Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and in particular to a cooling and shaping device for optical lenses after coating. Background Technology

[0002] Optical lens coating is a process of depositing a thin film of specific materials on the surface of a lens to improve its optical performance, such as increasing light transmittance, reducing reflectivity, and enhancing abrasion resistance and stain resistance. It is widely used in the production of various optical products such as camera lenses, eyeglass lenses, and optical instruments.

[0003] After coating, optical lenses are at a high temperature and usually require cooling. Currently, there are two main cooling methods commonly used in the industry: one is natural cooling, which relies on air heat conduction for natural heat dissipation; the other is dielectric cooling, which uses methods such as blowing cold air or spraying cold water to achieve rapid heat dissipation through direct contact between a low-temperature medium and the lens. Natural cooling is extremely slow, while dielectric cooling, although it can improve cooling efficiency, can damage the lens when the low-temperature medium comes into direct contact with the high-temperature lens, thus having limitations.

[0004] The reason for this problem is that the coated lens is in a high-temperature state. When a low-temperature medium comes into direct contact, the surface temperature of the lens will drop sharply in a short time, while the internal temperature of the lens cannot drop at the same time. This temperature difference will cause the surface and the inside of the lens to expand and contract differently, which will generate thermal stress. When the thermal stress exceeds the withstand limit of the lens material, it will cause the lens to crack or be permanently deformed, which has limitations. Utility Model Content

[0005] The purpose of this invention is to provide a cooling and shaping device for optical lenses after coating, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling and shaping device for optical lenses after coating, comprising a connecting chamber, a staged cooling chamber, a heating tube, and a blower; A coating machine is installed on one side of the connecting chamber, and the connecting chamber is connected to the coating machine; the staged cooling chamber is located on the other side of the connecting chamber, and the interior of the staged cooling chamber is divided into a low temperature zone, a medium temperature zone, and a high temperature zone from left to right; the heating tubes are located inside the staged cooling chamber, and the heating tube array is arranged in different temperature zones; the blower is located above the heating tubes.

[0007] Preferably, a support frame is fixedly mounted on one side of the connecting compartment, and a push-pull cylinder is fixedly mounted on the support frame.

[0008] Preferably, a sealing plate is slidably connected inside the support frame, and the output shaft of the push-pull cylinder is fixedly assembled with the sealing plate.

[0009] Preferably, a perforated plate is provided below the heating tube, and the perforated plate is fixedly assembled with the staged cooling chamber.

[0010] Preferably, the internal part of the stage cooling chamber is fixedly equipped with partition strips, the partition strips are arranged in an equidistant array, and the end of the perforated plate is fixedly assembled with the partition strips.

[0011] Preferably, the partition strip has an internal cavity, and a servo cylinder is fixedly mounted inside the cavity.

[0012] Preferably, a sealing sheet is fixedly installed inside the accommodating cavity. There are multiple sets of sealing sheets, and a wind baffle is provided between the sealing sheets. The sealing sheet and the wind baffle are in close contact.

[0013] Preferably, the connecting chamber and the stage cooling chamber are internally rotatably connected by a conveyor belt, which has a porous structure.

[0014] The technical effects and advantages of this utility model are as follows: This device uses a phased cooling chamber with low-temperature, medium-temperature, and high-temperature zones inside to gradually reduce the temperature of the lens, rather than rapidly cooling it directly. This avoids direct contact between the low-temperature medium and the high-temperature lens, alleviates the thermal stress caused by temperature shock, reduces the risk of lens cracking and deformation, and meets user needs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] This utility model provides, for example Figures 1 to 3 The cooling and shaping device for optical lens coating shown includes a connecting chamber 1, a staged cooling chamber 2, a heating tube 22, and a blower 23; A coating machine is installed on one side of the connecting chamber 1, and the connecting chamber 1 is connected to the coating machine; the stage cooling chamber 2 is installed on the other side of the connecting chamber 1, and the interior of the stage cooling chamber 2 is divided into a low temperature zone, a medium temperature zone and a high temperature zone from left to right; the heating tubes 22 are installed inside the stage cooling chamber 2, and the heating tubes 22 are arranged in array in different temperature zones; the fan 23 is installed above the heating tubes 22.

