Description

Technical Field

[0001] This utility model relates to the field of battery foil processing equipment, and in particular to a double-sided cutting device for battery foil. Background Technology

[0002] According to the patent document with publication number CN220409049U, when the upper die drives the upper cutter and the pressure seat to move downward, the pressure part of the pressure seat first presses the battery foil onto the lower cutter. Then, as the pressure seat continues to descend, the upper cutter and the lower cutter cooperate to cut the battery foil.

[0003] The patent document states that when the upper cutter presses down on the metal foil being cut, a small amount of metal debris or dust may be generated at the foil break. This dust or metal debris may adhere to the inside of the pressure seat. As the upper cutter moves downward, the metal debris or dust may fall onto the foil, affecting the quality of the foil. At the same time, some dust or metal debris may also adhere to the blade surface, which may also affect the flatness of the foil end face during cutting. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-7 As shown, a double-sided cutting device for battery foil includes a frame 5, a limiting mechanism 1 on the top of the frame 5, a cutting mechanism 2 and two cleaning mechanisms 3, the cutting mechanism 2 being located in the middle of the limiting mechanism 1, and the two cleaning mechanisms 3 being located on both sides of the limiting mechanism 1.

[0029] In this embodiment: the limiting mechanism 1 includes a base plate 12, a lower shearing seat 14 is fixed at the top center of the base plate 12, a top plate 11 is provided above the lower shearing seat 14, and four sliding rods 13 are fixed between the top plate 11 and the base plate 12. The four sliding rods 13 at the top of the base plate 12 are used to support and fix the top plate 11, while the lower shearing seat 14 is used to support the battery foil to be cut, and the lower shearing seat 14 cooperates with the cutting mechanism 2 to cut the battery foil.

[0030] In this embodiment: the cutting mechanism 2 includes a sliding plate 21, with two shearing cylinders 26 fixedly mounted on the top of the sliding plate 21, a limiting seat 22 fixedly mounted on the bottom of the sliding plate 21, and cutting shears 24 fixed on both sides of the limiting seat 22. A pressure plate 25 is provided at the bottom of the limiting seat 22, and a guide frame 27 is fixedly mounted on the top of the pressure plate 25. A support spring is sleeved on the outer side of the guide frame 27. A sliding hole for the guide frame 27 to extend is provided at the center of the limiting seat 22, and a notch is provided at the center of the bottom of the limiting seat 22, with the upper end of the support spring fixed inside the notch. Guide holes for sliding on four sliding rods 13 are provided at the corners of the sliding plate 21. A return spring 23 is fixed at the bottom of plate 21 at the position of four guide holes. The fixed part of each shearing cylinder 26 is fixedly connected to the top of the top plate 11, and the telescopic part of each shearing cylinder 26 is fixedly connected to the top of the sliding plate 21. The side of the cutter 24 near the limit seat 22 is in the same plane as the side of the lower shear plate seat 14. The telescopic parts of the two shearing cylinders 26 are extended to push the sliding plate 21 to move downward along the four slide rods 13. The downward movement of the sliding plate 21 drives the limit seat 22, the two cutters 24 and the pressure plate 25 to move downward synchronously. As the sliding plate 21 moves downward, the pressure plate 25 first pushes the battery foil towards As the lower shear plate 14 moves to the top, and the pressure plate 25 pushes the battery foil against the top of the lower shear plate 14, the guide frame 27 on the top of the pressure plate 25 extends upward along the slider of the limiting seat 22. At this time, the support spring on the outside of the guide frame 27 begins to compress, and the pressure plate 25 no longer moves downward with the sliding plate 21. Instead, the sliding plate 21 continues to drive the two cutting blades 24 downward through the limiting seat 22. At this time, the sides of the two cutting blades 24 that are close to each other coincide with the end faces of the two sides of the lower shear plate 14. Then, the two cutting blades 24 begin to cut the battery foil pressed against the top of the lower shear plate 14. After the battery foil is cut... Then, the telescopic parts of the two shearing cylinders 26 drive the sliding plate 21 to move upward along the slide rod 13. At this time, the sliding plate 21 drives the limit seat 22 and the two cutting blades 24 to move upward synchronously. The pressure plate 25 will continue to press against the top of the lower shear plate seat 14 under the action of the support spring. When the support spring is no longer compressed, as the sliding plate 21 continues to move upward, the pressure plate 25 will move upward synchronously under the action of the guide frame 27. During this process, the two cutting blades 24 slowly slide past the two sides of the pressure plate 25, and then the side of the two cutting blades 24 that are close to each other can be scraped and cleaned to remove the dust or metal debris adsorbed by the two cutting blades 24 during cutting.

