Therefore, it is necessary to propose a multi-angle directional spraying mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] The utility model provides Figures 1 to 4 The multi-angle directional spraying mechanism shown includes a conveyor belt 1, and two support columns 2 are fixedly installed on the top of the conveyor belt 1, and the top of one of the support columns 2 is rotatably connected to an adjusting rod 3, and a support plate 4 is slidingly arranged between the opposite surfaces of the two support columns 2, and the bottom end of the adjusting rod 3 is threadedly connected to the support plate 4. A liquid storage cylinder 5 is fixedly installed on the top of one of the support columns 2, and a hose 6 is fixedly connected to the bottom of the liquid storage cylinder 5. A visual sensor 7 is fixedly installed on the side of the support column 2 with the adjusting rod 3, and an I-type plate 8 is slidingly arranged on the top of the support plate 4. When in use, the high-frequency board is continuously conveyed by the conveyor belt 1, and the support plate 4 is lifted up and down between the two support columns 2 by rotating the adjusting rod 3, so as to adjust the spraying area according to the size of the high-frequency board. A water pump is provided in the liquid storage cylinder 5, and the paint in the liquid storage cylinder 5 is continuously conveyed to the hose 6 by the water pump.

[0024] The I-shaped plate 8 is provided with an adjustment component, through which the sprayable area can be adjusted at multiple angles, so that high-frequency plates of different sizes and specifications can be sprayed evenly.

[0025] The adjusting component includes a rotating rod 9 rotatably connected to the top of the I-shaped plate 8, and the bottom end of the rotating rod 9 is fixedly connected to a gear 10. The bottom of the I-shaped plate 8 is rotatably connected to a T-shaped turntable 11. A circle of teeth is provided on the side of the T-shaped turntable 11, and the teeth of the T-shaped turntable 11 are meshed with the gear 10. The bottom of the T-shaped turntable 11 is fixedly connected to two rectangular blocks, and the side of one of the rectangular blocks is rotatably connected to a T-shaped nozzle 12. The end of the hose 6 is fixedly connected to the top of the T-shaped turntable 11, and the side of the other rectangular block is threadedly connected to a pressure rod 13. When in use, the height of the T-shaped nozzle 12 can be freely adjusted by rotating the adjusting rod 3, and the T-shaped nozzle 12 can be driven to slide horizontally by pushing the I-shaped plate 8. When the high-frequency plate only needs to spray part of the area, the area where the high-flat plate needs to be sprayed can be accurately sprayed by rotating The rotating rod 9 causes the gear 10 to drive the T-shaped turntable 11 to rotate, thereby adjusting the direction of the T-shaped nozzle 12. By rotating the pressure rod 13, its end is no longer in contact with the T-shaped nozzle 12. At this time, the T-shaped nozzle 12 can be rotated to change the inclination angle of the T-shaped nozzle 12, and then the pressure rod 13 is rotated again to make its end contact with the T-shaped nozzle 12. The inclination angle of the T-shaped nozzle 12 is fixed by the pressure rod 13. Therefore, the steering and inclination angle of the T-shaped nozzle 12 can be adjusted respectively by the rotating rod 9 and the pressure rod 13, thereby achieving multi-angle adjustment. When the visual sensor 7 detects that a high-frequency board is approaching, the water pump in the liquid storage cylinder 5 is controlled to transport the paint to the T-shaped nozzle 12 for spraying, thereby not only the flat surface of the high-frequency board can be sprayed, but also its vertical and inclined surfaces can be sprayed, avoiding dead angles and missing coating, and improving the consistency and quality of the coating.

[0026] like Figures 2 to 3 As shown, a row of positioning holes 14 are provided on the top of the support plate 4, and a positioning rod 15 is movably inserted into the top of the I-shaped plate 8. The bottom end of the positioning rod 15 is located on the inner side of the positioning hole 14, and a spring 16 is movably sleeved on the side of the positioning rod 15. When in use, the position of the T-shaped nozzle 12 can be locked by the positioning rod 15 and the positioning hole 14 to prevent the T-shaped nozzle 12 from being shaken and offset.

[0027] During specific use, one end of the spring 16 is fixedly connected to the I-shaped plate 8, and the other end of the spring 16 is fixedly connected to the side of the positioning rod 15. The spring 16 can prevent the positioning rod 15 from being lost and ensure that the bottom end of the positioning rod 15 is always inserted in the positioning hole 14. By pulling the positioning rod 15 upward to disengage it from the positioning hole 14, the I-shaped plate 8 can be moved. After the movement is completed, the positioning rod 15 is released to insert it into the positioning hole 14 at the corresponding position, thereby locking the position of the I-shaped plate 8 and ensuring that the T-shaped nozzle 12 will not be shaken and offset.

[0028] Furthermore, a row of scale lines 17 is provided on the top of the support plate 4, and the distribution interval of the scale lines 17 is the same as the distribution interval of the positioning holes 14. When in use, the moving distance of the I-plate 8 can be accurately controlled by the scale lines 17, so that the T-shaped nozzle 12 can achieve multi-angle spraying at a precise position.

[0029] like Figure 2 and Figure 4 As shown, the bottom of the T-shaped nozzle 12 is rotatably connected to a disk 18, and a plurality of circular holes of two diameters are provided at the bottom of the disk 18. The bottom of the T-shaped nozzle 12 is also provided with a circular hole. The maximum diameter of the circular hole on the disk 18 does not exceed the diameter of the circular hole on the T-shaped nozzle 12. When in use, the diameter of the liquid particles sprayed by the T-shaped nozzle 12 can be adjusted by rotating the disk 18, thereby realizing switching between large particles and small particles.

[0030] During specific use, the bottom of the disc 18 is provided with circular holes of two diameters, and the distribution intervals of the circular holes of the two diameters are consistent with the circular holes of the T-shaped nozzle 12. The circular holes of different diameters enable the T-shaped nozzle 12 to spray out liquid particles of two sizes. The large-particle paint can cover a large area of ​​the high-frequency board surface more quickly, reducing the coating time and improving the production efficiency. The small-particle paint can be more evenly applied on the surface, ensuring the consistency and smoothness of the coating, especially for the better coverage of the details.

[0031] Furthermore, two positioning blocks 19 are fixedly connected to the side of the T-shaped nozzle 12, and a fixed block 20 is fixedly connected to the side of the disc 18. The fixed block 20 is located between the two positioning blocks 19. By rotating the disc 18, the fixed block 20 is respectively in contact with the two positioning blocks 19. Through the fixed block 20 and the positioning block 19, the circular hole of the T-shaped nozzle 12 and the circular hole of the disc 18 can be quickly overlapped, thereby quickly switching the size of the liquid particles sprayed by the T-shaped nozzle 12.

[0032] Furthermore, a plurality of hooks 21 are fixedly connected to the side of the support plate 4, and the hose 6 is placed on the surface of the hook 21. The hook 21 can limit the hose 6 to prevent the hose 6 from hanging in the spraying area of ​​the T-shaped nozzle 12 and affecting the spraying effect.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
