Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment proposes a shingled component lamination process, such as figure 1 shown, the steps include:

[0030] The semi-finished components 10 are controlled to perform pre-crosslinking and lamination in different chambers 20 in sequence, wherein the pre-crosslinking is to make the front adhesive film 12 and the rear adhesive film 13 in the semi-finished component 10 both hot-melt adhesive with the battery sheet 11 The purpose of lamination is to make the front adhesive film 12 and the rear adhesive film 13 both solidify and bond with the battery sheet 11 .

[0031] During the pre-crosslinking and lamination process, each chamber 20 includes a pre-pressing operation and a pressing operation, in order to control the silicone plate 23 in the upper chamber layer 21 to slowly descend in each chamber 20 The semi-finished component 10...

Abstract

The invention provides a lamination process for an imbricate assembly. The lamination process comprises the following steps: controlling a semi-finished product assembly to be pre-crosslinked and laminated in different chambers in sequence; in the pre-crosslinking and laminating processes, pre-pressurization and pressing operations are included in each cavity; in each chamber, the silica gel plate in the upper chamber layer is controlled to move downwards so as to abut against the semi-finished product assembly in the lower chamber layer; in the laminating process, when the upper chamber layer in the laminating chamber is inflated, the vacuum in the lower chamber layer is gradually released. According to the lamination process of the laminated tile assembly, the silica gel plate slowly falls in the lamination process, and local falling of the silica gel plate due to instant inflation and local stress of the assembly are reduced, so that the phenomenon of easy blistering in the lamination process is relieved, the lamination quality is improved, and the energy consumption of an assembly laminating machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar shingled component manufacturing, and in particular relates to a shingled component lamination process. Background technique [0002] The laminated packaging of solar cell modules is a crucial process link in the production process of solar cells, and it is also a key control point for the manufacture of solar cell modules. The quality of packaging determines the reliability, service life and performance of solar cell modules. And aesthetics are shaped here in the lamination. In the actual lamination process, it is easy to cause air bubbles to appear after lamination of some modules. These air bubbles will seriously affect the service life of solar modules, and at the same time cause moisture leakage and wet heat test failure. In the vacuum hot-pressing packaging process, whether EVA film or PVB film is used, there are often bubbles in components, and air bubbles have become the most prominent item...
