Not only the proper selection of raw materials is decisive for a consistently high quality in sealing, gluing and potting of filters, but also the safety and accuracy of the production plant, which has to ensure a precise application process of the material to the parts. For this, the low-pressure mixing and dosing systems from Sonderhoff Engineering stand for.
The design of the dispensing cell SMART-M is modular and it is flexibly adaptable to different production concepts. Subsequent modifications can easily be realized with low planning effort. Due to the small outside dimensions of 1200 x 1700 x 2400 mm (width x depth x height) the cell has a minimal foot print. The 3-axis linear robot scans parts with a traversing range of up to 500 x 600 mm (width x depth) and up to a part height of 250 mm at the most. In doing so, the mixing head of the dispensing cell is positioned with a repeat accuracy of +/- 0.05 mm above the part. By this the sealing material can be applied through the mixing head dosing nozzle directly onto the part precisely to its contour or in a groove by. A maximum acceleration of 5 m/s² in the part radii is possible with the Sonderhoff linear robot.
At the Sonderhoff booth the feeding of parts to the dispensing cell is done user-friendly by means of a rotary indexing table with a 180° partitioning for an insertion and a work position turning within 1.5 seconds. For this semi-automatic part feeding the access of the insertion area at the cell is secured by a light grid. Alternatively, the parts are fed manually through the cell front, by a worktop or fully automatic via a transfer belt running through the cell.
