[0023] The implementation principle of the ball hole trepanning device for the injection molded part of the ball storage barrel of the tennis machine is as follows:

[0024] The manipulator absorbs the ball storage bucket injection molded parts and places them on the support 31 in the placement mechanism of the loading area.

The rotating cylinder 52 in the limit assembly 5 drives the baffle 53 to flip to the horizontal position. The lifting cylinder 41 in the lifting and rotating mechanism 4 drives the servo motor 43 to move upward, so that the turntable 44 rests on the bottom of the support column 311 of the support 31. The servo motor 43 works to drive the support 31 to rotate. Under the gravity of the ball storage bucket injection molded parts, the ball storage bucket injection molded parts are rotated to the positioning area. The rotating cylinder 52 in the limit assembly 5 drives the baffle 53 to flip to the horizontal position.
