Description

Technical Field

[0001] This utility model belongs to the technical field of battery manufacturing, specifically relating to a battery FPC bending device. Background Technology

[0002] Against the backdrop of the rapid rise of the new energy industry, the demand for various battery products, such as power batteries and energy storage batteries, continues to climb, and their manufacturing processes are constantly upgrading towards higher automation, higher integration, and higher reliability. Flexible printed circuit boards (FPCs) are widely used in battery modules to realize electrical connections between cells and circuit boards, and between cells themselves. They are key components for ensuring the stability of battery energy transmission and improving the space utilization of battery modules. As the requirements for energy density, safety, and miniaturization of battery products become increasingly stringent, the installation precision requirements for FPCs within battery modules are constantly increasing. The quality of their bending process directly affects the electrical performance, assembly efficiency, and lifespan of the battery. Therefore, developing FPC bending equipment that is suitable for battery manufacturing scenarios and combines speed and high precision has become an important requirement for promoting quality and efficiency improvement in the battery manufacturing industry. Currently, in battery manufacturing, the bending of FPC boards is mostly achieved through automated equipment. Generally, an FPC board consists of the FPC body and the FPC bending section extending from the body. However, existing FPC bending equipment adapted for battery manufacturing still cannot effectively balance the core requirements of speed and high precision in practical applications. On the one hand, due to the small structure of the FPC bending section and the limited operating space of the equipment, the FPC bending process in current cell manufacturing is usually completed sequentially by multiple stations to ensure bending accuracy. This results in a long cycle time for the FPC bending process, restricting overall production efficiency. Furthermore, the large size of the equipment occupies significant space on the production line. On the other hand, FPC boards typically contain intricately designed integrated modules, and the large equipment can easily damage the FPC board during bending, leading to increased battery defect rates, increased production costs, and delays in battery product delivery.

[0003] Therefore, when faced with small and structurally important FPC boards, how to provide an FPC bending device that can achieve fast, high-precision bending and good bending effect during battery manufacturing has become a technical problem that the current battery manufacturing industry urgently needs to solve.

[0021] Example 1: This embodiment provides a battery FPC bending device, which achieves high-precision, fast and high-yield bending results through the design of the position and structure of each component.

[0022] For details, please refer to the reference. Figures 1 to 4 The battery FPC bending equipment includes a worktable 100, on which a cell positioning unit 200 is provided. The cell positioning unit 200 is used to fix the position of the cell to facilitate subsequent bending operations on the FPC at the end of the cell. In this embodiment, the cell is a soft-pack battery and is horizontally fixed on the cell positioning unit 200. At this time, one end of the cell is to be bent into an FPC. It should be noted that the FPC mainly includes an FPC body 610 and an FPC bending portion 620 extending from the FPC body 610. The cell positioning unit 200 is provided with a working area for bending the FPC, and the FPC is exposed in the working area. A first pressure holding component 210 and a second pressure holding component 220 are respectively provided on the upper and lower sides of the working area. The output ends of the first pressure holding component 210 and the second pressure holding component 220 are arranged facing each other and move toward the working area to clamp the FPC body 610. The purpose is to improve the stability of the cell and the FPC body 610 structure and avoid displacement during the bending process.

[0023] Adjacent to the second pressure holding assembly 220, a bending pressure holding unit 300 is provided. The output end of the bending pressure holding unit 300 faces the working area and moves to hold pressure on the FPC bending part 620. The purpose is to ensure that the FPC bending part 620 is bent in place and to reshape the FPC bending part 620.

