Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and more specifically, to a lens gluing device for producing and processing optical lenses. Background Art

[0002] Optical lenses are key components in optical systems and are widely used in imaging, focusing, and spectroscopic fields. In the production and processing of optical lenses, lens bonding is a crucial process, the purpose of which is to accurately bond multiple lenses with specific glue to form a composite lens system with higher optical performance. The traditional lens bonding process usually relies on manual operation, including loading and unloading, positioning, gluing, and pressing of lenses. This method is not only inefficient, but also prone to damage to the lens or insufficient bonding accuracy due to operational errors, affecting the optical performance of the final product.

[0003] In order to solve the above-mentioned problem of automated production, the prior art publication number is CN114798338A, which discloses a lens gluing device for optical lens production and processing, comprising: a chassis, the chassis is circular, an operating table is arranged on the top of the chassis, and a bracket is fixedly connected to the top of the chassis; a storage tank, the storage tank is conical, a motor is fixedly connected to the top of the storage tank, a rotating rod is fixedly connected to the output end of the motor, and a water pump is fixedly connected to the top of the storage tank. When the operator of the present invention pulls the glue dispenser to dispense glue to the lens, the rubber block moves upward and separates from the inner wall of the glue dispensing hole so that the glue flows to the surface of the lens, and the ball moves upward to squeeze the elastic telescopic rod to shrink, and the elastic telescopic rod uses the movable rod to push the circular ring block to move when shrinking, and the scraper scrapes and cleans the inner wall of the glue dispenser through the movement of the circular ring block to avoid the condensation of glue caused by the entry of air when the ball is separated from the inner wall of the glue dispensing hole.

[0004] Although the above technology has achieved semi-automatic lens gluing, it still has many shortcomings. For example, the loading and unloading process of lenses still requires manual intervention, and continuous production cannot be achieved; the lens positioning accuracy is insufficient, which leads to easy deviation or tilt during the gluing process; the glue coating is uneven, which affects the gluing strength; the lamination process lacks flexible control, which easily causes lens damage.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] (1) The present invention realizes the automatic stacking, positioning and unloading functions of lenses by integrating the coordinated operation of the upper lens placement mechanism and the lower lens placement mechanism. The storage tube and the lower lens discharge tube adopt a vertical stacking design with a precise pushing structure, which can continuously supply multiple lenses and completely eliminate the manual intervention link. In particular, the lower lens discharge tube innovatively adopts a retractable and expandable limiting mechanism, which realizes the synchronous opening and closing of the retractable and expandable columns through the gear-driven gear disk linkage arc slide, which not only ensures the lens positioning accuracy, but also can meet the flexible clamping requirements of lenses of different diameters.

[0021] (2) The innovatively designed T-shaped rotating plate linkage mechanism of the present invention drives the four-way lens support block to move synchronously through a hydraulic push rod, forming a dynamic positioning platform during the lens unloading process. The semicircular cut surface design on the inner side of the lens support block and the coordinated rotation of the second T-shaped rotating plate can accurately capture the bottom layer of lenses and complete radial constraints, and cooperate with the inclined guide surface of the unloading guide plate to ensure that the lenses maintain a vertical posture during the falling process. This mechanical structure effectively solves the problem of lens deflection caused by traditional vibration plate loading and significantly improves positioning accuracy.

[0022] (3) The gluing control mechanism of the present invention adopts an elastic support system composed of a double spring group (a spring and a second spring) to form a dynamic buffer interface between the extrusion plate and the lower lens placement plate. The gear motor drives the rack slide to link the Z-shaped connecting rod, and cooperates with the mechanical amplification effect of the slider slot to convert linear motion into precise vertical pressure. When the lenses are in contact, the spring group can effectively absorb the impact kinetic energy, cooperate with the pressure sensor for real-time feedback adjustment, and realize flexible gluing pressure control, avoiding the risk of lens damage and improving gluing quality and efficiency.

