[0002] With the development of new energy technologies, the demand for batteries has surged. However, due to their short service life, the number of discarded batteries has also increased dramatically. Therefore, to reduce production costs and alleviate the environmental pollution caused by discarded batteries, it is necessary to separate and recycle the positive and negative electrode materials, positive and negative current collectors, and battery casings contained in discarded batteries.

[0045] The beneficial effects of this application are:

[0046] By setting up a cutting and loading mechanism that can load the positive electrode sheet to a fixed position close to the opening and can cut the positive electrode sheet at the fixed position, and a second clamping assembly and a third clamping assembly that can clamp and transport the positive electrode sheet from the fixed position to the cavity, the cutting and loading mechanism, the second clamping assembly and the third clamping assembly cooperate to automatically cut the positive electrode sheet into electrode segments and load them to the second clamping assembly and the third clamping assembly, so that the second clamping assembly and the third clamping assembly can apply a pulse current to the electrode segment, thereby separating the positive electrode material included in the electrode segment from the positive collector segment. In other words, by setting up a cutting and loading mechanism and a pulse generating mechanism, and by cooperating with the cutting and loading mechanism and the pulse generating mechanism, the positive electrode sheet can be automatically cut and loaded and pulse-discharged, with a high degree of automation.

[0047] Furthermore, since the plurality of first clamping components are evenly distributed in a ring around the outer circumference of the rotating shaft, the distance between any two adjacent first clamps is equal, so that the lengths of the pole segments automatically cut and loaded to the pulse generating mechanism by the cutting and loading mechanism are the same, which enables the consistency of the processing effect of the pulse discharge treatment of the pole segments using an automated device, thereby making it easier to maintain a better processing effect of the pulse discharge treatment.

[0068] As shown in Figures 1 to 4, the present application provides an automated device 1 for pulse discharge processing of positive electrode sheets 2, comprising a box body 10, a cutting and loading mechanism 11, and a pulse generating mechanism 12. The box body 10 has a cavity 100, and one side of the box body 10 has an opening 101 connected to the cavity 100. The cutting and loading mechanism 11 comprises a first driving member 110, a rotating shaft 111, a plurality of first clamping components 112, and at least one cutting member 113. The first driving member 110 is located on one side of the box body 10. The first driving member 110 can drive the rotating shaft 111 to rotate. The plurality of first clamping components 112 are evenly distributed in a ring around the outer periphery of the rotating shaft 111. The first clamping component 112 comprises a first chuck 112a and an extension 112b. The extension 112b may include but is not limited to a rod-shaped structure and a cylindrical structure. The extension 112b is connected between the first chuck 112a and the rotating shaft 111. The first chuck 112a can clamp the positive electrode sheet 2 and move with it. The rotating shaft 111 rotates to be close to the opening 101, and the cutting piece 113 is arranged near the first clamping head 112a, that is, the cutting piece 113 is arranged close to the first clamping head 112a, and the cutting piece 113 can cut the positive electrode sheet 2, and the pulse generating mechanism 12 includes a second clamping component 120 and a third clamping component 121. The second clamping component 120 and the third clamping component 121 are both at least partially movable relative to the box body 10. The second clamping component 120 and the third clamping component 121 can both clamp the positive electrode sheet 2 through the opening 101 so that the positive electrode sheet 2 can move between the inside and outside of the cavity 100. The second clamping component 120 and the third clamping component 121 can be energized to form a pulse current between the second clamping component 120 and the third clamping component 121.

[0069] By setting a cutting and loading mechanism 11 that can load the positive electrode sheet 2 to a fixed position near the opening 101 and can cut the positive electrode sheet 2 at the fixed position, and a second clamping assembly 120 and a third clamping assembly 121 that can clamp and transport the positive electrode sheet 2 from the fixed position to the cavity 100, the cutting and loading mechanism 11, the second clamping assembly 120 and the third clamping assembly 121 cooperate to realize the automatic cutting of the positive electrode sheet 2 into the electrode segments 20 and loading them to the second clamping assembly Component 120 and the third clamping component 121, so that the second clamping component 120 and the third clamping component 121 apply a pulse current to the electrode segment 20, so that the positive electrode material (not shown in the figure) included in the electrode segment 20 is separated from the positive collector segment 20. In other words, by setting up the cutting and loading mechanism 11 and the pulse generating mechanism 12, and by cooperating with the cutting and loading mechanism 11 and the pulse generating mechanism 12, the positive electrode sheet 2 can be automatically cut and loaded and pulse discharged, with a high degree of automation.

