Description
Technical Field
[0001] This utility model relates to the field of battery pack shaping technology, and more specifically, to a battery pack shaping fixture. Background Technology
[0002] During the manufacturing process of battery packs, nickel plates are typically welded to the ends of the battery pack to ensure effective connection between the battery pack and external circuits or devices. However, newly manufactured battery packs often encounter the problem of the nickel plates not adhering tightly to the battery body. This not only affects the electrical connection performance of the battery pack but may also pose a potential threat to the safety and lifespan of the battery pack.
[0003] To solve this problem, the ends of the battery pack need to be shaped. Traditional battery pack shaping methods mostly rely on manual operation, which is not only inefficient but also makes it difficult to guarantee shaping accuracy and achieve consistent shaping results. Utility Model Content
[0004] The purpose of this invention is to provide a battery pack shaping fixture that greatly improves shaping accuracy and efficiency compared to traditional manual operation.
[0005] A battery pack shaping fixture includes a base, a support seat mounted on the base, a positioning cover plate mounted on the base and adjacent to the support seat, and a drive unit mounted on the base and located on one side of the support seat. The support seat has a groove for accommodating at least one set of battery packs to be shaped. The positioning cover plate is rotatable relative to the support seat to press the battery packs to be shaped into the groove. The groove has an opening on the side near the drive unit. The output end of the drive unit is connected to a shaping plate. The drive unit is used to drive the shaping plate to move horizontally so that the shaping plate moves closer to or away from the opening.
[0006] In the above technical solution, a groove is set on the support base, the battery pack to be shaped is placed in the groove, and then the positioning cover is flipped so that the positioning cover presses against the battery pack to be shaped, thus achieving a stable limiting effect on the battery pack to be shaped. At this time, the drive unit is activated, and the drive unit drives the shaping plate to move horizontally. When the shaping plate approaches the opening, the shaping plate abuts against one end face of the battery pack to be shaped. The drive unit provides a squeezing force on the shaping plate towards the side of the battery pack to be shaped, thereby achieving a shaping effect on the end of the battery pack to be shaped, ensuring that the nickel sheet at the end of the battery pack to be shaped is tightly attached to the battery pack. Compared with traditional manual operation, this utility model greatly improves the shaping accuracy and efficiency.
[0007] Furthermore, it also includes a hinge assembly, which includes a first mounting block and a hinge shaft. The hinge shaft is disposed on the first mounting block, and one end of the positioning cover plate is hinged to the first mounting block through the hinge shaft.
[0008] In the above technical solution, one end of the positioning cover is hinged to the first mounting block via a hinge shaft, which allows the positioning cover to rotate at a certain angle relative to the support seat, making the placement and removal of the battery pack more convenient.
[0009] Furthermore, the hinge shaft is parallel to the battery pack to be shaped located within the groove.
[0010] In the above technical solution, the hinge shaft is designed to be parallel to the battery pack to be shaped located in the groove, so that the positioning cover can better limit the battery pack when closed, avoiding the risk of decreased shaping accuracy or damage to the battery pack due to shaking or displacement.
[0011] Furthermore, the other end of the positioning cover plate extends vertically outward to form an extension portion, and the support seat is provided with a snap-fit portion on one side relative to the first mounting block. When the positioning cover plate is pressed against the support seat, the extension portion and the snap-fit portion are engaged.
[0012] In the above technical solution, through the fastening structure of the extension part and the snap-fit part, the positioning cover can provide more stable support when pressing the battery pack, avoiding the risk of decreased shaping accuracy or damage to the battery pack caused by shaking or displacement, and improving the overall stability of the fixture.
[0013] Furthermore, the extension portion is provided with an opening, and the latching portion includes a second mounting block and a latch, the latch being elastically connected to the second mounting block so that the latch can extend into or out of the opening.
[0014] In the above technical solution, the latch and the second mounting block are elastically connected, which allows the latch to deform when subjected to external force and return to its original state after the external force is removed. This elastic connection allows the latch to extend into the opening when needed to achieve connection; when release is required, external force (such as manual operation) can deform the latch and remove it from the opening.
[0015] Furthermore, the latch also includes a handle for controlling the latch to extend out of the opening.
[0016] In the above technical solution, when the shaping is completed, the user operates the hand-held part to make the latch extend out of the opening, and then rotates the positioning cover to take out the shaped battery pack.
