When the type of the battery cell is changed, the width of the pole piece and the diaphragm changes, and the deviation rectifying sensor also needs to be changed accordingly to meet the new requirements. Moreover, in the existing deviation rectifying structure, the deviation rectifying sensor can only adjust the position of the sensor by manual movement, that is, it is necessary for the operator to roughly move the deviation rectifying sensor to the vicinity of the target position first and then finely adjust it by rotating the fine adjustment nut. Therefore, when the width of the pole piece changes, it is necessary to manually calculate and adjust the position to which the deviation rectifying sensor needs to be moved to ensure that the path of the pole piece meets the requirements.

[0042] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] As Figure 1 shown, the present utility model provides a deviation rectifying device 100, which is applicable to scenarios such as automatic forming (such as winding and unwinding) of battery electrodes. Among them, the deviation rectifying device 100 is placed on a winding machine 200. The deviation rectifying device 100 is used to detect the position and width of the battery electrode during the winding or unwinding process on the winding machine 200. Furthermore, during the winding and unwinding processes, it realizes real-time monitoring and deviation rectification of the moving battery electrode on the production line, avoiding the problem of deviation and misalignment during the winding of the battery electrode.

[0044] In addition, the deviation rectifying device 100 provided in this embodiment is also used to automatically adjust the position of the deviation rectifying sensor 120 after the battery electrode is changed in type, for real-time monitoring and deviation rectification of the battery electrode after the type change, so that it is not necessary to change the type of the deviation rectifying sensor 120 at the same time as the battery electrode is changed in type, so that the deviation rectifying sensor 120 meets the monitoring and deviation rectification requirements of the electrode after the type change.

[0045] Exemplarily, the device includes a motor assembly 110, a deviation correction sensor 120, a touch screen 130, and a controller 140; optionally, the motor assembly 110 includes a servo motor and a slide rail mechanism, and the servo motor is connected to the slide rail mechanism; wherein, the deviation correction sensor 120 is disposed on the slide rail mechanism and is used to slide on the slide rail mechanism; the controller 140 is respectively connected to the servo motor and the touch screen 130, and the controller 140 is used to control the servo motor to drive the deviation correction sensor 120 to slide on the slide rail mechanism.

[0046] Wherein, the deviation correction sensor 120 is disposed in the unwinding area and / or the winding area of the winding machine 200, so that the deviation correction sensor 120 measures the width of the battery electrode sheet placed in the winding area or the unwinding area; that is, the deviation correction sensor 120 performs real-time monitoring and deviation correction on the battery electrode sheet in the winding area and / or the unwinding area.

[0047] In one example, with reference to Figure 2 , the deviation correction device 100 further includes a sensor mounting bracket 150. Wherein, the sensor mounting bracket 150 is disposed on the slide rail mechanism and is used to carry the deviation correction sensor 120. Exemplarily, the sensor mounting bracket 150 includes a rotating nut and a connecting seat; wherein, the connecting seat is used to place the deviation correction sensor 120; the rotating nut is used to drive the deviation correction sensor 120 on the connecting seat to deflect and / or lift after rotation, so as to adjust the placement angle and / or height of the deviation correction sensor 120.

[0048] That is, the sensor mounting bracket 150 can be set to carry the deviation correction sensor 120, and then the placement height and deflection angle of the deviation correction sensor 120 are adjusted, etc., so as to improve the reliability of the deviation correction sensor 120 for monitoring and deviation correction of the battery electrode sheet.

[0049] Optionally, the deviation correction sensor 120 can be selected from any one of a laser pair emission deviation correction sensor, an angle sensor, a photoelectric sensor, a magnetic encoder, and a piezoelectric sensor; the slide rail mechanism can be a lead screw module or a lead screw and other devices. The selection types, categories, and quantities of the deviation correction sensor 120, the slide rail mechanism, the touch screen 130, the controller 140, and the servo motor can be specifically set according to actual needs, and this embodiment does not limit this.

[0050] For reference, if the deviation correction sensor 120 is a laser pair emission deviation correction sensor; wherein, the laser pair emission deviation correction sensor includes a laser emission part and a laser reception part; further, the laser emission part is used to emit a laser beam, and the laser reception part is used to receive the laser beam reflected back by the battery electrode sheet and convert it into an electrical signal and input it to the controller 140, so that the controller 140 realizes the monitoring and deviation correction of the battery electrode sheet based on the electrical signal.

