The Advantage

The Customized 3-in-1 Automotive OCV Levelling Machine is designed for pre-check of open circuit voltage and checking of under- and over-filling of sulphuric automotive batteries. The individual batteries supplied through the conveyor of the finishing line are exactly positioned. The fill stroke moves down, and the levelling heads are lowered into the filling holes of the battery. The first station checks the acid level in the battery. If a battery is under-filled it will be topped-up to the level, if a battery is over-filled it removes the acid out of the battery with diaphragm pumps. As a result, the acid level is accurate in all the individual cells by means of hose sensor monitoring. The second station will check the levelling unit by lowering the Check heads with a distance measuring system until each tungsten electrode gets in contact with acid. The result will be displayed on the HMI for verification. An exact level achievement is guaranteed. If a battery fails it will be rejected on a reject table.

It combines an OCV test, acid levelling and an independent level check for automotive car and truck batteries. The OCV test checks the open circuit voltage before filling, and all functions are operated from one touch panel. The OCV test is also available as a single machine: OCV Test Machine.
The levelling heads are lowered into the filling holes. If a battery is under-filled, it is topped up to the level, and if it is over-filled, 6 diaphragm pumps remove the excess acid into the drain system of the factory. Hose sensors at the suction tubes of the heads control the levelling process.
A distance measuring system lowers the check heads until each tungsten electrode is in contact with acid. The filling level of each cell is shown on the HMI for verification, and batteries that fail are rejected onto a reject table.
The level accuracy is ±2 mm of the final level. The machine handles batteries from 20 to 70 kg at up to 6 batteries per minute, depending on battery size and as long as the batteries are not over-filled. An optional distributor for different acid densities can be installed and pre-programmed.
