Description

Technical Field

[0001] This utility model relates to the field of roll replacement technology, and in particular to a quick replacement device for electrode foil rolls. Background Technology

[0002] In the production of electrochemical products such as batteries and capacitors, electrode foil materials are typically wound into rolls. After a roll of electrode foil is wound, the production line needs to remove the roll and its winding rod from the winding mechanism and replace it with a new winding rod to continue winding the next roll of electrode foil. Most existing production equipment uses manual methods to complete this replacement process, requiring operators to manually disassemble the roll and install the new winding rod.

[0003] A Chinese patent has been published: an electrode foil cutting device, patent announcement number: CN219173806U. This patent "includes a fixed base, the upper surface of which is provided with a first side plate and a second side plate, the bottom of the first side plate is fixedly disposed on the fixed base, the upper surface of which is fixedly disposed with a slide rail, a slide block is slidably disposed on the slide rail, the bottom of the second side plate is welded to the slide block, and a first servo cylinder is fixedly connected to one side of the slide block, the bottom of the first servo cylinder is fixedly connected to the fixed base through a base."

[0004] While this device uses a first servo cylinder to drive a slide block on a rail, which in turn moves a second side plate, which in turn moves a positioning block on one side, thus allowing for the installation, fixation, or easy disassembly of the electrode foil winding drum, its current limitations are significant. In actual production, as the winding length increases, the finished electrode foil drum becomes quite heavy, often requiring multiple people to handle. This results in high operational intensity, low efficiency, and the lack of a dedicated drum replacement mechanism. Furthermore, manual handling not only increases the workload for production personnel but also poses a significant safety hazard due to the risk of the drum slipping or colliding during transport. Additionally, the time spent on manual drum replacement increases production line downtime, reducing overall production efficiency. Therefore, the existing drum replacement method suffers from inconvenience, inefficiency, and safety issues, and urgently needs improvement. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose a quick-change device for electrode foil rolls, so as to solve the problem that when the winding length of the winding drum continues to increase, the weight of the electrode foil roll after winding is large, which often requires multiple people to work together to complete the handling, resulting in high operational intensity and low efficiency.

[0006] To achieve the above objectives, this utility model provides a quick electrode foil roll replacement device, including a workbench. Support frames are fixedly connected to both sides of the top of the workbench. A fixing plate is fixedly connected to the side wall of the support frame. A servo motor for driving the roll rotation is fixedly connected to the side wall of the fixing plate. A placement rack for supporting the roll is fixedly connected to the side wall of the workbench. A replacement mechanism for replacing the wound roll and placing the empty roll is provided on the side wall of the workbench.

[0007] Preferably, the replacement mechanism includes an electric telescopic rod rotatably connected to the side wall of the workbench, linkage rods rotatably connected to both sides of the workbench, a synchronizing rod rotatably connected between the shafts of the two linkage rods, the synchronizing rod being rotatably connected between the two sides of the workbench via a bearing seat, the two linkage rods having a V-shaped structure, anti-slant plates rotatably connected to both sides of the workbench, and a placement block rotatably connected to the end of the linkage rod and the synchronizing rod away from the electric telescopic rod, the placement block having a placement groove inside, the placement groove having a U-shaped structure, and two rollers for placing the drum rod rotatably connected to the bottom of the inner wall of the placement groove.

[0008] Preferably, the top of the placement rack is fixedly connected to a storage rod for placing the wound-up electrode foil roll, and the storage rod is inclined away from the worktable.

[0009] Preferably, the side wall of the placement rack is fixedly connected to two material changing rods for placing the drum rods. The material changing rods are inclined towards the workbench. A material distributing rod is rotatably connected between the opposite surfaces of the two material changing rods. A plurality of equally spaced and uniformly distributed material distributing blocks are fixedly connected to the outer wall of the material distributing rod. The material distributing blocks are V-shaped. The material distributing rod passes through the outer wall of the material changing rod and is fixedly connected to a trigger block.

[0010] Preferably, the end of the storage rod near the workbench is L-shaped and rotatably connected to a rotating plate.

[0011] Preferably, the side wall of the placement block has an inclined surface. When the placement block rotates towards the placement frame, it will abut against the trigger block and push the trigger block to rotate. The rotation of the trigger block will drive the material distribution rod to rotate. The material distribution rod will drive the material distribution block to rotate. When the material distribution block rotates, it will release the limiting position of the drum in the middle part of the material distribution block.

