Control system, by detecting the pulse signal of grating module A, B phase, obtains true relative displacement and the direction of two gratings.When grating scale is fixed on machine frame, grating head is moved along with displacer, can obtain the accurate mechanical displacement information of slide block.In XY motion, by the compensation of closed-loop control, can realize the precise synchronization motion of slide block, fluidity of motion and accuracy are provided.

(1) detection of the direction of motion

The phase place of supposing A, the pulse of B phase is respectively the A phase pulse of take is reference, and an orientation left side is positive direction,

If slide block is to left movement;

If slide block moves right, and with this, detects the direction of motion of slide block.

(2) correction of moving displacement

Take X-axis motion as example, and establishing X-axis motion minimum resolution is p mm, and stepper motor often makes a move, and slide block moves p mm.Suppose that certain motion control process need slide block displacement is S, if adopt open loop to control, can directly calculate required stepper motor motion step number and be:

N = S p

If the pitch of grating scale is d, the required grid number of passing by of slide block displacement S is:

M = S d

When control step motor is passed by after step number N, by pulse count, can obtain the actual grid of passing by of slide block and count m, the pitch of often passing by, umber of pulse adds 1.

Ideally, m=M, but because the error of open loop control exists, actual m ≠ M.

When m < M, need to increase stepper motor motion step number, correction formula is:

N &prime; = N + &Delta;N

= S p + ( M - m ) d p

When m > M, need to reduce stepper motor motion step number, correction formula is:

After correction, can record the actual grid of passing by of slide block and count m '=M, thereby accurately control slide block displacement S.

(3) XY motion closed-loop control

As shown in Figure 8, in XY motion of the present utility model, " mouth " font structure that requires four optical axises to form is mutually vertical with two " ten " word center spindle structure, take and guarantees that X, the Y-direction of kinematic system are desirable vertical relation.But due to the existence of the factors such as machine error, motor desynchronizing, belt stretch, may there is not exclusively vertical situation in these two structures.

Suppose two " ten " word axles and ideal position difference angle δ, in certain motion, only control X-axis moving displacement S x, as shown below.Due to the existence of error angle δ, the motion of the single shaft of X-axis, by the coupling of central slider, can cause Y-axis to produce corresponding side-play amount:

Δy=S xgsinδ

When adopting open loop control mode, this side-play amount cannot detect, and also cannot eliminate.The introducing of closed-loop control, can be detected by the grating of Y-axis this side-play amount, thereby revises in real time by closed loop control algorithm.When Y-axis is carried out single shaft motion and caused X-axis skew, also can by the grating of X-axis, detect and revise.

Like this, just can be to compensating due to the displacement error that belt is flexible, the unequal reason of electromechanics step pitch causes, thus realize the accurate control of XY motion, greatly improve fineness, uniformity and the reliability of printing.

The control system block diagram of 3D printer of the present utility model as shown in Figure 9.The three-dimensional modeling data that need to print is converted to G code by hierarchy slicing software, then through print control program, is transmitted or directly by SD card, read by USB port.Master controller mainly carries out communications protocol processing, command interpretation, encoder decoding, motion control arithmetic realization, Electric Machine Control, temperature control and human-computer interactive control etc.The wherein motion of X, Y, Z Electric Machine Control three-dimensional mechanism, E1, E2 motor are controlled respectively first and second wire feeders.The actual position information of X, Y, Z reads by grating encoder, and feeds back to master controller, realizes the three-dimensional coordinate of closed-loop accurately locate via motion control arithmetic and closed loop control algorithm.

The temperature of nozzle is read by a K type thermocouple, through amplifier, is converted to the voltage signal that main controller reads.The temperature of nozzle is controlled and is accurately controlled by the PID FUZZY ALGORITHMS FOR CONTROL of main controller inside.Print platform is heated by the heating plate that is arranged on platform below, to improve the adhesive force of model on print platform.The temperature of print platform reads master controller by temperature sensor equally, then by pid algorithm, carries out temperature control.

Refrigerating plant is by the power supply of fan or air pump is regulated to realize Strength Changes, and control signal adopts pulse width modulation (PWM) mode, produces control signal be connected to drive circuit by master controller.The temperature control algorithm of master controller inside, by the feedback of reading temperature sensor, regulates the control signal of refrigerating plant equally, thereby realizes the complete closed-loop control of temperature.
