Description

Technical Field

[0001] This invention relates to the field of cutting device technology for lithium-ion battery production, specifically a cutting device for lithium-ion battery production. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery that works by moving lithium ions between the positive and negative electrodes. They generally use materials containing lithium as electrodes and are representative of modern high-performance batteries. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. However, true lithium batteries are rarely used in everyday electronic products due to their high risk. Existing lithium-ion battery cutting devices generate a large amount of metal dust and debris during cutting. The dust is carried around by the airflow generated by the rapidly rotating cutting blade, while a large amount of debris remains on the cutting table. This results in a large amount of debris remaining on the cutting table after each cutting operation, which requires the user to remove the debris before the next piece of material can be cut, which is very troublesome.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In this invention, the L-shaped plate moves during the movement of the connecting plate, which in turn moves the connecting sleeve. The movement of the connecting sleeve moves the fixing plate, which in turn moves the rotating shaft. The movement of the rotating shaft moves the gear. Because the gear meshes with the rack, the gear rotates under force, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft drives the cleaning roller to rotate, so that the cleaning roller moves and rotates in the same direction as the cutting machine, thereby cleaning the debris generated during cutting from the cutting table and preventing the debris from adhering to the cutting table. 2. In this invention, by providing a connecting sleeve, a slot, a block, and a spring, the L-shaped plate can move a certain distance relative to the connecting sleeve. This ensures that after the L-shaped plate is moved upward by the connecting plate, the connecting sleeve will not move upward under the gravity of the fixed block, the rotating shaft, the cleaning roller, and the gear. Instead, the spring is stretched, so that the gear still meshes with the rack. 3. In this invention, the exhaust fan discharges air from the air outlet, and the air enters the jet head through the second corrugated pipe. Then it blows towards the cleaning roller and the cutting table, scattering the debris on the cleaning roller and the cutting table. At this time, the exhaust fan sucks the scattered debris into the recycling box through the duct and the first slag suction head. The exhaust fan also sucks the metal dust generated during cutting into the recycling box through the first corrugated pipe and the second slag suction head. 4. In this invention, an airflow carrying debris and metal dust passes through a perforated wire mesh and a filter screen in sequence. The perforated wire mesh blocks the debris and large particles, while the filter screen blocks the metal dust, thus preventing the debris and metal dust from entering the exhaust fan.

The second threaded rod 517 is open to the communication groove. The bearing passes through the inner wall of the T-slot 516. The bottom of the T-block 519 is fixedly installed with a cutting machine 518. Rotating the second threaded rod 517 drives the T-block 519 to move back and forth, which in turn drives the cutting machine 518 to move, so that the cutting machine 518 is aligned with the cutting position. Activating the electric telescopic rod 514 drives the connecting plate 515 to move down, which in turn drives the T-block 519 and the cutting machine 518 to move down, so that the cutting machine 518 moves down and contacts the material to be cut. Activating the forward and reverse motor 511 drives the first threaded rod 513 to rotate, which causes the moving block 512 to move to the left or right, which in turn drives the electric telescopic rod 514, the connecting plate 515, the T-block 519, and the cutting machine 518 to move and cut. The cleaning unit 52 includes an L-shaped plate 521. The top end of the L-shaped plate 521 is fixedly connected to the outer right side wall of the movable plate 512.

The bottom of the rack 532 is fixedly connected to the inner outer wall of the bottom of the U-shaped frame 4. A slot 526, a clip 527, and a spring 528 are provided to make the L-shaped frame 4 rotate. Plate 521 can move a certain distance relative to connecting sleeve 522 to ensure that after L-shaped plate 521 is moved upward by connecting plate 515, connecting sleeve 522 will not move upward under the gravity of fixed block 524, rotating shaft 525, cleaning roller 523, and gear 531. Instead, it will stretch spring 528 so that gear 531 will still mesh with rack 532. During the movement of connecting plate 515, L-shaped plate 521 will move, which in turn will move connecting sleeve 522. The movement of connecting sleeve 522 will move fixed plate 524, which in turn will move rotating shaft 525. The movement of rotating shaft 525 will move gear 531. Because gear 531 meshes with rack 532, gear 531 will rotate under force, which will in turn rotate rotating shaft 525. The rotation of rotating shaft 525 will rotate cleaning roller 523, so that cleaning roller 523 moves and rotates in the same direction as cutting machine 518, cleaning the debris generated by cutting from cutting table 3 and preventing debris from adhering to cutting table 3.The slag suction unit 54 includes a first slag suction head 542, a second slag suction head 543, and an exhaust fan 544. The outer wall of the first slag suction head 542 is fixedly connected to the side outer wall of the cutting table 3.

