Selecting a DriveSet for a bonding robot

Utilizing bonding robots is but one application for which DriveSets are being used successfully. How fast and simple it is to select the suitable positioning system in such a case is demonstrated here. This example is based upon the following customer's requirements:

Workspace Complex contour in the range of 50x60 millimeters
Dosing device to be moved 1 kilogram
Pulse time for running the contour 4 to 5 seconds (~0,2 meters per second) for constant path velocity
Desired precision 0,1 millimeters
   

Simple, quick, efficient: The selection-wizard

Selection of the DriveSet M208

These few considerations are enough to select the appropriate DriveSet with the interactive selection-wizard at www.drivesets.de. First of all, you need to decide on the workspace for which the DriveSet is to be selected. You can choose from three selection diagrams. Because the dimensions "longitude" and "latitude" are enough to describe the bonding robot’s workspace, you call up the diagram for the workspace Plane.

The diagram already displays the most important operating parameters of the various DriveSets. On the x-axis, the velocity classes are indicated, on the y-axis the load-capacity classes. At the intersection points, you will find the DriveSet types with these characteristics. The 0.1 millimeter precision class is displayed in white script on a black background. The black script on a white background shows the DriveSets in the 0.025 millimeter precision class.

Because an average speed of 0.2 meters per second must be reached, you select the next highest velocity class of 0.4 meters per second. The dosing device for applying the bonding material weighs 1 kilogram. Consequently, you decide on the 1-kilogram load-capacity class.

After you have entered the values for the velocity and the load-capacity class in the selection wizard, four DriveSet types appear as alternatives. Because the DriveSets with the white backlighted numbers denote the 0.025 millimeter precision class, the selection is immediately reduced to two options. And the selection wizard helps you limit the selection even further: each DriveSet displayed in the half above the intersection points stands for a DriveSet with outrigger construction, the DriveSet types in the lower half are portal constructions. To run the bonding robot with complex contours, an outrigger construction is especially suitable: Correspondingly, a click on the DriveSet type DriveSet M208 is called for.

 

Fine parameters in the data sheet

Details in the datasheet

Up to this point, the length of the DriveSet’s trajectory path which this bonding robot requires has not yet been established. This setting is now entered directly into the data sheet. In the data sheet, an almost unlimited linear profile length can be set. In this concrete case, it will be adapted to the trajectory workspace and the integration environment.

The selected DriveSet M208 is a two-axis system in outrigger construction used for horizontally or vertically positioning very fine loads at normal velocity. It can be used both horizontally as well as vertically. The kinematics consist of linear units driven by a cogged V-belt and a suitable stepping motor. Propulsion of the first axis is provided by the carriage. Different variants of controller are possible, including the one most suitable for the constant trajectory operation needed by the bonding robot.

With the data sheet’s configuration possibilities, the DriveSet can now be even further adapted to the specific application environment. Among other things, that involves the configuration of the energy supply, the equipment of the control unit, integration into another controller environment, and the software package to be supplied. The capability for continuous path control is also selected in the data sheet, for the DriveSet M208 is also suitable for point-to-point positioning.

 

Without project engineering in less than ten minutes to the ideal positioning system

The bonding robot in use

Without any project engineering and in less than ten minutes, we have arrived at the ideal positioning system. In contrast, conventional methods would have required several hours of work for the project engineering of such a system. The DriveSets selection wizard has reduced the selection process to just a few steps. In less than ten minutes, the positioning system has been appropriately configured and can now be ordered directly.

For this bonding robot, the DriveSet M208 proved itself to be an excellent choice. Of course, when it was delivered it was completely mounted and run-ready. In the shortest amount of time, it was put into service. In the production process, it made the application of the bonding material so consistent that a solid bond between the workpieces was assured. The illustration displays the finished robot with its integrated DriveSet.
