Title:
VACUUM INSULATION PANEL MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/217232
Kind Code:
A1
Abstract:
A miniaturizable vacuum insulation panel manufacturing device is provided. In this vacuum insulation panel manufacturing device (2), a vacuum insulation panel (11) is manufactured by surrounding a thermally insulating core member (10) with packaging members (20, 30) in which an exhaust port (32) is provided, creating a vacuum by evacuating air inside of the packaging members (20, 30) from the exhaust port (32), and sealing the exhaust port (32) with a sealing member (60), wherein this vacuum insulation panel manufacturing device is provided with: a chamber (210) with an opened bottom; a chamber exhaust hole (215) provided in the chamber (210); a quartz glass window unit (214) provided in the top of the chamber (210); a holding unit (251) which can hold the sealing member (60); a lifting mechanism (250) which raises/lowers the holding unit (251); a frame member (301) which holds and raises/lowers the chamber (210); and a laser welding unit (300) provided outside of the chamber (210).
