Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of battery cell manufacturing, and in particular, to an electrode tab cleaning device. BACKGROUND

[0002] A power battery includes an electrode tab, a separator, a shell, and the like. A coating is applied to a specific area on both sides of a foil to form an electrode tab. In the production process of a power battery, when a large-size electrode tab coated with a coating is required to produce a small-size electrode tab, an operator first cuts a plurality of small electrode tabs from the area of the large electrode tab coated with the coating, and then removes the coating on the surface of the small electrode tab in the designated area by using some method to expose the small electrode tab to the required electrode tab.

[0003] In the related art, a laser is used to remove the coating on the surface of the designated area to expose the small electrode tab to the required electrode tab.

[0045] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0046] In the present disclosure, the orientation words such as "up, down, vertical" are defined according to the use direction of the tab cleaning device, and "inner, outer" are defined according to the contour of the corresponding parts. "Left, right" is defined according to the process of tab cleaning. It can be understood that, please combine Figure 1 , the pole piece needs to be loaded on the right side of the tab cleaning device, cleaned in the middle and unloaded on the left side. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, the following description relates to the drawings, and unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0047] Please refer to Figure 1 and Figure 2 , the tab cleaning device provided by the embodiment of the present disclosure can include a rack 10 and a clamp mechanism 30, a jaw opening mechanism 40, a cleaning mechanism 20 and a driving mechanism 50 respectively installed on the rack. These mechanisms can be fixedly installed with the rack 10 or can be relatively movably arranged on the rack 10.

[0048] The rack 10 can be formed with a feeding station 11, a discharging station 12 and a cleaning station 13. The clamp mechanism 30 can be installed on the rack 10 for clamping the pole piece 1. The clamp mechanism 30 can make the tab 2 of the pole piece 1 extend out of the clamp mechanism 30. The clamp mechanism 30 can clamp the main body part of the pole piece 1 to avoid the tab 2 part, so that the tab 2 can be completely immersed in the cleaning liquid for cleaning. The clamp jaw opening mechanism 40 can be used to open the clamp mechanism 30 before the clamp mechanism 30 clamps the pole piece 1 at the feeding station 11, that is, the clamp mechanism 30 is opened before feeding, so that the pole piece 1 can be fed into the clamp mechanism 30 and then clamped by the clamp mechanism 30. At the discharging station 12, the clamp jaw opening mechanism 40 can be used to loosen the clamping of the pole piece 1 by the clamp mechanism 30, so that the pole piece 1 can leave the clamp mechanism 30 and be discharged. The cleaning mechanism 20 can be provided at the cleaning station 13 for cleaning the tab 2. At the cleaning station 13, the clamp mechanism 30 can clamp the pole piece 1 and extend the tab 2 part into the cleaning liquid for cleaning. The specific cleaning liquid of the cleaning mechanism 20 can make the surface coating of the tab 2 fall off through physical or chemical reaction and ultrasonic vibration. The specific cleaning liquid can be solvent or hot water, etc. The driving mechanism 50 can be installed on the rack 10 and can be in transmission connection with the clamp mechanism 30. The driving mechanism 50 is used to drive the clamp mechanism 30 to move between the feeding station 11, the cleaning station 13 and the discharging station 12.

[0049] In the related art, when laser cleaning is used, the coating is instantaneously sublimated at high temperature, accompanied by combustion to generate powder. In the embodiment, the surface layer coating of the tab 2 region is soaked in water at a specific temperature, which drives the adhesive between the surface layer coating and the foil to melt, and then makes the surface layer coating of the tab 2 region fall off as a whole, avoiding the generation of dust during the removal of the coating of the tab 2. The temperature of the cleaning liquid is lower than that of the laser, so the cleaning mechanism 20 can not only clean the coating of the pole piece 1 to expose the tab 2, but also can ensure that the foil of the tab 2 is not oxidized, so the cleaning effect is good, and the welding quality of the tab 2 in ultrasonic welding is ensured. Moreover, the tab cleaning device of the embodiment can operate the whole feeding, discharging and cleaning process through various mechanisms installed on the rack 10, which improves the degree of automation, reduces the labor intensity of workers, and improves the cleaning efficiency of the tab 2.

