Machine vision based ultrasonic object cutting device and cutting method thereof

Abstract

The invention provides a machine vision based ultrasonic object cutting device. The device comprises a conveying mechanism for sequentially conveying objects to an image acquiring area and a cutting area, a machine vision mechanism for acquiring a starting position for of tracking positioning information, an object cutting mechanism for adjusting the cutting parameters and selecting the cutting mode based on the tracking positioning information and then performing tracking type or fixed point type positioning and cutting on the objects conveying in the cutting area by ultrasonic cutting, and acontroller, wherein the machine vision mechanism is arranged above the image acquiring area in a conveyor belt; and the object cutting mechanism is arranged above the cutting area in the conveyor belt. The device has the characteristics of being fast to cut, prevented from adhering to a cutter after cutting, and hard to deform during object cutting; the object cutting efficiency, precision and accuracy can be improved. The invention also provides a high cutting speed and high cutting precision type machine vision based ultrasonic object cutting method. With the adoption of the method, the object cutting efficiency and accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of article cutting, and more specifically, relates to a machine vision-based ultrasonic article cutting device and a cutting method thereof. Background technique [0002] Article cutting machinery is an emerging industry. With the improvement of people's living standards, the requirements for articles are increasing year by year, and the requirements for the quality and hygiene of articles are becoming stronger and stronger. [0003] Most of the traditional article cutting production lines cut articles, unfired mud bricks, soap, small tablets and other articles. Now they all use mechanical cutting such as hob mechanism to cut the articles through extrusion deformation and shear force. However, this traditional way of cutting items not only has the disadvantages of serious deformation of the item, more debris, and rough cutting surface during the cutting process, but also requires regular cleaning of the knif...

AI Technical Summary

Problems solved by technology

However, this traditional way of cutting items not only has the disadvantages of serious deformation of the item, more debris, and rough cutting surface during the cutting process, but also requires regular cleaning of the knife due to the sticking phenomenon of the item, especially when processing items like cream pastry and chocolate. For materials that are easy to stick to knives such as sandwiches and sandwiches, the traditional method of cutting items greatly reduces production efficiency

[0004] In addition, the traditional article cutting production line cannot accurately locate the article, resulting in low cutting accuracy and cutting precision, which not only increases the cutting failure rate and causes article waste, but also greatly reduces the quality of article cutting and affects the subsequent packaging of articles. Production of products and other processes

In addition, the existing article cutting method also has low production efficiency, which makes it unsuitable for large-scale production
