[0051] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0052] In the description of the present application, "module" and "processor" may include hardware, software or a combination of the two. A module may include hardware circuits, various suitable sensors, communication ports, memory, and may also include software parts, such as program code, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware or a combination of the two. Non-temporary computer-readable storage media include any suitable medium that can store program code, such as a disk, a hard disk, an optical disk, a flash memory, a read-only memory, a random access memory, etc. The term "A and / or B" means all possible combinations of A and B, such as only A, only B or A and B. The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B" and may include only A, only B or A and B. The singular terms "one" and "the" may also include plural forms.

[0053] In the prior art, during the coating process, a camera is used to capture images of the front and back surfaces of the electrode after coating, and the images of the two surfaces are analyzed to obtain the position of the coating area on the electrode. When it is determined based on the position that the active materials coated on the front and back sides are not aligned, an alarm message is issued, and the production staff adjusts the position of the die head based on the alarm message and the image. However, manual adjustment can easily cause insufficient or excessive adjustment, which in turn leads to the technical problem of misalignment of double-sided coating.

[0054] Based on this, in order to solve the above technical problems, the present application provides a new double-sided coating alignment control method to achieve double-sided coating alignment.

[0055] Figure 1 A double-sided coating alignment control system is provided according to an embodiment of the present application, such as Figure 1 As shown, the system includes: a front camera 11, a back camera 12, a control system 13, a servo motor 14, and a die head 15.

[0056] Among them, the control system 13 obtains the distance and coating speed between the die 15 and the front camera 11, and obtains the die action adjustment time interval according to the distance and the coating speed. The control system 13 obtains the time. When the time reaches the die action adjustment time interval, the front camera 11 collects the image data of the first side of the electrode, and the back camera 12 collects the image data of the second side of the electrode, and sends the image data of the first side and the image data of the second side to the control system 13. The control system 13 sends a movement instruction to the servo motor 14, and the servo motor 14 moves according to the movement instruction, thereby driving the die 15 to move.

[0057] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0058] Figure 2 The following is a flow chart of a double-sided coating alignment control method according to an embodiment of the present application. Figure 2 As shown, specifically, the method includes:

[0059] Step S201: obtaining the distance between the die head and the detection device and the coating speed.

[0060] In this embodiment, the distance between the die head and the detection device is fixed, and the distance from the die head to the detection device can be measured by a length measuring tool.

[0061] Step S202: Obtaining a die head action adjustment time interval according to the spacing and coating speed.

[0062] In this embodiment, the ratio of the spacing to the coating speed is the die head action adjustment time interval.

[0063] Step S203: After determining that the die head action adjustment time interval has been reached, the first surface and the second surface of the electrode are inspected and processed to obtain inspection results.

[0064] In this embodiment, the coating effect needs to be continuously detected. After the die head is adjusted, the detection device detects the coated electrode after the die head action adjustment time interval to obtain the coating effect after the die head adjustment.

[0065] In this embodiment, after collecting the image of the coated electrode through the camera, since the color of the electrode is different from the color of the active material, the position of the active material in the electrode is obtained after grayscale processing of the image.

[0066] Step S204: adjusting the die head according to the detection result.

[0067] In this embodiment, the position of the active material on the first surface and the position of the active material on the second surface should be the same. When coating the first surface, the active material is required to remain in the middle of the electrode. When coating the second surface, if the active material on the second surface is not aligned with the active material at the same position on the first surface, the die head needs to be adjusted according to the position of the active material at the same position on the first surface.

[0068] In this embodiment, the distance between the die head and the detection device and the coating speed are obtained; the die head action adjustment time interval is obtained according to the distance and the coating speed; after determining that the die head action adjustment time interval has been reached, the first side and the second side of the electrode piece are inspected and processed to obtain a detection result; according to the detection result, the die head is adjusted. Compared with the prior art, manual adjustment is prone to cause insufficient adjustment or excessive adjustment, which in turn leads to misalignment of double-sided coating. In this application, after obtaining the distance between the die head and the detection device and the coating speed, the die head action adjustment time interval is obtained according to the distance and the coating speed, and after determining that the die head action adjustment time interval has been reached, the first side and the second side of the electrode piece are inspected and processed to obtain a detection result, and according to the detection result, the die head is adjusted to achieve that during the coating process, the active materials on both sides of the electrode piece are in an aligned state.

