Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical glass manufacturing, and in particular to a coating device for optical glass manufacturing. Background Technology
[0002] Optical glass includes colorless optical glass, colored optical glass, radiation-resistant optical glass, radiation-proof glass, and optical quartz glass. Optical glass is the foundation and an important component of the optoelectronic technology industry. In actual use, on the one hand, in order to reduce the wear and tear on the glass lenses caused by use, and on the other hand, for special use requirements, it is generally necessary to coat the surface of optical glass.
[0003] For example, the utility model disclosed in CN222250487U discloses a coating device for manufacturing optical glass, including a coating box. The coating box contains a tooling assembly, which includes a tooling table. A placement groove is provided on the top surface of the tooling table. Several silicone suction cups are arranged on the bottom surface of the placement groove, and optical glass is placed on the top of the suction cups. A top cover is provided on the top surface of the tooling table and around the placement groove. A water collection groove is provided on the inner circumference of the top cover. A fixing plate is provided on the lower side of the tooling table. A supporting rotating sleeve is fixedly mounted on one side of the fixing plate. A rotating shaft is vertically mounted on the end face of the supporting rotating sleeve. On one side of the coating box, a functional mechanism for cleaning and coating is provided on the other side of the fixed plate opposite to the supporting rotating sleeve. Although this utility model achieves coating by driving the optical glass to move horizontally in a circular motion through a rotating motor and combining it with a coating spraying unit, the spraying range and uniformity of the coating spraying unit may be affected by various factors during the actual coating process. During the rotation of the tooling components, the coating spraying unit may generate a large centrifugal force due to the shift of the center of gravity. If there is no limit to the optical glass, even if the optical glass is rotating, there may still be problems with uneven coating thickness, which will affect the quality of the optical glass.

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0014] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a coating device for optical glass manufacturing, including a device base 1, a pressing assembly 2, a feeding assembly 3, and an air blowing assembly 4; the pressing assembly 2 includes a support frame 21, a pressing drive cylinder 22, a pressing head 23, an optical glass carrier cylinder 24, and a carrier cylinder rotation motor 25. The support frame 21 is bolted to the device base 1, and the pressing drive cylinder 22 is bolted to the top of the support frame 21. The output end of the pressing drive cylinder 22 is provided with a cylinder body connecting seat 221, which is connected to the pressing head 23. The bottom of the pressing head 23 has a pressing... The head positioning groove 231, the bottom wall of the optical glass carrier cylinder 24 is provided with a bearing seat 243, the carrier cylinder rotation motor 25 is installed inside the device base 1, the output end of the carrier cylinder rotation motor 25 is provided with a conveyor belt 251, the other end of the conveyor belt 251 is connected to the bearing seat 243 for transmission, and the output end of the carrier cylinder rotation motor 25 is connected to the optical glass carrier cylinder 24 through the conveyor belt 251; the optical glass carrier cylinder 24 is located below the pressing head 23, the inner wall of the optical glass carrier cylinder 24 is provided with a carrier platform anti-slip pad 241, and the bottom is provided with a carrier platform positioning hole 242.
[0015] In this case, the device base 1 serves as the basic support platform for the device, providing a stable installation reference for the pressing assembly 2, feeding assembly 3, etc., ensuring the stability of the overall structure. The support frame 21 of the pressing assembly 2 supports the main structure of components such as the pressing drive cylinder, ensuring the installation accuracy and stability of the pressing assembly. The pressing drive cylinder 22 provides pressing power, driving the pressing head 23 to rise and fall, thereby pressing or releasing the optical glass. The cylinder body connecting seat 221 is a transition component connecting the pressing drive cylinder and the pressing head 23, enhancing the firmness of the connection between the two and ensuring stable power transmission. The pressing head 23 is the pressing component that directly contacts the optical glass. The pressing head positioning groove 231 is adapted to the top shape of the optical glass, precisely defining the glass position and preventing displacement during pressing. The optical glass carrier cylinder 24 holds the optical glass to be coated; the anti-slip pad 241 on the carrier platform increases the friction between the glass and the cylinder wall to prevent the glass from sliding when rotating; the positioning hole 242 on the carrier platform matches the bottom structure of the glass to improve the placement accuracy; the bearing seat 243 supports the rotation of the carrier cylinder to ensure a smooth rotation process; the carrier cylinder rotation motor 25 provides rotational power; the conveyor belt 251 transmits the motor power to the carrier cylinder, driving the optical glass to rotate at a uniform speed. In conjunction with the coating operation, the feeding component 3 realizes the automated conveying of the optical glass, sending the glass to be processed into the carrier cylinder to improve the feeding efficiency; the air blowing component 4 sprays air through the air blowing head 43 to clean the dust and impurities on the surface of the optical glass, ensuring that the glass surface is clean before coating and improving the coating quality.
