Description

Technical Field

[0001] This utility model relates to the field of table tennis ball detection technology, and in particular to an air-floating table tennis ball detection device. Background Technology

[0002] Table tennis, as China's national sport, has a wide influence in various competitions. With the continuous development of the sport and the constant improvement of competitive techniques, the quality requirements for table tennis pieces are also becoming increasingly higher.

[0003] Existing patent document CN219064430U discloses a machine vision-based air-floating ping-pong ball diameter and eccentricity detection device. By installing a feeding device, after the ping-pong ball is detected, the handle is moved left or right to slide the ping-pong ball from slide one to slide three. Returning the handle to its original position allows the ping-pong ball to slide from slide three to slide two, thus completing the feeding process. By installing a discharging device, after the ping-pong ball is detected, the handle is moved, causing a U-shaped bracket to move the discharging plate. This causes a baffle to block the airflow from the fan, causing the ping-pong ball to fall onto the discharging plate and then into a collection box, achieving the purpose of discharging the ping-pong ball.

[0004] Although the aforementioned machine vision-based air-floating ping-pong ball diameter and eccentricity detection device can solve the corresponding technical problems, it requires manual operation of the feeding and unloading devices for each detection. Manual operation is time-consuming and labor-intensive, and it is difficult to adjust the feeding speed of the ping-pong balls according to the subsequent detection speed.

[0005] Therefore, an air-floating ping-pong ball detection device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an air-floating ping-pong ball detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] An air-floating ping-pong ball detection device includes:

[0009] The shell has an internal cavity equipped with a detection mechanism for air-float detection of ping-pong balls, a feeding mechanism for automatically feeding the ping-pong balls to be tested on the top of the shell, and a feeding mechanism for sorting the tested ping-pong balls on the shell.

[0010] The feeding mechanism includes a ball box for storing ping-pong balls to be tested. A baffle is movably connected to the ball outlet of the ball box. An opening and closing device is provided between the baffle and the ball box. One side of the bottom of the ball box is rotatably connected to the top of the shell. An adjusting device that can adjust the tilt angle of the ball box is provided between the other side of the bottom of the ball box and the shell.

[0011] As a preferred technical solution, a feeding port for ping-pong balls to enter the shell is opened at the top of the shell and directly above the air flotation platform of the testing mechanism. A discharge port for ping-pong balls to exit the shell is opened on both sides of the shell. The two discharge ports are symmetrically arranged about the center of the air flotation platform of the testing mechanism. The ball outlet of the ball box is located above the feeding port.

[0012] As a preferred technical solution, the opening and closing component includes a bracket installed on the bottom of the ball box near the feed port, and a first electric push rod is installed on each of the two sides of the top of the bracket, with the output end of the first electric push rod being fixedly connected to the baffle.

[0013] As a preferred technical solution, the adjusting component includes a screw rotatably connected to the top of the housing, the surface of the screw being threaded with a threaded tube, and the top end of the threaded tube being movably connected to the side of the bottom of the ball box away from the feed port.

[0014] As a preferred technical solution, a sliding seat is rotatably connected to the top end of the solenoid, and a T-shaped strip is slidably connected to the inner cavity of the sliding seat. One side of the T-shaped strip is fixedly connected to the bottom of the ball box.

[0015] As a preferred technical solution, a knob is fixedly sleeved on the lower part of the screw surface, and the surface of the knob is provided with a vertically arranged protrusion.

[0016] As a preferred technical solution, the feeding mechanism includes a guide plate that is movably disposed through the inner cavity of the discharge port. The guide plate has grooves on both sides, and a slider is slidably connected to the inner cavity of the groove. One side of the slider is fixedly connected to the inner wall of the discharge port.

[0017] As a preferred technical solution, an L-shaped frame is fixedly connected to the surface of the guide plate, and a second electric push rod is installed on the top of the housing. The output end of the second electric push rod is fixedly connected to one end of the L-shaped frame.

