Description

Technical Field

[0001] This utility model relates to the technical field of powder feeding, specifically to a feeding device for an AI computing chip inductor pressing molding machine. Background Technology

[0002] Inductors are core components in the AI ​​computing chip industry chain. Traditional ferrite inductors, due to their poor saturation characteristics and large size, can no longer meet high-performance requirements. Meanwhile, metal soft magnetic powder cores, with their advantages of high current tolerance, 40% smaller size, and low iron loss, have become the core choice for AI chip power supply modules. Current manufacturing processes for magnetic powder pressing often require precisely placing the powder into the small pores of the mold, and pre-feeding and leveling to reduce internal voids and ensure product yield. Therefore, the flexibility of the feeding device is crucial. However, in existing feeding methods, powdered materials are usually fed directly through funnels, aligning the feeding pipe with the mold position, and filling by piling or manually compacting with a scraper to complete one feeding cycle. Furthermore, the feeding platform corresponding to the mold is generally small, requiring multiple telescopic columns for support to ensure vertical pressure during pressing. This results in inconvenient repeated feeding, cumbersome manual monitoring and operation, and leads to low production efficiency and low product yield. If a scraper reciprocating motion is used to replace manual operation, then a suitable guide rail and other structures need to be designed to complete the automatic feeding operation without interfering with the mold pressing and forming. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a feeding device for an AI computing chip inductor pressing molding machine. This invention achieves automated, stable, and rapid feeding, eliminating the need for manual operation to level powder on the mold surface, thereby improving the finished product qualification rate. Furthermore, the limiting plate is movable without affecting the pressing action of the press punch.

[0004] The present invention discloses a feeding device for an AI computing chip inductor pressing molding machine, which includes an installation platform for placing a mold and a storage funnel for storing powder. The installation platform is provided with first guide rails on both sides corresponding to the placement opening of the mold. Limiting plates are slidably connected on the first guide rails. A scraping component is provided on one side of the installation platform corresponding to the lower part of the storage funnel.

[0005] The scraping assembly includes a scraper, a connecting rod, and a drive mechanism that are linked in sequence. The scraper has a feeding port and is connected to the storage funnel through a pipe. The two inner sides of the limiting plate form a second guide rail. The two sides of the scraper are adapted to the second guide rail. The drive mechanism drives the scraper to reciprocate back and forth on the mounting platform through the connecting rod. When the scraper moves backward away from the mold placement opening, the limiting plate moves backward along the first guide rail to one side of the mounting platform.

[0006] In one embodiment, the drive mechanism includes a servo motor fixed to one side and a third guide rail, on which a slider is slidably connected. The servo motor is used to control the slider to slide back and forth along the third guide rail.

[0007] In one embodiment, one end of the connecting rod is hinged to the slider, and the other end of the connecting rod is hinged to the scraper.

[0008] In one embodiment, a reset mechanism is also connected to the lower middle part of the connecting rod, the reset mechanism being used to reset the scraper to the rear edge of the mounting platform.

[0009] In one embodiment, the reset mechanism includes a first connector hinged to the middle of the connecting rod and a second connector hinged to the frame. An elastic member is connected between the first connector and the second connector, and the elastic member is in a vertical state when in a free state.

[0010] In one embodiment, a hemispherical first protrusion is provided at one end of the first guide rail away from the scraper assembly, and a first groove adapted to the first protrusion is provided on the limiting plate.

[0011] In one embodiment, the second guide rail has a hemispherical second protrusion at one end near the scraper assembly, and the scraper has second grooves on both sides that are adapted to the second protrusion.

[0012] In one embodiment, the installation platform is provided with a material collection port on the side near the scraper assembly, corresponding to the lower part of the limiting plate. The material collection port is connected to the storage funnel through a pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0014] This invention achieves automated feeding, which is stable and fast. No manual monitoring or operation is required to level the powder on the mold surface. The scraper's feeding and reciprocating motion evenly fills the mold with magnetic powder for making AI computing chip inductors, reducing internal empty space and thus improving the yield rate of press-formed products. Furthermore, during the pressing process, the limiting plate can move outward with the scraper, no longer obstructing the top of the mold. This facilitates the pressing action of the press punch in a smaller space and does not affect the synchronization and uniform pressure required for simultaneously manufacturing multiple chip inductors within the mold.

Detailed Implementation

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed 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; they can be described as the internal communication between 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. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown, the feeding device of the AI ​​computing chip inductor pressing molding machine of this utility model includes an installation platform 1 for placing the mold and a storage funnel 2 for storing powder. The installation platform 1 is provided with first guide rails 3 on both sides corresponding to the mold placement opening. A limit plate 4 is slidably connected on the first guide rails 3. A scraping component 5 is provided on one side of the installation platform 1 below the storage funnel 2.

[0022] The scraping assembly 5 includes a scraper 51, a connecting rod 52, and a drive mechanism 53 that are linked together in sequence. The scraper 51 has a feeding port and is connected to the storage hopper 2 through a pipe. The two inner sides of the limiting plate 4 form a second guide rail 41. The two sides of the scraper 51 are adapted to the second guide rail 41. The drive mechanism 53 drives the scraper 51 to reciprocate back and forth on the mounting platform 1 through the connecting rod 52. When the scraper 51 moves backward away from the mold placement port, the limiting plate 4 moves backward along the first guide rail 3 to one side of the mounting platform 1.

