AI Technical Summary

Technical Problem

In existing solar cell lamination processes, the film strips are prone to positional shifts during transfer, resulting in low lamination accuracy. Furthermore, the lack of a positioning and calibration mechanism for the solar cells affects the alignment accuracy between the solar cells and the film strips.

Method used

The cell bonding inter-film unit, which includes a pre-conveying unit, a calibration unit, a film strip supply unit, a heating and conveying unit, a first conveying mechanism, and a rear-conveying unit, simplifies the process flow, avoids film strip position deviation, and improves bonding accuracy by using multi-level positioning calibration and direct conveying of film strips to the cells on the heating and conveying unit.

Benefits of technology

It simplifies the film strip transfer process, improves film application accuracy and work efficiency, ensures accurate positioning of solar cells and film strips, and enhances the quality of solar cell string welding.

Abstract

This application relates to the field of solar cell manufacturing technology, and discloses a solar cell lamination unit and its working method. The lamination unit includes a pre-conveying unit, a calibration unit, a film strip supply unit, a heating and conveying unit, a first transport mechanism, a rear conveying unit, and a second transport mechanism. The calibration unit is located on one side of the pre-conveying unit and is used to position and calibrate the solar cells. The film strip supply unit includes a film supply unit and a film cutting unit, used to provide pre-cut film strips. The first transport mechanism is used to transport the calibrated solar cells from the pre-conveying unit to the heating and conveying unit, and to transport the film strips onto the solar cells on the heating and conveying unit. The second transport mechanism is used to transport the laminated solar cells from the heating and conveying unit to the rear conveying unit. By integrating calibration, film supply, transport, and heating and conveying functions, this application enables direct pickup and lamination of film strips, simplifying the process and improving lamination accuracy and efficiency.
