Detection method for continuous punching of steel band

Abstract

The invention discloses a detection method for continuous punching of a steel band; the method comprises the steps of setting an image acquisition device above a steel band under punching to perform acquiring, and determining focal length and object distance between the image acquisition device and the upper surface of the steel band below; calibrating a pixel equivalent so that a quantitative correspondence between the actual size of the steel band and the number of pixels in a steel band surface image acquired by the image acquisition device is created through the pixel equivalent; when rolling of the steel band is paused, starting to acquire a surface image of the steel band under punching by the image acquisition device; recognizing, by an industrial personal computer, the acquired surface image of the steel band, and calculating a processing measured value of punching of the steel band. The surface image of the steel band under punching is acquired through image recognition, the processing measured value of punching is calculated through image recognition, automatic detection is achieved for the steel band under punching, and detection efficiency and detection accuracy are improved.

Description

technical field [0001] The invention relates to detection technology, in particular to a detection method for punching continuous processing of steel strips. Background technique [0002] The punched nickel-plated steel strip is a product obtained by punching holes on the surface of the cold-rolled white steel strip, and then performing electrochemical nickel plating. It has good electronic conductivity and corrosion resistance, high cost performance, suitable for large-scale continuous production, and is widely used as a current collector material for batteries. At present, it is mainly used in the fields of MH-Ni battery, nickel-cadmium battery for tools, sintered battery for military industry and battery plate manufacturing for rail transit. [0003] The punching (punching) process in the process of punching nickel-plated steel strip is a key link in product formation, and key technical indicators such as punching hole diameter, horizontal hole distance and longitudinal ...

AI Technical Summary

Problems solved by technology

The manual detection has the following defects: ①The detection efficiency is low and it is easy to miss; ②Because the punched steel strip is coiled and produced continuously, sampling cannot be carried out during the production process, so even if there is a production problem, the problem cannot be found in time, so manual The detection is difficult to match with the current punching steel strip processing and manufacturing process
