[0023] Reference Figure 1-Figure 4 A lens coating auxiliary fixing mechanism includes a support 1, both sides of the support 1 are fixed with a fixing plate 2 by bolts, a first through slot 11 is opened inside the fixing plate 2, a rotating shaft 6 is slidably connected inside the first through slot 11, one end of the rotating shaft 6 passes through the first through slot 11 and is fixed with a rotating rod 17 by bolts, a plurality of clamping blocks 18 are fixed on one side of the rotating rod 17 by bolts, a threaded rod 15 is rotatably connected to one side of the fixing plate 2, a slide plate 4 is threadedly connected to the outer side of the threaded rod 15, and the slide plate 4 is sleeved on the outer side of the rotating shaft 6 and is rotatably connected to the rotating shaft 6, the lens is placed horizontally between the two fixing plates 2, and then the threaded rod 15 is rotated, so that the slide plate 4 drives the rotating shaft 6 and the parts connected to the rotating shaft 6 to move inward along the first through slot 11 as a whole, Thereby, the rotating rod 17 drives the clamping block 18 to move and clamp the lens, so that the external coating device coats one side of the lens. The outer side of the rotating shaft 6 is sleeved with a torsion spring 5, and the two ends of the torsion spring 5 are respectively fixed to the slide plate 4 and the rotating shaft 6. A socket 7 is provided on the top of the rotating shaft 6. The upper surface of the slide plate 4 is fixed with a first multi-section telescopic rod 10 by bolts. The extended end of the first multi-section telescopic rod 10 is fixed with an insertion rod 8 by screws, and the insertion rod 8 is plugged into the socket 7. The insertion rod 8 is pulled upward to move it upward and out of the socket 7. At this time, the torsion spring 5 loses its restriction and resets, so that the rotating shaft 6 drives the rotating rod 17 to rotate and flip 180 degrees, and then the clamping block 18 drives the lens to turn over, which is convenient for the external coating device to coat the other side of the lens.

[0024] In the present invention, it should be noted that two grooves 12 are provided inside the fixed plate 2, and a second multi-section telescopic rod 13 is fixed inside the groove 12 by bolts. The groove 12 can avoid the second multi-section telescopic rod 13, and the second multi-section telescopic rod 13 is fixed to the slide plate 4.

The reinforcing rib 3 makes the connection between the support 1 and the fixed plate 2 more firmly.

[0025] Working principle: When the lens needs to be clamped, first place the lens horizontally between the two fixed plates 2, and then rotate the threaded rod 15, so that the slide plate 4 drives the rotating shaft 6 and the parts connected to the rotating shaft 6 to move inward along the first through groove 11 as a whole, and the second multi-section telescopic rod 13 contracts, so that the rotating rod 17 drives the clamping block 18 to move to clamp the lens, so that the external coating device coats the lens, and then pull the insertion rod 8 upward to move it upward and move out of the socket 7. At this time, the torsion spring 5 loses its restriction and resets, so that the rotating shaft 6 drives the rotating rod 17 to rotate and flip, and then the clamping block 18 drives the lens to flip over, which is convenient for the external coating device to coat the other side of the lens.
