[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 9 This invention provides an assembly device for a single-beam lens module, including an assembly platform 1 and a clamping mechanism connected to the assembly platform 1. The clamping mechanism includes a rotating ring 17, multiple connecting plates 41, multiple moving blocks 29, and an elastic pressing block. The rotating ring 17 is rotatably connected to the assembly platform 1. The two ends of the connecting plates 41 are connected to the moving blocks 29 and the rotating ring 17. The elastic pressing block is connected to the moving blocks 29. A side plate 5 is connected to the back of the assembly platform 1. A toothed plate 38 for driving the rotating ring 17 to rotate is connected to the side plate 5. A top plate 2 is connected to the top of the side plate 5. A gripping mechanism for gripping a lens 36 is connected to the top plate 2. The gripping mechanism is used to drive the toothed plate 38 to move. The assembly platform 1 is connected to a feeding mechanism and a discharging mechanism. The gripping mechanism is matched with the feeding mechanism.

[0020] The lens 36 is transported to the top of the assembly table 1 via a gripping mechanism. During this movement, the moving plate 8 moves synchronously, applying a pushing force to the push plate 23, which in turn drives the toothed plate 38 to move. The spring 39 is compressed, and the toothed plate 38 drives the rotating ring 17 to rotate. The rotating ring 17 simultaneously applies a pushing force to the three connecting plates 41, causing the three moving blocks 29 to move synchronously towards the center of the rotating ring 17. This presses the three pressing blocks 32 against the lens holder 16, correcting the position of the lens holder 16, improving its stability, and facilitating subsequent assembly of the lens 36 with the lens holder 16. The gripping mechanism then drives the lens 36 to descend, pressing it against the lens holder 16. The snap-fit ​​block 34 inside the lens holder 16 engages with the snap-fit ​​groove 35 of the lens 36, improving the stability of the connection between the lens 36 and the lens holder 16, achieving rapid assembly with high efficiency.

[0021] The clamping mechanism also includes multiple rectangular holes 33, and the moving block 29 is slidably connected to the rectangular holes 33. The rectangular holes 33 guide the moving block 29, thereby improving the stability of the reciprocating movement of the elastic clamping block.

[0022] The elastic clamping block includes a pressing cylinder 30, a pressing rod 31, a pressing block 32, and a spring 37. The end of the pressing cylinder 30 is connected to the moving block 29. The pressing rod 31 is slidably connected inside the pressing cylinder 30, and its end is fixedly connected to the pressing block 32. Both ends of the spring 37 are connected to the pressing rod 31 and the pressing cylinder 30. During the movement of the lens 36 to the appropriate position, the pressing block 32 presses against the outside of the lens support 16, correcting its position. Then, the moving block 29 continues to move forward, synchronously driving the pressing cylinder 30 forward. The pressing rod 31 slides relative to the pressing cylinder 30, and the spring 37 is compressed, causing the pressing block 32 to press firmly against the lens support 16. This improves the stability of the lens support 16, facilitates subsequent docking with the lens 36, and can accommodate the limiting of lens supports 16 of different diameters, making it highly adaptable.

[0023] The toothed plate 38 meshes with the rotating ring 17, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio. A push plate 23 is connected to one end of the toothed plate 38, which is slidably connected to the side plate 5. A guide rod 40 is connected to the other end of the toothed plate 38, with its end fixed to the side plate 5. The guide rod 40 and push plate 23 provide good guidance for the toothed plate 38, improving the stability of its reciprocating movement and ensuring the transmission effect between the toothed plate 38 and the rotating ring 17.

[0024] The guide rod 40 is fitted with a second spring 39. The two ends of the second spring 39 are connected to the toothed plate 38 and the side plate 5. The toothed plate 38 has a sliding groove, and the guide rod 40 is slidably connected to the sliding groove. After the transparent module is assembled, the gripping mechanism returns to its original position, the moving plate 8 separates from the pushing plate 23, the compressed second spring 39 drives the toothed plate 38 to return to its original position, and the toothed plate 38 drives the rotating ring 17 to rotate. With the use of the connecting plate 41, the three moving blocks 29 return to their original positions simultaneously, that is, the three pressing blocks 32 separate from the transparent bracket 16, thereby separating the transparent module and achieving the purpose of loosening.

