ISMECA sealing adjustment FST

ISMECA sealing adjustment FST Report Customer Support Date: Monday, 07 November 2005 From: Mirko Eggenberger / CSU Concern: Sealing adjustment procedure for FST All sealing adjustments need to be done in production mode. 1. Before starting the adjustments unscrew the set screw and its blocking screw 2. They are 4 different position of the sealing head to set Front view Side view Top view C A B D Remove cover tape guide front and back Remark: if you’re doing the setting you can just remove air pressure from module and push manually the sealing head down.

Sealing pre-adjustment with gauges This can be used to make the pre-adjustment for the sealing head , Sealing shoe (gauge) , Plate to be mounted instead of the tooling (gauge) , The two dowel pins have to match with the holes on the gauge plate. To have more details on how to adjust see below. st 1 adjustment to check is “B” The dowel pin is the rotation centre Ensure the gap is more less parallel and has to be within 0.8 to 1mm. It is possible that the gap is not parallel due to non centred rotation point. If misadjusted refer to point ”B” C:\convert\temp\1284292963.doc 09.09.2015 2 / 7 Report Customer Support 4. Adjustment point “A” Good Not good Blocking screw for Blocking screws adjustment screw Adjustment screw , Untight the 4 blocking screws , Untight the blocking screw for adjustment screw , Use the adjustment screw to place the bits on sealing shoe parallel to the tape guide track , Control adjustment (parallelism) with magnifying glass, if adjustment is good tight all blocking screws , After tighten the blocking screws control the adjustment again C:\convert\temp\1284292963.doc 09.09.2015 3 / 7 Report Customer Support 5. Adjustment point “C” Good Not good Not good Blocking screws Micrometric adjustment screw , Untight the 4 blocking screws , Adjust the bits on the sealing shoe to be centred on the tape guide track , Control adjustment with magnifying glass , Tight the 4 blocking screws , After tighten the screws control the adjustment again 6. Adjustment point “B” Blocking Adjustment set screw screws C:\convert\temp\1284292963.doc 09.09.2015 4 / 7 Report Customer Support , Untight a little bit the 4 blocking screws , Use adjustment set screw to shift the sealing head (allen key n?3) and ensure the same sealing force on both bits , You can control the adjustment when piston is in down position with a shim that you slide under the bits. You should have the same height on each side. , The second test possibility is to make some sealing and advance cycles and then analyse the tracks. , When adjustment is done, tight the 4 blocking screws (do not use extreme brute force to do it) , After tighten the screws control the adjustment again 7. Adjustment point “D” 7.1 calculations Calculation for distance between sealing shoe and tape guide when sealing head is in down position and hot. This example is for 8mm carrier tape: Carrier tape thickness + cover tape thickness + 0,3mm 0 / +0.1 => 0.25+0.05+0.3 = 0,6mm 0 / +0.01 , Raise the sealing head to its down position (through I/O) , Control the gap you have between sealing bits and tape guide , To adjust the gap Blocking screws Adjustment screws C:\convert\temp\1284292963.doc 09.09.2015 5 / 7 Report Customer Support , Untight the blocking screws , Adjust the height with the adjustment set scews , Tight the screws , After tighten the screws control the adjustment again 7.2 inclination adjustment , Control if the 4 corners on the sealing shoe do have the same gap between bits and tape guide , To adjust Adjustment set screw To access the right blocking Blocking set screw screw it would be easier to remove the cutter. Before removing the cutter mark its position with a pen. , Untight the set screws , Use the corresponding set screw to adjust the same height under the two sealing bits , 0,6mm shim should pass without problem under the sealing shoe but 0,8mm shim should not. , Tight the screws , After tighten the screws control the adjustment again , Control again part 7.1 8. Final control , Pull carrier tape and cover tape to have unsealed part under the sealing shoe , Make a single manual cycle , Pull it out manually and control the tracks Remark: As we did a single sealing cycle the tracks will not be so strong but the 4 corners do have the same size and same strength. C:\convert\temp\1284292963.doc 09.09.2015 6 / 7 Report Customer Support If the sealing is still not perfect restart the at one of the item included between 4 and 7 9. Tight the set screw 10. Sensor adjustment Dowel pin Sensor , Raise down the sealing head (gap = 0,6mm 0/+0.1, see point 7) , Untight the dowel pin fixing screws , Move down the dowel pin till the sensor detects and move it up to the point that sensor does not detect it. , Tight the dowel pin fixing screws , The sensor should detect in a range of 0,3mm (carrier tape and cover tape thickness) and 0,6mm 0/+0.1 C:\convert\temp\1284292963.doc 09.09.2015 7 / 7
