Description

Technical Field

[0001] This invention relates to the field of optical lens manufacturing technology, specifically to a lens bonding apparatus for optical lens manufacturing and processing. Background Technology

[0002] Cemented lenses, also known as achromatic lenses, are a type of optical lens that typically requires two individual lenses to be cemented together. They offer significantly improved performance in polychromatic imaging compared to single lenses. Achromatic lenses correct for chromatic dispersion by cementing two lenses made of different materials together. In the design and manufacturing of optical lenses, to meet requirements such as improving transmittance, eliminating chromatic aberration, and reducing the processing difficulty of composite optical glasses, it is necessary to cement two lenses with opposite R-values ​​but identical outer diameters and materials together. Therefore, lens cementing devices are required during the optical lens manufacturing process to bond the two lenses together.

[0003] In the process equipment for bonding lenses, for example, in the patent document with application number: 202110748909.5, a lens bonding device for optical lens production and processing is disclosed, and specifically, a first clamping mechanism and a second clamping mechanism are used to clamp and fix lower and upper lenses of different models before bonding.

[0004] In the above technical solution, the upper and lower lenses are directly bonded by pressing. However, the glue will condense on the lens to form glue droplets. When pressing directly, the generated air cannot be expelled in time, resulting in air bubbles in the generated lens, which affects the imaging effect of the generated lens. Summary of the Invention

[0009] A further technical improvement of the present invention is that: the moving component includes a first moving component and a second moving component, the power end of the first moving component is provided with the second moving component, the moving directions of the first moving component and the second moving component are at ninety degrees, and the first placement component is located at the output end of the second moving component.

[0010] A further technical improvement of the present invention is that: the first moving component includes a first motor, the first motor is driven and connected to a first screw, a first mounting seat is threaded on the first screw, the first mounting seat and a first support seat are slidably connected; the second moving component includes a second motor, the second motor is fixed on the first mounting seat, the second motor is driven and connected to a second screw, a second mounting seat is threaded on the second screw, the second mounting seat and the first mounting seat are slidably connected, and the second mounting seat and the first placement component are fixedly connected.

[0011] A further technical improvement of the present invention is that: the first placement component includes a mounting circular plate, a power telescopic rod is fixed on the mounting circular plate, a bottom mounting plate is fixed at the end of the power telescopic rod, a hinged connecting rod is rotatably arranged on the bottom mounting plate, the hinged connecting rod and the sliding sleeve are connected, the sliding sleeve and the sliding seat are slidably connected, the mounting circular plate and the sliding seat are fixedly connected, and a clamping plate is provided on the sliding sleeve.

[0012] A further technical improvement of the present invention is that: a second hinge seat is fixed on the bottom mounting plate, a first hinge seat is fixed on the sliding sleeve, and the two ends of the hinge connecting rod are respectively hinged to the first hinge seat and the second hinge seat.

[0013] A further technical improvement of the present invention is that: a power motor is fixed on the side of the mounting plate away from the power telescopic rod, the power motor drives and connects to the power shaft, a placement suction cup is fixed on the power shaft, and the placement suction cup is provided with a rigid suction cup opening.

[0014] A further technical improvement of the present invention is that a movable sleeve is fixed on the sliding sleeve, a movable rod is slidably arranged on the movable sleeve, and the end of the movable rod is fixedly connected to the clamping plate.

[0015] A further technical improvement of the present invention is that a limiting sliding plate is fixed on the moving rod, and a first limiting rod and a second limiting rod are fixed on the mounting plate through a limiting mounting plate, and the first limiting rod and the second limiting rod limit the limiting sliding plate respectively.

[0016] A further technical improvement of the present invention is that: an internal spring is fixed inside the movable sleeve, an internal sliding plate is fixed on the internal spring, the internal sliding plate and the movable sleeve are slidably connected, and the internal sliding plate and the movable rod are fixedly connected.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this application, the second lens is held by a first placement component, and the first lens is held by a second placement component. The first lens is then treated with adhesive by an adhesive dispensing component. Subsequently, the second placement component moves the second lens toward the first lens, so that the second lens and the first lens are connected by pushing. During this process, the second lens and the first lens are fully connected, thereby minimizing the formation of air bubbles and ensuring the quality of the generated lens.

