AI Technical Summary
Existing vacuum coating machines require repeated vacuum breaking and re-vacuuming when changing materials, which affects production efficiency. Furthermore, the coating layer is easily affected by vibration and contamination after coating, resulting in insufficient practicality.
A vacuum coating composite machine for photovoltaic backsheet optical films was designed, comprising coating, sealing, material changing and curing mechanisms. The material changing mechanism completes the replacement and flipping of the optical film under vacuum conditions, and the curing mechanism cures the coating in the vacuum sealing mechanism, thereby achieving continuous double-sided coating of the optical film.
It improves the practicality and automation level of the equipment, reduces auxiliary time and energy consumption, avoids the risk of coating contamination and cracking caused by vibration, and realizes efficient and automated coating of optical films.
