A desktop automated dispensing system is designed to provide computer signal-controlled dispensing. The ability to connect your robot to a computer or T-box controlling panel simplifies programming regardless of you are dispensing dots, lines, circles, arcs, or compound arcs.
Furthermore, this computer signal-controlled feature enables the dispensing system to integrate every other functions easily. The closed-loop motor and linear encoders, CCD fiducial recognition, and laser height sensing of the substrate allow the system to adjust programs to automatically compensate for both surface height changes and variations in product orientation.
With an automated dispensing system, the output tool is also variable:

And other types of dispensing devices. This allows manufacturers to incorporate robots because they can be adjusted to fit a wide variety of applications from inline to batch dispensing.
FEATURE
PROGRAMMING METHODS
Our desktop dispensing robot could be easily programmed by two methods using PC or Teaching Panel.
Teaching Method comes with Teaching software, will not include vision function so to be known as a more economic option. This technology is integrated with a Teach Pendant, an intuitive handheld controller that allows for quick setup and easy, on-the-fly programming.
Robots that come equipped with vision will use our DispenseMotion software. This software is powerful and intuitive and integrates easily with the camera. This vision-based programming works well for complex paths and allows users to program quickly with just a few clicks.
VISION SYSTEM
Dispensing robots with vision allow on-screen preview of the dispensing path to make programming easier. All the user needs to do when programming is to indicate a point on the screen where the dispensing pattern begins, outline the path to follow, and indicate where the cycle ends, and the software takes care of automatically aligning the camera and orienting tip offsets.
HEIGHT DETECTION
Some dispensing robots can measure the height of each dispense location on the workpiece. The data gathered by the Z clearance can then be used to adjust for height variations from one workpiece to another. Our all-product line can be upgraded to use mechanical height detection, which requires a device that contacts the workpiece and determines the height of a single point at a time. The PRO/PROPlus Series is our only robot that utilizes laser height detection instead. This version of height detection is perfect for fragile substrates, and it can also determine the height of multiple points on a workpiece in a single sweep.
TIP DETECTION
All PROSTECH robots can offer automatic tip adjustment, meaning that with every dispense tip change, the system will recalibrate and adjust the X, Y, and Z height to make up for any discrepancies. This will ensure deposit accuracy, every time.
Although this is an optional add-on to our robots, our tip detector is compatible with our product lines. The tip detector operates by touching the tip on a sensor pad to detect the height location of the tip and then makes a deposit on the tip detector to confirm the XY location, automatically adjusting the program as needed.
Furthermore, another product line uses the tip aligner which uses optical sensors to detect the outside diameter and end of the dispense tip. Any discrepancies in the gap height are identified and the offsets are automatically applied.
TYPE OF DESKTOP DISPENSING ROBOTS
Economic Desktop Dispensing Robot is the perfect entry-level solution. It allows users to dispense in complex patterns and is a great upgrade from benchtop dispensing.
High productivity Desktop Dispensing Robot
 | is designed with the added working area (dispensing bed) and output tools (valve, barrel, and syringe holder/ Z axis) for better performance with medium and large production. |
Rotary Desktop Dispensing Robot
 | offers the perfect solution when a fourth axis is needed to dispense in any dimension and at any angle. This allows users to dispense along the 360° rotation plane without sacrificing accuracy in the placement or volume of the deposit. It simultaneously moves along the X and Y axes during every dispense cycle and only the R axis needs to be set for easy and quick programming. |
Vision Desktop Dispensing Robot
 | includes a CCD smart camera that allows multi-point focus on variable heights. The fourth axis enables users to navigate intricate arcs and curves with true 3D motion control. It also allows single-fixture operation, which reduces cycle time and cost. |
Customizable Desktop Dispensing Robot
Further options added to the standard desktop robot:

Although desktop automated dispensing systems may require a larger investment upfront, the accuracy, increase in production, a decrease of product rejects, and overall capabilities bring so much value to a manufacturing line. Our dispensing robots often provide a return on investment in a matter of months.
