Description

Technical Field

[0001] The utility model relates to the field of cylindrical lithium battery processing, in particular to a lithium battery packaging fixture. Background Art

[0002] In the processing of cylindrical lithium batteries (such as packaging structures), the tabs need to be positioned before welding. Existing designs generally install them on a fixture, shape them, and then weld them. Existing fixtures generally use a profiling structure (for example, customer requirements require a long strip of six or four lithium batteries fixed to each other), but the existing fixture structure is relatively complex. The lithium battery is first positioned, and then the adjacent lithium batteries are welded through wires or copper plates to achieve a preliminary battery pack structure. With the increase in customer demand, the existing battery packs have the problem of inconsistent standards, which affects the standardization of inspections. Utility Model Content

[0004] To achieve the above purpose, the utility model provides a lithium battery packaging fixture, comprising:

[0005] A fixture, wherein the fixture is formed by splicing two side plates, the side plates are provided with a plurality of positioning grooves arranged at intervals, and the two positioning grooves surround a battery slot;

[0006] The seat body is arranged at the upper position and the lower position of the fixture, and the seat body is provided with a profiling groove, and the profiling groove is used for the installation and positioning of the welding part.

[0007] In the actual design, the battery is placed in the positioning groove of one of the side panels, and then the other side panel is spliced ​​so that the two positioning grooves surround the battery groove, and then the seat is respectively installed on the upper and lower ends of the fixture, thereby realizing the preliminary positioning of the lithium battery. At the same time, the welding rod or welding sheet is directly placed in the imitation groove, and then welded to the pole piece of the lithium battery to complete the assembly of the battery pack, that is, the packaging of the battery pack is completed, and the fixture can be directly fixed to the predetermined product. The fixture can also be provided with a heat dissipation structure or a protection structure or a PCB board to improve the safety of the battery pack.

[0008] The design is quite ingenious and can be used as both a jig and a shell for battery packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0015] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0016] like Figures 1 to 3 As shown, a lithium battery packaging fixture comprises:

[0017] A fixture 1, wherein the fixture 1 is formed by splicing two side plates, the side plates are provided with a plurality of positioning grooves 11 arranged at intervals, and the two positioning grooves 11 surround a battery slot 10;

[0018] The seat body 2 is arranged at the upper position and the lower position of the fixture 1. The seat body 2 is provided with a profiling groove 21, and the profiling groove 21 is used for installation and positioning of the welding part.

[0019] In the actual design, the battery is placed in the positioning groove 11 of one of the side panels, and then the other side panel is spliced ​​so that the two positioning grooves 11 surround the battery slot 10, and then the seat 2 is respectively installed on the upper and lower ends of the fixture 1, thereby realizing the preliminary positioning of the lithium battery. At the same time, the welding rod or welding sheet is directly placed in the imitation groove 21, and then welded to the pole piece of the lithium battery to complete the assembly of the battery pack, that is, the packaging of the battery pack is completed, and the fixture can be directly fixed to the predetermined product. The fixture can also be provided with a heat dissipation structure or a protective structure or a PCB board to improve the safety of the battery pack.

[0020] This design is quite ingenious and can be used as both a fixture 1 and a shell for battery packaging.

[0021] Specifically, the two sides of the side plate are provided with limiting protrusions 31 and limiting grooves. When the two side plates are spliced ​​together, the limiting protrusions 31 and limiting grooves 32 of the two side plates cooperate with each other, thereby realizing the mutual engagement and limiting of the clamps.

[0022] In the embodiment of the utility model, magnetic parts 4 are further provided on both sides of the side panels, and the two side panels are spliced ​​together to achieve mutual attraction between the side panels.

[0023] Furthermore, a seat body 2 is provided on the upper or lower side of the side plate, and the seat body 2 is integrally formed with the side plate or can be detachably installed. Preferably, the seat body 2 is integrally formed, for example Figure 3 As shown, the assembly steps can be reduced and the splicing of the packaging fixture can be completed in one step.

[0024] Furthermore, the side panels and the seat body 2 are L-shaped.

[0025] In the embodiment of the utility model, a side wing 5 extending outward is provided on the side of the side plate away from the seat body 2, thereby limiting the position of the other side plate and making the engagement more stable.

[0026] Specifically, a recessed positioning hole 6 is provided on the outer side of the seat body 2 , and the positioning hole is adapted to the shape of the lithium battery, so as to limit the two ends of the lithium battery 100 .

[0027] In the embodiment of the utility model, the side plate and the seat body 2 are plastic injection molded. When the side plate and the seat body 2 are integrated, the assembly is simpler, and when they are produced separately, the production cost and defect rate are lower.

[0028] The positioning groove is semicircular.

[0029] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
