[0054] The present application proposes a gantry ring rail system.

[0055] Please refer to Figure 1 andFigure 2 In one embodiment of the present invention, the bending machine line includes a base 10, a feeding conveyor 20, a ring rail drive line 30, multiple fixing mechanisms 40, a position adjustment mechanism 50, a terminal bending mechanism 60, and a discharge conveyor 70. The feeding conveyor 20 is disposed on the base 10. The ring rail drive line 30 is disposed on the base 10 and located below the feeding conveyor 20. Multiple fixing mechanisms 40 are spaced apart on the ring rail drive line 30, and each fixing mechanism 40 is used for the flexible circuit board to be processed. The position adjustment mechanism 50 is disposed on the base 10 and located outside the ring rail drive line 30. The terminal bending mechanism 60 is mounted on the base 10 and is arranged adjacent to the position adjustment mechanism 50. The discharge conveyor 70 is disposed on the base 10 and located above the ring rail drive line 30. The position adjustment mechanism 50 and the terminal bending mechanism 60 are arranged spaced apart around the ring rail drive line 30.

[0056] The base 10 is the fundamental structure of the entire bending machine line, used to support and secure all other components. It is typically made of robust materials to ensure the stability and durability of the equipment. The design of the base 10 takes into account the overall layout and operating space of the equipment to achieve optimal production efficiency.

[0057] The feed line 20, located on the base 10, is responsible for conveying the flexible printed circuit boards (FPCs) to be processed into the equipment. This line is typically equipped with an automated feeding mechanism, enabling a continuous supply of FPCs, thereby reducing manual intervention and improving production efficiency. The design of the feed line 20 allows the FPCs to enter the next processing stage in the correct orientation and position.

[0058] A circular track conveyor 30 is mounted on the base 10 and located below the feed line 20. It is a closed-loop transport system used for the cyclic transport of FPCs within the equipment. The design of the circular track conveyor 30 allows the FPCs to move smoothly between different processing stations, ensuring that each FPC undergoes all necessary processing steps. Multiple fixing mechanisms 40 are spaced apart on the circular track conveyor 30, each fixing mechanism 40 used to secure the flexible circuit board to be processed. These fixing mechanisms 40 are typically equipped with a vacuum suction system or other clamping devices to ensure the FPC remains stable during processing. The design of the fixing mechanisms 40 takes into account the size and shape of the FPCs to accommodate different types of FPCs.

[0059] The position adjustment mechanism 50 is mounted on the base 10 and located outside the ring rail drive line 30. Its function is to precisely adjust the position of the FPC to ensure that the FPC is in the correct position during bending. The position adjustment mechanism 50 typically includes multiple adjustment components, such as cylinders, sliders, and guide rails, which work together to achieve precise position control.

[0060] The terminal bending mechanism 60 is mounted on the base 10 and is arranged adjacent to the position adjustment mechanism 50. Its main function is to bend the terminal portions of the FPC. The terminal bending mechanism 60 typically includes multiple bending components, such as pressure blocks, cylinders, and guide rails, which work together to achieve precise bending angles and shapes. The design of the terminal bending mechanism 60 takes into account the material properties and bending requirements of the FPC terminals to ensure bending quality.

[0061] The discharge assembly line 70 is mounted on the base 10 and located above the ring rail drive line 30. Its function is to output the processed FPCs from the equipment. The discharge assembly line 70 is usually equipped with an automatic unloading mechanism, which can continuously collect the processed FPCs, thereby reducing manual intervention and improving production efficiency.

[0062] The FPC (Flexible Printed PC) enters the equipment from the feeding line 20, ensuring it is in the correct orientation and position. The FPC is then conveyed to the circular track drive line 30, where it begins to circulate within the equipment. On the circular track drive line 30, each FPC is secured by a fixing mechanism 40 to ensure stability during processing. Before bending, the FPC is adjusted to the correct position by a position adjustment mechanism 50 to ensure bending accuracy. The terminal portions of the FPC are precisely bent by a terminal bending mechanism 60 to meet design requirements. The completed FPC is then conveyed to the output line 70, ready for delivery.

