Embodiment Construction

[0015] Embodiments of the needle processing device based on double detection of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Needle is an important tool used in sewing, and it needs to be inspected intensively. However, the current machine needle detection technology mainly analyzes the whole machine needle, and the degree of refinement of the detection is not enough. At the same time, it is difficult to choose the threshold value for the needle segmentation in the detection scheme based on image analysis, resulting in low needle detection accuracy. .

[0017] In order to overcome the above-mentioned shortcomings, the present invention builds a machine needle processing device based on double detection. For the same machine needle, the double flaw detection of the needle tip and the needle handle is carried out successively. More importantly, an adaptive image segmentation threshold is adopted to The needle to b...

Abstract

The invention relates to a textile needle treatment method based on double detection. The method includes: 1, providing a needle treatment apparatus based on double detection that comprises a stem detector, a tip detector and an embedded treatment device, wherein for a same needle, the tip detector detects whether a tip is flawed or not, the stem detector then detects whether a stem is flawed or not, the embedded treatment device is connected independently with the tip detector and the stem detector, and whether the needle under detection is removed or not is determined according to detection results of the tip detector and stem detector; 2, using the needle treating apparatus to carry out treatment. By using the method, needles that have a flawed tip or stem can be accurately removed in real time, and quality of finished needles is guaranteed.

Description

technical field [0001] The invention relates to the field of finished product quality detection, in particular to a method for processing textile machine needles based on double detection. Background technique [0002] In the prior art, the defect detection of machine needles is mainly through the image acquisition of the entire machine needle shape, the needles in the collected needle image are separated from the background, and the separated image is compared with the reference needle image , to determine if a defect exists. The above-mentioned solution can determine the overall defect of some machine needles to a certain extent. [0003] However, since the machine needle has two parts, the needle tip and the needle handle, there are certain differences in the external features of the needle tip and the needle handle. Partial characteristics cause deviations. [0004] For this reason, the present invention proposes a textile machine needle processing method based on dou...
