Description

Technical Field

[0001] The present invention relates to the technical field of optical lens processing, and in particular to an optical lens gluing device. Background Art

[0002] In the production and processing of optical lenses, the bonding process of optical lenses refers to the process of bonding the optical surfaces of two or more lenses to each other under the action of optical glue and cured by UV light to form a new lens:

[0003] When laminating lenses, the current glue application method is dispensing. In order to ensure that the glue can evenly cover the surface of the guide lens, the glue needs to be kneaded before the lens is bonded. This results in a complex lens bonding process. At the same time, if the kneading is uneven during the glueing process, bubbles may appear in the glue layer, which in turn affects the optical performance of the lens after bonding.

[0004] At the same time, in order to improve the bonding accuracy, the current gluing equipment usually uses a clamp to clamp and position the two lenses to ensure the concentricity of the two lenses, and then merge and bond the two lenses. However, the use of the clamp requires frequent disassembly and assembly of the lenses, resulting in a long interval between two operations, low operating efficiency, and inability to achieve continuous operation.

[0005] In summary, existing gluing equipment has certain defects. Therefore, there is an urgent need for a new type of optical lens gluing equipment that can achieve automatic and uniform application of glue, precise positioning of lenses, and continuous operation, thereby improving gluing efficiency and product consistency. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0007] Therefore, the object of the present invention is to provide an optical lens gluing device, including a housing, an upper conveying mechanism and a lower conveying mechanism arranged in the housing, and a bonding mechanism and a gluing mechanism located in the housing.

[0008] The upper conveying mechanism is provided with a plurality of upper placement jigs, and the upper placement jigs are provided with a plurality of first through holes for placing optical lenses.

[0009] The lower conveying mechanism is provided with a plurality of lower placement jigs, and the lower placement jigs are provided with a plurality of second through holes for placing optical lenses.

[0010] A set of T-shaped sliding rails are fixed on the bottom surfaces of the upper placement jig and the lower placement jig.

[0011] The fitting mechanism includes an upper movable frame and a lower movable frame, a first bracket is slidably connected to the upper movable frame, and a second bracket is slidably connected to the lower movable frame, and a sliding groove adapted to the sliding rail is provided on the opposite side of the first bracket and the second bracket.

[0012] The outer walls of both sides of the upper movable frame and the lower movable frame extend to form protrusions, and the protrusions are penetrated by a first screw rod threadedly connected thereto. Both ends of the first screw rod are connected to bearings on the inner wall of the casing, and the first screw rod is a bidirectional thread design.

[0013] The glue applying mechanism comprises a fixing plate, a plurality of vertical pipes are passed through the fixing plate, the bottom ends of the vertical pipes are threadedly connected to glue applying covers, and the top surface of the glue applying cover is provided with exhaust holes.

[0014] As the preferred technical solution:

[0015] As described above, in an optical lens gluing device, one side of the casing is open, and a through slot is provided on the other side of the casing. One end of the upper conveying mechanism and the lower conveying mechanism extend from the open end, and one end of the upper movable frame and the lower movable frame pass through the through slot.

[0016] Through the above technical solution, the open design makes it easy for the operator to place the upper placement jig and the lower placement jig on the upper conveying mechanism and the lower conveying mechanism, and the through groove design makes it easy to convey the glued upper placement jig and the lower placement jig out of the casing.

[0017] As described above, in an optical lens gluing device, the upper conveying mechanism and the lower conveying mechanism have the same structure, and both include a driving roller and a driven roller. The driving roller and the driven roller are both fixed with two sprockets by pins, and the sprockets are covered with a conveying chain that matches them. The two ends of the driven roller are connected to the bearings on the inner wall of the casing, and the two ends of the driving roller are connected to the bearings of the support plate, and the support plate is welded and fixed to the outer wall of the casing.

[0018] A plurality of cross bars are welded and fixed to the chain plates on the two conveying chains, and a group of cylindrical clamping columns are protruded from the surfaces of the cross bars.

[0019] Through the above technical solution, a motor is installed on the support plate, and the motor output shaft is connected to the active roller, and then the active roller will rotate axially under the drive of the motor. The active roller and the driven roller cooperate with each other, and the conveyor chain can be driven to rotate through the sprocket. The motors on the upper conveying mechanism and the lower conveying mechanism are controlled by the synchronizer, so as to ensure that the upper conveying mechanism and the lower conveying mechanism rotate synchronously, thereby ensuring that the upper placement jig and the lower placement jig are always aligned up and down during the movement.

