Flexible assembly cold pressing process and device capable of automatically adjusting cooling rate

Abstract

The invention provides a flexible assembly cold pressing process capable of automatically adjusting the cooling rate. The process comprises the following steps of: 1, conveying a laminated assembly toa cold pressing platform, applying pressure to the assembly, and meanwhile, enabling cooling water in a cooling platform to flow all the time to continuously take away heat transferred to the coolingplatform by the assembly; 2, controlling the temperature difference between the cooling platform and the assembly; and 3, after the assembly is cooled to room temperature, taking out the assembly. According to the flexible assembly cold pressing device capable of automatically adjusting the cooling rate, a pipeline passes through the cooling platform, an upper cover plate is arranged on the cooling platform, the upper cover plate is connected to a rack in a liftable mode, cooling water passes through the pipeline, temperature sensors are installed on the cooling platform and the upper cover plate, and an electric flow adjusting valve is installed on the pipeline. According to the technical scheme, the assembly temperature and the cooling platform temperature are measured in real time, theflow of cooling water is adjusted in real time according to the temperature difference, and the defect of local upheaval caused by too high cooling speed is overcome.

Description

technical field [0001] The invention relates to the technical field of cold pressing, in particular to a cold pressing process and device for a flexible component that can automatically adjust the cooling rate. Background technique [0002] Cold pressing: Unlike double-glass modules, flexible modules are made of polymer plastics on the front and back sheets. After lamination, the temperature is as high as 160°C, and they immediately enter the cooling process. Double-glass modules can be cooled naturally without generating heat. Too much deformation, but flexible components are different. When the polymer material is cooled, it will shrink and deform violently. Therefore, for the cooling of flexible components, it is usually necessary to put a pressure on the component during cooling to prevent the component from cooling and deformation. Therefore, cold pressing is The component is cooled and pressure is applied at the same time to prevent the component from cooling and defor...

AI Technical Summary

Problems solved by technology

[0004] The existing cooling process is simple, the cooling water flow rate and cooling water temperature are constant values, and cannot be adjusted in real time. If the cooling water temperature is too high, the components will not be able to cool to room temperature. Components develop large deformation stresses that deform even under pressure, forming local bulges

Under the existing technology, the occurrence frequency of component local uplift is very high, which has become the main adverse factor of flexible components
