[0089] In this embodiment, the technical solution and structure of the unloading unit 600 are similar to those of the picking unit 300, so the unloading unit 600 is not described in detail. The difference between the two is that the picking unit 300 is used to move the finished packaged product 800 onto the turntable unit 700, and the unloading unit 600 is used to move the finished packaged product 800 out of the turntable unit 700.

[0090] The present invention also provides a contact lens outer package sealing quality inspection system, including a turntable unit 700 for moving the finished package 800, a material taking unit 300 for carrying the finished package 800, a cup body visual inspection mechanism 400, a sealing visual inspection mechanism 500, and a plurality of unloading units 600 are arranged along the turnover path of the turntable unit 700. The contact lens outer package sealing quality inspection system adopts the material taking unit 300 to cooperate with the turntable unit 700 to realize the automatic loading of the finished package to be inspected, and the cup body visual inspection mechanism 400 and the sealing visual inspection mechanism 500 detect various defects of the finished package 800; and the multiple unloading units 600 are used to grade the unloading in the unloading area, replacing the existing manual inspection, improving the inspection efficiency, thereby improving the quality of the product, and at the same time sorting different visual inspection results, so as to facilitate further operation and processing of different inspection results.

[0091] The specific embodiments described in the present invention are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
