AI Technical Summary
In traditional thermoforming film lamination processes, pressure fluctuations caused by material deformation or differences in cavity sealing can lead to film displacement, wrinkles, or localized tensile cracking. The lack of a real-time feedback mechanism makes it difficult to adapt to the needs of complex curved surface molding.
By monitoring the membrane material displacement deviation in real time and dynamically adjusting the opening of the electronic valve to regulate the vacuuming rate of the cavity, the membrane material is accurately positioned and stress balanced with the preset reference surface. A laser detector is used to detect the membrane material position in real time, and the vacuum level is adjusted by a PLC controller to compensate for the displacement deviation.
It achieves precise positioning and stress balance of the membrane material before application, solving the problems of membrane material misalignment, wrinkles, or localized tensile cracking, improving the application accuracy to within ±0.1mm, and reducing the scrap rate by more than 30%.
