Description

Technical Field

[0001] The invention belongs to the technical field of waste battery recycling, and in particular relates to a single battery recycling line. Background Art

[0002] New energy technologies are widely used in transportation vehicles and handling equipment. As one of the core components of new energy technologies, power battery packs will gradually decay with the increase in the number of charge and discharge times of power battery packs. When the decay is so severe that it cannot meet the demand for power supply, it needs to be recycled. The current recycling method is generally to cut the battery shell, then take out the battery cell for recycling, and collect the electrolyte that flows out during the cutting process. The existing above-mentioned operations involve multiple recycling processes, including cutting both sides of the shell, circumcising the end of the shell close to the pole ear, pulling the part of the battery cell connected to the end of the shell out of the shell, and separating the pole ear from the battery cell. Due to the strong friction between the shell and the battery cell, this method of removing the battery cell is easy to pull the pole ear off during operation, resulting in the battery cell being unable to be pulled out normally, and after the battery cell is removed, a saw blade is needed to saw the pole ear off the battery cell, thereby reducing the efficiency of battery recycling. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing single battery recycling line that the tabs are easily pulled off when taking out the battery cells and the efficiency of separating the battery cells and the tabs is low, and to provide a single battery recycling line that cuts off the tabs by punching to improve the success rate and recycling efficiency of the battery cells.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A single battery recycling line, comprising the following devices:

[0006] The material-digging conveying device comprises a material-digging conveying line and a material-digging mechanism, wherein the material-digging conveying line comprises a fixed rail and a movable rail extending along the X-axis and arranged opposite to each other, wherein the movable rail can be controlled to approach or move away from the fixed rail, and the material-digging mechanism comprises a plurality of diverting rods arranged at intervals along the extension direction of the fixed rail at a preset interval, wherein the plurality of diverting rods can swing up and down relative to the material-digging conveying line, and can synchronously reciprocate relative to the material-diverting conveying line, and when the plurality of diverting rods can be controlled to swing downward to above the material-diverting conveying line, the batteries located on the material-diverting conveying line are intermittently pushed downstream;

[0007] The shell cutting device and the tab cutting device are sequentially arranged along the conveying direction of the material conveying line:

[0008] The shell cutting device comprises a first cutting mechanism arranged on the side of the material feeding conveying line, wherein the first cutting mechanism is provided with a movable first saw blade and a second saw blade, wherein the first saw blade and the second saw blade can be controlled to move to opposite sides of the battery in the conveying direction, and cut the battery shell along a track perpendicular to the conveying direction;

[0009] The tab cutting device comprises a second cutting mechanism arranged at the side of the material feeding conveyor line, the second cutting mechanism comprises a material pressing module, a ring cutting module and a cutting module, the material pressing module is provided with a second cutting pressing plate which can move up and down, the ring cutting module is provided with a third saw blade which moves around a preset track, the cutting module is provided with a cutter which can move up and down, the second cutting pressing plate is used to press the upper side of the battery downward, the third saw blade is used to ring cut the battery shell to form a ring slit corresponding to the tab, the cutter is used to longitudinally punch the battery at a position corresponding to the ring slit, so that the battery is cut at the ring slit and an opening is formed at the end of the battery shell;

[0010] The core-pulling device comprises a core-pulling conveyor line connected with the material-pulling conveyor line, the core-pulling conveyor line comprises an adjustment table arranged in the downstream direction of the material-pulling conveyor line, and a second transfer mechanism connecting the material-pulling conveyor line and the adjustment table, the second transfer mechanism is provided with a second gripper which can be opened and closed along the Y-axis direction, the adjustment table can be lifted and lowered along the Z-axis direction, and also comprises a clamping mechanism arranged on one side of the adjustment table in the Y-axis direction, and a core-pulling mechanism arranged on the opposite side of the clamping mechanism, the clamping mechanism can be controlled to move along the Y-axis direction, and is provided with a first gripper and a second gripper with opening and closing directions vertically staggered, the first gripper opens and closes along the X-axis direction, and the second gripper opens and closes along the Z-axis direction, the core-pulling mechanism is provided with a third gripper which can move along the Y-axis direction, and the third gripper can open and close along the Z-axis direction;

