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 in which the optical surfaces of two or more lenses are bonded to each other under the action of optical glue and cured by UV light to form a new lens:

[0003] When the lenses are bonded, 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 variety of processes for the lens bonding process. At the same time, during the kneading process, if the kneading is uneven, 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, so as to improve 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 placing jigs, and the lower placing 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 inside the upper movable frame, and a second bracket is slidably connected inside the lower movable frame. A sliding groove adapted to the sliding rail is formed on the opposite side of the first bracket and the second bracket.

[0012] Convex blocks are formed by extending the outer walls on both sides of the upper movable frame and the lower movable frame. A first lead screw is threaded through the convex blocks, and both ends of the first lead screw are connected to the inner wall of the machine shell by bearings. The first lead screw is designed with a double - thread.

[0013] The glue - applying mechanism includes a fixed plate. A plurality of vertical tubes are penetrated through the fixed plate. The bottom end of the vertical tube is threadedly connected with a glue - applying cover, and an exhaust hole is formed on the top surface of the glue - applying cover.

[0014] As a preferred technical solution:

[0015] In an optical lens gluing device as described above, one side of the machine shell is open - ended, and a through - slot is formed on the other side of the machine shell. One end of the upper conveying mechanism and the lower conveying mechanism extends out from the open - ended side, and one end of the upper movable frame and the lower movable frame passes through the through - slot.

[0016] Through the above - mentioned technical solution, the open - ended design facilitates the operator to place the upper placement jig and the lower placement jig on the upper conveying mechanism and the lower conveying mechanism. The through - slot design facilitates the conveyance of the glued upper placement jig and lower placement jig out of the machine shell.

[0017] In an optical lens gluing device as described above, the upper conveying mechanism and the lower conveying mechanism have the same structure. Both of them include a driving roller and a driven roller. Two sprockets are fixed on the driving roller and the driven roller by snap - pins. A conveying chain is sleeved on the sprocket and is matched with it. Both ends of the driven roller are connected to the inner wall of the machine shell by bearings, and both ends of the driving roller are connected to a support plate by bearings. The support plate is welded and fixed on the outer wall of the machine shell.

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

[0019] Through the above - mentioned technical solution, a motor is installed on the support plate, and the output shaft of the motor is butted against the driving roller. Then, the driving roller will rotate axially driven by the motor. The driving roller and the driven roller cooperate with each other, and the conveying chain can be driven to rotate through the sprocket. The motors on the upper conveying mechanism and the lower conveying mechanism are controlled by a synchronizer, so as to ensure that the upper conveying mechanism and the lower conveying mechanism rotate synchronously, so as to ensure that the upper placement jig and the lower placement jig are always vertically aligned during the movement process.

[0020] An optical lens gluing device as described above, a set of clamping holes adapted to the clamping posts are provided on both the upper placing fixture and the lower placing fixture, and a set of first magnet blocks are embedded on the bottom surface of one side of the upper placing fixture and the lower placing fixture.

[0021] Through the above technical solution, the clamping structure formed by the clamping posts and the clamping holes enables the upper placing fixture and the lower placing fixture to be installed and fixed on the upper conveying mechanism and the lower conveying mechanism by means of plugging and unplugging.

[0022] An optical lens gluing device as described above, a set of clamping holes adapted to the clamping posts are provided on both the upper placing fixture and the lower placing fixture, and a set of first magnet blocks are embedded on the bottom surface of one side of the upper placing fixture and the lower placing fixture.

[0023] Through the above technical solution, the clamping structure formed by the clamping posts and the clamping holes enables the upper placing fixture and the lower placing fixture to be installed and fixed on the upper conveying mechanism and the lower conveying mechanism by means of plugging and unplugging.

[0024] An optical lens gluing device as described above, a circular second limiting flange is formed by the inner wall of the second through hole on the lower placing fixture protruding, and a circular limiting boss is bonded to the surface of the lower placing fixture around the top of the second through hole.

[0025] Through the above technical solution, when the glue application cover descends and covers the lens, the bottom surface of the glue application cover will abut against the limiting boss, and the descending range of the glue application cover is limited by the limiting boss, so as to ensure that the glue application cover moves within the specified range, so that a glue layer with a specified thickness can be applied on the lens surface.

