Description

Technical Field

[0001] This utility model relates to the field of inductor processing equipment technology, and in particular to a flat wire common mode inductor lead-out mechanism. Background Technology

[0002] Common mode inductors typically contain two coils. When forming the wire ends of a flat wire common mode inductor, traditional wire-leading mechanisms can only perform wire-leading operations on one coil. To complete the wire-leading of both coils, it needs to be done in two separate operations. This is not only inefficient, but also prone to inconsistent wire-leading precision of the two coils due to positioning deviations between the two operations, thus affecting the quality of the common mode inductor. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a flat wire common mode inductor output mechanism, which solves the problem of low working efficiency in the past.

[0004] To address the aforementioned technical problems, this utility model discloses a flat-wire common-mode inductor lead-out mechanism, comprising a longitudinal guide rail extending along the longitudinal direction; a pair of clamping assemblies arranged symmetrically front and rear, including a front clamping assembly and a rear clamping assembly that can slide along the longitudinal guide rail, for clamping the two coils of the common-mode inductor; a pair of hooking blocks arranged symmetrically left and right, including a left hooking block and a right hooking block that can move laterally, respectively located on the left and right sides of the longitudinal guide rail, for lead-out of the coil ends; a pair of limiting blocks arranged symmetrically left and right, including a left limiting block and a right limiting block fixed to the bottom of the longitudinal guide rail, both arranged laterally, for limiting the pulled-out wire ends; and a pair of pressing mechanisms arranged symmetrically left and right, including a left pressing block and a right pressing block that can move longitudinally, for moving to the top surface of the coil, and cooperating with an external fixture to press the coil in the vertical direction.

[0005] The front clamping assembly includes two symmetrically arranged front clamping arms, each with a horizontally extending front clamping part at its bottom. The working end of each front clamping part has a first slot for inserting a coil. The rear clamping assembly includes two symmetrically arranged rear clamping arms, each with a horizontally extending rear clamping part. The working end of each rear clamping part has a second slot for inserting a coil. In the assembled state, the front clamping part is located directly below the corresponding limiting block, and a limiting gap is formed between the front clamping part and the corresponding limiting block for inserting the wire end, so as to help the wire end be parallel to the horizontal plane.

[0006] The left and right sides of the longitudinal guide rail are fixedly equipped with first longitudinal slide rails. Each first longitudinal slide rail is provided with a front longitudinal slider and a rear longitudinal slider that can slide along the first longitudinal slide rail. The front clamping arm is fixed to the front longitudinal slider, and the rear clamping arm is fixed to the rear longitudinal slider.

[0007] The front clamping assembly includes two front clamping cylinders, each of which is fixedly mounted on the longitudinal guide rail, and the telescopic rod of each front clamping cylinder is fixedly connected to the corresponding front longitudinal slider; the rear clamping assembly includes one rear clamping cylinder, which is fixedly mounted on the longitudinal guide rail, and the telescopic rod of the rear clamping cylinder is fixedly connected to each rear longitudinal slider.

[0008] This also includes a frame, with longitudinal guide rails fixedly mounted on the frame via gantry brackets.

[0009] The top surface of the frame is fixedly equipped with two symmetrically arranged left and right transverse slide rails. A left drive motor and a right drive motor are also fixedly installed on the top surface of the frame. The left transverse slide rail has a left transverse slider that slides with it. A left lead screw slider is fixedly connected to the top surface of the left transverse slider. A left lead screw body, which slides with the left lead screw slider, passes through the middle of the left lead screw body. A left driven wheel is fixedly connected to the end of the left lead screw body. A left driving wheel is located to the side of the left driven wheel. The left driven wheel and the left driving wheel are connected by a synchronous belt drive. The drive wheel is fixedly connected to the output shaft of the left drive motor, and the left hook block is fixedly connected to the left lead screw slider. The right transverse slide rail is provided with a right transverse slider that slides with the right transverse slide rail. The top surface of the right transverse slider is fixedly connected to the right lead screw slider. The middle part of the right lead screw slider is provided with a right lead screw body that slides with the right lead screw slider. The end of the right lead screw body is fixedly connected to the right driven wheel. The right driven wheel is provided on the side of the right driven wheel. The right driven wheel and the right driven wheel are connected by a synchronous belt drive. The right driven wheel is fixedly connected to the output shaft of the right drive motor, and the right hook block is fixedly connected to the right lead screw slider.