[0018] This utility model has at least the following beneficial effects:

[0019] This application achieves automatic feeding and unloading of ping-pong balls by using an opening and closing mechanism to automatically raise and lower a baffle, and by using an L-shaped frame to automatically move a guide plate. This eliminates the need for manual operation, saving labor intensity and increasing the feeding and unloading rate of ping-pong balls, thereby further improving the detection rate. At the same time, the tilt angle of the ball box can be adjusted by an adjusting mechanism, which can control the speed of ball unloading. This allows for the selection of a suitable feeding speed based on the subsequent detection speed, thus improving the applicability of this air-floating ping-pong ball detection device.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-3This utility model provides an air-floating ping-pong ball detection device, including a housing 100, a detection mechanism 200 for air-floating detection of ping-pong balls, a feeding mechanism 300 for automatically feeding the ping-pong balls to be detected, and a discharging mechanism 400 for sorting the detected ping-pong balls. The detection mechanism 200 is installed in the inner cavity of the housing 100, the feeding mechanism 300 is located on the top of the housing 100, and the discharging mechanism 400 is located on the housing 100. The feeding mechanism 300 includes a ball box 310 for storing the ping-pong balls to be detected. A baffle 320 is movably connected to the ball outlet of the ball box 310. An opening and closing element is provided between the baffle 320 and the ball box 310. One side of the bottom of the ball box 310 is rotatably connected to the top of the housing 100 through a rotating shaft. An adjusting element 350 that can adjust the tilt angle of the ball box 310 is provided between the other side of the bottom of the ball box 310 and the housing 100.

[0026] It should be noted that the working principle of the aforementioned testing agency 200 is consistent with that of the machine vision-based air-floating ping-pong ball diameter and eccentricity detection device disclosed in the existing announcement number CN203687884U. It adopts machine vision technology, and a large amount of contour edge information on the ping-pong ball can be obtained from a single frame image. The data after comprehensive processing of multiple frames of images can more scientifically reflect the diameter and eccentricity of the ping-pong ball. It is existing technology, so it will not be described in detail in this technical solution.

[0027] The top of the housing 100, directly above the air flotation platform of the detection mechanism 200, has a feeding port 110 for ping-pong balls to enter the housing 100. On both sides of the housing 100, there is a discharge port 120 for ping-pong balls to exit the housing 100. The two discharge ports 120 are symmetrically arranged about the center of the air flotation platform of the detection mechanism 200. The ball outlet of the ball box 310 is located above the feeding port 110.

[0028] The opening and closing mechanism includes a bracket 330 installed at the bottom of the ball box 310 near the feed port 110. The bracket 330 has a first electric push rod 340 installed on both sides of its top. The output end of the first electric push rod 340 is fixedly connected to the baffle 320. By activating the first electric push rod 340, the output end of the first electric push rod 340 can drive the baffle 320 to move automatically up or down inside the ball box 310. This allows the ping-pong balls inside the ball box 310 to fall through the ball outlet of the ball box 310 and enter the housing 100 through the feed port 110, thereby achieving the effect of automatic feeding.

[0029] The adjusting component 350 includes a screw 351 rotatably connected to the top of the housing 100 via a bearing. A screw tube 352 is threaded onto the surface of the screw 351. The top end of the screw tube 352 is movably connected to the bottom of the ball box 310 away from the feed port 110. By rotating the screw 351, the screw tube 352 can be moved up and down under the action of the thread. This allows the top end of the screw tube 352 to push or pull one side of the ball box 310 to move synchronously, thereby changing the tilt angle of the ball box 310 and controlling the speed of the ball. This facilitates the selection of a suitable feeding speed based on the subsequent detection speed.

[0030] The top end of the solenoid 352 is rotatably connected to a sliding seat 353 via a rotating shaft. A T-shaped strip 354 is slidably connected to the inner cavity of the sliding seat 353. One side of the T-shaped strip 354 is fixedly connected to the bottom of the ball box 310. When the solenoid 352 moves up and down, it can drive the sliding seat 353 to slide on the surface of the T-shaped strip 354. This not only limits the movement of the solenoid 352, allowing it to move stably along the axis of the screw 351 and preventing it from rotating synchronously with the screw 351, but also enables the solenoid 352 to move in conjunction with the ball box 310. This allows the solenoid 352 to push or pull one side of the ball box 310 to move synchronously when it moves up and down, preventing the solenoid 352 from detaching from the ball box 310.

