Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a material strip rolling device. Background Technology

[0002] Currently, in the manufacturing process of cylindrical batteries, the rolling process requires compacting the material strip, which necessitates extending the tabs beforehand. However, due to the influence of deviation correction, the extended portion of the tabs is prone to misalignment. This misalignment causes the extended position on the roller surface to not match the tab position, resulting in a wavy edge. In subsequent laser die-cutting processes, the tab edge cannot be accurately cut, thus affecting the overall quality and performance of the battery. Utility Model Content

[0003] To address the technical problem that the extension part of the electrode tab is prone to displacement in existing technologies, affecting the overall quality and performance of the battery, this utility model provides a strip rolling device. The device monitors the position of the electrode tab in real time through a camera and drives a servo motor to dynamically adjust the displacement of the extension roller, ensuring precise alignment of the extension part, effectively avoiding the generation of broken edges, and improving cutting accuracy and battery quality.

[0004] This utility model provides a strip pressing device, including a pressure roller and an extension roller. The pressure roller is located above the extension roller, and the pressure roller and the extension roller cooperate to extend the strip between them. A protrusion is provided in the circumferential direction in the middle of the extension roller. The extension roller is connected to a bearing seat, and a support seat is fixedly connected to the bearing seat. A drive assembly is connected to the support seat. A camera is provided obliquely below the extension roller to capture images of the extension roller and the area below the strip. The camera is connected to a controller, and the controller is connected to the drive assembly to control the drive assembly to push the support seat to move along the axial direction of the extension roller.

[0005] Furthermore, the drive components include servo motors.

[0006] Furthermore, the camera is a CCD camera. When the material strip deviates in position, the CCD camera transmits a PLC signal to the controller, and the controller controls the drive components to operate.

[0007] Furthermore, the bearing housing and the support housing are fixedly connected by screws.

[0008] Furthermore, one end of the stretching roller is connected to a first bearing seat, the first bearing seat is fixedly connected to a first support seat, and the first support seat is connected to a first drive assembly; the other end of the stretching roller is connected to a second bearing seat, the second bearing seat is fixedly connected to a second support seat, and the second support seat is connected to a second drive assembly. Both the first drive assembly and the second drive assembly are connected to the controller.

[0009] The beneficial effects of this utility model are as follows: This invention uses a camera to monitor the position of the tabs in real time and drives a servo motor to dynamically adjust the displacement of the extension roller, ensuring precise alignment of the extension area, effectively avoiding wavy edges, and improving cutting accuracy and battery quality. This invention also reduces electrode waste caused by unextended tabs and wavy material areas due to misalignment, reducing production losses, improving material utilization, optimizing the battery manufacturing process, and ensuring stable product quality. Furthermore, this invention uses pressure rollers and extension rollers to extend the material strip. The extension rollers are equipped with protrusions to extend the tab area, achieving uniform extension of the tabs and improving the degree of extension in the tab area, thus improving production quality.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0013] like Figure 1 and Figure 2As shown, this utility model provides a material strip 3 roller pressing device, including a pressure roller 1 and an extension roller 2. The pressure roller 1 is located above the extension roller 2 and the pressure roller 1 and the extension roller 2 cooperate to extend the material strip 3 between them. The material strip 3 is located between the pressure roller 1 and the extension roller 2, with the pressure roller 1 on top and the extension roller 2 on the bottom, to extend the material strip 3. A protrusion 4 is provided in the circumferential direction in the middle of the extension roller 2. The protrusion 4 extends the tab area. The thickness of the coating area in the material strip 3 is greater than that of the tab area. The radial dimension of the protrusion 4 is larger than the dimensions of other parts of the extension roller 2, and it contacts and extends the tab in the material strip 3 to achieve uniform extension of the tab.

[0014] like Figure 1 and Figure 2 As shown, the stretching roller 2 is connected to a bearing seat, which is fixedly connected to a support seat by screws. The support seat is connected to a drive assembly. A CCD camera 7 is positioned diagonally below the stretching roller 2 to capture images of the stretching roller 2 and the material strip 3 below. The CCD camera 7 is connected to a controller, which is connected to the drive assembly to control the drive assembly to push the support seat to move along the axial direction of the stretching roller 2. During the conveying of the material strip 3 between the pressure roller 1 and the stretching roller 2, the CCD camera 7 captures images of the tabs in real time. If there is any offset, a PLC signal is sent, and the CCD software accurately calculates the position of the tabs using image processing algorithms. The servo motor 8 dynamically adjusts the displacement of the stretching roller 2 based on the data to ensure precise alignment between the tabs and the stretching roller 2. If there is no offset, there is no action. The support base is driven to move by a drive assembly, the power of which is provided by a servo motor 8. In one embodiment, the servo motor 8 drives the lead screw to rotate, the nut moves linearly along the thread, and the nut moves along the axial direction of the lead screw, thereby driving the drive plate to push or pull the support base to move. Alternatively, in another embodiment, the servo motor 8 drives the nut to rotate, causing the screw to move along its axial direction, and the screw pushes or pulls the support base to move along the axial direction of the screw.
