Detailed implementation manners

[0022] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1 to 4 , the present invention provides a technical solution: a preparation device for a detection spraying table of a new type of powder coating, including a spray cabinet 1. Support legs 17 are provided at the four corners of the bottom of the spray cabinet 1. One side of the spray cabinet 1 is an opening, and a three-axis planar robot parallel thereto is provided at the opening. As Figure 1 and Figure 2 shown, the structure of the three-axis planar robot specifically includes a vertical frame 8. The vertical frame 8 is located at the side of the opening. The two ends of the vertical frame 8 are respectively arranged on the first guide rail 6 through sliders, and the two first guide rails 6 are respectively installed on the upper and lower sides of the opening. A first linear drive module 3 parallel to the first guide rail 6 is provided on the top of the spray cabinet 1. The first linear drive module 3 is connected to the top of the vertical frame 8. Driven by the first linear drive module 3, the vertical frame 8 can horizontally move laterally along the first guide rail 6;

[0024] A second guide rail 7 and a second linear drive module 9 perpendicular to the downward direction are provided on the surface of the vertical frame 8. A slide seat 26 matching the second guide rail 7 is provided on the second guide rail 7. The slide seat 26 is connected to the second linear drive module 9. Driven by the first linear drive module 3, the slide seat 26 can vertically move up and down along the second guide rail 7;

[0025] A horizontal base 27 is provided on the side of the sliding base 26. One end of the horizontal base 27 extends outside the side of the sliding base 26, and a telescopic mechanism 12 with a telescopic direction towards the inside of the spraying cabinet 1 is installed on the horizontal base 27. The telescopic mechanism 12 is a cylinder, an electric telescopic rod or an electric cylinder. A bracket 35 is installed at the free end of the telescopic mechanism 12. The end of the bracket 35 is "L"-shaped and bent. A nozzle 33 is installed inside the end of the bracket 35. Here, the nozzle 33 can be driven by the telescopic mechanism 12 to extend into the inside of the spraying cabinet 1, and the nozzle 33 can move horizontally left and right under the drive of the first linear drive module 3, and the nozzle 33 can move up and down under the drive of the second linear drive module 9. Finally, the nozzle is driven by the telescopic mechanism 12 to advance and retract towards the inside of the spraying cabinet 1, so that the nozzle 33 can reach any point inside the spraying cabinet 1;

[0026] As described above, the free end of the three-axis planar robot can drive the nozzle 33 to reach any point inside the spraying cabinet 1. In the actual application process, the nozzle 33 is used to spray powder coatings, such as Figure 4 shown. Specifically, the inlet of the nozzle 33 is connected to one end of the installation pipe 29 through a pipeline. The other end of the installation pipe 29 is connected to the high-pressure gas supply device 21 through a pipeline. The middle of the installation pipe 29 is connected to the outlet of the solenoid valve 31. A suction pipe 34 is installed at the inlet of the solenoid valve 31. The inlet of the solenoid valve 31 is detachably connected to the bottle mouth of the paint storage bottle 28. Specifically, an annular seat 30 is provided at the inlet at the bottom of the solenoid valve 31. The annular seat 30 is located below the horizontal base 27. The solenoid valve 31 can be fixed by setting it on the top of the horizontal base 27. The bottle mouth of the paint storage bottle 28 is threadedly connected to the inside of the annular seat 30, and then the suction pipe 34 is placed inside the paint storage bottle 28;

[0027] The paint storage bottle 28 is used to store powder coatings. The high-pressure gas supply device 21 is a high-pressure gas station or a high-pressure delivery pump. When the high-pressure gas supply device 21 discharges high-pressure gas, the gas enters the installation pipe 29 through the pipeline, and then the air flow in the installation pipe 29 flows into the nozzle 33 through the pipeline. Since the air flow in the installation pipe 29 quickly passes through the top of the suction pipe 34, according to Bernoulli's principle, the air flow rate in the installation pipe 29 is fast and the pressure is low. Under the action of air pressure, the suction pipe 34 will quickly suck up the powder coatings in the paint storage bottle 28, and then evenly spray out from the end of the nozzle 33 along with the air flow. When the solenoid valve 31 is closed, the nozzle 33 stops spraying paint.

[0028] Corresponding to the nozzle 33, a frame body for supporting the attachment plate 25 is provided inside the spraying cabinet 1. The telescopic direction of the free end of the three-axis planar robot is towards the inside of the spraying cabinet 1, that is, the three-axis planar robot can drive the nozzle 33 to walk at the side of the attachment plate 25. Such as Figure 4As shown, the frame supporting the attachment plate 25 includes at least one horizontal support rod 10. Both ends of the support rod 10 are connected to the inner wall of the spraying cabinet 1. At least one strip-shaped support plate 11 is installed on the support rod 10. The attachment plate 25 is arranged on the surface of the support plate 11. At the same time, a hanging protrusion 24 is provided at the top of each support plate 11, and a hook is provided at the top of the attachment plate 25, and the hook is hung on the hanging protrusion 24;

[0029] The attachment plate 25 is perpendicular to the nozzle 33. When the nozzle 33 sprays air flow, the spraying direction of the powder coating is perpendicular to the attachment plate 25. Therefore, during painting, the attachment plate 25 will not fall or shake and always stably remains on the support plate 11. The nozzle can spray paint on multiple attachment plates 25 under the drive of the three-axis planar robot. After painting is completed, the paint adheres to the surface of the attachment plate 25, and then the operator can take out the attachment plate 25.

