Embodiment

Below in conjunction with accompanying drawing shownschematically most preferred embodiment be described in further detail.

As shown in Figure 1, a kind of novel 3D printer material volume pick-up unit, comprise physical construction and control circuit, physical construction is by expecting volume 1, material axle 3, bearing 6 and substrate 5 are formed, material volume 1 is provided with hole, material axle 3 runs through material volume 1 by the hole on material volume 1, material axle 3 is fixed on bearing 6 by the shaft shoulder at two ends, bearing 6 front middle part is provided with a boss, boss is fixed with substrate 5, substrate 5 is provided with coil, bearing 6 front upper part has been connected by screw spring leaf 4, material volume 1 is wrapped material silk 2, the movable end of material silk 2 is connected to the charging aperture of 3D printer by the aperture on spring leaf 4.

Described control circuit comprises power module 7, single-chip microcomputer 8, sensor 9, the MOSI of single-chip microcomputer 8, MISO, SCLK, RB0, INT, the SDI of CLK pin and sensor 9, SDO, SCLK, CSB, INTB, TBCLK pin correspondence is connected, the INA of sensor 9, electric capacity C1 is provided with between INB pin, the two ends of electric capacity C1 are connected with the two ends of coil on substrate 5, the CFA of sensor 9, electric capacity C2 is provided with between CFB pin, the VCC of power module 7, the VCC of GND port and single-chip microcomputer 8, the VCC of GND and sensor 9, GND port correspondence is connected, the pause button of 3D printer is connected with between the RA0 port of single-chip microcomputer 8 and the GND port of single-chip microcomputer 8, startup button is provided with between the RA1 port of single-chip microcomputer 8 and the GND port of single-chip microcomputer 8, be provided with between the RA2 interface of single-chip microcomputer 8 and the GND port of single-chip microcomputer 8 and stop key.
