The groove 125 is offset from the positioning post 201 on the base 20. The assembly table 12 is supported by the positioning post 201 on the base 20 such that the assembly bar 21 is at a distance from the end surface of the second boss 123 of the assembly station 12. The lens 14 is placed in the through hole 124 of the second boss 123 of the assembly table 12, and the lens barrel 15 is sleeved on the second boss 123 of the assembly table 12. The press-fit cover 13 is press-fitted to the lens barrel 15 for fixing the lens barrel 15. By rotating the assembly table 12, the groove 125 on the assembly pedestal 121 is aligned with the positioning post 201 on the base 20, and the assembly table 12 is gently lowered to match the groove 125 with the positioning post 201, so the assembly rod 21 is assembled on the assembly table. The length in the through hole 124 is elongated such that the spherical surface 210 of the end of the assembled rod 21 is in full contact with the lens 14 to assemble the lens 14 into the lens barrel 15.

使用所述鏡片組裝裝置將鏡片組裝進鏡筒中，由於先將鏡片置於與其配合之組裝台凸台之通孔內，又組裝棒端 部球面之曲率與鏡片之曲率相同，所以可使鏡片完全貼附承靠於組裝棒之端部，調節組裝棒之長度將鏡片組裝進鏡筒，所以使用該種方法能使鏡片之組裝相當精確，鏡片之光軸精准，減少光軸偏移之機會，能提高鏡頭之生產性及製造良率。 The lens assembly device is used to assemble the lens into the lens barrel, and the rod end is assembled by first placing the lens in the through hole of the assembly table boss with which it is matched. The curvature of the spherical surface is the same as the curvature of the lens, so that the lens can be completely attached to the end of the assembled rod, and the length of the assembled rod is adjusted to assemble the lens into the lens barrel, so the assembly of the lens can be quite accurate using this method. The optical axis of the lens is accurate, reducing the chance of optical axis shift, which can improve the productivity and manufacturing yield of the lens.
