Technical Field

[0001] This utility model relates to the field of ping-pong ball surface dent detection technology, specifically a low-cost device for detecting ping-pong ball surface dents. Background Technology

[0002] Table tennis is a sport with low requirements and high accessibility. It can be played by people of all ages and genders, across the country, indoors or outdoors, and regardless of financial means. Those with better resources can play on high-end tables, while those with less resources can play on simple cement tables, or even by piecing together several tables. In good weather, it can be played outdoors, and in strong winds or heavy snow, it can be played in a small room. Table tennis is also a full-body exercise, beneficial for physical, mental, and psychological well-being. Compared to sports like football and basketball, it doesn't involve direct physical contact, and the intensity can be controlled, making it very easy to popularize. In short, this sport is particularly suitable for China's national conditions, enjoys widespread popularity, and has a high degree of popularity among the Chinese people.

[0003] Currently, the wear and tear on ping-pong balls is very high. After ping-pong balls are produced, they need to undergo dent testing. Unqualified ping-pong balls cannot be sold. Existing tests for resistance to deformation often use various sensors to detect dents in ping-pong balls. However, due to the high precision of the sensors, the purchase cost of ordinary testing devices is very high.

[0004] Therefore, a low-cost device for detecting surface dents on ping-pong balls is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a low-cost device for detecting surface dents in ping-pong balls, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a base, wherein a detection mechanism is assembled on the top of the base; The detection mechanism includes a ball frame, a ball-dispensing plate, a first channel, a rotating rod, a ball-dispensing wheel, an electric slide rail, a second motor, a triangular gripper, and an intelligent vision sensor. The ball frame is fixedly connected to the top of the base. The ball-dispensing plate is rotatably connected to the bottom of the inner wall of the ball frame via a bearing. The upper surface of the first channel is fixedly connected to the lower surface of the ball frame. The rotating rod is rotatably connected to the side of the inner wall of the first channel via a bearing. The ball-dispensing wheel is fixedly sleeved on the outer wall of the arc-shaped surface of the rotating rod. The lower surface of the electric slide rail is fixedly connected to the upper surface of the base. The second motor is fixedly connected to the upper surface of the electric slide rail. The triangular gripper is fixedly connected to the side of the output end of the second motor. The intelligent vision sensor is fixedly connected to the back of the first channel. A sorting assembly is mounted on the top of the base.

[0007] Preferably, the sorting assembly includes a good ball box, a second channel, and a bad ball box. The good ball box is fixedly connected to the upper surface of the first channel, the second channel is fixedly connected to the side of the first channel, and the bad ball box is fixedly connected to the top of the first channel.

[0008] Preferably, the first channel is U-shaped, with the ball inlet of the first channel located at the bottom of the ball frame and the ball outlet of the first channel located at the bottom of the good ball box.

[0009] Preferably, a first motor is fixedly connected to the side of the first channel, the rotating rod moves through the first channel, the extension end of the rotating rod extends to the side of the first channel, and the extension end of the rotating rod is fixedly connected to the output end of the first motor.

[0010] Preferably, the first channel has a first window on its side for sliding between the output end of the second motor and the triangular gripper.

[0011] Preferably, a second window is provided on the back of the first channel for the intelligent vision sensor to detect the dent in the ping-pong ball.

[0012] Preferably, a capacitive proximity sensor for monitoring the approach of a ping-pong ball is fixedly connected to the side of the triangular gripper, and the capacitive proximity sensor is electrically connected to the electric slide rail.

[0013] Compared with the prior art, this utility model provides a low-cost device for detecting surface dents on ping-pong balls, which has the following beneficial effects: First, the combination of the ball-dispensing plate and the ball-dispensing wheel can continuously transport ping-pong balls from the ball frame to the detection channel. The electric motor drives the ball-dispensing plate to rotate, so that the ping-pong balls can fall orderly from the through hole at the bottom of the ball frame into the first channel. Moreover, after the detection is completed, whether the balls are good or bad, they can be quickly sorted by the corresponding mechanism.

