Description

3D printing progress coding management and control device integrating wireless sensing technology Technical Field The invention relates to the technical field of progress coding control devices, in particular to a 3D printing progress coding control device integrating a wireless sensing technology. Background Along with the rapid development of additive manufacturing (3D printing) technology and the continuous expansion of application fields, higher requirements are put forward on accurate monitoring, intelligent management and quality traceability of a printing process. The progress monitoring of conventional 3D printing devices depends on a preset program flow or on-site observation of an operator, and lacks a dynamic and accurate sensing and feedback mechanism for real-time spatial positions of printheads, accumulated states of printing layers, and potential printing defects. The open loop control mode is difficult to realize timely early warning of printing abnormality, self-adaptive compensation of printing precision and full-flow digital traceability, and further improvement of printing quality, reliability and automation level is restricted; In the prior art, part of 3D printers attempt to integrate visual sensors or simple limit switches to monitor printing states, but the problems of single function, fixed installation positions, limited monitoring visual angles and the like often exist. For example, a fixed mounted camera is difficult to track a moving printhead or scan various areas of a large-size print, while a simple mechanical switch or encoder can only provide limited end-of-travel information, failing to acquire rich print process images and position data. In addition, the lack of an effective wireless data transmission module makes it difficult for monitoring data to be imported into an upper Manufacturing Execution System (MES) or an industrial Internet of things (IIoT) platform in real time, and remote monitoring and data-based progress coding management cannot be realized; Meanwhile, for a 3D printer (such as some stereolithography or fused deposition modeling devices) with a rotating or lifting structure, the printing module or the monitoring module needs to perform multiple degree of freedom adjustment in a wide range to optimize the observation or processing position. The existing adjusting mechanism is complex in structure and inconvenient to adjust, and after adjustment, a convenient and reliable locking mechanism is lacked, offset is easy to occur in printing vibration, and monitoring stability is affected. In addition, how to dynamically adjust the position of the monitoring module and synchronously realize the accurate compensation and calibration of the space coordinates thereof, and ensure the accurate correspondence between the acquired information and the printing coordinate system is also a difficulty in the prior art. Accordingly, improvements in the art are needed.