[0051] Exemplarily, the laser emission unit includes one or more laser emission tubes, wherein the laser emission tubes are configured to emit laser beams towards the battery electrode plate; the laser reception unit includes a lens group and a reception unit, the lens group is configured to focus the laser beams reflected back by the battery electrode plate; the reception unit is configured to convert the focused laser beams into electrical signals and send the electrical signals to the controller 140.

[0052] Wherein, the specific structure of the deviation correction sensor 120 and the components used, etc. can be adjusted and set accordingly according to actual requirements, and this embodiment does not limit this.

[0053] It should be noted that in the actual application scenario of the deviation correction device provided in this embodiment, when the battery electrode plate is changed in type, the touch screen 130 is configured to receive the width of the battery electrode plate after the battery cell type is changed input by the user; the controller 140 is configured to determine the target position that the deviation correction sensor 120 needs to move to currently when receiving the width of the battery electrode plate, so as to control the movement of the servo motor, so that the servo motor drives the deviation correction sensor 120 to move to the target position at a first speed.

[0054] It can be understood that after the battery electrode plate is changed in type, the controller 140 can determine the distance and direction that the deviation correction sensor 120 needs to move through the width of the electrode plate after the type change received by the touch screen 130, so as to control the movement of the servo motor, and mechanically drive the deviation correction sensor 120 to translate left and right on the slide rail mechanism to the target position. Thus, in this embodiment, by adjusting the position of the deviation correction sensor 120, it is adapted to the battery electrode plate after the type change, so as to ensure the reliability of the monitoring and deviation correction of the battery electrode plate before and after the type change, thereby avoiding replacing the deviation correction sensor 120 synchronously and saving costs. In addition, the data of this type change can be synchronously recorded and saved by the controller 140, that is, the position parameters of the deviation correction sensor 120 are saved according to different battery cell models, which is convenient for subsequent traceability. If the battery cell of the same model is changed again, the corresponding position parameters can be directly retrieved to automatically and quickly adjust the position of the deviation correction sensor 120, improving the monitoring and deviation correction efficiency of the battery electrode plate, and improving the overall production efficiency of the battery cell.

[0055] Wherein, in the process of controlling the deviation correction sensor 120 to move to the target position in this embodiment, it can be set that the servo motor is controlled to drive the deviation correction sensor 120 to move to the target position at a constant speed, that is, the first speed remains unchanged all the time, or the servo motor is controlled to drive the deviation correction sensor 120 to accelerate first and then decelerate, or to move at a constant speed first and then decelerate, etc.; wherein, the specific value and change situation of the first speed can be set accordingly according to actual requirements, and this embodiment does not limit this.

[0056] It should be noted that when the deviation correction sensor 120 moves to the target position, the edge position of the battery pole piece is within the incident path of the deviation correction sensor 120. That is, when the deviation correction sensor 120 is located at the target position, the edge position of the battery pole piece is within the detection range of the deviation correction sensor 120. Further, if at the position where the deviation correction sensor 120 arrives after moving, the edge position of the battery pole piece is not within the detection range of the deviation correction sensor 120, it means that this position is not the target position, and then the moving distance and moving direction of the deviation correction sensor 120 need to be adjusted again.

[0057] In one embodiment, the controller 140 is connected to the deviation correction sensor 120; further, the deviation correction sensor 120 is configured to measure the width of the battery pole piece after moving; the controller 140 is further configured to receive the measurement value output by the deviation correction sensor 120, determine whether the measurement value is equal to a preset target value, and output a prompt signal when it is determined that the measurement value is not equal to the preset target value; the touch screen 130 is further configured to receive the sensor position adjustment value input by the user; the controller 140 is further configured to control the servo motor to move through the sensor position adjustment value, so that the servo motor drives the deviation correction sensor 120 to move at a second speed; wherein, the second speed is less than the first speed.

[0058] It can be understood that in this embodiment, when adjusting the position of the deviation correction sensor 120 (i.e., during the process of driving the deviation correction sensor 120 to move by the servo motor), to ensure the accuracy of the moving position of the deviation correction sensor 120, the deviation correction sensor 120 is operated to measure the battery pole piece after the model change, so as to determine whether the current position of the deviation correction sensor 120 is the target position. That is, by operating the deviation correction sensor 120 and measuring the position information of the battery pole piece to verify whether the current position where the deviation correction sensor 120 is located meets the requirements. If not, one or more fine-tuning operations can be continued until it is determined that the position where the deviation correction sensor 120 is located is the target position.

