Description

Technical Field

[0001] This utility model belongs to the field of inductor manufacturing technology, specifically relating to an inductor lead shaping device. Background Technology

[0002] Flat wire vertically wound inductors are widely used in high-frequency power supplies, new energy vehicle drive systems, and other fields with high requirements for inductor size and efficiency due to their excellent conductivity and space utilization. These inductors are typically wound with flat copper wire of rectangular cross-section, utilizing the skin effect of flat conductors to reduce AC losses.

[0003] Existing vertical winding processes require the conductor to be tightly wound perpendicular to the wide side of the flat wire, forming a multi-layered coil structure. Due to the rectangular cross-sectional characteristics of the flat copper wire, its lead portion can easily extend beyond the coil body in its untreated state, necessitating lead reshaping.

Detailed Implementation

[0026] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0027] Example 1:

[0028] like Figure 5 As an inductor coil, after winding and forming, the two inductor leads tend to bulge outwards, requiring reshaping of the inductor leads.

[0029] Provided such as Figure 1 The inductor lead shaping device shown includes a clamping cylinder 1 and clamping claws 2. Two clamping claws 2 are arranged opposite each other. The clamping claws 2 are mounted on the clamping cylinder 1. The clamping cylinder 1 is used to drive the clamping claws 2 to move relative to each other. A limit block 3 is provided between the two clamping claws 2.

[0030] The limiting block 3 is fixedly installed at the center of the clamping cylinder 1. A shaping cavity is formed between the clamping jaw 2 and the limiting block 3, which is used for shaping the inductor lead. The minimum distance between the clamping jaw 2 and the limiting block 3 is the same as the width of the inductor lead. The clamping cylinder 1 drives the clamping jaw 2 to move towards the center, and the inductor lead is shaped through the shaping cavity formed between the clamping jaw 2 and the limiting block 3.

[0031] It also includes a transmission assembly 4, which is fixedly connected to the clamping cylinder 1 and is used to drive the clamping cylinder 1 to move. The transmission assembly 4 includes a first cylinder 41 and a first connecting plate 42. The first connecting plate 42 is installed at one end of the first cylinder 41, and the clamping cylinder 1 is fixedly installed on the top surface of the first connecting plate 42. In one embodiment, the clamping cylinder 1 is fixedly connected to the first connecting plate 42 by screws. The first cylinder 41 drives the first connecting plate 42 to move, which in turn drives the clamping cylinder 1 and the gripper 2 to move, facilitating the forming of the inductor lead by the gripper 2 and the limiting block 3.

[0032] It also includes a lead wire fixing assembly 5, located at one end of the transmission assembly 4, used to fix the inductor lead so that the gripper 2 and the limiting block 3 can shape the inductor lead. The lead wire fixing assembly 5 includes a fixing base 51, a lead wire bracket 52, a second connecting plate 53, and a second cylinder 54. The lead wire bracket 52 passes through the fixing base 51, and its bottom is fixedly connected to the second connecting plate 53. The second connecting plate 53 is fixedly connected to the second cylinder 54. A pin 55 is provided on the top of the lead wire bracket 52. The second cylinder 54 drives the second connecting plate 53 to move, which in turn drives the lead wire bracket 52 to move. When the pin 55 moves upward, it passes through the coil and lifts the inductor lead, making it easier for the gripper 2 and the limiting block 3 to shape the inductor lead.

[0033] Working principle: The second cylinder 54 drives the second connecting plate 53 to move, which in turn drives the lead wire bracket 52 to move. When the ejector pin 55 moves upward, it passes through the coil and lifts the inductor lead. The first cylinder 41 drives the first connecting plate 42 to move, which in turn drives the clamping cylinder 1 and the clamping jaw 2 to move. The inductor lead is between the clamping jaw 2 and the limiting block 3. The clamping cylinder 1 drives the clamping jaw 2 to move towards the center, and the inductor lead is shaped through the shaping cavity formed between the clamping jaw 2 and the limiting block 3. The shaped inductor lead is as follows. Figure 6 As shown.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application 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 or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
