Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, and specifically discloses a fully automatic bending and laser peeling production line for steel bars of new energy batteries. Background Technology

[0002] Connector pins in new energy batteries (such as power batteries and energy storage batteries) are key components for achieving electrical connections within battery modules. With the increasing demands for energy density and lightweight design in the new energy vehicle and energy storage industries, battery connector pins are evolving towards higher conductivity, higher strength, thinner walls, and more complex shapes. Currently, a common manufacturing process involves using steel or copper strips, employing continuous feeding and rotary bending to process flat metal strips into finished products with complex spatial shapes to meet the compact layout requirements of battery modules. Simultaneously, to ensure the insulation performance and safety of the connector pins, the bent workpieces typically undergo a laser peeling process to precisely remove the insulation layer in designated areas, exposing the metal substrate for subsequent welding.

[0003] Existing fully automated bending production lines typically include a continuously feeding rotary conveyor. This mechanism uses traction or clamping to stably transport coiled flat metal bars (such as steel or copper bars) to subsequent workstations according to a preset cycle and length. A rotary continuous bending machine is arranged along the conveying path. The bending machine is usually equipped with multiple rotating or oscillating bending rollers. When the conveyor delivers the metal bar to the predetermined position, the bending rollers, through relative motion (such as rotation around the workpiece or radial feeding), roll-bend specific parts of the metal bar, thereby achieving continuous and efficient forming operations.

[0004] However, in actual production processes, especially for new energy battery connectors with extremely high surface quality requirements, the aforementioned existing technologies have the following technical defects: During rolling, slitting, coiling, and conveying, the surface of flat metal busbars (whether tin-plated or bare steel) easily absorbs dust, oil, or residues from previous processes (such as particles not cleaned after laser peeling). Furthermore, friction between the material and guide components during conveying may also generate minute amounts of metal debris. These tiny surface deposits are carried into the contact interface between the bending rollers and the metal busbar when entering the bending station. During the bending process, the bending rollers apply significant pressure to cause plastic deformation of the metal busbar. If any tiny foreign objects (such as hard particles, detached plating debris, or sticky contaminants) are present on the surface of the metal busbar, they will be pressed into the softer substrate under the immense pressure, forming indentations, pits, or scratches. This damage not only destroys the protective layers (such as tin plating or passivation films) on the busbar surface, affecting its corrosion resistance, but more seriously, in the subsequent laser stripping process, these mechanically damaged areas will lead to uneven laser absorption, thus affecting the stripping accuracy and insulation layer removal effect. Even after laser stripping, these indentations may become stress concentration points, causing microcracks due to thermal expansion and contraction during battery charging and discharging, ultimately leading to busbar breakage or increased contact resistance, severely impacting the safety and lifespan of the battery module.

[0005] In conclusion, we need to improve the aforementioned issues on the production line. Summary of the Invention

A cylinder is provided on the lower surface of the connecting seat. The cylinder is set on one side of the worktable through a support platform at the bottom.

[0010] In the above technical solution, the sliding component further includes a pulley and a screw. The pulley is rotatably sleeved on the lower part of the screw. An open annular cavity is opened inside the inner annular shell. The pulley rolls inside the annular cavity. A limit cap is threaded onto the upper part of the screw. The limit cap is used to limit the rolling of the pulley. A connecting rod is fixedly installed on the upper end of the screw. A wiping cylinder is fixedly connected to the lower surface of the end of the connecting rod away from the screw. An annular tube is fixedly sleeved on the outside of the wiping cylinder.

[0011] In the above technical solution, further, a connecting pipe is installed on one side of each of the multiple ring pipes, and the other end of the multiple connecting pipes is connected to a three-way delivery pipe, with an air pump connected above the three-way delivery pipe.

[0012] In the above technical solution, the clamping mechanism further includes a rectangular groove opened above the inside of the fixed cylinder, and clamping plates are symmetrically slidably installed inside the rectangular groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by incorporating a sliding cylinder chip removal component at the multi-segment bending mechanism, enables comprehensive cleaning of the bending wheel during bending process intervals. Utilizing the scraping action of the wiping cylinder combined with high-pressure airflow driven by an air pump, dust, oil, and metal shavings adhering to the bending wheel surface are thoroughly removed. This prevents foreign matter from being pressed into the metal busbar substrate during bending, causing indentations, pits, or scratches. It effectively protects the protective layer on the metal busbar surface, enhancing its corrosion resistance. Simultaneously, it ensures uniform laser absorption rate during subsequent laser stripping processes, improving stripping accuracy and insulation layer removal effectiveness. Furthermore, it prevents mechanically damaged areas from becoming stress concentration points, preventing micro-cracks, breakage, or increased contact resistance in the connecting busbars during battery charging and discharging, significantly improving the safety and lifespan of the battery module.

