[0062] Please refer to Figure 1-Figure 9 , this embodiment provides a battery cell separation device 100, the battery cell separation device 100 includes a workbench 110, a battery cell transfer unit 130, a battery cell separation unit 150, a battery cell transfer robot 170 and a battery cell removal unit 190;

[0063] The cell transfer unit 130 is movably connected to the workbench 110 along a first preset direction and has at least a loading position (such as Fig. 9 The position indicated by the mark A) and the unloading position (as shown in Fig. 9 The position indicated by mark B in the figure);

[0064] The cell transfer robot 170 is connected to the workbench 110, and the cell transfer robot 170 is used to grab the cell 10 on the cell transfer unit 130 at the loading position and transfer it to the cell separation unit 150, and after the cell separation unit 150 separates the cell 10 into the winding core 20, transfer the winding core 20 to the cell transfer unit 130 at the loading position;

[0065] The battery cell removing unit 190 is used to grab and remove the winding core 20 on the battery cell transfer unit 130 at the unloading position.

[0066] Please refer to Figure 1-Figure 9 , the working principle of the battery cell separation device 100 is:

[0067] The cell separation device 100 includes a workbench 110, a cell transfer unit 130, a cell separation unit 150, a cell transfer robot 170 and a cell removal unit 190; wherein the cell transfer unit 130 is used to carry the cell 10 to be separated and the separated winding core 20, so as to facilitate the cell transfer robot 170 and the cell removal unit 190 to grab, thereby improving efficiency; the cell separation unit 150 is used to separate the cell 10; and the cell removal unit 190 is used to grab the separated winding core 20 and remove it;

[0068] Specifically, when configuring the cell transfer unit 130, it is adopted that it is movably connected to the workbench 110 along the first preset direction, and has at least a loading position and a unloading position, so that when it is at the loading position, it can receive the cell 10 to be separated, and when it is at the unloading position, it is convenient for the cell removal unit 190 to grab the winding core 20;

[0069] The cell transfer robot 170 is connected to the workbench 110, and the cell transfer robot 170 is used to grab the cell 10 on the cell transfer unit 130 at the loading position and transfer it to the cell separation unit 150, and to transfer the core 20 to the cell transfer unit 130 at the loading position after the cell separation unit 150 separates the cell 10 into the core 20; thus, through the setting of the cell transfer robot 170, it is possible to move between the cell transfer unit 130 at the loading position and the cell separation unit 150, so as to grab and transfer the cell 10 to be separated, and grab and transfer the core 20 separated from the cell 10, so as to improve the transfer efficiency of the cell 10 and the core 20, thereby improving the separation efficiency of the cell 10;

[0070] The battery cell removing unit 190 is used to grab and remove the winding core 20 on the battery cell transfer unit 130 at the unloading position.

[0071] In summary, the battery cell separation device 100 is easy to operate, can improve the separation efficiency of the battery cells 10, and can prevent the battery cells 10 from being damaged during the separation process, thereby improving the safety and consistency of separation and reducing the separation cost.

[0072] It should be noted that, in this embodiment, the first preset direction, the second preset direction, and the third preset direction are perpendicular to each other as an example. Specifically, the first preset direction, the second preset direction, and the third preset direction correspond to the arrow X, arrow Y, and arrow Z directions in the diagram, respectively.

[0073] For further information, please refer to Figure 1-Figure 9 In this embodiment, when configuring the cell transfer unit 130, it can be known from the above content that its function is to carry the cell 10 to be separated and the separated winding core 20, so as to facilitate the cell transfer robot 170 and the cell removal unit 190 to grasp, thereby improving efficiency; therefore, in order to enable it to change its position between the loading position and the unloading position, and to be able to position the cell 10 and the winding core 20, the cell transfer unit 130 includes a first linear motion module 131, a cell platform 132 and a first positioning component 133;

[0074] The first linear motion module 131 is connected to the workbench 110, the battery platform 132 is connected to the first linear motion module 131, and the first linear motion module 131 is connected to the battery platform 132. The first linear motion module 131 is used to drive the battery platform 132 to move along a first preset direction to change the position between the loading position and the unloading position;

[0075] The first positioning assembly 133 is connected to the battery cell platform 132 , and is used to position or clamp the battery cell 10 or the winding core 20 placed on the battery cell platform 132 .