[0017] Furthermore, the support seat is also provided with two opposing clearance notches, which are located at the position where the support seat abuts against the positioning cover plate.
[0018] In the above technical solution, the main function of the clearance notch is to provide sufficient space so that the positioning cover can smoothly close onto the support and hold the battery to be shaped. At the same time, the operator can also apply high-temperature adhesive to both sides of the battery pack through the clearance notch.
[0019] Furthermore, it also includes a foot switch, which is electrically connected to the drive unit.
[0020] In the above technical solution, the foot switch allows operators to remotely control the working status of the drive unit by stepping on it without leaving the work area. This remote control method reduces operator movement and improves work efficiency and safety.
[0021] Compared with existing technologies, the advantages of this invention are as follows: By setting a groove on the support base, the battery pack to be shaped is placed in the groove, and then the positioning cover is flipped over, so that the positioning cover presses against the battery pack to be shaped, achieving a stable and limited position. At this time, the drive unit is activated, and the drive unit drives the shaping plate to move horizontally. When the shaping plate approaches the opening, the shaping plate abuts against one end face of the battery pack to be shaped. The drive unit provides a squeezing force on the shaping plate towards the side of the battery pack to be shaped, thereby achieving a shaping effect on the end of the battery pack to be shaped, ensuring that the nickel sheet at the end of the battery pack to be shaped is tightly attached to the battery. Compared with traditional manual operation, this invention greatly improves the shaping accuracy and efficiency. Attached Figure Description

[0034] The battery pack shaping fixture of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
[0035] Please refer to Figure 1 In a preferred embodiment, the battery pack shaping fixture of the present invention includes a base 1, a support seat 2 mounted on the base 1, a positioning cover plate 3 mounted on the base 1 and adjacent to the support seat 2, and a drive unit 4 mounted on the base 1 and located on one side of the support seat 2. The support seat 2 has a groove 201 for accommodating at least one set of battery packs to be shaped. The positioning cover plate 3 can rotate relative to the support seat 2 to press the battery packs to be shaped into the groove 201. The groove 201 has an opening 202 on the side near the drive unit 4. The output end of the drive unit 4 is connected to a shaping plate 401. The drive unit 4 is used to drive the shaping plate 401 to move horizontally so that the shaping plate 401 moves closer to or away from the opening 202.
[0036] Specifically, in this embodiment, the drive unit 4 includes a cylinder (choosing a cylinder has the advantage of low cost), a pressure regulating valve, and a controller. The cylinder is connected to the shaping plate 401, and the pressure regulating valve is installed on the side of the base 1 and communicates with the cylinder. By setting the pressure regulating valve, the gas pressure inside the cylinder can be adjusted, that is, the pressure applied by the shaping plate 401 to one end of the battery pack can be adjusted, avoiding severe deformation of the battery pack due to excessive force at both ends. The controller controls the flow of air to realize the propulsion and retraction of the cylinder.
[0037] During the battery pack manufacturing process, after the nickel sheets are welded onto the battery pack, the battery pack can be shaped using the shaping fixture provided by this utility model. This shaping process, performed after welding the nickel sheets, prevents the battery pack's electrical performance from being affected by insufficient adhesion between the nickel sheets and the battery pack. Specifically, a groove 201 is provided on the support base 2, and the battery pack to be shaped is placed inside the groove 201. Then, the positioning cover 3 is flipped, pressing it onto the battery pack to achieve a stable and limited position. At this time, the drive unit 4 is activated, driving the shaping plate 401 to move horizontally. When the shaping plate 401 approaches the opening 202, it abuts against one end face of the battery pack to be shaped. The drive unit 4 provides a pressing force to the shaping plate 401 towards the battery pack, thus shaping the end of the battery pack and ensuring a tight fit between the nickel sheets at the end of the battery pack. Compared with traditional manual operation, this invention greatly improves the accuracy and efficiency of shaping.
[0038] For example, the support 2 consists of a base plate and three side plates, that is, the base plate and the three side plates combine to form a groove 201, with the opening 202 of the groove 201 facing one of the side plates. In use, one set of battery packs is placed into the groove 201, with one end of the battery pack abutting against one of the side plates (opposite to the opening 202), and then another set of battery packs is placed into the groove 201, with the ends of the two battery packs abutting against each other. The aforementioned shaping operation is then performed.
