Description

Technical Field

[0001] This invention relates to the field of electrode processing equipment, and more specifically, to an electrode rewinding and cutting device. Background Technology

[0002] During electrode feeding, when the electrode roll is almost used up, a new electrode roll needs to be replaced, and the old and new electrodes need to be connected. At this time, the old electrode needs to be cut and the material strip needs to be connected to the new electrode to ensure continuous electrode feeding. Currently, some technologies require manual connection after stopping the machine when changing and cutting the old and new electrode rolls. The few automatic roll-changing machines mostly adsorb the electrode, then cut the old electrode through a shearing mechanism, and then connect the old and new electrode through a transfer mechanism. The various mechanisms are set up in the order of adsorption, shearing, and connection, which makes the overall equipment occupy a large space and has low flexibility. For example, a currently disclosed automatic electrode changing device includes a substrate. A main material roll mechanism and a backup material roll mechanism are installed on both sides of the substrate, respectively. Two rows of rollers are installed in the middle of the substrate to allow the electrode to suspend freely. A left-side adsorption and positioning mechanism and a right-side adsorption and positioning mechanism are installed on the upper part of the substrate to adsorb the upper side of the exported electrode. A left-side adsorption and positioning mechanism and a right-side adsorption and positioning mechanism are installed on the lower part of the substrate to adsorb the lower side of the exported electrode. An electrode cutting mechanism is installed on the substrate between the right-side and right-side adsorption and positioning mechanisms to simultaneously cut the electrode from the middle. A left-side electrode transfer mechanism and a right-side electrode transfer mechanism are also installed on the corresponding sides of the substrate to attach the beginnings of new electrode pieces to the ends of the currently running electrode. A main waste material winding mechanism and a backup waste material winding mechanism are installed on the top side of the substrate for winding and recovering the waste material from the beginning of the new electrode piece. The adsorption positioning mechanism, electrode shearing mechanism, and transfer mechanism are arranged in sequence according to the adsorption, shearing, and receiving processes. The overall equipment occupies a large space and has low flexibility. Summary of the Invention

[0003] To overcome the problem in the aforementioned background art where the adsorption positioning mechanism, electrode shearing mechanism, and transfer mechanism are arranged sequentially according to the adsorption, shearing, and receiving processes, resulting in a large overall equipment footprint, this invention provides an electrode rewinding and cutting device.

[0007] Preferably, the reset element is a spring, with one end of the spring connected to the cutter and the other end connected to the inner wall of the second housing.

[0008] Furthermore, the frame is provided with a guide rail, and the first drive assembly and the second drive assembly are slidably connected to both ends of the guide rail. The first drive assembly includes a first cylinder, a first slider, and a first drive gear for driving the first swing arm to swing. The first slider is slidably connected to the guide rail, and the side of the first slider facing away from the first swing arm is connected to the piston rod end of the first cylinder. The extension and retraction direction of the first cylinder is parallel to the guide rail. The side of the first slider near the first swing arm is provided with teeth that match the first drive gear.

The first suction cup and the second suction cup are arranged opposite to each other and can fit together.

[0009] Furthermore, the second drive assembly includes a second cylinder, a second slider, and a second drive gear for driving the second swing arm to swing.

[0013] Preferably, both the first shell and the second shell are cuboid structures.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] This invention improves the space utilization of the equipment by integrating the cutting assembly and the electrode adsorption assembly into a single suction cup, making the equipment more streamlined and ingenious, and facilitating its layout in the workshop. Furthermore, since the first suction cup has a first adsorption part and a second adsorption part for bonding, and the second suction cup has a third adsorption part for bonding, adsorption and bonding can be switched simply by pushing the cylinder to rotate the first and second suction cups. There is no need to set up an additional conversion and splicing station. It is equivalent to cleverly integrating adsorption, cutting, and bonding into one whole, maximizing the space utilization of the equipment and making the roll switching more flexible.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] This embodiment provides an electrode changing and cutting device, including a frame 100, a first swing arm 31, a second swing arm 32, a first drive assembly 40 for driving the first swing arm 31 to swing, a second drive assembly 50 for driving the second swing arm 32 to swing, and a first suction cup 10 and a second suction cup 20 that are arranged opposite to each other and can fit together. The first drive assembly 40 and the second drive assembly 50 are located on opposite sides of the frame. The first drive assembly 40 is connected to one end of the first swing arm 31, and the first suction cup 10 is connected to the other end of the first swing arm 31. The second drive assembly 50 is connected to one end of the second swing arm 32, and the second suction cup 20 is connected to the other end of the second swing arm 32. The first swing arm 31 is also provided with a first flipping drive assembly 70 for driving the first suction cup 10 to flip, and the second swing arm 32 is also provided with a second flipping drive assembly 80 for driving the second suction cup 20 to flip.

