Description

Technical Field

[0001] This utility model relates to the field of lithium battery packaging technology, specifically a polymer soft-pack lithium battery packaging fixing fixture. Background Technology

[0002] Polymer soft-pack lithium batteries are widely used in electronic devices, new energy vehicles and other fields due to their advantages such as high energy density, good safety performance and customizable shape. In their production process, packaging fixtures are key equipment to ensure the accuracy and quality of battery assembly and improve production efficiency.

[0003] Utility model patent CN222725840U discloses a lithium battery packaging fixture, which includes a jig and a base. The jig is composed of two side plates spliced ​​together, and each side plate has multiple spaced positioning grooves. Two positioning grooves form a battery slot. The base is located above and below the jig, and the base has a contouring groove for positioning and mounting welded components. In practical design, the battery is placed in the positioning groove of one side plate, and then the other side plate is spliced ​​together, so that the two positioning grooves form the battery slot. The base is then installed at the upper and lower ends of the jig, respectively, thus achieving the initial positioning of the lithium battery. At the same time, welding rods or welding sheets are placed directly in the contouring groove and then welded to the electrode sheets of the lithium battery to complete the assembly of the battery pack, i.e., the packaging of the battery pack. The fixture can then be directly fixed to the intended product. The fixture can also be additionally equipped with a heat dissipation structure, a protective structure, or a PCB board to improve the safety of the battery pack.

[0004] The fixed battery slot and positioning structure of the current lithium battery packaging fixture make it difficult to adapt to the packaging and positioning requirements of cuboid battery packs composed of different numbers of cylindrical soft-pack lithium batteries. When the specifications of the packaged battery pack change, different fixtures need to be replaced, which is inconvenient and costly. In view of this, we propose a polymer soft-pack lithium battery packaging fixing fixture. Utility Model Content

[0005] The purpose of this invention is to provide a polymer soft-pack lithium battery packaging and fixing fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polymer soft-pack lithium battery packaging and fixing fixture, comprising:

[0008] The base is used to support multiple cylindrical soft-pack lithium batteries arranged in a row. Side plates are provided on the rear and right edges of the top surface of the base. Guide posts are provided on the outer side of the side plates, and abutment springs are sleeved on the outer side of the guide posts.

[0009] A longitudinal abutment is used to limit the left end of multiple arranged cylindrical soft-pack lithium batteries. The first end of the longitudinal abutment is slidably connected to the side plate located on the rear side. The abutment spring on the side plate located on the rear side abuts against the left end face of the longitudinal abutment. A sleeve cavity is opened in the middle of the longitudinal abutment.

[0010] A transverse abutment is used to limit the front end of multiple arranged cylindrical soft-pack lithium batteries. The first end of the transverse abutment is slidably connected to the side plate located on the right side. The abutment spring located on the side plate on the right side abuts against the rear end face of the transverse abutment. A baffle is provided in the middle of the transverse abutment, and the baffle passes through the cavity.

[0011] The two side plates, the longitudinal abutment, and the transverse abutment form a rectangular space to clamp the arranged cylindrical soft-pack lithium batteries.

[0012] Preferably, a guide groove is provided at the middle position of the side plate, and a pair of sliding strips are provided at the first end of both the longitudinal abutment plate and the transverse abutment plate. The sliding strips extend into the guide groove and are slidably connected to the side plate.

[0013] In this configuration, the guide groove works in conjunction with the sliding bar to provide precise guidance for the sliding of the longitudinal and transverse abutments, ensuring smooth sliding of the abutments and preventing deviation.

[0014] Preferably, a partition strip is provided at both the top and bottom edges of the right end face of the longitudinal abutment, and a partition piece is provided on the rear end face of the transverse abutment. The surfaces of the partition strip and the partition piece are provided with grooves that are adapted to the outline of the cylindrical soft-pack lithium battery.

[0015] In this configuration, the grooves on the separator strips and separator plates conform to the shape of the lithium battery, achieving precise positioning and separation of the lithium battery and preventing the battery from being misaligned or squeezed during clamping.

[0016] Preferably, a pair of protrusions are fixed on the outer end face of the side plate, and the guide post is fixed between the two protrusions. The two guide posts on the two side plates respectively penetrate the longitudinal abutment and the transverse abutment.

[0017] In this configuration, the boss provides stable support for the guide post, which penetrates the abutment plate, providing a stable guiding foundation for the sliding of the abutment plate and enhancing structural stability.

[0018] Preferably, a lever is provided at the first end of both the longitudinal abutment and the transverse abutment;

[0019] In this setting, the lever makes it easier for the operator to apply force, making the operation of moving the longitudinal and lateral abutments more convenient and effortless.