[0063] This technical solution achieves accurate bending of flexible circuit boards (FPCs) through innovative designs such as the integration of a multi-functional mechanism, high-precision position adjustment, a stable fixing mechanism 40, a precise terminal bending mechanism 60, and an optimized ring rail transmission line 30, significantly improving the bending quality of FPCs. Increased automation and integration reduce manual intervention, enhancing equipment adaptability and production efficiency. The introduction of a quality control and feedback system ensures that each FPC achieves the expected bending quality, thereby improving the reliability of signal transmission within the battery cell and the overall quality and performance of the battery cell product.

[0064] In one embodiment, please refer to Figure 1 and Figure 2 The bending machine line also includes a first transfer mechanism 80 and a secondary positioning mechanism 90 located on the base 10. The first transfer mechanism 80 is located above the feeding line 20 and is adjacent to the secondary positioning mechanism 90. The first transfer mechanism 80 is used to place the unprocessed flexible circuit board from the feeding line 20 into the secondary positioning mechanism 90, and the secondary positioning mechanism 90 is used to accurately position the flexible circuit board.

[0065] In this technical solution, the first transfer mechanism 80 is mounted on the base 10, located above the feeding line 20, and adjacent to the secondary positioning mechanism 90. Its main function is to accurately place the unprocessed flexible circuit board (FPC) from the feeding line 20 onto the secondary positioning mechanism 90. The first transfer mechanism 80 is capable of moving in both vertical and horizontal directions to achieve precise transfer of the FPC. The design of the transfer mechanism takes into account the size and shape of the FPC to ensure that no damage is caused to the FPC during the transfer process.

[0066] The secondary positioning mechanism 90 is used to precisely position the flexible printed circuit board (FPC) to ensure it is in the correct position during bending. This mechanism typically includes multiple positioning components, such as positioning pins, clamps, or vacuum suction devices, which work together to achieve precise alignment of the FPC. The secondary positioning mechanism 90 is designed to accommodate different types of FPCs, taking into account their wiring density and thickness.

[0067] During the operation of the bending machine line, various components work together to achieve automatic bending of the FPC. The FPC enters the equipment from the feeding line 20, in the correct direction and position. The unprocessed FPC is picked up from the feeding line 20 by the first transfer mechanism 80 and accurately placed onto the secondary positioning mechanism 90. Precise control of the transfer mechanism ensures correct placement of the FPC. The FPC is precisely positioned on the secondary positioning mechanism 90. Multiple components of the positioning mechanism work together to ensure the FPC is in the correct position before bending. The positioned FPC is conveyed to the circular track drive line 30 and begins to circulate within the equipment. On the circular track drive line 30, each FPC is fixed by the fixing mechanism 40 to ensure stability during processing. Before bending, the FPC is adjusted to the correct position by the position adjustment mechanism 50 to ensure bending accuracy. The terminal portions of the FPC are precisely bent by the terminal bending mechanism 60 to meet design requirements. The processed FPC is conveyed to the discharge line 70, ready for output.

[0068] The precise positioning function of the secondary positioning mechanism 90 ensures that the FPC is in the correct position before bending, thereby improving bending accuracy. The precise control of the first transfer mechanism 80 reduces FPC transfer time and improves production efficiency. The stable fixing mechanism 40 and the smooth transmission of the ring rail drive line 30 ensure the stability of the FPC during processing and reduce processing errors. Through the coordinated work of the first transfer mechanism 80 and the secondary positioning mechanism 90, the bending machine line achieves efficient and precise bending of the FPC, demonstrating significant technical benefits and application value.

[0069] The first transplanting mechanism 80 includes a first gantry and a first robotic arm. The first gantry is mounted on the base 10 and located above the feeding line 20 and the discharging line 70. A ring track drive line 30 is spaced apart from the first gantry. The first robotic arm is movably connected to the first gantry and is used to transfer flexible circuit boards from the feeding line 20 to the fixing mechanism 40 on the ring track drive line 30, and to transfer flexible circuit boards from the fixing mechanism 40 on the ring track drive line 30 to the discharging line 70. The first gantry includes a first frame and a first linear module. The first frame is mounted on the base 10. The first linear module is mounted on the first frame, and its output end is connected to the first robotic arm. The first linear module is used to drive the first robotic arm to move horizontally.

