Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a battery assembly positioning fixture. Background Technology

[0002] In the assembly process of battery packs and PCB boards, it is often necessary to connect the through holes on the PCB board to the corresponding electrodes of the battery pack to achieve electrical connection and signal transmission. This assembly process requires extremely high alignment accuracy between the through holes on the PCB board and the electrodes, ensuring that each electrode can be accurately inserted into the corresponding through hole to avoid problems such as incomplete connection, misalignment, or electrode bending. This is especially true in scenarios such as new energy vehicle batteries and energy storage batteries where multiple electrodes are connected in series, often numbering in the dozens. The insertion accuracy directly determines the overall performance and reliability of the battery pack.

[0003] However, existing assembly methods have significant technical bottlenecks: First, the overall battery pack structure is prone to shaking when not fixed. Since battery packs are usually composed of multiple individual cells arranged side by side, their large weight and lack of rigid fixation make them prone to translational or rotational shifts on the assembly table, leading to instability in the spatial positioning of the electrodes. Second, the lack of electrode positioning directly leads to the accumulation of individual deviations: due to processing tolerances, fixing process defects, or stress release, electrodes are prone to translational shifts relative to the battery. In multi-electrode scenarios, if only the battery is positioned while the individual electrode positioning is ignored, the deviations between electrodes will accumulate. Even if the overall battery positioning is accurate, it is impossible to achieve synchronous docking of all electrodes with the PCB board vias, resulting in problems such as bending, short circuits, or loose connections of some electrodes.

[0004] Therefore, how to solve the stability problem of battery packs and electrode plates during the insertion process and achieve efficient, high-precision, and low-damage automated insertion has become a technical challenge that urgently needs to be overcome in this field.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Example:

[0024] See Figure 1 As shown, this embodiment provides a battery assembly positioning fixture, which includes: a mounting frame 100; and a battery fixing mechanism 200. The battery fixing mechanism 200 is disposed inside the mounting frame 100 and includes a support platform 220 and a first positioning component 230. The battery to be assembled is placed on the support platform 220. The first positioning component 230 includes two first pressure plates 232. The two first pressure plates 232 move relative to each other along a first direction X on opposite sides of the support platform 220 to clamp / release the battery to be assembled. A battery assembly is included; an electrode fixing mechanism 300 is connected to the mounting frame 100 and located above the battery fixing mechanism 200. The electrode fixing mechanism 300 includes two electrode positioning components 350 that can move relative to each other along the first direction X. Each electrode positioning component 350 includes a lifting frame 353 and multiple electrode pressing heads 360. The lifting frame 353 can move towards the battery to be assembled, and the multiple electrode pressing heads 360 are connected to the lifting frame 353 and are respectively positioned corresponding to multiple electrodes of the battery to be assembled. Further, this embodiment also includes a second detection component 370 to detect the actual pressing condition of the electrode pressing heads 360.

[0025] The battery assembly positioning fixture described in this embodiment uses the battery fixing mechanism 200 to laterally fix the battery body to be assembled, providing a stable clamping force from the side and effectively limiting the displacement of the battery body in the lateral direction. Simultaneously, the electrode fixing mechanism 300 presses and fixes multiple electrodes on the battery, ensuring that the electrodes maintain a precise position during assembly and preventing electrode misalignment from affecting the subsequent assembly accuracy with the PCB board.

[0026] It should be noted that, for ease of description, in this embodiment, the width direction of the battery assembly positioning fixture is defined as the first direction X, the length direction of the battery assembly positioning fixture is defined as the second direction Y, and the height direction of the battery assembly positioning fixture is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0027] In this embodiment, the mounting frame 100 serves as the basic load-bearing structure of the entire battery assembly and positioning fixture, providing a stable mounting platform for the battery fixing mechanism 200 and the electrode fixing mechanism 300. Specifically, the mounting frame 100 in this embodiment includes a base plate 110, a top frame 120, and multiple support columns 130. The base plate 110 is preferably a rectangular profile, the top frame 120 is configured as a hollow rectangular frame structure with the same dimensions as the base plate 110, and the four support columns 130 are respectively connected to the corners of the base plate 110 and the top frame 120.

[0028] The battery fixing mechanism 200 is primarily responsible for precisely fixing the battery body to be assembled. The support platform 220 provides a stable placement surface for the battery, ensuring the stability of the battery's bottom position during assembly. The two first pressure plates 232 in the first positioning assembly 230 can move relatively closer or further apart along the first direction X. When fixing the battery to be assembled, the two first pressure plates 232 apply clamping force from opposite sides of the support platform 220 to achieve lateral fixing of the battery and prevent lateral displacement of the battery during assembly; when it is necessary to remove or place the battery, the pressure plates move relatively apart to release the battery. Furthermore, using two first pressure plates 232 that can move along the first direction X for clamping and fixing can adapt to batteries of different sizes to be assembled, and has good versatility.

