For this reason, the utility model terminal height difference detector adopts following technical scheme:
Structure the utility model terminal height difference detector comprises movable platform, laser projections system, camera system, PC industrial computer or ordinary PC and has the controller of data processing function that movable described platform has places to be detected station; The laser projections system is arranged on the top of movable described platform, and its laser can project the described station of to be detected of placement; Camera system be arranged on movable described platform directly over, can accept to be positioned to be detected optical information of the described station of movable described platform; Camera system is converted to electrical information with optical information and imports controller and carry out data processing, and the output interface of controller connects PC industrial computer or ordinary PC; PC industrial computer or ordinary PC connect movable described platform by motion control unit, to control the motion of described platform, to obtain to be detected three bit images and to be converted to corresponding data.
Technique scheme is described further:
The laser beam of described laser projections system is split into a laminar light beam by fan and becomes miter angle to project on to be detected.
Described laser projections system comprises lasing light emitter, light projector mirror group, glass raster, telecentric lens and A polarizing board, and installs successively.
Described camera system comprises CCD, telecentric lens and B polarizing board, and installs successively.
Working mechanism of the present utility model or detection method of the present utility model are described as follows:
Laser beam is split into a laminar light beam by fan and becomes on the miter angle projection terminal, on terminal, manifest then be one continuously or the bright light rays of stair shape, can be accepted by the top camera system and calculate by controller, from the bright line that is recorded, can once obtain the profile information of the two-dimensional directional on this optical section, just can obtain to be detected 3-D view by the motion of platform.
The utility model is compared with prior art, has adopted the mode of laser measurement to obtain the mode that image combines the color 2 D graphical analysis simultaneously again, is using and detection mode is all innovated to some extent and broken through.Its beneficial effect is:
One, and deposit 3D and 2D measuring function, the height measuring accuracy is up to 0.005mm.
Its two, on-line measurement, effectively management and control procedure for producing.
Its three, need not manual intervention, finish multinomial order automatically and measure, and reject bad product.
Its four, simple in structure, be convenient to implement.
Its five, of many uses, except that the detection that is used for terminal, the suitable especially other products that the height or the degree of depth of product are had measurement requirement.
