Description
Technical field
The utility model relates to a kind of punched-card, particularly a kind of quality detector of punched-card.
Background technology
Punched-card is widely used on the traditional textile jacquard.Automatically the card that goes out of card nipper punching out the phenomenon of makeing mistakes in porous or few hole occurs through regular meeting, uses to contain the woven product of the punched-card of makeing mistakes and be waste product.Present quality testing to punched-card, usually adopt Photoelectric Detection, utilize sensor devices, porose or atresia on the card is detected, but the equipment that is used for Photoelectric Detection must all will be equipped with a cover photoelectricity testing part on each position, hole, and the relative positional accuracy of photoelectricity testing part and card is had relatively high expectations, specification to card also has specific requirement, can't adapt to the variation of card specification.
Summary of the invention
The purpose of this utility model is that video and image recognition technology are applied in the quality testing of traditional punched-card, and a kind of quality detector of punched-card simple in structure and detection method are provided, and can be apace the punched-card of any specification be carried out quality testing.
A kind of quality detector of punched-card, comprise support 1, arrange the cylinder 2 that punched-card is used, this cylinder 2 is horizontally disposed, be installed on the support 1, a plurality of register pin 2a that match with the punched-card pilot hole are housed on it, it is characterized in that: be provided with camera 3 and gear train 4, camera 3 is installed on the cross bar 5, and the two ends of cross bar 5 are fixed on the support 1 by column 6; Gear train 4 is made of by belt pulley 4a, a thumb wheel 4b, the 4c that pulls pin, sheave 4d that belt drives a motor, sheave 4d is provided with 4 grooves that match with the 4c that pulls pin, belt pulley 4a and thumb wheel 4b coaxial arrangement, this axle is installed on the support 1, sheave 4d and cylinder 2 coaxial arrangement; The groove of register pin 2a and sheave 4d meshes successively; The card information that camera 3 collects sends robot calculator to and handles, and provides testing result; Register pin 2a adjustable positions on the cylinder 2.
A kind of step of punched-card quality testing is as follows:
A) write the control data collection that moves in the computing machine and the detection control program of processing procedure;
B) the view picture punched-card that will be arranged in order and sew up places on the cylinder of detector, detect control program and carry out the initial calibration location, confirm that all apertures are all on video image, detect control program and read in standard punched-card data, start the card measuring ability, start the gear train of card detector, begin automatic testing process;
C) detect control program by windows API, the control camera carries out video data acquiring, and current data that collect and the preceding data that once collect compare, and by the difference degree of data message, judge that current card is in motion/stationary state; After confirming that current card is static, the effective video view data is preserved; This is preserved the vedio data that gets off carry out pre-service, i.e. removal of images interfere information, and, identify the porose or atresia on the card field by recognizer, generate current video card data in view of the above;
D) current video card data and standard card data are compared, error message is added up and indicated, after this detect control program and enter waiting status; When switching to next card, proceed to detect, till all punched-cards detections finish.
With prior art relatively, the utlity model has following advantage: 1) because the alignment pin position on the cylinder is adjustable, detector is suitable for the quality of the punched-card of multiple different size is detected; 2) with camera collection card information, the video data of high precision and high definition can be provided, and adopt the Flame Image Process and the recognition technology in the present age, can effectively eliminate the interference of extraneous factor, improve the accuracy of identification; 3) gear train of detector is simple, and is not high to its accuracy requirement, and the production cost of detector is low.The testing result that card nipper provides according to this detector goes out wrong card correction to what porous or few hole occur, eliminates traditional Photoelectric Detection equipment.

Embodiment
Embodiment 1:
A kind of quality detector of punched-card, its structure as depicted in figs. 1 and 2, comprise support 1, arrange the cylinder 2 that punched-card is used, this cylinder 2 is horizontally disposed, is installed on the support 1, a plurality of register pin 2a that match with the punched-card pilot hole are housed on it, it is characterized in that: be provided with camera 3 and gear train 4, camera 3 is installed on the cross bar 5, and the two ends of cross bar 5 are fixed on the support 1 by column 6; Gear train 4 is made of by belt pulley 4a, a thumb wheel 4b, the 4c that pulls pin, sheave 4d that belt drives a motor, sheave 4d is provided with 4 grooves that match with the 4c that pulls pin, belt pulley 4a and thumb wheel 4b coaxial arrangement, this axle is installed on the support 1, sheave 4d and cylinder 2 coaxial arrangement, the groove of register pin 2a and sheave 4d meshes successively; The card information that camera 3 collects sends robot calculator to and handles, and provides testing result; Register pin 2a adjustable positions on the cylinder 2.
Fig. 3 is the computer-controlled program process flow diagram of this detector, punched-card to be measured is placed on the cylinder of detector, adjusts alignment pin position, and card is positioned.Detection is undertaken by following program 4: detector is calibrated N1, read standard card data N2, start card trace routine N3, start gear train, the beginning card detects, reading video data N4 judges whether static N5 of video image, not static continuation reading video data N4, if it is static, then enter video image and handle and discern N6, analyze card data N7, compare N8 with standard card data, judge whether card porous or few hole N9 occur, porous is arranged, and there is few hole at this place, position, hole with the red N10 that indicates, place, corresponding position, hole indicates N11 with green, judge to detect whether all finish N12 afterwards, then show statistical information N13 if finished, this this card detects and finishes N14.The N9 judged result does not exist porous or few hole, and is promptly consistent with the standard card, then directly enters N12; All do not finish if N12 judges to detect, then switch to next card N15, turn back to N4 simultaneously.
