Since the coil of the one-piece molded inductor is completely wrapped and encapsulated by soft magnetic powder material, it has a shielding effect and stability that cannot be matched by traditional wound inductors.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference Figures 1 to 5 According to the static quantitative powder feeding device of the first embodiment of the utility model, it includes a frame 100, a silo 200, a quantitative mechanism 300, a driving device 400 and a powder feeding mechanism 500. The silo 200 is fixedly connected to the frame 100. The silo 200 has a material cavity 210 for accommodating materials, and the bottom of the silo 200 has a discharge port 220. The quantitative mechanism 300 is arranged on the frame 100 and is located at the bottom of the silo 200. The quantitative mechanism 300 can quantitatively receive powder from the discharge port 220. The driving device 400 is arranged on the frame 100. The powder feeding mechanism 500 is arranged on the frame 100 and is transmission-connected with the driving device 400. The powder feeding mechanism 500 can receive powder from the quantitative mechanism 300. The driving device 400 can drive the powder feeding mechanism 500 to reciprocate between the quantitative mechanism 300 and the target position. By fixing the silo 200 on the frame 100, the silo 200 can be prevented from shaking and stratifying during movement. The quantitative mechanism 300 can receive materials under the static silo 200 with more accurate quantitative measurement. Then, the accurately quantitative powder material is delivered to the target position through the feeding mechanism for subsequent powder filling process, so that the subsequent powder filling amount can also be more accurate, thereby improving the quality of the inductor.

[0033] Specifically, the frame 100 is used to carry components, and the silo 200 is fixedly connected to the frame 100. The specific shape of the silo 200 is not limited. The silo 200 has a material chamber 210 for storing powder. It can be understood that the material in the silo 200 can be added from the outside to maintain a continuous supply of powder. After the silo 200 is fixedly connected to the frame 100, the density of the powder stored inside is basically the same. It can be understood that the powder can be stirred and mixed before adding into the material chamber 210. Since the powder is mixed more evenly, the density of the powder at each position in the material chamber 210 is basically the same. Compared with the prior art, the powder stored in the static silo 200 will not shake and stratify, which can facilitate subsequent quantitative measurement. The quantitative mechanism 300 can receive the powder from the discharge port 220 of the silo 200. The quantitative mechanism 300 can be used according to the user. The powder is quantitatively received according to the set amount required by the user. It can be understood that the volume quantitative method is generally adopted. The above method is relatively easy to implement and is also a commonly used technical means. Therefore, since the material density in the silo 200 is consistent, the quality of the powder quantitatively measured by the quantitative mechanism 300 each time can be consistent, and there will be no obvious difference in multiple quantitative measurements. After the quantitative mechanism 300 achieves quantitative measurement, the feeding mechanism can receive the powder from the quantitative mechanism 300. During the production of inductors, the coil needs to be placed in the mold and then filled with powder. Therefore, the powder feeding mechanism 500 can be used to transport the powder to the corresponding position of the mold where the coil is placed for powder filling. The powder feeding mechanism 500 has completed quantitative measurement during reciprocating motion, and the silo 200 will not shake and stratify in the prior art, so that the powder is accurately quantified, thereby improving the yield rate of inductor production.

[0034] Reference Figures 2 to 5 In some embodiments of the present invention, the quantitative mechanism 300 includes a quantitative plate 310 and a control mechanism 320. The quantitative plate 310 is provided with at least one quantitative powder cavity 311. The control mechanism 320 is connected to the quantitative plate 310. The control mechanism 320 can control the communication time between the quantitative powder cavity 311 and the discharge port 220 to adjust the amount of powder received. Through the above structure, quantitative powder can be easily achieved with high production efficiency.

