between portion 311.The inner side of one of them the first limiting section 311 is additionally provided with the elastic portion 312 of protrusion.When pallet 200 snaps in
When between one limiting section 311, pallet 200 extrudes elastic portion 312 and produces the power mutually extruding, and so energy can utility tray
Positioning, pallet 200 can be avoided stuck again.For further location tray 200, bottom 310 is fixedly provided with the second limiting section
313, the second limiting section 313 supports the bottom side of pallet 200.In the present embodiment, base 310 is made up of Steel material.
As shown in Figs. 4-6, pallet 200 offers at least one for first groove 210, some of positioning copper strips 110
For positioning the second groove 220 of conducting strip 120 and the 3rd groove 230 of copper bar 110 of conveniently taking.Between the second groove 220
Every the both sides being distributed in the first groove 210 length direction, the first groove 210 is connected with one end of the second groove 220, the 3rd groove
230 are connected with one end of the first groove 210.The second groove 220 in the first groove 210 side is another with the first groove 210
Second groove 220 of side staggers setting, and when so adapting to install battery pack, positive and negative electrode confluxes the cooperating of portion.First is recessed
Groove 210 bottom is provided with the first elastic component 211 of protrusion.In the present embodiment, the first groove 210 has four, so can improve
Production efficiency.First elastic component 211 is spring-loaded plunger, certainly can also be other elastic components, such as shell fragment etc..First elastic component
211 have multiple, are separately positioned on the position near every one second groove 220 for the first groove 210 bottom.In welding process, profit
Hold out against the welding position of copper bar 110 and conducting strip 120 with the first elastic component 211 intrinsic elasticity power, eliminate or reduce welding position
Gap, improves stability and the yield of welding.In addition, pallet 200 is imitated structure, copper bar 110 and conduction can be welded according to need
The shape of piece 120, to make the shape of the first groove 210 and the second groove 220, so enables positive pole copper bar and negative pole copper bar
Welding with conducting strip 120.
Because conducting strip 120 is relatively more frivolous, in order to be able to effective positioning conducting strip 120, the second groove 220 bottom is installed with use
The first magnet 221 in absorption conducting strip 120.Such second groove 220 can also position other can leading by the first magnet adsorption
Electric piece 120, such as iron plate etc..In the present embodiment, pallet 200 also includes the 4th groove 240 of conducting strip 120 of conveniently taking,
4th groove 240 is connected away from one end of the first groove 210 with the second groove 220.In addition, being further opened with first on pallet 200
The edge of through hole 250, the inwall of first through hole 250 and pallet 200 forms the handle for lifting, so can be easy to pallet 200
Snap in base 310 or pull out from base 310.The bottom side of pallet 200 is installed with the second magnet 260, and pallet 200 passes through the second magnetic
Iron 260 adsorbs on the second limiting section 313.
The following is the using method of the utility model fixture for laser welding: first it would be desirable to welding copper bar 110 puts into first
In groove 210, the first elastic component 211 has certain resilient support to copper bar 110；Then, conducting strip 120 is put into second recessed
In groove 220, and positioning is adsorbed by the first magnet 221；Again pallet 200 is snapped in base 310, and pass through the first limiting section 311 He
Second 313 points of limiting section position；Finally, control pressing plate 320 to move down by power part 330, and compress pallet 200 and be placed with remittance
The upper surface in stream portion 100, but because copper bar 110 has the support of the first elastic component 211 below so that copper bar 110 and conducting strip 120
Be in close contact, by first through hole 321, copper bar 110 and conducting strip 120 welded with laser, improve the quality of welding with
Welding efficiency, greatly improves the production efficiency of power battery pack.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in the utility model
Protection domain within.
