Description

Technical Field

[0001] This invention relates to a lens assembly disassembly device, specifically to a lens assembly disassembly device and disassembly method adapted to aerospace optical lenses. Background Technology

[0002] In the assembly process of aerospace optical lenses, applying adhesive to the outer circumference of the lens barrel is a common method to ensure the stability and optical accuracy of the lens structure. However, after the adhesive is cured, a high-strength bond is formed between the lens assembly and the lens barrel, making the disassembly of the lens assembly extremely difficult.

[0003] The existing disassembly process requires first cleaning the glue injection hole on the outer circle of the lens barrel, then injecting organic solvents such as gasoline into the glue injection hole. The solvent soaking causes the residual glue in the glue injection hole to expand and overflow, thereby weakening the bonding strength between the lens assembly and the lens barrel. Finally, the lens is inverted, and after a soft pad is placed on the supporting table, the lens is forced to detach from the lens barrel by hitting it with external force.

[0004] However, the above disassembly process has significant drawbacks: during the impact of external forces, the lens assembly is prone to scratches, dents and other damage due to uneven force, which affects the accuracy and performance of the optical lens. In addition, the overall operation process is cumbersome, the disassembly efficiency is low, and it is highly dependent on the experience of the operators, which further increases the risk and difficulty of disassembly. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems of existing disassembly processes, such as cumbersome overall operation procedures, low disassembly efficiency, high dependence on operator experience, and high disassembly risks and difficulties, and to provide a lens assembly disassembly device and disassembly method adapted to aerospace optical lenses.

[0024] Furthermore, the connector is a disc with external threads on its outer side wall, and the top of the connector is fixedly connected to the bottom end of the guide rod. The external threads are used to connect with the internal threads of the lens assembly to be disassembled.

[0025] Furthermore, the inner wall of the protective cover has a stepped structure, and an isolation protection ring is coaxially connected to the bottom of the inner wall. The isolation protection ring is made of polytetrafluoroethylene or silicone rubber.
