Bubble-free dosing of UV adhesive

Touch screen use no doubt is part of our everyday life that includes - Smartphones, tablets or even modern day kitchen devices are operated through touch screens.

Each touch screen is glued on a transparent part of the component housing to ensure visibility and protection of the screen. The UV adhesive itself and the technology to perform the gluing application have special requirements including UV adhesive that must be applied without bubbles to the surface. The amount must be precise to supplier specifications with the process easily repeated. Our customers use mzr-pumps of the modular series configuration to perform this gluing task, where the pump can be easily integrated into existing systems utilizing a variety of interfaces.

As an example, dosing can be performed through an automated robot, with synchronous doses with every movement of the robot.  The full-surface gluing of the displays includes an important requirement to apply the adhesive in a defined and timely. This process also enables subsequent cleaning, provides a small pump foot print, precise bubble free dosing utilizing our mzr-gerotor style gear pump a significant advantage.
