Abstract
The invention relates to a light source system for visual inspection of a green vial machine. At a vial bottom inspection station, the vial bottom of a green vial is upward; four green light sources are placed over the vial bottom in a surrounding manner; the four green light sources define a rhombus to form a light source for vial bottom inspection; at a vial opening inspection station, a green annular light source is placed over a vial opening as a light source for vial opening inspection; at a vial body inspection station, a white coaxial light source is placed right ahead a vial body; the center of the coaxial light source is located on an optical axis of a camera. According to the system, the light sources and lighting modes suitable for parts of the vial are selected according to the characteristics of the parts of the vial, and a good effect is obtained.
Description
Technical field
The invention belongs to medical production industry, the main defect detecting green phial.
Technical background
In view of the feature of medical industry, at the beginning of this detection design, just focus on very much degree of accuracy and the stability of detection.This green phial itself is very little, and each face produced problem is all different again, and the feature of detection is also different.This green bottle encounters a very large difficult problem in context of detection.In order to solve this difficult problem, polishing is crucial.Can the software after its quality directly determines accurately detect.
Summary of the invention
In view of the above problems, the object of this invention is to provide a kind of light-source system that precisely can detect the green phial Machine Vision Detection of the condition providing good for image afterwards.This invention is realized by following techniques and methods:
A kind of green phial Machine Vision Detection light-source system, be the gengon shape of having edges and corners at the bottom of the bottle of green phial, comprise test light source at the bottom of empty bottle inspection light source, bottle and body test light source, station is detected at the bottom of bottle, at the bottom of green bottle bottle upwards, around placement four green bar radiants (3) directly at the bottom of bottle; Four green bar radiants surround rhombus, form test light source at the bottom of bottle, the optical axis coincidence of the center of rhombus and the line at Ping Di center and camera (21) camera lens; At empty bottle inspection station, directly over bottleneck, place a green annular light source, as empty bottle inspection light source, bottleneck center and green are positioned on camera (22) camera lens optical axis; Detect station at body, place a white coaxial light source in the dead ahead of body, on the optical axis being centrally located at camera (23) of coaxial light source.
Green phial Machine Vision Detection light-source system of the present invention, by at the bottom of bottle, select different colours different types of light source when bottleneck and body detect, complete and take pictures to green phial is omnibearing, provide good condition for image afterwards precisely detects.
Accompanying drawing explanation
Fig. 1. be polishing figure at the bottom of the bottle of green phial Machine Vision Detection
Fig. 2. be the bottleneck polishing figure of green phial Machine Vision Detection
Fig. 3. be the body polishing figure of green phial Machine Vision Detection
Description of reference numerals is as follows:
1 green phial; 21,22 and 23 be respectively at the bottom of shooting bottle, the camera of bottleneck and body; 3 green strip sources; 4 green annular light sources; White coaxial light source
Embodiment
Below in conjunction with accompanying drawing and example, the present invention is further elaborated.
By reference to the accompanying drawings 1, polishing mode at the bottom of the bottle of green phial 1 Machine Vision Detection is described down.The bottle end, is detected, no clear when mainly detecting character at the bottom of bottle, has inviolateness.In view of at the bottom of bottle not on a plane, be a gengon of to have edges and corners, require that each face has illumination to arrive, whole bottom surface is without dead angle, not reflective.So take four bar light 3 at a certain angle according to each ground, side at the bottom of bottle, the polishing mode of the same perpendicular line in rhombus center that camera 21 center and four green bar light surround, green glow shines green medicine bottle can filter many interference.
By reference to the accompanying drawings 2, the bottleneck polishing mode of green phial Machine Vision Detection is described down.Empty bottle inspection, whether damagedly mainly detect bottleneck, whether bottleneck has burr.In view of the circle that bottleneck is rule, so take circular rings light 4 to be vertically fixed on mode polishing above bottleneck, be also green light source.
By reference to the accompanying drawings 3, the body polishing mode of green phial Machine Vision Detection is described down.Body detects, and main icon and the character detecting medicine bottle right opposite, little side has inviolateness, stain.In view of the importance of body icon and character, to prevent the reflective of little side from impacting front character machining through test.So take axis light to be fixed on body front illuminated, camera 23 and axis light center 5 place are point-blank, better by white light irradiating and detecting effect.
In sum, green phial Machine Vision Detection light-source system of the present invention, by selecting the LED of different colours, the polishing mode of different angles, the reflection of light, the principles such as diffraction, complete and take pictures to medicine bottle is omnibearing, have very crucial effect to the accurate detection of software.
Claims (1)
1. a green phial Machine Vision Detection light-source system, be the gengon shape of having edges and corners at the bottom of the bottle of green phial, comprise test light source at the bottom of empty bottle inspection light source, bottle and body test light source, it is characterized in that, station is detected at the bottom of bottle, at the bottom of green bottle bottle upwards, around placement four green bar radiants (3) directly at the bottom of bottle; Four green bar radiants surround rhombus, form test light source at the bottom of bottle, the optical axis coincidence of the center of rhombus and the line at Ping Di center and camera (21) camera lens; At empty bottle inspection station, directly over bottleneck, place a green annular light source, as empty bottle inspection light source, bottleneck center and green are positioned on camera (22) camera lens optical axis; Detect station at body, place a white coaxial light source in the dead ahead of body, on the optical axis being centrally located at camera (23) of coaxial light source.
