Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the present invention limit the scope of the invention.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 show a specific embodiment of this battery pack signal sampling of the present invention sheet, this sampling sheet is for connecting battery pack 1 and pcb board 2, thus by Signal transmissions such as the voltage of battery pack 1, electric current and temperature to pcb board 2, with the coherent signal such as voltage, temperature allowing described pcb board 2 gather described battery pack 1.
Wherein, battery pack 1 comprises fixture 11 with battery settling hole 11a and the cell 12 that is plugged in battery settling hole 11a.General a set of battery pack has multiple fixture 11, is provided with multiple battery settling hole 11a in each fixture 11, is all inserted with battery cell, as Fig. 3 in each battery settling hole 11a.For the ease of Automated assembly, pcb board 2 described in this example adopts hard pcb board, it welding jack comprising plate body, be located at the signals collecting line on this plate body and offer on this plate body.
The key of the present embodiment changes key and is, described sampling sheet 3 comprises battery connection part 31 and pcb board connecting portion 32.Described battery connection part 31 is arranged in described battery settling hole 11a, and is connected with the cell 12 in this battery settling hole 11a.Described pcb board connecting portion 32 stretches out outside described battery settling hole 1a, and be positioned at the exterior rim place of described fixture 11, and pcb board connecting portion 32 is provided with solder-bump 32a, described solder-bump 32a stretches in described welding jack, and with weld jack and be welded and fixed.And the signals collecting line on solder-bump 32a and pcb board 2 is electrically connected.
Refer again to Fig. 2, Fig. 3 and Fig. 4, now the assembly method of this for the present embodiment sampling sheet is described below: before battery pack 1 self completes assembling, in advance sampling sheet 3 is arranged in fixture 11, and make the pcb board connecting portion 32 of sampling sheet 3 be in the exterior rim place of fixture 11, allow pcb board connecting portion 32 place of these sampling sheets 3 (locate to carry out welding with pcb board 2) point-blank simultaneously, then pcb board 2 is lain in above battery pack 1, and make the solder-bump 32a on the welding jack aligning sampling sheet 3 on pcb board 2, under the Action of Gravity Field of pcb board 2, solder-bump 32a on each sampling sheet 3 stretches in each welding jack of pcb board 2 respectively, laser welding head 4 is adopted to be welded together with the jack that welds of pcb board 2 by solder-bump 32a afterwards, thus complete the connection of sampling sheet 3 pairs of battery pack 1 and pcb board 2.
In order to ensure the assembling evenness of pcb board 2 in battery pack 1, make the solder-bump 32a on each sampling sheet 3 be stretches in the welding jack of pcb board 2 simultaneously accordingly, to guarantee that each sampling sheet 3 welds with the reliable of pcb board 2, this example described pcb board connecting portion 32 is adopted have deformability elastomeric element---sampling sheet 3 is for having the metal material of elastic deformability.As shown in Figure 3, after each sampling sheet 3 is arranged in battery pack 1, assembly crewman can not ensure that the height of pcb board connecting portion 32 on each sampling sheet 3 is completely concordant, because in this example, pcb board connecting portion 32 has the deformability of above-below direction, after pcb board 2 is placed in battery pack 1, those pcb board connecting portions 32 with high height can because be subject to compressing and being out of shape of pcb board 2 downwards, thus ensure that the assembling evenness of pcb board 2 in battery pack 1, make the solder-bump 32a on each sampling sheet 3 be stretches in the welding jack of pcb board 2 simultaneously accordingly, to guarantee that each sampling sheet 3 welds with the reliable of pcb board 2.
In this example, described solder-bump 32a punching on described pcb board connecting portion 32 forms.
