Lightning-fast and accurate process control engineering ISEDD GmbH in Bielefeld developed measurement and inspection equipment, which are geared to the respective usage and the special requirements of customers. An exemplary development is the non-destructive thickness measurement of CD, DVD and BluRay matrices with the measuring system of MDM-8103. The measurement error of the featured instrument here is smaller, 0. 5 m at a sensor distance of up to 1, 8 mm and a measuring time of about four seconds per scan. Optical disk replication is usually done in the injection moulding process. The part of the injection molding tool with data information consists of a thin nickel matrix and is quick and easy to change. These matrices are made with high requirements in terms of the thickness tolerance.
The required tolerances in the clamping and vent area of the tool are especially close. The acceptable thickness deviation of the nickel plates is usually only 3 m. Lengthen the time necessary for the injection molding to great thickness variations and reduce so the productivity of the machines. The nickel matrices produced in a galvanic nickel deposition process, depending on the system is subject to fluctuations. With the thickness gauge MDM-8103 of the company ISEDD the dimensional accuracy of dies can be verified directly after the electroplating process quickly, precisely and reliably. The thickness measuring device scans the round nickel metal with capacitive displacement sensors and geometric assigns all of the matrix values.
The data is automatically compared to the good – bad sorting with Soll-Werten and displayed on a screen. Depending on the task and configuration, the matrix can be checked bort, suspecting or the critical radii of clamping and vent area. Differentiated limits can be set for the different areas of the object to be measured. In addition they can be used discovered quality information for assessing the reliability of the Galvanikbader and so in advance prevents Committee with this measuring device. The measurement is either automatically after recording the order marking or started with the touch of a button. The operation of the instrument during normal production requires no further intervention. The configuration is done either directly functions the device software via password-protected or for connection to a QM-system communication with the parent database connection and identification of each measurement object via barcode or QR code scanner or also via RFID labelling. The representation of the measurement results on the screen is designed according to the customer’s requirement. The inclusion of other instruments, E.g. Rauigkeitsmessung, is possible on request. The unit was integrated into the version of MDM-8100 in automatic production lines and communicates with the parent manufacturing control system and control of the production line. Can be specified for each nickel sheet to measure individual limits for the good / bad sorting and the measured values to the quality management system passed. Depending on the task, ISEDD used for the thickness measurement laser triangulation sensors, laser line scanner, optical micrometers, confocal optical sensors, Eddy current, or capacitive sensors. The software is adapted individually to the requirements of the application and enables a fast and highly accurate production control and process optimization.
