[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1 and 2, in one particular embodiment, a rotary shuttle 100 includes: the shuttle race 110 is provided with a mounting surface 130, and a first magnet 131 is arranged in the mounting surface 130; the inner shuttle 120 is arranged in the shuttle race 110, the second magnet 121 is arranged on one side of the inner shuttle 120 close to the mounting surface 130, and attraction force is generated between the first magnet 131 and the second magnet 121.
The inside of the shuttle race 110 is hollow, a semi-cylindrical protrusion is arranged at one end of the shuttle race 110, the side of the protrusion end close to the inside of the shuttle race 110 is an installation surface 130, the installation surface 130 is a plane, the first magnet 131 is arranged in the installation surface 130, the first magnet 131 is arranged in the middle of the installation surface 130, the inner shuttle 120 is arranged in the shuttle race 110, the bottom surface of the inner shuttle 120 is close to one side of the installation surface 130, the bottom surface is circular and is internally provided with the second magnet 121, a gap is reserved between the bottom surface of the inner shuttle 120 and the installation surface 130, and attraction force is generated between the second magnet 121 and the first magnet 131.
In the related art, the gap between the inner shuttle 120 and the mounting surface 130 is easily changed during the high-speed rotation of the rotary shuttle 100, which causes the too large outgoing resistance of the upper end guide rail, and the situation of line jamming and line breaking is easily caused after long-time operation.
When the sewing machine 300 works, a needle of the sewing machine 300 sends a sewing thread on the needle into the rotating shuttle 100 through the needle passing groove on the inner shuttle 120, the rotating shuttle 100 forms the sewing thread into a knot by rotating the hook thread and completing the routing in the rotating shuttle 100, an attractive force is generated between the first magnet 131 and the second magnet 121, when the shuttle bed 110 deviates towards the direction far away from the inner shuttle 120, the attractive force generated between the first magnet 131 and the second magnet 121 can prevent the shuttle bed 110 from continuously moving towards the inner shuttle 120, and the shuttle bed 110 is attracted to return to the normal working position, so that the size of the gap is reduced, and the routing at the guide rail at the upper end of the rotating shuttle 100 is easier.
Preferably, the first magnet 131 and the second magnet 121 are selected to have a circular shape, so that the same attractive force can be maintained during the rotation of the rotary hook 100.
The attractive force generated between the first magnet 131 and the second magnet 121 reduces the gap between the shuttle bed 110 and the inner shuttle 120, widens the routing path at the upper end, reduces the thread-out resistance of the sewing thread, avoids the occurrence of thread jamming, thread breakage and the like, and improves the stability of the rotating shuttle 100.
[ second embodiment ]

The third magnet 141 further increases the attraction between the mounting surface 130 and the bottom of the inner shuttle 120, ensures the temperature of the gap between the inner shuttle 120 and the shuttle bed 110, ensures the smooth routing of the sewing thread in the guide rail, and further increases the stability of the rotating shuttle 100.
[ third embodiment ]
In a specific embodiment, there is at least one receiving groove 140, each receiving groove 140 has a third magnet 141 therein, a plurality of receiving grooves 140 are disposed around the second magnet 121, and the centers of the receiving grooves 140 are concentric.
The number of the accommodating grooves 140 is four, the four accommodating grooves 140 are identical in structure, are all disposed on the mounting surface 130, and are evenly distributed along the surface of the mounting surface 130, the distance from the center of each accommodating groove 140 to the center of the rotary shuttle 100 is equal, a third magnet 141 is mounted inside the accommodating groove 140, the third magnet 141 is circular, and the center of the third magnet 141 coincides with the center of the surface of the accommodating groove 140.
In the rotating process of the rotating shuttle 100, attractive forces are generated between the four third magnets 141 and the second magnet 121 respectively, so that the gap between the inner shuttle 120 and the mounting surface 130 is more stable, and the four third magnets 141 are uniformly distributed, so that when the rotating shuttle 100 rotates at any angle, the forces applied to the inner shuttle 120 are consistent, and the phenomenon that the inner shuttle 120 inclines due to inconsistent stress, a certain gap of a routing track is reduced, and the outgoing resistance is increased is avoided.
The arrangement of the plurality of third magnets 141 increases the attractive force received by the inner shuttle 120, so that the gap between the inner shuttle 120 and the mounting surface 130 is more stable, and the arrangement of the plurality of accommodating grooves 140 uniformly enables the attractive force received by the inner shuttle 120 to be consistent all the time in the rotating process of the rotating shuttle 100.
[ fourth example ] A
