An adaptive light source adjustment mechanism and method based on fruit size

Abstract

The invention discloses a fruit size based self-adaption light source adjusting mechanism and method. The mechanism comprises a base frame part, a movable frame part and a swing arm light source part,wherein the base frame part is composed of a base frame as well as a vertical motor and a lead screw mounted on the base frame; the movable frame part is composed of a double-shaft motor, screw rodswith opposite rotary directions, a sliding block mechanism and a guide rail matched with the screw rods and the like; the swing arm light source part is composed of a light source mounting rack mounted on a swing arm as well as a light source, a lamp barrel and a radiating fan fixedly mounted on the light source mounting rack; the movable frame part is matched with a guide rod and the lead screw of the base frame through a linear bearing and a screw nut; a middle circular hole of the swing arm light source part is matched with a protruding small column of the movable frame; and an upper strip-shaped through groove is matched with movable small columns of two sliding blocks of the movable frame. The mechanism can adjust the light source illuminating angle and position according to sizes ofdifferent fruits and can improve the spectrum detection precision of the fruit quality.

Description

technical field [0001] The invention relates to an adaptive light source adjustment mechanism and method, in particular to an adaptive light source adjustment mechanism and adjustment method based on fruit size, which is mainly used for online detection, sorting and grading of fruit quality, and improves the sorting accuracy. Background technique [0002] my country is a large fruit producing country, with a wide variety of fruits and high quality fruits. With the continuous improvement of people's living standards, consumers' demand for high-quality and high-quality fruit products continues to increase; although my country is a large fruit producing country, it is not a strong production country. The post-harvest fruit commercialization technology is relatively backward, its commodity is low, and its market competitiveness is weak. The application of online detection and grading technology can realize the sorting and grading of fruits according to different indicators, and ju...

Problems solved by technology

[0002] my country is a large fruit producing country, with a wide variety of fruits and high quality fruits. With the continuous improvement of people's living standards, consumers' demand for high-quality and high-quality fruit products continues to increase; although my country is a large fruit producing country, it is not a strong production country. Post-harvest fruit commercialization technology is relatively backward, its commerciality is low, and its market competitiveness is weak. However, the application of online detection and grading technology can realize the sorting and grading of fruits according to different indicators, and judge the price according to quality

In the commercial processing of vulnerable fruit quality detection and sorting, when fruits of different sizes and shapes pass through the detection system with a fixed light source, the accuracy of fruit quality detection will be greatly affected due to the difference in size and shape, mainly due to the size of the same variety of fruit. There are differences and there are large differences between the sizes of fruits of different quality. The current online fruit quality inspection system can reduce the detection accuracy caused by the size difference of the same variety of fruit and the adaptability of the same fruit quality inspection system to different varieties of fruits needs to be further resolved.
