[0024] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0026] For the flying cutting in the lithium battery winding machine, the cutting method has evolved from the previous fixed cutting method to a mechanical cam structure, and has now been further improved to an electronic cam method. However, in the existing electronic cam application solution, many parameters need to be modified according to different process parameter conditions, such as key point position, speed, acceleration and deceleration, Jerk value, etc., which is still inconvenient to use.

[0027] Based on this, the embodiment of the present application provides a fly-cut control system, such as Figure 1 As shown, the system includes a material length measuring encoder, a PLC (Programmable Logic Controller), a data processing, measurement and command control module, a flying cutting electronic cam control module, a main cam control module, a nested sub-cam control module, a flying cutting motor, a cutter motor and a cutter, wherein:

[0028] The fly-cut electronic cam control module is used to plan the main electronic cam control curve, the fly-cut electronic cam control curve and the cutter electronic cam control curve;

[0029] The cam control module uses the encoder axis as the main axis and the virtual axis as the slave axis, and works according to the planned main electronic cam control curve;

[0030] The nested sub-cam control module uses the virtual axis slave axis in the main cam as the main axis, and the fly-cut servo axis and the cutter servo axis as the slave axes;

[0031] The fly-cut motor is used to operate under the control of the fly-cut servo shaft;

[0032] The cutter motor is used to operate under the control of the cutter servo axis.

[0033] Based on the above-mentioned fly-cut control system, the present application embodiment provides a fly-cut control method, such as Figure 2 As shown, the method includes:

[0034] S201: Acquire a starting point of the slave axis and a cutting target position of the main axis, and determine a slave axis travel of the slave axis from the starting point to the cutting target position based on the starting point and the cutting target position;

[0035] In an embodiment of the present application, the cutting target position can be equal to the sum of the probe recording value and the distance from the sensor to the cutter, wherein the probe recording value refers to the position of the material length encoder when the sensor detects the pole piece mark position (such as a marking hole) using probe technology to record the position.

[0036] The starting point may be equal to the difference obtained by sequentially subtracting the deceleration zone distance, the synchronization zone distance and the acceleration catch-up zone distance from the cut-off target position.

[0037] like Figure 3 As shown, assuming that point S is the starting point of the slave axis and point D is the cutting target position of the main axis, then the slave axis stroke SL=DS.

[0038] S203: Acquire a master-slave axis position relationship curve, and determine a maximum slave axis stroke of the slave axis based on the master-slave axis position relationship curve;

[0039] In an embodiment of the present application, the main electronic cam control curve in the fly-cut control system may include three control curves: an acceleration catch-up section, a synchronization section, and a deceleration section. The master-slave shaft position relationship curve may refer to the control curve of the acceleration catch-up section. The master-slave shaft position relationship curve is used to characterize the relationship between the master shaft stroke and the slave shaft stroke in the acceleration catch-up section.

[0040] In an embodiment of the present application, the master-slave axis position relationship curve is an Nth-order polynomial function, where N≥3.

[0041] In the embodiments of the present application, Figure 4 As shown, the acquiring of the master-slave axis position relationship curve and determining the maximum slave axis stroke of the slave axis based on the master-slave axis position relationship curve may include:

[0042] S401: Obtaining a master-slave axis position relationship curve;

[0043] S403: Deriving the master-slave axis position relationship curve once, and setting the value of the expression to zero, to determine the slave axis stroke corresponding to the maximum position in the master-slave axis position relationship curve;

[0044] S405: Determine the slave axis stroke corresponding to the maximum position value as the maximum slave axis stroke of the slave axis.

[0045] In a specific embodiment, the master-slave axis position relationship curve is controlled by a 5th-order curve without overshoot. The first derivative of the 5th-order curve is calculated and the value of the expression is set to 0, and the maximum master axis stroke and the maximum slave axis stroke (X) corresponding to the maximum value of the 5th-order curve position can be calculated. max ,Y max ).

[0046] S205: When the slave axis stroke is less than or equal to the maximum slave axis stroke, determining the main axis stroke of the main axis based on the slave axis stroke and the main-slave axis position relationship curve;

[0047] In an embodiment of the present application, if the slave axis stroke is less than or equal to the maximum slave axis stroke, it indicates that there is no position overshoot in the control process, and the spindle stroke of the main axis is determined according to the slave axis stroke and the master-slave axis position relationship curve.