[0011] The second gripper is used to grab the battery on the material conveyor line from the Y-axis direction and transfer it to the adjustment table. The adjustment table rises or falls a compensation distance according to the size of the battery in the Z-axis direction, so that the center of the battery in the Z-axis direction is aligned with the gripping reference of the third gripper. The gripping mechanism approaches the battery along the Y-axis, and controls the second gripper and the first gripper in turn to clamp the end of the battery relative to its opening from the Z-axis and X-axis directions respectively. The third gripper can be controlled to approach the battery along the Y-axis direction, and extend into the opening of the battery in an open state, then close to clamp the battery cell, and then move in the opposite direction along the Y-axis direction.

[0012] Compared with the prior art, the single cell battery recycling line provided by the present invention changes the existing battery recycling process, uses a shell cutting device to first cut the opposite sides of the shell to initially loosen the battery cell and the shell, and then cuts a circular slit around one end of the shell corresponding to the pole ear on the pole ear cutting device. Under the protection of the shell, the battery is pressed downward by a pressure plate, and the position of the circular slit is punched out by a cutter to separate the battery cell from the pole ear, and then the battery cell is pulled out by a core pulling device. The above-mentioned arrangement can accelerate the separation speed of the pole ear and the battery cell, thereby improving the efficiency of battery recycling, avoiding the existing practice of pulling the battery cell out of the shell by the pole ear, and improving the success rate of battery cell recycling. In addition, the present invention also transmits the battery by a lever. Compared with the traditional conveyor belt, the present invention uses a fixed travel distance of the lever, so that the battery can be accurately pushed to the preset position each time without the need to additionally set up a mechanism for stopping the battery, thereby improving the accuracy of battery transfer and reducing equipment costs.

[0034] The specific implementation of the present invention is described below with reference to the accompanying drawings.

[0035] See also Figure 1 , Figure 2 , Fig.18 The present embodiment provides a single battery recycling line for disassembling and recycling a battery 100, wherein the battery 100 includes a housing 101 and a battery cell 104 located inside the housing 101, wherein one end of the housing 101 is connected to a tab of the battery cell. Fig.29 As shown, the recycling process involved in this embodiment includes first cutting the outer shell 101 along its length direction on opposite sides to form an outer shell slit 103, and then cutting an annular slit 102 on the outer shell 101 around one end of the outer shell 101 connected to the battery cell, and then using a cutter d41 to punch out the battery cell and the tab together with the outer shell 101 at the position of the annular slit 102, so that the battery 100 is divided into a main body 1.1 and a main body 1.2. The main body 1.2 is directly recycled, and the main body 1.1 connected to the battery cell 104 is recycled by extracting the battery cell 104 from the outer shell 101 and recycling it, and at the same time recycling the remaining outer shell 101, thereby completing the recycling process of a battery 100.

[0036] See also Figure 2 The single cell recycling line includes a feeding device a, a material conveying device b, a shell cutting device c, a tab cutting device d, and a core pulling device e. The above devices are described below respectively.

[0037] Feeding device a:

[0038] See also Figures 2 to 4 The loading device a includes a loading frame a1, a loading conveyor line a2 arranged on the loading frame a1, a first transfer mechanism a3 and a blocking mechanism a4. The loading conveyor line a2 has a loading end a01 and a loading end a0, which is used to transfer the batteries 100 from the loading end a01 to its loading end a0 in sequence. The blocking mechanism a4 includes a liftable baffle a41 arranged on the side of the loading end a0. The battery 100 conveyed to the loading end a0 can be stopped by the raised baffle a41.

