Description

Technical Field

[0001] This utility model relates to the field of lens flipping technology, and in particular to a lens flipping device. Background Technology

[0002] In the manufacturing process of optical lenses, the lens's optical performance, surface quality, and geometric accuracy directly affect its final imaging effect and reliability. Lens processing typically includes several key steps such as rough grinding, fine grinding, polishing, and coating.

[0003] Lens flipping, as a fundamental yet crucial operation, aims to ensure that the processing equipment can uniformly and symmetrically process different surfaces of the lens by adjusting its front and back or top and bottom positions. For example, Chinese Patent Publication No. CN213706926U provides a lens flipping device, relating to the field of lens processing technology, including a frame, a slide, flipping components, and a drive mechanism. The slide is fixedly connected to the frame, with an open top and an opening at the bottom, and a belt for conveying the lens is provided on the slide. Two flipping components are arranged opposite each other, both rotatably connected to the frame and located within the openings, used to flip the lens. The drive mechanism is connected to each of the two flipping components and drives them to rotate towards or away from each other.

[0004] Currently, in traditional lens processing, especially in small-batch customization or laboratory-level production scenarios, lens flipping often relies on manual operation. That is, the operator uses tweezers, a suction pen, or holds the lens with their bare hands to remove it from the processing fixture, adjust it to the target position, and then fix it back in place. However, manual operation is highly dependent on the operator's experience. Novices may cause the lens to tilt, slip, or collide with the edge of the fixture due to unstable technique, while skilled workers may experience positioning deviations due to fatigue from long hours of work. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a lens flipping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a lens flipping device, including an operating table, on which columns are fixedly distributed at the four corners above the operating table, and the upper ends of the four columns are jointly mounted with the same top plate. A cylinder is installed at the center of the operating table, and a piston rod for driving is installed inside the cylinder. A lens holder is installed and fixed at the end of the piston rod, and a lens body is erected on the upper end of the lens holder. Support platforms are symmetrically distributed and fixed on both sides of the operating table. A cylinder two is fixedly installed on the top of the support platform via a bracket. A piston rod two for driving is provided inside the cylinder two, and a connecting block is fixedly installed at the end of the piston rod two. A motor is fixedly installed on the upper end of the connecting block via a bracket. A rotating shaft for driving is provided inside the motor, and a clamp is provided at the end of the rotating shaft. Two clamps distributed along both sides are arranged to clamp and install the lens body.

[0007] Preferably, an alignment block is fixedly installed on the motor shaft, and an alignment seat is fixedly installed at one end of the clamp, with the surface of the alignment block slidingly inserted and mated with the interior of the alignment seat.

[0008] Preferably, a positioning sleeve is fixedly installed on the surface of the positioning seat by a bracket, a positioning pin is slidably inserted inside the positioning sleeve, and a spring is wound around the surface of the positioning pin. The two ends of the spring are fixedly installed to the end face of the positioning sleeve and the end of the positioning pin, respectively.

[0009] Preferably, a positioning seat is fixedly installed on the surface of the alignment block, and the end of the positioning pin away from the spring is slidably inserted into the interior of the positioning seat.

[0010] Preferably, a guide rail sub-slide rail is fixedly installed at the lower end of the top plate, and anti-detachment blocks are fixedly installed at both the front and rear ends of the guide rail sub-slide rail. A guide rail sub-slide seat is slidably provided on the surface of the guide rail sub-slide rail.

[0011] Preferably, an extension plate is fixedly installed on one side of the guide rail slide, and a vacuum pump is fixedly installed at the lower end of the extension plate via a bracket. The air inlet flange of the vacuum pump is connected to a flexible hose.

