Description
Technical field
The utility model relates to 3D and prints field, particularly, relates to the circuit protection device for 3D printer.
Background technology
FDM (Fused Deposition Modeling) technique Fused Deposition Modeling technique belongs to a kind of technique that 3D prints, and uses the materials such as PLA, ABS, nylon, by heat fused in printer head.Shower nozzle is along part section profile and fill orbiting motion, and is extruded by the material of fusing, forms 3D printer model.
When 3D printer head be plugged in print procedure or motor by card time, material will be caused normally to extrude.At present based on the 3D printer often plug-in consumptive material on machine of FDM principle, shower nozzle enables consumptive material send into heating head endlessly in order to extruding after thawing by the rotation of motor.But can cause the situation that material cannot normally be extruded for various reasons in print procedure, reason wherein may be that shower nozzle is blocked by impurity, consumptive material is stuck, or extruder motor operation irregularity etc.The consequence that this mistake causes is that shower nozzle can not but still move by extruded material, if can not find as early as possible, shower nozzle will do this insignificant movement until print end always.In fact, model now prints failure, needs to restart.So early can find that the abnormality of shower nozzle is very important.
When the coordinate of shower nozzle movement exceedes the maximum magnitude that printer can allow, printer operation irregularity.Material has been extruded printing in the movement of xyz axle by shower nozzle by the 3D printer at present based on FDM principle in effective coordinate.Generally, the origin of coordinates can be found to help shower nozzle before printing starts by mounting limit device at the min coordinates place of printer xyz, when such shower nozzle moves to the minimum place of any one axle of xyz, limit switch is triggered, control circuit can receive the signal from limit switch, control motor stop motion, but can the point of arrival at the maximum of xyz axle for shower nozzle, for objects such as saving control chip interface resources, generally obtained by the data file of model to be printed, that is the coordinate information inside the model data file that receives of 3D printer can't exceed the maximum magnitude that printer can work, therefore the order received at 3D printer is under correct prerequisite entirely, shower nozzle moving coordinate is there will not be to exceed the situation of maximum magnitude.But in actual moving process, once 3D printer gets muddled or the model file data that receive are wrong, the maximum magnitude that shower nozzle amount of movement can be caused to exceed printer allow, causes printer head move to maximum position and be stuck, and now motor is but still in operation.If can not this situation of Timeliness coverage, motor will burn out because of overheated.
Therefore; propose a kind of self-protection system for 3D printer, carry out Real-Time Monitoring, once there is comparatively grave error for the abnormal conditions often occurred in 3D print procedure; can user be notified as early as possible or cut off the electricity supply, to protect the safety of printing device.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
For a circuit protection device for 3D printer, comprise 3D printer, 3D printer material consumption volume 1, it is characterized in that, also comprise: tongue tube sensor assembly 5, magnetic patch 6, maximum stop, relay; Wherein, described magnetic patch is arranged on 3D printer material consumption volume and 1 presses close on the rotating disk of the outer surface of 3D printer casing 2; Described tongue tube sensor assembly 5 is installed in the inside of 3D printer; Described maximum stop is arranged on the maximum coordinates place allowed when 3D printer prints; The control port that described tongue tube sensor assembly 5 and the output signal of maximum stop can be sent to relay forms control loop, and the switching circuitry of described relay is connected with the power supply of 3D printer.
Particularly, as shown in Figure 1, tongue tube sensor assembly 5, in conjunction with magnetic patch 6, is responsible for whether detecting 3D printer material consumption volume 1 in rotation, if do not receive in the set time turn signal that tongue tube sensor assembly 5 transmits, then think that consumptive material does not continue to send into printer head, buzzer work can be notified, to notify that user processes as early as possible, if user does not take any measure yet, 3D printer material consumption volume 1 without rotation time more than a fixed value time, relay is cut off the electricity supply.In addition, if shower nozzle moving range is more than the maximum of 3D printer defined, maximum stop can be touched, and relay cuts off the electricity supply to protect motor.
Preferably, described tongue tube sensor assembly 5 is positioned on the inner surface of the 3D printer casing 2 corresponding to track formed when described magnetic patch 6 rotates with 3D printer material consumption volume 1.
Particularly, when magnetic patch 6 forwards to tongue tube sensor assembly 5 same position, tongue tube sensor assembly 5 internal circuit can detect that magnetic field exists, the internal circuit of described tongue tube sensor assembly 5 can be communicated with once, whenever 3D printer material consumption volume 1 rotates a circle, tongue tube sensor assembly 5 exports a pulse signal.
Preferably, also comprise buzzer, the control end of described buzzer is connected to tongue tube sensor assembly 5.
Particularly, in normal print process, because consumptive material is sent constantly into shower nozzle, so 3D printer material consumption volume 1 can continue to rotate with very slow speed.Tongue tube sensor assembly 5 and 3D printer material consumption roll up 1 alternating floor 3D printer casing 2, it is each when magnetic patch 6 forwards to tongue tube sensor assembly 5 same position, tongue tube sensor assembly 5 internal circuit is owing to detecting that magnetic field exists, internal circuit can be communicated with, like this whenever the rotation one of 3D printer material consumption volume is enclosed, tongue tube sensor assembly 5 just can export a pulse signal.What the pulse signal exported according to tongue tube sensor assembly 5 inferred whether shower nozzle normally carry out material extrudes operation, if no pulse exports, can first start buzzer work, if do not receive the pulse of tongue tube sensor assembly 5 for a long time, the just direct power supply being cut off 3D printer by relay.
Preferably, described maximum stop comprises: the maximum stop of X-direction 7, the maximum stop of Z-direction 8, the maximum stop 12 of Y direction.
Preferably, described tongue tube sensor assembly 5 be clarinet, the comparator model in described tongue tube sensor assembly 5 is LM393, described tongue tube sensor assembly 5 comprises three ports, one of them positive source, a power cathode, also has a switching signal output.
Particularly, described tongue tube sensor assembly 5 can be tongue tube, adopts tongue tube open type, operating voltage 3.3-5V.
Preferably, described relay is light-coupled isolation No. one relay.
Particularly, use normally closed connection during described relay wiring, during relay adhesive, switch becomes disconnection from original connection, and 3D printer quits work.
Preferably, described maximum stop is XSS-5GL microswitch.
Particularly; maximum stop; need the position finding already installed minimum stop according to concrete 3D printer; to determine the origin of coordinates; the maximum magnitude place allowed at the printer of correspondence more afterwards adds the maximum stop in X-direction, Y direction, Z-direction respectively; like this when 3D printer operation irregularity causes motor removing scope excessive, maximum stop can be triggered, and controller can cut off the electricity supply to protect motor.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