[0023] This invention achieves automated feeding operation, which is stable and fast. It can be directly added to the existing pressing and molding machine frame. Through the drive mechanism 53, the scraper 51 moves back and forth, and in conjunction with the feeding port, the magnetic powder material is automatically injected into the mold in the middle of the mounting platform 1. There is no need for manual monitoring and operation to sweep the powder off the mold surface. The reciprocating motion of the scraper 51 can evenly fill the mold with magnetic powder for making AI computing chip inductors, reducing the internal empty space and making the surface of the mounting platform 1 relatively flat, thereby facilitating and improving the pass rate of the pressed and molded products. In addition, the second guide rail 41 formed by the two limiting plates 4, in the limited space on the mounting platform 1, will directly block the mold, thus restricting the linear movement of the scraper 51, and will also affect the mold replacement or the up and down movement of the press punch. Therefore, during the pressing process, part of the limiting plate 4 can be moved horizontally along the first guide rail 3 to the outside of the mounting platform 1 as the scraper 51 moves backward, so that it no longer blocks the top of the mold. Each time the material is loaded, the scraper assembly 5 needs to control the scraper 51 to move forward until the limiting plate 4 returns to cover the top of the entire first guide rail 3. After that, the scraper 51 can be kept moving within the second guide rail 41. This facilitates mold replacement or the pressing action of the press punch, and no longer affects the punch synchronization and uniform pressure required when multiple chip inductors are made in the mold at the same time.

[0024] In one embodiment, to ensure proper motion control of the scraper 51, the drive mechanism 53 includes a servo motor 531 fixed to one side and a third guide rail 532. A slider 533 is slidably connected to the third guide rail 532. The servo motor 531 controls the slider 533 to slide back and forth along the third guide rail 532. This device uses the servo motor 531 to precisely control the movement distance of the slider 533, ensuring that the overall movement is linear in the front-back direction. One end of the connecting rod 52 is hinged to the slider 533, and the other end of the connecting rod 52 is hinged to the scraper 51. In this way, the connecting rod 52 controls the front-back movement of the scraper 51, so that the scraper 51 is kept in reciprocating motion between the second guide rail 41 on the mounting platform 1 during feeding and leveling, and has a certain degree of front-back elasticity to avoid increased friction of powder and damage to the connection of the scraper assembly 5. When it is necessary to change the mold or perform punch pressing operation, the drive mechanism 53 further controls the scraper 51 to continue moving to the rear side, bringing the limit plate 4 away from the mold placement opening. Each time it is reset, the scraper 51 must be moved to the front side to the end, bringing the limit plate 4 back to the mounting platform 1.

[0025] Furthermore, a reset mechanism 54 is connected to the lower middle part of the connecting rod 52. The reset mechanism 54 is used to reset the scraper 51 to the rear edge of the mounting platform 1. The reset mechanism 54 ensures that when the equipment is not in use, the scraper assembly 5 can be close to the frame, especially the scraper 51 and the limiting plate 4, which are generally on the mounting platform 1, to obtain a certain degree of protection. Specifically, the reset mechanism 54 includes a first connecting member 541 hinged to the middle part of the connecting rod 52 and a second connecting member 542 hinged to the frame. An elastic member 543 is connected between the first connecting member 541 and the second connecting member 542. The elastic member 543 is in a vertical state when in a free state. The connecting rod 52 is controlled by the aforementioned drive mechanism 53 to drive the scraper 51 to move back and forth. After the drive mechanism 53 stops working, the connecting rod 52 is no longer driven and is reset to the middle position by the elastic element 543. That is, the limiting plate 4 is located on the mounting platform 1 and completely covers the first guide rail 3. The scraper 51 is located on the rear edge of the mounting platform 1. Without frequent mold changes, it can be directly prepared for feeding and leveling operations.

[0026] In addition, such as Figure 3As shown, to ensure that the scraper 51 does not cause the limiting plate 4 to move when the second guide rail 41 moves, a hemispherical first protrusion 31 is provided at the end of the first guide rail 3 away from the scraper assembly 5, and a first groove adapted to the first protrusion 31 is provided on the limiting plate 4. Each time the drive mechanism 53 restores the position of the limiting plate 4, it will cause the scraper 51 to move forward to the top, so that the first protrusion 31 falls into the first groove on the limiting plate 4, giving the limiting plate 4 some resistance and locking it on the first guide rail 3. Similarly, to ensure that the limiting plate 4 returns to the mounting platform 1 first when the scraper 51 drives the limiting plate 4 to reciprocate, a hemispherical second protrusion 42 is provided at the end of the second guide rail 41 near the scraper assembly 5, and second grooves adapted to the second protrusion 42 are provided on both sides of the scraper 51. The second groove on the scraper 51 does not affect its reciprocating motion on the second guide rail 41. When it moves to the rear end of the second guide rail 41, the second protrusion 42 falls into the second groove. With the limiting at this end, the first groove of the limiting plate 4 disengages from the first protrusion 31, allowing it to continue to move rearward. During reset, the forward movement of the scraper 51 is resisted by the second groove and the second protrusion 42, which pushes the limiting plate 4 back onto the first guide rail 3 and engages with the first protrusion 31, allowing the scraper 51 to continue moving on the second guide rail 41. Alternatively, this limiting method can also use a latch or similar device to lock the position of the limiting plate 4 to suit actual production needs.

[0027] In one embodiment, a collection port 6 is provided on the side of the mounting platform 1 near the scraper assembly 5, below the limiting plate 4. The collection port 6 is connected to the storage funnel 2 via a pipe. The collection port 6 can recover the powder swept off by the scraper 51 when it moves on the second guide rail 41, preventing it from falling into the lower frame and causing waste or affecting the operation of other motors.
