[0002] Currently, in the amorphous ribbon industry, using a laser of a certain power to uniformly and equidistantly score the surface of the ribbon can reduce hysteresis loss or eddy current loss, release internal stress, and effectively improve the performance of the amorphous ribbon, while also facilitating subsequent processing. The depth, uniformity and density of the score distribution, and the shape of the score all directly affect the performance and quality of the amorphous ribbon. Therefore, to ensure the accuracy of the scoring operation, the laser must simultaneously guarantee both positional precision and working surface stability, i.e., ensuring the precise and stable position of the amorphous ribbon. Furthermore, considering the efficiency requirements of industrial production, amorphous ribbon scoring needs to be a continuous operation. Therefore, a dedicated scoring device for amorphous ribbons is needed that can operate continuously while ensuring scoring accuracy. Utility Model Content

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.
[0017] This invention provides a dedicated marking device for amorphous ribbon. Figure 1 This is a schematic diagram of a special scoring device for amorphous ribbon according to an embodiment of the present invention. (Reference) Figure 1 As shown, the device includes at least: a laser 6, which marks the amorphous ribbon; a metering roller 3, which is electrically connected to the laser 6 and is used to measure the running speed of the amorphous ribbon and provide the speed parameters to the laser 6; a correction mechanism 5, which corrects the position of the amorphous ribbon in the width direction; and a stabilizing plate 9, which is located below the laser 6. The amorphous ribbon is attached to the stabilizing plate 9, and the stabilizing plate 9 forms a stable ribbon surface in the length direction of the amorphous ribbon. The metering roller 3, the correction mechanism 5, and the stabilizing plate 9 are arranged sequentially along the running direction of the amorphous ribbon. The above technical solution uses a metering roller 3 to accurately measure the running speed of the strip and provides the speed parameters to the laser 6. This allows the laser to adjust the marking scanning speed and direction based on the speed parameters, ensuring the accuracy of the marking position on the amorphous strip. A correction mechanism 5 is used to correct the position of the amorphous strip in the width direction, further increasing the accuracy of the marking position. A stabilizing support plate 9 is placed below the laser 6, allowing the amorphous strip to adhere to it and form a stable strip surface along its length. This ensures a stable working surface for the laser 6, guaranteeing accuracy in marking position, density, and distribution uniformity, while also ensuring the accuracy of marking depth and shape.
[0018] In some embodiments, adjusting rollers are provided at both ends of the stabilizing support plate 9 to adjust the height of the amorphous strip. The adjusting rollers precisely control the strip height, ensuring a tight fit with the stabilizing support plate 9. During operation, the height of the amorphous strip may fluctuate due to tension fluctuations throughout the device and variations in the strip's flatness. The adjusting rollers precisely control the height of the strip before it enters the stabilizing support plate 9, ensuring the strip adheres to the surface of the stabilizing support plate 9 with a preset pressure, preventing gaps or suspension between the strip and the support plate. Furthermore, the adjusting rollers eliminate surface undulations caused by tension fluctuations. The two adjusting rollers work together to apply a stable pre-pressure to the strip, maintaining a constant tension on the stabilizing support plate 9 and preventing laser focus shift due to surface undulations, which could result in marks that are too shallow or too deep. On the other hand, setting adjustment rollers can guide the strip to transition smoothly and reduce mechanical impact. If adjustment rollers are not set, the strip may wrinkle due to a hard transition when it enters the pallet. When the strip leaves the pallet, if the edge comes into contact with the edge of the pallet, it may cause surface scratches due to friction. Scratches on the surface of amorphous strip will reduce magnetic properties and affect the quality of the final product.