[0070] As shown in Figures 4 to 6, for example, the first driving member 110 can drive the rotating shaft 111 to rotate, so that a first clamping head 112a clamps part of the positive electrode sheet 2 and rotates to the side adjacent to the opening 101, and the end 2a of the positive electrode sheet 2 is located on the side of the first clamping head 112a close to the opening 101, and the second clamping assembly 120 moves relative to the box body 10 to clamp the end 2a of the positive electrode sheet 2, and then the first clamping head 112a releases the positive electrode sheet 2, and the second clamping assembly 120 is reset. At the same time, the first driving member 110 drives the rotating shaft 111 to rotate synchronously, so that the other first clamping head 112a transports the positive electrode sheet 2 to the side adjacent to the opening Opening 101, the third clamping assembly 121 moves relative to the box body 10 to clamp the positive electrode sheet 2 located on the side of the other first clamping head 112a close to the opening 101, and then the cutting piece 113 cuts the positive electrode sheet 2 between the first clamping head 112a and the third clamping assembly 121 to obtain the electrode segment 20, and at this time, the two opposite ends of the electrode segment 20 are clamped by the second clamping assembly 120 and the third clamping assembly 121 respectively. Finally, the third clamping assembly 121 is reset to complete the automatic cutting and loading process of the positive electrode sheet 2.

[0071] During this process, the control chip can be used to control the actions of the cutting and loading mechanism 11 and the pulse generating mechanism 12, so that the cutting and loading mechanism 11 and the pulse generating mechanism 12 can cooperate and work together. The automation device 1 may include the control chip, or the control chip may be connected to an external circuit, and the automation device 1 may be electrically connected to the control chip by electrically connecting to an external circuit.

[0072] Furthermore, since the plurality of first clamping components 112 are evenly distributed in a circular pattern around the outer periphery of the rotating shaft 111, the distance between any two adjacent first clamps 112a is equal, so that the lengths of the pole segments 20 automatically cut and loaded to the pulse generating mechanism 12 by the cutting and loading mechanism 11 are all the same, which enables the consistency of the treatment effect of the pulse discharge treatment of the pole segments 20 using the automated device 1 to be better, thereby making it easier to maintain a better treatment effect of the pulse discharge treatment.

[0073] It should be noted that the box body 10 and the first driving member 110 can be arranged on the same frame (not shown in the figure), or the box body 10 and the first driving member 110 can be arranged on different frames respectively, and the relative position of the box body 10 and the first driving member 110 can be kept stable. In other words, as long as the relative position of the box body 10 and the first driving member 110 can be kept stable, this embodiment does not limit the arrangement of the box body 10 and the first driving member 110.

[0074] The principle of pulse discharge treatment by the automated device 1 on the electrode segment 20 to separate the positive electrode material and the positive current collector segment 200 (see Figure 16) included in the electrode segment 20 is that a large amount of heat is instantly generated in the positive current collector segment 200 by the pulse current, causing part of the positive electrode material to vaporize, and at the same time, breakdown occurs and plasma is formed, so that the positive electrode material is formed into small particles and separated from the positive current collector segment 200. The positive electrode material formed into small particles can be collected in the cavity 100 for recycling.

[0075] In order to prevent vaporized or small-particle positive electrode materials from floating away with the air, resulting in low recovery efficiency and affecting the air quality in the working environment, optionally, the cavity 100 can be filled with a cooling liquid (not shown in the figure), for example, water. During the pulse discharge treatment of the electrode segment 20, the entire electrode segment 20 can be immersed in the cooling liquid under the clamping of the second clamping component 120 and the third clamping component 121, so as to quickly cool the vaporized positive electrode material through the cooling liquid, and make the small-particle positive electrode material dispersed in the cooling liquid, making it difficult for it to enter the air.

[0076] For example, to prevent the cooling liquid in the cavity 100 from spilling out of the opening 101, during use of the automated device 1, the housing 10 can be positioned with the opening 101 facing upward along the direction of gravity. It is understood that when the upper and lower positions are described later in this document, the upper and lower positions refer to the upper and lower positions along the direction of gravity when the housing 10 is positioned with the opening 101 facing upward along the direction of gravity. Therefore, when the opening 101 of the housing 10 is not facing upward along the direction of gravity, the upper and lower positions are not the upper and lower positions along the direction of gravity.

[0077] Optionally, the cutting member 113 may include a fourth driving member 1130 and a blade 1131 . The fourth driving member 1130 may be configured to drive the blade 1131 to translate or rotate, so that the blade 1131 can cut the positive electrode sheet 2 .

[0078] As shown in Figure 12, an exemplary fourth driving member 1130 may include but is not limited to a cylinder, a linear motor and a screw motor. The fourth driving member 1130 is configured to drive the blade 1131 to translate so that the blade 1131 extends from or retracts from the fourth driving member 1130, so that the blade 1131 can cut the positive electrode sheet 2 during the process of extending and retracting from the fourth driving member 1130. At the same time, when the blade 1131 is retracted to the fourth driving member 1130, the distance between the blade 1131 and the positive electrode sheet 2 can be farther, so as to avoid interference between the blade 1131 and the first clamping assembly 112, the second clamping assembly 120 or the third clamping assembly 121 when the first clamping assembly 112 rotates with the rotating shaft 111, or when the second clamping assembly 120 and the third clamping assembly 121 clamp the positive electrode sheet 2.

