Technical Field
[0001] This application relates to the field of positive electrode processing technology for batteries, and for example to an automated device and method for pulse discharge processing of positive electrode sheets. Background Technology
[0002] With the development of new energy technologies, the demand for batteries has surged. However, due to the short lifespan of batteries, the number of discarded batteries has also increased dramatically. Therefore, to save 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. One common technology involves using pulse discharge to treat the positive electrode sheet, separating the positive electrode material and the positive current collector for recycling.
[0003] However, current pulse discharge processing devices require the positive electrode sheet to be cut and then manually loaded, which cannot achieve automatic cutting and loading of the positive electrode sheet, resulting in low automation and low production efficiency. Summary of the Invention

[0017] The third clamping assembly further includes a second cable, which is electrically connected between the third clamp and the external control circuit.

[0019] The cutting and feeding mechanism includes a plurality of cutting components, and the extensions of the plurality of first clamping assemblies are provided with the cutting components, and the cutting components are spaced apart from the first clamps.
[0020] As an optional technical solution for the automated device for pulse discharge processing of the positive electrode sheet, the cutting component includes a fourth driving component and a blade. The fourth driving component is disposed on one side of the housing near the opening, or the fourth driving component is disposed on the extension. The blade is connected to the fourth driving component. The fourth driving component is configured to drive the blade to translate or rotate so that the blade can cut the positive electrode sheet.
[0021] As an optional technical solution for the automated device for pulse discharge processing of the positive electrode sheet, the automated device further includes a receiving structure, which is respectively located on both sides of the housing with the cutting and feeding mechanism. The second clamping assembly and / or the third clamping assembly can both move the positive current collector section to the receiving structure.
[0022] As an optional technical solution for the automated device for pulse discharge processing of positive electrode sheets, the cavity has a bottom away from the opening. The automated device also includes a receiving structure and a conveyor belt assembly. The receiving structure and the cutting and feeding mechanism are respectively located on both sides of the housing. The conveyor belt assembly has a first end and a second end opposite to each other. The first end corresponds to the second clamping assembly and the third clamping assembly and is located at the bottom. The second end corresponds to the receiving structure. The first end of the conveyor belt assembly can receive the positive current collector segment that falls from the second clamping assembly and the third clamping assembly.

The first concave-convex structure and the second concave-convex structure are movably abutting against each other.
[0025] As an optional technical solution for the automated device for pulse discharge processing of the positive electrode sheet, the automated device further includes a detector and a lifting mechanism. The detector is located on the side of the housing near the receiving structure. The lifting mechanism supports the receiving structure and is electrically connected to the detector. When the detector detects that the actual relative height between the positive current collector section carried by the receiving structure and the housing exceeds a predetermined height, the lifting mechanism can drive the receiving structure to descend.
[0026] Secondly, a method for processing a positive electrode sheet using pulse discharge is provided, wherein the positive electrode sheet is subjected to pulse discharge processing using the automated device described in the foregoing technical solution, and the processing method includes the following steps:
[0027] Step S1: The first driving member drives the rotating shaft to rotate, causing a portion of the positive electrode plate held by the first chuck to rotate to a position close to the opening, with the end of the positive electrode plate located on the side of the first chuck closer to the opening.
[0028] Step S2: The second clamping assembly moves relative to the housing to clamp the end of the positive electrode sheet;
[0029] Step S3: The first clamp releases the positive electrode plate;
[0030] Step S4: The second clamping assembly moves relative to the housing so that the end of the positive electrode sheet enters the cavity. The first driving member synchronously drives the rotating shaft to rotate so that another first chuck clamps another part of the positive electrode sheet and rotates it to be close to the opening.
[0031] Step S5: The third clamping assembly moves relative to the housing to clamp the positive electrode sheet located on the side of another first clamp near the opening;
[0032] Step S6: The cutting component cuts the positive electrode sheet located between another first clamp and the third clamping assembly to obtain an electrode segment. The two ends of the electrode segment are respectively clamped by the second clamping assembly and the third clamping assembly.
[0033] Step S7: The third clamping assembly moves relative to the housing so that the entire pole piece enters the cavity;
[0034] Step S8: Power on the second clamping assembly and the third clamping assembly so that the pulse current flows to the electrode segment. The positive electrode material of the electrode segment is separated from the positive current collector segment, and the two ends of the positive current collector segment are clamped by the second clamping assembly and the third clamping assembly, respectively.
[0035] As an optional technical solution to the pulse discharge treatment method for the positive electrode sheet, after step S5 and before step S6, the treatment method further includes:
[0036] Step S5a: The third clamping assembly moves away from the other first clamp to tighten the positive electrode sheet located between the other first clamp and the third clamping assembly.
