Description of the invention: [Technical field of invention] [0001] The present invention relates to a spheronization apparatus and a spheronization method using the same, for non-circular The rounding of the shaped workpiece. [Prior Art] [0002] In the optical industry, an optical workpiece is usually made into a circular shape, such as an infrared cutting filter of a digital camera. However, the industrial method initially cuts the formed part, which is generally square, so it is necessary to round the square workpiece to have a rounded edge to satisfy the optical application. [0003] A cylindrical grinding machine is a machine for processing workpieces of various shapes into a circular shape. The working principle is to grind a workpiece fixed by a grinding machine fixing device by a high-speed rotating grinding wheel to process it into a desired size. Round. Generally, the grinder fixing device is a pair of hollow jigs. Firstly, the air suction part of the jig is sucked by the air pump to suck the workpiece on one of the jigs, and then the other jig is brought close to fix the workpiece, and then grinded by the grinding wheel. The jig can be widely used in the rounding or rounding process of a general-shaped workpiece. However, the jig can only fix one workpiece at a time, so that only one can be ground at a time, and the productivity is too low. [0004] There has thus been a method of grinding a plurality of workpieces at a time. The method mainly utilizes a pair of jigs capable of carrying a plurality of workpieces at a time, and the workpiece is processed into a circular shape after two grindings. Please refer to the fifth figure and the sixth figure, which are conventional combination tools for spheronization, and the fixture groove is used for placing the workpiece 5 to be ground, wherein the groove 32 of the first jig 3 has two groove walls perpendicular to each other. The cross-sectional shape of the groove 42 of the second jig 4 is a semicircular shape in which the workpiece is to be rounded. First Fixture 3 and No. 094137928 Form No. A0101 Page 3 of 13 0993216975-0 1330573 June 22, 2008 Nuclear Replacement Page The two fixtures 4 are identical except for the groove shape. The spheronization process is to first put a plurality of square plate-shaped workpieces 5 into the grooves 32 of the first jig 3, and apply UV glue (ultraviolet glue) to cure the glue instantaneously by using UV lamp irradiation. The workpieces 5 are adhered together, and the workpiece 5 is polished by a grinding wheel to have a semicircular portion 52, a square portion 51 and two sharp corners 53, and then the workpiece 5 is placed in the semicircular groove of the second jig 4. In the case of 42, the square portion 51 and the two sharp corners 53 are rounded to form a complete circular workpiece. [0005] However, the above-described rounding device and the spheronization method must undergo a plurality of processes to grind the square workpiece 5 into a circular shape. Multiple processes result in longer spheronization times, which increases the cost of spheronization. SUMMARY OF THE INVENTION [0006] In view of the above circumstances, it is necessary to provide a rounding device with a short spheronization time. [0007] In addition, it is necessary to provide a spheronization method in which the spheronization process is small and the spheronization time is short.