[0079] As shown in Figures 1, 6 and 7, another exemplary embodiment, the fourth driving member 1130 may include but is not limited to a rotary motor and a hydraulic motor. The fourth driving member 1130 is configured to drive the blade 1131 to rotate, and at least part of the edge of the blade 1131 is formed as a cutting edge 1131a, so that the blade 1131 can cut the positive electrode sheet 2 through the cutting edge 1131a during the rotation process.

[0080] Optionally, the blade 1131 may be a structure in which at least part of the blade edge 1131a gradually moves away from the output shaft of the fourth driving member 1130 along the circumferential direction of the output shaft of the fourth driving member 1130. Thus, when the blade 1131 is driven by the fourth driving member 1130 and rotates around the output shaft of the fourth driving member 1130, the blade edge 1131a of the blade 1131 can gradually approach the positive electrode sheet 2 to cut the positive electrode sheet 2, and the non-blade 1131a of the blade 1131 can be prevented from colliding with the positive electrode sheet 2, so that the blade 1131 can have a better cutting effect on the positive electrode sheet 2, and the edge of the cut electrode segment 20 is straighter.

[0081] Exemplarily, a portion of the edge of the blade 1131 may be formed into a blade 1131a, and the remaining edge may be close to the output shaft of the fourth driving member 1130, so that when the blade 1131 is rotated until the blade 1131a is located on the side of the output shaft away from the positive electrode sheet 2, the distance between the remaining edge and the positive electrode sheet 2 may be farther. In other words, the distance between the cutting member 113 as a whole and the positive electrode sheet 2 may be farther, thereby facilitating the avoidance of interference between the blade 1131 and the first clamping component 112, the second clamping component 120 or the third clamping component 121 when the first clamping component 112 rotates with the rotating shaft 111, or when the second clamping component 120 and the third clamping component 121 clamp the positive electrode sheet 2.

[0082] In other embodiments, the cutting member 113 may further include two blades 1131 , and the fourth driving member 1130 is configured to drive at least one of the two blades 1131 to rotate so that the two blades 1131 can open and close like scissors to cut the positive electrode sheet 2 .

[0083] According to different usage requirements, the cutting member 113 can be arranged in a variety of different positions. The following exemplifies the arrangement positions of two cutting members 113.

[0084] As shown in FIG. 12 and FIG. 14 , optionally, the cutting member 113 is disposed adjacent to the opening 101 , so that the cutting position of the cutting member 113 is fixed and a smaller number of cutting members 113 are required.

[0085] When the cutting member 113 includes the fourth driving member 1130 and the blade 1131 as in the aforementioned technical solution, optionally, the fourth driving member 1130 may be disposed on one side of the box body 10 adjacent to the opening 101 .

[0086] Optionally, the fourth driving member 1130 may be connected to the outer periphery of the box body 10 , thereby facilitating the entirety of the cutting member 113 to be maintained at a position adjacent to the opening 101 .

[0087] Please refer to Figures 1, 6 and 7 again. Alternatively, the cutting and loading mechanism 11 includes a plurality of cutting pieces 11, and the extensions 112b of the plurality of first clamping components 112 are each provided with a cutting piece 113, and the cutting piece 113 is spaced apart from the first clamp 112a. When the first clamp 112a follows the extension 112b and the rotating shaft 111 to rotate near the opening 101, the cutting piece 113 is located between the first clamp 112a and the opening 101, so that the relative position of the cutting piece 113 and the first clamp 112a is relatively fixed, so that after the cutting piece 113 cuts the positive electrode sheet 2, the length of the end 2a of the positive electrode sheet 2 located on the side of the first clamp 112a facing the opening 101 is relatively stable, so as to facilitate clamping by the second clamping component 120.

[0088] When the cutting member 113 includes the fourth driving member 1130 and the blade 1131 as in the aforementioned technical solution, optionally, the fourth driving member 1130 is provided at the extending portion 112 b , and the blade 1131 is connected to the fourth driving member 1130 .

[0089] Please refer to Figures 1, 4 and 5 again. Optionally, the second clamping assembly 120 includes a second clamp 1201 and a second driving member 1202. The second clamp 1201 can clamp the positive electrode sheet 2. The second driving member 1202 is connected between the second clamp 1201 and the box body 10. The second driving member 1202 is configured to drive the second clamp 1201 to move relative to the box body 10, so that the second clamp 1201 can extend from the opening 101 to the cavity 100 to clamp the end 2a of the positive electrode sheet 2, or the second clamp 1201 can return from the opening 101 to the inside of the cavity 100 to reset, and at the same time, can bring the end 2a of the positive electrode sheet 2 into the cavity 100.

