Exemplarily, a limiting member can also be provided on the support tabletop to limit the core 70 to be separated to prevent displacement when the tabs of the core 70 to be separated are cut.

[0053] The cutting component is used to cut the tabs of the core 70 to be separated, so that the electrode plates and the separator of the core 70 to be separated are unfolded, and then the tab group to be separated and the separator group to be separated are obtained.

[0054] The grasping component 50 is located above the core 70 to be separated. The grasping component 50 can move up and down, and the grasping component 50 can also perform opening and closing operations. The tab separating mechanism 30 can be used to drive the tab group to be separated to move, so as to realize the separation of the tab group to be separated. The separator separating mechanism 40 can be fixedly arranged on the cutting component by screwing, clamping or welding, etc. The separator separating mechanism 40 can be used to drive the separator group to be separated to rotate, so as to realize the winding of the separator group to be separated.

[0055] The grasping component 50 is used to grasp the tab group to be separated and place the tab group to be separated on the tab separating mechanism 30.

The grasping component 50 is also used to grasp the separator group to be separated and place the separator group to be separated on the separator separating mechanism 40. Then, the separator separating mechanism 40 winds the separator group to be separated, realizing the winding operation of the separator separation of the core 70 to be separated.

[0056] In the above embodiments, the cutting assembly is disposed on the support assembly 10, and the grasping assembly 50 is disposed on the support assembly 10. The support assembly 10 is used to support the core 70 to be separated; the cutting assembly is used to cut the tabs of the core 70 to be separated to obtain the tab group to be separated and the separator group to be separated; the grasping assembly 50 is used to grasp the tab group to be separated to the tab separating mechanism 30 and to grasp the separator group to be separated to the separator separating mechanism 40; the tab separating mechanism 30 is used to separate the tab group to be separated; the separator separating mechanism 40 is used to wind up the separator group to be separated, so as to realize the tab separation operation and the separator separation operation of the core 70 to be separated. In this application, by disposing the cutting assembly on the support assembly 10, the tabs of the core 70 to be separated are accurately cut by the cutting assembly, so that the tabs and the separator of the core 70 to be separated can be unfolded; by disposing the grasping assembly 50 on the support assembly 10, the tab group to be separated is grasped by the grasping assembly 50 and placed on the tab separating mechanism 30, and then the tab separating mechanism 30 can timely separate the tab group to be separated; by grasping the separator group to be separated by the grasping assembly 50 and placing the separator group to be separated on the separator separating mechanism 40, the separator separating mechanism 40 can timely wind up the separator group to be separated, realizing the rapid and accurate separation of the electrode tabs and the separator, simplifying the separation operation, preventing the direct contact between the positive and negative tabs during the separation process, and improving the efficiency and safety of the core separation.

[0057] In one embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the cutting assembly includes a moving and adjusting assembly 210 and a cutting tool group 220; the moving and adjusting assembly 210 is movably connected to the support assembly 10, and the cutting tool group 220 is disposed on the moving and adjusting assembly 210; the moving and adjusting assembly 210 is used to drive the cutting tool group 220 to move along a first direction to adjust the cutting position of the tabs of the core 70 to be separated; the moving and adjusting assembly 210 is further used to drive the cutting tool group 220 to move along a second direction to cut the tabs of the core 70 to be separated.

[0058] Wherein, the moving and adjusting assembly 210 can be movably disposed on the support assembly 10 through a connecting rod, and thus the moving and adjusting assembly 210 can be used to drive the cutting tool group 220 to move along the first direction, and the moving and adjusting assembly 210 can also be used to drive the cutting tool group 220 to move along the second direction. Exemplarily, the first direction is the horizontal direction and the second direction is the vertical direction, that is, the first direction is perpendicular to the second direction.

