- the second embodiment shows a method for automatically inserting signal lines 14 and 14 attached to a head assembly 17 into insulation protection tubes 30 and 30. .
- the insulating protective tubes 30 and 30 are used to protect the fixed portions of the signal lines 14 and 14 to the suspension 6, and are fixed at predetermined positions in the automatic suction nozzle 31 by a jig (not shown). Are located in The automatic suction nozzle 31 can sufficiently draw the terminals of the signal lines 14 and 14 into the terminal by suctioning the surrounding air.
- the separator jig 34 is a separating member for separating the two intertwined signal wires 14 and 14 and inserting them into separate insulating protection tubes 30 and 30, respectively.
- the plate jig 33 is an auxiliary jig for inserting the separator jig 34 between the two signal lines.
- the automatic suction nozzle 31 is brought closer to the signal lines 14 and 14, and the signal lines 14 and 14 are drawn into the hollow portion of the automatic suction nozzle 31 by suction. Inhale. At this time, the signal lines 14 and 14 take a linear posture along the flow of the air sucked into the automatic suction nozzle 31. However, the tangled state of the two signal lines 14 and 14 is Not resolved.
