The JL-24-IN-3D 3D size detection device for plates is a laser inline detection device that can quickly scan and reconstruct the point cloud of the plate's three-dimensional size, facilitating real-time size detection and verification of products by the user. The device's detection range includes the planar size of the plate and the depth gap of the flow channels. The equipment can be integrated into an automated detection production line for batch loading and unloading, intelligent detection, and intelligent sorting based on the results. It also generates detection logs, analyzes changes in production yield, and provides guidance for process improvements. Product Features: The device uses a 2D and 3D fusion detection technology, combining the advantages of laser measurement and optical imaging to achieve micrometer-level precision detection; the device uses self-developed high-precision 3D image stitching algorithm and efficient closed-loop motion control algorithm to simultaneously meet the user's dual needs for high-precision and high-speed detection; The software has a high degree of openness and can customize functional modules according to user working conditions, and can communicate and interact with the user's existing MES system; the device has diverse forms, and can be used as a standalone unit for laboratory detection or quickly retrofitted into a detection line.
