In addition, the forms of the various structures recorded in the following embodiments are merely examples. The present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3 The present invention provides a rotary cutting mechanism for voice coil tubular bobbin material, comprising a mounting frame 3. A roll 7 for placing the voice coil bobbin is fixed to one side of the mounting frame 3 via bolts. A rotating base 1 is rotatably connected to one side of the mounting frame 3, and the roll 7 passes through the rotating base 1. A power assembly is provided on one side of the mounting frame 3 for driving the rotating base 1 to rotate. A plurality of chutes 9 are formed on one side of the rotating base 1, and push blades 10 are slidably connected within each of the chutes 9. A cutting blade 8 is fixed to one side of the push blade 10 via bolts, and the cutting blade 8 moves within the chutes 9. A connecting assembly is provided on the outer side of the rotating base 1 for driving the cutting blade 8 to move. The voice coil bobbin is placed on the roll 7, and the connecting assembly brings the cutting blade 8 into contact with the material of the voice coil bobbin via the connecting assembly. The rotating base 1 is then rotated by the power assembly, which drives the cutting blade 8 to rotate, causing the cutting blade 8 to rotary-cut excess material. Manual cutting is no longer required, saving time and improving efficiency.

[0022] In the present invention, the connecting assembly includes a plurality of bases 12, a plurality of bases 12 are fixed to the outside of the rotating seat 1 by bolts, a plurality of bases 12 are rotatably connected to the connecting arm 11, a plurality of push knives 10 are provided with a socket on one side, the connecting arm 11 is inserted into the socket and leaves a movable space, the outer side of the rotating seat 1 is slidably connected to the sliding sleeve 16 through a keyway, a plurality of bases 2 15 are fixed to the outer side of the sliding sleeve 16 by bolts, and the connecting arm 11 extends into the base 2 15, and an inclined The groove 13 is provided with a stopper 14 in the inclined groove 13, and the stopper 14 is fixed to the base 2 15. A driving assembly for moving the sleeve 16 is provided on one side of the mounting frame 3. The driving assembly includes a threaded rod 4, which is rotatably connected to the mounting frame 3, and one end of the threaded rod 4 passes through the mounting frame 3. The outer side of the threaded rod 4 is threadedly connected to the slide 2, and the slide 2 passes through the mounting frame 3 to move the slide 2 horizontally. An annular groove 17 is provided on the outer side of the slide 16. Two rollers 18 are rotatably connected to the slide 2. The two rollers 1 8 are extended into the annular groove 17 and roll in the annular groove 17. A servo motor 6 is fixed to one side of the mounting frame 3 by bolts. One end of the threaded rod 4 and the output shaft of the servo motor 6 are key-connected with a synchronous pulley 5. The two synchronous pulleys 5 are connected by a belt drive. When the servo motor 6 is started to rotate, the servo motor 6 drives the threaded rod 4 to rotate through the synchronous pulley 5 and the belt. The threaded rod 4 engages with the thread between the slide 2 to make the slide 2 move horizontally. The slide 2 will extend into the annular groove 17. The roller 18 drives the sliding sleeve 16 to move, and the sliding sleeve 16 drives the base 2 15 to move. During the movement of the base 2 15, the blocking rod 14 moves in the inclined slot 13, so that the connecting arm 11 is tilted at one end and lowered at the other end with the base 12 as the rotation point. Since the lowered end of the connecting arm 11 is inserted into the socket on the push knife 10, the connecting arm 11 pushes the push knife 10 to move in the slide slot 9. The push knife 10 pushes the cutting knife 8 to move, so that the cutting knife 8 contacts the material of the voice coil bobbin.

[0023] Multiple bases 12 are evenly distributed on the outside of the rotating base 1, and multiple bases 2 15 are evenly distributed on the outside of the sliding sleeve 16. Multiple bases 2 15 correspond one to one with multiple bases 12. The power component includes a servo motor 21. The servo motor 21 is fixed in the mounting frame 3 by bolts. One end of the output shaft of the servo motor 21 passes through the mounting frame 3 and is keyed to the driving pulley 20. The outer key of the rotating base 1 is connected to the driven pulley 19. The driving pulley 20 and the driven pulley 19 are connected by belt transmission. Multiple cutting knives 8 are evenly distributed with the winding roller 7 as the center. When the cutting knife 8 comes into contact with the material of the voice coil frame, the servo motor 1 6 is turned off and the servo motor 2 21 is started. The servo motor 2 21 will drive the rotating base 1 to rotate through the cooperation of the driving pulley 20 and the driven pulley 19.

[0024] The working principle of the present invention is as follows: when in use, the voice coil skeleton is put on the winding roller 7, and then the servo motor 16 is started to rotate. The servo motor 16 drives the threaded rod 4 to rotate through the synchronous pulley 5 and the belt. The threaded rod 4 engages with the slide 2 to make the slide 2 move horizontally. The slide 2 drives the sliding sleeve 16 to move through the roller 18 extending into the annular groove 17. The sliding sleeve 16 drives the base 2 15 to move. During the movement, the base 2 15 will make the blocking rod 14 move in the inclined groove 13, so that the connecting arm 11 is tilted at one end with the base 12 as the rotation point and the other end is lowered. Since the lowered end of the connecting arm 11 is inserted into the socket on the push knife 10, the connecting arm 11 will push the push knife 10 to move in the slide groove 9. The push knife 10 will push the cutting knife 8 to move, so that the cutting knife 8 contacts the material of the voice coil frame, and then the servo motor 1 6 is turned off and the servo motor 2 21 is started. The servo motor 2 21 will drive the rotating seat 1 to rotate through the cooperation of the active pulley 20 and the driven pulley 19. The rotating seat 1 will drive the cutting knife 8 to rotate, so that the cutting knife 8 will peel and cut the excess material. The staff does not need to cut manually, which saves time and improves efficiency. The rotating seat 1 will drive the base 1 12 to rotate during the rotation process. The base 1 12 will drive the base 2 15 to rotate through the connecting arm 11. The base 2 15 will drive the sliding sleeve 16 to rotate, so that the roller 18 rolls in the annular groove 17, reducing the friction of the sliding sleeve 16.