[0037] As an optional technical solution for the pulse discharge processing method for the positive electrode sheet, the automated device further includes a housing structure, and after step S8, the processing method further includes:
[0038] Step S90: Both the second clamping assembly and the third clamping assembly are movable relative to the housing, so that the positive current collector section disengages from the cavity through the opening and corresponds to the receiving structure;
[0039] Step S91: Both the second clamping assembly and the third clamping assembly release the positive current collector section, causing the positive current collector section to fall onto the receiving structure;
[0040] Alternatively, the automated device may further include a housing structure and a conveyor belt assembly, and after step S8, the processing method may further include:
[0041] Step S90': Both the second clamping assembly and the third clamping assembly release the positive current collector section, causing the positive current collector section to fall onto the conveyor belt assembly;
[0042] Step S91': The conveyor belt assembly transports the positive current collector section from inside the cavity to outside the cavity;
[0043] Step S92': The conveyor belt assembly continues to transport the positive fluid collector segment until the positive fluid collector segment falls from the end of the conveyor belt assembly away from the cavity onto the receiving structure.
[0044] The beneficial effects of this application are as follows:
[0045] By setting up a cutting and feeding mechanism that can feed the positive electrode sheet to a fixed position near the opening and cut the positive electrode sheet at that 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 into the cavity, the cutting and feeding mechanism, the second clamping assembly and the third clamping assembly can cooperate to realize the automatic cutting of the positive electrode sheet into electrode segments and feeding 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 segments, thereby separating the positive electrode material included in the electrode segments from the positive current collector segment. In other words, by setting up a cutting and feeding mechanism and a pulse generating mechanism, and by the cutting and feeding mechanism and the pulse generating mechanism cooperating with the pulse generating mechanism, the positive electrode sheet can be automatically cut and fed and pulsed discharged, with a high degree of automation.
[0046] Furthermore, since multiple first clamping components are evenly distributed in a ring around the outer periphery of the rotating shaft, the distance between any two adjacent first clamps is equal. As a result, the length of the pole segments automatically cut and fed to the pulse generating mechanism by the cutting and feeding mechanism is the same, which makes the processing effect of pulse discharge processing of the pole segments by the automated device more consistent and thus makes it easier to maintain a good processing effect of pulse discharge processing.

[0069] like Figures 1 to 4 As shown, this application provides an automated device 1 for pulse discharge processing of a positive electrode sheet 2, including a housing 10, a cutting and feeding mechanism 11, and a pulse generating mechanism 12. The housing 10 has a cavity 100, and one side of the housing 10 has an opening 101 communicating with the cavity 100. The cutting and feeding mechanism 11 includes a first driving member 110, a rotating shaft 111, a plurality of first clamping assemblies 112, and at least one cutting member 113. The first driving member 110 is located on one side of the housing 10 and can drive the rotating shaft 111 to rotate. The plurality of first clamping assemblies 112 are evenly distributed in a ring around the outer periphery of the rotating shaft 111. The first clamping assembly 112 includes 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 it with the rotating shaft 111. The rotating shaft 111 rotates to be close to the opening 101. The cutting component 113 is disposed near the first chuck 112a, that is, the cutting component 113 is disposed adjacent to the first chuck 112a, and the cutting component 113 can cut the positive electrode 2. The pulse generating mechanism 12 includes a second clamping assembly 120 and a third clamping assembly 121. Both the second clamping assembly 120 and the third clamping assembly 121 are at least partially movable relative to the housing 10. Both the second clamping assembly 120 and the third clamping assembly 121 can clamp the positive electrode 2 through the opening 101 so that the positive electrode 2 can move between the inside and outside of the cavity 100. The second clamping assembly 120 and the third clamping assembly 121 can be energized to form a pulse current between the second clamping assembly 120 and the third clamping assembly 121.
[0070] By setting up a cutting and feeding mechanism 11 that can feed the positive electrode 2 to a fixed position near the opening 101 and cut the positive electrode 2 at that fixed position, and a second clamping assembly 120 and a third clamping assembly 121 that can clamp and transport the positive electrode 2 from the fixed position into the cavity 100, the cutting and feeding mechanism 11, the second clamping assembly 120 and the third clamping assembly 121 cooperate to realize the automatic cutting of the positive electrode 2 into electrode segments 20 and feeding them to the second clamping assembly. The second clamping assembly 120 and the third clamping assembly 121 are used to apply pulse current to the electrode segment 20, thereby separating the positive electrode material (not shown in the figure) included in the electrode segment 20 from the positive current collector segment 200. In other words, by setting the cutting and feeding mechanism 11 and the pulse generating mechanism 12, and by cooperating the cutting and feeding mechanism 11 and the pulse generating mechanism 12, the positive electrode sheet 2 can be automatically cut and fed and pulsed discharged, with a high degree of automation.