[0070] In one embodiment, please refer to Figure 1 and Figure 2 The bending machine line also includes a second transfer mechanism 100 located on the base 10. The second transfer mechanism 100 is located between the secondary positioning platform and the position adjustment mechanism 50, and is on the outside of the ring rail transmission line 30. It is used to transfer the flexible circuit board that was positioned in the secondary positioning to the position adjustment mechanism 50.

[0071] The second transplanting mechanism 100 is mounted on the base 10, located between the secondary positioning platform and the position adjustment mechanism 50, and on the outside of the ring rail transmission line 30. Its main function is to transfer the flexible circuit board (FPC) after secondary positioning to the position adjustment mechanism 50. The second transplanting mechanism 100 is capable of moving in both vertical and horizontal directions to achieve precise transplantation of the FPC. The design of the transplanting mechanism takes into account the size and shape of the FPC to ensure that no damage is caused to the FPC during the transplantation process.

[0072] After secondary positioning, the FPC is picked up from the secondary positioning platform by the second transplanting mechanism 100 and accurately placed onto the position adjustment mechanism 50. The precise control of the second transplanting mechanism 100 reduces the transplanting time of the FPC and improves production efficiency.

[0073] The precise control of the first transplanting mechanism 80 and the second transplanting mechanism 100 reduces the transplanting time of the FPC and improves production efficiency. Through the coordinated work of the first transplanting mechanism 80, the secondary positioning platform, the second transplanting mechanism 100, and the position adjustment mechanism 50, the bending machine line achieves efficient and precise bending of the FPC.

[0074] The first gantry also includes a second frame and a second linear module. The second frame is mounted on the first frame and located on one side of the first frame. The second linear module is mounted on the second frame, and the movement direction of the second linear module is set at an angle to the movement direction of the first linear module. The second transplanting mechanism 100 is a second robotic arm connected to the output end of the second linear module. The secondary positioning platform is mounted on the base 10 and located between the first frame and the feeding line 20, and is used for secondary positioning of the flexible circuit board.

[0075] In one embodiment, the bending machine line also includes a barcode scanning mechanism 110 disposed on the base 10. The barcode scanning mechanism 110 is located inside the ring rail transmission line 30 and is used to scan the product code of the flexible circuit board on the ring rail transmission line 30.

[0076] The scanning mechanism 110 is mounted on the base 10 and located within the ring track drive line 30. Its main function is to scan the product codes on the flexible printed circuit boards (FPCs) on the ring track drive line 30. The scanning mechanism 110 typically includes one or more high-precision scanners capable of quickly and accurately reading the product codes on the FPCs. The design of the scanning mechanism 110 takes into account the size of the FPCs and the location of the codes to ensure accurate identification of product information for each FPC during the scanning process.

[0077] The adjusted FPC is conveyed onto the circular track conveyor 30 and begins to circulate within the equipment. As the FPC on the circular track conveyor 30 passes the barcode scanning mechanism 110, the barcode scanning mechanism 110 scans its product code to ensure that the product information of each FPC is accurately recorded.

[0078] Through the integration of the barcode scanning mechanism 110, the bending machine line not only achieves efficient and precise bending of FPCs, but also enhances product tracking and quality control capabilities. The barcode scanning mechanism 110 ensures that the product code of each FPC is accurately read and recorded, thereby improving the automation level and product traceability of the production line. This collaborative workflow significantly improves production efficiency and product quality, ensuring the reliability and stability of signal transmission within the battery cell.

[0079] In one embodiment, please refer to Figure 1 and Figure 2 The bending machine line also includes a waste unloading line 120, which is located on the base 10 and on the side of the feeding line 20 away from the secondary positioning platform. It is used for the first transfer mechanism 80 to transfer the waste from the fixed mechanism 40 to the waste unloading line 120.