[0050] In the embodiment, please refer to Figure 1 The feeding station 11 and the discharging station 12 are respectively located on both sides of the rack 10. Of course, in other embodiments, the feeding station 11 and the discharging station 12 can be located on the same side of the rack 10, that is, the feeding station 11 and the discharging station 12 are integrated into one station, and the clamp mechanism 30 can realize both feeding and discharging of the pole piece 1 at the station. The user can adjust the distribution of the feeding station 11 and the discharging station 12 according to the operation habit of the assembly line, which is not limited specifically here.

[0051] In an embodiment, referring to Figure 2 , Figure 3 , Figure 7 and Figure 9 , the tab cleaning device can include a rotating assembly 32, which can be used to drive the clamp mechanism 30 to rotate, so as to switch the clamp mechanism 30 between the feeding and discharging states. When the feeding station 11 and the discharging station 12 are located at the two sides of the rack 10 respectively, the number of the rotating assembly 32 can be one, two or more. When the rotating assembly 32 is one, the rotating assembly 32 needs to be installed on the driving mechanism 50 to realize that two stations share one rotating assembly 32. When the rotating assembly 32 is two, the two rotating assemblies 32 can be installed at the two sides of the rack 10 respectively to control the feeding and discharging of the clamp mechanism 30 respectively. The two rotating assemblies 32 are independent of each other and do not affect each other.

[0052] In an embodiment of the present disclosure, referring to Figure 2 , before the feeding and discharging of the pole piece 1, the rotating assembly 32 drives the clamp mechanism 30 to rotate to the horizontal state, so as to avoid that the pole piece 1 slides off from the clamp mechanism 30 before the clamp mechanism 30 clamps the pole piece 1 after the feeding of the pole piece 1, and ensure the clamping effect of the clamp mechanism 30. Referring to Figure 1 , before the cleaning of the pole piece 1, the rotating assembly 32 drives the clamp mechanism 30 to rotate to the vertical state, so as to ensure that the two side surfaces of the tab 2 can simultaneously extend into the cleaning liquid, and avoid that one surface of the tab 2 is not cleaned in place. The switching of the clamp mechanism 30 between the two states is realized by setting the rotating assembly 32.

[0053] In the present embodiment, referring to Figure 2 , Figure 7 and Figure 9 , the rotating assembly 32 can include a rotating shaft 3211, a transmission member 321 and a first power mechanism 322. The outer periphery of the rotating shaft 3211 can be formed with a stepped surface for mounting the clamp mechanism 30. The transmission member 321 can include a driving wheel 3212 and a rack 3213. The driving wheel 3212 can be sleeved on the rotating shaft 3211, the driving wheel 3212 can be a gear, and the rack 3213 can be in meshing connection with the driving wheel 3212. The first power mechanism 322 can be used to drive the driving wheel 3212 to rotate, so that the clamp mechanism 30 can be switched between the feeding and discharging states and the cleaning state. By this gear and rack 3213 transmission driving mode, the stability during rotation can be improved, and the control is simple.

[0054] Of course, in other embodiments, the transmission member 321 can also be a worm gear, a lead screw or the like mechanism. The driving mode of the rotating assembly 32 can also be that the motor directly drives the clamp mechanism 30 to rotate.

[0055] It can be understood that, please combine Figure 2 , Figure 7 and Figure 9 , when the pole piece 1 is in the feeding and discharging station, the first power mechanism 322 drives the rack 3213 to move towards the first power mechanism 322, and the movement of the rack 3213 can drive the gear to rotate the shaft 3211, so as to rotate the clamp mechanism 30 to the horizontal state. Please combine Figure 1 , Figure 7 and Figure 9 , when the pole piece 1 is in the cleaning station, the first power mechanism 322 drives the rack 3213 to move reversely, and the reverse movement of the rack 3213 can drive the gear to rotate the shaft 3211 reversely, so as to rotate the clamp mechanism 30 to the vertical state.

