Description of the Invention: [Technical Field] [0001] The present invention relates to a rounding jig, and more particularly to a rounding jig for facilitating alignment in a rounding process. [Prior Art] [0002] Circular lenses have a wide range of applications. For example, in a digital camera module for a mobile phone, it is usually necessary to add a light-passing sheet to make the image clearer. Since the lens barrel is mostly circular, each tube is in the lens barrel. Group parts such as filters are also often circular. In the prior art, the process of the circular filter is usually to cut the mother film Φ of the film into a small square shape by a cutting machine, and then round it by a rounding machine. In the spheronization process, a single multi-piece is usually used. The specific method is as follows: before performing rounding, a plurality of square filters are glued together, and then the glued filter column is fixed on a jig, and the glue is filtered by a grinding wheel of a grinding machine. The light column column has its outer diameter squared to the desired circular shape. Therefore, in the above spheronization process, the alignment relationship between the jig and the grinding wheel has a great influence on the yield of the spheronized process product. ^ [0003] The prior art relates to the alignment between the rounding jig and the grinding wheel. The usual practice is to judge the alignment by the human eye. This method has a large error, which results in a low yield of the round-rolling process product. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a alignable rounding jig. [0005] A rounding jig includes a jig body, a joint portion, and a positioning pin, wherein the jig body has a working surface, the working surface is provided with a groove, and the joint portion is closed One end of the jig body of the groove is connected, and the positioning pin is disposed on the joint portion. 094123172 Form No. A0101 Page 3 of 13 0993348103-0 1352646 September 29, 1999, Nuclear Replacement Page [0006] Compared with the prior art, the rounding fixture is provided with a pair of positioning devices at one end of the fixture body.
