Detailed implementation mode

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in 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.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 7, A direction control device for a high-degree-of-freedom painting robot, including a workbench 1, a conveying device 2 is fixedly connected to the inner wall of the workbench 1, a driving motor 3 is fixedly connected to the bottom of the workbench 1, a transmission shaft 4 is fixedly connected to the output end of the driving motor 3, a paint storage tank 6 is fixedly connected to the top of the workbench 1, a rotating mechanism is fixedly connected to the top of the transmission shaft 4, a conveying pipe 11 is communicated with the side wall of the paint storage tank 6, one end of the conveying pipe 11 is communicated with a heat preservation box 14, the bottom of the heat preservation box 14 is fixedly connected to the top of the workbench 1, a first pressure sensor 16 is fixedly connected to the bottom of the inner wall of the heat preservation box 14, a limiting spring 15 is fixedly connected to the bottom of the inner wall of the heat preservation box 14, a sliding circular plate 17 is fixedly connected to the top of the limiting spring 15, the side wall of the sliding circular plate 17 is slidably connected to the inner wall of the conveying pipe 11, a return spring 18 is fixedly connected to the inner wall of the heat preservation box 14, one end of the return spring 18 is fixedly connected to a second pressure sensor 19, the side wall of the second pressure sensor 19 is slidably connected to the inner wall of the heat preservation box 14, a second heat preservation pipe 20 is communicated with the top of the heat preservation box 14, a control mechanism is fixedly connected to the side wall of the second heat preservation pipe 20, a spraying pipe 34 is communicated with the bottom of the second heat preservation pipe 20, a third electric push rod 32 is fixedly connected to the bottom of the second heat preservation pipe 20, and a limiting cylinder 33 is fixedly connected to the bottom of the third electric push rod 32, and the inner wall of the limiting cylinder 33 is slidably connected to the side wall of the spraying pipe 34.

[0029] It should be noted that when there is equipment that needs to be painted, start the conveying device 2, and the conveying device 2 transports the equipment to the bottom of the limiting cylinder 33. Start the water pump inside the first heat preservation pipe 10, and the water pump inputs the paint inside the paint storage tank 6 into the heat preservation box 14 through the first heat preservation pipe 10. Under the action of gravity, the paint drives the sliding circular plate 17 to press down. The paint on the top of the sliding circular plate 17 gradually increases and continuously drives the sliding circular plate 17 to press down until the sliding circular plate 17 touches the first pressure sensor 16. The first pressure sensor 16 controls the closing of the first heat preservation pipe 10 under pressure and stops inputting paint into the heat preservation box 14, avoiding the paint in the first heat preservation pipe 10 being too much and unable to be used up in time, resulting in the paint solidifying inside the heat preservation box 14. As time goes by, the paint inside the heat preservation box 14 gradually decreases, and the limiting spring 15 drives the sliding circular plate 17 to gradually rise through elasticity until the sliding circular plate 17 rises to the side wall of the second pressure sensor 19. The second pressure sensor 19 controls the start of the first heat preservation pipe 10 under pressure and continues to inject paint into the heat preservation box 14, completing the automatic feeding of the heat preservation box 14 and improving the automation degree of the device;

[0030] Start the water pump inside the heat preservation box 14, and the water pump sprays the paint inside the heat preservation box 14 onto the equipment to be sprayed through the second heat preservation pipe 20. When the second heat preservation pipe 20 sprays the paint, start the third electric push rod 32, and the third electric push rod 32 extends. The third electric push rod 32 drives the limiting cylinder 33 to move to the side wall of the equipment to limit the paint, avoiding the paint from spreading everywhere during spraying and affecting the already sprayed positions.

[0031] In an alternative embodiment: The rotating mechanism includes a first gear 7. The inner wall of the first gear 7 is fixedly connected to the side wall of the transmission shaft 4. A second gear 13 is movably connected to the side wall of the first gear 7. A second electric push rod 12 is fixedly connected to the inner wall of the second gear 13. A third gear 21 is movably connected to the side wall of the second gear 13. The inner wall of the third gear 21 is fixedly connected to the side wall of the second heat preservation pipe 20.

[0032] It should be noted that when the position of the spraying pipe 34 needs to be adjusted, the second electric push rod 12 is started. The second electric push rod 12 extends, and the second electric push rod 12 drives the second gear 13 to rise to the side walls of the first gear 7 and the third gear 21. The driving motor 3 is started, and the driving motor 3 drives the transmission shaft 4 to rotate. The transmission shaft 4 drives the second heat preservation pipe 20 to rotate through the first gear 7, the second gear 13, the third gear 21, the fixed vertical rod 22 and the first limiting plate 23 to expand the working range of the spraying pipe 34. After the second heat preservation pipe 20 finishes rotating, the second electric push rod 12 is started, and the second electric push rod 12 drives the second gear 13 to contract and disengage from the side walls of the first gear 7 and the third gear 21 to prevent the driving motor 3 from driving the third gear 21 to rotate continuously.

