Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See Fig. 1, the present invention can the 3D printer of automatic straightening, comprise the nozzle system 5 be arranged on slide rail, the X-axis stepper motor 1 moved in the X-axis direction on slide rail for driving nozzle system 5, and for driving nozzle system 5 on slide rail along the y-axis stepper motor 2 that Y direction is moved, slide rail is provided with leading screw, and X-axis stepper motor 1, y-axis stepper motor 2 drive nozzle system 5 by leading screw.Slide rail and two stepper motors are installed on the fixed mount in 3D printer housing.The nozzle system 5 of printer of the present invention is provided with X-axis laser displacement rangefinder 4 in the X-axis direction of motion, the Y-axis direction of motion is provided with Y-axis laser displacement rangefinder 3, arranges print platform 6 immediately below nozzle system 5.Two stepper motors and two laser displacement rangefinders all connect master control borad, master control borad are integrated with data encoding and memory module.
The present invention has no progeny in printing can the 3D printer antidote of automatic straightening, comprises the following steps:
Step one, set up coordinate system, by the current location of X-axis laser displacement rangefinder 4 with Y-axis laser displacement rangefinder 3 Real-time Collection nozzle system 5, and image data is sent to master control borad;
Step 2, master control borad are by X-axis laser displacement rangefinder 4, the feedback data of Y-axis laser displacement rangefinder 3 with send to X-axis stepper motor 1, the setting data of y-axis stepper motor 2 compares, master control borad is set with nozzle system 5 single step Mobile data, single step Mobile data is error range, if there is difference, be greater than or less than single step Mobile data, then judge step-out;
Step 3, with current X-axis laser displacement rangefinder 4, the feedback data of Y-axis laser displacement rangefinder 3 is benchmark, again establishes coordinate system, and master control borad is to X-axis stepper motor 1, and y-axis stepper motor 2 sends instruction to correct step-out.
When there is step-out in X-axis or Y direction, judge that the principal element of its step-out is that X, the Y-coordinate value that X, Y-coordinate and laser displacement rangefinder that printer master control borad records record there occurs deviation, when the difference of deviation is greater than or less than the data of 3D printer one step, step-out can be judged to be.When the X-coordinate that 3D printer master control borad records and Y-coordinate and displacement lasers find range the data that gather there is deviation time, master control borad adopts the laser image data coordinate of X-direction and Y-direction to be as the criterion immediately, and shower nozzle is moved, coordinate is corrected, the model layers inconsistent phenomenon caused when guaranteeing to avoid step-out.
