[0040] This embodiment discloses a lens assembly line including a lens assembly machine. Figure 1 The lens assembly machine includes a connecting and conveying guide rail assembly 100, a lateral movement module 210, a material suction module 220, a pressing module 230, a lens material cage lifting mechanism 310 and a lens tray transfer mechanism 320. The length of the docking and conveying guide rail assembly 100 extends along a first direction, which is indicated as the X-axis direction. The transverse moving module 210 is installed above the docking and conveying guide rail assembly 100, and its length extends along a second direction, which is indicated as the Y-axis direction. The suction module 220 is installed at the first end of the transverse moving module 210 and can be moved to the working position of the docking and conveying guide rail assembly 100 under the drive of the transverse moving module 210. The pressing module 230 is installed at the second end of the transverse moving module 210 and can be moved to the working position of the docking and conveying guide rail assembly 100 under the drive of the transverse moving module 210. The lens material cage lifting mechanism 310 is used to carry the lens material cage 10 with a lens tray placed thereon, wherein the lens material cage 10 has a plurality of compartments arranged along the longitudinal direction, each compartment can hold a lens tray, and each lens tray can hold a plurality of lenses. The first end of the lens tray transfer mechanism 320 extends to the lens material cage lifting mechanism 310, and the second end of the lens tray transfer mechanism 320 is located below the suction module 220.

[0041] When in use, the equipment at the previous workstation transports the carrier with the semi-finished lens products to the docking conveying guide assembly 100, and the docking conveying guide assembly 100 transports the carrier with the semi-finished lens products to a preset workstation, such as the intersection of the moving trajectories of the docking conveying guide assembly 100 and the suction module 220 in the top-view plane, and the lens tray transfer mechanism 320 takes out the tray with the lenses from the lens cage lifting mechanism 310 and moves it to the bottom of the suction module 220, so that the suction module 220 can absorb the lenses on the lens tray, and the transverse module 210 drives the suction module 220 and the pressing module 230 to complete the suction, discharge and pressing operations of the lenses, for example, the suction module 220 descends to the lens tray The suction module 220 moves to the plane where the lens is located and absorbs the lens, then rises to a preset height, and the suction module 220 moves to the working position of the docking and conveying guide rail assembly 100 under the drive of the transverse movement module 210, and the suction module 220 descends and places the lens into the semi-finished lens product, and then the suction module 220 moves to the material picking position of the next lens to absorb the next lens; at the same time, the pressing module 230 moves to the working position of the docking and conveying guide rail assembly 100 under the drive of the transverse movement module 210, descends and press-fits the lens, and resets after the press-fitting is completed to avoid the suction module 220. When all the semi-finished lenses on the carrier are assembled, the carrier is transported to the next station through the docking and conveying guide rail assembly 100 to realize the automatic assembly of the lenses.

[0042] Please refer to Figure 1and Figure 2 The docking conveying rail assembly 100 includes a feed conveying mechanism 110, a discharge conveying mechanism 120 and a stage mechanism 130. The stage mechanism 130 has a first working position, a second working position and a third working position. The first working position of the stage mechanism 130 is adapted to the feed conveying mechanism 110, the second working position of the stage mechanism 130 is adapted to the discharge conveying mechanism 120, and the third working position of the stage mechanism 130 is located between the first working position and the second working position. After the stage mechanism 130 moves to the first working position to take out the carrier with the semi-finished lens product from the feed conveying mechanism 110 and moves it to a preset working position, the feed conveying mechanism 110 can receive the next semi-finished lens product carrier for carrier caching. The stage mechanism 130 moves from the first working position to the third working position, so that the semi-finished lens carrier is in a relatively independent working position, reducing interference in the lens assembly process, which is conducive to improving assembly accuracy. After completing the lens assembly, the stage mechanism 130 moves the semi-finished lens carrier from the third working position to the second working position to transfer the semi-finished lens carrier to the discharge conveying mechanism 120. The discharge conveying mechanism 120 caches or sends out the semi-finished lens carrier according to the situation of the next station equipment. In this way, the connecting conveying guide rail assembly 100 can connect the previous station and the next station, so as to cooperate with different equipment to form a lens assembly line to complete more functions.

[0043] Please refer to Figure 2 The carrier mechanism 130 includes a first linear motion module 131 and a carrier 132. The first end of the first linear motion module 131 extends to the feeding conveying mechanism 110, and the second end of the first linear motion module 131 extends to the discharging conveying mechanism 120. The carrier 132 is mounted on the first linear motion module 131. The carrier 132 is a vacuum carrier, which is used to vacuum adsorb the semi-finished lens carrier to improve the placement stability of the semi-finished lens carrier. The carrier 132 can be switched between the first working position, the second working position and the third working position under the drive of the first linear motion module 131, thereby realizing the transfer of the semi-finished lens carrier.

[0044] Please continue to refer to Figure 2The feeding conveying mechanism 110 and the discharging conveying mechanism 120 both include a lifting frame and a conveying guide rail, and the conveying guide rail is arranged on the lifting frame. For example, the feeding conveying mechanism 110 includes a first lifting frame 111 and a first conveying guide rail 112, and the first conveying guide rail 112 is a synchronous belt conveying guide rail. The first conveying guide rail 112 is lifted or lowered under the drive of the first lifting frame 111. When the carrier platform 132 moves to the bottom of the first lifting frame 111 under the drive of the first linear motion module 131, the first lifting frame 111 drives the first conveying guide rail 112 to descend, so that the semi-finished lens carrier on the first conveying guide rail 112 is adsorbed on the carrier platform 132, and the carrier platform 132 moves to the third working position. The first conveying guide rail 112 is reset under the drive of the first lifting frame 111 to receive the next semi-finished lens carrier. Similarly, the discharge conveying mechanism 120 includes a second lifting frame 121 and a second conveying rail 122. When the platform mechanism 130 needs to transfer the semi-finished lens carrier to the discharge conveying mechanism 120, the second lifting frame 121 drives the second conveying rail 122 to descend, and the carrier platform 132 moves to the second working position under the drive of the first linear motion module 131. At this time, the semi-finished lens carrier is located above the second conveying rail 122, and the second lifting frame 121 drives the second conveying rail 122 to lift, so that the second conveying rail 122 carries and lifts the semi-finished lens carrier.

