Abstract
The utility model relates to the manufacturing field of lithium ion batteries, in particular to an auxiliary welding device for battery packs, which is characterized by comprising a cell stacking board, a front retaining board and a rear retaining board. The front retaining board and the rear retaining board are fixed at the front end and the rear end of the cell stacking board so as to form a cell stacking area, nickel strip holding boards are respectively hinged on the left side and the right side of the cell stacking board, and a plurality of through holes and nickel strip locating grooves are arranged on each of the nickel strip holding boards. The auxiliary welding device has the advantages simplicity, practicability and convenience in operation. When in use, nickel strips can be directly placed in the nickel strip locating grooves, and face the cell directly after the nickel strip holding boards are combined, so that welding is accurate, labor intensity of workers is reduced greatly, and welding quality is improved.
Description
Technical field
The utility model relates to lithium ion battery and makes the field, relates in particular to the auxiliary welder of a kind of battery pack.
Background technology
A kind of electrokinetic cell needs tens round electric cores to carry out forming battery pack up to specification after the connection in series-parallel, through resistance welder nickel strap is welded with the both positive and negative polarity of electric core respectively.Because the quantity of round electric core is more, adopt when putting nickel strap by hand, there have deviation will cause nickel strap and electric core to weld slightly to be insecure, has tangible short circuit hidden danger.Very easily cause short circuit under the long-time situation, and then damage battery pack; In addition, adopt the manual nickel strap speed of directly putting slower, be not easy to the production of scale property.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of battery pack to assist welder, and instead of manual is nickel strap fixedly, avoids damaging battery pack because of short circuit.
The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of battery pack is assisted welder; It is characterized in that: comprise that electric core stacks plate and forward and backward baffle plate; Said forward and backward baffle plate is fixed on electric core and stacks the plate rear and front end and constitute electric core and stack the zone, and the left and right sides that said electric core stacks plate is hinged with the nickel strap placing plate, and said nickel strap placing plate is provided with several through holes and nickel strap locating slot.
Be embedded with magnet between the said adjacent through-holes.
Said lead to the hole site is corresponding with the both positive and negative polarity position that stacks the electric core in back respectively.
Beneficial effect: the utility model is simple and practical, simple operation.During use, directly nickel strap is positioned in the nickel strap locating slot, fastens the nickel strap placing plate, nickel strap is directly aimed at electric core, and welding has accurately reduced working strength of workers greatly, has improved welding quality.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the working state figure of the utility model.
The specific embodiment
The specific embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.As shown in the figure, a kind of battery pack is assisted welder, comprises by electric core stacking plate 1 and forward and backward baffle plate 2,3, and said forward and backward baffle plate is fixed on electric core and stacks the electric core that the plate two ends enough become and stack the zone, in order to stack electric core.The both sides that said electric core stacks plate are hinged with 4, two nickel strap placing plates of nickel strap placing plate and fasten and can electric core be fixed on electric core and stack in the zone.In order to place erose nickel strap, said nickel strap placing plate is provided with several through holes 5 and nickel strap locating slot 6.See through through hole and can see electric core, the nickel strap standing groove is used to place nickel strap 7.Be embedded with magnet 8 between said adjacent through hole, be used for nickel strap is adsorbed onto the nickel strap standing groove.Said lead to the hole site with stack after the both positive and negative polarity position of electric core to corresponding.18650 electric cores with 26 pitch circle type 3.7V are example, and a Battery pack is the voltage about 7.5V if desired, just need the battery of 26 joint 3.7V be divided into two groups of parallel connection back series connection earlier.At this moment, the nickel strap locating slot on nickel strap placing plate is opened between adjacent through hole, is connected to each other, and can the erose nickel strap of a row be placed in the nickel strap locating slot; And the nickel strap locating slot on the nickel strap placing plate of another side is also opened between adjacent through hole, but is divided into two parts, and this two-part nickel strap does not communicate, and can the erose nickel strap of two rows be placed in the nickel strap locating slot.Earlier the electric core electric core that is added to is stacked on the plate during use, directly nickel strap is positioned in the nickel strap locating slot, fasten the nickel strap placing plate, nickel strap is directly aimed at electric core, and welding has accurately reduced working strength of workers greatly, has improved welding quality.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (3)
1. a battery pack is assisted welder; It is characterized in that: comprise that electric core stacks plate and forward and backward baffle plate; Said forward and backward baffle plate is fixed on electric core and stacks the plate rear and front end and constitute electric core and stack the zone; The left and right sides that said electric core stacks plate is hinged with the nickel strap placing plate, and said nickel strap placing plate is provided with several through holes and nickel strap locating slot.
2. battery pack according to claim 1 is assisted welder, it is characterized in that: be embedded with magnet between said adjacent through hole.
