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.

Embodiment Construction

[0022] Attached below Figure 1-3 The present invention is further described with the specific embodiment to further illustrate the automatic detection method for the length of the refill tail oil.

[0023] like figure 2 As shown, the detection device involved in this method includes a data transmission line 1 , a light source 2 , an industrial computer 3 , an image acquisition device 4 , a bracket 5 and a pen core transmission device 6 for transmitting the detected pen core 7 .

[0024] The refill transmission device (conveyor belt) 6 is signal-connected to the image capture device 4 , and starts the shooting action of the image capture device 4 when the refill transmission device 6 generates a transmission trigger signal to speed up the shooting efficiency.

[0025] The image acquisition device 4 is set as a grayscale image acquisition device, including a CCD camera and a lens. The image acquisition device 4 is provided with a lens with a focal length of 16 mm, or a lens w...

Abstract

The invention relates to a method and system for automatic detection of the length of pen refills and tails in the field of stationery manufacturing and detection. The method includes the following steps: sequentially fixing the image acquisition device and the position of the light source; collecting picture information; Refer to the sample refill to set the standard tail oil length range. If the length is within the valid range, it will output a logical value of "1". If the length is not within the range, it will output a logical value of "0". If no image is detected, it will output an "invalid" value. Then keep the refill whose output logic result is "1", and remove the refill whose output logic result is "0". Using this method, the detection accuracy and detection efficiency can be significantly improved.

Description

technical field [0001] The invention relates to the field of stationery manufacture and detection, in particular to an automatic detection method and system for the length of a pen refill tail oil. Background technique [0002] Roller ball pens, or neutral ink ballpoint pen, is 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. Gel pens have the advantages of both water pens and oil-based ballpoint pens, with comfortable writing feel, low ink viscosity, and the addition of substances that are easy to lubricate. The viscosity of the writing medium is between water-based and oil-based, so it is smoother than ordinary oil-based ballpoint pens. It is an upgraded product of oil-based ballpoint pens. [0003] In the production of gel pens, the injection of tail oil is one of the necessary processes. Whether the length of the tail oil is qualified is directly related to the safety ...