[0076] Therefore, during use, the first linear motion module 131 can drive the cell platform 132 to move relative to the workbench 110 along the first preset direction, thereby changing the position between the loading position and the unloading position; it should be noted that the loading position and the unloading position can be two spaced position points in the stroke of the first linear motion module 131 along the first preset direction, or can be the two ends of its stroke;

[0077] While the first linear motion module 131 drives the battery cell platform 132 to move, or when it is in the loading position or the unloading position, the first positioning component 133 can be used to position or clamp the battery cell 10 or the winding core 20 placed on the battery cell platform 132, so as to improve the stability of the battery cell 10 or the winding core 20 on the battery cell platform 132.

[0078] Based on this, when configuring the first linear motion module 131, it can adopt a linear motion mechanism in the prior art, such as: a cylinder, a hydraulic cylinder, a linear motor and a screw slider module, etc., or other types of linear motion modules.

[0079] When configuring the first positioning component 133, its purpose is to play a role in positioning the battery cell 10 or the winding core 20, or to play a role in clamping. Therefore, the first positioning component 133 includes a first battery cell positioning cylinder 134 and a first positioning plate 135. The first battery cell positioning cylinder 134 is connected to the battery cell platform 132, and the first positioning plate 135 is connected to the first battery cell positioning cylinder 134. The first battery cell positioning cylinder 134 is used to drive the first positioning plate 135 to move along the second preset direction to abut against the battery cell 10 or the winding core 20 on the battery cell platform 132; wherein the first preset direction is perpendicular to the second preset direction.

[0080] With such a setting, the first positioning cylinder can be used to drive the first positioning plate 135 to move, thereby causing it to move relative to the battery cell platform 132, thereby abutting against the battery cell 10 or the winding core 20 placed on the battery cell platform 132 to position it; and on this basis, the number of first positioning components 133 can be increased, that is, a first positioning plate 135 is distributed on both sides of the opposite sides of the battery cell platform 132, thereby, one of the two movable first positioning cylinders can be used to drive the corresponding first positioning plate 135 to move, thereby clamping the battery cell 10 or the winding core 20 placed on the battery cell platform 132.

[0081] For further information, please refer to Figure 1-Figure 11In this embodiment, when the cell transfer manipulator 170 is configured, its function is to grab the cell 10 or the winding core 20 and transfer its position. Specifically, the cell transfer manipulator 170 includes a movable frame 171, a second linear motion module 172, a gripper lifting cylinder 173, two gripper cylinders 174 and two grippers 175;

[0082] The movable frame 171 is connected to the workbench 110, the second linear motion module 172 is connected to the movable frame 171, and the clamping claw lifting cylinder 173 is connected to the second linear motion module 172; the two clamping claw cylinders 174 are connected to the clamping claw lifting cylinder 173, and the clamping claw lifting cylinder 173 is used to drive the two clamping claw cylinders 174 to move along the third preset direction; the two clamping claws 175 are respectively connected to the two clamping claw cylinders 174, and the two clamping claw cylinders 174 are respectively used to drive the corresponding clamping claws 175 to move along the first preset direction or the second preset direction to clamp or release the battery cell 10 or the winding core 20;

[0083] The second linear motion module 172 is used to drive the clamping claw lifting cylinder 173 to move along a second preset direction so as to change the position between directly above the battery cell platform 132 at the loading position and directly above the battery cell separation unit 150 .

[0084] Through the above-mentioned structural setting, in this embodiment, the second linear motion module 172 can drive the clamping claw lifting cylinder 173 to move in the second preset direction, and in the process of its movement along the second preset direction, it can change its position between directly above the battery platform 132 at the loading position and directly above the battery cell separation unit 150, that is, in this way, it can drive the two clamping claw cylinders 174 and the two clamping claws 175 for grabbing the battery cell 10 or the winding core 20 relative to the battery platform 132 and the battery cell separation unit 150. The element 150 moves, and when the two clamping claw cylinders 174 and the two clamping claws 175 move to the top of the battery cell platform 132, the clamping claw lifting cylinder 173 drives it to move in the third direction, and then it can move down to grab the battery cell 10 on the battery cell platform 132; and when it is located directly above the battery cell separation unit 150, it can release the grabbed battery cell 10 and also grab the battery cell 10 after the battery cell 10 is separated; in addition, after it grabs the winding core 20, it can also release it to the battery cell platform 132;