[0020] In the optical lens gluing device as described above, the upper placement jig and the lower placement jig are both provided with a group of clamping holes adapted to the clamping columns, and the bottom surfaces of one side of the upper placement jig and the lower placement jig are both inlaid with a group of first magnet blocks.

[0021] Through the above technical solution, the clamping structure formed by the clamping column and the clamping hole enables the upper placement jig and the lower placement jig to be installed and fixed on the upper conveying mechanism and the lower conveying mechanism by plugging and pulling.

[0022] In the optical lens gluing device as described above, the upper placement jig and the lower placement jig are both provided with a group of clamping holes adapted to the clamping columns, and the bottom surfaces of one side of the upper placement jig and the lower placement jig are both inlaid with a group of first magnet blocks.

[0023] Through the above technical solution, the clamping structure formed by the clamping column and the clamping hole enables the upper placement jig and the lower placement jig to be installed and fixed on the upper conveying mechanism and the lower conveying mechanism by plugging and pulling.

[0024] In the optical lens gluing device as described above, the inner wall of the second through hole on the lower placement jig protrudes to form a second annular limiting flange, and the surface of the lower placement jig at the outer periphery of the top end of the second through hole is bonded with an annular limiting boss.

[0025] Through the above technical solution, when the glue cover is lowered and covered on the lens, the bottom surface of the glue cover will abut against the limiting boss, and the limiting boss will limit the downward range of the glue cover, thereby ensuring that the glue cover moves to the specified range, so that a layer of glue of specified thickness can be applied on the surface of the lens.

[0026] As described above, in an optical lens gluing device, a group of second magnet blocks are embedded on the opposite side of the first bracket and the second bracket, the second magnet block and the first magnet block have opposite magnetic poles, and the first bracket, the second bracket, the upper movable frame and the lower movable frame are all right-angled U-shaped structures.

[0027] Through the above technical solution, the shape design of the first bracket, the second bracket, the upper movable frame and the lower movable frame ensures that the clamping columns on the crossbar will not collide with them when they move, ensuring that the equipment can operate normally and stably.

[0028] As described above, an optical lens gluing device has movable columns running through the two side walls of the upper movable frame, the top of the movable column is curved, a limiting plate is welded and fixed to the bottom of the movable column, and a first spring is sleeved on the movable column between the limiting plate and the bottom surface of the upper movable frame.

[0029] A collar is welded on one side of the first bracket, and the top end of the movable column passes through the collar. The cross section of the movable column is a square structure.

[0030] Through the above technical solution, the shape design of the movable column enables the movable column to only move vertically on the upper movable frame and cannot rotate itself, ensuring that the position of the movable column will not change and improving the limiting accuracy of the first bracket.

[0031] In the optical lens bonding device described above, the lower movable frame is provided with a second screw connected to its bearing, one end of the second screw passes through the lower movable frame and is threadedly connected to the lower movable frame.

[0032] A group of push rods are welded and fixed to the outer wall of one side of the lower movable frame, and the push rods and the collar are coaxial.

[0033] Through the above technical solution, the position design of the push rod and the collar allows the push rod to pass through the collar when the upper movable frame and the lower movable frame move closer to each other, thereby allowing the upper movable frame and the lower movable frame to move synchronously.

[0034] As described above, in an optical lens gluing device, the gluing mechanism also includes a horizontal plate welded and fixed to the inner wall of the casing, and a glue guide tube connected to the glue supply system. An electric push rod is provided on the horizontal plate, and the output end of the electric push rod is fixedly connected to the top surface of the fixed plate.

[0035] One end of the rubber guide tube extends into the casing and is threaded and sealed to a multi-way joint. The multi-way joint is connected to the vertical pipe through a connecting hose. A limiting ring is provided at the bottom end of the vertical pipe. A second spring is provided on the vertical pipe between the limiting ring and the bottom surface of the fixed plate. Both ends of the second spring are welded and fixed to the limiting ring and the fixed plate.

[0036] Through the above technical solution, multiple guide columns are vertically distributed on the top surface of the fixed plate, and the guide columns pass through the horizontal plate. In this way, the electric push rod pushes the fixed plate to move vertically. The guide columns can improve the movement accuracy, ensure that the glue cover can be accurately covered on the lens, and improve the glue effect.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] (1) The synergy between continuous operation and efficient positioning is achieved through the synchronous design of the upper and lower conveying mechanisms, in conjunction with a placement fixture with a clamping column and a clamping hole, to achieve continuous conveying and precise positioning of the lens. The fixture moves synchronously with the conveyor chain, avoiding the problem of frequent disassembly and assembly of traditional fixtures, and significantly improving operation efficiency. At the same time, the T-shaped sliding rail at the bottom of the fixture cooperates with the sliding groove in the bonding mechanism to further ensure the stability of the lens during the bonding process, achieving the unity of high efficiency and precision.

