Rolling device and method

Abstract

The invention relates to a rounding device which can be used to round a plate-shaped or a slice-shaped work piece, including a fixture, a rounding part, a drive device and a machine table. The fixture comprises a first fixture and a second fixture which is arranged oppositely to first clamper, the fixtures are used to clamp an awaiting work piece to be rounded. The rounding part comprises a grinding surface which is used to round the awaiting work piece to be rounded. The drive device comprises a transmission device, and a first drive device and a second drive device which are connected with the transmission device. The first drive device is used to drive the transmission device and the second drive device is also connected with the work piece to be rounded, so as to adjust the distance between the rounding part and the awaiting work piece to be rounded, drive the self-rotation of the rounding part, and drive the the rounding part rotating around the fixture axis. The machine table is used to place the fixture, the drive device and the rounding part. The invention also provides a method for rounding a work piece. The rounding device of the technical proposal does not need to change grinding wheels of different sizes when rounding a work piece, thereby improving the producing efficiency and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of rounding, in particular to a rounding device and a rounding method. Background technique [0002] A few days ago, in order to avoid the color distortion of images taken by imaging devices such as digital cameras and video cameras, optical filters are usually placed in the lens modules of imaging devices, see literature: A widely tunable optical filter using ladder-type structure; S.Matsuo, Y. Yoshikuni, T. Segawa; Y. Ohiso, H. Okamoto; NTT Photonics Labs, Kanagawa, Japan; Photonics Technology Letters, IEEE; Volume 15, Issue 8, Aug. 2003, pages 1114-1116. Since the lens barrel of an imaging device is generally circular, in order to match the shape and cross-sectional size of the lens barrel, it is necessary to set the filter to a circular shape of a corresponding size. [0003] The production process of the optical filter includes firstly coating a large piece of glass with a filter film, then cutting the...

Problems solved by technology

Since the size of the semicircular grinding wheel and the distance from the filter to be rounded are fixed, if you want to make circular filter products of different sizes, you need different size grinding wheels, which leads to the need to configure according to the size of the finished circular filter A series of grinding wheels of different sizes, and the need to change the grinding wheel during the rounding process of the finished circular filter, resulting in higher production costs and lower production efficiency
