Description

Technical Field

[0001] The invention belongs to the field of badminton training devices, in particular to a badminton supply device. Background Art

[0002] The supply device of a badminton serving machine is one of its core components, responsible for stably and efficiently delivering badmintons to the launching system. In an automated badminton serving machine, the badminton supply device is usually designed separately from the serving mechanism. The supply device is mainly responsible for storing, arranging, and delivering badmintons to the serving position. In the supply device, the badmintons are mostly stacked in an orderly manner in a silo through a vibrating plate. In order to prevent broken badmintons from being delivered to the serving position for launch, the badminton supply device needs to remove broken badmintons.

[0003] A patent document with announcement number CN222087356U discloses an automatic quality inspection device for badminton. When the badminton is launched into the test area by an external transmitter, the flight trajectory and flight speed of the badminton are captured in real time through a visual sensor. AI is used to analyze its flight speed and landing point, as well as whether the flight is smooth, to determine whether it meets the factory standards. The badminton is then hit to different positions by a racket for identification.

[0004] The above technical solution still has some problems in practical application. During badminton training, the head and feathers of the badminton shuttlecock can easily break when they collide with the racket or the ground. Frequent or high-intensity training will accelerate the breakage if these broken shuttlecocks are not removed. In addition, when badminton shuttlecocks are stacked in a silo, two shuttlecocks may overlap. During subsequent serves, the damaged or overlapping shuttlecocks will affect the serve trajectory, thereby interfering with training. The above technical solution can detect whether a badminton is damaged to a certain extent. However, while a damaged feather will inevitably affect the flight trajectory, a damaged head does not necessarily affect the trajectory. It is difficult to determine whether the head is damaged, and it does not solve the problem of overlapping shuttlecocks. Therefore, its detection effect is limited.

[0005] To this end, the present invention provides a badminton supply device. Summary of the Invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1

[0036] like Figure 1-6 As shown, a badminton supply device according to an embodiment of the present invention includes a housing 1, wherein a vibration plate 2 and a first silo 3 are provided in the housing 1. The vibration plate 2 is used to transport the badmintons to the first silo 3 for stacking. The device also includes a rejection mechanism 4 and a control system. The control system is used to control the rejection mechanism 4.

[0037] The rejecting mechanism 4 includes: a recycling box 41 provided in the housing 1; a rotating member 42 rotatably provided inside the recycling box 41, the rotating member 42 being located below the first silo 3; a support ring 421 provided on the rotating member 42 for supporting badmintons; a clamping assembly 43 movably provided in the rotating member 42, the clamping assembly 43 including a plurality of clamping rods 431 slidably provided in the rotating member 42, wherein the badmintons in the first silo 3 fall onto the support ring 421, and the clamping rods 431 move inward to squeeze and clamp the heads of the badmintons; a displacement detection assembly 44 for detecting the displacement of the clamping rods 431; a striking member 45 provided in the recycling box 41; and a second silo 46 provided in the recycling box 41, the second silo 46 being used to transport the badmintons to the serving position in the serving machine.

[0038] After the clamping assembly 43 releases the badminton, the striking member 45 strikes the badminton, and normal badmintons are knocked away and fall into the second silo 46 , while abnormal badmintons fall into the recovery box 41 .

[0039] Specifically, in this embodiment, the badminton supply device is installed on a badminton serving machine for use. The first silo 3 and the second silo 46 can adopt the badminton silo structure in the existing badminton serving machine. The badminton is distributed longitudinally in the silo with the ball head facing downward. One or more second silos 46 can be provided. Multiple second silos 46 are installed on a turntable. The first silo 3 and the second silo 46 are both provided with a sequential unloading mechanism. The bottom ends of the shell 1 and the recovery box 41 are both provided with a ball outlet. The displacement detection component 44 can adopt a displacement sensor. The movement of the clamping rod 431 toward the center of the rotating part 42 is inward movement, and vice versa is outward movement.

[0040] After hitting a badminton with a fixed force and a fixed angle, a normal badminton with an intact head and feathers will have a stable parabolic symmetry in its flight trajectory, a consistent rotation axis, and a concentrated landing point. An abnormal badminton with a cracked head or damaged feathers may have a trajectory deviation. Therefore, the flight trajectory or landing point of the badminton can be detected to determine whether it is normal.

