Technical Field
The utility model relates to a camera lens production technical field, especially single anti-camera lens's check out test set.
Background
Single Lens reflex, which is the most popular viewing system today, is referred to as single Lens reflex, and most 35mm cameras use such a viewfinder. In such systems, the unique design of the mirrors and prisms allows the photographer to view the image through the lens directly from the viewfinder. In the slr, a lens is an important component, and after the lens is produced, a lot of key information is printed on the periphery of the lens. However, in the prior art, various defects such as missing printing, local darkness of diffraction, dirt, oblique deformation of patterns and the like can be caused after the product is formed due to errors of printing equipment, misoperation of workers, damage of mounted tooling fixtures and the like in the printing process.
At present, the visual inspection of the lens is judged by naked eyes of people, but because the information on the periphery of the lens is more and the font is smaller, the judgment is not good when people inspect the lens, or the inspection is missed due to fatigue of people. In the prior art, the technology for recognizing images is mature, but no equipment can apply the technology to the inspection of the appearance of the periphery of the lens, so that an inspection equipment which can comprehensively and automatically inspect the periphery of the lens is needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: an apparatus for inspecting an outer peripheral appearance of a lens using an image recognition technique is provided.
The utility model provides a solution of its technical problem is: lens all around visual inspection device, including the frame, the frame includes the workstation, be equipped with on the workstation and put thing seat, image shooting mechanism includes the camera, the camera is facing to putting the thing seat, still include actuating mechanism in the frame, actuating mechanism drives and puts thing seat and be rotary motion relatively the workstation.
The utility model has the advantages that: the utility model discloses an utilize actuating mechanism to drive and put the thing seat and rotate, then shoot the mechanism by the image and shoot the whole week outward appearance of the thing of being examined on putting the thing seat, then compare the image that will shoot down with predetermined image, whether the whole week outward appearance that utilizes image recognition technology to judge the camera lens prints clearly, errorlessly.
As a further improvement of the above technical scheme, the object placing seat comprises a connecting sheet, the bottom of the connecting sheet is detachably connected with the object placing seat, and a lens clamping groove is formed in the top of the connecting sheet. Because the lens mounting structures of different single lens reflex manufacturers are different in the existing lens, the connecting sheet can be compatible with the lens mounting structures of different manufacturers.
As a further improvement of the above technical solution, the image capturing mechanism includes a linear CCD. By utilizing the linear CCD, the shot picture can be clearer, and the method is more suitable for shooting the periphery development image.
As a further improvement of the technical scheme, the driving mechanism comprises a pulse motor and a speed reducer, a main shaft is arranged in the object placing seat, and the main shaft is in driving connection with the pulse motor through the speed reducer. By adopting the mechanism, the object placing seat can rotate more smoothly.
As a further improvement of the technical scheme, the frame further comprises an electric sliding table, and the image shooting mechanism is installed on the electric sliding table. The electric sliding table can be matched with the electric sliding table moving along the X/Y axis, so that the position of the image shooting mechanism can be adjusted, and measured objects with different sizes can be conveniently detected.
As a further improvement of the above technical scheme, a vertical plate is further arranged on the frame, the vertical plate is mounted on the workbench, a slide rail is arranged on the vertical plate, the slide rail moves up and down, a moving mechanism is arranged on the slide rail, a light source is arranged on the moving mechanism, and the light source is close to the object placing seat. The position of the light source relative to the object placing seat can be adjusted by utilizing the movement mechanism, so that the light source can correspond to different light darkness degrees of the surface of the object to be measured. Meanwhile, the vertical plate is higher than the height of the object to be detected, so that the interference of external light can be reduced by adding the vertical plate.