[0010] The working ends of the left and right hook blocks both extend downwards to form hook sections. The bottom surface of the hook section is flush with the top surface of the front clamping section, and the top surface of the hook section is flush with the bottom surface of the corresponding limiting block.

[0011] The left and right limit blocks are fixedly installed on the left and right sides of the longitudinal guide rail by mounting blocks, respectively, and both the left and right limit blocks are L-shaped.

[0012] The holding mechanism also includes a longitudinal slide table that drives the left and right pressing blocks to slide longitudinally.

[0013] The left limiting block has a left limiting groove for the insertion of the left pressing block end, and the right limiting block has a right limiting groove for the insertion of the right pressing block.

[0014] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0015] (1) By setting up a pair of clamping components that are symmetrically arranged front and back, the two coils of the common mode inductor can be stably clamped synchronously. With the lateral synchronous hooking action of the left hook block and the right hook block that are symmetrically arranged left and right, there is no need to separate the two coils for wire extraction in two separate operations as in traditional technology. The synchronous extraction of the wire ends of the two coils can be completed in a single operation, which greatly shortens the processing cycle of common mode inductor wire extraction and significantly improves the efficiency of mass production, solving the problem of low work efficiency in the past.

[0016] (2) Based on the longitudinal guide rail extending along the longitudinal direction, the clamping component can slide along the guide rail to achieve precise alignment, ensuring the consistency of the clamping position of the two coils in the longitudinal direction; the paired and symmetrical pressing mechanism can move along the longitudinal direction to the top surface of the coil, and cooperate with the external fixture to form vertical pressing and positioning, effectively limiting the movement of the coil in the vertical direction during the wire output process; the paired and symmetrical left limit block + right limit block are arranged in the transverse direction, which can limit the wire end in the transverse direction, and prevent the wire end from shifting laterally during the wire output process; through the multi-dimensional positioning coordination of longitudinal, vertical and transverse directions, the posture of the two coils is stable during the wire output process, the wire end forming consistency is high, and the defect rate caused by positioning deviation is effectively reduced.

[0017] (3) The clamping components, hook blocks, limit blocks and pressing mechanisms in the mechanism are all designed in pairs and are highly compatible with the structural characteristics of the symmetrical arrangement of the dual coils of the common mode inductor. They can be adapted to different specifications of flat wire common mode inductors without additional adjustment (only the component size needs to be finely adjusted). At the same time, the symmetrical structure can make the mechanism bear the force evenly, reduce the wear of components caused by uneven force on one side, extend the service life of the mechanism and improve the long-term operation stability.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model discloses a specific implementation of a flat wire common mode inductor output mechanism. Please see [link to implementation details]. Figure 1 The lead-out mechanism is used to synchronously lead out the two coils of a flat-wire common-mode inductor. The main structure of this mechanism includes a longitudinal guide rail 2, a clamping assembly, a hook block, a limiting block, and a pressing mechanism. The longitudinal guide rail 2 extends longitudinally, providing the mounting base and motion reference for the entire mechanism.

[0028] In this embodiment, the clamping assemblies are arranged in pairs and symmetrically front to back, including a front clamping assembly and a rear clamping assembly that can slide along the longitudinal guide rail 2, for stably clamping the two coils of the common-mode inductor. The front clamping assembly includes two symmetrically arranged front clamping arms 31, each with a front clamping portion 33 extending horizontally from its bottom. The working end of the front clamping portion 33 has a first slot 35 for inserting the coil. The rear clamping assembly includes two symmetrically arranged rear clamping arms 32, each with a rear clamping portion 34 extending horizontally. The working end of the rear clamping portion 34 has a second slot 36 for inserting the coil. In the assembled state, the front clamping portion 33 is located directly below the corresponding limiting block, and the two are precisely aligned in the vertical direction. A preset, narrow limiting gap is formed between the top surface of the front clamping portion 33 and the bottom surface of the limiting block. The height of this gap is slightly greater than the thickness of the flat line. Its function is to provide a horizontal channel for the line end when the hook block pulls the line end out, forcing the line end to move within the gap. This helps the line end remain parallel to the horizontal plane and effectively prevents the line end from sagging, curling up, or twisting due to its own weight or stress during the line exiting process.

