Needle detection device and detection method thereof

Abstract

The invention discloses a needle detecting device; a waste elimination mechanism, a needle tube through-blocking detecting mechanism, a needle tube total length inspection mechanism, an edge inspection mechanism and a needle detecting and guiding positioning block are respectively and sequentially arranged on the outer side of a feeding turntable along the outer edge of the feeding turntable; the needle detecting device can realize full automatic detection function, the main inspection items include inspecting whether needle tube cutting edge parts have blunt trauma and burr, whether the needle tube is blocked and bent, whether the needle tube total length is oversize and the like, the needle detecting device can automatically feed a needle, automatically eliminate a needle, automatically draw back a needle, and is high in degree of automation, by the use of a high performance fiber optic sensor, high speed synchronous detection, data storage and data feedback can be realized, the whole device is reasonable in design, efficient in integration, high in detection precision, and stable in working state, has good practicability, can further improve the work efficiency, and avoids false detection and missing detection in detection links.

Description

technical field [0001] The invention relates to the technical field of medical needle detection equipment, in particular to a fully automatic intelligent needle detection device, in particular to its mechanical structure and detection method. Background technique [0002] Syringe needle tubes have high precision requirements. It is required that there should be no blunt wounds and burrs on the cutting edge, no blockage and bending in the needle tube, and no error in the total length of the needle tube. The traditional needle tube detection relies on manual detection, which is inefficient and takes a long time. Detection is prone to visual fatigue, which eventually leads to flaws in the detection process, and false detections and missed detections occur from time to time. [0003] The functions of the existing mechanical needle detection equipment are relatively single, and there are many problems in the overall design, which cannot realize automatic feeding, automatic pickin...
