Description

Technical Field

[0001] This utility model belongs to the field of curing device technology, and in particular relates to an ultraviolet curing device for lens bonding. Background Technology

[0002] UV curing is a photochemical reaction, similar to traditional drying processes, but the principles differ. Traditional drying typically relies on the evaporation of solvents in the coating material to achieve hardening, while UV curing crosslinking does not involve solvent evaporation. UV curing is a type of radiation curing, which utilizes electromagnetic radiation to produce reactions such as radiation polymerization and radiation crosslinking. It is a chemical process that rapidly transforms low-molecular-weight substances into high-molecular-weight products. The system contains no solvent or only a very small amount of solvent, and the liquid film is almost 100% cured after irradiation, resulting in very low VOC emissions.

[0003] In the lens manufacturing process, bonding is a crucial step. Traditional UV curing equipment may allow dust or impurities to fall onto the lens surface during bonding. This dust and impurities can affect the curing effect of the adhesive, leading to decreased bonding strength or even delamination. Furthermore, the worktable of traditional UV curing equipment is usually fixed, which cannot accommodate the bonding needs of lenses of different sizes and shapes, thus limiting the applicability of the equipment.

[0004] To address these issues, we provide a UV curing apparatus for lens bonding. Utility Model Content

[0005] The purpose of this invention is to provide a UV curing device for lens bonding. By combining the cleaning component and the placement component, it solves the problems of existing UV curing devices lacking cleaning function and being unable to adapt to the bonding needs of lenses of different sizes and shapes.

[0010] The present invention is further configured such that both ends of the first and second slide rods are fixedly connected to the inner wall of the placement box, and one end of the first and second lead screws are fixedly connected to the inner wall of the placement box through bearings.

[0032] Specifically: The placement box 11 and the box door 12 can form a relatively sealed environment, reducing the entry of external dust and other impurities and ensuring the purity of the curing process.

[0033] The working principle of this utility model is as follows: By activating the electric push rod 42, the electric push rod 42 drives the rotary motor 43 and the drive gear 44 to move. The drive gear 44 meshes with the driven gear 49. Then, by activating the rotary motor 43, the rotary motor 43 drives the drive gear 44 to rotate, which in turn drives the driven gear 49 to rotate. The driven gear 49 then drives the drive belt pulley 48 to rotate. The drive belt pulley 48, through a belt, drives the driven belt pulley 26 to rotate. 6 drives the lead screw 25 to rotate, which in turn drives the cleaning and dust-collecting brush 22 via the connecting block 23 to clean and vacuum the dust at the bottom of the UV curing lamp 14. Simultaneously, the vacuum cleaner 21 removes the swept dust. After cleaning, open the door 12, then turn the handwheel to drive the worm gear 344, which in turn drives the worm wheel 343, which in turn drives the lead screw 341. The lead screw 341 then moves the two clamping plates 342 relative to each other until they reach a suitable position. After positioning, place the lens to be cured between the two clamps 342, and then continue to rotate the handwheel to fix the lens. Then, start the electric push rod 13, which drives the UV curing lamp 14 to move downward to the appropriate position, and then turn on the UV curing lamp 14 to perform the curing work. Then, retract the electric push rod 2 42, which drives the rotary motor 43 to return to its original position. At this time, the drive gear 44 meshes with the driven gear 1 45, which drives the drive belt pulley 1 47 to rotate. The drive belt pulley 1 47 drives the driven belt pulley 2 37 to rotate via the belt. The driven belt pulley 2 37 drives the lead screw 2 36 to rotate, and the lead screw 2 36 drives the moving seat 31 to move. The moving seat 31 can then move the lens through the placement seat 33 and the clamp 34, thus achieving good curing. At the same time, start the drive motor 32, which drives the placement seat 33 to rotate. The placement seat 33 drives the lens to rotate through the clamp 34, ensuring the uniformity of light received by the lens.