[0056] Further, please refer to Figure 7 and Figure 9 , the first power mechanism 322 can include a first cylinder 3222 and a connecting piece 3221, and the first cylinder 3222 can be in transmission connection with the connecting piece 3221. Wherein, the rotating assembly 32 can further include a fourth mounting seat 328 mounted on the rack 10, and the first cylinder 3222 can be mounted on the fourth mounting seat 328. One end of the rack 3213 can be provided with a connecting joint 326, and the connecting joint 326 can be provided with a connecting groove 3261 for plug connection with the connecting piece 3221, so as to drive the first cylinder 3222 and the rack 3213 in transmission connection after plug connection. Through the plug connection, the rotating assembly 32 and the clamp mechanism 30 can be separated, and the rotating assembly 32 does not need to move synchronously with the clamp mechanism 30 between various stations, so that the control structure is simplified.

[0057] It is not difficult to understand that, please combine Figure 1 , Figure 2 , Figure 7 and Figure 9 , before the clamp mechanism 30 needs to be rotated from the vertical state to the horizontal state (i.e. before feeding or discharging), the first cylinder 3222 first drives the connecting piece 3221 to extend, and then the driving mechanism 50 drives the clamp mechanism 30 to move laterally along the left-right direction, so that the connecting groove 3261 of the connecting joint 326 is located at the connecting piece 3221, and the two achieve lateral plug connection, and then the first cylinder 3222 drives the connecting piece 3221 to retreat, so as to rotate the clamp mechanism 30 to the horizontal state. After the pole piece 1 is fed or discharged, the first cylinder 3222 drives the connecting piece 3221 to advance, and the advancing of the connecting piece 3221 drives the rack 3213 to move, so as to drive the shaft 3211 to rotate the clamp mechanism 30 to the vertical state.

[0058] In other embodiments, an electric cylinder can be used to replace the pneumatic cylinder to ensure the stable overturning of the clamp mechanism 30.

[0059] In an embodiment, please refer to Figure 1 , Figure 5 and Figure 7 , the rotating assembly 32 can further comprise a connecting seat 323, the connecting seat 323 can be connected to the driving mechanism 50, the rotating shaft 3211 can be rotatably connected to the connecting seat 323, one of the connecting seat 323 and the clamp mechanism 30 can be provided with a first magnetic attraction member 325, and the other can be provided with a second magnetic attraction member 327, when the clamp mechanism 30 is rotated to the feeding or discharging state, the first magnetic attraction member 325 can be magnetically connected with the second magnetic attraction member 327, so as to avoid the clamp mechanism 30 from shaking in the vertical direction during the feeding or discharging of the pole piece 1, and affect the feeding or discharging effect of the pole piece 1. The thickness of the first magnetic attraction member 325 and the second magnetic attraction member 327 can be adjusted according to the actual installation requirements, so as to further ensure that the clamp mechanism 30 is just in the horizontal state after being turned over, avoid the working surface of the clamp mechanism 30 relative to the rack 10 from being inclined after being turned over, and ensure the quality of the feeding or discharging of the pole piece 1.

[0060] In an embodiment, please refer to Figure 7 , the rotating assembly 32 can further comprise a guide rail 327, the guide rail 327 is connected to the rack 3213 and is slidably connected to the connecting seat 323, the slide rail is used for guiding and limiting the linear motion of the rack 3213, so as to avoid the rack 3213 from shaking left and right during the motion.

[0061] In an embodiment, please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 , the jaw opening mechanism 40 can comprise a second power mechanism 41 and a third power mechanism 42. The second power mechanism 41 is used for controlling the opening of the clamp mechanism 30. The third power mechanism 42 is connected with the second power mechanism 41 and is configured to drive the second power mechanism 41 away from the clamp mechanism 30 when the rotating assembly 32 drives the clamp mechanism 30 to rotate, and drive the second power mechanism 41 to approach the clamp mechanism 30 when the clamp mechanism 30 needs to be opened.

[0062] It can be understood that the second power mechanism 41 can interfere with the rotation of the clamp mechanism 30, therefore, when the clamp mechanism 30 rotates, the third power mechanism 42 drives the second power mechanism 41 to move away from the clamp mechanism 30, and when the clamp mechanism 30 needs to be opened, the third power mechanism 42 drives the second power mechanism 41 to approach the clamp mechanism 30, and then the second power mechanism 41 controls the opening of the clamp mechanism 30.

