Description

Technical Field

[0001] This invention relates to the field of lens assembly technology, specifically to an automatic lens mounting machine. Background Technology

[0002] During the assembly of the lens module, the inner pressure ring needs to be precisely locked into the lens barrel to secure the lens. Currently, the loading of existing products is mostly done manually, with a low degree of automation. This increases the labor intensity and reduces the efficiency of the loading process. Moreover, because the entire loading process requires manual operation, the loading position is not accurate enough, easily leading to missed loading or loading position deviations, thus reducing the yield rate during locking and causing significant production problems. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic lens attachment machine to solve the problems mentioned in the background art, such as low automation level of manual feeding, high labor intensity, low efficiency and inaccurate positioning.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic lens mounting machine, comprising a frame, a lens barrel feeding mechanism mounted on one side of the frame for feeding the lens barrel; an inner pressure ring feeding mechanism provided on the other side of the frame for feeding the inner pressure ring; a mounting mechanism provided on the surface of the frame for mounting the lens barrel and the inner pressure ring; a lens barrel feeding mechanism provided on one side of the lens barrel feeding mechanism for feeding the lens barrel from the lens barrel feeding mechanism into the mounting mechanism; and an inner pressure ring picking mechanism provided on one side of the inner pressure ring feeding mechanism for feeding the inner pressure ring from the inner pressure ring feeding mechanism into the mounting mechanism.

[0006] Preferably, the lens barrel feeding mechanism includes a hopper lifting module, a lens barrel hopper, and a tray transfer module. The hopper lifting module is installed inside the frame, and a lens barrel hopper with its own tray is fixed on the sliding seat of the hopper lifting module. The tray transfer module is installed on the surface of the frame and is used to transfer the tray in the lens barrel hopper to the lens barrel feeding mechanism.

[0007] Preferably, the inner pressure ring feeding mechanism consists of a flexible vibrating plate, a platform fixture, and an upper vision camera. The flexible vibrating plate and the platform fixture are fixed to the surface of the frame. The flexible vibrating plate is used to feed the inner pressure ring into the platform fixture. The upper vision camera is mounted on the surface of the frame and above the platform fixture via a bracket. The upper vision camera is used to position the inner pressure ring on the platform fixture.

[0008] Preferably, the locking mechanism includes an X-axis module, a Z-axis module, a pressure ring suction pen, and a material sensor. The X-axis module is mounted on the surface of the frame. The sliding seat of the X-axis module is equipped with a lens barrel locking platform for placing the lens barrel and an inner pressure ring locking platform for placing the inner pressure ring.

[0009] Preferably, a Z-axis module with an inner pressure ring sensing fiber is mounted on the surface of the frame, and a pressure ring suction pen is mounted on the surface of the Z-axis module. The pressure ring suction pen is used to attract and place the inner pressure ring into the lens barrel to achieve locking. A material sensor is mounted on the surface of the frame and on one side of the X-axis module via a bracket. The material sensor is used to sense whether there is a lens barrel on the lens barrel locking platform.

[0010] Preferably, the lens barrel loading mechanism consists of a dual-axis manipulator, a cylinder gripper, and a material sensor. The dual-axis manipulator is fixed to the surface of the frame, and two sets of cylinder grippers are installed on the sliding seat of the dual-axis manipulator.

The three-axis robot is fixed to the surface of the frame, and the picking pen and positioning camera are mounted on the surface of the three-axis robot. The picking pen is used to pick up the inner pressure ring in the carrier fixture and place it on the inner pressure ring locking platform of the locking mechanism. The positioning camera is used for visual positioning during placement.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This automatic lens mounting machine, by setting up a lens barrel feeding mechanism, a lens barrel loading mechanism, an inner pressure ring loading mechanism, an inner pressure ring picking mechanism, and a mounting mechanism, realizes the entire process from automatic feeding and loading of the lens barrel and inner pressure ring to automatic mounting, without the need for manual assistance throughout the process, greatly reducing the labor intensity of workers and significantly improving production efficiency; moreover, by setting up an upper vision camera and a positioning camera, visual positioning and correction are performed during the picking and unloading process, ensuring ultra-high precision in the picking, unloading, and mounting positions of the inner pressure ring, avoiding problems such as misalignment and omissions that are prone to occur in manual operation, thereby greatly improving the product mounting yield; at the same time, by setting up a hopper lifting module and a tray transfer module, automatic lifting and conveying of the lens barrel tray is realized, and in conjunction with a dual-axis robotic arm and a cylinder gripper, the continuity and stability of lens barrel loading are ensured, further improving the automation level and operational reliability of the equipment.

