This article mainly introduces the application of machine vision technology<\/a> in automatic inspection<\/a> of plastic product surface defects such as liquid level, seal and cap of the bottle. The final result of the test is shown in the figure below.<\/p>\n

In the molding process of plastic products, due to the influence of materials, molding process, mold, product design and equipment, various surface defects often occur. For example, the injection products may have insufficient filling, depression, sink marks, dark lines, and fusion. Traces, silver, spots, oil, burrs, bubbles, delamination, turbulence, spray marks, dull and uneven gloss, warpage, surface scratches and cracks.<\/p>\n

There are two types of methods for plastic product surface defects inspection<\/a>, conventional detection methods and automatic detection methods. Traditional detection methods include manual visual inspection<\/a> and surface stroboscopic detection. The method is inefficient and error-prone, but most companies still use such methods. In recent years, the detection of defects in plastic products has adopted automatic inspection methods<\/a> based on machine vision technology, and has been gradually promoted and applied in enterprises.<\/p>\n
