一、需求背景:Requirements:
1.轴承尼龙保持架,简称尼保,材质是聚酰胺,聚酰胺尼龙材料弹性大和重量轻的优势,这种保持架有非常好的滑动和自润滑性能。制造过程采用注射成型法,由于材料及制造工艺,容易出现以下不良:混有杂质、毛边、缺角等。这类不良影响轴承的可靠性、静音、装配,需要投入专业检测人员细心挑选后方可使用。
2.轴承尼龙保持器品类规格较多,轴承类产品应用广,人力投入大
二、项目可行性评估the project feasibility assessment
针对尼龙保持器各类不良,收集了各类不良进行评估Nylon retainer for all kinds of bad, is a collection of all kinds of bad for evaluation
不良类别Undesirable category | 解决方式The solution |
混有杂质(黑点)Mixed with impurities (black) | 采用高亮高穿透光谱段成像Using highlighting height through spectral imaging |
毛边burrs | 内外弧表面检测Within the outer arc surface detection |
缺角(主要缺陷) missing Angle (Main defect) | 相似度匹配检测,轮廓检测Similarity matching detection, contour detection |
兼容性Range of application:规格接近(直径相差共景深、材质相同)可共用,切换其他料号需更换振动盘,由于产品厚度及角度影响,需调节光源位置及亮度,林洋公司提供培训及技术支持
产品规格:直径5-30mm
三、解决方案 the solution
Products through the vibration plate into the glass plate→Starting test→Good parts into the OK,Bad product into the NG
检测工位一:采用高亮红外光检测黑点 Test station 1:Detecting impurity(black)
检测工位二:检测缺角 Test station 2:Detection of missing Angle(Lack of material)
检测工位三:检测内外毛边 Test station 3:Detection of diameter burrs
检测效率:产品尺寸越小,检测速度越高,φ5mm产品检测速度约300/min,φ30产品检测速度约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
