Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to an auxiliary device for pressing a polishing sheet onto an aluminum mold for polishing optical lenses. Background Technology

[0002] In the field of optical lens manufacturing, especially in the machining of CR-39 resin lenses, polishing is a crucial step in achieving lens transparency and high gloss. During polishing, adhesive-coated polishing pads must be adhered to the surface of the aluminum mold to ensure the desired polishing effect. However, current technology primarily relies on manual operation, i.e., manually attaching the polishing pads to the aluminum mold and pressing them down. This traditional method has significant drawbacks:

[0003] Insufficient adhesion: Manual pressing cannot guarantee uniform pressure distribution, resulting in air bubbles or gaps on the contact surface between the polishing pad and the aluminum mold, low adhesion density, easy displacement during polishing, and serious impact on polishing quality.

[0004] Uncontrollable pressing time: Manual operation makes it difficult to precisely control the pressing time, and the adhesive curing process is unstable, which further increases the risk of adhesive failure;

[0005] Poor quality consistency: Manual operation is greatly affected by subjective factors, making it impossible to standardize the pressure application process, resulting in product quality fluctuations and increasing the difficulty of quality control;

[0006] Waste of consumables and high costs: Insecure bonding requires frequent replacement of polishing pads, resulting in waste of consumables and increased production costs.

[0007] Therefore, there is an urgent need for an auxiliary device that can apply pressure evenly, precisely control the pressing time, and effectively eliminate interface bubbles, in order to overcome the shortcomings of manual operation in the existing technology and improve the quality of polishing sheet pressing and production efficiency.

[0018] Further improvements include covering the side of the buffer sponge that contacts the polishing sheet with a flexible silicone layer.

[0019] Further improvements include the installation of a control panel on the housing, and the control panel being electrically connected to the cylinder and air source control system.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0027] refer to Figure 1 , Figure 2 and Figure 3 An auxiliary device for pressing a polishing sheet onto an aluminum mold for polishing optical lenses includes a housing 8, the interior of which is constructed as a hollow structure and one side of which is an open structure, so as to facilitate the placement and removal of the polishing aluminum mold by the operator.

[0028] Cylinder 1 is positioned above housing 8, and its output end is connected to positioning block 3 located inside housing 8, thereby controlling the positioning block 3 to move up and down.

[0029] The air supply control system is installed inside the housing 8 and is connected to the cylinder 1 through a pipeline. It is used to supply air to the cylinder 1.

[0030] The time relay 6 is integrated into the air source control system. By adjusting its parameters, the continuous pressure application time of the cylinder 1 is controlled to ensure that the adhesive is fully cured.

[0031] The housing 8 contains a buffer hard sponge 4 located directly below the positioning block 3. The buffer hard sponge 4 is made of high-density polyurethane material with a thickness of 20mm and an elastic modulus of 0.5-1.0MPa. It can deform uniformly under pressure, converting the impact force into elastic potential energy. This protects the surface of the polishing pad from damage while also eliminating interface bubbles, thereby improving the stability of subsequent polishing processes.

[0032] In this embodiment, the positioning block 3 is made of aluminum alloy. The aluminum alloy material reduces the overall weight of the tooling, and the good corrosion resistance of the aluminum alloy material can effectively adapt to complex testing environments such as high and low temperatures and high humidity.

[0033] In this embodiment, a groove matching the aluminum mold is provided on the lower surface of the positioning block 3, thereby fixing the position of the aluminum mold.

[0034] In this embodiment, anti-slip texture is provided on the inner wall of the groove of the positioning block 3, which can further enhance the stability of the aluminum mold.

[0035] In this embodiment, the air source control system includes an air source triplet 7 and an air source button 5 for controlling the opening and closing of the air source triplet 7. The air source button 5 is electrically connected to the air source triplet 7 and is located outside the housing 8. The air source triplet 7 includes a filter, a pressure reducing valve, and an oil mist lubricator. It is connected to the cylinder 1 through a pipeline. The filter purifies the air source to avoid jamming and wear caused by impurities; the pressure reducing valve stabilizes the pressure to ensure the accuracy of component operation (such as stable cylinder thrust); and the oil mist lubricator provides continuous lubrication to reduce friction loss.

[0036] In this embodiment, a flexible silicone layer is provided on the side of the buffer hard sponge 4 that contacts the polishing sheet. The thickness of the flexible silicone layer is preferably 2mm to further prevent scratches on the surface of the polishing sheet.

[0037] In this embodiment, a control panel 2 is provided on the housing 8, and the control panel 2 is electrically connected to the cylinder 1 and the air source control system.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
