The specific embodiment
Like Fig. 1 to the cup that revolves shown in Figure 6; Air motor connects screw 1 and revolves glass cup 2 design mix body structures (and guarantee the overall structure symmetric design, guarantee to revolve the dynamic balancing effect of cup under the high speed rotation status, meet dynamic balancing measurement standard (ISO1940)); Wherein air motor is provided with through hole (for hollow design) in the middle of connecting screw 1; Middle inner surface is provided with air motor retaining thread 3 in order to connect screw inlet 6, and the outer surface design connects screw external screw thread 4; Wherein revolve glass cup 2 and (revolve the whole aluminum material that adopts of cup; Structure is light; Global design meets dynamic balancing measurement standard (ISO1940)) the middle stepped through hole (being that the cup indoor design is stepped hollow) that is provided with; The upper end inner surface has designed with connecting the cup internal thread 5 (screw thread and cup internal thread that air motor connects screw are 2A/2B level screw thread, and diameter tolerance is 0.005mm) that screw external screw thread 4 matches, and the bottom has been designed with connecting the less cup inlet 7 of diameter that screw inlet 6 is connected; The end is a umbrella; At cup inlet 7 center correspondence positions cone-shaped deflection plate 8 is set, its tip evenly is provided with the fluid hole 9 that diameter is 1.0mm ± 0.2mm towards cup inlet 7 at the edge of deflection plate 8; The bottom radius R that revolves glass cup 2 is 35mm-40mm (makes drop in revolving glass high speed rotary course, have enough strokes to obtain higher linear velocity, make the atomization of liquid more abundant), revolves a glass cup bottom inner surface end ray 10 is set; Its length is 5mm; Width is 0.5mm, and the degree of depth is 0.2mm, and center distance is 1.0mm; Its direction is radial and (this end ray 10: one is set, guarantees that liquid throws away evenly, makes the more atomization of liquid with respect to revolving a glass center; The 2nd, improve anode-cathode voltage; Increase the charged intensity of atomization of liquid particle; Make more atomizing particle can reach surface of the work and carry out adventitious deposit, the transfer efficiency that improves liquid reaches 70-95% (transfer efficiency of conventional air spraying has only 30-50%), has improved production efficiency; And saving processing cost), as shown in Figure 1; The spacing of fluid hole 9 is 0.6mm ± 0.2mm, and the direction of fluid hole is parallel with the inwall that revolves glass cup, the central axis of fluid hole with revolve glass distance L of cup inner face and be 1.0mm ± 0.1mm, as shown in Figure 2; Revolving a glass inclination angle, cup bottom 16 (the angle angle of cup inner face and horizontal plane) is 18 °-20 °, both can guarantee the atomizing effect of liquid, has reduced the splash waste of liquid again, as shown in Figure 3; Air motor connects two lockings of screw 1 outer surface upper end design with plane 15, is convenient to make air motor and is connected screw assembling connection, shown in Fig. 4-1, Fig. 4-2, Fig. 4-3 and Fig. 4-4; During assembling, air motor connect connection screw external screw thread 4 on the screw 1 with the cup internal thread that revolves glass cup 25 butt joints screw to be combined into and revolve cup, as shown in Figure 5; Lock during use with plane 15 and link to each other the air motor retaining thread 3 of air motor connection screw 1 with air motor connecting axle 18; Resistance solder paste China ink 13 gets into along feed liquor direction 11 and connects screw inlet 6; Get into through cup inlet 7 again and revolve in the cup,, revolve cup with rotation at a high speed along with the drive of air motor; After resistance solder paste China ink 13 ejects from fluid hole 9; Owing to revolve the at a high speed centrifugal action that produces of rotation of cup, resistance solder paste China ink forms a resistance solder paste China ink film 14 along jet direction 12 revolving glass inwall, and resistance solder paste China ink film 14 arrives when revolving glass cup 2 ends; Because it receives the splitting action of cup end forceful electric power field force, further atomizing is resistance solder paste China ink particulate 17.Meanwhile; Resistance solder paste China ink particulate 17 has also obtained negative electrical charge, becomes the negative electrical charge particulate, and the particulate crowd neutralizes to the printed board workpiece absorption of positive polarity rapidly under the effect of electric field force; So resistance solder paste China ink just firmly is adsorbed on the printed board surface of the work, like Fig. 1, Fig. 5, shown in Figure 6 equably; Because the high speed rotating of air motor; The air motor retaining thread 3 that is connected screw 1 with air motor be easy to impaired and cause bad connection or dynamic balancing defective; Just can change air motor this moment connects screw 1 and needn't save the spare part cost, shown in 1 revolving all replacings of cup.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