[0044] When the upper and lower lenses are discharged, at this time, glue is sprayed on the top discharged lens through the two glue spray heads 214, and then the gear motor 27 is started, and the transmission gear 28 engages the expansion rack rod 29 to move, and the expansion rack rod 29 drives the expansion pull rod 210 to slide on the inner wall of the guide rod 24, and the expansion pull rod 210 drives the Z-shaped connecting rod 212 to move, and the Z-shaped connecting rod 212 moves to pull the glue spray head 214 out of the inner side of the upper lens placement mechanism 3 and the lower lens placement mechanism 4. When the Z-shaped connecting rod 212 continues to move, the Z-shaped connecting rod 212 drives the slider 213 to slide on the inner wall of the slider slide groove rod 217, and the slider 213 drives the rotating rod 215 to rotate, and the rotating rod 215 drives the pulling block 216 to move, and the pulling block 216 drives the extrusion plate 31 and the lower lens placement mechanism connecting plate 41 to move. The middle part moves, and then the lens is squeezed and glued through the squeezing plate 31 and the lower lens placement mechanism connecting plate 41. At this time, the spring 42 and the second spring 23 respectively elastically support the lower lens placement mechanism connecting plate 41 and the squeezing plate 31, so as to improve the stability during bonding and prevent the lens from being damaged due to hard bonding. When the lens is bonded, the gear motor 27 is started in reverse to reset the two Z-shaped connecting rods 212, and the spring 42 and the second spring 23 are reset to reset the squeezing plate 31 and the lower lens placement mechanism connecting plate 41, and the material picking mechanism 5 is started to pick up the bonded optical lens. This is a complete process of a bonding operation. When bonding is required again, just repeat the above steps, and bond the remaining optical lenses in the storage tube and the lower lens discharge tube according to the established operating process.

The clamping control assembly 58 is fixedly connected to the top of the slide plate 581, and the clamping control assembly 58 includes a slide plate 581, a third motor placement compartment 582 is fixedly connected to the top of the third motor placement compartment 582, a third motor 583 is fixedly connected to the top of the third motor placement compartment 582, an output end of the third motor 583 extends to the bottom of the third motor placement compartment 582 and is fixedly connected to a fourth gear 584, and the left and right sides of the inner wall of the slide plate 581 are respectively slidably connected to a clamping assembly push rod 585, wherein the inner side of the clamping assembly push rod 585 on one side is fixedly connected to a second rack rod 586, and the outer wall of the second rack rod 586 is connected to the fourth gear 584. 4, the rear sides of the two clamping assembly push rods 585 are fixedly connected with a clamping assembly 587, the clamping assembly 587 comprises a clamping assembly connecting plate 5871, the inner wall of the clamping assembly connecting plate 5871 is fixedly connected with a second hydraulic push rod 5872, the rear side of the clamping assembly connecting plate 5871 is fixedly connected with an inverted U-connecting frame 5873, the middle part of the rear side of the inverted U-connecting frame 5873 is fixedly connected with a T-shaped frame plate 5875, the left and right sides of the inverted U-connecting frame 5873 are respectively provided with connecting frame sliding grooves 5874, the rear end of the second hydraulic push rod 5872 is fixedly connected with a V-shaped rotating rod push-pull plate 5876, The left and right sides of the V-shaped rotating rod push-pull plate 5876 are respectively fixedly connected with C-shaped connecting plate connecting blocks 5877, the outer sides of the two C-shaped connecting plate connecting blocks 5877 are extended to the outer wall of the inverted U connecting frame 5873 through the connecting frame sliding groove 5874 and are both fixedly connected with C-shaped connecting blocks 5878, the rear sides of the top and bottom of the two C-shaped connecting blocks 5878 are both rotatably connected with V-shaped rotating rods 5879, the inner sides of the left and right two groups of V-shaped rotating rods 5879 are respectively rotatably connected to the left and right sides of the rear outer wall of the T-shaped frame plate 5875, and the rear sides of the left and right two groups of V-shaped rotating rods 5879 are both fixedly connected with clamping plates 5880;

[0046] When it is necessary to take the bonded optical lens, the second motor 55 is started, and the output shaft of the second motor 55 drives the third gear 56 to rotate. Since the third gear 56 is meshed with the rack rod 53, the rotation of the third gear 56 drives the moving block 57 to slide along the top of the L-shaped connecting plate 51. As the moving block 57 moves, the clamping control assembly 58 also moves until it reaches the preset material taking position.

[0047] At this time, the third motor 583 is started, and its output shaft drives the fourth gear 584 to rotate. Since the fourth gear 584 is meshed with the second rack rod 586, the rotation of the fourth gear 584 pushes the clamping assembly push rod 585 to slide along the inner wall of the slide rail plate 581. This action causes the clamping assembly 587 to gradually approach the optical lens to be taken.

[0048] When the clamping assembly 587 reaches the appropriate position, the second hydraulic push rod 5872 starts to work, pushing the V-shaped rotating rod push-pull plate 5876 to move backward. This movement is transmitted by the C-shaped connecting block 5878 and the V-shaped rotating rod 5879, so that the clamping plates 5880 on the left and right sides gradually approach and clamp the optical lens, and reversely start the third motor 583 to take it out.

[0049] At this point, the material taking mechanism 5 has completed the material taking action for the optical lens and is ready for the next step of handling or processing. The entire material taking process is precise and efficient, ensuring the stability and accuracy of the optical lens during processing.

