Description

Technical Field

[0001] This invention relates to the field of cutting machine tool technology, and in particular to a square lithium battery cutting and recycling device. Background Technology

[0002] In recent years, with the gradual scrapping of new energy vehicles, the amount of scrapped power batteries has been increasing. Furthermore, the amount of scrapped power batteries and energy storage batteries is expected to rise rapidly in the next few years, making the recycling and reuse of power lithium batteries an important industry. Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium. Lithium battery recycling methods include wet processes, pyrometallurgical processes, physical processes, and biological processes. Among these, physical remediation recycling is a novel recycling method with high recycling rates and low costs. Physical remediation recycling requires meticulous disassembly of the power lithium battery to extract the positive electrode powder. Subsequently, lithium carbonate is added to the positive electrode powder and then calcined to replenish the missing lithium element. After a high-temperature reaction, lithium iron phosphate material is obtained again.

[0003] However, physical repair and recycling methods require precise disassembly of power lithium batteries, necessitating the separation of the positive and negative electrodes and separators from the cells before subsequent repair processing. Since most existing power lithium batteries are prismatic, the disassembly process requires removing the end caps from both ends of the battery casing and extracting the cells before processing them, thus enabling the cells to be cut and recycled.

[0004] However, during the cutting of square lithium battery casings, the battery feeding mechanism adopts a rigid drive mode with constant speed movement. However, the resistance of the square lithium battery casing during the cutting process is not constant. Due to the large cutting contact area of ​​the circular saw at the starting corner and the other corner at the end of the cutting, the cutting resistance is relatively large. When cutting the middle part of the lithium battery, the area will be smaller, and the resistance will also be smaller. When the cutting resistance suddenly increases, it is easy to cause deformation of the battery casing and the circular saw due to excessive extrusion pressure, and even damage to the internal cells. In severe cases, it may cause short circuit and fire. At the same time, under constant feed speed, the tool does not stay in the hard point area for a long time, and the burrs and curling edges of the casing may be severe, which may affect the efficiency of subsequent cell separation. Summary of the Invention

[0005] The purpose of this invention is to solve the problems raised in the prior art, and to propose a square lithium battery cutting and recycling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a square lithium battery cutting and recycling device, comprising a cutting machine body, the top of the cutting machine body being provided with a guide rail for sliding a movable seat, the bottom of the movable seat being provided with a sliding groove cooperating with the guide rail, and the top of the movable seat being provided with a buffer clamp mechanism. The buffer clamp mechanism includes a first clamping block, a sliding rod slidably connected through the interior of the first clamping block, and a second clamping block slidably connected to the outer wall of one end of the sliding rod. A first tension spring is fixedly connected to the end of the sliding rod located inside the second clamping block, and the end of the first tension spring away from the sliding rod is fixedly connected to the interior of the second clamping block. A telescopic cylinder is fixedly connected to the side wall of the movable seat, and a telescopic rod is slidably connected through the interior of the telescopic cylinder. A filter plate is fixedly connected to the end of the telescopic rod located inside the telescopic cylinder, and a first spring is fixedly connected to one side of the filter plate. The end of the first spring away from the filter plate is fixedly connected to the inner wall of the telescopic cylinder. A cylindrical block is fixedly connected to the outer wall of the end of the sliding rod away from the first tension spring, and the end of the telescopic rod away from the filter plate is fixedly connected to the side wall of the first clamping block.

[0007] Furthermore, a motor drive assembly is fixedly installed inside the cutting machine body, and the output shaft of the motor drive assembly is connected to a circular saw via belt drive.

[0008] Furthermore, the top of the movable seat is provided with a dynamic clamping mechanism, which includes a U-shaped fixing frame, and a gear is rotatably connected to the outer wall of the U-shaped fixing frame. A first rack is fixedly connected to the bottom of the cylindrical block, and the inner wall of the first rack meshes with the inner wall of the gear teeth. A groove is provided on the top of the movable seat, and a second rack is fixedly connected to the inner wall of the groove, and the inner wall of the second rack meshes with the inner wall of the gear teeth.

[0009] Furthermore, the top of the cutting machine body has two through-holes, and the inner walls of both of the two mounting slots are provided with expansion internal support mechanisms.

[0010] Furthermore, the expansion internal support mechanism includes a fixed rod, and a slider is slidably connected to the outer wall of the fixed rod. A second spring is fixedly connected to the side wall of the slider, and the end of the second spring away from the slider is fixedly connected to the inner wall of the mounting groove.