[0090] Exemplarily, the second driving member 1202 may include a first telescope 1202a, which may include but is not limited to a cylinder, a linear motor and a screw motor, so that the structure of the second driving member 1202 is relatively simple, and the second driving member 1202 can change the relative distance between the second chuck 1201 and the box body 10, so as to facilitate the movement of the second chuck 1201 between the cavity 100 and the outside of the cavity 100 through the opening 101.

[0091] Since the first clamp 112a can transport the positive electrode sheet 2 to a fixed position adjacent to the opening 101, in an optional example, the end of the second driving member 1202 connected to the second clamp 1201 can be directed to the fixed position, so that the second driving member 1202 can drive the second clamp 1201 to move to the fixed position or return to the cavity 100.

[0092] In another optional example, the second driving member 1202 may further include a first oscillator 1202b, which may include but is not limited to a swing motor and a rotation motor. The first oscillator 1202b is connected between the first telescopic member 1202a and the box 10. The first oscillator 1202b can drive the first telescopic member 1202a to swing relative to the box 10. The end of the first telescopic member 1202a away from the first oscillator 1202b is connected to the second clamp 1201. 2a is configured to drive the second chuck 1201 to approach or move away from the first oscillator 1202b, so that when the second chuck 1201 needs to be moved to the fixed position for loading the first chuck 112a, the first telescopic device 1202a can be driven by the first oscillator 1202b to swing relative to the box body 10, so that the end of the first telescopic device 1202a connected to the second chuck 1201 points to the fixed position, so that the first telescopic device 1202a can be extended to drive the second chuck 1201 to move to the fixed position.

[0093] In other embodiments, the second driving member 1202 may further include a multi-degree-of-freedom robotic arm.

[0094] Please refer to Figures 8 and 9. Optionally, the second clamping assembly 120 also includes a first cable 1203, which is electrically connected between the second clamp 1201 and the external control circuit. The external control circuit can connect the second clamp 1201 to a circuit with a larger current through the first cable 1203, so that the second clamp 1201 can cooperate with the third clamp 1210 to achieve the function of pulse discharge.

[0095] Optionally, the first cable 1203 is partially wound around the outer periphery of the second driving member 1202, and there is a gap between at least part of the first cable 1203 and the outer periphery of the second driving member 1202 (as shown in Figure 8), or a first winding disk 1204 is provided in the second driving member 1202, and the first winding disk 1204 may include but is not limited to a winding disk that does not require a driving member and includes structures such as a torsion spring and a spring leaf, and a winding disk that includes a driving member, the first cable 1203 is partially passed through the interior of the second driving member 1202, and the first cable 1203 is partially wound around the first winding disk 1204, and the first winding disk 1204 can rotate relative to the second driving member 1202 to release part of the first cable 1203, or to release more of the first cable 1203. The cable 1203 is wound around the first winding drum 1204 (as shown in FIG9 ), so that when the second driving member 1202 drives the second clamp 1201 to move relative to the box 10, the first cable 1203 can follow the movement of the second driving member 1202 to avoid the first cable 1203 being wound around other structures included in the automation device 1, causing the first cable 1203 to be pulled or even damaged or broken. For ease of observation, the first cable 1203 shown in FIG8 is thicker and the number of winding turns of the first cable 1203 is less. The structure thickness of the second driving member 1202 shown in FIG9 is larger. Figures 8 and 9 are only used to roughly illustrate the setting method of the first cable 1203, and do not constitute a limitation on the actual thickness of the first cable 1203, and the size relationship between the first cable 1203, the first winding drum 1204 and the second driving member 1202.

[0096] Optionally, the third clamping assembly 121 includes a third clamp 1210 and a third driving member 1211. The third clamp 1210 can clamp the positive electrode sheet 2. The third driving member 1211 is spaced apart from the third driving member 1211. The third driving member 1211 is connected between the third clamp 1210 and the box body 10. The third driving member 1211 is configured to drive the third clamp 1210 to move relative to the box body 10, so that the third clamp 1210 can extend from the opening 101 to the cavity 100 to clamp the positive electrode sheet 2, or the third clamp 1210 can return from the opening 101 to the inside of the cavity 100 to reset, and at the same time, can bring one end of the electrode segment 20 into the cavity 100.

[0097] Exemplarily, the third driving member 1211 may include a second telescopic device 1211a, which may include but is not limited to a cylinder, a linear motor and a screw motor, so that the structure of the third driving member 1211 is relatively simple, and the third driving member 1211 can change the relative distance between the third chuck 1210 and the box body 10, so as to facilitate the movement of the third chuck 1210 between the cavity 100 and the outside of the cavity 100 through the opening 101.

