Description

Technical Field

[0001] This invention relates to the field of flying fork winding machine technology, and specifically to a waste-free wire device for flying fork winding machines. Background Technology

[0002] Previous designs sometimes resulted in excessively long start and end lines.

[0003] When the initial wire is attached, the wire-cutting and clamping mechanism cannot get close to the workpiece, so the initial wire mechanism presses the copper wire onto the spindle. First, the first pole wire is wound up, and then the wire-cutting and clamping mechanism releases the initial wire, resulting in a relatively long initial wire. Furthermore, because the wire attachment position is fixed, automatic wire attachment to the commutator is not possible.

[0004] When the tail wire is cut, the wire clamping mechanism moves up and down to clamp the copper wire, but it cannot cut to the root of the commutator of the rotor workpiece, and a very long tail wire will be generated.

[0005] Based on the above, this invention proposes a waste-free wire device for a flying fork type wire reel, which can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a waste-free wire device for a fly fork type wire winding machine. This waste-free wire device is easy to use.

Feeding does not affect the winding action. Simultaneously, it is equipped with a vertical servo module and an inclined servo module to automatically attach the wire to the workpiece commutator and automatically cut and clamp the start and end wires.

[0007] This invention is achieved through the following technical solution:

[0008] A fly fork type winding machine with no waste wire includes a frame, on which a workpiece temporary placement table, a rotary conveying mechanism, a workpiece winding table and a fly fork type winding machine are sequentially arranged.

[0054] The working principle of one embodiment of the present invention is as follows:

[0055] A waste-free wire device for a flying fork type wire winding machine includes a telescopic cylinder 33 that controls the extension of a cylinder gripper 31. After the cylinder gripper 31 grabs the workpiece on the workpiece temporary table 2, a lifting cylinder 34 raises the cylinder gripper 31, a rotating cylinder 32 rotates the cylinder gripper 31, and the lifting cylinder 34 lowers the cylinder gripper 31, releasing the workpiece. A laser sensor 45 detects whether the workpiece is in position. If the workpiece is not in position, a motor 41 controls the workpiece seat 42 to rotate to the accurate position.

[0056] Two servo modules, one vertical and one at a 45° angle, precisely deliver the shear clamp 534 to the commutator position of the rotor workpiece. The spindle rotates, hooking the copper wire onto the commutator. The starting wire fixture clamps the starting wire. After the shear clamp 534 retracts, the operation is complete. Winding begins. The commutator sheath descends to prevent the copper wire from colliding with the commutator and causing wire damage during winding.

[0057] The tail wire is cut by two servo modules in the vertical and 45° directions, which precisely deliver the shear clamp 534 to the copper wire tail of the rotor workpiece for cutting and clamping.
