Description

Technical Field

[0001] This utility model relates to a double-sided processing device for arc-shaped magnets. Background Technology

[0002] Magnet tiles are a type of permanent magnet primarily used in permanent magnet motors. The process involves several complex steps, including raw material preparation, molding, sintering, polishing, and magnetization. During the polishing process, both the inner and outer surfaces of the magnet tile need to be polished separately. Due to the tile's unique shape, polishing is often done in stages, requiring manual flipping between polishing operations, resulting in low processing efficiency. Utility Model Content

The first grinding roller has a grinding groove in the middle circumferentially that matches the convex surface of the magnetic tile. The rotation direction of the first grinding roller is opposite to the conveying direction of the first conveyor belt. The first support roller extends radially in the middle to form a boss that matches the concave surface of the magnetic tile.

[0006] The reversing feeding belt has a trough along its length in the middle for accommodating the magnetic tile. The upper opening of the trough is bent towards each other to form a flange. The direction of the trough is gradually rotated downwards by 180° from left to right.

The second grinding roller has a grinding boss in the middle circumferential direction that matches the concave surface. The rotation direction of the second grinding roller is opposite to the conveying direction of the second conveyor belt.

[0015] The beneficial effects of this utility model are as follows:

[0016] The device automatically flips the magnetic tile 180° up and down by setting a reversing feeding belt, and then uses the first grinding mechanism and the second grinding mechanism to continuously complete the grinding process on both sides of the magnetic tile.

The first support roller 6 extends radially in the middle to form a boss 61 that matches the concave surface 22 of the magnetic tile 2 (see...). Figure 3 The first grinding roller 7 has a first auxiliary feeding roller 4 on its left side. The first auxiliary feeding roller 4 rotates in the opposite direction to the first grinding roller 7. The first auxiliary feeding roller 4 has a groove 41 in the middle that matches the convex surface 21 (see...). Figure 2 The first conveyor belt 1 has first side baffles 3 extending to the left side of the first auxiliary feeding roller 4 on both the front and rear sides. The first support roller 6 has first feeding guide block 5 and first discharging guide block 8 on the left and right sides respectively. The first feeding guide block 5 is connected to the first conveyor belt 1, and the first discharging guide block 8 is connected to the left end of the reversing feeding belt 9.

[0028] The reversing feeder belt 9 has a trough 91 along its length in the middle for accommodating the magnetic tile 2. The upper opening of the trough 91 is bent towards each other to form a flange 92. The trough 91 is rotated downwards 180° from left to right (see...). Figure 4 , Figure 5 );

[0029] The second grinding mechanism includes a second grinding roller 15 and a second support roller 14 arranged vertically. The second grinding roller 15 has a grinding boss 151 circumferentially arranged in the middle, which matches the concave surface 22. The rotation direction of the second grinding roller 15 is opposite to the conveying direction of the second conveyor belt 10. The second support roller 14 has a groove I 141 circumferentially arranged in the middle, which matches the convex surface 21 (see...). Figure 7 The second grinding roller 15 has a second auxiliary feeding roller 12 on its left side. The rotation direction of the second auxiliary feeding roller 12 is opposite to that of the second grinding roller 15. The second auxiliary feeding roller 12 has a boss I 121 in the middle that matches the concave surface 22 (see...). Figure 6 The second conveyor belt 10 has second side baffles 11 on both the front and rear sides that extend to the left side of the second auxiliary feeding roller 12. The left end of the second side baffle 11 is connected to the right end of the reversing feeding belt 9. The left side of the second support roller 14 has a second feeding guide block 13 that connects to the second conveyor belt 10. The right side of the second support roller 14 has a discharge conveyor belt 16. The first support roller 6 and the second support roller 14 are both follower structures.

[0030] The device automatically flips the magnetic tile 180° up and down by setting a reversing feeding belt, and then uses the first grinding mechanism and the second grinding mechanism to continuously complete the grinding process on both sides of the magnetic tile. No manual reversing is required, which improves grinding efficiency.

[0031] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0032] During operation, the magnetic tiles are arranged sequentially on the first conveyor belt and move from left to right (initially with the convex surface facing up). When the magnetic tile moves to below the first auxiliary feeding roller, the grooved surface of the first auxiliary feeding roller contacts the convex surface of the upper part of the magnetic tile. As the first auxiliary feeding roller rotates, it exerts a rightward thrust on the magnetic tile. Simultaneously, the magnetic tile on the left side also continuously moves to the right, generating a rightward force, ensuring that the magnetic tile passes between the first grinding roller and the first support roller. During the process of the magnetic tile moving to the right through the first grinding roller and the first support roller, the first grinding roller evenly grinds the upper convex surface of the magnetic tile, while the first support roller mainly provides support for the magnetic tile. After the magnetic tile moves out of the first grinding roller and the first support roller, it moves along the first discharge guide block into the trough of the reversing feeding belt. As the magnetic tile moves, it slides along the trough to the right side of the reversing feed belt to complete the reversing. After moving out of the reversing feed belt, it falls onto the second conveyor belt with the concave surface of the magnetic tile facing upwards. The magnetic tile then moves to the bottom of the second auxiliary feed roller. The surface of the boss I in the middle of the second auxiliary feed roller contacts the concave surface of the magnetic tile. As the second auxiliary feed roller rotates, the magnetic tile on the second auxiliary feed roller also generates a rightward thrust. Combined with the rightward thrust generated by the alignment of other magnetic tiles on the left, this ensures that the magnetic tile passes between the second grinding roller and the second support roller. During the process of the magnetic tile moving to the right and passing through the second grinding roller and the second support roller, the second grinding roller evenly grinds the upper convex surface of the magnetic tile. The second support roller mainly supports the magnetic tile. When the magnetic tile moves out of the space between the second grinding roller and the second support roller, it is finally discharged along the discharge conveyor belt.

[0033] In this embodiment, the magnetic tile is polished before the magnetization process, and the magnetization process is carried out after both sides are polished.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