[0031] In this embodiment: the cleaning mechanism 3 includes a cleaning brush bucket 33. A T-shaped seat is fixed at the upper end of the cleaning brush bucket 33. A first flipping frame 31 and a second flipping frame 32 are hinged to the end of the cleaning brush bucket 33 away from the sliding plate 21. The second flipping frame 32 is located on the side of the first flipping frame 31 near the sliding plate 21. A brush roller 34 is rotatably connected inside the cleaning brush bucket 33. A drive cylinder 35 is hinged to the upper side of the second flipping frame 32. Positioning frames are fixed on both sides of the top plate 11. The upper ends of the second flipping frame 32 and the first flipping frame 31 are hinged to the positioning frames. A support seat is fixed at the bottom of the top plate 11 near the positioning frames. The other end of the drive cylinder 35 is hinged to the lower end of the support seat. A rotary motor 4 for driving the brush roller 34 to rotate is fixedly installed at the front end of the cleaning brush bucket 33. When the sliding plate 21 has been cut multiple times and moved to a position near the top plate 11, the telescopic part of the drive cylinder 35 shortens and pulls... The second rotating frame 32 rotates downwards with its upper end as the center. At this time, the first rotating frame 31 will also rotate along with the second rotating frame 32, so that the cleaning brush bucket 33 is attached to the bottom of the pressure plate 25. Then, the rotating part of the rotating motor 4 drives the brush roller 34 to rotate inside the cleaning brush bucket 33. At this time, the brush roller 34 is used to brush and clean the side of the cutter 24 away from the pressure plate 25, thereby cleaning up the dust or metal debris that may be attached to the side of the cutter 24 away from the pressure plate 25. In addition, at the moment when the cleaning brush bucket 33 is attached to the bottom of the pressure plate 25, the T-shaped seat inside the cleaning brush bucket 33 will hit the cutter 24 on both sides of the pressure plate 25. The cutter 24 will transmit the vibration to the pressure plate 25, and a certain degree of vibration will be generated on the pressure plate 25 and the cutter 24, thereby shaking off the dust that may be attached to the bottom of the pressure plate 25 and the front and rear ends of the cutter 24.

[0032] Working principle: In use, the battery foil to be cut is first fed into the position between the lower shearing plate seat 14 and the pressure plate 25. At this time, the telescopic parts of the two shearing cylinders 26 extend to push the sliding plate 21 downward along the four slide rods 13. The downward movement of the sliding plate 21 drives the limiting seat 22, the two cutting blades 24, and the pressure plate 25 to move downward synchronously. As the sliding plate 21 moves downward, the pressure plate 25 first pushes the battery foil to the top of the lower shearing plate seat 14. After the pressure plate 25 pushes the battery foil against the lower shearing plate... When the pressure plate 25 is on top of the seat 14, the guide frame 27 on the top of the pressure plate 25 will extend upward along the slider of the limit seat 22. At this time, the support spring on the outside of the guide frame 27 begins to compress. Meanwhile, the pressure plate 25 no longer follows the sliding plate 21 to continue moving downward. The sliding plate 21 will continue to drive the two cutting blades 24 to move downward through the limit seat 22. At this time, the side of the two cutting blades 24 that are close to each other coincides with the end faces of both sides of the lower shear plate seat 14. Then the two cutting blades 24 begin to cut the battery foil material pressed on the top of the lower shear plate seat 14.

[0033] After the battery foil is cut, the telescopic parts of the two shearing cylinders 26 drive the sliding plate 21 to move upward along the slide rod 13. At this time, the sliding plate 21 drives the limit seat 22 and the two cutting blades 24 to move upward synchronously. The pressure plate 25 will continue to press against the top of the lower shear plate seat 14 under the action of the support spring. When the support spring is no longer compressed, the pressure plate 25 will move upward synchronously under the drive of the guide frame 27 as the sliding plate 21 continues to move upward. During this process, the two cutting blades 24 slowly slide past the sides of the pressure plate 25, and then the side of the two cutting blades 24 that are close to each other can be scraped and cleaned to remove the dust or metal debris adsorbed by the two cutting blades 24 during cutting.

[0034] After the sliding plate 21 has undergone multiple cuts and moved to a position close to the top plate 11, the telescopic part of the drive cylinder 35 shortens and drives the second flipping frame 32 to flip downwards with its upper end as the center. At this time, the first flipping frame 31 will also flip along with the second flipping frame 32. Then, the two cleaning brush buckets 33 are respectively attached to the bottom sides of the pressure plate 25. Then, the rotating part of the rotary motor 4 drives the brush roller 34 to rotate inside the cleaning brush bucket 33. At this time, the brush roller 34 is used to clean the side of the cutter 24 away from the pressure plate 25. The brushing and cleaning process removes dust or metal shavings that may be attached to the side of the cutting scissors 24 away from the pressure plate 25. In addition, the moment the cleaning brush bucket 33 is attached to the bottom of the pressure plate 25, the T-shaped seat at the top of the cleaning brush bucket 33 will impact the cutting scissors 24 on both sides of the pressure plate 25. The cutting scissors 24 will transmit the vibration to the pressure plate 25, and a certain degree of vibration will be generated on the pressure plate 25 and the cutting scissors 24, thereby shaking off the dust that may be attached to the bottom of the pressure plate 25 and the front and rear ends of the cutting scissors 24.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
