随着新能源汽车的发展,越来越多人关注并购买。而新能源汽车在生产制造过程中会配有许多微型电机,这些微型电机定子的检测就可能需要用到工业内窥镜。目前市面上大多工业内窥镜视场角大于100°,虽然视场角增大有利于提高观测范围,但畸变也会越大,后续的图像处理就越复杂,对于微型电机定子而言,内部空间狭窄且为管道结构,所需观测范围不大,因此不适用于对其的检测。文章设计了一种专用于微型电机定子内部检测的工业内窥镜光学系统,其视场角为64°,搭配20mm的工作距离,所具有的观测范围恰好能覆盖内部整体空间。该设计由6块球面镜组成,制造成本低
整个光学系统总长为60mm
焦距为3.99mm,F数为3.3,畸变大于-20%,相对照度接近1,在奈奎斯特频率105lp/mm处,所有视场的调制传递函数均大于0.65。经过图像模拟,整体成像质量较好。最后由公差分析结果表明,该系统结构合理,满足生产要求,同时对新能源汽车的发展具有一定意义。
With the development of new energy vehicles
more and more people are paying attention to and purchasing them. During the production process of new energy vehicles
many micro motors are used
and the inspection of the stators of these micro motors may require the use of industrial endoscopes. Currently
most industrial endoscopes on the market have a field of view greater than 100°
which
while increasing the observation range
also increases distortion
making subsequent image processing more complex. For micro motor stators
the internal space is narrow and has a conduit structure
so a large observation range is not required
hence it is not suitable for such inspections. This article designs an optical system for an industrial endoscope specifically for the internal inspection of micro motor stators
with a field of view of 64° and a working distance of 20mm
providing an observation range that perfectly covers the entire internal space. The design consists of 6 spherical mirrors
resulting in low manufacturing costs. The total length of the optical system is 60mm
with a focal length of 3.99mm and an F-number of 3.3. The distortion is greater than -20%
and the relative illumination is close to 1. At the Nyquist frequency of 105lp/mm
the modulation transfer function for all fields of view is greater than 0.65. Image simulation shows that the overall image quality is quite good. Finally
tolerance analysis indicates that the system structure is reasonable and meets production requirements
which is also significant for the development of new energy vehicles.
