Description

Technical Field

[0001] This application relates to the field of lens processing technology, and in particular to a surface cleaning device for lens processing. Background Technology

[0002] Lenses, as optical elements used to control the propagation and focusing of light, play a crucial role in many fields, including eyeglasses, photography, optical instruments, medical devices, laser processing, and are also widely used in optical communications, optical sensors, and solar energy. Currently...

[0003] The lens manufacturing process is a complex and delicate process, which mainly includes steps such as raw material cutting, deburring, mold preparation and casting, preliminary processing, fine processing, grinding and polishing, coating treatment, and quality inspection.

[0004] Currently, during the mechanical processing of lenses, such as grinding and polishing, to prevent the high temperatures during grinding from affecting the surface quality of the lens, coolant is usually continuously sprayed during the operation to reduce the impact of temperature rise. After grinding and polishing, coolant will remain on the lens surface, which is not conducive to subsequent operations such as coating and marking.

[0005] Currently, the method for cleaning the coolant on the lens surface is to wipe it manually with a clean cloth. This can quickly remove the coolant, but the contact with the lens surface during the wiping process can cause scratches, requiring rework and, in severe cases, rendering the lens unusable, thus increasing lens processing costs. Summary of the Invention

[0006] To address the aforementioned problems, this application aims to provide a surface cleaning device for lens processing. This device uses a blowing method to completely remove residual coolant from the lens surface without contacting the lens, effectively preventing scratches on the lens surface and improving the lens yield.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: a surface cleaning device for lens processing, wherein the lens is bonded to a jig and placed in a transfer tray by the jig, and the transfer tray is conveyed on a conveyor belt, characterized in that: the surface cleaning device is disposed on the side of the conveyor belt in the conveying direction, the surface cleaning device has a blowing mechanism that aligns with the lens in the conveying process, and further includes a lens driving mechanism that drives the upper and lower surfaces of the lens to align with the blowing mechanism.

[0008] Preferably, the surface cleaning device includes a support frame disposed on the side of the conveyor belt in the conveying direction, and the blowing mechanism is a blowing gun disposed on the support frame and facing the lens surface.

[0009] Preferably, the lens driving mechanism is a driving body vertically mounted on the support frame, and the bottom surface of the driving body is provided with a pneumatic gripper for holding the lens. The blow gun is symmetrically mounted on the support frame and aligned with the upper and lower surfaces of the lens in sequence.

[0010] Preferably, the purge nozzle of the purge gun has a flat structure, and a symmetrical arc-shaped guide fluid is provided in the middle of the purge nozzle.

[0011] Preferably, the inner wall of the purge port is configured as an arc-shaped surface structure.

[0012] The beneficial effects of this application are: the surface cleaning device rapidly blows away the coolant adhering to the lens surface through a blowing mechanism, causing the residual coolant to detach along the lens surface to the edge, maintaining the cleanliness of the lens surface and facilitating subsequent processing such as coating and marking. Simultaneously, the blowing process does not involve contact with the lens surface, effectively avoiding scratches and improving the lens yield.

[0013] By driving the lens up and down through the lens drive mechanism, the upper and lower surfaces of the lens can correspond to the blow mechanism at different blow stages, thereby performing a complete blow operation on both the upper and lower surfaces of the lens and improving the overall cleanliness of the lens.

[0025] 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.

[0026] See attached document Figures 1-11 The illustrated surface cleaning device for lens processing involves a lens 1 bonded to a fixture 2 and placed in a transfer tray 3 via the fixture 2. The lens 1 is typically bonded to the fixture 2 using a low-temperature alloy. During processing after bonding, the fixture 2 clamps the lens, preventing breakage caused by direct clamping. The fixture 2 is placed in the transfer tray 3 (which has a groove for embedding the fixture 2, limiting lens movement during transfer and preventing wear from contact with external components after tipping). By conveying the transfer tray 3 on a conveyor belt 4, the lens can be transferred between multiple processing steps, enabling continuous processing.

[0027] To address the problem of difficulty in removing coolant from the surface of lenses after machining, this application includes a surface cleaning device, such as... Figure 3 As shown, this surface cleaning device is positioned beside the conveyor belt 4 in the conveying direction. It has a blowing mechanism aligned with the lens 1 during the conveying process. After the lens is conveyed to the position directly opposite the blowing mechanism, the conveyor belt stops, and the blowing mechanism quickly blows away the coolant adhering to the lens surface. This causes the residual coolant to detach along the lens surface to the edge, maintaining the cleanliness of the lens surface and facilitating subsequent coating, marking, and other processing. Simultaneously, the blowing mechanism does not contact the lens surface during the blowing process, effectively preventing scratches and improving the lens yield.

