Description

Technical Field

[0001] This utility model relates to the field of powder filling technology, and in particular to a powder quantitative dispensing device. Background Technology

[0002] The integrally molded inductor is made by embedding magnetic powder in the winding itself into the metal material and pressing it. The existing powder feeding mechanism is a device set on a servo press for discharging powder to add powder to the molding cavity. The powder is stored in a material box through a conduit, and finally the powder feeding device is pushed to the molding cavity by air pressure and motor drive to complete the pressing.

[0003] However, in the actual powder addition process, due to the influence of powder flowability, humidity and bulk density, the error range of powder dispensing by moving the powder through air pressure and motor drive is relatively large. When pressing inductors, if the powder deviation is large, it will lead to uneven inductor density and affect the inductor characteristics.

[0004] Therefore, there is an urgent need for a powder quantitative dispensing device to solve the above problems. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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 refer to the internal communication of two components or the interaction 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.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] This embodiment provides a powder quantitative dispensing device, which improves the accuracy / precision of the discharged powder weight. For example, in the application scenario of inductor manufacturing, it avoids the problem of uneven inductor density during batch manufacturing, which affects the inductor characteristics and consistency.

[0032] like Figures 1-2 As shown, this utility model provides a powder quantitative dispensing device, including a storage component 1, a dispensing mechanism, a driving mechanism 4, and a positioning column 5. The storage component 1 stores powder. The dispensing mechanism includes a dispensing pipe 3 and a dispensing rod 2, with the dispensing rod 2 passing through the dispensing pipe 3. The storage component 1 is connected to the dispensing pipe 3 to allow powder to enter the dispensing pipe 3. The driving mechanism 4 drives the dispensing rod 2 to move, discharging the powder from the dispensing pipe 3. One end of the positioning column 5 is connected to the output end of the driving mechanism 4, and the other end of the positioning column 5 is connected to the dispensing rod 2. With the above configuration, when driving the discharge rod 2, the positioning column 5, as a rigid intermediate connector, can eliminate gaps and accurately transmit the movement of the output end of the drive mechanism 4 to the discharge rod 2. Furthermore, the positioning column 5 ensures that the axes of the drive mechanism 4 and the discharge rod 2 are aligned with the axis of the discharge pipe 3, preventing unilateral wear, jamming, or uneven discharge caused by eccentricity of the discharge rod 2. This improves the accuracy of the weight of powder discharged each time, thus improving the precision of powder packaging and avoiding the problem of uneven inductance density affecting inductance characteristics and consistency. In this embodiment, the connection between the storage component 1 and the discharge pipe 3 is located on the outer periphery of the discharge pipe 3, not on the end face, thereby enabling the introduced powder to be discharged from the discharge pipe 3.

[0033] In some embodiments, the powder dispensing device further includes a weighing mechanism (not shown in the figure). The weighing mechanism weighs the powder discharged from the discharge pipe 3. An alarm is installed in the weighing mechanism, which is configured to sound an alarm if the weight of the powder is outside a preset weight range. It is understood that if the weight of the powder is outside the preset weight range, it indicates that the powder discharged from the discharge pipe 3 is unqualified, and the alarm sounds to remind manual inspection and adjustment. If the weight of the powder is within the preset weight range, it indicates that the powder discharged from the discharge pipe 3 is qualified. At this time, the weighed powder can be dispensed and transported, completing one powder dispensing operation.

[0034] It should be noted that whether the powder weight is qualified or unqualified refers to whether the powder weight is within the preset weight range. If it is within the preset weight range, it means that the weight of the discharged powder is qualified and the difference from the ideal weight is small. There will be no problem of uneven inductance density affecting the inductance characteristics. If it is outside the preset weight range, it means that the weight of the discharged powder is qualified but the difference from the ideal weight is large. During the manufacturing of the inductor, uneven inductance density will occur, affecting the inductance characteristics. The preset weight range can be determined according to the actual use requirements. This embodiment does not make a specific limitation.

[0035] To facilitate the installation of the above-mentioned device, in this embodiment, as follows: Figures 1-2 As shown, the powder dispensing device also includes a housing 6, on which the dispensing mechanism and the drive mechanism 4 are both mounted. It is understood that the housing 6 provides a robust and stable mounting base for the dispensing mechanism and the drive mechanism 4, protecting the precision components within them from external environmental damage, preventing accidental contact with moving parts by operators, and improving the stability and safety of the powder dispensing device.

