Detection method and detection system of laser cutting tooling and pasting state

Abstract

The invention provides a laser cutting tool, and a workpiece and laser cutting tool attachment status detection method and system. The method comprises the steps that a workpiece to be cut is mounted on the laser cutting tool; the laser cutting tool acquires first displacement signals of the workpiece and a base molded surface at a plurality of displacement sensors through the plurality of displacement sensors; a signal acquiring device conducts amplification processing, conditioning processing and isolation processing on the first displacement signals and transmits the first displacement signals to an information processing terminal; and the information processing terminal outputs a first detection result according to a preset first threshold value and the first displacement signals. Through the laser cutting tool and the attachment status detection method and system, track errors caused by attachment errors of parts are avoided; the cutting precision of large three-dimensional parts is improved; and part out-of-tolerance and scrapping caused by poor attachment are avoided.

Description

technical field [0001] The present invention relates to the detection technology field, in particular to the detection technology in the laser cutting process, specifically a laser cutting tool, a detection method and a detection system for the sticking state of the workpiece and the laser cutting tool. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, laser cutting uses a focused high-power-density laser beam to irradiate the workpiece, so that the material at the irradiated place is melted, gasified, ablated or reached the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam, thereby A thermal cutting method that realizes cutting the workpiece. Laser cutting technology has been widely used in...

Problems solved by technology

Due to the visual inspection of the large-scale three-dimensional workpiece and laser cutting tooling, the human eye can not check the middle part due to the impact of accessibility, making it an important factor affecting the dimensional accuracy of the workpiece.
