Embodiment Construction

[0034] figure 1 A vacuum lamination press with a press lower part 1 , a press upper part 2 as well as a heating plate 3 and a sealing frame 4 is shown in a schematic partial side view. A conveyor belt 5 and a separating film 6 run between the heating plate 3 and the sealing frame 4 . On the heating plate 3, between the conveyor belt 5 and the release film 6, a workpiece 7 is arranged for pre-lamination after the press shown is closed. The heating plate 3, the press upper part 2 and the sealing frame 4 form the boundary of the vacuum chamber 8 when the press is closed, which is divided by the insulating membrane 6 into a space delimited by the press upper part 2, the sealing frame 4 and the insulating membrane 6. The pressure half 9 and a product half 10 delimited by the heating plate 3 and the insulating film 6 . The product half 10 can be evacuated via a channel 11 which is only schematically shown, while the pressure half 9 can likewise be evacuated or charged with compres...

Abstract

The present invention relates to a method and device for laminating mainly plate-shaped workpieces with the use of pressure and heat, wherein the workpiece has at least a thermal activation adhesive layer. Firstly, at least one workpiece is supplied to a vacuum cavity of a vacuum laminating press, and the vacuum chamber is divided into a pressure half part and a product half part by an airtight flexible pressing member. In the product half part of the vacuum chamber, the workpiece is laminated with the use of heat, and the product half part is vacuumized, and the pressing member presses the workpiece directly or indirectly against one lower side of the vacuum chamber due to a pressure difference formed by vacuumizing and/or due to loading of the pressure half part of the vacuum chamber by an additional pressure. The vacuum laminating press is started to interrupt the laminating treatment, the workpiece is transferred to the press, and the press is applied by a temperature at or above an activation temperature and/or precipitation temperature of the adhesive layer. The invention is characterized in that a separate foil or foil together with the workpiece brought into the press or foil web guided by the vacuum chamber is utilized as the flexible pressing member.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for laminating substantially plate-shaped workpieces under the action of pressure and heat, and a corresponding apparatus according to the preamble of claim 10 . Therein the workpiece to be laminated has a multilayer structure and comprises at least one adhesive layer with an adhesive which can be activated by the action of heat and possibly hardens under the action of heat. A preferred field of application of the invention is laminated photovoltaic modules, in which the solar cell layers and their electrical contact elements are covered in a moisture-tight encapsulation and in a weather-resistant but light-transmissive covering. technical background [0002] It is within the scope of the present invention to employ vacuum lamination presses. The press contains a vacuum chamber which is hermetically closed when the press is closed and is divided into a product half and a pressure h...
