The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 A lens coating positioning mechanism includes a base plate 1, a plurality of mounting holes are opened inside the base plate 1, a base 4 is welded in the mounting holes, the top of the base 4 is rotatably connected to the bevel gear ring 2, the inside of the base 4 is rotatably connected to the threaded sleeve 19, one end of the threaded sleeve 19 passes through the base 4 and is welded with a bevel gear 3, and the bevel gear ring 2 is meshed with the bevel gear ring 2, the threaded sleeve 19 is internally threaded with a threaded rod 18, one end of the threaded rod 18 is fixed with a clamping block 14 by a bolt, the inside of the clamping block 14 is opened with a avoidance groove 13, the inner side of the avoidance groove 13 is rotatably connected to two connecting rods 17, the staff places the lens in the middle position inside the bevel gear ring 2, and then rotates the bevel gear ring 2 to make It drives multiple bevel gears 3 to rotate, and at the same time, the rotation of the bevel gear 3 causes the threaded sleeve 19 to rotate, so that the threaded rod 18 drives the clamping block 14 and the connecting rod 17 to move inward respectively. A second spring 15 is welded between the two connecting rods 17. One end of the connecting rod 17 is rotatably connected to the contact wheel 16. The connecting rod 17 drives the contact wheel 16 to move until the contact wheel 16 contacts the lens, and then the threaded rod 18 continues to move so that the contact wheel 16 is squeezed by the lens. At this time, the second spring 15 extends, and then the threaded rod 18 continues to move until the clamping block 14 contacts the lens, thereby allowing the lens to quickly obtain double positioning. An adjustable limiting component that limits the movement of the bevel gear ring 2 is installed on one side of the base 4.

[0025] In the present utility model, it should be noted that the limiting component includes an L-shaped support frame 12, which is fixed to the outer wall of one side of the base 4 by bolts, and a sliding sleeve 6 is fixed to the top of the L-shaped support frame 12 by bolts, and one end of the sliding sleeve 6 is inserted and slidably connected to the sliding rod 5, and one end of the sliding rod 5 passes through the sliding sleeve 6 and is welded with a clamping block 9. The circumferential outer wall of the bevel gear ring 2 is provided with a plurality of clamping grooves 10, and the clamping block 9 is clamped with the clamping groove 10. The inside of the sliding sleeve 6 is slidably connected to the disc, and the outer side of the sliding rod 5 is sleeved with a first spring 11, and the two ends of the first spring 11 are respectively fixed to the sliding sleeve 6 and the disc, and a shift rod 8 is welded to the top of the disc, and a sliding groove 7 is provided on the top of the sliding sleeve 6, and the shift rod 8 is slidably connected to the sliding groove 7. Pull the shift rod 8 so that it moves along the sliding groove 7 The first spring 11 contracts until the block 9 is completely moved out of the slot 10. A clamping groove connected to the slide slot 7 is provided on the top of the slide sleeve 6. When the position of the shift rod 8 corresponds to the position of the clamping groove, the shift rod 8 is rotated to make it fit into the clamping groove, thereby fixing the position of the block 9. At this time, the bevel gear ring 2 loses its restriction, and the clamping groove can be engaged with the shift rod 8. The clamping groove can position the shift rod 8 after moving, which is convenient for subsequent staff to rotate the bevel gear ring 2. The internal plug-in sliding connection of the base 4 is equipped with multiple guide rods 20, and the guide rods 20 are fixed to the clamping block 14. The guide rods 20 can guide the clamping block 14 so that it can move stably. The second spring 15 is located inside the avoidance groove 13.

[0026] Working principle: When it is necessary to clamp the coated lens, first pull the lever 8 to move it along the slide groove 7. At the same time, the slide rod 5 and the disc move in the slide sleeve 6. The first spring 11 contracts until the block 9 is completely moved out of the slot 10. When the lever 8 corresponds to the position of the clamping slot, rotate the lever 8 to make it clamp into the clamping slot, thereby fixing the position of the block 9. At this time, the bevel gear ring 2 loses its restriction, and the staff places the lens in the middle position inside the bevel gear ring 2, and then rotates the bevel gear ring 2 to drive multiple bevel gears 3 to rotate. At the same time, the rotation of the bevel gear 3 rotates the threaded sleeve 19, so that the threaded rod 18 drives the clamping block 14 to move to the inner position respectively, and then the connecting rod 17 drives the contact wheel 16 to move and contact the lens, and then the threaded rod 18 continues to move so that the contact wheel 16 is squeezed by the lens. At this time, the second spring 15 extends, and then the threaded rod 18 continues to move until the clamping block 14 contacts the lens, so that the lens is doubly positioned, and then the block 9 is reinserted into the slot 10 at the corresponding position.
