Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, and in particular to the structure of a multifunctional gradient lens processing fixture. Background Technology

[0002] Gradient lenses, an innovative product in the eyewear industry, are currently a very popular type of eyewear on the market. Also known as gradient lenses, they are lenses with a color-changing effect. The color of a gradient lens gradually fades from the top to the bottom of the lens, automatically adjusting its color under different lighting conditions to enhance its aesthetic appeal. Gradient lenses can reduce lens reflection, prevent glare, and improve visual perception. They can also increase lens transparency, allowing people to see things more clearly. Therefore, gradient lenses offer many advantages in terms of eye protection, improved visual effects, and aesthetics, making them an excellent choice, especially for those who prioritize eye health and a stylish appearance.

[0003] The principle behind gradient lenses is the use of advanced technology with multiple special coatings. The coating thickness gradually changes from top to bottom, allowing the top and bottom of the lens to reflect different wavelengths of light. The gradual transition between the top and bottom creates a constantly changing yet consistent color depth suitable for the eye, thus protecting the eyes and improving visual acuity. In current technology, gradient lenses are manufactured by fixing the lens in a special fixture, with the lens surface forming a specific angle with the direction of the coating evaporation source. Because the distance between the lens and the evaporation source varies at different positions, the coating thickness varies, resulting in a gradual color change. However, existing fixtures can only process one type of gradient lens (with a fixed degree of color gradation) per specification. To produce other types of gradient lenses, corresponding fixtures are required, leading to high processing costs, the need to change fixtures according to orders, and the limitation that only one type of gradient lens can be produced per batch, resulting in waste if orders are small.

[0004] In view of this, the inventor, relying on his professional technical level and rich experience in long-term research, design and manufacturing, as well as his familiarity with the structure of eyeglasses, has developed a new type of multifunctional progressive lens processing fixture through repeated design, experimentation, modification and testing, and this invention is thus born. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional gradient lens processing fixture, which has a simple and lightweight structure, firmly and stably clamps the lens, and can quickly adjust the lens clamping angle. It is suitable for processing and producing various types of gradient lenses.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A multifunctional gradient lens processing fixture has a base for installation in a coating equipment and two side supports for clamping and fixing the lens. The lower ends of the two side supports are connected to the left and right sides of the base, and the upper ends of the two side supports extend upwards to the left and right sides. The two side supports form a number of locking points on their opposite surfaces, and the locking points of the two side supports form a positioning space for clamping the lens.

[0008] The two side brackets each form two rows of side locking points on the front and rear sides, and each form a pair of top locking points on the top. By selecting different side locking points and top locking points to cooperate or different side locking points to cooperate, a variety of positioning spaces for clamping lenses can be provided.

[0009] The two side supports also have notches at the top, which not only saves materials but also provides sufficient elasticity when clamping the lens, so that the clamping force is just right and the clamping stability and firmness are guaranteed.

[0010] The base is a square sheet, and the two side supports are two strip sheets. This design is simple, sturdy, and saves materials. It also facilitates the installation of fixtures and the clamping and positioning of lenses.

[0011] The base and two side supports are integrally bent from sheet material, making the entire fixture structure simple, easy to process, and improving manufacturing efficiency.

[0012] The two side supports are symmetrically arranged, making the fixture installation easier and eliminating the need to consider the installation direction.

[0013] The base and the two side supports form an isosceles trapezoidal design, which simplifies the structure.

[0014] The fixture is equipped with a rotating cylinder and a turntable. The two ends of the rotating cylinder are mounted on two turntables. Several bases are arranged axially and fixed on the surface of the rotating cylinder. The two side supports on the left and right sides of the bases extend outward from the rotating cylinder.

[0015] With the above solution, the present invention has a simple and lightweight structure. In use, it is installed in the coating equipment with the help of the base. The lens is adjusted at an angle according to the design of the gradual change of the coating and is mounted on the corresponding locking points of the two side supports so that the lens is clamped and positioned with a fixed tilt angle. Then the coating operation is carried out. Because the tilted lens surface forms a certain angle with the spray direction of the coating evaporation source, the distance between different positions of the lens and the evaporation source is different, resulting in different coating thicknesses, thus forming a gradually changing color.

[0016] Compared with the prior art, this utility model has several locking points formed on the opposite surfaces of the two side supports, and the locking points of the two side supports form a positioning space for clamping the lens. Therefore, one fixture can form multiple positioning spaces for processing and producing various types of gradient lenses. Unlike the prior art, it is not necessary to make various specifications of fixtures or to constantly change fixtures according to orders. The processing cost is greatly reduced. Moreover, the lens angle can be quickly adjusted as needed to meet product requirements during the same batch of production, so that multiple types of gradient lenses can be produced in the same batch. The production volume is determined by actual demand. Even if the order quantity is small, it can be produced together with other models, saving coating materials, eliminating waste, and improving production efficiency.

