避免口罩生產過程中出現任何瑕疵或缺損，減少出錯率，機器視覺檢測系統完成口罩缺陷檢測的最后一道程序，提高口罩產品的質量及生產速度。在此過程中，工業相機能準確且快速擷取最真實影像數據，搭配后端分析軟體，能幫助生產線人員在最短時間內做出最有效率的判斷，真正減少人工成本以及制程中口罩被污染的機率。
The machine vision inspection system can complete the last procedure of mask defect detection and improve the quality and production speed of mask products. In this process, the industrial camera can accurately and quickly capture the most real image data. Combined with the back-end analysis software, it can help the production line personnel make the most efficient judgment in the shortest time, and truly reduce the labor cost and the probability of mask contamination in the process.
口罩瑕疵檢測篩選系統的檢驗流程:
Inspection process of mask defect detection and screening system:
1.中心運動系統：由電機、主軸、玻璃盤及相關配件組成，實現中心系統平穩地轉動。
Central motion system: it is composed of motor, spindle, glass plate and related accessories to realize the stable rotation of the central system.
2.視覺檢測系統：由6個相機及相應光源組成，分別實現對物料上表面、物料下表面及物料側環面進行拍照。
Visual inspection system: it is composed of 6 cameras and corresponding light sources, which can take pictures on the upper surface, lower surface and side ring surface of materials respectively.
3.軟件分析控制系統：相機取像后，通過主機軟件分析，判定被檢測物料的屬性：合格品、不合格品、待檢品三種。
Software analysis control system: after the camera takes the image, through the host software analysis, determine the properties of the tested materials: qualified, unqualified and to be inspected.
4.出料分檢系統：軟件判定物料的屬性后，通過PLC電氣控制系統，出料分檢系統按照軟件指標的屬性，對物料進行良品、不良品、待檢品進行分類出料。
Material distribution and inspection system: after the software determines the properties of materials, through the PLC electrical control system, the system classifies and discharges the good products, defective products and products to be inspected according to the attributes of the software indicators.
5.PLC電氣控制系統：通過PLC搭配視覺檢測軟件，完成整套設備的控制動作。
PLC electrical control system: complete the control action of the whole set of equipment through PLC with visual inspection software.
口罩在生產過程中會出現耳繩脫落、排齒不對稱、污漬、破損等缺陷，這些缺陷的出現嚴重影響口罩的質量，降低口罩的性能或無法使用。人眼目測很難對產品的質量進行精確、穩定地檢測。機器視覺檢測系統主要針對以下內容對口罩進行全方位的檢測。
In the production process, there will be ear rope falling off, asymmetric teeth arrangement, stains, damage and other defects, which seriously affect the quality of the mask, reduce the performance of the mask or can not be used. It is difficult to detect the quality of products accurately and stably by human eye measurement. The machine vision inspection system mainly aims at the following contents to carry on the omni-directional inspection to the mask.
口罩切片后檢測：
After slicing, the mask was detected
1、口罩長度、寬度等檢測需求；
The length and width of the mask should be tested;
2、口罩切片大小；
The size of the mask slice;
3、折痕數量一致。
The number of creases is the same.
耳帶焊接后檢測：
Inspection after welding of ear band:
1、檢測耳帶長度;
The length of ear band was measured;
2、耳帶焊接檢測;
Ear band welding inspection;
3、包邊長度檢測。
Detection of hemming length.
口罩包裝前檢測：
Inspection before mask packaging:
1、產品種類識別；
Product type identification;
2、表面缺陷檢測；
Surface defect detection;
3、表面生產批號識別；
Identification of surface production batch number;
4、產品顏色識別。
Product color identification.
口罩包裝完成檢測：
Complete inspection of mask packaging:
1、檢測包裝是否合格；
Check whether the package is qualified;
2、口罩數量計算。
The number of masks was calculated.
視覺檢測系統與自動化生產設備的有利結合，有效幫助口罩生產企業對于產品品質把關方面的檢驗。機器視覺檢測系統提供高速、高準確性，且可長期且穩定地進行重復性工作，與人工檢測相比，大量減少出錯率，也避免人眼檢測彈性疲乏的缺點，提升產品質量及生產速度。
The combination of visual inspection system and automatic production equipment can effectively help mask manufacturers to check the quality of products. Machine vision inspection system provides high-speed, high accuracy, and long-term and stable repetitive work. Compared with manual detection, it can greatly reduce the error rate, avoid the weakness of human eye detection elasticity fatigue, and improve product quality and production speed.