[0011] Furthermore, the top of the slider is fixedly connected to two positioning rods, and the outer walls of the two positioning rods are provided with movable plates. The interior of the movable plates is provided with positioning grooves, and the inner walls of the positioning grooves are slidably connected to the outer walls of the positioning rods. A third spring is fixedly connected to the outer walls of the positioning rods, and the end of the third spring away from the positioning rods is fixedly connected to the inner wall of the movable plates. A connecting block is fixedly connected to one end of each of the two movable plates, and a flip plate is fixedly connected to the end of the movable plates away from the connecting block. A second tension spring is fixedly connected between the two connecting blocks.

[0012] Furthermore, an electric push rod for driving the moving seat to reciprocate linearly is fixedly installed on the top of the cutting machine body, and the output end of the electric push rod is fixedly connected to the side wall of the moving seat.

[0013] Furthermore, the sidewall of the circular saw is fixedly installed on the inner wall of the mounting groove, and the side of the flip plate corresponds to the cutting edge of the circular saw.

[0014] Compared with existing technologies, the above solution has the following advantages: 1. When a square lithium battery is in a fixed state and is in contact with a rotating circular saw for translational cutting, if it encounters a sudden increase in resistance such as the corner of the battery casing or a weld, the first clamping block will overcome the damping of the elastic hydraulic telescopic rod and the force of the first spring, and slide slightly backward along the inner wall of the moving seat. This will automatically slow down the feed speed of the battery relative to the circular saw. The hydraulic damping allows the circular saw to cut through the hard points in a smoother manner. After cutting through the hard points, the spring will automatically reset and the original speed will be restored to continue cutting.

[0015] 2. During the buffering process when the first clamping block slides backward due to excessive cutting resistance, the sliding displacement state triggers the dynamic clamping mechanism, thereby applying additional force to the jaws on both sides of the battery. This causes the clamping force on the battery to increase synchronously with the increase in cutting resistance. When the buffering ends and the first clamping block resets, the increased clamping force is automatically released and returns to the normal level. This achieves instantaneous reinforcement and fixation of the battery during difficult cutting stages, ensuring that the battery will not shift or vibrate under high resistance, thus improving reliability and stability.

[0016] 3. While the circular saw cuts a gap in the outer casing, two combined flip plates are inserted into the cut. Then, the movable plate is squeezed, causing it to slide along the positioning rod and drive the flip plate to flip outward using the lever principle. During the process, the front ends of the two flip plates remain in contact, while the rear ends gradually open, thus forming a continuous stretching force on the side walls inside the cut, increasing the gap in the cut. This physically isolates the side of the circular saw from the inner wall of the cut in the battery casing, eliminating frictional heat and side wear at the source. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order, or relative importance between these entities or operations.

[0021] Example 1, please refer to Figures 1-4A square lithium battery cutting and recycling device includes a cutting body 1. The top of the cutting body 1 is provided with a guide rail for a sliding seat 2. The bottom of the sliding seat 2 is provided with a groove that cooperates with the guide rail. A buffer clamping mechanism 3 is provided on the top of the sliding seat 2. The buffer clamping mechanism 3 includes a first clamping block 301. A sliding rod 302 is slidably connected through the interior of the first clamping block 301. A second clamping block 304 is slidably connected to the outer wall of one end of the sliding rod 302. A first tension spring 303 is fixedly connected to one end of the sliding rod 302 located inside the second clamping block 304. The end of the first tension spring 303 away from the sliding rod 302 is fixedly connected to the second clamping block 304. Inside block 304, a telescopic cylinder 305 is fixedly connected to the side wall of the movable seat 2, and a telescopic rod 306 is slidably connected through the inside of the telescopic cylinder 305. A filter plate 307 is fixedly connected to one end of the telescopic rod 306 inside the telescopic cylinder 305, and a first spring 308 is fixedly connected to one side of the filter plate 307. The end of the first spring 308 away from the filter plate 307 is fixedly connected to the inner wall of the telescopic cylinder 305. A cylindrical block 309 is fixedly connected to the outer wall of the sliding rod 302 away from the first tension spring 303. The end of the telescopic rod 306 away from the filter plate 307 is fixedly connected to the side wall of the first clamping block 301.