[0048] In an embodiment of the present application, the method may further include:

[0049] When the slave axis stroke is greater than the maximum slave axis stroke, updating the master-slave axis position relationship curve;

[0050] The main axis stroke of the main axis is determined based on the slave axis stroke and the updated master-slave axis position relationship curve.

[0051] In an embodiment of the present application, if the slave axis stroke is greater than the maximum slave axis stroke, it means that the position has overshot and the master axis stroke needs to be adjusted. At this time, the master-slave axis position relationship curve is replanned until the slave axis stroke is less than or equal to the maximum slave axis stroke.

[0052] S207: Determine a coupling starting point of the main shaft and the slave shaft based on the cut-off target position and the main shaft stroke.

[0053] In an embodiment of the present application, determining the coupling starting point of the main shaft and the slave shaft based on the cut-off target position and the main shaft stroke may include: determining the difference obtained by subtracting the main shaft stroke from the cut-off target position as the coupling starting point of the main shaft and the slave shaft.

[0054] like Figure 3 As shown in the figure, the spindle stroke SM = DM, so the coupling starting point M of the spindle and the slave axis = D-SM. Therefore, when the cut-off target point D changes, it is only necessary to automatically update the coupling starting point M without manually setting other related parameters. The cut-off target point D is the dividing point between the acceleration catch-up zone and the synchronization zone. After the pole piece is cut off, it enters the synchronization zone and the deceleration zone, and the slave axis follows the spindle to make a linear motion until the stop point E.

[0055] In the main cam control, linear control can meet the requirements for the synchronization section and the deceleration section.

[0056] In the embodiment of the present application, the entire main cam control process adopts a three-stage control method: namely, the acceleration and catching-up zone, the synchronization zone and the deceleration zone. The boundary conditions of each zone are automatically calculated. When the key point position change is detected, the cam table is automatically updated. There is no need for manual input of additional parameters. For example, only the upper and lower limit positions of the flying cutting axis and the cutting knife axis need to be manually confirmed. When the parameters are changed, the cam curve will be automatically planned and updated according to the initial position, realizing the input-free and automatic generation functions of the cam parameters, reducing the requirements for manual intervention of the parameters, and improving the intelligence of the equipment.

[0057] In addition, when the position curve between key points is set to a first-order or fifth-order curve, the main axis stroke and slave axis stroke will be automatically calculated according to the selected curve type, thereby limiting the position, speed, and acceleration values ​​during the movement between key points, avoiding sudden changes in position and acceleration, overshoot or reversal of speed, which may damage the equipment and affect product quality. The entire cam control process is smoother, safer, and more reliable.

[0058] The above is the whole process of main cam control in the fly-cut control system. At this time, the virtual axis serves as the slave axis of the main cam, while in the nested sub-cam control, the virtual axis serves as the master axis, and the slave axes are the fly-cut servo axis and the cutter servo axis.

[0059] Corresponding to the sub-cam control, point S corresponds to the starting point of the fly-cut servo axis, point D is the fly-cut clip position, and until the end point E, the slave axis is a straight line trajectory throughout the entire process.

[0060] As for the cutter servo axis, point S corresponds to the cutter opening position of the cutter servo axis, and the area between points D and E corresponds to the cutter cutting position of the cutter servo axis, that is, the pole piece can be cut within the synchronization zone and deceleration zone of the virtual axis (main axis). Similarly, in order to ensure the smoothness of the operation of the cutter servo axis, the movement process of the cutter servo axis from point S to point E is further divided into three control sections: acceleration and catching up section, synchronization section and deceleration section. The process is similar to the main cam control process, which will not be repeated here.

[0061] Through the fly-cut control method of the present application, it is possible to achieve the elimination of cam parameter input and realize high intelligence of the equipment; at the same time, smooth operation without overshoot of each fly-cut slave axis is achieved, thereby improving the smoothness and reliability of operation; thirdly, through the cam control of the fly-cut servo axis and the cutter servo axis, the operating time of the fly-cut process is significantly shortened and the working efficiency of the winding machine is improved.

[0062] In practical applications, the fly-cut control method of the embodiment of the present application can be applied not only to fly-cut control situations on winding machine equipment, but is also practical in multi-axis linkage control in other situations requiring high-efficiency follow-up cutting.

[0063] The present application also provides a fly-cut control device, such as Figure 5As shown, the device comprises:
