Plane-engraved asymmetric 5DOF (Degree of Freedom) series-parallel robot based on machine vision

Abstract

The invention relates to a plane-engraved asymmetric 5DOF (Degree of Freedom) series-parallel robot based on machine vision, which comprises an image acquisition system, an art engraving technique processing system, a control system and an asymmetric structure 5DOF series-parallel engraving mechanism, wherein the image acquisition system comprises a CCD (Charge Coupled Device) camera and an imageacquisition card which are connected mutually; the art engraving technique processing system comprises a PC (Personal Computer) provided with art engraving processing software; the control system comprises a robot movement control card and an electric cabinet; the CCD camera and the electric cabinet are connected with the PC; and the asymmetric structure 5DOF series-parallel engraving mechanism is connected with the electric cabinet. By adopting a computer image processing technique and a robot intelligent control technique, the plane-engraved asymmetric 5DOF series-parallel robot can realizeengraving machining by selecting different materials and artistic styles according to images of figures or sceneries and has the advantages of high operation speed, fine engraving, and the like.

Description

technical field [0001] The invention relates to the fields of machine vision technology and electromechanical control technology, in particular to a plane engraving asymmetrical 5DOF hybrid robot based on machine vision. Background technique [0002] Ordinary flat sculptures of portraits or landscapes are handmade by artists. The artistic style and carving quality of the work mainly depend on the skill level of the maker. The labor productivity is low, the cost is high, and some special production techniques, difficult to inherit. With the continuous expansion of market demand and the development of modern technology, more and more artworks are produced with the help of modern equipment. However, these devices often require operators to input relevant information such as AUTOCAD images, artwork model data, and CNC machine tool motion programs, which consumes considerable time and technical manpower, and is also difficult to operate. It is mainly suitable for large-scale pro...

Problems solved by technology

However, these devices often require operators to input relevant information such as AUTOCAD images, artwork model data, and CNC machine tool motion programs, which consumes considerable time and technical manpower, and is also difficult to operate. It is mainly suitable for large-scale production. Processing, cannot replace manual carving artists to realize personalized carving works customization

[0003] After searching the existing technology, it is found that the patent CN1409659A proposes a portrait caricature drawing robot, which converts the image trajectory into the robot's motion instructions through the vectorization algorithm and caricature processing algorithm, which has a certain artistry, but its painting style is only caricature style. Moreover, the operating speed and control accuracy of the robot with a series structure are far inferior to those of a robot with a parallel mechanism under heavy loads. It can only be used for drawing on a plane, and cannot be used for engraving on other materials.