[0041] When in use, the badmintons on the training ground are collected and placed in the vibration plate 2, and the vibration plate 2 is started to perform preliminary sorting of the badmintons, so that the badmintons fall into the first silo 3 in an orderly manner with the ball heads facing downwards. Initially, the rotating member 42 is in a horizontal state, and the clamping rod 431 is in an outward state. The badmintons in the first silo 3 fall downwards in turn and rest on the support ring 421. At this time, the ball heads are located on the horizontal plane where the clamping rod 431 is located. The clamping rod 431 is started to move inward to squeeze and clamp the ball heads. The displacement detection component 44 detects the inward movement of the clamping rod 431 to determine whether the ball heads are damaged. Taking a natural cork head as an example, the allowable compression displacement of a normal head under pressure is 1-2 mm. If the displacement exceeds 3 mm, it is determined to be damaged. Then, the rotating member 42 is started to rotate rapidly at a set fixed angle so that the badminton head is aligned with the striking member 45. During the rotation of the rotating member 42, if there are overlapping badmintons, the overlapping badmintons are thrown out and separated, thereby realizing the function of automatically removing the overlapping badmintons. In addition, for badmintons with damaged heads, the clamping rod 431 releases the head. During the rotation of the rotating member 42, the damaged badminton will be thrown out, thereby realizing the removal of damaged badmintons.

[0042] After the rotating member 42 stops, the striking member 45 is started to hit the badminton with a fixed force; if the badminton is normal and the flight trajectory of the badminton is within the normal range, the badminton will fall into the second silo 46 for storage. On the contrary, the abnormal badminton will fall outside the second silo 46 and fall into the recycling box 41, and the abnormal badminton will be collected separately by the recycling box 41. In this way, the function of automatically identifying and removing abnormal badmintons such as broken and overlapped ones is realized, thereby improving the success rate of the badmintons delivered to the serving position.

[0043] like Figure 6 As shown, a through groove is provided inside the rotating member 42, and the support ring 421 includes an upper and lower layer for supporting the feather and the ball head respectively. The lower support ring 421 is located in the through groove, and the clamping assembly 43 is staggered with the support ring 421.

[0044] Specifically, when the badminton rests on the support ring 421, the ball head is located in the through groove; the striking member 45 moves to the upper left and contacts the ball head in the through groove, thereby realizing the hitting action. Before hitting the ball, the rotating member 42 is in a tilted state. By providing a double-layer support ring 421, the badminton can also rest stably on the support ring 421 when it is tilted.

[0045] like Figure 4-5 As shown, the rejection mechanism 4 also includes an adjustment member 47 and a partition 48 provided in the recovery box 41. The adjustment member 47 is used to adjust the trajectory of the badminton knocked away by the striking member 45 so that the badminton moves toward the bottom opening of the second silo 46. The partition 48 is located below the rotating member 42 and is used to collect the badminton that falls from the rotating member 42.

[0046] Specifically, the adjusting member 47 is preferably, but not limited to, a racket structure. The adjusting member 47 is located at the upper left of the rotating member 42 and at the left side of the first silo 3. The second silo 46 is located below the adjusting member 47. After the striking member 45 moves to the upper left, it knocks the badminton in the rotating member 42 into flight. After the badminton flies out, it collides with the adjusting member 47 and changes its flight trajectory, and then falls downward. By providing the adjusting member 47, the area between the left side of the first silo 3 and the top of the second silo 46 can be fully utilized, thereby improving the problem of space being occupied in vain. Moreover, if the badminton becomes abnormal, the double striking effect of the striking member 45 and the adjusting member 47 on the badminton can further amplify the deviation of the badminton's flight trajectory, further ensuring that the abnormal badminton will not fall into the second silo 46.

[0047] During the rapid rotation of the rotating member 42 , the stacked badmintons are thrown out and fall onto the partition 48 to be separated from other damaged badmintons in the recycling box 41 .

[0048] Example 2

[0049] like Figure 4-9 As shown, compared with Example 1, another embodiment of the present invention is: it also includes a driving mechanism 5, the driving mechanism 5 includes: a driving gear 51 rotatably provided in the housing 1, the driving gear 51 is provided with two tooth segments; a driven gear 52 provided on the rotating member 42, during the rotation of the driving gear 51, the rotating member 42 is driven to rotate intermittently through the engagement of the two tooth segments with the driven gear 52.

