A telescopic support inductor coil forming clamping device

Abstract

This utility model belongs to the technical field of inductor coil clamping devices, and discloses a telescopic support inductor coil forming clamping device. It aims to solve the problems of narrow applicability and cumbersome adjustment of existing devices. The device uses a rigid base plate as support and realizes the vertical height adjustment of the clamping structure through a telescopic component. It uses a servo motor to drive the gear and rack to mesh, driving the lifting inner core and upper structure to lift and lower precisely. The clamping function is completed by three sets of circumferentially symmetrically distributed clamping claws. Through another servo motor to drive the gear transmission system, the rotating disk is rotated, causing the motion slide in the track groove to push the radial motion block. Under the constraint of the limit structure, the clamping claws are synchronously extended and retracted radially, thus adapting to coil cores of different diameters. The device adopts fully electronic control adjustment, which can adapt to multi-specification production without replacing parts, improving the convenience of operation and production continuity. It is suitable for efficient forming and processing of diverse inductor coils.

Description

Technical Field

[0001] This utility model relates to the technical field of inductor coil clamping devices, specifically a telescopic support inductor coil forming clamping device. Background Technology

[0002] In the continuous development of the electronics manufacturing industry, inductors, as core components of electronic circuits, directly affect the performance and market acceptance of end products through their production quality and efficiency. Coil forming and clamping, as critical steps in the production process, play a decisive role in ensuring coil winding accuracy, turn count consistency, and core assembly stability, thus influencing the product's electrical performance and mechanical strength. As electronic devices continue to evolve towards miniaturization, integration, and multifunctionality, inductor specifications are becoming increasingly diversified. Different application scenarios have significantly different requirements for coil size and precision, posing even more stringent challenges to the adaptability of forming and clamping devices. Currently widely used inductor coil forming clamping devices suffer from significant structural rigidity. Most devices employ a fixed clamping jaw design, whose clamping range is strictly limited by the mechanical structure, allowing them to accommodate only one or a few coils of similar specifications. When the production line needs to switch product specifications, operators must disassemble the existing clamping device and replace it with the appropriate model of parts. This process is not only time-consuming but may also introduce errors due to recalibration, leading to fluctuations in product yield. Furthermore, it increases equipment maintenance costs and spare parts inventory pressure. Even if some devices possess certain adjustment functions, their operation is extremely cumbersome. These devices mostly rely on manual knobs or bolts for mechanical adjustment, requiring operators to repeatedly test the clamping force and range. This not only demands a high level of technical skill but also makes it difficult to guarantee adjustment accuracy. For example, when adjusting the clamping diameter, the position of each clamping jaw must be adjusted individually, and concentricity must be repeatedly calibrated. Even slight deviations can cause deformation of the coil or damage to the magnetic core during winding. Furthermore, manual adjustment methods are difficult to implement with digital control and cannot be integrated with the control systems of automated production lines, limiting the improvement of production intelligence. In mass production, this inefficient adjustment method also leads to decreased product consistency, further impacting the company's market competitiveness. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 This utility model provides a technical solution: A telescopic support inductor coil forming clamping device, comprising: First base plate 1, the first base plate 1 is a rigid planar plate structure; Telescopic component 2 is disposed on the first base plate 1. The telescopic component 2 includes an outer shell 3 and a lifting inner core 4. The outer shell 3 is fixedly connected to the first base plate 1, and the lifting inner core 4 is disposed inside the outer shell 3. The second base plate 5 is located above the outer shell 3 and is fixedly connected to the lifting inner core 4. The extension rod 6 is a hollow cylindrical structure. The extension rod 6 is set on the second base plate 5, and the second base plate 5 is fixedly connected to the extension rod 6. The clamping assembly 7 is located at the end of the extension rod 6. The clamping assembly 7 includes three sets of clamping claws 9, which are symmetrically distributed in a circular pattern. The three sets of clamping claws 9 can move inward or outward toward the center of the extension rod 6, and can clamp the annular inductor core, which is then convenient for winding wire on the core.