[0059] The cutting tool group 220 can be arranged on the bottom surface of the moving and adjusting component 210, so that the cutting tool group 220 is located above the core 70 to be separated. In one example, the cutting tool group 220 includes an arc-shaped knife 222 and / or a square knife 224. For example, the cutting tool group 220 includes a first arc-shaped knife 222, a second arc-shaped knife 222, a first square knife 224 and a second square knife 224. The first arc-shaped knife 222 and the first square knife 224 are arranged at the first end of the moving and adjusting component 210, and the second arc-shaped knife 222 and the second square knife 224 are arranged at the second end of the moving and adjusting group. When the core 70 to be separated is a square core, the core 70 to be separated has a first tab cutting area and a second tab cutting area; the first square knife 224 can be controlled to cut the first tab cutting area of the core 70 to be separated, and the second square knife 224 can be controlled to cut the second tab cutting area of the core 70 to be separated, so that the electrode tab and the separator of the core 70 to be separated are unfolded, and the tab group to be separated and the separator group to be separated are obtained. Similarly, when the core 70 to be separated is an arc-shaped core, the first arc-shaped knife 222 can be controlled to cut the first tab cutting area of the core 70 to be separated, and the second arc-shaped knife 222 can be controlled to cut the second tab cutting area of the core 70 to be separated, so that the electrode tab and the separator of the core 70 to be separated are unfolded, and the tab group to be separated and the separator group to be separated are obtained. By setting cutting tools of different shapes, more types of cores can be adapted, and the versatility of the core separation device is improved.

[0060] Exemplarily, the moving and adjusting component 210 can include a first electric control module and a second electric control module. The first electric control module is connected to the cutting tool group 220, and the first electric control module is used to control the cutting tool group 220 to move up and down along the second direction. The second electric control module is used to control the cutting tool group 220 to move horizontally along the first direction.

[0061] According to the size of the core 70 to be separated, the moving and adjusting component 210 is adjusted so that the moving and adjusting component 210 drives the cutting tool group 220 to move along the first direction until the cutting direction of the cutting tool group 220 is aligned with the tab cutting position of the core 70 to be separated. The moving and adjusting component 210 is further adjusted so that the moving and adjusting component 210 drives the cutting tool group 220 to move along the second direction, realizing the tab cutting of the core 70 to be separated, so that the electrode tab and the separator of the core 70 to be separated are unfolded, so as to grasp and separate the tab group to be separated and the separator group to be separated, realizing accurate control of the length of the tab cutting of the core 70 to be separated, so that the tab unfolding operation can be carried out and potential hazards such as short circuit and fire will not occur, and the safety of the battery disassembly operation is improved.

[0062] In one embodiment, as Figure 4 and Figure 5As shown, the moving adjustment assembly 210 includes a first support rod 212, a sliding rod group 216, and a fastening assembly 218; the first support rod 212 is arranged on the support assembly 10 along a first direction, the sliding rod group 216 is sleeved on the first support rod 212, and the cutter group 220 is arranged on the sliding rod group 216; the sliding rod group 216 is used to move along the first support rod 212 to drive the cutter group 220 to move along the first direction, so that the cutting direction of the cutter group 220 is aligned with the tab cutting position of the core 70 to be separated; the fastening assembly 218 is used to fix the sliding rod group 216 after moving adjustment on the support assembly 10.

[0063] Among them, the first support rod 212 is located above the core 70 to be separated placed on the support assembly 10, and the first support rod 212 can be in a long rectangular structure. The first support rod 212 can be fixedly arranged on the support assembly 10 by means of screwing, welding or clamping. The first support rod 212 is horizontally arranged on the support assembly 10 along the first direction, and then the sliding rod group 216 can move horizontally along the first support rod 212.

[0064] The sliding rod group 216 may include a first sliding rod and a second sliding rod, and the first sliding rod and the second sliding rod can be in a long rectangular structure. The first sliding rod is provided with a first through hole, the second sliding rod is provided with a second through hole, the first sliding rod is sleeved on the first end of the first support rod 212 through the first through hole, and the first sliding rod can move along the first direction; the second sliding rod is sleeved on the second end of the first support rod 212 through the second through hole, and the second sliding rod can move along the first direction.