[0071] like Figures 4 to 6As shown, exemplarily, the first driving member 110 can drive the rotating shaft 111 to rotate, causing a first chuck 112a to hold a portion of the positive electrode 2 and rotate it to be close to the opening 101, with the end 2a of the positive electrode 2 located on the side of the first chuck 112a near the opening 101. The second clamping assembly 120 moves relative to the housing 10 to clamp the end 2a of the positive electrode 2. Then, the first chuck 112a releases the positive electrode 2, the second clamping assembly 120 resets, and simultaneously, the first driving member 110 drives the rotating shaft 111 to rotate synchronously, causing the other first chuck 112a to rotate. 2a transports the positive electrode 2 to a position near the opening 101. The third clamping assembly 121 moves relative to the housing 10 to clamp the positive electrode 2 located on the side near the opening 101 of the other first clamp 112a. Then, the cutting member 113 cuts the positive electrode 2 between the first clamp 112a and the third clamping assembly 121 to obtain the electrode segment 20. 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, thus completing the automatic cutting and feeding process of the positive electrode 2.
[0072] During this process, the actions of the cutting and feeding mechanism 11 and the pulse generating mechanism 12 can be controlled by the control chip so that the cutting and feeding mechanism 11 and the pulse generating mechanism 12 can cooperate and link together. The automation device 1 may include the control chip, or the control chip may be connected to an external circuit. The automation device 1 can be electrically connected to the control chip by electrically connecting to the external circuit.
[0073] Furthermore, since the multiple first clamping components 112 are evenly distributed around the outer periphery of the rotating shaft 111, the distance between any two adjacent first clamps 112a is equal. As a result, the length of the pole segments 20 automatically cut and fed to the pulse generating mechanism 12 by the cutting and feeding mechanism 11 is the same. This makes it easier to maintain a good consistency in the processing effect of pulse discharge processing on the pole segments 20 using the automated device 1.
[0074] It should be noted that the housing 10 and the first driving component 110 can be mounted on the same rack (not shown in the figure), or the housing 10 and the first driving component 110 can be mounted on different racks, and the relative positions of the housing 10 and the first driving component 110 can be kept stable. In other words, as long as the relative positions of the housing 10 and the first driving component 110 can be kept stable, the arrangement of the housing 10 and the first driving component 110 is not limited in this embodiment.
[0075] The automated device 1 performs pulse discharge processing on the electrode segment 20 to separate the positive electrode material and the positive current collector segment 200 included in the electrode segment 20 (see [link]). Figure 16The principle is that a large amount of heat is generated instantaneously in the positive current collector section 200 by pulsed current, which causes some of the positive electrode material to vaporize, and at the same time, breakdown and plasma are generated, so that the positive electrode material is formed into small particles and detached from the positive current collector section 200. The positive electrode material formed into small particles can be collected in the cavity 100 for recycling.
[0076] To prevent vaporized or small-particle positive electrode materials from drifting away with the air, which would lead to low recovery efficiency and affect air quality in the working environment, the cavity 100 may optionally be filled with a cooling liquid (not shown in the figure), such as water. During the pulse discharge process of the electrode segment 20, the entire electrode segment 20 can be immersed in the cooling liquid under the clamping of the second clamping assembly 120 and the third clamping assembly 121, so as to quickly cool down the vaporized positive electrode material through the cooling liquid and disperse the small-particle positive electrode material in the cooling liquid, making it difficult for it to enter the air.
[0077] For example, to prevent the cooling liquid inside the cavity 100 from spilling out of the opening 101, during the use of the automation device 1, the housing 10 can be positioned with the opening 101 facing upwards along the direction of gravity. It is understood that, in the following description of the upward and downward orientation, this refers to the upward and downward orientation along the direction of gravity when the housing 10 is positioned with the opening 101 facing upwards along the direction of gravity. Therefore, when the opening 101 of the housing 10 does not face upwards along the direction of gravity, this upward and downward orientation is not the upward and downward orientation along the direction of gravity.
[0078] 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.
[0079] like Figure 12 As shown, in one exemplary embodiment, the fourth driving member 1130 may include, but is not limited to, a cylinder, a linear motor, and a lead screw motor. The fourth driving member 1130 is configured to drive the blade 1131 to translate, so that the blade 1131 extends out of or retracts from the fourth driving member 1130. Thus, the blade 1131 can cut the positive electrode 2 during the extension and retraction of the fourth driving member 1130. At the same time, when the blade 1131 retracts from the fourth driving member 1130, the distance between the blade 1131 and the positive electrode 2 can be relatively large, 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 2.
[0080] like Figure 1 , Figure 6 as well as Figure 7 As shown, in another exemplary embodiment, the fourth drive member 1130 may include, but is not limited to, a rotary motor and a hydraulic motor. The fourth drive member 1130 is configured to drive the blade 1131 to rotate. At least a portion of the edge of the blade 1131 is formed as a cutting edge 1131a, so that the blade 1131 can cut the positive electrode plate 2 through the cutting edge 1131a during rotation.
