Electric toothbrush head dynamic feeding system based on vision

Abstract

The invention relates to an electric toothbrush head dynamic feeding system based on vision. The system comprises a conveying device, a visual detection device and a control module, system calibration, brush head recognition and positioning, grabbing sequence optimization and robot trajectory planning are conducted, toothbrush heads are conveyed to a robot working space from a hopper through the conveying device, images are collected through the visual detection device, and a support vector machine and an ellipse fitting method are adopted to identify the toothbrush heads and calculate the poses, and meanwhile, the poses are updated in real time. After the toothbrush head pose information is obtained, an improved tabu search algorithm is adopted to plan a grabbing sequence, a robot carries out trajectory planning after receiving an instruction, and the toothbrush heads are conveyed to a target position from a grabbing position. The electric toothbrush head dynamic feeding system can adapt to feeding of various toothbrush heads, has higher automation and flexibility compared with a feeding mode in the prior art, can shorten the movement distance of the robot while completing feeding, and can be used for feeding in the processes of bristle planting, packaging and the like of the toothbrush heads.

Description

technical field [0001] The invention relates to the field of electric toothbrush manufacturing, in particular to a vision-based dynamic feeding system and method for brush heads of electric toothbrushes. Background technique [0002] In recent years, with the continuous improvement of my country's industrial automation level, the application of machine vision in material sorting has become more and more mature. Traditional toothbrush feeding mainly relies on labor, which is costly and inefficient. The normal production cycle is often affected due to improper placement of toothbrushes. However, the existing toothbrush automatic feeding equipment occupies a large area, has a complex structure and poor flexibility, and cannot meet the feeding requirements of different toothbrushes. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the present invention provides a vision-based dynamic feeding system for the head of an electric toothbr...
