Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a rapid cooling device for coating in optical lens processing. Background Technology

[0002] In utility model patent application CN216838165U, published on June 28, 2022, entitled "A Coating Device for Optical Lens Production," this utility model discloses a coating device for optical lens production, belonging to the field of lens coating technology. The key technical points of the device are as follows: a coating device for optical lens production includes support frames, with support frames located on the left, right, and rear sides of the top of a base plate, totaling three support frames; a placement mold, with the placement mold located between the tops of the three support frames; cylinders, with cylinders installed on the left and right sides of the top of the base plate, and the piston rods of two cylinders penetrating the placement mold; a lower pressure plate, with a lower pressure plate located between the upper parts of the piston rods of the two cylinders; and coating cylinders, with seven coating cylinders located at the bottom of the lower pressure plate. Optical lenses are placed in the placement slots on the placement mold, which limit the movement of the optical lenses during the coating process, preventing displacement and resulting in a smoother coating.

[0003] In the aforementioned patents or prior art, after optical lenses are coated, the solvent in the film needs to evaporate and solidify. Traditional cooling methods often employ natural cooling or overall air cooling. Natural cooling is inefficient, while direct rapid cooling can cause excessive internal stress in the film due to the temperature difference between the inside and outside, leading to defects such as cracks, optical distortion, or even peeling. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for coating in optical lens processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling device for coating in optical lens processing, comprising an operating table, a base fixedly mounted on the operating table, multiple sets of support rods evenly distributed circumferentially on the base, a first mounting ring fixedly connected to the ends of the multiple sets of support rods, a fixing ring for limiting the lens fixedly connected to the upper end of the first mounting ring, the top surface of the first mounting ring for supporting the lens, a second mounting ring with adjustable height via a driving component above the fixing ring, a protective component surrounding the first and second mounting rings on the operating table, a cooling component inside the protective component, the cooling component including two symmetrically arranged air inlets with their input ends extending to the outside of the protective component, the output ends of the air inlets communicating with a gas distribution block, the gas distribution block being connected to the ends of the first and second mounting rings respectively via connecting hoses, multiple sets of air holes opened on the inner walls of the first and second mounting rings for spraying cooling gas onto the lens surface.

[0006] Furthermore, the protective assembly includes a protective cover fixedly installed on the top of the operating table, with the air distribution blocks fixedly installed on both sides of the inner wall of the protective cover, and the air inlet pipe penetrating the side wall of the protective cover and extending to the outside.

[0007] Furthermore, the front of the protective cover is provided with an openable and closable protective door, which is rotatably connected to the protective cover via a hinge.

[0008] Furthermore, handles are fixedly provided on the outer side of both sets of protective doors.

[0009] Furthermore, the outer wall of the protective cover is provided with sealing sleeves on both sides, and the air inlet pipe passes through the sealing sleeves and forms an airtight connection with the protective cover.

[0010] Furthermore, the drive assembly includes an electric push rod fixed to the top of the operating table, the output end of which is connected to a fixing plate, and the fixing plate is rigidly connected to the outer wall of the second mounting ring via a fixing rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the proposed rapid cooling device for optical lens coating is reasonable and has the following advantages:

[0012] (1) The device achieves differentiated temperature management for different areas of the lens through the gas path design, which greatly improves the quality of the cooling process. First, hot air is sprayed onto the lens surface through the pipe on one side to preheat or keep it warm. This promotes the gradual evaporation of the solvent in the coating layer or the initial low-temperature curing, avoiding defects such as cracks and fissures caused by the rapid increase in internal stress of the coating layer due to the sudden drop in temperature. At the same time, cold air is sprayed onto the lens from the other side of the device to quickly cool down the area that has completed the initial curing, achieving the final shaping. This significantly reduces the internal stress of the coating layer during the rapid curing process, effectively avoiding problems such as optical distortion and coating layer peeling caused by uneven thermal stress, thereby directly improving the consistency of the coating quality and the product yield of the lens.

