Robotic Container Lab for Lollipop Sample Preparation & OES Analysis
is fully automated and shall be used for sample preparation for rapid and accurate analysis of Metal samples without any manual intervention.
It shall basically consist of sample introduction facility, automated sample preparation system, master control system, automated software, robot system, vision system, Optical Emission Spectrometer, sample holding system, sample identification marking system and sample storage system.
All the above laboratory components are integrated within a room having a size 10’X20′ provided by client. The operator shall place the steel samples into semi automated tail cutting machine placed outside the Container Lab. The operator will inspect the sample for having proper shape and size, in case there are fins around the sample periphery, the operator will grind the sample to obtain smooth surface in the periphery to facilitate proper grip by the Robotic gripper arms. A pedestal grinder is provided outside the Container lab near pin cutter.
The operator places the OK sample (after cutting the tail and smoothening the periphery of the sample) at the sample entry station called the input station of the Container laboratory, the sample identification is fed in the HMI manually and activates cycle start instruction. The sample shall be picked up by Robot and shall be placed in the automatic milling machine where the sample preparation shall be performed.
After completion of sample preparation (milling the surface), the robot shall carry the sample to vision system to identify the good surfaces (points) by image analysis. After the image analysis through vision system the robot places the sample at spark stand of OES by coinciding right spot w.r.t. spark electrode. After first spark the robot positions the sample for second spark at the second pre identified spot. If the analysis matches the desired levels the analysis is considered as over otherwise the robot will place the sample for the third spark and so on, any two analysis should match to declare the result if not the sample will be declared as bad sample.
The sample shall be handled from one spark position to the next position by means of robot system. After the analysis is over, the result will be automatically transmitted to the predefined destination for the user for further transmission as desired. Finally the sample shall be passed to the storage bin after automatically printing the identification of the sample for future traceability.
The complete analysis device shall be cleaned & the spark stand shall be sealed automatically to avoid contamination by incoming air, when there is no cleaning activity.
