[0031] The working principle of a feeding device for processing a circuit board drill bit proposed by an embodiment of the present invention is as follows:

[0032] Start the first motor 12, the drill bit processing equipment 4 starts, put the raw material into it. After processing, the drill bit falls into the chute 501, and the drill bit slides into the temperature increasing body 7 through the chute 501. The drill bit can complete the first temperature increasing effect after the drill bit is formed in the temperature increasing body 7, achieving the first step process for the drill bit not to be easily deformed and bent. Then start the third motor 705, the lifting mechanism inside the temperature increasing body 7 starts, and the heating plate 703 at the top of the temperature increasing body 7 is lifted by the second toothed plate 708 and the connecting plate 709 inside the temperature increasing body 7.

The standard cylinder 10 is started to contract the clamping jaws 908, so that the clamping jaws 908 clamp the drill bit, and clamp the drill bit in the temperature increasing body 7. Then the second rodless cylinder 11 moves to one side of the feeding box body 15, and the clamping jaws 908 rotate to the side close to the feeding box body 15. The standard cylinder 10 is started, and the clamping jaws 908 expand. When the clamping jaws 908 clamp the drill bit in the temperature increasing body 7, the ceramic heater 901 will continuously provide heat to the clamping jaws 908 through the heat conduction hose 902, which can achieve the effect of further heating the drill bit during the clamping process of the clamping mechanism 9. Finally, the drill bit falls into the feeding box body 15, thus completing the feeding process.