[0024] The battery FPC bending equipment also includes a rotary bending unit 400, which includes a gripper assembly 410 formed by two grippers 411 and a gripper motion assembly 420 that drives the gripper assembly 410. Driven by the gripper motion assembly 420, the gripper assembly 410 can clamp and rotate the FPC bending section 620 to achieve bending of the FPC bending section 620. The gripper assembly 410 has a clearance groove 412, and at least one gripper 411 has a detection window 413 communicating with the clearance groove 412. When the gripper assembly 410 clamps the FPC bending section 620, the clearance groove 412 provides clearance space for the integrated modules on the FPC bending section 620, preventing damage to the precision structure of the FPC during clamping, thus helping to reduce the defect rate and improve the yield rate in the bending process. Meanwhile, a vision unit 500 is also provided adjacent to the rotary bending unit 400. The vision unit 500 includes a first vision component 510, the imaging end of which faces the detection window 413. The first vision component 510 performs image acquisition on the FPC, especially using the detection window 413 to accurately position the bent portion 620 of the FPC. The position data acquired by the first vision component 510 can be fed back to the rotary bending unit 400 in real time to dynamically adjust the gripping position of the gripper component 410 on the FPC and to determine the position of the FPC after bending, thereby helping to improve the bending accuracy.

[0025] The specific workflow of this embodiment is as follows: The battery cell to be bent is placed on the battery cell positioning unit 200 of the workbench 100. After the position adjustment and fixation are completed, the first pressure holding component 210 moves towards the working area until it abuts against the FPC body 610 of the battery cell. The second pressure holding component 220 also moves towards the working area until it abuts against the FPC body 610 of the battery cell. The FPC body 610 is clamped between the first pressure holding component 210 and the second pressure holding component 220 to achieve the function of limiting and protecting the FPC body 610. Subsequently, the vision unit 500 collects data on the position of the battery cell, especially the position of the FPC bending part 620, so that the gripper component 410 can clamp the FPC bending part 620 according to the position information. After clamping and before formal bending, the first vision component 510 repositions the position of the FPC bending part 620 through the detection window 413, and adjusts the movement trajectory of the gripper motion component 420 according to the collected position information of the FPC bending part 620 to ensure accurate bending of the FPC.

[0026] After the FPC bending section 620 is initially bent, the bending and pressure holding unit 300 moves towards the working area and abuts against the initially bent FPC bending section 620 to reshape the FPC bending section 620 and ensure that the bending is in place. At this time, the bending is completed, and the rotating bending unit 400, the bending and pressure holding unit 300, the second pressure holding assembly 220, and the first pressure holding assembly 210 are sequentially retracted to their initial states. The cell positioning unit 200 releases its positioning of the cell to facilitate operation on the next cell.

[0027] In this embodiment, the first pressure holding component 210, the second pressure holding component 220, the bending and pressure holding unit 300, the rotary bending unit 400, and the vision unit 500 are all designed around the working area of ​​the cell positioning unit 200. Therefore, the bending of the FPC can be completed at a single station, saving the time spent moving between different stations, which helps to improve production efficiency and save space in the bending equipment. The gripper 411 is provided with a clearance groove 412 and a detection window 413. The clearance groove 412 helps to protect the delicate structure of the FPC bending part 620 and helps to reduce product loss caused by bending. The clearance groove 412, the detection window 413, and the vision unit 500 work together to achieve precise positioning of the FPC, improve the accuracy of the bending process, and ultimately make the battery FPC bending equipment of this application have the effects of high efficiency, speed, and high precision.

[0028] Example 2: This embodiment further supplements the structure based on Embodiment 1. Please refer to Embodiment 1 for further details. Figures 5-8 .

[0029] In this embodiment, reference Figure 7 The vision unit 500 also includes a second vision component 520. In the initial state, the detection window 413 is opposite to the first vision component 510. After the gripper component 410 completes its rotation, the detection window 413 rotates with it to a position opposite to the second vision component 520. That is, the first vision component 510 and the second vision component 520 respectively collect information on the position of the FPC before and after the gripper 411 rotation component rotates.

[0030] In this embodiment, to optimize the structural layout of the battery FPC bending equipment and to adapt to the bending process, the first vision component 510 and the second vision component 520 are preferably arranged facing each other in the vertical direction, and the gripper component 410 of the rotary bending unit 400 is located between the first vision component 510 and the second vision component 520. Specifically, the gripper 411 is arranged horizontally and located at the front end of the work area, the second vision component 520 is located below the work area and mounted on the worktable 100, and the first vision component 510 is located above the work area.

