The utility model provides a battery disassembly and recovery device which is used for decomposing a single battery assembly, wherein the battery assembly comprises a battery shell and a plurality of battery cores arranged in the battery shell. The battery cases of the battery modules currently on the market are generally square, and therefore, the following embodiments of the present utility model are described by taking the example of disassembling square batteries, but are not limited thereto.

In the embodiment of the present utility model, as shown in fig. 1 to 14, the battery separation and recovery device includes a base 10, a cutting mechanism 20, and a case core separating mechanism 30.

The base 10 is configured as a base carrier of the battery disassembling and recycling device, the base 10 has a feeding end and a discharging end which are opposite to each other, and the battery to be recycled can be conveyed from the feeding end of the base 10 to the discharging end of the base 10 by a conveying mechanism (not shown).

Further, a cutting mechanism 20 is mounted to the base 10, the cutting mechanism 20 being for cutting off battery cases of at least opposite sides of the battery to be recovered. That is, after being cut by the cutting mechanism 20, the battery cases on the opposite sides of the battery to be recovered are cut off. The purpose of this arrangement is to expose the battery cells in the battery case so that the battery cells can be pushed out of the battery case by the case-cell separation mechanism 30 to complete the separation of the battery case from the battery cells.

Specifically, in the present embodiment, the base 10 has three cutting stations that are sequentially spaced between the feed end and the discharge end of the base 10. The cutting mechanism 20 includes a cutter 21, and each cutting station is provided with a cutter 21 in a liftable manner, and the cutter 21 can be lifted up or down compared with the base 10 to cut the battery cases of different sides of the battery to be recovered. In this embodiment, the purpose of providing three cutting stations is to be able to cut off the battery cases of the adjacent three sides of the battery to be recovered simultaneously, so as to facilitate pushing out the battery cells. The mode of cutting off the battery shell of the battery to be recovered by the cutter 21 has the advantages of high efficiency and no waste scraps pollution.

It should be noted that, the design of the present application is not limited thereto, and in other embodiments, only two cutting stations may be provided on the base 10, and only the battery cases on opposite sides of the battery to be recovered may be cut off. In some embodiments, only one cutting operation may be provided on the base 10, and the cutting mechanism 20 may complete the cutting of the side battery case of the battery to be recovered at the one cutting station.

It should be further noted that, in some embodiments, the cutter 21 may be configured to move horizontally on the base 10, or be rotatably connected to the base 10.

Further, the shell-core separation mechanism 30 is disposed at the discharge end of the base 10, and the shell-core separation mechanism 30 is used for separating the shell from the core of the cut battery to be recovered, so as to realize separate recovery processing of the battery shell and the battery core.

Specifically, the core-shell separating mechanism 30 includes a supporting plate 31, a pressing plate 32 and a pushing-out member 33, wherein the supporting plate 31 is mounted on the base 10, and the supporting plate 31 is used for supporting the cut battery to be recovered.

The pressing plate 32 is disposed opposite to the supporting plate 31, and a battery clamping space is formed between the pressing plate 32 and the supporting plate 31. Wherein the battery clamping space is used for fixing the battery so that the pushing-out member 33 pushes out the battery cell. Further, a pressing plate 32 is movably provided on the base 10 and is movable in a direction approaching and moving away from the pallet 31, and the pressing plate 32 is used for clamping the cut battery in cooperation with the pallet 31. Specifically, when the cut battery to be recovered is conveyed onto the pallet 31, the pressing plate 32 can be moved in the direction of the pallet 31 to clamp the battery to be recovered in cooperation with the bearing plate 31. When the battery cells are pushed out, the pressing plate 32 can move away from the supporting plate 31 to release the battery case.

