## Abstract

A device for mounting leadless chip-type electronic components on a substrate. A mounting head includes a slide which is displaceable in a guide in a single direction between a loading position and an unloading position, and a suction device which is displaceable in a vertical direction only at the area of the unloading position. A component to be mounted, dispensed from a magazine or from a carrier strip, is transported by the slide from the loading position to the unloading position where the component is picked up and then moved down onto the substrate by the suction device. As a result of the controlled displacement of the components in only two directions, accurate and reproduceable positioning of the component is achieved.

## Claims

### Claim 1

A device for mounting chip-type electronic components on a substrate, comprising a table, a mounting head fixed to the table, and means for positioning a substrate with respect to the mounting head, characterized in that the mounting head comprises:
a guide fixed in position with respect to the table, defining a single horizontal channel said guide having a vertical passage therethrough,
a slide displaceably mounted in said guide for movement along said channel only between a loading position and an unloading position, and having a recess for accommodating and transporting a component, said recess having a horizontal supporting surface and a vertical abutment face for engaging a component being transported in the recess,
a suction device moveably mounted to be displaceable in a vertical direction only, through said passage, and
means for displacing said suction device upward to pick up a component from the slide when the slide is in the unloading position; and then when the slide is moved from the unloading position, downward to move the component through said passage to position the picked up component onto a substrate positioned underneath the guide.

### Claim 2 (depends on 1)

A device as claimed in claim 1, characterized in that the device further comprises means for transporting and guiding a component carrier strip immediately above said guide past said loading position, and
the mounting head comprises a punch arranged for vertical movement at the area of the slide loading position, for moving a component from the carrier strip to the recess in the slide.

### Claim 3 (depends on 1)

A device as claimed in claim 1, characterized in that the mounting head comprises a magazine holder arranged for holding a magazine containing stacked components at the area of the slide loading position, and
the device further comprises means for transferring one component at a time to the recess in the slide.

### Claim 4 (depends on 1, 2, 3)

A device as claimed in claim 1, 2 or 3, characterized in that said suction device includes a suction pipe having a vertical center line, and means for rotating said pipe about said center line as said suction device moves downward to position the picked up component onto the substrate.