[0017] This invention is particularly suitable for gradient color coating of sunglasses, and can achieve rapid adjustment of the coating.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] The embodiments of this utility model will be fully described below with reference to the accompanying drawings. It should be noted that this utility model can be implemented in different forms, and the specific embodiments described herein are merely illustrative of the relevant structures and are not intended to limit the scope of the invention. These embodiments are provided to provide a thorough and complete disclosure of the utility model and to fully convey its scope to those skilled in the art. Furthermore, the embodiments and features described herein can be combined with each other without conflict. For ease of description, only the parts relevant to the inventive innovation are shown in the accompanying drawings.

[0027] In the description of this application, it should be understood that the terms "front," "rear," "left," "right," "upper," "lower," "inner," "outer," "first," and "second," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Any reference signs in the claims should not be interpreted as limiting the scope. The embodiments described above are only for illustrating the technical ideas and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly, but do not limit the patent scope of this utility model. All equivalent changes or modifications made in accordance with the spirit disclosed in this utility model should still be covered within the patent scope of this utility model.

[0028] like Figures 1 to 5 As shown, this utility model discloses a multifunctional gradient lens processing fixture, comprising a base 1 and two side supports 2. The base 1 is used for mounting in a coating equipment, allowing the entire fixture to be installed and fixed. The two side supports 2 are used to clamp and fix the lens 3, allowing the lens 3 to be installed in the coating equipment. The lower ends of the two side supports 2 are connected to the left and right sides of the base 1, and the upper ends of the two side supports 2 extend upwards at an angle towards the left and right sides. Several locking points 21 are formed on the opposite surfaces of the two side supports 2, and the locking points 21 of the two side supports 2 constitute a positioning space for clamping the lens 3.

[0029] When this utility model is used, it is installed in the coating equipment with the help of the base 1. The lens 3 can be adjusted to the installation and positioning angle according to the design of the gradual change of the coating, and is mounted on the corresponding locking points 21 of the two side supports 2, so that the lens 3 is clamped and positioned and the tilt angle is fixed. Then the coating operation is carried out. Because the distance between different positions on the tilted surface of the lens 3 and the evaporation source 4 in the coating equipment is different, the coating thickness is different, thus forming a gradually changing color.

[0030] This utility model further optimizes the design. The two side brackets 2 each form two rows of side locking points 211 on the front and rear sides, and each form a pair of top locking points 212 on the top. By selecting different side locking points 211 and top locking points 212 to cooperate, or different side locking points 211 to cooperate with each other, a variety of positioning spaces for clamping the lens 3 can be provided. The two rows of side locking points 211 and the pair of top locking points 212 make the clamping and positioning more stable.

[0031] This utility model further optimizes the design. The two side supports 2 also form notches 22 at the top, which not only saves materials, but also provides sufficient elasticity when clamping the lens 3, so that the clamping force of the lens 3 is just right, and ensures the stability and firmness of the clamping.

[0032] This utility model further optimizes the design. The base 1 is a square sheet, and the two side supports 2 are two rectangular sheets. This design is simple, sturdy, and material-saving, facilitating fixture installation and the clamping and positioning of the lens 3. Furthermore, the base 1 and the two side supports 2 can be integrally bent from the sheet, making the entire fixture structure simple, easy to process, and improving manufacturing efficiency. The two side supports 2 can also be symmetrically arranged, making fixture installation easier and eliminating the need to consider the installation direction. Moreover, the base 1 and the two side supports 2 of this utility model form an isosceles trapezoidal design, further simplifying the structure.

[0033] This utility model is further optimized in design. The fixture is also equipped with a rotating cylinder 5 and a turntable 6. The two ends of the rotating cylinder 5 are mounted on two turntables 6. Multiple rotating cylinders 5 can be mounted between the two turntables 6. Several bases 1 are arranged axially and fixed on the surface of the rotating cylinder 5. The two side supports 2 on the left and right sides of the base 1 extend outward from the rotating cylinder 5. During the coating process, the evaporation source 4 in the coating equipment can remain stationary. The rotation of the turntable 6 drives the rotating cylinder 5 to rotate. At the same time, the rotating cylinder 5 can also rotate on its own axis, so that the lens 3 rotates together with the rotating cylinder 5 and the turntable 6 to complete the coating operation.

[0034] This invention is particularly suitable for gradient tint coating of sunglasses, enabling rapid adjustment of the coating. The advantages of this invention are that the locking points 21 of the two side supports 2 can form multiple positioning spaces for clamping lenses 3, allowing for the production of various models of gradient tint lenses. Unlike existing technologies, it eliminates the need to manufacture various specifications of clamps and constantly change clamps according to orders, significantly reducing processing costs. Furthermore, during the same batch production, the angle of the lens 3 can be quickly adjusted as needed to meet product requirements, allowing for the production of multiple models of gradient tint lenses in the same batch. Production volume is determined by actual demand; even small orders can be produced together with other models, saving coating materials, eliminating waste, and improving production efficiency.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this application, fall within the protection scope of this application.
