A pearl automatic drop and image acquisition device for sorting pearl shapes

Abstract

The invention discloses an automatic pearl falling and image acquiring device for sorting pearl shapes, wherein a light ball is mounted on a light ball bracket, three camera apertures are formed in the light ball, and are arranged at intervals of 120 degrees and on a 75-degree ring on the upper half circle of the light ball, the upper end and the lower end of the light ball are connected with a pearl falling conduit, the pearl falling conduit at the upper end of the light ball is connected with a pearl sequencing and feeding device, an arc-shaped guide block is arranged between the high side and the low side of the radial section of the inner wall of a feeding barrel, a guide slot is formed between the guide block and the inner wall of the feeding barrel, an inlet is formed in the high side of the guide slot, and the low side of the guide slot is communicated with the discharge opening of the feeding barrel. The automatic pearl falling and image acquiring device can control the quantity of pearls in the feeding barrel, so that the guide block has little possibility of blocking. In addition, the light ball of the automatic pearl falling and image acquiring device is designed with the three camera apertures, every two of the three camera apertures are perpendicular to each other, and when three cameras shoot, the shape information of the pearls can be effectively provided, and thus the shape sorting accuracy is improved.

Description

technical field [0001] The invention relates to an automatic drop and image collection device for sorting pearl-shaped pearls. Background technique [0002] The pearl automatic drop and image acquisition device for sorting pearl shapes includes two parts: the pearl automatic drop device and the image acquisition device. The Chinese invention patent with the publication number of CN101348194 disclosed a method for controlling the sorting and falling of pearls on January 29, 2009. Feeding device. Among them, the material barrel is set at an incline, and the material barrel is provided with a material inlet and a material outlet. The bottom is affixed to the lower end cap, the center of the bottom of the turntable is affixed to a rotating shaft positioned on the lower end cap, and each bead hole is equipped with a feeding mechanism that moves up and down. [0003] But when more than half of the pearls in the feed barrel, the discharge hole is very easy to enter more than two ...

AI Technical Summary

Problems solved by technology

[0003] However, when more than half of the pearls in the barrel are used, more than two pearls can easily enter the discharge hole and block the guide block at the same time.

And when there are two or more pearls in the blanking hole, when the blanking hole is displaced to the entrance of the guide block, it is easy to cause jamming

[0004] In addition, in the traditional photosphere in the image acquisition device, the camera hole is opened at an angle of 45 degrees from the center of the hemisphere to form a 90-degree viewing angle, but the captured image information is insufficient, which affects the shape judgment
