Abstract

The invention discloses a plastic part surface flatness detection device based on optical diffractions; the detection device comprises a detection box and a fold curtain; a detection cavity is arranged in the detection box; a sodium lamp is arranged on one side in the detection cavity; a receiving screen is arranged on the other side in the detection cavity; one side, far away from the sodium lamp, of the receiving screen is provided with an observation mirror; one side, close to the receiving screen, of the sodium lamp is provided with an adjustable crack plate. The advantages are that the detection device employs a Fraunhofer diffraction principle; the light passes the adjustable crack plate so as to form visual light intensity, and passes the first lens so as to form parallel light beams; the parallel light beams pass the crack between a block plate and the plastic part, and pass the second lens so as to irradiate on the receiving screen; the observation mirror can observe the diffraction angle changes so as to determine whether the surface is smooth and flat or not; the plastic part surface flatness detection device is simple in structure, easy to operate, high in detection precision, and safe and portable in usage.

Description

technical field [0001] The invention belongs to the technical field of optical detection, and in particular relates to a surface flatness detection device for plastic parts based on optical diffraction. Background technique [0002] In the process of light propagation, when encountering an obstacle or a small hole, the light will deviate from the path of straight-line propagation and propagate behind the obstacle, which is called light diffraction. The phenomenon that light waves will more or less deviate from the law of straight-line propagation in geometric optics after encountering obstacles. Geometric optics shows that light propagates in a homogeneous medium according to the law of straight lines, and light propagates in the interface between two media according to the law of reflection and the law of refraction. However, light is a kind of electromagnetic wave. When a beam of light passes through a barrier with holes, its intensity can spread to the geometric shadow a...