[0039] See also Figures 3 to 6 A first guide plate a21 extending along the conveying direction is provided on one side of the feeding conveying line a2, and a second guide plate a22 parallel to the first guide plate a21 and capable of approaching or moving away from the first guide plate a21 is provided on the opposite side. Figure 3 The first guide plate a22 extends in the X-axis direction, the second guide plate a22 can move in the Y-axis direction, the feeding end a0 of the feeding conveyor line a2 is provided with a first sensor a23, the first transfer mechanism a3 is provided with a first gripper a31 provided on the feeding end a0, the first gripper a31 includes a first clamping component a32 provided on the same side of the first guide plate a21, and a second clamping component a33 provided on the other side relative to the first clamping component a32, the second clamping component a33 is provided with a second sensor a331 for detecting toward one side of the first clamping component a32, and the second clamping component a33 is provided with a second sensor a331 for detecting toward one side of the first clamping component a32. The first clamping assembly a33 and the first clamping assembly a32 can approach or move away from each other along the Y-axis direction. When the battery 100 moves to be detected by the first sensor a23, the baffle a41 rises to prevent the battery 100 from continuing to run. At this time, the feeding conveyor line a2 stops, and the battery 100 is located between the first clamping assembly a32 and the second clamping assembly a33. The second clamping assembly a33 and the first clamping assembly a32 approach each other, and after the second sensor a331 scans the side surface of the battery 100, the second clamping assembly (a32) stops to clamp the battery 100. It should be noted that the above-mentioned feeding conveyor line a2 is preferably a conveyor belt, and the first sensor a23 and the second sensor a331 both use existing reflective photoelectric sensors. By adjusting the scanning range of the photoelectric sensor, it can be ensured that once the photoelectric sensor senses a signal, the second clamping assembly a33 has been clamped in place and the battery 100 has moved to the feeding end a0.

[0040] See also Figure 6In a specific embodiment, the first gripper a31 includes an upper bracket a311, and a first clamping cylinder a321 and a second clamping cylinder a332 are provided at the bottom of the upper bracket a311. The first clamping assembly a32 includes a first clamping block a322 driven by the first clamping cylinder a321, and the second clamping assembly a33 includes a second clamping block a333 driven by the second clamping cylinder a332. A detection notch a334 is provided at the bottom of the second clamping block a333. The second sensor a331 is provided on the outer side of the second clamping block a333, and transmits a detection signal toward one side of the first clamping assembly a32 through the detection notch a334.

[0041] See also Figure 4 The first gripper a31 also includes a protective cover a312 arranged on the outside of the upper bracket a311, and the protective cover a312 is equipped with a side baffle a313 and a front baffle a314 connected to the front side of the side baffle a313, which is used to protect the above-mentioned clamping components such as the clamping cylinder to prevent the downstream cutting device from damaging the above-mentioned components due to the detached battery casing 101 flying out when working.

[0042] See also Figure 3 The feeding conveyor line a2 further comprises a gripper driving mechanism a5 arranged on the feeding frame a1 for driving the first gripper a31. The gripper driving mechanism a5 preferably adopts an existing rodless cylinder.

[0043] join Figure 4 The material blocking mechanism a4 also includes a material blocking cylinder a42 installed on the feeding frame a1, and the output shaft of the material blocking cylinder a42 is arranged toward the upper side and connected to the baffle a41.

[0044] See also Figure 5 The loading frame a1 is provided with a plurality of adjustment seats a24 at intervals along the extension direction of the second guide plate a22, and each adjustment seat a24 is provided with an adjustment rod a25 that can move in a direction perpendicular to the second guide plate a22, that is, the adjustment rod a25 can move along the Y-axis direction in the figure, and the adjustment seat a24 is also provided with an adjustment nut a26 for locking the adjustment rod a25, and the adjustment rod a25 is connected to the second guide plate a22, and the position of the adjustment rod a25 can be unlocked or locked by the adjustment nut a26 to adjust the distance between the second guide plate a22 and the first guide plate a21, so as to adapt to batteries 100 of different specifications.

