[0002] The light-shielding sheet, also known as a light-blocking sheet, is an essential light-shielding component in fields such as cameras and mobile phone cameras. Its purpose is to prevent stray light from entering the viewfinder and affecting the imaging quality. After the existing light-shielding sheet is formed, a carbon ink layer is coated on the end face of the light-shielding sheet. Although the carbon ink layer can relatively reduce the reflectivity of the light-shielding sheet and enhance the anti-glare function of the light-shielding sheet, it still cannot meet the requirements of existing users for imaging. Moreover, in an outdoor environment with sufficient sunlight, the glare phenomenon is still obvious and the temperature resistance is poor. In view of this, the inventor has made a new invention.

A first anti-glare film layer is arranged on the first end face, and a second anti-glare film layer is arranged on the second end face.

[0005] Preferably, both the first anti-glare film layer and the second anti-glare film layer are plasma sputtering coating layers.

[0006] Preferably, the first anti-glare film layer is a titanium film layer; the second anti-glare film layer is a silicon dioxide film layer.

[0007] Preferably, the light-transmitting hole is inclined from the first end face to the center line and is distributed in an inverted conical shape.

[0008] Preferably, it further includes a protective snap ring for protecting the light-shielding sheet. A plurality of clamping platforms are arranged at the bottom end of the protective snap ring. The clamping platforms and the protective snap ring enclose to form a clamping position for accommodating the light-shielding sheet body.

[0009] Preferably, a plurality of arc-shaped grooves for facilitating the loading and unloading of the light-shielding sheet are arranged at the upper end of the protective snap ring.

[0010] Preferably, the light-shielding sheet body is formed by a PP or PET material.

[0015] Light-shielding sheet body - 1, light-transmitting hole - 11, first end face - 12, second end face - 13, first anti-glare film layer - 14, second anti-glare film layer - 15, protective snap ring - 2, snap table - 21, snap position - 22, arc-shaped groove - 23. Detailed Description of the Invention

[0016] The following will Figures 1 to 2 be described in detail with reference to the accompanying drawings.

[0017] The present utility model is an anti-glare light-shielding sheet, which is mainly used in the camera of electronic products. The present utility model includes a light-shielding sheet body 1, and the light-shielding sheet body 1 is injection-molded with a plastic material; a light-transmitting hole 11 is opened in the middle of the light-shielding sheet body 1, and the light-shielding sheet body 1 is provided with at least an opposite first end face 12 and a second end face 13, and the light-transmitting hole 11 extends from the first end face 12 to the second end face 13; the first end face 12 is provided with a first anti-glare film layer 14, and the second end face 13 is provided with a second anti-glare film layer 15. Compared with the traditional light-shielding sheet, the present utility model is provided with a first anti-glare layer and a second anti-glare layer on two end faces of the light-shielding sheet respectively, further reducing the reflectivity of the light-shielding sheet, so that the light-shielding sheet has a good anti-glare effect and optimizes the imaging effect to meet

[0018] Preferably, both the first anti-glare film layer 14 and the second anti-glare film layer 15 are processed and formed by means of plasma sputtering coating. Among them, the first anti-glare film layer 14 is a titanium film layer; the second anti-glare film layer 15 is a silicon dioxide film layer. The film layer formed by plasma sputtering coating has better density and hardness, so that the reflectivity of the coated light-shielding sheet material is lower and the anti-glare effect is better. On the other hand, since plasma sputtering coating deposits materials in a molecular manner and the coating thickness is relatively thin, it will not damage the surface shape accuracy of the parts, and the comprehensive properties such as anti-reflection, hardening, and anti-fouling of the light-shielding sheet material after coating are improved.

[0019] Preferably, as Figure 2 shown, the light-transmitting holes 11 are inclined from the first end face 12 towards the center line and are distributed in an inverted conical shape. The light-transmitting holes 11 arranged in a trumpet shape can further enhance the reflection performance of the light-shielding sheet, reduce the entry of stray light, and improve the imaging quality.

[0020] To further improve the technical solution, the present utility model further includes a protective snap ring 2. The protective snap ring 2 is sleeved outside the light-shielding sheet body 1 to protect the light-shielding sheet body 1 and extend the service life of the light-shielding sheet; secondly, the protective snap ring 2 can support the light-shielding sheet and further enhance the strength of the light-shielding sheet.

[0021] As an embodiment, a plurality of clamping platforms 21 are provided at the bottom end of the protective snap ring 2. The clamping platforms 21 and the protective snap ring 2 enclose to form a clamping position 22 for accommodating the light-shielding sheet body 1. During use, the light-shielding sheet body 1 is snapped into the clamping position 22 to form a tight fit with the protective snap ring 2.

[0022] Preferably, as Figure 1 shown, a plurality of arc-shaped grooves 23 are provided at the upper end of the protective snap ring 2. The arc-shaped grooves 23 assist in exposing the edge of the light-shielding sheet body 1. When it is necessary to disassemble the light-shielding sheet body 1, the arc-shaped grooves 23 can be used to pry the light-shielding sheet body 1 to quickly disassemble the light-shielding sheet body 1 from the protective snap ring 2.

[0023] As an embodiment, both the light-shielding sheet body 1 and the protective snap ring 2 are formed of PP or PET materials. The PP or PET materials have a low cost, can effectively reduce the manufacturing cost of the light-shielding sheet, and the PP or PET materials have good strength, high-temperature resistance, etc., and the manufactured light-shielding sheet has better performance and a wider application range.

[0024] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
