At this time, the detection electric push rod 801 is controlled to extend so that the sensor element 802 at the top of the telescopic rod of the detection electric push rod 801 gradually approaches and contacts the table tennis body 10. A total of 8 evenly distributed positions are used to detect the surface hardness of the table tennis body 10 at the same time, and the detection result is more accurate. After the detection is completed, the internal chip of the sensor element 802 is separated. The hardness is analyzed and judged whether it is qualified. If the hardness is qualified, the rotating motor 309 near the first ball falling groove 101 controls the rotating frame 4 on this side to rotate along the direction of the first ball falling groove 101, and controls the small vacuum pump to make the side air pipe 408 on the other side blow air, so that the qualified table tennis ball body 10 is blown out of the first ball falling groove 101. If the hardness is unqualified or the surface hardness is extremely uneven, the rotating frame 4 near the second ball falling groove 102 is controlled to rotate, and the unqualified table tennis ball body 10 falls from the second ball falling groove 102. Multiple placement racks 3 can detect multiple table tennis balls at one time.

[0056] The two side small push rods 407 are controlled to contract so that the distance between the two side suction cups 401 is close, and the front and rear positions of the table tennis body 10 can be initially clamped. The side air pipes 408 are evacuated to form negative pressure, and the side suction cups 401 can be used to fix the table tennis body 10 more firmly. The side steering gears 404 can be driven to realize the side suction cups 401 to rotate to an appropriate angle, and the table tennis body 10 can be controlled to rotate in one direction. After the double-headed motor 501 is driven to make the clamping suction cups 504 clamp and negatively pressure the fixed column table tennis body 10, the driving steering gear 506 is started to control the clamping suction cups 504 to rotate, and the table tennis body 10 can be controlled to rotate in another direction. The top small push rod 607 and the bottom small push rod 307 are contracted, respectively, so that the top suction cup 601 and the bottom suction cup 301 are close to and contact the table tennis body 10, and the top air pipes 608 and the bottom air pipes 308 are evacuated to form negative pressure to firmly clamp, and the top steering gear 604 and the bottom steering gear 306 are driven. 04 can control the table tennis body 10 to rotate with one more degree of freedom. The table tennis body 10 can rotate in three mutually perpendicular planes. By using multiple suction cups, the position of the table tennis body 10 can be freely rotated. After the table tennis body 10 falls on the top of the placement rack 3 according to the predetermined trajectory, the intelligent camera 9 can just see the surface of the table tennis body 10, and the joint position of the table tennis body 10 can be simply found. The joint position of the table tennis body 10 is rotated to the position of the placement rack 3 and the rotating rack 4. The position where the sensor element 802 contacts the table tennis body 10 is all non-joint, and the detection is more accurate. The slight collision after contact can cause a slight deformation of the spherical surface of the table tennis body 10. The pressure sensor 11 installed on the inner surface of the placement rack 3 and the rotating rack 4 can detect the pressure change in time. The internal chip of the pressure sensor 11 can simply analyze whether the force at the joint of the table tennis body 10 is uniform and whether the quality is qualified.