[0045] The loading device a is provided with a second sensor a331 on the second clamping assembly a33. When the battery 100 moves to the loading end a0, the baffle a41 rises to stop the battery 100, so that the battery 100 stays between the first clamping assembly a32 and the second clamping assembly a33. In actual use, the first clamping assembly a32 is pre-set closer to the battery 100 relative to the second clamping assembly a33, that is, the battery 100 is closer to the first clamping assembly a32. The above setting only requires that the battery 100 is placed closer to the first clamping assembly a32 when it is placed at the loading end. The second clamping component a33 and the first clamping component a32 are close to each other, that is, they move toward the side surface of the battery 100 respectively. When the second sensor a331 detects the side surface of the battery 100, it means that the second clamping component a33 has been clamped on the side surface of the battery 100. Since the first clamping component a32 is closer to the battery, the first clamping component a32 must also be clamped on the side surface of the battery 100. Therefore, the battery 100 that has been clamped by the first gripper a31 can then be loaded and transferred. The battery loading device set up as above can adapt to the size specifications of the battery without manually adjusting the parameters of the gripper. It not only optimizes the loading operation, but also can adapt to batteries of various specifications within a certain size range, which is convenient for production change, thereby improving the efficiency of battery recycling.

[0046] Material conveying device b:

[0047] See also Figure 7 and Figure 8 The material feeding and conveying device b includes a material feeding and conveying line b1 and a material feeding mechanism b2. The material feeding and conveying line b1 includes a fixed rail b11 and a movable rail b12 extending along the X-axis and arranged opposite to each other. The movable rail b12 can be controlled to approach or move away from the fixed rail b11. The battery 100 clamped by the first transfer mechanism a3 from the loading conveying line a2 will be transferred to the support on the movable rail b12 and the fixed rail b11, and will be moved in the downstream direction by the material feeding mechanism b2.

[0048] See also Figure 7 and Fig. 9 The material-diverting mechanism b2 includes a plurality of diverting rods b21 arranged at preset intervals along the extension direction of the fixed rail b11. The plurality of diverting rods b21 can swing up and down relative to the material-diverting conveyor line b1, and can synchronously reciprocate relative to the material-diverting conveyor line b1. The plurality of diverting rods b21 can be controlled to swing downward to be horizontally placed above the material-diverting conveyor line b1, and translate toward the downstream direction to push the battery 100 located on the material-diverting conveyor line b1. After completing a material diverting, the diverting rod b21 swings upward and translates in the opposite direction to achieve reset, and this is repeated to intermittently divert the battery 100.

[0049] See also Figure 8 The material-feeding conveyor line b1 also includes a first driving component b13 for driving the movable rail b12 to move. The first driving component b13 includes a driving rod b131 arranged parallel to the movable rail b12, a first driving mechanism b132 driving the driving rod b131 to rotate, and a plurality of screw rods b133 arranged along the movable direction of the movable rail b12. The end of each screw rod b133 is connected to a driven bevel gear b134. The driving rod b131 is respectively provided with an active bevel gear b135 meshing with the driven bevel gear b134. Each screw rod b133 is respectively threadedly connected to the movable rail b12. The driving method of the movable rail b12 has a simple structure.

[0050] See also Figure 8 The material-selecting conveying line b1 further includes a plurality of guide rails b14 fixedly arranged below the movable rail b12, the guide rails b14 extending along the movable direction of the movable rail b12, and the movable rail b12 being slidably connected to the guide rails b14. The guide rails b14 can improve the rigidity of the movable rail b12.

