An automatic carpet cutting device and method using real-time machine vision technology

Abstract

The invention relates to a carpet automatic cutting device and a carpet automatic cutting method using real-time machine vision technology. The machine vision technology, and modern motor and control technology are adopted, and therefore in the process of carpet production, manual demands are reduced and labor intensity of workers is lowered. The carpet automatic cutting device comprises a cutting platform. The cutting platform is connected with a carpet feeding device, at least one imaging device for obtaining polyvinyl chloride (PVC) carpet images which enter a cutting region in real time is arranged above the connecting position between the cutting platform and the carpet feeding device, the imaging device enables the obtained images to be sent to a processor module, the processor module identifies edges of a carpet body in the images and then determines a cutting boundary, and a motion control module is used for controlling a cutting system installed on the cutting platform, and according to the determined cutting boundary, completing cutting of a PVC carpet.

Description

Technical field [0001] The invention relates to a PVC carpet cutting device, in particular to a carpet automatic cutting device and method using real-time machine vision technology. Background technique [0002] Carpet is a very commonly used item, which has been widely used in many places such as homes, service places, factories, offices and so on. Among them, PVC carpet is the most widely used carpet. The so-called PVC carpet is to paste the carpet body on the PVC substrate sheet by hot melt. The advantages of this kind of PVC carpet are stable structure and convenient use. [0003] Traditional PVC carpet production and processing methods are divided into three steps. The first step is to cut the carpet body into a preset size; the second step is to put the carpet body on a large piece of hot-melt PVC substrate sheet; the third step, according to the size of the carpet body, the large piece of PVC carpet PVC carpet cut into small pieces. Currently the third step is done manua...

Problems solved by technology

[0006] Although the above two patents can realize the non-manual cutting of PVC carpet, they do not solve the problem of how to identify the edge of the carpet accurately and in real time, that is, to identify the edge of the carpet when feeding, and determine the movement route of the cutter. Therefore, in the cutting process, the cutting error of the edge of the carpet is prone to be too large, and the cutting accuracy cannot be guaranteed, and the sitting efficiency is also very low.
