Equipment Application Introduction
The semi-automatic stencil inspection machine is a device that performs high-precision inspection on the cleaned stencils after printing. It is mainly used to control the quality of stencils after cleaning, optimize the process research and measurement of stencil openings, and at the same time automatically record and upload the results of the process of stencil use-cleaning-cleaning detection-use storage-scrap and achieves automated management of the information chain;
The equipment makes up for the shortcomings of low manual inspection efficiency, poor quality, inability to perform data management and traceability, and inability to improve the process. It provides a crucial reference for the improvement and quality control of the printing process.
Equipment Design principle:
Use image automatic measurement technology to collect parameters such as the opening size, opening position, and number of openings of the standard stencil, and then compare it with the cleaned stencil to determine whether it is qualified within the set error range.
