Plastic is ubiquitous in daily life and is widely used in industrial products, where it is often fashioned into components like drive gears, bearings, and bushings. Therefore, during the production of industrial goods, plastic parts need to be inspected to ensure product quality.
To meet production requirements, plastic part inspection generally follows two directions: dimensional inspection and defect identification. Traditional inspection methods rely on manual inspection, where workers visually compare and observe, removing defective items. Alternatively, calipers are used for dimensional measurements. However, manual inspection lacks accuracy, leading to errors, while caliper-based measurement is inefficient and not suitable for irregularly shaped workpieces.
The use of machine vision systems equipped with high-resolution telecentric lenses can replace manual inspection, allowing for batch inspection of plastic parts for dimensions and defects, thereby improving inspection efficiency. This reduces the long-term investment in labor and management costs, ultimately lowering the production company's costs.
Telecentric lenses offer characteristics like high depth of field and low distortion, making them ideal for machine vision systems. They can be used to inspect objects that are not on the same plane, objects with thickness, and objects requiring low distortion, consistent brightness, and defect detection through parallel illumination from a single direction. Telecentric lenses ensure that machine vision inspection achieves optimal results, making them a crucial component in machine vision systems.