[0081] Optionally, the blade 1131 may have a structure in which at least a portion of the cutting edge 1131a gradually moves away from the output shaft of the fourth drive member 1130 along the circumferential direction of the output shaft of the fourth drive member 1130. Thus, when the blade 1131 rotates around the output shaft of the fourth drive member 1130 under the drive of the fourth drive member 1130, the cutting edge 1131a of the blade 1131 can gradually approach the positive electrode plate 2 to cut the positive electrode plate 2. This can prevent the non-cutting edge 1131a of the blade 1131 from colliding with the positive electrode plate 2, thereby enabling the blade 1131 to cut the positive electrode plate 2 better and the edge of the cut electrode segment 20 to be straighter.
[0082] For example, the blade 1131 may have a portion of its edge formed as a cutting edge 1131a, and the remaining edge is close to the output shaft of the fourth drive member 1130. Thus, when the blade 1131 rotates to the point where the cutting edge 1131a is located on the side of the output shaft away from the positive electrode 2, the distance between the remaining edge and the positive electrode 2 can be relatively large. In other words, the distance between the cutting member 113 as a whole and the positive electrode 2 can be relatively large, thereby making it easier 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 2.
[0083] In other embodiments, the cutting member 113 may also 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.
[0084] Depending on the different usage requirements, the cutting element 113 can have a variety of different settings. The following are two examples of the settings of the cutting element 113.
[0085] like Figure 12 and Figure 14 As shown, alternatively, the cutting element 113 is positioned adjacent to the opening 101, thereby fixing the cutting position of the cutting element 113 and requiring a smaller number of cutting elements 113.
[0086] When the cutting component 113 includes a fourth driving component 1130 and a blade 1131 as described in the aforementioned technical solution, the fourth driving component 1130 may optionally be disposed on one side of the housing 10 adjacent to the opening 101.
[0087] Optionally, the fourth drive member 1130 may be connected to the outer periphery of the housing 10, thereby making it easy to keep the cutter 113 in a position close to the opening 101.
[0088] Please see again Figure 1 , Figure 6 as well as Figure 7 Alternatively, the cutting and feeding mechanism 11 includes multiple cutting elements 11, and each extension 112b of the multiple first clamping assemblies 112 is provided with a cutting element 113. The cutting element 113 is spaced apart from the first chuck 112a. When the first chuck 112a rotates with the extension 112b and the rotating shaft 111 to the vicinity of the opening 101, the cutting element 113 is located between the first chuck 112a and the opening 101. Thus, the relative position of the cutting element 113 and the first chuck 112a is relatively fixed, which makes the length of the end 2a of the positive electrode 2 facing the opening 101 side of the first chuck 112a relatively stable after the cutting element 113 cuts the positive electrode 2, so as to facilitate the second clamping assembly 120 to clamp it.
[0089] When the cutting member 113 includes a fourth driving member 1130 and a blade 1131 in the aforementioned technical solution, the fourth driving member 1130 may be disposed in the extension 112b, and the blade 1131 may be connected to the fourth driving member 1130.
[0090] Please see again Figure 1 , Figure 4 as well as Figure 5 Optionally, the second clamping assembly 120 includes a second clamp 1201 and a second drive member 1202. The second clamp 1201 is capable of clamping the positive electrode 2. The second drive member 1202 is connected between the second clamp 1201 and the housing 10. The second drive member 1202 is configured to drive the second clamp 1201 to move relative to the housing 10, so that the second clamp 1201 can extend out of the cavity 100 from the opening 101 to clamp the end 2a of the positive electrode 2, or to allow the second clamp 1201 to return from the opening 101 to the inside of the cavity 100 for reset. At the same time, it can bring the end 2a of the positive electrode 2 into the cavity 100.
[0091] For example, the second drive member 1202 may include a first telescopic member 1202a, which may include, but is not limited to, a cylinder, a linear motor, and a lead screw motor. Thus, the structure of the second drive member 1202 is relatively simple, and the second drive member 1202 can change the relative distance between the second chuck 1201 and the housing 10, so that the second chuck 1201 can move between the cavity 100 and the outside of the cavity 100 through the opening 101.
[0092] Since the first chuck 112a can transport the positive electrode 2 to a fixed position near the opening 101, in an optional example, one end of the second drive member 1202 connected to the second chuck 1201 can be directed to the fixed position, so that the second drive member 1202 can drive the second chuck 1201 to move to the fixed position or return to the cavity 100.
[0093] In another alternative example, the second drive unit 1202 may further include a first oscillator 1202b, which may include, but is not limited to, an oscillating motor and a rotary motor. The first oscillator 1202b is connected between the first telescopic member 1202a and the housing 10. The first oscillator 1202b can drive the first telescopic member 1202a to oscillate relative to the housing 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 move closer to or further away from the first oscillator 1202b. Thus, when it is necessary to move the second chuck 1201 to the fixed position for loading the first chuck 112a, the first oscillator 1202b can drive the first telescopic device 1202a to swing relative to the housing 10, so that one end of the first telescopic device 1202a connected to the second chuck 1201 points to the fixed position, thereby allowing the first telescopic device 1202a to extend and drive the second chuck 1201 to move to the fixed position.
[0094] In other embodiments, the second drive 1202 may also include a multi-degree-of-freedom robotic arm.
