Problems solved by technology

[0005] The calibration cycle of the above calibration methods is about one month longer
And there is a lot of inventory for replacement
In addition, some laminators process data through programmable controllers, and display the vacuum value on the computer screen. When calibrating, the processor and thermocouple vacuum gauge need to be removed at the same time. However, there are no spare parts for this type of laminator, so Still can't calibrate

Description

technical field [0001] The invention relates to an on-line calibration device, in particular to an on-line calibration device and method for a vacuum system of a laminator used for solar module packaging, and belongs to the technical field of solar module packaging. Background technique [0002] The cross-sectional structure of ordinary solar panels, such as figure 1 As shown, it generally includes a tempered glass layer, an EVA layer, a battery sheet, an EVA layer, a TPT layer, and an aluminum alloy frame wrapped around the outer circumference of each layer from top to bottom. Among them, EVA is the abbreviation of polyethylene-polyvinyl acetate copolymer. It is a thermosetting and sticky adhesive film. used in the photovoltaic industry. While the EVA is heated and melted, the internal air needs to be exhausted to ensure that there are no air bubbles in the package, so the industry uses the vacuum feature of the laminator to achieve this purpose. [0003] Whether the vac...