[0033] In an alternative embodiment: The control mechanism includes a fixed vertical rod 22. The top of the heat preservation box 14 is rotatably connected to the bottom of the fixed vertical rod 22. The top of the fixed vertical rod 22 is fixedly connected to a first limiting plate 23. A first electric rotating rod 26 is fixedly connected to the inner wall of the first limiting plate 23. A first control chamber 24 is fixedly connected to the side wall of the first electric rotating rod 26. A second electric rotating rod 27 is fixedly connected to the inner wall of the first control chamber 24. A second limiting plate 28 is fixedly connected to the side wall of the second electric rotating rod 27. A third electric rotating rod 29 is fixedly connected to the inner wall of the second limiting plate 28. A second control chamber 25 is fixedly connected to the side wall of the third electric rotating rod 29. A fourth electric rotating rod 30 is fixedly connected to the inner wall of the second control chamber 25. A third limiting plate 31 is fixedly connected to the side wall of the fourth electric rotating rod 30. The inner wall of the second limiting plate 28 is fixedly connected to the side wall of the second heat preservation pipe 20. The inner wall of the third limiting plate 31 is fixedly connected to the side wall of the second heat preservation pipe 20.

[0034] It should be noted that when the angle of the limiting cylinder 33 needs to be adjusted, the angle of the second heat preservation pipe 20 can be rotationally adjusted through the cooperation of the first limiting plate 23, the first electric rotating rod 26, the first control chamber 24, the second control chamber 25, the second electric rotating rod 27, the second limiting plate 28, the third electric rotating rod 29, the fourth electric rotating rod 30 and the third limiting plate 31.

[0035] In an alternative embodiment: A first electric push rod 8 is fixedly connected to the top of the transmission shaft 4. A cleaning steel brush 9 is fixedly connected to the top of the first electric push rod 8.

[0036] It should be noted that when too much paint adheres to the inside of the blocking cylinder 37, the third gear 21 drives the second heat preservation pipe 20 to rotate to the top of the cleaning steel brush 9 through the fixed vertical rod 22 and the first limiting plate 23. The first electric push rod 8 is started, and the first electric push rod 8 drives the cleaning steel brush 9 to extend into the inside of the blocking cylinder 37. The driving motor 3 drives the cleaning steel brush 9 to rotate through the transmission shaft 4 and the first electric push rod 8 to brush the inner wall of the blocking cylinder 37.

[0037] In an alternative embodiment: a stirring blade 5 is fixedly connected to the side wall of the transmission shaft 4, and the side wall of the stirring blade 5 is rotatably connected to the inner wall of the paint storage tank 6.

[0038] It should be noted that the paint inside the paint storage tank 6 can be stirred by the arrangement of the stirring blade 5.

[0039] In an alternative embodiment: a first heat preservation pipe 10 is communicated with the side wall of the paint storage tank 6. One end of the first heat preservation pipe 10 is communicated with the side wall of the heat preservation box 14, and the top of the first heat preservation pipe 10 is fixedly connected to the bottom of the second electric push rod 12.

[0040] It should be noted that the paint is heat-preserved through the arrangement of the first heat preservation pipe 10 to prevent the paint from solidifying due to condensation inside the conveying pipe 11.

[0041] In an alternative embodiment: a connecting rod 35 is fixedly connected to the inner wall of the limiting cylinder 33. One end of the connecting rod 35 is fixedly connected to an electromagnet 36. One end of the electromagnet 36 is movably connected to a blocking cylinder 37. The side wall of the connecting rod 35 is slidably connected to the inner wall of the spraying pipe 34, and the side wall of the electromagnet 36 is slidably connected to the inner wall of the spraying pipe 34.

[0042] It should be noted that when the third electric push rod 32 drives the limiting cylinder 33 to press down, the limiting cylinder 33 drives the blocking cylinder 37 to press down through the connecting rod 35 and the electromagnet 36 to protect the inner wall of the spraying pipe 34, preventing the paint from directly contacting the inner wall of the spraying pipe 34, resulting in the paint solidifying and adhering to the inner wall of the spraying pipe 34, causing the spraying pipe 34 to be blocked, and extending the service life of the spraying pipe 34. When the paint on the inner wall of the blocking cylinder 37 is too much to be cleaned, the electromagnet 36 is turned off to stop adsorbing and fixing the blocking cylinder 37, making it more convenient for the staff to replace the blocking cylinder 37.

[0043] In an alternative embodiment: the longitudinal section of the electromagnet 36 is triangular, and the side wall of the electromagnet 36 is slidably connected to the inner wall of the spraying pipe 34.

[0044] It should be noted that the arrangement of the electromagnet 36 with a triangular longitudinal section prevents paint from accumulating on the top of the electromagnet 36.