[0030] The advantage of storing the powder coating inside the paint storage bottle 28 in the present invention is that, firstly, the paint storage bottle 28 is convenient to disassemble, which is not only convenient for cleaning, but also can store different powder coatings after cleaning, that is, different powder coatings can be tested;

[0031] Secondly, it is convenient to clean the nozzle 33. When the paint spraying is completed and the electromagnetic valve 31 is closed, the powder coating can be prevented from continuing to spray out of the nozzle 33. At this time, after allowing the nozzle 33 to spray high-pressure air flow for a period of time, the powder in the nozzle 33 and the pipeline can be completely removed.

[0032] Furthermore, the present invention further includes an exhaust device which is arranged on the spraying cabinet 1 to quickly discharge dust. The exhaust device includes a suction hood 2 arranged on the top or side of the spraying cabinet 1. The middle of the suction hood 2 is connected to the inlet of the exhaust fan 4, and the outlet of the exhaust fan 4 is connected to the dust filter 16 through a pipeline;

[0033] Figures 1 to 3 The suction hood 2 in is installed on the top of the spraying cabinet 1, such as at the position of the dotted line frame shown in Figure 3 It is also possible to install the suction hood 2 at the position of the dotted line frame. No matter where the suction hood 2 is installed on the surface of the spraying cabinet 1, as long as it can quickly discharge the dust generated during painting, dust overflow can be avoided.

[0034] Furthermore, as shown in Figure 1 and Figure 3 shown, an installation plate 18 is provided below the spraying cabinet 1. The edge of the installation plate 18 is connected to the support leg 17. The high-pressure gas transmission device 21 and the control component are both arranged on the installation plate 18;

[0035] The control component includes a control cabinet 19 arranged on the mounting plate 18. A controller is provided inside the control cabinet 19. The controller is a PLC logic controller or a host computer. The controller is electrically connected to the three-axis planar robot, the air extraction device, and the high-pressure gas transmission device 21 respectively. Specifically, the controller is electrically connected to the first linear drive module 3, the exhaust fan 4, the second linear drive module 9, the telescopic mechanism 12, the high-pressure gas transmission device 21, and the solenoid valve 31 respectively.

[0036] Furthermore, during the operation of the nozzle, a large amount of powder will adhere to the inner wall of the spraying cabinet 1, and all this powder needs to be cleaned. Therefore, the outlet of the high-pressure gas transmission device 21 is also connected to a dust removal spray gun 14 through a pipeline. The dust removal spray gun 14 is placed in a placement rack 15. The placement rack 15 is arranged on one side of the opening of the spraying cabinet 1. When the entire painting process is completed, the operator can hold the dust removal spray gun 14 by hand, and let the airflow ejected from the dust removal spray gun 14 clean the inner wall of the spraying cabinet 1. As Figure 2 and Figure 3 shown, a material equalizing hopper 13 is provided at the bottom of the spraying cabinet 1. A discharge channel 22 is provided below the material equalizing hopper 13. An equalizing container 20 is provided below the discharge channel 22. The equalizing container 20 is placed on the mounting plate 18, so that the dust that falls after cleaning passes through the discharge channel 22 and falls into the equalizing container 20 for storage;

[0037] It should be noted that electric control valves are respectively provided on the pipeline connecting the high-pressure gas transmission device 21 and the dust removal spray gun 14, and on the pipeline connecting the high-pressure gas transmission device 21 and the mounting pipe 29. The electric control valves are respectively electrically connected to the controller.

[0038] Furthermore, a mounting seat 32 is installed at one end of the bracket 35 close to the telescopic mechanism 12. A guide rod 36 parallel to the telescopic mechanism 12 is installed on the mounting seat 32. The guide rod 36 is movably placed in a guide seat. The guide seat is arranged at the bottom of the horizontal seat 27. The provided guide rod 36 can keep the nozzle 33 stable all the time and prevent the nozzle 33 from deflecting.

[0039] Based on the above embodiments, it can be further optimized. Support platforms 23 extending outward horizontally are respectively provided on the upper and lower sides of the opening end of the spraying cabinet 1. The ends of the support platforms 23 are connected together by a reinforcing frame 5, which can enhance the support strength of the upper and lower support platforms 23;

[0040] As Figure 1 and Figure 2 shown, the first linear drive module 3 and the first guide rail 6 are respectively extended and arranged on the support platform 23. In this way, when the vertical frame 8 and the nozzle 33 are not in use, they stay outside one side of the spraying cabinet under the drive of the first linear drive module 3, and the opening of the spraying cabinet is completely exposed, which is convenient for the operator to clean the inside of the spraying cabinet.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