[0016] 2. The multi-segment bending mechanism of this invention drives the inner cylinder to rotate outside the fixed cylinder through the driving component. With the intermittent feeding of the rotating material feeding mechanism, it can realize multi-segment and multi-angle continuous bending of metal strips. It can process battery connection strips with complex spatial shapes, meet the compact layout requirements of new energy battery modules, and the clamping mechanism can stably hold the metal strips during the bending process to ensure bending accuracy and forming effect. The bending card is installed on the outside of the inner cylinder by bolts, which is convenient for disassembly and adjustment. The appropriate bending card and bending wheel can be replaced according to the processing requirements of battery connection strips of different specifications and shapes. The equipment has strong adaptability and flexibility, which can meet the diverse production needs of new energy battery connection strips and reduce the cost of equipment replacement and modification.

[0017] 3. In the chip removal component of the present invention, the sliding component is connected by a pulley rolling within the annular cavity of the inner ring shell. With the limiting effect of the limiting cap, the position of the wiping cylinder can be flexibly adjusted according to the assembly position of the bending card seat, so that the wiping cylinder is always precisely fitted with the bending wheel, adapting to different bending processing requirements, improving the versatility and cleaning effect of the cleaning mechanism, and the movement of the overall cleaning structure is linked with the bending mechanism to realize the automation of the cleaning process.

[0018] 4. This invention integrates the entire process of rotary feeding, multi-segment bending, automatic cutting, laser peeling, and automatic material handling. Each mechanism works in conjunction with the controller to achieve automated linkage operation, which greatly improves the processing efficiency of new energy battery steel bars. At the same time, the precise control of each process can ensure the consistency and pass rate of product processing, reduce product loss during the production process, and improve overall production efficiency.

[0023] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0024] like Figures 1-7 The diagram shows a fully automated bending and laser peeling production line for steel bars used in new energy batteries. It includes a worktable 1, a rotating conveyor belt mechanism 5, an X-axis sliding mechanism 12, a cutting mechanism 14, and a laser peeling device 6. A control mechanism is located on one side of the worktable 1. The rotating conveyor belt mechanism 5 is positioned above the worktable 1. Two sets of cutting mechanisms 14 are symmetrically installed outside the rotating conveyor belt mechanism 5 near the discharge port, used to intermittently cut the bent steel bars. A multi-segment bending mechanism is located above the worktable 1 and near the rotating conveyor belt mechanism 5. Each multi-segment bending mechanism includes a drive component and a fixed cylinder 24. The fixed cylinder 24 is externally... The inner cylinder 19 is rotatably sleeved, and the bottom of the fixed cylinder 24 is fixedly installed on the upper surface of the workbench 1. The inner cylinder 19 rotates outside the fixed cylinder 24 in cooperation with the driving component. The inner cylinder 19 is provided with bending brackets 18 at equal intervals along the circumference. The bending brackets 18 are installed outside the inner cylinder 19 by symmetrically installed bolts. A bending wheel 17 is rotatably connected above the bending brackets 18. A clamping mechanism is provided inside the fixed cylinder 24. A cleaning roller chip remover is provided above the driving component to clean the bending wheel 17. The laser peeling device 6 is installed at the other end of the workbench 1 through a support frame mechanism provided on one side. An automatic material handling mechanism is provided on one side of the support frame mechanism. In this embodiment, the rotating conveyor belt mechanism 5 pulls a continuous flat metal strip from the coil and continuously conveys it from the outlet towards the multi-segment bending mechanism. When the front end of the metal strip enters above the fixed cylinder 24 and extends to a predetermined position, the clamping mechanism clamps and fixes the metal strip. Subsequently, the drive unit starts, causing the inner cylinder 19 to rotate around its axis outside the fixed cylinder 24. The bending wheel 17 follows the inner cylinder 19 in a circular motion, applying radial pressure to the metal strip fixed by the clamping plate 27, causing it to undergo plastic deformation along the contact surface of the bending wheel 17. With the intermittent feeding of the rotating conveyor belt mechanism 5 and the control of the rotation direction and angle of the inner cylinder 19, multi-segment, multi-angle continuous bending of the metal strip can be achieved to form the required complex spatial shape. At the same time, the bending holder 18 is detachably installed on the outside of the inner cylinder 19 by bolts, which facilitates the quick replacement or adjustment of the position of the bending wheel 17 according to product specifications, improving the flexibility and changeover efficiency of the production line.

