隨著醫療水準和醫療器械的不斷提高和更新， 一次性注射針以其方便、衛生的特點深受用戶的喜愛， 其需求量也迅速增大， 而針頭外觀的好壞直接影響到一次性注射針的品質。 所以為了減少不合格品的數量， 需要增加檢測工序。 手工外觀核對總和產品標記昂貴並且不可靠。 人工檢測單調工作容易思想開小差導致不良產品流出。 而自動化機器視覺檢測系統提供了解決這些問題的方案。
With the continuous improvement and renewal of medical level and medical devices, disposable syringe needles are loved by users for their convenience and hygiene characteristics. Their demand is also increasing rapidly. The appearance of needles directly affects the quality of disposable syringe needles. Therefore, in order to reduce the number of unqualified products, it is necessary to increase the testing process. Manual inspection and product marking are expensive and unreliable. Artificial detection of monotonous work is easy to open the mind and lead to the outflow of bad products. The automated machine vision system provides a solution to these problems.
一次性注射針的缺陷
Defects of disposable injection needle
一次性注射針可以分為針座和針頭兩個部分。 針座的缺陷對產品的品質影響可以不計。 而針頭就存在著兩種缺陷情況：首先針頭在製作過程中針尖部位可能會產生毛刺;其次針頭在自動裝配過程中可能會產生倒插現象(針尖部位被插入針座)。 影響針頭的幾個缺陷為：針尖毛刺、倒插。 其中倒插不僅會對產品的品質產生直接的影響，
Disposable syringe can be divided into two parts: needle and needle. The needle defect effects on the quality of the products can be neglected. The needle there are two kinds of defects in the production process: first the needle tip may produce burr; secondly the needle may produce reverse phenomenon in the automatic assembly process (the needle tip is inserted into the needle). Effect of several defects: needle tip burr, insert. The insert will not only have a direct impact on the quality of the product, but also seriously endanger people's lives.
機器視覺檢測實現一次性注射針的外觀缺陷的自動化檢測方案
Automatic inspection scheme for visual defect of disposable injection needle by machine vision inspection
工作原理：首先光纖傳感器感應到注射針， 然後觸發影像處理器拍攝圖片， 並進行圖像分析處理， 最後驅動剔除裝置。 考慮到現在的自動化生產需要， 目前的剔除方法則採用整排剔除， 如果需要更高的自動化水準， 可以為每個針座加裝吸盤。
Working principle: first, the fiber sensor senses the injection needle, then triggers the image processor to take pictures, and carries out image analysis and processing, and finally drives the elimination device. Considering the automation of production needs, the method of eliminating the entire row by culling, if need higher automation level, can be installed for each hub chuck.
注射針外觀視覺檢測系統優勢：
Advantages of visual inspection system for injection needle:
1.能線上完成物件的存在性檢測、模型比較、形狀檢驗、位置和方向識別、工件的測量。 檢測速度達到600-1500根/分鐘， 並裝由調節器可以根據現場生產需要來調節檢測傳送帶的速度。 能通過剔除裝置準確剔除檢測出的次品， 可以根據生產線上所需檢測的不同產品方便地調節視覺檢測裝置的高度。
1. can complete the object detection, model comparison, shape test, location and direction identification, and the measurement of the workpiece. The detection speed is up to 600-1500 per minute, and the regulator can adjust the speed of the conveyor belt according to the production needs of the field. We can eliminate the detected defective products accurately by eliminating the device, and we can adjust the height of the visual inspection device conveniently according to the different products that need to be detected on the production line.
2.機器視覺檢測設備為獨立系統， 可方便地接入或退出使用， 所需各種硬體、軟體由廠家提供， 系統安裝、維護、拆卸方便。
2. machine vision inspection device is an independent system. It can be easily access or exit. All kinds of hardware and software needed are provided by the manufacturer, which is convenient for system installation, maintenance and disassembly.
