Abstract
The invention discloses a vacuum insulated panel inner pressure measurement device and a test method thereof. The vacuum insulated panel inner pressure measurement device comprises a shell, multiple groups of sucker systems with the same specifications, a single chip microcomputer, a liquid crystal display screen, a control panel, a barcode reader, a computer interface, a barcode printer interface and a data line, wherein each sucker system comprises an upper sucker device and a lower sucker device tightly matched; the control panel outputs a command to the single chip microcomputer; the single chip microcomputer automatically controls the sucker systems to carry out detection on the vacuum insulated panel according to the command, after operation is carried out on acquired data, and the data are outputted to the barcode printer, the computer and the liquid crystal display screen. The test result of the device is accurate and reliable, the test process is simple, and large-scale detection can be realized.
Description
technical field [0001] The invention relates to a device for measuring the internal pressure of a vacuum insulation panel and a testing method thereof, in particular to a device for measuring the internal pressure of a vacuum thermal insulation panel with a multi-group sucker system and a testing method thereof. Background technique [0002] Vacuum insulation panel (VIP) is a new type of ultra-high-efficiency insulation panel that has emerged in recent years. It is mainly composed of three parts: core material, barrier film and getter. VIP is made based on the principle of vacuum heat insulation. By filling the core material and maximizing the vacuum inside the board, it can block heat conduction, so that the board can achieve the purpose of heat preservation and energy saving. VIP has the characteristics of low thermal conductivity, small thickness, and environmental protection. It is suitable for products with high energy-saving requirements and has great technical and eco...
