Description

Technical Field

[0001] This application relates to the field of lens processing technology, and in particular to an alloy cleaning furnace for lens fixing fixtures. Background Technology

[0002] A lens is an optical element used to control the propagation and focusing of light, and it has a wide range of applications in various fields. In optical instruments such as microscopes, telescopes, and spectrometers, lenses are used to focus, magnify, disperse, reflect, and refract light to enable the observation, measurement, and analysis of samples or targets. In photography and videography, lenses are one of the core components of cameras and camcorders, used to adjust the angle of incidence and focusing distance of light to obtain clear, sharp images and videos. Lenses are also used in laser processing, medical devices, optical communications, and optical sensors.

[0003] The current lens manufacturing process mainly includes steps such as design, material selection, rough grinding, fine grinding, polishing, coating, cleaning, and inspection. During the machining processes such as rough grinding, fine grinding, and polishing, to facilitate lens clamping, etc. Figure 1-2 As shown, a fixture is typically used to clamp the lens. The fixture has stepped grooves for inserting the lens. Currently, to ensure that the lens is securely embedded in the stepped grooves and to prevent the lens from falling off the fixture due to external forces during processing, a protective film is usually applied to the clamping surface of the lens. The film is then bonded to the stepped grooves of the fixture using a low-temperature alloy (melting point of about 50°C), thus securing the lens to the fixture and facilitating subsequent clamping and securing of the fixture.

[0004] Currently, after lens processing, the cryogenic alloy is dissolved again and the lens is disassembled from the fixture. Residue from the cryogenic alloy adheres to the fixture. If not thoroughly cleaned, this affects the firmness of the fixture's re-bonding of the lens, easily leading to lens detachment during later processing. Currently, the cryogenic alloy is typically dissolved using a water bath or oil bath. However, even after dissolution, the residue on the fixture cannot be completely cleaned, resulting in occasional lens detachment issues during later lens processing. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide an alloy cleaning furnace for lens fixing fixtures. Through ultrasonic cleaning and control of alloy temperature drop, the furnace can thoroughly clean the residue remaining on the fixture, thereby ensuring the tightness of the bonding between the fixture and the lens during later use and avoiding the problem of easy detachment due to mechanical external force during machining.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an alloy cleaning furnace for a lens fixing fixture, wherein the fixture has a stepped groove for bonding lenses with a low-temperature alloy, and the alloy cleaning furnace has a dissolving tank for dissolving the low-temperature alloy, characterized in that: a cleaning tank for ultrasonically cleaning the fixture is provided on one side of the dissolving tank, and the cleaning tank is arranged close to the dissolving tank.

[0007] Preferably, a channel for transferring the fixture is provided between the side walls of the dissolving tank and the cleaning tank.

[0008] Preferably, the fixture is detachably secured with a traction rope that drives it from the channel into the cleaning tank.

[0009] Preferably, the inner wall of the dissolving tank is provided with a slope along the bottom port of the channel.

[0010] Preferably, the port of the channel located within the cleaning tank extends into a closed tube that is immersed in the ultrasonic cleaning fluid.

[0011] The beneficial effects of this application are as follows: By setting a cleaning tank on one side of the melting tank of the alloy furnace, and placing the cleaning tank close to the melting tank, the tooling can be quickly transferred to the cleaning tank close to the melting tank after it has melted and separated from the lens. This effectively reduces the significant temperature drop of the tooling during the transfer to a separate ultrasonic cleaning tank. Furthermore, the ultrasonic re-cleaning thoroughly removes any remaining residue from the tooling, ensuring a firm bond between the tooling and the lens during later use and preventing it from easily detaching due to mechanical forces during machining.

[0020] In the diagram: 23 - cover; 5 - lens. Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] See attached document Figures 1-3 The diagram shows an alloy cleaning furnace for a lens fixing fixture. The fixture 1 has a stepped groove 1a for bonding the lens with a low-temperature alloy. The alloy cleaning furnace 2 has a dissolving tank 21 for dissolving the low-temperature alloy. The processed lens and fixture are placed in the dissolving tank 21. The low-temperature alloy is dissolved by heating, such as in a water bath, so that the lens is separated from the fixture. At the same time, the fixture is cleaned by the action of the water bath.

