Description

Technical Field

[0001] This invention belongs to the field of lens bonding technology, specifically relating to a lens bonding machine. Background Technology

[0002] A lens is an optical element used to refract, reflect, or scatter light, and is usually made of transparent materials such as glass or plastic. Lenses are widely used in various optical devices such as eyeglasses, cameras, microscopes, and telescopes. Their main functions are to correct vision, focus light, or change the direction of light propagation.

[0003] Lens manufacturing involves multiple steps, including cutting, grinding, polishing, bonding, and coating. Lens bonding, in particular, involves using transparent adhesive (such as UV-curing adhesive or epoxy resin) to tightly bond multiple lenses together to form a lens assembly. After bonding, the optical surfaces of the lenses are seamlessly connected, reducing optical path loss and improving image quality. Currently, some lens bonding work is done manually. However, for lenses with specific requirements for eccentricity and flatness, manual bonding cannot accurately position the lenses or correct eccentricity, leading to problems such as inaccurate positioning and excessive eccentricity during manual bonding, which can easily reduce the quality of the bonded lenses.

[0004] Therefore, it is necessary to provide a lens bonding machine to address the aforementioned technical issues.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0036] like Figures 1 to 13 As shown, a lens bonding machine according to one embodiment of the present invention includes a base 1, a three-axis platform 2, a conveying mechanism 3, and a bonding mechanism 4. The three-axis platform 2 is mounted on the base 1. The conveying mechanism 3 is mounted on the three-axis platform 2 and is used for placing and bonding lenses. The bonding mechanism 4 includes a base plate 401, a fixture positioning mechanism 402, a gripper correction mechanism 403, and an ejection mechanism 404. The base plate 401 is mounted on the base 1. The fixture positioning mechanism 402, the gripper correction mechanism 403, and the ejection mechanism 404 are all mounted on the base plate 401. The gripper correction mechanism 403 and the ejection mechanism 404 surround the fixture positioning mechanism 402. The fixture positioning mechanism 402 is used to position the lens, the gripper correction mechanism 403 is used to correct the lens, and the ejection mechanism 404 is used to eject the bonded lens.

[0037] The three-axis platform 2 is used to mount the conveyor mechanism 3 for placing and bonding lenses. The conveyor mechanism 3 is used to place the lenses on the bonding mechanism 4 and perform the bonding operation. The fixture positioning mechanism 402 is used to carry the lenses and position them. The gripper correction mechanism 403 is used to correct the lenses, ensuring that the lenses are accurately placed in the bonding position. At the same time, the gripper correction mechanism 403 and the fixture positioning mechanism 402 work together to fix the lenses. The ejection mechanism 404 is used to eject the bonded lenses and transfer them under the action of the conveyor mechanism 3.

[0038] The conveying mechanism 3 picks up the lens and places it onto the fixture positioning mechanism 402 for placement and bonding. The gripper correction mechanism 403 pushes the lens to correct its deviation and, together with the fixture positioning mechanism 402, clamps and fixes the lens. The conveying mechanism 3 can press the upper part of the lens and complete the bonding. After the lens is bonded, the ejection mechanism 404 can eject the lens and transfer it using the conveying mechanism 3.

[0039] like Figure 1As shown, the three-axis platform 2 includes an X-axis guide rail 201, a Y-axis moving platform 202, and a Z-axis moving platform 203. The X-axis guide rail 201 is fixedly mounted on the base 1. The Y-axis moving platform 202 is mounted on the X-axis guide rail 201 and moves along the X-axis direction. The Z-axis moving platform 203 is mounted on the Y-axis moving platform 202 and moves along the Y-axis direction. The conveying mechanism 3 is mounted on the Z-axis moving platform 203 and moves along the Z-axis moving platform 203 in the Z-axis direction.

[0040] In this embodiment, the X-axis guide rail 201, the Y-axis moving platform 202, and the Z-axis moving platform 203 are all controlled by servo motors (e.g., model: MSMA5A1G, rated torque: 0.32 N·m, rated speed: 3000 rpm). Through the cooperation of the X-axis guide rail 201, the Y-axis moving platform 202, and the Z-axis moving platform 203, the position and height of the lens can be moved.

