[0002] The refined disassembly of battery cells is a key technology for achieving efficient recycling and resource reuse of waste batteries. Its core goal is to safely and environmentally friendly extract valuable materials from batteries, such as positive and negative electrode materials, electrolytes and diaphragms. During the disassembly process, it is necessary to undergo pretreatment first to ensure the safety and operability of the disassembly, and then cut the outer shell by mechanical cutting to separate the outer shell from the movement, and efficiently separate the positive and negative electrode sheets from the diaphragm in the core package. The separated electrode sheets are then separated from the active substances and current collectors for further recycling and purification. Before processing the core package, the core package needs to be separated from the battery so as to achieve the purpose of recycling the core package and the outer shell at the same time.

[0016] The beneficial effects of the present invention are: During the process of cutting the battery, it needs to be moved between different workstations. However, due to the different sizes of batteries of different specifications and manufacturers, the transportation structure needs to be able to be adjusted according to the size of the battery during the movement of the battery. Therefore, the clamping parts provided in the present invention can adjust the size of the opening thereof when the mobile frame moves along the guide frame to the upper end of the battery, so as to adapt to the sizes of different batteries. Therefore, the battery can be in a relatively stable state during the transportation process and is not easy to fall off.

[0017] When cutting batteries, it is generally necessary to go from the inspection station to the cutting station and then to the second cutting station. If it is continuously circulated through only one clamp, its turnover efficiency is very low. Therefore, the present invention sets a first toggle member and a second toggle member at the lower end of the movable frame on the basis of the clamp. In the process of the movable frame driving the clamp to move, the first toggle member and the second toggle member will also be moved accordingly, and at the same time drive the battery on its side to move forward. Therefore, only one set of power is needed to drive the batteries on three stations to move at the same time, which greatly reduces the components of the transfer device, so that the overall structure can be more compact and occupy a smaller area.

[0018] In the positioning structure of the existing battery cutting device, the positioning structure is usually arranged around the cutting structure, which easily causes the phenomenon that the rear end of the battery warps or swings during the cutting process. Therefore, the present invention first fixes the front end at the front of the battery cutting point through the first positioning structure, and a second positioning structure is also arranged in the opposite direction of the first positioning structure, so as to be able to fix the rear end of the battery, and thus can realize the fixation at two points, the front and the rear, of the battery, and further achieve a stable positioning effect during the cutting process of the first cutting member. At the same time, the adjustment of the lateral positioning adjustment member can also enable the second positioning structure to adapt to the size of the battery. Even when cutting a small battery, the second positioning structure can be moved to the corresponding position through the lateral positioning adjustment member, with strong adaptability and the ability to accurately position the battery at multiple points.

[0019] In the prior art, when the core package is pushed out, the packaging film of the core package is also pushed out at the same time, so that the packaging film still covers the outside of the core package, and separate processing steps are required. Therefore, the present invention cooperates the front-end positioning component of the core package with the rear-end positioning component of the core package. During the process of pressing both ends of the battery shell, the film clamping member is hooked on the inner side wall of the battery shell at the same time, so that the packaging film can be left in the shell when the core package is pushed out, which is convenient for subsequent processing.

[0020] When dealing with batteries of different specifications, after detecting the specifications of the batteries in advance, by changing the size of the pushing component, it is possible to adapt to batteries of different specifications, and further adapt to the size of the core package when pushing out the core package, and push out the core package completely without damaging the core package.