[0080] The scrap unloading line 120 is mounted on the base 10, located on the side of the feed line 20 away from the secondary positioning platform. Its main function is to receive and transport scrap FPCs identified during the production process. The scrap unloading line 120 is typically equipped with an automatic identification and separation system that can separate non-conforming FPCs from the production line and guide them to a dedicated scrap collection area. This design helps maintain the cleanliness and efficiency of the production line while ensuring that scrap is properly handled.

[0081] During processing, defective FPCs are identified by a built-in quality inspection system. The identified defective FPCs are picked up from the stationary mechanism 40 by the first transfer mechanism 80 and transferred to the waste discharge line 120. The defective FPCs are then transported to the waste collection area for further processing.

[0082] By integrating the scrap unloading line 120, the bending machine line not only achieves efficient and precise bending of FPCs, but also significantly improves product quality control. The scrap unloading line 120 ensures that defective products are identified and removed promptly, thereby reducing errors and waste in production. This collaborative workflow improves the overall efficiency and reliability of the production line, ensuring high quality and consistency of the final product.

[0083] In one embodiment, please refer to Figures 2 to 4 The position adjustment mechanism 50 includes a pre-bending component 51 and at least one correction component 52. The pre-bending component 51 is disposed on the base 10; the correction component 52 is disposed on the base 10; wherein the pre-bending component 51 and the correction component 52 are arranged at intervals on the outer side of the ring rail transmission line 30, and the correction component 52 is disposed adjacent to the terminal bending mechanism 60.

[0084] In this embodiment, the pre-bending assembly 51 is mounted on the base 10 and is an important component of the position adjustment mechanism 50. Its main function is to perform preliminary bending of the FPC to ensure that the FPC is in the correct position during subsequent processing. The pre-bending assembly 51 typically includes a bending tool and a drive mechanism, enabling precise pre-bending operations based on the characteristics of the FPC and bending requirements. The design of the pre-bending assembly 51 takes into account the material properties and thickness of the FPC to ensure the accuracy and consistency of the pre-bending.

[0085] The alignment correction assembly 52 is mounted on the base 10 and arranged at intervals from the pre-bending assembly 51 on the outer side of the ring rail drive line 30. The main function of the alignment correction assembly 52 is to correct the position of the FPC, ensuring that the FPC does not shift during the bending process. The alignment correction assembly 52 typically includes sensors, a controller, and an adjustment mechanism, capable of monitoring the FPC's position in real time and making precise adjustments. The alignment correction assembly 52 is arranged adjacent to the terminal bending mechanism 60 to ensure that the FPC is in the correct position before bending.

[0086] The FPC on the ring track transmission line 30 first passes through the pre-bending assembly 51 for preliminary bending. The pre-bending assembly 51 performs precise pre-bending operations according to the characteristics of the FPC and bending requirements. After pre-bending, the FPC continues to move to the correction assembly 52, which monitors the position of the FPC in real time and makes precise adjustments to ensure that the FPC does not shift during the bending process. The corrected FPC is then precisely bent by the terminal bending mechanism 60 to meet design requirements.

[0087] Precise control of the pre-bending assembly 51 and the correction assembly 52 ensures that the FPC is in the correct position before bending, thereby improving bending accuracy. The real-time monitoring and adjustment function of the correction assembly 52 ensures the stability of the FPC during processing and reduces processing errors.

[0088] In one embodiment, please refer to Figures 2 to 4 The pre-bending assembly 51 includes a mounting frame 511, a clamping assembly 512, and a shaping and combing assembly 513.

The clamping assembly 512 is used to clamp and bend the flexible circuit board of the battery cell, and the shaping and combing assembly 513 is used to shape and comb the flexible circuit board of the battery cell.

