Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, and in particular to a high-precision adjustable powder filling device for an integrally molded inductor. Background Technology

[0002] With the surge in demand for consumer electronics, the requirements for miniaturization and integration of internal components are becoming increasingly stringent. Molded inductors, with their excellent electrical performance and space advantages, are experiencing continuous market demand growth. Against this backdrop, inductor miniaturization manufacturing processes have become the focus of industry competition. The precision of magnetic powder filling directly affects the performance and stability of inductors. Magnetic powder filling requires uniformly filling high-permeability, low-loss magnetic powder into the mold cavity to ensure high-quality production of molded inductors and provide solid support for the performance upgrade of consumer electronics products.

[0003] A search revealed Chinese Patent Publication No. CN212032867U, which discloses a powder-filling machine for integrally molded inductors and its usage method. The machine includes a base plate, a movable plate, a top plate, and multiple guide pillars. The top ends of the guide pillars are fixedly connected to the top plate, and the bottom ends are fixedly connected to the base plate. The movable plate and the guide pillars are slidably connected. A powder dispensing device is connected to the top plate, and an offset device is connected to the movable plate. A mold is mounted on the offset device. The movable plate has a powder-filling position where the mold and the powder dispensing device contact each other. The powder dispensing device is used to fill the inductor with powder within the mold. This invention utilizes the vertical movement of the movable plate... During powder filling, the movable plate is moved to the powder filling position, and the mold on the movable plate can contact the powder dispensing device. The powder dispensing device fills the inductor in the mold with powder. After the powder filling is completed, the movable plate is moved down. This device can complete the powder filling quickly and efficiently. However, in actual use, the market has various requirements for the specifications and performance of integrally molded inductors. By selecting magnetic powders with different loose packing densities, inductor products that meet the needs of different customers can be produced. The internal space of the mold cannot be adjusted, and different powder filling molds need to be customized for magnetic powders with different loose packing densities. It is impossible to guarantee the consistency of the powder filling volume and meet the technical requirements of inductor production. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated molding inductor high-precision adjustable powder filling device, which aims to improve the problem that the internal space of the mold cannot be adjusted in the existing technology, and different filling molds are required for magnetic powders of different densities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated molded inductor high-precision adjustable powder filling device, comprising a powder filling plate, an installation strip fixedly connected to the top of the outer wall of the powder filling plate, an installation plate fixedly connected to the rear side of the outer wall of the powder filling plate, multiple powder filling ports opened on the top of the outer wall of the powder filling plate, multiple slots opened on the inner wall of the powder filling plate, a sliding plate slidably connected to the bottom of the inner wall of the powder filling plate, multiple blocks fixedly connected to the top of the sliding plate, a locking block fixedly connected to the left side of the outer wall of each of the multiple blocks, a screw rotatably connected to the left side of the inner wall of the powder filling plate, a knob fixedly connected to the left end of the screw, a through ruler fixedly connected to the right side of the sliding plate, and a powder scraping mechanism provided on the front side of the installation strip.

[0006] The above technical solution involves the installation strip and installation plate working together to securely install the powder-filling plate onto the external equipment, providing a stable foundation for the device's operation. When the operator turns the knob, the screw rotates accordingly, using threaded transmission to make the sliding plate slide linearly along the bottom of the inner wall of the powder-filling plate. The sliding plate drives the block and the locking block to move. The locking block can be embedded in the slot for positioning, preventing magnetic powder leakage when the sliding plate moves. Simultaneously, the through ruler moves synchronously with the sliding plate, and its top scale line, in conjunction with the starting plate, provides the operator with a precise displacement reference. By observing the scale values, the relative position of the block and the powder-filling port can be precisely adjusted, and the flow area of ​​the powder-filling port can be changed laterally, thereby achieving high-precision control of the magnetic powder filling amount.

[0007] As a further description of the above technical solution:

[0008] The powder scraping mechanism includes multiple demagnetizing springs, the rear ends of which are fixedly connected to the front side of the outer wall of the mounting strip, the front ends of which are fixedly connected to scrapers, the bottom of which are fixedly connected to multiple scraping teeth, an anti-sticking plate fixedly connected to the front side of the outer wall of the powder filling plate, the top of which has multiple toothed grooves, and a collection box slidably connected to the bottom of the outer wall of the powder filling plate.

