Factory halls cost money, resources and energy. The larger the more. To save space, machines have to be built more compactly. Critical factors tor this are smaller and lighter drive components. Thus less dead weight ist moved and energy counsumption is reduce accordingly. This is where the LINAX® linear motors axes are deployed. This application shows the screw fixture of a mobile phone with 2 parallel screw-heads. Buil up as a precise 3-axis portal robot. The control of the XENAX® Ethernet servo controller takes plaxe via a Beckhoff SPS.
Two Linax linear motor axes are arranged one directly above the other. Thereby the lower linear motor axis is integrated at an angle. Through appropriate interpolation via the UNAX axis interpolator it becomes possible to perform a vertical movement.
Basically any required geometry on the XZ-plane can be produce in this way.
If there is a power failure, the Z-plane travels downwards with no risk of collision.
The universal robot for fluid dosage was built up with 3 LINAX® linear motor axes. The 3 axes are each controlled by one XENAX® Ethernet servo controller. The XENAX® servo controllers have different IP-addresses and can be thus controlled from a computer through a conventional Ethernet switch.
The vertical linear motor axis operaties with pneumatixc mass compensation. With a small pressurestat the compensation force can be adjusted steplessly.
This robot is programmed for microtiter plates with 384 wells in a 16 x 24 grid. The dosage head consist of 8 parallel-switched magnetic valves. This way all 384 wells can be "filled" in one single to and from movement.
The X-linear motor axis travels at a constant speed across the microtiter plate. The special challenge lies in the real-time control of the valves during the run. This precise timing results directly from the powerful processing of the UNAX® axis interpolator.
The handling machinee consists of a total of 9 LINAX® linear axes. Various small plastic parts are automatically assembled and laser labelled. They are controlled with a WAGO SPS via Ethernet TCP/IP by means of a switch to the XENAX® Ethernet servo controllers.
The modular laboratory platform allows biologists and chemists to apply new technologies within the shortest possible time. The process module library, which works with components from different vendors, plays the key role here.For the vertical movement of the modular LINAX linear axes with mass compensation have been used. Thanks to its compact dimensions the XENAX® servo controller could also be "packed" directly into the process modules.
2 LINAX linear motor axes are directly positioned with dowel pins in an XY arrangement and bolted together.The small vertical Z-axis is fixed on to a sturdy "boom".
In standalone iperation, the 3D geometry is stored on the UNAX® axis interpolators. The programming is carried out on the supplied "Motion perfect" tool in a simple BASIC-like syntax. The circle interpolation consists e.g. of only a "one-liner".
Computer mice need to work on a veriety of surfaces. This puts stringent demands on the optics. Using a compact XY table consisting of 2 stacked LINAX® linear motor axes the optimal parameters for the optical mudule are determined.
The linear motor axes are controlled with a PC via Ethernet TCP/IP connection to both XENAX® servo controllers.
The Fraunhofer Institute breaks new ground in nonliter dosage. In this process the liquid is "pulsed" thorugh a fine hole only a few micrometres wide. Due to capillary axtion of the fluid no closing valve is necessary. Using the upsie down XY linear motor axes the utrasonic impulse-head is guided to te "fluid sources" and the dosage is triggered. If mnow the "target microtiter plate" is also positioned in the XY direction, each "well" can be individually and flexibly dosed.
Simple design of the portal robot with a LINAX® Lxe 400F40 as X-axis. Vertically mounted on this with an adapter plate the Lx 176F40 as the Y-axis. Using centering pins the Z-axis Lx 85F10 with mass compensation is directly screwed to the Y-axis.
Each axis is connected to an XENAX® Ethernet servo controller. The 3D space curves are stored in the superordinate UNAX® axis interpolator. The process is started with an input pulse. Alternatively, the UNAX® axis interpolator could be flexibly controlled via instruction set from a PC or a PLC.
The semi-automatic machine inserts single pins into a connector housing. Here, the "solder slot" is captured by the camera and aligned before placement of the pin. The machines had to be bzilt up in a space-saving manner. The compact LINAX® linear motor axes were predestined for this. These precisly move the connector housing to the pin position. All axes, including the rotary ones, are controlled by XENAX® Ethernet servo controllers.
A superordinate SIEMENS S7 is running via a multi-channel switch and Ethernet TCP/IP.
