[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0028] The following combination Figures 1 to 3 , describing the embodiments of the present application.

[0029] According to an embodiment of the present application, on the one hand, a laser cleaning device is provided, including a mounting frame 1, an image recognition device 2, a laser 3, a driving mechanism 4 and a controller.

[0030] Specifically, the image recognition device 2 is installed on the mounting frame 1, and the image recognition device 2 is used to collect the distribution image of the residue on the surface of the pressure roller of the roller press; the laser 3 is slidably connected to the mounting frame 1, and the sliding direction of the laser 3 is parallel to the axial direction of the pressure roller, and the laser 3 is used to melt the residue; the driving mechanism 4 is installed on the mounting frame 1, and the driving mechanism 4 drives the laser 3 to slide through the transmission assembly 5; the controller is respectively communicated with the image recognition device 2, the laser 3 and the driving mechanism 4, and the controller obtains the distribution image of the residue, and controls the driving mechanism 4 and the laser 3 to clean the residue on the surface of the pressure roller according to the residue distribution image.

[0031] Before cleaning the surface of the roller of the roller press, the image recognition device 2 of the laser cleaning device of the present application is used to collect images of the surface of the roller of the roller press, generate a distribution image of the residue, and transmit the distribution image information of the residue to the controller. The controller analyzes and processes the image information, obtains the position information and volume information of the residue, and calculates the cleaning position of the laser 3 based on the position information of the residue. Then, the controller controls the drive mechanism 4 to start, and the drive mechanism 4 drives the laser 3 to reach the cleaning position, adjusts the power emitted by the laser 3, and the laser 3 emits a laser, which melts and removes the corresponding residue. The laser can accurately remove the residue and remove it cleanly with good effect, while improving the cleaning efficiency. The sliding direction of the laser 3 is parallel to the axial direction of the roller, which can ensure that the distance between its emission end and the surface of the roller is always equal during the sliding process of the laser 3. Therefore, the laser 3 does not need to frequently change the focal length when removing the residue on the surface of the roller, thereby improving the residue removal efficiency. The degree of automation is high and no manual intervention is required.

[0032] Specifically, the laser light emitted by the laser 3 is perpendicular to the longitudinal section of the pressing roller.

[0033] Specifically, the laser 3 may be a pulsed laser. The pulsed laser has the characteristics of high energy and high repetition frequency, so it can effectively remove residues and achieve good cleaning effects.

[0034] Specifically, the image recognition device 2 is an image acquisition camera, which uses a high-resolution lens to obtain clearer images.

[0035] In one embodiment, Figure 1 and Figure 2As shown, it also includes a guide rod 6, which is fixed on the mounting frame 1. The guide rod 6 is parallel to the axial direction of the pressure roller, and the laser 3 is slidably connected to the guide rod 6. The laser 3 is slidably connected to the mounting frame 1 through the guide rod 6, and the structure is simpler.

[0036] In one embodiment, Figure 1 and Figure 2 As shown, the apparatus further includes a slider 7. The slider 7 has a through hole corresponding to the guide rod 6. The through hole is slidably connected to the guide rod 6. The laser 3 is fixedly connected to the slider 7. The drive mechanism 4 drives the slider 7 to slide through the transmission assembly 5. The through hole is slidably connected to the guide rod 6, thereby making the slider 7 slidably connected to the guide rod 6. The laser 3 slides along the guide rod 6 with the slider 7. The drive mechanism 4 drives the slider 7 to move through the transmission assembly 5, facilitating the transport of the laser 3 to the cleaning position.

[0037] It should be further explained that the cross section of the guide rod 6 can be square, triangular, elliptical, etc., and the shape of the through hole matches the cross section of the guide rod 6 .

[0038] In one embodiment, Figure 1 and Figure 2 As shown, the transmission assembly 5 includes a screw, and the drive mechanism 4 is a drive motor. One end of the screw is in driving connection with the output shaft of the drive motor. The slider 7 has a threaded hole, into which the screw is threadedly engaged. The screw is arranged parallel to the guide rod 6. The drive motor rotates the screw, which is threadedly engaged with the threaded hole in the slider 7. The rotation of the screw drives the slider 7 along the guide rod 6. The transmission between the screw and the threaded hole improves the accuracy of the slider 7's movement, thereby improving the alignment accuracy between the laser and the residue on the roller surface.

