Solar PV Module Assembly

In the final step, many PV cells are assembled into strings and packaged into a single unit, called a module. Machine vision ensures accurate cell spacing, construction, and part placement during module assembly. During stringing alignment and inspection, machine vision centers the PV cells, minimizing the need for mechanical contact, and examines the cells for defects while also verifying the continuity and correct assembly of each string. Multiple modules may be assembled into a solar panel.

Wafer-to-Package Traceability

Industrial image-based barcode readers handle even degraded, reflective, or low-contrast marks from die backsides, substrates, encapsulated packages, and PCBs for complete traceability. Barcode readers reliably track parts and identify wafers, PV cells, and modules throughout production and assembly.

Ingot Formation

Cognex machine vision products monitor ingot formation, providing precise dimensional measurements during the crystal pulling process. The In-Sight 8000’s small form factor and robust edge detection tool ensure the crystal seeding, shouldering, shoulder circuiting, and diameter equalizing stages are performed to exacting standards for proper ingot formation.
