Description

Technical Field

[0001] This utility model relates to the field of optical component manufacturing equipment technology, and in particular to a vacuum adsorption clamping device for a self-focusing lens. Background Technology

[0002] Self-focusing lenses are miniature optical elements that utilize the sinusoidal propagation characteristic of light in a gradient refractive index medium. They are widely used in fiber optic communication, medical imaging, lidar, and other fields. High surface precision is required, and the clamping and transport processes during production demand extremely high stability and safety. Vacuum adsorption clamping devices are specialized equipment designed to meet these requirements. Currently, self-focusing lenses, as a precision optical component, require multiple processing and transfer steps during production. In existing technologies, self-focusing lenses are mostly clamped using mechanical clamping methods, which can easily lead to scratches on the lens surface or edge breakage. Some vacuum adsorption devices lack precise positioning structures, and the lens is prone to shifting during adsorption, affecting the accuracy of subsequent processing or transfer. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a vacuum adsorption clamping device for a self-focusing lens.

[0004] This utility model is achieved using the following technical solution: a vacuum adsorption clamping device for a self-focusing lens, comprising a conveying assembly for conveying the self-focusing lens, a cross-shaped linear module at the top of the conveying assembly for assisting in the transfer of the self-focusing lens, a slide table on one side of the cross-shaped linear module, and multiple adsorption components for vacuum adsorption of the self-focusing lens on one side of the slide table, each adsorption component being equipped with an adjustment component for adjusting the position of the self-focusing lens, a movable plate fixedly mounted on the bottom side of the slide table, and an adsorption component including a vacuum column disposed on the bottom side of the movable plate, the top end of the vacuum column penetrating the movable plate and fixedly fitted with a fixing ring, the bottom end of the vacuum column being fixedly connected to a vacuum suction cup, a vacuum pump disposed on one side of the cross-shaped linear module, the output end of the vacuum pump being fixedly connected to a main pipe, and multiple branch pipes branching out from one end of the main pipe, each branch pipe having one end fixedly connected to the top end of an adjacent vacuum column.

[0005] Through the above technical solution, the negative pressure generated by the vacuum pump is transmitted to the vacuum suction cup through the main pipe, branch pipe and vacuum column to achieve non-destructive adsorption of the self-focusing lens; the cross linear module drives the slide and adsorption components to move, completing the lens transfer, and the fixing ring can enhance the connection stability between the vacuum column and the moving plate.

[0006] As a further improvement to the above solution, the adjustment component includes a limiting ring fixedly sleeved on the vacuum column, with fixed columns fixedly installed on both sides of the limiting ring, and sliding grooves opened at the ends of the two fixed columns that are far apart from each other. Pushing columns are slidably installed inside the two sliding grooves, and connecting plates are fixedly installed at one end of the two pushing columns. Adjustment plates are fixedly installed at the bottom ends of the two connecting plates.

[0007] Through the above technical solution, the adjustment plate can calibrate the position of the lens before adsorption, push the column to slide in the sliding groove, realize the movement of the adjustment plate, and adapt to the positioning requirements of lenses of different sizes.

[0008] As a further improvement to the above solution, both adjustment plates are arranged in an arc shape.

[0009] The above technical solution achieves a higher degree of fit between the arc-shaped adjustment plate and the cylindrical surface of the self-focusing lens, preventing scratches on the lens during positioning and improving positioning stability.

[0010] As a further improvement to the above solution, a limiting plate is fixedly installed at the other end of each of the two pushing columns, and a baffle with an opening shape is slidably sleeved on each of the two pushing columns. The outer side of each of the two baffles is fixedly installed with the inner wall of the opening of the adjacent sliding groove, and the two limiting plates are located inside the adjacent sliding groove.

[0011] Through the above technical solution, the limiting plate can prevent the push column from disengaging from the sliding groove, and the baffle plays a guiding role in the sliding of the push column, ensuring that the adjustment plate moves smoothly.