[0045] Please refer to Figure 1 and Figure 3 The lens tray transfer mechanism 320 includes a second linear motion module 321 and a tray support frame 322. The first end of the second linear motion module 321 extends to the lens cage lifting mechanism 310, and the second end of the second linear motion module 321 extends to the bottom of the suction module 220. The tray support frame 322 is mounted on the second linear motion module 321. The lens cage 10 is provided with an avoidance position adapted to the tray support frame 322. When the tray support frame moves to the adapted position of the lens cage lifting mechanism 310 under the drive of the second linear motion module 321, the tray support frame is located below the lens tray 20. At this time, the lens cage lifting mechanism 310 descends, so that the lens tray 20 falls on the tray support frame. The second linear motion module 321 drives the tray support frame to move from the first end to the second end, so that the tray support frame and the lens tray 20 leave the position of the lens cage lifting mechanism 310, so that the suction assembly can suck a single lens on the lens tray 20.

[0046] Please refer to Figure 4 In some application examples, a first camera module 410 is provided at the second end of the lens tray transfer mechanism 320 and above the suction module 220. The first camera module 410 is used to perform image positioning of the lens on the lens tray, which is conducive to quickly and accurately identifying the position of the lens.

[0047] Alternatively, in some other application examples, a second camera module 420 is arranged below the suction module 220 and on the moving path of the suction module 220. The second camera module 420 is used to identify the posture of the lens sucked by the suction module 220 to facilitate adjusting the placement angle of the lens, thereby improving the accuracy of lens assembly.

[0048] Alternatively, in some other application examples, a first camera module 410 is provided at the second end of the lens tray transfer mechanism 320 and above the suction module 220, and a second camera module 420 is provided below the suction module 220 and on the moving path of the suction module 220. Through the cooperation of the first camera module 410 and the second camera module 420, the lenses can be picked up quickly and accurately, and the angle accuracy of the lens assembly can be improved.

[0049] Please refer to Figure 4 or Figure 5 A third camera module 430 is disposed above the working position of the connecting conveyor rail assembly 100. The third camera module 430 can move in the second direction. The third camera module 430 is used to locate and identify the position to be assembled of the semi-finished lens carrier, so as to quickly and accurately identify the placement position of the lens. In addition, the cooperation of the first camera module 410, the second camera module 420 and the third camera module 430 is conducive to improving the accuracy of lens assembly.

[0050] In some application examples, the lens assembly machine is used to assemble the lens semi-finished products in one direction, that is, to assemble the lens semi-finished products in one direction, while in other application examples, the lens assembly machine can be used to assemble the lens semi-finished products in two directions, that is, to assemble the lens semi-finished products in both the positive and negative directions. For this purpose, please refer to Figure 6 A carrier flipping mechanism 500 is provided on one side of the connecting conveying guide rail assembly 100. The carrier flipping mechanism 500 is used to flip the semi-finished lens product carrier so as to facilitate assembly of the semi-finished lens product from another direction.

[0051] Please refer to Figure 7 and Figure 8The carrier flipping mechanism 500 includes a lifting unit 510, a first clamping arm 520, a second clamping arm 530, a synchronization shaft 540 and a flipping drive cylinder 550. The first clamping arm 520 and the second clamping arm 530 are both installed on the lifting unit 510. The first clamping arm 520 is rotatably mounted with a first clamping claw 521, and the second clamping arm 530 is rotatably mounted with a second clamping claw 531. The synchronization shaft 540 is rotatably connected to the first clamping arm 520 and the second clamping arm 530. The first clamping claw 521 and the second clamping claw 531 are respectively connected to the synchronization shaft 540 through the first transmission belt 522 and the second transmission belt 532. The flipping drive cylinder 550 is connected to the first transmission belt 522 or the second transmission belt 532. The first clamping arm 520 and the second clamping arm 530 can clamp the semi-finished lens carrier and realize the lifting movement through the lifting unit 510. The flipping drive cylinder 550 converts the linear motion into rotational motion through the first transmission belt 522 or the second transmission belt 532, thereby realizing the rapid rotation of the first clamping jaw 521 or the second clamping jaw 531, and the first clamping jaw 521 and the second clamping jaw 531 realize synchronous rotation through the first transmission belt 522, the second transmission belt 532 and the synchronization shaft 540. In this way, the semi-finished lens carrier can be turned over, thereby realizing batch assembly of multiple lenses in the semi-finished lens carrier, which is beneficial to improving assembly efficiency.

[0052] Among them, the suction module 220 includes a first longitudinal moving unit, a first rotating unit and a suction nozzle, the suction nozzle is connected to the first rotating unit, and the first rotating unit is installed on the first longitudinal moving unit; the pressing module 230 includes a second longitudinal moving unit, a second rotating unit and a pressure rod, the pressure rod is connected to the second rotating unit, and the second rotating unit is installed on the second longitudinal moving unit.