[0098] Since the first clamp 112a can transport the positive electrode sheet 2 to a fixed position adjacent to the opening 101, in an optional example, the end of the third driving member 1211 connected to the third clamp 1210 can be directed to the fixed position, so that the third driving member 1211 can drive the third clamp 1210 to move to the fixed position or return to the cavity 100.

[0099] In another optional example, the third driving member 1211 may also include a second oscillator (not shown in the figure), the second oscillator may include but is not limited to a swing motor and a rotating motor, the second oscillator is connected between the second telescopic device 1211a and the box body 10, the second oscillator can drive the second telescopic device 1211a to swing relative to the box body 10, the end of the second telescopic device 1211a away from the second oscillator is connected to the third clamp 1210, the second telescopic device 1211a is configured to drive the third clamp 1210 to move closer to or away from the second oscillator, so that when the third clamp 1210 needs to be moved to the fixed position for loading the first clamp 112a, the second telescopic device 1211a can be driven by the second oscillator to swing relative to the box body 10, so that the end of the second telescopic device 1211a connected to the third clamp 1210 points to the fixed position, so that the second telescopic device 1211a can be extended to drive the third clamp 1210 to move to the fixed position, wherein the setting of the second oscillator can be seen in Figure 4 The arrangement of the first oscillator 1202b is shown in FIG.

[0100] In other embodiments, the third driving member 1211 may further include a multi-degree-of-freedom robotic arm.

[0101] Optionally, the third clamping assembly 121 also includes a second cable (not shown in the figure), which is electrically connected between the third clamp 1210 and the external control circuit. The external control circuit can connect the third clamp 1210 to a circuit with a larger current through the second cable, so that the third clamp 1210 can cooperate with the second clamp 1201 to realize the function of pulse discharge.

[0102] Optionally, the second cable portion is wound around the outer periphery of the third driving member 1211, or a second winding drum (not shown in the figure) is provided in the third driving member 1211, the second cable portion is passed through the interior of the third driving member 1211, and the second cable portion is wound around the second winding drum, and the second winding drum can rotate relative to the third driving member 1211 to release part of the second cable, or allow more of the second cable to be wound around the second winding drum, so that when the third driving member 1211 drives the third clamp 1210 to move relative to the box 10, the second cable can follow the movement of the third driving member 1211 to avoid the second cable being wound around other structures included in the automation device 1, causing the second cable to be pulled or even damaged or broken. The setting of the second cable can refer to the setting of the first cable 1203 shown in Figure 8, and the setting of the second cable and the second winding drum can refer to the setting of the first cable 1203 and the first winding drum 1204 shown in Figure 9.

[0103] It can be understood that the second clamping component 120 and the third clamping component 121 can respectively select structures according to their own usage requirements. In other words, the structures of the second clamping component 120 and the third clamping component 121 can be the same or different, and the structures of the second clamping component 120 and the third clamping component 121 can respectively refer to the various different embodiments mentioned above.

[0104] It should be noted that the first clamp 112a, the second clamp 1201 and the third clamp 1210 mentioned above are all clamp-like structures that can automatically close to clamp the positive electrode sheet 2 or automatically open to release the positive electrode sheet 2 under the control of the control chip mentioned above. This embodiment does not limit the structure of the first clamp 112a, the second clamp 1201 and the third clamp 1210.

[0105] As shown in Figures 12 and 13, in order to improve the degree of automation of the process of pulse discharge treatment of the positive electrode sheet 2 using the automated device 1, the automated device 1 can also realize the automatic unloading function of the positive current collector segment 200 after the pulse discharge treatment. Optionally, the automated device 1 also includes a receiving structure 13, which may include but is not limited to a receiving tray, a receiving box and other structures. The receiving structure 13 is arranged on one side of the box body 10, and the second clamping assembly 120 or the third clamping assembly 121 can respectively clamp the positive current collector segment 200 through the opening 101 and release the positive current collector segment 200, or the second clamping assembly 120 and the third clamping assembly 121 can synchronously clamp the positive current collector segment 200 through the opening 101 and sequentially or synchronously release the positive current collector segment 200, so that the positive current collector segment 200 falls to the receiving structure 13 accordingly, thereby moving the positive current collector segment 200 to the receiving structure 13 to realize automatic unloading and recovery of the positive current collector segment 200.

[0106] Optionally, the receiving structure 13 and the cutting and loading mechanism 11 are respectively arranged on both sides of the box body 10. In other words, the receiving structure 13 and the cutting and loading mechanism 11 are respectively arranged on two different sides of the box body 10, so that the loading and unloading functions of the automation device 1 are separated, and the receiving structure 13 and the cutting and loading mechanism 11 are not easy to interfere with each other, and the structure of the automation device 1 is more reasonable.

