Problems solved by technology
[0003] At present, the flat knitting machines for the wool weaving industry on the market mainly rely on the manual method after weaving to detect whether stitches are missing. Using the traditional industry mode, the efficiency is low and the cost is high. The quality of weaving cannot be fed back to the numerical control system to form a closed-loop optimization. control

The invention discloses a control system and method for knitting missed stitches of a flat knitting machine on the basis of machine vision. The system comprises a flat knitting machine master control board, a flat knitting machine head controller, a motor position encoder, a camera, an assisting drive mechanism, a communication module, and a vision operating module. The flat knitting machine master control board, the flat knitting machine head controller and the motor position encoder are connected in parallel and communicated through a CAN bus. The vision operating module is connected with the assisting drive mechanism. The camera is connected with the vision operating module. The vision operating module is connected and communicated with the communication module. The communication module is connected and communicated with the flat knitting machine master control board through a CAN bus. The system runs stably and reliably. Through a real-time vision detection method, missed stitch defects during knitting of a flat knitting machine head can be detected in an automatic manner.
Description
technical field [0001] The invention belongs to the technical field of flat knitting machines in the wool weaving industry, in particular to a control system and method for detecting missing stitches in flat knitting knitting based on machine vision. Background technique [0002] With the continuous improvement of the market's precision in the processing technology of the wool weaving industry and the rapid development of the enterprise itself, the lack of human resources in the domestic market in my country, and the continuous increase in labor costs, there is an urgent need for continuous improvement in the intelligence of wool flat knitting machines, such as reducing The probability of missing stitches in knitting improves the yield rate of knitting and increases the profit of the enterprise. [0003] At present, the flat knitting machines for the wool weaving industry on the market mainly rely on the manual method after weaving to detect whether stitches are missing. Usin...
