Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to a pole piece correction device. Background Art

[0002] Cell stacking involves stacking multiple battery cells together in a specific pattern to form a single unit. The positive and negative electrode assembly process plays a crucial role in the cell stacking process. Prior to assembly, the accuracy of the positive and negative electrode positioning plays a crucial role in determining the quality and efficiency of the assembly. Therefore, in the field of cell stacking technology, ensuring accurate control of the positive and negative electrode positioning is paramount.

[0003] Currently, the electrode position is typically detected using a CCD (Charge Coupled Device) flying or fixed-shot method. A robot is then positioned on a correction platform based on the CCD image, correcting the deviation. After correction is complete, the electrodes are stacked. However, the flying-shot method is unstable and prone to false detections and missed detections. The fixed-shot method requires waiting for the image to be captured before the correction robot is grasped. This multiple interaction is prone to interaction errors. Consequently, existing methods have low accuracy in detecting the electrode position, resulting in poor correction results. Utility Model Content

[0028] Cell stacking involves stacking multiple battery cells together in a specific pattern to form a single unit. The positive and negative electrode assembly process plays a crucial role in the cell stacking process. Prior to assembly, the accuracy of the positive and negative electrode positioning plays a crucial role in determining the quality and efficiency of the assembly. Therefore, in the field of cell stacking technology, ensuring accurate control of the positive and negative electrode positioning is paramount.

[0029] Currently, the electrode position is typically detected using a CCD (Charge Coupled Device) flying or fixed-shot method. A robot is then positioned on a correction platform based on the CCD image, correcting the deviation. After correction is complete, the electrodes are stacked. However, the flying-shot method is unstable and prone to false detections and missed detections. The fixed-shot method requires waiting for the image to be captured before the correction robot is grasped. This multiple interaction is prone to interaction errors. Consequently, existing methods have low accuracy in detecting the electrode position, resulting in poor correction results.

[0030] In order to solve the above problems, this embodiment proposes a pole piece correction device.

The driving mechanism is connected to the discharge mechanism to drive the discharge plate to be pressed onto the adsorption device, and further can drive the pole piece to be tested adsorbed by the second adsorption portion on the discharge plate to move. When the first adsorption portion and the second adsorption portion are positioned relative to each other, the adsorption device can adsorb the pole piece to be tested from the second adsorption portion to the first adsorption portion, reducing the error caused by multiple interactions of the manipulator, so that the correction platform can correct the pole piece to be tested on the first adsorption portion, ensuring the accuracy of the position of the pole piece during placement and correction. In this embodiment, the transfer of the electrode to be tested is achieved by a second adsorption part provided on the discharge mechanism and a first adsorption part provided on the correction mechanism, ensuring that the electrode to be tested is in the correct position and direction after the transfer, and the mutual cooperation of the two adsorption parts can reduce the interaction error during the transfer of the electrode, avoid direct contact with the surface of the electrode during the transfer of the electrode, reduce the risk of scratches or contamination, and improve the correction effect of the electrode.

[0031] Please refer to Figure 1 , Figure 1 It is a structural schematic diagram of the pole piece correction device provided in an embodiment of the present application.

[0032] In some embodiments, the pole piece correction device includes a correction mechanism, a discharge mechanism and a drive mechanism. The structure of the pole piece correction device is described in detail below.

[0033] In some embodiments, the deflection correction mechanism includes a deflection correction platform 210 and an adsorption device disposed above the deflection correction platform 210, wherein the adsorption device is provided with a first adsorption portion 230. The deflection correction platform 210 is used to photograph the electrode to be tested and to correct the deflection of the electrode to be tested. The position of the electrode to be tested is detected by photographing the electrode to be tested, and the accuracy of the position of the electrode to be tested is ensured by correcting the deflection of the electrode to be tested, thereby facilitating the alignment of the electrode pieces when the electrode pieces are subsequently stacked, thereby improving the deflection correction effect.

[0034] The discharge mechanism is arranged on one side of the correction mechanism. The discharge mechanism includes a discharge plate 100 and a second adsorption portion 110 arranged on the discharge plate 100. The second adsorption portion 110 is used to adsorb the electrode to be tested, thereby achieving adsorption and fixation of the electrode to be tested, which facilitates the subsequent transportation of the electrode to be tested.

[0035] The driving mechanism is connected to the discharge mechanism to drive the discharge plate to be pressed onto the adsorption device, so that the first adsorption portion 230 on the adsorption device adsorbs the electrode to be tested on the discharge plate. Specifically, when the first adsorption portion 230 and the second adsorption portion 110 are relative to each other, that is, the first adsorption portion 230 and the second adsorption portion 110 are parallel to each other, the adsorption device can adsorb the electrode to be tested from the second adsorption portion 110 of the discharge plate to the first adsorption portion 230 on the correction mechanism, so that the correction platform 210 in the correction mechanism corrects the electrode to be tested on the first adsorption portion 230. The mutual cooperation of the two adsorption portions can reduce the interaction error during the transfer of the electrode, avoid direct contact with the electrode surface during the transfer of the electrode, reduce the risk of scratches or contamination, and improve the correction effect of the electrode.