The pushing member 33 is movably disposed on the base 10, and the pushing member 33 can move from one side of the supporting plate 31 to the other side of the supporting plate 31 through the battery clamping space, so as to push out the battery core of the battery. Specifically, the ejector 33 may move from one side of the pallet 31 to the other side of the pallet 31, and since the ejector 33 passes through the battery clamping space during the movement, when the cut battery is clamped in the battery clamping space by the pallet 31 and the pressing plate 32, the ejector 33 may push out the battery core of the battery to be recovered, thereby completing the separation of the battery case and the battery core. The design is that the battery shell is not required to be completely cut, the separation of the battery core and the battery shell can be completed, the steps required by the separation of the battery core and the battery shell are fewer, the shell core separation efficiency is improved, the manual participation can be reduced, and the labor cost is reduced.

It can be appreciated that, in the battery disassembling device according to the technical scheme of the application, the cutting mechanism 20 is arranged on the base 10 to cut the battery shells on at least two opposite sides of the battery to be recovered, the pressing plate 32 and the supporting plate 31 are matched to clamp and cut the finished battery shells, and finally the battery core is pushed out of the battery shells through the push-out piece 33 to complete the separation of the battery shells and the battery core, so that the battery shell core separation efficiency can be improved, and the labor cost can be reduced. In addition, the partial battery shell is cut off in a cutting mode, so that the cutting efficiency is high, and no scraps are generated. Therefore, compared with the traditional scheme of completely cutting off the battery shell to separate the battery shell and the battery core, the battery disassembly and recovery device of the technical scheme has the advantages of high recovery efficiency and low manpower cost.

In some embodiments, the pressing plate 32 is slidably provided at an upper side of the pallet 31, and is slidable in an up-down direction to approach and separate from the pallet 31. Here, the vertical direction is a direction obtained by referencing the base 10, and since the battery disassembling device is usually directly mounted on the ground, the vertical direction referred to herein may be referenced to the ground.

Further, in the present embodiment, the shell-core separation mechanism 30 further includes a cylinder (not shown) for driving the pressing plate 32 to slide up and down. The cylinder is used as a driving mechanism to drive the pressing plate 32 to slide, and the driving mechanism has the advantages of simple driving mode, stable movement of the pressing plate 32 and the like. It should be noted that the driving mechanism of the platen 32 is not limited to an air cylinder, and in some embodiments, a hydraulic cylinder, a motor, or the like may be selected as the driving mechanism to drive the platen 32 to move. In this case, when the motor is selected as the driving mechanism of the platen 32, a corresponding transmission structure, such as a rack-and-pinion structure, a chain transmission mechanism, a screw slider structure, etc., may be provided between the motor and the platen 32 in order to improve the stability and transmission efficiency of the power transmission between the motor and the platen 32.

It can be appreciated that limiting the movement of the platen 32 to sliding helps to simplify the movement track of the platen 32, thereby helping to reduce the structural complexity of the core-shell separation mechanism 30 and improve the working stability of the core-shell separation mechanism 30. Of course, the design of the present application is not limited thereto, and in other embodiments, the platen 32 may be configured to be rotatably coupled to the base 10, in which case the platen 32 may be rotated about an axis of rotation to move closer to and farther from the pallet 31.

On the basis of the above-described embodiment, the push-out member 33 slides in a direction substantially parallel to the horizontal plane to enter and leave the battery clamping space. Here, the ground or the bearing surface of the base 10 may be regarded as a horizontal plane, and sliding of the ejector 33 in a direction substantially parallel to the horizontal plane means that the angle between the sliding direction of the ejector 33 and the horizontal plane is not more than 30 °. Specifically, the core-separating mechanism 30 further includes a cylinder (not shown) that drives the ejector 33 to slide in a direction substantially parallel to the horizontal plane. The cylinder is used as a driving mechanism to drive the ejector 33 to slide, and the advantages of simple driving mode, stable movement of the ejector 33 and the like are achieved. It should be noted that the driving mechanism of the ejector 33 is not limited to an air cylinder, and in some embodiments, a hydraulic cylinder, a motor, or the like may be selected as the driving mechanism to drive the ejector 33 to move. In this case, when a motor is selected as the driving mechanism of the ejector 33, a corresponding transmission mechanism, such as a rack-and-pinion mechanism, a chain transmission mechanism, a screw slider mechanism, etc., may be provided between the motor and the ejector 33 in order to improve the stability and transmission efficiency of the power transmission between the motor and the ejector 33.

