Projects Automotive Injector Clamping Inspection
Walsall Pressings is a well-established manufacturing company based in the West Midlands. The company specialises in technical metal presswork and is very active in the automotive industry, supplying tier one manufacturers with pressings, robotic welding and mechanical assemblies.
The company has a long-term contract to supply engine components to a global automotive manufacturer. One such component is a clamp retainer that is formed from a single piece of steel into a U shaped
Walsall Pressings has a commitment to produce well in excess of 500,0000 clamps in a 12-month period, such a high volume of components requires an automated visual inspection is critical in order to maintain quality both in the cosmetic appearance as well as for the verification of correct forming ensuring zero flaws.
The images are processed by Scorpion Vision Software on a compact PC located inside the inspection system. Image processing is carried out before inspection takes place, using software filters to normalise the light level across the image. The second stage of this image conditioning is the conversion of the images using a propriety filter within Scorpion Vision Software that ‘flattens’ the surface area to be inspected. The vision system then scans the structure and locates any marks or deviations in the surface of the metal.
The system operates in a semi-automatic manner in that it is ‘fed’ new clamps from a rotating bowl feeder singularly, with each inspection taking 8 seconds, the longest process being the time the clamp takes to travel along the conveyor before it arrives at the other end of the machine.
A pass will let the clamp continue on to the end of the conveyor and into a pallet ready for packaging. If a clamp fails inspection, a pneumatic device will open a trapdoor so that the clamp falls into a reject bin.
Walsall Pressings can be confident that the machine will inspect 100% of the parts and that any flaws in the surface of the metal will be detected.
