DETAILED DESCRIPTION

[0052] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0053] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0055] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] Reference Figures 1 to 17 The embodiment of the present application provides an integrated processing device for pole pieces, which can process unqualified pole pieces produced in the production process, and can also process pole pieces scrapped after use, and the integrated processing device includes:

[0058] Base 1, feeding assembly 2, cutting assembly 3, sorting assembly 4 and cleaning assembly 5, see Figures 1 to 4 The base 1 is provided with a feeding station, a cutting station, a sorting station and a cleaning station, that is, the integrated processing device provided in the embodiment of the present application integrates the feeding, cutting, sorting and cleaning of the electrode into one processing device to improve the diversity and processing efficiency of the electrode processing by the integrated processing device described in the present application.

[0059] See also Figure 1 and Figure 2 The feeding component 2, the cutting component 3, the sorting component 4 and the cleaning component 5 are respectively arranged on the feeding station, the cutting station, the sorting station and the cleaning station. For example, the feeding component 2, the cutting component 3, the sorting component 4 and the cleaning component 5 can be respectively arranged on the feeding station, the cutting station, the sorting station and the cleaning station around the base 1, so that the feeding component 2, the cutting component 3, the sorting component 4 and the cleaning component 5 are integrally connected to the base 1.

[0060] The feeding component 2 is used to transfer the electrode between the feeding station and the external feeding mechanism. Specifically, a loading area and a discharging area can be set on the feeding component 2. The feeding component 2 can transfer the unprocessed electrode on the external feeding mechanism such as the conveyor belt to the loading area, and can also transfer the processed electrode from the discharging area to the external feeding mechanism.

[0061] The cutting assembly 3 is used to cut the pole pieces, for example, to cut a large-sized pole piece into a plurality of small pole pieces of the same or different sizes, or to cut a plurality of large-sized pole pieces into a plurality of small-sized pole pieces at the same time, and to die-cut pole ears on the pole pieces while cutting the pole pieces, so as to facilitate the assembly of the pole pieces into the pole core of the battery.

[0062] The sorting component 4 is used to sort the cut pole pieces. For example, unqualified pole pieces produced during the production process may have problems such as pole piece breakdown, uneven coating of the active layer on the pole piece, or partial loss of the active layer on the pole piece. The sorting component 4 can select pole pieces that meet the recycling standards according to the recycling standards to achieve accurate processing and recycling of the pole pieces.

[0063] The cleaning assembly 5 is used to clean the tabs on the pole pieces that meet the recycling standards. Specifically, during the cutting process, the tabs can be die-cut on the pole pieces at the same time, and at this time, the tabs may be coated with an active layer, or when the pole pieces originally have tabs, there may be impurities such as active substances or electrolyte residues on the tabs. In order to ensure the electrical transmission stability of the tabs and the strength of the connection between the tabs, the tabs on the pole pieces that meet the recycling standards can be cleaned by the cleaning assembly 5, so as to obtain complete and clean tabs by exposing the current collector at the tabs.

[0064] The integrated processing device provided in the embodiment of the present application includes a base 1, a material feeding component 2, a cutting component 3, a sorting component 4 and a cleaning component 5. The base 1 is provided with a material feeding station, a cutting station, a sorting station and a cleaning station. The material feeding component 2, the cutting component 3, the sorting component 4 and the cleaning component 5 are respectively arranged on the material feeding station, the cutting station, the sorting station and the cleaning station, that is, the conveying, cutting, sorting and cleaning of the electrode are integrated into one of the integrated processing device, which can improve the electrode processing efficiency of the integrated processing device while reducing the volume of the integrated processing device.

[0065] Moreover, through the integrated processing of conveying, cutting, sorting and cleaning, the process flow of electrode processing is simplified, the operation time of the electrode processing process is reduced, and it can meet the processing needs of most sizes of electrodes.