[0021] In summary, the present invention moves the battery by arranging a guiding frame and a moving frame on the transfer machine table, and separately arranges a first positioning structure and a second positioning structure on both sides of the guiding frame to position and cut the battery shell. The cut battery is directly transported to the tiltable table surface at the end of the guiding frame, and the core package is pushed out by the adjustable pushing component, so that multiple modules can be integrated on one transfer machine table. While the structures are compact, the batch processing efficiency of the battery is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0040] Reference Figures 1 to 14 As shown, a separation mechanism for a battery shell and a core package comprises a transfer machine 20; a guide frame 21 is provided on the transfer machine 20, and a reciprocating movable frame 22 is slidably mounted on the guide frame 21; an adaptive clamping structure 23 comprises a clamping piece 231 with an adjustable clamping spacing arranged at the lower end of the movable frame 22, the clamping piece 231 is close to the side of the battery feed, and the clamping piece 231 is provided with a toggle assembly on the side away from the battery feed, and when the clamping piece 231 drives the battery to move, the toggle assembly simultaneously drives the battery to move forward; a first positioning structure 31 fixed on the transfer machine 20 and located on the side of the guide frame 21, the first positioning structure 31 comprises a first positioning piece 311 for positioning the battery, and a first cutting piece 312 is movably mounted on the side of the first positioning piece 311 away from the battery; a second positioning structure 32 arranged opposite to the first positioning structure 31 and located on the other side of the guide frame 21, the second positioning structure 32 comprises A transverse positioning adjustment member 321 is arranged on the transfer machine 20, and a second positioning member 322 is slidably installed in the transverse positioning adjustment member 321. When the first positioning member 311 cooperates with the battery, the transverse positioning adjustment member 321 drives the second positioning member 322 to move and the second positioning member 322 is pressed against the battery; a core package front end positioning component 41 is located in the middle of the transfer machine 20 and connected to the guide frame 21; a core package rear end positioning component 42 is arranged opposite to the core package front end positioning component 41, and the core package rear end positioning component 42 pushes the core package against the core package front end positioning component 41 after being pushed out, and a film clamping member 424 is arranged on the core package rear end positioning component 42, and the film clamping member 424 hooks the inner side of the battery shell after the core package rear end positioning component 42 is pushed out; an adjustable pushing component 43 is arranged on the side of the core package, including a core package power component 431 for pushing and pushing, and a height-adjustable pushing component 432 is arranged on the output end of the core package power component 431.

[0041] During the process of cutting the battery, it needs to be moved between different workstations. However, due to the different sizes of batteries of different specifications and manufacturers, the transportation structure needs to be able to be adjusted according to the size of the battery during the movement of the battery. Therefore, the clamping part 231 provided in this embodiment can adjust its own opening size when the mobile frame 22 moves to the upper end of the battery along the guide frame 21, so as to adapt to the size of different batteries. Therefore, the battery can be in a relatively stable state during the transportation process and is not easy to fall.

[0042] When cutting batteries, it is generally necessary to go from the inspection station to the cutting station and then to the second cutting station. If only one clamping member 231 is used to continuously circulate, its turnover efficiency is very low. Therefore, in this embodiment, a first toggle member 232 and a second toggle member 233 are set at the lower end of the movable frame 22 on the basis of the clamping member 231. In the process of the movable frame 22 driving the clamping member 231 to move, the first toggle member 232 and the second toggle member 233 will also be moved accordingly, and at the same time drive the batteries on its side to move forward. Therefore, only one set of power is needed to drive the batteries on three stations to move at the same time, which greatly reduces the components of the transfer device, so that the overall structure can be more compact and occupy a smaller area.

[0043] During the transportation of the battery, it first needs to move from the voltage detection station to the rest station, and this part is achieved by the movement of the mobile frame 22 on the guide frame 21. Therefore, the guide frame 21 needs to guide the movement direction of the limited mobile frame 22. The guide frame 21 includes a lifting frame 211 for increasing the height. A transverse guide plate 212 is installed on the lifting frame 211. At least two transverse guide rails 213 are locked on the inner side of the transverse guide plate 212. One end of the transverse guide plate 212 is connected to an axial output member 214. The mobile frame 22 is slidably installed on the transverse guide rail 213, so that the mobile frame 22 can move laterally along the transverse guide rail 213.

[0044] The power of the moving frame 22 is installed on the transverse guide plate 212. In the present embodiment, the axial output member 214 includes a transverse drive motor 2141 locked on one side of the transverse guide plate 212. The transverse drive motor 2141 is connected to a transverse moving screw rod 2142. The transverse moving screw rod 2142 cooperates with the moving frame 22 through a slider, thereby realizing the transverse movement of the moving frame 22 by cooperating with the transverse moving screw rod 2142 and the slider. In other embodiments, other driving methods may also be used.

[0045] In the setting process of the traditional moving frame 22, most of the time, only a liftable motor is set on the transverse moving structure to complete the overall deployment. However, in this embodiment, the moving frame 22 includes a transverse moving plate 221 that cooperates with the transverse guide rail 213, and the transverse moving plate 221 is provided with a lower moving push rod 222 and a longitudinal guide block 223. The output end of the lower moving push rod 222 is connected to a longitudinal moving plate 224, and the longitudinal moving plate 224 is slidably connected to the longitudinal guide block 223. An extension plate 225 is set at the bottom of the longitudinal guide block 223, and the clamping part 231 and the toggle assembly are arranged below the extension plate 225, so that the effects of transverse movement, longitudinal movement, and transverse multi-workpiece adjustment can be achieved simultaneously.

