3D printing device based on internet-of-things

Abstract

The invention relates to a 3D printing device based on internet-of-things, which includes: a cabinet body, a cabinet door, a printing mechanism, a self-locking mechanism, a workbench, and a central control mechanism. The self-locking mechanism includes a fixed shaft, a first gear, a second gear, a transmission rod, and a self-locking assembly. The self-locking assembly includes a third gear, a rotating disc, a connecting rod, and a self-locking rod. A work power supply module includes a work power supply circuit. The work power supply circuit includes an integrated circuit, a first capacitor, a second capacitor, a toggle switch, a first resistor, a second resistor, and an adjustable resistor. The model number of the integrated circuit is LM2931. The 3D printing device based on internet-of-things can achieve reliable sealing connection between the cabinet body and the cabinet door through the self-locking mechanism, so that printing reliability of the 3D printing device is improved. In addition, in the work power supply circuit, by means of sampling feedback to output voltage and then adjustment on resistance value of the adjustable resistor, stable adjustment on voltage of the work power supply is achieved, thereby improving the practicability of the apparatus.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a 3D printing device based on the Internet of Things. Background technique [0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even Print the shape of any desired item for the astronauts in the spaceship. [0003] On February 3, 2016, Lin Wenxiong's research group from the 3D Printing Engineering Technology Research and Development Center of Fujian Institute of Material Structure, Chinese Academy of Sciences broke through the key technology of rapid prototyping of 3D objects that can be printed continuously for the first time in China, and developed a super fast continuous Printed on a digital projection (DLP) 3D printer. The speed of the 3D printer has reached a record 600mm / s, and it can "pull" a three-dimensional object with a height of 60mm from the resin t...

AI Technical Summary

Problems solved by technology

[0004] In the existing 3D printing device, when the device is working, due to the lack of a reliable cabinet door closing mechanism, it is easy to make the internal temperature unstable, which reduces the reliability of printing; not only that, when the device is working In the process, the internal working power circuit needs to output a stable working voltage, but because the internal working power circuit lacks the ability to adjust the power output, it will affect the practicability of the device.