[0029] In this embodiment, the support platform 220 is provided with a plurality of limiting blocks 221, which are disposed at the edge of the support platform 220 to jointly enclose the support space, and the battery to be assembled is disposed in the support space.

[0030] See Figure 2 As shown, the core function of the multiple limiting blocks 221 is to jointly enclose a support space adapted to the battery to be assembled. When the battery to be assembled is placed in this support space, the limiting blocks 221 can block and constrain the battery from the circumference, forming a preliminary positioning effect. In this embodiment, a limiting block 221 is provided at each of the four corners of the support platform 220. This utility model does not impose specific limitations on the specific number and placement of the limiting blocks 221.

[0031] See Figure 3As shown, the first positioning component 230 further includes a first driver 231, which is disposed at the bottom of the support platform 220. One end of each of the two first pressure plates 232 is connected to the two working ends of the first driver 231, and the other ends are bent upwards toward the support platform 220. Each bent end of the first pressure plate 232 is provided with an elastic pressure head, which abuts against the side wall of the battery to be assembled. Specifically, when it is necessary to fix the battery, the first driver 231 drives the working ends of the two first pressure plates 232 to move closer together, causing the bent ends to move toward the side wall of the battery until the elastic pressure head abuts tightly against the side wall of the battery, clamping the battery by the force of the elastic pressure head. When it is necessary to release the battery, the first driver 231 drives the two working ends to move away from each other, and the first pressure plates 232 then drive the elastic pressure head to disengage from the side wall of the battery, releasing the clamping of the battery.

[0032] The first actuator 231 is preferably a double-headed cylinder, which is arranged at the bottom of the support platform 220 to minimize the volume of the first positioning component 230 and avoid interference between the structures. In different embodiments, the first actuator 231 can be set in different positions or configured as different structures according to actual applicable needs. This utility model does not impose specific restrictions on this.

[0033] In this embodiment, the battery fixing mechanism 200 further includes at least one second positioning component 240. The second positioning component 240 is disposed at one end of the support platform 220 in the second direction Y. It includes an assembly plate 243, a second driver 241, and a pusher 242. The assembly plate 243 is connected to one end of the support platform 220 in the second direction Y. The second driver 241 is disposed on the assembly plate 243. The pusher 242 is connected to the working end of the second driver 241 and can move along the second direction Y toward / away from the side wall of the battery to be assembled. The first positioning component 230 laterally clamps the battery from the first direction X, the limiting block 221 on the support platform 220 initially limits the battery from the circumferential direction, and the second positioning component 240 further fixes the battery from the second direction Y. The cooperation of multiple parties forms a more comprehensive and stable positioning effect, ensuring that the battery will not be displaced in multiple directions during the assembly process. Meanwhile, the way the second driver 241 drives the pusher 242 to move can be adjusted according to the different sizes and specifications of the batteries, thereby adapting to the size requirements of different batteries in the second direction Y, enhancing the versatility of the battery fixing mechanism 200, and enabling it to be applied to more types of battery assembly scenarios.

[0034] In this embodiment, the battery fixing mechanism 200 further includes a support platform 210 and a first detection component 250. The support platform 210 is disposed between the bearing platform 220 and the base plate 110 of the mounting frame 100. The first detection component 250 includes a detachable profile 251, a detection sensor 252, and a sensing plate 253. The detachable profile 251 is disposed on the support platform 210. The detection sensor 252 is detachably connected to the detachable profile 251. The sensing plate 253 is connected to the first pressure plate 232 and moves synchronously with the first pressure plate 232 to pass through / detach from the detection sensor 252. Specifically, when the first pressure plate 232 approaches the battery to be assembled and completes clamping and fixing, the sensing plate 253 moves with the first pressure plate 232 and passes through the detection sensor 252. After the detection sensor 252 detects the sensing plate 253, it sends a signal indicating that the first positioning component 230 has completed fixing the battery. When the first pressure plate 232 moves away from the battery and releases the battery, the sensing plate 253 moves with the first pressure plate 232 and disengages from the detection sensor 252. The detection sensor 252 sends a corresponding signal indicating that the battery is in the released state. Through this signal feedback, the working status of the first positioning component 230 can be monitored in real time.