[0028] In this embodiment, the first suction cup 10 includes a first housing 11 and a first adsorption part 12 located on one side of the first housing 11. A second adsorption part 13 is also provided on the side of the housing adjacent to the first adsorption part 12. A first roller 14 is provided at the corner of the first adsorption part 12 and the second adsorption part 13. The second suction cup 20 includes a second housing 21 and a cutter assembly located inside the second housing 21. The side of the second housing 21 opposite to the first adsorption part 12 is defined as the cutter surface. A cutter opening 28 for the cutter assembly to extend or retract is provided in the middle of the cutter surface. A second roller 23 is provided on one side of the cutter 24 on the cutter surface, and a plurality of suction cup fixing plates 27 that cooperate with the first adsorption part 12 are provided on the other side. A third adsorption part 22 that cooperates with the second adsorption part 13 is provided on the side of the second housing 21 adjacent to the cutter surface. Thus, the first guide roller 14 and the second guide roller 23 are set to facilitate the feeding of the electrode sheet, allowing it to smoothly enter the working area of ​​the suction cup. In actual use, the suction cup assembly in this embodiment first uses the first adsorption part 12 on the first suction cup 10 and the adsorption fixing plate on the second suction cup 20 to adsorb and clamp the new electrode sheet. The new electrode sheet is then cut by the cutting blade assembly hidden inside the second housing 21. After the cutting blade cuts the electrode sheet, at the same time, the first adsorption part 12 on the first suction cup 10 adsorbs the new electrode sheet onto the first suction cup through negative pressure. The first suction cup 10 and the second suction cup 20 move separately from each other and are both moved by the external conveying mechanism (not shown) to the position of the head of the old electrode sheet. The first suction cup 10 moves to bring the first adsorption part 12 close to the old electrode sheet. The second suction cup 20 moves. Under external force, the second suction cup rotates 90°, aligning the third suction part 22 (with pre-applied adhesive tape) with the new and old electrode sheets. The second suction cup 20 moves towards the first suction cup 10 to a closed position, adhering the new and old electrode sheets. The second suction cup 20 remains firmly attached, holding the adhesive tape and electrode sheets. The first suction cup 10 is then removed, rotated 90° under external force, aligning the second suction part 13 (with pre-applied adhesive tape) with the new and old electrode sheets. The first suction cup 10 moves towards the second suction cup 20 to a closed position, adhering the new and old electrode sheets, thus completing the automatic bonding of the new and old electrode sheet rolls. After complete bonding, the first suction cup 10 and the second suction cup 20 separate, and the bonded electrode sheets proceed to the next step.

[0029] In this embodiment, the cutter assembly includes a cutter 24 that can extend or retract along the cutter opening 28 and a pneumatic piston for extending the cutter 24. The pneumatic piston is connected to an air inlet pipe 25. Reset members 26 for retracting the cutter 24 are also connected to both sides of the cutter 24. In this embodiment, the reset member 26 is a spring, with one end connected to the cutter 24 and the other end connected to the inner wall of the second housing 21. Both the first housing 11 and the second housing 21 are cuboid structures. Thus, the air inlet pipe 25 connects to the air intake device, driving the pneumatic piston to move the cutter 24 forward to cut the electrode. When retraction is required, the cutting air pressure is provided by the spring to retract the cutter 24.

[0030] In this embodiment, a guide rail 60 is provided on the frame. The first drive assembly 40 and the second drive assembly 50 are slidably connected to both ends of the guide rail 60. The first drive assembly 40 includes a first cylinder 41, a first slider 42, and a first drive gear 43 for driving the first swing arm 31 to swing. The first slider 42 is slidably connected to the guide rail 60. The side of the first slider 42 facing away from the first swing arm 31 is connected to the end of the piston rod of the first cylinder 41. The extension and retraction direction of the first cylinder 41 is parallel to the guide rail 60. The side of the first slider 42 near the first swing arm 31 is provided with teeth that match the first drive gear 43. The first drive gear 43 meshes with the first slider 42 and is installed at the end of the first swing arm 31. The first suction cup 10 and the second suction cup 20 are arranged opposite to each other and can fit together; the second drive assembly 50 includes a second cylinder 51, a second slider 52 and a second drive gear 53 for driving the second swing arm 32 to swing. The second slider 52 is slidably connected to the guide rail 60. The side of the second slider 52 facing away from the second swing arm 32 is connected to the piston rod end of the second cylinder 51. The extension and retraction direction of the second cylinder 51 is parallel to the guide rail 60. The side of the second slider 52 near the second swing arm 32 is provided with teeth that match the second drive gear 53. The second drive gear 53 meshes with the second slider 52 and is installed at the end of the second swing arm 32. The teeth on the first slider 42 and the second slider 52 are distributed in a straight line.