[0019] 2. In this application, by utilizing the extension of the power telescopic rod, the bottom mounting plate is moved longitudinally, thereby causing the second hinge seat to move longitudinally. This changes the direction of the hinge telescopic rod relative to the vertical, thereby causing the first hinge seat to move. This causes the sliding sleeve to move laterally on the sliding seat, thereby adjusting the distance between the clamping plates. This causes the clamping plates to move towards each other, thereby adjusting the position of the first lens and the second lens. This ensures that the first lens and the second lens are positioned in the middle of the mounting disc, thus improving the accuracy of the position of the first lens and the second lens when they are pushed together.

[0020] 3. In this application, when the clamping plate moves, the limiting sliding plate is raised under the limiting action of the first limiting rod and the second limiting rod, controlling the internal sliding plate to slide inside the moving sleeve, so that the internal spring bears an upward pulling force, thereby causing the moving rod to adjust the height of the clamping plate, so that the height of the clamping plate can be adapted during the push-fitting process, avoiding interference problems during the push-fitting process, and ensuring the push-fitting connection of the first lens and the second lens.

[0021] 4. In this application, the moving module drives the moving base to move, thereby causing the dispensing end to move laterally, so that the dispensing end can be used to dispense glue onto the first lens. Specifically, the dispensing end emits a mist of glue, which coats the first lens. The atomized glue can reduce the formation of air bubbles.

[0022] 5. In this application, since the adhesive is easily pushed to the edge of the lens during the push-fitting process, when the lens is clamped by the clamping plate, the power motor drives the placement suction cup to rotate, which in turn drives the first lens and the second lens to rotate. At this time, the edges of the first lens and the second lens come into contact with the clamping plate, and the clamping plate is used to initially wipe away the residual adhesive to prevent the residual adhesive from affecting the surface of the first lens or the second lens.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0033] Please see Figure 1-7 As shown, the lens bonding device for optical lens manufacturing and processing includes a first moving component 1, wherein a second moving component 6 is provided at the power end of the first moving component 1, and the moving direction of the first moving component 1 and the moving direction of the second moving component 6 are at ninety degrees, thereby enabling the power plate 2 provided at the end of the first moving component 1 to move on a plane, thereby controlling the position of the power plate 2.

[0034] A first placement component 4 is mounted on the power plate 2 via a connecting support base 3, and a second placement component 5 is provided on the dispensing component. The lowest surface of the first placement component 4 and the highest surface of the second placement component 5 are on the same horizontal plane, or the heights of the first placement component 4 and the second placement component 5 are within a certain range. That is, the height of the first moving component 1 is adjustable, so that the height of the lowest end of the first placement component 4 can be adjusted to match the second placement component 5. In use, by moving the position of the first placement component 4, the first placement component 4 holding the second lens 13 moves towards the second placement component 5 holding the first lens 12, so that the second lens 13 and the first lens 12 are bonded by pushing, which can avoid the formation of air bubbles and ensure the bonding quality of the first lens 12 and the second lens 13.

[0035] Specifically, the second placement component 5 is installed on the dispensing machine 9, which is equipped with a moving module 10. The output end of the moving module 10 is laterally mounted with a moving seat 7, and the output end of the moving seat 7 is equipped with a dispensing tip 8. That is, the moving module 10 is used to drive the moving seat 7 to move laterally, and controls the dispensing tip 8 to move laterally, thereby dispensing glue onto the first lens 12 placed on the second placement component 5. Therefore, glue 11 is dripped onto the first lens 12. The glue 11 is distributed on the first lens 12 in an atomized state. Due to the atomized state, the formation of air bubbles can be reduced. At the same time, through the pushing action, the generation of air bubbles during bonding can be further reduced.

[0036] The first moving component 1 includes a first motor 101, which is located at the output end of the longitudinal telescopic rod. The first motor 101 is driven by the longitudinal telescopic rod to move longitudinally. The first motor 101 is connected to a first screw 104. A first support seat 103 is fixed at the output end of the longitudinal telescopic rod. The first support seat 103 and the first screw 104 are rotatably connected. A first mounting seat 102 is threaded onto the first screw 104. The first mounting seat 102 and the first support seat 103 are slidably connected. That is, the first motor 101 drives the first screw 104, causing the first mounting seat 102 to slide under the limiting action of the first support seat 103.

