Especially in the fields of unmanned driving and car navigation, navigation systems have long been maturely applied, and the importance of precise positioning of navigation systems has been revealed in many industries.

[0003] With the progress of social economy, science and technology and people's increasing demand for high-quality living standards, my country's construction and real estate industries have developed rapidly, requiring construction to develop from traditional inefficient manual construction to safe, efficient and high-quality construction methods. Spraying the interior walls of buildings is a link with a large workload in decoration construction. At present, the construction method is mainly manual spraying. This construction method has low production efficiency and high cost. There are often rework or even re-construction due to poor construction quality. The construction site environment is poor, and workers working in this environment for a long time are prone to occupational diseases. Therefore, using paint all-in-one machines for decoration operations has become a development trend in the construction industry.

[0004] In the prior art, during the operation of the paint machine, the paint sprayed at high speed from the spray gun is atomized to form fine paint particles that fill the working environment of the equipment. If a navigator with a general structure is applied to the paint machine to plan the working route of the paint machine, the paint particles during the operation of the paint machine will adhere to the window mask of the paint navigator, reducing the positioning accuracy of the paint navigator. As the paint continues to accumulate and overlap on the surface of the paint navigator mask, the navigator positioning will inevitably fail under long-term spraying operations.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a navigation device and a navigation method for a paint all-in-one machine.

[0023] Embodiment 1: See also Figure 1 - Figure 8 A navigation device of a paint integrated machine includes a navigation device installation plate 1, a paint navigation device 2 is installed on the outside of the navigation device installation plate 1, a lifting connection plate 3 is slidably installed inside the navigation device installation plate 1, a sliding shield 4 is connected to the outside of the lifting connection plate 3, a device support frame 5 is installed on the outside of the navigation device installation plate 1, a navigation device shield 6 is installed on the outside of the device support frame 5, an exhaust mechanism 7 is installed on the top of the navigation device installation plate 1, and a lifting mechanism 8 is installed inside the device support frame 5; The lifting mechanism 8 and the sliding shield 4 are respectively located on both sides of the navigation device mounting plate 1, the lifting mechanism 8 and the sliding shield 4 are connected via a lifting connection plate 3, and the outside of the lifting mechanism 8 is connected to the exhaust mechanism 7; The lifting mechanism 8 can drive the sliding shield 4 to move up and down through the lifting connecting plate 3. When the sliding shield 4 moves up and down, the state of the opening on the navigator protective cover 6 can be adjusted. The paint navigator 2 can obtain external environmental information through the opening on the navigator protective cover 6. The exhaust mechanism 7 can drive the air inside the navigator protective cover 6 to flow and discharge air through the opening on the navigator protective cover 6.

[0024] When the coating machine is working, the sliding shield 4 closes the opening on the navigator shield 6, and the interior of the exhaust mechanism 7 is also in a closed state, which can effectively prevent the atomized paint particles generated by spraying from entering the interior of the navigator shield 6 and adhering to the window of the coating navigator 2. When it is necessary to obtain external environmental information for navigation, the lifting mechanism 8 drives the lifting connecting plate 3 to move upward, and when the lifting connecting plate 3 moves upward, it can drive the sliding shield 4 to move upward. When the sliding shield 4 moves upward, the opening on the navigator shield 6 can be in an open state, and when the lifting mechanism 8 drives the lifting connecting plate 3 to move upward It can also drive the interior of the exhaust mechanism 7 to be in a connected state. After the interior of the exhaust mechanism 7 is connected, the exhaust mechanism 7 can drive air into the interior of the navigator protective cover 6, and drive the air entering the interior of the navigator protective cover 6 to be discharged from the opening on the navigator protective cover 6. The direction of air flow driven by the exhaust mechanism 7 is consistent with the direction of the window on the paint navigator 2, which can effectively prevent paint particles in the air from adhering to the window of the paint navigator 2 when obtaining external information at the window, thereby preventing atomized paint particles from adhering to the window mask of the paint navigator 2 during long-term work and affecting the navigation accuracy.

[0025] Embodiment 2: The difference from the above embodiment is that, please refer to Figure 1 - Figure 8 The navigator shield 6 includes a shield body 61, which is mounted inside the navigator mounting plate 1, a shield sealing block 62 is mounted inside the shield body 61, and a shield exhaust port 63 is opened inside the shield body 61; The height of the shield exhaust port 63 is consistent with the height of the window for obtaining environmental information on the paint navigator 2 , and the window on the paint navigator 2 can obtain external environmental information through the shield exhaust port 63 .