[0026] An optical lens gluing device as described above, a set of second magnet blocks are embedded on the opposite surfaces of the first bracket and the second bracket, the second magnet blocks and the first magnet blocks are 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 enables the clamping posts on the cross bar not to collide with them during movement, ensuring that the device can operate normally and stably.

[0028] An optical lens gluing device as described above, movable posts penetrate through the side wall bodies on both sides of the upper movable frame, the top ends of the movable posts are curved, a limiting piece is welded and fixed at the bottom ends of the movable posts, and a first spring is sleeved on the movable posts between the limiting piece and the bottom surface of the upper movable frame.

[0029] A sleeve ring is welded on one side of the first bracket, the top ends of the movable posts pass through the sleeve ring, and the cross section of the movable posts 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] An optical lens gluing device as described above, a second lead screw that penetrates through the lower movable frame and is connected to the lower movable frame by a bearing is provided on the lower movable frame. One end of the second lead screw passes out of the lower movable frame and is threadedly connected to the lower movable frame.

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

[0033] Through the above technical solution, the position design of the ejector rod and the collar enables the ejector rod to pass through the collar when the upper movable frame and the lower movable frame approach each other, so that the upper movable frame and the lower movable frame can move synchronously.

[0034] An optical lens gluing device as described above, the glue application mechanism further includes a cross plate fixedly welded to the inner wall of the machine shell, and a glue guiding pipe docked with the glue supply system. An electric push rod is arranged on the cross plate, and the output end of the electric push rod is fixedly connected to the top surface of the fixing plate.

[0035] One end of the glue guiding pipe extends into the machine shell and is threadedly and hermetically connected to a multi-way joint. The multi-way joint is communicated with a vertical pipe through a connecting hose. A limiting ring is sleeved at the bottom end of the vertical pipe, and a second spring is sleeved on the vertical pipe between the limiting ring and the bottom surface of the fixing plate. Both ends of the second spring are fixedly welded to the limiting ring and the fixing plate.

[0036] Through the above technical solution, a plurality of guide columns are vertically distributed on the top surface of the fixing plate, and the guide columns penetrate through the cross plate. In this way, when the electric push rod pushes the fixing plate to move vertically, the moving accuracy can be improved through the guide columns, ensuring that the glue application cover can accurately cover the lens and improving the glue application effect.

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

[0038] (1) The coordination of continuous operation and high-efficiency positioning. Through the synchronous design of the upper conveying mechanism and the lower conveying mechanism, and in cooperation with the placement fixture with the clamping post and the clamping hole, continuous conveying and precise positioning of the lens are achieved. The fixture moves synchronously with the conveying chain, avoiding the problem of frequent disassembly and assembly of traditional fixtures and significantly improving the operation efficiency. At the same time, the T-shaped sliding rail at the bottom of the fixture cooperates with the sliding groove in the fitting mechanism, further ensuring the stability of the lens during the gluing process and realizing the unity of high efficiency and precision.

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

[0040] (3)Synergy of magnetic attraction locking and dynamic adjustment. In the fitting mechanism, the design of opposite magnetic poles of the first magnet block and the second magnet block automatically locks when the fixture 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 lead screw enable the fixture to be smoothly pushed out of the machine shell after gluing, with convenient operation. The combination of this dynamic adjustment and static locking not only ensures the accuracy but also improves the flexibility of equipment operation.

[0041] (4)Modularity and scalability. Key components such as the sizing cover and the placement fixture adopt detachable and modular designs, facilitating the adaptation to different specifications of lenses and expanding the application range of the equipment. In addition, the automatic control of the bidirectional lead screw and the electric push rod further reduces the need for manual intervention, making it suitable for large-scale and high-efficiency production.

Detailed implementation manners

[0055] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

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

[0057] Please refer to Figures 1 - 6 As shown, the present invention provides a technical solution: an optical lens gluing device, including a housing 1, an upper conveying mechanism and a lower conveying mechanism provided in the housing 1, and a fitting mechanism and a glue application 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 out 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] There are multiple lower placement jigs 6 provided on the lower conveying mechanism, and multiple second through holes 10 for placing optical lenses are formed on the lower placement jig 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 by snap pins, and a conveying chain 2 that matches with them is sleeved on the sprockets. Both ends of the driven roller are connected to the inner wall of the machine housing 1 by bearings, and both ends of the driving roller are connected to the support plate 36 by bearings. The support plate 36 is welded and fixed on the outer wall of the machine housing 1.

