The document describes functional testing of cordless wet shavers using a Laser High-Speed Micrometer. The micrometer measures vibration amplitude and frequency of assembled shavers on the production line. It uses a non-contact ThruBeam measurement technique that is not affected by the material or alignment of the shaver, providing accurate measurements within a 400 μm range at 150 Hz. The optoCONTROL 2500-35 system was selected for its independence from the target material and easy positioning without measurement errors from misalignment.

- 1. A140_e Laser High-Speed Micrometer optoCONTROL Functional testing of cordless wet shavers Cordless wet shavers represent a new generation of Ambient conditions men's shavers and therefore form the technological - Temperature: up to 30°C bridge between conventional wet shaving and - Medium: Air electrical dry shaving. In the manufacturing process of this new type of Measurement system requirements shaver completely new criteria are now being - Measurement range 400 µm followed in the quality assurance which were not - Accuracy ±20 µm relevant with conventional shavers. - Resolution ± 10 µm At the end of the production line the assembled - Frequency 150 Hz shaving appliances are passed to an inspection station and brought switched on into a V-holder Reasons for the system selection which is positioned in the beam path. The Laser - Measurement independent of material in Micrometer optoCONTROL measures the shavers comparison with other measurement techniques. for vibration amplitude and vibration frequency. The - Easy positioning. frequency is measured via the voltage output and a - No measurement errors with a misaligned target following frequency counter. object. Due to the ThruBeam measurement technique, exact alignment and orientation of the test object is not System structure optoCONTROL necessary. A further advantage is the independence optoCONTROL 2500-35 of the measurement technique from the material: The Operation mode: position/edge shavers are produced in various case materials from V-holder for shavers transparent to matt black. Since the measurement technique applied is based on optical shadow effects, no material effects on the measurement result are recorded. Laser CCD MICRO-EPSILON A member of micro-epsilon group.