[0012] As a further improvement to the above solution, each of the two sliding grooves is provided with a push spring, and the two ends of the two push springs abut against the adjacent limiting plate and the inner wall of the sliding groove, respectively.

[0013] Through the above technical solution, the elastic force of the spring is transmitted to the adjustment plate through the limiting plate and the pushing column, so that the adjustment plate always has a pushing force in the direction away from the lens, which can adapt to the clamping requirements of lenses of different diameters.

[0014] As a further improvement to the above solution, each vacuum column is provided with a pushing block on both sides for pushing the connecting plate. The top of each pushing block is fixedly installed with the bottom side of the moving plate, and one side of each pushing block is inclined.

[0015] With the above technical solution, when the moving plate moves down, the inclined surface of the pushing block contacts the connecting plate, which can push the adjusting plate to move in the direction of the lens, thereby allowing the adjusting plate to adjust the position of the lens, and finally allowing the vacuum suction cup to hold the lens.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves non-destructive gripping of self-focusing lenses through a vacuum adsorption component. Combined with the elastic positioning structure of the adjustment component, it solves the problem of low positioning accuracy caused by direct suction from traditional suction cups. The push block and push spring work together to make the device adaptable to lenses of different sizes, improving its versatility. The cross-shaped linear module-driven transfer structure ensures efficient and stable transfer of lenses between processes, which helps to improve production efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Please combine Figures 1-4 This embodiment of a vacuum adsorption clamping device for a self-focusing lens includes a conveying component 1 for conveying the self-focusing lens. The top of the conveying component 1 is provided with a cross-shaped linear module 2 that can assist in the transfer of the self-focusing lens. A slide 3 is installed on one side of the cross-shaped linear module 2. A plurality of adsorption components that can vacuum adsorb the self-focusing lens are provided on one side of the slide 3. Each adsorption component is provided with an adjustment component that can adjust the position of the self-focusing lens.

[0021] A movable plate 6 is fixedly installed on the bottom side of the slide table 3. The adsorption assembly includes a vacuum column 401 disposed on the bottom side of the movable plate 6. The top end of the vacuum column 401 extends upward through the movable plate 6 and is fixedly fitted with a fixing ring 402. The bottom end of the vacuum column 401 is fixedly connected to a vacuum suction cup 403. A vacuum pump 404 is disposed on one side of the cross-shaped linear module 2. The output end of the vacuum pump 404 is fixedly connected to a main pipe 405. Multiple branch pipes 406 are distributed from one end of the main pipe 405. One end of each branch pipe 406 is fixedly connected to the top end of the adjacent vacuum column 401.

[0022] The negative pressure generated by the vacuum pump 404 is transmitted to the vacuum suction cup 403 through the main pipe 405, branch pipe 406 and vacuum column 401 to achieve non-destructive adsorption of the self-focusing lens; the cross linear module 2 drives the slide table 3 and adsorption components to move, completing the lens transfer, and the fixing ring 402 can prevent the vacuum column 401 from separating from the moving plate 6.

[0023] The adjustment assembly includes a limiting ring 501 fixedly sleeved on the vacuum column 401. Fixed columns 502 are fixedly installed on both sides of the limiting ring 501. Sliding grooves are opened at the ends of the two fixed columns 502 that are far apart. Pushing columns 503 are slidably installed inside the two sliding grooves. Connecting plates 504 are fixedly installed at one end of the two pushing columns 503. Adjusting plates 505 are fixedly installed at the bottom ends of the two connecting plates 504. The two adjusting plates 505 are both arc-shaped.

[0024] The adjustment plate 505 can calibrate the position of the lens before adsorption, and push the column 503 to slide in the sliding groove to realize the movement of the adjustment plate 505, which can adapt to the positioning requirements of lenses of different sizes.

[0025] The other end of each of the two push columns 503 is fixedly installed with a limiting plate 7. Each of the two push columns 503 is slidably fitted with a baffle 8 in the shape of an octagon. The outer side of each baffle 8 is fixedly installed with the inner wall of the opening of the adjacent sliding groove. Both limiting plates 7 are located inside the adjacent sliding groove.