[0012] Preferably, the top of the placement block is provided with a ramp, and the drum rod on the material changing rod will roll down the inclined material changing rod through the placement block into the placement groove.

[0013] The beneficial effects of this utility model are: This electrode foil roll quick-change device uses an electric telescopic rod to drive a linkage rod, a synchronizing rod, and an anti-slant plate to move in tandem. This ensures that the placement block always faces upwards during rotation, preventing the roll from tilting or slipping. The placement groove, along with rollers, supports and guides both ends of the roll, allowing it to rotate freely in a supported state. Once the rolled-up roll reaches the position of the storage rod and rotating plate, it rolls down automatically for storage, avoiding the high labor intensity and safety risks associated with manual handling. Simultaneously, the inclined surface on the side wall of the placement block pushes a trigger block, causing the material distribution rod and block to rotate, releasing the roll's limiting position and allowing each roll to roll down to the top of the placement block. Guided by the top ramp, it enters the placement groove, enabling the sequential feeding of new rolls. This device achieves rapid roll change, significantly reducing manual intervention, improving production continuity and overall operational efficiency, avoiding collisions caused by manual handling, and enhancing safety during changeover.

[0019] like Figures 1 to 6 As shown, an electrode foil roll quick change device includes a workbench 1. Support frames 2 are fixedly connected to both sides of the top of the workbench 1. Fixing plates 3 are fixedly connected to the side walls of the support frames 2. Servo motors 4 for driving the roll rotation are fixedly connected to the side walls of the fixing plates 3. Placement racks 5 for supporting the roll are fixedly connected to the side walls of the workbench 1. A replacement mechanism for replacing the wound roll and placing empty rolls is provided on the side walls of the workbench 1.

[0020] Further, see attached document. Figures 1 to 6As shown, the replacement mechanism includes an electric telescopic rod 6 rotatably connected to the side wall of the workbench 1. Linkage rods 7 are rotatably connected to both sides of the workbench 1. A synchronizing rod 8 is rotatably connected between the shafts of the two linkage rods 7. The synchronizing rod 8 is rotatably connected between the two sides of the workbench 1 via a bearing seat. The two linkage rods 7 are V-shaped. Anti-slant plates 9 are rotatably connected to both sides of the workbench 1. A placement block 10 is rotatably connected to the end of the linkage rods 7 and the synchronizing rod 8 away from the electric telescopic rod 6. A placement groove 11 is formed inside the placement block 10. The placement groove 11 is U-shaped. The bottom of the inner wall of the placement groove 11 is rotatably connected... Two rollers 12 are connected to the placement frame 5 for placing the winding rod. The top of the placement frame 5 is fixedly connected to a storage rod 14 for placing the wound electrode foil roll. The storage rod 14 is inclined away from the worktable 1. Two material changing rods 15 for placing the winding rod are fixedly connected to the side wall of the placement frame 5. The material changing rods 15 are inclined towards the worktable 1. A material separating rod 16 is rotatably connected between the opposite surfaces of the two material changing rods 15. Multiple material separating blocks 17 are evenly distributed at equal intervals on the outer wall of the material separating rod 16. The material separating blocks 17 are V-shaped. The material separating rod 16 passes through the outer wall of the material changing rod 15 and is fixedly connected to a trigger block 18. When it is necessary to remove the wound-up drum and replace it with a new drum, the drive connection to the drum rod is first released by the servo motor 4. At this time, the electric telescopic rod 6 is in the extended state, which drives the linkage rod 7 and the anti-slant plate 9 to make the placement block 10 stably located at the top of the support frame 2. The drum rod can be supported by the placement groove 11. The roller 12 inside the placement groove 11 ensures that the drum rod can rotate freely in the supported state. Subsequently, the electric telescopic rod 6 begins to retract, driving the linkage rod 7 to rotate towards the placement frame 5. The linkage rod 7 achieves coordinated action on both sides through the synchronous rod 8, driving the placement block 10 to rotate. During this process, the anti-skewing plate 9 rotates synchronously. Through the guidance and restriction of the anti-skewing plate 9, the posture change of the placement block 10 during the rotation is suppressed, so that the top of the placement block 10 is set in the upward direction during the material changing process, preventing the drum rod from tilting or slipping during the rotation. When the placement block 10 rotates to the position of the storage rod 14, the two ends of the drum rod contact the top of the rotating plate 19. With the storage rod 14 tilted to one side, the drum can roll along the rotating plate 19 in the direction away from the worktable 1, realizing the storage of the wound drum. As the electric telescopic rod 6 continues to drive the linkage rod 7 and the synchronous rod 8 to rotate, the inclined surface 13 on the side wall of the placement block 10 will abut against the trigger block 18 and generate relative travel, pushing the trigger block 18 to drive the material distribution rod 16 to rotate. The material distribution rod 16 drives the material distribution block 17 to rotate synchronously to 100°. The roller originally in the middle of the V-shaped groove of the material distribution block 17 will be released from the limiting constraint. Under the action of gravity, only one roller can be allowed to roll down to the top of the placement block 10. Since the top of the placement block 10 is provided with a slope, the roller rod will continue to roll along the slope into the placement groove 11, ensuring that the rollers are fed one by one. The remaining rollers are still limited by the material distribution block 17 and held on the material changing rod 15. At this time, the placement groove 11 stably supports the two ends of the roller rod through the U-shaped structure, and ensures that the roller rod can be smoothly positioned through the bottom roller 12. Then, the electric telescopic rod 6 is started again to extend it. The linkage rod 7 and the anti-sloping plate 9 are driven to rotate, and the placement block 10 gradually returns to the top position of the support frame 2. The new roll bar in slot 11 is reconnected to the output end of servo motor 4 to complete the installation of the empty roll and enter a new winding cycle. Through this workflow, the entire roll replacement process is quick, avoiding manual handling and reducing replacement time by 50%. This effectively solves the problems of high operational intensity, low efficiency, and many safety hazards in the traditional method, while ensuring the stability and continuity of roll replacement and improving the overall operating efficiency of the production line.