[0107] Please refer to Figures 15 and 16. When, as in the aforementioned technical solution, the second clamping assembly 120 includes a second clamping head 1201 and a second driving member 1202, and the third clamping assembly 121 includes a third clamping head 1210 and a third driving member 1211, for example, the second clamping head 1201 can be rotated relative to the second driving member 1202, and the third clamping head 1210 can be rotated relative to the third driving member 1211, so that the second driving member 1202 and the third driving member 1211 can drive the second clamping head 1201 and the third clamping head 1210 to move, so as to lift the positive collector segment 200 to the top of the opening 101, and then by making the second clamping head 1201 relative to the third driving member 1211, the positive collector segment 200 can be lifted to the top of the opening 101. The second driving member 1202 rotates to rotate the third clamp 1210 relative to the third driving member 1211 to transport the positive collector segment 200 to the top of the receiving structure 13, and then the second clamp 1201 and the third clamp 1210 release the positive collector segment 200 at the same time, or the second clamp 1201 and the third clamp 1210 release the positive collector segment 200 in turn to make the positive collector segment 200 fall onto the receiving structure 13. For ease of observation, the cross-sectional view obtained along the CC direction of Figure 14 is adjusted in Figure 15 to a posture where the opening 101 of the box body 10 is facing the top of the picture. It should be noted that the third clamp 1210 in Figure 16 is blocked by the second clamp 1201.

[0108] Optionally, the automated device 1 may further include a detector 15 and a lifting mechanism 130. The detector 15 is provided on one side of the box body 10 close to the receiving structure 13. The lifting mechanism 130 supports the receiving structure 13, and the lifting mechanism 130 is electrically connected to the detector 15. When the detector 15 detects that the actual relative height of the positive collector segment 200 carried by the receiving structure 13 and the box body 10 exceeds a predetermined height, the lifting mechanism 130 can drive the receiving structure 13 to descend, so that the difference in the falling distance of each positive collector segment 200 falling to the receiving structure 13 is smaller, thereby making the posture of each positive collector segment 200 on the receiving structure 13 more consistent, so that multiple positive collector segments 200 can be more neatly stacked on the receiving structure 13.

[0109] Optionally, the detector 15 may include but is not limited to a distance detector 15 and an image collector. The detector 15 may be arranged on the periphery of the box body 10, so as to facilitate fixing the relative height between the detector 15 and the box body 10, so as to facilitate the detection of the actual relative height between the positive collector segment 200 supported by the containing structure 13 and the box body 10 by the detector 15.

[0110] Exemplarily, the detector 15 may include a distance detector 15. In this case, when the actual relative height between the positive collector segment 200 carried by the containing structure 13 and the box body 10 is lower than the height at which the detector 15 is located, the distance to the nearest object detected by the detector 15 is greater than a distance threshold; when the actual relative height between the positive collector segment 200 carried by the containing structure 13 and the box body 10 is flush with or higher than the height at which the detector 15 is located, the distance to the nearest object detected by the detector 15 is less than the distance threshold.

[0111] Optionally, when the detector 15 detects that the relative height between the positive collector segment 200 carried by the containment structure 13 and the box body 10 exceeds a predetermined height, the lifting mechanism 130 can lower the containment structure 13 to a predetermined height. In other words, each time the detector 15 detects that the relative height between the positive collector segment 200 carried by the containment structure 13 and the box body 10 exceeds a predetermined height, the lifting mechanism 130 is only set to lower the containment structure 13 to the same height, thereby improving the controllability of the falling distance range of each positive collector segment 200 falling onto the containment structure 13.

[0112] Optionally, the control chip described in the aforementioned technical solution can be used to receive the actual relative height detected by the detector 15, and when the actual relative height is higher than a predetermined height, the control chip can be used to cause the lifting mechanism 130 to drive the receiving structure 13 to descend.

[0113] Please refer to Figures 1 and 3 again. Alternatively, the cavity 100 has a bottom 100a away from the opening 101. The automation device 1 also includes a receiving structure 13 and a conveyor belt assembly 14. The receiving structure 13 may include but is not limited to a receiving tray, a receiving box, etc. The receiving structure 13 is provided on one side of the box body 10. The conveyor belt assembly 14 has a first end 140 and a second end 141 opposite to each other. The first end 140 corresponds to the second clamping assembly 120 and the third clamping assembly 121 and is provided at the bottom 10. 0a, the second end 141 is set corresponding to the receiving structure 13, the first end 140 of the conveyor belt assembly 14 can receive the positive collector segment 200 dropped from the second clamping assembly 120 and the third clamping assembly 121, and the conveyor belt assembly 14 can transport the positive collector segment 200 to the receiving structure 13. For example, the conveyor belt assembly 14 can transport the positive collector segment 200 from the first end 140 to the second end 141, and can make the positive collector segment 200 drop from the second end 141 to the receiving structure 13.

