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 machine device applied to biaxial or multi-axial movement, such as an inkjet printer, an inkjet multifunction machine, or an inkjet drawing 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 machine parts to realize the field of material handling machines 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 quality ef...

Problems solved by technology

[0004] In the above-mentioned ink cartridge carrier of the existing inkjet printer, the gap between the nozzle and the paper is mechanically adjusted by an adjustment lever arranged on the printer casing to adjust the shaft rod of the ink cartridge carrier. 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, when the various parts of the inkjet printer are manufactured, there will be mold tolerances, so that the parts will have considerable error values ​​after they leave the factory, and various errors will also be collected after assembly, such as the shaft of the ink cartridge carrier. It is not parallel to the shaft of the paper feed roller, the eccentricity of the shaft holes on the left and right sides 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] As can be seen from the above, the above-mentioned existing ink-jet printer ink cartridge carrying device and its printing process obviously have inconvenience and defects in actual use, and need to be improved.