[0013] (2) The device combines cooling function with safety protection structure. When the protective door is closed, the protective cover forms a relatively closed operating space, which fundamentally protects the safety of the operator and effectively prevents injury caused by high-speed airflow or possible lens breakage. At the same time, it avoids interference from the external environment to the precision cooling process. Secondly, the closed space can effectively maintain a specific internal cooling environment, reduce heat exchange with the outside, and ensure that the efficiency of hot and cold gas is concentrated on the lens itself, thereby improving cooling efficiency and gas utilization. The clamping system composed of the first mounting ring, the fixed ring and the liftable second mounting ring ensures the absolute stability of the lens under the impact of high-speed airflow and prevents any displacement or vibration.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A rapid cooling device for coating in optical lens processing includes an operating table 100. A base 200 is fixedly mounted on the operating table 100. Multiple sets of support rods 201 are evenly distributed circumferentially on the base 200. The ends of the multiple sets of support rods 201 are fixedly connected to a first mounting ring 202. A fixing ring 203 for limiting lens positioning is fixedly connected to the upper end of the first mounting ring 202. The top surface of the first mounting ring 202 is used to support the lens. A second mounting ring 204 with adjustable height via a driving assembly is provided above the fixing ring 203. The operating table 100 is equipped with... A protective assembly surrounds the first mounting ring 202 and the second mounting ring 204. The protective assembly contains a cooling assembly, which includes two symmetrically arranged air inlet pipes 301, the input ends of which extend to the outside of the protective assembly. The output ends of the air inlet pipes 301 are connected to the air distribution block 302. The air distribution block 302 is connected to the ends of the first mounting ring 202 and the second mounting ring 204 respectively through connecting hoses 303. The inner walls of the first mounting ring 202 and the second mounting ring 204 have multiple sets of air holes 304 for spraying cooling gas onto the lens surface.

[0024] The protective assembly includes a protective cover 101 fixedly installed on the top of the operating table 100. The air distribution blocks 302 are fixedly installed on both sides of the inner wall of the protective cover 101. The air inlet pipe 301 penetrates the side wall of the protective cover 101 and extends to the outside.

[0025] The protective cover 101 has an openable and closable protective door 102 on its front side, and the protective door 102 is rotatably connected to the protective cover 101 via a hinge.

[0026] Handles 103 are fixedly provided on the outer side of the two sets of protective doors 102.

[0027] The outer wall of the protective cover 101 is provided with sealing sleeves 300 on both sides, and the air inlet pipe 301 passes through the sealing sleeves 300 and forms an airtight connection with the protective cover 101.

[0028] The drive assembly includes an electric push rod 205 fixed to the top of the operating table 100. The output end of the electric push rod 205 is connected to a fixing plate 206. The fixing plate 206 is rigidly connected to the outer wall of the second mounting ring 204 through a fixing rod 207.

[0029] Working principle: During use, the electric push rod 205 is activated, which moves the second mounting ring 204 upward via the fixing plate 206 and the fixing rod 207. This facilitates the placement of the coated lens onto the first mounting ring 202, within the fixing ring 203. The first mounting ring 202 and the fixing ring 203 on it limit the lens from below and the side, preventing horizontal movement. After placement, the second mounting ring 204 is lowered via the drive assembly, pressing the lens down from above to securely clamp it. The protective door 102 is closed, creating a relatively sealed space within the protective cover 101. This not only ensures operational safety and prevents external interference but, more importantly, effectively maintains the internal cooling environment and improves cooling efficiency. The sealing sleeve 300 ensures the airtightness of the connection between the air inlet pipe 301 and the protective cover 101. Hot air is introduced into two sets of connecting hoses 303 located on the same side of the first mounting ring 202 and the second mounting ring 204. The hot air is distributed from the gas distribution block 302 to the corresponding mounting rings and sprayed onto the lens through the air holes 304 on the inner side of the rings. The heat promotes the evaporation of the coating solvent or causes the coating to undergo preliminary low-temperature curing, avoiding excessive stress or defects in the coating due to immediate and rapid cooling. At the same time, cold air is introduced into two other sets of connecting hoses 303 located on the other side of the first mounting ring 202 and the second mounting ring 204. The cold air is also sprayed onto the other side of the lens through the air holes 304, which facilitates rapid reduction of the temperature of the lens and the coating, completing the final curing and shaping. Gas enters from the external air inlet pipe 301, is divided by the gas distribution block 302, and the divided gas is transported to the first mounting ring 202 and the second mounting ring 204 through the connecting hoses 303. Finally, the gas is evenly and vertically sprayed from multiple air holes 304 on the inner walls of the two mounting rings onto the edge areas of the upper and lower surfaces of the clamped lens.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