[0037] Subsequently, the second moving component 6 includes a second motor 601, which is fixedly mounted on the first mounting base 102. The first mounting base 102 is threaded with a second screw, and the second motor 601 drives and connects to the second screw. The second mounting base 602 is threaded on the second screw, and the second mounting base 602 and the first mounting base 102 are slidably connected. That is, under the action of the second motor 601, the second screw is driven, causing the second mounting base 602 to slide under the limiting action of the first mounting base 102, thereby moving the second mounting base 602.

[0038] The first placement component 4 and the second placement component 5 have the same structure, so the first placement component 4 will be used as an example below.

[0039] The first placement assembly 4 includes a mounting circular plate 422, wherein multiple sets of sliding seats 420 are fixed to the side of the mounting circular plate 422. The sliding seats 420 are in the shape of an "I" and the end of the sliding seat 420 away from the mounting circular plate 422 is fixed to a fixed point. In the first placement assembly 4, the end of the sliding seat 420 away from the mounting circular plate 422 is fixed to the connecting support 3. In the second placement assembly 5, the end of the sliding seat 420 away from the mounting circular plate 422 is fixed to the dispensing machine 9. The sliding seats 420 are slidably mounted on... A sliding sleeve 406 is provided, wherein a first hinge seat 405 and a clamping assembly are fixed on both sides of the sliding sleeve 406 respectively. A hinge connecting rod 404 is rotatably mounted on the first hinge seat 405. One end of the hinge connecting rod 404 away from the first hinge seat 405 is rotatably mounted on a second hinge seat 403. The second hinge seat 403 is fixedly mounted on a bottom mounting plate 402. The bottom mounting plate 402 is fixedly mounted on a power telescopic rod 401. The power telescopic rod 401 is mounted on a mounting circular plate 422.

[0040] Specifically, by extending the power telescopic rod 401, the bottom mounting plate 402 is moved longitudinally, thereby causing the second hinge seat 403 to move longitudinally. This changes the angle between the hinge link 404 and the vertical direction, causing the first hinge seat 405 to move the sliding sleeve 406 on the sliding seat 420. This allows the lateral clamping position of the clamping assembly to be adjusted. Since the clamping assemblies are evenly arranged on the mounting circular plate 422, a placement assembly is provided in the middle of the mounting circular plate 422 to place the second lens 13, thereby restricting the position of the second lens 13 and ensuring that the second lens 13 can fit against the first lens 12.

[0041] The placement component includes a power motor 419, which is mounted on a mounting circular plate 422. The power motor 419 drives a power shaft 418, on which a placement suction cup 416 is fixed. The placement suction cup 416 has uniformly arranged rigid suction cup openings. The power motor 419 drives the power shaft 418 to rotate, thereby driving the placement suction cup 416 to rotate, which is used to cooperate with the clamping component to work.

[0042] Specifically, the second lens 13 is placed on the placement suction cup 416. The initial adsorption of the placement suction cup 416 is used to fix the second lens 13. Then, the clamping component holds the second lens 13 in the middle position of the placement suction cup 416. The adsorption force of the placement suction cup 416 on the second lens 13 increases, thereby achieving precise fixation of the second lens 13. Then, the clamping component is removed, and the installation of the second lens 13 is completed. In actual use, the placement suction cup 416 can be rotated by the power motor 419, thereby rotating the second lens 13.

[0043] The clamping assembly includes a clamping plate 411 and a top fixing plate 407 fixed on the sliding sleeve 406. A movable sleeve 417 is fixed on the top fixing plate 407, and the end of the movable sleeve 417 is provided with the clamping plate 411. The clamping plate 411 is arc-shaped and is used to clamp and limit the arc-shaped second lens 13. The clamping plate 411 is also provided with absorbent cotton to absorb the residual adhesive that has been pushed out.

