Description

Technical Field

[0001] The utility model relates to the field of lens manufacturing, in particular to a lens edge grinding processing component. Background Art

[0002] In the optical manufacturing and eyewear industry, lens edging is a critical step because it can significantly improve the clarity and optical performance of the lens. To complete this process step, the industry generally uses an edging system consisting of a grinding wheel and a clamping assembly. The grinding wheel, as the main tool in the edging process, is usually made of fine abrasives and rotates at high speed to remove tiny defects on the lens surface, thereby achieving a smooth and bright effect.

[0003] The components used for lens edge grinding usually include a grinding wheel and a clamping component aligned with the grinding wheel. The clamping component includes two oppositely arranged chucks, and oppositely arranged pressure rods are arranged on the inner sides of the two chucks. During operation, the lens is placed between the two pressure rods, and the pressure rods are driven by the chucks to approach each other to support the lens, and the lens is edged by the grinding wheel.

[0004] However, after the edging process is completed, the two chucks need to be separated from each other to remove the lens. If the operation is not done properly, the lens may fall off easily, thereby causing damage to it. Summary of the invention

[0005] In order to solve the above problems, the utility model discloses a lens edge grinding component.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions: a lens edge grinding processing component, comprising a grinding wheel and a clamping component aligned with the grinding wheel, the clamping component comprising two clamps arranged opposite to each other, the inner sides of the two clamps are provided with oppositely arranged pressure rods, one of the two clamps is provided with two support sleeves arranged in parallel and spaced relation, the other is provided with a support rod arranged in parallel and spaced relation corresponding to the support sleeves, the outer end of the support rod is slidably inserted into the support sleeve, and the support sleeve is located below the pressure rod;

[0007] The distance between the two supporting sleeves is smaller than the diameter of the lens to be processed.

[0008] In the above solution, a circle of grooves is formed on the circumference of the grinding wheel, thereby forming steps on both sides of the grinding wheel for edge grinding of lenses.

[0009] In the above solution, a plurality of chip notches are provided on the circumference of the step, and the chip notches are arranged close to the groove.

[0010] In the above solution, the inner side of the chip notch passes through the groove and is connected to the groove.

[0011] In the above solution, the edge of the chip accommodating notch has a guide surface inclined inwardly.

[0012] In the above solution, the surface of the support sleeve is coated with a rubber buffer layer.

[0013] The components in the embodiment of the utility model include a grinding wheel and a clamping component that matches the grinding wheel. The clamping component includes two relatively arranged chucks, and the inner sides of the two chucks are provided with relatively arranged pressure rods. One of the two chucks is provided with two parallel and spaced support sleeves, and the other one is provided with support rods that are parallel and spaced corresponding to the support sleeves. The support sleeves and the support rods are used in coordination, so that when the chucks 200 are approaching or separating from each other, there is always a support mechanism located under the lens to provide stable support. This design not only avoids the risk of the lens falling from a high place after the edge grinding operation is completed, but also ensures the safety of the lens during the entire operation process.

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0019] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0020] Example 1: Figure 1-2 As shown, a lens edge grinding component includes a grinding wheel 100 and a clamping component aligned with the grinding wheel 100, the clamping component includes two chucks 200 arranged opposite to each other, the grinding wheel 100 is installed in a grinding device, the chuck 200 is specifically a device for clamping a lens in the grinding device, and the driving components of the grinding wheel 100 and the chuck 200 are both existing structures;

[0021] The inner sides of the two chucks 200 are both provided with opposing pressure rods 201, one of the two chucks 200 is provided with two support sleeves 202 arranged in parallel and spaced apart, and the other one is provided with a support rod 203 arranged in parallel and spaced apart corresponding to the support sleeves 202, the outer end of the support rod 203 is slidably inserted into the support sleeve 202, and the support sleeve 202 is located below the pressure rod 201, that is, the support sleeve 202 and the support rod 203 are always located on the lower side of the pressure rod 201 for clamping the lens; and the outer end of the support sleeve 202 is arranged close to the other chuck 200, and the distance between the two support sleeves 202 is smaller than the diameter of the lens to be processed.

[0022] That is, a pressing rod 201 is provided on the inner side of each chuck 200. When the two chucks 200 are close to each other, the pressing rods 201 will work together to clamp the lens firmly in the edge grinding position. In order to ensure the safety of the lens during the edge grinding process, especially to prevent the lens from falling from a high place when the chucks 200 are separated, a set of supporting mechanisms is designed in this embodiment.

[0023] During the edge grinding operation, the lens to be edged is placed between the two chucks 200, and then the edge grinding equipment is started, and the pressing rods 201 on the two chucks 200 are moved closer to each other to clamp the lens to be processed; after the edge grinding operation is completed, the two chucks 200 are separated from each other, and the support rod 203 located at the lower side of the lens partially extends from the support sleeve 202, but the end is still located in the support sleeve 202, so the support sleeve 202 and the support rod 203 are always located at the lower side of the lens regardless of whether the two chucks 200 are approaching or separating from each other, and can support the lens after it falls, so as to prevent it from falling from a high place and causing damage. In this process, although the support sleeve 202 and the support rod 203 are located below the lens, they are not in direct contact with it, so they will not affect the edge grinding operation.

[0024] In order to further improve the protection effect of the lens, this embodiment also covers a rubber buffer layer (not shown in the figure) on the surface of the support sleeve 202. When the lens contacts the support mechanism, it plays a buffering role, further reducing the risk of damage to the lens.

[0025] Example 2: See Figure 2-3 The grinding wheel 100 is formed with a circle of grooves 101 on its circumference, thereby forming steps 102 for edge grinding of lenses on both sides of the grinding wheel 100. When grinding the lens, the grooves 101 can avoid the non-grinding area in the middle of the lens, such as a lens with a concave surface in the middle. The grinding wheel 100 can also act more accurately on the area of ​​the lens that needs to be ground during the edge grinding process, thereby improving the efficiency and effect of the edge grinding process.

[0026] In order to reduce the accumulation of debris generated by grinding in the grinding area during the grinding process, a plurality of chip notches 121 are opened in the circumferential direction of the step 102, and the chip notches 121 are arranged close to the groove 101 to accommodate part of the debris generated during the grinding process.

[0027] The inner side of the chip notch 121 passes through the groove 101 and is connected to the groove 101 , so that the debris in the chip notch 121 can be partially discharged to the groove 101 and then fall out of the groove 101 .

[0028] The edge of the chip notch 121 has a guide surface 122 inclined inwardly, which can guide the generated debris and make it fall into the chip notch 121 more smoothly, thereby further improving the cleaning efficiency of the debris.

[0029] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