[0039] To achieve the rotatable connection of the positioning cover 3, this utility model also includes a hinge assembly 5. The hinge assembly 5 includes a first mounting block 501 and a hinge shaft 502. The hinge shaft 502 is disposed on the first mounting block 501, and one end of the positioning cover 3 is hinged to the first mounting block 501 via the hinge shaft 502. This hinge connection allows the positioning cover 3 to rotate at a certain angle relative to the support seat 2, making the placement and removal of the battery pack more convenient. Furthermore, the hinged connection structure is relatively simple, which helps reduce the manufacturing cost of the shaping fixture. Specifically, during use, one or two battery packs are placed into the tank 201, and then the positioning cover 3 is rotated so that the positioning cover 3 contacts the battery pack, firmly pressing the battery pack into the tank 201. Then the drive unit 4 is activated to drive the shaping plate 401 close to the opening 202 to squeeze the end of the battery pack, thereby shaping the end of the battery pack. After the shaping is completed, the positioning cover 3 is rotated again, and then the shaped battery pack is taken out.
[0040] Based on the above embodiment, the hinge shaft 502 is parallel to the battery pack to be shaped within the groove 201. The hinge shaft 502 is designed to be parallel to the battery pack within the groove 201, allowing the positioning cover 3 to better limit the battery pack in the closed state, avoiding the risk of decreased shaping accuracy or damage to the battery pack due to shaking or displacement. Specifically, with the hinge shaft 502 parallel to the battery pack, when the positioning cover 3 is pressed against the support seat 2, the positioning cover 3 abuts against each battery in the width direction. In other words, the positioning cover 3 can limit each battery within the groove 201, ensuring shaping accuracy.
[0041] Please refer to Figure 2 and Figure 3 To ensure that the positioning cover plate 3 can stably press the battery pack during shaping, an extension portion 301 extends vertically outward from the other end of the positioning cover plate 3. A latching portion 6 is provided on one side of the support seat 2 relative to the first mounting block 501. When the positioning cover plate 3 is pressed against the support seat 2, the extension portion 301 engages with the latching portion 6. Through the engagement structure of the extension portion 301 and the latching portion 6, the positioning cover plate 3 provides more stable support when pressing the battery pack, avoiding the risk of decreased shaping accuracy or damage to the battery pack due to shaking or displacement, and improving the overall stability of the fixture.
[0042] For details, please refer to Figure 3 The extension portion 301 has an opening 3011, and the latching portion 6 includes a second mounting block 601 and a latch 602. The latch 602 is elastically connected to the second mounting block 601, allowing the latch 602 to extend into or out of the opening 3011. The elastic connection between the latch 602 and the second mounting block 601 allows the latch 602 to deform under external force and return to its original state after the force is removed. This elastic connection allows the latch 602 to extend into the opening 3011 when needed for connection; and to deform and exit the opening when release is required by external force (such as manual operation). After the latch 602 extends into the opening 3011, the positioning cover 3 cannot be easily moved or loosened, thus ensuring the stability and safety of the battery pack during the shaping process. After shaping, the latch 602 is extended out of the opening 3011, causing the positioning cover 3 to rotate.
[0043] Please refer to this again. Figure 3 It should be noted that the latching part 6 also includes a handle 603, which is used to control the latch 602 to extend out of the opening 3011. When the shaping is finished, the user operates the handle 603, and the latch 602 extends out of the opening 3011 under the action of elasticity. At this time, the user can rotate the positioning cover 3 to take out the shaped battery pack.
[0044] Please refer to Figure 4The support base 2 is also provided with two opposing clearance notches 203, which are located at the positions where the support base 2 and the positioning cover plate 3 abut. The main function of the clearance notches 203 is to provide sufficient space so that the positioning cover plate 3 can smoothly close onto the support base 2 and hold the battery to be shaped. At the same time, the operator can also apply high-temperature adhesive to both sides of the battery pack through the clearance notches 203. Specifically, in use, the two battery packs are placed into the tank 201 according to the above operation. After shaping, the positioning cover plate 3 is rotated to open the tank 201. Then, the operator applies high-temperature adhesive to the sides of the two battery packs through the clearance notches 203 to fix the two battery packs. Finally, the two battery packs are removed.
[0045] This invention also includes a foot switch 7, which is electrically connected to the drive unit 4. The foot switch 7 allows the operator to remotely control the operating status of the drive unit by stepping on it without leaving the work area. This remote control method reduces operator movement and improves work efficiency and safety.