[0050] Specifically, a damping member is provided on the rotating shaft of the rotating member 42. Initially, the rotating member 42 maintains a horizontal static state under the action of the damping. Figure 5In the embodiment, after the driving gear 51 is started to rotate counterclockwise, the tooth segment on the driving gear 51 contacts the driven gear 52 and drives the rotating member 42 to rotate clockwise. After the tooth segment separates from the driven gear 52, the rotating member 42 stops.

[0051] like Figure 5-8 As shown, the driving mechanism 5 also includes: an energy storage spring 53 provided on the striking member 45; a pressure plate 54 fixedly connected to the striking member 45; a first shift plate 511 and a second shift plate 521 respectively provided on the driving gear 51 and the driven gear 52. During the rotation of the driving gear 51 and the driven gear 52, the first shift plate 511 and the second shift plate 521 sequentially contact the pressure plate 54 and push the pressure plate 54 away from the rotating member 42.

[0052] Specifically, the two ends of the energy storage spring 53 are connected to the striking member 45 and the shell 1 respectively. Initially, the striking member 45 remains in a fixed position and away from the rotating member 42 under the action of the energy storage spring 53, and does not interfere with the rotation; after the driving gear 51 rotates counterclockwise, the second dial plate 521 first contacts the pressure plate 54, pushing the striking member 45 to move to the lower right, and then the first dial plate 511 contacts the pressure plate 54 and the second dial plate 521 separates from the pressure plate 54, and the first dial plate 511 continues to push the striking member 45 downward. During this process, the energy storage spring 53 is compressed and stores energy. After the first dial plate 511 separates from the pressure plate 54, the energy storage spring 53 releases energy, pushing the striking member 45 to move quickly to the upper left and hit the badminton located in the rotating member 42.

[0053] like Figure 6-8 As shown, the driving mechanism 5 also includes: a positioning member 55 provided on the driven gear 52; a correction member 56 provided on the striking member 45, and the correction member 56 is provided with a positioning groove corresponding to the driving positioning member 55. When the striking member 45 moves away from the rotating member 42, the correction member 56 contacts the positioning member 55 to correct the angle of the rotating member 42.

[0054] Specifically, in the driven gear 52, the side closer to the axis of the driven gear 52 in the radial direction is the inner side, and the opposite side is the outer side. The positioning member 55 is located at the outer end of the driven gear 52. Initially, the correction member 56 is located between the positioning member 55 and the axis of the driven gear 52. At this time, the driven gear 52 rotates, and the correction member 56 does not contact the positioning member 55.

[0055] When striking member 45 strikes the badminton, driving gear 51 and driven gear 52 are disengaged. As rotating member 42 continues to rotate due to inertia until it approaches the set angle, striking member 45 moves downward and rightward, driving correction member 56. Correction member 56 then contacts positioning member 55, adjusting the angle of rotating member 42 and ensuring that the head of the badminton in rotating member 42 is aligned with striking member 45. This automatically corrects the angle of rotating member 42, ensuring that the badminton in rotating member 42 is struck by striking member 45 at a fixed position, providing a stable initial condition for subsequent detection of the badminton's flight trajectory and landing point.

[0056] Example 3

[0057] like Figure 6-7 As shown, compared with Example 1, another embodiment of the present invention is: the clamping assembly 43 also includes: a magnetic block 432 slidably arranged at the end of the clamping rod 431; and a reset spring 433 for driving the clamping rod 431 to move outward and reset.

[0058] Specifically, initially, the clamping rod 431 is located inside the rotating member 42 under the action of the return spring 433 , and the clamping rod 431 does not extend into the through slot to avoid interfering with the badminton's resting on the support ring 421 .

[0059] like Figure 5-9 As shown, the driving mechanism 5 also includes: a magnetic conductive member 57 provided in the rotating member 42; a main magnet 58 provided on the driving gear 51. During the rotation of the driving gear 51, the main magnet 58 contacts the magnetic conductive member 57, magnetizes the magnetic conductive member 57, and repels the magnetic block 432, thereby pushing the clamping rod 431 inward.

