However, at this time, the XY table on which the printed circuit board is placed can be replaced. return to a possible position (generally the origin position of the coordinates). a certain amount of time at this point Run the airflow blowout. This will prevent the electronic components from blowing up during insertion. This can be done without considering the removal of chips or chips. It is also possible to operate it manually. However, if the electronic component insertion operation is cannot be executed when When the insertion operation is stopped (offline operation possible state) ) Press the operation button etc. to make it eject for a certain period of time. Dispose of lead wires, chips, etc. that have been removed after cutting electronic component lead wires. The inside of the cutter body can be sucked toward the ejection side in order to Suction and air jetting from the air blowing hole 21 are carried out at the same timing, By setting the suction volume to be slightly larger than the jet volume, it can be removed from the lead wire insertion hole, etc. Moreover, chips can be discharged smoothly without air blowing out.
