[0002] Coil winding machines are highly automated precision equipment whose core function is to precisely wind wires into stators or coil molds according to a specific number of turns, shape, and direction.

[0003] In existing technology, winding machines require a cutting mechanism and a wire-picking mechanism for cutting and picking the wire during operation. The cutting mechanism is generally a pneumatic shear, including a cutting blade, a drive unit, and a wire fixing unit. The cutting blade consists of a pair of moving blades and a fixed blade. After winding is completed, the wire is clamped using the wire fixing unit, and then the drive unit is activated. The moving blades and the fixed blades cross and close, cutting the wire at the cutting edge within 0.1 to 0.5 seconds.

[0004] However, the structure of the above-mentioned shearing mechanism is relatively complex. This application provides another shearing mechanism that can cut wires. Utility Model Content

[0019] Optionally, the clamping assembly includes a wire clamping rod and a wire clamping drive for moving the wire clamping rod, wherein the wire clamping rod and the shearing head are arranged in parallel.

[0020] By adopting the above technical solution, the clamping component can stably clamp the wire and work in conjunction with the shearing head to ensure the smooth progress of the shearing process, thus simplifying the operation of the winding machine's shearing mechanism.

[0021] Optionally, the wire guide plate has a wire guide groove for wire arrangement, and the wire pressing rod of the shearing head is located on the side of the shearing head away from the wire guide groove.

[0022] By adopting the above technical solution, the wire is arranged along the lead wire groove, and the wire clamping rod is used to effectively clamp the wire on the side away from the lead wire groove, so that the shearing head can smoothly complete the shearing operation.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a cutting mechanism for a self-adhesive coil winding machine.

[0038] Reference Figure 1 A self-adhesive coil winding machine cutting mechanism includes a connecting assembly 1, a wire pull baffle 2, a clamping assembly 3, and a cutting assembly 4. The connecting assembly 1, used for fixed connection with the winding machine, includes a lead wire frame 11 and a connecting block 12. The wire pull baffle 2, the clamping assembly 3, and the cutting assembly 4 are all mounted on the lead wire frame 11. Lead wire wheels 13 for guiding the wire are mounted on both the lead wire frame 11 and the connecting block 12.

[0039] Reference Figure 2 The connecting block 12 is slidably mounted on the lead frame 11, which has a limiting groove 111 for limiting the arrangement of the connecting block 12. The lead frame 11 also has a rotating seat 112 on one side of the limiting groove 111, and an adjusting bolt 113 is mounted on the rotating seat 112. A limiting ring 1131 is fixedly mounted on the adjusting bolt 113, and the bolt head of the adjusting bolt 113 and the limiting ring 1131 abut against opposite sides of the rotating seat 112. The threaded portion of the adjusting bolt 113 is threadedly engaged with the connecting block 12, so that rotating the adjusting bolt 113 can drive the connecting block 12 to move back and forth in the limiting groove 111, thereby adjusting the tension of the wire.

[0040] Reference Figure 3 The wire guide plate 2 is generally rectangular and has a wire guide groove 21 for wire arrangement. The shearing assembly 4 includes a shearing head 41 and a shearing drive 42 for driving the shearing head 41 to move. In this embodiment, the shearing drive 42 is a cylinder, which is fixed to the wire guide frame 11 by bolts, and the piston rod is perpendicular to the extension direction of the wire guide groove 21.

[0041] The shearing head 41 is generally rod-shaped, and its end has a shearing clearance groove 411 for wire arrangement. A shearing inclined surface 412 is provided on the inner wall of the shearing clearance groove 411. The inclination angle of the shearing inclined surface 412 is 130-135°, and in this embodiment, it is 133°. The shearing inclined surface 412 causes the shearing head 41 to form a shearing tip 413 in the shearing clearance groove 411, which cuts the wire.

[0042] To improve the stability of the shearing head 41, the wire guide plate 2 has a limiting arrangement hole 22 for the end of the shearing head 41. During the winding process, the wire is arranged in the shearing relief groove 411. After the winding is completed, the shearing drive 42 is activated, causing the shearing tip 413 to move toward the wire and cut it.

[0043] The piston rod of the shearing drive 42 is provided with a shearing connector 43 that connects to the shearing head 41. The shearing connector 43 is generally rectangular, with one end fixedly connected to the piston rod of the shearing drive 42, and the other end having a snap-fit ​​groove 431 that engages with the shearing head 41. The shearing head 41 has a connecting ring groove 414 at the end away from the shearing clearance groove 411 that engages with the snap-fit ​​groove 431.

[0044] Reference Figure 3 and Figure 4 The lead frame 11 has a guide block 114 corresponding to the limiting arrangement hole 22. The guide block 114 has a guide through hole 1141 that passes through both end faces and allows the shearing head 41 to pass through. The guide block 114 can abut against the shearing connector 43, thereby limiting the maximum movement distance of the shearing head 41.

[0045] The clamping assembly 3 is located between the shearing assembly 4 and the lead-in groove 21. The clamping assembly 3 includes a wire-pressing rod 31 and a wire-pressing drive component 32 that drives the wire-pressing rod 31 to move. The wire-pressing drive component 32 is a prior art push cylinder, and its output shaft is coaxially fixed with the wire-pressing rod 31. The wire-pressing rod 31 and the shearing head 41 are arranged in parallel. By setting up the clamping assembly 3 and the lead-in groove 21, the two ends of the wire on the wire pull baffle 2 can be limited, reducing the probability of the wire shaking and failure to cut during the shearing process of the shearing assembly 4.

[0046] The implementation principle of the self-adhesive coil winding machine shearing mechanism in this application embodiment is as follows: the wire is guided from the guide wheel 13 to the lead groove 21 of the pull baffle 2. During the winding process, the wire is arranged in the shearing clearance groove 411. After the last turn of winding is completed, the clamping drive is activated first to press the wire clamping rod 31 against the pull baffle 2. Then the shearing drive 42 is activated to move the shearing inclined surface 412 toward the wire, so that the wire is cut in a short time.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
