Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component processing technology, and in particular to an automatic stripping device for flat coils. Background Technology
[0002] PFC inductors (Power Factor Correction inductors) are core components in power electronic devices such as charging piles. They are mainly used to optimize power utilization, reduce harmonic pollution, and improve system stability. A PFC inductor includes a magnetic core, winding posts, and coil (winding). Traditional designs typically use round coils, but these are gradually being replaced by flat coils. Flat coils offer advantages over round coils, including significantly reduced high-frequency losses, optimized heat dissipation and power density, enhanced mechanical stability and reliability, and reduced DC resistance. Therefore, they are better suited to the stringent efficiency and compactness requirements of infrastructure such as electric vehicle charging piles.
[0003] Flat coils are typically manufactured by the corresponding companies (also referred to as flat cables at the factory). For ease of storage and transportation, flat coils are covered with a soft outer sheath. Therefore, during the processing of PFC inductors, the outer sheath of the flat coil's connecting section needs to be removed. Traditionally, this is done manually, which is not only labor-intensive and inefficient, but also prone to excessive sheath removal, inconsistent work quality, and even damage to the internal copper foil.
[0004] There are existing automated devices for stripping flat coils, which can automatically complete the stripping process. However, they may still have defects such as being unsuitable for assembly line operations. Therefore, they are not well adapted to PFC inductor processing lines, resulting in low efficiency and low product quality, which requires further improvement. Utility Model Content

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.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] like Figures 1-6 As shown, an embodiment of this utility model provides an automatic stripping device for flat coils, including a first stripping component 10 and a second stripping component 20. The flat coil 30 has a rectangular cross-sectional profile, including two long sides (the width of the flat coil) and two short sides (the thickness of the flat coil), corresponding to the two front faces 31 and two side faces 32 of the area to be stripped of the flat coil 30. Therefore, the first stripping component 10 is used to strip the two front faces 31 of the flat coil 30, and the second stripping component 20 is used to strip the two side faces 32 of the flat coil 30, thereby ensuring that the area to be stripped of the flat coil 30 is fully and thoroughly stripped, allowing for reliable connection of the copper foil.
[0030] At the same time, such as Figure 2 , Figure 3As shown, the first peeling assembly 10 includes a first peeling seat 11, a first blade holder 12, a second blade holder 13, a first blade 14, a second blade 15, a first motor 16, and a second motor 17. The first peeling seat 11 is fixed, while the first blade holder 12 and the second blade holder 13 are movable relative to the first peeling seat 11. Specifically, the first peeling seat 11 is provided with a first drive module 18 and a second drive module 19. The first blade holder 12 is connected to the first drive module 18, which drives the first blade holder 12 to move relative to the first peeling seat 11. The second blade holder 13 is connected to the second drive module 19, which drives the second blade holder 13 to move relative to the first peeling seat 11. The first motor 16 and the second motor 17 are fixedly connected to the first tool holder 12 and the second tool holder 13, respectively. The first cutting tool 14 and the second cutting tool 15 are connected to the output end of the first motor 16 and the output end of the second motor 17, respectively, to maintain synchronous rotation (e.g., key connection with coupling).
[0031] The first stripping seat 11 is provided with an inlet 111 and an outlet 112. The flat coil 30 is in a straight state when it is not wound with the magnetic core. After continuous feeding by the corresponding feeding device, it is introduced into the first cutter seat 12 from the inlet 111 and then led out from the outlet 112. Therefore, the flat coil 30 continuously enters and passes through the first cutter seat 12. Generally speaking, whenever the flat coil 30 of the first preset length passes through the first stripping seat 11, the outer skin of the second preset length needs to be stripped. Subsequently, the flat coil 30 is cut into multiple segments of the first preset length for sequential winding with the magnetic core. Based on this, in this embodiment, the ends of the first cutter 14 and the second cutter 15 are aligned with the flat coil inside the first stripping seat 11. Thus, when stripping is required, the first drive module 18 and the second drive module 19 control the corresponding cutter seats to move until they contact the two front faces 31 of the flat coil 30, generating a certain pressure. The first cutter 14 is driven by the first motor 16 to rotate at high speed, and the second cutter 15 is driven by the second motor 17 to rotate at high speed. Therefore, the outer skin can be directly removed by the high-speed friction between the cutters and the flat coil 30.