[0016] Workflow: The feeding drive 33 of the feeding assembly 3 drives the optical glass to move along the feeding track 32, conveying the glass to be coated into the optical glass carrier cylinder 24. The bottom of the glass is embedded in the positioning hole 242 of the carrier platform, and the side wall is attached and fixed to the anti-slip pad 241 of the carrier platform. The pressing and positioning pressing drive cylinder 22 is started, pushing the pressing head 23 down. The positioning groove 231 of the pressing head is adapted to the top of the glass, pressing the glass tightly in the carrier cylinder to ensure that the glass position is fixed. The sliding seat 42 of the cleaning blowing assembly 4 is adjusted along the sliding track 41, and the blowing head 43 sprays airflow at the glass surface to clean the surface impurities. The rotating coating carrier cylinder rotation motor 25 is started, driving the bearing seat 243 and the optical glass carrier cylinder 24 to rotate at a constant speed through the conveyor belt 251, and simultaneously opening the coating mechanism (not shown in the figure) to uniformly spray the rotating glass surface. After the unloading coating is completed, the pressing drive cylinder drives the pressing head 23 to rise, and the feeding assembly 3 takes out the coated glass from the carrier cylinder, completing a single coating operation.
[0017] Effects: The rotating motor 25 of the bearing cylinder drives the glass to rotate at a uniform speed. With the dual positioning of the pressing head positioning groove 231 and the bearing cylinder, the glass is prevented from shifting during rotation, ensuring uniform coating thickness and enhancing the stability of the glass. The combination of the anti-slip pad 241 of the bearing platform and the pressing head 23 solves the problem of glass slippage in traditional devices. Even at high speeds, the glass can maintain a stable position, improving operational efficiency. The feeding component 3 enables automated feeding, reducing manual operation steps. The air blowing component 4 cleans the glass surface in advance, saving manual cleaning time and significantly improving overall work efficiency. The pressing head positioning groove 231 and the elastic buffer design prevent the glass surface from being scratched or crushed during pressing, improving product yield. The structure is stable and easy to maintain. All components are connected by bolts, and with the smooth transmission of the bearing seat 243, the device operates stably. Disassembly and replacement of components are more convenient during later maintenance.
[0018] The feeding assembly 3 includes a feeding bracket 31, a feeding track 32, and a feeding drive 33. The feeding bracket 31 is fixed to the side of the pressing assembly 2, the feeding track 32 is set on the feeding bracket 31, and the feeding drive 33 is connected to the feeding track 32. The air blowing assembly 4 includes a sliding track 41, a sliding seat 42, and an air blowing head 43. The sliding track 41 is set on the device base 1, the sliding seat 42 is slidably engaged with the sliding track 41, and the air blowing head 43 is installed on the sliding seat 42. The device base 1 is provided with a positioning plate 11 and a connecting positioning plate 12, which are magnetically engaged.
