Description

Technical Field

[0001] This utility model relates to the field of automated production equipment for electronic components, and in particular to a lead winding device for electronic components. Background Technology

[0002] In the manufacturing process of electronic components, lead winding is one of the key processes, especially for components with complex pin structures such as common-mode inductors. Traditional manual lead winding suffers from low efficiency, poor consistency, and easy damage to the leads. Existing automated lead winding equipment is mostly designed for single structures, making it difficult to achieve multi-station collaborative operation. Furthermore, when handling complex actions such as clamping, stretching, and winding multiple strands of wire, defects such as lead misalignment and uneven winding tightness are prone to occur, resulting in low product yield. Therefore, there is an urgent need for an automated device that can achieve multi-structure collaborative operation and ensure winding stability. Utility Model Content

[0003] The purpose of this invention is to provide an electronic component lead winding device. Through the modular design and collaborative operation of the lead winding structure, the lead winding structure, and the clamping structure, it can achieve high-precision and high-efficiency winding of complex electronic component leads, solving the problems of poor stability and low automation in traditional processes.

[0004] To achieve the above objectives, this utility model provides an electronic component lead winding device, including a lead-supporting structure.

A second cylinder is provided on the side of the lead clamping module near the first frame. The second cylinder controls the lead clamping module to move relative to the lead fixing module along the X-axis in the horizontal direction.

[0011] Preferably, the lead wire fixing module includes an upper fixing block and a lower fixing block. A second linkage block is provided on the side of the lower fixing block away from the lead wire clamping module. A third cylinder is provided on the upper surface of the second linkage block.

[0015] (1) Multi-structure collaborative operation: The wire-guiding structure, winding structure and clamping structure are linked by the power unit to complete the winding of multiple strands of complex components such as common mode inductors, breaking through the limitations of traditional single-station equipment.

[0016] (2) The guide rod works in conjunction with the lead wire clamping module and the fixing module to ensure uniform tension of the lead wire during the winding process through a closed-loop control of "clamping-stretching-fixing" to avoid deviation or breakage.

[0017] (3) Automation and high efficiency: The combination of a three-axis feed motor and a cylinder drives the entire foot wrapping process, reducing manual intervention and improving production efficiency and product consistency.

[0049] Furthermore, the number of clamping modules 92, winding components 71, and guide rods 32 are the same, enabling simultaneous operation at multiple workstations and improving efficiency.

[0050] Working principle:

[0051] Component clamping: The third power unit 10 of clamping structure III (second X-axis feed motor 101 / second Y-axis feed motor 102 / second Z-axis feed motor 103) drives the moving chamber 91 to the position of the component to be processed. The upper jaw 921 and lower jaw 922 of the clamping module 92 close to clamp the electronic component, and then move to the preset work station.

[0052] Lead positioning: The second power unit 6 of winding structure II drives the winding assembly 71 to move to the position corresponding to the component pin:

[0053] The first cylinder 744 controls the lower clamping plate 742 of the lead clamping module 74 to move downward, the upper clamping plate 741 separates from the lower clamping plate 742, and the second cylinder 745 drives the lead clamping module 74 to extend to the lead position.

[0054] The first cylinder 744 controls the lower clamp 742 to move upward and close to clamp the lead wire. Then the second cylinder 745 retracts, driving the lead wire to be stretched backward to the predetermined length.

[0055] Lead wire fixing: The third cylinder 754 controls the lower fixing block 752 of the lead wire fixing module 75 to open downwards, the winding assembly 71 moves upwards to place the end of the lead wire between the upper fixing block 751 and the lower fixing block 752, and the third cylinder 754 drives the lower fixing block 752 to move upwards and close, thus completing the lead wire fixing.

[0056] Winding operation: The guide rod 32 moves along the X-axis to the designated position under the drive of the first power unit 2. With the position adjustment of the clamping module 92 and the three-axis linkage of the winding assembly 71 (the first X-axis feed motor 61, the first Y-axis feed motor 62, and the first Z-axis feed motor 63 work together), the lead wire is wound to the component pin along the preset path, completing the complex winding process.
