Method and system for controlling axis operation of multi-axis equipment

Abstract

The invention provides a method and system for controlling shafts of a multi-shaft device to operate. The method comprises the steps that firstly, the information of the position relation between a component driven by a first actual shaft and the component driven by a second actual shaft in the normal work process of the multi-shaft device is acquired, and the operating information of a first virtual shaft is constructed based on the operating information of the first actual shaft in the normal work process of the multi-shaft device; then, the operating information of a second virtual shaft is constructed based on the operating information of the first virtual shaft and the acquired position relation information; then, the first constructed virtual shaft and the second constructed virtual shaft are started to operate, the current operating information of the second virtual shaft is output to an electronic cam, the second actual shaft is controlled by the electronic cam, the second actual shaft is made to operate synchronously relative to the first actual shaft, therefore, the shafts of the multi-shaft device are controlled, especially a silk-screen printing device is controlled, and the silk-screen printing device can achieve planar, circular, elliptical and polygonal screen printing.

Description

technical field [0001] The invention relates to the field of axis control of equipment, in particular to a method and system for controlling axis operation of multi-axis equipment. Background technique [0002] Screen printing belongs to stencil printing, and is called the four major printing methods together with offset printing, embossing printing, and gravure printing. When printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh with the graphic part, forming the same graphic as the original. Screen printing equipment is simple, easy to operate, easy to print and plate-making, with low cost and strong adaptability. Screen printing has a wide range of applications, and common printed materials include: color oil paintings, posters, business cards, bound covers, commodity signs, and printed and dyed textiles. [0003] Screen printing is generally divided into flat screen printing and curved screen printing according to the ...

AI Technical Summary

Problems solved by technology

[0005] However, the existing curved surface screen printing is generally printed on a standard circular workpiece, and the silk screen printing on the entire circumference of an oval or other shaped workpiece is useless. The reason is that the radius of the workpiece will change during the rotation process, and the gap between the workpiece and the screen The silk screen point of the contact is also changing, such as Figure 1c As shown, when the elliptical workpiece 2" rotates clockwise, since the screen 11 can only move horizontally, the screen 11 will be separated from the elliptical workpiece 2", and printing cannot be continued

[0006] In view of the fact that the existing curved screen printing can only be applied to circular workpieces, it is extremely necessary to improve the existing curved screen printing