[0063] Further, please refer to Figure 8 and Figure 9The second power mechanism 41 can include a top plate 411, a second cylinder 412 and a third mounting base 44, the second cylinder 412 can be mounted on the third mounting base 44 and in driving connection with the top plate 411 to drive the top plate 411 to push the clamp mechanism 30 to open, the third power mechanism 42 can include a third cylinder 421 and a track 43, the third mounting base 44 is slidingly arranged on the track 43, and the third cylinder 421 is in driving connection with the third mounting base 44 to drive the second cylinder 412 to move close to or away from the rack 10, so as to avoid the second cylinder 412 from moving left and right during the movement, thus causing the second cylinder 412 to fail to accurately control the opening of the clamp mechanism 30.

[0064] It can be seen that before or during the rotation of the clamp mechanism 30 driven by the rotating assembly 32, the third cylinder 421 drives the third mounting base 44 to drive the second cylinder 412 and the top plate 411 to move away from the rack 10, after the rotation of the clamp mechanism 30, the third cylinder 421 drives the third mounting base 44 to move reversely, and then the second cylinder 412 drives the top plate 411 to move upward, and the top plate 411 controls the opening of the clamp mechanism 30.

[0065] In the embodiment, please refer to Figure 1 The number of the clamp jaw opening mechanisms 40 can be two, and the two clamp jaw opening mechanisms 40 can be respectively arranged at the feeding station 11 and the discharging station 12, so as to save the control process of moving the clamp jaw opening mechanisms 40 back and forth. When the pole piece 1 is fed, the right clamp jaw opening mechanism 40 can control the clamp mechanism 30 to open before clamping the pole piece 1. When the pole piece 1 is discharged, the left clamp jaw opening mechanism 40 controls the clamp mechanism 30 to release the clamping of the pole piece 1. Of course, in other embodiments, the number of the clamp jaw opening mechanisms 40 is one, and the clamp jaw opening mechanism 40 is mounted on the driving mechanism 50, and the clamp jaw opening mechanism 40 is driven by the driving mechanism 50 to move between the feeding station 11 and the discharging station 12, so as to realize the sharing of the clamp jaw opening mechanisms 40.

[0066] In an embodiment, please refer to Figure 1 , Figure 5 and Figure 10The tab cleaning device can further include a lifting assembly 33 for driving the clamp mechanism 30 to enter and exit the cleaning mechanism 20. When the tab 2 of the tab sheet 1 needs to be cleaned, the lifting assembly 33 drives the clamp mechanism 30 to drive the tab 2 to enter the cleaning mechanism 20. The cleaning mechanism 20 can remove the coating through physical or chemical reaction of a specific cleaning liquid, so that the cleaning mechanism 20 can clean the coating in the designated area of the tab sheet 1 to expose the tab 2, and can also ensure that the tab 2 foil is not oxidized, thereby ensuring the welding quality of the tab 2 in ultrasonic welding. When the tab 2 is cleaned, the lifting assembly 33 drives the clamp mechanism 30 to drive the tab 2 to exit the cleaning mechanism 20. The automatic cleaning of the tab 2 can be realized by controlling the lifting assembly 33, and compared with manual control, the lifting distance can be uniform, and effective cleaning can be ensured.

[0067] Further, referring to Figure 1 , Figure 5 and Figure 10 , the lifting assembly 33 can include an abutting structure 331 and an elastic structure 332. The abutting structure 331 can be arranged on the rack 10. The elastic structure 332 can be elastically connected between the abutting structure 331 and the clamp mechanism 30, and the elastic structure 332 is configured to elastically deform when the clamp mechanism 30 abuts against the abutting structure 331 to enter the cleaning mechanism 20, and elastically reset when the clamp mechanism 30 is separated from the abutting structure 331, so that the clamp mechanism 30 exits the cleaning mechanism 20.

[0068] It can be understood that when the tab 2 of the tab sheet 1 needs to enter the cleaning mechanism 20, the abutting structure 331 abuts against the elastic structure 332 to drive the clamp mechanism 30 to move downward, so that the tab 2 can enter the cleaning mechanism 20. In this process, the elastic mechanism is elastically deformed; after the tab 2 is cleaned, the elastic structure 332 can be separated from the abutting limit of the abutting structure 331, and the elastic structure 332 is elastically reset to drive the clamp mechanism 30 to drive the tab 2 to exit the cleaning mechanism 20, and the reverse control is omitted through the elastic reset, so that the control process is more simple.