[0085] Under the action of the second linear module and the clamp lifting cylinder 173, the two clamps 175 that can perform the grasping action can be driven to move in the second preset direction and the first preset direction respectively with the two clamp cylinders 174, so that it can be adjusted to the top of the battery cell platform 132 or to the top of the battery cell separation unit 150; on this basis, the two clamp cylinders 174 can respectively drive the corresponding clamps 175 to move, so that the two clamps 175 are close to each other to grasp the battery cell 10 or the winding core 20, and when the two clamps 175 are moved away from each other, the grasped battery cell 10 or the winding core 20 can be released. It should be noted that adjusting it to the top of the battery cell platform 132 means adjusting it to the top of the battery cell platform 132 in the loading position.

[0086] When configuring the second linear motion module 172, it can adopt a linear motion mechanism in the prior art, such as: a cylinder, a hydraulic cylinder, a linear motor and a screw slider module, etc., or other types of linear motion modules.

[0087] For further information, please refer to Figure 1-Figure 15 In this embodiment, when the cell separation unit 150 is configured, its function is to separate the cell 10 into the winding core 20, and in the specific operation, its separation action is to operate the cutter 162 to cut the adhesive tape on the outer side of the cell 10, so as to eliminate the connection effect of the adhesive tape on the stacked winding core 20; therefore, when the cell separation unit 150 is configured, it includes a separation seat 151, a lifting and lowering movement module 152, a separation platform 153, a second positioning component 154 and at least one adhesive tape cutting component 155;

[0088] The separation seat 151 is connected to the workbench 110, the lifting movement module 152 is connected to the separation seat 151, and the separation table 153 is connected to the lifting movement module 152, and the lifting movement module 152 is used to drive the separation table 153 to move along the third preset direction; the second positioning component 154 is connected to the separation table 153, and the second positioning component 154 is used to position or support the battery cell 10 or the winding core 20 on the separation table 153; the tape cutting component 155 is connected to the workbench 110, and the tape cutting component 155 is used to cut the tape on the outside of the battery cell 10; wherein the first preset direction, the second preset direction and the third preset direction are perpendicular to each other.

[0089] Therefore, through the above-mentioned structural setting, the height of the separation table 153 can be adjusted by moving the lifting motion module 152 in the third preset direction, so that it is at a suitable height for receiving the battery cell 10, or at a height that is convenient for the battery cell transfer robot 170 to grasp it. It can also make the battery cell 10 placed on the separation table 153 at a height that can be used for tape cutting by the tape cutting component 155.

[0090] It should be noted that this embodiment takes the device configured with three tape cutting components 155 as an example. The three tape cutting components 155 are respectively the first tape cutting component 163, the second tape cutting component 164 and the third tape cutting component 165. Moreover, the first tape cutting component 163 and the second tape cutting component 164 are located on both sides of the battery cell 10, and the third tape cutting component 165 is located at the head of the battery cell 10. The working principles of the first tape cutting component 163, the second tape cutting component 164 and the third tape cutting component 165 are the same. Therefore, this article takes the working process of one of the tape cutting components 155 as an example for explanation.

[0091] When configuring the lifting motion module 152, it can adopt a linear motion mechanism in the prior art, such as: a cylinder, a hydraulic cylinder, a linear motor and a screw slider module, etc., or other types of linear motion modules.

[0092] When the second positioning component 154 is configured, its function is to position or clamp the battery cell 10 or the winding core 20 located on the separation table 153, so as to prevent the battery cell 10 or the winding core 20 from being displaced relative to the separation table 153 under the action of the tape cutting component 155 or the battery cell transfer robot 170 when the battery cell 10 is being cut or the battery cell 10 is being separated. Therefore, the second positioning component 154 is configured, and the second positioning component 154 includes two second battery cell positioning cylinders 156 and two second positioning plates 157; the two second battery cell positioning cylinders 156 are both connected to the separation table 153, and the two second positioning plates 157 are respectively connected to the two second battery cell positioning cylinders 156, and each second battery cell positioning cylinder 156 is used to drive the corresponding second positioning plate 157 to move along the first preset direction or the second preset direction to abut against the battery cell 10 or the winding core 20 on the separation table 153; wherein the two second positioning plates 157 are arranged relatively along the first preset direction or the second preset direction.

