An insertion machine of the type used to form and insert the lead-wires of an electronic component into openings of a printed circuit board insertion machine comprising a frame and a head assembly. The head assembly receives an electronic component and includes means for forming the lead-wires into a predetermined shape and means for inserting the lead-wires into the openings of the printed circuit board. A clinching assembly is positioned below the head assembly and includes means for trimming the lead-wires and means for clinching the lead-wires. A work-support table for holding the printed circuit board is rotatable about a vertical axis and is positioned between the clinching assembly and the head assembly.

Electric component insertion apparatus

A clinching assembly for use with an insertion machine of the type used to form and insert the lead-wires of an electronic component into openings of a printed circuit board insertion machine. The clinching assembly includes two clinch heads that are selectively movable along a U-axis, parallel to the circuit board. Each clinching assembly is further selectively movable along a Z-axis, perpendicular to the circuit board. A single pneumatic actuator is used to raise and lower both clinch heads simultaneously. A T-shaped linkage attaches each clinch head with the single pneumatic actuator. Vertical movement of the pneumatic actuator is translated through the T-shaped linkage to vertically displace both clinch heads, and simultaneously, allow horizontal displacement of each clinch head, independent of the vertical location of the T-shaped linkage.

Clinch assembly lift mechanism

The geometric features of a supported component in a machine for mounting surface mount electronic components are either frontlighted or backlighted for inspection purposes. To backlight the features a fluorescent surface above the component is excited with UV light. Since UV light reflected from the component is invisible to the camera system, the features will appear black with a bright background. To frontlight the features, a light source is used which generates light outside the UV range and a) having a wavelength corresponding to the wavelength of the UV fluorescing surface so that no fluorescent is created or b) having a wavelength substantially different from the UV fluorescing surface that is absorbed by the surface without causing fluorescing to take place. This light when reflected from the features is seen by the camera and the features will appear bright in a dark background.

Machine for placing surface mount components

A cropping mechanism for a surface mount machine is disclosed which cuts the feed tape supplying electronic components. The displacement of an actuator in one direction between end positions cycles the cropping blade from a start location to the cutting location and back to the start location. The actuator has a cam which rides in selectively configured slots defined in opposed, pivotally supported levers which support a pin received by the cutting element and controlling its displacement.

Cropping mechanism for surface mount placement machine

The tool tip assembly has a fixed large tool tip and a movable telescoping tool tip which has a smaller area pick-up end. The telescoping tool tip is displaceable between fixed stops and the forward stop is defined by an annular bumper projecting rearwardly from the inner surface of the fixed tool tip proximate the forward bore portion. The telescoping tool tip can be quickly and conveniently accessed for repair, inspection or replacement by removing the molded elastomeric fixed large tool tip.

Tool tip assembly for surface mount machine

A DIP insertion machine is disclosed wherein the feeder, inserter, valve stack for the feeder and inserter and electronic distribution panels for the valve stack, feeder and inserter are all mounted on a single plate which is secured to a mounting bracket attached to the bottom of the cross-beam on which the component magazines and shuttle are secured.

Electronic component insertion machine

A machine for inserting DIP components. A DIP component slides down a chute and onto a mandrel. A thruster advances to thrust the component against a stop which is secured to the mandrel. The precisely located component is gripped and the mandrel is retracted, whereupon component insertion takes place.

An electronic component insertion machine includes an insertion head having a pair of finger assemblies which grip a component prior to insertion. Each finger assembly has an actuating lever secured to a pivot shaft and a finger holder releasably clamped to the pivot shaft. The actuating levers have surfaces which are maintained in engagement throughout their displacement so that rotation of one effects a conjoint rotation of the other and are displaced to advanced positions. The finger holders are then unclamped, oriented to their desired orientations relative to their actuating levers and then clamped in position.

A machine for insering DIP components has two adjacent insertion stations so that DIP components having two different sizes can be inserted. The inserted leads of a component inserted at either location are backlighted and a compound mirror redirects the component image to a selected portion of the imaging areas of a camera where the leads appear as two spaced rows of black leads.

A machine for inserting DIP components either into a circuit board or into sockets on the circuit board having two alternate heights. The insetion machine can be advanced a given distance by a fixed stroke cylinder, and the upper location of this stroke can be matched to the upper surface of the circuit board or to the top surface of either of the sockets by a cam which can be displaced horizontally to three distant locations.

A cut-clinch head having a movable and a fixed knife assembly for cutting and forming lead wires of electrical components which extend down through openings in printed circuit boards. The movable knife and the fixed knife are easily removed from the head assembly for servicing. Further, the fixed knife is a tubular member that has a cutting edge formed out of the axis of the tube.

Removable blades for cut-clinch head assembly

A mounting for a cut-clinch mechanism having separate elevator means for each head assembly for movement of the head assemblies on a vertical axis toward and away from a printed circuit board. The separate elevator means are carried on a common U-axis mounting that can move the head assemblies toward and away from one another to accommodate variably spaced component lead wires.

Cut-clinch mechanism

A head assembly for a cut-clinch mechanism that cuts and forms lead wires of an electrical component that extend down through openings in a printed circuit board. The assembly has a fixed knife and a movable knife driven by a pneumatic cylinder into cutting relationship with the fixed knife. The drive has a piston which encloses an electrical contact responsive to contact of the movable knife with a lead wire to signal the presence of the lead wire. The electrical contact is adjustable to fine tune the sensor.
