After the wire body 50 passes through the feed channel 10, the tail end of the wire body 50 is bent to form a tail end section. The tail end section is docked with the wire body 50 at the welding position 40. The ultrasonic vibrator 30 is used to drive the welding head 20 to weld downward, and the tail end section is welded to the wire body 50 to form a tail ring 51.
[0025] The ultrasonic welding equipment for the tail ring 51 of the wire body 50 provided above provides the wire body 50 for insertion through the feed channel 10, and then the tail end section of the wire body 50 is bent manually or mechanically to form the tail ring 51, and the ultrasonic vibrator 30 is used to drive the welding head 20 to weld the tail end section to the wire body 50, so that the formed tail ring 51 is uniform in size, and the problem of excessive knot points is eliminated through welding, thereby improving the production efficiency; the tail ring 51 of surgical sutures is usually made by manual knotting, which is difficult, has low production efficiency, and has the problem of knots.
[0026] In this embodiment, the feed channel 10 includes an inlet channel 11 and a wire position channel 12 for the wire body 50 to pass through the feed channel 10, and an outlet channel 13 for the wire body 50 to pass through the feed channel 10. The two ends of the wire position channel 12 are respectively connected to the inlet channel 11 and the outlet channel 13. A welding opening 14 is opened in the wire position channel 12 for the tail end section to be inserted.
[0027] The tail end of the wire body 50 can enter the wire position channel 12 from the inlet channel 11, and then exit from the outlet channel 13 on the wire position channel 12, so as to position the wire body 50. The tail end segment of the wire body 50 is bent manually or mechanically so that one end of the tail end segment is inserted into the welding port 14 and abuts against the wire body 50, so that the tail end segment is welded to the wire body 50 through the welding head 20, so that the formed tail ring 51 is of uniform size, and the problem of excessively large rope knots is eliminated through welding, thereby improving production efficiency.
[0028] In this embodiment, the welding port 14 is located in the welding position 40 , so that the tail end of the wire 50 can be inserted into the welding position 40 of the wire track 12 and abut against the welding position 40 of the wire 50 .
[0029] In this embodiment, the feed channel 10 is connected to a curved channel 15 at the tail end of the feeder 50.
