Description
Technical Field

[0002] Ferrite cores, as core components of electronic devices, typically undergo multiple steps in their molding process, including raw material pressing, sintering and shaping, and surface treatment. In traditional production processes, the molded cores often require secondary processing such as drilling, grinding, or slotting on independent equipment before they are fully formed to meet specific electrical performance or assembly requirements. Existing technologies for fine-tuning operations like grinding and drilling generally rely on manual tool replacement or parameter adjustment. This requires frequent interruptions to switch tools, increasing labor costs and easily leading to reduced machining accuracy due to operational errors. Furthermore, the tool replacement process is unstable, which can easily lead to dust contamination and increased tool wear, further compromising the surface quality of the core and the lifespan of the equipment.

The internal ferrite core that needs to be drilled is supported by arranging the support blocks and the support rings.
[0013] A processing method for a ferrite core forming device comprises the following steps: S1 Ferrite core workpiece positioning and tool preloading: Drill heads of different specifications are screwed into the internal thread barrels of the corresponding iron shafts through the connecting columns. Then the fourth motor is started to drive the second conical disk to rotate, which drives the four first conical disks engaged with it to rotate, thereby driving the four threaded columns to rotate synchronously, so that the four positioning frames clamp the ferrite core workpiece radially along the four moving grooves on the surface of the support ring; S2 Tool Selection and Circumferential Positioning: After the ferrite core workpiece is fixed, the third motor is started to drive the gear, causing the meshing gear ring to rotate, driving the swivel ring to rotate circumferentially. At this time, the electromagnet is energized to attract the iron shaft into the mounting ring. When the infrared transmitter of the target iron shaft forms an optical path with the infrared receiver of the mounting plate, the first electric telescopic rod pushes the chuck into the corresponding hole of the gear ring to lock the swivel ring. S3 power shaft docking and constraint release: After the swivel is locked, the first motor drives the threaded rod to rotate, driving the movable bar to move horizontally, so that the hexagonal prism is axially inserted into the hexagonal hole of the target iron shaft. At this time, the external PLC controller controls the lower electromagnet to cut off the power and release the magnetic constraint on the lower iron shaft; S4 coordinated drilling and dust treatment: After the hexagonal prism is axially inserted into the hexagonal hole of the target iron shaft, the second electric telescopic rod pushes the drilling head downward to contact the ferrite core workpiece. The second motor is simultaneously started to drive the iron shaft to rotate through the hexagonal prism to perform drilling processing. During the drilling process, the vacuum pump generates negative pressure airflow through the U-shaped vacuum box, and the processing dust is sucked into the storage box through the gap of the support ring and intercepted and deposited by the barrier net; S5 unloading: After drilling is completed, the second electric telescopic rod lifts the drilling head to the initial height, and then controls the four threaded columns to rotate so that the four positioning frames are away from the ferrite core workpiece, and then unloading is carried out.
[0014] Compared with the prior art, the beneficial effects of the present invention are: the ferrite core forming processing device and method have the following advantages: 1. The synergy between the swivel, electromagnet, and infrared positioning system enables tool preloading and intelligent switching. The PLC controller precisely controls the swivel's rotation angle, and combined with the optical signal matching between the infrared transmitter and receiver, ensures that the target tool is quickly positioned at the processing position, significantly improving processing efficiency and reducing manual intervention.
[0015] 2. The four-axis synchronous clamping mechanism uses a bevel gear set to drive the threaded column to rotate synchronously, so that the positioning frame applies force evenly in the radial direction. Combined with the support ring, the multi-point support of the workpiece effectively eliminates the risk of machining offset. The adaptive clamping design is compatible with ferrite cores of different specifications, ensuring machining stability and repeatability.
[0016] 3. During the drilling process, the U-shaped exhaust box and negative pressure suction device create a directional airflow, capturing dust particles in the processing area in real time. The coordinated design of the barrier net and storage box allows dust to be trapped and centrally processed, preventing environmental pollution and reducing the impact of tool wear on processing quality.
[0017] 4. A hexagonal prism-hexagonal hole power docking structure uses electromagnets to control the iron shaft constraint state, ensuring the reliability and safety of power transmission. Precise displacement control of the moving component enables rapid coupling between the tool axis and the power axis, meeting the flexible switching requirements of complex machining scenarios.

10. A method for forming a ferrite core, characterized in that: The following steps are involved: S1 ferrite core workpiece positioning and tool preloading: Drill heads (63) of different specifications are screwed into the internal thread barrels (61) of the corresponding iron shafts (24) through the connecting columns (62), and then the fourth motor (82) is started to drive the second conical disk (83) to rotate and drive the four first conical disks (75) engaged therewith to rotate, thereby driving the four threaded columns (74) to rotate synchronously, so that the four positioning frames (73) radially clamp the ferrite core workpiece on the surface of the support ring (11) along the four movable grooves (72); S2 Tool selection and circumferential positioning: After the ferrite core workpiece is fixed, the third motor (51) is started to drive the gear (52) to rotate, so that the gear ring (53) meshing with it rotates, driving the rotating ring (21) to rotate circumferentially. At this time, the electromagnet (27) is energized to attract the iron shaft (24) in the mounting ring (22); when the infrared transmitter (25) of the target iron shaft (24) and the infrared receiver (26) of the mounting plate (1) form an optical path conduction, the first electric telescopic rod (54) pushes the clamping head (55) to clamp into the corresponding clamping hole of the gear ring (53) to lock the rotating ring (21); S3 power shaft docking and constraint release: after the rotating ring (21) is locked, the first motor (33) drives the threaded rod (32) to rotate, driving the moving bar (31) to move laterally, so that the hexagonal prism (43) is axially inserted into the hexagonal hole of the target iron shaft (24).
