What Is a Desktop Dispensing Robot?
A desktop dispensing robot, also known as a tabletop coating robot or sealing robot, is a robotic device used to apply adhesives, sealants, coatings, and other liquid materials to specific locations with precision.
Applications of Desktop Dispensing Robots
These robots find applications in various production environments, particularly for coating IC substrates and other surfaces where precise liquid material application is necessary. They enhance efficiency by providing stable and consistent dispensing, improving overall work quality.
Principle of Desktop Coating Robots
1. Dispensing Robot
There are three main types of dispensing robots based on arm motion: vertically articulated, horizontally articulated, and Cartesian robots. Cartesian robots offer simplicity, high positioning accuracy, and lower installation costs.
2. Coating Method
Dispensing methods include the general air pulse method and mechanical methods like the JET method and the volumetric metering method. The choice depends on the liquid material’s characteristics, with the air pulse method offering easy control over dispensed volume.
Features of Desktop Dispensing Robots
1. High Versatility
These robots are adaptable to various production setups, making them suitable for high-mix low-volume production environments.
2. Automation is Possible
They can be easily integrated into automated processes, enhancing production quality and efficiency without significant process changes.
3. Easy to Install in Production Sites
Compact and flexible, these robots can be installed in existing production sites with minimal disruption, accommodating model changes and layout adjustments.
4. High Accuracy
Robust construction ensures high dispensing quality and stability, contributing to improved yield rates and consistent production outcomes.
How to Select a Desktop Dispensing Robot
1. Weight and Axis Load
Consider robot payload and axis load moment to ensure sufficient capacity for the dispensing application and associated equipment.
2. Accuracy and Repeatability
Assess the robot’s motion trajectory accuracy and repeatability to guarantee precise dispensing performance.
3. Controllability
Ensure that the robot’s control system offers precise coordination with the dispensing process, including speed, turning radius, and movement trajectory.
