When the coil is wound, the driving member 41 is advanced to bring the mounting plate 42 close to the insulating strip 7, and then the clamping jaws 43 clamp the sleeve 6.
The driving member 41 then advances the mounting plate 42 to move closer to the insulating strip 7 to press the sleeve 6 against the insulating strip 7, so that the insulating strip 7 slides into the interior of the sleeve 6. In the process, the inner wall of the slot 71 in the shape of an arc presses the rotating bar 82 so that the rotating bar 82 rotates gradually until being level with the insulating bar 7. And because the insulating strip 7 slides and stretches into the inner cavity of the sleeve body 6, the insulating strip 7 also pushes the shifting block 811 on the limiting strip 81, so that after the rotating strip 82 rotates until the rotating strip is horizontal to the insulating strip 7, the clamping jaw 43 continuously pushes the sleeve body 6, the insulating strip 7 continuously pushes the limiting strip 81, the extension 813 on the limiting strip 81 is moved to the position close to the rotating strip 82, and one side surface of the rotating strip 82 away from the insulating strip 7 is attached to the surface of the extension 813. At this time, the rotating strip 82 is difficult to rotate under the limitation of the extension section 813, the rotating strip 82 does not limit the circumference side of the insulating strip 7 any more, and then the driving piece 41 drives the mounting plate 42 to be far away from the insulating strip 7, so that the sleeve body 6 is pulled out from the insulating strip 7, the sleeve body 6 is automatically separated from the insulating strip 7 quickly, and the automatic production operation of the coil is completed.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
