[0021] like Figures 1-8 As shown, the embodiments of this utility model include:

[0022] A high-precision assembly device for mobile phone camera lenses includes a conveyor 1, an XY-axis linear module 2, a lens suction nozzle 3, and a hopper 4. The XY-axis linear module 2 is mounted directly above the conveyor 1, and the lens suction nozzle 3 is mounted on the XY-axis linear module 2. The hopper 4 is located outside the conveyor 1, and lens trays 5 are stacked inside the hopper 4. A transfer platform 6 is located outside the hopper 4 to dock with the lens trays 5. A traction support 8, supported on a rodless cylinder slide 7 and connected to the lens trays 5, is located between the transfer platform 6 and the hopper 4. A stop cylinder 9 and a lifting cylinder 10 are arranged along the conveyor 1. The lifting cylinder 10 is used to position the back cover of the mobile phone. The lens suction nozzle 3 is docked to the conveyor 1 and the transfer platform 6 respectively through the XY-axis linear module 2.

[0023] The XY-axis linear module 2 is equipped with a main backplate 11. The front of the main backplate 11 is provided with a Z-axis linear guide 12, and the back is provided with an electric Z-axis synchronous pulley set 13. The Z-axis linear guide 12 is provided with a lifting platform 14 mounted on the electric Z-axis synchronous pulley set 13. The lifting platform 14 is provided with a hollow rotating platform 15. The hollow rotating platform 15 is connected to a swing arm 16. The swing arm 16 is connected to a secondary backplate 17. The secondary backplate 17 is provided with a Z-axis sub-linear guide 18. The Z-axis sub-linear guide 18 is provided with a floating slider 19. The floating slider 19 is connected to a guide post 20. The guide post 20 is connected to a spring 21. The guide post 20 is connected to the swing arm 16. The swing arm 16 is provided with a pressure sensor 22. The floating slider 19 is connected to a lens suction nozzle 3.

[0024] Furthermore, the lifting platform 14 is provided with a downwardly arranged first visual positioning camera 23 at the center of the hollow rotating platform 15. The first visual positioning camera 23 is used to assist the hollow rotating platform 15 in correcting the assembly angle of the silkscreen on the lens. A second visual positioning camera 24 is externally mounted on the main back plate 11. The second visual positioning camera 24 is used to guide the positioning of the lens on the transfer platform 6 and the conveyor 1.

[0025] Furthermore, a shelf 25 is provided inside the hopper 4, and a stop pin 27 is passed through the side wall of the hopper 4. A return spring is sleeved on the stop pin 27. The inner end of the stop pin 27 is engaged with the shelf 25 to stop the lens tray 5. A guide pulley 29 is provided at the outer end of the stop pin 27. The guide pulley 29 is matched with a wedge block 31 driven by a cylinder 30.

[0026] Furthermore, the upper surface of the traction support 8 is provided with a traction positioning pin 32, the traction support 8 is supported on a lifting cylinder 33, the lifting cylinder 33 is installed on the rodless cylinder slide 7, and the lens material tray 5 is provided with a waist hole 34 matching the traction positioning pin 32.

[0027] Furthermore, the transfer platform 6 is composed of a pair of parallel vertical side plates 35. The top of the side plate 35 is provided with an upper limit stop bar 36. The bottom surface of the upper limit stop bar 36 is used to press the lens tray 5. A lifting and positioning cylinder 37 is provided directly below the upper limit stop bar 36. A transfer point positioning pin 38 is installed on the lifting and positioning cylinder 37. The bottom surface of the lens tray 5 is provided with a pin hole 39 that matches the transfer point positioning pin 38.

[0028] The conveyor 1 carries a carrier containing a mobile phone back cover into this equipment. The XY-axis linear module 2 drives the lens suction nozzle 3 to the transfer platform 6 to retrieve the camera lens. The retrieved lens undergoes positioning detection by a lower vision camera to identify its specifications and determine its mounting position on the mobile phone back cover. Then, the first vision positioning camera 23 identifies the silkscreen position on the lens, and the hollow rotating platform 15 corrects the lens's θ angle. The XY-axis linear module 2 then drives the lens suction nozzle 3 to a position directly above the conveyor 1, where the second vision positioning camera 24 moves the lens to the correct mounting position. Finally, the electric Z-axis synchronous pulley group 13 drives the lifting platform 14 downwards. After the lens suction nozzle 3 contacts the mobile phone back cover, the spring 21 compresses and buffers, pressing the lens into place to complete the assembly process.

[0029] This equipment is equipped with three hoppers 4, which store lenses of different specifications. The lens specifications can be determined according to the assembly process requirements. Lenses of the same type can be shared without stopping the machine through the XY two-axis linear modules 2. Different types of lenses are equipped with independent XY two-axis linear modules 2. As shown in the figure, this embodiment involves three hoppers 4, storing two types of lenses. Each type of lens is assembled by one XY two-axis linear module 2. After the lens suction nozzle 3 picks up the material, it will identify the lens specification to avoid incorrect part numbers in the hoppers 4.

[0030] The lens of conveyor 1 is also equipped with a pressure-holding station, which uses a screw lifting platform 14 to maintain the pressure of the assembled lens.

[0031] Next to this equipment is a passive roller conveyor with a high downstream and low upstream section. This equipment can use a robotic arm to send the assembled mobile phone back covers to the downstream station, while placing the empty carrier on this passive roller conveyor. The empty carrier slides back to the upstream feeding position under the action of gravity, which facilitates manual feeding.

[0032] In summary, this utility model provides a high-precision assembly equipment for mobile phone camera lenses. It uses a rodless cylinder slide 7 to drive a traction support 8 to achieve automatic feeding of the lens tray. It also integrates a visual positioning camera onto the lens suction nozzle 3 through a hollow rotating platform 15 to solve the purpose of correcting the lens screen printing angle, thereby effectively improving the lens assembly efficiency and the quality control effect of screen printing assembly.