[0069] Further, referring to Figure 1 and Figure 5 , the elastic structure 332 can include a fixing seat 3321, a first guide shaft 3322, a second guide shaft 3323, and a spring 3324. Figure 5The first guide shaft is slidably arranged in the fixed seat 3321, so that the first guide shaft can move relative to the rack 10 along the extension direction of the first guide shaft. The guide shaft mounting seat 3323 can be mounted on the clamp mechanism 30, and is used to fix the two ends of the first guide shaft, so that the clamp mechanism 30 can move synchronously with the first guide shaft relative to the rack 10. The first elastic member 3322 can be sleeved on the first guide shaft and can be elastically connected between the fixed seat 3321 and the guide shaft mounting seat 3323. The first elastic member 3322 can be a spring or a rubber sleeve. The abutting portion 3325 can be mounted on the guide shaft mounting seat 3323. When the abutting structure 331 provided on the rack 10 abuts against the abutting portion 3325, the guide shaft mounting seat 3323 and the first guide shaft drive the clamp mechanism 30 to move downward relative to the fixed seat 3321 to enter the cleaning mechanism 20 for cleaning, and the first elastic member 3322 is elastically deformed. When the abutting portion 3325 is separated from the abutting structure 331, the first elastic member 3322 is elastically reset to drive the first guide shaft and the guide shaft mounting seat 3323 to drive the clamp mechanism 30 to move reversely relative to the fixed seat 3321, so that the tab 2 of the pole piece 1 is separated from the cleaning mechanism 20.

[0070] In the embodiment, please refer to Figure 1 、 Figure 5 and Figure 10 , the abutting portion 3325 can include a roller and a movable seat 3324. One end of the movable seat 3324 is connected with the guide shaft mounting seat 3323, and the other end is provided with a roller, which can be a cam follower. The abutting structure 331 drives the roller to drive the movable seat 3324 to move downward, and the downward movement of the movable seat 3324 can drive the guide shaft mounting seat 3323 and the first guide shaft to move downward, thereby driving the clamp mechanism 30 to drive the tab 2 to extend into the cleaning mechanism 20. By arranging the roller, the friction between the roller and the abutting structure 331 can be reduced, thereby facilitating the drive mechanism 50 to drive the clamp mechanism 30 to move between the feeding station 11, the cleaning station 13 and the discharging station 12.

[0071] In the embodiment, please refer to Figure 5 , the elastic structure 332 can further include a linear bearing 3326, which is sleeved on the first guide shaft and is mounted on the fixed seat 3321. The linear bearing 3326 is used to guide and limit the linear movement of the first guide shaft, so as to avoid the shaking of the first guide shaft during movement, thereby affecting the clamp mechanism 30 to drive the tab 2 to extend into the cleaning mechanism 20.

[0072] In an embodiment, referring to Figure 1 and Figure 10 The abutting structure 331 can include a first abutting plate 3311 and a second abutting plate 3313. The first abutting plate 3311 is two in number and is oppositely mounted on the two sides of the rack 10. The first abutting plate 3311 has an inclined abutting surface 3312 for abutting and guiding the elastic structure 332. The second abutting plate 3313 is mounted on the rack 10 and is connected to the first abutting plate 3311 in a lifting manner. The abutting surface 3312 of the second abutting plate 3313 can be configured as a flat surface 3314 for abutting with the elastic structure 332.

[0073] Referring to Figure 1 , Figure 5 , Figure 7 and Figure 10 After the clamp mechanism 30 is fed on the feeding station 11, in the process of moving left driven by the driving mechanism 50, the elastic structure 332 will abut against the abutting surface 3312 of the first abutting plate 3311 on the right side. The guide shaft mounting seat 3323 and the first guide shaft drive the clamp mechanism 30 to move downward relative to the fixed seat 3321. Then the clamp mechanism 30 continues to move left to the second abutting plate 3313 and is kept in position by the flat surface of the second abutting plate 3313. At this time, the second abutting plate 3313 can be adjusted to rise and fall according to the requirements to adapt to different degrees of entering the cleaning mechanism 20. During the cleaning process of the tab 2 of the pole piece 1, the elastic structure 332 is always in abutment with the flat surface 3314 of the second abutting plate 3313, and the first elastic member 3322 is compressed. After the tab 2 of the pole piece 1 is cleaned, the driving mechanism 50 drives the clamp mechanism 30 to move to the first abutting plate 3311 on the left side and gradually disengage from the abutting surface 3312 of the first abutting plate 3311. The first elastic member 3322 is elastically reset to drive the first guide shaft and the guide shaft mounting seat 3323 to move the clamp mechanism 30 relative to the fixed seat 3321 in the opposite direction, so that the tab 2 of the pole piece 1 leaves the cleaning mechanism 20.