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.

[0021] The present invention provides a structure for an automatic lens mounting machine as follows: Figure 1 As shown, the equipment includes a frame 1, with a cover 11 mounted on the top of the frame 1. The surface of the cover 11 is inlaid with a control panel 12 for operating the equipment to start and stop and setting parameters. An FFU filter fan 13 is mounted on the top of the control panel 12 to ensure the cleanliness of the machine's interior.

[0022] Furthermore, such as Figure 2 and Figure 3 As shown, a lens barrel feeding mechanism 2 is installed on one side of the frame 1. The lens barrel feeding mechanism 2 is used for feeding lens barrels. The lens barrel feeding mechanism 2 includes a hopper lifting module 21, a lens barrel hopper 22, and a tray transfer module 23. The hopper lifting module 21 is installed inside the frame 1. The lens barrel hopper 22 with its own tray is fixed on the sliding seat of the hopper lifting module 21. The hopper lifting module 21 can drive the lens barrel hopper 22 to lift and lower to adjust the tray height. The tray transfer module 23 is installed on the surface of the frame 1. The tray transfer module 23 is used to transfer the tray in the lens barrel hopper 22 to the lens barrel loading mechanism 3.

[0023] During implementation, the lens barrel feeding mechanism 2 transports the tray filled with lens barrels to the picking position through the hopper lifting module 21 and the tray transfer module 23.

[0024] Furthermore, such as Figure 2 and Figure 4As shown, a lens barrel feeding mechanism 3 is provided on one side of the lens barrel feeding mechanism 2. The lens barrel feeding mechanism 3 is used to feed the lens barrels in the lens barrel feeding mechanism 2 into the locking mechanism 6. The lens barrel feeding mechanism 3 is composed of a dual-axis manipulator 31, a cylinder gripper 32 and a material sensor 33. The dual-axis manipulator 31 is fixed to the surface of the frame 1. Two sets of cylinder grippers 32 are installed on the sliding seat of the dual-axis manipulator 31. The cylinder grippers 32 are used to pick up and place the lens barrels on the tray on the surface of the tray transfer module 23. The material sensor 33 is used to detect whether there is material on the gripper.

[0025] During implementation, the dual-axis manipulator 31 of the lens barrel loading mechanism 3 drives the cylinder gripper 32 to pick up the lens barrel from the tray and place it in the lens barrel locking platform on the X-axis module 61 of the locking mechanism 6.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, an inner pressure ring feeding mechanism 4 is provided on the other side of the frame 1. The inner pressure ring feeding mechanism 4 is used for feeding inner pressure rings. The inner pressure ring feeding mechanism 4 consists of a flexible vibrating plate 41, a platform fixture 42, and an upper vision camera 43. The flexible vibrating plate 41 and the platform fixture 42 are fixed to the surface of the frame 1. The flexible vibrating plate 41 conveys the inner pressure rings in an orderly manner and feeds them into the platform fixture 42 through vibration. An upper vision camera 43 is mounted on the surface of the frame 1 and above the platform fixture 42 by a bracket. The upper vision camera 43 is used to take pictures and position the inner pressure rings on the platform fixture 42 to obtain their precise positions.

