This invention relates to an intelligent screen printing device, a screen printing system, a control method, and a computer-readable storage medium, belonging to the field of thin-film battery manufacturing technology. The intelligent screen printing device is used for perovskite thin film screen printing and includes: a screen frame for supporting the screen; a tension sensing module disposed on the screen frame for real-time monitoring of the tension distribution in various areas of the screen; a temperature regulation module disposed on the screen frame for heating or cooling the screen; an electrostatic control module disposed above the intelligent screen printing device for generating an ion flow to eliminate static electricity accumulation during the printing process; and a control unit electrically connected to the tension sensing module, the temperature regulation module, and the electrostatic control module, respectively, for receiving monitoring signals and outputting control commands to achieve coordinated closed-loop regulation of tension, temperature, and electrostatics.

This invention discloses a method for monitoring the welding process quality of a volute housing seat ring, comprising deploying a digital dial indicator and configuring a wireless data acquisition module to establish a deformation data acquisition and transmission link; acquiring deformation data in parallel through multiple channels of the link and performing preprocessing; constructing a deformation monitoring model based on the preprocessed data, calculating the risk rate of a single measuring point, and then calculating the joint risk rate of multiple measuring points; and synchronizing the data to multiple terminals and performing interactive adaptation. This invention replaces manual reading with a high-precision digital dial indicator and wireless automatic acquisition, achieving objective and accurate acquisition and real-time early warning of deformation data; by constructing a deformation monitoring model and a quantitative model of the joint risk rate of multiple measuring points, it accurately characterizes the deformation correlation of multiple measuring points, realizing quantitative prediction of the overall structural deformation risk and proactive process guidance; and through multi-terminal data synchronization, it achieves traceability of the entire welding cycle data of the volute housing seat ring and multi-scenario adapted closed-loop monitoring, while being compatible with existing processes, thus improving the level of quality control.

This invention discloses an integrated preform weaving / needling / stitching mandrel and its matching sliding mechanism. The mandrel includes a rear stitching area, needle-punched reinforcing ribs, a middle needle-punched area, and a front stitching area. The matching sliding mechanism includes the mandrel, a rotating device, a lifting device, and a translation device. Compared to existing technologies, this invention integrates multiple processes such as weaving, needle-punching, and stitching, while simultaneously achieving stable and reliable forming of multi-process composite conical preforms.