[0095] Please combine Figure 8 and Figure 9 As shown, optionally, the second clamping assembly 120 further 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 large current through the first cable 1203, so that the second clamp 1201 can cooperate with the third clamp 1210 to realize the function of pulse discharge.
[0096] Optionally, the first cable 1203 is partially wound around the outer periphery of the second drive member 1202, and at least a portion of the first cable 1203 has a gap with the outer periphery of the second drive member 1202 (e.g., Figure 8 (As shown), or, the second driving member 1202 is provided with a first winding disc 1204. The first winding disc 1204 may include, but is not limited to, a winding disc without a driving member that includes structures such as torsion springs and leaf springs, as well as a winding disc 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 disc 1204. The first winding disc 1204 can rotate relative to the second driving member 1202 to release part of the first cable 1203, or to allow more of the first cable 1203 to be wound around the first winding disc 1204 (e.g., as shown). Figure 9 As shown), when the second drive member 1202 drives the second clamp 1201 to move relative to the housing 10, the first cable 1203 can follow the movement of the second drive member 1202, so as to avoid the first cable 1203 from getting tangled in other structures included in the automation device 1, which would cause the first cable 1203 to be pulled or even damaged or broken. For ease of observation, Figure 8 The first cable 1203 shown is thicker and has fewer turns. Figure 9 The second drive component 1202 shown in the diagram has a relatively large structural thickness. Figure 8 and Figure 9 This is only intended to roughly illustrate the arrangement of the first cable 1203, and does not constitute a limitation on the actual thickness of the first cable 1203, or the dimensional relationship between the first cable 1203, the first winding reel 1204, and the second drive member 1202.
[0097] Optionally, the third clamping assembly 121 includes a third clamp 1210 and a third drive member 1211. The third clamp 1210 is capable of clamping the positive electrode 2. The third drive member 1211 is spaced apart from the third clamp 1210 and connected between the third clamp 1210 and the housing 10. The third drive member 1211 is configured to drive the third clamp 1210 to move relative to the housing 10, so that the third clamp 1210 can extend out of the cavity 100 from the opening 101 to clamp the positive electrode 2, or, so that the third clamp 1210 can return from the opening 101 to the inside of the cavity 100 to reset. At the same time, it can bring one end of the electrode segment 20 into the cavity 100.
[0098] For example, the third drive member 1211 may include a second telescopic member 1211a, which may include, but is not limited to, a cylinder, a linear motor, and a lead screw motor. Thus, the structure of the third drive member 1211 is relatively simple, and the third drive member 1211 can change the relative distance between the third chuck 1210 and the housing 10, so that the third chuck 1210 can move between the cavity 100 and the outside of the cavity 100 through the opening 101.
[0099] Since the first chuck 112a can transport the positive electrode 2 to a fixed position near the opening 101, in an optional example, one end of the third drive member 1211 connected to the third chuck 1210 can be directed to the fixed position, so that the third drive member 1211 can drive the third chuck 1210 to move to the fixed position or return to the cavity 100.
[0100] In another alternative example, the third drive member 1211 may further include a second oscillator (not shown in the figure). The second oscillator may include, but is not limited to, an oscillating motor and a rotary motor. The second oscillator is connected between the second telescopic member 1211a and the housing 10. The second oscillator can drive the second telescopic member 1211a to oscillate relative to the housing 10. The end of the second telescopic member 1211a away from the second oscillator is connected to the third chuck 1210. The second telescopic member 1211a is configured to drive the third chuck 1210 closer to or further away from the second oscillator. Thus, when it is necessary to move the third chuck 1210 to the fixed position for loading the first chuck 112a, the second oscillator can drive the second telescopic member 1211a to oscillate relative to the housing 10, so that the end of the second telescopic member 1211a connected to the third chuck 1210 points to the fixed position, thereby allowing the second telescopic member 1211a to extend and move the third chuck 1210 to the fixed position. The configuration of the second oscillator can be found in [reference needed]. Figure 4 The configuration of the first oscillator 1202b is shown in the figure.
[0101] In other embodiments, the third drive 1211 may also include a multi-degree-of-freedom robotic arm.
[0102] Optionally, the third clamping assembly 121 further 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 large 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.
[0103] Optionally, the second cable portion is wound around the outer periphery of the third drive member 1211, or the third drive member 1211 is provided with a second winding disc (not shown in the figure), the second cable portion passes through the interior of the third drive member 1211, and the second cable portion is wound around the second winding disc. The second winding disc can rotate relative to the third drive member 1211 to release part of the second cable, or to wind more of the second cable onto the second winding disc. Thus, when the third drive member 1211 drives the third clamp 1210 to move relative to the housing 10, the second cable can move with the third drive member 1211, thereby avoiding the second cable from getting tangled in other structures included in the automation device 1, which could cause the second cable to be pulled or even damaged or broken. The arrangement of the second cable can be found in [reference needed]. Figure 8 The arrangement of the first cable 1203 shown in the figure, and the arrangement of the second cable and the second winding reel can be found in [reference needed]. Figure 9 The arrangement of the first cable 1203 and the first winding reel 1204 is shown in the figure.
