Description

Technical Field

[0001] This utility model relates to the field of stator winding technology, specifically to a needle-type external winding mechanism with no waste wire. Background Technology

[0002] In the manufacturing process of electric motors, stator winding is one of the core processes, and its winding quality directly affects the motor's performance, service life, and operational stability. Currently, existing winding devices have many shortcomings: Firstly, existing winding devices produce wire ends, which need to be cut off as waste wire. Secondly, the lack of an effective wire clamping and fixing structure after winding makes the enameled wire prone to loosening, requiring an additional fixing process and reducing production efficiency. In addition, the existing winding device's wire nozzle does not match the trajectory of the winding positioning component on the stator, resulting in unstable cooperation between the enameled wire and the positioning component during the winding process, affecting the winding quality.

[0003] These problems not only increase production costs, but also make it difficult to meet the high precision and high reliability requirements of automotive motors. Therefore, there is an urgent need for an optimized stator pin-type external winding waste wire mechanism to solve the above defects. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a needle-type external winding mechanism with zero waste wire. It achieves high-precision coordination between the wire nozzle lifting and stator rotation, ensuring neat arrangement of the enameled wire, improving the stability of the enameled wire after winding, while simplifying the process and increasing production efficiency.

[0005] To solve the above technical problems, this utility model achieves the following solution: A needle-type external winding waste-free thread mechanism of this utility model includes: The support frame is driven by a lifting mechanism to perform lifting and lowering actions; The wire nozzle is vertically fixed to the end of the bracket and has through holes through both ends for the enameled wire to pass through. The stator is horizontally fixed to the upper end of a stator fixture, and the stator rotates synchronously with the stator fixture, which is driven to rotate by a rotary drive mechanism. The stator includes: The central circular structure; The T-shaped structural members distributed on the side circumference of the circular structural part in a ring array, with two adjacent T-shaped structural members forming a winding space and a gap provided at the outer ends of two adjacent T-shaped structural members; The device includes multiple double-hook components arranged in a ring array on the annular surface of the circular structure. The hooks of each double-hook component are positioned away from the T-shaped structure. The rotational trajectory of the double-hook component intersects with the vertical movement trajectory of the line tip.

[0006] Furthermore, the power source of the lifting mechanism is a servo motor.

[0007] Furthermore, the bracket is an L-shaped structure with its vertical rod pointing downwards, and the lower front side of the vertical rod is vertically connected to the wire nozzle.

[0008] Furthermore, the power source of the rotary drive mechanism is a servo motor.

[0009] Furthermore, the double hook component is provided in three sets, and the three sets of double hook components are distributed at equal angles on a circumferential surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The needle-type external winding wasteless wire mechanism of this utility model has high winding accuracy and efficiency: both the lifting mechanism and the rotary drive mechanism are driven by servo motors to realize the coordinated control of wire nozzle lifting and stator rotation, resulting in high winding accuracy. At the same time, the high responsiveness of the servo motor can improve the winding speed, thus improving efficiency compared with the traditional needle-type external winding wasteless wire mechanism.

[0011] The needle-type external winding waste-free wire mechanism of this utility model has a regular enameled wire arrangement and low damage rate: the T-shaped structural component forms an independent winding space, avoids interference between enameled wires in adjacent areas, ensures a regular winding arrangement, and reduces the damage rate of the enameled wire insulation layer.

Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-3 The present invention relates to a needle-type external winding waste-free thread mechanism, comprising: Support 1 is driven by a lifting mechanism to perform lifting and lowering actions; The wire nozzle 2 is vertically fixed to the end of the bracket 1 and has through holes through both ends for the enameled wire to pass through. The stator 3 is horizontally fixed to the upper end of the stator fixture 4. The stator 3 rotates synchronously with the stator fixture 4, and the stator fixture 4 is driven to rotate by a rotary drive mechanism. The stator 3 includes: The central circular structure; The T-shaped structural members 32 distributed on the side circumference of the circular structure are arranged in a ring array. Two adjacent T-shaped structural members 32 form a winding space and the outer ends of two adjacent T-shaped structural members 32 are provided with a gap. The device has multiple double-hook components, which are arranged in a ring array on the annular surface of the circular structure. The hooks 31 of each double-hook component are positioned away from the T-shaped structure 32. The rotation trajectory of the double-hook components intersects with the up-and-down movement trajectory of the line nozzle 2.

[0021] The power source for the lifting mechanism is a servo motor.

[0022] The bracket 1 is an L-shaped structural component with its vertical rod facing downwards. The lower front side of the vertical rod is vertically connected to the wire nozzle 2.

[0023] The power source for the rotary drive mechanism is a servo motor.

[0024] The double-hook component is provided in three sets, and the three sets of double-hook components are distributed at equal angles on a circular surface.

[0025] Example 2: The following is the working principle of this utility model's needle-type external winding waste-free wire mechanism after being applied to motor stator equipment: The lifting mechanism is connected to the bracket 1 via a ball screw transmission mechanism. The lower front side of the vertical rod of the bracket 1 is fixed to the wire nozzle 2 by bolts and positioning pins. The diameter of the through hole of the wire nozzle 2 is set according to the diameter of the enameled wire. The wire nozzle 2 is a replaceable installation structure.

[0026] The rotary drive mechanism uses the same model of servo motor as the lifting mechanism. It is connected to the stator fixture 4 through a reducer. Three sets of double hook components are distributed at an angle of 120° and horizontally fixed on the stator fixture 4, and are fastened with screws.

[0027] Winding process: ① The treatment of the starting wire of the winding: the enameled wire end is controlled by the lifting mechanism to move to one of the double hook components, so that the enameled wire end is pulled out a distance along the inside of the two hooks.

[0028] ②The tail-top pressing fixture 5 presses down to press the pulled-out enameled wire end onto the stator.

[0029] ③ The enameled wire is wound onto the T-shaped structure 32 of the stator by the rotation of the stator 3 and the up-and-down movement of the wire nozzle 2. During the winding process, the tail-top wire pressing fixture 5 rotates synchronously with the stator 3.

[0030] ④ After the winding is completed, the tail-top pressing fixture 5 is raised a certain distance, and the end of the enameled wire is wound around the hook 31 where the end of the enameled wire is located again.

[0031] ⑤ Start the tail top pressure fixture 5 to descend, press down the end of the enameled wire and flatten the terminal.

[0032] ⑥ Start the cutting fixture 6 to cut the end of the enameled wire, forming a shape like... Figure 3 The diagram shows the structure after the stator wires are wound around.

[0033] ⑦ Reset all components, remove the wound stator, and replace it with a new stator 3.

[0034] In summary, the needle-type external winding waste-free wire mechanism of this invention boasts high winding accuracy and efficiency: both the lifting mechanism and the rotary drive mechanism are driven by servo motors, achieving coordinated control of the wire nozzle lifting and stator rotation, resulting in high winding accuracy. Simultaneously, the high responsiveness of the servo motor enhances winding speed, leading to improved efficiency compared to traditional needle-type external winding waste-free wire mechanisms. Furthermore, the needle-type external winding waste-free wire mechanism of this invention features neat enameled wire arrangement and a low damage rate: the T-shaped structural component forms an independent winding space, avoiding interference between adjacent areas of enameled wire, ensuring neat winding arrangement, and reducing the damage rate of the enameled wire insulation layer.
