[0010] Furthermore, the present invention provides a dust collection device suitable for robot operation, wherein two exhaust holes are respectively provided on the four side walls of the second housing, the internal thread interface of the second housing is offset to one side, and the suction cylinder is located on the opposite side of the offset direction of the internal thread interface.

[0011] Furthermore, the present invention provides a dust collection device suitable for robot operation, wherein the sampling bottle is a standard centrifuge bottle made of transparent material and is equipped with a cap.

[0012] Based on the same concept, the present invention also provides a method of using the above-mentioned dust collection device, comprising the following steps:

[0013] S1. Place the dust collection device on the robot's bracket and drive the robot to the sampling area;

[0014] S2. Use the robot's robotic arm to hold the two adapters and pull the dust collection device out of the bracket, and press the button with the robotic arm to connect the power supply line between the battery pack and the motor.

[0015] S3. After the dust collection device is moved to the ground where the suction cylinder is located by the robotic arm, the dust collection device is moved from top to bottom until the lower end of the suction cylinder contacts the ground.

[0016] S4. When the amount of dust collected in the sampling bottle meets the requirements, the dust collection device is placed back on the bracket by the robotic arm, and the clamp on the adapter and the button are released.

[0018] Furthermore, in a method of using the dust collection device described above, in step S5, moving the dust collection device to the designated area by a robotic arm means using the robotic arm to hold two adapters, pulling the dust collection device from the bracket, and then releasing the grip on the adapters after moving the dust collection device to the designated area.

[0019] Compared with existing technologies, the dust collection device and its usage method suitable for robot operation of the present invention have the following advantages: The robot is equipped with a bracket and a robotic arm. The present invention configures the dust collection device with a suction power module, a dust collection module, and a sampling bottle. The suction power module is equipped with a support plate and a first housing fixed to the upper side of the support plate. A battery pack and a motor are fixed to the support plate in the first housing. The output shaft of the motor passes downward through the support plate and is fitted with a suction fan. A button matching the robotic arm and two symmetrically distributed adapters are fixed to the outside of the first housing. The button is used to control the power supply line between the battery pack and the motor. The dust collection module is configured with a second housing and a filter element installed within it. The second housing is fixed to the underside of a support plate, with the suction fan positioned within its cavity. The filter element is located below the suction fan. An exhaust vent is located on the side wall of the second housing above the filter element. The second housing below the filter element adopts a funnel-shaped structure and is fitted to a bracket. An internal threaded interface is provided at the bottom of the second housing. A vertical suction cylinder, communicating with the inner cavity of the second housing, is located on one side of the internal threaded interface, with the connection between the suction cylinder and the second housing positioned below the filter element. A sampling bottle is then threaded onto the internal threaded interface of the second housing. This constitutes a simple, easy-to-operate, and highly practical dust collection device suitable for robot operation. When dust sampling is required, first place the dust collection device on the robot's bracket and move the robot to the sampling area. Then, use the robot's robotic arm to hold the two adapters and pull the dust collection device from the bracket. Press the button on the robotic arm to connect the power line between the battery pack and the motor, at which point the suction fan starts working. Next, use the robotic arm to move the dust collection device to the ground where the suction cylinder is located, and move the dust collection device from top to bottom until the lower end of the suction cylinder touches the ground. At this point, the dust will be continuously sucked into the second shell along with the air. The air drawn in by the device is exhausted through the exhaust vent, while the inhaled dust, blocked by the filter, falls into the sampling bottle through the lower half of the second housing. When the amount of dust collected in the sampling bottle meets the requirements, the robotic arm places the dust collection device back onto the bracket, releases the clamp on the adapter and the button, disconnecting the power supply between the battery pack and the motor, and stopping the suction fan. The robot then returns to the designated position, and the robotic arm moves the dust collection device to the designated area. Finally, the sampling bottle is manually unscrewed from the second housing, the cap is screwed on, and the sample is sent for testing. This completes one dust sampling and testing process. Compared with existing manual sampling equipment and manual dust collection methods, using the dust collection device provided by this invention in conjunction with a robot to collect dust in contaminated or flammable / explosive environments avoids the risk of personnel infection and safety hazards while improving sampling efficiency. The dust collection device and method provided by this invention have the advantages of simple process, safety and reliability, and high work efficiency.

