Title:
光学部品を欠陥がないか検査するための検査モジュール
Document Type and Number:
Japanese Patent JP4414595
Kind Code:
B2
Abstract:
In an inspection module for inspecting optical parts (12) for defects, especially contact lenses manufactured as injection-moulded parts, the optical parts (12) are illuminated from one side and are observed from the opposite side by means of an image-resolving sensor (34). The image data of the sensor (34) are forwarded to image-processing means for identification of defects. To obtain a high throughput with a simple construction, a chain (52) of liquid-filled vessels (10) circulating in an endless line is provided. The endless line is passed in an inspection station (72) between an illumination device (32) and the image-resolving sensor (34). Handling means in the form of grippers (56, 58) revolve with the vessels (10), by means of which optical parts (12) to be inspected can be introduced into the vessels (10) at a position of the line upstream of the inspection station (72) and the inspected parts can be taken out of the vessels (10) at another position of the line.
