Description

Technical Field

[0001] This invention relates to the field of waste lithium battery dismantling technology, specifically to a waste lithium battery recycling and dismantling equipment. Background Technology

[0002] During the lithium battery research and development phase, for batteries that have undergone performance testing or that exhibit defects such as short circuits or abnormal internal resistance during production, analytical technicians will perform necessary disassembly and analysis. The integrity of the battery core obtained from disassembly directly affects the accuracy of the analytical data and, more importantly, the accuracy of the overall battery quality analysis results.

[0003] For example, Chinese Patent Publication No. CN115740600A discloses a battery dismantling device and a lithium battery dismantling and recycling machine. The aforementioned battery dismantling device includes a dismantling table and dismantling components; the dismantling components include a dismantling indexing plate, a feeding component, an end cap cutting component, a shell flanging component, and a discharging component; the dismantling indexing plate is rotatably mounted on the dismantling table; the feeding component, the end cap cutting component, the shell flanging component, and the discharging component are all mounted on the dismantling table and arranged sequentially around the dismantling indexing plate.

[0004] In the aforementioned cited document, the disassembly indexing plate rotates the battery to be disassembled. The end cap cutting component separates the end cap of the battery to be disassembled from the outer casing, forming a cutting groove on the outer casing to expose the core. Then, the casing flange component squeezes the outer casing, causing it to fold outward, thereby increasing the diameter of the outer casing and allowing it to detach from the core. This makes it easier for the unloading component to remove the core completely from the outer casing, effectively reducing the probability of damage to the core and thus effectively improving the integrity of the core after disassembly.

[0005] However, when dismantling the aforementioned waste lithium batteries, the casing and the cell are usually sealed during assembly and use. When the casing and cell are forcibly separated by a pressure device during dismantling, the casing and cell may stick together. This can damage the casing and cell during dismantling, making it impossible to recycle them later. In addition, this dismantling process is quite cumbersome. Summary of the Invention

[0006] The purpose of this invention is to provide a waste lithium battery recycling and dismantling equipment that enables pre-separation between the casing and the battery cell during the dismantling of waste lithium batteries, thereby ensuring that the battery cell and casing are relatively intact after dismantling, and that the dismantling is quick and convenient.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste lithium battery recycling and dismantling device, including a dismantling platform, and further comprising: A pressure assembly is fixedly installed on one side edge of the top of the disassembly table. The pressure assembly is used to separate the waste lithium battery cells from the casing. A rotating assembly is mounted on top of the dismantling platform, which is used to circulate and feed multiple sets of waste lithium batteries. A tensioning assembly is installed on the top circumference of the circulating rotating assembly, the tensioning assembly being used to tension the casing of the used lithium battery; A synchronous rotating component installed on the bottom circumference of the circulating rotating component; A support assembly installed on top of each set of tensioning components.

[0008] Preferably, the pressure assembly includes a support frame fixedly installed on the top of the disassembly table near the back, a pressure cylinder fixedly installed on the top of the support frame, a pressure plate fixedly installed on the telescopic end of the pressure cylinder, and a mounting base fixedly installed on the bottom of the disassembly table near the back, with an abutment switch installed on the mounting base for controlling the opening and closing of the pressure cylinder circuit.

[0009] Preferably, the circulating rotation assembly includes an electric turntable rotatably mounted in the middle of the disassembly table, a protective plate is fixedly mounted on the bottom of the electric turntable, and cams are fixedly mounted at equal intervals on the outer circumference of the protective plate.

[0010] Preferably, the tensioning assembly includes a fixed platform fixedly installed on the top circumference of the circulating rotating assembly, and linear slide rails are fixedly installed on the top four sides of the fixed platform. A lever is slidably connected inside the linear slide rail, and a positioning rod is fixedly installed at the bottom of the lever.

[0011] Preferably, the synchronous rotation assembly includes a positioning turntable rotatably mounted on the bottom circumference of the electric turntable, guide grooves are evenly spaced on the top circumference of the positioning turntable, and a positioning toothed ring is fixedly mounted on the outer circumference of the positioning turntable.

[0012] Preferably, positioning gears are rotatably connected at equal intervals at the bottom circumferential edge of the electric turntable, and a torsion spring is fixedly installed between the end of the positioning gear shaft and the bottom of the electric turntable. A fixing ring is fixedly installed at the bottom of the disassembly table, and a toothed block is integrally formed on the inner diameter of the fixing ring. The toothed block and the contact switch are located on the same vertical plane.

