Description

Technical Field

[0001] This utility model relates to the field of eyeglasses production equipment technology, and in particular to a lens cleaning device for 3D eyeglasses production. Background Technology

[0002] In the manufacturing process of 3D glasses, lens cleaning is a crucial and indispensable post-processing step. After undergoing a series of processing steps such as cutting, grinding, coating, and polarization bonding, the surface of the lenses inevitably accumulates tiny plastic dust, metal shavings, oil stains, fingerprints, and airborne particles attracted by electrostatic attraction. If these contaminants are not thoroughly removed, they will directly affect the optical performance (such as light transmittance and clarity) and appearance quality of the product, leading to a decrease in yield. Currently, the cleaning of 3D glasses lenses in production workshops mainly relies on manual wiping or general ultrasonic cleaning machines. The existing technology has the following problems:

[0003] Existing manual wiping cleaning methods are extremely inefficient and cannot meet the needs of large-scale mass production, becoming a bottleneck process in the production line. Secondly, the cleaning quality is highly unstable, relying entirely on the operator's sense of responsibility and skill level, easily leading to problems such as missed areas, uneven wiping, and scratches. Meanwhile, existing general-purpose ultrasonic cleaning machines, which place a large number of lenses in a cleaning basket and immerse them entirely in the cleaning solution for ultrasonic cleaning, improve efficiency to some extent, but are not designed specifically for the characteristics of 3D glasses lenses. Their disadvantages are also obvious: First, the lenses stack and collide with each other in the cleaning basket, easily causing scratches and wear on the lens surface, especially the polarizing film, resulting in defective products. Second, the rinsing and drying processes after cleaning are often separated, requiring multiple transfers of the workpieces, which not only increases the number of steps and time, but also increases the risk of contamination and damage during the transfer process.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a lens cleaning device for 3D glasses production includes a cleaning platform plate 1. A lens conveying mechanism 2 is arranged around the outer side of the cleaning platform plate 1. The cleaning platform plate 1 has a vertically penetrating mounting hole 11. An ultrasonic cleaner housing 3 is fixedly installed in the inner ring of the mounting hole 11. A rinsing mechanism 4 and a drying mechanism 5 are arranged on the top front side of the cleaning platform plate 1. The drying mechanism 5 is located behind the rinsing mechanism 4 and in front of the mounting hole 11. The lens conveying mechanism 2 includes two front and rear drive wheels 21 and two left and right L-shaped brackets 25. The two drive wheels 21 are rotatably installed at the front and rear ends of the cleaning platform plate 1, respectively. The rear end of the cleaning platform plate 1 is fixedly... A servo motor 22 is fixedly installed, and the output shaft of the servo motor 22 is fixedly connected to the left side of the rear drive wheel 21. A drive belt 23 is installed on the outer wall of the two drive wheels 21. A plurality of lens clamping mechanisms 24 are evenly arranged on the outer surface of the drive belt 23. Two L-shaped brackets 25 are fixedly installed at the bottom of the cleaning platform plate 1 and located on the left and right sides of the mounting through hole 11. An L-shaped hanging rod 26 is fixedly installed at the bottom of the horizontal position of each of the two L-shaped brackets 25. Movable pressure rollers 27 are rotatably installed at the opposite ends of the horizontal position of each of the two L-shaped hanging rods 26. The outer walls of the two movable pressure rollers 27 are in contact with the surface of the drive belt 23. Each of the plurality of lens clamping mechanisms 24 includes a base plate 241. Several base plates 241 are uniformly fixedly mounted on their tops with several sets of two adjacent metal elastic clamps 242. The metal elastic clamps 242 can adaptively adjust the clamping force according to the lens thickness, and rubber pads 243 are fixedly mounted on the opposite surfaces of the two metal elastic clamps 242. A cleaning box 31 penetrating the top of the ultrasonic cleaner housing 3 is fixedly mounted in the inner cavity of the ultrasonic cleaner housing 3. Two movable pressure rollers 27 are located in the inner cavity of the cleaning box 31. Several ultrasonic generators 32 are arranged on the bottom rear side of the cleaning box 31. The ultrasonic generators 32 operate at a frequency of 40kHz. Deionized water and a 5% volume ratio of neutral optical cleaning agent are injected into the cleaning box 31. The liquid level is maintained at 4 / 5 of the depth of the cleaning tank 31 and is monitored in real time by a liquid level sensor. A drain pipe 33 is fixedly connected to the bottom front side of the cleaning tank 31, which runs through its inner cavity. Pressure rollers 34 are fixedly installed on both the front and rear sides of the bottom of the ultrasonic cleaner housing 3. The bottom of the two pressure rollers 34 are in contact with the side of the drive belt 23 away from the lens clamping mechanism 24. Two pressure rollers 12 are fixedly installed on the top of the cleaning platform plate 1. The two pressure rollers 12 are located on the front and rear sides of the mounting through hole 11, respectively. The front pressure roller 12 is located on the rear side of the rinsing mechanism 4. The top of the two pressure rollers 12 are in contact with the side of the drive belt 23 away from the lens clamping mechanism 24.

