Description

Technical Field

[0001] The present application relates to the technical field of AGV (Automatic Guided Vehicle), and in particular to a dust removal device. Background Art

[0002] AGVs are battery-powered, driverless automated transport vehicles with independent addressing systems. They are widely used in industrial and commercial environments to automatically transport items within warehouses, factories, hospitals, and other locations. AGVs are often equipped with laser sensors that sense and navigate the environment, enabling them to follow specific paths or navigate autonomously based on real-time sensor data.

[0003] However, AGVs used in dusty workplaces such as warehouses and factories will suffer from dust accumulation on the surface of laser sensors, causing the laser sensors to misjudge that they have encountered obstacles, causing the AGV to stop and remain in place, thereby interfering with the normal operation of other AGVs and reducing the working efficiency of the AGV.

[0004] In the prior art, when an AGV mistakenly judges that it has encountered an obstacle, human intervention is required, which increases the personnel's extra work content and reduces the personnel's production efficiency. In addition, in the prior art, manual wiping of the dust on the surface of the laser sensor is usually adopted to enable the AGV to resolve the misjudgment. However, the above operation method may cause uneven manual wiping force, which may cause wear on the laser surface of the laser sensor, thereby affecting the accurate judgment of the laser sensor, which is not conducive to the subsequent stable operation of the AGV, and thus reduces the working efficiency of the AGV. In addition, when personnel wipe the laser sensor with excessive force, it may also cause the laser to debond, thereby causing damage to the laser sensor and further reducing the working efficiency of the AGV.

[0005] Therefore, how to avoid misjudgment caused by dust attached to the AGV and manual dust cleaning that reduces the working efficiency of the AGV is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0026] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 Front, back, left, right, up and down as shown.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides a dust removal device 100, which is used to remove dust from AGV200. The dust removal device 100 includes a shell 11, a device door 12 and a nozzle assembly 13. Specifically, a dust removal space 111 for accommodating AGV200 is formed in the shell 11, and an opening 112 is provided on one side of the shell 11. The device door 12 is configured to cover the opening 112 or to be separated from the opening 112. The nozzle assembly 13 is located in the dust removal space 111 and is connected to the shell 11. The nozzle assembly 13 is configured to be able to transport dust removal gas into the dust removal space 111. In the present application, a laser sensor (not shown) is provided at the front end of the AGV200 along the front and rear directions of the dust removal device 100. The laser sensor is used to sense and navigate the environment so that the AGV200 can navigate autonomously. Through the above setting, AGV200 enters the dust removal space 111, and then transports dust removal gas through the nozzle assembly 13, so that the dust removal gas can remove dust from AGV200, and then blow away the dust attached to the laser sensor, so as to achieve the purpose of automatic dust removal of the laser sensor.

[0028] Through the above settings, it is possible to avoid the situation where the AGV200 misjudges that it has encountered an obstacle and stops running due to dust adhering to the laser sensor, so that the AGV200 can continue to operate stably, which is beneficial to improving the working efficiency of the AGV200. In addition, there is no need for additional work caused by manual handling of the stopped AGV200, which is beneficial to improving the work efficiency of personnel. Secondly, by automatically blowing and dusting the laser sensor, it is possible to avoid the situation where the laser sensor is worn or even damaged due to uneven force when manually wiping the laser sensor, which is beneficial to increasing the service life of the laser sensor, and then it is beneficial to improve the operating stability of the AGV200, and further improve the working efficiency of the AGV200.

[0029] Furthermore, the closure of the housing 11 and the device door 12 forms a dust removal space 111 that is isolated from the outside world, thereby preventing external dust from spreading into the dust removal space 111, thereby facilitating the cleanliness of the dust removal space 111 and, in turn, facilitating the cleaning of the AGV 200. Furthermore, dust raised during the dust removal process of the AGV 200 in the dust removal space 111 is prevented from spreading to the outside world, thereby facilitating the cleanliness of the external environment.