[0074] Further, referring to Figure 10The abutting structure 331 can further include a first adjusting member 3315 and a first adjusting block 3317. The first adjusting block 3317 can be mounted on the rack 10, the first adjusting member 3315 can be arranged through the first adjusting block 3317 and the first abutting plate 3311, the first adjusting member 3315 can be a bolt, the first abutting plate 3311 is mounted on the rack 10 through the first adjusting member 3315 and the first adjusting block 3317, and the height of the first abutting plate 3311 to the cleaning mechanism 20 can be adjusted by rotating the first adjusting member 3315, so as to adjust the depth of the abutting structure 331 driving the abutting part 3325 to push the clamp mechanism 30 into the cleaning mechanism 20. For example, when the length of the tab 2 of the pole piece 1 is relatively long, the user can rotate the first adjusting member 3315 to reduce the distance between the first abutting plate 3311 and the cleaning mechanism 20, so as to increase the length of the tab 2 extending into the cleaning mechanism 20.

[0075] Referring to Figure 10 The abutting structure 331 can further include a second adjusting member 3316 and a second adjusting block 3318. The second adjusting block 3318 can be mounted on the rack 10, the second adjusting member 3316 can be arranged through the second adjusting block 3318 and the second abutting plate 3313, the second adjusting member 3316 can be a bolt, the second abutting plate 3313 is mounted on the rack 10 through the second adjusting member 3316 and the second adjusting block 3318, and the height of the second abutting plate 3313 to the cleaning mechanism 20 can be adjusted by rotating the second adjusting member 3316, so as to adjust the depth of the clamp mechanism 30 extending into the cleaning liquid controlled by the abutting structure 331.

[0076] In another embodiment, the abutting plate can be replaced by a groove cam, and the groove cam abuts against the roller to enable the clamp mechanism 30 to drive the tab 2 to extend into the cleaning liquid.

[0077] In another embodiment, the lifting assembly 33 can also be an active adjusting mechanism such as an electric cylinder, a pneumatic cylinder, etc. The electric cylinder is in driving connection with the clamp mechanism 30, and is used to drive the clamp mechanism 30 to drive the tab 2 to extend into or out of the cleaning liquid.

[0078] In an embodiment, referring to Figures 1 to 5 and Figure 9 The number of the clamp mechanisms 30 can be multiple, and the multiple clamp mechanisms 30 can clamp multiple pole pieces 1 respectively, so as to improve the cleaning efficiency of the tab 2.

[0079] The clamping mechanism 30 may include a clamping arm 312, which is configured to clamp the electrode 1 under elastic action. A jaw opening mechanism 40 is used to overcome the elastic action on the clamping arm 312, thereby controlling the clamping arm 312 to open. During loading or unloading, the jaw opening mechanism 40 controls the clamping arm 312 to open. At other times, the clamping arm 312 is in a closed state under elastic action. The use of elastic action in this embodiment facilitates the clamping and opening control of the clamping arm 312.

[0080] For further details, please refer to Figures 2 to 6 The clamping mechanism 30 may include a clamping seat 311, a second guide shaft 3123, and a second elastic member 313. The clamping seat 311 is used to hold the electrode 1, and the clamping arm 312 is hinged to the clamping seat 311 to fix the electrode 1 to the clamping seat 311. The second guide shaft 3123 slidably passes through the clamping seat 311 and is hinged to the clamping arm 312. The second elastic member 313 may be a spring and may be elastically connected between the end of the second guide shaft 3123 away from the clamping arm 312 and the clamping seat 311. Furthermore, the end of the second guide shaft 3123 away from the clamping arm 312 may have a protrusion 3127, and the spring is elastically connected between the protrusion 3127 and the clamping seat 311. The gripper opening mechanism 40 (such as the top plate 411 mentioned above) is used to drive the second guide shaft 3123 to overcome the elastic force of the second elastic member 313, so as to drive the gripping arm 312 to rotate and open. When the gripper opening mechanism 40 disengages from the second guide shaft 3123, the second elastic member 313 elastically resets to push the second guide shaft 3123 to move in the opposite direction, thereby closing the gripping arm 312.

