The automatic lens grinding device of this embodiment basically has three pairs The lens is processed into a lens mode. The first mode is single-sided single-axis machining mode, the second mode is single-sided multi-axis machining mode, and the third mode is double-sided machining mode. The following modes are explained one by one: When the automatic polishing apparatus is set to the single-sided single-axis processing mode, that is, each polishing unit 1 independently processes the lens to become a lens, and the feeding table 2 transmits the lens to each polishing unit 1. When the polishing unit 1 of the present embodiment grinds the lens in this mode, as shown in Fig. 6, the rough embryo lens A is placed on the second coarse embryo holder 22, and is slid on the slider 21 to be sent to each The grinding unit 1 is conveyed to the leftmost grinding unit 1 as shown in the figure, and as shown in Fig. 6, the swing arm 3 has been positioned in the first position and returned to the second figure. The first suction cup 51 of the first reclaiming mechanism 5 sucks and displaces the coarse embryo lens A located on the second coarse embryo holder 22, so that the rough embryo lens A is placed as shown in FIG. 7(a). On the first coarse embryo holder 321 of the swing arm 3, then the swing arm 3 is swung to the second position as shown in FIG. 7(b), and the second suction cup 61 of the second reclaiming mechanism 6 is thick. The embryonic lens A is taken out from the first coarse embryo holder 321 and the roughing lens A can be polished by the grinding mechanism 4. When the rough lens A is ground, the rough lens B is already in the second of the feeding table 2. The rough embryo bearing 22 is waiting. After the swing arm 3 transmits the rough embryo lens A, the swing arm 3 returns from the second position to the first position, and then the second suction head 51 of the first reclaiming mechanism 5 can be used to transfer the second coarse embryo. The rough embryo lens B on the seat 22 is taken out and sent to the first coarse embryo holder 321 for preparation.

As shown in FIG. 7(c), when the rough embryo lens A is ground into the lens finished product A, the second suction cup 61 of the second reclaiming mechanism 6 is used to The lens finished product A is taken out, and then the swing arm 3 is first swung from the first position to the third position, so that the second reclaiming mechanism 6 places the lens finished product A on the first finished product holder 322, and then the swing arm 3 is further From the third position swinging back to the second position (as shown in (b) of FIG. 7), the second reclaiming mechanism 6 further passes the rough embryo lens B from the first coarse embryo holder 321 by the second suction cup 61. It is taken out and ground by the grinding mechanism 4, at which time the swing arm 3 is then swung back to the first position as shown in Fig. 7(d). Further, as shown in FIG. 3 and FIG. 7(e), at this time, the lens product A is taken out from the first finished holder 322 by the first suction cup 51 of the first reclaiming mechanism 5 and placed in the second. The finished holder 23, the other first suction cup 51 at this time, the other coarse embryo lens C is placed on the second coarse embryo holder 22, and the first retracting mechanism 55 is returned while the coarse embryo lens C is placed. Prepared on the first rough embryo holder 321 , and the lens finished product A is sent out by the feeding table 2 for cleaning and storage, and repeated by the actions shown in (a) to (e) of FIG. 7 to complete the order. Automated lens grinding in single-axis machining mode.

As shown in FIG. 8, when the automatic polishing apparatus of the present embodiment is set to the single-sided multi-axis machining mode, the rough embryo lens must be sequentially polished to the same surface through the four polishing units 1. As shown in FIG. 9(a), at the start of the grinding, the roughing lens D is also moved to the position of the grinding mechanism 4 by the feeding table 2, and the coarse embryo is passed through the first suction cup 51 of the first reclaiming mechanism 5. The lens D is moved by the second coarse embryo holder 23 onto the first rough embryo holder 321, and as shown in FIG. 9(b), the rough lens D is swung from the first position to the second through the swing arm 3. The position is polished by the grinding mechanism 4; as shown in (c) of FIG. 9, the rough lens D is ground by the grinding mechanism 4 It is a lens blank D, and as shown in FIG. 9(d), is swung by the swing arm 3 to the lens grinding center 41 of the grinding mechanism 4 of the other grinding unit 1, and as shown in FIG. 10(a) The lens blank semi-finished product D is taken out by the second suction cup 61 of the second reclaiming mechanism 6 of the other polishing unit 1, and the second grinding is performed by the polishing mechanism 4 of the other polishing unit 1, and the second grinding is performed. After completion, as shown in FIG. 10(b), the lens blank 3 is received by the swing arm 3 of the other polishing unit 1, and is sequentially ground by the four grinding units 1 in order to complete one-sided operation. Axis machining mode.

When the automatic polishing apparatus of the embodiment is set to the double-side processing mode, the rough embryo lens must also be sequentially polished to the same surface through the four polishing units 1. The polishing operation is in principle different from the single-sided multi-axis processing mode. The lens must be turned over during the grinding process so that both sides of the lens are ground. Please refer to Figures 8, 11 to 12. If it is the first double-sided processing mode, the coarse-grained lens E is mainly the first group of polishing units 1 from the left side to complete the grinding operation and become the lens semi-finished product E. Performing the grinding of the polishing unit 1 of the second group, and turning the surface after the third group of polishing units 1 is finished grinding, and then grinding the fourth group of polishing units 1 to complete; if it is another double-sided processing mode, the main system is thick After the polishing unit 1 of the first group from the left side completes the polishing operation and becomes the lens semi-finished product E, the grinding operation of the polishing unit 1 of the second group is performed, and when the second group of polishing units 1 finishes grinding, the surface is turned over, and then The grinding of the third and fourth sets of the grinding unit 1 is performed to completion, but the turning operation is the same regardless of the double-sided processing mode. As shown in Figures 11 to 12, when the lens semi-finished product E is turned over, The lens blank E is taken out from the first rough blank holder 321 by the first suction cup 51 of the first reclaiming mechanism 5, and moved to the flip seat 7, and the lens semi-finished product E is fixed by the flip seat 7 and then flipped 180 degrees. After the inversion is completed, the lens blank E is taken out from the inverting seat 7 through the first suction cup 51 of the first reclaiming mechanism 5, and then moved to the first rough bobbin holder 321 for successive grinding operations.

It is not difficult to find the advantages of the present invention from the above description, in that the polishing unit 1 can automatically grind the lens to become a finished lens, and the manner of grinding can be changed according to the setting, so as to meet the requirements of various lenses, the process is not required. Compared with the conventional grinding device, the lens grinding device of the present invention can achieve labor cost savings by automation, and can accurately control the process by automated operations, thereby eliminating human error. In turn, the overall efficiency of the lens polishing process is improved.