[0019] In this case, the feeding bracket 31 of the feeding assembly 3 fixes the support structure of the feeding track 32, ensuring that the installation height and angle of the feeding track 32 are adapted to the inlet of the optical glass carrier cylinder 24, providing a stable reference for feeding. The feeding track 32 is the conveying channel for optical glass, guiding the glass to move accurately into the carrier cylinder and avoiding glass deviation during conveying. The feeding drive component 33 provides conveying power to the optical glass, such as a cylinder or electric push rod, pushing the glass to move along the feeding track 32, realizing automated feeding and replacing manual operation. The sliding track 41 of the air blowing assembly 4 provides a moving guide for the sliding seat 42 and supports the adjustment of the air blowing head 43. The position is adapted to the cleaning needs of optical glass of different sizes. The sliding seat 42 is a movable carrier for mounting the air blowing head 43. It can slide back and forth or left and right along the sliding track 41 to adjust the relative position of the air blowing head 43 and the glass. The air blowing head 43 is a component that sprays high-pressure airflow to clean dust, debris and other impurities on the surface of the optical glass, ensuring that the glass surface is clean before coating and avoiding impurities from affecting the coating quality. The positioning plate 11 and the connecting positioning plate 12 of the device base 1 component are magnetically engaged to realize the quick positioning and fixation of the component, enhance the connection stability of the device base and other components such as the bracket frame, and facilitate the quick disassembly, adjustment or maintenance of the component.
[0020] The shape of the positioning groove 231 of the pressing head is adapted to the top shape of the optical glass to be coated, and an elastic buffer pad is attached to the bottom of the pressing head 23 to avoid damaging the surface of the optical glass.
[0021] In this case, the shape of the positioning groove 231 of the pressing head is precisely matched with the top shape of the optical glass to be coated, so that the top of the optical glass can be embedded in the groove to form a close-fitting positioning, effectively limiting the lateral displacement of the glass. During the process of the optical glass carrier cylinder 24 driving the glass to rotate for coating, it can prevent the glass from shifting or shaking due to centrifugal force, ensuring that the glass is always in the preset coating position, providing a basic positioning guarantee for uniform coating. The optical glass material is relatively brittle and the surface precision requirements are extremely high. The elastic buffer pad is made of flexible silicone and other materials, which can generate elastic deformation during the pressing process, buffering the rigid pressure brought by the pressing drive cylinder 22, avoiding scratches, indentations and other damage caused by the pressing head 23 directly contacting the glass surface, and ensuring the integrity of the glass surface.
[0022] The inner diameter of the optical glass carrier cylinder 24 is adapted to the outer diameter of the optical glass to be coated, and the anti-slip pad 241 of the carrier platform is made of silicone.
[0023] In this case, the inner diameter of the optical glass carrier cylinder 24 is precisely matched with the outer diameter of the optical glass to be coated, which can form a limit from the side wall of the glass. Combined with the top positioning of the positioning groove 231 of the pressing head, it can achieve all-round wrapping positioning of the optical glass. The anti-slip pad 241 of the carrier platform is made of silicone material, which has good anti-slip performance. It can increase the friction between the optical glass and the inner wall of the carrier cylinder, effectively preventing the glass from sliding relative to each other during rotation, pressing and other processes, and ensuring the glass position is fixed.
[0024] The discharge end of the feeding track 32 corresponds to the top of the optical glass carrier cylinder 24, the air blowing head 43 blows air towards the opening of the optical glass carrier cylinder 24, and the sliding seat 42 can be adjusted along the sliding track 41.
[0025] In this case, the corresponding arrangement of the discharge end of the feeding track 32 and the upper part of the optical glass carrier cylinder 24 enables precise unloading and guidance of the optical glass. After the optical glass to be conveyed moves along the feeding track 32 to the discharge end, it can fall directly into the optical glass carrier cylinder 24 below without additional direction adjustment, reducing the risk of deviation during glass conveying. The air blowing head 43 sprays air towards the opening of the optical glass carrier cylinder 24, which can be precisely aligned with the placement area of the optical glass to be coated. After the glass is placed into the carrier cylinder and before pressing and positioning, the airflow directly blows the glass surface and the opening of the carrier cylinder. The surrounding dust, debris, and other impurities are effectively removed, ensuring targeted cleaning and preventing residue from affecting coating adhesion and surface smoothness. The sliding seat 42 can be adjusted along the sliding track 41 to flexibly adjust the position of the blowing head 43 according to the size and specifications of the optical glass and the specific opening range of the carrier cylinder, ensuring that the blowing range fully covers the glass surface and avoiding cleaning dead corners. For different specifications of optical glass or carrier cylinders, there is no need to replace the blowing component 4; it can be adapted simply by adjusting the position of the sliding seat 42, which improves the versatility and adaptability of the device and reduces equipment debugging and maintenance costs.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
