Description

Technical Field

[0001] This invention belongs to the field of electrode production, specifically a hinged sheet lifting and waste rejection mechanism. Background Technology

[0002] There are two main methods for manufacturing lithium-ion batteries: winding and stacking. During the early stages of production, electrodes may develop defects such as pores, foreign matter cavities, exposed foil, and uneven coating thickness. Defective electrodes can lead to performance and safety risks in the battery. Defective electrodes are inspected after stacking to check for their presence in the cell. If a defective electrode is found, the entire cell is discarded. However, the following defects still exist:

[0003] The typical method used by waste removal organizations is to step on the metal and move it straight up and down. This can easily cause secondary damage to the damaged electrode sheets, making it difficult for staff to determine the source of the damage and affecting their judgment. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In this invention, the lifting block moves up and down by rotating the first rotating plate and the second rotating plate under the action of the following connecting block. When the eccentric wheel rotates to the low point, the lifting block falls down and the broken electrode is forcibly broken by the lifting block. After the broken electrode is removed, the lifting block returns to the high point by the eccentric wheel. The lifting block is then retracted and the good electrode is transported normally, avoiding secondary damage to the electrode tab and ensuring the success of the rejection to a greater extent.

[0018] (2) The invention has a coating on the end of the lifting block and a guide at the end, which can better position the damaged electrode tabs and guide them into the material box along the surface of the lifting block. At the same time, the mounting base can be adjusted back and forth, which makes it easier to adjust the angle of the lifting block and improve the success rate of lifting.

[0019] (3) The invention disengages the locking rod from the locking slot, allowing the screw to rotate. When the electromagnet is energized, it attracts the magnetic block and drives the sliding plate to move. A part of the sliding plate is locked into the second sliding groove on the insertion rod, thereby driving the mounting block to move outward, thus adjusting the position of the lifting block and facilitating the lifting block to remove the tabs.

[0020] (4) When the invention is connected to the slot by the clip rod, the screw fixation has a fixing effect on the slide plate. When the electromagnet is turned on, it attracts the magnetic block and drives the inner plate to move towards the lifting block. Since the side of the slide plate close to the lifting block is in close contact with the inner wall of the second slide groove close to the lifting block, the inner plate moves outward and drives the pushing block to move outward, generating a forward pushing force on the lifting block, thereby improving the vacuum breaking force and improving the electrode tab removal effect.

[0036] The electrode removal assembly 2 includes a support frame 201 mounted on one end of a base plate 1. A fixing plate 202 is mounted on the top of the support frame 201. A motor 203 is mounted on one side of the fixing plate 202. A first pulley 204 is mounted on the output shaft of the motor 203. The first pulley 204 is located on the side of the fixing plate 202 away from the motor 203. A belt 206 is provided below the first pulley 204 and is rotatably mounted on the fixing plate 202. A second pulley 205 is mounted on the outer side of the first pulley 204 and the belt 206. An eccentric wheel 207 is mounted on the side of the belt 206 away from the fixing plate 202. A connecting block 208 is rotatably mounted on the eccentric wheel 207. A connecting bracket 209 is mounted on the bottom end of the connecting block 208. Foot pedal units 210 are equidistantly mounted on the bottom end of the connecting bracket 209. The foot pedal unit 210 includes two connecting plates 2101. The top ends of the connecting plates 2101 are connected to the connecting bracket 202. 9. Fixed connection: Connecting plate 2101 extends through to the bottom of base plate 1. Two first rotating plates 2102 are rotatably mounted on connecting plate 2101. The two first rotating plates 2102 are symmetrically arranged on the side of the two connecting plates 2101 that are far away from each other. A second rotating plate 2103 is rotatably mounted on the end of the first rotating plate 2102 that is far away from connecting plate 2101. A base block 2104 is mounted on the bottom end of the second rotating plate 2103. A rotating head 2106 is mounted on one end of the base block 2104.

