Arrange into it is coniform testee surface is radiated at oblique angle, a small region is illuminated by diffusing reflection mode, operating distance is in 10-
During 15MM, the light source can highlight the change of testee edge and height, and the prominent part for being difficult to see clearly originally, is side
Edge detection, the ideal chose carved characters with damage check of metal surface.
Two strip sources are parallel when bar shaped combined light source uses two strip sources installs, and constitutes parallel bar shaped combination
Light source；Using triangularity light source during three strip sources, square light source is constituted during using four strip sources, using five bars
Regular pentagon bar shaped combined light source is constituted during shape light source.
Extended loop is to ensure different FOV（The angle of visual field）Adapt to different materials.
Shading ring is in order to avoid ambient light is disturbed, it is ensured that image brightness uniformity.
Sliding block and guide rail are used for the position for adjusting camera, conveniently reach optimal imaging effect.
Polarizer and polariscope reduce and eliminated the reflective of luminous object surface.
Light source assembly irradiates two relative sides of testee respectively, the side of upper camera calibration testee, i.e., just
Face, the light that the head-on reflection of testee goes out is imaged on by lens focus on the sensitive chip of upper camera, so as to form quilt
Survey the direct picture of object；Lower camera detects the opposite side of testee, the i.e. back side, the light of light source assembly by reflection subassembly
The back side of testee is irradiated to, the light that testee is reflected reflexes to lower camera by two pieces of reflex blocks being symmetrically installed
Lens focus, on the sensitive chip for being then imaged on lower camera, so as to form the back side image of testee.
Mechanism installing space is small, and installation and debugging are convenient, and double camera single-station positive and negative vision inspection apparatus is anti-by prism
Penetrate imaging to observe reverse side, front is observed by direct capture, while the front and rear relative two sides of testee is detected, so that
Can be with sufficiently effective saving mechanism space, while meeting Product checking demand.Each type objects of detection, bag can be widely used in
Include but be not limited only to：Semiconductor product such as IC components, discrete component, photoelectric cell, memory etc., and machining
Part, product of rubber and plastic, glassware etc.；It can be widely applied to different field, such as industrial production, food processing, automobile making, thing
