A vision-based online positioning system

Abstract

The invention discloses an online positioning system based on vision. The system comprises a visual positioning system, a servo center controller and a servo motor; the visual positioning system shoots images of positioning objects on a production line, searches characteristic positions of the positioning objects according to visual characteristics, and sends results to the servo controller through a real-time industrial control bus according to a preset protocol in a preset time window; the servo controller controls the servo motor to rotate by a certain angle according to the characteristic position results; and the servo motor drives the positioning objects on the production line to rotate to finish the positioning alignment function of the positioning objects. The system replaces a traditional mechanical positioning scheme, can shoot images of containers at high speed online, searches the characteristic positions of the containers according to the visual characteristics, transmits the results by the bus and controls the actuation mechanism to act. Finally, all the containers are kept in the same position in the machine, so that subsequent production packing procedures are carried out in preset positions.

Description

technical field [0001] The invention relates to an automatic production line, in particular to a vision-based online positioning system. Background technique [0002] Modern beer and beverage production is developing in two directions, one is the high-speed production line, and the other is the personalization of the production line. The production line not only needs to have higher production efficiency, but also requires the production line to have higher production flexibility, so as to shorten the cycle of product launch and reduce the cost of market input. Especially for high-end beer and beverage lines, manufacturers often launch beautifully designed and unique containers to cooperate with marketing promotion and brand display to meet the individual needs of end customers. For example, embossing, brand marks, windows and other features appear on more and more beer, wine, liquor and beverage containers on the market. In order to improve the aesthetics of the product, ...

Problems solved by technology

This method has two disadvantages. The first one is that it can only be applied on low-speed production lines.

The second disadvantage is that the versatility is not good. For different products, corresponding mechanical devices need to be designed. For end customers, product accessories need to be purchased separately, and the cost of upgrading and maintenance is relatively high.