[0025] The driving component includes a rotating shaft 20 and a rotary motor 21. The rotary motor 21 is fixedly installed at the bottom of the worktable 1 and extends to the top of the worktable 1. A gear 22 is fixedly sleeved on the outside of the output shaft of the rotary motor 21. The rotating shaft 20 is rotatably installed inside the worktable 1. A rotating frame 23 is fixedly connected to the upper end of the rotating shaft 20. A gear plate 10 is fixedly installed on the top of the rotating frame 23. The gear plate 10 is fixedly installed at the bottom of the inner cylinder 19. The gear plate 10 is meshed with the gear 22. The chip removal component of the sliding cylinder is arranged above the gear plate 10. In this embodiment, after receiving the bending command, the controller starts the rotary motor 21. The output shaft of the rotary motor 21 drives the gear 22 to rotate. The gear 22 meshes with the gear disk 10 to transmit power to the gear disk 10. The gear disk 10 drives the inner cylinder 19, which is fixedly connected to it, to rotate around its axis outside the fixed cylinder 24. By precisely controlling the rotation angle and direction of the rotary motor 21 by the controller, the inner cylinder 19 can drive the bending wheel 17 to perform multi-angle and multi-segment bending on the metal strip.

[0026] The clamping mechanism includes a rectangular groove opened above the inside of the fixed cylinder 24, and clamping plates 27 are symmetrically slidably installed inside the rectangular groove. The two sets of clamping plates 27 are connected by a bidirectional telescopic rod 26. In this embodiment, after the rotating conveyor belt mechanism 5 transports the metal strip to the preset bending station, the controller controls the bidirectional telescopic rod 26 to move. Both ends of the bidirectional telescopic rod 26 extend outwards simultaneously, pushing the two sets of clamping plates 27 to slide relative to each other in opposite directions within the rectangular groove, gradually approaching and clamping the steel strip. Because the rectangular groove guides and limits the sliding of the clamping plates 27, it ensures that the clamping plates 27 remain parallel and centered throughout the clamping process, thus stably fixing the steel strip at the center of the bending station. After bending, both ends of the bidirectional telescopic rod 26 retract inwards simultaneously, causing the two sets of clamping plates 27 to slide in opposite directions to release the steel strip, allowing the rotating conveyor belt mechanism 5 to perform the next feeding operation.

[0027] The chip removal component includes an outer ring shell 15 and two telescopic sliding rods 16. The lower ends of the two telescopic sliding rods 16 are fixedly mounted on the upper surface of the gear disc 10. The two telescopic sliding rods 16 are symmetrically arranged, and their upper ends are connected to an inner ring shell 32. The inner ring shell 32 is rotatably locked inside the outer ring shell 15. The inner ring shell 32 is equipped with sliding parts corresponding to the cleaning of each set of bending wheels 17. A connecting seat 13 is provided on one side of the outer ring shell 15. A cylinder 25 is provided on the lower surface of the connecting seat 13. The cylinder 25 is mounted on one side of the worktable 1 via a support platform 9 at the bottom. The mounting component includes a pulley 30 and a screw 36. The pulley 30 is rotatably sleeved on the lower part of the screw 36. An open annular cavity is opened inside the inner annular shell 32, and the pulley 30 rolls inside the annular cavity. A limit cap 35 is threaded on the upper part of the screw 36 to limit the rolling of the pulley 30. A connecting rod 31 is fixedly installed on the upper end of the screw 36. A wiping cylinder 29 is fixedly connected to the lower surface of the end of the connecting rod 31 away from the screw 36. An annular tube 33 is fixedly sleeved on the outside of the wiping cylinder 29. Air nozzles 34 are connected at equal intervals along the circumferential direction inside the lower part of the annular tube 33. After one cycle of bending is completed, the controller stops the material feeding of the rotating conveyor belt 5 and simultaneously starts the cylinder 25. The cylinder 25 drives the outer ring shell 15 downward through the connecting seat 13. Since the inner ring shell 32 is connected to the gear plate 10 through the telescopic slide rod 16 and the inner ring shell 32 is rotatably locked inside the outer ring shell 15, when the outer ring shell 15 descends, the inner ring shell 32 descends smoothly along the guide direction of the telescopic slide rod 16, so that the sliding component set inside the inner ring shell 32 contacts the surface of the bending wheel 17. The cylinder 25 can control the outer ring shell 15 to perform reciprocating lifting and lowering motion, driving the sliding component to scrape and clean the surface of the bending wheel 17 multiple times. At the same time, the ring pipe 33 sprays high-pressure gas onto the surface of the bending wheel 17 through the air nozzle 34 to blow away the wiped debris. The telescopic slide rod 16 can play a guiding and limiting role during the lifting and lowering process, ensuring that the inner ring shell 32 always maintains a horizontal posture and its relative position with the gear plate 10 is accurate.