[0026] The sliding shield 4 can move up and down inside the shield body 61, and the outside of the sliding shield 4 fits with the shield sealing block 62 and the shield body 61. When the sliding shield 4 and the shield sealing block 62 fit together, the shield exhaust port 63 can be closed. When the sliding shield 4 is located at the upper portion of the shield body 61 , the shield air outlet 63 is in an open state, and when the sliding shield 4 is located at the lower portion of the shield body 61 , the shield air outlet 63 is in a closed state.

[0027] The lifting mechanism 8 includes an electric telescopic rod 81, which is installed inside the device support frame 5. The movable end of the electric telescopic rod 81 is connected to a lifting connecting rod 82. A partition lifting rod 83 is installed outside the lifting connecting rod 82. Both ends of the lifting connecting rod 82 are connected to a lifting connecting plate 3. The top of the partition lifting rod 83 is connected to the lower rotating shaft 78.

[0028] When the electric telescopic rod 81 is extended or shortened, it can drive the lifting connecting rod 82 to move up and down. When the lifting connecting rod 82 moves up and down, it can drive the lifting connecting plate 3 to move up and down. When the lifting connecting plate 3 moves up and down, it can drive the sliding shield 4 to move up and down. When the lifting connecting rod 82 moves up and down, it can drive the partition lifting rod 83 to move up and down. When the partition lifting rod 83 moves up and down, it can drive the lower rotating shaft 78 to move up and down inside the longitudinal sliding groove 75.

[0029] When the lifting connecting rod 82 is at the lowest point, the lifting connecting plate 3 and the lower rotating shaft 78 are both at the lowest point. When the lifting connecting plate 3 is at the lowest point, the sliding shield 4 can close the shield exhaust port 63. When the lower rotating shaft 78 is at the lowest point, the channel partition plate 76 can close the exhaust duct 73. When the lifting connecting rod 82 is at the highest point, the lifting connecting plate 3 and the lower rotating shaft 78 are both at the highest point, when the lifting connecting plate 3 is at the highest point, the shield exhaust port 63 is in an open state, and when the lower rotating shaft 78 is at the highest point, the exhaust duct 73 is in a connected state.

[0030] During the spraying operation, the exhaust duct 73 is separated by the partition plate 76 to prevent paint particles in the air from entering the interior of the shield body 61 from the exhaust duct 73, and the sliding shield 4 can also seal the shield exhaust port 63 by fitting with the shield body 61 and the shield sealing block 62, thereby preventing paint particles in the air from entering the interior of the shield body 61 from the shield exhaust port 63. When it is necessary to obtain external environmental information, the electric telescopic rod 81 is extended, and when the electric telescopic rod 81 is extended, it can drive the lifting connecting rod 82 to move upward. When the lifting connecting rod 82 moves upward, it can drive the sliding shield 4 to move upward through the lifting connecting plate 3. When the sliding shield 4 moves upward, the seal of the shield exhaust port 63 can be released, so that the paint navigator 2 can pass through The shield exhaust port 63 obtains external environmental information. After the information is obtained, the electric telescopic rod 81 contracts. When the electric telescopic rod 81 contracts, it can drive the lifting connecting plate 3 to move downward on the navigator mounting plate 1, and simultaneously drive the sliding shield 4 to move downward to continue to seal the shield exhaust port 63. The lifting mechanism 8 drives the sliding shield 4 to move up and down inside the shield body 61 to control whether the shield exhaust port 63 is sealed. When spraying, the sliding shield 4 seals the shield exhaust port 63, which can effectively prevent paint particles from entering the shield body 61 and attaching to the window of the paint navigator 2. When obtaining external information, the lifting mechanism 8 can drive the sliding shield 4 to move upward to release the seal of the shield exhaust port 63, so that the paint navigator 2 can obtain external information.

[0031] Embodiment three: The difference from the above embodiment is that, please refer to Figure 1 - Figure 8 The exhaust mechanism 7 includes an exhaust mounting seat 71 and a channel dividing plate 76. The exhaust mounting seat 71 is fixedly mounted on the top of the navigation instrument mounting plate 1. An exhaust fan 72 and an exhaust duct 73 are installed inside the exhaust mounting seat 71. The channel dividing plate 76 is installed inside the exhaust duct 73. Both sides of the exhaust duct 73 are provided with a horizontal slide groove 74 and a longitudinal slide groove 75. An upper rotating shaft 77 is installed on the upper part of the channel dividing plate 76, and a lower rotating shaft 78 is installed on the lower part of the channel dividing plate 76.