[0041] Preferably, the three-axis platform 2 used in this application is prior art, and the connections and circuit connections between the components of the X-axis guide rail 201, the Y-axis moving platform 202 and the Z-axis moving platform 203 are also prior art, and will not be described in detail here.

[0042] like Figures 2 to 4 As shown, the conveying mechanism 3 includes a mounting plate 301, a transfer mechanism 302, and a glue injection mechanism 303. The mounting plate 301 is mounted on the Z-axis moving platform 203. The transfer mechanism 302 is mounted on the mounting plate 301 and is used to transfer and press the lens. The glue injection mechanism 303 includes a first slide cylinder 3031, a mounting bracket 3032, and a glue injection tube 3033. The first slide cylinder 3031 is mounted on the mounting plate 301, the mounting bracket 3032 is mounted on the first slide cylinder 3031, and the glue injection tube 3033 is mounted on the mounting bracket 3032.

[0043] The transfer mechanism 302 uses negative pressure to pick up the lens, thereby enabling the lens to be transferred. The adhesive injection mechanism 303 is used to inject adhesive into the lens to complete the lens bonding operation.

[0044] During the lens bonding operation, the transfer mechanism 302 moves along three axes under the action of the three-axis platform 2, and first picks up the lower lens using the principle of negative pressure, transferring it to the fixture positioning mechanism 402. Then, the first slide cylinder 3031 operates, bringing the glue injection tube 3033 close to the lower lens and injecting glue onto it. The transfer mechanism 302 then picks up the upper lens under the action of the three-axis platform 2 and covers it onto the glued upper lens to complete the bonding operation.

[0045] like Figures 2 to 4As shown, the transfer mechanism 302 includes a vacuum pump mounting base 3021, a vacuum pump 3022, a vacuum fixing base 3023, a vacuum cover 3024, a suction head mounting base 3025, and a suction head 3026. The vacuum pump mounting base 3021 is mounted on the mounting plate 301. The vacuum pump 3022 is mounted on the vacuum pump mounting base 3021, and a suction head 30221 is connected to the vacuum pump 3022. The vacuum fixing base 3023 is mounted on the mounting plate 301 and is located on one side of the vacuum pump 3022. The vacuum fixing base 3023 has a suction chamber 30231, and the suction head 30221 is located inside the suction chamber 30231. The vacuum cover 3024 is mounted on the vacuum fixing base 3023 and covers the suction chamber 30231. The suction head mounting base 3025 is mounted on the vacuum fixing base 3023 and is in contact with the vacuum cover 3024. The suction head 3026 is mounted on the suction head mounting base 3025. The suction head mounting base 3025 has an air passage inside, and the side wall of the vacuum fixing base 3023 has an air hole that communicates with the air passage.

[0046] When the vacuum pump 3022 is running, it draws gas from the suction chamber 30231 through the suction head 30221, thereby creating a negative pressure in the space formed by the vacuum fixture 3023 and the vacuum cover 3024. The vacuum cover 3024 then creates a negative pressure at the port of the suction head 3026 through air holes and channels. With the assistance of the triaxial platform 2, the suction head 3026 can be used to pick up lenses, thus enabling lens transfer.

[0047] Preferably, the vacuum pump 3022 in this application is model MT3006V01-S3.

[0048] like Figures 5 to 12 As shown, the fixture positioning mechanism 402 includes a gluing platform 4021, a connecting plate 4022, a fixture 4023, and a pair of positioning posts 4024. The gluing platform 4021 is mounted on the base plate 401. The connecting plate 4022 is bolted to the end of the gluing platform 4021. The fixture 4023 is fixedly connected to the connecting plate 4022. The pair of positioning posts 4024 are integrally formed with the fixture 4023, and positioning protrusions 40241 are connected to the positioning posts 4024.

[0049] The gluing table 4021 is used to install the connecting plate 4022. The connecting plate 4022 is used to install the fixture 4023. The fixture 4023 is used to place the lens for gluing. The positioning post 4024 and the positioning protrusion 40241 are both used to position the lens.

[0050] The lenses to be glued are transferred to the fixture 4023, where the lower lens contacts the positioning post 4024 and the upper lens contacts the positioning protrusion 40241, thereby completing the positioning of the lens.