[0019] Example 1: In this example, after the coating machine completes the lens coating, the high-temperature lens enters the stage cooling chamber 2 through the connecting chamber 1. At this time, the push-pull cylinder 25 drives the sealing plate 26 to slide to the open state, ensuring that the lens smoothly enters the stage cooling chamber 2. The lens is carried by the conveyor belt 213 and is transported sequentially along the connecting chamber 1 to the high-temperature zone, medium-temperature zone, and low-temperature zone of the stage cooling chamber 2. Before the device starts, the target temperature of each temperature zone is preset according to the initial temperature, material, and cooling requirements of the lens. By adjusting the power of the heating tubes 22 arrayed in the corresponding temperature zone, the temperature of the high-temperature zone is slightly lower than the initial temperature of the lens, and the temperature of the medium-temperature zone is between that of the high-temperature zone. Between the low-temperature zone and the low-temperature zone, the temperature of the low-temperature zone is close to room temperature, forming a stable decreasing temperature gradient; the fan 23 works continuously, blowing the hot air heated by the heating tube 22 downwards, which is evenly dispersed through the perforated plate 27 and acts on the lens surface. At the same time, the porous conveyor belt 213 ensures air circulation on the lower surface of the lens, realizing synchronous heat exchange between the upper and lower surfaces of the lens. The separator 28 isolates each temperature zone, so that when multiple sets of lenses are cooled at the same time, different temperature zones will not affect adjacent temperature zones. It should be noted that the lens can pass through all temperature zones continuously and slowly, or it can stop briefly inside the temperature zone to achieve a better cooling effect and meet the needs of users.

[0020] like Figures 4 to 5 The cooling and shaping device for optical lens coating shown includes a connecting chamber 1, a staged cooling chamber 2, a heating tube 22, and a blower 23; A coating machine is installed on one side of the connecting chamber 1, and the connecting chamber 1 is connected to the coating machine; the stage cooling chamber 2 is installed on the other side of the connecting chamber 1, and the interior of the stage cooling chamber 2 is divided into a low temperature zone, a medium temperature zone and a high temperature zone from left to right; the heating tubes 22 are installed inside the stage cooling chamber 2, and the heating tubes 22 are arranged in array in different temperature zones; the fan 23 is installed above the heating tubes 22.

[0021] A support frame 24 is fixedly mounted on one side of the connecting chamber 1, and a push-pull cylinder 25 is fixedly mounted on the support frame 24. A sealing plate 26 is slidably connected inside the support frame 24, and the output shaft of the push-pull cylinder 25 is fixedly mounted to the sealing plate 26. A perforated plate 27 is provided below the heating tube 22, and the perforated plate 27 is fixedly mounted to the staged cooling chamber 2. A partition strip 28 is fixedly mounted inside the staged cooling chamber 2, and the partition strip 28 is arranged in an equidistant array. The end of the perforated plate 27 is fixedly mounted to the partition strip 28. A receiving cavity 29 is opened inside the partition strip 28, and a servo cylinder 210 is fixedly mounted inside the receiving cavity 29. A sealing sheet 211 is fixedly mounted inside the receiving cavity 29. There are multiple sets of sealing sheets 211, and a baffle plate 212 is provided between the sealing sheets 211. The sealing sheets 211 and the baffle plate 212 are tightly fitted together. A conveyor belt 213 with a porous structure is rotatably connected inside the connecting chamber 1 and the staged cooling chamber 2.

[0022] Example 2: In this example, the heating tube 22 is a finned electric heating tube 22. Its heating principle is as follows: The core of the finned electric heating tube 22 is that multiple sets of annular fins are integrally formed or welded on the outer surface of the metal heating tube 22 body. The fins are made of copper alloy. When the heating tube 22 is connected to the power supply, the internal heating wire heats up and the heat is quickly transferred to the heating tube 22 body. Then, the heat is transferred to the fins on the outer surface through the body. The fins can quickly heat the surrounding air to the target temperature. With the wind power of the fan 23, the air in the corresponding temperature zone can reach the preset temperature and remain stable in a short time to meet the user's needs. The coating machine is also equipped with a conveyor belt 213. The conveyor belt 213 has a slot inside. The optical lens is held by the fixture and locked in the slot. After the lens is coated, the conveyor belt 213 rotates and then enters the connecting chamber 1. Guided by the conveyor belt 213 inside the connecting chamber 1, it enters the stage cooling chamber 2. It should be noted that during the coating process, the sealing plate 26 inside the connecting chamber 1 is in a sealed state. The connecting chamber 1 is connected to the coating machine by bolts. The connecting chamber 1 is tightly fitted to the end of the coating machine to ensure that the coating process is in a vacuum state, which meets the user's needs.

[0023] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
