Abstract
The invention discloses a precise continued printing method and apparatus used under an abnormal 3D printing condition, and equipment. According to the precise continued printing method and apparatus provided by the invention, an abnormity detection module sends an abnormity signal to a master controller when detecting an abnormal condition; the master controller immediately executes a printing stopping instruction and records the abnormity state data of a printer, wherein a coordinate point, printing parameters, printing files and an abnormity type are calculated by using an algorithm according to printed data during abnormity, and the data is stored in a storage module; if the abnormity signal indicates abnormal power failure, a stand-by power source is switched to, and a printing head is shifted by control of a stepping motor driver at the same time so as to prevent after heat of the printing head from burning a model and harming printing quality; cooling of the printing head is waited, and the printer sounds an alarming prompt and enters a standby state; and when abnormity is eliminated, the abnormity state data of the printer is automatically extracted, the printing heat resets through control of the stepping motor driver and is heated, and printing is resumed. The precise continued printing method and apparatus can guarantee that precise continued printing after elimination of abnormity is not influenced even power supplied by the stand-by power source is not sufficient in the process of shifting.

Detailed description of the invention
The present invention is further described for explanation and detailed description of the invention below in conjunction with the accompanying drawings.
It is an object of the invention to the outage condition occurred in 3D print procedure, it is provided that the most continuous printing method of a kind of power-off abnormality processing, improve the stability that 3D prints.In order to realize above-mentioned purpose, the present invention provides a kind of 3D printer, precisely continues including one and beats device, and as shown in Figure 1, this device includes back-up source, power supply automatic switching module, abnormality detection module, master controller, memory module and stepper motor driver.Described power supply automatic switching module is connected with back-up source, main power source and master controller respectively；Described abnormality detection module, is used for detecting abnormal conditions, and sends abnormal signal to master controller, when abnormal conditions are main power source power-off, also sends power switching control signals to described power supply automatic switching module；Described power supply automatic switching module, for the power switching control signals sent according to described abnormality detection module, starting back-up source is that 3D printer is powered；Described main controller is connected with described memory module, for according to described abnormal signal at once perform stop print action command, journal printer abnormality data, and send control signal with control described stepper motor driver make described printhead shift；Described stepper motor driver is for shifting the printhead of 3D printer；Described memory module, is used for storing printer abnormality data；Described master controller, after abnormal releasing, extracts described printer abnormality data from described memorizer, and sends control signal and make described printhead reset to control described stepper motor driver, then adds thermal printer head and continues printing.Wherein, printer abnormality data include stopping currently printing coordinate data, abnormality categorical data (power-off, fracture, get stuck), mimeograph documents data and print parameters data when printing.
The flow chart of the most continuous printing method of the present invention is as shown in Figure 2, when abnormality detection module detects that unusual condition is powered off, switching back-up source, master controller performs to stop printing action command at once, and journal printer abnormality data: calculate coordinate points during power-off according to the data printed by algorithm, these power-off data are saved in inside storage module；, by controlling stepper motor driver, printhead is shifted meanwhile, prevent the remaining temperature of printhead from scorching model, destroy print quality.Wait printhead cools down, and printer enters holding state.After abnormal releasing, extract printer abnormality data, by controlling stepper motor driver, printhead is resetted, add thermal printer head and continue to print.
When unusual condition is fracture, whether described abnormality detection module is finished for the printing materials detecting hopper, when printing materials and being finished, sends abnormal signal to described master controller.Master controller performs same time-out printing, storage printer modes information and printhead shifting function.Here, it is judged that print whether materials are finished, it is to judge to print the threshold value whether materials storage in hopper is preset less than one.
The present invention compared with prior art, has the advantage that and beneficial effect:
1, the present invention uses uninterrupted back-up source electric power system, main controller is made to maintain electricity condition at any time, ensure under main power source off-position, perform pausing operation, accurate calculation goes out power-off coordinate points, power-off data are saved in memorizer, restore electricity that realization is automatically continuous beats realizing main power source.Improve the stability of 3D print system.
2, the present invention is using battery as back-up source, provides power for removing printhead after power-off, prevents the remaining temperature of printhead from scorching model, destroy print quality.
3, the accurate coordinate when present invention uses algorithm to calculate power-off, to realize the traceless linker of controlling cashier power-cut-off contiuous printing.On this basis, outage detection can be applied equally with fracture detection, get stuck detection and various abnormality detection, can realize printing continuous beating etc. of halfway reloading.
4, switch back-up source after power-off and record power-off coordinate, meanwhile, printhead being shifted (even if in shifting process, back-up source electricity shortage nor affects on).In the case of the benefit of do so prevents back-up source electricity shortage exactly, still can continue that next time precise positioning is continuous beats (have recorded power-off coordinate).
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
