      轴承保持架检测案例


      一、需求背景:Requirements:

      1.轴承尼龙保持架,简称,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

      检测工位一:采用高亮红外光检测黑点   Test station 1Detecting impurityblack

      检测工位二:检测缺角                 Test station 2Detection of missing AngleLack of material

      检测工位三:检测内外毛边             Test station 3Detection 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