[0028] To achieve complete blowing of both the upper and lower surfaces of the lens, the surface cleaning device also includes a lens driving mechanism that aligns the upper and lower surfaces of the lens 1 with the blowing mechanism. The blowing mechanism is fixed to ensure the stability of the blowing air source, while the lens driving mechanism drives the lens to move up and down, so that its upper and lower surfaces can correspond with the blowing mechanism at different blowing stages, thereby performing a complete blowing operation on both the upper and lower surfaces of the lens.

[0029] Specifically, such as Figure 3As shown, the surface cleaning device includes a support frame 5 disposed on the side of the conveyor belt 4 in the conveying direction, and the blowing mechanism is a blowing gun 6 disposed on the support frame 5 and facing the surface of the lens 1. Figure 4 As shown, when the lens is on the transfer tray and conveyed by the conveyor belt to the position corresponding to the blow gun 6 (preferably, a sensor corresponding to the transfer tray is provided on the support frame 5, not shown in the figure), the blow gun 6 is pneumatically activated, using an air source to blow away the coolant adhering to the lens for a certain period of time until the coolant on the lens surface is completely detached. A further preferred method is to use an air source with a certain temperature (lower than the melting point of the cryogenic alloy adhering to the lens, to prevent the lens from falling off after the cryogenic alloy melts), which simultaneously dries the lens surface during the blowing process, accelerating the cleaning of the surface coolant.

[0030] To achieve thorough cleaning of the upper and lower surfaces of the lens, such as Figure 3 As shown, the lens driving mechanism is a driving body 7 (preferably a driving cylinder structure) vertically mounted on the support frame 5. The bottom surface of the driving body 7 is provided with pneumatic grippers 71 for clamping the lens 1 (preferably distributed circumferentially, the pneumatic grippers 71 can clamp the side periphery of the lens after being pneumatically opened). The blow gun 6 is symmetrically arranged vertically on the support frame 5 and sequentially aligns with the upper and lower surfaces of the lens 1. Figure 7 As shown, when the lens is conveyed to the position corresponding to the blow gun 6, the upper blow gun 6 blows the upper surface of the lens diagonally downward. After blowing, the drive body 7 drives the pneumatic gripper 71 to move down, clamps the lens, moves it up and releases it from the transfer plate. Then, the lower blow gun 6 blows the bottom surface of the lens diagonally upward. After blowing is completed, the lens is moved down and placed in the transfer plate to continue to be conveyed forward, thus completing the complete blowing of the upper and lower surfaces of the lens.

[0031] like Figure 8 As shown, the blow port 6a of the blow gun 6 is typically a circular structure, while the lens has a certain surface area. Therefore, during blowing, only the area corresponding to the blow port 6a on the lens surface can be blown, while the sides of the lens cannot be fully blown away. It takes a long time to blow away the residual coolant on the sides of the lens, and some coolant may also remain. Therefore, to solve this problem, such as Figure 9-10 As shown, the blow port 6a of the blow gun 6 has a flat structure, and a symmetrical arc-shaped guide fluid 61 is provided in the center of the blow port 6a. The flat structure of the blow port 6a widens the blowing width, enhancing the blowing effect on both sides of the lens. Simultaneously, the arc-shaped sidewall of the guide fluid 61 directs the blowing air source to both sides, further enhancing the blowing effect on the surfaces of both sides of the lens and enabling rapid cleaning operations.

[0032] To further enhance the blowing effect on both sides of the lens, such as Figure 9As shown, the inner wall of the purge port 6a is configured with an arc-shaped surface structure. The purge air source can be further guided to both sides of the lens along the inner wall of this arc-shaped surface, thereby further improving the purge effect on the sides of the lens and increasing the purge efficiency of the lens surface.

[0033] The principle of this application is as follows: A cleaning device is provided on the side of the conveyor belt. When the coolant remaining on the surface of the lens is blown away, after the lens is conveyed to the position corresponding to the blow gun 6, the upper blow gun 6 first blows the upper surface of the lens. After the blowing is completed, the pneumatic gripper 71 moves down, clamps the lens, moves it up and separates it from the transfer tray. Then the lower blow gun 6 blows the lens diagonally upward to the bottom surface of the lens. After the blowing is completed, the lens is moved down and placed in the transfer tray to continue to be conveyed forward, thereby completing the complete blowing operation on the upper and lower surfaces of the lens.

[0034] 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.