[0016] The clamping power assembly 8 is located inside the lifting inner core 4. The clamping power assembly 8 is used to drive the three sets of clamping claws 9 to move synchronously, and can control the degree of expansion or contraction of the three sets of clamping claws 9 to achieve clamping and fixing of magnetic cores of different diameters.

[0017] Furthermore, the telescopic assembly 2 also includes a rack 10, a first gear 11, and a first servo motor 12. The rack 10 is vertically arranged and fixedly connected to the inner wall of the outer shell 3. The first servo motor 12 is fixedly arranged inside the lifting inner core 4 and is coaxially fixedly connected to the first gear 11. The first servo motor 12 must be a servo motor capable of controlling rotation. The controller is provided by the motor supplier. When lifting is required, the first servo motor 12 drives the first gear 11 to rotate. Since the first gear 11 is meshed with the rack 10, it can drive the entire lifting inner core 4 and the second base plate 5 on it to move up and down relative to the outer shell 3. Controlling the rotation of the first servo motor 12 controls the lifting height. Using electronic control to control the lifting height provides high adjustment accuracy. For different types of magnetic cores, corresponding height data is used, avoiding the problem of repeated concentricity calibration after manual adjustment, resulting in high quality wound coils.

[0018] Furthermore, a rack groove 13 is provided on the lifting inner core 4 corresponding to the rack 10. One side of the rack 10 passes through the rack groove 13 and is placed inside the lifting inner core 4, and the rack 10 is meshed with the first gear 11.

[0019] Furthermore, a rotatable rotating disk 14 is provided inside the extension rod 6. Three sets of radial motion blocks 15 are provided on one side of the rotating disk 14, and the three sets of radial motion blocks 15 are fixedly connected to three sets of clamping claws 9 respectively. The rotation of the rotating disk 14 can drive the three sets of radial motion blocks 15 away from or towards the center of the circle.

[0020] Furthermore, the rotating disk 14 has three sets of track grooves 16, and a moving slide rod 17 is installed in each of the three sets of track grooves 16. The moving slide rod 17 is fixedly connected to the radial moving block 15. Since the moving slide rod 17 is stuck in the track groove 16, when the entire rotating disk 14 rotates (the moving slide rod 17 is restricted and cannot rotate with the rotating disk 14), the moving slide rod 17 will move with the track groove 16 in a direction away from or towards the center, thereby realizing the directional movement of the radial moving block 15.

[0021] Furthermore, a limiting block 18 is provided on the radial motion block 15. The limiting block 18 is a strip structure pointing towards the center of the extension rod 6. A limiting groove 19 corresponding to the limiting block 18 is opened in the extension rod 6, and the limiting block 18 is slidably engaged in the limiting groove 19. The main function of the limiting block 18 and the limiting groove 19 is to limit the movement direction of the radial motion block 15, so that it can only move along the diameter direction of the center of the extension rod 6.

[0022] Furthermore, the clamping power assembly 8 includes a rotating shaft 20, a second gear 21, a third gear 22, and a second servo motor 23. The rotating shaft 20 is located inside the extension rod 6 and is coaxially and fixedly connected to the rotating disk 14. The second gear 21 is located at the end of the rotating shaft 20 and is coaxially and fixedly connected. The second servo motor 23 is fixedly located inside the lifting inner core 4. The third gear 22 is coaxially connected to the second servo motor 23, and the second gear 21 and the third gear 22 are meshed together. The diameter of the second gear 21 is larger than the diameter of the third gear 22. The second servo motor 23 must be a servo motor capable of controlling rotation. The controller is provided by the motor supplier. The rotation of the second servo motor 23 will drive the rotating shaft 20 to rotate. The rotation speed can be reduced by the second gear 21 and the third gear 22, which can improve control accuracy. Since the movement of the clamping assembly 8 is controlled by a servo motor, different control data are recorded to correspond to different sizes of magnetic cores to be fixed. This allows for precise clamping and fixing of magnetic cores of different sizes, avoiding damage to the magnetic cores caused by excessive force during manual adjustment, and resulting in high-quality products.

