Lens array positioning detection device

Abstract

The invention provides a Lens Array positioning detection device. A light emergent channel is installed on a support, a light source packaging part is arranged at the light incident end of the light emergent channel, the Lens Array is installed in the light emergent channel through a Lens Array mounting hole, the irradiation light source provided by the light source packaging part irradiates to the Lens Array and is then emitted through the light emergent channel, and the light emergent end of the light emergent channel is provided with an integrating sphere alignment block connected to an integrating sphere measuring instrument. The Lens Array positioning detection device not only can facilitate installation of the Lens Array in the detection process, but also can accurately measure the product quality with the integrating sphere measuring instrument, improves the production efficiency, and ensures the product quality.

Description

Technical field [0001] The invention relates to the technical field of stage equipment, and more specifically to a lens array positioning detection device. Background technique [0002] The lens array (lens array) has the effect of improving the uniformity of light and collimating the light, and is widely used in stage lights, projectors and other equipment. In order to ensure the light-emitting effect, quality inspection of the incoming materials of the lens array is required. [0003] The existing detection methods use a combination of visual inspection and vernier caliper measurement. Employees observe the surface of the lens array material to judge whether there are any appearance defects such as scratches, plane bending and deformation, and uneven spherical surface distribution. In addition, in order to ensure the size requirements of the lens array material, the length, width, and thickness of the lens array material are measured by a vernier caliper. [0004] However, there...

Problems solved by technology

[0004] However, there are many shortcomings and deficiencies in the above-mentioned detection method. For example, when detecting the size of the lens array material, due to the large number of measurement parameters and inconvenient work for employees, the detection takes a long time, and the measurement accuracy of the vernier caliper is low, which affects the lens array. Measurement results of dimensional parameters

The existing appearance inspection method is that employees visually inspect the appearance defects of the lens array (such as scratches, plane bending deformation, uneven distribution of spherical surfaces, etc.), so it is impossible to accurately measure and judge the light uniformity and coating of stage lighting materials. It is difficult to guarantee the quality of products such as stage lights and projectors due to parameters such as band and spherical surface angle.
