一、需求背景:Requirements:
1.軸承尼龍保持架,簡(jiǎn)稱(chēng)尼保,材質(zhì)是聚酰胺,聚酰胺尼龍材料彈性大和重量輕的優(yōu)勢,這種保持架有非常好的滑動(dòng)和自潤滑性能。制造過(guò)程采用注射成型法,由于材料及制造工藝,容易出現以下不良:混有雜質(zhì)、毛邊、缺角等。這類(lèi)不良影響軸承的可靠性、靜音、裝配,需要投入專(zhuān)業(yè)檢測人員細心挑選后方可使用。
2.軸承尼龍保持器品類(lèi)規格較多,軸承類(lèi)產(chǎn)品應用廣,人力投入大
二、項目可行性評估the project feasibility assessment
針對尼龍保持器各類(lèi)不良,收集了各類(lèi)不良進(jìn)行評估Nylon retainer for all kinds of bad, is a collection of all kinds of bad for evaluation
不良類(lèi)別Undesirable category | 解決方式The solution |
混有雜質(zhì)(黑點(diǎn))Mixed with impurities (black) | 采用高亮高穿透光譜段成像Using highlighting height through spectral imaging |
毛邊burrs | 內外弧表面檢測Within the outer arc surface detection |
缺角(主要缺陷) missing Angle (Main defect) | 相似度匹配檢測,輪廓檢測Similarity matching detection, contour detection |
兼容性Range of application:規格接近(直徑相差共景深、材質(zhì)相同)可共用,切換其他料號需更換振動(dòng)盤(pán),由于產(chǎn)品厚度及角度影響,需調節光源位置及亮度,林洋公司提供培訓及技術(shù)支持
產(chǎn)品規格:直徑5-30mm
三、解決方案 the solution
Products through the vibration plate into the glass plate→Starting test→Good parts into the OK,Bad product into the NG
檢測工位一:采用高亮紅外光檢測黑點(diǎn) Test station 1:Detecting impurity(black)
檢測工位二:檢測缺角 Test station 2:Detection of missing Angle(Lack of material)
檢測工位三:檢測內外毛邊 Test station 3:Detection of diameter burrs
檢測效率:產(chǎn)品尺寸越小,檢測速度越高,φ5mm產(chǎn)品檢測速度約300/min,φ30產(chǎn)品檢測速度約80/min Detection efficiency: the product size is smaller, the higher the detection speed, phi product testing speed is about 300 / min 5 mm, phi 30 product testing speed is about 80 / min