[0028] When the assembly position of the bending holder 18 needs to be adjusted due to changes in product specifications, the operator can manually push the connecting rod 31. The connecting rod 31 drives the pulley 30 to roll within the annular cavity of the inner ring shell 32 via the screw 36, moving the wiping cylinder 29 to the cleaning position corresponding to the bending wheel 17. After adjustment, tighten the limiting cap 35 so that the lower end of the limiting cap 35 abuts against the upper surface of the inner ring shell 32. The screw 36 and the pulley 30 are fixed in position by the threaded locking force, preventing the sliding parts from shifting due to vibration or external force during cleaning.

[0029] Multiple ring pipes 33 are connected to a connecting pipe 28 on one side, and the other end of the multiple connecting pipes 28 is connected to a three-way conveying pipe. An air pump 8 is connected above the three-way conveying pipe. In this embodiment, the high-pressure airflow generated by the air pump 8 is split through the three-way delivery pipe and enters each connecting pipe 28, and then is delivered to the corresponding annular pipe 33. The annular pipe 33 is a ring structure that wraps around the outside of the wiping cylinder 29. The air nozzles 34 are arranged at equal intervals along the circumference of the annular pipe 33, and the spray direction of the air nozzles 34 is towards the circumferential surface of the bending wheel 17. High-pressure gas is sprayed out from multiple air nozzles 34 at the same time, forming a multi-angle airflow around the wiping cylinder 29. While the wiping cylinder 29 is mechanically wiping, the impact force of the high-pressure airflow is used to thoroughly blow away and remove the small particles, oil stains and other contaminants attached to the surface of the bending wheel 17 and the wiping cylinder 29, preventing the contaminants from re-adhering during the wiping process.

[0030] The support frame mechanism includes a side frame 3 fixedly installed at the other end of the workbench 1. A mounting base 4 is fixedly connected to one side of the side frame 3. The laser peeling device 6 is located above the mounting base 4. An automatic material handling mechanism is set on one side of the mounting base 4. The automatic material handling mechanism includes a robot arm 7 and a slide 11. The robot arm 7 is installed above the slide 11. A frame is fixedly connected to one side of the mounting base 4. An X-axis sliding mechanism 12 is set above the frame. The X-axis sliding mechanism 12 drives the slide 11 to move the robot arm 7 to slide. The robot arm 7 automatically picks up the bent and cut steel strips and places them on the laser peeling device 6 for peeling. In this embodiment, the laser head of the laser peeling device 6 faces the workpiece station conveyed by the automatic material handling mechanism. The support frame structure independently sets the laser peeling device 6 at the other end of the worktable 1, forming a process isolation from the bending station, avoiding the impact of vibration generated during the bending process on the laser peeling accuracy, and at the same time facilitating the independent debugging and maintenance of the laser peeling device 6; The X-axis sliding mechanism 12 can be driven by a linear guide rail and lead screw module or a linear motor, with the slide block 11 fixedly connected to the moving parts of the X-axis sliding mechanism 12. After the cutting mechanism 14 completes the fixed-length cutting of the bent steel strip, the controller controls the X-axis sliding mechanism 12 to drive the slide block 11 to move along the X-axis to the cutting station. The gripper of the robot arm 7 opens and picks up the cut steel strip workpiece. Subsequently, the X-axis sliding mechanism 12 reverses the direction, driving the slide block 11 to move the robot arm 7 to the processing station of the laser peeling device 6. The robot arm 7 places the steel strip workpiece in the peeling station for laser peeling. After peeling, the robot arm 7 picks up the finished workpiece again and is transported to the unloading area by the X-axis sliding mechanism 12, realizing fully automatic connection of bending, cutting, picking, peeling, and unloading.

[0031] The control mechanism includes a stand 2 fixedly installed on one side of the workbench 1, and a controller fixedly installed on the upper part of the stand 2. In this embodiment, the controller is a programmable logic controller or an industrial control computer, which integrates a control program and is electrically connected to the actuators such as the rotating conveyor belt mechanism 5, the cutting mechanism 14, the laser peeling device 6, the rotary motor 21, the cylinder 25, the air pump 8, the robot arm 7, and the X-axis sliding mechanism 12 via signal lines.

