Background technology
3D printing technique originates from the RP technique (RapidPrototyping, RP) occurred the eighties in 20th century.RP technique, also known as free forming technology (FreeformManufacturing, FM).Its general principle belongs to addition manufacture (AdditiveFabrication, AF), neither adopt traditional machining tool and mould, according to three-dimensional computer Computer Aided Design (CAD) model of workpiece, under the control of the computer by free forming machine direct forming 3 D workpiece.It combines the multiple advanced technologies such as CAD, numerical control, material, is a kind of subversive manufacturing technology.Its general principle is, computer software is utilized to carry out hierarchy slicing process to cad model, obtain the two-dimensional silhouette information of each bed boundary, G-code control routine is generated according to profile information, fast forming machine is according to control command, and stratified sedimentation material, forms a series of two-dimensional section lamella, last fast forming machine makes mutually to bond between lamella and lamella, by these thin slices progressively laminated structure be piled into 3 D workpiece entity.Because addition autofrettage is by the three-dimensional conversion to two dimension, the shaping of workpiece is made to become simplification, only need the man-hour of traditional machining 30%-50% and the cost of 20%-35%, just directly can make complicated 3 D workpiece, cause huge repercussion in machinery manufacturing industry.
At present, need to use shower nozzle in printer, control to be the guarantee that material is extruded smoothly to the temperature at shower nozzle place, according to the difference of material, printhead heating chamber needs the temperature range of maintenance also different.Only have and the temperature of heating chamber is remained on the temperature that material is just in molten state, material just can be sprayed uniformly.If temperature is too high, may there is the phenomenon of " wire drawing " in nozzle discharge hole, and part top layer also has and because temperature is too high, deformation may occur; If temperature is too low, the material being just ejected nozzle solidifies instantaneously.Current shower nozzle drive system needs further perfect.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of novel 3D printer shower nozzle drive system.
The utility model is achieved through the following technical solutions:
A kind of novel 3D printer shower nozzle drive system, comprise the shower nozzle needing to carry out drived control, also comprise shower nozzle joint module, power amplifier module, D/A modular converter, FPGA module, serial communication modular and Arduino module, the output of described Arduino module is connected with the input of described serial communication modular, the output of described serial communication modular is connected with the input of described FPGA module, described FPGA module is connected with D/A modular converter, described D/A modular converter is connected with power amplifier module, described power amplifier module is connected with shower nozzle joint module, described shower nozzle joint module is connected with shower nozzle, described FPGA module is connected with the two-way communication of shower nozzle joint module.
Further, the I/O voltage in described FPGA module is 3.3V.
Further, described serial communication modular adopts SCSI68 BITBUS network Interface realization differential transfer.
D/A modular converter converts the data signal from FPGA to analog signal, and the numeric string by high tension ignition pulse signal converts the analog signal waveform of high tension ignition pulse to.
The level signal exported from FPGA module is LVTTL type, output to shower nozzle also to need to carry out again the signal that level conversion will change and comprise clock signal C lk, load signal Load, synchronizing signal Stb and print data, drive the high tension ignition pulse signal of shower nozzle igniting to be also input to this module in the lump after power amplifier module amplifies.
Compared with prior art, the beneficial effects of the utility model are: the FPGA module in the utility model can work under the frequency clock of hundred megahertzes, more accurate signal can be produced, FPGA module also can guarantee the accuracy of each signal sequence simultaneously, the precision and stability of whole shower nozzle drive system can be improved, be convenient to promote the use of.
