In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0035] like Figure 1-Figure 6 The device for automatically arranging and serving badminton balls based on the uneven distribution of gravity comprises a frame 1, a collecting mechanism, a dribbling mechanism and a serving mechanism.

[0036] like Figure 1-Figure 3 As shown, the collecting mechanism includes a collecting funnel 2, a roller 3 and a first driving member. The collecting funnel 2 is fixed on the frame 1. The upper side of the collecting funnel 2 is provided with a feeding port, and the bottom is provided with a discharge port. Two rollers 3 arranged side by side are provided at the discharge port. The rollers 3 are rotatably connected to the frame 1. The first driving member is connected to the two rollers 3 to drive the two rollers 3 to rotate towards each other.

[0037] Here, after two rollers 3 are arranged at the discharge outlet, the falling of the badminton from the collecting funnel 2 can be controlled. For example, when the two rollers 3 do not rotate, the two rollers 3 block the discharge outlet and the badminton cannot fall; when the rollers 3 rotate, the badminton can be driven to fall from between the two rollers 3.

[0038] In this embodiment, if Figure 3 As shown, the first driving member includes a first motor 13, a driving gear 14 and a driven gear 15. One of the two rollers 3 is provided with a driving gear 14, and the other is provided with a driven gear 15. The driving gear 14 meshes with the driven gear 15, and the motor is connected to the driving gear 14, so that the first motor 13 can drive the two rollers 3 to rotate through the transmission of the driving gear 14 and the driven gear 15. Of course, those skilled in the art can also use other driving methods to realize the rotation of the rollers 3, which is not limited here.

[0039] Further, in order to facilitate the discharge of badminton, as Figure 3 As shown, the discharge port is a strip-shaped port extending in the front-to-back direction, the roller 3 extends in the front-to-back direction, and two rollers 3 are arranged at the discharge port, one on the left and one on the right.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, the transport mechanism includes a conveyor 4 and an upper ball cylinder 5. The conveyor 4 is inclined on the frame 1 with a higher front and a lower back. The conveyor 4 is located below the collecting funnel 2. The conveyor 4 is used to transport badminton from the back to the front. The upper ball cylinder 5 is fixed on the frame 1 and is located at the front end of the conveyor 4. The rear side of the upper ball cylinder 5 is provided with a goal entrance 6, and the bottom is provided with a volleyball opening.

[0041] Specifically, the conveyor 4 in this embodiment uses a belt conveyor 4, which uses a belt conveyor. The belt is relatively soft, and the badminton is not easy to bounce when it falls on the belt. The badminton in the prior art mainly includes two parts, a ball support part at the bottom and a feather part at the top. The ball support part is heavier than the feather part. Therefore, when the badminton falls from the collecting funnel 2, under the action of gravity, the ball support part at the bottom will always face downward and contact the belt below first.

[0042] Since the conveyor 4 is arranged on the frame 1 with the front higher and the back lower, and conveys from the back to the front, when the ball holder contacts the belt, the belt will give the ball holder a forward force, so that after the badminton falls on the belt, it will be tilted, with the ball holder facing forward and the feather part facing backward, and in this posture, they are sent to the upper ball cylinder 5 one by one. Finally, when the feather part is discharged from the ball discharge port of the upper ball cylinder 5, it is in a normal posture with the ball holder at the bottom and the feather part at the top, thereby completing the automatic sorting of the badminton.

[0043] In this embodiment, in order to ensure that the badminton can fall smoothly onto the conveyor 4, Figure 2 and Figure 3 As shown, a ball baffle plate 10 is respectively provided below the two rollers 3 , and the ball baffle plate 10 is located above the conveyor 4 .

[0044] In this embodiment, in order to ensure that the badmintons on the conveyor 4 can be sent to the upper ball cylinder 5 one by one, as shown in FIG. Figure 4 and Figure 5 As shown, a vertical guide plate 11 is respectively provided on the left and right edges of the ball opening 6. The guide plate 11 is arranged parallel to the top of the conveyor 4 and is fixedly connected to the frame 1. The distance between the two guide plates 11 is continuously expanded backwards.