[0025] In use, the two lenses of a pair of 3D glasses are aligned with the two sets of opposing metal elastic clamps 242 on the left and right sides of the top of the base plate 241 and inserted into the glasses. The friction of the rubber pads 243 is used to improve the stability of the clamping. The rubber pads 243 can be made of silicone rubber, which has both high and low temperature resistance, to prevent the hot air from affecting the stability during subsequent air drying. During installation, the lens clamping mechanisms 24 are positioned behind the top of the cleaning platform plate 1 where the drive belt 23 is located. When the servo motor 22 is started, it controls the drive wheel 21 to rotate in a step-by-step manner. The servo motor 22 is controlled by the PLC control system, which drives the drive wheel 21 to rotate once every 5 seconds. This causes the drive belt 23 to drive the lens clamping mechanisms 24 through the cleaning, rinsing, and air drying stations in sequence, thereby controlling the lens clamping mechanisms 24 on the top of the drive belt 23 on the outer wall of the two drive wheels 21 to move in a step-by-step manner. The ultrasonic cleaner moves forward, allowing the lenses it holds to be guided by the pressure roller 12 and pressed by the movable pressure roller 27 at the horizontal position of the L-shaped hanging rod 26, immersing them one by one in the inner cavity of the cleaning tank 31. The movable pressure roller 27 is positioned on the left and right sides of the base plate 241, which does not affect the conveying stability of the drive belt 23. The cleaning tank 31 is pre-filled with cleaning fluid. When the ultrasonic generator 32 is working, it will generate high-frequency vibration, forming countless tiny cavitation bubbles in the cleaning fluid. The impact force generated by the bursting of these bubbles can completely remove stubborn stains such as dust and oil from the surface of the lenses. The cleaning fluid can be replaced periodically by opening the valve on the outer wall of the drain pipe 33. The pressure roller 24 at the bottom of the ultrasonic cleaner housing 3 can effectively prevent the drive belt 23 from wearing with the ultrasonic cleaner housing 3. Similarly, the pressure roller 12 can also prevent the drive belt 23 from wearing with the front and rear edges of the top of the cleaning tank 31.

[0026] like Figure 5 As shown, the rinsing mechanism 4 includes a rinsing tank 41. A water pump 42 is fixedly installed on the top of the rinsing tank 41. Infusion pipes 43 are fixedly connected to both the front and rear sides of the output end of the water pump 42. The other ends of the two infusion pipes 43 penetrate into the inner cavity of the rinsing tank 41 and are fixedly connected to infusion horizontal pipes 44. Several atomizing nozzles 45 are evenly fixedly connected below the opposite surfaces of the two infusion horizontal pipes 44. The rinsing water pressure provided by the water pump 42 is 0.2–0.4 MPa, and the atomizing nozzles 45 generate… The atomized particles have a diameter between 50 and 100 μm to ensure uniform rinsing without impacting the lens displacement. A drain pipe 46 is fixedly connected to the left side of the rinsing box 41, which runs through its inner cavity. Conveyor belt inlet and outlet holes that run through its inner cavity are opened on both the front and rear sides of the rinsing box 41. The drive belt 23 passes through the two conveyor belt inlet and outlet holes, and splash curtains 47 are fixedly installed on the top of the inner walls of the two conveyor belt inlet and outlet holes. The splash curtains 47 are made of 0.5 mm thick silicone material, which has good flexibility and wear resistance.

[0027] After being ultrasonically cleaned by the cleaning fluid in the cleaning tank 31, the lens moves forward with the drive belt 23. After passing through the splash curtain 47, it moves step by step to the area between the two infusion horizontal pipes 44. Several atomizing nozzles 45 are installed on the opposite side of the two infusion horizontal pipes 44, tilted towards the middle. By starting the water pump 42, the external rinsing fluid is drawn in and injected into the infusion horizontal pipes 44 through the two infusion pipes 43. Finally, the atomized liquid is sprayed from the several atomizing nozzles 45 onto the lens clamping mechanism 24. The atomized liquid can remove the dirt remaining on the lens surface and prevent the clamped lens from loosening. The water pressure is also more gentle. The two 0.5mm thick silicone splash curtains 47 in the inlet and outlet holes of the conveyor belt can prevent water from splashing out and prevent the clamped lens from shifting. Finally, the wastewater generated by rinsing can be discharged into the sewage pipe through the drain pipe 46.

