Description

Technical Field

[0001] This invention relates to the field of spectacle lens processing technology, specifically to a spectacle lens cleaning device for the cleaning stage after spectacle lens processing is completed. Background Technology

[0002] Eyeglass lenses, made of optical materials such as glass or resin, are transparent materials with one or more curved surfaces. After being polished, they are often assembled with eyeglass frames to form eyeglasses, used to correct the user's vision and obtain a clear field of vision.

[0003] Because individual eye prescriptions and the sizes and dimensions of eyeglass frames vary, each lens requires precise grinding to ensure a proper fit. To guarantee this precision, opticians are increasingly opting to send lenses to processing centers after obtaining the necessary prescription data. Automated grinding equipment replaces traditional manual, semi-automatic grinding, effectively improving processing efficiency and accuracy while reducing the optician's maintenance costs.

[0004] Because the processing may generate dust, debris, and grease on the lens surface, lenses processed in large quantities at the processing center need to be cleaned and maintained after processing before being returned to the dispensing center. The lens cleaning process requires specialized lens cleaning equipment. Existing specialized cleaning equipment for lens processing centers is often quite simple in structure, consisting of only a cleaning tank. Multiple processed lenses are either directly stacked in the cleaning tank or placed in the tank using a clamping structure. Since different lenses need to be cleaned, both of these placement methods create blind spots and dead zones during cleaning, resulting in poor cleaning performance, inconvenience for operators, and reduced practicality. Furthermore, the stacked lenses and the clamping structure can easily cause friction or scratches at the lens holding points. Additionally, this type of lens cleaning equipment suffers from low cleaning efficiency when handling large orders, requiring extended cleaning times, and the removal of the lenses after cleaning is also cumbersome. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide an eyeglass lens cleaning device that can overcome the defects in the above-mentioned technical background.

[0006] A spectacle lens cleaning device includes a cleaning tank and a cleaning disc used in conjunction with the cleaning tank;

[0007] The cleaning tank is installed inside the ultrasonic cleaning equipment. The cleaning tank is filled with a cleaning medium and uses ultrasonic waves as the main cleaning method. The cleaning tank is equipped with a fixing structure to fix the position of the cleaning disc.

[0008] The cleaning tray includes a tray frame and a cover plate;

[0009] The tray is a hollow frame structure with several inner grooves formed on its surface to serve as lens placement slots. The lens placement slots are sealed at the bottom by a soft silicone sheet. The soft silicone sheet has an arc-shaped protrusion formed on the inner surface of the slot, which serves as a support surface for the lens. The cross-section of the lens placement slot is larger than the circle of the lens to be cleaned. Several through holes are uniformly formed on the soft silicone sheet.

[0010] The cover plate includes a rigid plate body. The rigid plate body has a cover hole formed at the position corresponding to the lens placement slot, which matches the lens placement slot. A plastic cover plate is formed at the position of the cover hole. Multiple rod-shaped protrusions are formed on the bottom surface of the plastic cover plate. The rod-shaped protrusions are formed of soft silicone material. The multiple rod-shaped protrusions are in a ring shape and are concentrically set with the center of the arc-shaped protrusion.

[0011] As a further limitation, the cleaning medium is a lens-specific cleaning agent or deionized water.

[0012] As a further limitation, the cleaning tank is provided with at least two, one of which is the main cleaning tank, which is filled with lens-specific cleaning agent as the cleaning medium; and the other is an auxiliary cleaning tank and a rinsing tank, which has openings on both sides and is placed in a flowing water tank.

[0013] As a further limitation, the device is also equipped with a drying device as a drying structure.

[0014] As a further limitation, the fixing structure used to fix the cleaning disc in the cleaning tank is one of the following: hook structure, placement groove, insertion groove, and hoisting structure.

[0015] As a further limitation, the tray frame is provided with the same fastening structure on opposite sides. The fastening structure includes a matching male fastener and a female fastener. The male fastener is provided at the bottom side of the tray frame, and the female fastener is provided at the top side of the tray frame corresponding to the position of the male fastener. Different tray frames can be fastened together by the fastening structure after being stacked vertically.

[0016] The tray has staggered steps formed on the outer edges of its upper and lower surfaces to facilitate upper and lower stacking.

[0017] As a further limitation, the depth of the lens placement groove is 10-20 mm.

[0018] As a further limitation, the plastic cover plate has a detachable assembly structure on the cover hole.

[0019] As a further limitation, when the lens is placed on the curved protrusion surface, the curved protrusion is located at the outer edge of the top surface of the lens, and a gap of 0 to 3 mm is reserved between it and the lens surface.

