Module includes machining control module and exposure control module, includes many materials processing and changes groove algorithm and change mask algorithm.On
The Z axis translation mechanism stated is fixed in frame, perpendicular with frame datum plane.It is fixed with the support of table on Z axis translation stage.
Connect on the above-mentioned support of table and have exposure position center adjustment mechanism and workbench manual teardown mechanism.Exposure
The effect of place-centric governor motion be can according to subregion feeder channel to regulate the exposure center of workbench, be allowed to not with feed
Groove produces collision.Workbench manual teardown mechanism act as after process finishing, manually unclamps fastening hand screw, will
Workbench with processing part is pulled down, and conveniently observes and take off the part processed.
Above-mentioned multi partition rotary material groove mainly comprises two parts, rotating mechanism and subregion feeder channel.Whirler
Structure drives a pair spur gear to realize the rotation of subregion feeder channel by motor, and subregion feeder channel comprises three subregions, is respectively
Bi-material subregion and cleaning subregion.In cleaning subregion, include cleanout fluid, when upper a kind of materials processing completes, be switched to
Before lower a kind of materials processing, step to be carried out.The step for completed by three sub-steps, respectively: scrub, soak,
Dry up, carry out the processing of lower a kind of material the most again.Wherein brush step is carried out by cleaning steering wheel band electric brush, and soaking step is by work
Station is immersed in cleanout fluid with the part processed and completes, and dries up step and is dried up fan by two and complete.Whole clearly
Washed journey is completed by distance measuring sensor with the synchronization of the course of processing, the position of distance measuring sensor perception workbench, works as work
Platform is close to behind setting position, and cleaning starts, and after workbench leaves, cleans and enters waiting state.Clean steering wheel, range finding sensing
Device, dry up fan and be all fixed on the cleaning subregion of subregion feeder channel.
Above-mentioned exposure module is arranged on below three partition type swivelling chutes, corresponding to workbench exposure center.Exposure module
It is connected with main control computer by serial ports and HDMI, according to the mask image that the exposure of mask handoff algorithms is different.
The overall axonometric drawing of the present invention increases material manufacture device, tool as it is shown in figure 1, the exposure of slot type many material face is changed in this rotation
Having Z axis translation mechanism 1, it is fixed in frame, perpendicular with frame datum plane.Z axis translation mechanism 1 is fixed with workbench and props up
Frame 12.It is fixed with on the support of table 12 connection and has exposure position center adjustment mechanism 2 and manual teardown mechanism 3.
Such as Fig. 2, the effect of center adjustment mechanism 2 is the exposure center of regulation workbench 11 so that workbench 11 not with point
District's feeder channel 10 produces collision, when after the subregion feeder channel 10 changing different size, can readjust.Manual teardown mechanism 3
Act as after process finishing, by unclamping fastening hand screw, will pull down with the workbench 11 of processing part, convenient see
Examine and take off the part processed.
Such as Fig. 3, subregion feeder channel 10 comprises three subregions, is material one subregion 13, material two subregion 14 and cleaning respectively
Subregion 7.In cleaning subregion, include cleanout fluid, when upper a kind of materials processing completes, before being switched to lower a kind of materials processing,
Step to be carried out.Clean steering wheel 6, distance measuring sensor 5, dry up fan 4 and be all fixed on the cleaning subregion 7 of subregion feeder channel 10
On.
Such as Fig. 4, cleaning step is completed by three sub-steps, respectively: scrubs, soak, dry up, and carries out next the most again
Plant the processing of material.Carry out many materials processing needs more conversion materials groove subregion, first change to cleaning subregion, after being carried out more
Shift to another material partition.Wherein brush step is carried out by cleaning steering wheel 6 band electric brush, soaking step by workbench 11 with
The part processed is immersed in cleanout fluid and completes, and dries up step and is completed by drying up fan 4.Whole cleaning process and the course of processing
Synchronization completed by distance measuring sensor 5, the position of distance measuring sensor 5 perception workbench 11, when workbench 11 is close to setting
Location postpones, and cleaning starts, and after workbench 11 leaves, cleans and enters waiting state.
Such as Fig. 5, many materials mask handoff algorithms, for adding man-hour carrying out different materials, is changed to respective material model automatically
Mask queue and corresponding mask, when carrying out single materials processing, be then changed without mask queue.Add man-hour, first to same
The bi-material part of part models respectively, more respectively it is cut layer and generate mask process；Secondly by two mask teams
Row import.Determine and whether contain bi-material in sustained height is layered, if containing, this layer carries out the first material and adds
Work, is then carried out and changes groove action, then carry out the second materials processing；As do not contained, then this layer carries out respective material
Single materials processing.In the processing of same layer multiple material and different layers different materials are processed, automatically carry out machined part
Cleaning step, to ensure that multiple material does not pollutes.In the processing of same layer multiple material and different layers different materials are processed, from
The dynamic cleaning step carrying out machined part.
Such as Fig. 6, many materials photocuring machining control algorithm is made up of three some algorithms, and respectively many materials mask switching is calculated
Method, workbench and swivelling chute motion control arithmetic, cleaning algorithm.Many materials mask handoff algorithms and workbench and swivelling chute move
Control algolithm synchronizes inside program, and workbench and swivelling chute motion control arithmetic and cleaning algorithm are by distance measuring sensor
Synchronize.Three some algorithms coordinate to carry out the control of whole work flow, it is achieved the processing of bi-material.