[0081] Understandably, please combine Figure 2 and Figure 6 When the clamping mechanism 30 is in the loading / unloading state, the gripper opening mechanism 40 drives the second guide shaft 3123 to move upward. The movement of the second guide shaft 3123 can drive the clamping arm 312 to rotate and open, and the second elastic element 313 is compressed. After the electrode 1 is loaded or unloaded, the gripper opening mechanism 40 no longer abuts against the second guide shaft 3123. The second elastic element 313 elastically resets and drives the second guide shaft 3123 to move downward. The movement of the second guide shaft 3123 can control the clamping arm 312 to rotate in the opposite direction, so that the clamping arm 312 is in the closed state.

[0082] In this embodiment, please refer to Figures 2 to 5 The combination relationship between the clamping seat 311 and the clamping arm 312 can be as follows:

[0083] In one embodiment, a clamping seat 311 is equipped with a clamping arm 312, and the clamping arm 312 holds the electrode 1 against the clamping seat 311 under elastic action.

[0084] In another embodiment, please combineFigure 3 A clamping base 311 is equipped with multiple clamping arms 312. For example, a clamping base 311 can be equipped with three clamping arms 312. The three clamping arms 312 are circumferentially spaced on the clamping base 311. The electrode 1 can be stably and reliably abutted on the clamping base 311 by the three clamping arms 312.

[0085] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 8 and Figure 9 The electrode cleaning device is equipped with two clamping seats 311 and six clamping arms 312. Three second power mechanisms 41 are provided to open the clamping arms 312, with two of the second power mechanisms 41 located on one side of the frame 10. Figure 2 The two second power mechanisms 41 are located on the side away from the first power mechanism 322 and are connected to the third power mechanism 42. Because these two second power mechanisms 41 interfere with the rotation of the clamping mechanism 30, the third power mechanism 42 needs to drive these two second power mechanisms 41 to move away from the frame 10 when the clamping mechanism 30 rotates; another second power mechanism 41 is located on the other side of the frame 10 ( Figure 2 The position of the second power mechanism 41 (located on the side closer to the first power mechanism 322) does not affect the rotation of the clamping mechanism 30, so it does not need to "give way" to the clamping mechanism 30 during the rotation of the clamping mechanism 30. Each second power mechanism 41 can control the opening of the two clamping arms 312 respectively.

[0086] Of course, in other embodiments, two second power mechanisms 41 may be provided and arranged opposite to each other on both sides of the frame 10. One second power mechanism 41 is used to control the opening of the four clamping arms 312 located on one side of the frame 10, and the other second power mechanism 41 is used to control the opening of the two clamping arms 312 located on the other side of the frame 10.

[0087] The second guide shaft 3123 and the clamping arm 312 can be directly hinged or indirectly hinged through other mechanisms. For example, in this embodiment, please refer to... Figure 3 , Figure 4 and Figure 6, the clamping arm 312 can include a first clamping jaw arm 3121 and a second clamping jaw arm 3122, one end of the second clamping jaw arm 3122 is hinged to the first clamping jaw arm 3121, the other end is hinged to the clamping seat 311, and the second guide shaft 3123 is directly hinged to the first clamping jaw arm 3121 to drive the first clamping jaw arm 3121 to rotate open or close through the movement of the second guide shaft 3123. Of course, in other embodiments, the clamping arm 312 can only include the first clamping jaw arm 3121, and a series of connecting rod structures can be hinged between the second guide shaft 3123 and the first clamping jaw arm 3121, so that the opening or closing of the first clamping jaw arm 3121 can also be controlled by controlling the movement of the second guide shaft 3123. By controlling the opening of the first clamping jaw arm 3121, the pole piece 1 can be loaded and unloaded on the clamping seat 311, and by controlling the closing of the first clamping jaw arm 3121, the pole piece 1 can be stably abutted on the clamping seat 311.

