Description
Technical field
The utility model relates to the equipment technical field of 3D printer, is specifically related to a kind of 3D printer with scene protection and controlling cashier power-cut-off contiuous printing.
Background technology
It is a kind of by melting material silk and successively cooling a kind of method of piling up and realizing printing target object that 3D prints.If printer, when a printing large-scale model, power-off occurs, 3D printer can quit work, and the model printed will be scrapped, and again can only again print after energising.So not only waste consumptive material, time expand, and reduce and be printed as power.
Retrieve the invention that the patent No. is 201410190966.6: its outage detection model calling is in external ac power source, and detecting alternating current need, through reduction voltage circuit, cause detection module comparatively complicated; And after its power-off, coordinating displacement module, the method for employing closed-loop control ensures need be equipped with the seamless connection before and after printer model high-power back-up source, realize cost higher.
Retrieve the invention that the patent No. is 201410321541.4: after its printer power-off, the method for scene protection is the coordinate position of record power-down flag, printer head and printer model.But because shower nozzle power-off does not leave printer model, the residual temperature of shower nozzle can scorch model, destroy the quality of printer model.
Therefore a kind of simple, scene protection and controlling cashier power-cut-off contiuous printing function that effective method realizes 3D printer is needed.
Summary of the invention
For solving the problem, the utility model provide a kind of can carry out scene protection after a loss of power and continue after again powering on last time print scheme.
The equipment and technology scheme that the utility model adopts is: a kind of 3D printer with scene protection and controlling cashier power-cut-off contiuous printing function is formed primarily of power module, detection module, control module and driver module.Described power module comprises dc source and energy storage device; Described dc source is executive circuit power supply and logical circuit power by external communication electricity step-down rectifier; Described executive circuit power supply is responsible for powering to described driver module, and described logical circuit power is responsible for powering to described voltage detection module and described control module; Described energy storage device a is connected to described driver module, but disconnects with described driver module in normal state; Described energy storage device b is connected to described control module.After described detection module is connected to described executive circuit power supply.
Under "on" position, described dc source is powered to detection module, control module and driver module.Once power-off, because described executive circuit power is large, electric discharge is fast, described executive circuit power supply voltage in 1 second just there will be decline, and the electric energy endure about 10 seconds that described logic circuit is provided by described energy storage device b.Described voltage detection module sends rapidly power-off signal to described control module after executive circuit voltage drop being detected, described control module closes the output of described driver module immediately, then state during power-off is saved in the built-in nonvolatile memory of control module, then open described energy storage device a to power to described driver module, drive platform to decline and open and extrude shower nozzle fan shower nozzle is lowered the temperature.
Compared with background technology, the beneficial effects of the utility model are embodied in: 1. have employed the 3D printer that this has power-off scene protection and controlling cashier power-cut-off contiuous printing function, the off-position of external power source can be detected and control 3D printer switches to power-off protection state fast, thus printing last time after printer is energized again, can be continued, avoid the waste of consumptive material, time-write interval, improve and be printed as power; 2. detection module is connected to the power supply state that executive circuit power supply can detect in time external power source, and without the need to downconverter module, circuit is simple, effective; 3. power-off platform declines and model can be avoided to be extruded shower nozzle scald, the seamless connection that just can ensure before and after printer model without the need to coordinating displacement module, and structure is simple; 4. shower nozzle fan unlatching cooling spray can effectively prevent the gob from leaking the impact caused model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of 3D printer with scene protection and controlling cashier power-cut-off contiuous printing of the utility model.
Detailed description of the invention
In order to technology contents of the present utility model can be expressly understood, illustrate especially exemplified by following instance.
Consult shown in Fig. 1, the utility model discloses a kind of 3D printer with scene protection and controlling cashier power-cut-off contiuous printing and be made up of power module 1, voltage detection module 4, driver module 7 and control module 8.
Consult shown in Fig. 1, dashed region is the outage detection module of this utility model, comprises voltage detection module 4, energy storage device a5 and energy storage device b6.Voltage detection module 4 is connected to executive circuit power supply 2(24V) on, energy storage device a5 is connected on driver module 7, and energy storage device b6 is connected in control module 8.
Consult shown in Fig. 1, power module 1 comprises dc source and energy storage device, and dc source comprises executive circuit power supply 2 (24V) and logical circuit power 3(5V), energy storage device comprises energy storage device a5 and energy storage device b6.
When power module 1 is in power supply state, the executive circuit power supply 2(24V of power module 1 step-down rectifier needed for 3D printer) and logical circuit power 3(5V), executive circuit power supply 2(24V) power to driver module 7, logical circuit power 3(5V) power to voltage detection module 4 and control module 8.
When power module 1 disconnects, because of executive circuit power supply 2(24V) power is large, electric discharge is fast, executive circuit power supply 2(24V) in 1 second, voltage will decline, and logical circuit power 3(5V) provide electric energy endure about 10 seconds by energy storage device b6, voltage detection module 4 detects executive circuit power supply 2(24V) send rapidly power-off signal to control module 8 after voltage drop; Control module 8 closes the output of driver module immediately, then state during power-off is saved in the built-in nonvolatile memory of control module, then opens energy storage device a5 and powers to driver module 7, drives platform decline 5mm, prevents model from being scalded by shower nozzle; And open shower nozzle fan, rapid cooling spray, prevent shower nozzle silk gob from leaking damage model.
After 3D printer re-powers, the off-position information in control module 8 reading non-volatile storage, can recover to print from interrupt status.