[0051] See also Figure 8 , the movable rail b12 and the fixed rail b11 are both formed by connecting several parts in sequence, wherein the parts of the movable rail b12 and the fixed rail b11 corresponding to the shell cutting device c are both formed by connecting the left movable segment b101, the fixed segment b102 and the right movable segment b103 in sequence, and the left movable segment b101 and the right movable segment b103 can be raised and lowered relative to the fixed segment b102. Since the size of the battery 100 varies, when cutting a battery 100 of a smaller size, there is a possibility that the cutting tool will interfere with the movable rail b12 and the fixed rail b11, therefore, at the part of the fixed rail b11 and the movable rail b12 corresponding to the cutting position, the rail is made into a segmented structure, and before the cutting tool is fed, the rail below the battery 100 remains stationary, while the rails on the left and right sides are lowered to avoid the cutting tool and prevent the tool from hitting the tool.

[0052] See also Figure 8 The portion of the fixed rail b11 corresponding to the tab cutting device d is provided with a cutting recess b104 recessed inwardly, and the outer side of the cutting recess b104 is provided with a flippable anvil b105, and the anvil b105 is provided with an avoidance channel b106. By setting the cutting recess b104, the battery can be provided with certain special cutting on the cutting recess b104, such as circular cutting around the battery 100, and the flippable anvil b105 can provide effective support for the battery 100 during punching, and the avoidance channel is used for the downward movement of the punching tool.

[0053] See also Fig. 9The material shifting mechanism b2 also includes a swinging mechanism b22, and lever assemblies are respectively provided on opposite sides of the swinging mechanism b22, each lever assembly includes a cross bar group b210, a swinging gear b211 connected to the cross bar group b210 and located near the swinging mechanism b22, and a first support b212 and a second support b213 arranged on both sides, the cross bar group b210 is rotatably supported on the first support b212 and the second support b213, and is provided with a plurality of parallel cross bars b214, and the plurality of levers b21 are arranged at intervals on the cross bar group b210, and the lever assemblies corresponding to each side of the swinging mechanism b22 are respectively provided with a swing rack b221 meshing with the swing gear b211, and a swing cylinder b222 driving the swing rack b221 to rise and fall. The above-mentioned cross bar group b210 for fixing the lever b21 is configured with multiple cross bars b214, thereby improving the rigidity and strength of the lever assembly. The transmission method between the swing mechanism b22 and the lever assembly adopts a gear rack structure, which has a fast and smooth response, precise transmission, strong bearing capacity and can provide a certain self-locking effect.

[0054] See also Fig. 9 A third sensor b215 is provided at the end of each shifting rod b21 on the side facing downstream. When the third sensor b215 does not detect the existence of a battery 100 in the downstream direction, it means that no battery 100 is being cut in the downstream direction. Therefore, the controller can command the shifting mechanism b2 to reset immediately and continue to push the battery 100 in the downstream direction, thereby saving time and avoiding waiting.

[0055] See also Fig. 9 and Fig.10 The material-moving mechanism b2 also includes a limiting plate b23 connected to the cross bar group b210 and located at one end relative to the swing gear b211. The second support b213 is arranged on a side close to the limiting plate b23. The limiting plate b23 is provided with a limiting portion b231 radially protruding relative to its rotation center. The top and side of the second support b213 are respectively provided with a first stopper b232 and a second stopper b233 which can move within the rotation trajectory of the limiting portion b231.

[0056] See also Fig.10In a specific embodiment, the top and side of the second support b213 are both provided with a rotating cylinder b24, and the first stopper b232 and the second stopper b233 are driven to rotate by the corresponding rotating cylinder b24, so as to selectively rotate to the rotation track range of the limiting part b231, thereby blocking the rotation of the limiting part b231. When the lever b21 swings upward, the first stopper b232 located at the top can be driven to move to the lower side of the limiting part b231 along its rotation track, thereby blocking the lever b21 from accidentally swinging downward, especially in response to a sudden power outage; when the lever b21 swings downward, the second stopper b233 located at the side can be driven to move to the upper side of the limiting part b231 along its rotation track, thereby blocking the lever b21 from jumping up and down when the battery 100 is moved.