The lifting block 2108 moves up and down under the action of the following connecting block 208 and the rotation of the first rotating plate 2102 and the second rotating plate 2103. When the eccentric wheel 207 rotates to its lowest point, the lifting block 2108 falls, forcibly breaking the vacuum of the damaged electrode. After the damaged electrode is removed, the lifting block 2108 is driven back to its highest point by the eccentric wheel 207. The lifting block 2108 is then retracted, and the good electrode is transported normally, avoiding secondary damage to the electrode tabs and ensuring a higher success rate of rejecting defective electrodes. The lifting block 2108 has a coating at its end and a guide at the end for better positioning, making it easier for the damaged electrode tabs to be guided into the material box 303 along the surface of the lifting block 2108. At the same time, the mounting base 2105 can be adjusted back and forth, which facilitates the angle adjustment of the lifting block 2108 and improves the success rate of removing the electrode.

[0038] The length adjustment component 4 includes a slot 401 formed inside the base block 2104, extending to one end of the base block 2104 near the mounting block 2107.

A first groove 403 is formed on the inner top wall of the slot 401, and a second groove 404 is formed at the top of the rod 402. A sliding plate 405 is installed inside the second groove 404, and the top of the sliding plate 405 is slidably mounted inside the first groove 403. A force-enhancing component 5 is installed inside the sliding plate 405. Guide grooves 407 are symmetrically formed on both sides of the first groove 403, and guide blocks 410 are symmetrically mounted on both sides of the sliding plate 405, slidingly mounted inside the guide grooves 407. In the first guide block 407, a first spring 411 is installed on one side of the guide block 410 near the mounting block 2107. One end of the first spring 411 is fixedly connected to the inner wall of the guide groove 407. A magnetic block 412 is installed on the other guide block 410 near the mounting block 2107. An electromagnet 413 is installed on the inner wall of the guide groove 407 near the mounting block 2107. The electromagnet 413 is magnetically connected to the magnetic block 412. A screw 408 is rotatably installed inside the first slide groove 403. The screw 408 is threadedly connected to the slide plate 405.

A rotating block 409 is rotatably installed inside the belt 206. The rotating block 409 is fixedly connected to one end of the screw 408.

[0039] The fixing unit 415 includes a slot 4151 equally angled on the outer wall of the rotating block 409. Side slots 4152 are symmetrically formed on both sides of the rotating block 409. One end of each side slot 4152 extends to the outer side of the bottom block 2104. A side rod 4153 is movably installed inside the side slot 4152. A locking rod 4157 is installed at the end of the side rod 4153 near the rotating block 406. One end of the locking rod 4157 engages with the slot 4151. Limiting plates 4155 are symmetrically installed at the top and bottom ends of the side rod 4153. The limiting plates 4155 are slidably installed inside the limiting groove 4154. The limiting groove 4154 is symmetrically formed on the inner top and bottom walls of the side slot 4152. A second spring 4156 is installed on the side of the limiting plate 4155 away from the rotating block 406. One end of the second spring 4156 is fixedly connected to the inner wall of the limiting groove 4154. The end of the rod 4153 away from the rotating groove 406 is located on the outside of the base block 2104. A rotating seat 4158 is installed on the end of the rod 4153 away from the rotating groove 406. A pressing plate 4159 is rotatably installed on the rotating seat 4158.

The locking rod 4157 is disengaged from the locking groove 4151. The screw 408 can rotate. When the electromagnet 413 is energized, it attracts the magnetic block 412, causing the sliding plate 405 to move. A part of the sliding plate 405 is inserted into the second sliding groove 404 on the insert rod 402, thereby causing the mounting block 2107 to move outward, thereby adjusting the position of the lifting block 2108, which facilitates the lifting block 2108 to remove the tabs.

