Specific implementation mode

It is described in further detail below in conjunction with the most preferred embodiment shown in attached drawing.

As shown in Figure 1, a kind of novel 3D printer material volume detection device, including mechanical structure and control circuit, machinery knot Structure is made of material volume 1, material axis 3, bearing 6 and substrate 5, and material volume 1 is equipped with hole, and material axis 3 runs through material volume 1 by the hole in material volume 1, Material axis 3 is fixed on by the shaft shoulder at both ends on bearing 6, and 6 front middle part of bearing is equipped with a boss, and substrate 5, substrate are fixed on boss 5 are equipped with coil, and 6 front upper part of bearing has been connected by screw spring leaf 4, and material silk 2 is wrapped in material volume 1, expects the movable end of silk 2 The feed inlet of 3D printer is connected to by the aperture on spring leaf 4.

The control circuit includes power module 7, microcontroller 8, sensor 9, MOSI, MISO of microcontroller 8, SCLK, RB0, INT, CLK pin are corresponding with SDI, SDO, SCLK, CSB, INTB, TBCLK pin of sensor 9 to be connected, sensor 9 Capacitance C1 is equipped between INA, INB pin, the both ends of capacitance C1 are connected with the both ends of 5 coil of substrate, CFA, CFB of sensor 9 Capacitance C2, the port VCC, GND of power module 7 and VCC, GND of microcontroller 8 and VCC, GND of sensor 9 are equipped between pin Port, which corresponds to, to be connected, and the pause button of 3D printer is connected between the ports RA0 of microcontroller 8 and the ports GND of microcontroller 8, single Start button, the GND of the RA2 interfaces and microcontroller 8 of microcontroller 8 are equipped between the ports RA1 of piece machine 8 and the ports GND of microcontroller 8 It is equipped with and stops key between port.
