Definitions

  • the invention relates to a magazine with receptacles for exchangeable pipettes of a placement head for equipping substrates with electrical components, the receptacles being arranged in at least one row parallel to the substrate plane, the magazine having at least one interacting with the pipettes in the row direction of the recordings has adjustable slider.
  • Such a magazine is e.g. made known by EP 0933985 A. After that, the magazine between one is that
  • Placement area receiving substrate and a pick-up area where the components are picked up from a placement head with several pipettes and transported to the substrate, the components being held on the pipettes by means of vacuum.
  • Different component types require different pipettes, which, if necessary during operation, as well as dirty or defective pipettes, must be replaced by other pipettes from the magazine.
  • the slide with its locking segments engages behind the pipettes on the side shoulders in a locking position.
  • the slide is moved to a change position in which the locking segments have been removed from the overlap area and release the pipettes.
  • the receptacles for the pipettes remain largely open at the top, so that when the components are transported from the pick-up area to the placement area, the pipettes can be contaminated by dust or falling components, which can affect the suction Reduce cross-section and can cause an inaccurate and uncertain hold of the pipette on the placement head
  • the invention has for its object to prevent contamination of the pipettes stored in the magazine.
  • the cover segments are designed in such a way that they cover only the endangered areas of the pipettes and not the entire pipette magazine. Such a complete cover would require a very large slide stroke, which requires a large drive effort and a large lateral clearance.
  • the cover segments can be kept so narrow that they only cover the endangered areas of the pipettes and keep them free of foreign bodies. This makes it possible to move the cover segments by half a pitch, for example, with a short slide stroke so that the receptacles are completely released and the pipettes can be changed without hindrance.
  • a short slide • stroke can be carried out in a simple manner, for example by means of a compressed air cylinder.
  • Such a covering device can also be used in magazines in which the pipettes are not fixed by a bolt slide but by other retention means, for example in the manner of a bayonet catch.
  • the distance between the receptacles in the magazine must be kept so large that the cover segments find space in the space between the receptacles so as not to disturb the pipette change.
  • the space between the receptacles is kept correspondingly small.
  • the development according to claim 2 covers the entire assembly area of the pipette.
  • the cover plate according to claim 3 can be made very thin without high processing costs. Its top remains at a sufficient distance below the transport level of the components.
  • the locking elements according to claim 4 are used to fix pipettes locked on the placement head after insertion into the receptacles and to hold them back securely in the receptacles when the pipette holder is raised.
  • the locking position corresponds to an intermediate position of the slide between the storage position and the change position, the cover segments being shifted just so far that the area covered by the holder is released.
  • the slide is then moved into its storage position, in which the covering segments completely cover the central area of the pipettes.
  • Such a magazine can perform both the covering function and the locking function with little additional effort.

The slide 4 is moved into the change position shown in FIG. 6. The holder 12 with the pipette 1 fixed thereon is then lowered so far that it is placed in the receptacle 3. The slide is then pushed back into the locking position shown in FIG. 5. The holder 12 is now pulled up, the pipette 1 being retained in the receptacle 3 by the locking elements 6 and being withdrawn from the holder 12. Thereupon the latter moves to another pipette 1 stored in the magazine and the slide 4 is again moved into the change position shown in FIG.

Abstract

Selon l'invention, un élément coulissant (4) d'un magasin comportant des logements pour des pipettes (1) servant à la mise en place de composants électriques sur des substrats est pourvu, au-dessus des pipettes (1), de minces segments de recouvrement (9) qui recouvrent des ouvertures supérieures des pipettes (1) lorsque l'élément coulissant (4) se trouve dans une position de stockage de pipettes. Lorsque ce dernier (4) se trouve dans une position de changement de pipettes, les segments de recouvrement (9) sont déplacés de sorte qu'ils dégagent complètement les logements (3). On obtient ainsi, avec un mécanisme de coulissement peu complexe, un recouvrement fiable des zones des pipettes (1) sensibles aux impuretés.
