[0030] Example:

[0031] Reference Figures 1 to 8This embodiment proposes a PLC-based simulation badminton serving machine, including a shuttlecock tube 2, a shuttlecock gripping mechanism 3, and a serving mechanism 4. A backplate 1, shaped like a human figure, is provided on the back of the shuttlecock tube 2, the gripping mechanism 3, and the serving mechanism 4. The serving mechanism 4 is located in the middle of the backplate 1. The gripping mechanism 3 and the serving mechanism 4 are jointly controlled by a PLC controller. By simulating a human figure on the backplate 1, the serving height and trajectory can be easily simulated, thus providing a training effect for users on receiving shuttlecocks, making it suitable for beginners to use and practice.

[0032] To facilitate the installation of the ball cylinder 2, the preferred back plate 1 is provided with a guide rail 5 and a locking mechanism 17. The ball cylinder 2 is slidably mounted on the guide rail 5. When the ball cylinder 2 moves to correspond with the ball grabbing mechanism 3, the locking mechanism 17 is adapted to lock the ball cylinder 2. The ball cylinder 2 slides on the guide rail 5 and is fixed by the locking mechanism 17. The ball cylinder 2 is easy to install and disassemble, thus facilitating its use.

[0033] To facilitate shuttlecock replacement, two shuttlecock tubes 2 are provided. During operation, the bottom of one shuttlecock tube 2 corresponds to the shuttlecock grabbing mechanism 3. When the shuttlecocks 11 in that shuttlecock tube 2 are used up, the shuttlecock machine is paused. At this time, the locking mechanism 17 is engaged, and the other shuttlecock tube 2 is pushed into the locking mechanism 17 and locked in place. At this time, the previously hit shuttlecocks can be loaded into the shuttlecock tube 2 that has just been released from its locking position, and the shuttlecock tube 2 can be replaced again later.

[0034] To facilitate locking, the locking mechanism 17 includes locking parts 18 and springs, and two locking parts 17 are spaced apart. The distance between the two locking parts 18 is the same as the outer diameter of the ball cylinder 2. Guide ramps are provided at both ends of the outer side of the locking parts 18. When the ball cylinder 2 slides against the locking parts 18, it interacts with the guide ramps, causing the locking parts 18 to retract and the spring to compress. In the initial state, the spring causes the locking parts 18 to extend, and the ball cylinder 2 is positioned between the two locking parts 18, forming a limit and preventing further sliding. When the ball cylinder 2 needs to be replaced, the ball cylinder 2 in the locking position is pushed. At this time, the ball cylinder 2 acts on the guide ramp at the top of the locking part 18, causing the locking part 18 to retract. The locking is now in contact, and the ball cylinder 2 can continue to slide. The empty ball cylinder 2 is then removed, and another ball cylinder 2 filled with balls is pushed between the two locking parts 18, thus completing the replacement of the ball cylinder 2.

[0035] like Figure 1 , Figure 5 As shown, this ball-serving machine also includes a moving mechanism 7, which is located at the bottom of the back plate 1. The moving mechanism 7 includes motor-driven rollers 14. The motor drives the rollers 14, and three rollers 14 can be arranged in the left, right, and front directions. When only one of the left and right rollers 14 is driven, it can move left and right. When both left and right rollers 14 move simultaneously, it can move straight.

[0036] like Figure 3 As shown, the ball-grabbing mechanism 3 includes two ball-grabbing plates 6 that rotate in opposite directions and at the same speed. A ball-grabbing drive unit 10 can be provided on the back of the ball-grabbing plate 6, which can rotate synchronously with the motor. The ball-grabbing plate 6 is driven by a motor; an obtuse-angled groove is formed on the inner side of the ball-grabbing plate 6; when grabbing the ball, the two ball-grabbing plates 6 rotate to the closest position, and the ball-grabbing plates 6 are in a horizontal state. Figure 3 In the state shown, the ball-grabbing plate 6 on the left rotates counterclockwise, while the ball-grabbing plate 6 on the right rotates clockwise.