[0012] Preferably, a cylinder three is fixedly installed at the lower end of the guide rail slide block, and a piston rod three for driving is provided inside the cylinder three. A suction cup is fixedly installed at the end of the piston rod three, and the air port of the suction cup is connected to the flange at the end of the hose away from the vacuum pump.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application: 1. In the positioning stage, cylinder one, located in the center of the operating table, pushes the lens holder upward, lifting the lens body to a suitable height. Then, cylinder two on both sides of the support platform moves synchronously, driving the clamp to move in opposite directions, thereby stabilizing the lens. After clamping, the lens holder automatically descends to make room and avoids interference with the flipping action. The servo motor drives the clamp to rotate synchronously under the command of the controller, enabling the lens to achieve a precise 180-degree flip. The entire process is smooth and requires no manual intervention, which not only improves the accuracy and consistency of the operation, but also significantly improves the efficiency of the lens processing or inspection process. 2. This solution uses a positioning block and a positioning seat to connect and position the clamp and the motor shaft, and a spring-loaded positioning pin to lock the connection, ensuring a stable connection. When processing lenses of different specifications or sizes, the operator only needs to manually pull the positioning pin to release the lock, allowing the original clamp to be removed and replaced with a suitable model. 3. This solution uses a guide rail slide mounted below the top plate to move the entire adsorption mechanism back and forth along the slide rail, allowing it to be precisely aligned with the lens position. The vacuum pump is connected to the suction cup via a hose. Driven by cylinder three, the suction cup descends and adheres to the lens surface, and then the vacuum adsorption function is activated to firmly grip the lens. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4A lens flipping device includes an operating table 1. Columns 11 are fixedly arranged at the four corners of the operating table 1. A common top plate 12 is mounted on the upper ends of the four columns 11. A cylinder 13 is mounted at the center of the operating table 1. A piston rod for driving is installed inside the cylinder 13, and a lens holder 110 is fixedly mounted at the end of the piston rod. A lens body 14 is mounted on the upper end of the lens holder 110. The extension and retraction of the piston rod of the cylinder 13 can adjust the height of the lens holder 110. When positioning the lens body 14, the lens holder 110 can lift the lens body 14. When rotating the lens body 14, the lens holder 110 can move down to avoid affecting the flipping of the lens body 14. Support platforms 15 are symmetrically distributed and fixed on both sides of the operating table 1. A cylinder 16 is fixedly installed on the top of the support platform 15 via a bracket. The cylinder 16 has a piston rod for driving inside, and a connecting block 17 is fixedly installed at the end of the piston rod. A motor 18 is fixedly installed on the upper end of the connecting block 17 via a bracket. The motor 18 has a rotating shaft for driving inside, and a clamp 19 is installed at the end of the rotating shaft. Two clamps 19 distributed on both sides are clamped and installed with the lens body 14. By extending the piston rod of the cylinder 16, the two clamps 19 can move in opposite directions, thereby clamping and positioning the lens body 14. When the motor 18 is powered on, the rotating shaft can rotate the clamps 19, thereby flipping the lens body 14. The motor 18 is a servo type. The two motors 18 have the same specifications and can be synchronously rotated at fixed points by a servo controller. The rotation range of each motor is 180 degrees, which can perform fixed-point flipping operations.

[0018] The motor 18 has a fixed alignment block 2 on its shaft and an alignment seat 21 on one end of the clamp 19. The surface of the alignment block 2 slides into and connects with the interior of the alignment seat 21. By connecting the alignment block 2 with the alignment seat 21, it is easy to assemble and disassemble the motor 18 and the clamp 19, and it is easy to replace the clamp 19 according to the size and specifications of the lens.

[0019] The positioning sleeve 22 is fixedly installed on the surface of the positioning seat 21 by a bracket. A positioning pin 23 is slidably inserted into the inside of the positioning sleeve 22. A spring 24 is wound around the surface of the positioning pin 23. The two ends of the spring 24 are fixedly installed to the end face of the positioning sleeve 22 and the end position of the positioning pin 23, respectively. The spring 24 can ensure the stable extension and resetting of the positioning pin 23.

[0020] The positioning block 2 has a positioning seat 25 fixedly installed on its surface. The end of the positioning pin 23 away from the spring 24 slides into the positioning seat 25. When the clamp 19 needs to be replaced, the positioning pin 23 is pulled so that the spring 24 can be stretched, thereby separating the positioning pin 23 from the positioning seat 25, and thus disassembling the clamp 19 from the motor 18.

[0021] The top plate 12 is fixedly installed with a guide rail 3 at its lower end. Anti-detachment blocks 31 are fixedly installed at both ends of the guide rail 3. A guide rail slide 32 is slidably provided on the surface of the guide rail 3. The guide rail slide 32 slides on the guide rail 3, which can realize the back and forth movement of the suction cup 41. When it is necessary to place or remove the lens body 14, it can be adsorbed with the lens body 14. The anti-detachment blocks 31 can prevent the guide rail slide 32 from sliding on the guide rail 3 and slipping off.