[0089] The precise control of the clamping assembly 512 ensures that the FPC is in the correct position before pre-bending, thereby improving the accuracy of pre-bending. The precise operation of the shaping and combing assembly 513 ensures that the FPC maintains the correct shape and position during bending, improving the quality of shaping and combing. Through the coordinated work of the mounting bracket 511, the clamping assembly 512, and the shaping and combing assembly 513, the pre-bending assembly 51 achieves efficient and precise pre-bending and shaping of the FPC.

[0090] The clamping assembly 512 includes a first telescopic cylinder, a first rotary cylinder, and a finger-gripping cylinder. The first telescopic cylinder is movably connected to the mounting frame 511. The first rotary cylinder is connected to the output end of the first telescopic cylinder. The finger-gripping cylinder is connected to the output end of the first rotary cylinder, and the output end of the finger-gripping cylinder is provided with a gripper. The clamping assembly 512 also includes a first lifting cylinder disposed on the mounting frame 511, and the output end of the first lifting cylinder is connected to the first telescopic cylinder.

[0091] The shaping and combing assembly 513 includes at least two second telescopic cylinders and at least two connecting rods. The two second telescopic cylinders are movably connected to the mounting frame 511 and are symmetrically arranged. Each connecting rod is connected to the output end of one of the second telescopic cylinders. One connecting rod is provided with multiple first clamping portions, and the other connecting rod is provided with multiple second clamping portions. The two second telescopic cylinders drive the two connecting rods to move closer together, so that each first clamping portion and each second clamping portion clamps a flexible circuit board. The shaping and combing assembly 513 also includes a second lifting cylinder and a third telescopic cylinder. The second lifting cylinder is located on the mounting frame 511. The third telescopic cylinder is connected to the output end of the second lifting cylinder, and the output end of the third telescopic cylinder is connected to the two second telescopic cylinders. The telescopic direction of the third telescopic cylinder is perpendicular to the telescopic direction of the second telescopic cylinders. Both the first clamping portion and the second clamping portion are non-conductive.

[0092] In one embodiment, please refer to Figures 2 to 4 The correction component 52 includes a bracket 521, a correction element 522, and a first bending element 523. The bracket 521 is located on the base 10; the correction element 522 is installed on the bracket 521; and the first bending element 523 is installed on the bracket 521 and located below the correction element 522. The correction element 522 is used to correct the position of the flexible circuit board on the fixing mechanism 40, and the first bending element 523 is used to bend the flexible circuit board.

[0093] The FPC on the ring track drive line 30 first passes through the correction assembly 52. ​​The correction assembly 522 corrects the position of the FPC, ensuring that the FPC is in the correct position during the bending process. After correction, the FPC continues to move to the first bending assembly 523, which performs precise bending on the FPC to meet the design requirements.

[0094] The precise control of the alignment component 522 ensures that the FPC is in the correct position before bending, thereby improving bending accuracy.

The stable support of the bracket 521 and the precise adjustment function of the alignment component 522 ensure the stability of the FPC during processing, reducing processing errors.

[0095] The correction component 522 includes a first mounting plate, at least one rotary cylinder, and at least one finger-clamping cylinder. The first mounting plate is mounted on the mounting bracket 521. The rotary cylinder is movably connected to the first mounting plate. The finger-clamping cylinder is connected to the output end of the rotary cylinder and is used to clamp the flexible circuit board to be corrected.

[0096] The correction assembly 52 further includes at least one vertical straight module, at least one horizontal straight module, and at least one mounting frame.

[0098] In one embodiment, please refer to Figure 2 and Figure 5 The terminal bending mechanism 60 includes a fixed frame 61, a second bending member 62, and a bending seat 63. The fixed frame 61 is disposed on the base 10; the second bending member 62 is movably connected to the fixed frame 61; and the bending seat 63 is movably connected to the base 10 and is spaced apart from the fixed frame 61.

[0099] In this technical solution, the fixing bracket 61 is mounted on the base 10 and serves as the main support structure for the terminal bending mechanism 60. Its design considers the stability and operating space of the entire mechanism, ensuring that the second bending member 62 and the bending seat 63 can perform their functions in the correct positions. The fixing bracket 61 is typically made of a robust material to withstand the forces generated during the bending process.

