[0067] In this embodiment, the first carrier plate and the second carrier plate may be arranged sequentially along the guide rail, or may be arranged integrally.

[0068] In this embodiment, the frame 100 may also be provided with universal wheels 120 so that the entire system can be moved.

[0070] In this embodiment, Figure 1-Figure 3 A lens assembly method for a lens assembly system shown may include the following steps:

[0071] The lens is placed as a first target object on the first carrier plate 500, and the lens barrel is placed as a second target object on the second carrier plate 600;

[0073] The first driving unit 300 drives the guide base 210 to move along the first direction to the second position, and the second driving unit drives the first carrier 500 to move along the second direction to the fourth position;

[0074] The second driving unit drives the second carrier 600 to move along the second direction to the third position, and the first driving unit 300 drives the guide base 210 to move from the second position to the first position along the first direction, so as to transfer the lens adsorbed by the target object pick-and-place mechanism 200 to the lens barrel on the second carrier; and

[0075] At least when the target object picking and placing mechanism 220 carries the lens and contacts the lens barrel, the pressure-applying unit 400 applies pressure to the target object picking and placing mechanism 220 along a first direction. When the guide base 210 is located at the first position and the first carrier plate 500 or the second carrier plate 600 is located at the third position, the target object picking and placing mechanism 220 can contact the first target in the first carrier plate and adsorb the first target, or the target object picking and placing mechanism 220 can carry the first target and contact the second target in the second carrier plate, and transfer the first target to the second target.

[0076] It should be noted that when the object picking and placing mechanism 220 contacts the lens in the first carrier or the lens and the lens barrel, pressure can be generated in the first direction between the object picking and placing mechanism 220 and the first carrier or the second carrier.

[0077] In this embodiment, the method includes: after the target object picking and placing mechanism 220 fixes and adsorbs the lens, applying a first pressure to the target object picking and placing mechanism 220 along a first direction by the pressure-applying unit, and maintaining the first pressure until the target object picking and placing mechanism 220 carries the lens in contact with the lens barrel; or, when the target object picking and placing mechanism 220 fixes and adsorbs the lens and moves to a second position, applying a second pressure to the target object picking and placing mechanism 220 along the first direction by the pressure-applying unit, and maintaining the second pressure until the target object picking and placing mechanism 220 carries the lens in contact with the lens barrel.

[0078] In this embodiment, when the target object picking and placing mechanism 220 contacts the lens, or when the target object picking and placing mechanism 220 carries the lens and contacts the lens barrel, a relative displacement can be generated in a direction between the target object picking and placing mechanism 220 and the guide base, and when the first pressure is applied to the target object picking and placing mechanism 220, the first displacement length generated between the target object picking and placing mechanism 220 and the guide base is less than the second displacement length generated between the target object picking and placing mechanism 220 and the guide base when the second pressure is applied to the target object picking and placing mechanism 220.

[0079] In this embodiment, when the target object picking and placing mechanism 220 approaches the lens or contacts the lens, or when the target object picking and placing mechanism 220 carries the lens and approaches the lens barrel or contacts the lens barrel, the pressure-applying unit can drive the target object picking and placing mechanism 220 and the guide base 210 to generate relative movement in a first direction, so as to drive the target object picking and placing mechanism 220 to contact the lens and generate a predetermined pressure between the target object picking and placing mechanism 220 and the lens, or drive the target object picking and placing mechanism 220 to carry the lens and contact the lens barrel, and generate a predetermined pressure between the lens and the lens barrel, thereby achieving stable absorption of the lens by the target object picking and placing mechanism 220 and stable assembly between the lens and the lens barrel. It should be noted that the pressure provided by the pressure-applying unit is sufficient to assist in achieving stable absorption of the lens by the target object picking and placing mechanism 220 and stable assembly between the lens and the lens barrel, but will not cause pressure damage to the lens. The magnitude of the pressure is obtained by calculation and is not disclosed in detail herein.