[0059] This also means that during the movement of the deviation correction sensor 120, the position of the deviation correction sensor 120 can be detected in real time, so as to perform real-time adjustment to ensure the accuracy of the moving position of the deviation correction sensor 120, thereby improving the reliability and accuracy of subsequent monitoring of the battery pole piece. And, the value of each fine-tuning required for the deviation correction sensor 120 can be determined by the user's independent input, improving the flexibility of the fine-tuning of the deviation correction sensor 120. In addition, the value of each fine-tuning required for the deviation correction sensor 120 can also be automatically calculated by the controller 140 and adjusted synchronously, improving the efficiency of the fine-tuning of the deviation correction sensor 120.

[0060] It can be understood that as Figure 2During the process of unwinding the battery electrode sheet by the winding machine 200 shown, the electrode sheet roll is unwound through the unwinding shaft, and the unwound battery electrode sheet passes through multiple roller components 210. Among them, one or more deviation rectifying sensors 120 can be arranged between every two adjacent roller components 210, so as to detect whether the position deviation occurs during the unwinding process of the electrode sheet through the deviation rectifying sensor 120, and then realize the real-time monitoring and deviation rectification of the battery electrode sheet during the unwinding process.

[0061] Through the deviation rectifying device 100 provided by this embodiment, the user only needs to input the width information of the battery electrode sheet to be changed through the touch screen 130 into the controller 140. The controller 140 can automatically calculate the distance and direction that the deviation rectifying sensor 120 needs to move, and automatically control the servo motor to drive the deviation rectifying sensor 120 to move to the target position, which simplifies the adjustment process of the deviation rectifying sensor 120, avoids the synchronous change of the deviation rectifying sensor 120 along with the battery electrode sheet, reduces the operation difficulty in the actual scenario, makes the process of changing the battery electrode sheet easier to master and execute, and can flexibly adjust the position of the deviation rectifying sensor 120 with less manual intervention to ensure the reliability and accuracy of the monitoring and deviation rectification of the battery electrode sheet before and after the change.

[0062] Based on this, the present utility model further provides a deviation rectifying sensor changeover system, wherein, as Figure 3 shown, the system includes a deviation rectifying device 100 and a winding machine 200; the deviation rectifying device 100 corresponds to the aforementioned deviation rectifying device 100. Therefore, any optional item in the foregoing embodiment is applicable to this embodiment, so it will not be elaborated here.

[0063] Exemplarily, the deviation rectifying device 100 is placed in the unwinding area and / or the winding area of the winding machine 200. Optionally, multiple deviation rectifying devices 100 can be included in the unwinding area, and multiple deviation rectifying devices 100 can also be included in the winding area. The deviation rectifying device 100 is used for real-time monitoring and deviation rectification of the battery electrode sheet wound or unwound in the winding machine 200.

[0064] Furthermore, an unwinding component is arranged in the unwinding area of the winding machine 200, and a winding component is arranged in the winding area; optionally, both the unwinding component and the winding component include multiple roller components 210; among them, at least one deviation rectifying sensor 120 in the deviation rectifying device 100 is arranged between any two adjacent roller components 210 of the unwinding component and / or the winding component, and each deviation rectifying sensor 120 is arranged inside the roller component 210.

[0065] It can be understood that with reference to Figure 2, one or more deviation sensors 120 may be provided between any two adjacent roller components 210. Moreover, each deviation sensor 120 is disposed inside the roller component 210 and connected to the surface of the fuselage of the winding machine 200. Additionally, each deviation sensor 120 can be connected to a controller 140 simultaneously, that is, one controller 140 can synchronously control and monitor multiple deviation sensors 120, thereby realizing the synchronous movement control of multiple deviation sensors 120.

[0066] Optionally, each motor assembly 110 corresponds to a deviation sensor 120. Furthermore, each servo motor drives a deviation sensor 120 to move correspondingly, so as to facilitate the control of the movement process of each deviation sensor 120.

[0067] In this embodiment, the deviation correction device 100 is used to determine the target positions to which each deviation sensor 120 needs to move currently according to the width of the battery electrode sheet received by the user input after the battery cell type is changed, so as to control the corresponding servo motor to move, so that each servo motor drives the corresponding deviation sensor 120 to move to the corresponding target position at the first speed.

[0068] It can be understood that the deviation sensor type-changing system provided in this embodiment controls the movement state of the deviation sensor 120 through the servo motor. Furthermore, when the width of the battery electrode sheet changes, only the width after the type change needs to be input, and then the controller 140 can quickly calculate the target position to which the deviation sensor 120 needs to move and make it move to this target position, so as to ensure that the deviation sensor 120 can perform real-time monitoring and deviation correction on the battery electrode sheet after the type change, realizing rapid and accurate one-key type change.

[0069] In all the examples shown and described here, any specific value should be construed as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0070] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
