The lens selection is comprehensively considered according to the sensor size of the camera, the support interface form, the dial size of the detected pressure gauge, and the like. The imaging of the lens should be able to completely cover the sensor surface of the lens; the form of the connecting interfaces of the lens and the camera should be the same as much as possible; the field of view and depth of field of the lens should meet the dimensional requirements of the part being measured. The following is an explanation of several main parameters of the lens;
the field of view is the range of object sizes that the entire system can view, i.e., the size of the scene corresponding to what is called an image on the image sensor.
Working distance: the working distance is the object distance, namely: distance of the object to the lens.
Resolution ratio: resolution it is described that the distance of the smallest object that the optical system can resolve is generally calibrated by using a black and white line , namely: every millimeter of wire pairs (1 plmm).
Depth of field: the image of the stop or movement of the object in the direction of the optical axis is clear within a certain range, that is, this range is called depth of field.
An aperture: during this transmission not all light entering the system will eventually pass, but some of it will be blocked. In order to adjust the intensity of transmitted light, an aperture, that is, a circular hole with a variable diameter formed by a multi-blade mechanical device is generally arranged in the lens, and the diameter of the hole can be continuously changed during adjustment, so that the effective light inlet amount of the lens is changed. The size of the lens aperture is generally indicated by an F-number.
F number: assuming that the effective aperture of the optical system is d and the focal length is F, f=f/d. This parameter describes the lighting power of the optical system. The larger the effective aperture, the more light can be collected and passed, and the shorter the focal length, the greater the likelihood that the light will reach the imaging sensor.
The utility model selects the double telecentric lens with higher cost performance, and the main performance parameters are shown in table 1: the lens is matched with a camera by adopting a C-shaped interface. The imaging size meets the CMOS sensor size requirements of the camera. In addition, the lens has higher resolution and is suitable for high-precision size detection. The aperture and the focal length can be automatically adjusted to meet the requirements of the scheme.
The main support of the fixed frame support is processed by profile steel, high-precision numerical control processing is performed, screw holes are pre-opened, and other parts can be fixed through screws during later assembly.
The motion controller is responsible for z, y direction movement of the lens, serving the software imaging function. The motion controller is the core of motion control, the actuating mechanism is a stepping motor, a precise lead screw and a precise guide rail, and the feedback of the motion position depends on a high-precision grating ruler.
The parameters of the motion controller are shown in table 2:
the lens can move in the z-direction and the y-direction, the movement direction is controlled by a movement controller, and the movement precision is controlled by a stepping motor and a grating ruler.
The transmission part is used as a device for transmitting power and motion, and the manufacturing precision of the transmission part has great influence on the precision of the system. The ball screw transmission has the advantages of small friction loss, high transmission efficiency, small friction resistance, stability, no creeping and the like, and is widely applied.
The HJG-S precise ball screw adopted by the object stage is precisely ground, tightly assembled and strictly detected, and can ensure good motion precision and repeated positioning precision. The ball screws of HJG-S2505-3 are adopted on the X and Y axes of the object stage, the precision of the ball screws can reach 3-level precision according to the standard of national standard GB/T17587, the specific index is that the allowable stroke variation amount in 2 pi strokes is 12 mu m, the allowable stroke variation amount in 300mm strokes is V300P 12 mu m, the allowable stroke variation amount in effective strokes is Vup 12 mu m, and the target stroke tolerance ep is 8 mu m.
The ball screw and grating scale parameters are shown in table 3:
it is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
