Design And Experimental Study Of Panel Type Solar Cell Module Laminator

The photovoltaic industry has a strong development potential in China,and the demand for photovoltaic products is also increasing.Among them,solar cell modules are important components in photovoltaic products,and their lamination equipment has a very important impact on the development of the photovoltaic industry.The solar cell module laminator mainly laminates the stacked battery modules on the solar cell module production line to bond the battery modules into a whole.The advantage of the plate type solar laminator is that the flatness of the laminated battery module is better than that of the vacuum type laminator,which is more suitable for the lamination of photovoltaic curtain walls and photovoltaic tiles.This article takes the panel solar cell module laminator as the research object,and uses the 3D modeling software Solidworks2018 and the finite element analysis software ANSYS Workbench to design and simulate the panel solar laminator.The main contents are as follows:Firstly,Solidworks 2018 is used to perform solid modeling on the lamination part of the laminator,and finite element analysis is performed for the main structures such as the laminate and the heating plate.The static analysis of the laminate is performed using ANSYS Workbench.From the simulation results,it can be seen During the lamination process of the laminate,the deformation of the bottom surface of the laminate is less than 3.7012×10^-9and the deformation is uniform,which indicates that the force applied by the battery components is balanced during the application of the electric cylinder.The preset heating temperature of the heating plate is 150℃From the simulation results,it can be seen that the temperature in the lamination interval on the surface of the heating plate is 149.11℃-149.65℃,which fully meets the lamination requirements.The maximum edge deformation is 7.1256×10^-7mm.It’s deformation is small,And it does not affect the lamination effect.Secondly,the electric cylinder servo system of the laminator adopts a master-slave control scheme.Combined with the accuracy of the electric cylinder,the closed-loop control accuracy reaches 5um,which can realize the synchronous control of the four electric cylinders.By drawing the electric control system of the laminator,It can realize the signal transmission between the control panel and the laminator;through PLC program programming,the laminator equipment can be automatically controlled to control the effective operation of the laminator.Thirdly,the orthogonal test method is used to study the effects of lamination temperature,lamination time,and vacuum on the quality of the lamination.The test plan is set by theL₄（2³）orthogonal table,and the battery module is laminated using the simulation prototype.The relevant analysis of the pressed battery module was carried out,and the following conclusions were reached:when the lamination temperature was 148℃to 150℃,the lamination time was 15-18 minutes,and when the vacuum degree reached 60-80Pa,the laminator was the best compression quality.
