In addition, because the first display screen positioning component contains rotary driving piece, rotatory piece and lean on the position gyro wheel, rotary driving piece has the rotation axis that is the level and arranges, and one tip and the rotation axis fixed connection of rotatory piece lean on the position gyro wheel rotationally to install at the other tip of rotatory piece, can conveniently adjust lean on the position of position gyro wheel in the direction perpendicular to the direction of delivery of feeding assembly line for the expansion angle of the display screen of notebook computer of different specification sizes can all be adjusted to the angle of predetermineeing.

In addition, because the adjusting driving piece is further arranged between the leaning strip and the positioning moving frame in the second display screen positioning component, the horizontal distance between the leaning strip and the leaning roller can be conveniently adjusted, and the unfolding angles of the display screens of the notebook computers with different specifications and sizes can be adjusted to 90 degrees.

In addition, because the detection station assembly line is provided with a supporting component, the supporting component comprises an upper beam, a bottom beam, two upright posts, two lower fastening nuts, two bearing nuts and two upper fastening nuts, the two upright posts are respectively positioned at two end parts of the upper beam and the bottom beam, the upper end part and the lower end part of each upright post are provided with threads, and the lower end parts of the upright posts are arranged in the threaded holes of the bottom beam and are provided with the lower fastening nuts; the upper end of the upright post penetrates through the upper beam, the bearing nut is arranged below the upper beam, the upper fastening nut is arranged above the upper beam, and the height of the detection station assembly line can be conveniently adjusted so that the detection station assembly line is matched with the heights of the feeding assembly line and the discharging assembly line.

It should be appreciated by those skilled in the art that the foregoing embodiments are preferred embodiments of the present utility model, and are intended to be construed as illustrative only and not limiting the scope of the utility model.