[0093] That is, the battery cell 10 can be clamped by such a setting; it should be noted that when the battery cell 10 or the core 20 is clamped by the two second positioning plates 157 mentioned above, its function is to maintain the position of the battery cell 10 or the core 20, and in this process, in order to avoid interference between the second positioning plates 157 and the tape cutting assembly 155 or the battery cell transfer robot 170, therefore, taking the battery cell 10 with two layers of stacked cores 20 as an example, the position of the second positioning plate 157 clamping the battery cell 10 is located on the outside of the lower core 20 of the battery cell 10, and the tape cutting assembly 155 cuts the area between the two layers of core 20 of the battery cell 10 when cutting the tape, and the battery cell transfer robot 170 first transfers the upper core 20 and then transfers the lower core 20 when transferring the core 20.

[0094] When configuring the adhesive tape cutting assembly 155, in order to facilitate the separation of the battery cell 10, taking the example that each adhesive tape cutting assembly 155 is used to cut the adhesive tape on one side of the battery cell 10, it is necessary to set the adhesive tape cutting assembly 155 according to the adhesive tape on the outer side of the battery cell 10; and in this embodiment, three groups of adhesive tape cutting assemblies 155 are configured, and the three groups are distributed on three different sides of the battery cell 10, and each adhesive tape cutting assembly 155 is used to cut the adhesive tape on one side of the battery cell 10;

[0095] The following is an example of the structure of a single adhesive tape cutting assembly 155. Specifically, the adhesive tape cutting assembly 155 includes a cutting seat 158, a third linear motion module 159, a cutter displacement cylinder 161, and a cutter 162.

[0096] The cutting seat 158 ​​is connected to the workbench 110, the third linear motion module 159 is connected to the cutting seat 158, and the cutter displacement cylinder 161 is connected to the third linear motion module 159, and the third linear motion module 159 is used to drive the cutter displacement cylinder 161 to move along the first preset direction or the second preset direction;

[0097] The cutter 162 is connected to the cutter displacement cylinder 161, and the cutter displacement cylinder 161 is used to drive the cutter 162 to move along the second preset direction or the first preset direction.

[0098] Through the above-mentioned structural setting, during use, the cutter displacement cylinder 161 can drive the cutter 162 to move, so that the cutter 162 is close to or away from the battery cell 10, and then the cutter 162 moves between the position of cutting the tape or moving out of the cutting position; and the third linear motion module 159 is used to drive the cutter displacement cylinder 161 and the cutter 162 to move along the extension direction of the corresponding side of the battery cell 10, so as to cut the tape on the corresponding side of the battery cell 10.

[0099] That is, when the tape cutting assembly 155 is used to cut the tape on the side of the battery cell 10 extending along the first preset direction, at this time, the third linear motion module 159 is used to drive the cutter displacement cylinder 161 and the cutter 162 along the first preset direction, and the cutter displacement cylinder 161 is used to drive the cutter 162 to move along the second preset direction; when the tape cutting assembly 155 is used to cut the tape on the side of the battery cell 10 extending along the second preset direction, at this time, the third linear motion module 159 is used to drive the cutter displacement cylinder 161 and the cutter 162 along the second preset direction, and the cutter displacement cylinder 161 is used to drive the cutter 162 to move along the first preset direction.

[0100] It should be noted that when configuring the cutting seat 158, a linear module can also be configured so that it can move relative to the workbench 110, and its movement direction can be along a second preset direction to adjust its distance relative to the battery cell transfer unit 130. In addition, on the basis that the cutting seat 158 ​​can move relative to the workbench 110, one of the tape cutting components 155 can also be connected to the cutting seat 158, so that it can move synchronously with it.

