Description

Technical Field

[0001] The utility model relates to the field of lens manufacturing, in particular to an auxiliary device for lens coating. Background Art

[0002] Lens coating technology is an important part of modern optical manufacturing, which aims to enhance the performance of lenses, such as improving light transmittance, increasing wear resistance, reducing reflection, etc. In this process, the lens needs to be stably and evenly coated with one or more layers of thin film materials. However, in actual operation, due to the limitations of coating technology and equipment, the coating effect of certain parts of the lens may be difficult to achieve the expected effect.

[0003] Before coating, lenses are usually placed in special porous jigs. These jigs are designed with precise grooves to hold and position the lenses. The size and shape of the grooves are determined according to the specifications of the lens to ensure the stability and position accuracy of the lens during the coating process.

[0004] However, when the bottom portion of the lens is placed in the groove, this area may be blocked or affected during coating due to the presence of the groove, resulting in the coating material being unable to evenly cover the surface of the bottom portion of the lens. Summary of the invention

[0005] In order to solve the above problems, the utility model discloses an auxiliary device for lens coating.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions: an auxiliary device for lens coating, comprising a bottom shell and a guide plate, the top surface of the bottom shell is used to place an adhesive pad paper layer, and the adhesive pad paper layer is used to adhere the lens to be coated;

[0007] One side of the guide plate is recessed inward to form a groove, and a plurality of guide holes are evenly distributed on the inner surface of the groove. The aperture of the guide holes matches the outer diameter of the lens. When the guide plate is placed on the adhesive pad paper layer, a gap is formed between the inner surface of the groove and the adhesive pad paper layer.

[0008] In a possible implementation, the bottom shell is circular in shape, and a flange is formed on the outer circumference of the bottom shell, and the inner diameter of the groove is greater than the outer diameter of the bottom shell.

[0009] Wherein, a plurality of guide blocks are evenly distributed on the inner side of the flange, and the guide blocks have inclined guide slopes.

[0010] In addition, a retaining ring is disposed on the outer edge of the other side of the guide plate, and the guide hole is located in the area surrounded by the retaining ring.

[0011] Furthermore, the auxiliary device also includes a pressure plate, which is circular in shape, and the outer diameter of the pressure plate is smaller than the inner diameter of the retaining ring, and the surface of the pressure plate can cover the entire area where the guide hole is located.

[0012] The outer side surface of each guide hole is provided with a chamfer.

[0013] The auxiliary device in the embodiment of the utility model can firstly realize accurate positioning and placement of the lens by combining the bottom shell with the guide plate. The top surface of the bottom shell is used to place the adhesive pad paper layer to facilitate the fixing of the lens, and the guide holes evenly distributed on the guide plate match the outer diameter of the lens, which can ensure the stability and accuracy of the lens during placement.

[0014] Secondly, the gap between the guide plate and the adhesive pad paper layer can effectively prevent the two from sticking together, ensuring smooth and efficient operation. This design not only simplifies the operation process, but also reduces the risk of lens damage or position displacement caused by adhesion;

[0015] In addition, the use of this auxiliary device can also improve the efficiency and quality of coating. By accurately placing the lenses, the spacing between the lenses can be avoided to be too small or too large, thereby ensuring the uniformity and consistency of the coating process. At the same time, since the adhesive padding paper layer only acts on the bottom surface of the lens and does not block the side of the lens, the coating effect is more ideal.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0021] 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.

[0022] 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.

[0023] Example 1: Figure 1-4 As shown, an auxiliary device for lens coating comprises a bottom shell 100 and a guide plate 200, wherein the top surface of the bottom shell 100 is used for placing an adhesive pad paper layer, and the adhesive pad paper layer is used for bonding the lens to be coated;

[0024] In a possible implementation, the adhesive pad paper layer is made of heat-resistant high-temperature adhesive tape, and is generally circular in shape, capable of withstanding the high temperature environment during the coating process, while maintaining viscosity and effectively bonding the lens to be coated. The bottom shell 100 is a circular plate-shaped structure adapted thereto.