[0036] In this embodiment, the weighing mechanism is located outside the outer shell 6, and the end of the discharge pipe 3 away from the drive mechanism 4 protrudes from the outer shell 6, which facilitates docking with the weighing mechanism and makes it easy to weigh the discharged powder.

[0037] Furthermore, the powder dispensing device also includes a control board, which is electrically connected to the drive mechanism 4 for automatically controlling the opening and closing of the drive mechanism 4. The control board is also communicatively connected to the weighing mechanism. Specifically, the control board is equipped with a control module that can shut down the drive mechanism 4. The control unit is communicatively connected to the controller within the weighing mechanism. It is understood that if the powder weight is outside the preset weight range, it indicates that the powder discharged from the discharge pipe 3 is unqualified. In this case, the drive mechanism 4 is in the closed state, facilitating manual inspection and adjustment of the powder dispensing device to ensure that the weight of subsequently discharged powder is qualified.

[0038] In this embodiment, the alarm can be one or more of a buzzer and a warning light to easily alert workers. The controller in the weighing mechanism is communicatively connected to the weighing sensor and the alarm. After the powder is discharged, the drive mechanism 4 is in the off state. The controller processes the weight data obtained by the weighing sensor and determines whether it is within the preset weight range. If not, it transmits a signal to the alarm to issue an alarm signal, facilitating manual inspection and adjustment of the powder quantitative dispensing device. The control board, control module, weighing sensor, alarm, and controller are all existing technologies. Their specific types and connections can be determined according to actual usage requirements, and this embodiment does not impose specific limitations.

[0039] Regarding the packaging and transportation of powder, in this embodiment, the powder quantitative packaging device can be equipped with existing transportation mechanisms such as conveyor belts to package and transport the weighed powder. The mechanism for packaging and transporting powder can be determined according to actual usage requirements and is not the focus of improvement in this embodiment. This embodiment does not make specific limitations on this aspect.

[0040] Furthermore, such as Figure 2 As shown, a storage channel 11 is provided inside the storage component 1, and the storage channel 11 is connected to the discharge pipe 3. The inlet 111 of the storage channel 11 is located at the end of the storage channel 11 away from the discharge pipe 3. By providing a storage channel 11 inside the storage component 1, when storing powder in the storage component 1, the powder can directly enter the discharge pipe 3. When discharging the powder, the drive mechanism 4 can be directly activated, making operation labor-saving.

[0041] Exemplarily, the drive mechanism 4 drives the discharge rod 2 to rotate. A threaded section 21 is provided at the end of the discharge rod 2 away from the drive mechanism 4, and the storage channel 11 is directly opposite the threaded section 21. Specifically, the drive mechanism 4 drives the discharge rod 2 to rotate around its own axis, while the position of the discharge rod 2 relative to the discharge pipe 3 remains unchanged along its length. It is understood that the storage channel 11 is positioned directly opposite the threaded section 21 to facilitate feeding material to the location of the threaded section 21. As the drive mechanism 4 drives the discharge rod 2 to rotate, powder is gradually discharged during the rotation of the threaded section 21. In this embodiment, the pitch of the threaded section 21 is small, facilitating precise control of the powder flow rate and further minimizing errors.

[0042] In this embodiment, the storage component 1 has a thread on its outer side. The end of the storage component 1 away from the discharge pipe 3 has a chamfered end where the inlet 111 is located, which facilitates docking with other powder storage devices to achieve continuous feeding.

[0043] Furthermore, the discharge port 31 of the discharge pipe 3 is located on the end face of the discharge pipe 3 away from the drive mechanism 4, and the end face of the discharge rod 2 away from the drive mechanism 4 is basically flush with the end face of the discharge pipe 3 away from the drive mechanism 4, or slightly protrudes from the end face of the discharge pipe 3 away from the drive mechanism 4, thereby facilitating material discharge.

[0044] Furthermore, the length of the threaded section 21 occupies approximately 60% of the length of the discharge rod 2. Of course, in other embodiments, the proportion of the threaded section 21 to the length of the discharge rod 2 can be determined according to actual usage requirements.

