[0031] Understandably, referring to Figures 1 to 4The lens bonding device of this utility model includes a platform 100, a feeding mechanism 200, a dispensing mechanism 300, and an adjustment mechanism 400. The platform 100 is used to receive lenses 500. The feeding mechanism 200 includes a material tray 210, a suction pen 220, and a first driving member 230. The material tray 210 is used to store lenses 500, the suction pen 220 is used to pick up lenses 500, and the first driving member 230 is used to drive the suction pen 220 to move between the material tray 210 and the platform 100. The dispensing mechanism 300 includes a dispensing assembly 310, a detection sensor 320, and a controller. The glue dispensing assembly 310 is used to dispense glue to the lens 500, and the detection sensor 320 is used to detect the thickness of the dispensed glue. Both the glue dispensing assembly 310 and the detection sensor 320 are electrically connected to the controller. The adjustment mechanism 400 includes a moving assembly 410 and an adjusting plate 420. The moving assembly 410 includes a plurality of second driving members 411, which are connected in sequence and whose driving directions are perpendicular to each other. The adjusting plate 420 is connected to the ends of the plurality of second driving members 411 so that the adjusting plate 420 can drive the lens 500 to move.

[0032] Lens 500 is stored on tray 210. The first driving component 230 drives the suction pen 220 to move between tray 210 and table 100, so that the suction pen 220 can pick up lens 500 and transfer it from tray 210 to table 100. Then, glue dispensing component 310 outputs glue to lens 500. By setting glue dispensing component 310 and detection sensor 320 to be electrically connected to controller, the detection sensor 320 can detect the thickness of the output glue, so that the glue output amount of glue dispensing component 310 can be controlled by controller to make glue output accurate and stable. Then, the first driving component 230 drives suction pen 220 to pick up another lens 500 from tray 210 and place it on table 100, so that the two lenses 500 can be connected together by glue. In addition, multiple second driving components 411 can drive the adjustment plate 420 to move, so that the adjustment plate 420 can move the lens 500, thereby adjusting the position of the lens 500 on the stage, so that the optical centers of the two lenses 500 can be aligned, replacing manual adjustment, improving the connection accuracy of the lens 500, and helping to improve the production efficiency and quality of the lens.

[0033] It should be noted that, referring to Figure 2 and Figure 4The lens 500 includes a prism 510 and a lens 520, which are connected by adhesive. The number of material trays 210 can be set to two, with the two trays 210 storing the prism 510 and the lens 520 respectively. The suction pen 220 is driven by the first driving member 230 to move, so that the suction pen 220 can sequentially transport the prism 510 and the lens 520 onto the storage table 100, so that the prism 510 and the lens 520 can be stacked on the storage table 100. Adhesive is output to the lens 500 through the adhesive dispensing component 310, so that the prism 510 and the lens 520 can be connected together by adhesive, thereby replacing manual assembly and improving the production efficiency and quality of the lens.

[0034] The first driving component 230 and the second driving component 411 can both be robotic arms, electric cylinders, pneumatic cylinders, electric actuators, linear slide modules, etc.; the detection sensor 320 can be an infrared sensor, an ultrasonic sensor, etc.; the controller can be a microcontroller, a programmable logic controller, an industrial computer, etc., and is not limited here.

[0035] Understandably, referring to Figure 2 The first driving component 230 includes a first moving part 231 and a second moving part 232. The second moving part 232 is connected to the movable end of the first moving part 231, and the suction pen 220 is connected to the movable end of the second moving part. The driving directions of the first moving part 231 and the second moving part 232 are perpendicular to each other. The first driving component 230 includes a first moving part 231 and a second moving part 232. By setting the driving direction of the first moving part 231 and the driving direction of the second moving part 232 to be perpendicular to each other, the first moving part 231 and the second moving part 232 can cooperate to drive the suction pen 220 to move within the vertical plane 521. This allows the suction pen 220 to transport materials between the material tray 210 and the table 100, achieving automatic feeding of the lens 500, replacing manual lens assembly, and improving production efficiency.

[0036] The first moving component 231 drives the second moving component 232 and the suction pen 220 to move synchronously in the horizontal direction, and the second moving component 232 drives the suction pen 220 to move in the vertical direction, so that the first moving component 231 and the second moving component 232 cooperate to drive the suction pen 220 to move in the vertical plane 521, thereby automatically transporting the lens 500 between the material tray 210 and the table 100, improving production efficiency.