[0045] Meanwhile, the content not detailedly described in this specification belongs to the well-known prior art of those skilled in the art.

[0046] During operation, when a device needs to be painted, the conveying device 2 is started. The conveying device 2 transports the device to the bottom of the limiting cylinder 33. The water pump inside the first heat preservation pipe 10 is started. The water pump inputs the paint inside the paint storage tank 6 into the heat preservation box 14 through the first heat preservation pipe 10. Under the action of gravity, the paint drives the sliding circular plate 17 to press down. The paint on the top of the sliding circular plate 17 gradually increases and continuously drives the sliding circular plate 17 to press down until the sliding circular plate 17 touches the first pressure sensor 16. The first pressure sensor 16 is pressured to control the first heat preservation pipe 10 to close and stop inputting paint into the heat preservation box 14, avoiding the paint inside the first heat preservation pipe 10 being too much and not being used up in time, resulting in the paint solidifying inside the heat preservation box 14. As time goes by, the paint inside the heat preservation box 14 gradually decreases. The limiting spring 15 drives the sliding circular plate 17 to gradually rise through elasticity until the sliding circular plate 17 rises to the side wall of the second pressure sensor 19. The second pressure sensor 19 is pressured to control the first heat preservation pipe 10 to start and continue to inject paint into the heat preservation box 14, completing the automatic feeding of the heat preservation box 14 and improving the automation degree of the device;

[0047] The water pump inside the heat preservation box 14 is started. The water pump sprays the paint inside the heat preservation box 14 onto the device to be sprayed through the second heat preservation pipe 20. When the second heat preservation pipe 20 sprays the paint, the third electric push rod 32 is started. The third electric push rod 32 extends. The third electric push rod 32 drives the limiting cylinder 33 to move to the side wall of the device to limit the paint, avoiding the paint spraying everywhere and affecting the already sprayed positions. When the third electric push rod 32 drives the limiting cylinder 33 to press down, the limiting cylinder 33 drives the blocking cylinder 37 to press down through the connecting rod 35 and the electromagnet 36 to protect the inner wall of the spraying pipe 34, avoiding the paint directly contacting the inner wall of the spraying pipe 34, resulting in the paint solidifying and adhering to the inner wall of the spraying pipe 34 and causing the spraying pipe 34 to be blocked, and prolonging the service life of the spraying pipe 34;

[0048] When the position of the spraying pipe 34 needs to be adjusted, start the second electric push rod 12. The second electric push rod 12 extends, and the second electric push rod 12 drives the second gear 13 to rise to the side walls of the first gear 7 and the third gear 21. Start the drive motor 3, and the drive motor 3 drives the transmission shaft 4 to rotate. The transmission shaft 4 drives the second heat preservation pipe 20 to rotate through the first gear 7, the second gear 13, the third gear 21, the fixed vertical rod 22 and the first limiting plate 23 to expand the working range of the spraying pipe 34. When the rotation of the second heat preservation pipe 20 is completed, start the second electric push rod 12, and the second electric push rod 12 drives the second gear 13 to contract and disengage from the side walls of the first gear 7 and the third gear 21 to prevent the drive motor 3 from driving the third gear 21 to rotate continuously. When the angle of the limiting cylinder 33 needs to be adjusted, the angle of the second heat preservation pipe 20 can be rotationally adjusted through the cooperation of the first limiting plate 23, the first electric rotating rod 26, the first control bin 24, the second control bin 25, the second electric rotating rod 27, the second limiting plate 28, the third electric rotating rod 29, the fourth electric rotating rod 30 and the third limiting plate 31;

[0049] When too much paint adheres to the inside of the barrier cylinder 37, the third gear 21 drives the second heat preservation pipe 20 to rotate to the top of the cleaning steel brush 9 through the fixed vertical rod 22 and the first limiting plate 23. Start the first electric push rod 8, and the first electric push rod 8 drives the cleaning steel brush 9 to extend into the inside of the barrier cylinder 37. The drive motor 3 drives the cleaning steel brush 9 to rotate through the transmission shaft 4 and the first electric push rod 8 to brush the inner wall of the barrier cylinder 37. When there is too much paint on the inner wall of the barrier cylinder 37 and it cannot be cleaned, turn off the electromagnet 36 to stop adsorbing and fixing the barrier cylinder 37, making it more convenient for the staff to replace the barrier cylinder 37. The setting of the barrier cylinder 37 prevents the paint from directly contacting the inside of the spraying pipe 34, resulting in the paint solidifying inside the spraying pipe 34 and causing blockage inside the spraying pipe 34, and preventing the cleaning steel brush 9 from directly brushing the inside of the spraying pipe 34, accelerating the wear of the spraying pipe 34. On the one hand, it is more convenient for the staff to replace the barrier cylinder 37, improving the work efficiency of replacement. On the other hand, it avoids excessive wear of the spraying pipe 34, which can reduce the cost of use and improve the work efficiency.
