[0056] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0057] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0059] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0060] As Figure 1As shown in the figure, this embodiment provides a lens gluing device, which includes a frame 1, a material storage device 2, a dispensing device 3, a pressing device 4, and a material transfer device 5. The material storage device 2 is installed on the frame 1 and is used to provide upper lenses and lower lenses; the dispensing device 3 is used to drip glue onto the lower lenses; the pressing device 4 is installed on the frame 1 and is located downstream of the material storage device 2, and the pressing device 4 is used to press the upper lens onto the lower lens; the material transfer device 5 includes a middle turntable 51, a handling mechanism 52, and a linear driving mechanism 53. The handling mechanism 52 is used to transfer the workstations for handling and transferring upper lenses, lower lenses, or lens products. The linear driving mechanism 53 can be set as a mechanism driven by a motor driving a lead screw nut pair or a mechanism directly driven by a cylinder. The linear driving mechanism 53 is installed on the frame 1, and the middle turntable 51 is connected to the execution end of the linear driving mechanism 53. The linear driving mechanism 53 can drive the middle turntable 51 to reciprocate between the workstations of the handling mechanism 52 and the pressing device 4. When the lens gluing device executes the lens gluing process, first, the middle turntable 51 is located at the workstation of the handling mechanism 52. The handling mechanism 52 first transports the upper lens and the lower lens from the material storage device 2 to the middle turntable 51, and the dispensing device 3 drips glue onto the lower lens; then the linear driving mechanism 53 drives the middle turntable 51 to move to the workstation of the pressing device 4. The pressing device 4 takes away the upper lens and the lower lens on the middle turntable 51 and presses the upper lens onto the lower lens. At this time, the middle turntable 51 returns to the workstation of the handling mechanism 52, and the handling mechanism 52 can continue to transport the upper lens and the lower lens from the material storage device 2 to the middle turntable 51 without waiting time; then the middle turntable 51 moves to the workstation of the pressing device 4. The pressing device 4 places the glued lens product on the middle turntable 51 and directly takes away the upper lens and the lower lens from the middle turntable 51 without multiple movements; finally, the middle turntable 51 returns to the workstation of the handling mechanism 52 again. The handling mechanism 52 can continue to place the upper lens and the lower lens on the middle turntable 51 and then take away the lens product from the middle turntable 51 without moving back and forth. It can be understood that in the gluing process, the middle turntable 51 realizes the simultaneous execution of the feeding process of the handling mechanism 52 and the pressing process of the pressing device 4, and the feeding and discharging of the handling mechanism 52 are carried out at the same workstation, and the discharging and taking of the pressing device 4 are carried out at the same workstation, improving the material transfer efficiency and thus improving the lens gluing efficiency. In other embodiments of the present invention, the dispensing device 3 can also drip glue onto the upper lens or drip glue onto both the upper lens and the lower lens, which can also make the upper lens and the lower lens adhere. In other embodiments of the present invention, the middle turntable 51 can also be fixed to the frame 1, and then the pressing device 4 is connected to the execution end of the linear driving mechanism 53. The same workstation switching of the middle turntable 51 can be realized by the movement of the pressing device 4.

[0061] As Figure 2As shown in the figure, in this embodiment, the pressing device 4 includes a lifting drive mechanism 41, a first suction mechanism 42, and a second suction mechanism 43. The lifting drive mechanism 41 includes a sixth drive member 411. The sixth drive member 411 can be set as a motor or a cylinder drive. The sixth drive member 411 of this embodiment includes a motor and a lead screw nut pair. The motor is installed on the support frame 451, and the lead screw nut pair is connected to the output end of the motor. The first suction mechanism 42 is connected to the nut of the lead screw nut pair. The first suction mechanism 42 is used to suck the upper lens on the middle turntable 51, and the second suction mechanism 43 is used to suck the lower lens on the middle turntable 51. When pressing the upper lens and the lower lens together, the lifting drive mechanism 41 drives the first suction mechanism 42 to move the upper lens in the vertical direction, so that the upper lens approaches the lower lens on the lower second suction mechanism 43 and is pressed on the lower lens, thereby realizing the gluing of the upper lens and the lower lens.

[0062] As Figure 2 , Figure 3 and Figure 4 shown, the pressing device 4 further includes a jacking mechanism 44. The structure of the jacking mechanism 44 is the same as that of the lifting drive mechanism 41, and also includes a motor and a lead screw nut pair. The motor is installed on the mounting block 433, and the mounting block 433 is fixed to the frame 1. The lead screw nut pair is connected to the output end of the motor. The second suction mechanism 43 is connected to the nut of the lead screw nut pair; a material taking groove 511 extending in the horizontal direction is formed on the middle turntable 51. The opening of the material taking groove 511 faces the second suction mechanism 43. A first accommodating groove 512 is formed at one end of the material taking groove 511 away from the second suction mechanism 43. The first accommodating groove 512 extends in the vertical direction, and the structure is simple. When the pressing process of the pressing device 4 is completed, the linear drive mechanism 53 drives the middle turntable 51 to move in the direction close to the second suction mechanism 43 so that the second suction mechanism 43 can enter the first accommodating groove 512 through the material taking groove 511. Then, the jacking mechanism 44 drives the second suction mechanism 43 to descend in the first accommodating groove 512 in the vertical direction and place the lens finished product in the first accommodating groove 512, thereby completing the blanking of the lens finished product.

