Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and in particular to an optical lens coating fixture. Background Technology

[0002] With the development of optical products, the application range of optical lenses is becoming increasingly wide. Generally speaking, manufactured optical lenses need to undergo post-processing to obtain good performance suitable for their applications. Coating is one of the important steps in this post-processing. Coating refers to depositing one or more thin films on the surface of optical elements using physical or chemical methods. This utilizes the interference effect generated at the thin film interface by incident, reflected, and transmitted light to achieve effects such as focusing, collimation, filtering, reflection, and refraction. However, the coating process for optical lenses requires the use of coating fixtures.

[0003] The existing coating fixtures have a relatively simple structure, consisting of only a slot for placing the lens. As a result, it is not easy to fix the optical lens, and it is inconvenient to remove the lens from the slot after coating, which affects the efficiency of optical lens coating.

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0020] like Figures 1-5 An optical lens coating fixture is shown, comprising a support fixture 1 and a clamping fixture 2 that can be combined. The clamping fixture 2 includes a rectangular frame 3, with clamping components on both the left and right sides of the rectangular frame 3. Each clamping component includes an elastic clamping member that can slide left and right. A plurality of clamping portions are formed between the elastic clamping member and the side wall of the rectangular frame 3. The plurality of clamping portions are spaced apart in the front-back direction. An intermediate connecting plate 4 is provided in the rectangular frame 3 and between two clamping components. A driving component that can drive the two elastic clamping members to slide against each other simultaneously is provided between the intermediate connecting plates 4. The support fixture 1 is provided with a placement groove 5 for placing the rectangular frame 3. A support column 6 for supporting the optical lens 10 is provided in the placement groove 5 and below the corresponding clamping portion.

[0021] According to the above structure, when clamping the optical lens 10, the clamping fixture 2 and the support fixture 1 can be combined first. That is, the rectangular frame 3 is placed in the placement groove 5 of the support fixture 1. At this time, the support column 6 in the placement groove 5 is located in the clamping part of the clamping fixture 2. The optical lens 10 to be coated is placed directly on the support column 6. Then, the drive component drives the two elastic clamping members to move outward. The optical lens 10 is clamped by the cooperation of the elastic clamping members and the rectangular frame 3. Finally, the clamping fixture 2 can be removed for coating, which greatly improves the stability of the optical lens during coating. In addition, after the coating is completed, the clamping fixture 2 is also placed in the placement groove 5 of the support fixture 1. The drive component drives the two elastic clamping members to release. The optical lens 10 is supported by the support column 6. Then, the clamping fixture 2 can be removed. This allows the optical lens to be removed conveniently and quickly, improving the efficiency of the coating work.

[0022] In this utility model, the elastic clamping member includes a clamping plate 21 and a sliding plate 22 arranged at left and right intervals, and a spring 23 connected between the clamping plate 21 and the sliding plate 22.

[0023] Furthermore, guide posts 31 are spaced apart on the side of the clamping plate 21 near the sliding plate 22. The guide posts 31 are movably inserted through the sliding plate 22. Two springs 23 are spaced apart and are respectively sleeved on the guide posts 31.

[0024] A slider 41 is provided at both the front and rear ends of the sliding plate 22, and a transverse groove 42 is provided on both the front and rear sides of the rectangular frame 3. The slider 41 slides in the transverse groove 42. By sliding the slider 41 in the transverse groove 42, the sliding plate 22 can be guided to slide left and right.

[0025] The clamping plate 21 is provided with an arc-shaped groove 51 for clamping the optical lens 10 on the side opposite to the rectangular frame 3, and the two opposing arc-shaped grooves 51 form a clamping part.

[0026] The driving assembly includes a rotating disk 61 rotatably mounted on the intermediate connecting plate 4. A protrusion for easy twisting is provided at the upper end of the rotating disk 61. A positioning semicircular flange 62 is symmetrically provided on the left and right sides of the outer wall of the rotating disk 61. A positioning groove 63 that cooperates with the positioning semicircular flange 62 is provided on the side of each of the two sliding plates 22 near the rotating disk 61. A tension spring 64 is spaced back and forth on the side of each of the two sliding plates 22 near the intermediate connecting plate 4. The other end of the tension spring 64 is connected to the intermediate connecting plate 4.

[0027] During operation, the rotation of the rotating disk 61 causes the positioning semicircular flange 62 to push against the sliding plate 22, driving the sliding plate 22 to move outward. Then, under the action of the spring 23, the optical lens 10 is clamped by the cooperation of the clamping plate 21 and the rectangular frame 2. When the positioning semicircular flange 62 rotates and abuts against the positioning groove 63 of the sliding plate 22, the rotating disk 61 can be positioned and fixed, improving the stability of the optical lens after clamping. Similarly, when removing the optical lens, the rotating disk 61 is turned to disengage the positioning semicircular flange 62 from the sliding plate 22. Then, under the action of the tension spring 64, the sliding plate 22 is pulled inward, thereby releasing the optical lens.

[0028] To facilitate picking up the clamping fixture 2, notches 71 are provided on all four sides of the support fixture 1.