[0101] For further information, please refer to Figure 1-Figure 17 In this embodiment, when the battery cell removal unit 190 is configured, its function is to grab the core 20 at the unloading position and remove it. Therefore, the battery cell removal unit 190 includes a core clamping arm 191 and a core transfer belt 192;

[0102] The core clamping arm 191 and the core transfer belt 192 are both connected to the workbench 110, and the core clamping arm 191 is used to clamp the core 20 on the battery cell transfer unit 130 in the unloading position and transfer the core 20 to the core transfer belt 192; the core transfer belt 192 is used to move the received core 20 out of the workbench 110.

[0103] It should be noted that the core clamping arm 191 can adopt a mechanical arm structure, and its spatial freedom can be adjusted according to usage requirements. In addition, a sensor 193 and an image collector 194 are arranged at its clamping end. Its purpose is to sense the state of the core clamping arm 191 clamping the core 20 through the sensor 193, and to collect the image of the core 20 to be grasped or the core 20 grasped by the core clamping arm 191 through the image collector 194, and then the separated core 20 can be identified and sensed according to its sensing function and image acquisition function, thereby facilitating the inspection and identification of the core 20, so as to improve efficiency and realize automation.

[0104] For further information, please refer to Figure 1-Figure 17 On the basis of the above structure, taking the separation of the core 20 of the square aluminum shell battery 10 as an example, the battery 10 is a four-core 20 structure, and the battery 10 of the four-core 20 is divided into two groups, each group of battery 10 includes two stacked cores 20, thus, in order to improve the separation efficiency, therefore, for the four-core 20, the battery separation device 100 includes two battery transfer units 130, two battery separation units 150 and two battery transfer manipulators 170;

[0105] The two battery cell transfer units 130 share the same first linear motion module 131; the two battery cell separation units 150 are distributed on both sides of the first linear motion module 131 along the first preset direction; the two battery cell transfer manipulators 170 share the same third linear motion module 159;

[0106] Among them, the movement directions of the two battery cell transfer robots 170 are opposite, each battery cell transfer robot 170 corresponds to a battery cell transfer unit 130 and a battery cell separation unit 150, and each battery cell transfer robot 170 is used to grab the battery cell 10 on the corresponding battery cell transfer unit 130 and transfer it to the corresponding battery cell separation unit 150; and transfer the winding core 20 separated from the corresponding battery cell separation unit 150 to the corresponding battery cell transfer unit 130.

[0107] That is, the two battery cell transfer units 130 can place two battery cells 10 at the same time, and the two battery cell transfer robots 170 can grab the two battery cells 10 synchronously or in steps, and the two battery cell separation units 150 can separate the two battery cells 10 synchronously or in steps, and the two battery cell transfer robots 170 can grab the two winding cores 20 synchronously or in steps; and thus, through such a setting, when the two battery cell transfer units 130, the two battery cell separation units 150 and the two battery cell transfer robots 170 are running synchronously, the two battery cells 10 can be separated synchronously, thereby improving the separation efficiency of the battery cells 10.

[0108] Please refer to Figure 1-Figure 17 The following is an example of the cell separation device 100 separating the winding core 20 of the square aluminum shell cell 10, and the process includes:

[0109] The battery cells 10 of the four-roll core 20 are placed flat on two battery cell platforms 132, and the battery cell platforms 132 are in the loading position. The first battery cell positioning cylinder 134 of the first positioning assembly 133 drives the first positioning plate 135 to move and preliminarily position the battery cells 10;

[0110] The second linear motion module 172 of the cell transfer robot 170 drives the two gripper lifting cylinders 173 to move to the top of the cell platform 132 at the loading position; then, the two gripper lifting cylinders 173 operate synchronously, driving the corresponding gripper cylinders 174 and grippers 175 to move to the grasping position respectively;

[0111] The clamping cylinders 174 on the two clamping claw lifting cylinders 173 drive the corresponding clamping claws 175 to move, grabbing the battery cells 10 on the two battery cell platforms 132; then, the two clamping claw lifting cylinders 173 rise, and the second linear motion module 172 drives the two clamping claw lifting cylinders 173 to move to the top of the separation platform 153 respectively;