[0088] Further, please combine Figure 6 , the end of the first clamping jaw arm 3121 away from the second clamping jaw arm 3122 can be provided with a rubberized clamping block 3124, which can be a rubber part. By providing the rubberized clamping block 3124, the friction force of the first clamping jaw arm 3121 to the pole piece 1 can be increased, the tab 2 of the pole piece 1 can be prevented from sliding off the clamping seat 311 during cleaning, and the surface of the pole piece 1 can also be protected.

[0089] The clamp mechanism 30 can also include a first mounting seat 3125 and a bushing 3126. The first mounting seat 3125 is provided on the clamping seat 311, one end of the second clamping jaw arm 3122 is hinged to the first mounting seat 3125, the bushing 3126 is sleeved on the second guide shaft 3123, and is mounted on the clamping seat 311 for guiding the second guide shaft 3123 to move linearly.

[0090] In related technologies, the clamping jaw holds the pole piece 1 under the action of the air cylinder, the clamping jaw is installed on the turntable and rotates with the turntable, and the wires (signal lines) and air pipes of the air cylinder also rotate with the clamping jaw disc at this time. At this time, a slip ring needs to be added to avoid the wires and air pipes from being easily entangled. However, in the application of the circular track clamp, the slip ring cannot solve the problem of entanglement of the wires and air pipes.

[0091] The clamp mechanism 30 and the clamp jaw opening mechanism 40, and the first cylinder 3222 in the rotating assembly 32 are designed in a split body. It can be understood that when the clamp mechanism 30 needs to rotate, the connecting piece 3221 on the drive shaft of the first cylinder 3222 is connected to the connecting joint 326 laterally, and then the drive rack 3213 is driven to move, so that the rotating shaft 3211 drives the clamp mechanism 30 to rotate. Since the first cylinder 3222 does not rotate, the wires and air pipes of the first cylinder 3222 will not be wound by rotation. Since the clamping arm 312 abuts the pole piece 1 on the clamping seat 311 under the action of elasticity, the problem of winding of wires and air pipes will not occur during the rotation of the clamping arm. When the clamping arm 312 needs to be opened, the third cylinder 421 drives the second cylinder 412 to approach the clamping arm 312, and the second cylinder 412 controls the opening of the clamping arm 312. Therefore, the second cylinder 412 and the third cylinder 421 will not rotate during the rotation of the clamp mechanism 30, so that the wires (signal lines) and air pipes of the second cylinder 412 and the third cylinder 421 will not be wound by rotation. The problem of winding of wires and air pipes is avoided, and the problem of supplying compressed air and power during the use of the circulating clamp is solved.

[0092] In an embodiment, please combine Figure 1 and Figure 11 The pole tab cleaning device can further include a drying mechanism 60 mounted to the rack 10, and the drying mechanism 60 is used to dry the pole tab 2 of the cleaned pole piece 1. Avoiding the pole tab 2 from adhering with cleaning liquid.

[0093] Further, please combine Figure 1 and Figure 11 The drying mechanism 60 can include a blowing cylinder 61, a blowing pipe 62, a hot air generator 63, and a fifth mounting seat 64. The blowing cylinder 61 is mounted to the discharging station 12 of the rack 10, and is in transmission connection with the fifth mounting seat 64. The hot air generator 63 and the blowing pipe 62 are in communication, and are both mounted to the fifth mounting seat 64. The hot air pipe is provided with a plurality of air holes 621, and the hot air generated by the hot air generator 63 is blown out through the air holes 621 of the blowing pipe 62. When the pole tab 2 needs to be dried, the blowing cylinder 61 drives the fifth mounting seat 64 to drive the hot air generator 63 and the blowing pipe 62 to move upward, so as to fully dry the pole tab 2.

[0094] In an embodiment, please combine Figure 1 The driving mechanism 50 can be a linear motor or other linear driving device.

[0095] In another embodiment, the driving mechanism 50 can be a conveyor belt mechanism, so that the clamp mechanism 30 can run in a ring shape, realizing the circulation use of multiple clamps, and greatly improving the cleaning efficiency of the pole tab 2.
