Embodiment 1

[0015] A kind of perforated corrugated plate quality detector, its structure is shown in Fig. 1 and Fig. 2, comprises support 1, arranges the cylinder 2 that perforated corrugated plate is used, and this cylinder 2 is arranged horizontally, is installed on the support 1, is equipped with A plurality of positioning pins 2a matched with the positioning holes of the perforated cardboard are characterized in that: a camera 3 and a transmission mechanism 4 are provided, the camera 3 is installed on the cross bar 5, and the two ends of the cross bar 5 are fixed on the bracket through the column 6 1; the transmission mechanism 4 is composed of a pulley 4a driven by a motor through a belt, a thumb wheel 4b, a pull pin 4c, and a sheave 4d. The sheave 4d is provided with 4 grooves that match the pull pin 4c, and the pulley 4a and the dial 4b are coaxially arranged, the shaft is installed on the bracket 1, the sheave 4d and the drum 2 are coaxially arranged, the positioning pin 2a is enga...

Embodiment 2

[0019] If it is replaced with another punched cardboard with different specifications for quality inspection, it is only necessary to adjust the position of the positioning pin on the drum. All the other are identical with embodiment 1.

Abstract

A mass detector and detecting method of punched-plate is disclosed that characterized in that the perforated or imperforate information of punched-plate is collected by pick-up head, transferred to computer to be processed, and compared with standard card, detecting result is given out. Compared with current technology, the advantages of the invention are following: 1) a detector fits for the mass detection of punched-plate with different formats because of the adjusting of alignment pin position in roller; 2) collecting the information of punched-plate with pick-up head can provide high-accuracy and high-definition video data, the adoption of current image processing and identification technology can effectively eliminate the interference of extrinsic factor and improve the accuracy of identification; 3) the actuator of the detector is simple, the required precision is not high, the cost of manufacture of the detector is low.

Description

technical field [0001] The invention relates to a punched cardboard, in particular to a punched cardboard quality detector and a detection method thereof. Background technique [0002] Perforated pattern boards are widely used in traditional textile jacquard machines. The pattern punched by the automatic pattern punching machine often has many holes or few holes, and the products woven with the punched pattern containing errors are waste products. At present, photoelectric detection is usually used for quality inspection of punched card boards. Photosensitive devices are used to detect whether there are holes or no holes in the cardboard. However, the equipment used for photoelectric detection must be equipped with a There is a set of photoelectric detection devices, and the relative position accuracy requirements of the photoelectric detection device and the cardboard are relatively high, and there are also specific requirements for the specifications of the cardboard, whi...
