Multishaft directional fault tolerant 2D self-compensating system

Abstract

A fault-tolerant multi-axial 2D automatic compensation system for the carrier of ink box used for ink-jet printer or plotter is composed of a carrier unit with gap sensor and skew sensor, a reciprocating unit, and a driver with a rotary unit pivoted with said carrier unit and a lifting unit pivoted with said reciprocating unit and doing slide shift to make the rotation surface of said rotary unit and the lifting straight line of said lifting unit to form a space coordinate system composed of X-Y plane and Z axis. It can regulate the gap between the paper and nozzle to be optimal and automatically compensate the errors of parts, machining and assembling.

Description

technical field [0001] The present invention relates to a multi-axis fault-tolerant two-dimensional automatic compensation system, in particular to a kind of machinery and equipment applied to biaxial or multi-axial movement, such as inkjet printers, inkjet multifunction machines, or inkjet graphics The automatic compensation system for nozzle gap adjustment and automatic positioning of the machine. Background technique [0002] Apply the principle of axial movement to adjust the working position of the parts to realize the field of material handling equipment or equipment, such as the printer of the main data output tool in the computer interface equipment, among which the inkjet printer has rich color changes and reasonable The price makes it the most common and popular computer standard equipment nowadays. As far as the technology research and development of inkjet printers is concerned, the most important thing is the quality of the printed ink. How to print good qualit...

Problems solved by technology

[0004] In the ink cartridge carrier of the above-mentioned existing inkjet printer, the gap between the nozzle and the paper is adjusted mechanically by an adjustment rod arranged on the printer casing, and the shaft rod of the ink cartridge carrier is mechanically adjusted. Limited to the volume configuration of the casing and related parts, the adjustment lever can only provide a small number of fixed gap positions for adjustment, which is difficult to meet various paper thicknesses. When the gap is too large, inkjet printing will cause diffusion and blurring In some cases, when the gap is too small, it will cause ink dragging, which not only reduces the printing quality, but also leaves stains on the paper, which is a major weakness of inkjet printers.

[0005] Furthermore, there are mold tolerances in the manufacture of each part of an inkjet printer, so that there are considerable errors in the parts after they leave the factory, and various errors are also collected after assembly, such as the shaft of the ink cartridge carrier Not parallel to the shaft of the paper feed roller, the eccentricity of the left and right shaft holes makes the shaft skew, the eccentric error of the shaft hole and its bushing makes the shaft skew, the size error between the ink cartridge and the ink cartridge carrier, the nozzle and The angle error of the ink cartridge, etc., all constitute the discontinuous phenomenon of skew and discontinuity of the inkjet line when printing, which greatly reduces the printing quality of the inkjet printer

[0006] From the above, it can be seen that the ink cartridge carrier and its printing process of the above-mentioned existing inkjet printers obviously have inconvenience and defects in actual use, and need to be improved.