[0031] A knob 355 is fixedly sleeved on the lower part of the surface of the screw 351, which makes it convenient for the hand to rotate the screw 351. The surface of the knob 355 is provided with a vertically arranged protrusion, which can increase the friction between the hand and the screw 351 and play an anti-slip role.

[0032] The feeding mechanism 400 includes a guide plate 410 that is movably inserted through the inner cavity of the discharge port 120. The guide plate 410 is inclined so that the tested ping-pong balls can be smoothly discharged from the guide plate 410 into the housing 100. The guide plate 410 has grooves 420 on both sides. A slider is slidably connected to the inner cavity of the groove 420. One side of the slider is fixedly connected to the inner wall of the discharge port 120. By moving the guide plate 410 toward the inner cavity of the housing 100 to the maximum extent, the guide plate 410 can block the gas ejected from the air flotation platform of the detection mechanism 200, so that the suspended ping-pong balls can fall into the guide plate 410 for guidance and sorting, and the ping-pong balls can be classified into the outer receiving frame.

[0033] The guide plate 410 is fixedly connected to an L-shaped frame 430, and a second electric push rod 440 is installed on the top of the housing 100. The output end of the second electric push rod 440 is fixedly connected to one end of the L-shaped frame 430. By activating the second electric push rod 440, the L-shaped frame 430 and the guide plate 410 can be automatically moved within the discharge port 120 through the output end of the second electric push rod 440. This allows the ping-pong balls to be automatically sorted into the outer receiving frame without the need for manual sorting, saving labor costs and improving sorting efficiency and accuracy.

[0034] The working principle of this utility model is as follows: A large number of ping-pong balls to be tested are placed in the ball box 310 for storage. By rotating the screw 351 through the knob 355, the screw 351 drives the screw tube 352 to move up or down on the surface of the screw 351. The top of the screw tube 352 pushes or pulls the sliding seat 353, causing the sliding seat 353 to move on the surface of the T-shaped strip 354. The T-shaped strip 354 and one side of the ball box 310 move synchronously with the sliding seat 353, so that the ball box 310 rotates with the shell 100. The shaft rotates around its axis to change the tilt angle of the ball box 310, allowing the selection of a suitable feeding speed based on the subsequent detection speed. During detection, the detection mechanism 200 and the first electric push rod 340 are activated. The output end of the first electric push rod 340 drives the baffle 320 to move upward within the inner cavity of the ball box 310, creating a gap between the bottom of the baffle 320 and the ball outlet of the ball box 310. This gap continues until its height matches the diameter of the ping-pong ball. At this point, the ping-pong ball passes through the gap and the feeding port 110 sequentially, falling into the housing 100. The ping-pong ball is measured while suspended by the detection mechanism 200. When the ping-pong ball passes the test, one of the second electric push rods 440 is activated. The output end of the second electric push rod 440 drives the L-shaped frame 430 and the guide plate 410 to move within the discharge port 120. This causes the slider to slide within the inner cavity of the chute 420. The guide plate 410 gradually moves into the inner cavity of the housing 100 until it reaches its maximum extent. This causes the guide plate 410 to block the gas ejected from the air flotation platform of the detection mechanism 200, thereby... Qualified suspended ping-pong balls can fall into the guide plate 410 for guidance and sorting, so that the ping-pong balls can be automatically classified into the outer receiving frame. When the ping-pong ball fails the test, another second electric push rod 440 is activated, which ultimately causes the corresponding guide plate 410 to block the gas ejected from the air flotation platform of the detection mechanism 200, so that the unqualified suspended ping-pong ball can fall into the guide plate 410 for guidance and sorting, so as to realize the automatic guidance and sorting operation and complete the detection operation of ping-pong balls.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model 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 this utility model, the scope of which is defined by the appended claims and their equivalents.
