Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to an automatic feeding device for coil processing. Background Art

[0002] With the development of modern industry, a large number of new electronic components have emerged and are being applied across various industries. For example, inductors, whose production and processing has always been labor-intensive and high-precision, have emerged. With the increasing demand for industrial automation and the desire to reduce production costs, a variety of automated, fast, and efficient specialized machines have emerged. Inductors, also known as inductors or coils, are devices that operate on the principle of electromagnetic induction. They are wound from insulated wire (such as enameled or yarn-covered wire), either coiled in turns around a paper tube or bakelite frame or directly around a magnetic core. Inductors primarily isolate and filter AC signals or form resonant circuits with capacitors, resistors, and other components.

[0003] The existing automatic coil feeding device includes a frame, a control mechanism and a magnetic mechanism, which has achieved the purpose of moving the coil from the storage position to the unloading position. The control mechanism (such as a robotic arm) is the core part of the entire feeding device. By receiving signals from sensors, operating interfaces or other control systems, it accurately controls the magnetic mechanism to perform lifting, moving and rotating movements. When the magnetic mechanism reaches the storage position of the coil, the magnetic mechanism receives the signal and controls the electromagnet to be energized. The electromagnet generates a magnetic field and adsorbs the coil placed at the storage position. After the control mechanism controls the magnetic mechanism to move from the storage position to the unloading position, the magnetic mechanism When the signal is received, the electromagnet is controlled to be de-energized, the magnetic field of the electromagnet disappears, and the coil loses its adsorption force, thereby releasing the coil from the magnetic mechanism to the unloading position. However, if the magnetic mechanism and the electromagnet work for a long time, the temperature of the electromagnet may increase, causing the magnetism of the electromagnet to decrease, and the adsorption force of the electromagnet to the coil to decrease. In addition, in the working environment, the electromagnet may be interfered with by other strong magnetic field sources, such as nearby motors, transformers or large electromagnetic equipment, thereby affecting the magnetic field distribution of the electromagnet and causing unstable adsorption. This deviation may cause the coil to fail to accurately reach the predetermined position, thereby affecting the subsequent processing process and assembly accuracy.

[0027] The driving mechanism includes a driving motor 12, a driving sprocket 13, a driven sprocket 14, a plurality of gears 16, a plurality of connecting rods 18 and a plurality of driving sprockets 17. The driving sprocket 13 and the driven sprocket 14 are both movably arranged on the mounting frame 7. The driving motor 12 for driving the driving sprocket 13 to rotate is fixedly connected to the mounting frame 7. A chain 15 is connected between the driving sprocket 13 and the driven sprocket 14. The outer walls of the plurality of driving sprockets 17 are connected to the chain 15. The bottom ends of the plurality of driving sprockets 17 are fixedly connected to the upper ends of the gears 16 through connecting rods 18. The spacing between two adjacent gears 16 is equal. The plurality of connecting rods 18 are movably penetrated and movably arranged on the bottom wall of the mounting frame 7. The two sides of 16 are respectively engaged with the first rack 19 and the second rack 20, and the ends of the first rack 19 and the second rack 20 away from each other are fixedly connected to the upper end of the movable plate 8, and the other ends of the first rack 19 and the second rack 20 away from each other are movable through the upper end of the movable plate 8.