[0014] Second, although intelligent vision sensors are used in the critical dent detection process, through reasonable device design, they can be reused for the detection of each ping-pong ball, instead of requiring multiple high-precision sensors to detect multiple ping-pong balls simultaneously, as some traditional detection devices may require multiple high-precision sensors, thus reducing the overall number and cost of sensors used.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] See Figures 1-5 This embodiment provides a low-cost device for detecting surface dents on ping-pong balls, including a base 1, with a detection mechanism 2 mounted on the top of the base 1; The detection mechanism 2 includes a ball frame 21, a ball-dispensing plate 22, a first channel 23, a rotating rod 24, a ball-dispensing wheel 25, an electric slide rail 26, a second motor 27, a triangular gripper 28, and an intelligent vision sensor 29. The ball frame 21 is fixedly connected to the top of the base 1. The ball-dispensing plate 22 is rotatably connected to the bottom of the inner wall of the ball frame 21 via a bearing. The upper surface of the first channel 23 is fixedly connected to the lower surface of the ball frame 21. The rotating rod 24 is rotatably connected to the side of the inner wall of the first channel 23 via a bearing. The ball-dispensing wheel 25 is fixedly sleeved on the outer wall of the arc-shaped surface of the rotating rod 24. The lower surface of the electric slide rail 26 is fixedly connected to the upper surface of the base 1. The second motor 27 is fixedly connected to the upper surface of the electric slide rail 26. The triangular gripper 28 is fixedly connected to the side of the output end of the second motor 27. The intelligent vision sensor 29 is fixedly connected to the back of the first channel 23. A sorting assembly is mounted on the top of the base 1.

[0019] The bottom output end of the ball-dispensing plate 22 is connected to an external electric motor. The electric motor drives the ball-dispensing plate 22 to rotate. During the rotation of the ball-dispensing plate 22, the ping-pong ball falls from the through hole at the bottom of the ball frame 21 into the first channel 23. The first motor 241 is started, and the first motor 241 drives the rotating rod 24 to rotate. The rotating rod 24 drives the ball-dispensing wheel 25 to rotate. When the ball-dispensing wheel 25 is moving fast, it sends the ping-pong ball to the top of the first channel 23. When it passes the capacitive proximity sensor, the capacitive proximity sensor drives the electric slide rail 26 to move to the left. The electric slide rail 26 drives the second motor 27 to move to the left. The second motor 27 drives the triangular gripper 28 to rotate. The triangular gripper 28 drives the ping-pong ball to rotate. The indentation of the ping-pong ball is detected by the intelligent vision sensor 29.

[0020] See Figures 2-5 The sorting assembly includes a good ball box 210, a second channel 211, and a bad ball box 212. The good ball box 210 is fixedly connected to the upper surface of the first channel 23, the second channel 211 is fixedly connected to the side of the first channel 23, and the bad ball box 212 is fixedly connected to the top of the first channel 23.

[0021] When a good ball is encountered, the electric slide rail 26 drives the second motor 27 to move to the right. The second motor 27 drives the triangular gripper 28 to move to the right. When the electric slide rail 26 moves to the right, the capacitive proximity sensor is turned off, and the triangular gripper 28 releases its grip on the ping-pong ball. The ping-pong ball falls naturally and lands on the outer wall of the ball-release wheel 25. The first motor 241 is then activated again. The first motor 241 drives the rotating rod 24 to rotate, which in turn drives the ball-release wheel 25 to rotate, moving the ping-pong ball upwards. At this point, the ball finally lands inside the good ball box 210, where it is then released by the motor. The plate 22 rotates, so that the ball-dealing plate 22 no longer blocks the through hole in the inner wall of the good ball box 210. When the intelligent vision sensor 29 detects a bad ball, the right electric slide rail 26 drives the second motor 27 and the triangular gripper 28 to move to the left, and the left electric slide rail 26 drives the second motor 27 and the triangular gripper 28 to move to the left, so that the ping-pong ball moves to the left as a whole. Then the right electric slide rail 26 drives the second motor 27 and the triangular gripper 28 to move to the right, releasing the grip on the ping-pong ball. The bad ball falls into the bad ball box 212 through the second channel 211.

[0022] The first channel 23 is U-shaped. The ball inlet of the first channel 23 is located at the bottom of the ball frame 21, and the ball outlet of the first channel 23 is located at the bottom of the good ball box 210.

[0023] A first motor 241 is fixedly connected to the side of the first channel 23. A rotating rod 24 movably passes through the first channel 23. The extended end of the rotating rod 24 extends to the side of the first channel 23 and is fixedly connected to the output end of the first motor 241.

[0024] The first channel 23 has a first window on its side for sliding the output end of the second motor 27 and the triangular gripper 28.

[0025] The back of the first channel 23 has a second window 291 for the intelligent vision sensor 29 to detect dents in the ping-pong ball.

[0026] A capacitive proximity sensor for monitoring the approach of a ping-pong ball is fixedly connected to the side of the triangular gripper 28. The capacitive proximity sensor is electrically connected to the electric slide rail 26.

[0027] The electric slide rail 26 is a ball screw, model Leadshine EC30; the intelligent vision sensor 29 is model Cognex In-Sight 7000; and the capacitive proximity sensor is model SICK CQ18-08GS04.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