It will be appreciated that restricting the pushing member 33 to slide in a direction substantially parallel to the horizontal plane enables the pushing member 33 to push out the battery with a simple movement locus, thereby contributing to a reduction in the structural complexity of the core-in-housing separation mechanism 30 and an improvement in the operational stability of the core-in-housing separation mechanism 30. Of course, the design of the present application is not limited thereto, and in other embodiments, the ejector 33 may be provided rotatably connected to the base 10, and the pressing plate 32 may be rotated about a rotation axis to enter and leave the battery clamping space.

Specifically, when three cutting blades 21 are movably provided on the base 10, the three-sided battery case of the cut battery to be recovered is cut off. If the three cut sides of the battery to be recovered are left, right and front sides, respectively, then the pushing member 33 may pass through the front side of the battery to be recovered and extend in the front-rear direction of the battery to be recovered to push out the battery cells. This design is advantageous in reducing the structural complexity of the core-shell separation mechanism 30. Of course, the design of the present application is not limited thereto, and in other embodiments, the push-out member 33 may extend in the left-right direction of the battery to be recovered.

In some embodiments, the pushing member 33 includes a sliding rod 331 and a pushing structure 332, one end of the sliding rod 331 is slidably connected to the base 10, the other end extends toward the battery clamping space, the pushing structure 332 is protruding from the other end of the sliding rod 331, and the pushing structure 332 can enter or leave the battery clamping space along with the sliding of the sliding rod 331. Specifically, one end of the slide bar 331 is slidably connected to the base 10 via a slide rail structure (not shown), and is drivingly connected to the cylinder. The pushing structure 332 is used for pushing out the battery core, and since the pushing structure 332 is protruding on the sliding rod 331, the contact area between the pushing member 33 and the battery core can be increased on the basis of controlling the size of the sliding rod 331. In this way, not only can the effective ejection of the battery cells be ensured, but also the weight of the ejector 33 can be reduced, and the power requirement on the driving structure of the ejector 33 can be reduced.

In some embodiments, the push structure 332 includes a connecting plate 332a and a tilt plate 332b, the connecting plate 332a being connected to the slide bar 331, the tilt plate 332b being connected to the connecting plate 332a and extending obliquely upward from the slide bar 331. Specifically, the ejector 33 has a first position on one side of the pallet 31 and a second position on the other side of the pallet 31, and the ejector 33 is capable of ejecting the battery cell when the ejector 33 moves from the first position to the second position. When the ejector 33 is in the first position, the inclined plate 332b extends obliquely in a direction away from the battery clamping space.

It can be appreciated that, by the arrangement of the inclined plate 332b, the structural stability of the pushing structure 332 can be enhanced on the basis of ensuring the effective pushing out of the battery core, so as to improve the working stability of the pushing-out member. Of course, the design of the present application is not limited thereto, and in other embodiments, the inclined plate 332b may be disposed to extend vertically upward or to extend obliquely toward the direction of the battery clamping space.

Alternatively, the connecting plate 332a and the inclined plate 332b are integrally formed, so as to improve the structural strength of the pushing structure 332 and reduce the production cost of the pushing structure 332.

Specifically, one side of the pallet 31 in the moving direction of the ejector 33 is the battery cell falling side. Specifically, after the battery cells are pushed out by the push-out member 33, the push-out member 33 continues to move until the battery cells are pushed off from the battery cell falling side of the pallet 31.

In some embodiments, the battery disassembly and recycling device of the present application further includes a battery cell recycling assembly 40, where the battery cell recycling assembly 40 is disposed on the falling side of the battery cell to recycle the battery cell pushed out by the push-out member 33. By this battery cell recovery unit 40, the battery cells can be recovered independently by recovering the pushed battery cells.

