[0049] The distance between the outer side surface of the rotating disk 13 and the inner wall of the base 1 is less than 20 mm.

[0050] The outer surface of the turntable 13 is provided with an arc-shaped clamping groove 16, which is connected to the outer side surface of the turntable 13 and to the upper and lower end surfaces of the turntable 13. The inner diameter of the clamping groove 16 is 5 mm to 8 mm larger than the outer diameter of the billiard ball 25. The distance of the side opening of the clamping groove 16 is 5 mm to 8 mm larger than the outer diameter of the billiard ball 25.

[0051] A camera groove 17 is also provided on the upper end surface of the turntable 13, and the camera groove 17 extends in a straight line direction. The bottom surface of the camera groove 17 is a planar structure, and the bottom surface of the camera groove 17 maintains a certain distance from the bottom end surface of the turntable 13. One end of the camera groove 17 along the straight extension direction is connected to the clamping groove 16, and the other end along the straight extension direction is connected to the outer side surface of the turntable 13.

The opening of the end of the camera groove 17 away from the clamping groove 16 gradually expands until it is connected to the outer side surface of the turntable 13. At the end of the camera groove 17 away from the clamping groove 16, an end ball blocking protrusion 18 is provided on the outer edge of its bottom surface.

[0052] The angle between the line connecting the ball inlet 2 and the first ball outlet 4 of the base 1 and the extending straight line of the camera groove 17 is 60° to 80°, preferably 70 degrees.

[0053] The outer surface of the base 1 is provided with an outwardly convex first camera fixing boss 21, and the first camera fixing boss 21 is provided with a cylindrical first camera fixing groove 29 inside, and the first camera fixing groove 29 is connected with the inside of the base 1. The first camera 22 is fixedly arranged inside the first camera fixing groove 29, and the lens of the first camera 22 faces the inner side of the base 1.

[0054] When the engaging groove 16 on the turntable 13 rotates to the upper side of the self-rotating disk 10, the end of the camera groove 17 on the turntable 13 away from the engaging groove 16 is opened at the first camera fixing groove 29, and the line between the first camera 22 and the self-rotating disk 10 is parallel to the extending direction of the camera groove 17. The first camera 22 can directly capture the image of the side of the billiard ball 25 through the camera groove 17.

[0055] The upper end surface of the fixed plate 7 is provided with an outwardly convex second camera fixing boss 23, and a conical second camera fixing groove 30 is provided inside the second camera fixing boss 23. The lower end outlet diameter of the second camera fixing groove 30 is larger than the upper end diameter, and the lower end outlet of the second camera fixing groove 30 is connected with the bottom end surface of the fixed plate 7. The axis of the second camera fixing groove 30 coincides with the axis of the rotating plate 10, and a downward second camera 24 is fixedly provided inside the second camera fixing groove 30, and the second camera 24 is located at the axis of the second camera fixing groove 30. The second camera 24 can directly capture the top image of the billiard ball 25.

[0056] The upper end surface of the rotating disk 13 is provided with an outwardly protruding position boss 19, and the lower end surface of the fixed disk 7 is fixedly provided with a proximity switch 26, and the distances between the position boss 19 and the proximity switch 26 and the axis of the base 1 are kept equal. When the position boss 19 on the rotating disk 13 rotates to below the proximity switch 26, the rotating disk 13 stops rotating.

[0057] On the bottom surface inside the base 1, the position at the goal entrance 2 is the goal position 27, the position at the first ball outlet 4 is the first ball outlet position 28, the position at the turntable 10 is the identification position, and the position at the second ball outlet 9 is the second ball outlet position. The heights of the identification position and the second ball outlet position are both higher than the height of the goal position 27, specifically 8mm to 12mm higher, and the identification position and the second ball outlet position are transitionally connected by a smooth slope surface. The height of the identification position is higher than the height of the first ball outlet position 28, specifically 8mm to 12mm higher, and the identification position and the first ball outlet position 28 are transitionally connected by a smooth slope surface.

[0058] The height of the goal position 27 is 1-3 mm lower than the lowest point of the goal opening 2 , and the height of the first ball outlet position 28 is 1-3 mm higher than the lowest point of the first ball outlet 4 .

[0059] The self-rotating motor 12 , the turntable motor 20 , the first camera 22 , the second camera 24 , and the proximity switch 26 are all connected to the processor.

[0060] The working principle of the present invention is:

[0061] First, the entire device is installed and fixed so that the entire device maintains a small inclination, and the height of the first ball outlet 4 is lower than the height of the ball inlet 2, so that the billiard ball 25 can roll freely inside the device due to gravity, and will not get stuck and stop rolling.

[0062] Then, the billiard balls 25 are sequentially passed through the billiard ball running pipeline 6 into the interior of the goal pipeline 3 and arranged in contact with each other. The turntable motor 20 drives the turntable 13 to rotate, and the clamping groove 16 of the turntable 13 corresponds to the goal opening 2, so that the billiard balls 25 at the front end enter the clamping groove 16, and the billiard balls 25 at the rear end are still located outside the goal opening 2.

[0063] The turntable motor 20 controls the turntable 13 to rotate, and the turntable 13 drives the billiard ball 25 to rotate toward the position of the identification position. When the position boss 19 corresponds to the proximity switch 26, the clamping groove 16 of the turntable 13 rotates to the upper part of the turntable 10, and the billiard ball 25 is located in the billiard ball fixing groove 11 above the turntable 10, and the turntable 13 stops rotating.

[0064] The first camera 22 and the second camera 24 respectively capture the images of the side and top of the billiard ball 25, and transmit the images to the processor, which identifies the color of the billiard ball 25. When the billiard ball 25 is identified as a white ball or a repeated ball, the processor controls the turntable motor 20 to rotate in the opposite direction, so that the turntable 13 drives the billiard ball 25 to rotate 180° in the opposite direction, so that it moves to the second ball outlet 9, so that the white ball or the repeated ball falls out of the second ball outlet 9. When the billiard ball 25 is identified as a colored ball, the processor controls the turntable motor 20 to continue to rotate forward, and the turntable 13 drives the billiard ball 25 to rotate to the first ball outlet 4, so that the colored ball is output from the first ball outlet 4.

[0065] When the images captured by the first camera 22 and the second camera 24 cannot be processed to obtain a specific pattern, the processor controls the rotation motor 12 to rotate, so that the turntable 10 drives the billiard ball 25 to rotate by a certain angle. After the billiard ball 25 rotates, the first camera 22 and the second camera 24 are used to capture the billiard ball 25 again until the pattern of the billiard ball 25 is finally obtained.

[0066] By providing a ball blocking protrusion 18 at the end opening of the camera groove 17 away from the clamping groove 16, the billiard balls 25 queued at the rear end can be blocked to a certain extent when the end opening passes through the ball hole 2, thereby improving the smoothness of the rotation of the turntable 13.

[0067] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