They move radially under the drive of the rotating disk 14. Track groove 16: Three sets are opened on the rotating disk 14, and the internal part is equipped with a motion slide rod 17, which provides a motion trajectory for the motion slide rod 17 and drives the radial motion block 15 to move. Motion slide bar 17: It is set in the track groove 16 and fixedly connected to the radial motion block 15. It moves along the track groove 16 as the rotating disk 14 rotates, pushing the radial motion block 15. Limiting block 18: It is set on the radial motion block 15 and is a strip structure pointing to the center of the extension rod 6. It is slidably engaged in the limiting groove 19 to limit the movement direction of the radial motion block 15. Limiting groove 19: It is formed inside the extension rod 6 and corresponds to the limiting block 18. It allows the limiting block 18 to slide and engage, thus restricting the radial motion block 15 to move only along the diameter direction of the extension rod 6. Rotating shaft 20: It is set inside the extension rod 6 and is coaxially and fixedly connected to the rotating disk 14 and the second gear 21, transmitting the power of the clamping power assembly 8 to the rotating disk 14; The second gear 21 is located at the end of the rotating shaft 20 and is fixedly connected to it on the same axis. It meshes with the third gear 22 and has a larger diameter than the third gear 22 to achieve speed reduction and torque increase. The third gear 22 is coaxially connected to the second servo motor 23 and meshes with the second gear 21 to transmit the power of the second servo motor 23 to the second gear 21. The second servo motor 23 is fixed inside the lifting inner core 4 and coaxially connected with the third gear 22. It provides power for the movement of the gripper 9 and can precisely control the rotation.

[0024] Working principle: The entire device is based on the first base plate 1 as a rigid support. The telescopic component 2 above it is responsible for driving the entire clamping structure to achieve vertical lifting and lowering adjustment. Specifically, the outer shell 3 in the telescopic component 2 is fixedly connected to the first base plate 1. The inner wall of the outer shell 3 is provided with a vertical rack 10. The first servo motor 12 fixed inside the lifting inner core 4 is coaxially connected with the first gear 11. When the height needs to be adjusted, the first servo motor 12 drives the first gear 11 to rotate. Since the first gear 11 meshes with the rack 10, and the lifting inner core 4 is provided with a rack groove 13 corresponding to the rack 10 for the rack 10 to pass through, the lifting inner core 4 can drive the second base plate 5 and the upper structure fixedly connected to it to move up and down relative to the outer shell 3. By controlling the rotation parameters of the first servo motor 12, the lifting height can be precisely controlled to meet the requirements of clamping position height in different production scenarios. Meanwhile, the clamping function of the device is completed by the clamping assembly 7 and the clamping power assembly 8. The three sets of circumferentially symmetrically distributed clamping claws 9 of the clamping assembly 7 are set at the end of the extension rod 6. Their movement is driven by the clamping power assembly 8. The second servo motor 23 in the clamping power assembly 8 is fixed inside the lifting inner core 4. The third gear 22, which is coaxially connected to the second servo motor 23, meshes with the second gear 21 at the end of the rotating shaft 20. The diameter of the second gear 21 is larger than that of the third gear 22. The gear transmission realizes speed reduction and torque increase, improving control accuracy. When the second servo motor 23 is started, the power is transmitted to the rotating shaft 20 through the gear, driving the rotating disk 14 inside the extension rod 6 to rotate. The rotating disk 14 has openings on it. Three sets of track grooves 16, with moving slide rods 17 fixedly connected to radial moving blocks 15 within the grooves. The radial moving blocks 15 are in turn connected to three sets of clamping claws 9. Since the moving slide rods 17 cannot rotate synchronously with the rotating disk 14, they move along the track grooves 16 towards or away from the center when the disk 14 rotates. Simultaneously, the limiting blocks 18 on the radial moving blocks 15 slide and engage within the limiting grooves 19 of the extension rod 6, restricting the radial moving blocks 15 to move only along the diameter of the extension rod 6. This, in turn, drives the three sets of clamping claws 9 to move synchronously inward or outward towards the center, achieving stable clamping of annular inductor cores of different diameters, facilitating subsequent winding operations on the cores. Throughout the process, both clamping and lifting actions are electrically controlled by servo motors, eliminating the need to replace parts. Adjusting the corresponding parameters allows for adaptation to the production of products of different specifications, ensuring ease of operation and production continuity.
