The bottom end of the telescopic rod 504 is movably connected to the inside of the cylinder 505.

[0028] The specific implementation method for material handling is as follows: The cylinder 505 pulls the movable pusher plate 502 down to the placement plate 501 through the telescopic rod 504, so that the top of the inclined surface of the movable pusher plate 502 is flush with the top surface of the placement plate 501.

[0029] The working principle of this utility model:

[0030] The working principle of the feeding mechanism: the cylinder 505 pushes the movable pusher plate 502 up and down through the telescopic rod 504, and realizes material picking and feeding in this process.

[0031] The working principle of the sweeping mechanism: The motor 608 controls the turntable 601 to rotate back and forth, so that the connecting rod 602 can move up and down, and through the connecting rod 603, the sector tooth plate 604 is rotated, which in turn causes the gear 605 meshing with it to rotate. As a result, the long rod 606 rotates, causing the brush plate 607, which is fixedly connected to the long rod 606, to rotate left and right, thus cleaning the screws in abnormal positions on the straight material channel 301.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