[0037] It should be noted that the first moving part 231 and the second moving part 232 can both be linear cylinders, electric actuators, linear slide modules, etc., and are not limited here.

[0038] Specifically, refer to Figure 2 and Figure 3The number of second driving components 411 is set to two, which are connected sequentially. The first ends of the two second driving components 411 are connected to the movable end of the first moving component 231, and the driving directions of the first moving component 231 and the two second driving components 411 are perpendicular to each other. The cooperation between the first moving component 231 and the two second driving components 411 enables the adjusting plate 420 to move within the spatial coordinate system, allowing for flexible positioning of the adjusting plate 420 and facilitating the movement of the lens 500. This reduces the number of driving sources, making the lens bonding device more compact and lowering manufacturing costs.

[0039] Specifically, refer to Figure 1 and Figure 2 The tray 210 is connected to a third moving component 211, which drives the tray 210 to move. The driving direction of the third moving component 211 is perpendicular to the driving directions of the first moving component 231 and the second moving component 232. By setting the third moving component 211 to drive the tray 210 to move, and by ensuring that the driving direction of the third moving component 211 is perpendicular to the driving directions of the first moving component 231 and the second moving component 232, the positional flexibility of the tray 210 can be enhanced. This allows the lens 500 on the tray 210 to automatically align with the suction pen 220, thereby reducing the travel distance of the suction pen 220, facilitating the loading of the lens 500, shortening the production cycle, and improving production efficiency.

[0040] In addition, by setting the third moving part 211, the layout of the first driving part 230 can be optimized, so that the material tray 210 can be adapted to the movement direction of the suction pen 220, which can reduce the driving source of the suction pen 220, making the whole device more compact and efficient, and helping to improve production efficiency.

[0041] It should be noted that the third moving part 211 can be a cylinder, an electric cylinder, an electric actuator, a linear slide module, etc., and is not limited here.

[0042] Understandably, referring to Figure 2 The feeding mechanism 200 also includes a first vision module 240, which is used to detect the position of the lens 500. Both the first vision module 240 and the first drive unit 230 are electrically connected to the controller. The first vision module 240 is positioned above the material tray 210, and both the first vision module 240 and the first drive unit 230 are electrically connected to the controller. By setting the first vision module 240, the position of the lens 500 can be accurately detected, enabling the first drive unit 230 to drive the suction pen 220 to move accurately. This facilitates the suction pen 220 in picking up the lens 500 from the material tray 210, improving the feeding stability of the lens 500, preventing positional deviations of the suction pen 220 from damaging the lens 500, and improving production stability.

[0043] Specifically, refer to Figure 2 The adjustment mechanism 400 also includes a rotating component 430, which is connected between the first driving component 230 and the suction pen 220. The rotating component 430 drives the suction pen 220 to rotate and is electrically connected to the controller. The rotating component 430 is connected to the movable end of the first driving component 230, and the suction pen 220 is connected to the movable end of the rotating component 430. The rotating component 430 can drive the suction pen 220 to rotate, so that the suction pen 220 can adjust the placement angle of the lens 500 according to the position detected by the first vision module 240 during the handling of the lens 500. This ensures accurate placement of the lens 500, allows multiple lenses 500 to be accurately stacked together, improves the bonding quality of the lens 500, and enhances the adjustment flexibility of the lens 500, thus contributing to improved bonding quality.

[0044] It should be noted that, referring to Figure 4 The lens 520 has symmetrically arranged planes 521 on both sides, and the two planes 521 need to be aligned with the two ends of the prism 510. The first vision module 240 is arranged above the material tray 210. The first vision module 240 can detect the placement angle of the lens 520 in the material tray 210. After the first driving member 230 drives the suction pen 220 to pick up the lens 520, the rotating member 430 can drive the suction pen 220 to rotate to adjust the placement angle of the lens 520, so that the lens 520 can be aligned with the prism 510, thereby improving the positional accuracy of the lens 520.

[0045] The rotating component 430 can be an electric motor, a pneumatic motor, etc., and is not limited here.

