[0031] The utility model discloses a use time: through the drive motor 6 drive fixed link 7 and carry out the rotating operation, and then make the cam 8 synchronous rotation with the fixed link 7 middle part firm connection. Rotating cam 8 can exert pressure to the two stabilizing frames 3 fixed on the both sides of base 1, and stabilizing frame 3 is limited by the both sides inner wall of loading frame 4. Under this condition, loading frame 4 can move up and down, and produce vibration. The sheet electronic component placed in loading frame 4 is under the action of vibration, and can be shaken into the track groove 5.

[0032] Because the size of track groove 5 is accurately designed, can only accommodate single specification sheet electronic component, therefore the component will slide down along the track groove 5 of arc shape setting, finally falls into the corresponding recess 2 below. Realize the effect of stable loading, effectively avoid the improper loading of sheet electronic component and influence the normal operation of feeding device, and then reach the effect of improving the use effect of multi-track feeding device.

[0033] Example two
