[0062] Please refer to Figures 1-9 The present embodiment provides a kind of electric core separation device 100, electric core separation device 100 includes workbench 110, electric core transfer unit 130, electric core separation unit 150, electric core transfer manipulator 170 and electric core removal unit 190;

[0063] Electric core transfer unit 130 is movably connected with workbench 110 along first preset direction, and at least has feeding position (such as Figure 9 Position shown in mark A) and discharging position (such as Figure 9 Position shown in mark B);

[0064] Electric core transfer manipulator 170 is connected with workbench 110, and electric core transfer manipulator 170 is used to grab the electric core 10 on electric core transfer unit 130 in feeding position, and it is transferred to electric core separation unit 150, and is used to after electric core 10 is separated into roll core 20 in electric core separation unit 150, roll core 20 is transferred to the electric core transfer unit 130 in feeding position;

[0065] Electric core removal unit 190 is used to grab and remove roll core 20 on electric core transfer unit 130 in discharging position.

[0066] Please refer to Figures 1-9 The working principle of the electric core separation device 100 is:

[0067] The electric core separation device 100 includes workbench 110, electric core transfer unit 130, electric core separation unit 150, electric core transfer manipulator 170 and electric core removal unit 190;Wherein, electric core transfer unit 130 is used to bear the electric core 10 to be separated and the roll core 20 after separation, to facilitate electric core transfer manipulator 170 and electric core removal unit 190 grab, so as to improve efficiency;And electric core separation unit 150 is used to separate electric core 10;And electric core removal unit 190 is used to grab roll core 20 after separation, and remove it;

[0068] Specifically, when the battery cell transfer unit 130 is configured, it is movably connected with the workbench 110 along a first preset direction, and at least has a loading position and an unloading position. Thus, when the battery cell transfer unit 130 is at the loading position, it can receive the battery cell 10 to be separated, and when the battery cell transfer unit 130 is at the unloading position, it is convenient for the battery cell removal unit 190 to grasp the roll core 20.

[0069] The battery cell transfer robot 170 is connected with the workbench 110, and is used to grasp the battery cell 10 on the battery cell transfer unit 130 at the loading position, and transfer the battery cell 10 to the battery cell separation unit 150, and is used to transfer the roll core 20 separated from the battery cell 10 by the battery cell separation unit 150 to the battery cell transfer unit 130 at the loading position. Thus, through the arrangement of the battery cell transfer robot 170, the battery cell transfer robot 170 can move between the battery cell transfer unit 130 at the loading position and the battery cell separation unit 150, so as to grasp and transfer the battery cell 10 to be separated, and grasp and transfer the roll core 20 separated from the battery cell 10, thereby improving the transfer efficiency of the battery cell 10 and the roll core 20, and improving the separation efficiency of the battery cell 10.

[0070] The battery cell removal unit 190 is used to grasp and remove the roll core 20 on the battery cell transfer unit 130 at the unloading position.

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

[0072] It should be noted that in the embodiment, the first preset direction, the second preset direction and the third preset direction are perpendicular to each other, and specifically, the first preset direction, the second preset direction and the third preset direction correspond to the arrow X, the arrow Y and the arrow Z in the drawings.

[0073] Further, please refer to Figures 1-9 In the embodiment, when the battery cell transfer unit 130 is configured, as known from the above, it is used to carry the battery cell 10 to be separated and the roll core 20 after separation, so as to facilitate the battery cell transfer robot 170 and the battery cell removal unit 190 to grasp, thereby improving the efficiency. Thus, in order to enable the battery cell transfer unit 130 to change positions between the loading position and the unloading position, and to play a positioning role on the battery cell 10 and the roll core 20, the battery cell transfer unit 130 comprises a first linear motion module 131, a battery cell platform 132 and a first positioning assembly 133.

[0074] The first linear motion module 131 is connected with the workbench 110, the battery cell platform 132 is connected with the first linear motion module 131, and the first linear motion module 131 is connected with the battery cell platform 132. The first linear motion module 131 is used to drive the battery cell platform 132 to move along a first preset direction, so as to change positions between a feeding position and a discharging position.

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

[0076] Therefore, during use, the first linear motion module 131 can drive the battery cell platform 132 to move along the first preset direction relative to the workbench 110, so as to change positions between the feeding position and the discharging position. It should be noted that the feeding position and the discharging position can be two interval position points in the stroke of the first linear motion module 131 along the first preset direction, or can be two ends of the stroke.