[0035] Specifically, the quantitative plate 310 can be set to a corresponding thickness as required to provide different depths of the quantitative powder holes 311 to meet different quantitative requirements. The number and position of the quantitative powder holes 311 can be set according to the mold where the coil is placed. In order to improve production efficiency, the quantitative powder holes 311 can be set into multiple rows, and multiple quantitative powder holes 311 are set at intervals in each row. The discharge port 220 can be an overall discharge port 220, which can cover all quantitative powder holes 311, or it can be set in a form corresponding to the number and position of the quantitative powder holes 311. It only needs to be able to discharge the material. The control mechanism 320 can control the connection time between the quantitative plate 310 and the discharge port 220. It can be understood that the powder falls by gravity, and the material falling into each quantitative powder hole 311 per unit time is basically the same. By controlling the connection time, the powder amount can be adjusted. When the powder amount demand is large, the connection time can be extended. When the powder amount demand is small, the connection time can be shortened. The quantitative powder can be simply realized with high production efficiency.

[0036] Reference Figures 2 to 3 In some embodiments of the present utility model, the frame 100 includes a first plate 110, the silo 200 is arranged on the first plate 110, the quantitative plate 310 is slidably arranged between the silo 200 and the first plate 110, the first plate 110 is provided with a first through hole 111 which can correspond to the quantitative powder cavity 311 one by one, and the control mechanism 320 includes a first linear driving component 321, the first linear driving component 321 is transmission-connected with the quantitative plate 310, and the first linear driving component 321 can drive the quantitative plate 310 to slide to a first position and a second position, in the first position, the quantitative powder cavity 311 is connected to the discharge port 220 and is not connected to the first through hole 111, and in the second position, the quantitative powder cavity 311 is connected to the first through hole 111 and is not connected to the discharge port 220. The quantitative quantity can be controlled by the first linear driving component 321, the structure is simple, and the quantitative transfer of powder can be realized by the cooperation between the quantitative plate 310 and the first plate 110 of the silo 200, and the structure is ingenious and simple.

[0037] Specifically, the silo 200 can be connected to the top of the first plate 110 by fasteners, and the quantitative plate 310 can be arranged between the bottom of the silo 200 and the first plate 110. It can be understood that a groove for accommodating the quantitative plate 310 can be arranged at the bottom of the silo 200 so that the quantitative plate 310 can slide in the groove, and the discharge port 220 of the silo 200 is located above the quantitative plate 310. The first linear drive component 321 can be set as a cylinder, and the rod of the cylinder can be connected to the quantitative plate 310. The cylinder can The quantitative plate 310 can be driven to slide back and forth linearly, and the first through hole 111 can be set on the first plate 110. The relative position relationship of each first through hole 111 is consistent with the relative position relationship of each quantitative powder hole 311. The discharge port 220 and the first through hole 111 can be staggered with each other, and the quantitative plate 310 located between the two can be movably connected to the silo 200 or the first through hole 111. During specific use, the quantitative plate 310 can be driven to slide to the first position and the second position by the first linear driving component 321, and the discharge port 220 and the first through hole 111 can be staggered with each other. The material port 220 is not connected to the quantitative powder hole 311 of the quantitative plate 310 at the initial position. When the first linear driving component 321 drives the quantitative plate 310 to the first position, the material outlet 220 is connected to the quantitative powder hole 311, and the quantitative powder hole 311 is not connected to the first through hole 111. The driving time of the first linear driving component 321 can be controlled to make the material outlet 220 drop a quantitative amount of powder into the quantitative powder hole 311. The first position can be regarded as the quantitative position. After the quantitative is completed, the first linear driving component 321 drives the quantitative powder hole 311 to move the material outlet 220 to the quantitative powder hole 311. The quantitative powder hole 311 of the measuring plate 310 can stop receiving powder when it is offset from the discharge port 220, and when driven to the second position, the quantitative powder hole 311 of the quantitative plate 310 can be connected with the first through hole 111 but not with the discharge port 220. At this time, the quantitatively measured powder can fall from the first through hole 111 to the feeding mechanism, and the quantitative amount can be controlled by the first linear driving component 321. The structure is simple, and the quantitative transfer of powder can be achieved through the cooperation between the quantitative plate 310 and the first plate 110 of the silo 200. The structure is ingenious and simple.

[0038] It should be noted that the first linear driving component 321 is not limited to the above embodiment, and other embodiments may also be adopted. For example, the first linear driving component 321 may also be an electric telescopic rod.

