                                                                                                                                                                隨著機器視覺系統在制造業的普及,外觀檢測系統對大家來說并不陌生。外觀缺陷檢測系統主要用于快速識別樣品的外觀缺陷,如凹坑、裂紋、翹曲、裂紋、污漬、沙粒、毛刺、氣泡、顏色不均勻等。檢測的樣品可以是透明體,也可以是透明體。接下來,陜西永輝將為大家展示什么是外觀缺陷檢測。

                                                                                                                                                                陜西永輝帶你了解什么是外觀缺陷檢測

                                                                                                                                                                以往產品的外觀檢查一般都是肉眼識別,有可能由于人為因素導致測量標準不統一,長期檢查會因視覺疲勞導致誤判。計算機技術與光、機、電技術的深度合作,使其具有檢測快速、準確的特點。

                                                                                                                                                              機器視覺外觀檢測

                                                                                                                                                                     如果產品的局部物理或化學性質與其他區域有較大差異,會對產品的外觀和功能產生較大影響,如金屬表面的劃痕、斑點和孔洞、紙張表面的色差和壓痕、玻璃等非金屬表面的夾雜物、損傷和污漬等。表面缺陷不僅影響產品的美觀和舒適性,還會對其性能產生不利影響。因此,制造商非常重視產品表面缺陷的檢測,以便及時發現,有效控制產品質量。他們還可以根據檢測結果分析生產過程中存在的一些問題,從而消除或減少缺陷產品的發生,防止潛在的貿易糾正,維護企業的榮譽。

                                                                                                                                                                光學檢測技術通過光源系統、圖像采集系統、圖像處理系統、機械動作系統、數據統計管理系統等對被檢產品進行照射。并揭示產品表面缺陷的特征,以便相機拍照。目前常用的光源有鹵素燈、熒光燈和發光二極管(LEDs)。LED光源以其體積小、功耗低、響應速度快、單色性好、可靠性高、光線均勻穩定、易于集成等優點得到了廣泛應用。
