[0053] In the embodiment, the component feeding device further comprises a lifting mechanism 5 used for lifting the feeding plate 21. The lifting mechanism 5 can also adopt other lifting devices in the art to drive the feeding plate 21 to lift. In order to improve the stability of the feeding plate 21 in lifting, the lifting mechanism 5 is arranged outside the placing box 2, and the lifting mechanism 5 comprises:

[0054] A motor 51 mounted on the mounting seat 1;

[0055] a screw rod 52 connected with the output end of the motor 51 and rotatable;

[0056] a screw rod sleeve 53 sleeved on the screw rod 52 and moving up and down with the rotation of the screw rod 52;

[0057] and a connecting rod 54 connected with the screw rod sleeve 53 at one end and passing through the side wall of the placing box 2 and connected with the feeding plate 21 at the other end. The motor 51 is installed on the back of the mounting seat 1 and provided with a mounting plate 55 supporting the motor 51, which is connected with the back of the mounting seat 1. The lifting mechanism 5 is arranged outside the placing box 2, so that the lifting mechanism 5 is not limited by the space of the placing box 2.

[0058] In this embodiment, the side wall of the placing box 2 close to the lifting mechanism 5 is provided with a first slot 23 through which the connecting rod 54 passes and moves up and down.

[0059] In this embodiment, the pushing mechanism 4 comprises:

[0060] a cylinder 41;

[0061] a telescopic rod 42 connected with the cylinder 41 and driven by the cylinder 41 to extend and retract;

[0062] and a pushing plate 43 connected with the telescopic rod 42 and used to push the component placing plate 22.

[0063] In this embodiment, the feeding plate 21 raises the topmost component placing plate 22 to the height outside the placing box 2. The height of the bottom surface of the pushing plate 43 is higher than the height of the placing box 2; the height of the bottom surface of the pushing plate 43 is higher than the height of the bottom surface of the topmost component placing plate 22; the height of the bottom surface of the pushing plate 43 is lower than the height of the top surface of the topmost component placing plate 22; the bottom surface of the topmost component placing plate 22 is higher than the height of the placing box 2; the height of the collecting box 3 is not higher than the height of the placing box 2.

Since the feeding plate 21 is connected by the connecting rod 54, the screw rod sleeve 53 drives the feeding plate 21 to move upward, and the feeding plate 21 moves along the sliding groove 26 to prevent the position from deviating during the lifting process. When the bottom surface of the topmost component placing plate 22 is lifted to be higher than the placing box 2, the motor 51 is controlled to stop working. Under the action of the external grabbing mechanism, the component is extracted. At this time, the cylinder 41 is controlled to work, driving the telescopic rod 42 to extend, so that the pushing plate 43 moves to the direction close to the component placing plate 22, pushing the component placing plate 22 to move into the collecting box 3. Since the height of the bottom surface of the pushing plate 43 is higher than the height of the bottom surface of the uppermost component placing plate 22, the pushing plate 43 does not affect the next layer of component placing plate 22 during the pushing process. The cylinder 41 is controlled to work, driving the telescopic rod 42 to contract, so that the pushing plate 43 returns to the original position. The motor 51 is controlled to continue to work, driving the screw rod 52 to rotate, so that the screw rod sleeve 53 moves upward with the rotation of the screw rod 52, driving the feeding plate 21 to move upward, so that the bottom surface of the next layer of component placing plate 22 is lifted to be higher than the placing box 2. Under the action of the external grabbing mechanism, the component is extracted. The above process is repeated to realize the feeding of components.
