Description

Technical Field

[0001] The utility model relates to the technical field of lens coating devices, and specifically relates to a light-curing multi-point defocus lens coating device. Background Technique

[0002] The light-curing multi-point defocus lens is a specially designed lens. By distributing multiple microlens structures on the lens surface, while providing clear vision, it can generate myopic defocus signals to achieve the effect of controlling the progression of myopia. This lens utilizes the optical principle to attempt to form myopic defocus in front of the retina, thereby affecting the growth and development of the eyeball and slowing down the deepening speed of myopia. When coating the lens, it is usually necessary to use a coating disk to sequentially fix the lens to be coated on the outer wall of the coating disk through a fixture. The existing fixture for clamping the lens has a relatively simple structure. Generally, it elastically clamps the outer walls of both sides of the lens through a C-shaped metal buckle. After installing the lens, the stability is poor. The elastic property of the metal buckle is used to cooperatively clamp the outer walls of the left and right sides of the lens. Since the lens shakes back and forth during the coating process, there is a certain probability that the lens will fall off, which is not convenient for improving the working stability of the equipment.

[0026] The specific usage scenario of this embodiment is as follows: By turning on the motor 230, the motor 230 can drive the rotating shaft 220 to rotate, so that the rotating shaft 220 can drive the clamping bin 200 to rotate and adjust the tilt angle, thereby facilitating the adjustment of the angle of the lens 300 when coating the lens 300.

[0027] Embodiment 3: As Figure 4 and Figure 5 , through holes are formed in the inner walls on both the left and right sides of the clamping bin 200.