[0032] The exhaust fan 72 is connected to the outside of the navigation device protective cover 6 through the exhaust duct 73, and the channel partition plate 76 can separate the inside of the exhaust duct 73; The exhaust fan 72 can drive the air flow from the exhaust duct 73 into the interior of the navigation instrument protective cover 6 , and then discharge it from the interior of the navigation instrument protective cover 6 through the protective cover exhaust port 63 .

[0033] The transverse chute 74 is located above the longitudinal chute 75, the upper rotating shaft 77 outside the channel partition plate 76 is slidably installed inside the transverse chute 74, and the lower rotating shaft 78 outside the channel partition plate 76 is slidably installed inside the longitudinal chute 75; When the lifting mechanism 8 drives the lower rotating shaft 78 to move upward along the longitudinal slide groove 75, it can drive the upper rotating shaft 77 to move along the transverse slide groove 74 in the direction away from the longitudinal slide groove 75. When the lower rotating shaft 78 moves upward, it can drive the channel partition plate 76 to rotate from a vertical state to a horizontal state inside the exhaust duct 73. When the channel partition plate 76 is in a vertical state, the channel partition plate 76 separates the exhaust duct 73. When the channel partition plate 76 is in a horizontal state, the interior of the navigation instrument protective cover 6 is connected to the outside through the exhaust duct 73.

[0034] When the spraying operation is in progress, the channel partition plate 76 is in a vertical state. At this time, the channel partition plate 76 separates the interior of the exhaust duct 73, which can prevent paint particles in the air from entering the interior of the shield body 61 through the exhaust duct 73. When it is necessary to obtain external environmental information, the electric telescopic rod 81 extends to drive the lifting connecting rod 82 to move upward. When the lifting connecting rod 82 moves upward, it can drive the sliding shield 4 to move upward to release the blockage of the shield exhaust port 63. When the lifting connecting rod 82 moves upward, it can also drive the lower rotating shaft 78 to move upward along the longitudinal slide groove 75 through the separation lifting rod 83. When the lower rotating shaft 78 moves upward along the longitudinal slide groove 75, it can drive the upper rotating shaft 77 to move along the transverse slide groove 74 in the direction away from the longitudinal slide groove 75. At this time, it can drive the channel partition plate 76 to rotate from a vertical state to a horizontal state inside the exhaust duct 73. During the rotation process of the channel partition plate 76, the separation of the interior of the exhaust duct 73 can be released. At this time, the interior of the protective cover body 61 can be connected to the outside through the exhaust duct 73, and then the exhaust fan 72 is started, and the external air is driven into the interior of the protective cover body 61 by the exhaust fan 72, and the air inside the protective cover body 61 flows out from the protective cover exhaust port 63. At this time, the paint navigator 2 can obtain external environmental information through the protective cover exhaust port 63. When the paint navigator 2 obtains external environmental information, the exhaust fan 72 drives the air flow to be discharged outward along the protective cover exhaust port 63. When the air flow inside the protective cover body 61 flows outward along the protective cover exhaust port 63, it can prevent paint particles in the external air from entering the protective cover body 61 and attaching to the window of the paint navigator 2. Since the direction of the air flow inside the protective cover body 61 is consistent with the direction in which the paint navigator 2 obtains environmental information, the paint particles in the air will not attach to the window of the paint navigator 2 when the air flows, thereby ensuring that the paint navigator 2 can maintain accuracy even when working for a long time.

[0035] Embodiment 4: A navigation method, using a navigation device of a coating machine as in the first to third embodiments, comprises the following steps: During the spraying operation, the exhaust mechanism 7 and the sliding shield 4 can prevent paint particles from entering the interior of the navigator shield 6 and adhering to the window of the paint navigator 2; When it is necessary to obtain external environmental information, the lifting mechanism 8 drives the sliding shield 4 to move upward; When the lifting mechanism 8 drives the sliding shield 4 to move upward, the interior of the exhaust mechanism 7 can also be connected; After the exhaust mechanism 7 is internally connected, the exhaust mechanism 7 can drive the external airflow into the interior of the navigator protective cover 6 and be discharged from the opening on the navigator protective cover 6; After the environmental information is acquired, the lifting mechanism 8 drives the sliding shield 4 and the exhaust mechanism 7 to continue to seal the interior of the navigator shield 6 .