[0060] Specifically, the main magnet 58 is arc-shaped, and the end of the magnetic member 57 extends to the outside of the rotating member 42. During the rotation of the driving gear 51, the main magnet 58 contacts the magnetic member 57 and magnetizes the magnetic member 57. After magnetization, the magnetic member 57 repels the magnetic block 432, thereby pushing the clamping rod 431 inward; after the main magnet 58 separates from the magnetic member 57, the magnetic member 57 loses its magnetism and moves outward and resets under the action of the reset spring 433.

[0061] like Figure 6-7 As shown, the displacement detection assembly 44 includes a plurality of push plates 441 provided in the rotating member 42. After the clamping rod 431 moves inward for too long, the push plates 441 contact the magnetic block 432 and push the magnetic block 432 upward to be offset from the magnetic conductive member 57.

[0062] Specifically, initially, the magnetic block 432 is located at the bottom of its moving range under the action of its own gravity and is horizontally aligned with the magnetic conductive member 57 .

[0063] When the rotating member 42 is in a horizontal state and the clamping rod 431 moves inward to squeeze and clamp the badminton head, if the head is normal, the inward movement of the clamping rod 431 is within the normal range, the magnetic block 432 does not contact the push plate 441, and then when the rotating member 42 rotates, the clamping rod 431 always clamps the head.

[0064] If the ball head is damaged, the inward movement of the clamping rod 431 exceeds the range, the magnetic block 432 contacts the push plate 441, and the push plate 441 pushes the magnetic block 432 to move upward until it is offset from the magnetic conductive member 57. The clamping rod 431 moves outward under the action of the reset spring 433, and then when the rotating member 42 rotates, the broken badminton is thrown out.

[0065] In this way, the function of automatically rejecting badmintons with damaged heads is realized. It should be noted that for badmintons of different material types, when the heads are normal, the inward movement stroke of the clamping rod 431 is different. By adjusting the position of the push plate 441, different types of badminton can be detected.

[0066] The device uses an elastic clamping rod 431 to detect the hardness of the shuttlecock head and determine whether the shuttlecock head is damaged. During the rotation of the rotating member 42, it cleans up the stacked shuttlecocks and shuttlecocks with damaged shuttlecock heads. The trajectory of the shuttlecock after being hit is used to screen out abnormal shuttlecocks. This can achieve efficient damage detection without over-reliance on electronic systems. This solution takes into account reliability (pure mechanical structure), low cost (no precision sensors) and high adaptability (compatible with multiple types of shuttlecocks). It is particularly suitable for scenarios that require large-scale processing, such as training venues, and reduces operating costs.

[0067] Example 4

[0068] like Figure 5 As shown, compared with Example 1, another embodiment of the present invention is: the rejection mechanism 4 also includes: a light detection unit 49 arranged in the recycling box 41, the light detection unit 49 is used to detect the transmittance of the badminton, and the light detection unit 49 includes a light source module and an image processing module respectively located on both sides of the badminton; a baffle 410 movably arranged in the shell 1, and the baffle 410 blocks the top of the second silo 46.

[0069] For more professional badminton training, the strike rate during serve is more stringent, and the accuracy of determining whether a badminton is abnormal needs to be further improved. Although damaged feathers in a badminton significantly affect the flight stability of the badminton, there is also a small probability that an abnormal badminton will fall into the second silo 46. Therefore, the light detection unit 49 and the baffle 410 are provided to improve this problem.

[0070] Specifically, the image processing module includes a high-speed camera and a data processor. After the light source module is activated, it evenly illuminates the badminton. The high-speed camera captures a transmission image of the badminton and sends the data to the data processor. Because the transmission images of the head and the badminton are significantly different, the transmission data of the head is filtered out and the transmission data of the feather is analyzed to obtain the transmission effect of the feather. This is then compared with a preset standard value. If the transmission effect of the feather meets the standard, the feather is considered normal; otherwise, the feather is considered damaged. Of course, the type of light source can also be changed to perform transmission detection on damaged heads.

[0071] If the badminton is determined to be normal, and the badminton falls after contacting the adjustment plate, the baffle 410 is opened, allowing the badminton to smoothly fall into the second silo 46. Otherwise, the baffle 410 is closed, preventing the badminton from falling into the second silo 46. This further improves the accuracy of determining whether the badminton is normal, and is suitable for professional-level badminton training.

