摘要： The invention relates to an arrangement for contactless determination of at least one dimension of a moving material web, in particular a material web of opaque material, with a background illumination, with optical detection means for detecting at least one current contrast image and with evaluation means, wherein the background illumination is arranged opposite the optical detection means, wherein the material web moves in a plane between the at least one optical detection means and the background illumination, and wherein the current contrast image has at least one piece of information about at least one light intensity laterally adjacent to the material web. Furthermore, the present invention concerns a corresponding process. For simplifying and improving the non-contact determination of the dimension, the present invention proposes to provide a shadowing element and to compare the current contrast image with a reference contrast image, wherein the current contrast image represents a shadowing of the background illumination by the material web and by the shadowing element.

摘要： Disclosed is a stone-block analysis device and method for the evaluation of stone blocks, in particular, concrete blocks to be arranged on a conveying device for conveying the stone blocks with a conveying surface for the stone blocks to be laid on, which extends into a longitudinal direction and into a transverse direction. The stone-block analysis device has at least one first scanner unit for scanning at least one physical characteristic of the stone blocks, an evaluation device for evaluating a signal output by the scanner unit, a control device, and a display device. The scanner unit is spaced away from the conveying surface in a vertical direction, perpendicular to the longitudinal direction and transverse direction. In addition to the first scanner unit, which is a point scanner, at least one second scanner unit is provided, which is a line scanner, wherein a height of at least one stone block can be detected by both scanner units.

摘要： The present invention relates to a fault detectable sheet body fixed distance conveying and punching assembly, which may include a rack, a conveying trough seat, a feeding trough, a processing rack and a punching device. On the rack is provided a feed motor and a feed screw. The movable feeding block is sleeved on the feed screw and the movable feeding seat is fixedly connected to the movable feeding seat. On the movable feeding seat is provided a feed lifting cylinder and on the feed lifting cylinder is provided a feed lifting block. On the feed lifting cylinder are equally provided feed blocks which may go through the feeding trough. On the processing rack is also provided a position detecting device which may include a detecting lifting cylinder provided on the processing rack. Under the detecting lifting cylinder is connected the detecting block. On the both sides of the detecting block is provided an acoustic wave range finder. The present invention includes a position detecting device, which may measure the position of the feeding block on the processing station by lifting the acoustic wave range finders on the position detecting device, and conduct integrity check to the fixed distance feeding part and maintain the entire assembly.

摘要： This application discloses an inspection method and an inspection machine for a display panel. The inspection method includes the steps of: taking a picture of a to-be-inspected display panel to obtain a to-be-inspected image of the to-be-inspected display panel; removing high-frequency information in the to-be-inspected image to obtain a high-frequency-removed image; calculating a difference between the to-be-inspected image and the high-frequency-removed image to obtain a difference image; making a determination regarding the difference image by comparing the difference image with a preset threshold, determining that the display panel fails the inspection if the difference image exceeds the preset threshold, and determining that the display panel passes the inspection if the difference image does not exceed the preset threshold.