[0020] Preferably, the base has a side groove at its left end and front edge, and the ends of the longitudinal abutment plate and the transverse abutment plate are provided with end seats. The bottom end of the end seat is rotatably connected to a roller, the roller is located in the side groove, and the roller abuts against the groove wall of the side groove.

[0021] In this setting, the rollers work in conjunction with the side grooves to reduce friction when the longitudinal and transverse abutments slide, making the abutment movement smoother.

[0022] Preferably, a T-shaped sliding groove is provided at the top position of the left end face of the longitudinal abutment plate, and a locking assembly is slidably connected in the sliding groove. The locking assembly includes a sliding seat that moves along the sliding groove and a stop bolt threaded to the end of the sliding seat.

[0023] Preferably, a stop strip is embedded at the top of the baffle. When the end of the stop bolt abuts against the stop strip, the relative position of the longitudinal abutment and the transverse abutment is locked by the locking assembly.

[0024] In these two settings, the T-shaped sliding groove provides installation and movement space for the locking component, ensuring stable sliding of the sliding seat and facilitating subsequent position locking operations. The stop strip and stop bolt cooperate to restrict the relative movement of the stop plate by pressing against it, ensuring that the lithium battery is fixed in position when clamped and preventing the stop plate from sliding accidentally.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This polymer soft-pack lithium battery encapsulation and fixing fixture, through the cooperation of a base, a longitudinal abutment plate, a transverse abutment plate, and a side plate, allows the longitudinal and transverse abutments to slide on the side plate. Under the elastic force provided by the abutment spring, the longitudinal and transverse abutments can hold a cuboid battery pack composed of multiple cylindrical soft-pack lithium batteries against the two side plates, thus achieving the purpose of clamping a cuboid battery pack formed by multiple cylindrical soft-pack lithium batteries. By flexibly adjusting the size of the rectangular clamping space, the fixture can clamp cuboid battery packs composed of different numbers of cylindrical soft-pack lithium batteries without having to change the fixture for different numbers of battery packs, improving the versatility and ease of use of the fixture.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] Please see Figures 1-4 A polymer soft-pack lithium battery packaging and fixing fixture includes a base 100 for assembling a plurality of cylindrical soft-pack lithium batteries 200 arranged in a row, a longitudinal abutment 300 for limiting the left end of the plurality of cylindrical soft-pack lithium batteries 200 arranged in a row, and a transverse abutment 400 for limiting the front end of the plurality of cylindrical soft-pack lithium batteries 200 arranged in a row. Side plates 110 are provided at the rear side and right side edge of the top surface of the base 100. The two side plates 110, the longitudinal abutment 300 and the transverse abutment 400 form a rectangular space to clamp the plurality of cylindrical soft-pack lithium batteries 200 arranged in a row.

[0041] like Figure 2As shown, in this utility model, a guide post 120 is provided on the outer side of the side plate 110, and an abutment spring 121 is sleeved on the outer side of the guide post 120. A pair of protrusions 112 are fixed on the outer end face of the side plate 110, and the guide post 120 is fixed between the two protrusions 112. The two guide posts 120 on the two side plates 110 respectively pass through the longitudinal abutment plate 300 and the transverse abutment plate 400. The protrusions 112 are used to fix the guide post 120, and the guide post 120 provides guidance for the movement of the longitudinal abutment plate 300 and the transverse abutment plate 400. The abutment spring 121 on the rear side plate 110 abuts against the left end face of the longitudinal abutment plate 300, and the abutment spring 121 on the right side plate 110 abuts against the rear end face of the transverse abutment plate 400. The abutment spring 121 provides a clamping force for the longitudinal abutment plate 300 and the transverse abutment plate 400, so that they can fit tightly against the lithium battery and ensure the clamping effect.

[0042] like Figures 1-4 As shown, specifically, a guide groove 111 is provided at the middle position of the side plate 110. A pair of sliding strips 330 are provided at the first end of both the longitudinal abutment plate 300 and the transverse abutment plate 400. The sliding strips 330 extend into the guide groove 111 and are slidably connected to the side plate 110. Under the action of the sliding strips 330 and the guide groove 111, the first end of the longitudinal abutment plate 300 is slidably connected to the side plate 110 located on the rear side, and the first end of the transverse abutment plate 400 is slidably connected to the side plate 110 located on the right side. The guide groove 111 and the sliding strips 330 cooperate with each other to further enhance the stability and guidance of the longitudinal abutment plate 300 and the transverse abutment plate 400 when sliding, and prevent them from deviating during movement.