[0066] Alternatively, see Figure 4 The integrated processing device also includes a rotating component 6, which is rotatably connected to the base 1. A tray 7 is provided on the rotating component 6, and the tray 7 is used to carry the electrode pieces. The rotating component 6 is used to transfer the tray 7 containing the electrode pieces between the feeding station where the feeding component 2 is located, the cutting station where the cutting component 3 is located, the sorting station where the sorting component 4 is located, and the cleaning station where the cleaning component 5 is located.

[0067] Specifically, the integrated processing device provided in the embodiment of the present application needs to transfer the electrode to the next process after one process is completed during the process of carrying out the electrode sheet through the conveying process, cutting process, sorting process and cleaning process. For example, after the cutting component 3 cuts the electrode sheet, it is necessary to transfer the cut electrode sheet from the cutting station to the sorting station where the sorting component 4 is located. Four trays 7 can be connected to the rotating component 6, and the four trays 7 are respectively located at the feeding station, the cutting station, the sorting station and the cleaning station. The cutting component 3 can cut the electrode sheet on the tray 7 located at the cutting station, and after cutting the electrode sheet, the tray 7 located at the cutting station and the electrode sheet on the tray 7 can be transferred to the sorting station together through the rotation of the rotating component 6, so that the sorting component 4 can sort the cut electrode sheet, thereby improving the processing efficiency of the electrode sheet by the integrated processing device.

[0068] In addition, the conversion of the pole piece between the feeding station where the feeding component 2 is located, the cutting station where the cutting component 3 is located, the sorting station where the sorting component 4 is located, and the cleaning station where the cleaning component 5 is located can also be completed by a robot.

[0069] Alternatively, see Figures 1 to 3 The feeding assembly 2, the cutting assembly 3, the sorting assembly 4 and the cleaning assembly 5 are sequentially arranged on the circumference of the base 1, and the rotating assembly 6 is used to move the tray 7 through the feeding assembly 2, the cutting assembly 3, the sorting assembly 4 and the cleaning assembly 5 in sequence.

[0070] Specifically, the feeding station, cutting station, sorting station and cleaning station arranged on the base 1 can be respectively located in the circumference of the base 1, so that the feeding assembly 2, cutting assembly 3, sorting assembly 4 and cleaning assembly 5 are respectively arranged on the feeding station, cutting station, sorting station and cleaning station around the base 1, and the feeding assembly 2, cutting assembly 3, sorting assembly 4 and cleaning assembly 5 can be integrally connected to the base 1. The cutting assembly 3 is used to cut the electrode piece transferred from the feeding station to the cutting station, the sorting assembly 4 is used to sort the electrode piece transferred from the cutting station to the sorting station after cutting, and the cleaning assembly 5 is used to clean the pole ears on the electrode piece that meets the recycling standard and is transferred from the sorting station to the cleaning station.

[0071] The feeding component 2, cutting component 3, sorting component 4 and cleaning component 5 on the circumference of the base 1 can continuously process the electrode pieces. For example, the feeding component 2, cutting component 3, sorting component 4 and cleaning component 5 can process different electrode pieces at the same time. Moreover, since the feeding component 2, cutting component 3, sorting component 4 and cleaning component 5 are respectively arranged on the four sides of the base 1, the integrated processing device can form a ring-shaped processing for the electrode pieces. On the basis of ensuring the processing efficiency of the integrated processing device for the electrode pieces, the compactness of the integrated processing device is improved and the space occupied by the integrated processing device is reduced.

[0072] Specifically, see Figure 4 The base 1 may include a substrate 11, for example, the substrate 11 may be a square substrate, and the feeding component 2, the cutting component 3, the sorting component 4 and the cleaning component 5 are respectively distributed around the substrate 11. When the feeding station, the cutting station, the sorting station and the cleaning station around the substrate 11 process different electrodes, mutual interference between the electrodes at different stations can be avoided, thereby improving the processing efficiency of the electrode by the integrated processing device.

