Description

Technical Field

[0001] This invention relates to a wire take-up mechanism for enameled wire, and more particularly to a take-up process and apparatus for producing flat electromagnetic wire. Background Technology

[0002] The production process of flat enameled wire mainly includes steps such as wire passing through round molds, wire passing through flat molds, online short-circuit DC annealing, ultrasonic thermal cleaning with deionized water, coating, baking, applying lubricating oil, and active winding. Winding of enameled flat wire is generally done using ordinary copper round enameled wire winding machines. When changing the spool, manual replacement is required, and the wire end must be manually fixed. The entire winding process requires manual operation in conjunction with the winding machine, resulting in low winding efficiency and high labor costs. Furthermore, the existing wire end fixing method on the spool of copper round enameled wire winding machines is not suitable for flat enameled wire; wire end fixing is cumbersome, and this method can easily affect the quality of some flat enameled wires. Therefore, the existing technology suffers from low winding efficiency and cumbersome wire end fixing. Summary of the Invention

[0036] A pulley is provided on the rotating shaft, and a pulley is also provided at the output end of the rotating motor. A transmission belt is provided between the two pulleys.

[0037] The working process of this invention is as follows: The spool is placed horizontally in the spool hopper. A gate is provided at the bottom of the spool hopper. When the gate is opened, the spool falls to the discharge port under gravity. Under the action of the pushing cylinder, the spool is pushed onto the support frame of the rotary spool conveying mechanism. The wire clamping plate at the inner end of the spool engages with the telescopic locking block to fix and position the spool. Subsequently, the rotary spool conveying mechanism rotates under the action of the rotary motor. The spool with the material loaded rotates to the bottom of the lifting winding drive mechanism. The enameled wire is inserted into the corresponding wire groove and wire clamping plate by the enameled wire conductor mechanism and the wire cutting and feeding mechanism. The lifting hydraulic cylinder descends, driving the rotating sleeve to descend. The clamping groove at the bottom of the rotating sleeve acts on the wire clamping plate to fix and clamp the wire end. Then, the lifting cylinder descends and retracts, causing the telescopic locking block to descend and separate from the clamping plate at the bottom of the spool, facilitating the subsequent rotation of the spool. Then, the spool rotates under the action of the drive motor, and cooperates with the enameled wire feeding mechanism to achieve winding. After winding, the enameled wire is cut by the wire cutters on the wire feeding mechanism. The rotary spool conveying mechanism rotates, rotating the wound spool to the lower end. Under the action of gravity, the spool falls into the discharge hole, and is pushed by the cylinder and the discharge plate to complete the discharge.

[0038] The function of the arc-shaped anti-detachment plate is to prevent the wound spool from falling off during rotation.

[0039] The working process of the wire cutting and feeding mechanism is as follows: When wire cutting is required, the forward and backward moving cylinder operates, driving the movable mounting base to move forward, so that the wire cutter contacts the enameled wire and controls the wire cutter to complete the cutting operation of the enameled wire. After completion, the wire cutter immediately separates from the enameled wire. When the new spool moves to the bottom of the lifting winding drive mechanism, the wire feeding clamp clamps the enameled wire. The first transverse screw assembly drives the wire feeding clamp to move towards the spool, inserting the wire end into the insertion clamp. The insertion clamp clamps the flat electromagnetic wire and exposes the wire end a certain distance. Then, the second transverse screw assembly moves, driving the insertion clamp to move and inserting the wire end into the wire groove and clamping plate.

[0040] The working process of the enameled wire feeding mechanism: The enameled wire passes through the conductor ring, and under the action of the lead screw assembly, it moves up and down, which facilitates the winding and take-up of the enameled wire on the spool.
