Similarly, the optical detection system of the imaging structure mainly comprises a light source 701, a lens 702 and a camera 703, the whole optical detection system is fixed on a Z-direction adjusting part 704, similarly to the direct-type imaging structure 600, the Z-direction adjusting part 704 is mainly an adjustable lens for compensating the position of the camera 703 in the Z direction and adapting to different depth of field requirements, and the whole optical detection system is mounted on a Y-direction adjusting part which is mainly used for compensating possible offset of the camera 703 in the Y direction.

Further referring to fig. 13 and 14, more specifically, the lens assembling apparatus of the present invention adds such an optical detection system to complete the function of detecting defects of the lens and/or the lens holder on the basis of automatically assembling the lens product, thereby ensuring the product yield of the subsequent assembling process. In the embodiment of the present invention, the optical detection system is used to perform the detection actions on the lens and the lens holder through the assembling method to embody in detail:

after the lens material tray and the microscope base material tray are respectively loaded into the respective corresponding portable bins to complete the loading, the lens material tray and the microscope base material tray are respectively transmitted to the lens transportation platform 100 and the microscope base assembly platform 200 under the driving of the motor mechanism by being installed on the respective bin bottom plates.

The lens tray and the lens holder tray are respectively clamped by the corresponding assembly platform and transferred to the corresponding material suction position of the cross beam type assembly structure 500.

In this transportation process, the direct-type camera 600 performs photographing positioning and optical recognition on the lens elements carried in the lens trays, identifies the lenses in the trays that are not point-marked (or generally called "dotting") (that is, the dotted trays are not transported to the beam assembly structure 500 for assembly), positions the lenses, and then performs fine adjustment on the assembly platform on the lens transport structure 300 through the light source detection system.

The double-mover motor 501 on the beam assembly structure 500 mechanically moves to a position right above the lens tray to perform the lens sucking action. Meanwhile, when the mirror base tray is transported on the mirror base transportation structure 400, the direct type photographing structure 600 mechanically performs positioning photographing and position compensation on the mirror base tray.

After the material suction action is completed, the double-rotor motor drives the material suction structure 502 to mechanically move to the position above the straight upper shooting structure 700 between the lens transportation structure 300 and the lens base transportation structure 400 so as to perform positioning shooting on the lens and perform position compensation. Then, the assembly platform carries the lens to mechanically move to the upper part of the lens base assembly platform 403 to assemble the lens to the lens base;

after the lens base on the entire lens base tray is completely assembled, the lens base tray is automatically transported to the second portable bin 201 by the lens base transporting structure 400, and the next lens is assembled to the lens base tray.

After the entire second portable bin 201 is filled with the assembled microscope trays, the sensing sensor 206 can sense that the set threshold has been exceeded and generate an electrical signal to remind the user of blanking.

On the basis of the above-described embodiments, a lens assembling apparatus assembly 800 may be provided. As shown in fig. 15, the exemplary main frame structure of the equipment assembly can be mainly divided into an upper frame and a lower frame spliced with the upper frame, and the lower frame is composed of a square steel frame 804 (which may include a sheet metal frame structure, for example). At the bottom of the lower housing are mounted casters/feet 806 for stationary and mobile handling of the equipment. Preferably, the upper frame is mainly composed of an aluminum frame (for example, an acrylic plate may be inserted) 805. The display 802 is installed on the front part of the upper frame, and the operation buttons 803 are installed on the front part of the lower frame corresponding to the display. Safety warning lamps 807 are respectively installed on two sides of the top of the equipment, and an FFU 801 is installed on the top of the equipment and used for preventing external dust from entering the equipment.
