制藥廠商為了達到藥品的質量要求，結合機器視覺檢測系統及自動化生產線機器，通過圖形分析、顏色辨識、條形碼辨識以及字符檢測，以實現高質量及高效益的生產線流程。
In order to meet the quality requirements of drugs, pharmaceutical manufacturers, combined with machine vision detection system and automatic production line machines, through graphic analysis, color identification, bar code identification and character detection, to achieve high-quality and high-efficiency production line process.
近幾年，各地制藥廠商紛紛加入了全自動化生產線的行列。其中，液態藥瓶生產制造及檢測過程歷經層層關卡，借助機器視覺系統，總體檢測效率及檢測準確性都較以往的人力大幅提高。彩色工業相機，能夠在高速運轉的生產線上捕捉到每個經過藥瓶的圖像，然后經過后端圖像軟件分析，進行良品與不良品篩選，同時也可以記錄圖像數據，以便后序可以快速且準確地查詢、追溯和檢索品項。
In recent years, pharmaceutical manufacturers have joined the ranks of fully automated production lines. Among them, the manufacturing and testing process of liquid medicine bottle has gone through many levels of barriers. With the help of machine vision system, the overall detection efficiency and detection accuracy are greatly improved compared with the previous manpower. The color industrial camera can capture the image of each medicine bottle passing through the high-speed production line, and then through the analysis of the back-end image software, the good and bad products can be screened. At the same time, the image data can also be recorded, so that the subsequent order can quickly and accurately query, trace and retrieve the items.
瓶裝藥品檢測
Bottled drug testing
液態藥品裝瓶后，通常需要經過個檢測環節，來判斷藥液裝瓶是否夠量、瓶口是否有破損、瓶蓋是否壓裝到位，以確保藥量正確、藥瓶封裝完好，以及瓶內的真空度正常。因此，在對瓶裝藥液進行檢測前，制藥商通常會先利用圖像傳感器紀錄正常瓶口的特征和藥液的標準位置。當每瓶藥液經過檢測鏡頭前時，相機會捕捉當前被檢測物體的特征，然后將捕獲的圖像與先前拍攝的樣本圖像進行比對。檢測標準采用的是相對位置標準，因此并不會因瓶子在傳送帶上受到微弱跳動的影響而做出錯誤判斷。
After the liquid medicine is bottled, it usually needs to go through a test link to judge whether the liquid medicine is bottled enough, whether the bottle mouth is damaged, whether the bottle cap is pressed in place, so as to ensure that the drug quantity is correct, the medicine bottle is sealed well, and the vacuum degree in the bottle is normal. Therefore, before the detection of bottled liquid medicine, pharmaceutical manufacturers usually use image sensors to record the characteristics of the normal bottle mouth and the standard position of the liquid medicine. When each bottle of liquid medicine passes through the detection lens, the camera will capture the characteristics of the currently detected object, and then compare the captured image with the previous sample image. The detection standard adopts the relative position standard, so it will not make wrong judgment because the bottle is affected by the weak beating on the conveyor belt.
USB 工業相機在藥瓶檢測中的應用
Application of USB industrial camera in medicine bottle detection
USB工業相機現今已被廣泛安裝在機器輸送帶上，代替人眼進行判斷和測量，因為它能夠在高速移動過程中捕獲清晰的圖像，并能快速且準確地進行圖像數據的傳輸和處理。USB 3．1工業相機能在較為惡劣的環境下長時間連續運行，并能保證穩定、可靠的性能和準確的拍攝效率，可以用來監控、分析和優化制藥流程，確保藥品質量，提高生產率。
Nowadays, USB industrial camera has been widely installed on the conveyor belt instead of human eyes to judge and measure, because it can capture clear images in the process of high-speed movement, and can transfer and process image data quickly and accurately. USB 3.1 industrial camera can run continuously for a long time under harsh environment, and can ensure stable and reliable performance and accurate shooting efficiency. It can be used to monitor, analyze and optimize pharmaceutical process, ensure drug quality and improve productivity.