[0025] In order to facilitate the positioning of the adhesive pad paper layer placed on the bottom shell 100 and prevent it from being separated from the bottom shell 100, a flange 101 is formed on the outer periphery of the bottom shell 100, and at the same time, the inner diameter of the groove 201 is larger than the outer diameter of the bottom shell 100, so that the guide plate 200 can be inserted into the outer side of the bottom shell 100. The inner diameter of the groove 201 is slightly larger than the outer diameter of the bottom shell 100, so that the guide plate 200 can be easily inserted into the outer periphery of the bottom shell 100. A plurality of guide holes 202 are evenly distributed on the inner surface of the groove 201, and the apertures of these guide holes 202 match the outer diameter of the lens to be coated, and are used to guide and position the placement of the lens.

[0026] In order to prevent the two from sticking together when the guide plate 200 is placed outside the adhesive pad paper layer, one side of the guide plate 200 is recessed inward to form a groove 201, and the inner surface of the groove 201 is evenly distributed with multiple guide holes 202, and the aperture of the guide holes 202 matches the outer diameter of the lens. When the guide plate 200 is placed on the adhesive pad paper layer, a gap is formed between the inner surface of the groove 201 and the adhesive pad paper layer. In order to maintain a good guiding effect while avoiding contact between the adhesive pad paper layer and the guide plate 200, the width of the gap is preferably 1-2 mm.

[0027] When performing the coating operation, first place a layer of adhesive padding paper on the inner side of the flange 101 of the bottom shell 100, then insert the guide plate 200 into the outer periphery of the bottom shell 100, and at this time, the guide hole 202 on the guide plate 200 faces the adhesive padding paper layer, and the lens to be coated is pressed and bonded to the adhesive padding paper layer through the guide hole 202 on the guide plate 200, and is bonded and fixed. Since the guide holes 202 on the guide plate 200 are evenly spaced, the lenses placed through the guide plate 200 can maintain a fixed distance, thereby leaving a gap to avoid the distance between the two being too small, which affects the coating. In addition, since the adhesive padding paper layer is used to bond and fix the lens, it acts on the bottom surface of the lens. Compared with the traditional fixture placement hole to fix the lens, it will not block the side of the lens, and the coating effect is better.

[0028] There are multiple guide blocks 111 evenly distributed on the inner side of the flange 101, and the guide blocks 111 have inclined guide slopes 112. The guide slopes 112 on the guide blocks 111 can provide certain guidance when placing the adhesive pad paper layer, making the operation more convenient and accurate.

[0029] In addition, a circle of retaining ring 203 is provided on the outer edge of the other side of the guide plate 200, and the guide hole 202 is located in the area surrounded by the retaining ring 203. During operation, multiple lenses to be bonded and fixed can be placed on the surface of the guide plate 200 at the same time, and then the lenses are placed one by one on the adhesive pad paper layer through the guide hole 202. When multiple lenses are placed on the surface of the guide plate 200, it can play a certain limiting role.

[0030] The outer side surface of each guide hole 202 is provided with a chamfer, which can play a certain guiding role when the lens is installed in the guide hole 202.

[0031] Example 2: See Figure 1On the basis of Example 1, a pressing plate 300 is added. The pressing plate is circular in shape, and the outer diameter of the pressing plate 300 is smaller than the inner diameter of the retaining ring 203. At the same time, the surface of the pressing plate 300 can cover the entire area where the guide hole 202 is located, and is used to further press the lens placed on the adhesive pad paper layer through the guide hole 202. The specific thickness of the lens is greater than the thickness of the guide plate 200. After the lens is placed, the outer end of the lens extends to the outer end of the guide hole 202, and multiple lenses can be simultaneously pressed and fixed on the adhesive pad paper layer through the pressing plate 300.

[0032] 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.
