Description

technical field [0001] The invention relates to the field of laser measurement, in particular to a method and device for measuring the transmission position of an amorphous strip. Background technique [0002] Amorphous alloy strips are widely used in the rolling of three-dimensional wound iron cores of distribution transformers because of their excellent properties such as uniform material, high stability, good flexibility, high magnetic permeability and low loss, so that they can seamlessly connect gas Significantly reduced, the reluctance is greatly reduced, the no-load current loss is significantly reduced, and it has a good energy-saving effect. The production of amorphous three-dimensional winding transformer core requires that the amorphous strip should not be twisted, folded, or torn during transmission, and it should not be wound too tightly on the roller shaft during rolling, otherwise the lamination coefficient of the core will be reduced. Reduced, the size and q...

Problems solved by technology

The production of amorphous three-dimensional winding transformer core requires that the amorphous strip should not be twisted, folded, or torn during transmission, and it should not be wound too tightly on the roller shaft during rolling, otherwise the lamination coefficient of the core will be reduced. reduced, the size and quality of the core cannot be guaranteed

However, when the strip is transported in the curved cutting and three-dimensional winding unit, due to the error and vibration of the transmission equipment, the inconsistent speed coordination of the front and rear transmission rollers, and the thin, hard, brittle material properties of the amorphous strip and the uneven transmission tension Affected by other factors, the amorphous strip is easy to deviate from the production and processing center line during the transmission process, and because of its own certain width, it is prone to lateral distortion, which makes the vertical displacement between the left and right ends of the wide-band amorphous strip and the conveyor belt. , even if the strip completely leaves the conveyor belt device, and the surface is bent, it is easy to fold or tear when it enters the roll, which seriously affects the transmission speed and winding quality of the amorphous strip.