[0104] It is understood that the second clamping assembly 120 and the third clamping assembly 121 can each select their structure according to their own usage requirements. In other words, the structures of the second clamping assembly 120 and the third clamping assembly 121 can be the same or different, and the structures of the second clamping assembly 120 and the third clamping assembly 121 can be referred to in the aforementioned various different embodiments.
[0105] 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 2 or automatically open to release the positive electrode 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.
[0106] like Figure 12 and Figure 13As shown, in order to improve the automation level of the pulse discharge process of the positive electrode 2 using the automation device 1, the automation device 1 can also realize the automatic unloading function of the positive current collector segment 200 after the pulse discharge process. Optionally, the automation device 1 further includes a receiving structure 13, which may include, but is not limited to, a receiving tray, a receiving box, etc. The receiving structure 13 is located on one side of the box body 10. The second clamping component 120 or the third clamping component 121 can respectively clamp the positive current collector segment 200 through the opening 101 and release the positive current collector segment 200. Alternatively, the second clamping component 120 and the third clamping component 121 can simultaneously clamp the positive current collector segment 200 through the opening 101 and release the positive current collector segment 200 sequentially or simultaneously, so that the positive current collector segment 200 falls into the receiving structure 13, thereby realizing the movement of the positive current collector segment 200 to the receiving structure 13 to realize the automatic unloading and recycling of the positive current collector segment 200.
[0107] Optionally, the receiving structure 13 and the cutting and feeding mechanism 11 are respectively located on both sides of the box 10. In other words, the receiving structure 13 and the cutting and feeding mechanism 11 are respectively located on two different sides of the box 10, so that the feeding and unloading functions of the automated device 1 are separated, the receiving structure 13 and the cutting and feeding mechanism 11 are less likely to interfere with each other, and the structure of the automated device 1 is more reasonable.
[0108] Please combine Figure 15 and Figure 16 As shown, when the second clamping assembly 120 includes a second chuck 1201 and a second drive member 1202, and the third clamping assembly 121 includes a third chuck 1210 and a third drive member 1211, for example, the second chuck 1201 can be rotatable relative to the second drive member 1202, and the third chuck 1210 can be rotatable relative to the third drive member 1211. This allows the second drive member 1202 and the third drive member 1211 to drive the second chuck 1201 and the third chuck 1210 to move, thereby moving the positive current collector segment. The positive manifold segment 200 is lifted above the opening 101. Then, by rotating the second chuck 1201 relative to the second drive member 1202, the third chuck 1210 is rotated relative to the third drive member 1211, thus transporting the positive manifold segment 200 above the receiving structure 13. Then, the second chuck 1201 and the third chuck 1210 simultaneously release the positive manifold segment 200, or the second chuck 1201 and the third chuck 1210 release the positive manifold segment 200 sequentially, allowing the positive manifold segment 200 to fall onto the receiving structure 13. (Note: This is for ease of observation.) Figure 15 Lieutenant General Figure 14 The sectional view obtained along the CC direction is adjusted so that the opening 101 of the box 10 faces upwards in the image. It should be noted that... Figure 16 The third clamp 1210 is blocked by the second clamp 1201.
[0109] Optionally, the automation device 1 may also include a detector 15 and a lifting mechanism 130. The detector 15 is located on the side of the housing 10 near the receiving structure 13. The lifting mechanism 130 supports the receiving structure 13 and is electrically connected to the detector 15. When the detector 15 detects that the actual relative height between the positive fluid collector segment 200 carried by the receiving structure 13 and the housing 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 fluid collector segment 200 on the receiving structure 13 is smaller, thereby making the posture of each positive fluid collector segment 200 on the receiving structure 13 more consistent, so that multiple positive fluid collector segments 200 are stacked more neatly on the receiving structure 13.
[0110] Optionally, the detector 15 may include, but is not limited to, a distance detector 15 and an image acquisition device. The detector 15 may be disposed on the outer periphery of the housing 10, so as to make the relative height between the detector 15 and the housing 10 fixed, so as to detect the actual relative height between the positive fluid collection section 200 carried by the housing structure 13 and the housing 10 through the detector 15.
[0111] For example, the detector 15 may include a distance detector 15. In this case, when the actual relative height between the positive fluid collector section 200 carried by the housing structure 13 and the housing 10 is lower than the height of the detector 15, the distance of the nearest object detected by the detector 15 is greater than a distance threshold. When the actual relative height between the positive fluid collector section 200 carried by the housing structure 13 and the housing 10 is equal to or higher than the height of the detector 15, the distance of the nearest object detected by the detector 15 is less than the distance threshold.