[0030] As an embodiment, the dust removal device 100 further includes a sensing component (not shown), which is located in the dust removal space 111 and connected to the housing 11. The sensing component is configured to detect whether the AGV 200 is located in the dust removal space 111. In this configuration, the position of the AGV 200 is detected by the sensing component, which facilitates controlling the opening and closing of the device door 12 and controlling the nozzle assembly 13 to deliver gas.

[0031] For example, when the sensing component detects that AGV 200 has entered dust removal space 111, the device door 12 is controlled to close, thereby forming a substantially sealed space in dust removal space 111. The nozzle assembly 13 is then activated to deliver dust removal gas to remove dust from AGV 200. After dust removal is complete, the device door 12 opens, and AGV 200 exits dust removal space 111. When the sensing component detects that AGV 200 is no longer in dust removal space 111, the device door 12 is controlled to close, preventing external dust from entering dust removal space 111, thereby maintaining the cleanliness of dust removal space 111.

[0032] In some embodiments, the sensing component may be an infrared sensor, which can detect whether the AGV 200 is located in the dust removal space 111 .

[0033] In this embodiment, the sensing component is detachably connected to the dust removal space 111. This arrangement facilitates adjustment of the position of the sensing component within the dust removal space 111, thereby enabling flexible installation of the sensing component according to the size of the AGV 200 and improving the accuracy of the sensing component in detecting the position of the AGV 200.

[0034] As an embodiment, the nozzle assembly 13 includes at least one first nozzle 131, and the first nozzle 131 is located on the side of the housing 11 away from the outlet 112. In the present application, along the front-to-back direction of the dust removal equipment 100, the laser sensor is located at the front end of the AGV 200, and the equipment door 12 is located at the rear end of the housing 11. Moreover, when the AGV 200 enters the dust removal space 111, the laser sensor is located at the end away from the outlet 112. Through the above arrangement, the first nozzle 131 can be set toward the laser sensor, so that the dust removal gas delivered by the first nozzle 131 can accurately blow away the dust attached to the laser sensor, thereby helping to improve the dust removal efficiency of the dust removal equipment 100 for laser sensing.

[0035] Specifically, a plurality of first nozzles 131 are provided, and the plurality of first nozzles 131 are at least partially distributed along the vertical direction. In the present application, the vertical direction is the up-down direction of the dust removal equipment 100. Such an arrangement enables the first nozzle 131 to comprehensively purge the AGV 200 in the up-down direction, so as to improve the comprehensiveness of the dust removal equipment 100 in cleaning the AGV 200 as a whole. Moreover, when installed on AGVs 200 of different sizes, resulting in the laser sensors being located at different heights, the plurality of first nozzles 131 can purge the laser sensors at different heights, so that the first nozzle 131 can clean the laser sensors installed at any height on the AGV 200 along the up-down direction of the dust removal equipment 100, thereby improving the comprehensiveness of the cleaning of the dust removal equipment 100.

[0036] More specifically, the plurality of first nozzles 131 are at least partially distributed in a horizontal direction. In this application, the horizontal direction is perpendicular to the vertical direction of the dust removal device 100. This arrangement can further improve the comprehensiveness of the cleaning of the AGV 200 by the first nozzles 131.

[0037] As an optional implementation, the nozzle assembly 13 includes multiple second nozzles 132, located on either side of the housing 11 where the opening 112 meets. In this application, the second nozzles 132 are located on either side of the housing 11, along the left and right sides of the dust removal device 100. This arrangement allows the second nozzles 132 to purge both the left and right sides of the AGV 200, further improving the comprehensiveness of the dust removal device 100's cleaning of the AGV 200.

[0038] Specifically, the plurality of second nozzles 132 are at least partially distributed vertically. This arrangement enables the second nozzles 132 to comprehensively purge the left and right sides of the AGV 200 along the vertical direction of the dust removal equipment 100, thereby ensuring a more thorough purge of the AGV 200 by the dust removal equipment 100. Furthermore, this arrangement allows the second nozzles 132 to purge AGVs 200 at different heights, thereby improving the comprehensiveness of the dust removal by the second nozzles 132.