[0019] In some embodiments, the correction mechanism 5 includes multiple correction rollers and position sensors. The position sensors detect the position of the amorphous strip, and the correction rollers adjust the position of the amorphous strip. The position sensors convert the positional offset of the amorphous strip into an electrical signal, which is transmitted to the control system of the correction rollers. The control system controls the correction rollers to correct the position according to the positional offset of the strip. By setting the correction mechanism 5, the positional offset in the width direction caused by various factors during the operation of the amorphous strip is eliminated, such as the strip edge deviating from the preset path or the whole strip tilting to one side, ensuring that the strip always passes through the laser 6 marking area at a preset reference position. Moreover, the correction mechanism 5 can work in conjunction with the metering roller 3 and the stabilizing plate 9. The metering roller 3 ensures the speed stability in the length direction of the strip, and the correction mechanism 5 ensures the positional stability in the width direction. The combination of the two achieves two-dimensional precise positioning of the strip, providing a coordinate reference for the marking. In addition, the stabilizing plate 9 ensures the flatness of the strip and avoids distortion of the strip marking shape or error in the strip marking depth.
[0020] In some embodiments, the alignment rollers include a first roller, a second roller, a third roller, and a fourth roller, arranged sequentially along the amorphous ribbon's forward direction. The first and fourth rollers are at the same height, while the second and third rollers are at the same height but higher than the first and fourth rollers. The amorphous ribbon passes over the first, second, third, and fourth rollers sequentially. After passing under the first roller, the amorphous ribbon passes over the second roller above it, then over the third roller above it, and finally passes under the fourth roller. The second and third rollers provide alignment through oscillation, while the first and fourth rollers provide fixation and assist in alignment. This ribbon-threading method allows the amorphous ribbon to pass through multiple alignment rollers for alignment, ensuring accurate positioning of the amorphous ribbon in the width direction while maintaining appropriate tension.
[0021] In some embodiments, the device further includes: a feeding shaft 1 for mounting and feeding the amorphous strip master roll; and a take-up shaft 8 for winding and taking the amorphous strip. The feeding shaft 1 and the take-up shaft 8 are controlled to rotate by a motor. On the one hand, this arrangement allows the scoring device to operate continuously; on the other hand, the coordinated control of the feeding and winding speeds between the feeding shaft 1 and the take-up shaft 8 enables the establishment of stable tension, ensuring that the strip between the feeding and take-up shafts remains continuously and stably tensioned.
[0022] In some embodiments, the system further includes: a feeding stabilizing roller 2, positioned before the metering roller 3 along the running direction of the amorphous ribbon; and a corner roller 4, positioned after the metering roller 3 along the running direction of the amorphous ribbon. The feeding stabilizing roller 2 and the corner roller 4 are located on the same horizontal plane, with the metering roller 3 positioned higher than both the feeding stabilizing roller 2 and the corner roller 4. The amorphous ribbon passes over the feeding stabilizing roller 2, the metering roller 3, and the corner roller 4 in sequence. The corner roller controls the guidance and tension of the amorphous ribbon by adjusting the contact angle between the amorphous ribbon and the roller surface. The ribbon passing over the feeding stabilizing roller 2 from below, then over the metering roller 3 from above, and finally over the corner roller 4 from below effectively increases the wrap angle of the amorphous ribbon on the metering roller 3, increases friction to prevent slippage of the metering roller 3, and ensures metering accuracy.
[0023] In some embodiments, the bottom edge of the metering roller 3 is higher than the upper edge of the feeding stabilizing roller 2 and the wrapping roller 4, and the wrapping angle of the metering roller is ≥240°.
[0024] In some embodiments, a take-up stabilizing roller 7 is also provided between the stabilizing tray 9 and the take-up shaft 8; after the amorphous ribbon is laser-marked, it passes through the take-up stabilizing roller 7 and is wound up and collected by the take-up shaft 8.
[0025] In some embodiments, the laser 6 is configured as one or more. A single laser 6 is the basic configuration; multiple lasers 6 can improve production efficiency, match high-speed running strips, achieve complex scoring patterns, expand process flexibility, provide redundancy, and enhance equipment reliability.
[0026] In some embodiments, the stabilizing plate 9 is made of a high-temperature resistant material and has a smooth surface to prevent scratching the amorphous ribbon.
[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
