The RX-800-RB blast system from Guyson Corp. is designed to rapidly process fragile automotive electronic parts that require a precise degree of impact treatment on one side. It features an integrated, unmanned surface finishing work cell that combines robotic component handling with automated bead-blasting and optical inspection.
The system includes a six-axis Staubli TX-90XL machine-tending robot with a compact CS8C controller. Its robotic arm is fitted with a vacuum-style end effector to delicately and securely pick up, flip, re-orient and place the flat components before and after blasting in the multiple-gun bead-blast machine. Prior to blasting, each component goes through the optical inspection station, where it is gently placed in a dedicated fixture for imaging to detect cracked or broken parts and to confirm that the product is properly oriented with the correct side facing the camera. If an inverted part is found, the robotic machine tender will automatically remove and turn the product over for re-inspection, then proceed to load the passed component in the blast cabinet.
To ensure uninterrupted automatic operation, the blast system includes a number of electronic sensors that monitor critical conditions. For instance, blast media is automatically added to the machine when a low media level is detected in the hopper that feeds the blast guns. A separate low media level sensor in the adder supply hopper triggers a fault indication beacon and audible alarm to summon an attendant. Likewise, a full dust collector waste drum will result in a fault indication.