[0065] The fastening assembly 218 is used to lock the sliding rod group 216 after moving adjustment to prevent the cutter group 220 from having a horizontal displacement when cutting the tabs of the core 70 to be separated. The fastening assembly 218 may include at least one first fastener and at least one second fastener. The first fastener may include a first bolt column and a first bolt head; the second fastener may include a second bolt column and a second bolt head. The first sliding rod is further provided with at least one third through hole, the second sliding rod is further provided with at least one fourth through hole, each first fastener is arranged corresponding to each third through hole, and each second fastener is arranged corresponding to each fourth through hole.

[0066] Exemplarily, a first arc-shaped knife 222 and a first square knife 224 are disposed on the bottom surface of the first support rod 212, and a second arc-shaped knife 222 and a second square knife 224 are disposed on the bottom surface of the second support rod 530. When the square-shaped core 70 to be separated is placed on the support assembly 10, according to the size of the core 70 to be separated, the corresponding first bolt cap and second bolt cap are adjusted to be loosened, and the first sliding rod and the second sliding rod are respectively controlled to move based on the first support rod 212. Further, the first sliding rod drives the first square knife 224 to move along the first direction until the cutting direction of the first square knife 224 aligns with the corresponding tab cutting position of the core 70 to be separated. The first bolt cap is locked on the corresponding first bolt column to fix the first sliding rod at the corresponding position on the first support rod 212, thereby fixing the first square knife 224 in the first direction. The second sliding rod drives the second square knife 224 to move along the first direction until the cutting direction of the second square knife 224 aligns with the corresponding tab cutting position of the core 70 to be separated. The second bolt cap is locked on the corresponding second bolt column to fix the second sliding rod at the corresponding position on the first support rod 212, thereby fixing the second square knife 224 in the first direction. Thus, by controlling the first square knife 224 and the second square knife 224 to move along the second direction, the tab cutting of the core 70 to be separated is realized, so that the electrode tab and the separator of the core 70 to be separated are unfolded, so as to grab and separate the to-be-separated tab group and the to-be-separated separator group, and accurately control the length of the tab cutting of the core 70 to be separated, so that the tab unfolding operation can be performed without potential hazards such as short circuit and fire, and the safety of the battery disassembly operation is improved.

[0067] In one embodiment, a scale is disposed on at least one side surface of the first support rod 212 along the first direction.

[0068] For example, the first support rod 212 has a top surface, and a scale is disposed on the top surface of the first support rod 212, and the scale is arranged along the first direction. According to the size of the core 70 to be separated and the scale on the first support rod 212, the sliding rod group 216 is controlled to move based on the first support rod 212, so that the cutting direction of the cutting knife group 220 aligns with the corresponding tab cutting position of the core 70 to be separated, realizing accurate positioning of the cutting position of the core 70 to be separated. Thus, it is easy to accurately control the position of the tab cutting of the core 70 to be separated, and the length of the tab cutting of the core 70 to be separated can be accurately controlled, so that the electrode tab and the separator can be unfolded without potential hazards such as short circuit and fire, and the safety of the battery disassembly operation is improved.

[0069] In one embodiment, as Figure 2 and Figure 4As shown, the diaphragm separation mechanism 40 includes a first roller 410 and a second roller 420; the diaphragm group to be separated includes a first-layer diaphragm and a second-layer diaphragm; the first roller 410 and the second roller 420 are arranged on the sliding rod group 216; the first roller 410 is used for winding the first-layer diaphragm; the second roller 420 is used for winding the second-layer diaphragm.

[0070] Among them, the first-layer diaphragm and the second-layer diaphragm are used to isolate the positive electrode plate and the negative electrode plate, avoiding direct contact between the positive electrode plate and the negative electrode plate, thereby avoiding short circuit and out-of-control chemical reactions inside the battery. The first roller 410 is used for winding the first-layer diaphragm, and the second roller 420 is used for winding the second-layer diaphragm. For example, the first roller 410 and the second roller 420 can be arranged on the first sliding rod, and the first roller 410 and the second roller 420 move along with the movement of the first sliding rod. Another example is that the first roller 410 and the second roller 420 can be arranged on the second sliding rod, and the first roller 410 and the second roller 420 move along with the movement of the second sliding rod.
