The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The embodiment relates to a flexible circuit board positioning tool, which is used for positioning a nickel sheet 220 on a flexible circuit board 22 on a battery module. The flexible circuit board positioning tool comprises two positioning frames 1 which are hinged together, and the two positioning frames 1 are in a closed state close to each other and in an open state far away from each other due to the fact that the two positioning frames 1 are hinged together.
Specifically, the positioning frame 1 includes a main body having a pressing portion and a nickel plate positioning portion 120, and a clamping leg 10 connecting the main body and extending to one end of the main body. With the switching of the two positioning frames 1 from the folded state to the unfolded state, the clamping support leg 10 can extend into the clamping groove 21 formed on the battery module, so that the pressing portion is pressed on the flexible circuit board 22, and the nickel sheet 220 is positioned on the nickel sheet positioning portion 120.
Like the structure, when two locating racks 1 switch to the expansion state from the state of closing up, joint stabilizer blade 10 can stretch into the draw-in groove 21 on the battery module, supports the portion of pressing and pushes down flexible circuit board 22 and makes flexible circuit board 22 be difficult for removing, and nickel piece location portion 120 can carry out spacing to nickel piece 220 simultaneously, and then guarantees the rigidity of nickel piece 220 in welding process, and can improve the positioning accuracy of nickel piece 220, guarantees welding effect and yields.
Based on the above design concept, an exemplary structure of the flexible circuit board positioning tool of the present embodiment is shown in fig. 1 and fig. 2, it should be noted that the pressing portion includes a pressing plate 11 disposed on the main body, one end of the pressing plate 11 is provided with two positioning support plates 12 arranged at an interval, and a nickel plate positioning portion 120 is defined between the two positioning support plates 12.
Because the flexible circuit board 22 in this embodiment needs to be limited to ensure the position of the flexible circuit board 22 to be fixed in the welding process, when the two positioning frames 1 enter the unfolding state from the folding state, the pressing plate 11 can press the flexible circuit board 22, and meanwhile, the nickel sheet 220 on the flexible circuit board 22 is also limited by the nickel sheet positioning part 120, so that the flexible circuit board 22 and the nickel sheet 220 are not easy to move in the welding process, and the welding effect can be ensured. It is worth mentioning that the width of the nickel plate positioning portion 120 matches the width of the nickel plate 220, so as to prevent the nickel plate 220 from swaying in the nickel plate positioning portion 120.
As shown in fig. 1, the clamping leg 10 is connected to a positioning strip 12 and extends towards an end remote from the pressing plate 11. The clamping support legs 10 can extend into the clamping grooves 21 in the battery module, each positioning frame 1 is provided with the clamping support legs 10, the clamping support legs 10 in the two positioning frames 1 are not located on the same straight line, namely the clamping support legs 10 in the two positioning frames 1 are arranged in a staggered mode, and therefore the clamping support legs 10 in the two positioning frames 1 extend into the clamping grooves 21 in the battery module, so that the positioning tool can be fixed, and the nickel sheet 220 can be welded subsequently.
In addition, in order to improve the stability of the positioning tool, the clamping support leg 10 is arranged corresponding to the positioning support plate 12. It can be understood that the number of clamping support legs 10 is 4, and the distance between two clamping support legs 10 matches the width of two clamping grooves 21 on the same side of the battery module, so that the positioning frame 1 is not easy to move.
In order to facilitate the processing and manufacturing of the positioning tool, the clamping support leg 10, the positioning support plate 12 and the pressing plate body 11 are integrally formed. In addition, the positioning frame 1 is made of an insulating material, for example, a resin material or a nylon material, so as to prevent the flexible circuit board 22 and the nickel plate 220 from being affected during the soldering process.
In this embodiment, in order to improve production efficiency, the tip of main part is equipped with hinge hole 13, and two locating racks 1 are through wearing to locate the articulated connection of connecting piece 130 in hinge hole 13. The connecting member 130 may be a rotating shaft or a pin. The locating rack 1 is hinged through the connecting piece 130 penetrating through the hinge hole 13, so that the two locating racks 1 can rotate relative to the connecting piece 130 conveniently, and the locating tool can be quickly disassembled and assembled through pressing and lifting actions, and is simple in overall structure, simple and convenient to operate and quick.
As shown in fig. 2 and 3, the battery module has a plurality of unit cells 2 stacked together, and the positive and negative poles of adjacent unit cells 2 are connected in series by a bus bar 20, so that a clamping groove 21 is formed between the bus bar 20 and the upper end surface of the unit cell 2. Wherein, the busbar 20 welds between the positive post and the negative pole post of monomer electricity core 2, so busbar 20 is located positive post and negative pole post surface, and the width of busbar 20 is greater than positive post and negative pole post, therefore can make and form draw-in groove 21 between busbar 20 and the electric core up end, joint stabilizer blade 10 just can stretch into in the draw-in groove 21 fixed.
In order to improve the use efficiency of the positioning tool, a rotation limiting part 14 is arranged on one positioning frame 1, and the rotation limiting part 14 is used for limiting the relative rotation angle of the two positioning frames 1. Specifically, the rotation limiting portion 14 includes a limiting protrusion disposed at one end of the positioning frame 1 near the hinge joint. Because of rotating spacing portion 14 and can restricting the relative pivoted angle of two locating racks 1, consequently when two locating racks 1 are in the state of foling, there is the distance between the joint stabilizer blade 10 on two locating racks 1, so can make two locating racks 1 enter into the state of expanding more fast when using this frock to can improve the availability factor of location frock, and help welding work efficiency's improvement.
This embodiment flexible circuit board location frock, support the clamp plate body 11 and nickel piece location portion 120 through locating rack 1 on can carry out multi-direction spacing to nickel piece 220, and then guarantee the rigidity of nickel piece 220 in welding process, in addition, locating rack 1 avoids utilizing flexible circuit board 22 peripheral space, do the location with the inside monomer electric core 2 utmost point posts of battery module, can reduce the space demand, reduce the outside space restriction to module and frock, can realize quick assembly disassembly and then promote production efficiency.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
