[0002] After the lens is formed by using a mold, the parts to be assembled need to be assembled into the inner diameter of the lens barrel to form a complete lens.
[0003] For lenses with a small quantity, high precision requirements, and a small gap between the inner diameter of the lens barrel and the outer diameter of the parts to be assembled, the traditional assembly method is manual assembly at room temperature. The assembly is relatively difficult, and due to the very small gap, manual assembly at room temperature will cause the parts to be assembled to be prone to tilt, resulting in low assembly efficiency, poor performance after assembly, and easy scratching between the outer diameter of the parts to be assembled and the inner diameter of the lens barrel, leading to problems such as dirty inside the lens and high defect rate.
[0004] Therefore, how to efficiently and accurately assemble a lens with a small gap has become a technical problem to be solved. Summary of the Utility Model