[0027] During implementation, the flexible vibratory feeder 41 of the inner pressure ring feeding mechanism 4 vibrates and transports the inner pressure ring to the platform fixture 42, and the upper vision camera 43 takes pictures and positions the inner pressure ring in the platform fixture 42.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, an inner pressure ring feeding mechanism 5 is provided on one side of the inner pressure ring feeding mechanism 4. This inner pressure ring feeding mechanism 5 is used to feed the inner pressure rings from the inner pressure ring feeding mechanism 4 into the locking mechanism 6. The inner pressure ring feeding mechanism 5 includes a three-axis robot 51, a material suction pen 52, and a positioning camera 53. The three-axis robot 51 is fixed to the surface of the frame 1. The material suction pen 52 and the positioning camera 53 are mounted on the surface of the three-axis robot 51. The material suction pen 52 is used to pick up the inner pressure rings from the platform fixture 42 according to the position information provided by the upper vision camera 43. The positioning camera 53 is used to take pictures of the inner pressure ring locking platform on the locking mechanism 6 before placement to achieve visual positioning during placement and ensure placement accuracy.

[0029] During implementation, the three-axis robot 51 of the inner pressure ring picking mechanism 5 drives the picking pen 52 to pick up the inner pressure ring according to the positioning information and moves it to the inner pressure ring locking platform on the X-axis module 61. Combined with the visual guidance of the positioning camera 53, the inner pressure ring is accurately placed on the platform.

[0030] Furthermore, such as Figure 2 and Figure 6 As shown, a locking mechanism 6 is provided on the surface of the frame 1. This locking mechanism 6 is used to lock the lens barrel and the inner pressure ring. The locking mechanism 6 includes an X-axis module 61, a Z-axis module 62, a pressure ring suction pen 63, and a material sensor 64. The X-axis module 61 is mounted on the surface of the frame 1. The sliding seat of the X-axis module 61 is equipped with a lens barrel locking platform for placing the lens barrel and an inner pressure ring locking platform for placing the inner pressure ring. The X-axis module 61 can drive these two platforms to move horizontally to switch work positions. The surface of the frame 1 is equipped with a... The Z-axis module 62 has an inner pressure ring sensing fiber, and a pressure ring suction pen 63 is installed on the surface of the Z-axis module 62. The pressure ring suction pen 63 is used to attract and lift the inner pressure ring placed on the inner pressure ring locking platform by the inner pressure ring picking mechanism 5, and then put it into the X-axis module 61 and move it into the lens barrel below it. Locking is achieved by rotating and pressing down. A material sensor 64 is installed on the surface of the frame 1 and on one side of the X-axis module 61 through a bracket. The material sensor 64 is used to sense whether there is a lens barrel on the lens barrel locking platform to ensure the normal operation of subsequent locking actions.

[0031] During implementation, the X-axis module 61 moves to deliver the platform containing the lens barrel to below the pressure ring suction pen 63. The Z-axis module 62 drives the pressure ring suction pen 63 to descend, pick up the inner pressure ring from the inner pressure ring locking platform, and then move it to directly above the lens barrel. By rotating and pressing down, the inner pressure ring is locked into the lens barrel.

[0032] Working principle: When in use, the lens barrel feeding mechanism 2 first transports the tray full of lens barrels to the picking position through the hopper lifting module 21 and the tray transfer module 23. The dual-axis manipulator 31 of the lens barrel loading mechanism 3 drives the cylinder gripper 32 to pick up the lens barrel from the tray and place it in the lens barrel locking platform on the X-axis module 61 of the locking mechanism 6.

[0033] Meanwhile, the flexible vibratory feeder 41 of the inner pressure ring feeding mechanism 4 vibrates and transports the inner pressure ring to the platform fixture 42, and the upper vision camera 43 takes pictures and positions the inner pressure ring in the platform fixture 42. The three-axis robot 51 of the inner pressure ring picking mechanism 5 drives the picking pen 52 to pick up the inner pressure ring according to the positioning information and moves it to the inner pressure ring locking platform on the X-axis module 61. Combined with the visual guidance of the positioning camera 53, the inner pressure ring is accurately placed on the platform.

[0034] Subsequently, the X-axis module 61 moves to deliver the platform containing the lens barrel to below the pressure ring suction pen 63. The Z-axis module 62 drives the pressure ring suction pen 63 to descend, pick up the inner pressure ring from the inner pressure ring locking platform, and then move it to directly above the lens barrel. By rotating and pressing down, the inner pressure ring is locked into the lens barrel.