[0022] In this embodiment, before cutting the square lithium battery, the operator needs to install and fix the square lithium battery to be cut. First, pull the second clamping block 304 above the moving base 2. Since the position of the first clamping block 301 is restricted by the telescopic rod 306 and cannot move, the second clamping block 304 is pulled, which will cause the first tension spring 303 to be in a stretched state, and apply a pulling force to the second clamping block 304 towards the first clamping block 301. During this process, the positions of the first clamping block 301 and the second clamping block 304 will be relatively far apart. Then, after the battery is placed between them, the electric push rod 7 for driving the moving base 2 to move linearly is fixedly installed on the top of the cutting machine body 1. The output end of the electric push rod 7 is fixedly connected to the side wall of the moving base 2. The side wall of the circular saw 9 is fixedly installed on the inner wall of the mounting groove 5. The side of the flip plate 608 corresponds to the cutting edge of the circular saw 9. The motor drive assembly 8 is fixedly installed inside the cutting machine body 1. The output shaft of the motor drive assembly 8 is connected to the circular saw 9 through belt drive.

[0023] This aligns the end of the outer casing to be cut with the circular saw 9. Then, the second clamping block 304 is released, allowing the battery to be clamped and fixed by the tension of the first tension spring 303. Next, the electric push rod 7 is driven to output power. The electric push rod 7 then starts working, causing the movable seat 2 fixedly connected to its output end to move horizontally. This allows the slide groove at the bottom of the movable seat 2 to slide smoothly along the guide rail at the top of the cutting machine body 1. At the same time, it drives the entire buffer clamping mechanism 3 and the battery it clamps to move towards the rotating circular saw 9. The high-speed rotating circular saw 9 contacts the battery casing, thus starting the cutting work on the battery casing.

[0024] When the circular saw 9 cuts to the starting and ending corners of the battery casing, the cutting resistance increases suddenly due to the large cutting contact area. At this time, the battery transmits the increased resistance to the telescopic rod 306 fixedly connected to it through the first clamping block 301, causing the telescopic rod 306 to move inward into the telescopic cylinder 305 after being subjected to force. At the same time, it drives the filter plate 307 at its end to move. Since the telescopic cylinder 305 is equipped with hydraulic oil, the hydraulic oil passes through the filter holes on the filter plate 307 in a squeezed manner during the movement, generating a damping effect. At the same time, the first spring 308 is compressed. The compressive force generated by the compression of the first spring 308 can provide force for the subsequent reset of the filter plate 307. The above process enables the second clamping block 304 and the first clamping block 301 to drive the battery to produce a slight backward buffer displacement relative to the moving seat 2, thereby automatically slowing down the feed speed of the battery relative to the circular saw 9, allowing the circular saw 9 to cut through the high resistance area in a smoother manner, avoiding tool damage or battery casing deformation caused by forced cutting.

[0025] Specifically, when the square lithium battery is in a fixed state and is in contact with the rotating circular saw 9 for translational cutting, if it encounters a sudden increase in resistance such as the corner of the battery casing or weld seam, the first clamping block 301 will overcome the damping of the elastic hydraulic telescopic rod 306 and the force of the first spring 308, and slide slightly backward along the inner wall of the moving seat 2, thereby automatically slowing down the feed speed of the battery relative to the circular saw 9. The hydraulic damping makes the circular saw 9 cut through the hard point in a smoother manner. After cutting through the hard point, the spring automatically resets and resumes the original speed to continue cutting.

[0026] Furthermore, a dynamic clamping mechanism 4 is provided on the top of the movable seat 2. The dynamic clamping mechanism 4 includes a U-shaped fixing frame 401, and a gear 402 is rotatably connected to the outer wall of the U-shaped fixing frame 401. A first rack 403 is fixedly connected to the bottom of the cylindrical block 309, and the inner wall of the first rack 403 meshes with the inner wall of the gear teeth of the gear 402. A groove 404 is provided on the top of the movable seat 2, and a second rack 405 is fixedly connected to the inner wall of the groove 404. The inner wall of the second rack 405 meshes with the inner wall of the gear teeth of the gear 402.

[0027] Specifically, as the first clamping block 301 moves backward along with the telescopic rod 306, it simultaneously drives the U-shaped fixing frame 401 fixed at its bottom to move backward. Simultaneously, the U-shaped fixing frame 401 drives the gear 402 to move synchronously. Since the second rack 405 is fixedly installed inside the groove 404, the gear 402, meshed with the second rack 405, rotates during the movement. This rotation then drives the first rack 403, meshed with the other side, to move forward. The first rack 403 then drives the cylindrical block 309 to move synchronously. Due to the displacement of the sliding rod 302 connected to the first tension spring 303 at this time, the first tension spring 303 is further... The step stretching process, during which the feed speed of the battery is buffered by the buffer clamping mechanism 3 when the cutting resistance increases, further enhances the clamping force on the battery, ensuring that the battery remains motionless under the impact of the strong cutting force without any displacement or vibration. Afterwards, when the circular saw 9 smoothly passes through the high resistance area and cuts the middle part of the battery shell, the cutting resistance returns to normal. At this time, the compressed first spring 308 releases its elasticity, pushing the telescopic rod 306 and the first clamping block 301 forward to reset, causing the slide rod 302 to slide inward into the first tension spring 303, so that the first tension spring 303 returns to its initial stretched state, thereby restoring the clamping force to a normal level, and the battery continues to complete the subsequent cutting at a normal speed.

