Abstract
Description
Technical Field
[0001] This utility model relates to the field of AMR (Automatic Transporter) robot technology, specifically an anti-collision device for AMR robots. Background Technology
[0002] AMR (Autonomous Mobile Robot) is a comprehensive autonomous mobile robot system that integrates multiple functions such as environmental perception, dynamic decision-making and planning, behavior control, and execution. It does not rely on external navigation markers such as magnetic strips or QR codes, and can autonomously perceive its surroundings, plan paths, and avoid obstacles. It is widely used in manufacturing, warehousing and logistics, healthcare, and other fields to achieve efficient and flexible material handling and automated task execution.
[0003] Current AMR (Automatic Mobile Transporter) robots use visual sensors around their perimeter to perceive their surroundings in real time and avoid obstacles. However, visual sensors may have detection errors or encounter sudden obstacles, which can easily lead to malfunctions or damage to the AMR robot. Furthermore, the goods being transported may be thrown out due to inertia and damaged, resulting in economic losses. Utility Model Content
[0004] The purpose of this invention is to provide an anti-collision device for an AMR handling robot, which effectively solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution.

The mounting shell is disposed on the outside of the transport robot, and a collision avoidance shell is disposed on the outside of the mounting shell. Rectangular frames are mounted on all four outer surfaces of the mounting shell. Two parallel sliding rods are installed inside the rectangular frames. Slider blocks are slidably mounted on the outer surfaces of the two sliding rods. Hydraulic damping rods are mounted on the outer surfaces of the sliders, with the ends of the hydraulic damping rods connected to the collision avoidance shell. A spring A is sleeved on the outer surface of the hydraulic damping rod, with both ends of spring A abutting against the slider and the collision avoidance shell, respectively. Clamping mechanisms are provided on both sides of the upper surface of the mounting shell.
[0007] Furthermore, the clamping mechanism includes a fixed plate mounted on the upper surface of the mounting housing, an electric push rod mounted on the outer surface of the fixed plate, the end of the telescopic end of the electric push rod extending through to the other side of the fixed plate and mounting a clamping plate, and vision sensors are provided on the opposite surfaces of the two fixed plates.
[0008] Furthermore, side blocks are installed on both sides of the fixing plate, and limit rods are installed through the inside of the side blocks, with the ends of the limit rods connected to the clamping plate.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.
[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0026] Please see Figures 1-5This utility model provides an anti-collision device for an AMR handling robot, including a handling robot 100 and a mounting shell 101. The mounting shell 101 is disposed on the outside of the handling robot 100, and an anti-collision shell 102 is disposed on the outside of the mounting shell 101. Rectangular frames 103 are installed on the four outer surfaces of the mounting shell 101. Two parallel sliding rods 104 are installed inside the rectangular frames 103. Slider blocks 105 are slidably mounted on the outer surfaces of the two sliding rods 104. Hydraulic damping rods 106 are installed on the outer surfaces of the sliders 105. The ends of the hydraulic damping rods 106 are connected to the anti-collision shell 102. Springs A107 are sleeved on the outer surfaces of the hydraulic damping rods 106, and the two ends of the springs A107 abut against the sliders 105 and the anti-collision shell 102, respectively. Clamping mechanisms 200 are provided on both sides of the upper surface of the mounting shell 101.
[0027] When in use, the goods are placed on the handling robot 100 for handling. The two sides of the goods can be clamped and fixed by the clamping mechanisms 200, which can prevent the goods from falling due to vibration during handling and centrifugal force generated when turning.
[0028] When the anti-collision shell 102 collides with other objects, it compresses the hydraulic damping rod 106 and the spring A107. Through their combined action, they can buffer the impact of the collision on the handling robot 100 and the goods being handled, reducing the possibility of malfunctions or damage to the handling robot 100. Furthermore, because the goods are held by the clamping mechanism 200, the inertia caused by the goods can be prevented from being thrown out and damaged, thus reducing economic losses.
[0029] Because the slider 105 is slidably mounted on the slide rod 104, the slider 105 can drive the hydraulic damping rod 106 to move horizontally. Therefore, it can provide a buffering effect when a collision occurs at any angle on the anti-collision shell 102, providing comprehensive protection.
[0030] Preferably, the clamping mechanism 200 includes a fixing plate 201 mounted on the upper surface of the mounting housing 101. An electric push rod 202 is mounted on the outer surface of the fixing plate 201. The end of the telescopic end of the electric push rod 202 extends through to the other side of the fixing plate 201 and is fitted with a clamping plate 203. Visual sensors are provided on the opposite surfaces of the two fixing plates 201.
[0031] When goods are placed on the handling robot 100, the vision sensor detects the goods and then activates the electric push rod 202 to drive the clamping plate 203 to extend outward and press against the outer surface of the goods to achieve the purpose of clamping and fixing. After the goods are moved to the designated position by the handling robot 100, the electric push rod 202 drives the clamping plate 203 to retract and separate from the goods, so that the goods can be taken out.
[0032] Preferably, side blocks 300 are installed on both sides of the fixing plate 201, and a limit rod 301 is provided through the inside of the side block 300, and the end of the limit rod 301 is connected to the clamping plate 203.
[0033] The side block 300 provides a limiting function for the clamping plate 203, making it more stable when clamping goods.
[0034] Preferably, a battery 400 is provided on the outer surface of the fixing plate 201, and the battery 400 is electrically connected to the electric push rod 202.
[0035] The battery 400 provides power to the electric push rod 202 to ensure its normal use. The electric push rod 202 has its own power supply and does not consume the internal power of the handling robot 100, thus having a small impact on the working time of the handling robot 100.
[0036] Preferably, the top of the mounting shell 101 is provided with a side strip 500, and bolts 501 are installed on all four sides of the mounting shell 101.
[0037] With the side strip 500, the mounting shell 101 can be fitted onto the outside of the handling robot 100 without falling off, and the four bolts 501 can be tightened to press against the outer surface of the handling robot 100. Thus, the mounting shell 101 can be installed and removed without changing the structure of the handling robot 100, making it convenient to use.
[0038] Preferably, the mounting shell 101 has through holes A600 on all four sides, and the anti-collision shell 102 has through holes B601 on all four sides.
[0039] The through holes A600 and B601 ensure that the mounting shell 101 and the anti-collision shell 102 do not obstruct the visual sensors around the handling robot 100, enabling them to function normally and provide obstacle avoidance capabilities.
[0040] Preferably, two springs B700 are sleeved on the outer surface of the slider 104, and the two springs B700 are respectively disposed on both sides of the slider 105.
[0041] When the anti-collision shell 102 is involved in a collision, the sliders 105 on the other two sides will slide on the slide bar 104 and compress the spring B700, thereby further providing a cushioning effect. After the collision ends, the spring B700 can also improve the reset effect of the slider 105, so that it is in the middle position on the slide bar 104.
[0042] Preferably, the outer surface of the clamping plate 203 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip texture.
[0043] By using rubber pads and anti-slip textures, the friction between the clamping plate 203 and the surface of the goods is increased, resulting in a better clamping effect. In addition, the rubber pads act as a buffer between the clamping plate 203 and the goods, preventing damage to the goods.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