[0046] The clamping member 231 is the first step of clamping. Specifically, the clamping member 231 includes a fixed clamping plate 2311 arranged on one side of the bottom surface of the extension plate 225, and a movable clamping plate 2312 slidably connected to the extension plate 225 is arranged on the opposite side of the fixed clamping plate 2311. The movable clamping plate 2312 is driven by a transverse cylinder 2313. The distance between the fixed clamping plate 2311 and the movable clamping plate 2312 is adjustable so that the transfer device can adapt to batteries of most specifications, thereby improving the adaptability of the device.

[0047] In the present embodiment, since there are multiple workstations, in order to adapt to the multiple workstations, the toggle assembly includes a first toggle member 232 and a second toggle member 233. The first toggle member 232 and the second toggle member 233 have the same structure and are arranged in opposite directions. The first toggle member 232 includes a middle locking frame 2321 fixed at the middle position of the bottom of the extension plate 225, and a toggle cylinder 2322 is locked below the middle locking frame 2321. A toggle plate 2323 is arranged on the output end of the toggle cylinder 2322. In fact, different numbers of toggle members can be added according to the number of workstations. The longest and shortest toggle plates 2323 can adapt to batteries of the largest and smallest specifications.

[0048] There is a certain distance between the two toggle members. If the battery in between cannot be guided and limited separately, it is easy to shift. Therefore, a lower extension guide rail 2251 is provided at the bottom of the extension plate 225 of this embodiment. A middle clamping member 234 located between the first toggle member 232 and the second toggle member 233 is slidably installed on the lower extension guide rail 2251. The middle clamping member 234 is connected to the toggle cylinder 2322 through an extension rod 235. When the toggle cylinder 2322 is pushed out, the distance between the middle clamping member 234 and the first toggle member 232 becomes longer. The separately arranged middle clamping member 234 can realize the adaptive change of its own position without the need for a separately arranged power member, thereby improving the invention of this case without increasing components and circuits.

[0049] In this embodiment, the middle clamping member 234 includes a middle moving seat 2341 slidably connected to the lower extending guide rail 2251, and one side of the middle moving seat 2341 is locked with an auxiliary shifting cylinder 2342. The output end of the auxiliary shifting cylinder 2342 is connected to an auxiliary plate 2343. When encountering a battery with smaller specifications, the auxiliary plate 2343 can be extended to the longest, thereby ensuring that the small battery can also be clamped by the middle clamping member 234.

[0050] In the positioning structure of the existing battery cutting device, the positioning structure is usually arranged around the cutting structure, which may easily cause the rear end of the battery to warp or swing during the cutting process. Therefore, the present invention first uses the first positioning structure 31 to position and fix the front end of the battery cutting point, and also sets a second positioning structure 32 in the opposite direction of the first positioning structure 31, so that the rear end of the battery can also be positioned and fixed, thereby achieving fixation at two points in front and behind the battery, and then achieving a stable positioning effect during the cutting process of the first cutting piece 312. At the same time, the adjustment of the lateral positioning adjustment piece 321 can also enable the second positioning structure 32 to adapt to the size of the battery. Even when cutting a small battery, the second positioning structure 32 can be moved to the corresponding position through the lateral positioning adjustment piece 321. It has strong adaptability and can accurately and multi-point position the battery.

[0051] In this embodiment, the first positioning structure 31 and the second positioning structure 32 are used to cut off one side of the battery casing, and usually the battery casing needs to be cut off on both sides, so it is necessary to set up a second group of first positioning structures 31 and second positioning structures 32, and the second group of first positioning structures 31 and second positioning structures 32 are centrally symmetrical with the first group of first positioning structures 31 and second positioning structures 32.

[0052] After the battery is transferred, due to the different specifications of the battery, it may not be able to accurately reach the position of the cutting structure. Therefore, a rib groove is provided on the transfer machine 20 of the present invention, and an initial positioning member 33 slidably connected to the rib groove is provided on the side of the second positioning structure 32 close to the battery. When the battery moves to the front end of the first positioning structure 31, the initial positioning member 33 pushes the battery into the first positioning structure 31, wherein the initial positioning member 33 is an embedded push rod structure, so that the battery can be pushed to the position of the first cutting member 312 and the first positioning member 311 through the initial positioning member 33 to form an initial positioning.