[0112] Optionally, when the detector 15 detects that the relative height between the positive fluid collector segment 200 carried by the housing structure 13 and the box 10 exceeds a predetermined height, the lifting mechanism 130 can lower the housing structure 13 by a predetermined height. In other words, each time the detector 15 detects that the relative height between the positive fluid collector segment 200 carried by the housing structure 13 and the box 10 exceeds a predetermined height, the lifting mechanism 130 is only set to lower the housing structure 13 by the same height, thereby improving the controllability of the drop distance range of each positive fluid collector segment 200 falling onto the housing structure 13.
[0113] Optionally, the control chip described in the foregoing 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 the predetermined height, the control chip can be used to drive the lifting mechanism 130 to lower the housing structure 13.
[0114] Please see again Figure 1 as well as Figure 3Alternatively, 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 located on one side of the box 10. The conveyor belt assembly 14 has a first end 140 and a second end 141 opposite to each other. The first end 140 is located at the bottom 100a corresponding to the second clamping assembly 120 and the third clamping assembly 121. The second end 141 is located corresponding to the receiving structure 13. The first end 140 of the conveyor belt assembly 14 can receive the positive flow section 200 falling from the second clamping assembly 120 and the third clamping assembly 121. The conveyor belt assembly 14 can transport the positive flow section 200 to the receiving structure 13. For example, the conveyor belt assembly 14 can transport the positive flow section 200 from the first end 140 to the second end 141 and can cause the positive flow section 200 to fall from the second end 141 to the receiving structure 13.
[0115] Optionally, the receiving structure 13 and the cutting and feeding mechanism 11 are respectively located on both sides of the box 10. In other words, the receiving structure 13 and the cutting and feeding mechanism 11 are respectively located on two different sides of the box 10, so that the feeding and unloading functions of the automated device 1 are separated, the receiving structure 13 and the cutting and feeding mechanism 11 are less likely to interfere with each other, and the structure of the automated device 1 is more reasonable.
[0116] Please combine Figure 10 and Figure 11 As shown, exemplarily, the conveyor belt assembly 14 includes a support 142, a plurality of rollers 143, a fifth drive member (not shown), and a belt body 144. The support 142 has a first end 140 and a second end 141. The plurality of rollers 143 are spaced apart on the support 142, and both the first end 140 and the second end 141 are provided with rollers 143. The fifth drive member can drive at least one roller 143 to rotate. The belt body 144 is integrally arranged around the support 142 and the plurality of rollers 143, and the rollers 143 can drive the belt body 144 to move, so that the positive current collector segment 200 falling 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 current collector segment 200 can fall from the second end 141 onto the receiving structure 13.
[0117] Optionally, the roller 143 may be tightly connected to the belt 144 so that the roller 143 drives the belt 144 to move through the friction between the roller 143 and the belt 144. Alternatively, the roller 143 may include a gear-like structure and the belt 144 may include a rack-like structure, so that the roller 143 and the belt 144 may be separably connected through a gear-and-rack-like structure so that the roller 143 can drive the belt 144 to move.
[0118] Optionally, when the conveyor belt assembly 14 includes a plurality of rollers 143, two of the rollers 143 may be the same or different, such as Figure 10 As shown, Figure 10 The diagram exemplarily shows a conveyor belt assembly 14 including three rollers 143, one of which is tightly connected to the belt body 144, and the other two rollers 143 are gear-like structures.
[0119] Optionally, the belt 144 has a first concave-convex structure 142a on the side facing the support 142, and at least the first end 140 of the support 142 has a second concave-convex structure 144a corresponding to the first concave-convex structure 142a. The first concave-convex structure 142a and the second concave-convex structure 144a are movably abutting each other. Thus, when the roller 143 drives the belt 144 to move around the belt 144 and the support 142 as a whole, the movable abutment of the first concave-convex structure 142a and the second concave-convex structure 144a allows at least a portion of the belt 144 corresponding to the first concave-convex structure 142a to vibrate closer to or further away from the support 142. This causes the positive current collector section 200 located at at least the first end 140 to vibrate in the cooling liquid, thereby dispersing the positive electrode material attached to the surface of the positive current collector section 200 into the cooling liquid, thus improving the separation and recovery efficiency of the electrode segment 20 when using the automated device 1 to separate and recover materials.
[0120] When the belt body 144 includes a rack-like structure as described in the aforementioned technical solution, the second concave-convex structure 144a can be formed as the rack-like structure, thereby enabling the second concave-convex structure 144a to be reused, making the structure of the conveyor belt assembly 14 more compact.
[0121] As described in the aforementioned technical solution, the roller 143 can be tightly connected to the belt 144 so that the roller 143 drives the belt 144 to move through the friction between the roller 143 and the belt 144. The outer periphery of the roller 143 can be provided with a relief groove 143a corresponding to the second concave-convex structure 144a, so as to avoid the second concave-convex structure 144a from affecting the tight connection between the roller 143 and the belt 144, thereby avoiding the failure of the driving effect of the roller 143 on the belt 144 due to the second concave-convex structure 144a.