[0077] During the movement of the first linear motion module 131 driving the battery cell platform 132, or when the first linear motion module 131 is at the feeding position or the discharging position, the first positioning assembly 133 can position or clamp the battery cell 10 or the roll core 20 placed on the battery cell platform 132. The purpose is to improve the stability of the battery cell 10 or the roll core 20 on the battery cell platform 132.

[0078] Therefore, when the first linear motion module 131 is configured, a linear motion mechanism in the prior art can be used, such as a cylinder, a hydraulic cylinder, a linear motor, a screw and slider module, or other types of linear motion modules.

[0079] When the first positioning assembly 133 is configured, the purpose is to position the battery cell 10 or the roll core 20, or to clamp the battery cell 10 or the roll core 20. Therefore, the first positioning assembly 133 includes a first battery cell positioning cylinder 134 and a first positioning plate 135. The first battery cell positioning cylinder 134 is connected with the battery cell platform 132, and the first positioning plate 135 is connected with 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 a second preset direction, so as to abut against the battery cell 10 or the roll core 20 on the battery cell platform 132. The first preset direction is perpendicular to the second preset direction.

[0080] Through such a setting mode, the first positioning plate 135 can be driven to move by the first positioning cylinder, and then move relative to the battery platform 132, so as to abut against the battery 10 or the roll core 20 placed on the battery platform 132, so as to position the battery 10 or the roll core 20; on this basis, the number of the first positioning assembly 133 can be increased, that is, one first positioning plate 135 is distributed on each side of the battery platform 132, so that one of the two first positioning plates 135 can be driven to move by the two first positioning cylinders, so as to clamp the battery 10 or the roll core 20 placed on the battery platform 132.

[0081] Further, please refer to Figures 1-11 In the embodiment, when the battery transfer manipulator 170 is configured, the battery transfer manipulator 170 is used to grasp the battery 10 or the roll core 20 and transfer the position of the battery 10 or the roll core 20, specifically, the battery 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 with the workbench 110, the second linear motion module 172 is connected with the movable frame 171, and the gripper lifting cylinder 173 is connected with the second linear motion module 172; the two gripper cylinders 174 are both connected with the gripper lifting cylinder 173, and the gripper lifting cylinder 173 is used to drive the two gripper cylinders 174 to move along a third preset direction; the two grippers 175 are respectively connected with the two gripper cylinders 174, and the two gripper cylinders 174 are respectively used to drive the corresponding gripper 175 to move along a first preset direction or a second preset direction, so as to clamp or release the battery 10 or the roll core 20.

[0083] The second linear motion module 172 is used to drive the gripper lifting cylinder 173 to move along a second preset direction, so as to change the position between the upper side of the battery platform 132 in the feeding position and the upper side of the battery separation unit 150.

[0084] Through the structural arrangement manner, in the embodiment, the second linear motion module 172 can drive the clamp jaw lifting cylinder 173 to move in the second preset direction, and the clamp jaw lifting cylinder 173 can change positions between the position above the battery cell platform 132 in the feeding position and the position above the battery cell separating unit 150 during movement in the second preset direction. In this way, the two clamp jaw cylinders 174 and the two clamp jaws 175 that grasp the battery cell 10 or the roll core 20 can move relative to the battery cell platform 132 and the battery cell separating unit 150. Then, when the two clamp jaw cylinders 174 and the two clamp jaws 175 move to the position above the battery cell platform 132, the clamp jaw lifting cylinder 173 can drive the two clamp jaw cylinders 174 to move in the third direction, so that the clamp jaw lifting cylinder 173 can move downward to grasp the battery cell 10 on the battery cell platform 132. When the two clamp jaw cylinders 174 and the two clamp jaws 175 are above the battery cell separating unit 150, the two clamp jaw cylinders 174 and the two clamp jaws 175 can release the grasped battery cell 10 and grasp the battery cell 10 after separation. In addition, when the two clamp jaw cylinders 174 and the two clamp jaws 175 grasp the roll core 20, the two clamp jaw cylinders 174 and the two clamp jaws 175 can release the roll core 20 to the battery cell platform 132.

