A new concept in robotic vision cells has been developed by longtime machine tool builder, Belden Machine. This unique concept acts as an inline inspection machine, capable of examining up to 150 component features in only five seconds. Unlike inline, stationary cameras, however, the Belden vision cell is equipped with an articulating robot arm that pulls product off a conveyor feed line, presents it to a single or multiple camera viewing station, then returns the part to the assembly process or rejects it into containers segregated by error factors.

During the inspection process, various product features are inspected, including overall dimension, component presence, relative position, even pressure and markings.

A 5- or 6-axis robot features an automatic tool changer for various parts, each programmed into the onboard PLC/HMI console.

The Belden vision cell performs automatic validation cycles, based on the preset values programmed.

Program cycles can be reviewed on the easy-to-read touch screen in real time.

The cell has onboard Ethernet connectivity for uploading data to a host process controller.

Options for parts feeding include an inline conveyor, vibratory bowl or centrifugal feed mechanism.

(Unit shown in photo has inline conveyor.) Also available from Belden are secondary assembly stations for post-inspection procedures, as well as part marking mechanisms for ink jet, laser or impact marking.

Secondary gauging options include color sensors, LVDT height inspection, pressure testing devices and marking scanners.

The Belden cell features a rugged fabricated steel machine frame and camera mounts, an extruded aluminum safety enclosure with locking guard door and robotic safety circuit.

The cell can accommodate scalable payload capacities of 0-2.5kg, 2.5-5.0kg or 5.0-10.0kg.

The unit shown in the accompanying photos is currently used by a Tier One automotive supplier to check clutch ring assemblies for dimensionality, sprag placement and relative ring position.

A laser checks the overall height of the ring, while the inspection camera is 'shown' all sides of the assembly by the articulating robot arm.

132 features of the assembly are checked in approximately five seconds.

Belden also offer the robotic vision cell for appliance, pharmaceutical, consumer electronic devices and various packaged goods applications, where multiple features in multiple locations require inspection in minimal cycle times.

Interested parties should contact Belden with the requirements of their applications.
