Elevation type triaxial connecting system for jet printing

Abstract

The invention relates to a transmission mechanism of a jet printing machine, in particular to a lifting type three-axis linkage mechanism for jet printing. It mainly solves the technical problems of complex mechanism, low sensitivity, small starting torque inertia and narrow speed regulation range existing in the six-axis linkage control. The technical solution of the present invention is: an elevating three-axis linkage mechanism for spray printing, including a plane mechanism distributed by three-axis linkage and a lifting mechanism for realizing the lifting of the plane mechanism. The three-axis linkage plane mechanism is installed on the lifting mechanism, and the plane mechanism has three Two degrees of freedom of rotation around the respective Z-axis, the lifting mechanism can move up and down along the Z-axis, the plane mechanism constitutes the mechanical arm, and the end of the mechanical arm is connected with the printing device to realize printing. The mechanical arm contains three degrees of freedom of rotation around their respective Z axes. The three degrees of freedom of rotation around their respective Z axes enable the mechanical arm to perform relative linkage through three rotations around their respective Z axes in a fixed plane, realizing steel The arc trajectory required for roll printing; the above four degrees of freedom, according to the instructions from the microcomputer, coordinate with each other and run according to the required trajectory and speed. The invention is mainly used in jet printers.

Description

Technical field: [0001] The invention relates to a transmission mechanism of a jet printing machine, in particular to a lifting type three-axis linkage mechanism for jet printing. Background technique: [0002] The spray printing equipment is a fully automatic marking system controlled by a computer, which directly forms marks on the side surface and top surface of the steel coil by spraying dot matrix. At present, the hot-rolling production lines of domestic and foreign iron and steel enterprises generally use dot-matrix inkjet printing for hot-steel coil labeling. Dot-shaped paint is sprayed on the position to form characters with dots. Because the jet printer also includes a sensor and has a relatively large mass, the side spray on the side surface of the steel coil and the top spray on the top surface of the steel coil are mostly separately controlled by the jet printer. [0003] At present, a articulated robot with 6-axis linkage is used, which performs top spraying a...