[0036] It should be noted that the second adsorption part 110 in this embodiment can be an adsorption hole, an adsorption groove, etc., and there can be one or more second adsorption parts 110 in this embodiment. The specific number of the second adsorption parts 110 is not specifically limited in this embodiment. This embodiment is described by taking four second adsorption parts 110 as an example.

[0037] It is worth noting that the adsorption device in this embodiment can be a suction plate, a suction cup, etc., and the side of the adsorption device connected to the correction table 210 is the lower surface, and the first adsorption part 230 is arranged on the upper surface of the adsorption device to facilitate the subsequent adsorption of the electrode to be tested, wherein the number of the first adsorption parts 230 is greater than or equal to the number of the second adsorption parts 110, and when the discharge plate 100 presses the adsorption device, the positions of the second adsorption parts 110 and the first adsorption parts 230 correspond, and the adsorption area of the first adsorption part 230 is greater than or equal to the adsorption area of the second adsorption part 110, which can ensure the accuracy of the position of the electrode to be tested during the correction process and avoid the offset of the electrode to be tested. In addition, in this embodiment, multiple second adsorption parts 110 and first adsorption parts 230 are provided to simultaneously realize the placement and correction of multiple electrode to be tested, improve the correction efficiency of the electrode, and further improve the production and processing efficiency of the electrode.

[0038] In some embodiments, the correction platform 210 is provided with a camera and a correction device. When the second adsorption part 110 adsorbs the electrode to be tested, the camera takes a picture of the electrode to be tested to realize the photographic detection of the electrode to be tested. When the vacuum is broken in the second adsorption part 110 and the first adsorption part 230 adsorbs the electrode to be tested, the correction program on the correction device is started to realize the correction of the electrode to be tested. By integrating the camera and the correction device into the correction platform 210, the interactive operations in the electrode correction process can be reduced, and the interactive errors caused by the interactive operations are further reduced.

[0039] Among them, the correction mechanism includes a control cabinet 240 and a photographing device (not shown in the figure). The control cabinet 240 is arranged below the correction platform 210. The control cabinet 240 is used to accommodate the photographing device and the controller of the correction platform 210, thereby effectively utilizing space and avoiding the equipment occupying too much working area. It is convenient for wiring and maintenance while also making the equipment more neat and beautiful.

[0040] It can be understood that the photographing device in this embodiment uses CCD to photograph the pole piece to be tested. During the pole piece correction process, CCD can be used to detect and record changes in the polarization state of light of the pole piece. Through CCD, the polarization state of light during the pole piece correction process can be monitored in real time to help adjust the angle of the pole piece to ensure that the light achieves the desired polarization effect.

[0041] In some embodiments, the second adsorption portion 110 of this embodiment is arranged on the side of the discharge plate 100 facing the first adsorption portion 230, so that the electrode to be tested can be transferred through the mutual cooperation of the second adsorption portion 110 and the first adsorption portion 230, reducing the errors caused by multiple interactions and improving the stability of the transfer of the electrode to be tested.

[0042] In some embodiments, the driving mechanism can drive the discharge plate 100 to move along a preset direction to realize horizontal or vertical movement of the discharge mechanism. The driving mechanism is also used to drive the discharge plate 100 to be pressed onto the adsorption device so that the correction platform 210 can shoot the electrode to be tested. The stability of the electrode to be tested during the shooting process is ensured by the pressing of the discharge plate 100 and the adsorption of the second adsorption part 110 on the discharge plate 100, thereby avoiding the position movement of the electrode to be tested during the shooting process. After the electrode to be tested is shot, the second adsorption part 110 breaks the vacuum without Then the electrode to be tested is adsorbed, and at this time the discharge plate 100 still maintains a pressed state. The first adsorption part 230 is used to adsorb the electrode to be tested after being photographed, so as to realize the transfer of the electrode to be tested and ensure that the electrode to be tested is in the correct position and direction during the transfer process. After the first adsorption part 230 adsorbs the electrode to be tested, the correction platform 210 corrects the electrode to be tested on the first adsorption part 230 to realize the detection of the position of the electrode to be tested, ensure the flatness of the electrode to be tested when stacking, reduce the failure rate caused by poor stacking, and improve the stability and reliability of the equipment.