[0040] The force-enhancing component 5 includes an internal groove 502 formed inside the slide plate 405. A rod groove 503 is formed on the side of the internal groove 502 near the mounting block 2107, located on the guide block 410 with the magnet 412. A block groove 504 is formed on the side of the internal groove 502 near the mounting block 2107, located at one end of the slide plate 405 inside the second slide groove 404. An internal plate 505 is movably installed inside the internal groove 502. A connecting rod 506 is installed on the side of the internal plate 505 near the mounting block 2107, movably installed inside the rod groove 503, and fixedly connected to the magnet 412. A pushing block 507 is installed on the side of the internal plate 505 near the mounting block 2107, located inside the block groove 504. A fourth spring 508 is symmetrically installed on the side of the internal plate 505 near the mounting block 2107. One end of the spring 508 is fixedly connected to the inner wall of the inner groove 502. A third spring 501 is installed on the side of the slide plate 405 away from the mounting block 2107. One end of the third spring 501 is fixedly connected to the inner wall of the second slide groove 404. The side of the slide plate 405 near the mounting block 2107 contacts the inner wall of the second slide groove 404 near the mounting block 2107. When the locking rod 4157 is engaged with the locking groove 4151, the screw 408 fixes the slide plate 405. When the electromagnet 413 is turned on, it attracts the magnetic block 412, causing the inner plate 505 to move towards the lifting block 2108. Since the side of the slide plate 405 near the lifting block 2108 is in close contact with the inner wall of the second slide groove 404 near the lifting block 2108, the inner plate 505 moves outward, causing the pushing block 507 to move outward, generating a forward pushing force on the lifting block 2108, thereby increasing the vacuum breaking force and improving the electrode tab removal effect.

[0041] Working Principle: In use, the mounting base 2105 is fixed on the vacuum conveying platform. After the motor 203 is turned on, it drives the first pulley 204 to rotate, which in turn drives the belt 206 to rotate through the second pulley 205, causing the connecting block 208 to rotate. This causes the connecting plate 2101 to move up and down reciprocally. Under the action of the connecting block 208 rotating, the lifting block 2108 moves up and down through the rotation of the first rotating plate 2102 and the second rotating plate 2103. When the eccentric wheel 207 rotates to the lowest point, the lifting block 2108 falls, and the damaged electrode is forcibly broken from the vacuum. The end of the lifting block 2108 is coated and has a guide for better positioning. The electrode is guided into the material box 303 along the surface of the lifting block 2108. After the damaged electrode is removed, the lifting block 2108 is driven back to the highest point by the eccentric wheel 207, and the lifting block 2108 is retracted, allowing the good electrode to be transported normally. To ensure compatibility with products of different specifications, the mounting base 2105 can be adjusted forward and backward, and the lifting block 2108 can be adjusted at an angle to achieve successful lifting of the film.

[0042] During use, when the position of the lifting block 2108 needs to be adjusted forward, the operator presses the pressing plate 4159, causing the pressing plate 4159 to rotate around the fixed base 41511, thereby pulling the side rod 4153 outward, causing the locking rod 4157 to disengage from the locking groove 4151, allowing the screw 408 to rotate. Subsequently, the electromagnet 413 is energized to generate an attraction force on the magnetic block 412, thereby driving the slide plate 405 to move. A part of the slide plate 405 is inserted into the second sliding groove 404 on the insertion rod 402, thereby driving the mounting block 2107 to move outward, thereby adjusting the position of the lifting block 2108, making it convenient for the lifting block 2108 to remove the electrode tabs. After the adjustment is completed, the pressing plate 4159 is released, causing the side rod 4153 to move back under the elastic force of the second spring 4156, causing the locking rod 4157 to engage in the side groove 4152 to fix the screw 408.

[0043] When the downward vacuum breaking force of the lifting block 2108 is insufficient, the electromagnet 413 is activated, which attracts the magnetic block 412, thereby driving the internal plate 505 to move towards the lifting block 2108. Since the sliding plate 405 is slidably set in the second slide groove 404, and the side of the sliding plate 405 near the lifting block 2108 is in close contact with the inner wall of the second slide groove 404 near the lifting block 2108, after the internal plate 505 moves outward, the pushing block 507 moves outward, generating a forward pushing force on the lifting block 2108, thereby increasing the vacuum breaking force and improving the electrode tab removal effect.
