[0038] Furthermore, the controller 9 compares the relative position of the lens adsorbed by the absorbent 83 and the absorbent 83 captured by the bottom imaging device 7 with the pre-stored coordinates.

[0045] In a specific implementation process, the lens is first placed in a plurality of mounting openings 63 in the lens area on the object carrier 6, the controller 9 controls the first sliding device 3 to drive the second sliding device 4, and then drives the assembly structure 8, and controls the third sliding device 5 to move forward and backward, so that the absorber 83 of the assembly structure 8 is placed above the lens, the motor 81 controls the absorber 83 to absorb the lens, the first sliding device 3 drives the second sliding device 4 and then drives the absorber 83 to slide above the bottom imaging device 7, the bottom imaging device 7 confirms the center coordinates of the lens after taking a photo, and confirms whether the relative position of the absorber 83 and the lens is consistent with the pre-stored coordinates of the absorber 83 and the lens according to the pre-stored coordinates of the absorber 83 and the lens. If they are the same, if they are different, the first sliding device 3 drives the absorbent 83 to the adjustment area, and after adjustment, it slides to the top of the bottom imaging device 7 for reconfirmation until the adjustment is the same as the pre-stored value, and then the absorbent 83 is slid into the lens barrel area with the cooperation of the first sliding device 3 and the third sliding device 5, and then the upper imaging device 10 takes a picture of the lens barrel and transmits it to the controller 9. The controller 9 confirms that the lens and the lens barrel are at the same center coordinates based on the lens coordinates taken by the bottom imaging device 7 and the coordinates of the lens barrel taken by the upper imaging device 10, and then the absorbent 83 places the lens on the lens barrel, and the second sliding device 4 drives the mounting rod to assemble the lens and the lens barrel.