[0061] A plurality of cross bars 3 are welded and fixed on the link plates of the two conveying chains 2, and a group of cylindrical clamping columns 4 protrude from the surface of the cross bar 3.

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

[0063] A circular first limiting flange 8 protrudes from the inner wall of the first through hole 7 on the upper placement jig 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 circular second limiting flange 11 protrudes from the inner wall of the second through hole 10 on the lower placement jig 6, and a circular limiting boss 12 is bonded to the surface of the lower placement jig 6 at the 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 lenses to be glued are sequentially placed into the first through hole 7 on the upper placement jig 5 and the second through hole 10 on the lower placement jig 6. 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, by inserting the clamping hole 13 and the clamping column 4, the upper placement jig 5 can be fixed on the cross bar 3 of the upper conveying mechanism, and the lower placement jig 6 can be fixed on the cross bar 3 of the lower conveying mechanism.

[0067] When the conveying chains 2 on the upper conveying mechanism and the lower conveying mechanism rotate, the upper placement jig 5 and the lower placement jig 6 can be driven to move through the cross bar 3. When the upper placement jig 5 moves to face downward, under the frictional force of the rubber ring 9, the lens will not fall off from the first through hole 7.

[0068] When the lower placement fixture 6 moves below the glue application mechanism, the glue application mechanism can apply glue to the surface of the lens on the lower placement fixture 6. After the glue application, when the lower placement fixture 6 and the corresponding upper placement fixture 5 move to the fitting mechanism, the fitting mechanism drives the upper placement fixture 5 and the lower placement fixture 6 to merge and approach each other, thereby completing the glue bonding operation of the two lenses.

[0069] As Figure 2 、 Figure 10 and Figure 11 shown, the glue application mechanism includes a fixed plate 30. A plurality of vertical tubes 32 penetrate through the fixed plate 30. The bottom end of the vertical tube 32 is threadedly connected with a glue application cover 34. An exhaust hole is provided on the top surface of the glue application cover 34.

[0070] The glue application mechanism further includes a cross plate 29 welded and fixed to the inner wall of the machine shell 1, and a glue guiding tube 31 docked with the glue supply system. An electric push rod is arranged on the cross plate 29. 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 glue guiding tube 31 extends into the machine shell 1 and is threadedly and sealedly connected with a multi-way joint. The multi-way joint is communicated with the vertical tube 32 through a connecting hose 35. A limiting ring 37 is sleeved on the bottom end of the vertical tube 32. A second spring 33 is sleeved on the vertical tube 32 between the limiting ring 37 and the bottom surface of the fixed plate 30. Both ends of the second spring 33 are welded and fixed to the limiting ring 37 and the fixed plate 30.

[0072] When the lower placement fixture 6 drives the lens thereon to move below the glue application mechanism, at this time, the fixed plate 30 is pushed to move vertically downward by the electric push rod. The fixed plate 30 drives the vertical tubes 32 thereon to move synchronously. After the glue application cover 34 on the vertical tube 32 contacts the limiting boss 12, the vertical tube 32 will be squeezed by the limiting boss 12. 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 glue application cover 34 is in close fit with the limiting boss 12.

[0073] At this time, the glue application cover 34 covers the lens, and a flat cavity is formed between the inner wall of the glue application cover 34 and the lens surface. At this time, the glue supply system pumps the glue into the glue guiding tube 31. The glue guiding tube 31 distributes the glue into a plurality of connecting hoses 35 through the multi-way joint. The connecting hose 35 introduces the glue into the above-mentioned formed cavity through the hollow vertical tube 32. During 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 mixing air between the glue and the lens. When the glue is filled, a uniform glue layer can be formed on the lens surface. The thickness of the glue layer can be adjusted by changing the height of the limiting ring 37.

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

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

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

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

[0078] A set of T-shaped sliding rails 14 are fixedly provided on the bottom surfaces of the upper placement fixture 5 and the lower placement fixture 6.

[0079] Sliding grooves 22 adapted to the sliding rails 14 are provided on the opposite surfaces of the first bracket 20 and the second bracket 21.

[0080] Lugs 18 are formed by extending the outer walls on both sides of the upper movable frame 16 and the lower movable frame 17. A first lead screw 19 is threaded through the lugs 18. Both ends of the first lead screw 19 are connected to the inner wall of the housing 1 by bearings, and the first lead screw 19 is designed with a double-thread.

