Description

Technical Field

[0001] The invention relates to the technical field of table tennis ball sorting and disinfection, in particular to a device for quickly sorting table tennis balls by disinfection and sterilization. Background Art

[0002] Table tennis is a world popular ball sports event, including attack, confrontation and defense; the game is divided into several types such as team, singles and doubles. Table tennis is spherical, white or orange, made of celluloid or plastic.

[0003] Table tennis is a sport that is easy to play and highly accessible. It is a full-body sport that is good for your body, mind and heart. It is both a physical and entertaining sport. Multi-ball training is a common and effective training method. During multi-ball training, a large number of table tennis balls will be scattered all over the floor. Because there are so many table tennis balls, and each ball falls to the ground, a lot of dust will be generated when it falls to the ground. When performing table tennis training, a large number of table tennis balls are needed (generally, each table needs to be equipped with at least 100 table tennis balls). If manual cleaning is used, the workload will be large.

[0004] The relevant research on applying artificial intelligence to the field of culture and sports has just emerged, and there has been relatively little research on ball-picking robots. Domestic research on ping-pong ball-picking robots is still in its infancy, and there are no mature systematic results. Current research mainly focuses on the robot's mechanical structure design and ping-pong ball detection and identification.

[0005] The ping-pong ball picking robot designed in the prior art based on stm32 uses a camera to identify and locate the ping-pong ball and avoids obstacles with the help of ultrasound. This robot only relies on the direction of the detected ping-pong ball to control the robot movement, and its intelligence is not high. The ping-pong ball picking robot mainly focuses on the design of the control system, and only has a simple implementation for the ping-pong ball detection and obstacle avoidance functions, and its reliability is not high. The principle of detecting ping-pong balls and navigation control in the prior art has been simulated and tested, but no physical design has been carried out.

[0006] In the category of ball picking robots, there are many studies on tennis ball picking robots in China, and most of the research directions are concentrated in the design of robotic arms, machine vision and path planning. The research content is more about the recognition and classification of balls and obstacles, path selection and motion control.

[0007] Overseas, research on ping-pong ball picking robots is also somewhat limited. Seong Ho Yeon and others designed a complete system that includes ping-pong ball detection, environmental perception, navigation, and ping-pong ball picking modules. The disadvantage is that it does not realize the positioning and ball picking sequence planning functions, and the structure is complex and not very practical. In the category of ball picking robots, the academic field is still more focused on machine vision and mechanical design, focusing on the ability to identify and pick up ping-pong balls, and there is also a small amount of research on the overall system; in the commercial field, ball picking robots are booming, and golf ball picking robots The Ball Picker and tennis ball picking robots Tennibot have been launched. These scenes are relatively large compared to table tennis venues, and the robot's operation restrictions are relatively small. There is no need to consider problems such as obstacle avoidance, and the research and development difficulty is relatively low.

[0008] In general, the current research on ball-picking robots mainly focuses on machine vision, design of ball-picking manipulators, path planning, and design of robot mechanical structures, and there is still a lot of room for development.

[0009] In addition, a Chinese patent discloses a ball-picking device for table tennis training (application number: CN201821844369.0), which is provided with a bottom plate; four rollers are fixed to the lower end of the bottom plate by bolts; a water tank is fixed to the left side of the upper end of the bottom plate by bolts, an ultrasonic generator is fixed to the bottom end of the water tank by bolts, a fan is fixed to the right end of the upper side of the bottom plate by bolts, the upper end of the fan is connected to a first hose, the right end of the fan is connected to a second hose, and the other end of the second hose is connected to a ball-sucking nozzle. The present invention can suck the table tennis ball from the ball-sucking nozzle through the fan and transfer it to the inside of the water tank, which is convenient for collecting the table tennis ball. The table tennis ball in the water tank can be cleaned by the ultrasonic generator. Under the vibration of the ultrasonic wave, water enters the inside of the table tennis ball from the damaged part of the damaged table tennis ball, so that the damaged table tennis ball sinks to the bottom of the water tank and the intact one floats on the water surface, thereby separating the damaged table tennis ball from the intact one, which is convenient for selection.

[0010] Although the prior art discloses sorting and collecting of table tennis balls, it does not involve dust cleaning and disinfection of the table tennis balls.

[0060] Compared with the prior art, the present invention has the following beneficial effects: the present invention is provided with a visual camera 30, a universal movable wheel 22, a ball storage tank 2, a ball suction tube 4, an ultraviolet disinfection lamp 5 and an exhaust fan 6. After the visual camera 30 locates and captures the ping-pong ball dropped on the ground, the device moves to the side of the ping-pong ball 29 under the action of the universal movable wheel 22. The ping-pong ball 29 is sucked into the ball storage tank 3 through the ball suction tube 4 under the action of the exhaust fan 6. The ultraviolet disinfection lamp 5 disinfects the ping-pong ball 4. The vibration motor 10 vibrates, so that the dust on the surface of the ping-pong ball 29 is shaken off and falls into the dust collection box 11, thereby realizing rapid cleaning and disinfection of the ping-pong ball 29, without the need for manual cleaning and disinfection, reducing manual labor and improving the efficiency of cleaning and disinfection.