[0023] To address the issue of low-temperature alloy residue remaining on the fixture after water bath dissolution and cleaning, which affects the subsequent stable bonding of lenses, such as... Figure 4 As shown, this application provides a cleaning tank 22 on one side of the dissolution tank 21 for ultrasonically cleaning the tool 1. The cleaning tank 22 is positioned close to the dissolution tank 21. After the tool detaches from the lens, it can be quickly transferred to the cleaning tank 22, which is close to the dissolution tank 21. Through ultrasonic cleaning, the residue remaining on the tool can be thoroughly cleaned, thus ensuring the firmness of the bond between the tool and the lens during later use and preventing the tool from easily falling off due to mechanical forces during machining.

[0024] The cleaning tank 22 is positioned close to the dissolving tank 21, so that after the mold is removed from the dissolving tank 21, it can be quickly placed in the ultrasonic cleaning liquid for cleaning. This effectively reduces the problem of the mold experiencing a large temperature drop during the process of transferring it to a separate ultrasonic cleaning tank, which makes it difficult to clean the re-cured alloy smoothly.

[0025] Typically, the melting tank 21 is topped with a cover 23. When transferring the melted tooling to the adjacent cleaning tank 22, the cover must be opened first before the tooling is transferred. After opening the cover, the tooling must first be removed from the melting tank 21 and then lowered into the cleaning tank 22. This transfer process takes a certain amount of time, and the tooling is exposed to room temperature (below the alloy's melting point), resulting in a temperature drop. This causes some residual alloy to solidify on the tooling, affecting its cleanliness. Therefore, to solve this problem, such as... Figure 5 As shown, a channel 2a for transferring the tooling 1 is provided between the adjacent side walls of the dissolving tank 21 and the cleaning tank 22. During ultrasonic cleaning, the tooling in the dissolving tank 21 can be transferred to the cleaning tank 22 through this channel 2a without opening the cover. This shortens the transfer time of the tooling, solves the problem of temperature drop of the low-temperature alloy, and ensures that the residual low-temperature alloy is not completely solidified when transferred to the ultrasonic cleaning solution, thus facilitating the complete cleaning of the residual alloy.

[0026] To facilitate the transfer of the fixture from channel 2a, such as Figure 6 As shown, a traction rope 3 is detachably attached to the fixture 1 to drive it from the channel 2a to the cleaning tank 22. Before the low-temperature alloy melts, the traction rope 3 is inserted from the channel 2a into the cleaning tank 22. After melting, the fixture can be quickly transferred from the channel 2a to the cleaning tank 22 by the traction of the traction rope 3, further shortening the transfer time and reducing the temperature drop effect.

[0027] The melting tank 21 is typically a cuboid structure. To prevent the fixture from getting stuck at the port of channel 2a during the traction transfer process via the traction rope 3, as follows: Figure 6 As shown, a ramp 2b is provided on the inner wall of the dissolving tank 21 along the bottom port of the channel. During the traction process, the tool can enter the channel 2a and the cleaning tank 22 along the ramp 2b, so that the tool can be transferred smoothly.

[0028] When performing the above-mentioned tooling transfer operation, it is not necessary to open the cover of the melting tank 21, so that the tooling still has a certain heat preservation effect in the melting tank. However, when entering the cleaning tank 22 from the channel 2a and immersing it in the ultrasonic cleaning solution, since the ultrasonic cleaning tank 22 is usually an open structure, the tooling will be in a room temperature environment for a certain period of time. During this period of time, there may still be solidification of residual alloy on the tooling (especially in winter). Therefore, to solve this problem, such as Figure 7 As shown, the port of the channel 2a located within the cleaning tank 22 extends into a sealed tube 4 that is immersed in the ultrasonic cleaning fluid. The bottom opening of this sealed tube 4 is immersed in the ultrasonic cleaning fluid. When transferring the fixture, immersion in the ultrasonic cleaning fluid through this sealed tube 4 effectively prevents alloy solidification that would occur if the fixture were in the ambient temperature environment of the cleaning tank 22. This further improves the cleaning operation for residual alloy on the fixture and enhances the cleanliness of the fixture after cleaning.

[0029] The principle of this application is as follows: before the low-temperature alloy is dissolved, the traction rope 3 is inserted into the cleaning tank 22 through the channel 2a and the closed tube 4. Then, the low-temperature alloy is dissolved, causing the lens to separate from the fixture. Then, by the traction of the traction rope 3, the fixture is directly immersed in the ultrasonic cleaning fluid along the slope 2b, the channel 2a and the closed tube 4 for ultrasonic cleaning. During the transfer process, the temperature drop of the residual alloy on the fixture is effectively reduced, thereby improving the cleanliness of the fixture.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
