[0033] Please refer to Figures 1 to 5 , an automatic lens optical center adjustment device according to an embodiment of the present application, includes an operation table 10 for adjusting the lens, a sensor moving mechanism 20 for adjusting the distance between the sensor and the lens. The operation table 10 and the sensor are arranged opposite to each other. It further includes a lens adjustment mechanism 30 and an intermediate transfer mechanism 40 for picking and placing the lens at the operation table 10. The operation table 10 fixes the lens 50, and a fixing jig 11 for fixing the lens is correspondingly arranged at the operation table 10. A lens movement adjustment mechanism 51 is arranged at the lens 50. The lens movement adjustment mechanism 51 includes a first adjustment component 511 and a second adjustment component 512 for respectively adjusting the X-axis coordinate and Y-axis coordinate of the lens 52. The lens adjustment mechanism 30 includes an X-axis adjustment component 31 and a Y-axis adjustment component 32 for respectively adjusting the first adjustment component 511 and the second adjustment component 512; in this embodiment, as Figure 5 shown, the first adjustment component 511 includes a first adjustment rotating part 5111.

[0043] The following reference Figures 2 - 5 The process of adjusting the lens optical center of the lens optical center automatic adjustment device according to the embodiment of the present application is described as follows:

[0044] The intermediate transfer mechanism 40 first transfers the lens to the operation table 10 for preliminary center alignment. At this time, there is a slight positional deviation between the optical center of the lens and the optical path center. The fixed fixture 11 at the operation table 10 fixes the lens at the operation table 10; then, the lens adjustment mechanism 30 adjusts the lens displacement mechanism 51 at the lens. The X-axis adjustment assembly 31 at the lens adjustment mechanism 30 adjusts the first adjustment assembly 511 of the lens displacement mechanism 51. The first rotary electric screwdriver 311 of the X-axis adjustment assembly 31 is used to screw the first adjustment rotating part 5111 of the first adjustment assembly 511 to adjust the X-axis coordinate of the lens; the Y-axis adjustment assembly 32 at the lens adjustment mechanism 30 adjusts the second adjustment assembly 512 of the lens displacement mechanism 51. The second rotary electric screwdriver 321 of the Y-axis adjustment assembly 32 is used to screw the second adjustment rotating part 5121 of the second adjustment assembly 512 to adjust the Y-axis coordinate of the lens; after the automatic adjustment is completed, the optical center of the lens is consistent with the optical path center at this time; subsequently, as Figure 3 shown, the intermediate transfer mechanism 40 then drives the dispensing mechanism 41 at the transfer head 42 to the operation table 10. The dispensing mechanism 41 dispenses glue on the lens and performs UV curing after dispensing; finally, as attachedFigure 5 As shown, the sensor moving mechanism 20 drives the sensor at its location towards the lens at the operation table 10, achieving the docking of the fixed positions between the lens and the sensor.