[0039] More specifically, the plurality of second nozzles 132 are at least partially distributed in the horizontal direction. This arrangement can further improve the comprehensiveness of the second nozzles 132 in blowing the left and right sides of the AGV 200.

[0040] like Figure 2 and Figure 4 As shown, as an embodiment, the housing 11 includes two first columns 113, multiple second columns 114, multiple cross columns 115, and a cover 116. The first columns 113 and the second columns 114 extend vertically, the cross columns 115 extend horizontally, the two first columns 113 are adjacent to each other, and an opening 112 is formed between the two first columns 113. Multiple cross columns 115 are connected between adjacent second columns 114 and between the second columns 114 and the first columns 113. The cover 116 covers the second columns 114 and the cross columns 115. The device door 12 covers the opening 112 between the two first columns 113, forming a dust removal space 111. In this embodiment, the cover 116 is at least partially located at the upper end of the dust removal device 100 along the vertical direction of the dust removal device 100; at least partially located at the left and right ends of the dust removal device 100 along the left and right directions of the dust removal device 100; and at least partially located at the front end of the dust removal device 100 along the front and back directions of the dust removal device 100. This arrangement enables the cover 116 to cooperate with the device door 12 to form a substantially sealed dust removal space 111, thereby preventing external dust from entering the dust removal space 111, thereby maintaining the cleanliness of the dust removal space 111 and improving the dust removal efficiency of the dust removal device 100 for the AGV 200.

[0041] In some embodiments, there are two second columns 114. When viewed from above and below the dust removal device 100, the two first columns 113 and the two second columns 114 are located at the four corners of a square, giving the dust removal device 100 a cubic structure. This arrangement simplifies the cubic structure, thereby simplifying the assembly process of the first columns 113, the second columns 114, and the horizontal column 115.

[0042] It should be noted that the present application does not impose any restrictions on the structural shape of the dust removal equipment 100 , and it only needs to ensure that the dust removal equipment 100 can accommodate the AGV 200 for blowing.

[0043] As an embodiment, multiple horizontal columns 115 are distributed in the vertical direction between two adjacent second columns 114 and between the second column 114 and the first column 113. Specifically, a plurality of first nozzles 131 are provided, and the plurality of first nozzles 131 are respectively located on the multiple horizontal columns 115 between two adjacent second columns 114. In this embodiment, along the front-to-back direction of the dust removal device 100, the horizontal columns 115 between two adjacent second columns 114 are located at the front end of the dust removal device 100, so that the first nozzle 131 can be arranged at the front end of the dust removal device 100, thereby facilitating the first nozzle 131 to purge the laser sensor provided at the front end of the AGV 200.

[0044] More specifically, the plurality of second nozzles 132 are respectively located on the plurality of transverse columns 115 between the second upright columns 114 and the first upright columns 113. In this embodiment, along the left-right direction of the dust removal device 100, the transverse columns 115 between two adjacent second upright columns 114 are located at the left and right ends of the dust removal device 100, so that the second nozzles 132 can be arranged at the left and right ends of the dust removal device 100, thereby facilitating the second nozzles 132 to purge the left and right ends of the AGV 200, thereby facilitating more comprehensive cleaning of the AGV 200 by the dust removal device 100.

[0045] In the present application, multiple groups of sensing components can be provided, and the multiple groups of sensing components are evenly arranged in the dust removal space 111 along the up and down directions of the dust removal equipment 100, so that the sensing components can sense the height of the AGV200 entering the dust removal space 111, so as to facilitate controlling the start-up and delivery of the dust removal gas by the first nozzle 131 and the second nozzle 132.