瓶口瑕疵或缺損
Bottle mouth defect or defect
空藥瓶在運送過程中難免會碰撞缺損，為避免瓶內有碎玻璃混進以及之后瓶蓋無法密合，在填裝藥液之前，可運用工業相機進行垂直進行瓶口檢測，首先篩選過濾有缺損或破碎瓶口的空藥瓶。感光元件，提供高畫速及低噪點圖像品質，可清楚呈現所拍攝之瓶口，幀速率達593幀／秒，可捕捉快速通過產線的每一個藥瓶，拍攝后的圖像則可即時傳送至小電腦，透過電腦自動比對正常樣本圖像之后，小電腦便可下指令至自動化機器，將不符合標準的藥瓶送入廢品區淘汰。
It is inevitable that the empty medicine bottle will collide and be damaged in the transportation process. In order to avoid the mixing of broken glass in the bottle and the failure of sealing the bottle cap, the industrial camera can be used for vertical detection of the bottle mouth before filling the liquid medicine. Firstly, the empty medicine bottle with defect or broken bottle mouth is screened and filtered. The photosensitive element provides high-speed and low-noise image quality, and can clearly present the captured bottle mouth. The frame rate is up to 593 frames / s, which can capture each medicine bottle passing through the production line quickly. The captured image can be immediately transmitted to a small computer. After the computer automatically compares the normal sample images, the small computer can send instructions to the automatic machine to send the unqualified medicine bottles The waste area will be eliminated.
瓶口封蓋及液體位置檢測
Bottle cap and liquid position detection
當藥瓶經過自動化機器填充完液體藥品后，便直接封口。一般醫療用藥液會有內塞先封住瓶口，接著再使用機器將外蓋內氣壓密合，以確保瓶內藥液不受污染或變質。先透過相機彩色工業相機垂直拍攝瓶蓋顏色，獲得的圖像傳輸至電腦，透過事先儲存設定的色彩，進行顏色比對，來辨識所經過的藥瓶是否正確。接著，在下一個關卡架設側拍相機，取得的圖像經過量測軟件或程序來辨別液位高度，同時上下比對瓶蓋位置，確認是否每個瓶蓋都已密封。在此兩關卡上，不合格的藥瓶則如瓶口檢測后的結果，由小計算機自動下指令至自動化機器，送至廢品區。
When the medicine bottle is filled with liquid medicine by automatic machine, it is sealed directly. In general, the bottle mouth is sealed with an inner plug, and then the air pressure inside the cover is sealed with a machine to ensure that the liquid medicine in the bottle is not polluted or deteriorated. First, the color of the bottle cap is photographed vertically by the color industrial camera of the camera, and the image is transmitted to the computer. By storing the set color in advance, the color comparison is carried out to identify whether the medicine bottle passed by is correct. Then, a side camera is set up at the next level, and the obtained image is identified by measuring software or program. At the same time, the position of bottle cap is compared up and down to confirm whether each cap is sealed. At these two levels, unqualified medicine bottles, such as the results of bottle mouth detection, are automatically sent to the automatic machine by the small computer and sent to the waste area.
貼標／標碼檢測及字符辨識
Label / code detection and character recognition
而除了藥瓶檢測，許多制藥商會在藥瓶瓶身或瓶蓋上貼上或嵌入卷標號碼、日期或相關的藥品名稱。映美精相機提供高效穩健的條形碼辨識算法，能迅速地偵測并辨識任何方位的一維與二維條形碼；也可以設定只掃描特定的條形碼圖形及方位；或設定感興趣區域ROI，以加速偵測及解碼效率。制藥廠商只需要利用工業相機讀取標簽上或噴涂在包裝上的一維或二維條形碼，就可以實時獲得藥品的詳細成分、生產日期、批號和有效日期等相關信息。
In addition to bottle testing, many pharmacists attach or embed the label number, date or related drug name on the bottle body or cap. Yingmei precision camera provides an efficient and robust barcode identification algorithm, which can quickly detect and identify one-dimensional and two-dimensional barcodes in any direction; it can also set to scan only specific barcode graphics and orientation; or set ROI to accelerate detection and decoding efficiency. Pharmaceutical manufacturers only need to read the one-dimensional or two-dimensional barcode on the label or sprayed on the package by using industrial camera to obtain the detailed information of drug ingredients, production date, batch number and expiration date in real time.
機器視覺檢測系統在藥瓶檢測的部分應用中確實在很大程度上提高了制藥的工作效率和準確度，對于制藥廠家而言，充分解決了人工檢測不能完成的部分，在機器視覺系統的幫助下，藥瓶檢測效率及檢測準確性都較以往大幅提升。
The machine vision detection system in some applications of drug bottle detection really greatly improves the efficiency and accuracy of pharmaceutical. For pharmaceutical manufacturers, it fully solves the part that cannot be completed by manual detection. With the help of machine vision system, the efficiency and accuracy of drug bottle detection are greatly improved.
