[0038] Working process and principle:

[0039] I. Preparation for assembly

[0040] First, the metal tube shell is put into the tube shell positioning groove 4 of the tube shell positioning mold 3 one by one. Then, the lens guide mold 2 is aligned with the positioning column 7 on the lens bearing mold 1 through the guide hole 8 on it and is stacked. Finally, the tube shell positioning mold 3 loaded with the metal tube shell is aligned with the positioning column 7 through the positioning hole 9 on it, is stacked at the bottom layer, and is supported and fixed through the bearing base 10, so that the assembly of the whole mold is completed.

[0041] II. Feeding cloth

[0042] A large number of lens blanks are poured into the storage area 102 of the lens bearing mold 1, and through shaking and vibrating the whole mold, the lens blanks enter the feeding area 101 in an orderly manner as a whole from the storage area 102, and fall into the arrayed lens release holes 6 in the feeding area 101 in the vibration, ensuring that each lens release hole 6 contains a lens blank. The guardrails prevent the lens blanks from flying out in this process.

[0043] III. Release guide

[0044] When the lens release holes 6 are filled, the excess lens blanks are removed. At this time, the lens blanks in the lens release holes 6 are released and vertically fall under the action of gravity. The lens blanks fall into the feeding channel 5 of the lens guide mold 2, and the lens blanks guided through the feeding channel 5 are finally accurately dropped into the inner hole of the metal tube shell on the tube shell positioning groove 4, completing the installation of the lens.

[0045] IV. Subsequent processing

[0046] The lens bearing mold 1 and the lens guide mold 2 are removed in turn, at this time all the metal tube shells have been installed with lenses and are retained on the tube shell positioning mold 3. Then the whole tube shell positioning mold 3 can be transferred to the heating device for subsequent sintering and curing process to form the final cap product.