[0114] Optionally, the receiving structure 13 and the cutting and loading mechanism 11 are respectively arranged on both sides of the box body 10. In other words, the receiving structure 13 and the cutting and loading mechanism 11 are respectively arranged on two different sides of the box body 10, so that the loading and unloading functions of the automation device 1 are separated, and the receiving structure 13 and the cutting and loading mechanism 11 are not easy to interfere with each other, and the structure of the automation device 1 is more reasonable.

[0115] Please refer to Figures 10 and 11. For example, the conveyor belt assembly 14 includes a bracket 142, multiple rollers 143, a fifth driving member (not shown in the figure) and a belt body 144. The bracket 142 has a first end 140 and a second end 141. The multiple rollers 143 are arranged at intervals on the bracket 142, and the first end 140 and the second end 141 are both provided with rollers 143. The fifth driving member can drive at least one roller 143 to rotate. The belt body 144 is integrally arranged around the bracket 142 and the multiple rollers 143, and the rollers 143 can drive the belt body 144 to move, so that the positive collector segment 200 that falls to the first end 140 can be transported from the first end 140 to the second end 141 through the belt body 144, and the positive collector segment 200 can be dropped from the second end 141 to the receiving structure 13.

[0116] Optionally, the roller 143 may be tightly connected to the belt body 144 so that the roller 143 drives the belt body 144 to move through the friction between the roller 143 and the belt body 144, or the roller 143 may include a gear-like structure, and the belt body 144 may include a rack-like structure, so that the roller 143 and the belt body 144 can be detachably connected through a gear-and-rack-like structure, so that the roller 143 can drive the belt body 144 to move.

[0117] Optionally, when the conveyor belt assembly 14 includes multiple rollers 143, two rollers 143 among the multiple rollers 143 may be the same or different, as shown in Figure 10, which exemplarily shows that the conveyor belt assembly 14 includes three rollers 143, one of which is a structure tightly connected to the belt body 144, and the other two rollers 143 are gear-like structures.

[0118] Optionally, a first concave-convex structure 142a is provided on one side of the belt body 144 facing the bracket 142, and a second concave-convex structure 144a is provided on at least the first end 140 of the bracket 142 corresponding to the first concave-convex structure 142a. The first concave-convex structure 142a and the second concave-convex structure 144a are movably abutted against each other, so that when the roller 143 drives the belt body 144 to move around the belt body 144 and the bracket 142 as a whole, the first concave-convex structure 142a and the second concave-convex structure 144a are movably abutted against each other, so that at least a portion of the belt body 144 corresponding to the first concave-convex structure 142a can vibrate toward or away from the bracket 142, thereby driving the positive current collector segment 200 located at at least the first end 140 to vibrate in the cooling liquid, so that the positive electrode material attached to the surface of the positive current collector segment 200 is dispersed into the cooling liquid, thereby improving the separation and recovery efficiency of the electrode segments 20 using the automated device 1 for material separation and recovery.

[0119] When the belt body 144 includes a rack-like structure as in the aforementioned technical solution, the second concave-convex structure 144a can be formed into the rack-like structure, thereby allowing the second concave-convex structure 144a to be structurally reused, making the structure of the conveyor belt assembly 14 more compact.

[0120] When, as in the aforementioned technical solution, the roller 143 can be tightly connected to the belt body 144 so that the roller 143 drives the belt body 144 to move through the friction between the roller 143 and the belt body 144, the outer periphery of the roller 143 can be provided with an avoidance groove 143a corresponding to the second concave-convex structure 144a, so that the second concave-convex structure 144a can be avoided to prevent the second concave-convex structure 144a from affecting the tight connection between the roller 143 and the belt body 144, thereby avoiding the situation where the driving effect of the roller 143 on the belt body 144 fails due to the second concave-convex structure 144a.

[0121] Optionally, a plurality of spaced baffles 144b may be provided on the belt body 144 to limit the positive current collector segment 200 from falling to the position of the belt body 144 located at the first end 140 through the baffles 144b, thereby improving the reliability of the process of transporting the positive current collector segment 200 through the belt body 144 to drop into the receiving structure 13.

[0122] Optionally, the automation device 1 may further include a detector 15 and a lifting mechanism 130. In this case, the configuration of the detector 15 and the lifting mechanism 130 and the corresponding effects can be found in the aforementioned technical solution and will not be repeated here.