[0025] The gripping mechanism includes a guide hole 3, a stud 4, a sliding block 6, a motor 9, a mounting base 10, a cylinder 11, an air extraction pipe 12, a vacuum pump 13, a hose 25, an interface 26, a connector 27, and a suction cup 28. The motor 9 drives the stud 4 to rotate. The stud 4 is threadedly connected to the sliding block 6. The sliding block 6 is slidably connected to the guide hole 3. The top plate 2 is connected to the top of the side plate 5. The guide hole 3 is located on the top plate 2. The mounting base 10 is connected to the sliding block 6. The cylinder 11 and the vacuum pump 13 are fixed to the mounting base 10. The power output end of the cylinder 11 is connected to the air extraction pipe 12. The connector 27 is connected to the bottom of the air extraction pipe 12. The suction cup 28 is detachably connected to the connector 27. Both ends of the hose 25 are connected to the interface 26 and the vacuum pump 13.

[0026] Motor 9 drives stud 4 to rotate, causing sliding block 6 to reciprocate along the length of guide hole 3. During gripping, cylinder 11 drives suction pipe 12, connector 27, and suction cup 28 to descend. Suction cup 28 presses against lens 36, facilitating position correction and ensuring the top of lens 36 is horizontal. Then, vacuum pump 13 evacuates hose 25, creating negative pressure on suction pipe 12 and suction cup 28, allowing suction cup 28 to adhere and fix lens 36, improving the stability of lens 36's movement. Sliding block 6 then moves lens 36 to a position directly above assembly table 1. Finally, cylinder 11 drives lens 36 to descend again, facilitating engagement with lens bracket 16.

[0027] When the sliding block 6 moves, it synchronously drives the mounting base 10 and the moving plate 8 to move. The moving plate 8 pushes the push plate 23 and the toothed plate 38 forward, so that the clamping mechanism clamps the lens bracket 16.

[0028] Mounting base 10 is connected to a movable plate 8, which is used to drive the toothed plate 38 to move forward. The movable plate 8 is also connected to a guide post 7, which is slidably connected to the side plate 5.

[0029] The feeding mechanism includes a support 19, multiple placement slots 20, a feeding rack 21, a transmission belt 22, two rotating rollers, and a motor 24. The end of the feeding rack 21 is connected to the assembly table 1. The rotating rollers are rotatably connected within the feeding rack 21, and the two rotating rollers are connected via the transmission belt 22. The support 19 is connected to the transmission belt 22. The multiple placement slots 20 are located on the support 19. The motor 24 is connected to the feeding rack 21, and its power output is connected to the rotating rollers. A robotic arm is equipped next to the feeding rack 21. The robotic arm picks up individual lenses 36 and places them into the placement slots 20. The placement slots 20 match the lenses 36 and have an arc-shaped cross-section for stable support. Motor 24 drives the rotating roller to rotate, which in turn drives the transmission belt 22 to rotate. The transmission belt 22 drives the support 19 to rotate, causing the placement slot 20 to move forward in sequence until the lens 36 moves to the position to be gripped. Then the transmission belt 22 stops rotating, and the gripping mechanism is used to grip the lens 36 for easy subsequent assembly.

[0030] A second cylinder 14 is connected to the inner side of the side plate 5, and the power output end of the second cylinder 14 is connected to the push block 15. After the lens module is assembled, the second cylinder 14 drives the push block 15 to move forward, moving the lens module onto the unloading mechanism. The unloading mechanism then transfers the lens module to the next process for inspection and processing.

[0031] The discharge mechanism and the feeding mechanism have similar structures, but the discharge mechanism does not have a support 19 or a placement slot 20. The lens module is transported by the transmission belt 22 on the discharge mechanism.

[0032] The single-beam lens module includes a lens bracket 16 and a lens 36. The bottom of the lens 36 is provided with four snap-fit ​​slots 35, and the inner side of the lens bracket 16 is connected with four snap-fit ​​blocks 34. The snap-fit ​​blocks 34 are engaged with the snap-fit ​​slots 35 to improve the stability of the connection between the lens 36 and the lens bracket 16.
