Glue Dispensing

Glue dispensing  is an  application that requires high precision and consistency. SCARA robots or compact 6 axis robots are ideally suited for glue dispensing applications. 

Combined with vision systems  for bead dimension checking, robots can be used to dispense glue on a variety of components. Component feeding systems and operator loading stations can be integrated safely into the solution. Dual loading station ensure that the robot is fully utilized for dispensing thus improving productivity.  

Lean Cells can be developed for glue dispensing applications based on the customer requirements 

We integrate the following elements for perfect glue dispensing

  • Infeed and outfeed system for part handling
  • Operator stations for part feeding and removal
  • Servo dispensing pumps for precise dipensing
  • Vision or laser based monitoring for volume and dimensional accuracy

BENEFITS OF ROBOTIC GLUE DISPENSING

Robotic unscramblers have several advantages when compared to conventional unscramblers
  • High precision and consistency
  • Material savings due to reduced wastage
  • Operators are isolated from sticky substances and harmful chemicals
  • Vision based monitoring for closed loop operation
  • Flexibility in terms of new variant addition

FREQUENTLY ASKED QUESTIONS

Synapse uses SCARA robots or compact 6-axis robots for glue dispensing applications. SCARA robots are ideally suited for planar dispensing tasks requiring fast horizontal motion. Compact 6-axis robots are used where the dispensing path requires movement along more complex trajectories. The robot type is selected based on the component geometry and the dispensing path required.

A typical Synapse glue dispensing cell integrates four key elements: an infeed and outfeed system for part handling, operator loading and unloading stations, servo dispensing pumps for precise application, and a vision or laser-based monitoring system for verifying bead volume and dimensional accuracy. These elements are combined into a complete cell tailored to the customer’s component and production requirements.

The cell is designed with dual loading stations — while the robot is dispensing on one part, the operator loads or unloads at the other station. This ensures the robot is continuously dispensing rather than waiting for parts to be loaded. The result is higher robot utilisation and improved overall productivity from the cell.

Vision or laser-based monitoring is integrated for closed-loop quality control. After dispensing, the system checks the bead for dimensional accuracy and volume — confirming that the correct amount of adhesive was applied along the correct path. This closed-loop feedback enables the system to detect dispensing faults immediately rather than relying on downstream inspection.

The main benefits are high precision and consistency in bead placement, material savings from reduced adhesive wastage, improved operator safety by isolating workers from sticky substances and potentially harmful chemicals, and flexibility to accommodate new product variants without significant reconfiguration. Vision-based monitoring also enables continuous quality verification that is not practical with manual dispensing.

A Lean Cell is a compact, purpose-built automation cell designed around the specific dispensing requirements of a customer’s components. Rather than a large, fixed automation line, a Lean Cell is sized and configured for the actual production volume and part variety, minimising floor space use while maximising the efficiency of the dispensing process. Synapse develops Lean Cells based on the customer’s specific requirements.
Synapse’s glue dispensing solutions serve four primary industries: Electronics — including circuit board sealing, smartphone and tablet assembly, and potting/gasketing; Medical Devices — for adhesive bonding in products such as syringes and catheters; Automotive — including windshield bonding, gasket dispensing, headlamp sealing, and EV battery assembly; and LED Lighting and Solar — covering solar panel junction box potting and LED lens attachment and fixture sealing.

In manual glue dispensing, operators are in continuous contact with adhesives and sealants — many of which are sticky, chemically irritating, or require solvent-based cleaning agents for hand cleaning. Some industrial adhesives also release fumes during application. Robotic dispensing removes operators from this exposure entirely, isolating them from direct contact with the substances while still allowing safe loading and unloading of parts at designated operator stations.

Yes. One of the cited advantages of robotic glue dispensing is flexibility for new variant addition. The robot’s dispensing path is defined by its program, so a new product variant requires a new program rather than a hardware change. This makes it practical to run multiple variants on the same cell and to add new variants in the future without major reconfiguration.
The key inputs are the component type and dimensions, the adhesive or sealant being applied (type and viscosity), the dispensing path required (planar or 3D), the required production volume (parts per hour), and whether quality monitoring (vision or laser bead inspection) is needed. Details about the operator interface, part feeding method, and any safety or cleanroom requirements also inform the cell design.