[0123] As shown in FIG3 to FIG6 and FIG17, the present application also provides a method for treating a positive electrode sheet 2 by pulse discharge, which can use the automated device 1 provided in the aforementioned technical solution to perform a highly automated pulse discharge treatment on the positive electrode sheet 2, so as to efficiently perform pulse discharge treatment on the positive electrode sheet 2. The treatment method includes the following steps:

[0124] Step S1: The first driving member 110 drives the rotating shaft 111 to rotate, so that the first clamping head 112a clamping the positive electrode sheet 2 rotates to be close to the opening 101, and the end 2a of the positive electrode sheet 2 is located on the side of the first clamping head 112a close to the opening 101;

[0125] Step S2: The second clamping assembly 120 moves relative to the box 10 to clamp the end 2a of the positive electrode sheet 2;

[0126] Step S3: a first clamp 112a releases the positive electrode sheet 2;

[0127] Step S4: The second clamping assembly 120 moves relative to the housing 10 to allow the end 2a of the positive electrode sheet 2 to enter the cavity 100. The first driving member 110 synchronously drives the rotating shaft 111 to rotate, so that the other first clamping head 112a clamps another portion of the positive electrode sheet 2 and rotates to the vicinity of the opening 101.

[0128] Step S5: The third clamping assembly 121 moves relative to the box body 10 to clamp the positive electrode sheet 2 located on the side of the other first clamping head 112 a close to the opening 101 ;

[0129] Step S6: The cutting member 113 cuts the positive electrode sheet 2 between the other first clamping head 112a and the third clamping assembly 121 to obtain a electrode segment 20. The two ends of the electrode segment 20 are clamped by the second clamping assembly 120 and the third clamping assembly 121 respectively.

[0130] Optionally, after step S5 and before step S6, the processing method further includes:

[0131] In step S5a, the third clamping assembly 121 moves in a direction away from the other first clamping head 112a, so as to tighten the positive electrode sheet 2 between the other first clamping head 112a and the third clamping assembly 121.

[0132] This facilitates the cutting piece 113 to cut the positive electrode sheet 2 located between the other first clamping head 112 a and the third clamping assembly 121 , and improves the reliability of the cutting process of the positive electrode sheet 2 by the cutting piece 113 .

[0133] Step S7: The third clamping assembly 121 moves relative to the box body 10 so that the entire electrode segment 20 enters the cavity 100;

[0134] Step S8: energize the second clamping assembly 120 and the third clamping assembly 121 so that the pulse current flows to the pole segment 20, and the positive electrode material included in the pole segment 20 is separated from the positive collector segment 200. The two ends of the positive collector segment 200 are clamped by the second clamping assembly 120 and the third clamping assembly 121 respectively.

[0135] Step S9: Recover the positive current collector segment 200.

[0136] Referring to FIG. 15 and FIG. 16 , when the automation device 1 further includes a receiving structure 13 as described in the aforementioned technical solution, optionally, step S9 further includes:

[0137] In step S90 , the second clamping assembly 120 and the third clamping assembly 121 are both movable relative to the housing 10 , so that the positive current collector segment 200 is separated from the cavity 100 through the opening 101 and corresponds to the receiving structure 13 ;

[0138] Step S91: The second clamping assembly 120 and the third clamping assembly 121 both release the positive current collector segment 200, causing the positive current collector segment 200 to fall onto the receiving structure 13;

[0139] Referring to FIG. 10 and FIG. 11 , when the automation device 1 further includes a receiving structure 13 and a conveyor belt assembly 14 as described in the aforementioned technical solution, another option is that step S9 further includes:

[0140] In step S90 ′, the second clamping assembly 120 and the third clamping assembly 121 both release the positive current collector segment 200 , causing the positive current collector segment 200 to fall onto the conveyor assembly 14 .

[0141] Step S91 ′: the conveyor assembly 14 transports the positive current collector segment 200 from the cavity 100 to the outside of the cavity 100 ;

[0142] In step S92 ′, the conveyor assembly 14 continues to transport the positive current collector segment 200 until the positive current collector segment 200 falls onto the receiving structure 13 from the end of the conveyor assembly 14 away from the cavity 100 .

[0143] When the automation device 1 further includes a detector 15 and a lifting mechanism 130 as described in the above technical solution, after step S9, the processing method further includes:

[0144] In step S9a, the detector 15 detects the actual relative height between the positive current collector section 200 supported by the receiving structure 13 and the box body 10 .

[0145] If the actual relative height is greater than the predetermined height, step S9b is executed to cause the lifting mechanism 130 to drive the receiving structure 13 to descend.

[0146] Therefore, the difference in the falling distance of each positive collector segment 200 when falling onto the receiving structure 13 is small, which can make the posture of each positive collector segment 200 on the receiving structure 13 more consistent, so that multiple positive collector segments 200 can be stacked more neatly on the receiving structure 13.
