Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a coated lens and a combination lens. Background Technology

[0002] With increasing demands for image quality in lenses, current technologies often employ ink coating to eliminate stray light. The conventional approach involves applying an ink layer to the entire non-effective diameter section of the lens element, typically using a sponge soaked in ink to apply it around the entire circumference. However, due to limitations in the precision of the ink coating fixtures and equipment, and the need to ensure complete coverage without any gaps, ink accumulation and uneven application often occur after one circumference. This can lead to lens tilting or excessive air gaps after assembly, or improper bonding when used with bonded lenses. Utility Model Content

[0003] The purpose of this invention is to provide an ink-coated lens and a combination lens, which improves the uniformity of ink coating and avoids problems such as tilting or inadequate bonding during assembly.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Coated lenses, including:

[0006] First effective diameter;

[0007] A first non-effective diameter portion is disposed around the outer periphery of the first effective diameter portion. At least one side of the first non-effective diameter portion is configured as an ink coating area. The ink coating area is coated with ink to form an ink layer. The ink coating area is provided with a first recessed groove. The first recessed groove extends through the ink coating area radially along the ink coating lens. The depth of the first recessed groove is greater than the thickness of the ink layer.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figures 1-4 As shown, this embodiment of the present invention provides an ink-coated lens 1, which includes a first effective diameter portion 11 and a first non-effective diameter portion 12 surrounding the outer periphery of the first effective diameter portion 11. In order to improve the imaging quality, at least one side of the first non-effective diameter portion 12 of the ink-coated lens 1 is provided as an ink-coating area 121, and ink is coated on the ink-coating area 121 to form an ink layer.

[0039] Furthermore, to prevent ink accumulation, a first recessed groove 1211 is provided on the side of the first non-effective diameter portion 12 on which the ink layer is provided. The first recessed groove 1211 extends radially through the first non-effective diameter portion 12, that is, through the ink coating area 121, to ensure that there is no ink accumulation in the entire ink coating area 121 during ink coating. Moreover, the depth of the first recessed groove 1211 is greater than the thickness of the ink layer, to ensure that the ink layer in the first recessed groove 1211 does not exceed the height of the first recessed groove 1211 during ink coating.

[0040] The ink-coated lens 1 has a first recessed groove 1211 on the side of the first non-effective diameter portion 12 where the ink layer is set, so as to leave space for ink accumulation. During the ink coating process, the ink accumulates in the first recessed groove 1211, so as to ensure that the ink thickness on the side of the first non-effective diameter portion 12 is uniform and avoids tilting during assembly.

[0041] It is understandable that during ink application, both the starting and ending positions of the ink application are located within the first recessed groove 1211 to ensure that the ink accumulates within the first recessed groove 1211; and by setting the first recessed groove 1211, the ink application equipment does not require high-precision positioning control, thus reducing the difficulty of automated production operation.

[0042] Optionally, the depth of the first recessed groove 1211 is set between 0.01mm and 0.1mm; the width of the first recessed groove 1211 is set between 0.05mm and 1mm. Within this size design range, it can be ensured that the ink in the first recessed groove 1211 does not overflow.

[0043] In one embodiment, such as Figures 1-2 As shown, when the ink-coated lens 1 is a plastic part, it is a plastic lens. The depth of the first recessed groove 1211 is set between 0.01mm and 0.05mm. The plastic lens is manufactured by casting. The first recessed groove 1211 is directly formed during the casting of the plastic lens, resulting in high dimensional accuracy. The depth of the first recessed groove 1211 can be made relatively small, that is, greater than the thickness of the ink layer.

[0044] When the coated lens 1 is a plastic lens, the plastic lens has a gate position 122. In order to facilitate the later assembly and positioning of the plastic lens, the first recessed groove 1211 is distributed at 180° with the gate position 122 of the plastic lens.

[0045] In another embodiment, such as Figures 3-4 As shown, when the ink-coated lens 1 is a glass component, it is a glass lens. The depth of the first recessed groove 1211 is set between 0.03mm and 0.1mm. Since the glass lens is processed by core taking from the nitrile material, the processing error will be relatively large. It is necessary to process the depth of the first recessed groove 1211 on the glass lens to be larger, but it also needs to be controlled within 0.1mm to prevent the reflection of stray light caused by increasing the first recessed groove 1211.

[0046] In this embodiment, the thickness of the ink layer is set between 0.005mm and 0.01mm. By controlling the thickness of the ink layer within the above range, it is ensured that there is no white showing in the ink-coated area 121.

[0047] To avoid generating new stray light, the bottom surface and the wall surface of the first recessed groove 1211 are covered with ink to prevent white areas from showing.

[0048] Example 2

[0049] like Figures 5-7 As shown, this embodiment of the present invention provides a blackened lens 1, which is used to bond with an adhesive lens to form a combined lens. The combined lens includes an adhesive lens 2 and a blackened lens 1 bonded together.

[0050] The adhesive lens 2 includes a second effective diameter portion 21 and a second non-effective diameter portion 22 surrounding the second effective diameter portion 21. The second non-effective diameter portion 22 has an annular boss 221 on its side facing the ink-coated lens 1. The ink-coated lens 1 includes a first effective diameter portion 11 and a first non-effective diameter portion 12 surrounding the first effective diameter portion 11. The first non-effective diameter portion 12 has an annular groove 123 on its side facing the adhesive lens 2. When the adhesive lens 2 and the ink-coated lens 1 are bonded together, the annular boss 221 and the annular groove 123 are interlocked.

[0051] Furthermore, ink is coated inside the annular groove 123 to form an ink layer. A second recessed groove 1231 is provided on the bottom surface of the annular groove 123. The second recessed groove 1231 extends through the annular groove 123 radially along the ink-coating lens 1 to ensure that there is no ink accumulation on the bottom surface of the entire annular groove 123. Moreover, the depth of the second recessed groove 1231 is greater than the thickness of the ink layer to ensure that the ink layer in the second recessed groove 1231 does not exceed the second recessed groove 1231 during ink coating.

[0052] By creating a second recessed groove 1231 on the bottom surface of the annular groove 123 where the ink layer is provided in the first non-effective diameter portion 12 of the ink-coated lens 1, space is provided for ink accumulation. This allows ink to accumulate in the second recessed groove 1231 during the ink coating process in the annular groove 123, ensuring uniform ink thickness on the bottom surface of the annular groove 123 and preventing inadequate adhesion between the bonding lens 2 and the ink-coated lens 1.

[0053] In this embodiment, the depth of the second recessed groove 1231 is set between 0.03mm and 0.05mm; the width of the second recessed groove 1231 is set between 0.05mm and 1mm; the depth and width of the second recessed groove 1231 are set in such a way that the ink accumulated in the second recessed groove 1231 can avoid interference with the annular boss 221.

[0054] In this embodiment, the thickness of the ink layer is set between 0.005mm and 0.01mm to ensure that there is no white residue inside the annular groove 123.

[0055] In this embodiment, the bottom surface of the second recessed groove 1231 and the wall surface of the second recessed groove 1231 are both covered with ink to avoid the appearance of new stray light.

[0056] This embodiment also provides a combined lens, including an adhesive lens 2 and the above-mentioned coated lens 1.

[0057] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0058] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