[0085] Under the action of the second linear module and the clamp jaw lifting cylinder 173, the two clamp jaws 175 that perform the grasping action can move in the second preset direction and the first preset direction with the two clamp jaw cylinders 174, so that the two clamp jaws 175 can be adjusted to the position above the battery cell platform 132 or the position above the battery cell separating unit 150. On this basis, the two clamp jaw cylinders 174 can drive the corresponding clamp jaws 175 to move, so that the two clamp jaws 175 can move close to each other to perform the grasping action of the battery cell 10 or the roll core 20. When the two clamp jaws 175 move away from each other, the two clamp jaws 175 can release the grasped battery cell 10 or roll core 20. It should be noted that the position above the battery cell platform 132 refers to the position above the battery cell platform 132 in the feeding position.

[0086] When the second linear motion module 172 is configured, a linear motion mechanism in the prior art can be used, such as a cylinder, a hydraulic cylinder, a linear motor, a screw and nut module, or other types of linear motion modules.

[0087] Further, please refer to Figures 1-15 In the embodiment, when the battery cell separating unit 150 is configured, the function of the battery cell separating unit 150 is to separate the battery cell 10 into the roll core 20. In the specific operation, the separating action is that the cutter 162 cuts the adhesive paper on the outside of the battery cell 10, so that the connection of the adhesive paper to the stacked roll core 20 is eliminated. Therefore, when the battery cell separating unit 150 is configured, the battery cell separating unit 150 includes a separating seat 151, a lifting motion module 152, a separating table 153, a second positioning assembly 154, and at least one adhesive paper cutting assembly 155.

[0088] The separation seat 151 is connected with the workbench 110, the lifting movement module 152 is connected with the separation seat 151, and the separation table 153 is connected with the lifting movement module 152. The lifting movement module 152 is used to drive the separation table 153 to move along a third preset direction. The second positioning assembly 154 is connected with the separation table 153, and the second positioning assembly 154 is used to position or resist the battery cell 10 or the roll core 20 on the separation table 153. The adhesive paper cutting assembly 155 is connected with the workbench 110, and the adhesive paper cutting assembly 155 is used to cut the adhesive paper outside the battery cell 10. The first preset direction, the second preset direction and the third preset direction are perpendicular to each other.

[0089] Therefore, through the above structure, the height of the separation table 153 can be adjusted by the movement of the lifting movement module 152 in the third preset direction, so that the battery cell 10 is at a suitable height for receiving the battery cell 10 or at a height convenient for the transfer robot 170 to grab. The battery cell 10 placed on the separation table 153 is also at a height for the adhesive paper cutting assembly 155 to cut the adhesive paper.

[0090] It should be noted that the present embodiment is configured with three adhesive paper cutting assemblies 155, which are the first adhesive paper cutting assembly 163, the second adhesive paper cutting assembly 164 and the third adhesive paper cutting assembly 165. The first adhesive paper cutting assembly 163 and the second adhesive paper cutting assembly 164 are located on both sides of the battery cell 10, and the third adhesive paper cutting assembly 165 is located at the head of the battery cell 10. The working principles of the first adhesive paper cutting assembly 163, the second adhesive paper cutting assembly 164 and the third adhesive paper cutting assembly 165 are the same, so the working process of one of the adhesive paper cutting assemblies 155 is taken as an example for description.

[0091] When configuring the lifting movement module 152, a linear motion mechanism in the prior art can be used, such as a cylinder, a hydraulic cylinder, a linear motor, a screw block module or other types of linear motion modules.

[0092] In the configuration of the second positioning assembly 154, the function is to position or clamp the battery cell 10 or the roll cell 20 on the separation table 153, and the purpose is to avoid the battery cell 10 from moving relative to the separation table 153 when the battery cell 10 is cut by the adhesive paper cutting assembly 155 or when the battery cell 10 is separated by the battery cell transfer robot 170. Therefore, the second positioning assembly 154 is configured, and the second positioning assembly 154 includes two second battery cell positioning cylinders 156 and two second positioning plates 157. The two second battery cell positioning cylinders 156 are connected with the separation table 153, and the two second positioning plates 157 are connected with the two second battery cell positioning cylinders 156, respectively. 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 roll cell 20 on the separation table 153. The two second positioning plates 157 are oppositely arranged along the first preset direction or the second preset direction.

[0093] That is, the battery cell 10 can be clamped by such a setting mode. It should be noted that when the battery cell 10 or the roll cell 20 is clamped by the two second positioning plates 157, the function is to keep the position of the battery cell 10 or the roll cell 20. In this process, in order to avoid the interference between the second positioning plate 157 and the adhesive paper cutting assembly 155 or the battery cell transfer robot 170, for example, the second positioning plate 157 clamps the position of the battery cell 10 outside the lower roll cell 20 of the battery cell 10 with two layers of roll cells 20. When the adhesive paper cutting assembly 155 cuts the adhesive paper, the area between the two layers of roll cells 20 of the battery cell 10 is cut. When the battery cell transfer robot 170 transfers the roll cell 20, the upper roll cell 20 is transferred first, and then the lower roll cell 20 is transferred.

