The assembly component 20 is divided into two groups and is symmetrically arranged on the workbench 10. The group includes a lens barrel feeding mechanism 21, a component feeding mechanism 22 and a material taking mechanism 23. The lens barrel feeding mechanism 21 is provided with a lens barrel material tray 211, and the lens barrel is placed in the lens barrel material tray 211. The component feeding mechanism 22 is provided with a component material tray 221, and the component material Components are placed in the tray 221, and the material picking mechanism 23 transfers the components in the component tray 221 to the lens barrel on the lens barrel tray 211 for installation; the detection component 30 includes a support frame 31 and an upper visual mechanism 32, the support frame 31 is mounted on the workbench 10, the upper visual mechanism 32 is located above the lens barrel tray 211 and is slidably connected to the support frame 31, and the upper visual mechanism 32 moves between the two groups of lens barrel feeding mechanisms 21 and takes pictures of the lens barrel to determine its center position.

[0032] The assembly components 20 are two groups and are symmetrically arranged on the workbench 10, and the two groups of components can be respectively processed and assembled at the same time. The upper visual mechanism 32 is located above the lens barrel material tray 211 and is slidably connected to the support frame 31. The upper visual mechanism 32 moves between the two groups of lens barrel feeding mechanisms 21 and takes pictures of the lens barrel to determine its center position. The double-station lens assembly machine in the present application can be processed and assembled at two stations at the same time, and the assembly processing efficiency is higher, which greatly improves the assembly efficiency of the lens. At the same time, a detection component 30 is used to detect the position of the two groups of assembly components 20, so that the efficiency of the detection component 30 is maximized, reducing the overall cost of the lens assembly machine.

[0033] Specifically, the upper visual mechanism 32 includes a CCD camera 321, a longitudinal movement module 322 and a transverse movement module 323. The CCD camera 321 is located above the lens barrel tray 211 and is arranged on the longitudinal movement module 322.

The transverse movement module 323 is slidably connected to the support frame 31, and the transverse movement module 323 drives the longitudinal movement module 322 to move laterally. In order to facilitate CCD photography, a light source 324 is fixed in the direction of the CCD camera 321 for lighting. The detection component 30 also includes a lower visual mechanism 33, which is arranged on the workbench 10, and the lower visual mechanism 33 is located on one side of the component tray 221. The lower visual mechanism 33 takes pictures of the position of the component tray 221. In this embodiment, the structure of the lower visual mechanism 33 is similar to that of the upper visual mechanism 32, so it is not repeated here. After the upper visual mechanism 32 takes a picture of the lens barrel to be assembled, it transmits the position image information of the lens barrel to the control system. After the lower visual mechanism 33 takes a picture of the component, it transmits the image information of the component to the control system. After the control system obtains the center position information of the lens barrel and the center position information of the component based on the two types of image information, it controls the suction pen motion module 231 to move to the center of the component and the center of the lens barrel according to the two center position information, thereby improving the assembly accuracy.

[0034] Furthermore, the material taking mechanism 23 includes a suction pen motion module 231 and a suction pen storage 232. The suction pen motion module 231 can transfer the components in the component material tray 221 to the lens barrel on the lens barrel material tray 211 for installation. The suction pen storage 232 is located on one side of the component feeding mechanism 22. The suction pen motion module 231 moves to the suction pen storage 232 to replace the suction pen. Since the interior of the lens is assembled in a certain order by the lens, the spacer, the film holder and the film, different suction pens need to be used when sucking different components, so the suction pen needs to be replaced through the suction pen storage 232.

[0035] Specifically, the lens barrel loading mechanism 21 includes a lens barrel transfer module, a lens barrel material tray 211 is arranged on the lens barrel transfer module, and the component loading mechanism 22 includes a component transfer module, and a component material tray 221 is arranged on the component transfer module.

The suction pen movement module 231 includes a mounting head 2311, and the suction pen library 232 includes a base 2321 and a card plate 2322. The base 2321 is provided with a accommodating cavity 2323, and a suction pen is placed in the accommodating cavity 2323. A card plate 2322 is provided above the accommodating cavity 2323, and the suction pen can be removed from the mounting head 2311 after the card plate 2322 moves. In this embodiment, the card plate 2322 is provided with a clearance hole 2324 and a clamping hole 2325, and the clamping hole 2325 is connected with the clearance hole 2324, and the clearance hole 2324 and the clamping hole 2325 enclose a gourd-shaped hole. The aperture of the clearance hole 2324 is not less than the aperture of the accommodating cavity 2323, and the aperture of the clamping hole 2325 is less than the aperture of the accommodating cavity 2323. When the suction pen needs to be replaced, the installation head 2311 with the suction pen is first moved into the empty accommodating cavity 2323, and the card plate 2322 moves to block and intercept the suction pen. At this time, the installation head 2311 is lifted and the suction pen is removed, and then the installation head 2311 moves to the designated accommodating cavity 2323 and installs the designated suction pen.

[0036] Furthermore, the suction pen motion module 231 also includes an upper visual module 2312, which is located on one side of the mounting head 2311, and the upper visual module 2312 takes a picture of the position of the suction pen library 232. In this embodiment, the overall structure of the upper visual module 2312 is similar to the structure of the upper visual mechanism 32, so the specific structure of the upper visual module 2312 is not repeated. After the upper visual module 2312 takes a picture of the position of the suction pen on the suction pen library 232, the position image information of the suction pen is transmitted to the control system, and according to the central position information of the suction pen in the suction pen library 232, the suction pen motion module 231 is controlled to move to face the center of the accommodating cavity 2323 of the suction pen, thereby improving the accuracy of the assembly and replacement of the suction pen.

[0037] Furthermore, the material taking mechanism 23 further includes a crossbeam slide rail 233 , which is mounted on the support frame 31 , and the pen suction motion module 231 is slidably connected to the crossbeam slide rail 233 .

[0038] Specifically, the support frame 31 includes two support legs and a detection rail 311, the detection rail 311 is mounted on the two support legs, and the upper visual mechanism 32 is arranged on the detection rail 311 and slides on the detection rail 311. The beam rail 233 is also mounted on the support legs, the beam rail 233 is located below the detection rail 311, and the beam rail 233 is parallel to the detection rail 311. The beam rail 233 is staggered with the upper visual module 2312 to prevent the beam rail 233 from blocking the upper visual module 2312 from taking pictures. The pen suction motion module 231 also includes a lateral movement module 2313 and a longitudinal movement module 2314, and the lateral movement module 2313 is arranged on the beam rail 233 and is slidably connected to the beam rail 233. The longitudinal movement module 2314 is arranged on the lateral movement module 2313 and moves synchronously with the lateral movement module 2313. The longitudinal moving module 2314 is provided with the mounting head 2311, and the longitudinal moving module 2314 can drive the mounting head 2311 to move in the vertical direction. The upper visual module 2312 is also fixed to the transverse moving module 2313, and the upper visual module 2312 is located on one side of the longitudinal moving module 2314, and the upper visual module 2312 also moves synchronously with the transverse moving module 2313.

[0039] In this embodiment, two groups of symmetrical assembly components 20 are provided, so that the lens can be processed and assembled at the same time, and the assembly processing efficiency is higher, which greatly improves the assembly efficiency of the lens. At the same time, a detection component 30 is used to detect the positions of the two groups of assembly components 20, so that the efficiency of the detection component 30 is maximized, and the overall cost of the lens assembly machine is reduced.
