Description

Technical Field

[0001] The utility model belongs to the technical field of flipping devices, in particular to a lens processing flipping device. Background Art

[0002] In optical applications, lenses usually need to be precision-machined on both sides to achieve the expected optical performance. After completing the processing on one side, the flipping device can safely and efficiently flip the lens to the other side for subsequent grinding, polishing, coating and other processes. In the prior art, a mounting plate is usually movably set on the mounting box, and a rotating column is rotatably set on the mounting plate. A clamping block is fixed on the rotating column to clamp and flip the lens. However, in this method, the clamping block is fixed and inconvenient to replace. The fixed clamping block is usually only suitable for lenses of specific sizes or shapes. When lenses of different specifications need to be processed, it cannot be flexibly adjusted, resulting in the device being unable to meet the needs of multi-variety and customized production.

[0003] For example, the utility model with announcement number CN214979893U discloses a lens flipping device for optical lens processing equipment. In the technical solution of this patent, threaded sleeves are arranged at the top and bottom of the mounting box, and mounting plates are arranged at the opposite ends of the threaded sleeves. A mounting column is rotatably arranged on the mounting plate, and a clamping block is fixedly connected to the mounting column to clamp and flip the lens. However, in this method, the clamping block is fixed and not convenient to replace. Lenses of different specifications and types may require clamping parts of different sizes, shapes or materials to provide the best clamping effect and prevent the lens from sliding or deforming during processing. Clamping parts that are inconvenient to replace may not be able to flexibly adapt to various lens size changes or design requirements of new lenses, limiting the equipment's ability to support diversified product lines.

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0025] like Figure 1 , 3 As shown, a rotating column 201 is rotatably provided at the upper end of the support plate 105, and a driving member 2 for driving the rotating column 201 to rotate is provided on the outer side wall of the support plate 105. The driving member 2 includes a support frame 305 provided on the outer side wall of the two support plates 105, and a motor 2 302 is provided at the lower end of the support frame 305. A worm 303 connected to the output end of the motor 2 302 is rotatably provided at the upper end of the support frame 305, and a worm wheel 304 meshing with the worm 303 is provided at one end of the rotating column 201 close to the support frame 305. The motor 2 302 is started to drive the worm 303 to rotate, the worm 303 drives the worm wheel 304 to rotate, and the worm wheel 304 drives the rotating column 201 to rotate, thereby driving the clamping member 301 to rotate, thereby causing the clamping member 301 to rotate. The lens is driven to rotate, thereby turning the lens over, so that the same lens can be processed on both sides in one clamping without repositioning, which significantly improves production efficiency and reduces the turnover time and potential errors between processes; the ends of the two rotating columns 201 that are close to each other are each provided with a buffer structure 306. During the lens processing process, the machine tool or equipment may generate vibration. The buffer structure 306 can isolate part of the vibration to prevent it from being directly transmitted to the lens, thereby reducing the resulting decrease in processing accuracy or deterioration of the lens surface quality. The end of the buffer mechanism away from the rotating column 201 is a sleeve 203, and a clamping member 301 is detachably provided inside the sleeve 203, and a fixing component for fixing the clamping member 301 is symmetrically provided on the sleeve 203.

[0026] like Figure 1 , 2As shown, the fixing assembly includes mounting seats 205 symmetrically arranged at the upper and lower ends of the sleeve 203, the interior of the mounting seats 205 is provided with a slide rail, the interior of the slide rail is slidably provided with a pin 206, the interior of the mounting seats 205 is provided with a spring 207, one end of the spring 207 is connected to the inner side wall of the slide rail, and the other end is connected to the rear side wall of the pin 206, a through hole is provided on the mounting seat 205, and a pull rod 208 passing through the through hole is provided on the pin 206, and a slot 209 adapted to the pin 206 is provided at one end of the clamping member 301 located inside the sleeve 203, and when the clamping member 301 needs to be replaced, the pull rod 208 is pulled up and down respectively. The pin 206 can be moved to the upper and lower ends so that the pin 206 can slide out from the slot 209 on the clamp 301, so that the clamp 301 can be disassembled and replaced. After the replacement is completed, the pull rod 208 is loosened, and the pin 206 slides into the slot 209 of the clamp 301 under the action of the spring 207, thereby fixing the clamp 301. Different types of lenses may have different diameters, thicknesses, edge profiles or special shapes. The replaceable clamp 301 can be adjusted or replaced according to the specific size and shape of the lens to be processed, ensuring that lenses of various specifications can be clamped firmly and without damage, thereby expanding the scope of application of the equipment.

[0027] Working principle: When using this device, first fix the base plate 101 on the workbench through the mounting hole 107, and then start the motor 106 to rotate the bidirectional screw 102, so that the slider 103 moves along the slide groove, and then the slider 103 drives the support plate 105 to approach each other, and further the support plate 105 drives the clamping member 301 to approach each other, so as to clamp and fix the lens. When it is necessary to turn the lens over, start the motor 2 302 to drive the worm 303 to rotate, the worm 303 drives the worm wheel 304 to rotate, the worm wheel 304 drives the rotating column 201 to rotate, and then drives the clamping member 301 to rotate, and then the clamping member 301 drives the lens to rotate, so as to turn the lens over, so that the same lens can be processed on both sides in one clamping without repositioning, which significantly improves production efficiency and reduces the turnover time and potential errors between processes.

[0028] When the clamping member 301 needs to be replaced, the pull rod 208 is pulled upward and downward respectively to move the pin 206 upward and downward so that the pin 206 can slide out of the slot 209 on the clamping member 301 to facilitate disassembly and replacement of the clamping member 301. After the replacement is completed, the pull rod 208 is released, and the pin 206 slides into the slot 209 of the clamping member 301 under the action of the spring 207, thereby fixing the clamping member 301. Different types of lenses may have different diameters, thicknesses, edge profiles or special shapes. The replaceable clamping member 301 can be adjusted or replaced according to the specific size and shape of the lens to be processed, ensuring that lenses of various specifications can be clamped firmly and without damage, thereby expanding the scope of application of the equipment.
