Machine for mounting electrical components onto printed-circuit boards

Claim 2

Apparatus for inserting the connecting wires of successively arranged electrical circuit component parts on a feeding tape into matching holes of a circuit board, said connecting wires extending in a same direction from said feeder tape, comprising: a mounting bracket rotatable about an axis along which the connecting wires are inserted into said matching holes; means for fixing said bracket in an arbitrary position with respect to said axis; means mounted on said bracket for intermittently advancing said feeder tape; a cutter mounted on said bracket and operable to successively cut off the connecting wires of each of said component parts in response to each intermittent advancement of said feeder tape; an insertion head operable to reciprocate along said axis and rotatable with said mounting bracket to take up said arbitrary position and including a first gripper operable to rotate, during the time when said insertion head is moved downward, from a first position in which the gripper holds the cutoff component part to a second position in which the connecting wires of the held component part are substantially oriented toward said matching holes; and a second gripper disposed below said insertion head and operable to reciprocate along said axis in directions opposite to the directions of movement of said insertion head for holding the connecting wires that extend through the matching holes to give a bend thereto.

Claim 3

Apparatus as claimed in claim 1, wherein said second gripper is rotatable about said axis, further comprising means for fixing said second gripper in an arbitrary position.

Claim 4

Apparatus as claimed in claim 1, wherein said first gripper is rotatable through an angle of 90 degrees from a horizontally oriented position to a vertically oriented position, and wherein said tape advancing means includes a sprocket located in a position with respect to said first gripper in said first position such that a component part proper is positioned between the gripping ends of said first gripper with the connecting wires extending between the cutting edges of said cutter in response to each intermittent advancement of said feeder tape.

Claim 5

Apparatus as claimed in claim 1, wherein said insertion head and second gripper are mounted on a same vertical axis, further comprising first and second cams mounted on a same rotating cam shaft for unitary rotation and first and second linkage means for respectively reciprocating said insertion head and said second gripper along said vertical axis.

Claim 6

Apparatus for inserting the connecting wires of successively arranged electrical component part into matching holes of a circuit board, said connecting wires extending in a same direction from a feeder tape, comprising: a mounting bracket rotatable about a vertical axis; means for fixing said bracket in a desired angular position with respect to said vertical axis; means mounted on said bracket for intermittently advancing said feeder tape; an outer shaft and an inner shaft axially slidably disposed in said outer shaft, said outer and inner shafts being respectively movable along said vertical axis and simultaneously rotatable about said vertical axis with the rotation of said mounting bracket; a pair of vertically extending slotted guides coupled to the lower end of said outer shaft for guiding the connecting wires of each component part into the matching holes; an insertion head coupled to the lower end of said inner shaft having a first gripper rotatably mounted between a horizontal position for holding a said component part and a vertical position for inserting the connecting wires of the held component part into the matching holes, and means for rotating said first gripper between said horizontal and vertical positions during the time when said outer and inner shafts are moved axially along said vertical axis; a cutter mounted on said bracket for cutting off the connecting wires of a said component part positioned between the gripping ends of said first gripper; a second gripper vertically slidably mounted opposite to said first gripper when in said vertical position and movable between a low position and a high position to hold the connecting wires of said component part that extend through the matching holes to give a bend thereto; and means for imparting a reciprocating movement to said outer and inner shafts and to said second gripper in directions opposite to the directions of movement of said outer and inner shafts.

Claim 7

Apparatus for inserting the connecting wires of successively arranged electrical component part into matching holes of a circuit board, said connecting wires extending in a same direction from a feeder tape, comprising: a mounting bracket rotatable about a vertical axis; means for fixing said bracket in a desired angular position with respect to said vertical axis; means mounted on said bracket for intermittently advancing said feeder tape; an outer shaft and an inner shaft axially slidably disposed in said outer shaft, said outer and inner shafts being respectively movable along said vertical axis and simultaneously rotatable about said vertical axis with the rotation of said mounting bracket; a pair of vertically extending slotted guides coupled to the lower end of said outer shaft for guiding the connecting wires of each component part into the matching holes; an insertion head coupled to the lower end of said inner shaft having a first gripper rotatably mounted between a horizontal position for holding a said component part and a vertical position for inserting the connecting wires of the held component part into the matching holes, and means for rotating said first gripper between said horizontal and vertical positions during the time when said outer and inner shafts are moved axially along said vertical axis; a cutter mounted on said bracket for cutting off the connecting wires of a said component part positioned between the gripping ends of said first gripper; a second gripper vertically slidably mounted opposite to said first gripper when in said vertical position and movable between a low position and a high position to hold the connecting wires of said component part that extend through the matching holes to give a bend thereto; and means for imparting a reciprocating movement to said outer and inner shafts and to said second gripper in directions opposite to the directions of movement of said outer and inner shafts.