[0013] Preferably, the bottom end of the positioning rod extends movably through the linear slide rail to the bottom of the electric turntable, and the bottom end of each set of electric turntables slides in the inner wall of the corresponding guide groove, and each set of guide grooves is interconnected with the corresponding linear slide rail at the top.

[0014] Preferably, the support assembly includes a relief plate installed at the center of the top surface of the fixed platform, and a support spring is fixedly installed between the relief plate and the fixed platform.

[0015] Preferably, the outer edge of each set of positioning gears meshes with the outer edge of the positioning gear ring, and an opening slot is provided on the outer circumference of the protective plate, with the outer edge of each set of positioning gears extending to the outer circumference of the corresponding opening slot.

[0016] Preferably, the mounting base is located on multiple sets of cam rotation paths, and the linear slide rail corresponds one-to-one with the number of the dial plate and the positioning rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the gap between the bottom of the waste lithium battery casing and the battery cell is inserted into the corresponding end of the lever plate on the fixed platform. The electric turntable can circulate and transport the waste lithium batteries corresponding to multiple sets of tensioning components to the bottom of the pressure component. The pressure cylinder extension end drives the pressure plate to pressurize the top of the battery cell. At this time, the four sets of lever plates on the fixed platform can block the casing from pressing down. This allows the battery cell in the waste lithium battery to be quickly separated from the casing. The four sets of tensioning components can circulate and transport multiple sets of waste lithium batteries to the pressure component for disassembly, thus making the disassembly efficiency of waste lithium batteries higher. In this invention, when each tensioning assembly is circulated to the pressure assembly via an electric turntable, the positioning gear in the synchronous rotation assembly can mesh with the toothed block on the fixed ring. This allows the low positioning gear to store power in the torsion spring and then drive the corresponding positioning toothed ring. This causes the positioning toothed ring to rotate below the electric turntable by driving the positioning turntable. When the positioning turntable rotates, the four positioning rods are positioned in the guide groove and can slide along the linear slide rail to the edge of the fixed platform. This allows the gaps around the waste lithium battery casing to be expanded outward by the push plate, which facilitates the subsequent pressurization of the pressure plate and makes the separation of the casing and the cell more thorough and convenient. This also avoids the problem of adhesion between the battery casing and the cell, which could lead to damage to the casing and cell under pressure. In this invention, the cams on the bottom protective plate of the electric turntable are matched with the positions of each tensioning component. After each tensioning component is circulated and transported to the area directly below the pressure component, each cam can sequentially abut against the protruding contact switches on the circumferential path. This allows the pressure cylinder to be electrically controlled and opened by the contact switches, enabling the pressing of the battery cells to proceed immediately after the waste lithium battery casing in the tensioning component below is tensioned. This makes the waste lithium battery recycling and dismantling process closely connected, and the dismantling faster and more convenient. Attached Figure Description

Detailed Implementation

[0020] 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. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: This embodiment introduces a waste lithium battery recycling and dismantling equipment, such as... Figures 1-7 As shown, it includes a disassembly table 100, and also includes: A pressure assembly 200 is fixedly installed on one side edge of the top of the disassembly table 100. The pressure assembly 200 is used to separate the waste lithium battery cells from the casing. The circulating rotating assembly 300, which is mounted on the top of the dismantling table 100, is used to circulate and feed multiple sets of waste lithium batteries. The pressure assembly 200 includes a support frame 21 fixedly installed on the top of the disassembly table 100 near the back. A pressure cylinder 20 is fixedly installed on the top of the support frame 21, and a pressure plate 22 is fixedly installed on the telescopic end of the pressure cylinder 20. A mounting base 23 is fixedly installed on the bottom of the disassembly table 100 near the back. An abutment switch 24 is installed on the mounting base 23. The abutment switch 24 is used to control the opening and closing of the circuit of the pressure cylinder 20. The rotating assembly 300 includes an electric turntable 31 rotatably installed in the middle of the disassembly table 100. A protective plate 32 is fixedly installed on the bottom of the electric turntable 31. The outer circle of the protective plate 32 is... Cams 33 are fixedly installed at equal intervals around the perimeter. The corresponding cams 33 on the bottom protective plate 32 of the electric turntable 31 match the positions of each tensioning assembly 400. In this way, after each tensioning assembly 400 is circulated and transported to the area directly below the pressure assembly 200, each cam 33 can sequentially abut against the protruding contact switch 24 on the circumferential path, thereby allowing the pressure cylinder 20 to be electrically controlled and opened by the contact switch 24. This allows the waste lithium battery casing in the tensioning assembly 400 below to be tensioned, and the cell pressing process to be carried out immediately. This makes the waste lithium battery recycling and dismantling process closely connected.