[0039] In one embodiment, Figure 1 and Figure 2 As shown, the transmission assembly 5 further includes a coupling 8, which is used to connect the screw and the output shaft of the drive motor.

[0040] In one embodiment, a cleaning roller is further included. The cleaning roller is rotatably connected to the mounting frame 1. The laser 3 and the cleaning roller are arranged in sequence along the rotation direction of the pressure roller. The cleaning roller is used to clean the pressure roller. Residue on the surface of the pressure roller is melted after being irradiated by the laser. The cleaning roller rolls against the pressure roller to clean the surface of the pressure roller.

[0041] In one embodiment, the drive mechanism 4 is a servo motor. This motor can precisely control its position, speed, and acceleration. It also has a fast response speed, enabling rapid start, stop, and reverse rotation, adapting to high-speed motion and frequent starts and stops. The dynamic response time for acceleration and deceleration is short, typically within tens of milliseconds, enabling rapid response to control commands and enabling the laser 3 to quickly reach the cleaning position as the pressure roller rotates.

[0042] In one embodiment, Figure 1 and Figure 2 As shown, the mounting frame 1 is a U-shaped frame, with both ends of the U-shaped frame connected to the roller press. The image recognition device 2 is installed in the middle of the U-shaped frame. The ends of the U-shaped frame are connected to the roller press, leaving a certain gap in the middle of the U-shaped frame. The image recognition device 2 is installed on the U-shaped frame. The image recognition device 2 can fully identify one side of the roller and collect the distribution image of the residue on the roller surface, preventing blind spots in image information collection.

[0043] According to an embodiment of the present application, on the other hand, a roller press is also provided, including a frame 9, a first pressure roller 10, a second pressure roller 11, a pressure roller motor and two laser cleaning devices, the first pressure roller 10 and the second pressure roller 11 are rotatably connected to the frame 9, an extrusion gap is formed between the first pressure roller 10 and the second pressure roller 11, the pressure roller motor is installed on the frame 9 and is transmission-connected to the first pressure roller 10 and the second pressure roller 11 through a gear set, two mounting frames 1 are installed on the frame 9, two image recognition devices 2 are respectively arranged corresponding to the first pressure roller 10 and the second pressure roller 11, and two lasers 3 are respectively arranged corresponding to the first pressure roller 10 and the second pressure roller 11.

[0044] Among them, the gear set includes a first gear, a second gear and a third gear. The first gear and the second gear are respectively installed on the first pressure roller 10 and the second pressure roller 11, and the third gear is installed on the pressure roller motor. The first gear is engaged with the second gear, and the third gear is engaged with the first gear or the second gear.

[0045] Below is an embodiment, combined with Figures 1 to 3 A comprehensive explanation of all the above plans is given.

[0046] The roller motor drives the first and second rollers 10, 11 through a gear train. The first and second rollers 10, 11 rotate in opposite directions. The battery material passes through the extrusion gap and is pressed into shape. Some battery material may adhere to the first or second rollers 10, 11. Taking the cleaning of the first roller 10 as an example, the image recognition device 2 captures an image of the surface of the first roller 10, generates a distribution image of the residue, and transmits this image information to the controller. The controller analyzes and processes the image information using image processing algorithms such as edge detection and threshold segmentation to quickly and accurately identify the location and size of the residue. Based on this residue location information, the controller calculates the cleaning position of the laser 3. The servo motor is then activated. The servo motor's output shaft rotates the screw through the coupling 8, driving the slider 7 along the guide rod 6, causing the laser 3 to reach the cleaning position. The laser 3 then emits a laser beam, which melts and removes the corresponding residue. Subsequently, the cleaning roller cleans the surface of the first roller 10, further improving the cleaning effect.

[0047] According to an embodiment of the present application, on the other hand, a battery production line is provided, including a roller press.

[0048] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the accompanying application.