[0094] In the configuration of the adhesive paper cutting assembly 155, in order to facilitate the separation of the battery cell 10, for example, each adhesive paper cutting assembly 155 is used to cut the adhesive paper on one side of the battery cell 10. Then, the adhesive paper cutting assembly 155 is set according to the adhesive paper on the outside of the battery cell 10. In this embodiment, three groups of adhesive paper cutting assemblies 155 are configured, which are distributed on three different sides of the battery cell 10. Each adhesive paper cutting assembly 155 cuts the adhesive paper on one side of the battery cell 10.

[0095] The structure of a single adhesive paper cutting assembly 155 will be described below. Specifically, the adhesive paper 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 with the workbench 110, the third linear motion module 159 is connected with the cutting seat 158, and the cutting knife displacement cylinder 161 is connected with the third linear motion module 159, and the third linear motion module 159 is used for driving the cutting knife displacement cylinder 161 to move along the first preset direction or the second preset direction;

[0097] The cutting knife 162 is connected with the cutting knife displacement cylinder 161, and the cutting knife displacement cylinder 161 is used for driving the cutting knife 162 to move along the second preset direction or the first preset direction.

[0098] Through the above structural arrangement mode, in the process of use, the cutting knife 162 is driven to move by the cutting knife displacement cylinder 161, so that the cutting knife 162 approaches or moves away from the battery cell 10, and then the cutting knife 162 moves between the position of cutting the adhesive tape and moving out of the cutting position; and the third linear motion module 159 is used for driving the cutting knife displacement cylinder 161 and the cutting knife 162 to move along the extension direction of the corresponding side surface of the battery cell 10, so as to cut the adhesive tape of the corresponding side surface of the battery cell 10.

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

[0100] It should be noted that when the cutting seat 158 is configured, a linear module can also be configured, which can move relative to the workbench 110, and the movement direction can be moving along the second preset direction to adjust the distance relative to the battery cell transfer unit 130, and on the basis that the cutting seat 158 can move relative to the workbench 110, one of the adhesive tape cutting assemblies 155 can also be connected with the cutting seat 158, so as to move synchronously.

[0101] Further, please refer to Figures 1-17 In the embodiment, when the battery cell moving-out unit 190 is configured, its role is to grasp the roll core 20 on the discharging position and move it out, so that the battery cell moving-out unit 190 includes a roll core clamping arm 191 and a roll core transfer belt 192;

[0102] The winding core clamping arm 191 and the winding core transfer belt 192 are connected with the workbench 110, and the winding core clamping arm 191 is used for clamping the winding core 20 on the battery cell transfer unit 130 in the discharging position and transferring the winding core 20 to the winding core transfer belt 192; the winding core transfer belt 192 is used for moving the received winding core 20 out of the workbench 110.

[0103] It should be noted that the winding core clamping arm 191 can adopt a mechanical arm structure, the spatial degrees of freedom of which can be adjusted according to the use requirements, and a sensor 193 and an image collector 194 are arranged at the clamping end of the winding core clamping arm 191, the purpose of which is to sense the state of the winding core 20 clamped by the winding core clamping arm 191 through the sensor 193, and to collect the image of the winding core 20 to be grabbed or the winding core 20 grabbed by the winding core clamping arm 191 through the image collector 194, so as to identify and sense the separated winding core 20 according to the sensing function and the image collection function, thereby facilitating the inspection and identification of the winding core 20, so as to improve the efficiency and realize automation.

[0104] Further, please refer to Figures 1-17 On the basis of the above structure, taking the winding core 20 separation work of the square aluminum shell type battery cell 10 as an example, the battery cell 10 is a four-winding core 20 structure, and the four-winding core 20 battery cell 10 is divided into two groups, and each group of battery cell 10 includes two stacked winding cores 20, so as to improve the separation efficiency, therefore, for the four-winding core 20, the battery cell separation device 100 includes two battery cell transfer units 130, two battery cell separation units 150 and two battery cell 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 the two sides of the first linear motion module 131 along the first preset direction; and 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 manipulators 170 are opposite, each battery cell transfer manipulator 170 corresponds to one battery cell transfer unit 130 and one battery cell separation unit 150, and each battery cell transfer manipulator 170 is used for grabbing the battery cell 10 on the corresponding battery cell transfer unit 130 and transferring it to the corresponding battery cell separation unit 150; and transferring the separated winding core 20 on the corresponding battery cell separation unit 150 to the corresponding battery cell transfer unit 130.

