[0002] During underground conveyor belt transportation in coal mines, hard foreign objects such as anchor bolts, sleepers, and large pieces of gangue mixed in with the materials can easily scratch or tear the conveyor belt, causing shutdowns and production stoppages.

[0003] Existing machine vision sorting equipment faces extremely high dust concentrations underground, making it easy for coal dust to accumulate on camera lenses and supplementary lighting lenses, resulting in blurred images, missed or incorrect detection of foreign objects. Moreover, existing cleaning methods are ineffective, easily accumulating dust and further compromising detection and protection. Therefore, there is a need for a smart identification and grasping mechanism for foreign objects on mining conveyor belts with dust removal imaging to solve the above problems.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6 This invention provides a technical solution: an intelligent foreign object identification and grasping mechanism for mining conveyor belts with dust removal imaging, comprising an image acquisition box 1, an XYZ three-axis moving mechanism 2, a mining explosion-proof control box 3, an explosion-proof server 4, an electric push rod 5, a storage battery 6, a high-speed industrial camera 7, a protective baffle 8, a compressed air source pipe 9, a supplementary light 10, a stepper driver 11, a solenoid valve 12, an exhaust fan 13, a lifting ring 14, a heat sink 15, supporting feet 16, a damping block 17, a blowing assembly 18, an inner pad 19, and a protective... The image acquisition box 1 has an XYZ three-axis moving mechanism 2 on one side, and a mine explosion-proof control box 3 and an explosion-proof server 4 are distributed in front of the XYZ three-axis moving mechanism 2. The image acquisition box 1 is made of die-cast aluminum alloy, and a lifting ring 14 is fixedly connected to the upper corner of the image acquisition box 1. The lifting ring 14 is arranged in four rectangular groups at the upper end of the image acquisition box 1, and the inner side of the lifting ring 14 is made of rubber pad material. This allows the image acquisition box 1 to be effectively explosion-proof and to be stably lifted and operated through the lifting ring 14.

[0019] A battery 6 is fixedly connected to the upper part of the inner wall of the image acquisition box 1, and a heat sink 15 is embedded in the middle of the upper part of the image acquisition box 1. The heat sink 15 is close to the battery 6 and is made of copper alloy. This allows the battery 6 to provide backup power, operate stably, and effectively dissipate heat. A high-speed industrial camera 7 is installed in the middle of the lower part of the inner side of the image acquisition box 1, and supplementary lights 10 are distributed on the outside of the high-speed industrial camera 7. The supplementary lights 10 and the high-speed industrial camera 7 are arranged in a double-layer concentric distribution on the outside of the high-speed industrial camera 7. The supplementary lights 10 and the high-speed industrial camera 7 are close to the protective cover 20. The protective cover 20 is made of special weather-resistant, non-stick, and high-transparency glass. This allows the supplementary lights 10 to provide stable supplementary light and can be protected by the protective cover 20, and can also effectively prevent dust accumulation.

[0020] In one embodiment, a protective cover 20 is fixedly connected to the lower middle of the image acquisition box 1, and an electric push rod 5 is fixedly connected to the lower corner of the image acquisition box 1. A support foot pad 16 is fixedly connected to the output end of the electric push rod 5, and a damping block 17 is fixedly connected between the support foot pads 16. The support foot pads 16 are connected to each other through the damping block 17 in a damping support connection. This allows the support foot pads 16 and the damping block 17 to effectively reduce shock and ensure stable placement. The support foot pads 16 and the damping block 17 are connected to the image acquisition box 1 in a lifting and lowering motion through the electric push rod 5 and the stepper driver 11. This allows the support foot pads 16 and the damping block 17 to achieve high-precision synchronous operation and independent adjustment of a single unit at the same time, with good placement adaptability.

[0021] Furthermore, a stepper driver 11 is electrically connected to one side of the electric push rod 5, and a protective baffle 8 is fixedly connected between the electric push rods 5. The protective baffle 8 is distributed in a wrapping position at the lower end of the image acquisition box 1, and an inner pad 19 is attached and fixed to the inner side of the protective baffle 8. The inner pad 19 is made of nano-ceramic anti-stick coating material, so that the protective baffle 8 can be covered and protected, and the dust can be guided by the anti-sticking of the inner pad 19.

[0022] In one embodiment, a blowing assembly 18 is installed inside the front side of the protective baffle 8, and one end of the blowing assembly 18 is connected to a solenoid valve 12. The blowing assembly 18 is arranged in a matrix with an inclined distribution inside the protective baffle 8, and the blowing assembly 18 is connected to the compressed air source pipe 9 through the solenoid valve 12 in an open-closed manner. This allows the blowing assembly 18 to perform matrix blowing, resulting in a good dust removal effect. The other end of the solenoid valve 12 is connected to the compressed air source pipe 9. An exhaust fan 13 is installed at the rear side of the protective baffle 8. An inner pad 19 is attached to the inner side of the baffle 8. The exhaust fan 13 is connected to the protective baffle 8 in a suction connection, and the exhaust fan 13 is distributed in a matrix on the protective baffle 8. This allows the exhaust fan 13 to help to remove dust and avoid dust accumulation, which would affect imaging. The XYZ three-axis moving mechanism 2, the mine explosion-proof control box 3, the explosion-proof server 4, the electric push rod 5, the storage battery 6, the high-speed industrial camera 7, the supplementary light 10, the stepper driver 11, the solenoid valve 12, and the exhaust fan 13 are electrically connected.

[0023] Working principle: When using this intelligent identification and grasping mechanism for foreign objects on mining conveyor belts with dust removal imaging, the image acquisition box 1 of the device is first hoisted and transported by the hoisting ring 14, and then matched and placed with the XYZ three-axis moving mechanism 2. It can be supported by the support feet 16 and the damping blocks 17 for shock absorption. Then, the height is adjusted by the electric push rod 5 and the stepper driver 11, or the overall height is adjusted. Then, the high-speed industrial camera 7 and the supplementary light 10 are used for supplementary light image detection. Then, the compressed air source pipe 9 can supply high pressure air to the blowing component 18, which blows air onto the protective cover 20 to remove dust. The dust is then extracted by the exhaust fan 13 and is started on a timer. The inner wall of the protective baffle 8 can be protected by the inner pad block 19 to prevent dust from sticking. When the power supply is unstable, it can be powered by the battery 6 to continue operation. This is the usage process of this intelligent identification and grasping mechanism for foreign objects on mining conveyor belts with dust removal imaging.
