Power-off protection device for 3D printer

Abstract

The invention provides a power-off protection device for a 3D printer. According to the power-off protection device for the 3D printer, due to the fact that the device is an external component, the structural complexity of the 3D printer cannot be increased, and installation is convenient; besides, the device is simple in structure, so the device has the advantages of being small in size and low in cost, and the overall size of the 3D printer is small; and moreover, a current control module can adjust the magnitude of the charging current of an energy storage module, so the charging time of the energy storage module is controlled, the energy storage module is not damaged due to too large charging current, and the situation that charging time is long due to too small charging current is avoided.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a power-off protection device for a 3D printer. Background technique [0002] As is known, a 3D printer is mainly composed of a power supply, a main board, a display panel, a motion mechanism, a printing nozzle, and consumables. The main functions of each part are as follows: [0003] Power supply: mainly to convert the AC voltage to DC24V, and provide power for the main board, the motor of the movement mechanism and the printing nozzle; [0004] Main board: the control center of the entire system, responsible for reading the printed model data, reading the setting parameters, driving the motor of the motion mechanism after data processing, controlling the temperature of the printing nozzle, and sending out status data, etc.; [0005] Display panel: the mainstream is touch screen, which is responsible for the display of status data and the input of setting parameters; [0006]...

AI Technical Summary

Problems solved by technology

[0009] Generally speaking, the current mainstream 3D printers use high temperature to melt various consumables into filaments and stack them into various shapes under the motion mechanism, and finally become printed model works. However, due to the slow printing speed of this type of printer, it usually requires Therefore, when there is an abnormal power failure during the printing process, the movement mechanism suddenly loses power, and it will run for a certain distance under the action of inertia, and a small amount of consumables will flow out of the nozzle, which will form a small bag on the model. The printed model works have defects; in addition, the running data may not be saved in time, which will lead to deviations when the power is turned on again, and eventually the printed model works do not match the design and become defective products; the traditional solution is to The 3D printer is equipped with a UPS power supply to solve the problem. When the 3D printer is powered off, the UPS provides power for a period of time to allow the printer to perform pauses and avoid mechanical movements. However, the UPS power supply has high cost, large volume, short life and regular maintenance. and other issues; therefore, in summary, there is a need for a device that is small in size, easy to use and can provide data storage functions for 3D printers that are powered off.