[0051] In addition, this application can adjust the flatness of the lens by using the suction head 3026 and the fixture 4023 together, so as to ensure the flatness value of the upper and lower lenses during and after bonding.

[0052] Specifically, the fixture 4023 has a through hole 4025, and the bonding table 4021 is equipped with a UV lamp 4026. After the lens is bonded, the UV lamp 4026 can pre-cure the lens through the through hole 4025 to ensure the stability of the lens transfer.

[0053] In this embodiment, the UV lamp 4026 is a commercially available product that can be purchased and used directly.

[0054] like Figures 5 to 12 As shown, the gripper correction mechanism 403 includes a support base 4031, a pneumatic finger cylinder 4032, a correction seat 4033, and a correction plate 4034. The support base 4031 is mounted on the base plate 401 and is located on one side of the gluing table 4021. The pneumatic finger cylinder 4032 is mounted on the base plate 401. The correction seat 4033 is mounted on one of the grippers of the pneumatic finger cylinder 4032, as shown. Figure 10 As shown. The correction plate 4034 is fixedly connected to the correction seat 4033 and is integrally formed with the correction seat 4033. The correction plate 4034 is connected to the correction protrusion 40341. The correction plate 4034 corresponds to the positioning post 4024, and the correction protrusion 40341 ​​corresponds to the positioning protrusion 40241.

[0055] When the pneumatic finger cylinder 4032 is running, the correction seat 4033 can move to correct the lens. The lower lens contacts the correction plate 4034, and the upper lens contacts the correction convex plate 40341. With the help of the positioning post 4024 and the positioning convex plate 40241, the lens can be fixed.

[0056] Preferably, the pneumatic finger cylinder 4032 is model MHZ2-6D.

[0057] like Figures 5 to 12 As shown, the ejection mechanism 404 includes a cylinder base 4041, a second slide cylinder 4042, an ejection base plate 4043, and an ejection plate 4044. The cylinder base 4041 is mounted on the base plate 401. The second slide cylinder 4042 is mounted on the cylinder base 4041. The ejection base plate 4043 is bolted to the second slide cylinder 4042. The ejection plate 4044 is bolted to the ejection base plate 4043.

[0058] After the lens is bonded, the second slide cylinder 4042 is activated, which causes the ejector base plate 4043 and ejector plate 4044 to move. The ejector plate 4044 can eject the lens on the fixture 4023, and with the help of the suction head 3026, the lens can be transferred.

[0059] In this embodiment, the first slide cylinder 3031 and the second slide cylinder 4042 are both of model HLQ16X10S.

[0060] The base 1 is also equipped with a placement plate 5, which has a lens placement plate 501 and a product placement plate 502. The lens placement plate 501 is used to place the lower lens and the upper lens, and the product placement plate 502 is used to place the bonded lens.

[0061] In practical use, the vacuum pump 3022 is operated, which creates a negative pressure at the port of the suction head 3026 through the vacuum shroud 3024 and the suction head mounting base 3025. With the cooperation of the X-axis guide rail 201, the Y-axis moving platform 202, and the Z-axis moving platform 203, the suction head 3026 picks up the lower lens from the lens placement plate 501 and transfers it to the fixture 4023. Then, the glue-applying mechanism 303 applies glue to the lower lens. The suction head 3026 then picks up the upper lens from the lens placement plate 501 and places it on top of the lower lens. The pneumatic finger cylinder 4032 operates, causing the alignment seat 4033 to move and align the lens. This ensures the lower lens circumference contacts the positioning post 4024 and the alignment plate 4034, while the upper lens circumference contacts the positioning protrusion 40241 and the alignment protrusion 40341. This centering and positioning of the lens prevents eccentricity and ensures consistent lens placement coordinates. Then, the suction head 3026 presses against the upper side of the upper lens. Through the cooperation of the suction head 3026 and the fixture 4023, the flatness of the lens can be adjusted, ensuring the flatness values ​​during and after bonding of the upper and lower lenses. Figure 5 and Figure 6 As shown. After the lenses are bonded, the UV lamp 4026 pre-cures the lenses through the through-hole 4025, bonding the upper and lower lenses together to ensure the stability of lens transfer. Finally, the suction head 3026 is used to transfer the bonded lenses onto the product placement plate 502.