[0031] In this embodiment, the first flip drive assembly 70 includes a third cylinder 71, a first crank rocker arm 72, and a first rotating shaft connected to the outer wall of the first suction cup 10. One end of the first crank rocker arm 72 is connected to the piston rod end of the third cylinder 71, and the other end is connected to the first rotating shaft. The second flip drive assembly 80 includes a fourth cylinder 81, a second crank rocker arm 82, and a second rotating shaft connected to the outer wall of the second suction cup 20. One end of the second crank rocker arm 82 is connected to the piston rod end of the fourth cylinder 81, and the other end is connected to the second rotating shaft.

[0032] The working principle of this embodiment is as follows: The structures on both sides of the frame are basically symmetrical. The first swing arm 31 on the left is used to connect the first suction cup 10, and the second swing arm 32 on the right is used to connect the second suction cup 20. When the first cylinder 41 pushes the first slider 42 to slide on the guide rail 60 along the guide rail 60, the teeth on the top side of the first slider 42 mesh with the first drive gear 43, driving the first drive gear 43 to rotate. The first drive gear 43 is connected to the bottom of the first swing arm 31. The rotation of the first drive gear 43 can synchronously drive the first swing arm 31 to swing, realizing the first... A suction cup 10 moves closer to or further away from the second suction cup 20. A third cylinder 71 on the first swing arm 31 rotates the first suction cup 10 by 90°, switching it from a state where the first suction part 12 faces the second suction cup 20 to a state where the second suction part 13 faces the second suction cup 20. Specifically, one side of one end of the first crank rocker arm 72 is connected to the piston rod of the third cylinder 71, and the other side is connected to the first rotating shaft. The third cylinder 71 pushes the first crank rocker arm 72 to rotate, simultaneously rotating the first rotating shaft by 90°, thereby causing the first suction cup 10 to rotate by 90°. Similarly, when the second cylinder 51 pushes the second slider 52 to slide, it can cause the second swing arm 32 to swing, thereby causing the second suction cup 20 to move closer to or further away from the first suction cup 10. When the fourth cylinder 81 extends, it can cause the second suction cup 20 to rotate by 90°.

[0033] During the electrode rewinding and cutting process, the first cylinder 41 and the second cylinder 51 extend, causing the first suction part 12 on the first suction cup 10 and the suction fixing plate on the second suction cup 20 to come into contact, adsorbing and clamping the new electrode. The new electrode is then cut by the cutting assembly hidden inside the second housing 21. Simultaneously, the first suction part 12 on the first suction cup 10 uses negative pressure to adsorb the new electrode onto the first suction cup. The first suction cup 10 and the second suction cup 20 move separately via the drive assembly and are both moved to the position of the old electrode head by an external conveying mechanism (not shown). The first suction cup 10 moves to bring the first suction part 12 close to the old electrode, and the second suction cup 20 moves. Driven by the fourth cylinder 81, the second suction cup 20 rotates 90°, aligning the third suction part 22, which has been pre-adhesive-coated, with the new and old electrode sheets. The second suction cup 20 moves towards the first suction cup 10 to a closed position, bonding the new and old electrode sheets. The second suction cup 20 remains firmly attached, holding the adhesive and electrode sheets. The first suction cup 10 is then removed, and under the action of the third cylinder 71, it rotates 90°, aligning the second suction part 13, which has been pre-adhesive-coated, with the new and old electrode sheets. The first suction cup 10 moves towards the second suction cup 20 to a closed position, bonding the new and old electrode sheets, thus completing the automatic bonding of the new and old electrode sheet rolls. After complete bonding, the first suction cup 10 and the second suction cup 20 separate, and the bonded electrode sheets proceed to the next step.

[0034] This embodiment improves the space utilization of the equipment by integrating the cutting assembly and the electrode adsorption assembly into a single suction cup, making the equipment more streamlined and convenient for layout in the workshop. Furthermore, since the first suction cup 10 is provided with a first adsorption part 12 and a second adsorption part 13 that is bonded together, and the second suction cup 20 is provided with a third adsorption part 22 that is bonded together, adsorption and bonding can be switched by simply pushing the cylinder to rotate the first suction cup 10 and the second suction cup 20. There is no need to set up an additional conversion station, which is equivalent to integrating adsorption, cutting, and bonding together, maximizing the space utilization of the equipment.

[0036] This embodiment is similar to Embodiment 1, except that in this embodiment, the elastic element is an elastic rope.

[0037] Example 3

[0038] This embodiment is a further implementation of Embodiment 1. In this embodiment, the maximum swing amplitude of both the first and second swing arms is 0–60°. Those skilled in the art can make adaptive selections based on actual conditions to adjust the maximum swing angle and achieve a more rational spatial layout.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
