[ first embodiment ] A method for manufacturing a semiconductor device

Referring to fig. 1, a month ring 100 according to an embodiment of the present invention includes: the first end of the crescent 10 is provided with a thread take-up tip 20. Wherein, the thread picking tip 20 is used for hooking the thread loop and expanding the thread loop, the thread picking tip 20 protrudes to the top surface of the moon ring body 10, and the width of the thread picking tip 20 is gradually reduced to the side far away from the moon ring body 10.

Specifically, referring to fig. 2, the moon ring body 10 is provided with a shuttle body connecting side 11 located on the bottom surface of the moon ring body 10 for connecting the shuttle body.

Further, the month ring body 10, for example, further includes: and at least one shuttle body connection hole 14 penetrating the top surface of the moon ring body 10 to the shuttle body connection side 11 in the vertical direction. Compared with the method that the shuttle body connecting hole 14 is formed in the side face of the moon ring body 10, the moon ring 100 is easy to deform after being mounted and dismounted for many times in a side face fixing mode due to the fact that the side face of the moon ring body 10 is an arc face, and a fit clearance and working noise are generated. However, the bottom surface of the moon ring body 10 is a flat surface, and the bottom surface of the moon ring body 10 is not easily deformed even after being fixed for many times as the shuttle connecting side 11.

In the present embodiment, since the thread is easily caught into the shuttle connecting side 11 after the thread take-up tip 20 is taken up on the basis that the shuttle connecting side 11 is located on the bottom surface of the lunar ring body 10, it is necessary to provide a stopper or a guide to prevent the thread from being caught.

Preferably, the month ring 100 further includes, for example: and a hemming guide surface 30 located on the shuttle attaching side 11 and attached to the first end. The first end is a vertical plane, one side of the edge covering guide surface 30, which is far away from the first end, is connected with an edge covering bottom surface, and the edge covering bottom surface faces horizontally.

Further, the edge-covering guide surface 30 may be an inwardly concave curved surface, an outwardly convex curved surface, or an inclined surface. For example, the covered edge guide surface 30 is recessed inward, whereby a good guide effect can be obtained.

Still further, a covered edge region 31 is formed between the covered edge guide surface 30 and the month ring body 10. One surface of the edge covering area 31 facing the inner side of the moon ring 100 is an arc-shaped connecting surface, the top surface of the edge covering area 31 is a connecting plane, and the arc-shaped connecting surface and the connecting plane are both located on the shuttle body connecting side 11.

Preferably, referring to fig. 3, the month ring 100 further includes, for example: and a blocking surface 40 located on the shuttle connection side 11 and facing the moon ring body 10. The blocking surface 40 is provided according to the shape of the end surface thereof for blocking, and the blocking surface 40 may be disposed obliquely or vertically on the shuttle connecting side 11. As shown, the blocking surface 40 and the moon ring body 10 are sandwiched to form a blocking area 41.

Preferably, the number of the shuttle connecting holes 14 is multiple and is uniformly distributed on the shuttle connecting side 11. For example, there are three shuttle connecting holes 14, and the side close to the blocking surface 40 is the first shuttle connecting hole 14. The first shuttle body coupling hole 14 can reinforce the coupling of the blocking area 41, and the side of the month ring body 10 facing the thread take-up tip 20 can be more stable and less prone to vibration.

Preferably, in conjunction with fig. 1 and 3, the crescent 10 is provided with opposite bobbin-mounting side 12 and crescent outside 13, and further comprises: and a relief groove 50 provided on the bobbin connecting side 11 and surrounding the bobbin mounting side 12. For example, the tool withdrawal groove 50 is a groove with a square cross section, and the tool withdrawal groove 50 can eliminate burrs and facilitate tool withdrawal.

Further, on the shuttle body attaching side 11, the shuttle body attaching hole 14 is located near the moon ring outside 13 and between the escape groove 50 and the moon ring outside 13.

Still further, an end of the relief groove 50 toward the hemming guide surface 30 is located in the hemming region 31. Further, the relief groove 50 penetrates the hemming guide surface 30 toward one end of the hemming guide surface 30, and the relief groove 50 can also seal the hemming region 31 after the hemming region 31 is assembled. Of course, the tool withdrawal groove 50 may penetrate the end surface of the thread take-up tip 20.

Preferably, the edge guide surface 30 is a plurality of adjacent curved surfaces which are recessed inward. For example, the hemming guide surface 30 includes: a first guide surface 21 and a second guide surface 22 located on the thread take-up tip 20 toward the shuttle connecting side 11, the first guide surface 21 being connected to the outer side 13 of the month circle, and the second guide surface 22 being connected to the side of the first guide surface 21 away from the outer side 13 of the month circle.

Further, the hemming guide surface 30 includes, for example, a third guide surface 23 and a fourth guide surface 24, the third guide surface 23 connecting the thread take-up tip 20 to the bobbin attaching side 12, and the fourth guide surface 24 being interposed between the third guide surface 23 and the second guide surface 22. Wherein the relief groove 50 penetrates the fourth guide surface 24.

Still further, since the third guide surface 23 is recessed inward, the width of the thread take-up tip 20 can be gradually reduced in a direction away from the month ring body 10. By providing a plurality of edge-covering guide surfaces 30, the thread take-up tip 20 can maintain a certain radian at a sharp colleague, facilitating thread take-up and thread loop guiding.

[ second embodiment ]

The rotating shuttle 200 provided by the embodiment of the utility model comprises the moon ring 100 provided by the first embodiment, the shuttle body 110, the shuttle bed, the shuttle core and the coil, and the rotating shuttle 200 is formed by assembling a plurality of parts according to corresponding assembling modes.

Specifically, the shuttle body 110 is provided with, for example, a crescent attachment surface 111, and at least one fixing hole provided in the crescent attachment surface 111, the fixing hole being engaged with the shuttle attachment hole 14, and the crescent 100 is attached to the crescent attachment surface 111 of the shuttle body 110 through the shuttle attachment side 11.

Further, the shuttle body 110 further includes a wrapping end surface 112, for example, and the wrapping end surface 112 is perpendicularly connected to one end of the month ring mounting surface 111. Wherein, after the moon-ring 100 is mounted on the shuttle body 110, the edge-covered end surface 112 is matched with the blocking surface 40, and the connecting seam between the moon-ring mounting surface 111 and the shuttle body connecting side 11 is blocked by the blocking surface 40, thereby preventing the thread from being clamped into the connecting seam.