[0043] It should be noted that the preset direction in this embodiment can be horizontal movement along the length direction of the unloading plate 100 ( Figure 1 Y-axis direction in the drawing), or vertical movement along a vertical direction perpendicular to the unloading plate 100 ( Figure 1 The Z-axis direction in the present embodiment is not specifically limited.

[0044] It is worth noting that in this embodiment, one or more discharge mechanisms and correction mechanisms can be provided to improve the detection efficiency of the electrode to be tested. This embodiment does not impose any specific limitation on the number of discharge mechanisms and correction mechanisms.

[0045] In some embodiments, the electrode correction device also includes a feeding mechanism 300 and a picking mechanism. The feeding mechanism is arranged at the feeding end of the discharge mechanism. The feeding mechanism is used to place the electrode to be tested into the second adsorption portion 110 of the discharge plate 100 to realize the delivery of the electrode to be tested. The picking mechanism is arranged on the correction mechanism. Specifically, the picking mechanism of the embodiment of the present application is arranged above the correction mechanism. The picking mechanism is used to move the electrode to be tested after correction, so that the electrode after correction can be moved to the next process, thereby improving the processing efficiency of the electrode, reducing manual intervention, reducing operating costs, and avoiding the impact that may be caused by human error.

[0046] It should be noted that the number of the material taking mechanisms in this embodiment can be set according to the number of the correction mechanisms or the needs of the user, and this embodiment does not impose any specific restrictions.

[0047] It can be understood that the material taking mechanism in this embodiment can move the electrode to be tested after correction to the electrode composite module or the electrode stacking module, thereby completing the processing of the battery cell and improving the processing efficiency.

[0048] In some embodiments, the drive mechanism includes a first drive member 410 and a second drive member 420. The first drive member 410 is connected to the discharge mechanism and is used to drive the discharge plate 100 to move along a first direction, thereby achieving the capture and discharge of the electrode to be tested, and realizing the transportation of the electrode to be tested. The second drive member 420 is connected to the retrieving mechanism and is used to drive the retrieving mechanism to move along a second direction.

[0049] In some embodiments, the first driving member 410 is provided with a mounting plate 411, the mounting plate 411 is provided with a track groove, and the discharge plate 100 is provided with a follower device cooperating with the mounting plate 411. The follower device is used to slide along the track groove of the mounting plate 411 to drive the discharge plate 100 to move, thereby realizing the movement of the discharge mechanism and improving the processing efficiency of the electrode to be tested.

[0050] It can be understood that the first driving member 410 and the second driving member 420 in the embodiment of the present application can be a linear motor module, a single-axis manipulator, etc. The embodiment of the present application does not impose any specific restrictions on the selection of the first driving member 410 and the second driving member 420.

[0051] It should be noted that the mounting plate 411 is provided with a track groove, which is usually set to a curved or curved shape. The track groove will be designed into a corresponding shape according to the required motion path. The follower device can be a bearing or a part similar to a cylinder, and its outer surface usually has a protrusion. The shape of the random device can be designed into various curves or contours as needed. The follower device can move along the track groove opened on the mounting plate 411, thereby driving the discharge plate 100 to move.

[0052] Taking the mounting plate 411 as a cam track plate and the follower device as a cam follower as an example, the coordination process of the mounting plate 411 and the follower device of this embodiment is explained. The cam follower in this embodiment is a part mounted on the discharge plate 100, and its bottom has a protrusion that cooperates with the cam track plate. When the cam follower slides in the groove of the cam track plate, the shape of the cam will cause the cam follower to be subjected to different forces during the sliding process, so that it can move along different directions.

[0053] It is worth noting that the first direction and the second direction in this embodiment are different, wherein the first direction is the direction in which the first driving member 410 drives the unloading plate 100 to move. The first direction is related to the setting shape of the mounting plate 411, that is, the first direction can be the direction of movement along the length direction of the unloading plate 100 ( Figure 1 The Y-axis direction in Figure 1 The second direction is the direction in which the second driving member 420 drives the material taking mechanism to move, for example, the material taking mechanism is driven to move along the width direction of the material discharging plate 100 ( Figure 1 Therefore, the first direction and the second direction in this embodiment are different directions.

[0054] In some embodiments, the driving mechanism also includes a first guide rail 430 and a second guide rail 440. The first guide rail 430 is arranged on both sides of the first driving member 410, so as to guide the follower device to maintain a stable trajectory during linear motion, ensuring that the follower device can move along the Y-axis direction on the mounting plate 411 according to design requirements while also being able to move along the Z-axis direction, thereby improving the accuracy and stability of the system. The second guide rail 440 is arranged on both sides of the second driving member 420 to avoid shaking during the material picking process. This embodiment enhances the structural stability of the motor module by setting the guide rail, avoids shaking or deformation during movement, and ensures the normal operation and work efficiency of the equipment.

