A robotic dispensing system is said to improve adhesive dispensing and product assembly by eliminating problems such as the need to speed production, adhesive out of position, too much or not enough adhesive, excess waste, scrap or repairs and high production costs.
The Dual-Station XYZ Robotic dispensing system, from Sealant Equipment & Engineering, accurately and quickly dispense 1-part and 2-parts adhesives and sealants such as silicone, epoxy, urethane and acrylic for bonding, gasketing, potting, encapsulating, molding and sealing applications. The robot and dispensing system together stores all the dispensing programs created for every different part and is quickly recalled to start a production cycle.
The dispenser provides multiple capabilities for current and future production such as an ability to apply adhesive to two different parts having two different beads paths, or for parts needing two different adhesives applied, or to maximize the production rate for identical parts. Within each dispensing program, the adhesive or sealant can be applied at different flow rates to ensure proper material bead size or material flow to eliminate air entrapment.
The most common process has station-1 dispensing adhesive while a part is loaded in station-2. When station-1 completes dispensing, the robot in station-2 begins dispensing at the same time station-1 is being unloaded and reloaded to repeat the cycle. Loading and unloading can be performed manually or robotically. The best 1-part and 2-part dispensing systems use a positive-rod displacement controlled by servo-drive motors for fast and accurate bead profiles and flow rate dispensing. Sealant Equipment’s model Servo-Flo 401 and 801 metering systems are sized by total volume required and 2-part material mixing ratio.
