Description

Technical Field

[0001] The utility model relates to the technical field of optical lens coating, in particular to an optical lens coating device. Background Art

[0002] Optical lens coating is a crucial process. It coats the surface of the optical lens with one or more layers of metal or other dielectric films to reduce or increase light reflection, beam splitting, color separation, light filtering, etc. This coating technology is of great significance for improving the performance of optical lenses and expanding their application range.

[0003] With the continuous development of optical technology, the requirements for optical lens coating technology are becoming higher and higher. Although traditional coating devices can achieve basic coating functions, they still have certain limitations in some aspects. For example, an optical lens coating device disclosed in the announcement number "CN219195116U" is conducive to placing multiple groups of optical lenses at one time through a discharge tray with a truncated cone shape structure, thereby improving the coating efficiency of the optical lenses. However, when this device processes optical lenses that require double-sided coating, workers are required to turn over the lenses on the discharge tray one by one, which affects the overall efficiency of the coating process. Therefore, we propose an optical lens coating device that can automatically flip the lenses. Utility Model Content

The motor 8 is fixedly installed at the inner bottom of the constant temperature and pressure box 1, and a driving gear 9 is fixedly installed on the top of the output shaft of the motor 8. The teeth on the driving gear 9 are aligned with the teeth on the driving gear 9. The teeth on the inner gear ring of the rotating disk 6 are meshed, and the motor 8 is operated. Its output shaft can drive the driving gear 9 to drive the gear ring inside the rotating disk 6, so that the rotating disk 6 rotates on the disk seat 7. A fixed rod 10 is set at the inner center of the rotating disk 6. The bottom of the fixed rod 10 is fixedly connected to the inner bottom of the constant temperature and pressure box 1. A support frame 11 is rotatably installed on the top of the fixed rod 10. U-shaped card grooves are arranged in a circular array at equal distances around the support frame 11. A second bevel gear 12 is welded on the top of the fixed rod 10. A transfer unit 5 is arranged on the top of the rotating disk 6. The transfer unit 5 is provided with eight groups. The transfer units 5 are arranged in a circular array at equal distances on the top of the rotating disk 6. The transfer unit 5 consists of a lens frame 51, a connecting shaft 52, a first bevel gear 53, The lens frame 51 is composed of a connecting block 54, a pin shaft 55, a supporting block 56, a lens groove 57, a pressing ring 58 and a supporting ring 59. The lens frame 51 is a "trapezoidal" structure. A plurality of lens grooves 57 are arranged in an array in the middle of the lens frame 51. Supporting rings 59 are arranged at the inner bottom of the lens groove 57. The supporting rings 59 can support the optical lenses placed in the lens groove 57. Pressing rings 58 are respectively threadedly installed on the inner top of the lens groove 57. An annular silicone pad is arranged at the bottom of the pressing ring 58 to ensure that the pressing ring 58 does not damage the lens when pressing the lens. Connecting shafts 52 are respectively welded in the middle of the upper and lower ends of the lens frame 51, and the connecting shaft 52 located at the upper end of the lens frame 51 is correspondingly movably mounted in the U-shaped slot at one end of the support frame 11.

The bottoms of the support blocks 56 are respectively fixedly connected to the top of the rotating disk 6. As the rotating disk 6 rotates, when one group of lens frames 51 rotates to the front of the second bevel gear 12, the teeth on the first bevel gear 53 at the top of the lens frame 51 mesh with the teeth at the front end of the second bevel gear 12. At this time, the rotation of the first bevel gear 53 will drive the lens frame 51 to rotate on the support frame 11.Thus, double-sided coating of optical lenses is realized, and a controller 3 is also included. The controller 3 is arranged at the front end of the top right side of the constant temperature and constant pressure box 1, and the controller 3 is electrically connected to the coating machine 4, the motor 8 and the external power supply.

[0020] The working principle of the utility model is as follows: when in use, first open the box door 2, then pull up the lens frame 51, and the connecting shaft 52 at the bottom of the lens frame 51 drives the connecting block 54 to rotate axially along the pin shaft 55. After the lens frame 51 is pulled up, the staff can put the optical lenses that need to be plated into the lens grooves 57 respectively, so that the supporting rings 59 inside the lens can support the optical lenses, and then the pressing rings 58 are respectively threadedly installed on the inner sides of the lens grooves 57 until the annular silicone pad at the bottom of the pressing ring 58 contacts the surface of the optical lens, thereby completing the fixation of the lens and ensuring its stability during the coating process, and then push the lens frame 51 back to its original position, so that the connecting shaft 52 at the top of the lens frame 51 is movably mounted in the corresponding U-shaped slot on the support frame 11; then, the staff can start the motor 8 through the controller 3, so that the output shaft of the motor 8 drives the driving gear 9 to drive the gear ring inside the rotating disk 6 to rotate, and move the lens frames 51 on the rotating disk 6 that are not equipped with optical lenses to the front. side, so that it is convenient for the staff to supplement the optical lenses that have not been installed. In addition, since the connecting shaft 52 at the top of the lens frame 51 is movably connected with the U-shaped groove on the support frame 11, when the rotating disk 6 drives the lens frame 51 to rotate, the support frame 11 rotates along the fixing rod 10; after completing the fixing of the lens, the box door 2 is closed, and the coating machine 4 is started. The coating machine 4 inside the device is the same as that in the reference document "CN219195116U", and can be directly used in the device. As the motor 8 drives the driving gear 9 to drive the rotating disk 6 to rotate continuously, when one group of lens frames 51 rotates to the front of the second bevel gear 12, the teeth on the first bevel gear 53 at the top of the lens frame 51 are meshed with the teeth at the front end of the second bevel gear 12. At this time, the rotation of the first bevel gear 53 will drive the lens frame 51 to rotate on the support frame 11, thereby realizing double-sided coating of the optical lens. Since the lens frame 51 is flipped, the coating machine 4 can simultaneously coat the front and back sides of the optical lens.
