[0016] In order to make the purpose, technical scheme and beneficial effect of the utility model more clear, the preferred embodiment of the utility model will be explained in detail below in combination with the drawings, so as to facilitate the understanding of the technical personnel.
[0017] The utility model discloses a lens clamping structure for lens coating, one kind of lens clamping structure for lens coating mainly includes connecting axle 1, sleeve ring 2, connecting plate 3, clamping elastic sheet 4, locking bolt 5, sleeve ring 2 fixed mounting is in connecting axle 1, is distributed on connecting axle 1 at equal intervals, connecting plate 3 is fixedly installed with sleeve ring 2, is installed on the outer circumferential surface of sleeve ring 2 at equal intervals, is equipped with the threaded hole on sleeve ring 2, connecting plate 3, locking bolt 5 is connected with threaded hole and installs clamping elastic sheet 4 on connecting plate 3.
[0018] As Figure 2 , Figure 3As shown, the clamping spring 4 includes a fixed mounting portion 41, an elastic deformation portion 42, and a limiting stop edge 43. The fixed mounting portion 41 is mounted on the connecting plate 3 by a locking bolt 5. The elastic deformation portion 42 is mounted on both ends of the fixed mounting portion 41. The limiting stop edge 43 is mounted on the end of the elastic deformation portion 42. The elastic deformation portion 42 has a certain elasticity, which can adapt to the size of the lens and provide appropriate clamping force, so as to clamp the lens. The limiting stop edge 43 can prevent the lens from slipping during clamping.
[0019] As shown in Figure 2 , Figure 3 , the folding edge direction structures of the limiting stop edges 43 at the upper and lower ends of the elastic deformation portion 42 are opposite and are set as a symmetrical structure. The limiting stop edges 43 are bent to form a circular arc structure. The folding edge direction structures of the limiting stop edges 43 at the upper and lower ends of the elastic deformation portion 42 are opposite and are bent to form a circular arc structure. This can make the clamping spring 4 better fit the shape of the lens edge when clamping the lens, and ensure the stability of the lens.
[0020] As shown in Figure 2 , Figure 3 , the elastic deformation portion 42 and the fixed mounting portion 41 are integrally formed, and an angle is clamped between the elastic deformation portion 42 and the fixed mounting portion 41. The clamping spring 4 has a certain elastic deformation ability and can adapt to lenses of different sizes and shapes. The profile of the lens is adapted by the deformation of the elastic deformation portion 42, and a wider clamping range is achieved.
[0021] As shown in Figure 2 , Figure 3 , the elastic deformation portion 42 has two wing plates 421, and the two wing plates 421 are bifurcated to form a gap. This helps to increase the flexibility and adaptability of the elastic deformation portion 42, so that it can better fit the surface of the lens.
[0022] Working process:
[0023] Before clamping the lens, first install the connecting shaft 1 on the coating equipment, and ensure the stability of the connecting shaft, then adjust the clamping spring 4 according to the size and shape of the lens, since the clamping spring 4 is installed on the connecting plate 3 by the fixed mounting part 41 with the locking bolt 5, the operator can loosen the locking bolt 5 to adjust the position and angle of the clamping spring 4, after adjustment, lock the clamping spring 4, place the lens to be coated between the upper and lower elastic deformation parts 42, since the sleeve ring 2 is fixed on the connecting shaft 1 and is distributed at equal intervals, the connecting plate 3 is also installed on the outer circumferential surface of the sleeve ring 2 at equal intervals, which provides multiple positions for the lens to be placed and fixed, the operator can adjust the opening degree of the upper and lower elastic deformation parts 42 according to the curvature and other factors of the lens, and utilize the characteristics of the elastic deformation part 42, since the elastic deformation part 42 is elastic, it can adapt to the shape of the lens and tightly adhere to the lens, the limiting stop 43 at the lower end of the elastic deformation part 42 is bent upward, and the limiting stop 43 at the upper end is bent downward, during clamping, the limiting stop 43 will limit the lens from the upper and lower edges of the lens to prevent the lens from shifting in the upward and downward directions during clamping, at the same time, the circular arc structure of the limiting stop 43 can better fit the arc shape of the lens edge, ensuring the stability of clamping and the protection of the lens.
