SPC-EVO, a a very compact glass turntable system with interchangeable blister magazine for parts, is the latest patented generation of inspection equipment from Dimac dedicated to stamped fasteners and fine blanked components.
Optical measurements on the SPC-EVO are performed by high resolution >5 Mpixel GigE digital cameras with special telecentric lenses and coaxial light rings. The frame structure on wheels allows this unit to be placed in the most accessible location in the factory. It can be equipped with an optional rechargeable battery pack and therefore does not need a nearby electrical outlet to operate.
The operator’s task is to fill the interchangeable blister from 5 to 15 pieces (or more), insert the blister into the SPC-EVO and press the Cycle Start button to allow the machine to automatically load and check piece by piece in sequence. The innovative Dimac SPCx software can perform any type of measurement and characteristic by means of part profile analysis and on the surface of the pieces with direct light illumination.
The mobile station has been conceived as an innovative solution for SPC checks and data collection in the production environment, next to stamping/blanking machines. “Conventional manual measurements in manufacturing are slow and inaccurate, varying from person to person depending on how they are held, squeezed and interpreted,” explains Massimo Agrati, CEO at Dimac Srl. “The SPC-EVO concept has been subject to a validation process of eight months, directly at the factory of a Dimac customer, where the machine was installed in the production environment next to existing conventional manual SPC control stations. The comparison between the conventional method and the innovative SPC-EVO method has highlighted the main advantages of the Dimac solution.”
These advantages include the fact the SPC-EVO unit can support the SPC control process for a pool of 4 to 5 presses/machines nearby and the SPC checks can be performed by unskilled personnel – with the measurement accuracy improved to be within ±5μm. It is also no longer necessary to go to the metrological room to carry out complex measurements, which, when added together with the other time saving advantages, leads to approximately 30% to 50% of overall time being saved when compared to the conventional manual method.
The system also allows the operators to increase the number of controllable pieces for each SPC cycle, improving the consistency of the collected data and the quality control management.
“Other advantages include the fact that the SPC data collected is objective, free from human errors, available in ‘real time’ and accessible through the company network to be processed with the company ERP system,” concludes Massimo.
