A detection device for a light guide strip of an automobile lamp

Abstract

The invention discloses an automobile lamp light guide bar detecting device. The automobile lamp light guide bar detecting device comprises a base, a first reference piece, a first light source, a first positioning piece, a second reference piece, a second light source and a second positioning piece, wherein the first reference piece is used as a reference for detecting a left light guide bar on the outside and has specified light transmittance, curvature and length; the first light source is fixed on the base and is provided with two first light emitting ends which are respectively used for enabling the first reference piece and the left light guide bar on the outside to emit light; the intensity of light which is respectively emitted from the two first light emitting ends is consistent; the first positioning piece is fixed on the base; the second reference piece is used as a reference for detecting a right light guide bar on the outside and has specific light transmittance, curvature and length; the second light source is fixed on the base, and is provided with two second light emitting ends which are respectively used for enabling the second reference piece and the right light guide bar on the outside to emit light; the intensity of the light which respectively emitted from the two second light emitting ends is consistent; and the second positioning piece is fixed on the base. By the automobile lamp light guide bar detecting device, the light transmitting effect of the automobile lamp light guide bars can be simply and accurately determined.

Description

technical field [0001] The invention relates to a testing device, in particular to a testing device for a light guide strip of an automobile lamp. Background technique [0002] The light guide strips of automobile lamps generally include two symmetrically arranged light guide strips on the left and right. The light guide strips are both relatively long. The quality of the light guide strip requires strict inspection of the light transmission effect of the light guide strip of the car lamp during the production process. The standard is mainly based on the comparison and analysis of the light transmission effect of each part of the product itself. This detection method mainly has the following defects: 1. It is difficult to observe the stain on the light guide strip of the car light; 2. It is impossible to determine the quality of the light guide strip of the car light Whether the luminous intensity meets the standard; 3. It is impossible to determine the deformation of the l...

It is impossible to determine the quality of the light guide strip of the car light Whether the luminous intensity meets the standard; 3. It is impossible to determine the deformation of the light guide strip of the car light; therefore, when using this detection method to detect the light guide strip of the car light, it is not only difficult to operate, but also has large errors, which makes it difficult to guarantee product quality
