The invention relates to the field of optical component processing, and in particular to an apparatus and method for disassembling an optical component.

With the rapid development of the optoelectronic industry, optical lenses are designed in various shapes to meet the needs of different products. Optical lens processing technology has also been rapidly developed, and people can obtain the required optical lenses through different processing methods (see "Precision Machining of Optical Mirrors", Manufacturing Technology and Machine Tools, No. 6 (1998).

In many applications, it is often necessary to process the optical lens into a circular shape, such as a lens for a camera, a lens for a lens, a lens for a magnifying glass, and a telescope. The current spheronization technique is to round the initially formed square optical lens so that the optical lens has a rounded edge to meet the optical application.

In the spheronization process of the optical lens, in order to improve the spheronization efficiency and the need for mass production, a plurality of optical lenses to be spheronized are usually adhered together by a bonding adhesive such as an ultraviolet curing resin to perform spheronization. At present, we degumming and cleaning the glass after the rounding with hot water, but often it is not effective to remove the residual glue, resulting in low production yield.

In view of the above, it is necessary to provide an apparatus and method capable of effectively removing the residue of the surface of the optical element.

The heat insulating unit 8 is disposed at the opening 122, and the heat insulating unit 8 in the opening 122 can be rotated 360 degrees. The optical component is fixed to the heat insulating unit 8 in the opening 122 through the overload carrier 9, and is fixed to the second cylinder 12. The heat insulating unit 8 prevents the external heat from being radiated into the second cylinder 12 during the freezing process to raise the temperature inside the second cylinder 12.

Of course, the heat insulating unit 8 can also be provided at a position other than the opening 122.

As shown in FIG. 3, the heat insulating unit 8 is a vacuum structure surrounded by a stainless steel 15 and a first cork 141. The stainless steel 15 and the first cork 141 are both hollow structures, and the first cork 141 is located in the hollow structure of the stainless steel 15.