[0029] Combination Figure 2 The longitudinal guide rail 2 has a first longitudinal slide rail 21 fixedly installed on its left and right sides. Each first longitudinal slide rail 21 is provided with a front longitudinal slider 22 and a rear longitudinal slider 23 that can slide along the first longitudinal slide rail 21. The front clamping arm 31 is fixed to the front longitudinal slider 22, and the rear clamping arm 32 is fixed to the rear longitudinal slider 23. The front clamping assembly also includes two front clamping cylinders 24, each of which is fixedly installed on the longitudinal guide rail 2. The telescopic rod of each front clamping cylinder 24 is fixedly connected to the corresponding front longitudinal slider 22. The rear clamping assembly includes a rear clamping cylinder 25, which is fixedly installed on the longitudinal guide rail 2. The telescopic rod of the rear clamping cylinder 25 is fixedly connected to each rear longitudinal slider 23. The mechanism also includes a frame 1, and the longitudinal guide rail 2 is fixedly mounted on the frame 1 via a gantry bracket 11.

[0030] Combination Figure 3The wire exit mechanism includes a wire hook assembly, which comprises two wire hook blocks arranged in pairs and symmetrically positioned left and right. These include a left wire hook block 51 and a right wire hook block 52, which are movable laterally and are respectively located on the left and right sides of the longitudinal guide rail 2 for wire exit from the coil. Two symmetrically positioned left and right transverse slide rails 53 and 52 are fixedly mounted on the top surface of the frame 1. A left drive motor 59 and a right drive motor are also fixedly mounted on the top surface of the frame 1. The left transverse slide rail 53 is provided with a left transverse slider 54 that slides with the left transverse slide rail 53. A left lead screw slider 55 is fixedly connected to the top surface of the left transverse slider 54. A left lead screw body 56 that slides with the left lead screw slider 55 is passed through the middle of the left lead screw slider 55. A left driven wheel 57 is fixedly connected to the end of the left lead screw body 56. A left driving wheel 58 is provided on the side of the left driven wheel 57. The left driven wheel 57 and the left driving wheel 58 are connected by a synchronous belt drive. The left driving wheel 58 is fixedly connected to the output shaft of the left drive motor 59. The left hook block 51 is fixed to the left lead screw slider 55. The right transverse slide rail is equipped with a right transverse slider that slides with it. A right lead screw slider is fixedly connected to the top surface of the right transverse slider. A right lead screw body that slides with the right lead screw slider passes through the middle of the right lead screw slider. A right driven wheel is fixedly connected to the end of the right lead screw body. A right driving wheel is located on the side of the right driven wheel. The right driven wheel and the right driving wheel are connected by a synchronous belt drive. The right driving wheel is fixedly connected to the output shaft of the right drive motor. The right hook block 52 is fixed to the right lead screw slider. The working ends of the left hook block 51 and the right hook block 52 both extend downwards to form hook portions 40. In terms of design, the bottom surface of the hook portion 40 is flush with the top surface of the front clamping portion 33, and the top surface of the hook portion 40 is flush with the bottom surface of the corresponding limiting block. This ingenious size design is crucial: when the hook block moves inward to hook the line end, its hooking part 40 can smoothly and without steps enter the limiting gap formed by the front clamping part 33 and the limiting block, ensuring the smoothness and accuracy of the hooking action and avoiding hooking failure or line end scratches caused by height difference.

[0031] Combination Figure 4 The limiting blocks are arranged in pairs and symmetrically, including a left limiting block 41 and a right limiting block 42 fixed to the bottom of the longitudinal guide rail 2. Both the left limiting block 41 and the right limiting block 42 are arranged laterally to limit the pulled-out wire ends. The left limiting block 41 and the right limiting block 42 are fixedly installed on the left and right sides of the longitudinal guide rail 2 by mounting blocks, respectively. Both the left limiting block 41 and the right limiting block 42 are L-shaped. The left limiting block 41 has a left limiting groove 43 for the end of the left pressure block 61 to be inserted, and the right limiting block 42 has a right limiting groove 44 for the right pressure block 62 to be inserted.

[0032] Combination Figure 5The clamping mechanism is arranged in pairs and symmetrically on the left and right, including a left clamping block 61 and a right clamping block 62 that can move longitudinally. These blocks are used to move to the top surface of the coil and, in conjunction with an external fixture, clamp the coil vertically. The clamping mechanism also includes a longitudinal slide 63 that drives the left clamping block 61 and the right clamping block 62 to slide longitudinally. It should be noted that the longitudinal slide 63 is a conventional moving mechanism, and its structure is similar to that of the drive hook block.