[0073] Alternatively, see Figure 4 The base 1 further comprises a fixed column 12, the fixed column 12 is connected to the base plate 11, and the rotating assembly 6 is sleeved on the fixed column 12. The rotating assembly 6 can flexibly rotate on the fixed column 12, so that the rotating assembly 6 can flexibly switch the tray 7 containing the electrode sheets between the feeding station where the feeding assembly 2 is located, the cutting station where the cutting assembly 3 is located, the sorting station where the sorting assembly 4 is located, and the cleaning station where the cleaning assembly 5 is located.

[0074] Specifically, see Figure 4 The fixing column 12 includes a first fixing section 121 and a second fixing section 122 connected in sequence, the first fixing section 121 is located between the base plate 11 and the second fixing section 122, and the circumferential dimension of the first fixing section 121 is greater than the circumferential dimension of the second fixing section 122;

[0075] The rotating component 6 is sleeved on the second fixing section 122 so that the rotating component 6 is suspended on the substrate 11 .

[0076] Specifically, the fixed column 12 can form a stepped cylindrical structure. Since the circumferential dimension of the first fixed section 121 is larger than the circumferential dimension of the second fixed section 122, the rotating assembly 6 can be mounted on the step of the fixed column 12 when it is sleeved on the second fixed section 122, so that the rotating assembly 6 is suspended on the substrate 11. The processing positions of the feeding assembly 2, the cutting assembly 3, the sorting assembly 4 and the cleaning assembly 5 can be higher than the substrate 11. The suspended setting of the rotating assembly 6 can deliver the tray 7 containing the electrode pieces to the processing positions of the feeding assembly 2, the cutting assembly 3, the sorting assembly 4 and the cleaning assembly 5, so as to ensure the position accuracy of the electrode pieces processed by the integrated processing device.

[0077] Also, see Figures 1 to 4 The feeding component 2 can be connected to an end of the second fixed section 122 away from the first fixed section 121, and the cutting component 3, the sorting component 4 and the cleaning component 5 can be respectively connected to one side of the substrate 11.

[0078] Alternatively, see Figure 5 and Figure 6 The feeding assembly 2 includes a moving mechanism 21 and an adsorption portion 22 connected to the moving mechanism 21. The adsorption portion 22 is used to adsorb the electrode pieces in the tray 7 and transfer the electrode pieces between the feeding station and the external feeding mechanism through the moving mechanism 21.

[0079] Specifically, when the feeding assembly 2 transfers the electrode piece between the feeding station and the external feeding mechanism, the adsorption part 22 can be moved by the moving mechanism 21. When the adsorption part 22 moves to the external feeding mechanism, the electrode piece can be sucked by the adsorption part 22, and then the adsorption part 22 and the electrode piece are transferred to the feeding station together by the moving mechanism 21. At this time, the adsorption part 22 can release the electrode piece to facilitate the transfer of the electrode piece to the subsequent processing station. The moving mechanism 21 can be flexibly moved in two or more directions. The setting of the moving mechanism 21 can make the adsorption part 22 move in two or more directions, which improves the flexibility of the adsorption part 22 to grab and release the electrode piece; and the adsorption part 22 can vacuum adsorb the electrode piece, which can simplify the connection of the electrode piece transfer process, that is, reduce the use of mechanical connection components for the electrode piece, and also reduce the degree of mechanical damage to the electrode piece, ensuring the integrity of the electrode piece during the transfer process.

[0080] Alternatively, see Figure 1 , Figure 6 and Figure 7The moving mechanism 21 includes an air pump 211, a first pneumatic shaft 212, a second pneumatic shaft 213 and an adapter plate 214. The air pump 211 is arranged on the base 1. One end of the first pneumatic shaft 212 is connected to the air pump 211. The other end of the first pneumatic shaft 212 is telescopically connected to the adapter plate 214 along a first direction. One end of the second pneumatic shaft 213 is telescopically connected to the adapter plate 214 along a second direction. The other end of the second pneumatic shaft 213 is connected to the adsorption portion 22. An angle is formed between the first direction and the second direction.

