Abstract

A carrier tape suitable for facilitating in-line washing of components for use in pick-and-place operations. The components are loaded into their respective pockets after emerging from one or more forming machines, with the components having lubricant remaining thereon, and are placed into respective pockets of the carrier tape with lubricant remaining on the components. The carrier tape has a plurality of pockets for receiving respective components, with the pockets having washing openings through which cleaning fluid is imparted to the components and allowed to drain from the pockets as the pockets are passed through washing and drying stations. After being washed and dried, a cover strip is detachably adhered to the carrier tape to maintain the components in their respective pockets.

Claims

1. A method for producing a carrier strip having cleaned components disposed therein, the method comprising:

forming said components in one or more forming machines, at least one of which forming machines utilizes machining lubricant;

providing a strip portion of a carrier strip having a top surface, a bottom surface, a plurality of pockets formed in the strip portion and spaced along the strip portion for receiving and carrying respective ones of said components, with said plurality of pockets each having an upper removal opening through the upper surface to allow removal of the components from their respective pockets through said upper openings for automated pick-and-place operations, and said plurality of pockets each having a washing opening through the bottom surface;

inserting the formed components, having machining lubricant thereon from the forming machines, into respective pockets of the strip portion; and

washing at least a substantial portion of the machining lubricant from the components while the components are maintained within their respective pockets, through the washing opening in the strip portion.

2. A method in accordance with claim 1 in which the components are maintained in their respective pockets during said washing by an element which overlaps the upper openings of a plurality of said pockets.

3. The method of claim 1 further including engaging a removable cover strip to the top side of the carrier strip to maintain the components in their respective pockets.

4. The method of claim 1 further including drying the components while the components are maintained within their respective pockets.

5. An apparatus for use with one or more forming machines, at least one of which utilizes machining lubricant, for producing a sealed carrier strip having cleaned components therein, the apparatus comprising:

a carrier strip advancement device for advancing a strip portion of the carrier strip, having a top surface, a bottom surface, a plurality of aligned pockets formed in the strip portion and spaced along the strip portion for receiving and carrying respective ones of said components, with each of said plurality of pockets having an upper opening through the top surface which upper opening is larger than the component received in the respective pocket to allow removal of the components from their respective pockets through said upper openings for automated pick-and-place operations, and said plurality of pockets each having a washing opening through the bottom surface;

a component loading device for loading the components output from said one or more forming machines into respective pockets of the strip portion, with the components having said machining lubricant remaining thereon; and

a washing device for washing the components through the washing openings in the bottom of their respective pockets to remove at least a substantial portion of the machining lubricant from the components while the components remain in their respective pockets.