[0033] This mechanism synchronously clamps the two coils of a common-mode inductor using symmetrical clamping components, and, in conjunction with symmetrical hook blocks, achieves single-coil output of both coils, significantly improving work efficiency compared to the traditional method of outputting wire in two stages. Simultaneously, the limiting gap formed between the front clamping part 33 and the limiting block ensures that the wire end remains horizontal during output, preventing poor forming due to drooping or curling of the wire end. The transmission structure, consisting of a drive motor, synchronous belt, lead screw body, and lead screw slider, provides high-precision lateral movement control for the hook blocks, ensuring that the left and right hook blocks 52 complete the hooking action synchronously and smoothly, improving the consistency and accuracy of the output wire length. The L-shaped limiting block not only serves as a lateral limiter, but its limiting groove also cooperates with the pressing block of the pressing mechanism, providing guidance and positioning for the pressing block during pressing, preventing the pressing block from shifting during longitudinal movement, and ensuring that the pressing force is evenly applied to the top surface of the coil. The clamping mechanism and external fixture exert stable pressure on the coil in the vertical direction. Combined with the clamping assembly's gripping in the front-to-back direction, this achieves reliable multi-dimensional positioning of the coil, effectively counteracting the lateral tension generated during the coiling process and preventing displacement or deformation. The overall symmetrical structural design not only adapts to the dual-coil layout of common-mode inductors, improving the mechanism's versatility, but also ensures balanced force distribution, reducing unilateral wear and extending service life.

[0034] The operation of this mechanism is as follows: First, driven by the corresponding drive motors, the left hook block 51 and the right hook block 52 are brought together laterally inward through transmission components such as synchronous belts and lead screws, maintaining the initial closed state. At this time, the hook parts 40 of the two hook blocks are inside the longitudinal guide rail 2, reserving the corresponding inner position of the coil for subsequent inductor installation. Then, the flat wire common mode inductor to be processed is placed on the external fixture, ensuring that the two coils of the inductor correspond to the hook parts 40 of the left and right hook blocks 52 respectively, and the inner side of the coil is aligned with the hook parts 40 in the closed state. At this time, the downward protruding part of the hook part 40 is exactly inside the first coil at the top of the coil, only contacting the end of the first coil. Next, the front clamping cylinder 24 and the rear clamping cylinder 25 actuate, driving the front longitudinal slider 22 and the rear longitudinal slider 23 to slide along the first longitudinal slide rail 21, causing the front clamping arm 31 and the rear clamping arm 32 to move towards each other. The first slot 35 of the front clamping part 33 and the second slot 36 of the rear clamping part 34 respectively engage the front and rear ends of the two coils, completing the front-to-back clamping and fixing of the coils. Afterward, the longitudinal slide 63 of the pressing mechanism drives the left pressing block 61 and the right pressing block 62 to move forward longitudinally. The end of the left pressing block 61 is inserted into the left limiting groove 43 of the left limiting block 41, and the end of the right pressing block 62 is inserted into the right limiting groove 44 of the right limiting block 42. Under the guidance of the limiting grooves, the pressing blocks move smoothly to the top surface of the coil and apply appropriate pressure. Together with the external fixture, they form a stable pressing on the coil in the vertical direction, further restricting the coil's movement.

[0035] After positioning is completed, the left drive motor 59 and the right drive motor move in opposite directions, driving the left hook block 51 and the right hook block 52 to move laterally outward through the transmission components. Since the hook part 40 is pre-positioned inside the first loop at the top of the coil, and the thickness of the hook part 40 protrudes to match the width of the wire end, the hook part 40 will steadily hook the wire end of the first loop as it moves outward, pulling the wire end out of the coil. During the pulling process, the wire end naturally enters the limiting gap between the front clamping part 33 and the limiting block, and remains parallel to the horizontal plane under the constraint of the gap, avoiding twisting or deviation. When the wire end is pulled out to the preset length, the hook block stops moving outward and pauses briefly to ensure the wire end is stably formed. Subsequently, the hook block is driven by the drive motor to return to the initial closed state inward, and the longitudinal slide 63 of the pressing mechanism drives the pressing block to move backward, releasing the vertical pressing on the coil. Finally, the front clamping cylinder 24 and the rear clamping cylinder 25 move in opposite directions, and the front clamping arm 31 and the rear clamping arm 32 separate to the sides, releasing the coil. The operator or automated equipment can then remove the common mode inductor that has completed its output from the external fixture, and the next common mode inductor can be loaded and processed, starting the next output cycle.

[0036] Finally, it should be noted that the flat-wire common-mode inductor output mechanism disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