[0022] An extension plate 33 is fixedly installed on one side of the guide rail slide 32. A vacuum pump 34 is fixedly installed at the lower end of the extension plate 33 via a bracket. A hose 35 is connected to the air inlet flange of the vacuum pump 34. The vacuum pump 34 can perform an air extraction effect, so that the suction cup 41 has a stable adsorption effect after it is attached to the lens body 14.

[0023] Among them, a cylinder 3 4 is fixedly installed at the lower end of the guide rail slide 32. The cylinder 3 4 has a piston rod 3 for driving inside, and a suction cup 41 is fixedly installed at the end of the piston rod 3. The air port of the suction cup 41 is connected to the flange at the end of the hose 35 away from the vacuum pump 34. The piston rod 3 of the cylinder 3 4 extends and retracts, so that the suction cup 41 can contact the lens body 14, thereby achieving stable adsorption of the lens body 14. Cylinder 1 13, cylinder 2 16 and cylinder 3 4 are all servo models, which can be controlled by the servo controller through the central processing unit, so that the piston rod on the cylinder can be extended and retracted by a corresponding distance.

[0024] Working principle: The cylinder 13, mounted at the center of the operating table 1, drives the lens holder 110 to adjust vertically through the extension and retraction of its internal piston rod. When the lens body 14 needs to be positioned, the piston rod of the cylinder 13 extends, raising the lens holder 110 to a predetermined height, thereby stably supporting the lens body 14 and ensuring that the lens remains horizontal and stable in the initial position. This process provides a precise reference plane for subsequent clamping and flipping operations. When the lens needs to be flipped, the piston rod of the cylinder 13 retracts, driving the lens holder 110 to descend and move away, avoiding interference with the lens body 14 and ensuring the smooth progress of the flipping process. The entire lifting mechanism achieves precise positioning through servo control. The lifting function of the lens holder 110 not only improves operational safety but also reduces the risk of scratches on the lens surface, laying a solid foundation for subsequent steps. On the symmetrically distributed support platforms 15 on both sides of the operating table 1, cylinders 16 are fixed. The piston rods of cylinders 16 are connected to motors 18 via connecting blocks 17. A clamp 19 is installed at the end of the rotating shaft of motor 18. When the piston rod of cylinder 16 extends, the clamps 19 on both sides move in opposite directions to precisely clamp the edge of the lens body 14 and achieve firm positioning. Motor 18 is a servo type and is synchronously controlled by a servo controller to ensure that the two motors 18 operate at the same specifications and speed, driving the clamps 19 and the lens body 14 to perform a 180-degree fixed-point flip. During the flip, the precise rotation of motor 18 ensures the smooth flipping of the lens body 14 and avoids displacement or vibration, thereby maintaining the stability of the lens posture. The clamps 19 and motor 18 are connected by sliding insertion of alignment block 2 and alignment seat 21, which facilitates the replacement of clamps 19 according to the lens size and enhances the adaptability and flexibility of the device. A guide rail sub-slide 32 is slidably mounted on the guide rail sub-slide rail 3 installed at the lower end of the top plate 12. An extension plate 33 is fixed on one side of the guide rail sub-slide 32, and a vacuum pump 34 is mounted on its lower end via a bracket. The air inlet of the vacuum pump 34 is connected to the suction cup 41 via a hose 35. A cylinder 3 4 is fixed at the lower end of the guide rail sub-slide 32, and the suction cup 41 is installed at the end of its piston rod 3. When it is necessary to move or remove the lens body 14, the piston rod 3 of the cylinder 3 4 extends, so that the suction cup 41 contacts the lens surface. The vacuum pump 34 starts to pump air, and a negative pressure is formed inside the suction cup 41 through the hose 35, thereby firmly adsorbing the lens. The guide rail sub-slide 32 slides back and forth along the guide rail sub-slide rail 3, driving the suction cup 41 and the lens to move, realizing the precise placement or transfer of the lens. The anti-detachment block 31 prevents the guide rail sub-slide 32 from slipping off, ensuring that the movement process is safe and reliable. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