[0035] See Figure 4 and Figure 5 As shown, the two electrode positioning components 350 in the electrode fixing mechanism 300 can move relative to each other along the first direction X, and can be adjusted according to the distribution position of the electrodes on the battery to ensure that the electrode pressing head 360 is precisely aligned with the electrode. The lifting frame 353 can move towards the battery to be assembled, driving the multiple electrode pressing heads 360 connected to it to approach and press the electrode, stabilizing the electrode in the preset position and preventing the electrode from shifting or tilting during assembly. In this embodiment, multiple electrode pressing heads 360 are respectively set for multiple electrodes, realizing the individual and precise pressing of each electrode, ensuring the positioning accuracy of all electrodes, and providing a key guarantee for the subsequent precise docking with the PCB board. In different embodiments, the specific number and setting position of the electrode pressing heads 360 can be adaptively adjusted according to the actual applicable needs, and this utility model does not impose specific limitations in this regard.

[0036] In this embodiment, the electrode fixing mechanism 300 further includes a mounting plate 310 and an opening / closing actuator 320. The mounting plate 310 is connected to the mounting frame 100, and the opening / closing actuator 320 is disposed on the mounting plate 310. The two electrode positioning components 350 are respectively connected to the two working ends of the opening / closing actuator 320. Similarly, the opening / closing actuator 320 is preferably a double-headed cylinder, which is connected to one end of the mounting frame 100 in the second direction Y.

[0037] Further, the electrode fixing mechanism 300 includes at least one opening / closing module 330 and two slides 340. The opening / closing module 330 is disposed on the top frame 120 of the mounting frame 100 and extends along the first direction X. One side of each slide 340 is slidably connected to the opening / closing module 330, and the electrode positioning assembly 350 is disposed on the slide 340. Specifically, the electrode positioning assembly 350 further includes a connecting plate 351 and a lifting driver 352. Part of the connecting plate 351 is connected to the slide 340, and the remaining part of the connecting plate 351 is connected to the lifting driver 352. Specifically, under the drive of the opening / closing module 330, the two slides 340 can move relatively closer or further apart along the first direction X. The electrode positioning assembly 350 is disposed on the slide 340 and moves synchronously with the movement of the slide 340, thereby realizing the position adjustment of the electrode positioning assembly 350 in the first direction X to adapt to the distribution position of electrodes on different batteries. The slide 340 is slidably connected to the opening and closing module 330 on one side. Part of the connecting plate 351 is connected to the slide 340, which serves to stably mount the electrode positioning assembly 350 on the slide 340, ensuring that the electrode positioning assembly 350 can move stably with the slide 340. The remaining connecting plate 351 is connected to the lifting driver 352, providing a stable mounting carrier for the lifting driver 352. The lifting driver 352 provides power for the movement of the lifting frame 353, driving the lifting frame 353 to move toward or away from the battery to be assembled, thereby driving the multiple electrode pressing heads 360 to complete the pressing, fixing or releasing action of the electrode.

[0038] Furthermore, in this embodiment, the lifting frame 353 includes a movable part 3531 and an extension part 3532, wherein the movable part 3531 is connected to the connecting plate 351, the middle part of the extension part 3532 is connected to the movable part 3531, and the extension part 3532 extends along the second direction Y. A plurality of electrode pressing heads 360 are disposed on the movable part 3531 and are spaced apart along the extension direction of the extension part 3532.

[0039] In this embodiment, the battery assembly positioning fixture further includes a control mechanism, and the battery fixing mechanism 200 and the electrode fixing mechanism 300 are respectively connected to the control mechanism. During actual production and processing, operators can use the control mechanism to adjust the above structure in real time, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0040] In summary, the battery assembly positioning fixture of this utility model, through the battery fixing mechanism 200, laterally fixes the battery body to be assembled, providing a stable clamping force from the side and effectively limiting the displacement of the battery body in the lateral direction. Simultaneously, the electrode fixing mechanism 300 presses and fixes multiple electrodes on the battery, ensuring that the electrodes maintain a precise position during assembly and preventing electrode misalignment from affecting the subsequent assembly accuracy with the PCB board. Thus, this fixture achieves a dual-point positioning and fixing effect for both the battery body and the electrodes. This dual-fixing mode significantly improves the stability and accuracy of the overall assembly, making it more suitable for PCB board assembly processes and laying a good foundation for subsequent welding, connection, and other operations. Compared with existing technologies, the battery assembly positioning fixture of this utility model, through its dual-point positioning design, simultaneously solves the positioning problem of the battery body and the electrodes, significantly improving the pass rate and production efficiency of PCB board assembly, and reducing the problem of low yield caused by inaccurate positioning. It has high practical application value in this industry.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
