Description
Technical Field
The utility model relates to a camera lens test positioner belongs to testing arrangement technical field.
Background
The camera lens assembly generally consists of a lens, a Sensor board (image Sensor board) mounted on the base by screws, and a mounting base to which the lens is connected by threads. In order to ensure the imaging quality of the camera, two key technical parameters need to be considered: the Sensor board mounting plane influences the scope of camera lens focusing distance to the distance of camera lens mounting plane, the straightness that hangs down of Sensor board mounting plane and camera lens mounting screw hole axis, and the former influences the scope of camera lens focusing distance, and the latter if the deviation is too big, will cause the unclear or marginal blurred problem about the image, greatly influences the installation and debugging efficiency of camera at the scene, even causes the unable normal formation of image of camera, consequently, is necessary to detect the roughness of camera lens before the camera dispatches from the factory.
At present, a commonly used method for detecting the flatness of a lens is to assemble a machine core and the lens, then install the machine core and the lens on a tripod, inspect the edge definition of an image by imaging and observing a definition test card, or automatically measure the resolution value of a camera by software, and then compare a measurement result with a visual evaluation result, thereby judging the flatness of the image. General camera is through the screw mounting on the fast-assembling board of tripod, fixes to on the tripod mounting platform again, and many times of dismouting probably causes the slight removal of tripod, leads to at every turn to install the back and need carry out the minizone adjustment to the camera lens to ensure that the scope of the definition test card that batch camera lens was shot is unanimous, and this process is comparatively complicated to extensive industrial production, and the operation is higher to the tester requirement of mill moreover, will influence production efficiency greatly.
SUMMERY OF THE UTILITY MODEL
In view of the foregoing prior art, an object of the present invention is to provide a camera lens test positioning device for solve the present camera lens roughness among the prior art and detect common method and assemble core and camera lens earlier, then install it on the tripod, through carrying out the formation of image observation to the definition test card, inspect image edge definition, also perhaps survey the resolution numerical value of camera through software is automatic, compare measuring result and visual estimation result again, thereby judge the image roughness. General camera is on the fast-assembling board of tripod through the screw installation, fixes to on the tripod mounting platform again, and many times of dismouting probably causes the tripod to slightly remove, leads to at every turn to install the back and need carry out the minizone adjustment to the camera lens to ensure that the scope of the definition test card that batch camera lens was shot is unanimous, and this process is to extensive industrial production, and the operation is comparatively complicated, and the requirement is higher to the tester of mill moreover, will influence production efficiency's problem greatly.

By adopting the technical scheme: when the camera lens is detected, the camera slides from one end of the opening of the outer frame to enter the inner part of the outer frame, and one end of each clamping block is inclined, so that when the camera enters the inner part of the outer frame, the two clamping blocks move towards two sides under stress, the gap between the clamping blocks is enlarged, the camera enters between the two clamping blocks, and the spring between the clamping blocks and the outer frame exerts force on the clamping blocks, so that the clamping blocks clamp the camera, and the camera is fixed.
In an embodiment of the present invention, the frame further includes a bottom plate, and the bottom plate is fixedly connected to the bottom of the outer frame.
By adopting the technical scheme: the stability of the positioning device is improved by arranging the bottom plate.
In an embodiment of the present invention, the bottom plate has a chute, and the bottom of the clamping block is connected to the chute of the bottom plate through the slider.
By adopting the technical scheme: when the clamping block moves, the sliding block is driven to move along the sliding groove, so that the moving direction of the clamping block is limited, and the clamping block is prevented from generating transverse displacement, and the clamping effect is poor.
In an embodiment of the utility model, the fixed block up end be provided with two telescopic cylinder, the clamp plate is connected to telescopic cylinder top.
By adopting the technical scheme: the telescopic cylinder drives the pressing plate to move up and down, when the camera is clamped inside the outer frame, the telescopic cylinder drives the pressing plate to descend, the camera is clamped in the vertical direction, and the fact that the camera is inaccurate in testing due to displacement in the vertical direction is avoided.
In an embodiment of the present invention, a contact sensor is disposed on a side of the fixing block connected to the outer frame.
By adopting the technical scheme: when the camera enters the inner part of the outer frame and contacts the contact sensor, the telescopic cylinder is triggered, and the telescopic cylinder drives the pressing plate to move to clamp the camera.
As above, the utility model discloses a camera lens test positioner has following beneficial effect:
the utility model discloses in realized the fixed to the camera through pressing from both sides tight piece, and press from both sides tight piece and can follow the slide rail and freely remove, can accurately fix a position the camera, all need artifical correction camera position when having removed the test at every turn from, improved the work efficiency that the camera lens detected, reduced operation personnel's intensity of labour, and positioner is applicable in the camera of various sizes, and application scope is wide, device simple structure, and is easy and simple to handle.