[0032] It should be noted that in this embodiment, both the first drive module 18 and the second drive module 19 are arranged along the first direction R1, so that the first cutter 14 corresponds to one of the two front faces 31 of the flat coil 30, and the second cutter 15 corresponds to the other of the two front faces 31 of the flat coil 30. When both the first cutter 14 and the second cutter 15 need to contact or leave the flat coil 30, the first drive module 18 and the second drive module 19 drive the first cutter 14 and the second cutter 15 to move in opposite directions along the first direction, although the moving distance is not very large.
[0033] It should also be noted that the surfaces of the first peeling seat 11, the first knife seat 12, and the second knife seat 13 are all provided with working slots 113. The ends of the first knife 14 and the second knife 15 enter the interior of the first peeling seat 11 from the corresponding working slots 113, and the first knife 14 and the second knife 15 also have corresponding space when they move.
[0034] At the same time, such as Figures 4-5 As shown, the second peeling assembly 20 has a similar structure to the first peeling assembly 10, including a second peeling seat 21, a third blade holder 22, a fourth blade holder 23, a third blade 24, a fourth blade 25, a third motor 26, and a fourth motor 27. Similarly, the second peeling seat 21 is fixedly installed, while the third blade holder 22 and the fourth blade holder 23 are movably connected to it. The second peeling seat 21 is equipped with a third drive module 28 and a fourth drive module 29. The third blade holder 22 is connected to the third drive module, so that the third blade holder 22 can be driven to move relative to the second peeling seat 21 by the third drive module 28. The fourth blade holder 23 is connected to the fourth drive module 29, so that the fourth blade holder 23 can be driven to move relative to the second peeling seat 21 by the fourth drive module 29. The third motor 26 and the fourth motor 27 are fixedly connected to the third tool holder 22 and the fourth tool holder 23, respectively. The third cutter 24 and the fourth cutter 25 are connected to the output terminals of the third motor 26 and the fourth motor 27, respectively, and rotate synchronously. The third drive module 28 and the fourth drive module 29 are both arranged along the second direction, so that the third cutter 24 corresponds to one of the two sides 32 of the flat coil 30, and the fourth cutter corresponds to the other side 32 of the flat coil. The peeling method of the side 32 is similar to that of the front 31, and will not be described again here.
[0035] It is worth mentioning that the second stripping seat 21 is also provided with an inlet 111, an outlet 112, and a working slot 113. The line connecting the inlet 111 and the outlet 112 of the second stripping seat 21 (or the first stripping seat 11) is arranged along the third direction R3, that is, the flat coil 30 is continuously conveyed along the third direction R3. The distance between the second stripping seat 21 and the first stripping seat 11 (with the stripping position as a reference point) is set to a first preset distance, so that when the flat coil 30 in the first stripping seat 11 is stripped from the front 31, the previous segment of the flat coil 30 in the second stripping seat 21 has already completed the front 31 stripping, and then the side 32 stripping is performed.
[0036] In one specific embodiment, the first direction R1 is vertical, and the flat coil 30 is continuously conveyed with its two front faces 31 facing upwards and downwards. The second direction R2 and the third direction R3 are both horizontal, for example, the second direction R2 is transverse and the third direction R3 is longitudinal, which is the conveying direction of the flat coil 30. Of course, it can also be adjusted so that the first direction R1 is transverse and the second direction R2 is vertical, etc., and those skilled in the art can flexibly choose according to actual layout requirements.
[0037] In a preferred embodiment, the ends of the first cutter 14, the second cutter 15, the third cutter 24, and the fourth cutter 25 in this embodiment are all provided with cutter heads made of diamond. Diamond is a commonly used abrasive, so as a cutter head, it can effectively grind away the outer sheath of the flat coil under the drive of the corresponding motor at high speed.
[0038] It should be noted that the first drive module 18, the second drive module 19, the third drive module 28, and the fourth drive module 29 mentioned above can adopt forms commonly used in existing technologies, including but not limited to cylinders, lead screw mechanisms, electric actuators, etc., in conjunction with guide rail sliders for vertical and horizontal driving. Their specific structures have not been detailed above, and those skilled in the art can flexibly choose based on actual needs. Considering structural layout and precision control requirements, a more preferable method is to use cylinder drive in conjunction with guide rail slider guidance, such as... Figure 1 As shown.
[0039] In summary, the automatic flat coil stripping device provided in this embodiment, through the arrangement of the first stripping component 10 and the second stripping component 20, enables the two front faces 31 and two side faces 32 of the continuously conveyed flat coil 30 to be stripped thoroughly. Moreover, the overall structure is simple, the control is convenient and accurate, and it is suitable for assembly line operations, thereby improving the efficiency and quality of flat coil stripping and thus improving the quality of products such as PFC inductors.
[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
