[0002] A magnetic ring winding machine is a device that winds wire onto a magnetic ring to make electronic components such as inductors. For example, in the production process of products such as leakage protectors and smart meters, the wire storage ring is arranged to rotate in the vertical direction, and the magnetic ring is arranged to rotate in the horizontal direction. The winding wire is wound on the magnetic ring through the rotation of the magnetic ring and the wire storage ring. After the winding is completed, the winding wire wound on the magnetic ring needs to be cut off from the output end of the wire supply mechanism by a cutting device, which facilitates the winding of the next magnetic ring while also leaving wire feet on the winding wire on the previous magnetic ring for winding on the pins.

[0003] However, in the existing cutting device, the cutter is arranged laterally on the fixed seat, that is, the blade of the cutter is arranged vertically, which makes it easy for the winding wire to fail to be cut when the winding wire is in a loose state, affecting subsequent production; at the same time, the connection between the cutter and the driving component is a pin connection, which requires additional pin material costs; therefore, a winding wire cutting device is urgently needed to solve the above problems.

[0048] Specifically, after the pin allowance is limited, the second driving component 410 drives the first clamping component 420 to move along the X-axis toward the side where the second clamping component 430 is located, so that both pins are clamped by the second clamping component 430, and then the second driving component 410 drives the first clamping component 420 to move along the X-axis toward the side where the third clamping component 440 is located. Due to the different lengths of the two pins, the first pin is clamped at the second clamping component 430 (at this time, the first pin is in contact with the first pin 641), and the second pin is driven to the third clamping component 440 and clamped (at this time, the second pin is in contact with the second pin 641), completing the line division.

The rotating component is installed at the output end of the tenth drive component, and the sleeve 520 is installed on the rotating component. The rotating component is used to drive the sleeve 520 to rotate around the Y-axis; when wrapping the pin, the ninth drive component 800 is first used to drive the base and the second workpiece 650 thereon to move along the Z-axis to the bottom of the sleeve 520, and then the tenth drive component is used to drive the sleeve 520 close to the second workpiece 650 until it is inserted into the pin 641. When the sleeve 520 clamps the pin, the rotating component drives the pin to rotate synchronously, so that the pin is wrapped around the pin 641.

[0052] In one embodiment, the lower end of the sleeve 520 has a lateral notch 530 so that the stitching pin can enter the lateral notch 530 when the sleeve 520 rotates; when the sleeve 520 moves downward to abut the stitching pin, during the rotation of the sleeve 520, the stitching pin is first stuck in the lateral notch 530, so that the stitching pin can rotate with the sleeve 520, thereby achieving the stitching pin being wrapped around the stitching pin 641.

[0053] 6) It should be noted that the drivable components in the present invention can adopt existing motors, cylinders and other mechanisms, and the handling device can adopt existing one-dimensional, two-dimensional or even three-dimensional motion systems.
