[0022] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

An aggregate box 6 is provided at the bottom end of the workbench 1, and the aggregate box 6 is correspondingly arranged below the positioning assembly 3.

[0024] Specifically, as Figure 2 shown, the ball guiding assembly includes a support 204, a ball guiding channel 201 and a flipping drive. The ball guiding channel 201 is rotatably connected to the top end of the support 204. One end of the ball guiding channel 201 has an opening. The flipping drive is connected to the ball guiding channel 201. The flipping drive includes a flipping cylinder 203 and a rotating shaft 202. The rotating shaft 202 is fixed to the bottom end of the ball guiding channel 201. Both ends of the rotating shaft 202 are respectively rotatably connected to the support 204 through bearings. The bottom end of the flipping cylinder 203 is rotatably connected to the support 204, and the top end is rotatably connected to the bottom end of the ball guiding channel 201;

[0025] The positioning assembly includes a ball guiding seat 301, a positioning roller 303 and a positioning roller drive capable of driving the positioning roller 303 to rotate and translate. The ball guiding seat 301 is correspondingly arranged below the opening of the ball guiding channel 201. The ball guiding seat 301 has a plurality of ball guiding grooves capable of receiving the balls dropped from the opening of the ball guiding channel 201. The positioning roller 303 has annular positioning grooves corresponding to the ball guiding grooves one by one and capable of receiving partial embedding of the balls. The positioning roller drive includes a pushing cylinder 306, a positioning guide rail 305, a positioning seat 304 and a positioning roller motor 302. The positioning seat 304 is slidably connected to the positioning guide rail 305. The positioning roller 303 is rotatably connected to the top end of the positioning seat 304. The pushing cylinder 306 can drive the positioning seat 304 to move horizontally along the positioning guide rail 305. The positioning roller motor 302 can drive the positioning roller 303 to rotate axially through a chain;

[0026] The commutation component includes a commutation pulley set and a pulley drive capable of driving the commutation pulley set to transmit. The pulley drive uses a servo motor 401. The commutation pulley set includes a set of pulleys 402 and a transmission belt 403. The transmission belt 403 is correspondingly arranged below the positioning roller 303. The commutation pulley set is inclined towards the direction close to the positioning roller 303. The transmission belt 403 can support the bottom end of the ball and prevent the ball from falling off the transmission belt 403. The running direction of the commutation pulley set is perpendicular to the running direction of the positioning roller 303. The servo motor 401 can drive the commutation pulley set to operate, driving the balls in the positioning roller 303 to roll and commutate;

[0027] Combined with Figure 3 As shown, the polishing component includes a polishing roller 502 and a polishing roller drive capable of driving the polishing roller 502 to rotate and translate. The polishing roller 502 is arranged opposite to the positioning roller 303. The polishing roller drive includes a servo motor 503, a ball screw 504, a slide rail 507, a slide seat 506 and a polishing roller motor 501. The slide seat 506 is slidably connected to the slide rail 507. The polishing roller 502 is rotatably connected to the top end of the slide seat 506. The servo motor 503 is connected to the slide seat 506 through a belt 505 and a ball screw 504. The servo motor 503 can drive the slide seat 506 to slide along the slide rail 507. The polishing roller motor 501 is fixed to the top end of the slide seat 506, and the polishing roller motor 501 can drive the polishing roller 502 to rotate.

[0028] During processing, the operator places spherical balls (such as billiard balls) into the ball box, and the elevator sends the spherical balls into the ball guiding channel 201 one by one. The pushing cylinder 306 drives the positioning seat 304 to move horizontally forward along the positioning guide rail 305, so that the positioning roller 303 approaches the belt pulley group for position change. At this time, the flipping cylinder 203 drives the ball guiding channel 201 to flip downward, so that multiple spherical balls at the open end of the ball guiding channel 201 fall into the ball guiding grooves of the ball guiding seat 301, and then fall into the respective annular positioning grooves of the positioning roller 303 through the ball guiding grooves. The bottom of the spherical ball is supported by the conveyor belt 403 of the belt pulley group for position change. Since the belt pulley group for position change is inclined towards the positioning roller 303, the rear end of the spherical ball is embedded in the annular positioning groove and will not fall out of the annular positioning groove, completing the blanking; then, the positioning roller motor 302 drives the positioning roller 303 to rotate axially through a chain, and the spherical ball rotates in the reverse direction along with the positioning roller 303. At the same time, the servo motor 503 drives the slide seat 506 to slide forward along the slide rail 507, so that the polishing roller 502 abuts against the front end of the spherical ball. The polishing roller motor 501 drives the polishing roller 502 to rotate, and then the surface of the spherical ball can be polished; since the spherical ball is always rotated and polished in the X direction (the rotation direction of the positioning roller 303 or the polishing roller 502), in order to ensure the uniformity of polishing, it is necessary to change its position. After one direction of the spherical ball is polished, the polishing roller 502 retracts, and the servo motor 401 drives the belt pulley group for position change to operate a certain distance, driving the spherical ball in the positioning roller 303 to roll and change position in the Y direction (the transmission direction of the belt pulley group for position change). Due to the limitation of the annular positioning groove, the spherical ball will not move in the Y direction. After the position change is completed, the polishing roller 502 continues to polish the spherical ball after the position change. After multiple position changes, the all-round uniform polishing of the spherical ball can be completed; after the polishing is completed, the polishing roller 502 and the positioning roller 303 retract. Since the spherical ball is no longer limited, the spherical ball falls off the belt pulley group for position change and enters the aggregate box 6 for collection.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