[0069] Figure 3 The flowchart of the second embodiment of the double-sided coating alignment control method provided in the present application is based on the above embodiment. Figure 3 As shown, specifically, a specific method of step S202 is:

[0070] Step S301: Obtaining the time interval according to the spacing and coating speed.

[0071] In this embodiment, the ratio of the pitch and the coating speed is the time interval.

[0072] Step S302: obtaining a die head action adjustment time interval according to the time interval and preset adjustment parameters.

[0073] In this embodiment, a large error may occur during measurement between the die head and the detection device, so the error needs to be adjusted. The product of the preset adjustment parameter and the time interval is the die head action adjustment time interval.

[0074] In this embodiment, the preset adjustment parameters are data obtained through experiments before coating.

[0075] In this embodiment, the time interval is obtained according to the spacing and the coating speed; the die head action adjustment time interval is obtained according to the time interval and the preset adjustment parameters, and the accurate die head action adjustment time interval is obtained to avoid premature detection or late detection, thereby improving the accuracy of coating adjustment and reducing coating errors.

[0076] Figure 4 The flowchart of the third embodiment of the double-sided coating alignment control method provided in the present application is based on the above embodiment. Figure 4 As shown, specifically, one implementation of step S204 includes:

[0077] Step S401: Determine that the detection result is that the first distance between the first side of the actual coating area on the first surface of the pole piece and the first side of the first surface of the pole piece is greater than the second distance between the first side of the actual coating area on the second surface of the pole piece and the first side of the second surface of the pole piece.

[0078] In this embodiment, if the first distance between the first side of the actual coating area on the first surface of the pole piece and the first side of the first surface of the pole piece is greater than the second distance between the first side of the actual coating area on the second surface of the pole piece and the first side of the second surface of the pole piece, the actual coating area on the second surface is biased toward the first side relative to the actual coating area on the first surface.

[0079] Step S402: sending a first movement instruction to the die head so that the die head moves to the second side of the second surface.

[0080] In this embodiment, since the actual coating area of ​​the second surface is biased toward the first side relative to the actual coating area of ​​the first surface, the die head needs to be moved toward the second side, and the moving length is the difference between the first distance and the second distance.

[0081] In this embodiment, the die head is adjusted only when the difference between the first distance and the second distance is greater than 0.3 mm.

[0082] In this embodiment, the coating width remains unchanged, and only one side needs to be inspected.

[0083] In this embodiment, the detection result is determined to be that the first distance between the first side of the actual coating area on the first surface of the electrode and the first side of the first surface of the electrode is greater than the second distance between the first side of the actual coating area on the second surface of the electrode and the first side of the second surface of the electrode; a first movement instruction is sent to the die head to allow the die head to move to the second side of the second surface, so as to adjust the coating position of the second surface.

[0084] Figure 5 The flowchart of the third embodiment of the double-sided coating alignment control method provided in the present application is based on the above embodiment. Figure 5 Specifically, another implementation of step S204 includes:

[0085] Step S501: Determine that the detection result is that the first distance between the first side of the actual coating area on the first surface of the pole piece and the first side of the first surface of the pole piece is smaller than the second distance between the first side of the actual coating area on the second surface of the pole piece and the first side of the second surface of the pole piece.

[0086] In this embodiment, if the first distance between the first side of the actual coating area on the first surface of the pole piece and the first side of the first surface of the pole piece is smaller than the second distance between the first side of the actual coating area on the second surface of the pole piece and the first side of the second surface of the pole piece, the actual coating area on the second surface is biased toward the second side relative to the actual coating area on the first surface.

[0087] Step S502: Sending a second movement instruction to the die head so that the die head moves toward the first side of the second surface.

[0088] In this embodiment, since the actual coating area of ​​the second surface is biased toward the second side relative to the actual coating area of ​​the first surface, the die head needs to be moved toward the first side, and the moving length is the distance difference obtained by subtracting the first distance from the second distance.

[0089] In this embodiment, the detection result is determined to be that the first distance between the first side of the actual coating area on the first side of the pole piece and the first side of the first side of the pole piece is smaller than the second distance between the first side of the actual coating area on the second side of the pole piece and the first side of the second side of the pole piece; a second movement instruction is sent to the die head to enable the die head to move toward the first side of the second side, thereby adjusting the coating position of the second side.

