Specific instructions for use:

In one embodiment, the working principle of the borrowing process:

After the user clicks the button of "borrow basketball" (or "borrow football", "borrow volleyball") on the touch screen, the Arduino microcontroller 145 receives the signal from the touch screen, and then transmits the control instruction to the corresponding stepping motor Driver: After the stepping motor driver receives the signal, it drives the corresponding second stepping motor 111 to rotate forward, and through the transmission of the ball-out control mechanism, the front end ball blocking plate 120 is controlled to slide downward, and the rear end ball blocking plate 121 is controlled to move upward. Sliding; The ball that is positioned at the bottommost bottom of the ball storage track of the ball storage system then rolls out of the ball storage system 2 under the action of the ball control mechanism and its own gravity, enters the inclined rail dribbling mechanism 96 of the borrowing system, and the back The ball cannot roll forward due to the restriction of the rear end baffle plate 121, so that each blue ball can be rolled out of the ball storage system 2 in turn; the exit sensor 139 on the ball storage system 2 detects that the ball passes by, and it will be fed back to the control system. part of the corresponding signal. This signal has three functions: one is as a detection signal that the ball has rolled out of the ball storage system 2, and the corresponding ball storage quantity will be reduced by one, and the control part calculates the remaining ball storage volume, and feeds back to the touch screen for the user Query, if the ball has been borrowed, the touch screen will display the information of "the ball has been borrowed" for the user to know; the second is that this signal is used as the reset signal of the ball borrowing system's ball control mechanism 97, and the ball borrowing system's ball control mechanism After 97 got this signal, the second stepping motor 111 reversely rotated, and by the transmission of the ball-out control mechanism 97 of the borrowing ball system, the front end ball stopper 120 was controlled to slide upwards, the rear end ball stopper 121 was controlled to slide downwards, and the back end ball stopper 121 was controlled to slide downwards. The ball supplements forward, and stops rolling under the blocking effect of the front end ball baffle plate 120, and waits for the instruction of borrowing the ball next time; the third is that this signal is used as the starting signal of the ball borrowing system 5 to borrow the goal mechanism 98, and after the control mechanism obtains this signal, The second motor 130 of the borrowed goal mechanism 98 will send a starting signal to perform the opening task of the borrowed goal, allowing the ball to roll out of the machine inside smoothly. After the ball rolled out of the ball storage system 2, the three effects of the feedback signal came into effect immediately, that is, the amount of ball storage decreased by one, the ball borrowing system 5 and the ball control mechanism 97 reset, and the borrowing goal was opened; the ball coming out from the ball storage system 2 can be Roll forward on the inclined guide rail of the inclined rail dribbling mechanism 96 by self gravity, and arrive at the position of borrowing the goal. The goal of borrowing has just carried out the door-opening action the moment the ball rolled out of the ball storage system 2, so the ball smoothly passes through the goal mechanism 98 of the borrowing system and arrives in the ball-out groove 15 of the front plate 7. At the same time, the borrowed goal executes the closing action under the control of the time control method and reaches the initial position. At this point, the user can take away the ball and perform sports.

In one embodiment, the working principle of the ball returning process:

