Description
Technical field
The utility model belongs to the detection servicing unit field while adopting machine vision technique identification transfer belt coding, is specifically related to a kind of for gathering the shooting platform of transfer belt code-bar image.
Background technology
Transfer belt belongs to the continuous flexible material that can coil, conventionally uses reel to coil.Process caloric transfer printing technology transfer belt after treatment in having printed the coding that dispatches from the factory on imprinting product, residual lower and its corresponding consistent transparent transfer printing code-bar of encoding that dispatches from the factory on transfer belt self lower surface, transfer printing code-bar continuous in transfer belt is generated by heat and pressure continuously transfer printing by mechanical code-disc, because the high bit code of code-disc is without normal use, physical construction dirigibility is poor, therefore occasional produces and leaks code, repeat or the mistake such as smudgy, once this mistake produces, can on the product export coding of transfer belt code-bar and correspondence thereof, embody simultaneously simultaneously.At present, conventionally by manually checking one by one transfer belt code-bar with naked eyes, or, check one by one the code clerk that dispatches from the factory of product with naked eyes, but the efficiency of hand inspection is very low, easily causes visual fatigue, is also difficult to avoid artificial careless omission.
Word recognizer based on machine vision technique has been ripe industrial detection method, and it can carry out text location and cut apart according to the feature of character image, uses recognition principle word is classified and mate, to reach the object of identification.In theory, use industrial camera to take respectively a photos to each the transparent transfer printing code-bar in transfer belt, can complete identification to the transfer belt transfer printing code-bar on this photo by follow-up machine vision technique and extract and error-checking, complete rapidly the detection screening process to the error code of transfer belt and leakage code.
Transfer printing code-bar in transfer belt is from camera lens, to pass through in turn continuously, but its Negotiation speed becomes large and increases along with coiling the coil diameters of drive system, this just causes camera to capture its transfer printing code-bar under current by constant shutter frequency, but may photograph the linkage section of two adjacent code-bars, and then cause follow-up character-recognition errors.
On the other hand, theoretically, can use contactless position pick-up unit to detect the position of transfer printing code-bar, and accurately control accordingly the shutter triggered time of industrial camera, can make camera just can capture the transfer printing code-bar that current camera lens below is being passed through.But this requires pick-up unit can not stop the light path of camera, simultaneously can not be along the transmission direction of transfer belt, thereby stop and affect the even running of transfer belt, otherwise, be prepended to the modes of emplacement of the shooting visual field of camera according to pick-up unit, pick-up unit is received when current code-bar triggers, camera synchronization is received triggering and the scenery in current visual field is taken, but now, the code-bar of detection trigger device likely not yet enters among the visual field of camera, produce thus the photo of taking and in sequential, have mistake, finally cause Machine Vision Recognition Technology cannot the transfer printing code-bar in transfer belt correctly be taken pictures and be identified.
At present, on market, do not meet the transfer belt code-bar shooting platform of above-mentioned requirements completely, therefore, research and develop and a kind ofly have great importance for the shooting platform device that gathers transfer belt code-bar image.