[0081] A set of second magnet blocks 23 are embedded on the opposite surfaces of the first bracket 20 and the second bracket 21. The second magnet blocks 23 and the first magnet blocks 15 are of opposite magnetic poles. The first bracket 20, the second bracket 21, the upper movable frame 16 and the lower movable frame 17 are all in a right-angled U-shaped structure.

[0082] Moving columns 24 are penetrated through the side walls of the upper movable frame 16. The top ends of the moving columns 24 are curved. A limiting piece is fixedly welded to the bottom ends of the moving columns 24. A first spring 26 is sleeved on the moving columns 24 between the limiting piece and the bottom surface of the upper movable frame 16.

[0083] A sleeve 25 is welded to the side of the first bracket 20 that fits the moving column 24, and the top end of the moving column 24 passes through the sleeve 25.

[0084] A second lead screw 28 is penetrated through the lower movable frame 17 and is connected to the lower movable frame 17 by a bearing. One end of the second lead screw 28 passes out of the lower movable frame 17 and is threaded with the lower movable frame 17.

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

[0086] After sizing is completed, the lower placement fixture 6 and the upper placement fixture 5 located above it will move horizontally towards the bonding mechanism. At this time, the sliding rails 14 on the upper placement fixture 5 will be inserted into the sliding grooves 22 on the first bracket 20, and the sliding rails 14 on the lower placement fixture 6 will be inserted into the sliding grooves 22 on the second bracket 21.

[0087] The tops of both first lead screws 19 are connected to motors, and the two motors are controlled by a synchronizer to ensure that the first lead screws 19 can rotate synchronously. The double-thread design of the first lead screws 19 causes the first lead screws 19 to drive the upper movable frame 16 downward and the lower movable frame 17 upward when rotating clockwise through the bumps 18. That is, the upper movable frame 16 and the lower movable frame 17 can move closer to each other. At this time, the clamping holes 13 on the upper placement fixture 5 and the lower placement fixture 6 are separated from the clamping posts 4, and the upper placement fixture 5 and the lower placement fixture 6 will move synchronously with the upper movable frame 16 and the lower movable frame 17 until the lenses on the upper placement fixture 5 and the lower placement fixture 6 are combined, thus completing the bonding operation.

[0088] The first bracket 20 is a sliding structure on the upper movable frame 16. When the upper placement fixture 5 moves onto the first bracket 20, it will exert a pushing force on the first bracket 20. To prevent the first bracket 20 from shifting, a movable post 24 is provided. One end of the movable post 24 is sleeved in the collar 25, so as to limit the first bracket 20 and ensure that the upper placement fixture 5 can completely move onto the first bracket 20.

[0089] When the upper placement fixture 5 is located on the first bracket 20 and the lower placement fixture 6 is located on the second bracket 21, the second magnet block 23 and the first magnet block 15 will be in contact and generate a magnetic adsorption effect, locking the upper placement fixture 5 and the lower placement fixture 6 through magnetism. To prevent the upper placement fixture 5 and the lower placement fixture 6 from shifting during the process of moving closer to each other by the upper movable frame 16 and the lower movable frame 17, ensure that the lenses on both can be accurately aligned, guarantee the concentricity of the two lenses, and improve the bonding quality.

[0090] When it is necessary to take out the bonded lenses, a second lead screw 28 is provided. After the upper movable frame 16 and the lower movable frame 17 move closer, the upper movable frame 16 contacts the bottom end of the movable post 24 and can exert an upward squeezing force on the movable post 24, forcing the movable post 24 to move upward and compress the first spring 26. After the movable post 24 moves, its bent end will move out of the collar 25. At this time, the ejector rod 27 is inserted into the collar 25. The second lead screw 28 is also connected to a motor. Driven by the motor, the second lead screw 28 drives the second bracket 21 to move horizontally on the lower movable frame 17. Since the ejector rod 27 passes through the collar 25, the second bracket 21 and the first bracket 20 can move synchronously.

[0091] The second bracket 21 and the first bracket 20 cooperate to drive the upper placement jig 5 and the lower placement jig 6 therebetween to move 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, 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 lead screw 28 is driven by the motor to rotate reversely, 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 lead screw 19 to facilitate the next gluing operation. After separation, the movable column 24 resets 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 collar 25 again.