[0009] The above technical solution involves fixing one end of a demagnetizing spring to an installation strip and connecting the other end to a scraper, providing elastic restoring force to the scraper and ensuring it fits tightly against the powder filling plate surface. The scraping teeth at the bottom of the scraper cooperate with the toothed grooves at the top of the anti-stick plate. When the scraper moves, the scraping teeth slide precisely along the toothed grooves, scraping away the magnetic powder around the powder filling port and the magnetic powder adhering to itself. The scraped magnetic powder is collected by the collection box at the bottom of the powder filling plate. The anti-stick plate prevents magnetic powder from adhering to the front of the powder filling plate, ensuring efficient completion of the powder scraping operation and maintaining a clean powder filling environment and powder filling accuracy.

[0010] As a further description of the above technical solution:

[0011] The powder scraping mechanism also includes two locking plates. The front side of the outer wall of the two locking plates is fixedly connected to the rear side of the outer wall of the collection box. Two locking holes are opened in the lower middle part of the mounting plate. Two rotating plates are rotatably connected to the lower middle part of the rear side of the mounting plate.

[0012] With the above technical solution: after the collection box slides into place, the locking plate on the rear side of its outer wall aligns with the locking hole of the mounting plate. Rotating the rotating plate will lock the locking plate, thus achieving a stable lock on the collection box. This ensures that the collection box does not shift during the powder scraping operation, guaranteeing the magnetic powder collection effect. After the operation is completed, rotating the rotating plate in the opposite direction will quickly unlock the collection box, facilitating disassembly and cleaning.

[0013] As a further description of the above technical solution:

[0014] The top of the through ruler is provided with scale lines, and a starting plate is fixedly connected to the right side of the outer wall of the through ruler.

[0015] The above technical solution uses the starting plate as a reference point for scale reading, which, together with the scale lines, provides operators with a precise quantitative reference. When the slide plate moves, the through ruler moves synchronously. By observing the relative values ​​between the scale lines and the fixed position of the powder filling plate, the movement distance of the slide plate can be accurately obtained, thereby achieving precise control of the powder filling amount and improving the accuracy and consistency of the powder filling operation.

[0016] As a further description of the above technical solution:

[0017] A limiting plate is fixedly connected to the outer wall of the screw, and the width of the powder filling port is the same as the width of the scraping teeth.

[0018] The above technical solution involves: limiting the rotation stroke of the screw by the limiting plate to prevent the slide from moving out of the working range and ensuring the safe operation of the device; and designing the powder filling port and scraper teeth to be of equal width so that the scraper teeth can completely cover the powder filling port. During the powder scraping operation, the residual magnetic powder around the powder filling port can be effectively cleaned, avoiding powder accumulation that affects the powder filling accuracy.

[0019] As a further description of the above technical solution:

[0020] The mounting plate has multiple screw holes on the upper middle part of the front side of its outer wall, and the mounting strip has multiple screws threaded onto its inner wall.

[0021] The above technical solution uses screw holes and screws to firmly connect the mounting plate and mounting strip, enhancing the stability of the device installation, ensuring the powder filling device remains stable during operation, and reducing errors caused by loose installation.

[0022] As a further description of the above technical solution:

[0023] The outer wall of each of the screws has a cross groove on the front side, and the top left and right sides of the outer wall of the powder filling plate have slide rails.

[0024] Through the above technical solutions: the cross-slot design of the screw facilitates disassembly and assembly using a conventional cross-screwdriver, reducing installation and maintenance difficulty and improving work efficiency; the slide rail provides a sliding track for the slider, and the slider guides the scraper to move smoothly in a predetermined direction, ensuring the accuracy and stability of the powder scraping action and improving the working reliability of the powder scraping mechanism.

[0025] As a further description of the above technical solution:

[0026] Both slide rails have sliders slidably connected to their inner walls, and the outer wall of the knob is treated with anti-slip material.

[0027] The above technical solution involves the slider and the slide rail working together to reduce the frictional resistance when the scraper slides, making its movement smoother and ensuring the continuity of the powder scraping operation. The anti-slip treatment on the outer wall of the knob increases the friction between the operator's hand and the knob, making it easier to apply force stably and achieve precise control of the knob's rotation, thereby accurately adjusting the amount of powder to be filled, improving the operating experience and powder filling accuracy.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the screw is driven by rotating the knob, and the slide plate is made to slide by the thread engagement. The slide plate drives the block and the locking block. The locking block and the locking groove cooperate to prevent powder leakage. The through ruler moves with the slide plate. The displacement of the slide plate is controlled by the scale line. By changing the relative position of the block and the powder filling port, the powder filling volume can be adjusted. It is suitable for the powder filling volume requirements of magnetic powder with different pine density.