[0055] In some embodiments, the material picking mechanism includes a material picking robot 510, a connecting plate 520 and a material picking plate 500. The connecting plate 520 is used to connect the material picking robot 510 and the material picking plate 500. The material picking plate 500 is used to absorb the electrode to be tested after correction. The second driving member 420 is connected to the material picking robot 510 to drive the material picking robot 510 to drive the material picking plate 500 to move above the correction mechanism, thereby realizing the adsorption of the electrode after correction and the transfer of the electrode after correction, reducing manual intervention and improving production efficiency and consistency.

[0056] It should be noted that the number of feeding plates 500 in this embodiment corresponds to the number of adsorption devices in the correction mechanism, and the setting position of the feeding plate 500 corresponds to the position of the adsorption device, so as to achieve accurate absorption of the electrode and avoid feeding deviation. The mutual cooperation between the manipulator, the connecting plate 520 and the feeding plate 500 reduces the possibility of human operation errors, improves the accuracy and stability of feeding, and is conducive to improving product quality and production efficiency.

[0057] Please refer to Figure 2 , Figure 2 It is a structural schematic diagram of the discharge plate 100 provided in an embodiment of the present application.

[0058] In some embodiments, the discharge mechanism includes a transparent plate 120, which is arranged on the discharge plate 100 and overlaps with at least a portion of the second adsorption portion 110. The transparent plate 120 is used to press the detection part of the electrode to be tested, thereby preventing the camera from misjudging due to the tilting of the electrode part during detection, thereby ensuring the accuracy of the detection results.

[0059] It should be noted that the transparent plate 120 can be a high-transparency plate such as a glass plate, an acrylic plate, etc., and the number of transparent plates 120 corresponds to the number of second adsorption parts 110. Pressing the electrode to be tested with the transparent plate 120 can ensure that the detection part of the electrode is in a flat state, which is conducive to the detection of the electrode by the detection equipment. While pressing the electrode to be tested, it also plays a protective role to prevent external objects from causing damage or contamination to the electrode to be tested.

[0060] It is understandable that the material of the transparent plate 120 itself is transparent, which allows the operator to clearly see the condition of the electrode to be tested, facilitating operation and observation.

[0061] In some embodiments, the discharge plate 100 is provided with a blowing portion 130, which is arranged on the side of the discharge plate 100 facing the correction mechanism. The blowing portion 130 is used to blow air to the adsorption device. It can blow air to remove dust from the adsorption device before the electrode to be tested is placed on the adsorption device to prevent the electrode from being contaminated with dust, and also prevent dust from causing misjudgment in shooting detection.

[0062] It can be understood that the blowing portion 130 in this embodiment can be a blowing hole, a blowing channel, a blowing port, etc., and this embodiment does not impose any specific limitation.

[0063] Please refer to Figure 3 , Figure 3 It is a structural schematic diagram of the correction mechanism provided in an embodiment of the present application.

[0064] In some embodiments, the correction mechanism includes a light-emitting component 250, which is arranged below the adsorption device. The light-emitting component 250 is used to send light to facilitate the camera to detect the position and direction of the pole piece, facilitate subsequent more accurate correction operations, and further improve the accuracy and efficiency of the correction.

[0065] It is worth noting that the adsorption device in this embodiment is made of a transparent material, which enables the light emitted by the light-emitting element 250 to pass through the adsorption device, thereby improving the accuracy and efficiency of the correction.

[0066] In some embodiments, the pole piece correction device further includes a protective cover 600, which is arranged around the outside of the correction platform 210 and the material-retrieving mechanism to protect the correction platform 210 and the material-retrieving mechanism and avoid personal injury during the movement of the correction platform 210.

[0067] It will be appreciated that the deflection correction platform 210 in this embodiment is movable, and the protective cover 600 effectively encloses the deflection correction platform 210 and the retrieving mechanism, preventing personnel from accidentally contacting the moving components and thereby reducing the risk of injury during the movement of the deflection correction platform 210. Furthermore, the provision of the protective cover 600 prevents external debris or other objects from entering the range of motion of the deflection correction platform 210 and the retrieving mechanism, thereby preventing these objects from interfering with or damaging the operation of the equipment.

[0068] In some embodiments, the discharge mechanism also includes a reinforcing plate 140, which is arranged on the edge of the discharge plate 100 along the length direction of the discharge plate 100, thereby fixing the discharge plate 100, improving the stability of the discharge plate 100, and avoiding position deviation during the discharge process.

[0069] It can be understood that, by providing the reinforcing plate 140 , this embodiment can effectively increase the rigidity and stability of the discharge plate 100 , reduce the possibility of deformation or vibration of the discharge plate 100 during operation, and reduce position deviation during the discharge process.
