Abstract: An apparatus for automatically mounting electronic components on printed circuit boards has an insertion head which is adapted to rotate on an engaging shaft within a rotary bearing and be guided in the extent of rotation by means of a steel ball. Only the engaging shaft rotates and the position from which the components are supplied to the insertion head is stationary, the space needed for the inserting apparatus can be kept small. The bearing can be changed or the position of the bearing changed to change the insertion angle of the component relative to the printed circuit board, thus making possible various arrangements of the components on the circuit board.

Abstract: An apparatus for carrying electronic components from a supply position to an electronic circuit board or the like and placing the electronic components on the electronic circuit board or the like, which has a rod provided at its tip end with a suction tool for picking up components to be carried and which is connected with an air suction apparatus; a body frame supporting the rod for movement of the rod in the vertical and horizontal directions; two pairs of position regulating pawls which are movably supported on the rod and are supported for freely opening and closing to grasp the components from different directions which the components are held by the suction tool and positioning them; and an arrangement for opening and closing the position regulating pawls.

Abstract: This invention relates to a device for feeding or retrieving sheet boards, to be used in an apparatus for planting various electric parts or materials such as capacitors, resistors, connecting wires, terminal pins, etc. into sheet boards such as printed circuit boards. The device is designed that said sheet boards are automatically brought to a processing position for planting said parts or materials thereto, or after such processing there, such processed sheet boards are automatically retrieved from said processing position. This invention especially strives to keep said sheet boards free from damage or loss of planted parts or materials when feeding and retrieving them and to permit said device to treat different sizes of sheet boards, as well, at an evenly efficient speed.

Abstract: A process for mounting electronic parts of very small size on electronic circuit boards or substrates, in which the substrates are maintained in predetermined relative positions, and a dispenser unit dispensing a bonding material for bonding the electronic parts to each of the substrates, a mounting unit mounting the electronic parts on each of the substrates, and/or an inspecting unit inspecting the position and/or the electrical properties of the electronic parts mounted on each of the substrates are disposed in the same relative positions as those of the substrates to carry out their individual functions on the associated substrates, so that the electronic parts can be efficiently and rationally mounted on the substrates.

Abstract: Detachably mounted on a sliding table are a plurality of part tape or belt feed units each of which intermittently feeds to a lead wire cutting station a part tape or belt holding a large number of parts of the same type, each of which has lead wires extended in opposite directions and coaxially of a main body of the part and attached adjacent to their ends to parallel strips of tape or belt in equidistantly spaced apart relationship with the lead wires of the adjacent parts. The sliding table moves in either direction so that the desired part tape or belt feed unit is moved to a part feed position at which the desired part tape or belt feed unit feeds the part to the cutting station. At the cutting station a cutter unit cuts off from the part tape or belt the lead wires of the part, thereby separating therefrom the part having lead wires of a predetermined length, and the lead wires are bent in the same direction.