[0063] In this embodiment, a material taking hole 513 is further formed in the middle turntable 51. The aperture of the material taking hole 513 at one end close to the second suction mechanism 43 is larger than that at the end far from the second suction mechanism 43. The material taking hole 513 is in a gourd shape. The lower lens can pass through the end of the material taking hole 513 close to the second suction mechanism 43, but cannot pass through the end of the material taking hole 513 far from the second suction mechanism 43. A second accommodating groove 514 extending in the vertical direction is formed at the end of the material taking hole 513 far from the second suction mechanism 43. The second accommodating groove 514 is communicated with the material taking hole 513, and the bottom area of the second accommodating groove 514 is larger than the aperture of this end of the material taking hole 513, so that the lower lens can be placed in the second accommodating groove 514, and the structure is simple. When the pressing process of the pressing device 4 is completed, the linear driving mechanism 53 drives the middle turntable 51 to move in the direction close to the second suction mechanism 43 so that the second suction mechanism 43 is located directly below the second accommodating groove 514. Then, the lifting mechanism 44 drives the second suction mechanism 43 to rise vertically in the second accommodating groove 514 and eject the lower lens in the second accommodating groove 514. After that, the linear driving mechanism 53 drives the middle turntable 51 away from the second suction mechanism 43 so that the second suction mechanism 43 is located directly below the other end of the material taking hole 513. Then, the lifting mechanism 44 drives the second suction mechanism 43 to descend, and the lower lens can be taken off the middle turntable 51. In other embodiments of the present invention, twice the number of material taking grooves 511 and first accommodating grooves 512 can also be formed in the middle turntable 51. The material taking grooves 511 for placing the finished lens and the material taking grooves 511 for placing the lower lens are arranged at intervals on the middle turntable 51. After the second suction mechanism 43 places the finished lens, the middle turntable 51 can still move longitudinally so that the second suction mechanism 43 is aligned with the material taking groove 511 for placing the lower lens. Then, the second suction mechanism 43 takes out the lower lens from the material taking groove 511.

[0064] In this embodiment, a third accommodating groove 515 is further formed in the middle turntable 51 for placing the upper lens. When the pressing process of the pressing device 4 is completed, the linear driving mechanism 53 drives the middle turntable 51 to move in the direction close to the first suction mechanism 42 so that the first suction mechanism 42 is located directly above the third accommodating groove 515. Then, the lifting mechanism 44 drives the first suction mechanism 42 to descend vertically and take away the upper lens in the third accommodating groove 515.

[0065] As a preferred embodiment, in a direction away from the pressing device 4, the material taking groove 511, the material taking hole 513 and the third accommodating groove 515 are arranged in sequence. It can be understood that after the pressing process of the pressing device 4 is completed, the middle turntable 51 moves in a direction close to the pressing device 4. The second suction mechanism 43 first places the finished lens in the first accommodating groove 512 at the end of the material taking groove 511, and then the first suction mechanism 42 takes out the upper lens from the third accommodating groove 515. Finally, the middle turntable 51 moves in a direction away from the pressing device 4, and the second suction mechanism 43 takes out the lower lens from the second accommodating groove 514 at the end of the material taking hole 513. When the pressing device 4 is feeding and taking materials, the actions are coherent and the working efficiency is high.

[0066] As Figure 2 and Figure 5 shown, the first suction mechanism 42 includes a pressing plate 421. The pressing plate 421 is installed on the upper fixing block 422. A lower fixing block 432 is arranged below the upper fixing block 422. The lower fixing block 432 is fixed to the mounting block 433. One end of the guiding column 46 is fixed to the upper fixing block 422, and the other end is slidably arranged in the lower fixing block 432. The guiding column 46 can provide guidance for the movement of the first suction mechanism 42. And adsorption holes are formed in the pressing plate 421. The number of the adsorption holes can be set as required. In this embodiment, five adsorption holes are formed. The five adsorption holes are communicated with an external air suction device. The air suction device provides a negative pressure environment for the adsorption holes so that the adsorption holes can respectively suck the upper lenses on the middle turntable 51. Specifically, the execution end of the lifting driving mechanism 41 is connected to the upper fixing block 422 through a connecting block 412. The pressing plate 421 is installed on the upper fixing block 422 so that the lifting driving mechanism 41 can drive the pressing plate 421 to move in a direction close to or away from the second suction mechanism 43. In other embodiments of the present invention, a suction pen can also be directly installed on the upper fixing block 422. The suction pen faces the second suction mechanism 43 and can realize the same function of sucking the upper lens.

