Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar cell string production equipment is structurally complex due to the need for separate and alternating paths for back and front films, which complicates the production process.
Innovation Solution
The equipment includes a first and second conveying device with continuous conveyor belts, a carrying device, a transfer device, and a film-supplying device, allowing for the parallel and efficient conveyance of back and front films, and the reuse of a pressing tool, thereby simplifying the structure and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two conveyor lines are used to alternately transport back film and front film along different paths, then the solar cell string production can be achieved, but the production equipment becomes structurally complicated
Solution Approach 1:
The patent combines the transportation of back film and front film into a single conveyor line, where the conveyor belt alternately conveys both film types along the same path. This merging of previously separate transportation paths into one unified system reduces equipment complexity while maintaining production capability.
Solution Approach 2:
The single conveyor line is designed to perform multiple functions by alternately transporting both back film and front film. The conveyor belt serves as a universal transportation medium for different film types, eliminating the need for dedicated conveyor lines for each film type.
2Manufacturing precision
If separate paths are used for back film and front film transportation, then proper film placement is achieved, but the equipment structure becomes complicated
Solution Approach 1:
The conveyor belt is divided into distinct sections: a first conveying section for transporting back film and a second conveying section for transporting front film. This segmentation allows precise control and placement of each film type while maintaining a unified conveyor structure.
Solution Approach 2:
The patent transitions from separate spatial paths for different films to temporal separation on a single path. The conveyor belt alternates between transporting back film and front film in different time periods, achieving proper film placement without requiring physically separate transportation routes.

AI summary
A solar cell string production equipment includes first and second conveying devices, first and second carrying devices, and a transfer device. The first conveying device has a first continuous conveyor belt, the second conveying device has a second continuous conveyor belt, and the first and second continuous conveyor belts can turn and convey in the vertical direction. Back and front films are laid on the first conveying device. The first conveying device can transport the back film on the first continuous conveyor belt to the second continuous conveyor belt. The transfer device can transport the pressing tool from the terminal of the second continuous conveyor belt to the front film on the first continuous conveyor belt. The second carrying device can transport the pressing tool and front film stacked together to the second continuous conveyor belt. A solar cell string production method is further provided.
