Rotating Corner Trimming for Photovoltaic Assembly Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In photovoltaic assembly production, residual curing adhesive at the four corners is difficult to remove with conventional trimmers, leading to instability and reduced reliability in the subsequent framing process and service life.
Innovation Solution
A secondary trimming device comprising first and second clamping drive apparatuses with blades, mounted on a fixing base, allows for precise removal of adhesive at corners by rotating and adjusting blades to cut and retract the adhesive effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional trimmer is used to remove curing adhesive, then the adhesive along the four sides can be removed, but the residual adhesive at the four corners cannot be removed
Solution Approach 1:
The device divides the adhesive removal task into two segments: a trimmer for removing adhesive along the four sides, and a secondary trimming device with rotating blades specifically for removing residual adhesive at the four corners. This segmentation allows each component to specialize in a specific removal task, achieving complete adhesive removal without requiring complex manual operations.
Solution Approach 2:
The secondary trimming device incorporates rotating blades that can dynamically adjust their position and orientation. The blades rotate to access different corner positions and can be driven by drive apparatuses to adapt to the curved geometry of corner adhesive, enabling effective removal where static trimmers fail.
2Reliability
If residual adhesive at corners is not removed, then the production process can proceed quickly, but the stability and reliability of the photovoltaic assembly is reduced
Solution Approach 1:
The secondary trimming device performs preliminary removal of corner adhesive before the framing process. By预先 removing the adhesive that would interfere with frame assembly, the device prevents future stability issues without requiring rework or additional corrective operations later in the production process.
Solution Approach 2:
The rotating blades act as an intermediary tool between the adhesive residue and the framing process. They provide a mechanical means to remove the problematic corner adhesive that neither the primary trimmer alone nor manual removal can efficiently address, ensuring clean corners for reliable frame assembly.
3Manufacturing precision
If manual removal of corner adhesive is attempted, then complete removal may be achieved, but the operation becomes more difficult and time-consuming
Solution Approach 1:
The rotating blades are driven by automated drive apparatuses that self-regulate the blade motion to match the corner geometry. The system performs the trimming action automatically without requiring manual intervention or complex operator skills, achieving complete corner adhesive removal while maintaining consistent processing speed and minimizing time loss.

AI summary
Provided is a secondary trimming device for a photovoltaic assembly. The secondary trimming device mainly includes first clamping drive apparatuses, second clamping drive apparatuses, and a fixing base. A blade is disposed on one side of one first clamping drive apparatus facing a photovoltaic assembly. The first clamping drive apparatus can drive the blade to get close to the photovoltaic assembly. One second clamping drive apparatus is connected to one end of the first clamping drive apparatus facing away from the photovoltaic assembly and can drive the first clamping drive apparatus to rotate. The first clamping drive apparatuses and the second clamping drive apparatuses are each disposed on the fixing base.