[0039] (2) Integrated design of gluing and exhaust. The gluing mechanism uses a gluing cover and a limiting boss to form a closed cavity on the lens surface. When the glue is injected through the vertical pipe, the exhaust hole can simultaneously exhaust the air, avoiding the generation of bubbles in the glue layer. The detachable design of the gluing cover is suitable for different lens types (such as flat or curved surfaces), and the elastic support of the second spring ensures a close fit between the gluing cover and the lens, thereby achieving a uniform and controllable thickness of the glue layer. This design not only simplifies the traditional gluing and kneading process, but also significantly improves the gluing quality.

[0040] (3) The synergistic effect of magnetic locking and dynamic adjustment. In the bonding mechanism, the design of the opposite poles of the first and second magnet blocks automatically locks the fixture when it moves to the bracket, preventing displacement during the gluing process and ensuring the concentricity of the lens. At the same time, the limiting structure of the movable column and the collar, and the linkage design of the ejector rod and the second screw rod enable the fixture to be smoothly pushed out of the casing after gluing, making operation convenient. This combination of dynamic adjustment and static locking not only ensures accuracy but also improves the flexibility of equipment operation.

[0041] (4) Modularity and scalability: Key components such as the sizing cover and placement fixture are detachable and modular, making it easy to adapt to lenses of different specifications and expanding the scope of application of the equipment. In addition, the automated control of the bidirectional threaded screw and electric push rod further reduces the need for manual intervention, making it suitable for large-scale and efficient production.

DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0057] See also Figures 1-6 As shown, the present invention provides a technical solution: an optical lens gluing device, comprising a housing 1, and an upper conveying mechanism and a lower conveying mechanism arranged in the housing 1, as well as a bonding mechanism and a gluing mechanism located in the housing 1, one side of the housing 1 is open, and one end of the upper conveying mechanism and the lower conveying mechanism extends from the open end.

[0058] A plurality of upper placement jigs 5 are provided on the upper conveying mechanism, and a plurality of first through holes 7 for placing optical lenses are opened on the upper placement jigs 5.

[0059] A plurality of lower placement jigs 6 are provided on the lower conveying mechanism, and a plurality of second through holes 10 for placing optical lenses are opened on the lower placement jigs 6.

[0060] The upper conveying mechanism and the lower conveying mechanism have the same structure. Both include a driving roller and a driven roller. Two sprockets are fixed on the driving roller and the driven roller with a pin. The sprockets are covered with a conveying chain 2 that matches them. Both ends of the driven roller are connected to the bearings on the inner wall of the casing 1, and both ends of the driving roller are connected to the bearings of the support plate 36. The support plate 36 is welded and fixed to the outer wall of the casing 1.

[0061] A plurality of cross bars 3 are welded and fixed to the chain plates on the two conveyor chains 2 , and a group of cylindrical clamping columns 4 are protruded from the surface of the cross bars 3 .

[0062] A group of clamping holes 13 adapted to the clamping columns 4 are provided on the upper placement jig 5 and the lower placement jig 6 , and a group of first magnet blocks 15 are embedded on the bottom surface of one side of the upper placement jig 5 and the lower placement jig 6 .

[0063] A first ring-shaped limiting flange 8 is protruded from the inner wall of the first through hole 7 on the upper placement fixture 5 , and a rubber ring 9 is bonded to the inner wall of the first through hole 7 above the top surface of the first limiting flange 8 .

[0064] A second annular limiting flange 11 is protruded from the inner wall of the second through hole 10 on the lower placement fixture 6 , and an annular limiting boss 12 is bonded to the surface of the lower placement fixture 6 at the outer periphery of the top end of the second through hole 10 .

[0065] During operation, the corresponding jig can be selected according to the size of the lens, and then the lens to be glued can be placed in the first through hole 7 on the upper jig 5 and the second through hole 10 on the lower jig 6 in turn. The first limiting flange 8 can support the lens in the first through hole 7, and the second limiting flange 11 can support the lens in the second through hole 10.

[0066] Then, the upper placement jig 5 can be fixed to the cross bar 3 on the upper conveying mechanism by plugging the clamping hole 13 with the clamping column 4 , and the lower placement jig 6 can be fixed to the cross bar 3 on the lower conveying mechanism.

[0067] When the conveying chains 2 on the upper conveying mechanism and the lower conveying mechanism rotate, the upper placing jig 5 and the lower placing jig 6 can be driven to move through the cross bar 3. When the upper placing jig 5 moves to face down, the lens will not fall out of the first through hole 7 due to the friction force of the rubber ring 9.

