Alignment method and system for manufacturing film photovoltaic assembly

Abstract

The invention discloses an alignment method and system for manufacturing a film photovoltaic assembly. The film photovoltaic assembly is provided with a transparent conductive oxide (TCO) glass plate, wherein the TCO glass plate is arranged on a workbench. The alignment method comprises the following steps: obtaining the preliminary position information of the TCO glass plate; according to the preliminary position information, carrying out coarse alignment to the TCO glass plate; obtaining the corner position information of the TCO glass plate by capturing the corner image of the TCO glass plate; and precisely aligning the TCO glass plate according to the corner position information. The invention simultaneously discloses an alignment system for manufacturing the film photovoltaic assembly. The alignment method and system for manufacturing the film photovoltaic assembly have low realization cost and are easy to realize, convenient and effective, the alignment problem in the manufacture process of the film photovoltaic assembly is eliminated, and therefore the production process is kept stable.

Description

technical field [0001] The invention relates to the field of manufacturing thin film photovoltaic modules, in particular to an alignment method and system for manufacturing thin film photovoltaic modules. Background technique [0002] In recent years, solar photovoltaic technology has made great breakthroughs, especially in building integrated solar photovoltaic. Building integrated solar photovoltaic is to install solar photovoltaic power generation components on the exterior wall or roof of the building, or directly serve as the curtain wall of the building to provide electricity. The advantage of BIPV is that photovoltaic modules are integrated with buildings, which can generate electricity locally, without the need to build another power station, and without long-distance transmission, which reduces power loss. At present, BIPV has made great progress in building energy conservation, and has great development prospects in both urban and rural areas. [0003] According ...

AI Technical Summary

Problems solved by technology

Since there is no alignment mark for the P1 process on the TCO glass 11, precise alignment cannot be performed during the P1 process

Since the alignment of subsequent laser scribing processes such as P2, P3, and P4 all need to use the cross mark generated by the P1 process, alignment problems arise on the production line including these subsequent laser scribing processes.

Misalignment can lead to machine failure and large product fragments

It is very important to control the position accuracy of the lines marked in the P1 process, and in traditional production, only the position sensor in the laser marking process is used to determine the position of the lines marked in the P1 process, which will cause potential displacement risks , and the production process will become unstable