[0020] Beneficial effects: The eyeglass lens cleaning device of the present invention can perform centralized cleaning of lenses after batch processing. It has a large single cleaning volume and can realize batch cleaning of multiple lenses with high cleaning efficiency. At the same time, during the cleaning process, the lenses are only in contact and restrained by soft silicone material, which can effectively prevent bump damage and fingerprints that may occur during manual cleaning. The covered cleaning disc structure makes it convenient to remove the lenses after cleaning. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. The described embodiments are merely some, not all, of the embodiments of this invention.

[0025] In the following embodiments, those skilled in the art will understand that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. All other embodiments obtained by one of ordinary skill in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0026] See Figure 1 , Figure 2A preferred embodiment of an eyeglass lens cleaning device includes a body with legs at the bottom for support and stability. If necessary, casters can also be provided on the legs to facilitate movement of the device.

[0027] The eyeglass lens cleaning device includes a back frame 1, which is vertically arranged and faces the operator, and a horizontally arranged table 15 on the upper part of the support leg. The back frame 1 and the table 15 are integrally formed, and the support leg is arranged on the outer edge of the table 15 to support the table 15 and the back frame 1, which serve as the worktable.

[0028] The surface of the frame 15 is a workbench, on which three work stations are arranged sequentially from left to right: the first cleaning tank 6 corresponding to position A, the second cleaning tank corresponding to position B, and the drying tank 13 corresponding to position C. These three work stations correspond to the process sequence of cleaning the processed lenses.

[0029] In this embodiment, the first cleaning tank 6 is the main cleaning tank, which consists of only one closed tank body, and the tank body is filled with a lens-specific cleaning agent as the cleaning medium.

[0030] The second cleaning tank serves as an auxiliary cleaning tank and rinsing tank. It includes an outer tank 10 and an inner tank 11. The inner tank 11 is located inside the outer tank 10. The outer tank 10 has openings on both sides and is connected to a circulating water circuit. The circulating water in the circulating water circuit is deionized water. A water storage tank and a purifier are also connected in series in the circulating water circuit. The water storage tank is used to replenish the consumed deionized water, and the purifier is used to remove impurities from the deionized water.

[0031] The upper opening of the air-drying trough 13 needs to be closed during the air-drying operation to improve the air-drying efficiency. An air outlet hole 12 is formed on the inner side wall of the trough body, and a drainage trough 14 is provided at the bottom of the air-drying trough 13 to facilitate the drainage of dripping water.

[0032] When the first cleaning tank 6, the second cleaning tank, and the drying tank 13 are assembled on the workbench surface, the spacing between adjacent tanks should be minimized to prevent excessive liquid dripping from the corresponding cleaning discs 7 during movement, which would affect the cleanliness of the workbench and increase the difficulty of cleaning. An ultrasonic generator is also formed within the frame 15. This ultrasonic generator is correspondingly located at the lower part of the outer tank 10 of the first and second cleaning tanks, and is used to provide ultrasonic waves of specific power to the first and second cleaning tanks to perform ultrasonic cleaning on items placed in the inner tanks 11 of the first and second cleaning tanks.

[0033] The back frame 1 is equipped with guide rails, including lifting rails 4 corresponding to the three working positions A, B, and C, and translation rails 3 for switching the working position between the three working positions. Both the lifting rails 4 and the translation rails 3 consist of two oppositely arranged rails, and to facilitate the arrangement of the two translation rails 3, the lifting rails 4 are arranged with an upper and lower staggered structure. Two pairs of suspension seats 2 are provided on the guide rails. When the suspension seats 2 are assembled on the two translation rails 3, the distance between them is slightly smaller than the width of the first cleaning tank 6 and the inner tank 11 of the second cleaning tank. The lower part of the suspension seats 2 is connected to the hangers 5 of different lengths to obtain a flush lower surface, so that when the object is hoisted by the fixing buckle at the lower end of the hanger 5, the corresponding object can remain horizontal while the two suspension seats 2 move synchronously.

[0034] In addition, a drive motor for driving the suspension seat 2 to move on the guide rail is also formed inside the back frame 1.