After the user clicks the button of "return basketball" (or "return football", "return volleyball") on the touch screen, the touch screen prompts "please scan the bar code", and the user aligns the bar code on the returned ball with the bar code on the shell 1. bar code scanner 12, after the control part obtains the data of the returned ball transmitted by the scanner, this data is matched with the data in the database, and whether the ball is checked for a machine ball, if it is detected as a non-machine ball, it is returned The first motor 88 of the goal mechanism 60 of the ball system 4 will not run, and the return goal will not open. The touch screen will prompt "The ball is not for the machine and cannot be returned. Please return the ball for the machine." If it is detected as a ball for the machine, the Arduino The microcontroller 144 will send a signal to the first motor 88 of the goal mechanism 60 of the ball returning system 4 . Under the action of the belt transmission of the first motor 88, the return goal is opened, and the touch screen prompts "please put the ball in", and the user puts the returned ball into the detection system 3 inside the machine; the returned ball is put into the detection system 3. On the screening bowl 45 of the screening actuator 33, the bowl-shaped design helps to improve the stability of the ball during the detection process. The detection system 33 and the detection mechanism 32 judge whether the returned ball is damaged through pressure detection. In the present invention, the judgment standard of the damage is the deflated degree of the ball. The push rod motor 37 has three different propulsion values according to the detected ball type. The push rod motor 37 slowly pushes the ball pressing plate 39 forward to extrude the returned ball, and when the propulsion value of the designed ball is reached, the propulsion is stopped, and the returned ball will extrude the ball blocking plate 40, and finally the pressure will be applied to the On the pressure sensor 41, the pressure sensor 41 obtains a series of pressure data, and feeds back to the database established inside the control part that contains the pressure range value data. The database has reasonable pressure value range data for three kinds of balls. The pressure value range is divided into three gears: low gear, middle gear, and high gear, which correspond to the deflated degree of the ball. Specifically, the low gear means the pressure value is small, and the ball The ball is highly deflated, and the ball is severely damaged and cannot be used any longer; the middle gear means that the pressure value is moderate, the ball is deflated to a moderate degree, the ball may be insufficient, but it can continue to be used, but the use effect is reduced; the high gear means that the pressure value is larger , The degree of deflation of the ball is low, the ball is played well without damage, and can continue to be used. The database compares the pressure data fed back by the sensor with its own pressure value range data, and judges the range of the pressure data, which can determine whether the detected ball is damaged. Taking borrowing and returning basketball as an example, the returned ball is put into the screening bowl 45 of the screening actuator 33 of the detection system 3, and the push rod motor 37 stops advancing after performing detection of the propelling value of the basketball. By pressing the ball plate 39, extruding the returned ball, and the pressure transmission of the ball blocking plate 40, the pressure sensor 41 obtains a series of pressure data, and the database compares the pressure data with the basketball pressure value range data corresponding to itself. If the pressure data is in the low gear, the ball will be severely damaged and cannot be used any longer; if the pressure data is in the middle gear, the ball may be insufficient in gas, but you can continue to use it, but the use effect will be reduced; if the pressure data is in the high gear, the ball will play well No loss, can continue to use. At this point, the execution of the ball detection task is completed. The different detection results of the detection mechanism 32 of the detection system 3 correspond to the different execution actions of the goal mechanism 60 of the ball returning system 4 , the different execution actions of the screening actuator 33 of the detection system 3 and the different operation prompts of the touch screen. If the detection mechanism 32 judges that the returned ball is seriously damaged and cannot be used, then the goal mechanism 60 of the ball returning system 4 will not perform the door closing action, and the screening motor of the screening actuator 33 will rotate forward, and the ball in the screening bowl 45 will be rotated forward through transmission. The returned ball can be pushed to the outside of the machine, and the returned ball rolls on the second swash plate 91.1. The ball has rolled into the retaining bowl 144 on the machine shell, and simultaneously the touch screen displays "The ball is damaged and cannot be returned, please return it to the sporting goods management center", then, the screening motor of the screening actuator 33 is reset, the screening bowl is reset, and the ball is returned. The system goal mechanism executes the door-closing action; If the detection mechanism 32 judges that the returned ball gas is insufficient, but can continue to be used, then the ball returning system 4 goal mechanism 60 will not perform the door-closing action, and the screening motor 44 of the screening actuator 33 is just Turn, through the transmission, the returned balls in the screening bowl 45 will be pushed to the outside of the machine, the returned balls will roll on the second inclined plate 91.1, and the balls will roll into the retaining bowl 144 on the machine shell 1, while the touch screen Display " ball air pressure is insufficient, influences use, please return after inflating ", then, the screening motor 44 of screening actuator 33 resets, and screening bowl is reset, and ball returning system 4 enters goal mechanism 60 and performs closing action. The user can use the pump to inflate the ball and return it again; if the detection mechanism 32 judges that the returned ball is intact and can be used continuously, the ball return system 4 enters the goal mechanism 60 to perform the door closing action, and the selection of the actuator 33 is performed. The motor 44 reverses, and by transmission, the returned balls in the screening bowl 45 can be pushed towards the inside of the machine. The returned ball rolls into the ball-returning system 4 unloading mechanism 59, and the touch screen displays "returning the ball successfully". Then, the screening motor 44 of the screening actuator 33 resets to reset the screening bowl 45; The initial state of is low on the left and high on the right, which is convenient for accommodating the ball. When the returned ball enters the ball returning system 4 unloading mechanism 59, it will hit the high baffle plate 77 to limit the forward rolling of the ball. The baffle plate 78 limits the rolling of the ball to the left. Since the initial state of the ball unloading mechanism 59 is low on the left and high on the right, the ball leans to the left under the action of gravity, so it will not roll to the right. Ball has just stopped in the ball unloading mechanism 59 stably. The first stepping motor 62 of the ball returning system 4 dribbling mechanism 58 drives the screw mandrel 61 installed on the ball returning system 4 dribbling mechanism 58 to move towards the direction of the ball storage track through transmission. When the position detection sensor 142 of the screw mandrel 61 senses When the signal is reached, the first stepping motor 62 stops rotating. The steering gear 70 of the ball-returning system 4 unloading mechanism 59 is by transmission, drives the corresponding structure of the unloading mechanism 59 to rotate upwards, unloads the returned ball, and the ball rolls into the ball storage system 2. Then the first stepping motor 62 of the ball-returning system 4 dribbling mechanism 58 starts a reset action, and the unloading mechanism is reset to the initial position.

In this embodiment, the Arduino microcontroller integrates the control design of 3 different types of motors, which can control push rod motors, stepper motors, and steering gears. In the present invention, the push rod motor is used for the detection mechanism of the detection system to push the balls, the pressure sensor transmits the signal to the control system, and the control system judges whether it is good or bad, and sends it to the detection system to filter the execution instructions of the different screening motors of the actuator. , to discharge the ball or send the ball into the dribbling mechanism. After the ball is sent to the dribbling part, the first stepping motor drives the ball returning system to move the dribbling mechanism. The position detection sensor judges the position of the dribbling mechanism and reaches the specified position. After the position, the sensor sends a signal to the control system, the control system sends an instruction to the steering gear, the steering gear drives the ball unloading mechanism to unload the ball to be returned, and the ball enters the ball storage system.

The above embodiments are only to illustrate the technical conception and characteristics of the present invention, and its purpose is to allow those skilled in the art to understand the content of the present invention and implement it, and cannot limit the protection scope of the present invention. All equivalent changes or modifications should fall within the protection scope of the present invention.