Specifically, the battery core recycling assembly 40 includes a first collecting tank 41 and a first filtering tank 42, wherein the first collecting tank 41 is formed with a first liquid collecting chamber 41a, a first feed port 411 communicating with the first liquid collecting chamber 41a is provided at the top of the first collecting tank 41, and a first connection port 412 communicating with the first liquid collecting chamber 41a is provided at the side of the first collecting tank 41; the first filter box 42 is movably connected with the first collecting box 41, the first filter box 42 can enter or leave the first liquid collecting cavity 41a from the first connecting port 412, the first filter box 42 is arranged towards the first feeding port 411 in an open mode, the first filter box 42 comprises a first bottom plate 421, the first bottom plate 421 is arranged at intervals with the bottom wall of the first liquid collecting cavity 41a, and a first filter structure 421a is arranged on the first bottom plate 421.

Specifically, the battery cells falling from the battery cell falling side of the tray 31 enter the first collecting box 41 from the first feed port 411 and fall into the first filter box 42, and the electrolyte on the battery cells can enter the first collecting box 41 from the bottom plate of the first filter box 42 due to the first filter structure 421a, and the battery cells can be collected in the first filter box 42. When a sufficient number of battery cells are collected in the first filter box 42, the first connection port 412 in the first filter box 42 may be removed to separately recover the battery cells, while the battery liquid remains in the first collection box 41 to be separately recovered. It should be noted that, when the battery cells in the first filter box 42 are all taken out, the first filter box 42 may be replaced in the first collecting box 41 to continue the collection of the battery cells.

It can be appreciated that through the design of the first filter box 42, the separation of the battery core and the electrolyte and the independent recovery of the battery core and the electrolyte can be realized, so that the treatment of the battery core and the electrolyte by the subsequent treatment process is facilitated, and the disassembly recovery efficiency and recovery rate of the battery are improved.

In some embodiments, the first filter structures 421a on the first bottom plate 421 are provided as strip-shaped holes. It can be appreciated that the strip-shaped holes are provided as a filtering structure, which is beneficial to improving the hollowed-out area on the first bottom plate 421 so as to more fully separate the battery core from the electrolyte. Of course, the design of the present application is not limited thereto, and in other embodiments, the first filter structure 421a may be configured as a circular hole, a hexagonal hole, a square hole, or the like.

In some embodiments, the first filter box 42 is slidingly connected to the first collection box 41. The first filter tank 42 is provided in sliding connection with the first collecting tank 41, so that the movement locus of the first filter tank 42 and the connection structure of the first filter tank 42 and the first collecting tank 41 can be simplified, so that the first filter tank 42 enters and leaves the first collecting tank 41. Of course, the design of the present application is not limited thereto, and in other embodiments, the first filter box 42 may be provided as the first collecting box 41 rotatably connected.

In some embodiments, the first filter box 42 further includes a first side plate 422, the first side plate 422 is enclosed on a peripheral side of the first bottom plate 421, one end of the first bottom plate 421 is a rotating end, the other end is a free end, the rotating end is rotatably connected to the first side plate 422, and a lower surface of the first bottom plate 421 abuts against a side wall of the first connection port 412. That is, the first bottom plate 421 is rotatable, and since the lower surface of the first bottom plate 421 abuts against the sidewall of the first connection port 412, the first bottom plate 421 can rotate under the action of gravity as the first filter box 42 moves.

Specifically, the first filter box 42 has a first position into the first collection box 41 and a second position at least partially out of the first collection box 41,

when the first filter box 42 is in the first position, the first bottom plate 421 is kept substantially horizontal and encloses with the first side plate 422 to form a containing cavity of the first filter box 42;

when the first filter box 42 is in the second position, the first bottom plate 421 is inclined downward, and the free end of the first bottom plate 421 is spaced apart from the first side plate 422 to form a drop gap.
