when the lifting assembly 3 is located at the feeding station, firstly, the inserting mechanism 15 in the first conveying assembly 1 acts to insert the push rod 152 into the inserting groove 101 of the tray 100 below the push rod; then, the first driving mechanism 14 acts to drive the mounting plate 13 to move and synchronously drive the tray 100 to move, so that the tray 100 is moved from the first conveying assembly 1 to the lifting assembly 3; then, the positioning assembly 39 in the lifting assembly 3 operates to insert the positioning shaft 393 into the positioning hole 102 of the tray 100, so as to position the tray 100; then, the second driving mechanism 34 of the lifting assembly 3 operates to drive the lifting assembly 3 to descend to the blanking station, and then the positioning assembly 39 in the lifting assembly 3 operates to drive the positioning shaft 393 to disengage from the positioning hole 102 of the tray 100; thereafter, the output mechanism 36 operates to output the tray 100 in the lifting unit 3 to the second conveyance unit 2.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