[0053] After the battery is pushed to the initial position, it is first positioned by the first positioning member 311. Specifically, the first positioning member 311 includes a positioning gantry 3111 provided on the table surface of the transfer machine 20. A first pressing plate driving member 3112 and a first cutting push rod 3113 are respectively provided on the positioning gantry 3111. A housing pressing frame 3114 is connected to the lower end of the first pressing plate driving member 3112, and a cutting knife 3115 is connected to the output end of the first cutting push rod 3113. The housing pressing frame 3114 and the cutting knife 3115 can be respectively driven to act by the first pressing plate driving member 3112 and the first cutting push rod 3113, so that the housing pressing frame 3114 first presses down and then the cutting knife 3115 moves downward.

[0054] Specifically, the housing pressing frame 3114 includes a pressing frame slider 31141 connected to the first pressing plate driving member 3112. The pressing frame slider 31141 is locked on a pressing plate 31142. A reinforcing plate 31143 is locked above the pressing plate 31142. The reinforcing plate 31143 is slidably matched with a positioning frame guide rail 31111 inside the positioning gantry 3111 through a pressing plate slider 31144. When positioning the front end of the battery, the first pressing plate driving member 3112 drives the reinforcing plate 31143 to press down along the positioning frame guide rail 31111, so that the pressing plate 31142 presses the battery.

[0055] The cut battery housing needs to be processed. If it is directly left on the transfer machine 20, it will cause accumulation. Therefore, a housing receiving groove 34 is provided at the lower end of the positioning gantry 3111 in this embodiment. An auxiliary housing positioning member 35 is provided on the side of the housing receiving groove 34 away from the battery. When the auxiliary housing positioning member 35 is pushed out, the initial positioning member 33 pushes the battery to fit with the auxiliary housing positioning member 35. The initial positioning member 33 and the auxiliary housing positioning member 35 can form an opposing fit. Combining the first positioning structure 31 and the second positioning structure 32, the battery will be positioned at four points before cutting. After the battery housing is cut, not only the cut housing part will fall into the housing receiving groove 34, but also part of the electrolyte in the housing will flow into the housing receiving groove 34 along the cut. And due to the pressure generated by the second positioning structure 32 at the rear end, the electrolyte at the rear end will also be pressed forward, flowing out along the direction of the cut, so as to discharge the electrolyte in the battery as much as possible and reduce the difficulty of subsequent processing.

[0056] The position of the second positioning member 322 is not fixed and needs to be changed according to the size of the battery. Specifically, a second positioning frame movable guide rail 3211 is provided on the lateral positioning adjustment member 321, and the second positioning member 322 includes a second positioning slider 3221 that movably cooperates with the second positioning frame movable guide rail 3211, and the second positioning slider 3221 is locked on a second positioning plate 3222, and the second positioning plate 3222 is connected to the lateral positioning screw of the lateral positioning adjustment member 321 through a nut, so that the second positioning plate 3222 can adjust the distance between it and the first positioning structure 31 according to the size of the battery.

[0057] The second positioning plate 3222 itself can achieve movement on the Z axis. Specifically, the second positioning plate 322 also includes a second positioning guide rail 3223 locked on the second positioning plate 3222. The top of the second positioning plate 3222 is locked with a second positioning push rod 3224. The bottom of the second positioning push rod 3224 is connected to an opposite side clamping frame 3225 that is slidably fitted on the second positioning guide rail 3223. The opposite side clamping frame 3225 is pressed against the rear end of the top surface of the battery, thereby preventing the rear end of the battery from tilting, laying a good foundation for the next stage of cutting or positioning.

[0058] In order to avoid flattening the battery during the battery positioning process, the opposite side clamping frame 3225 includes an opposite side matching plate 32251 that cooperates with the second positioning guide rail 3223, and a reversing block 32252 is locked on the opposite side matching plate 32251, and an opposite side clamping plate 32253 is locked on the reversing block 32252. The opposite side clamping plate 32253 is pressed on the rear end of the battery, so that the opposite side clamping plate 32253 and the second positioning push rod 3224 are staggered and not in the same straight line, thereby realizing staggered pressure.

[0059] The prior art will push out the membrane of the core package together with the core package when pushing out the core package, so that the membrane is still covered on the outside of the core package, and a separate processing step is required. Therefore, the present invention cooperates with the core package front end positioning component 41 and the core package rear end positioning component 42. When the battery shell is pressed at both ends, the membrane clamping member 424 is hooked on the inner wall of the battery shell at the same time, so that the membrane can be retained in the shell when the core package is pushed out, which is convenient for subsequent processing.