[0021] Further, see attached document. Figure 5 As shown, the storage rod 14 is L-shaped at one end near the worktable 1 and is rotatably connected to a rotating plate 19; By designing the end of the storage rod 14 near the worktable 1 as an L-shape and rotatably connecting it to the rotating plate 19, it can guide the drum when it is transferred to the storage rod 14, allowing the drum to roll smoothly along the rotating plate 19 to a direction away from the worktable 1 for storage. At the same time, due to the L-shape of one end of the storage rod 14, the rotating plate 19 will rotate upward, so that the rotating plate 19 will not obstruct the movement trajectory of the drum rod to be replaced placed in the placement block 10.

[0022] Further, see attached document. Figure 5 As shown, the side wall of the placement block 10 is provided with an inclined surface 13. When the placement block 10 rotates towards the placement frame 5, it will abut against the trigger block 18 and push the trigger block 18 to rotate. The rotation of the trigger block 18 will drive the material distribution rod 16 to rotate. The material distribution rod 16 will drive the material distribution block 17 to rotate. When the material distribution block 17 rotates, it will release the limit of the drum in the middle part of the material distribution block 17. By creating an inclined surface 13 on the side wall of the placement block 10, when the placement block 10 rotates towards the placement frame 5, the inclined surface 13 can abut against the trigger block 18 and push the trigger block 18 to rotate, thereby driving the material distribution rod 16 and the material distribution block 17 to rotate synchronously. This allows the drum, which was originally located in the middle of the material distribution block 17, to be released from its limit and smoothly released. This design achieves automatic control of the drum release, ensuring that the drums fall one by one in sequence, avoiding the accumulation or collision caused by multiple drums rolling down at the same time, and improving the safety and reliability of material supply.

[0023] Further, see attached document. Figure 3 As shown, the top of the placement block 10 is provided with a ramp, and the drum rod on the material changing rod 15 will roll down the inclined material changing rod 15 through the placement block 10 into the placement groove 11. By setting a ramp at the top of the placement block 10, the drum rod on the material changing rod 15 can automatically roll along the inclined material changing rod 15 under the action of gravity, and smoothly roll down into the placement groove 11 through the top ramp of the placement block 10. This design utilizes the principle of inclined guidance and gravity conveying to realize the automatic transition and precise positioning of the drum rod, avoid manual intervention, improve the automation level of the drum changing process, and ensure that the drum rod can accurately fall into the placement groove 11, thereby improving the changing efficiency and operational stability.