[0037] To facilitate the production and replacement of the ball-gripping piece 6, it is preferable that the ball-gripping piece 6 is made of plastic or foam. The ball-gripping piece 6 does not need to have very high strength, so plastic or foam is sufficient. At the same time, plastic and foam are easy to process and obtain, and users can also cut them themselves for easy use.

[0038] like Figure 4 As shown, the serving mechanism 4 includes two counter-rotating serving wheels 12, which can rotate at the same speed or at different speeds. When the two serving wheels 12 rotate at the same speed, if the shuttlecock 11 falls between them, it will be hit in a parabolic trajectory towards the middle of the two serving wheels 12, resulting in a more centered serving direction. When the two serving wheels 12 rotate at different speeds, the shuttlecock will generally be hit towards the side of the faster-rotating serving wheel 12. Of course, the initial angle of the shuttlecock 11 as it falls through the catcher mechanism 3 may vary, so the landing point is not fixed. Consequently, the angle at which the shuttlecock 11 is hit will be different each time, making it suitable for users to simulate actual matches. The motors of the serving mechanism 4 and the catcher mechanism 3 can be equipped with gears or gear sets to drive the serving wheels 12 or the catcher plate 6. The left serving wheel 12 rotates clockwise, and the right serving wheel 12 rotates counter-clockwise.

[0039] It is worth mentioning that the 12-turn serve can be like Figure 4 As shown, it can be placed horizontally or tilted upwards to give the ball a certain initial angle when serving.

[0040] like Figure 4 As shown, the serving mechanism 4 also includes a tray 8 disposed at the bottom of the serving wheel 12. The tray 8 is fixedly installed on the back plate 1 and can be used as follows: Figure 4 The L-shaped fixing part shown on the back is used for fixing. The tray 8 is equipped with a motor for driving the ball-serving wheel 12 to rotate, which can be controlled by a PLC controller.

[0041] Continue to refer to Figure 4The service wheel 12 includes an inner rotating roller and an outer rubber sleeve. The rubber sleeve has protrusions, and the rotating roller has grooves. When the rubber sleeve is installed, the protrusions and grooves fit together. Through the contact between the rubber sleeve and the shuttlecock 11, good friction can be ensured between the shuttlecock 11 and the service wheel 12, thereby facilitating the serve.

[0042] Baffles 9 can be installed at both ends of the tray 8 to prevent badminton shuttlecocks from flying out accidentally. A through groove 13 can also be made on the tray 8 directly opposite the shuttlecock tube; the through groove 13 can be referenced from [reference needed]. Figure 4 As shown, if the shuttlecock fails to be hit by the serving wheel 12, it can fall through the channel 13.

[0043] like Figure 6 , Figure 7 and Figure 8 As shown, a mounting base 15 is slidably mounted on the guide rail 5. The top of the mounting base 15 has an L-shaped mounting groove 16. The ball cylinder 2 has a mounting part 19, which fits the shape of the mounting part 19 and the mounting groove 16. During installation, the mounting part 19 is inserted into the mounting groove 16 from the top. Figure 6 and Figure 7 As shown, the shuttlecock tube 2 can be inserted from above the mounting slot 16. The shuttlecock tube 2 and the shuttlecock 11 are held on the mounting seat 15 by gravity. Obviously, when the shuttlecock grabbing mechanism 3 grabs the shuttlecock, the main force is downward and the upward force on the shuttlecock tube 2 is small. Therefore, this installation is stable enough.

[0044] It is worth mentioning that the ball-serving system based on PLC in this application can adopt a forward and reverse circuit; the speed control system can adopt a PWM pulse width speed regulation circuit, thereby controlling the speed and frequency of the badminton shuttlecock 11 launch; the badminton shuttlecock 11 serving machine proposed in this application is suitable for badminton players and beginners.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