[0081] Specifically, the structure of the moving mechanism 21 can be that two first pneumatic shafts 212 extend from one side of the air pump 211, and the first pneumatic shafts 212 can be set to be telescopic in the horizontal direction to control the position of the adapter plate 214 in the horizontal direction, and two second pneumatic shafts 213 can be connected to the adapter plate 214, and the second pneumatic shafts 213 can be set to be telescopic in the vertical direction and connected to the adsorption part 22, so as to realize the free movement of the adsorption part 22 in two dimensions in the horizontal front-back direction and the vertical up-down direction. That is, at this time, the first direction and the second direction are perpendicular to each other, and in addition, the first direction and the second direction can also be at an acute angle or an obtuse angle.

[0082] Furthermore, the first pneumatic shaft 212 and the second pneumatic shaft 213 are connected to the air pump control unit in the air pump 211 through air pipelines, and the air pump control unit controls the extension and contraction of the first pneumatic shaft 212 and the second pneumatic shaft 213. A plurality of vacuum suction nozzles can be attached under the adsorption part 22, so that the adsorption part 22 is attached to the surface of the adsorbed object such as the pole piece through the suction nozzle, and the pressure difference between the inside and outside of the suction nozzle is created by vacuuming to achieve adsorption of the pole piece and other objects, and then the pole piece is driven to move through the moving mechanism 21.

[0083] The specific process of the feeding component 2 transferring the electrode between the feeding station and the external feeding mechanism is as follows: Figure 7 As shown, including:

[0084] like Figure 7 During the process from (1) to (2), the second pneumatic shaft 213 is extended, so that the adsorption part 22 falls into the tray 7, and the adsorption part 22 is attached to the surface of the last group of processed electrodes through the vacuum suction nozzle;

[0085] like Figure 7 During the process (2)-(3), the vacuum pump of the air pump 211 is started, the adsorption part 22 sucks up the processed electrode piece in the tray, and the second pneumatic shaft 213 contracts, so that the adsorption part 22 and the processed electrode piece are lifted and separated from the tray 7;

[0086] like Figure 7During the process of (3)-(4), the first pneumatic shaft 212 is extended, and the adsorption part 22 and the processed electrode piece are moved to above the discharge conveyor belt of the external feeding mechanism;

[0087] like Figure 7 During the process of (4)-(5), the second pneumatic shaft 213 is extended, and the adsorption part 22 and the processed electrode piece fall onto the discharge conveyor belt;

[0088] like Figure 7 During the process of (5)-(6), the vacuum pump of the air pump 211 is turned off, the adsorption effect of the adsorption part 22 on the electrode piece disappears, the processed electrode piece falls onto the discharge conveyor belt, and the second pneumatic shaft 213 contracts to lift the adsorption part 22;

[0089] like Figure 7 During the process of (6)-(7), the first pneumatic shaft 212 contracts and the adsorption part 22 moves to above the infeed conveyor belt;

[0090] like Figure 7 During the process of (7)-(8), the second pneumatic shaft 213 is extended, and the adsorption part 22 falls onto the infeed conveyor belt;

[0091] like Figure 7 During the process of (8)-(9), the vacuum pump of the air pump 211 is started, the adsorption part 22 sucks up the electrode piece to be processed on the feeding conveyor belt, the second pneumatic shaft 213 contracts, and the adsorption part 22 and the electrode piece to be processed are lifted;

[0092] like Figure 7 During the process of (9)-(10), the first pneumatic shaft 212 continues to contract, and the adsorption portion 22 and the electrode to be processed move together to the top of the tray 7;

[0093] like Figure 7 During the process of (10)-(11), the second pneumatic shaft 213 is extended, and the adsorption part 22 and the electrode to be processed fall onto the tray 7;

[0094] like Figure 7 During the process from (11) to (12), the vacuum pump of the air pump 211 is turned off, the adsorption effect of the adsorption part 22 on the electrode piece disappears, the electrode piece to be processed falls onto the tray 7, the second pneumatic shaft 213 contracts, and the adsorption part 22 is lifted and reset.

[0095] The above can realize a process of feeding in the electrode to be processed and discharging the processed electrode, and the cyclic processing of the electrode can be completed by repeating the above process.