[0035] The suspension base 2 is used to suspend the loading container for the lens. This loading container consists of multiple stacked cleaning discs 7. In this embodiment, the number of stacked cleaning discs 7 is 6. The external structural design of the cleaning discs 7 is as follows: Figure 1 As shown, the cleaning disc 7 has a set of two hanging rings 9 formed on the left and right sides of the corresponding disc frame 16. The hanging rings 9 are connected and fixed to the fixing buckles at the ends of the hangers 5, so that the cleaning disc 7 can maintain a horizontal position for lifting and translating. On the front and back sides of the cleaning disc 7, there are two fastening structures 8, which are also set on the corresponding sides. The fastening structure 8 includes matching male and female buckles. The male buckle is set at the bottom side of the cleaning disc 7 on the corresponding disc frame 16 on that side, and the female buckle is set at the top side of the cleaning disc 7 on the corresponding disc frame 16 on that side, corresponding to the position of the male buckle. After the two cleaning discs 7 are stacked, the female buckle of the lower cleaning disc 7 can be flipped up and fastened to the male buckle of the upper cleaning disc 7 to fix the two cleaning discs 7 after stacking. By repeating this process, multiple cleaning discs 7 can be stacked and fixed. In order to improve the accuracy of the overlapping position of the cleaning discs 7 and prevent the fastening structure 8 from failing to be fastened after overlapping, this embodiment has matching overlapping misalignment steps formed on the outer edges of the upper and lower surfaces of the disc holder 16 of the cleaning discs 7.

[0036] The cleaning disc 7 serves as a container for the lenses to be cleaned. It includes a disc frame 16 as the main structural support and a cover plate 21 covering the surface of the disc frame 16. The disc frame 16 is a hollow frame structure made of stainless steel. Its hollow structure allows the disc frame 16 to have an open bottom connection 24 at the bottom and an open side connection 17 on the side. The bottom connection 24 and the side connection 17 allow the cleaning media in the first cleaning tank 6 and the second cleaning tank to quickly enter the cleaning space and act under the assistance of ultrasound. At the same time, when drying in the air drying tank 13, moisture is carried out through the air outlet 12.

[0037] Below the corresponding misaligned step plane, the tray 16 also has a tray surface. Multiple recessed grooves are arranged in an array on the tray surface as lens placement slots 23. Each lens placement slot 23 has a circular cross-section, with a diameter 1.2 times the original diameter of the lens to be cleaned. The depth of each slot 23 is 15mm. Each slot is used to place a single processed lens to be cleaned. The bottom of each slot 23 is open, and this open surface is sealed with a soft silicone sheet 20. The surface of the soft silicone sheet 20 has several uniformly formed through holes 20, and a convex arc-shaped protrusion is formed in the center of the sheet. This protrusion is used to place the lens to be cleaned. During placement, the lens is roughly centered on the concave side and then placed on the protrusion.

[0038] The cover plate 21 is used to cover the tray surface. It includes a rigid plate made of stainless steel. The plate has cover holes that match the lens placement slot 23 at the corresponding positions. Each cover hole position is formed with a plastic cover plate 18 in a detachable assembly manner. In this embodiment, the plastic cover plate 18 is made of plastic and is assembled into the cover hole by staggered step press fitting. Six rod-shaped protrusions 19 are formed on the lower surface of each plastic cover plate 18. These rod-shaped protrusions 19 are made of soft silicone material of the same material as the soft silicone sheet 20. The six rod-shaped protrusions 19 are arranged in a ring on the lower surface of the plastic cover plate 18 and are concentrically set with the center of the arc-shaped protrusion on the soft silicone sheet 20. When the lens to be cleaned is placed on the arc-shaped protrusion surface, the rod-shaped protrusions 19 are located at the outer edge of the top surface of the lens and a gap of 0 to 3 mm is reserved between them and the lens surface.

[0039] In this embodiment, the soft silicone sheet 20 and the rod-shaped protrusion 19 function to combine and limit the lens from the upper and lower surfaces by utilizing the softness and high contact friction properties of the soft silicone material, thus preventing damage during the cleaning process. At the same time, during the ultrasonic cleaning process, the material deformation and the continuous air bubbles generated during the ultrasonic cleaning process achieve a gentle rubbing motion on the lens surface using the soft silicone sheet 20 and the rod-shaped protrusion 19, which helps to remove impurities such as dust, debris, and grease.

[0040] In this embodiment, the cleaning device first places the lenses to be cleaned in the lens placement slots 23 on the cleaning discs 7. After placement, the multiple cleaning discs 7 to be cleaned are stacked and then fastened together. The discs are then assembled and connected to the suspension base 2 via the hanger 5. After assembly, the suspension base 2 moves along the guide rail according to the ABC working position sequence, and the lenses are cleaned sequentially using the first cleaning tank 6 and the second cleaning tank. After cleaning in the second cleaning tank, the lenses are transferred to the drying tank 13 for drying. Once drying is complete, the lenses can be collected.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