[0046] For example, the sensing component can sense the height of the AGV 200 entering the dust removal space 111 and control the first nozzle 131 and the second nozzle 132 within the height range corresponding to the AGV 200 to start and deliver dust removal gas. The first nozzle 131 and the second nozzle 132 above the corresponding height of the AGV 200 are shut down, thereby avoiding gas waste caused by the first nozzle 131 and the second nozzle 132 delivering gas above the height of the AGV 200, thereby saving dust removal gas and further reducing the operating cost of the dust removal equipment 100.

[0047] like Figure 4 As shown, as an embodiment, the dust removal device 100 further includes an air supply pipe 14, which is configured to deliver dust removal gas to the first nozzle 131 and the second nozzle 132. In this configuration, the first nozzle 131 and the second nozzle 132 can be connected to an external air supply device through the air supply pipe 14 to achieve the function of delivering dust removal gas.

[0048] As an embodiment, the dust removal device 100 further includes a drive assembly 15, which is connected to the device door body 12 and is configured to drive the device door body 12 to cover the opening 112 or separate from the opening 112. In some embodiments, the drive assembly 15 is a motor, and the device door body 12 is a rolling shutter. The motor drives the rolling shutter to retract, thereby opening the dust removal device 100, which facilitates the AGV 200 to enter and exit the dust removal space 111; the motor drives the rolling shutter to unfold, thereby closing the dust removal device 100, thereby making the dust removal space 111 a substantially sealed space, which facilitates isolating the dust removal space 111 from the external environment.

[0049] It should be noted that the drive assembly 15 can also be a hydraulic cylinder, and the device door 12 can be a plate-like structure. The hydraulic cylinder can drive the device door 12 to move up and down to achieve the opening and closing of the device door 12. Therefore, this application does not impose any restrictions on the structure of the drive assembly 15 and the device door 12, as long as they can achieve the opening and closing of the opening 112.

[0050] like Figure 4 As shown, as an embodiment, the dust removal device 100 also includes an air purification component 16 mounted on the housing 11. The air purification component 16 is at least partially connected to the dust removal space 111, and the air purification component 16 is configured to be able to remove dust from the dust removal space 111. In this way, after the dust removal device 100 removes dust from the AGV 200, the air purification component 16 can be used to clean the dust swept down by the dust removal gas to maintain the cleanliness of the dust removal space 111. In addition, the air purification component 16 can also be turned on during the dust removal process of the AGV 200 by the dust removal device 100 to prevent the dust blown down during the dust removal process from spreading in the dust removal space 111 and causing secondary contamination of the laser sensor, thereby facilitating the improvement of the cleaning effect of the dust removal device 100. In some embodiments, the air purification component 16 is an air purifier, which can clean the dust in the dust removal space 111 through an air purifier to facilitate maintaining the cleanliness of the dust removal space 111, thereby facilitating the cleaning of the AGV 200.

[0051] In this application, the dust removal steps of the dust removal device 100 on the AGV 200 are as follows:

[0052] First, the dust removal equipment 100 is fixed in the work site, and the position of the dust removal equipment 100 is entered and interacted in the navigation map of the AGV, so that the AGV200 can regularly drive into the dust removal equipment 100 for dust removal.

[0053] When AGV200 drives to the dust removal equipment 100, the driving component 15 drives the equipment door 12 to open, and AGV200 drives into the dust removal space 111. After the sensing component senses that AGV200 is located in the dust removal space 111, the driving component 15 drives the equipment door 12 to close, so that the dust removal space 111 forms a basically sealed space.

[0054] Then, the dust removal gas is delivered into the dust removal space 111 through the nozzle assembly 13, thereby purging the AGV 200 in the dust removal space 111 and further cleaning the dust attached to the laser sensor. At this time, the air purification assembly 16 can clean the dust diffused in the dust removal space 111, thereby preventing the dust swept away by the dust removal gas from attaching to the laser sensor again, thereby improving the cleaning effect of the dust removal device 100 on the laser sensor.

[0055] After the purge is completed, the driving component 15 drives the equipment door 12 to open, and the AGV 200 drives out of the dust removal space 111. The air purification component 16 can clean the dust remaining in the dust removal space 111.

[0056] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