[0096] Alternatively, see Figure 8 and Fig. 9The cutting assembly 3 includes a tool structure 31 and a tool groove structure 32. When the pole piece is in the cutting station, the tool structure 31 and the tool groove structure 32 are relatively arranged on both sides of the pole piece.

[0097] Specifically, when the pole piece is transferred from the feeding station to the cutting station, the cooperation of the tool structure 31 and the knife groove structure 32 can realize the cutting of the pole piece. For example, the tool structure 31 and the knife groove structure 32 can be relatively arranged on both sides of the pole piece and can be far away from and close to the pole piece. When the tool structure 31 and the knife groove structure 32 are close to the pole piece together, the tool structure 31 and the knife groove structure 32 can simultaneously abut against both sides of the pole piece and fix the pole piece. When the tool structure 31 and the knife groove structure 32 continue to approach, the pole piece can be cut by the tool structure 31 and then inserted into the knife groove structure 32. The cutting of the pole piece is realized on the basis of ensuring the stability of the position of the pole piece. The accuracy of cutting the pole piece can be improved by the cooperation of the tool structure 31 and the knife groove structure 32.

[0098] Alternatively, see Fig. 9 and Fig.10 The tool structure 31 includes a third pneumatic shaft 311 and a tool 312. The third pneumatic shaft 311 is telescopically connected to the tool 312 so that the tool 312 is close to or away from the tool groove structure 32. The tool groove structure 32 includes a fourth pneumatic shaft 321 and a tool groove 322. The fourth pneumatic shaft 321 is telescopically connected to the tool groove 322 so that the tool groove 322 is close to or away from the tool structure 31.

[0099] Specifically, the third pneumatic shaft 311 and the fourth pneumatic shaft 321 can be connected to the air pump 211 through an air pipe, that is, the extension and retraction of the third pneumatic shaft 311 and the fourth pneumatic shaft 321 can be controlled by the air pump 211. When the pole piece to be cut is located between the tool structure 31 and the knife groove structure 32, the third pneumatic shaft 311 can be used to make the tool 312 close to the pole piece, and the fourth pneumatic shaft 321 can be used to make the knife groove 322 close to the pole piece and make the tool 312 and the knife groove 322 clamp the pole piece, so as to achieve accurate cutting of the pole piece on the basis of ensuring the stability of the position of the pole piece.

[0100] See also Figure 2 The pole piece to be cut rotates 90° clockwise along with the tray 7 under the rotation of the rotating assembly 6, so that the tray 7 and the pole piece to be cut enter the cutting station together.

[0101] like Fig.10 As shown, Fig.10 The electrode in (1) is located at the cutting station. Fig.10(2) The tool 312 and the tool groove 322 approach the pole piece and cut the pole piece. Fig.10 In (3), the tool 312 and the tool groove 322 are away from the pole piece and realize the reset of the cutting component 3.

[0102] Alternatively, see Fig. 9 and Fig.10 The tool 312 includes an integrally formed pole piece cutting tool and a pole ear die cutting tool.

[0103] Specifically, when the cutting assembly 3 is cutting the pole piece, it can cut the large-sized pole piece into multiple small-sized pole pieces and die-cut the pole lug. The pole piece cutting tool and the pole lug die-cutting tool of the tool 312 can simultaneously complete the slitting of the pole piece and the die-cutting of the pole lug, which greatly improves the cutting process efficiency and reduces the cutting process time.

[0104] In addition, the cutting of the tabs can be performed by die-cutting the tabs on the pole pieces while cutting the pole pieces, or by cutting the edge of the existing tabs to facilitate the cleaning and connection of the tabs at a later stage.

[0105] Alternatively, see Fig.11 and Fig.12 , the sorting component 4 includes a scanning device 41 and a storage box 42;

[0106] When the pole pieces in the tray 7 are at the sorting station, the tray 7 is located on the storage box 42, and the scanning device 41 is used to scan the pole pieces to select the pole pieces that meet the recycling standards.

