Solar Cell String Film Conveying With Reusable Pressing Tool
Solution Overview
Problem
The production of solar cell strings is complicated due to the need for alternately transporting back and front films on different conveyor lines, which increases equipment complexity and reduces production efficiency.
Innovation Solution
A solar cell string production equipment featuring a first and second conveying device with continuous conveyor belts, a carrying device, a transfer device, and a film-supplying device, where the conveyor belts are arranged in parallel and equipped with suction holes to hold films, allowing for the simultaneous handling and reuse of the pressing tool, and the continuous production of solar cell strings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two conveyor lines are used to alternately transport back and front films along different paths, then the solar cell string production can be achieved, but the equipment structure becomes complicated
Solution Approach 1:
The patent merges the transportation functions of back film and front film into a single conveyor line. The conveyor line sequentially transports both films along the same path, eliminating the need for two separate conveyor lines. This combining approach maintains the ability to produce solar cell strings while significantly simplifying the equipment structure.
Solution Approach 2:
The single conveyor line is designed to perform multiple functions: it transports both the back film and the front film, and also serves as a positioning reference for the pressing tool. This multi-functional design replaces the need for dedicated conveyor lines for each film type, reducing overall equipment complexity while maintaining production capability.
2Ease of manufacture
If two conveyor lines are used for transporting films alternately, then the production process can be completed, but the production efficiency is reduced
Solution Approach 1:
The single conveyor line operates continuously to transport both back and front films without interruption. The films are moved in sequence along the same path, allowing for continuous production operations. This eliminates the inefficiencies associated with switching between two separate conveyor lines and maintains steady production flow.
Solution Approach 2:
The conveyor line is designed to transport the back film first, followed by the front film in a predetermined sequence. This preliminary arrangement of film transportation ensures that all components are in position before the pressing operation begins, streamlining the production process and improving overall efficiency.
3Ease of manufacture
If the pressing tool is transported alternately with films on different conveyor lines, then the production process can be followed, but the equipment structure becomes more complex
Solution Approach 1:
The pressing tool transportation is merged with the film transportation on the same conveyor line. The pressing tool is positioned on the conveyor line and moves together with the films, eliminating the need for separate pressing tool transport mechanisms. This integration simplifies the equipment structure while ensuring proper positioning for the lamination process.