[0060] When dealing with batteries of different specifications, after detecting the specifications of the batteries in advance, the size of the ejection component 432 can be changed to adapt to batteries of different specifications, so that the size of the core package can be adapted when the core package is ejected, and the core package will not be damaged when it is completely ejected.

[0061] After the battery case is cut, the core package inside it needs to be pushed out. Before the core package is pushed out, it needs to be fixed. Therefore, in this embodiment, the core package front-end positioning assembly 41 includes a core package positioning gantry 411 fixed on the transfer machine table 20. A core package positioning push rod 412 is provided on the core package positioning gantry 411. A front core package positioning member 413 is provided at the bottom end of the core package positioning push rod 412. Before the core package is moved to the pushing station, the core package positioning push rod 412 rises to make way for the battery. After reaching the station, the core package positioning push rod 412 moves down and uses the front core package positioning member 413 as a fixing surface on one side.

[0062] Since batteries come in different sizes, to avoid the situation where a too-small battery cannot be fixed by the front core package positioning member 413, the front core package positioning member 413 in this embodiment includes a core package push rod mounting frame 4131 locked to the core package positioning push rod 412. A core package lateral push rod 4132 is provided at the lower end of the core package push rod mounting frame 4131. A core package front baffle 4133 is connected to the output end of the core package lateral push rod 4132. The position-adjustable core package front baffle 4133 can be used to adapt to small batteries, thus ensuring that the core package can be pushed out.

[0063] In the fixation of the rear end of the core package, the core package rear-end positioning assembly 42 includes a U-shaped guide frame 421 fixed on the transfer machine table 20. A core package pressing push rod 422 is provided inside the opening of the U-shaped guide frame 421. The core package pressing push rod 422 passes through the U-shaped guide frame 421 and a core package rear baffle 423 is connected to its output end. After the core package rear baffle 423 is pushed out, it abuts against the rear end face of the battery case. The surface of the core package rear baffle 423 in contact with the battery is a rough surface, so as to ensure the abutting effect.

[0064] To ensure the retention effect on the wrapping film and without adding redundant moving parts, a gap is provided on the side of the core package rear baffle 423. The film clamping member 424 is a hook, and the hook is locked in the gap. In this embodiment, the hook has a certain elasticity, so there is no need to specially set up a power structure for position conversion.

[0065] To avoid the misactivation of the core package rear-end positioning assembly 42 and the core package front-end positioning assembly 41, infrared sensors 44 are provided on the sides of both the core package rear-end positioning assembly 42 and the core package front-end positioning assembly 41, and they will only be activated when a battery is sensed approaching.

[0066] Due to different battery specifications, the opening positions after cutting are also different. In order to enable the adjustable pushing component 43 to accurately dock with the opening of the battery housing, the adjustable pushing component 43 includes a first adjusting member 433 connected to the transfer machine table 20, and the core package power component 431 is movably installed on the first adjusting member 433, so that the core package power component 431 can be aligned with the core package.

[0067] The first adjusting member 433 is a structure that can drive the core package power component 431 to move back and forth. Specifically, the first adjusting member 433 includes a pushing member mounting frame 4331 connected to the transfer machine table 20. A pushing frame guide rail 4332 is provided inside the pushing member mounting frame 4331. A pushing slider 4333 that cooperates with the pushing frame guide rail 4332 is provided at the bottom of the core package power component 431. The core package power component 431 is connected to the pushing member mounting frame 4331 through a worm and worm gear.

[0068] In order to adapt to battery housings of different heights and widths, the pushing component 432 includes a core package extension rod 4321 connected to the core package power component 431. A plurality of core package pushing blocks 4322 are locked on the core package extension rod 4321 from bottom to top. The sizes of the core package pushing blocks 4322 can be installed by themselves at the initial stage.

[0069] After the core package is pushed out, the housing needs to be separated and removed separately. In this embodiment, between the core package front-end positioning component 41 and the core package rear-end positioning component 42 is an inclined table 45, which can discharge the housing for separate recycling and processing.

[0070] In summary, the present invention moves the battery by setting a guide frame 21 and a moving frame 22 on the transfer machine table 20, and separately arranges a first positioning structure 31 and a second positioning structure 32 on both sides of the guide frame 21 to position and cut the battery housing. The cut battery is directly transported to the inclined table at the end of the guide frame 21, and the core package is pushed out by the adjustable pushing component 43. Thus, multiple modules can be integrated on one transfer machine table 20. While the structures are compact, the batch processing efficiency of the battery is ensured.

[0071] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
