Description

Technical Field

[0001] This utility model relates to the field of inductor processing equipment technology, specifically to an ultra-thin inductor powder feeding device. Background Technology

[0002] An inductor is an electronic component that converts electrical energy into magnetic energy and stores it. It consists of a coil of wire. When current flows through the coil, it generates a magnetic field, thus storing energy. Inductors impede changes in current and are widely used in electronic circuits, such as for filtering, energy storage, and voltage transformation. Ultra-thin inductors are a special type of inductor, characterized by their small thickness, typically achieved through special design and manufacturing processes. While maintaining basic inductor performance, they can adapt to space-constrained applications, such as circuit boards in portable electronic devices like smartphones and tablets, contributing to the miniaturization and thinning of electronic devices.

[0003] Existing inductor production equipment uses a single-hole powder feeding device, which easily causes powder to clump together during powder delivery, resulting in uneven powder distribution. For ultra-thin inductors, this can lead to lower density around the product during molding and production, causing powder to fall off and abnormal product data when the product is touched even slightly during subsequent testing and use.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, in one embodiment, an ultra-thin inductor powder feeding device includes: a carrier component 1 and a switch component 2, wherein the carrier component 1 and the switch component 2 are detachably connected. The carrier component 1 has a sliding groove 12 at its bottom, while the switch component 2 has a corresponding convex groove 24 on its outer side. The inner contour of the sliding groove 12 and the outer contour of the convex groove 24 fit together, allowing the carrier component 1 and the switch component 2 to be snapped together to form a slide rail assembly.

[0030] It is understandable that when the switch body 2 slides back and forth at the bottom of the carrier body 1, it can control the opening and closing of the feeding channel, ensuring that the powder can be smoothly transported to the next pressurization process station after arriving at the carrier body 1.

[0031] Please continue reading the diagram. Figure 4 In this embodiment, the carrier component 1 is provided with a powder carrier cavity 11, so that the carrier component 1 can carry and transport powder through the powder carrier cavity 11; correspondingly, the switch component 2 is provided with a switch hole 21, so that the switch component 2 can control the opening and closing of the powder conveying channel through the switch hole 21.

[0032] It should be noted in detail that, in this embodiment, the powder carrier cavity 11 is inverted conical in shape. After the powder is conveyed into the powder carrier cavity 11, when the carrier component 1 and the switch component 2 are offset from each other, the powder conveying channel is closed, and the powder will gradually accumulate in the powder carrier cavity 11. Specifically, the cone angle of the powder carrier cavity 11 is 20°.

[0033] Furthermore, in this embodiment, the switch hole 21 includes a central hole 211 and multiple sets of surrounding holes 212. The central hole 211 and the surrounding holes are separated by connecting ribs, and the surrounding holes are formed around the central hole 211 to form a porous structure. This allows most of the powder to be conveyed through the central hole 211, while the remaining powder can be conveyed evenly from the surrounding holes, preventing powder accumulation and effectively improving the efficiency of powder conveying.

[0034] Specifically, the central hole 211 is circular with a diameter of 2.0 mm; correspondingly, the surrounding holes are square, and four sets of surrounding holes are symmetrically arranged. The connecting ribs are perpendicular to the inner end face of the surrounding holes, and four sets of connecting ribs are symmetrically arranged.

[0035] It is understandable that if the diameter of the center hole 211 is too large, the overall structural size will be too large, and the internal design space of the equipment will not be able to meet the requirements; while if the diameter of the center hole 211 is too small, the powder will easily accumulate and cannot fall off, resulting in channel blockage. The connecting rib can strengthen the connection between the center hole 211 and the surrounding hole, ensuring that there will be no processing failure when machining the center hole 211 and the surrounding hole on the switch body part 2.

[0036] It should be explained in detail that the top of the central hole 211 is formed with a first guide slope 22, while the top of the connecting rib is correspondingly formed with a second guide slope 23. The guide slope allows the powder to be separated and guided by the slope surface when it falls onto the switch body 2, passing through the central hole 211 and the surrounding hole respectively, ensuring smooth conveying of the powder.

[0037] Understandably, the angle of the guide slope needs to ensure the flowability of the powder while reducing processing difficulty. Specifically, the angle of the first guide slope 22 is 20°, the angle of the second guide slope 23 is 20°, and the width of the connecting rib is 0.5-0.7mm.

[0038] Working principle: The switch body 2 has flow holes (including a central hole 211 and symmetrically arranged surrounding holes). When the switch body 2 slides back and forth at the bottom of the carrier body 1, it can control the opening and closing of the feeding channel. After the powder is conveyed to the powder carrier cavity 11, when the carrier body 1 and the switch body 2 are staggered, the powder conveying channel is closed, and the powder will gradually accumulate in the powder carrier cavity 11. When the carrier body 1 and the switch body 2 are aligned, the powder conveying channel is opened. The guide slope allows the powder to be separated and guided by the slope surface when it falls onto the switch body 2, passing through the central hole 211 and the surrounding holes respectively.

[0039] Through the above technical solution, this application ensures that after the powder reaches the carrier part 1, it can be smoothly transported to the next pressurization process station, effectively solving the problem of powder agglomeration and ensuring that the powder is evenly distributed during the molding process.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
