Automatic corrugated pipe detection equipment and detection method

Abstract

The invention discloses automatic corrugated pipe detection equipment, which is used for detecting external defects of corrugated pipes produced by a corrugated pipe production line. The automatic corrugated pipe detection equipment is characterized in that the equipment comprises a pipe inlet hole, a conveying device (1), an image acquisition device (2), a judgment device (3) and a pipe outlet hole; the corrugated pipe coming from the corrugated pipe production line enters the conveying device (1) from the pipe inlet hole of the equipment and is output from the pipe outlet hole after the corrugated pipe is detected; guide rails (11) which are used for bearing the corrugated pipe and elastic pressing wheels (12) used for clamping the corrugated pipe to enable the corrugated pipe to drive are arranged in the conveying device (1); the image acquisition device (2) is provided with two or more than two image sensors (21), and the image sensors (21) are installed in the conveying device (1) and are arranged on the two sides of the guide rails on which the corrugated pipe is conveyed; and the judgment device (3) is connected with the image acquisition device (2), and is used for processing according to corrugated pipe images acquired by the image acquisition device (2) to obtain the actual parameters of the detected corrugated pipe and comparing the actual parameters with parameters in a digital template of a standard corrugated pipe sample to judge whether the corrugated pipe has defects or not.

Description

technical field [0001] The invention relates to the fields of production and quality control of corrugated pipes, and in particular proposes a device and method that can be connected to a corrugated pipe production line to detect defects in the shape of the corrugated pipes. Background technique [0002] At present, the corrugated pipes produced from the corrugated pipe production line are generally inspected manually and judged by human eyes to see whether there are deformation defects. This method not only wastes human resources, but also often causes missed inspections and cannot accurately identify defects. [0003] Because bellows often have wrinkled shells, especially plastic bellows, if traditional industrial video inspection is used, the bellows are easily deformed during the inspection process. For example, the Chinese patent "Defect detection device and method for pipes" (ZL200680036704) is not applicable to bellows; in addition, the Chinese patent "Deformation de...

Problems solved by technology

It cannot be connected with the corrugated pipe production line, and it also uses the original storage machine for detection, so it cannot be widely used in the automatic detection of various corrugated pipes
