A transfer rackloaded with a seriate number of component supply cassettesto be handled collectively is carried and retained on a truckso that it can be taken in and out of the truck. The transfer rackis passed between the truckand a component supply section. Thus, the withdrawal of the transfer rackfrom the component supply sectionto the truckand the delivery of the transfer rackto the component supply sectionare executed in a timely manner so as to change the component supply cassettesat the component supply section 8. The transfer rackdelivered to the component supply sectionis positioned by operating an automatic positioning means at the component supply sectionin a direction in which it is loaded and unloaded and in a direction perpendicular to the direction in which it is loaded and unloaded.

A nozzle rod is formed by fixing a thick diamond chip to a tip of a nozzle pipe made of a super hard metal, the other end of the nozzle pipe is thinned and the nozzle rod is joined with a shank by way of this end, a tip of the nozzle rod and vicinities thereof are so shaped as to have a predetermined sectional shape, a center hole is formed in the diamond chip by wire electro spark machining and expanded for forming a nozzle slot having a nozzle opening consisting of a center slit and &ldquo;U-shaped&rdquo; slits which are disposed symmetrically on both sides of a longitudinal direction of the center slit, thereby composing an electronic part adsorbing nozzle. This construction enables it to provide an electronic part adsorbing nozzle which is economical and excellent in durability.

Manufacturing method for an electronic part absorbing nozzle

The apparatus comprises a reciprocal blade (,) having edges (,) respectively set at a side of a forward end and at a side of a return end of reciprocation, and fixed blades (,) having edges respectively set at the side of the forward end and the return end to cooperate with the edges at the forward end and the return end of the reciprocal blade. The reciprocal blade and the fixed blades cooperate with one another to cut a carrier tape with a shearing force. Partitioned carrier tape storage parts (,) are disposed below respective shear parts formed between the edge at the forward end of the reciprocal blade and the corresponding edge of a fixed blade, and between the edge at the return end of the reciprocal blade and the corresponding edge of a fixed blade. When an emptied carrier tape (,), after a component is removed therefrom, is cut by the edge at the forward end or at the return end of the reciprocal blade and the edge of the fixed blade at the same side as the cutting edge of the reciprocal blade, the cut carrier tape is sorted and collected in the carrier tape storage parts in accordance with a kind of the carrier tape. The carrier tape can hence be sorted and collected for every kind thereof simply by changing a drive direction of the reciprocal blade in accordance with the kind of the carrier tape.

Electronic component feeding apparatus

A component supply apparatus for sequentially supplying components to a predetermined position by separating a covering tape from an accommodating tape. The components are accommodated in the accommodating tape at predetermined intervals along a longitudinal direction of the tape. The components are covered with the covering tape. The apparatus includes a reel around which the separated covering tape is wound. The reel includes a reel body having a winding barrel removably mounted on a driving shaft and a guide flange positioned at one end of the driving shaft and a guide flange positioned at one end of the driving shaft. An inelastic auxiliary ring is provided so as to wind the covering tape about the peripheral surface thereof. The ring includes a rotation preventing portion and is removably mounted on a peripheral surface of the winding barrel.

Component supply apparatus

A component supply apparatus includes a component feeding device for feeding components to a component feeding path, with the components arranged in a row while the components are being agitated by air, and a path forming member having a curved path extending from the component feeding path to a component supply position, for guiding the components fed from the component feeding path to the component supply position by changing a direction of each of the components by a predetermined angle. A plurality of air supply holes are provided at plural portions of the curved path for feeding the components fed to the curved path to the component supply position.

A lead clamping apparatus clamps and mounts to an electronic circuit board an electronic element having a plurality of leads which are arranged in two rows and are oriented in the same direction. The apparatus includes a plurality of pairs of clamping members arranged in the same direction as the two rows of leads, a support slidable in a direction perpendicular to the direction of pivotal movement of the clamping members to abut against a desired number of the clamping members, whereby allowing the same to perform a clamping action, a drive source for slidingly driving the support, a piston for opening and closing the clamping members through the support, and a pusher slidable in the same direction as the support and for biasing the electronic element to insert the same into the circuit board. Accordingly, it is possible to selectively use the clamping members, of which number corresponds with that of the leads of the electronic element. If there is a sufficient area in an electronic circuit board to receive an electronic element being mounted, the element can be mounted on the board irrespective of other electronic elements having been previously mounted on the board. Programming of production process, and design of electronic circuit boards can be greatly facilitated by the invention.

Electronic circuit element insertion apparatus

A component lead wire cutting equipment includes upper and lower levers for gripping a pair of lead wires of an electric component extending in the same direction. A driving device moves the levers. A pair of cutter blades are mounted on the levers to spread the pitch of the lead wires to a given size, and to cut off the lead wires. A pair of regulating convex portions regulate the movement of the lead wires along their spreading direction in the position between the cutter blades and the component body. During the cutting operation of the lead wires the component is prevented from being broken or from being inclined in its body.