[0026] The limiting plate 7 prevents the push column 503 from disengaging from the sliding groove, and the baffle 8 guides the sliding of the push column 503 to ensure that the adjustment plate 505 moves smoothly.

[0027] Both sliding grooves are equipped with push springs 9 inside, and the two ends of the two push springs 9 abut against the adjacent limiting plate 7 and the inner wall of the sliding groove, respectively.

[0028] The elastic force of the push spring 9 is transmitted to the adjustment plate 505 through the limiting plate 7 and the push column 503, so that the adjustment plate 505 always has a pushing force in the direction away from the lens, which can adapt to the clamping requirements of lenses of different diameters.

[0029] Each vacuum column 401 has a push block 10 on both sides for pushing the connecting plate 504. The top of each push block 10 is fixedly installed to the bottom side of the moving plate 6, and one side of each push block 10 is inclined.

[0030] When the moving plate 6 moves down, the inclined surface of the pushing block 10 contacts the connecting plate 504, which can push the adjusting plate 505 to move in the direction of the lens, thereby allowing the adjusting plate 505 to adjust the position of the lens, and finally allowing the vacuum suction cup 403 to hold the lens.

[0031] The implementation principle of a vacuum adsorption clamping device for a self-focusing lens in this application embodiment is as follows: when it is necessary to clamp and transfer the self-focusing lens on the conveying assembly 1, the cross linear module 2 is started first, driving the slide table 3 and the moving plate 6 to move above the lens.

[0032] After the vacuum suction cup 403 moves to directly above the lens, the cross-shaped linear module 2 descends, and the vacuum suction cup 403 will adhere to the top of the lens. The two adjustment plates 505 will also move to the bottom sides of the lens. Then, the cross-shaped linear module 2 continues to descend, and the moving plate 6 will descend. The descent of the moving plate 6 will cause the inclined surface of the pushing block 10 to contact the top of the connecting plate 504. As the moving plate 6 continues to descend, the two pushing blocks 10 will push the two adjacent connecting plates 504.

[0033] When the two connecting plates 504 are pushed, the pushing column 503 moves into the sliding groove, which compresses the pushing spring 9. At the same time, the movement of the connecting plates 504 causes the adjusting plate 505 to push the bottom of the lens, thus adjusting the position of the lens.

[0034] Once the lens is positioned correctly, the vacuum pump 404 starts, and the negative pressure generated is transmitted to the vacuum suction cup 403 through the main pipe 405, branch pipe 406 and vacuum column 401. The vacuum suction cup 403 contacts the lens surface and forms a seal, thus adsorbing and fixing the lens.

[0035] Subsequently, the cross-shaped linear module 2 drives the adsorption component to move upward, the push block 10 disengages from the connecting plate 504, the spring 9 is pushed to restore its deformation, the push column 503 is pushed to reset through the limiting plate 7, the connecting plate 504 drives the adjusting plate 505 to move outward and separate from the lens, to avoid contact with the lens and shaking that could cause the lens to fall off, and then the lens will be picked up by the vacuum suction cup 403 for transfer.

[0036] During the transfer process, the cross-shaped linear module 2 drives the slide table 3 to move and transfer the lens to the target station. After reaching the station, the cross-shaped linear module 2 descends, which in turn causes the moving plate 6 to descend, so that the connecting plate 504, together with the adjusting plate 505, clamps and limits the position of the lens. Then the vacuum pump 404 stops working, and the vacuum suction cup 403 loses its suction. At this time, the lens is completely placed on the plane, but the adjusting plate 505 is still clamping the lens.

[0037] Finally, the cross-shaped linear module 2 moves upward, taking the moving plate 6 with it. This causes the pushing block 10 to separate from the connecting plate 504, and the adjusting plate 505 to separate from the lens. The lens then stops steadily in its placement position, thus completing the entire lens transfer process. If further clamping is required, the device repeats the above actions to achieve continuous operation.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
