Description

Technical Field

[0001] This utility model relates to the field of ferrite cores, specifically to a zirconium powder laying device for a magnetic core. Background Technology

[0002] In the field of electronic component manufacturing, surface insulation treatment of ferromagnetic cores (such as manganese-zinc ferrite cores) is a key process step to ensure their high-frequency performance and reliability. Traditionally, zirconium powder (zirconia powder) is evenly spread onto the surface of the ferromagnetic core manually or semi-automatically to form an insulating coating. However, existing technologies have the following significant drawbacks: manual spreading is uneven and inefficient; when using machines, the powder is spread intermittently, requiring a stop after one ferromagnetic core is laid and a replacement for the next. Therefore, the uneven distribution of zirconium powder at the beginning of the spreading process also leads to uneven application.

[0003] Therefore, in order to solve the above-mentioned problems, a zirconium powder laying device for magnetic cores is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing a zirconium powder spreading device for magnetic cores. This device can pre-spread zirconium powder before spreading it onto the ferromagnetic core, ensuring uniform powder distribution before the zirconium powder is applied to the ferromagnetic core, thus achieving a more uniform powder spreading effect.

[0005] To achieve the above objectives, this utility model provides a zirconium powder laying device for a magnetic core, comprising: a supporting table, a driving mechanism, a powder spreading mechanism, a load-bearing lifting device, and a powder receiving device. The driving mechanism is installed on the upper part of the supporting table, and the powder spreading mechanism is connected to the driving mechanism. The driving mechanism drives the powder spreading mechanism to move horizontally. A notch is provided at one end of the supporting table, and the load-bearing lifting device is placed below the notch. The ferromagnetic core is placed on the load-bearing lifting device, and the powder receiving device is fixedly connected to the supporting table and located below the powder spreading mechanism.

[0006] In this way, the powder-spreading mechanism first spreads powder before running above the ferromagnetic core to ensure uniform zirconium powder output. Then, the powder is spread and laid on the ferromagnetic core. The zirconium powder that was spread in advance falls onto the powder receiving device for collection to prevent waste.

[0007] Furthermore, the powder-spreading mechanism includes: a hopper, a powder-discharging mechanism, a discharge port, and a slit. The two ends of the hopper are connected to the driving mechanism. The discharge port is provided at the lower part of the hopper. The powder-discharging mechanism is rotatably connected to the discharge port. The slit is provided at the discharge port. The powder-discharging mechanism can close and open the slit by rotating.

[0008] Furthermore, the powder discharging mechanism includes: a rotating shaft, a protrusion, and a motor. The motor is fixedly connected to the lower part of the hopper, the rotating shaft is connected to the motor and located at the discharge port, and the protrusion is fixedly connected to the outer surface of the rotating shaft.

[0009] In this way, the protrusion is only located on a part of the rotating shaft. Therefore, when the rotating shaft rotates, the protrusion will rotate with it, thus achieving the sealing and opening of the slit. After opening, the zirconium powder can fall down.

[0010] Furthermore, the lifting device includes: a movable base, an electric lifting rod, and a platform. The electric lifting rod is installed on the upper part of the movable base, and the platform is installed on the upper part of the electric lifting rod. The ferromagnetic core is placed on the platform. A positioning plate is provided at the lower part of the supporting table. The positioning plate is located at the end of the powder receiving device, and the platform is in contact with the positioning plate.

[0011] Furthermore, the powder receiving device includes: a receiving part, a collecting trough, a door panel, a magnet, a hook, and a clamping plate. The receiving part is fixedly connected to the supporting table and located at the lower part of the powder spreading mechanism. One end of the collecting trough is rotatably connected to the lower part of the receiving part, and the other end of the collecting trough is rotatably connected to the door panel and the lower part of the door panel is connected to the magnet. The lower end of the door panel is fixedly connected to the magnet. The upper part of the collecting trough is fixedly connected to the clamping plate. One end of the hook is rotatably connected to the lower part of the receiving part, and the other end is engaged with the clamping plate.

[0012] Using the above method, the falling zirconium powder can be collected through the collection trough. Pull up the hook, disconnect it from the card plate, open the door, and then tilt the collection trough to collect the zirconium powder from the mobile phone.

[0013] Furthermore, it also includes a compaction device installed on top of the silo.

[0014] Furthermore, the filling device includes: a rotating plate, a push rod, a pressure plate, and a vibration motor. One end of the rotating plate is rotatably connected to the top of the hopper, the push rod is slidably connected to the rotating plate and its end is placed inside the hopper, the pressure plate is connected to the end of the push rod located inside the hopper, and the vibration motor is installed on the side of the hopper.

[0015] To ensure more uniform distribution of zirconium powder during its descent, the above method utilizes a vibrating motor to evenly distribute the powder, followed by compaction with a pressure plate to further enhance uniformity. The vibrating motor also operates during the powder feeding and spreading process to assist in the powder's distribution.

[0016] In summary, this utility model has the following advantages and beneficial technical effects:

[0017] 1. The present invention provides a zirconium powder spreading device for a magnetic core, which can pre-spread zirconium powder before spreading it onto the ferromagnetic core, so that the zirconium powder is evenly discharged before being spread onto the ferromagnetic core, thus achieving a more uniform powder spreading effect.

[0018] 2. This utility model can collect the pre-spread zirconium powder through a receiving device, thus avoiding the waste of resources;

[0019] 3. The lifting device of this utility model can adjust its height by rising and falling under the control of the controller. When the transported ferromagnetic cores are piled up too high, the height will be lowered to facilitate the spreading mechanism to lay zirconium powder. Attached Figure Description