[0028] During the buffering process when the first clamping block 301 slides backward due to excessive cutting resistance, the sliding displacement state triggers the dynamic clamping mechanism 4, thereby applying additional force to the clamping claws on both sides of the battery. This causes the clamping force on the battery to increase synchronously with the increase in cutting resistance. When the buffering ends and the first clamping block 301 resets, the increased clamping force is automatically released and returns to the normal level. This achieves instantaneous reinforcement and fixation of the battery during difficult cutting stages, ensuring that the battery will not shift or shake under high resistance, thereby improving reliability and stability.

[0029] Example 2, please refer to Figures 1-6 Based on Embodiment 1, in this embodiment, two mounting slots 5 are opened through the top of the cutting machine body 1. The inner walls of the two mounting slots 5 are provided with an expansion inner support mechanism 6. The expansion inner support mechanism 6 includes a fixed rod 601, and a slider 602 is slidably connected to the outer wall of the fixed rod 601. A second spring 603 is fixedly connected to the side wall of the slider 602, and the end of the second spring 603 away from the slider 602 is fixedly connected to the inner wall of the mounting slot 5.

[0030] Furthermore, two positioning rods 604 are fixedly connected to the top of the slider 602. Each positioning rod 604 has a movable plate 605 on its outer wall. A positioning groove 606 is opened through the interior of the movable plate 605. The inner wall of the positioning groove 606 is slidably connected to the outer wall of the positioning rod 604. A third spring 607 is fixedly connected to the outer wall of the positioning rod 604. The end of the third spring 607 away from the positioning rod 604 is fixedly connected to the inner wall of the movable plate 605. A connecting block 609 is fixedly connected to one end of each movable plate 605. A flip plate 608 is fixedly connected to the end of the movable plate 605 away from the connecting block 609. A second tension spring 610 is fixedly connected between the two connecting blocks 609.

[0031] Specifically, when the moving seat 2 moves the square lithium battery toward the circular saw 9, the circular saw 9 rotates at high speed under the drive of the motor drive assembly 8. When it contacts the battery casing and begins to cut and form an initial cut, the expansion inner support mechanism 6 is installed in the mounting groove 5 on the cutting machine body 1. Its position is precisely adjusted so that the sides of the two flipping plates 608 are facing the rear of the cutting path of the circular saw 9. After the circular saw 9 cuts a cut to a certain depth, as the battery continues to be fed, the cut moves to contact the expansion inner support mechanism 6. At this time, the two flipping plates 608 are in a merged state in the initial state, and their wedge-shaped tips are smoothly inserted into the cut of the battery casing.

[0032] As the battery is further fed in, the cut exerts a relative force on the flip plate 608. This force is then transmitted through the flip plate 608 to the connecting block 609 and the movable plate 605, allowing the slider 602 to slide on the fixed rod 601. At this time, the movable plate 605 can slide along the positioning rod 604. Since the flip plate 608 is inserted into the cut, due to the constraint of the cut, the rear ends of the pair of flip plates 608 are subjected to outward tension, causing the two movable plates 605 to slide along the outer wall of the positioning rod 604. During this process, the third spring 607 is compressed. Because the two movable plates 605 are designed to be inclined, during the sliding process, the end of the plate that is close to the second tension spring 610 will gradually move away. At this time, the flip plate 608 will flip along with the movable plate 605, and the second tension spring 610 will be stretched to buffer and reset.

[0033] While the circular saw 9 cuts a gap in the outer casing, two combined flip plates 608 are inserted into the cut. They are then compressed by the movable plate 605, causing the movable plate 605 to slide along the positioning rod 604 and drive the flip plates 608 to flip outward using a lever principle. During the process, the front ends of the two flip plates 608 remain in contact, while the rear ends gradually open, thereby creating a continuous stretching force on the side walls inside the cut, increasing the gap in the cut, and thus physically isolating the side of the circular saw 9 from the inner wall of the cut in the battery casing, eliminating frictional heat and side wear from the source.

[0034] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0035] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
