Rear side, i.e. camera trigger switch 4 are fixed on a side arm 801 of a font support 8, and
To ensure that examined object 2 can be triggered successfully by camera trigger switch 4, camera triggering is opened
The vertical distance closed between 4 and the upper surface of transmission platform 1 is as far as possible small, and camera triggering is opened
Upper surface of 4 outlines higher than transmission platform 1 is closed, to meet to highly less examined object
Carry out the distance between upper surface of bar code identification, i.e. camera trigger switch 4 and transmission platform 1
More than or equal to 0, after examined object 2 first passes through height finder structure 3, then by trigger switch,
Camera trigger switch 4 is optoelectronic switch, optoelectronic switch transmitting light, when examined object 2 is passed through
The light of optoelectronic switch transmitting is touched when crossing optoelectronic switch, optoelectronic switch is triggered, so that line
Array camera 6 carries out identification of taking pictures to the bar code in examined object 2.
When using, examined object 2 is placed on transmission platform 1, and ensures thing to be detected
Upward, transmission platform 1 is moved the bar code of body 2 under the driving of drive mechanism, so that band
Dynamic examined object 2 is moved, and examined object 2 first passes through height finder structure 3 in moving process,
The height of examined object 2 is detected, the elevation information of detection is passed to mould by height finder structure 3
Group 7, module 7 carries out corresponding analytic operation, then controls slipping mechanism to drive line-scan digital camera
6 and light source 5 move up and down suitable height of taking pictures, when examined object 2 is touched by camera
During hair switch 4, line-scan digital camera 6 is taken pictures to the bar code in examined object 2, and transport is flat
Multiple examined objects 2 can be placed on platform, so as to realize the company to the bar code in multiple objects
Continue scanning, after scanning is completed, the object transport that completion is detected to the end of transmission platform 1.
In sum, the continuous identifying device of bar code that the present invention is provided is using line-scan digital camera and transmission
Platform coordinates, and the height of examined object is detected using height finder structure, according to the height for detecting
The height of degree adjustment line-scan digital camera and light source, can be to different height to suitable picture-taking position
Bar code in examined object is identified, and can realize the bar code in multiple examined objects
Continuous identification, recognition speed is very fast, and high resolution, so as to solve existing bar code identification dress
Put that recognition speed is slow, height to examined object has limited problem.