[0028] like Figure 6 As shown, the air drying mechanism 5 includes an air drying box 51. The air drying box 51 has inlet and outlet holes on both the front and rear sides. The rear inlet and outlet hole is connected to the inner cavity of the rinsing box 41. The top of the air drying box 51 has an installation hole 52 that passes through its inner cavity. A heater 53 is fixedly installed in the inner ring of the installation hole 52. The outlet temperature of the heater 53 is controlled at 60℃±5℃. It has a built-in temperature sensor and an overheat protection switch to prevent the lens or clamping mechanism from being damaged by excessive temperature. A dust filter plate 54 is fixedly installed at the bottom air inlet of the heater 53.

[0029] After being rinsed in the rinsing chamber 41, the lenses are transported to the drying chamber 51 by the drive belt 23. They are then quickly dried by the hot air blower 53 installed in the mounting hole 52. The hot air blower 53 has a design with a heating tube at the bottom and an exhaust fan at the top. The exhaust fan draws in outside air after it has been filtered through the dust filter plate 54, and then heats it with the heating tube and blows it onto the passing lenses to achieve the drying function. Finally, the dried lenses are moved out step by step by the drive belt 23 to the front of the drying chamber 51. The staff can directly wear dust-free gloves to remove the lenses for collection. The lens clamping mechanism 24, which removes the lenses, can then be transported backward by the drive belt 23 under the cleaning platform plate 1 and moved back to the top of the cleaning platform plate 1 one by one to repeat the lens clamping work.

[0030] The working principle of the lens cleaning device used in the production of 3D glasses will be explained in detail below.

[0031] like Figure 1-5As shown, during use, the two lenses of a pair of 3D glasses are aligned with the two sets of opposing metal elastic clamps 242 on the left and right sides of the top of the base plate 241 and inserted into the glasses. The rubber pads 243 enhance the stability of the clamping. The rubber pads 243 can be made of silicone rubber, which has both high and low temperature resistance, preventing the hot air from affecting the stability during subsequent drying. During installation, the lens clamping mechanisms 24 are positioned behind the top of the cleaning platform plate 1 where the drive belt 23 is located. When the servo motor 22 is started, it controls the drive wheel 21 to rotate in a step-by-step manner, thereby controlling the lens clamping mechanism 24 on the top of the drive belt 23 on the outer wall of the two drive wheels 21 to move forward in a step-by-step manner, allowing the clamped lens to pass through the guide of the pressure roller 12 and the L-shaped hanging rod 2. The movable pressure rollers 27 at the horizontal position press down on each lens, immersing them one by one inside the cleaning tank 31. The movable pressure rollers 27 are positioned on the left and right sides of the base plate 241, without affecting the conveying stability of the drive belt 23. Cleaning fluid is pre-filled into the cleaning tank 31. When the ultrasonic generator 32 is working, it generates high-frequency vibrations, forming countless tiny cavitation bubbles in the cleaning fluid. The impact force generated by the bursting of these bubbles can thoroughly remove stubborn stains such as dust and oil from the lens surface. The cleaning fluid can be replaced periodically by opening the valve on the outer wall of the drain pipe 33. The pressure roller 34 at the bottom of the ultrasonic cleaner housing 3 effectively prevents wear between the drive belt 23 and the ultrasonic cleaner housing 3. Similarly, the pressure roller 12 can also prevent wear between the drive belt 23 and the top of the cleaning tank 31. Wear occurs on the front and rear edges of the lens. After ultrasonic cleaning with cleaning fluid in the cleaning tank 31, the lens moves forward with the drive belt 23. After passing through the splash curtain 47, it moves stepwise to the area below the two infusion horizontal tubes 44. Several atomizing nozzles 45 are installed on the lower side of the two infusion horizontal tubes 44, tilted towards the middle. By starting the water pump 42, external rinsing fluid is drawn in and injected into the infusion horizontal tubes 44 through the two infusion pipes 43. Finally, the fluid is atomized and rinsed from the several atomizing nozzles 45 onto the lens clamping mechanism 24. The atomized liquid can remove residual dirt on the lens surface and prevent the clamped lens from loosening. The water pressure is also more gentle. The two splash curtains 47 inside the conveyor belt inlet and outlet are coated with a waterproof coating. The coating process is lightweight, preventing water splashes and avoiding displacement of the clamped lenses. Wastewater from the final rinsing is discharged into the sewage pipe via drain pipe 46. Lenses rinsed in the rinsing chamber 41 are then conveyed by drive belt 23 to the drying chamber 51, where a hot air blower 53 installed in the mounting hole 52 rapidly dries them. The hot air blower 53 features a lower heating element and an upper exhaust fan. The exhaust fan draws in outside air filtered through a dust filter plate 54, heats it, and blows it onto the passing lenses to achieve the drying function. Finally, the dried lenses are moved step-by-step by drive belt 23 to the front of the drying chamber 51, where workers wearing clean gloves can remove and collect them.The lens clamping mechanism 24, after removing the lens, can then follow the drive belt 23 as it passes under the cleaning platform plate 1 and continues to be conveyed backward, moving back one by one to the top of the cleaning platform plate 1 to repeat the lens clamping operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
