AI Technical Summary
Technical Problem
Existing methods for inspecting the appearance of injection molded parts mainly rely on visual inspection, which leads to inconsistent written descriptions from different inspectors and low efficiency in tracing the causes of defects.
Method used
The product 3D design drawing is set and sliced using the xyz three-axis coordinate system. The parallel red line of the inspection station and multiple intersecting planes are used for marking. Different types of defects are marked with color to form an intuitive outer contour drawing.
Benefits of technology
It improves the efficiency and accuracy of appearance inspection of injection molded parts, simplifies the process of tracing the cause of defects, and reduces time consumption.

Abstract
本发明提供的注塑件外观检测方法，包括以下步骤：S1.设定xyz三轴坐标系，将产品3D设计图放入该坐标系并进行切片，获得带有多根标记线的外轮廓图档；S2.将待测产品放置在该检测台上；S3.观察待测产品，若其上存在缺陷，则在外轮廓图档对应标记线的交点或形成的网格处进行标记；S4.取出待测产品；S5.重复步骤S1至S4，完成所有待测产品的外观检测，获得标记后的外轮廓图档；该方法操作简单、易于实施，后续分析原因时，只需观察外轮廓图档中标记最多处即可，对缺陷的感受更为直观、准确，耗时少，追溯缺陷原因的效率高。