[0039] It is understandable that the first linear driving component 321 may also be a rotation driving component, which can drive the quantitative plate 310 to rotate until it is docked with the first plate 110.

[0040] Reference Figures 1 to 5In some embodiments of the present invention, the silo 200 includes a housing 230 and a discharge plate 240. The housing 230 has an opening facing downward. The discharge plate 240 is detachably arranged on the first plate 110, and the housing 230 is installed on the top of the discharge plate 240 to form a material cavity 210. The discharge plate 240 is provided with a discharge port 220, and the discharge port 220 can correspond to the quantitative powder hole 311 one by one. The one-to-one corresponding discharge ports 220 can be easily dislocated, and even if the quantitative plate 310 moves at least one hole, the dislocation can stop the material discharge, which can reduce the activity stroke of the first linear drive component 321, and the discharge plate 240 can be replaced according to the specifications of the production mold, and has strong versatility.

[0041] Specifically, the shell 230 can be a square sheet metal part, and the opening of the shell 230 is installed toward the discharge plate 240. A material cavity 210 is formed between the shell 230 and the discharge plate 240. The discharge port 220 on the discharge plate 240 can lead out the powder in the material cavity 210, and the discharge ports 220 with the same number and relative position as the quantitative powder holes 311 can be set, so that the discharge ports 220 and the quantitative powder holes 311 can correspond one-to-one, so that the first linear drive component 321 can drive the quantitative plate 310 to the quantitative powder holes 311 can correspond one-to-one with the discharge ports 220 to achieve powder quantification, and the one-to-one corresponding discharge ports 220 can be easy to dislocate, even if the quantitative plate 310 moves at least one hole position, it can dislocate to stop unloading, which can reduce the activity stroke of the first linear drive component 321, and the discharge plate 240 can be replaced according to the specifications of the production mold, with strong versatility.

[0043] Specifically, the powder receiving component 510 is located below the quantitative mechanism 300 and can receive the quantitative powder from the quantitative mechanism 300. The switch component 520 can control whether the powder receiving component 510 drops powder or not. During specific use, the powder receiving component 510 is driven by the driving device 400 to move between the quantitative mechanism 300 and the target position of the product to be processed. During specific use, when the capacity of the quantitative powder hole 311 of the quantitative plate 310 is insufficient, powder can be filled multiple times by stacking it. This can be achieved by feeding the material to the driving feeding mechanism multiple times through the driving device 400. The switch component 520 on the feeding mechanism can control the powder filling switch. When receiving powder, the switch component 520 is closed. When the driving device 400 drives the feeding mechanism to the target position, the switch component 520 can be opened to enable the powder feeding mechanism 500 to drop powder.

It can be understood that the second plate 522 and the powder receiving assembly 510 can be provided with a sliding matching track to facilitate the sliding of the powder receiving assembly 510.

Through the above-mentioned structural coordination, the quantitative powder can be transported and blanked, and the quantitative and feeding are set separately.

Specifically, a feed pipe 250 for replenishing powder can be provided on the top of the silo 200, and the feed pipe 250 can lead out new powder. In order to accurately quantify, the powder generally needs to be stirred before entering the silo 200, so a stirring tank can be provided, and the feed pipe 250 can be installed between the stirring tank and the silo 200. The powder can be stirred evenly in the stirring tank by a stirring device, so that the density of the powder can be relatively uniform. The feed pipe 250 can introduce the evenly treated powder into the silo 200. The powder stored in the silo 200 will not change in density in a static state, thereby facilitating the subsequent quantitative filling process.

[0051] In some embodiments of the present invention, a partition net (not shown in the figure) is provided in the material chamber 210, and the partition net can further separate the powder evenly, and can also filter out some large impurities to avoid impurity blockage.

[0052] Reference Figures 2 to 5 In some embodiments of the present invention, the diameter of the discharge port 220 gradually decreases toward the quantitative plate 310, which can guide the powder to fall and prevent accumulation and jam.

[0053] It should be noted that the first through hole 111, the second through hole 511A and the blanking hole 522A can be configured to have a gradually decreasing aperture from top to bottom to reduce the occurrence of material accumulation and material jamming.
