Problems solved by technology

For the existing FDM (Fused Deposition Manufacturing) type 3D printers, the machine cannot automatically detect faults when encountering faults such as wire shortage (or broken wire), wire jamming or wire blocking.
If the operator does not take the initiative to find the fault, the 3D printer will continue to run, which not only wastes working time, but also easily causes 3D printer equipment failure during the process of jamming, shortens the life of the 3D pri

Embodiment Construction

[0022] see figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 , a 3D printer monitoring device, a detector 7, a traction device 6, and a detector 4 are sequentially arranged between a wire tray 8 and an extrusion device 3. The detector 4 / 7 adopts a symmetrical double roller structure, including a driven wheel 10 and a detection roller 12. The detection roller 12 is made of a flexible outer ring with a large friction coefficient, and the wire 5 passes between the two wheels; the detection roller 12 and the Encoder 13 is connected, under normal circumstances, encoder 13 outputs a square wave pulse signal. When the wire feed fails, the wire material 5 will not be conveyed forward, and encoder 13 will stop outputting square waves and become output high / low level. When the counter of the single-chip microcomputer stops working, when the counter stops working within a certain period of time, it can be judged as a wire failure; the encoder 13 is connected to the signal li...

Abstract

The invention discloses a 3D printer monitoring device. According to the 3D printer monitoring device, a detector, a traction device and the detector are arranged between a wire reel and an extrusiondevice in sequence, wherein the two detectors are connected with a control device, one of the detectors monitors wire clamping and wire lacking (or wire breaking) conditions of the wire reel, the other one of the detectors monitors wire blocking and the wire lacking (or the wire breaking) conditions of an extrusion head, when wire feeding failure occurs, the detectors detect abnormity and send abnormal signals to the control device, the control device sends the signals to a 3D printer main control panel, a 3D printer is controlled to stop working temporarily, and remote alarm information is sent to an equipment manager through a short message receiving and sending device. By means of the 3D printer monitoring device, the printer is avoided from working under the wire feeding failure, and remote monitoring and management of the 3D printer can be realized.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a 3D printer monitoring device. Background technique [0002] Research status and development trends: 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. . 3D printing is usually achieved using a digital technology material 3D printer. With the continuous advancement of 3D printing technology, people have put forward higher requirements for the function, performance and reliability of 3D printers. For the existing FDM (Fused Deposition Manufacturing) type 3D printers, the machine cannot automatically detect faults when encountering faults such as wire shortage (or broken wire), wire jamming or wire blocking. If the operator does not take the initiative to discover the fault, the 3D printer will continue t...