[0050] The working principle of the present invention is as follows: before the optical lenses need to be bonded, firstly, a plurality of optical lenses are placed into the inner wall of the automatic unloading control bin 32 through the storage tube 34 and supported by the top of a plurality of lens support blocks 358, and then a corresponding number of optical lenses are placed on the inner wall of the lower lens discharge tube 43 and supported by the push plate 4311, and the motor 436 is started to drive the second gear 437 to engage the gear plate 439 to rotate, and then the plurality of arc-shaped slide grooves 4310 are provided to push the support block 435 to make the plurality of optical lenses The expansion rods 433 expand and retract on the inner wall of the slide rod 432 so that the multiple expansion columns 434 can limit the lenses placed on the inner wall of the lower lens discharge tube 43. When the optical lenses need to be bonded, the motor 436 is started in reverse to expand the multiple expansion columns 434 outward to release the restrictions on the lenses, and the hydraulic push rod 438 is started to push the push plate 4311 to the top by one position, thereby pushing the top lens to the top of the outer wall of the discharge tube body 431.

[0051] Then, the motor 436 is started to retract the multiple expansion columns 434 for clamping, and at the same time, the hydraulic push rod 353 is started to push the push rod connecting plate 352 to drive the L-shaped push-pull rod 355 to move, and the L-shaped push-pull rod 355 drives the connecting rod 356 to move, and the connecting rod 356 drives the two T-shaped rotating plates 357 to rotate, and the two T-shaped rotating plates 357 drive the two second connecting rods 359 to move, and the two second connecting rods 359 drive the two second T-shaped rotating plates 3510 to rotate, so that the two second T-shaped rotating plates 3510 and the two T-shaped rotating plates 357 drive the four lens supporting blocks 358 to rotate, so that the bottom lens inside is no longer dragged by the multiple lens supporting blocks 358, and the semicircular cut surfaces set by the two second T-shaped rotating plates 3510 and the two T-shaped rotating plates 357 make the lens fit on the inner wall to clamp the bottom lens.

[0052] When the upper and lower lenses are discharged, at this time, glue is sprayed on the top discharged lens through the two glue spray heads 214, and then the gear motor 27 is started, and the transmission gear 28 engages the expansion rack rod 29 to move, and the expansion rack rod 29 drives the expansion pull rod 210 to slide on the inner wall of the guide rod 24, and the expansion pull rod 210 drives the Z-shaped connecting rod 212 to move, and the Z-shaped connecting rod 212 moves to pull the glue spray head 214 out of the inner side of the upper lens placement mechanism 3 and the lower lens placement mechanism 4. When the Z-shaped connecting rod 212 continues to move, the Z-shaped connecting rod 212 drives the slider 213 to slide on the inner wall of the slider slide groove rod 217, and the slider 213 drives the rotating rod 215 to rotate, and the rotating rod 215 drives the pulling block 216 to move, and the pulling block 216 drives the extrusion plate 31 and the lower lens placement mechanism connecting plate 41 to move. The middle part moves, and then the lens is squeezed and glued through the squeezing plate 31 and the lower lens placement mechanism connecting plate 41. At this time, the spring 42 and the second spring 23 respectively elastically support the lower lens placement mechanism connecting plate 41 and the squeezing plate 31 to improve the stability during bonding and prevent the lens from being damaged due to hard bonding. When the lens bonding is completed, the gear motor 27 is reversely started to reset the two Z-shaped connecting rods 212, and the spring 42 and the second spring 23 are reset to reset the squeezing plate 31 and the lower lens placement mechanism connecting plate 41, and the material taking mechanism 5 is started to take the optical lens that has been bonded. This is a complete process of one bonding operation. When bonding is required again, just repeat the above steps, and bond the remaining optical lenses in the storage tube and the lower lens discharge tube according to the established operation process;

[0053] When it is necessary to take the material of the bonded optical lens, the second motor 55 is started, and the output shaft of the second motor 55 drives the third gear 56 to rotate. Since the third gear 56 is meshed with the rack rod 53, the rotation of the third gear 56 drives the moving block 57 to slide along the top of the L-shaped connecting plate 51. As the moving block 57 moves, the clamping control assembly 58 also moves until it reaches the preset material taking position. At this time, the third motor 583 is started, and its output shaft drives the fourth gear 584 to rotate. Since the fourth gear 584 is meshed with the second rack rod 586, The rotation of the fourth gear 584 will push the clamping assembly push rod 585 to slide along the inner wall of the slide plate 581. This action causes the clamping assembly 587 to gradually approach the optical lens to be taken. When the clamping assembly 587 reaches the appropriate position, the second hydraulic push rod 5872 starts to work, pushing the V-shaped rotating rod push-pull plate 5876 to move backward. This movement is transmitted through the C-shaped connecting block 5878 and the V-shaped rotating rod 5879, so that the clamping plates 5880 on the left and right sides gradually approach and clamp the completed optical lens, and reversely start the third motor 583 to take it out.