[0122] Optionally, the belt 144 may also be provided with a plurality of spaced baffles 144b, so as to limit the position of the positive current collector segment 200 falling onto the belt 144 located at the first end 140, thereby improving the reliability of the process of transporting the positive current collector segment 200 to the receiving structure 13 via the belt 144.
[0123] Optionally, the automation device 1 may also include a detector 15 and a lifting mechanism 130. In this case, the configuration and corresponding effects of the detector 15 and the lifting mechanism 130 can be found in the aforementioned technical solution and will not be repeated here.
[0124] like Figures 3 to 6 as well as Figure 17 As shown, this application also provides a method for processing the positive electrode 2 by pulse discharge, which can use the automated device 1 provided in the aforementioned technical solution to perform pulse discharge processing on the positive electrode 2 with a high degree of automation, so as to perform pulse discharge processing on the positive electrode 2 with high efficiency. The processing method includes the following steps:
[0125] Step S1: The first driving member 110 drives the rotating shaft 111 to rotate, so that a first chuck 112a clamps part of the positive electrode 2 and rotates it to be close to the opening 101, and the end 2a of the positive electrode 2 is located on the side of the first chuck 112a that is close to the opening 101.
[0126] Step S2: The second clamping assembly 120 moves relative to the housing 10 to clamp the end 2a of the positive electrode 2;
[0127] Step S3: A first clamp 112a releases the positive electrode plate 2;
[0128] Step S4: The second clamping assembly 120 moves relative to the housing 10 so that the end 2a of the positive electrode 2 enters the cavity 100. The first driving member 110 synchronously drives the rotating shaft 111 to rotate so that another first clamp 112a clamps another part of the positive electrode 2 and rotates it to be close to the opening 101.
[0129] Step S5: The third clamping assembly 121 moves relative to the housing 10 to clamp the positive electrode 2 located on the side of another first clamp 112a near the opening 101.
[0130] Step S6: The cutting component 113 cuts the positive electrode sheet 2 located between another first clamp 112a and the third clamping assembly 121 to obtain an 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.
[0131] Optionally, after step S5 and before step S6, the processing method further includes:
[0132] Step S5a: The third clamping assembly 121 moves away from the other first clamp 112a to tighten the positive electrode 2 located between the other first clamp 112a and the third clamping assembly 121.
[0133] This allows the cutting component 113 to cut the positive electrode sheet 2 located between another first chuck 112a and the third clamping assembly 121, and improves the reliability of the cutting process of the positive electrode sheet 2 by the cutting component 113.
[0134] Step S7: The third clamping assembly 121 moves relative to the housing 10 so that the entire pole segment 20 enters the cavity 100;
[0135] Step S8: Power on the second clamping assembly 120 and the third clamping assembly 121 so that the pulse current flows to the electrode segment 20. The positive electrode material included in the electrode segment 20 is separated from the positive current collector segment 200. The two ends of the positive current collector segment 200 are clamped by the second clamping assembly 120 and the third clamping assembly 121, respectively.
[0136] Step S9: Recover the positive current collector section 200.
[0137] Please combine Figure 15 and Figure 16 As shown, when the automation device 1 further includes a housing structure 13 as described in the foregoing technical solution, optionally, step S9 further includes:
[0138] 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 section 200 is disengaged from the cavity 100 through the opening 101 and corresponds to the receiving structure 13;
[0139] In step S91, both the second clamping assembly 120 and the third clamping assembly 121 release the positive current collector section 200, causing the positive current collector section 200 to fall onto the receiving structure 13.
[0140] Please combine Figure 10 and Figure 11 As shown, when the automation device 1 further includes a housing structure 13 and a conveyor belt assembly 14 as described in the foregoing technical solution, alternatively, step S9 further includes:
[0141] In step S90', both the second clamping assembly 120 and the third clamping assembly 121 release the positive collector section 200, causing the positive collector section 200 to fall onto the conveyor belt assembly 14.
[0142] Step S91': Conveyor belt assembly 14 transports positive current collector section 200 from inside cavity 100 to outside cavity 100;
[0143] In step S92', the conveyor belt assembly 14 continues to transport the positive fluid collector segment 200 until the positive fluid collector segment 200 falls from the end of the conveyor belt assembly 14 away from the cavity 100 onto the receiving structure 13.
[0144] When, as described in the foregoing technical solution, the automated device 1 may further include a detector 15 and a lifting mechanism 130, the processing method after step S9 further includes:
[0145] Step S9a: Detector 15 detects the actual relative height between the positive current collector section 200 carried by the housing structure 13 and the box 10.
[0146] If the actual relative height is greater than the predetermined height, then step S9b is executed to cause the lifting mechanism 130 to drive the housing structure 13 to descend.
[0147] As a result, the difference in the falling distance of each positive fluid collector segment 200 onto the housing structure 13 is small, which makes the posture of each positive fluid collector segment 200 on the housing structure 13 more consistent, so that multiple positive fluid collector segments 200 can be stacked more neatly on the housing structure 13.
