[0027] A feed port 11 and a discharge port 13 are provided on the surface of the main disk 8, a feed pipe 12 is provided on the surface of the main disk 8 and on the side of the feed port 11, a discharge pipe 14 is provided on the surface of the main disk 8 and on the side of the discharge port 13, four material troughs 15 are evenly provided on the surface of the turntable 10, the material troughs 15 correspond to the feed port 11 and the discharge port 13, and motor magnetic tiles 16 are provided inside the material troughs 15. The motor magnetic tiles 16 can slide into the feed port 11 through the feed pipe 12. When the feed port 11 is in the same straight line with one of the material troughs 15, the motor magnetic tiles 16 can slide into the inside of the material trough 15. When the material trough 15 and the discharge port 13 are in the same straight line, the motor magnetic tiles 16 inside the material trough 15 slide into the discharge pipe 14 under the action of gravity, thereby realizing the discharge operation of the motor magnetic tiles 16.

[0028] By setting up the conveying mechanism 7, the motor magnetic tile 16 can slide into one of the material troughs 15 through the feed pipe 12 and the feed port 11, and the motor magnetic tile 16 can also slide out of the material trough 15 through the discharge port 13 and the discharge pipe 14. At the same time, through the cooperation of the grinding mechanism 29 and the conveying mechanism 7, the grinding mechanism 29 can grind the motor magnetic tile 16 in the material trough 15 opposite to the feed port 11 and the discharge port 13, thereby realizing assembly line operation, high efficiency and high output, reducing labor costs, and ensuring product consistency and quality.

[0029] A guide mechanism 22 is provided at the center of the main disk 8, and the guide mechanism 22 includes a first guide arc groove 23 and a second guide arc groove 24. The first guide arc groove 23 is close to the center of the main disk 8, and the second guide arc groove 24 is far away from the center of the main disk 8. Four movable grooves 17 are evenly arranged inside the turntable 10, and a clamping mechanism 18 is installed inside the movable groove 17. The clamping mechanism 18 includes an L-shaped clamping plate 19, and the surface of the L-shaped clamping plate 19 runs through the turntable 10. The surface above the L-shaped clamping plate 19 is close to the middle of the motor magnetic tile 16. A guide rod 20 is installed inside the movable groove 17, and the surface below the L-shaped clamping plate 19 is movably sleeved on the surface of the guide rod 20. A matching column 21 is fixedly installed at the bottom end of the L-shaped clamping plate 19, and the surface of the matching column 21 is movably installed on the guide rod 20. In the mechanism 22, it is movably installed inside the guide mechanism 22 through the matching column 21. Since the first guide arc groove 23 is close to the center of the main disk 8, and the first guide arc groove 23 is close to the feed port 11 and the discharge port 13, when the matching column 21 moves to the inside of the first guide arc groove 23, the upper surface of the L-shaped clamp 19 is completely retracted to the inside of the movable groove 17, and the L-shaped clamp 19 has no positioning effect on the motor magnetic tile 16. Since the second guide arc groove 24 is far away from the center of the main disk 8, and the second guide arc groove 24 is far away from the feed port 11 and the discharge port 13, when the matching column 21 moves to the inside of the second guide arc groove 24, the upper surface of the L-shaped clamp 19 extends into the movable groove 17, and the L-shaped clamp 19 has a pressing and positioning effect on the motor magnetic tile 16.

[0030] The output end of the stepper motor 2 is connected to a central shaft 25 , and the top of the central shaft 25 is connected to the turntable 10 . The stepper motor 2 can drive the turntable 10 to rotate through the central shaft 25 to ensure the normal operation of the device.

[0031] The grinding mechanism 29 includes a semicircular plate 30, a grinding sheet 31 is provided at the bottom of the semicircular plate 30, a vertical rod 26 is fixedly installed on the surface of the third gear 6, a connecting handle 28 is provided on the top of the vertical rod 26 and the surface of the semicircular plate 30, a connecting shaft 27 is installed between the two connecting handles 28 through a rotating shaft, the second gear 5 and the third gear 6 have fewer teeth than the first gear 4, when the first gear 4 rotates one third, the second gear 5 and the third gear 6 rotate one circle, under the mutual cooperation of the gear assembly 3, when the first gear 4 rotates, the second gear 5 and the third gear 6 will also rotate, under the rotation of the third gear 6, the vertical rod 26 on its surface will rotate with the third gear 6, because the semicircular plate 30 and the vertical rod 26 are connected to the connecting shaft 27 through the connecting handle 28, the grinding mechanism 29 will reciprocate under the rotation of the third gear 6, so that the grinding sheet 31 can grind the corners of the motor magnetic tile 16.

[0032] An L-shaped front plate 37 is fixedly provided at the end of the base plate 1, and a T-shaped groove 33 is provided on the surface of the L-shaped front plate 37. A T-shaped slider 32 is provided above the semicircular plate 30, and the T-shaped slider 32 is slidably engaged in the T-shaped groove 33. With the cooperation of the T-shaped slider 32 and the T-shaped groove 33, the third gear 6 can drive the grinding mechanism 29 to perform linear reciprocating motion, so that the grinding sheet 31 can grind the corners of the motor magnet 16.

[0033] The horizontal height of the corners of the motor magnetic shoe 16 is higher than the horizontal height of the upper surface of the turntable 10, so that the grinding mechanism 29 can grind the protruding corners of the motor magnetic shoe 16 during the linear reciprocating motion.

[0034] A receiving groove 34 is provided on the inner wall of the material trough 15, and an extrusion plate 35 is movably provided inside the receiving groove 34. A movable column 36 is provided at the end of the extrusion plate 35, and the movable column 36 passes through the inner wall of the receiving groove 34. When the matching column 21 moves to the inside of the second guide arc groove 24, the upper surface of the L-shaped clamping plate 19 extends into the movable groove 17. At the same time, the surface of the L-shaped clamping plate 19 has an extrusion effect on the movable column 36, so that the extrusion plate 35 can move toward the inside of the material trough 15. Therefore, when the grinding mechanism 29 grinds the corners of the motor magnet 16, the extrusion plate 35 can have an extrusion effect on the motor magnet 16, thereby ensuring the stability of the motor magnet 16 when being grinded and avoiding the movement of the motor magnet 16.

[0035] Working principle: First, the motor magnetic tile 16 can slide into the feed port 11 through the feed pipe 12. When the feed port 11 and one of the troughs 15 are in the same straight line, the motor magnetic tile 16 can slide into the inside of the trough 15, and then the turntable 10 is driven to rotate by the stepper motor 2. When the first gear 4 rotates, the second gear 5 and the third gear 6 will also rotate. Under the rotation of the third gear 6, the vertical rod 26 on its surface will rotate with the third gear 6. Since the semicircular plate 30 and the vertical rod 26 are connected to the connecting handle 28 and the connecting shaft 27, the grinding mechanism 29 will reciprocate under the rotation of the third gear 6. Since the second gear 5 and the third gear 6 have fewer teeth than the first gear 4, when the first gear 4 rotates one-third, the second gear 5 and the third gear 6 rotate one circle, so that the grinding mechanism 29 can grind the motor magnetic tile 16 in the material trough 15 opposite to the feed port 11 and the discharge port 13. Finally, when the material trough 15 and the discharge port 13 are in the same straight line, the motor magnetic tile 16 inside the material trough 15 after grinding can slide into the discharge pipe 14 under the action of gravity, thereby realizing the discharge operation of the motor magnetic tile 16.
