Description
Technical Field
[0001] This utility model belongs to the field of battery production technology, and in particular relates to a cutting device for lithium battery cells. Background Technology
[0002] Lithium-ion battery cells are the most widely used type of modern battery technology, and are widely used in mobile electronic devices, power tools, electric vehicles, energy storage devices and other fields. Lithium-ion battery cells have advantages such as high energy density, long cycle life, light weight and relatively small size, so they have become one of the most mainstream battery types.
[0003] The outer casing of lithium battery cells is generally thin and somewhat brittle. If the cell is not secured during the cutting process, it may be damaged due to vibration or movement. Damaged cells may damage the internal materials of the battery (such as the positive electrode, negative electrode, or electrolyte). Therefore, we propose a cutting device for lithium battery cells. Utility Model Content
[0004] The purpose of this invention is to provide a cutting device for lithium battery cells. By manually rotating the worm gear two, the worm wheel two is driven to rotate.

[0008] Furthermore, the outer wall of the threaded rod penetrates the inner wall of the groove and extends to the outside of the operating table, the outer wall of the threaded rod is rotatably connected to the inner wall of the operating table, and the outer wall of the worm gear is rotatably connected to the inner wall of the operating table.
[0009] Furthermore, the outer wall of the fixing plate is slidably connected to the inner wall of the groove, the outer wall of the clamping plate is slidably connected to the inner wall of the second sliding groove, and the outer wall of the second worm gear is rotatably connected to the inner wall of the fixing plate.

[0012] Furthermore, a spring is fixedly connected to the side of the semicircular block near the fixed block, and the end of the spring away from the semicircular block is fixedly connected to the outer wall of the fixed block. The telescopic rod is located inside the spring.

[0014] Furthermore, the side of the telescopic rod two away from the sliding block is fixedly connected to the inner wall of the groove two, the side of the sliding block near the telescopic rod two is fixedly connected to the spring two, the end of the spring two away from the sliding block is fixedly connected to the inner wall of the groove two, the telescopic rod two is located inside the groove two, and a semi-circular groove block is rotatably connected to the outer wall of the sliding block.
[0015] Furthermore, a limiting plate is fixedly connected to the outer wall of the operating table, and the outer wall of the limiting plate contacts the outer wall of the semi-circular groove block.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model incorporates a clamping plate. First, the battery material is placed in the fixed plate. Then, the worm gear two is manually rotated, causing the worm wheel two to rotate. As the worm wheel two rotates, it also drives the reverse threaded rod to rotate, thus bringing the clamping plates closer together to clamp the battery material. After the battery material is clamped, the worm gear one is manually rotated, which in turn drives the worm wheel one to rotate. As the worm wheel one rotates, it also drives the threaded rod to rotate, thus moving the position of the fixed plate. During the movement, once the portion of the battery material to be cut exceeds the position of the cutter, the rotation of the worm wheel one stops. This mechanism can fix the battery material to be cut, preventing the battery material from shifting due to external forces during the cutting process, which could lead to cutting failure.
[0018] 2. This utility model incorporates a cutter. After the battery material has been moved, the second motor is activated, driving the threaded rod two to move. As the threaded rod two moves downwards, it drives the cutter to move, cutting the battery material. During the downward movement of the cutter, the fixed block moves, which in turn moves the telescopic rod, causing the semi-circular block to move. When the cutter has completely moved downwards, the semi-circular block will engage with the semi-circular groove. During this engagement, the telescopic rod and spring one are compressed, and the reaction force provided by spring one also causes the semi-circular block to engage with the semi-circular groove. Then, the second motor is reversed, driving the threaded rod two to rotate, causing the cutter to move upwards. As the cutter cuts the battery material, the upward movement of the mechanism causes the end of the push plate away from the rotating shaft to move upwards, allowing the cut material to fall into the collection frame below, thus collecting the cut waste.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Limit plate 316 is fixedly connected to the outer wall of operating table 101. The outer wall of limit plate 316 contacts the outer wall of semicircular groove block 315. By setting limit plate 316, the position of semicircular groove block 315 is prevented from being incorrect, so that semicircular block 308 cannot be inserted into semicircular groove block 315.
[0033] One specific application of this embodiment is:
[0034] First, the battery material is placed in the fixing plate 205. Then, the worm gear 211 is manually rotated, causing the worm wheel 210 to rotate. As the worm wheel 210 rotates, it also drives the reverse threaded rod 209 to rotate, causing the clamping plates 208 to move closer together and clamp the battery material. After the battery material is clamped, the first motor 212 is started to rotate the worm gear 204, which in turn drives the worm wheel 203 to rotate. As the worm wheel 203 rotates, it drives the threaded rod 202 to rotate, causing the fixing plate 205 to move. During this movement, once the portion of the battery material to be cut exceeds the position of the cutter 303, the rotation of the worm wheel 203 stops. This mechanism can cut the battery material as needed. To prevent the battery material from shifting due to external forces during the cutting process, thus avoiding cutting failure, the second motor 301 is activated after the battery material has shifted. This drives the threaded rod 302 to move downwards. As the threaded rod 302 moves downwards, it also drives the cutter 303 to move, cutting the battery material. During the downward movement of the cutter 303, the fixing block 305 moves, which in turn moves the telescopic rod 306, thereby moving the semi-circular block 308. When the cutter has completely moved downwards, the semi-circular block 308 will engage with the semi-circular groove 315. During this engagement, the telescopic rod 306 and the spring 307 are compressed, and the reaction force provided by the spring 307... This will also cause the semicircular block 308 to engage with the semicircular groove block 315, and then reverse the second motor 301, driving the threaded rod 302 to rotate, thereby causing the cutter 303 to move upward. As the cutter 303 moves upward, it will drive the fixed block 305 to move upward, thereby driving the telescopic rod 306 to move, and then driving the semicircular block 308 to move. When the semicircular block 308 moves, it will drive the semicircular groove block 315 to move, thereby driving the sliding block 314 to move in the spring 313, squeezing the telescopic rod 312 and the spring 313, thereby causing the push plate 310 to rise on the side away from the rotating shaft 309. At this time, the part cut off above the push plate 310 will fall down the push plate 310 into the receiving part below. Within the frame, it will not interfere with the next cut. When the fixed block 305 rises to a certain height, due to the limitation of the length of the second groove 311, the semi-circular groove locking block 315 cannot move with the fixed block 305. Therefore, the semi-circular block 308 will disengage from the semi-circular groove locking block 315. During the disengagement process, the semi-circular block 308 will squeeze the first spring 307 and the telescopic rod 306. Then, due to the reaction force of the second spring 313, the sliding block 314 will return to its initial position. And due to the presence of the limiting plate 316, the semi-circular groove locking block 315 will also return to its initial position. During the upward process of the cutter 303 after cutting the battery material, this mechanism drives the end of the push plate 310 away from the rotating shaft 309 to move upward.This allows the cut material to fall into the collection box below, completing the collection of the cut waste.