[0031] Further reference Figure 6 The battery cell positioning unit 200 includes a battery cell limiting fixture 230 and a vertical limiting component 240. The battery cell limiting fixture 230 has a battery cell limiting groove 231, and the front end of the battery cell limiting groove 231 has an opening to allow the FPC to be exposed, forming a working area in front of the opening. The top of the battery cell limiting groove 231 is hollowed out to facilitate the placement of the battery cell. At the same time, the vertical limiting component 240 limits the battery cell in the vertical direction above the battery cell limiting groove 231.

[0032] Specifically, in this embodiment, the vertical limiting component 240 is mounted on the workbench 100 and located outside the battery cell fixture. The vertical limiting component 240 includes a vertical limiting block 241 and a horizontal limiting drive structure 242 and a vertical limiting drive structure 243 connected in sequence to the vertical limiting block 241. The vertical limiting block 241 is located above the battery cell limiting groove 231 and is driven by the horizontal limiting drive structure 242 and the vertical limiting drive structure 243 to move away from or towards the battery cell limiting groove 231. In the initial state, the vertical limiting block 241 is located diagonally above the battery cell limiting groove 231 to facilitate the placement of the battery cell. After the battery cell is placed in the battery cell limiting slot 231, the horizontal limiting drive structure 242 moves, causing the vertical limiting block 241 to move horizontally until it is directly above the battery cell. Then, the vertical limiting drive structure 243 moves, causing the horizontal limiting drive structure 242 and the vertical limiting block 241 to move downwards as a whole until the vertical limiting block 241 abuts against the top of the battery cell. The vertical limiting block 241 and the battery cell limiting fixture 230 together realize the vertical movement of the battery cell. The horizontal limiting drive structure 242 and the vertical limiting drive structure 243 can be connected slide cylinders.

[0033] It should be noted that, in this embodiment, the vertical limiting component 240 and the horizontal limiting component 250 are located on the same side of the cell limiting groove 231 to improve the compactness of the equipment structure.

[0034] Furthermore, the battery cell positioning unit 200 also includes a horizontal limiting component 250, which includes a horizontal limiting block 251 and a second horizontal limiting drive structure. The battery cell limiting fixture 230 is also provided with an adjustment groove 232 that connects the battery cell limiting groove 231 in the left-right direction. The horizontal limiting block 251 moves between the adjustment groove 232 and the battery cell limiting groove 231. The horizontal limiting block 251 is driven by the second horizontal limiting drive structure to move horizontally. When the battery cell is placed in the battery cell limiting groove 231, the second horizontal limiting drive structure moves, causing the horizontal limiting block 251 to move towards the battery cell limiting groove 231 until the horizontal limiting block 251 engages with the battery cell limiting fixture 230, achieving horizontal clamping and limiting of the battery cell. The second horizontal limiting drive structure can be a cylinder or a servo motor.

[0035] It should be noted that, in order to facilitate the adjustment and fixation of the battery cell position, after the battery cell is placed in the battery cell limiting groove 231, it is first limited by the horizontal limiting component 250 and then by the vertical limiting component 240.

[0036] After the battery cell is positioned, preparations are needed before the bending process. The first pressure holding assembly 210 and the second pressure holding assembly 220 position and stabilize the FPC of the battery cell. Specifically, the first pressure holding assembly 210 is mounted on the worktable 100. The first pressure holding assembly 210 includes a first pressure holding block 211 and a pressure holding vertical drive structure 212 connected to the first pressure holding block 211. The lower end of the first pressure holding block 211 is provided with a first pressure holding surface, which extends horizontally and is adapted to the FPC body 610.

[0037] The second pressure holding assembly 220 is located below the working area and includes a second pressure holding block 221 and a pressure holding vertical drive structure 222 connected to the second pressure holding block 221. The upper end of the second pressure holding block 221 is provided with a second pressure holding surface, which extends horizontally and the length of the second pressure holding surface in the horizontal direction is less than that of the first pressure holding surface.

