Description of the Invention: [Technical Field] The present invention relates to a method for processing a calendering sheet, and particularly relates to a filter processing and fixing method for improving the assembly yield of a product. [Prior Art] Dense optical wavelength division multiplexing (DWDM) filtering and optical film are the current ones. This kind of fluorescent film needs to reach more than one hundred layers of vacuum in the vacuum film in order to achieve a certain optical characteristic. The twilight film is repeated with high and low refractive index. The vacuum deposition of high and low refractive index materials and the auxiliary vapor deposition of the ion gun will produce a great force, resulting in four filters 100 when cutting the finished product. The angle cracks and falls off to form the missing 101 (see the first figure). This problem will cause the defective products in the back assembly to be disassembled. When the g is the group, the light will be attached to the optical lens (GRIN LENS) 200, attached. The work is fixed by special glue 4,. Because the collagen is in a liquid state, it will be covered in the entire mirror-like filter when it is rotated. After heating, the two can be glued together. However, in the point section, the miscellaneous division will fill in the four corners of the thief light sheet at the same time. When the heating temperature exceeds 80 degrees, the glue will change due to the physical change of heat expansion and contraction. The glue in the four corners will be filtered. The light sheet is lifted or squeezed a small amount, causing the filter to not be flat with the entire surface of the lens. Given together, and a gap is formed between the lens 2〇〇 3〇〇 1〇〇 and filter, resulting in fatigue flaw in the entire optical system is assembled. In view of this, it is indeed necessary to provide a new method of product processing and fixing to overcome the shortcomings of the prior art.

The filter processing and fixing method of the present invention performs a core taking step after the filter is cut, so that the filter having the corner angle becomes a filter having no corners, so that the filter can be closely attached to the optical lens. Effectively improving the yield on the product assembly β [Embodiment] The detailed description and technical contents of the filter processing and fixing method of the present invention will now be described with reference to the accompanying drawings: " Please refer to the second figure, the present invention A filter processing fixing method, which first comprises the step of cutting the filter U -|, and cutting the filter i into a cube shape as shown in the third figure, the cube being due to the reasons described in the aforementioned S-known technique The filter will produce a missing corner 10. After the filter d step is completed, the cut cubic filter is cored into a cylindrical shape by a core picking technique (as shown in Fig. 4). In this step, the core picking technology adopts the existing conventional core picking technology, and will not be described here. Referring to the fifth figure, the filter after the core is taken out is cylindrical, and the flat portion of the filter 1 after the core is taken toward the optical lens 2, and the glue 4 is applied to the filter through the dispensing operation. Between the sheet 1 and the photo-optical lens 2, after the glue is heated and cured, the filter 1 can be glued and fixed to the optical lens 2 1298396.
