Refill tail oil length automatic detection method and system

Abstract

The invention relates to a refill tail oil length automatic detection method and system in the field of stationery manufacturing and detection. The detection device involved in the method comprises adata transmission line, a light source, an industrial personal computer, an image acquisition device, a support and a refill transmission device used for transmitting a detected refill. The method comprises the following steps of: sequentially fixing the positions of the image acquisition device and the light source, collecting image information, processing the image information and performing binarization processing on the image through a grayscale image processing system, and outputting a result, setting a standard tail oil length range by referring to the sample refill, outputting a logic value '1' when the length is within an effective range, outputting a logic value '0' when the length is not within the range, outputting an 'invalid' value when the image is not detected, repeating thesteps, then retaining the refill with the output logic result '1', and removing the refill with the output logic result '0'. By using the method, the detection accuracy and the detection efficiency can be remarkably improved.

Description

Technical field [0001] The invention relates to the field of stationery manufacturing and detection, and in particular to a method and system for automatically detecting the length of pen core tail oil. Background technique [0002] Roller ball pens, or neutral ink ballpoint pens, are currently a popular writing tool in the world. According to the type of pen tip, ink color, structure, etc., it can be divided into different types of gel pens. The gel pen has the advantages of a fountain pen and an oil-based ballpoint pen. It has a comfortable writing feel, lower ink viscosity, and adds materials that are easy to lubricate. The viscosity of the writing medium is between water and oil, so it is smoother than ordinary oil-based ballpoint pens. It is an upgraded product of oily ballpoint pen. [0003] In the production of gel pens, the injection of tail oil is one of the necessary processes. The length of tail oil is directly related to the safety of the pen core. If the amount of t...

Problems solved by technology

However, the manual screening method has a large workload, low work efficiency and low accuracy, and the detection speed is difficult to meet the production requirements

Moreover, the existing detection methods still have problems such as fuzzy judgment standards, inaccurate detection due to observation angle, clarity and magnification, and low accuracy and low efficiency caused by human uncontrollable factors.