[0038] Before bending the FPC bending section 620, the first pressure holding block 211 moves towards the working area under the action of the pressure holding vertical drive structure 212 until it abuts against the upper part of the FPC body 610. Subsequently, the second pressure holding block 221 moves towards the working area under the action of the pressure holding vertical drive structure 222 until it abuts against the lower part of the FPC body 610. The first pressure holding block 211 and the second pressure holding block 221 clamp the FPC body 610. It should be noted that in this embodiment, the length of the second pressure holding surface in the horizontal direction is less than that of the first pressure holding surface, the purpose of which is to provide space for bending of the bending section.

[0039] The bending and pressure holding unit 300 is located below the working area and includes a third pressure holding block 310 and a pressure holding vertical drive structure 311 connected to the third pressure holding block 310. The upper end of the third pressure holding block 310 is provided with a third pressure holding surface, and both the third pressure holding surface and the second pressure holding surface are arranged along the extension direction of the first pressure holding surface. After the rotary bending unit 400 completes the initial bending, the third pressure holding block 310 moves upward under the action of the pressure holding vertical drive structure 311 until it abuts against the lower end surface formed after the FPC bending part 620 is bent. The third pressure holding block 310 applies pressure again to the FPC bending part 620 to ensure that the bending is in place and improve the accuracy of the bending process.

[0040] Each of the grippers 411 in the gripper assembly 410 is provided with a gripping surface 414. In order to balance the stability of gripping the FPC bending portion 620 and to protect the structure of the FPC bending portion 620, in this embodiment, one gripper 411 is provided with a complete gripping surface 414 extending in the horizontal direction. The other gripper 411 is recessed from the gripping surface 414 to form a clearance groove 412, and a detection window 413 is provided on the gripper 411 that communicates with the clearance groove 412. The projection of the detection window 413 in the gripping direction coincides with the clearance groove 412, so as to facilitate the vision unit 500 to position the FPC bending portion 620.

[0041] Example 3: This embodiment further optimizes the structure based on embodiment 2. The following is a description of the structural optimizations based on embodiment 2, with reference to... Figure 9 Explanation of the supplementary content.

[0042] To ensure the accuracy of the battery FPC bending equipment, the gripper motion assembly 420 includes a first-direction drive structure 421, a second-direction drive structure 422, and a third-direction drive structure 423 connected in sequence, wherein the first, second, and third directions are perpendicular to each other. In this embodiment, the first-direction drive structure 421, the second-direction drive structure 422, and the third-direction drive structure 423 are all slide cylinders. Movable plates are provided between the first-direction drive structure 421 and the second-direction drive structure 422, and between the second-direction drive structure 422 and the third-direction drive structure 423. The drive end moves the drive structure at the driven end through the movable plates.

[0043] In this embodiment, the first directional drive structure 421 is a slide cylinder arranged in the left-right direction, which, through the transmission of other structures, ultimately realizes the movement of the gripper assembly 410 in the left-right direction; the second directional drive structure 422 is a slide cylinder arranged in the front-back direction, which, through the transmission of other structures, ultimately realizes the movement of the gripper assembly 410 in the front-back direction; the third directional drive structure 423 is a slide cylinder arranged in the vertical direction, which, through the transmission of other structures, ultimately realizes the movement of the gripper assembly 410 in the vertical direction. During operation, based on the position feedback from the vision unit 500, the first directional drive structure 421 and the third directional drive structure 423 move in real time to adjust the gripper assembly 410 to a position adapted to the FPC bending section 620. Before and after completing the bending process, the gripper assembly 410 moves in the front-back direction under the action of the second directional drive structure 422 to move closer to or further away from the work area, facilitating the placement of the battery cell and the bending of the battery cell's FPC.

[0044] Furthermore, the gripper assembly 410 also includes a clamping drive structure 414 and a rotation drive assembly 415. The clamping drive structure 414 is connected to the drive end of the rotation drive assembly 415 and rotates. At least one gripper 411 in the gripper assembly 410 is connected by the clamping drive to move closer to or away from the other gripper 411 to achieve opening and closing between the different grippers 411. In this embodiment, one end of the rotation drive assembly 415 is connected to the drive end of the third-direction drive structure 423, and the other end is connected to the clamping drive structure 414. Both grippers 411 in the gripper assembly 410 are respectively connected to the clamping drive structure 414.

[0045] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