[0072] Working principle: When in use, the badmintons from the training ground are collected and placed in the vibration plate 2. The vibration plate 2 is started to perform preliminary sorting of the badmintons, so that the badmintons fall into the first silo 3 in an orderly manner with the heads facing downwards. Initially, the rotating member 42 is in a horizontal state, the clamping rod 431 is in an outward state, and the badmintons in the first silo 3 fall downwards in sequence and rest on the support ring 421; at the same time, the driving gear 51 is started to rotate;

[0073] After the driving gear 51 rotates, the two tooth segments initially do not contact the driven gear 52, and the rotating member 42 remains horizontal and stationary. Then, the main magnet 58 on the driving gear 51 contacts the magnetic member 57, magnetizing the magnetic member 57. The magnetic member 57 then repel the magnetic block 432, thereby pushing the clamping rod 431 inward, squeezing and clamping the badminton head. After the driving gear 51 continues to rotate, the tooth segments come into contact and mesh with the driven gear 52, driving the rotating member 42 to rotate rapidly. During this process:

[0074] a. After the shuttlecock is clamped, if the shuttlecock is normal, the inward movement of the clamping rod 431 is within the normal range, the magnetic block 432 does not contact the push plate 441, and then when the rotating member 42 rotates, the clamping rod 431 always clamps the shuttlecock. The rapid rotation of the rotating member 42 will throw out other shuttlecocks stacked on the clamped shuttlecock, and the thrown shuttlecocks will fall on the partition 48;

[0075] b. After clamping the shuttlecock, if the shuttlecock is damaged, the inward movement of the clamping rod 431 exceeds the range, the magnetic block 432 contacts the push plate 441, and the push plate 441 pushes the magnetic block 432 upward until it is offset from the magnetic conductive member 57. The clamping rod 431 moves outward under the action of the return spring 433, releasing the shuttlecock. Then, when the rotating member 42 rotates, the damaged shuttlecock is thrown out.

[0076] The driving gear 51 and the rotating member 42 continue to rotate in opposite directions simultaneously, and the second shifting plate 521 first contacts the pressure plate 54, pushing the striking member 45 to move downward to the right.

[0077] After the driving gear 51 continues to rotate, the tooth segment separates from the driven gear 52. The rotating member 42 continues to rotate to a position close to the set angle under the action of inertia. The second shift plate 521 separates from the pressure plate 54. The first shift plate 511 contacts the pressure plate 54 and continues to push the striking member 45 downward. The energy storage spring 53 continues to be compressed and stores energy.

[0078] The striking member 45 moves to the lower right, driving the correction member 56 to move. After the correction member 56 moves, it contacts the positioning member 55, thereby adjusting the angle of the rotating member 42, ensuring that the rotating member 42 rotates to the set fixed angle and the ball head of the badminton in the rotating member 42 is aligned with the striking member 45. The function of automatically correcting the angle of the rotating member 42 is realized;

[0079] The driving gear 51 continues to rotate, and the main magnet 58 separates from the magnetic conductive member 57. The magnetic conductive member 57 loses its magnetism and, under the action of the return spring 433, moves outward and returns to its original position, releasing the shuttlecock. Then, the first paddle 511 separates from the pressure plate 54, and the energy storage spring 53 releases energy, pushing the striking member 45 to move rapidly upward and leftward, striking the shuttlecock in the rotating member 42. In this way, the striking member 45 strikes the shuttlecock in a fixed position with a constant force.

[0080] If the badminton is normal and its flight trajectory is within the normal range, the badminton will fall into the second silo 46 for storage. On the contrary, the abnormal badminton will fall outside the second silo 46 and fall into the recycling box 41. The recycling box 41 will collect the abnormal badminton separately. In this way, the function of automatically identifying and rejecting abnormal badmintons is realized, and the success rate of the badmintons delivered to the serving position is improved.

[0081] The driving gear 51 continues to rotate, and the other tooth segment contacts and separates from the driven gear 52, driving the rotating member 42 to rotate to the horizontal and then stop. The entire device returns to its initial state and can work in a cycle. By driving the driving gear 51 to rotate by the motor, automatic continuous operation can be achieved. Compared with the traditional method of setting up multiple groups of electric drive devices and intermittently starting the motor, the structure is simplified, the loss caused by frequent starting of the motor is reduced, and the service life is extended.