[0067] As a preferred embodiment, the pressing device 4 further includes a counterweight mechanism 45. The counterweight mechanism 45 is installed on the support frame 451 and is connected to the pressing plate 421. It can be understood that the counterweight mechanism 45 can pull the pressing plate 421 to balance the weights of the pressing plate 421, the upper fixing block 422 and the guiding column 46, so as to reduce the load of the lifting driving mechanism 41, thereby reducing the load on the motor and increasing the service life of the motor.

[0068] Specifically, the counterweight mechanism 45 includes a support frame 451, a counterweight 452, gears 453 and a chain 454. The support frame 451 is installed on the frame 1. A guide rail is installed on the side of the support frame 451 away from the pressing device 4. The guide rail extends in the vertical direction. A slider is installed on the counterweight 452, and the slider is slidably connected to the guide rail. Gears 453 are rotatably arranged on the support frame 451. The number of gears 453 can be set as required. In this embodiment, two gears 453 are provided, and the two gears 453 are respectively located at both ends of the top of the support frame 451. Of course, in other embodiments, the gears 453 can also be arranged at other positions of the support frame 451, as long as the position height of the gears 453 is greater than the position heights of the pressing plate 421 and the counterweight 452. The chain 454 is engaged with the gears 453, and one end of the chain 454 is connected to the pressing plate 421, and the other end is connected to the counterweight 452. The counterweight 452 can balance the weights of the pressing plate 421, the upper fixing block 422 and the guide post 46 through the chain 454, and the structure is simple. In other embodiments of the present invention, a winch can also be installed on the support frame 451, and the execution end of the winch is connected to the pressing plate 421. The winch can achieve the same counterweight function by pulling the pressing plate 421.

[0069] Such as Figure 5 and Figure 6As shown, the second suction mechanism 43 includes a first suction pen 431. The number of the first suction pens 431 can be set as required. In this embodiment, five first suction pens 431 are provided, and the five first suction pens 431 correspond to the suction holes on the pressing plate 421 one by one. The first suction pen 431 is connected to the execution end of the lifting mechanism 44 and slides through the lower fixing block 432 and the mounting block 433. The pressing device 4 includes a shaping mechanism 47. The shaping mechanism 47 includes a first driving member 471, a first shaping plate 472 and a second shaping plate 473. The first driving member 471 can be set as a cylinder or an electric push rod. The first driving member 471 in this embodiment is a cylinder. The first shaping plate 472 and the second shaping plate 473 are respectively connected to the output ends of two cylinders, and the two cylinders are respectively mounted on the lower fixing block 432. Among them, a first shaping groove 4721 is formed on the first shaping plate 472. The first shaping groove 4721 is semi-circular. A second shaping groove 4731 is formed on the second shaping plate 473. The shape of the second shaping groove 4731 is also semi-circular. The complete circle formed by the combination of the first shaping groove 4721 and the second shaping groove 4731 matches the outer peripheral shape of the first suction pen 431. And the first shaping plate 472 is further provided with a fitting groove 4722, and a fitting boss 4732 is formed on the second shaping plate 473. The fitting boss 4732 can be inserted into the fitting groove 4722 to enable the first shaping plate 472 and the second shaping plate 473 to be fitted with each other. After the first suction pen 431 sucks the lower lens, the two cylinders can drive the first shaping plate 472 and the second shaping plate 473 to approach each other and then fit together. At the first shaping groove 4721 and the second shaping groove 4731, the first shaping plate 472 and the second shaping plate 473 can clamp the first suction pen 431 to calibrate the positional accuracy of the first suction pen 431, improving the reliability of the pressing of the pressing device 4. In other embodiments of the present invention, one of the first shaping plate 472 and the second shaping plate 473 can also be fixed on the lower fixing block 432, and the other is connected to the output end of the cylinder, which can achieve the same function.

[0070] As Figure 1 , Figure 7 and Figure 8As shown in the figure, the handling mechanism 52 includes a robotic arm 521, an upper lens handling component 522, a lower lens handling component 523, and a finished product handling component 524. The execution end of the robotic arm 521 is provided with a base 5211, and the robotic arm 521 can drive the base 5211 to achieve multi-degree-of-freedom movement; the upper lens handling component 522, the lower lens handling component 523, and the finished product handling component 524 are all connected to the base 5211. The upper lens handling component 522 and the lower lens handling component 523 are installed on one side of the base 5211, and the finished product handling component 524 is installed on the other side of the base 5211, with a compact structure. When the middle turntable 51 drives the lens finished product to move to the station of the handling mechanism 52, the upper lens handling component 522 places the upper lens from the storage device 2 onto the middle turntable 51, and the lower lens handling component 523 places the lower lens from the storage device 2 onto the middle turntable 51. Then, the finished product handling component 524 takes away the lens finished product from the middle turntable 51, with high working efficiency.
