Description

Technical Field

[0001] This utility model belongs to the technical field of optical lens processing equipment, and in particular relates to an optical lens cutting device. Background Technology

[0002] In the optical lens manufacturing process, lens cutting is one of the key steps, requiring the lens to be stably fixed to ensure cutting precision. Traditional optical lens cutting equipment often uses vacuum adsorption to fix the lens, but existing adsorption devices have limited adsorption area, resulting in unstable lens fixation and easy displacement during cutting, affecting processing quality. Secondly, uneven distribution of adsorption force can easily cause local stress concentration on the lens, even leading to lens breakage. In addition, some adsorption devices use hard materials, which can easily damage the lens surface, especially for high-precision optical lenses, where surface scratches will reduce product yield.

[0003] Therefore, there is an urgent need for an optical lens cutting device that can provide wide-area, uniform adsorption force while protecting the lens surface and has a simple structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an optical lens cutting device, whose suction device can generate a wide-area adsorption force through the airflow dispersion block, stably fix the lens, and avoid damage to the lens surface.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes an adsorption device for adsorbing and fixing lenses. The adsorption device includes a circular tube, a shell, and an airflow dispersion block. The airflow dispersion block is embedded in the inner side of the shell to disperse the airflow and expand the adsorption area. The circular tube is connected to the air extraction device on an external lens cutting device.

[0006] Furthermore, when the air extraction device draws in air, it generates negative pressure. The airflow is dispersed by the airflow dispersion block and then converges into the circular tube, thereby generating a wide-area adsorption force on the top surface of the airflow dispersion block.

[0007] Furthermore, a circular groove is provided on the inner side of the housing, the airflow dispersion block is placed in the circular groove, and a pipe is fixedly provided at the bottom of the housing to connect the circular groove and the circular pipe installed in the pipe.

[0008] Furthermore, a limiting ring with an annular protrusion is fixedly provided on the inner annular wall surface of the housing, and the limiting ring is interference-engaged with the outer surface of the airflow dispersion block.

[0009] Furthermore, the limiting ring locks the airflow dispersion block to prevent it from shifting.

[0010] Furthermore, the bottom surface of the housing is provided with a sunken disc-shaped air chamber, which is connected to the air hole at the bottom of the housing through an arc-shaped air passage, and the airflow dispersion block is in contact with the outer periphery of the housing surface of the disc-shaped air chamber.

[0011] Furthermore, the sunken disc-shaped air chamber maintains a distance from the bottom surface of the airflow dispersion block to form a space for airflow convergence, which facilitates the convergence and converging of airflow and prevents the dispersed airflow from being unable to flow out from the air holes at the bottom of the shell.

[0012] Furthermore, the airflow dispersion block is breathable heat-pressed cotton.

[0013] Furthermore, the numerous internal pores of the breathable heat-pressed cotton facilitate airflow dispersion and circulation, while its flexible texture prevents damage to the lenses.

[0014] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the airflow is dispersed by the airflow dispersion block, so that the adsorption force is evenly distributed on the top surface of the airflow dispersion block, thereby achieving wide-area adsorption of the lens, fixing it firmly, and improving the cutting accuracy. 2. In this utility model, the limiting ring and the airflow dispersion block are interference-engaged to prevent the airflow dispersion block from shifting during operation and to ensure adsorption stability; 3. In this utility model, the design of the disc-shaped air chamber and the arc-shaped air channel enables the dispersed airflow to smoothly converge and flow out, reducing airflow resistance and improving adsorption efficiency; 4. In this utility model, the airflow dispersion block is made of breathable hot-pressed cotton, which is soft and porous, ensuring smooth airflow while avoiding scratches on the lens surface.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Combination Figures 1 to 3 An optical lens cutting device is shown, including a suction device for adsorbing and fixing lenses. The suction device includes a circular tube 1, a housing 2, and an airflow dispersion block 3. The airflow dispersion block 3 is embedded in the inner side of the housing 2 to disperse the airflow and expand the adsorption area. The circular tube 1 is connected to the air extraction device on the external lens cutting device.

[0019] When the air extraction device draws in air, it generates negative pressure. The airflow is dispersed by the airflow dispersion block 3 and then converges into the circular tube 1, thereby generating a wide-area adsorption force on the top surface of the airflow dispersion block 3.

[0020] The inner side of the housing 2 is provided with a circular groove 21, the airflow dispersion block 3 is placed in the circular groove 21, and the bottom of the housing 2 is fixedly provided with a pipe fitting 22 for connecting the circular groove 21 and the circular pipe 1 installed in the pipe fitting 22.

[0021] A limiting ring 23 with an annular protrusion is fixedly provided on the inner annular wall surface of the housing 2, and the limiting ring 23 is interference-engaged with the outer surface of the airflow dispersion block 3.

[0022] The limiting ring 23 holds the airflow dispersion block 3 in place to prevent it from shifting.

[0023] The bottom surface of the inner shell 2 is provided with a sunken disc-shaped air chamber 24. The disc-shaped air chamber 24 is connected to the air hole at the bottom of the shell 2 through an arc-shaped air passage 25. The airflow dispersion block 3 is in contact with the outer periphery of the shell 2 of the disc-shaped air chamber 24.

[0024] The sunken disc-shaped air chamber 24 maintains a distance from the bottom surface of the airflow dispersion block 3 to form a space for airflow convergence, which facilitates the convergence and converging of airflow and prevents the dispersed airflow from being difficult to flow out from the air hole at the bottom of the shell 2.

[0025] The airflow dispersion block 3 is made of breathable heat-pressed cotton.

[0026] The breathable heat-pressed cotton has a large number of internal pores, which facilitates airflow dispersion and circulation, while its flexible texture can prevent damage to the lenses.

[0027] Working principle: During use, when the external air extraction device is activated, air is drawn in through the circular tube 1, creating negative pressure inside the suction device. The lens is placed on the top surface of the airflow dispersion block 3, and airflow is drawn in through the gap between the lens and the airflow dispersion block 3, passing through the micropores of the airflow dispersion block 3. Due to the dispersing effect of the airflow dispersion block 3, the single airflow is decomposed into multiple fine streams, which pass evenly through the airflow dispersion block 3, thereby forming a widely distributed adsorption force on the top surface of the airflow dispersion block 3, firmly fixing the lens. The dispersed airflow converges within the disc-shaped air chamber 24, then flows through the arc-shaped air passage 25 to the pipe 22, and finally exits through the circular pipe 1. The design of the disc-shaped air chamber 24 avoids the airflow directly impacting the bottom of the shell, allowing the airflow to converge smoothly and reducing energy loss; the arc-shaped air passage 25 further optimizes the airflow path, ensuring smooth airflow out. The limiting ring 23 fixes the airflow dispersion block 3 by interference fit, preventing it from shifting under the action of airflow. The softness of the airflow dispersion block 3 buffers the pressure during adsorption and protects the lens surface from damage.