[0100] The second bending member 62 is movably connected to the fixing frame 61 and is used to bend the FPC terminal. The second bending member 62 typically includes a bending tool and a drive mechanism, enabling precise bending operations according to the characteristics and bending requirements of the FPC terminal. The design of the second bending member 62 takes into account the material properties and thickness of the FPC terminal to ensure the accuracy and consistency of the bending.

[0101] The bending seat 63 is movably connected to the base 10 and spaced apart from the fixing bracket 61. The main function of the bending seat 63 is to support the FPC and ensure it maintains the correct position during bending. The bending seat 63 typically includes positioning components and a support structure, which can be adjusted according to the size and shape of the FPC. The design of the bending seat 63 takes into account the wiring density and thickness of the FPC to ensure that the FPC is not damaged during bending.

[0102] The corrected FPC is conveyed to the terminal bending mechanism 60. A fixing frame 61 provides stable support, a second bending member 62 precisely bends the FPC terminals, and a bending seat 63 supports the FPC and ensures it remains in the correct position during bending. The processed FPC is then conveyed to the output line 70, ready for delivery.

[0103] Through the coordinated operation of the fixing frame 61, the second bending member 62, and the bending seat 63, the precise control of the second bending member 62 ensures that the FPC terminals are in the correct position before bending, thereby improving bending accuracy. The precise support function of the bending seat 63 ensures that the FPC maintains the correct shape and position during bending, improving bending quality. The stable support of the fixing frame 61 and the precise bending function of the second bending member 62 ensure the stability of the FPC during processing and reduce processing errors.

[0104] In one embodiment, please refer to Figure 2 and Figure 5 The second bending member 62 includes a driving member 621, a limiting block 622, and an adjusting arm 623. The driving member 621 is mounted on the fixed frame 61. The limiting block 622 is connected to the output end of the driving member 621. The adjusting arm 623 is connected to the output end of the driving member 621 and is spaced apart from the limiting block 622. A contact roller is provided at the end of the adjusting arm 623 away from the driving member 621.

[0105] The drive unit 621, mounted on the fixed frame 61, is the power source for the second bending member 62. Its main function is to provide power to drive the limit block 622 and the adjusting arm 623 to perform the bending operation. The drive unit 621 typically includes a motor, cylinder, or other power device, capable of precise control based on the characteristics of the FPC terminal and bending requirements. The design of the drive unit 621 takes into account the force and speed required during the bending process to ensure the accuracy and consistency of the bending.

[0106] The limiting block 622 is connected to the output end of the drive component 621 and is used to limit the bending position of the FPC terminal. The limiting block 622 typically includes a fixed part and an adjustable part, which can be adjusted according to the size and shape of the FPC terminal. The design of the limiting block 622 takes into account the material properties and thickness of the FPC terminal to ensure the accuracy and consistency of bending.

[0107] The adjusting arm 623 is connected to the output end of the drive unit 621 and is spaced apart from the limiting block 622. The main function of the adjusting arm 623 is to adjust the bending angle and position of the FPC terminal. The adjusting arm 623 typically includes a rotatable arm and an adjusting mechanism, capable of precise adjustment according to the characteristics and bending requirements of the FPC terminal. The design of the adjusting arm 623 takes into account the wiring density and thickness of the FPC terminal to ensure the accuracy and consistency of bending.

[0108] A contact roller is located at the end of the adjusting arm 623 furthest from the drive member 621, and is used to contact the FPC terminal and perform bending operations. The contact roller typically includes a roller and a support structure, and can be adjusted according to the size and shape of the FPC terminal. The design of the contact roller takes into account the material properties and thickness of the FPC terminal to ensure accuracy and consistency in bending.

[0109] The precise control of the drive element 621 and the limiting function of the limit block 622 ensure that the FPC terminal is in the correct position before bending, thereby improving the bending accuracy. The precise adjustment function of the adjusting arm 623 and the contact operation of the contact roller ensure that the FPC terminal maintains the correct angle and position during bending, thereby improving the bending quality.
