Powered by Cognex’s industry-leading software, Cognex vision-based products—systems, software, and industrial ID readers—are used for monitoring and inspecting everything from wet processing through metallization, firing, and color sorting.
Monitor solar cells to ensure correct upright orientation prior to the dopant application phase.
Inspect cells for chips and cracks to ensure any defective cells are rejected prior to processing.
Measure the position, width, and distance between the bus bars and check the continuity of finger lines.
Align cells and inspect the edge groove cuts along the wafer edges to isolate the emitters from the back sides of the cell.
Inspect and sort solar cells by slight color variances and grades the cells based on inconsistencies in the color.
Align cells for screen printing.
Transmit placement information for robot guidance applications used throughout the solar panel manufacturing process.
Inspect lines for contour breaks, continuity, and excess solder and ensure that traces are parallel and correctly registered.