[0057] See also Fig. 9 The material shifting mechanism b2 also includes a power mechanism b25, which includes a driving cylinder b251 and a shifting rail b252 extending along the conveying direction of the battery 100. The swinging mechanism b22 and the shifting rod assembly are slidably arranged on the shifting rail b252. The driving cylinder b251 is fixedly arranged on the shifting rail b252, and its output end is connected to the swinging mechanism b22 to drive the swinging mechanism b22 and the shifting rod assembly to slide along the shifting rail b252.

[0058] Shell cutting device c:

[0059] See also Figure 2 , Fig.11 and Fig.12 , Fig.29 The shell cutting device c includes a first cutting mechanism c1 arranged on the side of the material conveying line b1, and the first cutting mechanism c1 is equipped with a movable first saw blade c11 and a second saw blade c12. The first saw blade c11 and the second saw blade c12 can be controlled to move to the opposite sides of the battery 100 in the conveying direction, and cut the shell 101 of the battery 100 along a trajectory perpendicular to the conveying direction, thereby forming a shell slit 103.

[0060] See also Fig.11 and Fig.12The shell cutting device c is also configured with a first distance sensor c21 and a second distance sensor c22 which are arranged relatively to each other. The first distance sensor c21 moves following the first saw blade c11, and the second distance sensor c22 moves following the second saw blade c12. The first distance sensor c21 and the second distance sensor c22 can be controlled to emit detection signals in their respective relative directions. The two are respectively used to scan the opposite sides of the shell 101 of the battery 100 along the cutting paths of the first saw blade c11 and the second saw blade c12 to obtain the cutting depths of the first saw blade c11 and the second saw blade c12 on the cutting paths. Since the recycled battery 100 is a waste battery, the shell 101 will be deformed due to the bulging of the battery. Therefore, the deformation of the battery shell 101 is first collected by the first distance sensor c21 and the second distance sensor c22, so as to calculate the dynamic cutting amount of the cutting path, so as to accurately cut the shell 101 and avoid cutting the battery cell 104. The above-mentioned distance sensor adopts the existing technology, and its specific collection method is not the invention point of the present invention, and is not explained here.

[0061] See also Figures 11 to 14The first cutting mechanism c1 includes a first cutting and feeding mechanism c13, a second cutting and feeding mechanism c14 and a third cutting and feeding mechanism c15. The first cutting and feeding mechanism c13 includes a first cutting and feeding screw rod c131 horizontally arranged above the material-diverting conveying line b1, a first cutting and feeding bracket c132 threadedly connected to the first cutting and feeding screw rod c131, and a first cutting motor c133 driving the first cutting and feeding screw rod c131 to rotate.

The second cutting and feeding mechanism c14 includes a second cutting and feeding screw rod c141 longitudinally arranged on the first cutting and feeding bracket c132, a second cutting and feeding bracket c142 threadedly connected to the second cutting and feeding screw rod c141, and a second cutting motor c143 driving the second cutting and feeding screw rod c141 to rotate. The third cutting and feeding mechanism c15 includes a second cutting and feeding bracket c142 arranged on two opposite sides of the second cutting and feeding bracket c142. The third cutting feed screw c151 is disposed on the side and extends respectively along the conveying direction of the battery 100, the third cutting motor c152 drives the third cutting feed screw c151 to rotate, and the third cutting feed bracket c153 is threadedly connected to the third cutting feed screw c151. The third cutting feed bracket c153 is respectively provided with a saw blade driving mechanism c16 for driving the corresponding first saw blade c11 or second saw blade c12 to rotate. The rotation of the first cutting feed screw c131 can drive the second cutting feed mechanism c14 and the third cutting feed mechanism c15 to approach or move away from the material conveying line b1 in a direction perpendicular to the material conveying line b1. The rotation of the second cutting feed screw c141 can drive the third cutting feed mechanism c15 to rise and fall, thereby adjusting the height of the first saw blade c11 and the second saw blade c12 according to the specifications of the battery 100. The rotation of the third cutting feed screw c151 can drive the first saw blade c11 and the second saw blade c12 to approach or move away from the battery 100 in the direction of battery conveying.

