The second suction cup 61 of the second recovery device 6 takes out the lens A ′ before polishing from the first front end mounting portion 321 and the polishing device 4 polishes the lens A ′ before polishing. At the same time as the lens A ′ before polishing is polished, the lens B before polishing is placed on the second front end mounting portion 22 of the supply base 2. The swing arm 3 returns from the second position to the first position after conveying the lens A ′ before polishing. At the same time, the first suction cup 51 of the first recovery device 5 takes out the lens B before polishing of the second front end placement part 22 and conveys it to the first front end placement part 321 for preparation.

  As shown in FIG. 7C, when the lens A ′ before polishing is polished to finish the lens product A, the second suction cup 61 of the second recovery device 6 takes out the lens product A. The swing arm 3 swings from the first position to the third position, and the second retrieval device 6 places the lens product A on the first rear end placement portion 322. Subsequently, the swing arm 3 swings from the third position to the second position (see FIG. 7B), and the second recovery device 6 uses the second suction cup 61 to attach the lens B before polishing to the first front end placement portion 321. Take out from. At the same time as the polishing is performed by the polishing apparatus 4, the swing arm 3 swings back to the first position as shown in FIG. As shown in FIG. 3 and FIG. 7E, the first suction cup 51 of the first recovery device 5 takes out the lens product A from the first rear end mounting portion 322 and puts it on the second rear end mounting portion 23.

The other first suction cup 51 takes out the other unpolished lens C placed on the second front end mounting portion 22, and at the same time as the first recovery device 55 returns, the unpolished lens C is mounted on the first front end mounting. It is placed on the mounting portion 321 and preparation is performed. The lens product A is moved from the supply base 2 to a cleaning operation and a storage operation. The operations shown in FIGS. 7A to 7E are repeated to complete the automated lens polishing operation in the single-surface single-axis processing mode.

  Further, as shown in FIG. 8, when the setting of the polishing apparatus is the single-surface multi-axis processing mode, the lens before polishing is polished on the same surface through the four polishing units 1 in order. 9A, at the start of polishing, the lens D ′ before polishing is moved to the position of the polishing device 4 by the supply base 2, and the lens D before polishing by the first suction cup 51 of the first recovery device 5 is used. 'Moves from the second front end mounting part 23 to the first front end mounting part 321. As shown in FIG. 9B, the lens D ′ before polishing is swung from the first position to the second position by the swing arm 3, and polishing processing is performed by the polishing device 4. As shown in FIG. 9C, the lens D ′ before polishing is polished by the polishing apparatus 4 to become a lens semi-finished product D. That is, as shown in FIG. 9 (d), the swing arm 3 is swung until it is aimed at the polishing center 41 of the lens of the polishing apparatus 4 of the other polishing unit 1, and as shown in FIG. 10 (a). The lens semi-finished product D is taken out by the second suction cup 61 of the second recovery device 6 of the other polishing unit 1, and the polishing device 4 of the other polishing unit 1 performs the second polishing. After completion of the second polishing, as shown in FIG. 10B, the lens semi-finished product D is delivered to the swing arm 3 of the other polishing unit 1 and is polished by the four polishing units 1 in the order of operation. Complete single-side multi-axis machining mode.

  When the setting of the polishing apparatus is the double-sided processing mode, the lens before polishing similarly passes through the four polishing units 1 in order, and the same surface is polished. Polishing is basically the same as the single-sided and multi-axis processing mode, and the difference is that the lens needs to be turned over in the polishing process, and polishing is performed on both surfaces of the lens. As shown in FIGS. 8, 11 and 12, in the first double-sided processing mode, the lens E ′ before polishing becomes a lens semi-finished product E after being polished by the first set of polishing units 1 starting from the left side. After being turned over, polishing is performed by the second set of polishing units 1, and when polishing by the third set of polishing units 1 is completed, it is turned over again and polishing by the fourth set of polishing units 1 is performed. In the other double-sided processing mode, the lens E ′ before polishing becomes a lens semi-finished product E after polishing by the first set of polishing units 1 starting from the left side, and is polished by the second set of polishing units 1. After the polishing by the second set of polishing units 1 is completed, the third set and the fourth set of polishing units 1 are polished. The reverse operation is the same in any double-sided processing mode. According to FIGS. 11 and 12, when the lens semi-finished product E is turned over, the lens semi-finished product E is taken out from the first front end mounting portion 321 by the first suction cup 51 of the first recovery device 5 and transferred to the reversing table 7. After that, the lens semi-finished product E is fixed by the reversing table 7 and then rotated 180 degrees. When the rotation is completed, the lens semi-finished product E is taken out from the reversing table 7 by the first suction cup 51 of the first recovery device 5, moved to the first front end mounting portion 321 and subjected to subsequent polishing.

  The advantages of the present invention are as follows. The polishing unit 1 automatically polishes the lens before polishing to finish a lens product. The setting of the polishing method can be changed, and the lens manufacturing process does not have to be the same. Therefore, while the conventional polishing apparatus requires the operation of an operating engineer, the lens polishing apparatus according to the present invention can save human cost by automation. Therefore, human error can be eliminated by precise control of the manufacturing process by automation work, and the efficiency of the entire lens polishing manufacturing process can be improved.
