CDS Length & Diameter Inspection System

Request a Quote


CDS Manufacturing designed and built this automatic length and diameter laser inspection system. This system measures eight different diameters and the overall length of pistons using laser measurement equipment.

The operator loads parts into the bulk hopper. The bulk hopper supplies parts to the vibratory bowl feeder. The number of parts in the vibratory bowl feeder is automatically maintained. Parts in the proper orientation are fed to a nest at the laser inspection station. When sensors detect a part present, tooling automatically transfers the part in front of the laser, and stops at each of the eight diameters to take a measurement. Finally, the overall length of the part is measured. Good and reject parts are gated accordingly and exit the system via their respective output chutes.

Part Description Piston
Industry Served Automotive
Machine Rate 30 parts per minute
Process Overview Parts are automatically fed via the vibratory bowl feeder to the laser inspection station. Laser inspection station inspects eight diameters and overall length. Parts that fail laser inspection are diverted to rejects output chute. Parts that pass laser inspection are gated as good parts and exit the system via the good parts output chute.
Flexibility No. Custom tooling. Dedicated system.
Optional Equipment Available Yes. Hopper elevator, good / rejects parts counter, sound enclosure, machine casters, parts packaging system.
