[0002] In the power electronics industry, such as semiconductors, photovoltaics, or thin films, the copper indium gallium selenide (CIGS) module is laminated using tempered glass, PVB film, CIGS chips, PVB film, and tempered glass. Because the PVB film will oxidize when in contact with air for a long time, resulting in a large number of bubbles during the lamination process, it needs to be placed in a vacuum environment within 24 hours after the lamination is completed and heated to melt the PVB film and adhere the tempered glass and chips.
[0003] Due to varying market demands, the size and thickness of CIGS modules are constantly changing. To adapt to the market and save equipment costs, some products, due to size and thickness issues, cannot be processed in-house. These products must be packaged and shipped to a suitable manufacturer for processing. Therefore, it is necessary to provide a vacuum packaging device for glass laminates. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a vacuum packaging device for glass laminates, which can ensure that the glass laminates are stably stacked and prevent the PVB film from being oxidized.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] Figure 1 This is a schematic structural diagram of a vacuum packaging device for glass lamination according to the present invention.
[0016] See Figure 1 The vacuum packaging device for glass laminated provided by the utility model includes a vacuum pump 1 and a vacuum membrane 7 for accommodating the glass laminated layer. The vacuum pump 1 is equipped with a regulating valve 2, and the vacuum membrane 7 is equipped with a suction nozzle 6; the suction nozzle 6 is connected to the regulating valve 2 through a vacuum pipeline 3, and a one-way valve 4 is connected between the suction nozzle 6 and the vacuum pipeline 3.
[0017] The vacuum packaging device provided by the present invention comprises a vacuum pump 1 comprising a combined Roots pump and a mechanical pump, capable of rapidly controlling the pressure within the vacuum membrane 7 to maintain within 100 Pa. The regulating valve 2 can be used to adjust the pumping rate, and the one-way valve 4 prevents air from flowing back into the vacuum membrane 7, ensuring a high vacuum state within the membrane. A pressure gauge 6 is provided between the vacuum membrane 7 and the one-way valve 4 to display the pressure within the vacuum membrane 7.
[0018] Please continue to see Figure 2The vacuum packaging device provided by the present invention comprises a first tempered glass 8, a first PVB film 9, a CIGS chip 10, a second PVB film 11 and a second tempered glass 12 stacked in sequence; the first tempered glass 8, the first PVB film 9, the CIGS chip 10, the second PVB film 11 and the second tempered glass 12 are aligned with each other.
[0019] The vacuum packaging device provided by the utility model Figure 2 The glass layers in the Figure 1 Inside the medium vacuum membrane 7, turn on the vacuum pump 1 and adjust the size of the regulating valve 2 to control the pumping rate. When the pressure on the pressure gauge 5 reaches within 100 Pa, close the regulating valve 2, and then disconnect the vacuum pipe 3 from the one-way valve 4. This will maintain the pressure inside the vacuum membrane 7 within 100 Pa. The high vacuum pressure can align the layers of the glass laminate with each other and keep them in position, so that the CIGS laminated assembly will not shift during transportation, and the position error will be within 1 mm. This will isolate the first PVB film 9 and the second PVB film 11 from contact with the air and prevent oxidation, thereby avoiding waste of manpower and time and reducing transportation costs.
