Penetrate model；
S11, according to the interface of jet model and segmentation mask determine to dust entrance, and it is true according to jet model center line
Surely dust incident direction；
S12, according to dusting, entrance and incident direction of dusting adjust the first electrostatic gun, are dusted to workpiece to be sprayed.
Preferably, in addition to step S13, by the second electrostatic gun to the overall electrostatic dusting of workpiece to be sprayed；First is quiet
The bore of electric spray gun is less than the bore of the second spray gun.
Preferably, the bore of the first electrostatic gun is 1/10th of the bore of the second spray gun, or 1 percent, or two numbers
Arbitrary value between value.
Preferably, gap threshold value is worth more than the first spray gun muzzle section.
Preferably, angle threshold value is 90 degree.
Preferably, in step S1, with infrared light scanning workpiece to be sprayed.
In the present invention, by the first mask, a cladding part model and the smooth curved surface of entire teachings are established, and lead to
Cross the first mask and part model is compound, mark the chamber structure on workpiece.By by setting up the second mask, to workpiece table
The concave structure in face is estimated；The restrictive condition of second mask, is conducive to part model surface relatively depth or is open narrower
Concave structure protrusion.By the way that the first mask and the second mask are compounded to form into assessment mask, by relatively depth on workpiece or open
The narrower chamber structure of mouth is marked.
In the present invention, by step S5-S7, by setting up assessment models, workpiece surface is marked according to assessment mask
Chamber structure is judged, the gap size of chamber structure is judged with assessing the interface of mask by assessment models, by commenting
Estimate the center line of model and judge whether chamber structure is inclined to relative to gap with assessing the angle of line, so that, judge chamber structure
During integral spray powder difficulty.By step S8 and S9, by workpiece surface gap is big and indent direction give comments and criticisms it is straight
Chamber is added in segmentation mask, that is, in the zone of responsibility for adding to integral spray.So as to further reduce the duty finely sprayed
Appoint area, be conducive to improving operating efficiency.
In the present invention, dust entrance and incident direction of dusting are determined according to jet model, are conducive to deeper to workpiece surface
Or the narrower chamber structure of opening dusts, solve on workpiece surface that relatively deep or narrower concave structure is difficult asking for attached powder
Topic.And, the first electrostatic gun is wiped and uses small-bore spray gun, to carry out fixed point injection according to dust entrance and incident direction of speaking rubbish,
Improve the precision of dusting of workpiece surface concave structure.
Brief description of the drawings
Fig. 1 is a kind of electrostatic spraying synergisting method flow chart proposed by the present invention.
Embodiment
A kind of reference picture 1, electrostatic spraying synergisting method proposed by the present invention, comprises the following steps：