[0062] See also Fig.14 The first distance sensor c21 and the second distance sensor c22 are respectively loaded on the corresponding third cutting feeding bracket c153 through the scanning bracket c20.

[0063] See also Fig.11 and Fig.12 As an improved solution, it also includes a first cutting plate c16 that can be raised and lowered and is arranged below the first cutting mechanism c1. The first cutting plate c16 can be controlled to descend and press against the top of the battery 100, thereby preventing the battery 100 from moving during cutting.

[0064] The shell cutting device c is provided with distance sensors on the outside of the two saw blades. Before the saw blades cut the shell 100, the first saw blade c11, the first distance sensor c21, the second saw blade c12, and the second distance sensor c22 move to the opposite sides of the battery 100, and first control the first distance sensor c21 and the second distance sensor c22 along the cutting path, that is, first scan the side surface of the shell 101 along the Y-axis direction on the opposite sides of the battery 100, so as to obtain the distance from the shell 101 on the cutting path, and after determining the dynamic cutting depth of the corresponding saw blades, the first saw blade c11 and the second saw blade c12 are controlled to move in the opposite direction, and the shell 101 is cut according to the dynamic cutting depth, so as to control the cutting depth according to the undulating state of the shape of the surface of the battery shell 100, to ensure that the shell 101 is cut without cutting the battery cell, and to improve the accuracy of the shell 101 cutting.

[0085] The core pulling device e achieves the fixation of the battery 100 and the clamping of the battery cell 104 by setting a clamping mechanism e4 and a core pulling mechanism e5. Specifically, before extracting a battery cell of a certain specification, the height of the battery can be determined. Therefore, the adjustment seat e2 rises or falls a compensation distance h according to the height of the battery before each extraction of the battery cell, thereby adjusting the battery 100 to correspond to the clamping reference of the third gripper e6. Since the position of the battery 100 in the Z-axis direction has been determined at this time, the second gripper e42 is first controlled to clamp the end of the battery 100 opposite to its opening from the Z-axis direction, thereby fixing the coordinates of the battery in the Z-axis direction, and then the first gripper e41 is controlled to further fix the position of the battery 100 from the X-axis direction, thereby limiting the freedom of the battery 100 from four directions, so that one side of the opening of the battery 100 is aligned with the clamping reference of the third gripper e6, thereby ensuring the accuracy of clamping the battery cell 104. Compared with the prior art, the core pulling device of the present invention avoids directly pulling the battery cell out of the casing by pulling the pole tab, thereby improving the success rate of battery cell extraction, and the single cell battery recycling line using this core pulling device does not need to cut the pole tab after extracting the battery cell. On the contrary, the pole tab can be directly removed before extracting the battery cell.

[0090] See also Fig.29 The single cell recycling line provided by the present invention changes the existing recycling process of the battery 100. The shell cutting device c is used to first cut the opposite sides of the shell 101 to initially loosen the battery cell from the shell 101. Then, the tab cutting device d is used to first cut an annular slit 102 around one end of the shell 101 corresponding to the tab. Under the protection of the shell 101, the battery 100 is pressed downward by the pressing plate, and the position of the annular slit 102 is punched out by the cutter d41 to separate the battery cell from the tab. Then, the battery cell is pulled out by the core pulling device e. The above arrangement can speed up the separation of the tab and the battery. The separation speed of the core is improved, thereby improving the efficiency of battery 100 recycling, avoiding the existing practice of using the pole ear to pull the battery cell 104 out of the shell 101, and improving the success rate of battery cell 104 recycling. In addition, the present invention also transfers the battery 100 through the lever b21. Compared with the traditional conveyor belt, the present invention uses the fixed travel distance of the lever b21 to accurately move the battery 100 to the preset position each time without the need to additionally set up a mechanism for stopping the battery 100, thereby improving the accuracy of battery 100 transfer and reducing equipment costs.
