Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
The utility model is a kind of brace of automatic spot tool, and it, according to the arrangement mode of different battery pack structures, battery and connection in series-parallel form etc., through targeted design, is made to measure.This connecting sheet components can meet the requirement of main flow stitch welding machine automatic spot, there will not be again the situation that brace stitch welding, soldering high temperature wire are much mixed and disorderly, simplifies production technology, accomplish that comprehensive materials are economized most simultaneously.
Each brace has splitter box and 18,4 the convex closure 18 one-tenth matrix arrangements of 4 convex closures in the relevant position of each battery end of correspondence, at each 2 convex closures 18 of splitter box bilateral symmetry distribution; In 4 convex closures 18, the central point of diagonal angle convex closure 18 line overlaps with the center of circle of 18650 lithium battery ends, to ensure the situation that there will not be convex closure 18 partially to weld.
When implementing spot welding to battery pack, the splitter box trend of all braces of battery pack homonymy is all in same direction; The splitter box trend of battery pack both sides can be same direction, also can vertical direction each other, and the trend of both sides splitter box also can become arbitrarily angled, and be convenient to realize automatic spot, battery pack automatic spot is shaping; As long as the splitter box of battery pack homonymy brace to move towards direction consistent, battery pack just can an automatic spot shaping.
Each brace has pin to draw, and avoids and carries out soldering in battery core end, reduce the impact on battery performance and useful life while guarantee there will not be nickel sheet stitch welding.
Brace pin needs the both sides, position of bending to be designed with gap, and has a small sircle hole at the end of brace pin, so that soldering high temperature wire.In technique, first at brace end small sircle hole place's soldering high temperature wire, and then along gap bending on pin.If because carry out soldering again after bending, not easy to operate, and easily scald the PVC coating on 18650 battery core surfaces.
Needing the pin carrying out the brace coordinated to pcb board 12 to be directly connected with pcb board 12 soldering through hole corresponding on pcb board 12 after the bending of 2-3 road, reduce the use of higher temperature line, Simplified flowsheet, product is more succinct.
The utility model is useful on main flow stitch welding machine.Main flow stitch welding machine and stitch welding machine have two sources of welding current, and each source of welding current respectively connects two welding rods, symmetrical, lay respectively at the both sides, end of 18650 lithium batteries; During spot welding, the welding rod of both sides discharges simultaneously, two welding rods of homonymy, with the center line of brace splitter box for symmetry axis, symmetrical; Welding rod cross section is rectangle, two convex closures 21 of a welding rod spot welding simultaneously splitter box homonymy.
Because the arrangement mode of battery pack structure, battery and connection in series-parallel form etc. are of a great variety, at this for a kind of connected mode (as Figure 1-Figure 4) of the battery pack of typical 3 string isosceles triangles arrangements in detail, embodiment of the present utility model is described in detail.The brace of a set of automatic spot tool of the battery pack of 3 string isosceles triangle arrangements, comprises the brace of four kinds of specifications: the first brace 1, second brace 2, the 3rd brace 4, the 4th brace 6.
The battery core of 3 string isosceles triangle arrangements is positioned in automatic spot tool, the brace of four specifications is individually fixed on two side shields (i.e. the first tool baffle plate 13, second tool baffle plate 14) of automatic spot tool, namely the first brace 1 and the 3rd brace 4 are fixed on the first tool baffle plate 13, second brace 2 and the 4th brace 6 are fixed on the second tool baffle plate 14, and then close baffle plate.Close after baffle plate, splitter box (i.e. first splitter box 17 of all braces, second splitter box 18,3rd splitter box 19,4th splitter box 20) in the same direction, the end of each 18650 battery cores is to there being four convex closures 21, and the cornerwise mid point of convex closure 21 of each brace is on the center line on the 18650 battery core faces of cylinder.
As shown in Fig. 3-Fig. 7, there is the first pin 9-1 one end of first brace 1, the head of the first pin 9-1 has the first small sircle hole 8-1, the both sides of the first pin 9-1 all have a first gap 10-1, there is the first splitter box 17-1 the centre of first brace 1 other end, and the both sides of the first splitter box 17-1 are evenly distributed with 4 convex closures 18.
The shape of the second brace 2 is " Z " font, and the two ends of the second brace 2 all have a second splitter box 17-2, and there is the second pin 9-2 the inner side that the both sides of each second splitter box 17-2 are evenly distributed with 4 convex closures 18, second brace 2 one end.
The shape of the 3rd brace 4 is native font, 3rd pin 9-3 is arranged at the top of the 3rd brace 4, the both sides of the 3rd pin 9-3 all have a second gap 10-2, the head of the 3rd pin 9-3 has the second small sircle hole 8-2, the two bottom sides of the 3rd brace 4 all has a 3rd splitter box 17-3, and the both sides of each 3rd splitter box 17-3 are evenly distributed with 4 convex closures 18.
The flat shape of the 4th brace 6 is rectangle, and there is the 4th pin 9-4 its one end, and the other end has the 4th splitter box 17-4, and the both sides of the 4th splitter box 17-4 are evenly distributed with 4 convex closures 18.
The automatic spot tool being placed with battery core and brace is put into stitch welding machine, adjust two welding rods at two ends respectively, ensure that the welding rod of homonymy is symmetrically distributed in the both sides of corresponding brace splitter box center line, ensure that two welding rods at two ends are symmetrical, each welding rod can cover two convex closures 21 of splitter box homonymy completely simultaneously.Start-up point unsolder closes, and a quick automatic spot is shaping, both improves welding efficiency, and can ensure welding quality consistency again.
As shown in Figure 8, the battery pack that point welds, three road bendings are had at the pin (the second pin 9-2 and the 4th pin 9-4) of two brace (the second brace 2 and the 4th brace 6) of nearly pcb board 12, the end of pin directly inserts the hole on pcb board 12, coordinates with pcb board 12, carries out soldering connection, both the use of high temperature wire had been reduced, save production cost, in turn simplify production technology, the effect of positioning supports is played in three road bendings of nickel sheet pin simultaneously to pcb board 12.
The battery pack that point welds, first soldering higher temperature line is carried out at circular hole (the first small sircle hole 8-1 and the second small sircle hole 8-2) place of pin (the first pin 9-1 and the 3rd pin 9-3) end of two brace (the first brace 1 and the 3rd brace 4) away from pcb board 12 end, again along gap (the first gap 10-1 and the second gap 10-2) bending to 18650 battery core face of cylinder dociles, the other end of higher temperature line is connected with pcb board 12 and carries out soldering.