[0030] 2. In this utility model, the cooperation between the scraping teeth at the bottom of the scraper and the toothed groove at the top of the anti-stick plate enables the scraping teeth to accurately scrape off the powder overflowing from the powder filling port and avoids self-adhesion, so that the excess powder is effectively collected and cleaned, avoiding affecting the subsequent powder filling accuracy and polluting the working environment, and improving the convenience and cleanliness of the device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] See attached document Figure 1 Appendix Figure 3 and attached Figure 4This utility model provides an embodiment of a high-precision adjustable powder filling device for an integrated molded inductor, comprising a powder filling plate 1, which serves as the main body of the device and provides an installation base and powder filling operation space for other components. An installation strip 3 is fixedly connected to the top of the outer wall of the powder filling plate 1 to securely install the powder filling plate 1 onto an installation plate 4, ensuring the stability of the device during operation. An installation plate 4 is fixedly connected to the rear side of the outer wall of the powder filling plate 1 to further enhance the installation firmness and overall structural strength of the device. Multiple powder filling ports 5 are provided on the top of the outer wall of the powder filling plate 1 for the falling and filling of magnetic powder, realizing the powder filling operation for the integrated molded inductor. Multiple slots 6 are provided on the inner wall of the powder filling plate 1, which cooperate with locking blocks 9 to provide positioning and guidance for the movement of a sliding plate 7, ensuring the accuracy of the sliding plate 7's movement. A sliding plate 7 is slidably connected to the bottom of the inner wall of the powder filling plate 1, and the powder filling amount is adjusted by its sliding, realizing the adjustable function of the powder filling volume. The top of the sliding plate 7 is fixedly connected to... Multiple blocks 8 move with the slide plate 7, changing their relative position to the powder filling port 5, thereby controlling the flow area of ​​the powder filling port 5. Each block 8 has a locking block 9 fixedly connected to its outer left side, which can be locked into the locking groove 6 on the inner wall of the powder filling plate 1 to achieve precise locking of the sliding plate 7 and prevent magnetic powder leakage. The inner left side of the powder filling plate 1 is rotatably connected to a screw 10, which is threadedly engaged with the slide plate 7 to convert its own rotation into linear sliding of the slide plate 7. The left end of the screw 10 is fixedly connected to a knob 11, which is convenient for the operator to manually drive the screw 10 to rotate and adjust the amount of powder filling. The right side of the slide plate 7 is fixedly connected to a through ruler 12, which moves synchronously with the slide plate 7. The scale line 13 set on its top serves as a capacity reference. By observing the relative scale value between the scale line 13 and the fixed position on the powder filling plate 1, the operator can accurately grasp the moving distance of the slide plate 7 and thus accurately control the amount of powder filling. A powder scraping mechanism 2 is set on the front side of the mounting strip 3.

[0040] Specifically, the powder filling plate 1 is first fixed to the equipment using the mounting strip 3 and mounting plate 4. During adjustment, the operator rotates the knob 11, causing the screw 10 to rotate on the left side of the inner wall of the powder filling plate 1. Utilizing the threaded engagement between the screw 10 and the slide plate 7, the slide plate 7 slides linearly along the bottom of the inner wall of the powder filling plate 1. As the slide plate 7 moves, the top square 8 and the locking block 9 move synchronously. The locking block 9 engages with the slot 6 on the inner wall of the powder filling plate 1, thus positioning the slide plate 7 and preventing magnetic powder leakage. Simultaneously, the through ruler 12 fixed to the right side of the slide plate 7 moves with the slide plate 7. The relative value between the top scale line 13 and the fixed position of the powder filling plate 1 can intuitively display the moving distance of the slide plate 7. The movement of the slide plate 7 changes the relative position of the block 8 and the powder filling port 5. The block 8 horizontally blocks the powder filling port 5, adjusting the magnetic powder holding volume. When it is necessary to increase the amount of powder, turn the knob 11 counterclockwise, and the screw 10 drives the slide plate 7 to move to the left, and the block 8 reduces the blocking area of ​​the powder filling port 5. Conversely, turn the knob 11 clockwise, and the slide plate 7 moves to the right, and the block 8 increases the blocking area, thereby precisely controlling the amount of magnetic powder falling through the powder filling port 5.

