Patent ID: 8407886

Claim:
A lead wire implanting apparatus comprising: a vertically movable tamping member having a through hole for inserting therethrough a lead wire to be connected to a brush main body; and a storing cup for storing conductive metal powder and having, in a bottom portion thereof, an opening for inserting therethrough the tamping member, the lead wire implanting apparatus configured to: arrange the brush main body at a position below the storing cup so that an implanting hole for implanting therein one end of the lead wire faces upward; after inserting one end of the lead wire into the implanting hole of the brush main body, elevate the tamping member to a first elevation position at which a lower end face of the tamping member is above the opening of the storing cup and drop the conductive metal powder around the lead wire inserted in the implanting hole; subsequently lower the tamping member from the first elevation position to tamp and press-fit the conductive metal powder; and perform the tamping action of the tamping member a predetermined number of times, whereby the lead wire is implanted and fixed to the brush main body, the lead wire implanting apparatus characterized by comprising: a first servo motor serving as a drive source for driving the tamping member in vertical directions; a first position detector for detecting a shift position of the tamping member; and controlling means for controlling the first servo motor based on detected information by the first position detector so as to cause the tamping member to perform a predetermined tamping action, wherein the controlling means servo-controls at least a tamping speed and a tamping pressure so as to match preset target values so that the tamping member performs the predetermined tamping action.
