Abstract
The present disclosure provides a fully automated filling line for tissue culture flasks and a control method therefor. The line covers stations for material loading, flask loading, flask sorting, flask righting, degreasing, cleaning, filling, cap screwing, material unloading, transferring, sterilization, etc. Through the collaborative operation of a mechanical arm and a conveying line, an automatic processing flow of tissue culture flasks is achieved. The flask righting station accurately detects and processes a fallen flask through an image recognition algorithm. A visual detection mechanism includes steps of image collection, preprocessing, and feature extraction and matching, where camera parameters are optimized according to a conveying speed and a light intensity, image quality is improved through a composite filtering and correction algorithm, and a plurality of feature group vectors are extracted and input into a model to recognize a flask posture.