[0046] Specifically, refer to Figure 2 The feeding mechanism 200 also includes a second vision module 250, which is arranged opposite to the first vision module 240. The second vision module 250 is used to detect the position of the lens 500 and is electrically connected to the controller. The second vision module 250, arranged opposite to the first vision module 240, can detect the lens 500 from multiple angles, thereby enhancing the detection accuracy of the lens 500, facilitating the adjustment of the lens 500's position by the rotating component 430, improving the positional stability of the lens 500, and contributing to improved bonding quality.

[0047] It should be noted that, referring to Figure 4 The second vision module 250 is arranged below the tray 210 so that after the rotating component 430 adjusts the placement angle of the lens 520, the position of the adjusted rear lens 520 can be checked through the second vision module 250, and the rotating component 430 can be controlled by the controller to move to further adjust the position of the lens 520 and enhance the position accuracy of the lens 520.

[0048] Understandably, referring to Figure 3 An adjusting plate 420 is fixedly connected to an adjusting block 421. The adjusting block 421 has a positioning hole 422, the shape of which is the same as that of the lens 500. The adjusting plate 420 is fixedly connected to the adjusting block 421. By opening the positioning hole 422 on the adjusting block 421, the lens 500 can be inserted into the positioning hole 422, thereby locking the lens 500 in the positioning hole 422. This facilitates the adjusting block 421 in moving the lens 500, reduces the positional offset of the lens 500, and allows for convenient automatic alignment of the optical centers of multiple lenses 500, improving the bonding quality of the lenses 500.

[0049] It should be noted that by setting the shape of the positioning hole 422 to match the shape of the lens 500, the lens 500 can be stably placed within the positioning hole 422, which facilitates the adjustment block 421 to push the lens 500 to move, reduces the positional offset of the lens 500, and improves the bonding quality of the lens 500.

[0050] Understandably, referring to Figure 1 and Figure 4 The adjustment mechanism 400 also includes a collimator 440, which is positioned above the stage 100. The collimator 440 is used to detect the optical center of the lens 500. Both the collimator 440 and the moving component 410 are electrically connected to the controller. The collimator 440, positioned above the stage 100, can accurately detect the optical center of the lens 500, ensuring precise positioning of the lens 500 during the bonding process. This effectively prevents optical performance degradation caused by positional deviations of the lens 500.

[0051] In addition, by setting the collimator 440 and the moving component 410 to be electrically connected to the controller, the controller can control the operation of the moving component 410 according to the optical center of the lens 500 detected by the collimator 440. This allows the moving component 410 to drive the adjustment plate 420 to move automatically, replacing manual adjustment of the position of the lens 500, thereby achieving automatic bonding of the lens 500 and improving the production efficiency and quality of the lens 500.

[0052] It should be noted that the adjustment mechanism 400 also includes a test light source 450, which emits light onto the stage 100. The collimator 440 works in conjunction with the test light source 450 to detect the optical center of the lens 500. By emitting light onto the lens 500 through the test light source 450, the collimator 440 can detect the optical center of the lens 500 based on the angle of the light, which helps to improve the efficiency of light adjustment.

[0053] Understandably, referring to Figure 1 and Figure 4The dispensing mechanism 300 also includes a curing lamp 330, which is arranged adjacent to the platform 100. The curing lamp 330 is used to irradiate the adhesive. The adjacent arrangement of the curing lamp 330 and the platform 100 allows for irradiation of the platform 100, accelerating the curing of the adhesive. This not only shortens the bonding time of the lens 500 and improves production efficiency, but also enhances the uniformity and stability of the adhesive curing, thereby improving the quality and strength of the lens 500 bonding.

[0054] It should be noted that the curing lamp 330 can be an ultraviolet lamp, so that the light emitted by the curing lamp 330 can accelerate the curing of the adhesive and improve the production efficiency of the curing process.

[0055] Specifically, refer to Figure 1 The dispensing mechanism 300 also includes a third driving member 331, which drives the curing lamp 330 to move closer to or further away from the platform 100. The curing lamp 330 is connected to the movable end of the third driving member 331. The third driving member 331 can drive the curing lamp 330 to move closer to or further away from the platform 100, thereby facilitating the adjustment of the distance between the curing lamp 330 and the platform 100, and thus adjusting the curing time of the adhesive, avoiding uneven curing rates, and improving the bonding quality of the lens 500.

[0056] The third driving component 331 can be a linear cylinder, an electric actuator, a linear slide module, etc., and is not limited here.