[0107] See also Figures 11 to 13 , the electrode pieces to be sorted after cutting rotate 90° clockwise with the tray 7 under the rotation of the rotating assembly 6, so that the tray 7 and the electrode pieces to be cut enter the sorting station together. The scanning device 41 can be externally connected to the storage box 42. The scanning device 41 can be a scanning device such as a CCD sensor system, an ultrasonic detection device or a laser detection device. After the scanning device 41 scans the electrode pieces, the electrode pieces that meet the recycling standards can be transferred to the cleaning station, and the electrode pieces that do not meet the recycling standards can be recycled into the storage box 42. On the basis of accurately classifying the electrode pieces, the efficiency of the integrated processing device in recycling the electrode pieces can be guaranteed.

[0108] Alternatively, see Fig.12 and Fig.13 The tray 7 is provided with a movable bottom plate 71 . When the electrode piece does not meet the recycling standard, the movable bottom plate 71 is pulled away from the tray 7 to allow the electrode piece to fall into the storage box 42 .

[0109] Specifically, the movable bottom plate 71 on the tray 7 can realize the classification of the electrodes. Specifically, when the electrodes on the tray 7 meet the recycling standards, the movable bottom plate 71 can be retained on the tray 7, and the electrodes that meet the recycling standards can be transferred to the cleaning station; and when the electrodes on the tray 7 do not meet the recycling standards, the movable bottom plate 71 can be pulled away from the tray 7 so that the electrodes fall into the storage box 42. Fig.13 The process before and after electrode sorting is given to ensure effective classification during electrode processing.

[0110] Alternatively, see Figures 14 to 16 , the cleaning assembly 5 includes a cleaning box 51 and a cleaning probe 52 located inside the cleaning box 51;

[0111] When the pole piece is in the cleaning station, the cleaning probe 52 is used to clean the pole lug of the pole piece.

[0112] See also Figure 2 After sorting, the pole pieces to be cleaned rotate 90° clockwise with the tray 7 under the rotation of the rotating assembly 6, so that the tray 7 and the pole pieces to be cleaned enter the cleaning station together. The pole pieces located at the cleaning station can be aligned with the position of the pole ears on the pole pieces by the cleaning probe 52, and the cleaning probe 52 cleans the active layer on the pole ears by a laser with set parameters, for example, the set parameters can be 250W, and the wavelength is 1064nm. After the cleaning probe 52 cleans the pole ears on the pole pieces, the cleaned pole pieces located in the cleaning box 51 can be transferred to the feeding assembly 2 through the rotating assembly 6, and the feeding assembly 2 generally transports the cleaned pole pieces to the external feeding mechanism.

[0113] In addition, the cleaning probe 52 may also be replaced by a cleaning probe such as a plasma cleaning probe or an ultrasonic cleaning probe, which can also ensure the cleaning effect of the pole tab on the pole piece.

[0114] Alternatively, see Fig.15 , the cleaning probe 52 includes a first cleaning probe and a second cleaning probe that are arranged opposite to each other;

[0115] When the pole piece is in the cleaning station, the first cleaning probe and the second cleaning probe are arranged oppositely on two sides of the pole ear of the pole piece.

[0116] Specifically, the pole piece located in the cleaning station can be coated with an active layer on both sides to improve the energy density of the battery cell formed by the pole piece. When cleaning the pole ear on the double-sided coated pole piece, there will also be active dressings on both sides of the pole ear. In order to improve the efficiency of cleaning the active dressings on the pole ear, a first cleaning probe and a second cleaning probe can be set relative to each other, and when the pole piece is in the cleaning station, the first cleaning probe and the second cleaning probe are relatively set on both sides of the pole ear of the pole piece, so that the first cleaning probe and the second cleaning probe can clean both sides of the pole ear of the pole piece at the same time, thereby improving the cleaning efficiency of the cleaning component 5.

[0117] Optionally, the pole pieces processed by the integrated processing device include a first pole piece, a second pole piece and a third pole piece;

[0118] When the cutting component 3 is used to cut the first pole piece, the sorting component 4 is used to sort the second pole piece, and the cleaning component 5 is used to clean the third pole piece.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