[0022] In this embodiment, by inserting the gap between the bottom of the waste lithium battery casing and the cell into the end of the corresponding lever 43 on the fixed platform 41, the electric turntable 31 can circulate and transport the corresponding waste lithium batteries from multiple sets of tensioning components 400 to the pressure component 200. The pressure cylinder 20 drives the pressure plate 22 to pressurize the top of the cell. At this time, the four levers 43 on the fixed platform 41 can block the casing from pressing down, so that the cell in the waste lithium battery can be quickly separated from the casing. The four sets of tensioning components 400 can circulate and transport multiple sets of waste lithium batteries to the pressure component 200 for disassembly, thus making the disassembly efficiency of waste lithium batteries higher.

[0023] Example 2: Based on Example 1, this example introduces a waste lithium battery recycling and dismantling equipment, such as... Figures 3-7 As shown, it also includes: A tensioning assembly 400 is installed on the top circumference of the circulating rotating assembly 300. The tensioning assembly 400 is used to tension the casing of the waste lithium battery. Synchronous rotation component 500 is installed on the bottom circumference of the circulating rotation component 300; Support assembly 600 installed on top of each tensioning assembly 400.

[0024] The tensioning assembly 400 includes a fixed platform 41 fixedly installed on the top circumference of the circulating rotation assembly 300. Linear slide rails 42 are fixedly installed around the top of the fixed platform 41. A lever 43 is slidably connected inside the linear slide rails 42. A positioning rod 44 is fixedly installed at the bottom of the lever 43. The synchronous rotation assembly 500 includes a positioning turntable 51 rotatably installed on the bottom circumference of the electric turntable 31. Guide grooves 52 are evenly spaced on the top circumference of the positioning turntable 51. A positioning gear ring 53 is fixedly installed on the outer circumference of the positioning turntable 51. Positioning gears 54 are rotatably connected at equal intervals at the bottom edge of the electric turntable 31. A torsion spring 55 is fixedly installed between the end of the shaft of the positioning gear 54 and the bottom of the electric turntable 31. A fixing ring 56 is fixedly installed at the bottom of the disassembly table 100. A toothed block 57 is integrally formed on the inner diameter of the fixing ring 56. 57 and the contact switch 24 are located on the same vertical plane. When each tensioning component 400 is cyclically transported to the pressure component 200 via the electric turntable 31, the positioning gear 54 in the synchronous rotation component 500 can mesh with the toothed block 57 on the fixed ring 56. This allows the low positioning gear 54 to store force on the torsion spring 55 and then drive the corresponding positioning toothed ring 53. This allows the positioning toothed ring 53 to drive the positioning turntable 51 to rotate below the electric turntable 31. When the positioning turntable 51 rotates, the four positioning rods 44 are positioned in the guide groove 52 and can slide along the linear slide rail 42 to the side of the fixed platform 41. This allows the gaps around the waste lithium battery casing to be expanded outward by the push plate 43, which facilitates the subsequent pressurization of the pressure plate 22 and makes the separation of the casing and the cell more complete and convenient. This also avoids the adhesion between the battery casing and the cell.

[0025] The bottom end of the positioning rod 44 extends through the linear slide rail 42 to the bottom of the electric turntable 31, and the bottom end of each set of electric turntables 31 slides in the inner wall of the corresponding guide groove 52. Each set of guide grooves 52 is interconnected with the corresponding linear slide rail 42 at the top. The support assembly 600 includes a relief plate 61 installed in the middle of the top surface of the fixed platform 41. The outer edge of each set of positioning gears 54 meshes with the outer edge of the positioning gear ring 53. The outer circumference of the protective plate 32 is provided with opening slots, and the outer edge of each set of positioning gears 54 extends to the outer circumference of the corresponding opening slot. The mounting base 23 is located at... On the rotation path of the multiple cams 33, the linear slide rails 42 correspond one-to-one with the number of the dial plates 43 and the positioning rods 44. A support spring 62 is fixedly installed between the relief plate 61 and the fixed platform 41. After the battery cell is pressurized by the pressure plate 22, it can be supported by the lower relief plate 61 and the support spring 62. After the positioning gear 54 in the tensioning assembly 400 is separated from the arc-shaped tooth block 57, it can be quickly reset by the stored torsion spring 55. This allows the corresponding four dial plates 43 to release the inner wall of the lithium battery casing from contact and reset, making it easier to remove the lithium battery casing from the chassis dial plate 43.