The bottom end of the conduit 541 is connected to a recovery box 545. The inner wall of the recovery box 545 is connected to the air inlet of the exhaust fan 544 through a vent pipe. The bottom of the exhaust fan 544 is fixedly connected to the top of the support plate 2. The bottom of the recovery box 545 is fixedly connected to the top of the support plate 2. A first corrugated pipe 546 is connected to the inner wall of the recovery box 545. (The text then abruptly shifts to a slag blowing unit.) 55 includes a jet head 551, the outer walls of the front and rear ends of the jet head 551 are fixedly connected to the outer wall of the connecting sleeve 522, and the inner wall of the jet head 551 is connected to a second corrugated pipe 552. The bottom end of the second corrugated pipe 552 is connected to the air outlet of the exhaust fan 544. Two first suction heads 542 are provided, located on the front and rear sides of the cutting table 3 respectively. The opening of the first suction head 542 faces the cutting table 3 to suck up the slag on the cutting table 3. The opening of the second suction head 543 faces the cutting machine 518 to suck up the metal dust generated by the cutting machine 518. The first corrugated pipe 546 is set so that the second suction head 543 remains connected to the recycling box 545 when it is driven by the cutting machine 518. The second corrugated pipe 552 is set so that the jet head 543 can be connected to the recycling box 545. When head 551 is driven by connecting sleeve 522, it remains connected to the air outlet of exhaust fan 544. Exhaust fan 544 discharges air from the air outlet, and the air enters jet head 551 through second corrugated pipe 552, and then blows onto cleaning roller 523 and cutting table 3, scattering the debris on cleaning roller 523 and cutting table 3. At this time, exhaust fan 544 sucks the scattered debris into recycling box 545 through duct 541 and first suction head 542. Exhaust fan 544 also sucks metal dust generated during cutting into recycling box 545 through first corrugated pipe 546 and second suction head 543. Filter section 56 includes filter screen 561 and perforated wire mesh 562. The outer wall of filter screen 561 is fixedly connected to the inner wall of recycling box 545, and the outer wall of perforated wire mesh 562... Fixedly connected to the inner wall of the recycling bin 545, the perforated wire mesh 562 is located to the left of the filter screen 561. Airflow carrying debris and metal dust passes sequentially through the perforated wire mesh 562 and the filter screen 561. The perforated wire mesh 562 intercepts debris and large particles, while the filter screen 561 intercepts metal dust, preventing debris and metal dust from entering the exhaust fan 544. A first access door 6 and a second access door 7 are located at the bottom of the recycling bin 545. The second access door 7 is located to the left of the perforated wire mesh 562 and is used to remove debris and large particles intercepted by the perforated wire mesh 562. The first access door 6 is located between the filter screen 561 and the perforated wire mesh 562 and is used to remove metal dust intercepted by the filter screen 561.

[0018] In use, the cutting device for lithium-ion battery production rotates the second threaded rod 517, causing the T-block 519 to move back and forth, which in turn moves the cutting machine 518, aligning it with the cutting position. Activating the electric telescopic rod 514 moves the connecting plate 515 downwards, which in turn moves the T-block 519 and the cutting machine 518 downwards, bringing the cutting machine 518 into contact with the material to be cut. Activating the forward / reverse motor 511 rotates the first threaded rod 513, causing the moving block 512 to move left or right. The movement of the electric telescopic rod 514, connecting plate 515, T-block 519, and cutting machine 518 causes them to move and cut. During the movement of the connecting plate 515, the L-shaped plate 521 moves, which in turn moves the connecting sleeve 522. The movement of the connecting sleeve 522 causes the fixing plate 524 to move, which in turn moves the rotating shaft 525. The movement of the rotating shaft 525 causes the gear 531 to move. Because the gear 531 meshes with the rack 532, the gear 531 rotates under force, which in turn causes the rotating shaft 525 to rotate. The rotation of shaft 525 drives the cleaning roller 523 to rotate, causing the cleaning roller 523 to move and rotate in the same direction as the cutting machine 518, cleaning the debris generated during cutting from the cutting table 3 and preventing the debris from adhering to the cutting table 3. At the same time as cleaning, the exhaust fan 544 is turned on, and the exhaust fan 544 exhausts air from the air outlet. The air enters the jet head 551 through the second corrugated pipe 552, and then blows it onto the cleaning roller 523 and the cutting table 3, dispersing the debris on the cleaning roller 523 and the cutting table 3. At this time, the exhaust fan 544... 4. The scattered debris is sucked into the recycling bin 545 through the conduit 541 and the first suction head 542. The exhaust fan 544 sucks the metal dust generated during cutting into the recycling bin 545 through the first corrugated pipe 546 and the second suction head 543. The airflow carrying debris and metal dust passes through the perforated wire mesh 562 and the filter screen 561 in sequence. The perforated wire mesh 562 blocks the debris and large particles, and the filter screen 561 blocks the metal dust, preventing debris and metal dust from entering the exhaust fan 544.