[0043] like Figure 3 and Figure 4 As shown, furthermore, a lever 340 is provided at the beginning position of both the longitudinal abutment 300 and the transverse abutment 400. The lever 340 is provided to facilitate the operator to move the longitudinal abutment 300 and the transverse abutment 400, making the operation more convenient.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, in addition, a cavity 310 is provided in the middle of the longitudinal abutment 300, and a baffle 410 is provided in the middle of the transverse abutment 400. The baffle 410 passes through the cavity 310. The cooperation between the cavity 310 and the baffle 410 enables the longitudinal abutment 300 and the transverse abutment 400 to restrain each other during movement, ensuring the coordination of their movement, and also enhancing the structural stability of the rectangular clamping space.

[0045] like Figures 1-4As shown, it is worth noting that a partition strip 320 is provided at the top and bottom edges of the right end face of the longitudinal support plate 300, and a partition piece 420 is provided on the rear end face of the transverse support plate 400. The surfaces of the partition strip 320 and the partition piece 420 are provided with grooves that are adapted to the outline of the cylindrical soft-pack lithium battery 200. The grooves on the partition strip 320 and the partition piece 420 are adapted to the shape of the cylindrical soft-pack lithium battery 200, which can more accurately position and separate the lithium battery and prevent the lithium battery from being misaligned or squeezed against each other during the clamping process.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the left end and front edge of the base 100 are provided with side grooves 130, and the ends of the longitudinal abutment plate 300 and the transverse abutment plate 400 are provided with end seats 350. The bottom end of the end seat 350 is rotatably connected to a roller 351. The roller 351 is located in the side groove 130 and abuts against the groove wall of the side groove 130. The combination of the side groove 130, the end seat 350 and the roller 351 can assist the longitudinal abutment plate 300 and the transverse abutment plate 400 to slide, reduce the friction between them and the base 100, and make the abutment plate move more smoothly.

[0047] In use, the polymer soft-pack lithium battery packaging and fixing fixture of this embodiment is first used by moving the levers 340 on the longitudinal abutment 300 and the transverse abutment 400 outwards, causing the longitudinal abutment 300 and the transverse abutment 400 to slide outwards on the two side plates 110 respectively and compress the corresponding abutment springs 121. At this time, the longitudinal abutment 300 and the transverse abutment 400 form a space on the base 100 sufficient to place the cylindrical soft-pack lithium battery 200. Then, multiple cylindrical soft-pack lithium batteries 200 are placed on the base 100 in a predetermined arrangement. Finally, the levers are released. When the lever 340 is turned, under the elastic force of the abutment spring 121, the longitudinal abutment 300 and the transverse abutment 400 slide along the guide groove 111 on the side plate 110 toward the cylindrical soft-pack lithium battery 200 and finally fit with the multiple combined cylindrical soft-pack lithium batteries 200, so as to achieve the purpose of clamping the battery pack formed by multiple cylindrical soft-pack lithium batteries 200. Moreover, the partition strip 320 on the longitudinal abutment 300 and the partition piece 420 groove on the transverse abutment 400 are adapted to the outer contour of the lithium battery, so as to achieve precise and stable clamping of the lithium battery.

[0048] Example 2

[0049] In order to ensure that the longitudinal abutment 300 and the transverse abutment 400 can move smoothly along the guide post 120 when the longitudinal abutment 300 and the transverse abutment 400 are moved, such as Figure 1 and Figure 5As shown, a sliding groove 360 ​​with a T-shaped cross-section is provided at the top position of the left end face of the longitudinal abutment plate 300, and a locking component 500 is slidably connected in the sliding groove 360.

[0050] Specifically, the locking assembly 500 includes a sliding seat 510 that moves along the sliding groove 360 ​​and a stop bolt 520 that is threaded to the end of the sliding seat 510. The sliding seat 510 has a T-shaped cross-section at its head end, which extends into the sliding groove 360. The T-shaped sliding groove 360 ​​provides installation space and a sliding track for the locking assembly 500, ensuring that the sliding seat 510 can move stably in the groove. The threaded connection between the stop bolt 520 and the sliding seat 510 can be adjusted by rotating the stop bolt 520 to adjust the length of the stop bolt 520. A stop strip 411 is embedded at the top of the baffle 410. When the stop bolt 520 is rotated so that the end of the stop bolt 520 abuts against the stop strip 411, the relative position of the longitudinal stop plate 300 and the transverse stop plate 400 is locked by the locking component 500, thereby restricting the movement of the longitudinal stop plate 300 and the transverse stop plate 400, ensuring that the lithium battery is firmly fixed during the packaging process, and avoiding the packaging operation from being affected by the accidental sliding of the stop plate.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