[0028] First, it should be noted that the directional terms such as up, down, left, right, front, and back used in this invention are merely descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this invention.

[0029] like Figures 1 to 7The present invention illustrates a specific embodiment of a dust collection device suitable for robot operation. The robot is equipped with a bracket and a robotic arm. The dust collection device includes a suction power module 1, a dust collection module 2, and a sampling bottle 3. The suction power module 1 is equipped with a support plate 11 and a first housing 12 fixed to the upper side of the support plate 11. A battery pack 13 and a motor 14, both fixed to the support plate 11, are disposed in the first housing 12. The output shaft of the motor 14 passes downward through the support plate 11 and is fitted with a suction fan 15. A button 16 matching the robotic arm and two symmetrically distributed adapters 17 are fixed to the outside of the first housing 12. The button 16 is used to control the on / off state of the power supply line between the battery pack 13 and the motor 14. The dust collection module 2 is equipped with a second housing 21 and a filter 22 installed in the second housing 21. The second housing 21 is fixed to the lower side of the support plate 11 and the dust suction fan 15 is placed in its inner cavity. The filter 22 is placed below the dust suction fan 15. An exhaust hole 211 is provided on the side wall of the second housing 21 above the filter 22. The second housing 21 below the filter 22 adopts a funnel-shaped structure and is matched with the bracket. An internal thread interface is provided at the bottom of the second housing 21. A vertical suction cylinder 23 communicating with the inner cavity of the second housing 21 is provided on one side of the internal thread interface. The connection between the suction cylinder 23 and the second housing 21 is located below the filter 22. The sampling bottle 3 is installed on the internal thread interface of the second housing 21 by threads.

[0030] The above setup constitutes a simple, easy-to-operate, and highly practical dust collection device suitable for robot operation. When dust sampling is required, first place the dust collection device on the robot's bracket and move the robot to the sampling area. Then, use the robot's robotic arm to grip the two adapters 17 and pull the dust collection device from the bracket. Press button 16 with the robotic arm to connect the power supply line between the battery pack 13 and the motor 14, at which point the motor 14 and the suction fan 15 begin to operate. Next, use the robotic arm to move the dust collection device to the suction cylinder 23, aligning it with the ground where the target dust is located. Move the dust collection device from top to bottom until the lower end of the suction cylinder 23 contacts the ground. At this point, the dust will be continuously sucked into the second housing 21 along with the air. The inhaled air is discharged through the exhaust port 211, and the inhaled dust, after being blocked by the filter 22, falls into the sampling bottle 3 through the lower half of the inner cavity of the second housing 21. When the amount of dust collected in the sampling bottle 3 meets the requirements, the robotic arm places the dust collection device back onto the bracket, releases the clamp on the adapter 17 and the press of the button 16, at which point the power supply line between the battery pack 13 and the motor 14 is disconnected, and the motor 14 and the vacuum fan 15 stop working. Then the robot returns to the designated position, and the robotic arm moves the dust collection device to the designated area. Finally, the sampling bottle 3 is manually unscrewed from the second housing 21, the cap is screwed on, and the sample is sent for testing. This completes one dust sampling and testing process. Compared with existing manual sampling equipment and manual dust collection methods, using the dust collection device provided by this invention in conjunction with a robot to conduct dust sampling in contaminated or flammable and explosive environments avoids the risk of personnel infection and safety hazards, while also improving sampling efficiency. This invention improves the stability and reliability of the robotic arm's gripping by setting up a first housing 12 and an adapter 17. By adopting a funnel-shaped structure for the lower half of the second housing 21, the dust collection device can be accurately and quickly inserted into the matching bracket, ensuring the stability of the dust collection device. Furthermore, it facilitates the collection of dust and structural arrangement, making it easier to set up the suction cylinder 23. It should be noted that in practical applications, this invention uses a standard centrifuge bottle made of transparent material with a cap for the sampling bottle 3, allowing for direct delivery of samples for subsequent testing after collection. This reduces the cumbersome sample transfer process, lowers the risk of contamination during sample transfer, and improves sample collection efficiency and safety. Additionally, it should be pointed out that the robot described in this paper is a self-propelled robot. Both the robot's movement and the robotic arm's actions can be remotely controlled. The robot is also equipped with a camera to observe the sampling site via a visual remote control panel. However, it should be noted that the robot, robotic arm, and camera are all existing technologies in the field, and their structures, principles, and connections are well known to those skilled in the art. The bracket is designed to facilitate the placement of the dust collection device. The bracket has a funnel-shaped slot that matches the lower half of the second housing 21 to facilitate positioning and holding the dust collection device.