[0061] Working principle:

[0062] When in use, the visual camera 30 takes a picture of the ping-pong ball 29 dropped on the ground, identifies and analyzes it through the picture recognition module 31, and then feeds back the relevant information (the position distance and coordinates of the ping-pong ball) to the control board. The control board 18 respectively gives work instructions to the universal moving wheel 22 (hub motor 33 and steering motor 32), the exhaust fan 6, the vibration motor 10, and the ultraviolet disinfection lamp 5. The device moves to the side of the ping-pong ball 29 under the action of the universal moving wheel 22. The ping-pong ball 29 is sucked into the ball storage tank 3 through the ball suction tube 4 under the action of the exhaust fan 6. The ultraviolet disinfection lamp 5 disinfects the ping-pong ball 4, and the vibration motor 10 vibrates, so that the dust on the surface of the ping-pong ball 29 is shaken off and falls into the dust collection box 11, thereby realizing the rapid cleaning and disinfection of the ping-pong ball 29.

[0063] Disinfection function principle: Use ultraviolet light for sterilization and disinfection. Ultraviolet light with a wavelength of 240-280nm is most effective in destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing growth cell death and (or) regenerative cell death, achieving the effect of sterilization and disinfection. Especially when the wavelength is 253.7, the bactericidal effect of ultraviolet light is the strongest; ultraviolet light has a strong bactericidal effect, but its ability to penetrate objects is very weak. It is suitable for space disinfection in operating rooms, burn wards, infectious disease wards and sterile rooms, as well as disinfection of heat-sensitive items and surfaces.

[0064] Identification, positioning and movement principles: Using the visual camera 30, the distance between the identified ping-pong ball 29 and the device can be directly obtained, and then the coordinates of the ping-pong ball 29 can be obtained through some specific coordinate conversions (after the visual camera 30 captures the ping-pong ball 29, the infrared sensor and the laser ranging sensor measure the distance of the ping-pong ball, and the built-in system of the control board establishes a reference system, for example, the device body is set as the origin, the distance between the ping-pong ball 29 and the device is a value M on X or Y, and then the control board 18 drives the universal wheel to move M in the X or Y axis direction). The whole process is simple to implement, and the positioning is relatively accurate, and it is also relatively economical in engineering practice; various sensors (infrared sensors and laser ranging sensors, among which infrared sensors and laser ranging sensors are used to sense the walking of pedestrians) are used at the same time. The movement and obstacle situation of the device, if there is an obstacle in front during the walking process, it will be fed back to the control board 18, and the control board will issue a stop working instruction to the universal moving wheel 22, and the built-in system of the control board 18 will recalculate the coordinates according to the original coordinate position of the original table tennis ball 29, and then feed back the coordinate data to the control board 18 again. The control board 18 feeds back the coordinate walking data to the universal moving wheel 22, and then the device changes lanes and moves to the table tennis ball 29. The calculation and analysis speed of the control board 18 is relatively fast. When encountering an obstacle, the movement of the universal moving wheel 22 will be delayed by about one or two seconds), ensuring automatic path finding in the process of picking up the ball and not affecting the training of the athletes, so that the entire training scene reflects more intelligence; the movement of the entire device depends on the universal moving wheel 22, and it can move in all directions according to the instructions.

[0065] The working process is that after the switch is turned on, the table tennis ball 29 (a white or orange sphere with a diameter of 40mm±0.05) is identified by the visual camera 30. After positioning is completed, the table tennis ball 29 is moved from near to far to the destination by the omnidirectional wheels, and the table tennis ball 29 is sucked into the device for dust removal. Finally, the ultraviolet disinfection lamp 5 is used for ultraviolet disinfection. After the disinfection is completed, the indicator light prompts the completion of disinfection; the cleaned and disinfected table tennis ball 29 is manually taken out for teaching and training.

[0066] Another implementation mode of the present invention is as follows: when working, the device of the present invention is placed in a table tennis ball placement bucket 28, the table tennis ball 29 to be cleaned and disinfected is put into the table tennis ball placement bucket 28, the control switch 21 is started, the exhaust fan 6, the ultraviolet disinfection lamp 5 and the vibration motor 10 start working (while ensuring that the sealing door is closed), the exhaust fan 6 allows air to enter the ball suction pipe 4 from the ball suction port 8, and then enter the base 1 through the air inlet 24 on the base 1, and then be discharged from the exhaust port 7, so that the table tennis ball 29 is under the negative pressure of the air. The ball is sucked into the cover 2 from the ball suction port 8 through the ball suction tube 4 and then falls into the ball storage tank 3. The ultraviolet disinfection lamp 5 generates ultraviolet light to disinfect the ping-pong ball 29. The vibration motor 10 works to shake off the dust adhering to the ping-pong ball 29 and drop it into the dust collection box 11 through the filter screen 9. After the cleaning and disinfection is completed, the control switch 21 is closed, and then the sealing door 13 is opened to take out the ball storage tank 3, take out the cleaned and disinfected ping-pong ball 29, and also take out the dust collection box 11 to dump the dust.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
