Device for rapidly detecting bunching head defects of steel wires

Abstract

The invention provides a device for rapidly detecting bunching head defects of steel wires. A first light source emitter is electrically connected with a first camera unit; a second light source emitter and a second camera unit are electrically connected with each other, and are placed according to a set position arrangement mode; the first camera unit acquires a first image forming an angle thetawith the X axis, transmits the first image to an image processing unit, and calculates cord fabric winding quality; the second camera unit collects a second image forming an angle alpha with the X axis, transmits the second image to a matrix black grid measurement unit, and calculates cord fabric winding quality; the detection unit receives images and results transmitted by the matrix black gridmeasurement unit and the image processing unit, analyzes the cord fabric winding quality at all angles of the bunching heads of steel wires, compares the cord fabric winding quality with set qualifiedparameters, and outputs a comparison result to a programmable logic controller. The device can achieve the independent online detection of the position of each bunching head, reduces errors, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a fast steel wire tie defect detection device. Background technique [0002] The quality of the steel wire tie head depends on the quality of the tie head winding. If the tie head is not well wound, the cord will be lifted, folded, the number of windings is too much or too little, the thread is not even, and the cord is missing. Therefore, its detection It is particularly important; in the traditional tie size measurement technology, the commonly used measuring tools are vernier calipers and cameras, which mainly measure geometric dimensions, tie thickness, material defects, etc., and these measurements involve more manual participation and are stable. The performance is not good, resulting in a large error between the measured value and the real value, resulting in low detection efficiency, so that the production cost of the enterprise will increase. In addition, usin...

Problems solved by technology

[0002] The quality of the steel wire tie head depends on the quality of the tie head winding. If the tie head is not well wound, the cord will be lifted, folded, too many or too few winding times, uneven threads, and even the cord will be missing. Therefore, its detection It is particularly important; in the traditional tie size measurement technology, the commonly used measuring tools are vernier calipers and cameras, which mainly measure geometric dimensions, tie thickness, material defects, etc., and these measurements involve more manual participation and are stable. The performance is not good, resulting in a large error between the measured value and the real value, resulting in low detection efficiency, so that the production cost of the enterprise will increase

In addition, using a backlight as a measurement light source will cause a large measurement error for accurate measurement