[0032] Working principle: First, the rotating conveyor belt mechanism 5 starts, pulling the continuous flat steel strip or steel strip from the coil and continuously conveying it from the discharge port towards the multi-segment bending mechanism. When the front end of the steel strip enters above the fixed cylinder 24 and extends to the predetermined position, the clamping mechanism is activated. The bidirectional telescopic rod 26 drives the two sets of clamping plates 27 to slide relative to each other, clamping and fixing the steel strip. Subsequently, the multi-segment bending mechanism starts working. The rotary motor 21 in the drive unit starts, and through the meshing transmission of the gear 22 and the gear plate 10, it drives the gear plate 10 to rotate. The gear plate 10 is fixedly connected to the bottom of the inner cylinder 19, so the inner cylinder 19 rotates around its axis outside the fixed cylinder 24. Multiple bending holders 18 are evenly arranged along the circumference of the inner cylinder 19, and a bending wheel 17 is rotatably connected above each bending holder 18. When the inner cylinder 19 rotates, the bending wheel 17 follows the inner cylinder 19 in a circular motion, applying radial pressure to the steel strip that has been fixed by the clamping plate 27, causing it to undergo plastic deformation along the contact surface of the bending wheel 17, thereby achieving the first bending. After the first bend is completed, the rotating conveyor belt mechanism 5 operates again, conveying the steel strip forward a distance according to the preset feed length, so that the next bending section reaches the clamping position of the fixed cylinder 24. The clamping plate 27 clamps the steel strip again, and the inner cylinder 19 rotates in the opposite direction or in the same direction at a certain angle according to the preset second bending angle, driving the bending wheel 17 to perform the second bend on the steel strip. This cycle repeats, and with the intermittent feed of the rotating conveyor belt mechanism 5 and the control of the rotation direction and angle of the inner cylinder 19, multi-segment, multi-angle continuous bending of the steel strip can be achieved to form the required complex spatial shape; After the bending process of one section of the steel strip is completed, the X-axis sliding mechanism 12 drives the slide block 11 to move the robot arm 7 to the steel strip. After the robot arm 7 picks up the steel strip, the two sets of symmetrically arranged cutting mechanisms 14 are activated to intermittently cut the bent steel strip, completing the separation of the single-section finished blank. After the cutting is completed, the X-axis sliding mechanism 12 drives the material to the processing station of the laser peeling device 6. The laser peeling device 6 is activated to precisely remove the insulation layer of the designated area of ​​the steel strip with laser, exposing the metal substrate and completing the laser peeling process, realizing the integrated processing of bending and peeling of battery steel strips. After the above processes are completed, the production line enters the cleaning process. At this time, the rotating conveyor belt mechanism 5 stops discharging material. The sliding drum chip removal component is activated, and the cylinder 25 drives the outer ring shell 15 to move downward through the connecting seat 13. Since the inner ring shell 32 is connected to the gear plate 10 through the telescopic sliding rod 16, and the inner ring shell 32 is rotated and locked inside the outer ring shell 15, when the outer ring shell 15 descends, the inner ring shell 32 descends accordingly, so that the wiping cylinder 29 in the sliding component set inside the inner ring shell 32 contacts and stays in contact with the surface of the bending wheel 17. Through reciprocating lifting and scraping, the bending wheel 17 is cleaned, removing dust, oil and metal debris that are picked up during the bending process. At the same time, when the wiping cylinder 29 is cleaning, the air pump 8 is activated, and high-pressure gas is delivered to each ring pipe 33 through the three-way conveying pipe and the connecting pipe 28, and sprayed out from the air nozzle 34 below the ring pipe 33 to blow high-pressure airflow across the surface of the bending wheel 17, completely blowing away the attached substances wiped off from the working area. After cleaning is completed, cylinder 25 resets, the chip removal component of the slide rises and disengages from bending wheel 17, and the cleaning process ends; By setting a roller 30 and a screw 36 at the inner ring shell 32, the bending holder 18 can be used in different assembly positions. After the assembly position of the bending holder 18 is adjusted, the roller 30 can be driven to roll inside the inner ring shell 32. After the position of the bending holder 18 is determined, the limit cap 35 is screwed down and pressed against the upper surface of the inner ring shell 32. The movement of the limit roller 30 ensures that the positions of the connecting rod 31 and the wiping cylinder 29 are precisely aligned with the bending wheel 17.