[0026] In this embodiment, when each tensioning assembly 400 is cyclically transported to the pressure assembly 200 via the electric turntable 31, the positioning gear 54 in the synchronous rotation assembly 500 can mesh with the toothed block 57 on the fixed ring 56. This allows the low positioning gear 54 to store force on the torsion spring 55 and then drive the corresponding positioning toothed ring 53. This allows the positioning toothed ring 53 to drive the positioning turntable 51 to rotate below the electric turntable 31. When the positioning turntable 51 rotates, the four positioning rods 44 are positioned in the guide groove 52 and can slide along the linear slide rail 42 to the side of the fixed platform 41. This allows the gaps around the waste lithium battery casing to be expanded outward by the push plate 43, which facilitates the subsequent pressurization of the pressure plate 22 and makes the separation of the casing and the cell more thorough and convenient. This also avoids the problem of adhesion between the battery casing and the cell, which could lead to damage to the casing and the cell under pressure. In this embodiment, the cam 33 on the bottom protective plate 32 of the electric turntable 31 is matched with the position of each tensioning assembly 400. After each tensioning assembly 400 is circulated and transported to the area directly below the pressure assembly 200, each cam 33 can sequentially abut against the protruding contact switch 24 on the circumferential path. This allows the pressure cylinder 20 to be electrically controlled and opened by the contact switch 24, thereby enabling the waste lithium battery casing in the tensioning assembly 400 below to be tensioned and the cell pressurization process to be performed immediately. This makes the waste lithium battery recycling and dismantling process closely connected and the dismantling faster and more convenient. Working principle: When disassembling the waste lithium battery casing and cell, the bottom of multiple sets of waste lithium battery casings and the gap of the cell are first inserted into the corresponding ends of the levers 43 on multiple sets of tensioning components 400. The electric turntable 31 can circulate and transport the corresponding waste lithium batteries on multiple sets of tensioning components 400 to the pressure component 200. When each tensioning assembly 400 is circulated and transported to the pressure assembly 200 via the electric turntable 31, the positioning gear 54 in the synchronous rotation assembly 500 can mesh with the tooth block 57 on the fixed ring 56. This allows the low positioning gear 54 to store power in the torsion spring 55 and then drive the corresponding positioning tooth ring 53. This allows the positioning tooth ring 53 to drive the positioning turntable 51 to rotate below the electric turntable 31. When the positioning turntable 51 rotates, the four positioning rods 44 are positioned in the guide groove 52 and can slide along the linear slide rail 42 to the side of the fixed platform 41, thereby allowing the gaps around the waste lithium battery casing to be expanded outward by the push plate 43. The corresponding cam 33 on the bottom protective plate 32 of the electric turntable 31 matches the position of each tensioning component 400. In this way, after each tensioning component 400 is circulated and delivered to the pressure component 200, each cam 33 can sequentially abut against the protruding contact switch 24 on the circumferential path, so that the pressure cylinder 20 can be electrically controlled to open by the contact switch 24. The pressure cylinder 20 can drive the pressure plate 22 to pressurize the top of the battery cell through the extension end of the pressure cylinder 20. At this time, the four sets of levers 43 on the fixed platform 41 can block the outer shell from pressing down. Finally, after the waste lithium battery casing and cell carried by the tensioning assembly 400 directly below the pressure assembly 200 pass through, the cell is pressurized by the pressure plate 22 and can be elastically supported by the lower relief plate 61 and the support spring 62. After the positioning gear 54 in the tensioning assembly 400 separates and meshes with the arc-shaped tooth block 57, it can be quickly reset by the stored torsion spring 55, so that the corresponding four sets of levers 43 can release the inner wall of the lithium battery casing from contact and reset, thus making it easy to remove the lithium battery casing from the chassis levers 43.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