[0044] When the second lens 13 and the first lens 12 are pushed together, it is necessary to control the position of the clamping plate 411 so that the clamping plate 411 is located below the first lens 12 to avoid interference during the pushing and closing process. Therefore, an internal spring 424 is fixed inside the movable sleeve 417, and an internal sliding plate 423 is fixed on the internal spring 424. The internal sliding plate 423 is slidably connected to the movable sleeve 417. A moving rod 414 is fixed on the internal sliding plate 423, and a top seat 413 is fixed to the end of the moving rod 414. A top support rod 412 is fixed to the side of the top seat 413. The device includes a clamping plate 411 and a limiting sliding plate 415 fixed on the moving rod 414. A mounting support 421 is fixed on the mounting circular plate 422. A first limiting rod 409 and a second limiting rod 408 are fixed on the mounting support 421 via a limiting mounting plate 410. The first limiting rod 409 and the second limiting rod 408 are located on both sides of the moving rod 414. The limiting sliding plate 415 is used to slide with the first limiting rod 409 and the second limiting rod 408. The first limiting rod 409 and the second limiting rod 408 are inclined to control the height of the clamping plate 411.

[0045] Specifically, when the movable sleeve 417 moves, the limiting sliding plate 415 is raised under the limiting action of the first limiting rod 409 and the second limiting rod 408, that is, the internal sliding plate 423 slides inside the movable sleeve 417. At this time, the internal spring 424 bears an upward pulling force. At this time, the moving rod 414 drives the height of the clamping plate 411 to adjust, so that when the clamping plate 411 moves laterally, it also moves longitudinally until the clamping plate 411 reaches the height of the second lens 13 and clamps the second lens 13. After the push-and-close is completed, the clamping plate 411 can be used to clamp the second lens 13, and the power motor 419 drives the second lens 13 to rotate, adsorbing the residual adhesive pushed out on the second lens 13.

[0046] In use, the first lens 12 is placed on the second placement assembly 5, and the second lens 13 is placed on the first placement assembly 4. The first lens 12 and the second lens 13 are then attached and fixed using the placement suction cup 416. Subsequently, the extension of the power telescopic rod 401 causes the bottom mounting plate 402 to move longitudinally, which in turn causes the second hinge seat 403 to move longitudinally. This causes the hinge connecting rod 404 to change its direction relative to the vertical, thereby moving the first hinge seat 405. This causes the sliding sleeve 406 to move laterally on the sliding seat 420, adjusting the distance between the clamping plates 411 so that the clamping plates 411 move towards each other. Simultaneously, as the clamping plates 411 move, the first limiting rod 4... Under the limiting action of the first limiting rod 409 and the second limiting rod 408, the limiting sliding plate 415 is raised, that is, the internal sliding plate 423 is controlled to slide inside the moving sleeve 417. At this time, the internal spring 424 bears an upward pulling force. At this time, the moving rod 414 drives the clamping plate 411 to adjust the height, so that when the clamping plate 411 moves laterally, it moves longitudinally until the positions of the first lens 12 and the second lens 13 are adjusted respectively, so that the first lens 12 and the second lens 13 are respectively located at the center position of the placement suction cup 416. At this time, the suction force of the placement suction cup 416 increases to the maximum, and the first lens 12 and the second lens 13 are fixed.

[0047] Subsequently, the moving module 10 drives the moving base 7 to move, which in turn drives the dispensing end 8 to move laterally, thereby dispensing adhesive onto the first lens 12 using the dispensing end 8. Specifically, the dispensing end 8 emits a mist of adhesive, which coats the first lens 12. The atomized adhesive reduces the formation of air bubbles. Then, the first motor 101 moves longitudinally, and then the first motor 101 controls the rotation of the first screw 104 to control the position of the first mounting base 102. The second motor 601 drives the second screw to control the second lens 13 to move closer to the first lens 12. Then, the lowest end of the second lens 13 is made to be at the same height as the highest end of the first lens 12, and the second lens 13 and the first lens 12 are pushed together until the second lens 13 and the first lens 12 are completely overlapped.

[0048] At this time, since the glue is easily pushed to the edge of the lens during the push-fitting process, when the lens is clamped by the clamping plate 411, the power motor 419 drives the placement suction cup 416 to rotate, which in turn drives the first lens 12 and the second lens 13 to rotate. At this time, the edges of the first lens 12 and the second lens 13 come into contact with the clamping plate 411, and the clamping plate 411 is used to initially wipe away the residual glue to prevent the residual glue from affecting the surface of the first lens 12 or the second lens 13.
