Mollificio Torri: comprehensive quality control in micro spring manufacturing
Mollificio Torri takes a closer look at the vision system built into its new 6-axis electronic spring coiling machine. The equipment was recently installed to manufacture compression springs with wire diameters ranging from 0.10 to 0.80 mm.
The integrated vision system performs in-line dimensional inspection, continuously monitoring spring geometry and rejecting out-of-specs pieces.
Camera-based spring length inspection
A camera connected to dedicated hardware and software monitors the production process, measuring the length of each spring.
These measurements help detect dimensional irregularities caused, for example, by variations in spring diameter, coil count, or component deformation.
Unlike conventional sampling inspections, the system checks every single spring produced. This is particularly important when manufacturing micro springs from fine wire, where even the slightest dimensional variations can affect whether a spring meets the required specifications.
Automatic pneumatic rejection and defect alerts
When the vision system detects a spring outside the specified tolerances, a pneumatic rejection mechanism automatically diverts it into a separate container, preventing mix-ups with conforming parts.
The software also allows operators to set a defect threshold. When the number of detected defects exceeds this limit, the system automatically alerts the operator.
