An apparatus is provided with a component feeding member for feeding electronic components having lead wires in a tape-bonded state, an insertion head for separating the electronic components fed from the feeding member from the tapes and inserting to holes of a board, and a fixing head facing the insertion head via the board for cutting and folding the lead wires of the inserted electronic component in the board thereby fixing the electronic component to the board. AC servo motors operating independently of each other are individually set in the insertion head and the fixing head, which are controlled by a device so as to be synchronous with each other.

Electrical circuit trimming methods. In one aspect of the invention, a trimming method includes assembling one or more components of an electrical circuit onto a printed circuit board having one or more electrical connections coupled to the said one or more components. An electrical parameter of the electrical circuit is then trimmed. The trimming of the electrical parameter of the electrical circuit includes removing a portion of the printed circuit board to break the electrical connection on the printed circuit board. In another aspect of the invention, the trimming the electrical parameter of the electrical circuit includes electrical programming of the electrical circuit.

An apparatus and method are provided that increases the efficiency of material handling apparatus, such as those used to trim and form electrical leads on solid state electrical devices. The apparatus includes a plurality of rotatable pulleys, an endless belt capable of retaining devices to be processed that is disposed around the pulleys such that rotation of the pulleys will cause said belt to travel around said pulleys, and a plurality of paired tooling members, each of said, paired tooling members having first and second tooling members disposed on opposing sides of the belt and directly opposing so as to cooperate and perform a tooling operation on the leads when reciprocated toward each other along a common axis. In a preferred embodiment, two horizontally aligned pulleys with vertical axes of rotation are used to rotate the belt in a horizontal plane. The electrical devices are contained in a lead frame which is retained by pins on the belt which pass through indexing holes in the lead frame and the faces of the electrical devices are vertically oriented. The first and second tooling member are horizontally reciprocated by a common cam to perform the tooling operations on the electrical devices and the rotation of the belt is synchronized with the reciprocation of the tooling members. Alternatively, the first and second members can be driven by different cam drives that are synchronized in conjunction with the rotation of the pulleys and the relative orientation or the pulleys, the belt, and the electrical devices can be varied to accommodate specific tooling or spacing requirements.

Sensor arrangements are provided to detect whether initial and final wire leads were properly terminated to tang terminals of dynamo-electric machine components. The sensor arrangements may detect whether excess wire from the termination of the initial wire lead is present on a first side of a wire gripper. The sensor arrangements may detect whether excess wire from the termination of the final wire lead is present on a second side of a wire gripper. The sensor arrangements can include two sensors or a single sensor to detect the presence of the excess wire. Beam sensors, vision sensors, or tactile sensors may be used to detect the presence of the excess wire. A plunger device is provided to facilitate the tearing of thin initial and final wire leads to a tang terminal of a commutator.

A tool cartridge for seating and cutting a communication wire in a terminal block. The cartridge includes a tool end and a base end. A wire seating blade and a wire cutting blade extend outwardly from the cartridge and are mounted for longitudinal movement relative to the cartridge and to each other. A spring bias detent assembly forces the wire seating and wire cutting blades into contact with each other for longitudinal movement together relative to the cartridge. A compression spring resists longitudinal movement of the wire seating and wire cutting blades in the direction of the base of the cartridge by seating pressure applied to the cartridge. A cam is positioned to release the detent assembly thereby disengaging the wire seating and wire cutting blades from movement together after a predetermined compression of the compression spring. The release of the blades from movement together permitting the compression spring to drive the cutting blade to its cutting position to cut the wire.

There is provided an apparatus for bundling a plurality of wires placed on a receiving plate. The apparatus is provided with a bundling pawl mechanism that includes a plate and a pair of pawl members. The pawl members are respectively supported at pivot points provided on the plate in spaced-apart relation and interconnected with driving units for opening and closing movement. The pawl members also respectively extend beyond an edge portion of the plate. A wire bundling region is formed between inner surfaces of the pawl members and the edge portion of the plate when at least one of the pawl members rotates toward the other of the pawl members in a closing direction. The bundling pawl mechanism further includes a wire catch prevention member that projects into the wire bundling region from an angled inner corner formed between the inner surface of the at least one pawl member and the edge portion of the plate when the at least one pawl member rotates in the closing position. With the above construction, since the wire catch prevention member projects into the bundling region from the inner corner, even if the angle of the inner corner becomes acute as the wire bundling region becomes narrower, the wires can be prevented from becoming caught in the angled inner corner, thereby preventing the wires from becoming damaged in the angled inner corner.

A wire crimping apparatus includes a pair of wire-length setting rollers, a pair of crimping cylinders arranged in a direction of feeding a wire, a pair of wire guides which are openably/closably attached between said pair of crimping cylinders, a pair of moving tables which has connector container grooves opposite to said pair of crimping blades and can move independently of a direction horizontally orthogonal to a wire, and a wire guide stand which has a wire pushing-down cylinder and can move in the direction vertically orthogonal to the wire. On a pair of moving tables, each wire is crimped to the connector on a first moving table at a forward position in the direction of wire feeding, is extended to have a required length between the moving tables by the wire-length setting roller, crimped to the connector on a second moving table at a backward position in the direction of wire feeding, and the moving tables are moved in opposite directions to connect wires between the connectors in a crossing manner.