[0041] See attached document Figure 1 Appendix Figure 3 and attached Figure 5 The powder scraping mechanism 2 includes multiple demagnetizing springs 201, which provide elastic restoring force for the scraper 202, ensuring that the scraper 202 can automatically return to its original position after the powder scraping operation. The rear ends of the multiple demagnetizing springs 201 are fixedly connected to the front side of the outer wall of the mounting strip 3 to securely install the demagnetizing springs 201 and ensure the stability of their elastic action. The front ends of the multiple demagnetizing springs 201 are fixedly connected to the scraper 202, which moves back and forth under the action of the demagnetizing springs 201 to complete the powder scraping operation. The bottom of the multiple scraper 202 is fixedly connected to multiple scraping teeth 203, which cooperate with the tooth grooves 205 to effectively scrape away the powder around the powder filling port 5 and the powder adhering to itself. The front side of the outer wall of the powder filling plate 1 is fixedly connected to an anti-sticking plate 204 to prevent powder from adhering to the front surface of the powder filling plate 1, making it easy to scrape and clean. The top of the anti-sticking plate 204 has multiple tooth grooves 205. 05. The scraper tooth 203 is provided with a sliding guide to ensure the accuracy of the scraping path. The bottom of the outer wall of the powder filling plate 1 is slidably connected to the collection box 206, which is used to collect the scraped powder and avoid powder accumulation and contamination. The scraping mechanism 2 also includes two locking plates 207, which are used to cooperate with the locking holes 208 and the rotating plate 209 to realize the locking and unlocking of the collection box 206. The front side of the outer wall of the two locking plates 207 is fixedly connected to the rear side of the outer wall of the collection box 206, providing a connection basis for locking the collection box 206. The lower middle part of the mounting plate 4 has two locking holes 208, which cooperate with the locking plates 207 and the rotating plate 209 to realize the fixed limit of the collection box 206. The lower middle part of the rear side of the outer wall of the mounting plate 4 is rotatably connected to two rotating plates 209. By rotating to lock or release the locking plates 207, the locking and unlocking operations of the collection box 206 can be realized.

[0042] Specifically, after the powder filling operation is completed, the operator pushes the collection box 206 to slide along the bottom of the outer wall of the powder filling plate 1, so that the locking plate 207 on the rear side of the outer wall of the collection box 206 is aligned with the locking hole 208 of the mounting plate 4. The rotating plate 209 on the rear side of the mounting plate 4 is rotated to lock the locking plate 207 and fix the collection box 206. Then, the scraper 202 is manually pushed forward. The scraping teeth 203 at the bottom of the scraper 202 slide along the top tooth groove 205 of the anti-stick plate 204 to scrape off the sticky powder and scrape the scattered powder into the collection box 206. The powder scraping operation is completed. The scraper 202 returns to its original position under the elastic action of the demagnetizing spring 201. Finally, the rotating plate 209 is rotated in the opposite direction to release the lock on the collection box 206 and pull it out from the bottom of the outer wall of the powder filling plate 1, completing the unified collection and processing of powder. Through the orderly cooperation of various components, the cleaning and collection of excess powder is achieved, ensuring the powder filling accuracy and the cleanliness of the working environment.

[0043] See attached document Figure 2 Appendix Figure 3 and attached Figure 5A starting plate 14 is fixedly connected to the right side of the outer wall of the through ruler 12, serving as the starting reference point for scale reading. This facilitates precise determination of the initial position of the through ruler 12, thereby accurately measuring the movement distance of the slide plate 7. A limit plate 15 is fixedly connected to the outer wall of the screw 10, limiting the rotation stroke of the screw 10 and preventing the screw 10 from moving laterally out of its normal working range. The width of the powder filling port 5 is the same as the width of the scraper teeth 203, ensuring that the scraper teeth 203 can completely cover the powder filling port 5, effectively cleaning excess powder around the powder filling port 5 during scraping. Multiple screw holes 16 are provided on the upper middle part of the front side of the outer wall of the mounting plate 4, for use with screws 17 to achieve a stable connection between the mounting plate 4 and the mounting strip 3, enhancing the overall structural strength of the device. Multiple screws 17 are threaded onto the inner wall of the mounting strip 3, which securely connect the mounting strip 3 and the mounting plate 4, ensuring the filling... To ensure the stability of the powder plate 1 installation, the outer walls of multiple screws 17 are provided with cross grooves 18, which facilitate the tightening and loosening of screws 17 using a Phillips screwdriver, improving installation and maintenance efficiency. The top left and right sides of the outer wall of the powder plate 1 are provided with slide rails 19, which provide sliding tracks for the slider 20 and guide the scraper 202 to move smoothly in a predetermined direction. The inner walls of the two slide rails 19 are slidably connected to the sliders 20, which cooperate with the slide rails 19 to realize the sliding guidance and support of the scraper 202, ensuring the stability of the powder scraping operation. The tops of the two sliders 20 are respectively fixed to the bottom left and right sides of the scraper 202, connecting the scraper 202 to the slide rails 19, so that the scraper 202 can slide along the slide rails 19. The outer wall of the knob 11 is treated with anti-slip material to increase the friction between the operator's hand and the knob 11, making it easier to rotate the knob 11 more stably and achieve precise adjustment of the powder filling amount.