[0068] When the lower placement jig 6 moves to the bottom of the gluing mechanism, the gluing mechanism can apply glue to the surface of the lens on the lower placement jig 6. After gluing, when the lower placement jig 6 and the corresponding upper placement jig 5 move to the bonding mechanism, the bonding mechanism drives the upper placement jig 5 and the lower placement jig 6 to merge and move closer, thereby completing the gluing operation of the two lenses.

[0069] like Figure 2 、 Figure 10 and Figure 11 As shown, the glue applying mechanism includes a fixed plate 30 , a plurality of vertical pipes 32 pass through the fixed plate 30 , the bottom ends of the vertical pipes 32 are threadedly connected to glue applying covers 34 , and the top surface of the glue applying cover 34 is provided with exhaust holes.

[0070] The glue applying mechanism also includes a horizontal plate 29 welded to the inner wall of the casing 1 and a glue guide tube 31 connected to the glue supply system. An electric push rod is provided on the horizontal plate 29, and the output end of the electric push rod is fixedly connected to the top surface of the fixed plate 30.

[0071] One end of the rubber guide tube 31 extends into the casing 1 and is threaded and sealed to a multi-channel joint. The multi-channel joint is connected to the vertical pipe 32 through a connecting hose 35. A limiting ring 37 is provided at the bottom end of the vertical pipe 32. A second spring 33 is provided on the vertical pipe 32 between the limiting ring 37 and the bottom surface of the fixing plate 30. Both ends of the second spring 33 are welded to the limiting ring 37 and the fixing plate 30.

[0072] When the lower placement jig 6 drives the lens on it to move to the bottom of the gluing mechanism, the electric push rod pushes the fixing plate 30 to move vertically downward, and the fixing plate 30 drives the vertical tube 32 on it to move synchronously. After the gluing cover 34 on the vertical tube 32 contacts the limiting boss 12, the vertical tube 32 will be squeezed by the limiting boss 12, and the vertical tube 32 will move upward and compress the second spring 33 through the limiting ring 37. Under the action of the elastic potential energy of the second spring 33, it is ensured that the gluing cover 34 is tightly fitted with the limiting boss 12.

[0073] At this time, the glue cover 34 is covered on the lens, and the inner wall of the glue cover 34 and the surface of the lens form a flat cavity. At this time, the glue supply system pumps glue into the glue guide tube 31, and the glue guide tube 31 diverts the glue to multiple connecting hoses 35 through a multi-channel joint. The connecting hose 35 guides the glue into the above-formed cavity through the hollow vertical tube 32. In the process of filling the cavity with glue, the air in the cavity will be squeezed out through the exhaust hole, so as to avoid air mixing between the glue and the lens. When the glue is filled, a uniform glue layer can be formed on the surface of the lens. The thickness of the glue layer can be adjusted by changing the height of the limit ring 37.

[0074] After the glue application is completed, the electric push rod drives the fixing plate 30 to move vertically upward to reset. At this time, under the elastic force of the second spring 33, the vertical pipe 32 will also reset.

[0075] When it is necessary to glue different types of lenses, such as flat lenses and curved lenses, since the glue cover 34 on the vertical tube 32 is a detachable structure, it is only necessary to replace the glue cover 34 corresponding to the shape of the lens.

[0076] like Figure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown, the laminating mechanism includes an upper movable frame 16 and a lower movable frame 17 . A first bracket 20 is slidably connected to the upper movable frame 16 , and a second bracket 21 is slidably connected to the lower movable frame 17 .

[0077] A through slot is formed on the other side of the housing 1 , and one end of the upper movable frame 16 and the lower movable frame 17 pass through the through slot.

[0078] A set of T-shaped sliding rails 14 are fixed to the bottom surfaces of the upper placement jig 5 and the lower placement jig 6 .

[0079] A sliding groove 22 adapted to the sliding rail 14 is formed on one side opposite to the first bracket 20 and the second bracket 21 .

[0080] The outer walls of both sides of the upper movable frame 16 and the lower movable frame 17 extend to form a protrusion 18, and a first screw rod 19 threadedly connected to the protrusion 18 passes through the protrusion 18. Both ends of the first screw rod 19 are connected to the bearings on the inner wall of the casing 1. The first screw rod 19 is a two-way thread design.

[0081] A group of second magnet blocks 23 are embedded on the opposite side of the first bracket 20 and the second bracket 21. The second magnet block 23 and the first magnet block 15 have opposite poles. The first bracket 20, the second bracket 21, the upper movable frame 16 and the lower movable frame 17 are all right-angled U-shaped structures.

