Problems solved by technology
[0003] At present, the methods of detecting the weld bead of pipe fittings can be roughly divided into radiation detection method and ultrasonic detection method. Among them, the radiation detection method is a non-contact detection method, although the radiation detection method can see the inside of the pipe fittings. defects, pores, cracks or slag, but the radiation is extremely harmful to the human body; and the ultrasonic detection method needs to place an ultrasonic vibrator in the pipe, and place the ultrasonic vibrator on each part of the pipe one by one. position detection, but the detection method must manually place the ultrasonic oscillator, so it is quite time-consuming. In this way, it is not conducive to the use in the automation industry that emphasizes efficiency
[0004] The above-mentioned existing pipe fitting weld bead detection methods are not in line with today's automation industry that emphasizes high efficiency and high economic benefits. Therefore, how to increase work efficiency and detect problems that need to be solved at present

The invention discloses a pipe fitting weld bead detection system, which is composed of a circular light source, an image capture device and an image processing device. The image processing device performs coordinate transformation on the image pixels captured from the pipe by the image capture device, so as to determine whether there is a pipe weld bead in the pipe, so as to further determine the position of the pipe weld bead in the pipe. In this way, it is avoided that when the pipe fitting is subsequently processed by laser, the laser damages the pipe fitting bead of the pipe fitting and causes the pipe fitting to be unable to be welded with other objects. Therefore, the pipe welding bead detection system disclosed in the present invention reduces the time of pipe welding bead detection to meet the needs of the automation industry.
Description
technical field [0001] The present invention relates to a pipe fitting weld bead detection system and method, in particular to a pipe fitting weld bead detection system and method for detecting whether there is a weld bead in a pipe fitting. Background technique [0002] In the process of laser processing of pipe fittings, the weld bead in the pipe fitting is often damaged due to laser irradiation to the pipe fitting bead in the pipe fitting. Resulting in inability to weld or incomplete welding. Therefore, detecting whether there is a pipe weld bead in the pipe fitting and detecting the position of the pipe weld bead in advance is a problem to be solved at present. [0003] At present, the methods of detecting the weld bead of pipe fittings can be roughly divided into radiation detection method and ultrasonic detection method. Among them, the radiation detection method is a non-contact detection method, although the radiation detection method can see the inside of the pipe ...