[0045] like Figure 5 and Figure 6 As shown, the serving mechanism includes a lower ball barrel 7, a launching wheel 8, a second driving member and a third driving member. There are two launching wheels 8 which are arranged side by side on the frame 1. The second driving member is connected to the launching wheels 8 to drive the two launching wheels 8 to rotate towards each other. The lower ball barrel 7 is a conical barrel that is larger at the top and smaller at the bottom and matches the shape of a badminton. The lower and upper sides of the lower ball barrel 7 are open. A serving port 9 is provided on the front side of the lower ball barrel 7. The third driving member is connected to the lower ball barrel 7 to drive the lower ball barrel 7 to reciprocate between a ball receiving position and a serving position.

[0046] At the ball receiving position, the lower ball barrel 7 is located directly below the upper ball barrel 5. At this time, when the badminton is discharged from the discharge port of the upper ball barrel 5, it will just fall into the lower ball barrel 7 below. Then at the serving position, the lower ball barrel 7 moves between the two launching wheels 8. Since the lower side of the lower ball barrel 7 is open, when the badminton falls into the lower ball barrel 7, the ball holder extends out of the lower ball barrel 7. In addition, the front side of the ball barrel 5 is provided with a serving port 9. Therefore, when the lower ball barrel 7 moves between the two launching wheels 8, the ball holder also moves between the two launching wheels 8. Therefore, after the two launching wheels 8 rotate, the badminton can be launched by high-speed rotation.

[0047] In this embodiment, in order to realize automatic control, Figure 6 As shown, a detection probe 12 is provided on the frame 1, and the detection probe 12 is used to detect whether the lower ball cylinder 7 receives a badminton when it is in the ball receiving position. The detection probe 12 used can be two infrared probes, one for emitting infrared rays and the other for receiving infrared rays. The two detection probes 12 are distributed on the left and right sides of the lower ball cylinder 7 when it is in the ball receiving position, and mainly detect whether there is a badminton in the lower ball cylinder 7 by whether the ball holder blocks the infrared rays. Once it is detected that there is a badminton in the lower ball cylinder 7, the roller 3 and the belt conveyor 4 are temporarily stopped, and the third driving member drives the lower ball cylinder 7 to move to the serving position.

[0048] In this embodiment, the launching wheel 8 is a polyurethane wheel, and the second driving member includes a second motor 16 . There are two second motors 16 , and the two second motors 16 are connected to the two launching wheels 8 in a one-to-one correspondence.

[0049] like Figure 6 As shown, the third driving member includes a third motor 17, a screw rod 18, a slider 19 and a connecting rod 20. The screw rod 18 is rotatably arranged on the frame 1, the third motor 17 is connected to the screw rod 18, the slider 19 is threadedly matched with the screw rod 18, the screw rod 18 is provided with a connecting rod 20, and the connecting rod 20 is connected to the lower ball cylinder 7. Further, in order to facilitate the control of the stroke of the slider 19 to achieve the reciprocating movement and reset of the lower ball cylinder 7, a travel switch can be arranged on the frame 1 to control the forward and reverse rotation of the third motor 17, which is a conventional setting in the field of automation and will not be described in detail.

[0050] The use of this device is as follows:

[0051] The collected badmintons are put into the collecting hopper 2, and then the first driving member and the belt conveyor 4 are turned on. The badmintons are rotated and arranged by the roller 3 and fall onto the conveyor belt of the belt conveyor 4, and then are sent to the upper ball cylinder 5 and finally fall into the lower ball cylinder 7 at the receiving position with the ball holder part at the bottom and the feather part at the top. Subsequently, the lower ball cylinder 7 moves to the serving position, and after the two launching wheels 8 rotate, the badmintons can be sent out by high-speed rotation, thereby completing the automatic arrangement and automatic serving of the badmintons. After that, the lower ball cylinder 7 is reset to prepare for receiving and serving the next badminton, which will not be described in detail.

[0052] In summary, the device is designed accordingly based on the uneven gravity distribution of badminton itself, which can realize the automatic and orderly arrangement of messy badminton and the serve with neat posture, which can greatly reduce the waiting time during badminton training and improve the training efficiency.

[0053] Although a portion of the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations to these embodiments are within the scope of protection of the claims of the present invention without departing from the principles and purpose of the present invention.
