The transplanting module 3 includes a rotating unit 31, a turntable 32, and multiple positioning fixtures 33. The turntable 32 is detachably connected to the rotating unit 31. Multiple positioning fixtures 33 are mounted on the turntable 32, and each positioning fixture 33 is equipped with an information transmission unit 34. The turntable 32 is rotatably connected to the equipment table 13 via the rotating unit 31. As the turntable 32 rotates, the positioning fixtures 33 sequentially pass through the adhesive application and inspection station 21, the part removal and installation station A22, the screw fastening station 23, the part removal and installation station B24, and the screw fastening station 23. The information transmission unit 34 includes an RFID tag reader and RFID tags, enabling data exchange between each process. A preferred embodiment is that three screw fastening stations 23 are located between the part removal and installation stations A22 and B24, allowing for the sequential installation and fastening of three parts respectively.

[0025] like Figure 6As shown, the part-picking and installation station A22 includes a quick-change fixture A221 connected to a robotic arm. The quick-change fixture A221 is connected to the adsorption assembly A via a connecting bracket 222. The adsorption assembly A includes adsorption unit one 223, adsorption unit two 224, and adsorption unit three 225. Each of these units includes a spring plunger 226 and a suction cup 227.

The upper end of the electric screwdriver 239 is connected to the connecting plate 235, and the lower end passes through the lower end of the C-shaped plate 232 and is connected to the screw-attracting unit 230. This can also be understood as the linear slider 234, connecting plate 235, and connector 237 being connected together and moving along the linear track 233 with the linear slider 234. When the linear cylinder 236 extends, its telescopic end pushes the connector 237 downward, and simultaneously the linear slider 234 and connecting plate 235 move downward together, while the electric screwdriver 239 moves downward with the connecting plate 235. To ensure the stability of the electric screwdriver 239's movement, the connector 237 can be designed as an L-shape, with a spring 238 between the connector 237 and the upper end of the C-shaped plate 232. The telescopic end of the linear cylinder 236 is fitted inside the spring 238. Due to the elasticity of the spring 238, this makes the telescopic end of the linear cylinder 236 more stable when moving towards the nail-collecting unit 230.

The product station 337 has a component one station 338 and a component two station 339, where component one and component two are respectively placed in component one station 338 and component two station 339. The base 331 also has a metal knob 336, which is used to connect the base 331 to the turntable 32.

[0029] like Figures 2 to 5 As shown, in the assembly as Figure 1When using the lens module shown, this utility model device is employed. The device includes a device frame 1, an assembly module 2, and a transfer module 3. The device frame 1 mainly consists of a welded frame 11, a human-machine interface component 12, a device platform 13, and a safety protection 14. The welded frame 11 is mainly assembled from square tubing and sheet metal parts, and is used for the installation of the human-machine interface component 12, the device platform 13, and the safety protection 14, as well as the placement of electrical components. The human-machine interface component 12 is mainly assembled from a display, a touch screen, indicator lights, buttons, and a control box, and is used for setting device parameters, providing device status feedback, and switching between multiple product functions. The device platform 13 is mainly used for the installation of the assembly module 2 and the transfer module 3. The safety protection 14 is mainly assembled from a safety light curtain, an emergency stop button, and a two-hand start button to ensure that the device is locked during manual loading and unloading. The assembly module 2 sequentially includes an adhesive application and inspection station 21, a component removal and installation station A22, a three-screw fastening station 23, a component removal and installation station B24, and a screw fastening station 24. These structures are installed on the device platform 13. The adhesive application inspection station 21 mainly includes a dispensing valve 211 and a vision unit 212. The dispensing valve 211 is connected to a robotic arm. The adhesive application inspection station 21 is used for applying adhesive to the corresponding parts and for quality inspection of the adhesive application results. The robotic arm is designed to be programmed according to different parts. The transfer module 3 is mainly assembled from a rotating unit 31, a turntable 32, a positioning fixture 33, and an information transmission unit 34. These structures are installed on the equipment table 13. The rotating unit 31 is driven by a DD motor, and the turntable 32 is mounted on top of the rotating unit 31. The information transmission unit 34 includes an RFID tag reader / writer, RFID tags, and a mounting bracket, used for information transmission in each process. The positioning fixture 33 is mainly used to place the corresponding lens parts and component products, ensuring the placement posture meets the requirements of each process in the assembly module 2. The positioning connection between the positioning fixture 33 and the turntable 32 requires a metal knob 336 for easy switching between different products. Figure 5 As shown, the turntable 32 is equipped with eight positioning fixtures 33.

[0030] When using the equipment, the first step is for the employee to place the three parts required for the lens module 4, as well as component 1 41 and component 2 45, on the positioning fixture 33. The three parts are component 1 42, component 2 43, and component 3 44. Component 1 42, component 2 43, and component 3 44 are placed into the first part slot 333, the second part slot 334, and the third part slot 335, respectively. Component 1 41 and component 2 45 are placed into the component 1 station 338 and the component 2 station 339, respectively. The second step is to start the equipment with both hands, and the turntable 32 rotates one station. The employee continues to place the three parts, as well as component 1 41 and component 2 45, in the next positioning fixture 33. In the third step, when the first positioning fixture 33 carrying the parts moves to the glue application and inspection station 21, thermally conductive adhesive is applied to the part of component 1 41 where component 3 44 needs to be installed, and the process is inspected. In the fourth step, at the component removal and installation station A22, adsorption units 1 223, 224, and 3 225 respectively pick up the three parts and place them into the corresponding positions on component 1 41, with their respective spring plungers 226 ensuring accurate alignment. In the fifth step, at the screw fastening station 23, the three screw fastening stations 23 sequentially install the three types of parts onto component 1 41 using screws. In the sixth step, at the component removal and installation station B24, component 1 41 and component 2 45 are placed together, and two gripper units 240 are used to clamp component 1 41 and place component 2 45 into its position. In the seventh step, the positioning fixture 33 continues to rotate to the downstream screw fastening station 23, connecting component 1 41 and component 2 45 together to complete the assembly, followed by manual unloading. This cycle repeats, allowing the employee to complete lens assembly simply by removing the finished product and placing the parts again, requiring only one employee.

[0031] This invention integrates the various processes of lens module assembly, allowing one employee to complete operations at multiple workstations. Through modular design and rotary indexing, process integration is achieved. The turntable 32 integrates processes such as adhesive application inspection, component removal and installation A, screw fastening, and component removal and installation B, significantly reducing the equipment's footprint compared to a flat assembly line. Each workstation transmits product parameters via information transmission unit 34, and the robotic arm automatically calls the corresponding program. The positioning fixture 33 uses a quick-change metal knob, and the quick-change fixture base is also replaceable, enabling compatibility with multiple lens products. Compared to traditional production lines, this equipment reduces the number of operators, improves yield, and increases changeover efficiency; one machine can produce multiple products.