[0090] Figure 6 The flowchart of the fifth embodiment of the double-sided coating alignment control method provided in the present application is based on the above embodiment. Figure 6 As shown, specifically, before step S201, the method includes:

[0091] Step S601: obtaining a preset coating width of the first surface and a width of the first surface of the electrode.

[0092] In this embodiment, before coating, a preset coating width needs to be set, and the preset coating width determines the width of the active material on the electrode.

[0093] Step S602: according to the preset coating width of the first surface and the width of the first surface of the pole piece, obtain the first width of the first side of the coating area of ​​the first surface of the pole piece and the first side of the first surface of the pole piece.

[0094] In this embodiment, the width of the first surface of the pole piece minus the preset coating width of the first surface obtains the sum of the widths of the coating area and the two sides of the pole piece. Ideally, the coating area is located in the middle of the pole piece. Therefore, half of the sum of the widths is the first width of the first side of the coating area on the first surface of the pole piece and the first side of the first surface of the pole piece.

[0095] Step S603: Obtain the second width of the first side of the actual coating area on the first surface and the first side of the first surface of the pole piece.

[0096] Step S604: if it is determined that the first width is greater than the second width, a third movement instruction is sent to the die head so that the die head moves toward the second side of the first surface of the pole piece.

[0097] In this embodiment, if it is determined that the first width is greater than the second width, it is determined that the actual coating area is biased toward the first side, and the model needs to be moved toward the second side, and the moving distance is the difference between the first width and the second width.

[0098] In this embodiment, the preset coating width of the first surface and the width of the first surface of the electrode are obtained; based on the preset coating width of the first surface and the width of the first surface of the electrode, the first side of the coating area of ​​the first surface of the electrode and the first side of the first surface of the electrode are obtained; the second width of the first side of the actual coating area of ​​the first surface and the first side of the first surface of the electrode are obtained; if it is determined that the first width is greater than the second width, a third movement instruction is sent to the die head for the die head to move to the second side of the first surface of the electrode piece, thereby ensuring that the active material is in the middle of the electrode piece when the first surface of the electrode piece is coated.

[0099] Figure 7 The flowchart of the sixth embodiment of the double-sided coating alignment control method provided in the present application is based on the above embodiment. Figure 7 As shown, specifically, after step S603, the method further includes:

[0100] Step S701: if it is determined that the first width is smaller than the second width, a fourth movement instruction is sent to the die head so that the die head moves toward the first side of the first surface of the pole piece.

[0101] In this embodiment, if it is determined that the first width is smaller than the second width, it is determined that the actual coating area is biased toward the second side, and the model needs to be moved toward the first side, and the moving distance is the difference between the second width and the first width.

[0102] In this embodiment, the preset coating width of the first surface and the width of the first surface of the electrode are obtained; based on the preset coating width of the first surface and the width of the first surface of the electrode, the first side of the coating area of ​​the first surface of the electrode and the first side of the first surface of the electrode are obtained; the second width of the first side of the actual coating area of ​​the first surface and the first side of the first surface of the electrode are obtained; if it is determined that the first width is less than the second width, a fourth movement instruction is sent to the die head so that the die head moves toward the first side of the first surface of the electrode piece, thereby ensuring that the active material is in the middle of the electrode piece when the first surface of the electrode piece is coated.

[0103] Figure 8 A schematic diagram of a double-sided coating alignment control method embodiment 7 provided in the present application is shown in FIG. Figure 8 As shown, after step S402, the method further includes:

[0104] Step S801: Obtain a distance difference according to the first distance and the second distance.

[0105] Step S802: If it is determined that the distance difference is greater than a preset distance threshold, an alarm message is sent to a maintenance personnel terminal.

[0106] In this embodiment, the preset distance threshold is the die adjustment distance. When the distance difference is greater than the die adjustment distance, the coating cannot be adjusted. At this time, a mechanical failure may occur and an alarm message needs to be sent to the maintenance personnel terminal. The maintenance personnel performs maintenance on the coating equipment based on the alarm message.

[0107] In this embodiment, a distance difference is obtained based on the first distance and the second distance; if it is determined that the distance difference is greater than a preset distance threshold, an alarm message is sent to the maintenance personnel terminal to improve the stability of the coating process.