[0107] That is, the two cell transfer units 130 can place two cells 10 at the same time, the two cell transfer robots 170 can synchronously or step by step perform the grabbing action of the two cells 10, the two cell separation units 150 can synchronously or step by step perform the separation action of the two cells 10, and the two cell transfer robots 170 can synchronously or step by step perform the grabbing action of the two winding cores 20; further, through such a setting mode, in the case of synchronous operation of the two cell transfer units 130, the two cell separation units 150 and the two cell transfer robots 170, the two cells 10 can be separated synchronously, thereby improving the separation efficiency of the cells 10.

[0108] Please refer to Figures 1-17 , the following will take the winding core 20 of the square aluminum shell type cell 10 separated by the cell separation device 100 as an example for description, and the process includes:

[0109] The four winding cores 20 of the cell 10 are placed flat on the two cell platforms 132, the cell platform 132 is in the feeding position, and the first cell positioning cylinder 134 of the first positioning assembly 133 drives the first positioning plate 135 to move to preliminarily position the cell 10;

[0110] The second linear motion module 172 of the cell transfer robot 170 drives the two jaw lifting cylinders 173 to move to the upper position of the cell platform 132; then, the two jaw lifting cylinders 173 are synchronously operated to drive the corresponding jaw cylinder 174 and the jaw 175 to move to the grabbing position;

[0111] The jaw cylinder 174 on the two jaw lifting cylinders 173 drives the corresponding jaw 175 to act to grab the cell 10 of the two cell platforms 132; then, the two jaw lifting cylinders 173 are raised, and the second linear motion module 172 drives the two jaw lifting cylinders 173 to move to the upper position of the separation table 153;

[0112] The two cell separation units 150 can be symmetrically arranged relative to the first linear motion module 131, the two jaw lifting cylinders 173 are synchronously operated to drive the corresponding jaw cylinder 174 and the jaw 175 to move to the position of releasing the cell 10, then the jaw cylinder 174 on the two jaw lifting cylinders 173 drives the corresponding jaw 175 to act to release the grabbed two cells 10 to the corresponding separation table 153;

[0113] The working steps of the two cell separation units 150 are the same, therefore, taking the working steps of one of the cell separation units 150 as an example, the second positioning assembly 154 on the cell separation unit 150 acts to fix the cell 10;

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

The jaw lifting cylinder 173 on the battery cell transfer manipulator 170 descends, the jaw cylinder 174 clamps the jaw 175 to extend to the middle of the two winding cores 20, and then the jaw lifting cylinder 173 rises to take the upper winding core 20 away to realize the separation of the winding core 20;

[0116] The second linear motion module 172 operates to drive the two jaw lifting cylinders 173 to move to the upper side of the corresponding battery cell platform 132. The jaw lifting cylinder 173 descends, and the jaw cylinder 174 releases 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 feeding position to the discharging position. The winding core clamping arm 191 transfers the winding core 20 to the winding core transfer belt 192 through the taking material jaw 175, and then transfers to the next station through the winding core transfer belt 192;

[0118] Then, the first linear motion module 131 operates to move the two battery cell platforms 132 from the discharging position to the feeding position, and the lifting movement module 152 drives the separation table 153 to descend. The battery cell transfer manipulator 170 moves to the upper side of the separation table 153. The jaw lifting cylinder 173 descends, and the jaw cylinder 174 clamps to grab the lower winding core 20. Then, the jaw lifting cylinder 173 rises to take the lower winding core 20 away to realize the separation of the winding core 20;

[0119] The second linear motion module 172 operates to drive the two jaw lifting cylinders 173 to move to the upper side of the corresponding battery cell platform 132. The jaw lifting cylinder 173 descends, and the jaw cylinder 174 releases 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 cell platforms 132 from the feeding position to the discharging position, the roll core clamping arm 191 transfers the roll core 20 to the roll core transfer belt 192 through the material taking clamping jaw 175, and the roll core 20 is transferred to the next work station through the roll core transfer belt 192;

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

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