[0031] As an optimized solution, in this specific embodiment, an indicator light 18 is fixed on the first housing 12 and connected to the power supply line between the control battery pack 13 and the motor 14. This way, the indicator light 18 will illuminate when the power supply line is connected, allowing the operator to easily determine the status of the dust collection device. To facilitate the removal and installation of the filter element 22, this specific embodiment provides a limiting ring platform 212 on the inner wall of the second housing 21. The filter element 22 is placed on the limiting ring platform 212, and a retaining ring 24 is threadedly installed in the inner cavity of the second housing 21 above the filter element 22. The filter element 22 can then be removed for easy replacement by removing the retaining ring 24. During installation, the filter element 22 is placed on the limiting ring platform 212, and the retaining ring 24 is screwed on to press the filter element 22 against the limiting ring platform 212.

[0032] In a specific embodiment, for ease of assembly and disassembly, the first housing 12 and the second housing 21 are respectively fixed to the upper and lower sides of the support plate 11 with bolts, and the two adapters 17 are respectively fixed to the two sides of the first housing 12 with bolts. For ease of installation and positioning, the present invention provides a boss 111 on the support plate 11 for positioning the first housing 12, and fixes the battery pack 13 and the motor 14 to the support plate 11 via brackets 131 and motor mounts 141. In practical applications, the present invention uses a square plate for the support plate 11, a square structure for the first housing 12, and a square structure for the second housing 21 on the upper side of the filter element 22, to simplify the structure and manufacturing process. The second housing 21 on the lower side of the filter element 22 is a funnel-shaped structure in the shape of a frustum of a square pyramid to facilitate accurate positioning with the bracket. To improve ventilation efficiency, the present invention provides two ventilation holes 211 on each of the four side walls of the second housing 21; and offsets the internal thread interface of the second housing 21 to one side, and sets the suction cylinder 23 on the opposite side of the offset direction of the internal thread interface to facilitate structural arrangement.

[0033] Based on the same concept, the present invention also provides a method of using the above-mentioned dust collection device, comprising the following steps:

[0034] S1. Place the dust collection device on the robot's bracket and drive the robot to the sampling area.

[0035] S2. Using the robot's robotic arm to grip the two adapters 17, the dust collection device is pulled out of the bracket, and the power supply line between the battery pack 13 and the motor 14 is connected by pressing the button 16 with the robotic arm. The motor 14 and the vacuum fan 15 then start working.

[0036] S3. The dust collection device is moved by the robotic arm to the ground where the suction cylinder 23 is located, and then the dust collection device is moved from top to bottom until the lower end of the suction cylinder 23 contacts the ground. Dust is continuously sucked into the second housing 21 along with the air. The sucked-in air is discharged through the exhaust port 211, and the sucked-in dust is blocked by the filter 22 and falls into the sampling bottle 3 through the lower half of the inner cavity of the second housing 21.

[0037] S4. When the amount of dust collected in sampling bottle 3 meets the requirements, the dust collection device is placed back on the bracket by the robotic arm, and the clamp on adapter 17 and the button 16 are released. The power supply line between battery pack 13 and motor 14 is disconnected, and motor 14 and vacuum fan 15 stop working.

[0038] S5. Return the robot to the designated position and move the dust collection device to the designated area using the robotic arm; manually unscrew the sampling bottle 3 from the second housing 21, screw on the cap, and send it for testing.

[0039] In step S5, moving the dust collection device to the designated area using a robotic arm means using the robotic arm to grip the two adapters 17, pulling the dust collection device from the bracket, moving the dust collection device to the designated area, and then releasing the grip on the adapters 17. This completes one dust sampling and testing process.