[0082] A movable column 24 is passed through the two side walls of the upper movable frame 16. The top of the movable column 24 is curved, and a limit plate is welded and fixed to the bottom of the movable column 24. A first spring 26 is sleeved on the movable column 24 between the limit plate and the bottom surface of the upper movable frame 16.

[0083] A collar 25 is welded to one side of the first bracket 20 that contacts the movable column 24 , and the top end of the movable column 24 passes through the collar 25 .

[0084] A second screw rod 28 connected to a bearing of the lower movable frame 17 passes through the lower movable frame 17 . One end of the second screw rod 28 passes through the lower movable frame 17 and is threadedly connected to the lower movable frame 17 .

[0085] A set of push rods 27 are welded and fixed to the outer wall of one side of the second bracket 21 . The push rods 27 and the collar 25 are coaxial.

[0086] After the gluing is completed, the lower placing jig 6 and the upper placing jig 5 located above it will move horizontally toward the bonding mechanism. At this time, the sliding rail 14 on the upper placing jig 5 will be inserted into the sliding groove 22 on the first bracket 20, and the sliding rail 14 on the lower placing jig 6 will be inserted into the sliding groove 22 on the second bracket 21.

[0087] The top ends of the two first screw rods 19 are connected to motors, and the two motors are controlled by synchronizers to ensure that the first screw rods 19 can rotate synchronously. The double-thread design of the first screw rod 19 allows the first screw rod 19 to rotate clockwise. The upper movable frame 16 can be driven downward through the protrusion 18, and the lower movable frame 17 can be driven upward, that is, the upper movable frame 16 and the lower movable frame 17 can move close to each other. At this time, the clamping holes 13 on the upper placing jig 5 and the lower placing jig 6 are separated from the clamping columns 4, and the upper placing jig 5 and the lower placing jig 6 will move synchronously with the upper movable frame 16 and the lower movable frame 17 until the lenses on the upper placing jig 5 and the lower placing jig 6 are merged, thereby completing the bonding operation.

[0088] The first bracket 20 is a sliding structure on the upper movable frame 16. When the upper placement jig 5 moves onto the first bracket 20, a pushing force is applied to the first bracket 20. In order to prevent the first bracket 20 from shifting, a movable column 24 is provided. One end of the movable column 24 is sleeved in the ring 25, so that the first bracket 20 can be limited, thereby ensuring that the upper placement jig 5 can be completely moved onto the first bracket 20.

[0089] When the upper placement jig 5 is located on the first bracket 20, and the lower placement jig 6 is located on the second bracket 21, the second magnet block 23 and the first magnet block 15 will fit together, thereby generating a magnetic adsorption effect. The upper placement jig 5 and the lower placement jig 6 are locked by magnetic force to prevent the upper placement jig 5 and the lower placement jig 6 from being displaced when the upper movable frame 16 and the lower movable frame 17 move towards each other, ensuring that the lenses on the two can be accurately aligned, ensuring the concentricity of the two lenses, and improving the gluing quality.

[0090] When the glued lens needs to be taken out, a second screw rod 28 is provided. After the upper movable frame 16 and the lower movable frame 17 are brought close to each other, the upper movable frame 16 contacts the bottom end of the movable column 24 and can apply an upward squeezing force to the movable column 24, thereby forcing the movable column 24 to move upward and compress the first spring 26. After the movable column 24 moves, its bent end will move out of the ring 25. At this time, the top rod 27 is inserted into the ring 25. The second screw rod 28 is also connected to a motor. Driven by the motor, the second screw rod 28 drives the second bracket 21 to move horizontally on the lower movable frame 17. Since the top rod 27 passes through the ring 25, the second bracket 21 and the first bracket 20 can move synchronously.

[0091] The second bracket 21 cooperates with the first bracket 20 to drive the upper placement jig 5 and the lower placement jig 6 between the two to be moved out of the casing 1 through the through slot. At this time, the operator pulls out the upper placement jig 5 and the lower placement jig 6 from the second bracket 21 and the first bracket 20, and then separates the upper placement jig 5 and the lower placement jig 6, and takes out the glued lens from the first through hole 7.

[0092] Finally, the second screw rod 28 is driven by the motor to rotate in the opposite direction, thereby driving the second bracket 21 and the first bracket 20 to reset. Then, the upper movable frame 16 and the lower movable frame 17 are separated and reset under the drive of the first screw rod 19 to facilitate the next gluing operation. After separation, the movable column 24 is reset under the elastic force of the first spring 25. At this time, the bent end of the movable column 24 will be inserted into the ring 25 again.
