Description
Technical field
The utility model belongs to machine vision illumination technical field, is specifically related to a kind of two-way linear illuminator.
Background technology
In the field of illumination systems of field of machine vision, usually three kinds of lighting systems are had, coaxial-illuminating, offside reflection is thrown light on, and transillumination, and in offside reflection lighting engineering, the most frequently used is the illumination of single lit sideways at present, optical fiber front end adds cylindrical lens, the CCD received is placed on the other side of illumination, and such illuminator can be applied in the Defect Detection of detection plate level, but if testee has height, so the other side of testee just there will be shade, and such situation can directly cause last measuring accuracy not high.And because the receiving traps such as CCD are also tiltedly put, the volume of last whole board can be caused like this to increase, make troubles to use.
Utility model content
For prior art Problems existing, the purpose of this utility model is to design the technical scheme providing a kind of two-way linear illuminator.
Described two-way linear illuminator, comprise light source stationary housing, it is characterized in that described light source stationary housing symmetria bilateralis arranges the first lighting fiber and the second lighting fiber, logical light groove is provided with in the middle part of described light source stationary housing, place measured object immediately below described logical light groove, the second reflective mirror and the second spill cylindrical mirror that the emergent light of the first lighting fiber can be reflexed to the first reflective mirror of measured object and the first spill cylindrical mirror and the emergent light of the second lighting fiber can be reflexed to measured object are set in described light source stationary housing.
Described two-way linear illuminator, is characterized in that the first described lighting fiber and the second lighting fiber are rotatably assorted in light source stationary housing.
Described two-way linear illuminator, it is characterized in that the first described spill cylindrical mirror and the second spill cylindrical mirror symmetry are fixedly installed on logical light groove both sides, and the concave reflective of the first spill cylindrical mirror and the second spill cylindrical mirror faces down.
Described two-way linear illuminator, it is characterized in that the lower right of the first described spill cylindrical mirror is equipped with the first reflective mirror, the lower left of the second described spill cylindrical mirror is equipped with the second reflective mirror.
Above-mentioned two-way linear illuminator, reasonable in design, structure is simple, substantially reduces the volume of equipment, and no matter whether testee has height, and whether surface has unequal edge problem, and it is very clear and even that this system edge profile can both irradiate.

Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As described in Figure, two-way linear illuminator comprises light source stationary housing 1 and is arranged on lighting fiber, spill cylindrical mirror and the reflective mirror in light source stationary housing 1.Being provided with logical light groove 5 in the middle part of light source stationary housing 1, for placing measured object 6 immediately below logical light groove 5, directly over logical light groove 5, being equipped with imaging lens 7 and CCD8.Lighting fiber comprises the first lighting fiber 401 and the second lighting fiber 402 being symmetricly set on light source stationary housing 1 both sides, first lighting fiber 401 and the second lighting fiber 402 are specifically rotatably assorted with light source stationary housing 1, and therefore the angle of the first lighting fiber 401 and the second lighting fiber 402 can regulate.Spill cylindrical mirror comprises the first spill cylindrical mirror 201 and the second spill cylindrical mirror 202 being symmetricly set on logical light groove 5 both sides, and the concave reflective of the first spill cylindrical mirror 201 and the second spill cylindrical mirror 202 faces down.Reflective mirror comprises the second reflective mirror 302 being arranged on bottom-right first reflective mirror 301 of the first spill cylindrical mirror 201 and being arranged on the second spill cylindrical mirror 202 lower left.The emergent light of the first lighting fiber 401 can be reflexed to measured object 6 by the first reflective mirror 301 and the first spill cylindrical mirror 201, and the emergent light of the second lighting fiber 402 can be reflexed to measured object 6 by the second reflective mirror 302 and the second spill cylindrical mirror 202.
During work, first lighting fiber 401 of the left and right sides and the second lighting fiber 402 send light beam, be irradiated on the first reflective mirror 301 and the second reflective mirror 302 respectively, light beam reflexes on the first spill cylindrical mirror 201 and the second spill cylindrical mirror 202 by the first reflective mirror 301 and the second reflective mirror 302 respectively, light beam draws in and converges by the first spill cylindrical mirror 201 and the second spill cylindrical mirror 202, and be radiated on measured object 6, first lighting fiber 401 and the removable certain scope of the second lighting fiber about 402, regulate the size in convergence face, to ensure that measured object 6 can be irradiated to completely, illuminated scope is substantially at about 3mm, afterwards, choose imaging lens 7 as required, imaging lens 7 receives the optical fiber of measured object 6, and converge and be imaged onto on CCD 8.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