[0044] Specifically, the starting plate 14, in conjunction with the scale line 13, provides a precise reference for measuring the moving distance of the slide plate 7. Combined with the drive structure of the screw 10 and the knob 11, it enables fine adjustment of the powder filling amount. The limit plate 15 prevents the screw 10 from rotating excessively, ensuring that the slide plate 7 operates within a safe working range. The equal width design of the powder filling port 5 and the scraper tooth 203 ensures that excess powder is effectively cleaned and maintains the powder filling accuracy. The screw hole 16 of the mounting plate 4, the screw 17 of the mounting strip 3, and the cross groove 18 design enable a stable connection between the device and external equipment and convenient disassembly and assembly. The anti-slip treatment of the knob 11 further improves the operational stability and adjustment accuracy.

[0045] Working principle: The powder filling plate 1 is securely installed on the equipment via the mounting strip 3 and mounting plate 4. When the powder filling volume needs to be adjusted, the operator turns the knob 11. The knob 11 drives the screw 10 to rotate on the left side of the inner wall of the powder filling plate 1. Since the screw 10 and the slide plate 7 have a threaded engagement, the rotation of the screw 10 is converted into the linear sliding of the slide plate 7 on the bottom of the inner wall of the powder filling plate 1. During the movement of the slide plate 7, the block 8 and the locking block 9 fixed on its top move accordingly. The locking block 9 can engage with the locking groove 6 on the inner wall of the powder filling plate 1 to prevent magnetic powder leakage. At the same time as the slide plate 7 moves, the through ruler 12 fixed on its right side moves synchronously. The scale line 13 on the top of the through ruler 12 serves as a capacity reference. By observing the relative scale values ​​of the scale line 13 and the fixed position on the powder filling plate 1, the operator can determine the moving distance of the slide plate 7. The movement of the slide plate 7 will change the relative position of the block 8 above it and the powder filling port 5. The block 8 can block the powder filling port 5 from left to right, horizontally encroaching on the volume of magnetic powder, thereby controlling the amount of magnetic powder falling through the powder filling port 5. When it is necessary to increase the powder filling volume, turn the knob 11 counterclockwise, and the screw 10 will drive the slide plate 7 to move to the left. The area of ​​the block 8 blocking the powder filling port 5 will decrease, and more powder can fall through the powder filling port 5. Conversely, turn the knob 11 clockwise, and the slide plate 7 will move to the right. The area of ​​the block 8 will increase, and the amount of powder filling will decrease accordingly.

[0046] Furthermore, after the powder filling operation is completed, the operator pushes the collection box 206 to slide it at the bottom of the outer wall of the powder filling plate 1. The locking plate 207 fixed on the rear side of the outer wall of the collection box 206 corresponds to the locking hole 208 on the mounting plate 4. At this time, the rotating plate 209 on the rear side of the outer wall of the mounting plate 4 is rotated. After the rotating plate 209 rotates, it locks the locking plate 207, thus firmly locking the collection box 206 in the working position. Then, the scraper 202 is pushed forward. The scraping teeth 203 at the bottom of the scraper 202 cooperate with the tooth groove 205 at the top of the anti-stick plate 204. When the scraper 202... When the scraper moves to the front of the powder filling plate 1, the scraper teeth 203 slide along the tooth groove 205 to scrape off the powder adhering to the scraper teeth 203. The scraper teeth 203 scrape the scattered powder into the collection box 206 to avoid the accumulation of powder affecting the subsequent powder filling accuracy and to prevent the powder from contaminating the working environment. After the powder scraping operation is completed, the scraper 202 moves backward and resets under the elastic action of the demagnetizing spring 201. Then, the rotating plate 209 is rotated in the opposite direction to unlock the collection box 206. The collection box 206 is then pulled out from the bottom of the outer wall of the powder filling plate 1, and the collected powder can be processed uniformly.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