[0112] The two battery cell separation units 150 can be symmetrically arranged relative to the first linear motion module 131, and the two clamping claw lifting cylinders 173 operate synchronously to drive the corresponding clamping claw cylinders 174 and the clamping claws 175 to move to the position of releasing the battery cell 10, and then the clamping claw cylinders 174 on the two clamping claw lifting cylinders 173 drive the corresponding clamping claws 175 to move, and release the two grasped battery cells 10 to the corresponding separation platform 153 respectively;

[0113] The working steps of the two battery cell separation units 150 are the same, so taking the working steps of one of the battery cell separation units 150 as an example, the second positioning component 154 on the battery cell separation unit 150 is actuated to fix the battery cell 10;

[0114] The lifting motion module 152 drives the separation table 153 to move to an appropriate height. Then, taking the device configured with three tape cutting assemblies 155 as an example, the cutter displacement cylinder 161 of the tape cutting assembly 155 located on both sides of the battery cell 10 drives the cutter 162 to extend toward the battery cell 10, and then the third linear motion module 159 drives the cutter displacement cylinder 161 and the cutter 162 to move and cut the paired tapes on both sides; and the cutter displacement cylinder 161 of the tape cutting assembly 155 located at the head of the winding core 20 drives the cutter 162 to extend toward the battery cell 10, and then the third linear motion module 159 drives the cutter displacement cylinder 161 and the cutter 162 to move and cut off the tapes wound on the head of the winding core 20;

[0115] The lifting motion module 152 drives the separation platform 153 to rise, and the whole rises by one battery cell 10 position, and the gripper lifting cylinder 173 on the battery cell transfer robot 170 descends, and the gripper cylinder 174 clamps and extends the gripper 175 to the middle of the two layers of winding cores 20, and then the gripper lifting cylinder 173 rises, and the upper layer of winding core 20 is taken away to separate the winding core 20;

[0116] The second linear motion module 172 operates, driving the two clamping claw lifting cylinders 173 to move to the top of the corresponding battery cell platform 132, the clamping claw lifting cylinders 173 descend, and the clamping claw cylinders 174 release to place the upper winding core 20 on the battery cell platform 132;

[0117] The first linear motion module 131 operates to move the two battery cell platforms 132 from the loading position to the unloading position, and the core clamping arm 191 transfers the core 20 to the core transfer belt 192 through the material taking claw 175, and then transfers it to the next station through the core transfer belt 192;

[0118] Then, the first linear motion module 131 operates to move the two battery cell platforms 132 from the unloading position to the loading position, and at the same time, the lifting motion module 152 drives the separation platform 153 to descend, and the battery cell transfer manipulator 170 moves to the top of the separation platform 153; the clamping claw lifting cylinder 173 descends, and the clamping claw cylinder 174 clamps and grabs the lower layer core 20, and then the clamping claw lifting cylinder 173 rises to take the lower layer core 20 away to separate the core 20;

[0119] The second linear motion module 172 operates, driving the two clamping claw lifting cylinders 173 to move to the top of the corresponding battery cell platform 132, the clamping claw lifting cylinders 173 descend, and the clamping claw cylinders 174 release to place the lower winding core 20 on the battery cell platform 132;

[0120] The first linear motion module 131 operates to move the two battery cell platforms 132 from the loading position to the unloading position, and the core clamping arm 191 transfers the core 20 to the core transfer belt 192 through the material taking claw 175, and then transfers it to the next station through the core transfer belt 192;

[0121] Thus, the separation of one battery cell 10 is completed;

[0122] For the batch separation of the battery cells 10 , the above steps can be repeated.

[0123] Please refer to Figure 1-Figure 17 Based on the above-mentioned cell separation device 100, this embodiment further provides a cell 10 separation line, which includes a loading unit, a unloading unit and the above-mentioned cell separation device 100; the loading unit is used to transfer the cell 10 to the cell transfer unit 130, and the unloading unit is used to receive the core 20 transferred and output by the core 20. By adopting the above-mentioned cell separation device 100, the cell 10 separation line can improve the separation efficiency of the cell 10, which is conducive to realizing the fully automated separation of the cell 10, and can also prevent the cell 10 from being damaged during the separation process, thereby improving the safety and consistency of separation and reducing the separation cost.