[0045] In this embodiment, the amount of powder discharged from the discharge pipe 3 mainly depends on the rotational speed and running time of the discharge rod 2. The rotational speed can be adjusted to a preset speed, and the running time of the drive mechanism 4 can be set to a fixed value using a control board. For example, it can be automatically turned off after each preset time to ensure the output of a fixed amount of powder. When needed, it can be turned on again. The preset speed and preset time can be determined according to actual usage requirements, and this embodiment does not impose specific limitations.

[0046] Furthermore, the storage component 1 is located above the discharge pipe 3. It is understood that with the storage component 1 located above the discharge pipe 3, the powder in the storage channel 11 can move towards the discharge pipe 3 by its own gravity, eliminating the need for an additional pushing structure, saving costs, reducing the space occupied by the pushing mechanism, and preventing the powder in the storage channel 11 from being over-compressed.

[0047] In this embodiment, the storage component 1 is a storage tube, which can realize quantitative storage and transport powder of precise volume or weight to the discharge tube 3, and has the functions of easy filling and monitoring. In this embodiment, the storage component 1 is cylindrical, and the storage channel 11 is a circular channel, which facilitates the movement of powder and subsequent cleaning. Of course, in other embodiments, the storage component 1 and the storage channel 11 can also be in other shapes, as long as they meet the actual use requirements, and this embodiment does not impose specific limitations.

[0048] Furthermore, the drive mechanism 4 includes a drive component 41 and a reducer 42 connected by a transmission connection, and the end of the positioning post 5 away from the discharge rod 2 is connected to the output end of the reducer 42. It can be understood that the initial speed of the drive component 41 is relatively high. By setting the drive component 41 and the reducer 42 connected by a transmission connection, it is convenient to reduce and adjust the drive speed to meet the usage requirements of the discharge rod 2.

[0049] In this embodiment, the drive unit 41 can be a DC servo motor. The DC servo motor provides power, provides a precise rotation angle for the feed rod 2, can be flexibly programmed with different speeds to adapt to different powder characteristics and process requirements, and the servo system has a fast dynamic response speed and can accurately execute complex motion control commands.

[0050] In this embodiment, the reducer 42 can be an existing reducer. The reducer reduces the high speed output by the DC servo motor to a controllable and lower operating speed required by the discharge rod 2. Reducing the speed helps to improve the control accuracy of the position and speed of the discharge rod 2, while amplifying the output torque to provide sufficient force to overcome the resistance in the powder discharge process.

[0051] Furthermore, the control board and the drive unit 41 are connected by a connecting cable 7. Part of the connecting cable 7 is located inside the housing 6, and the housing 6 has a receiving hole through which the connecting cable 7 can pass. A flexible component is provided on the inner wall of the receiving hole. Using a flexible component reduces wear on the connecting cable 7 and prevents rapid wear at the connection point between the connecting cable 7 and the drive unit 41 due to bending or other factors, thus improving service life. The flexible component is a conventional flexible component.

[0052] Furthermore, a coupling 8 is provided between the reducer 42 and the positioning column 5. One end of the coupling 8 is connected to the reducer 42, and the other end is connected to the positioning column 5. It is understood that by providing the coupling 8, the indirect transmission connection between the reducer 42 and the positioning column 5 is facilitated, enabling the transmission of motion and torque, and providing a buffering and shock-absorbing effect. In this embodiment, the coupling 8 is a bellows coupling 8, which can absorb the radial and axial deviations present in the reducer 42, preventing wear on the discharge rod 2 and damage to the powder metering and dispensing device.

[0053] In this embodiment, both the discharge pipe 3 and the discharge rod 2 are made of ceramic. It is understood that ceramic components have high wear resistance, non-magnetic properties, and insulation, which can ensure the stability of the powder weight discharged each time.

[0054] In this embodiment, the process of using the powder quantitative dispensing device is as follows:

[0055] First, the powder is fed into the storage container 1 through the feed inlet 111.

[0056] Then, turn on the drive mechanism 4 to drive the discharge part to move and discharge the powder.

[0057] Then, the drive mechanism 4 is turned off, and the weighing mechanism weighs the discharged powder.

[0058] If the powder weight is outside the preset weight range, an alarm will be issued, and the powder quantitative dispensing device will be checked and adjusted. After the check and adjustment, the powder will be re-injected. If the powder weight is within the preset weight range, the weighed powder can be dispensed and transported.

[0059] Then proceed to the next loop.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
