In actual microstress assembly, the surface shape of the lens 02 is degraded due to assembly stress, adhesive shrinkage stress, structural stress generated by optical finish machining and the like, and finally the image quality of the lens is degraded, and at this time, the lens 02 with the degraded surface shape needs to be removed for microstress assembly again.

In the prior art, the first step of disassembly of the lens group is the disassembly of the pressing ring, which is usually connected into a tooth socket on the pressing ring through a pressing ring disassembly tool, and the pressing ring is disassembled by applying torque to the pressing ring; however, because the clamping ring is smeared with anti-loose glue, the clamping ring can be detached only by a large torque, and the problem that the connecting failure of the clamping ring detaching tool and the clamping ring tooth slot is caused by the overlarge torque easily occurs in the process of detaching the clamping ring by the existing clamping ring detaching tool, so that the lens is scratched is solved. The second step of lens removal is lens removal, which is commonly done as follows: (1) and (3) heat disassembly: heating the lens group to a certain temperature locally or wholly to soften the adhesive and reduce the strength, and loading a certain axial force through a degumming device to detach the lens; according to the thermodynamic characteristics of the adhesive, a reasonable thermal disassembly process is formulated; considering the heat resistance of the lens, particularly the film layer, the heating temperature is generally not too high; (2) chemical disassembly: soaking the adhesive layer by using a chemical solvent, destroying the adhesive structure to cause the adhesive structure to be aged and disabled, and loading a certain axial force through a degumming device to detach the lens; the method needs to consider the structural characteristics and the feasibility of the lens group, and particularly needs to avoid the pollution and the damage of the chemical solvent to the film layer; (3) mechanical disassembly: the adhesive structure is destroyed by a physical method, the adhesive area is reduced to reduce the adhesive strength, and then the lens is removed by loading larger axial force through the degumming device; the method is complex to operate when the adhesive structure is damaged, and the lens group is easy to damage.

In summary, the disassembly operation of the existing lens assembly is complex, and the lens is easy to damage in the disassembly process.
