Description

Technical Field

[0001] The utility model relates to the technical field of robot accessories, in particular to a cleaning device for an AGV robot. Background Art

[0002] An AGV robot is a transport device equipped with an automatic navigation system, such as an electromagnetic or optical one, capable of traveling along a prescribed navigation path and featuring safety protection and various transfer functions. Currently, AGVs are primarily used for material handling in factory production, where they can efficiently, accurately, and flexibly complete material handling tasks. As a fundamental transport tool, AGVs are widely used in a variety of industries, including production and processing, appliance production, electronics manufacturing, intelligent warehousing, and express logistics. Production and processing and express logistics are currently the most widely used areas for AGVs.

[0003] Existing AGVs are primarily fixed-height wheeled structures, offering flexible mobility and easy control. However, these robots have limited adaptability and poor obstacle-crossing capabilities. When used in specialized scenarios, AGVs often encounter complex road surfaces with numerous obstacles and debris. Manual pre-clearance is labor-intensive and impacts the robot's operating efficiency. Oversight can also lead to the AGV hitting obstacles and causing accidents, necessitating a cleaning device. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention discloses a cleaning device for an AGV robot. The technical solution adopted is that a cleaning base is installed at the bottom of the robot, and two mounting brackets are fixedly installed on both sides of the front of the cleaning base. The mounting brackets are fixedly connected to the top of the cleaning base by bolts, which is convenient for disassembly and maintenance. The mounting brackets are fixedly connected to a guide slide bar through a support block, and a spring and a slider are slidably connected on the guide slide bar. The upper end of the spring presses on the support block, and the lower end presses on the slider. The two sliders are fixedly connected to a baffle fixing bracket, and a cleaning baffle is fixedly connected to the front of the lower part of the baffle fixing bracket. The elastic force of the spring is used to keep the cleaning baffle at the lowest end of the guide slide bar, so that it can maintain contact with the ground, push and clean obstacles and debris on the ground, and ensure the safety of the robot's movement. An adjustment rod is mounted on the front side of the baffle holder, sliding through a latch slot on the front side of the cleaning base. The latch slot is in an inverted L-shape. When the road surface is in good condition and no cleaning is required, the baffle holder and cleaning baffle can be manually raised upward using the adjustment rod. After the adjustment rod slides to the upper end along the latch slot, it slides horizontally and snaps into the latch slot. The adjustment rod then lifts the baffle holder and cleaning baffle and restrains them in the cleaning base, allowing the robot to move quickly. A travel switch is fixed to the rear of the cleaning baffle, on the side of the slider. This travel switch is electrically connected to the robot's control center. The travel switch can detect the deformation of the cleaning baffle during operation. If the cleaning baffle is compressed and deformed excessively due to a large obstacle, the travel switch will be triggered, which will then send a signal back to the robot, prompting the operator to intervene manually.

[0005] As a preferred solution of the present invention, an ultrasonic sensor is installed in the middle of the front side of the cleaning base, and the ultrasonic sensor is electrically connected to the control center of the robot to serve as a motion detection device of the robot.

[0006] The beneficial effects of the present invention are as follows: the present invention installs a cleaning baffle on the cleaning base through a mounting frame, and utilizes a combination of a spring and a slider to enable the cleaning baffle to slide up and down on the guide slide bar. Under the action of the spring, the cleaning baffle always remains at the bottom end, can contact the ground, and push and clean obstacles on the ground to ensure the normal operation of the robot. The travel switch can be used to detect the deformation of the cleaning baffle during operation. If a large obstacle is encountered and the cleaning baffle is compressed and deformed too much, the travel switch will be triggered, and the travel switch will feed back a signal to the robot to remind the staff to intervene manually. When cleaning is not needed, the cleaning baffle can also be manually lifted up and retracted into the cleaning base through the adjustment rod so that the robot can move quickly. The entire device has a simple structure, is easy to control, can effectively clean obstacles on the road, is safe, reliable, and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Example 1

[0013] like Figures 1 to 4 As shown, the present invention is a cleaning device for an AGV robot. The cleaning base 1 is mounted on the bottom of the robot 11. An ultrasonic sensor 10 is mounted in the middle of the front side of the cleaning base 1. The ultrasonic sensor 10 is electrically connected to the control center of the robot 11 and serves as a motion detection device for the robot 11. Two mounting brackets 2 are fixedly mounted on both sides of the front of the cleaning base 1. The mounting brackets 2 are bolted to the top of the cleaning base 1 for easy disassembly and maintenance. The mounting brackets 2 are fixedly connected to the guide slide 3 via a support block 301. The guide slide 3 is slidably connected to a spring 4 and a slider 5. The upper end of the spring 4 presses against the support block 301 and the lower end presses against the slider 5. The two sliders 5 are fixedly connected to a baffle fixing bracket 6. A cleaning baffle 8 is fixedly connected to the front of the baffle fixing bracket 6. The elastic force of the spring 4 keeps the cleaning baffle 8 at the lowest end of the guide slide 3, thereby maintaining contact with the ground, pushing and clearing obstacles and debris on the ground, and ensuring the safety of the robot's movement.

[0014] The front side of the baffle fixing frame 6 is equipped with an adjustment rod 7 for sliding and snapping. The adjustment rod 7 can slide horizontally on the baffle fixing frame 6. The adjustment rod 7 extends from a snap slot 101 provided on the front side of the cleaning base 1. The snap slot 101 is in an inverted L-shape. When the road condition is good and there is no need to clean, the baffle fixing frame 6 and the cleaning baffle 8 can be manually lifted upwards by the adjustment rod 7. After the adjustment rod 7 slides to the upper end along the snap slot 101, it slides horizontally and snaps into the snap slot 101. Thus, the baffle fixing frame 6 and the cleaning baffle 8 are lifted and confined to the cleaning base 1 by the adjustment rod 7, allowing the robot 11 to move quickly. A travel switch 9 is fixedly installed on the rear side of the cleaning baffle 8 on the side of the slider 5. The travel switch 9 is electrically connected to the control center of the robot 11. The travel switch 9 can be used to detect the deformation of the cleaning baffle 8 during the working process. If a large obstacle is encountered and the cleaning baffle 8 is compressed and deformed too much, the travel switch 9 will be triggered, and the travel switch 9 will feed back a signal to the robot 11 to remind the staff to intervene manually.
