Abstract

A system and method for surface mount assembly of PCB's, using an automated pick-and-place machine into which component tapes on reels are fed, uses component tape reels each of which has been pre-threaded into its appropriate tape guide and been stored as a reel/tape guide packet in an automated SMD storage tower, from which appropriate packets are retrieved for coupling to the pick-and-place machine.

First claim

The invention claimed is:

1. An automated SMD tower storage unit and pallets, suitable for storing an electronic component tape reel with a pre-threaded tape guide having surface mount components in pockets, the automated storage unit comprising:
an interior surrounded by a wall and a deposition port in the wall, further comprising interior locations that accept automated storage of each of the pallets,
wherein
one or more of the pallets has a horizontal surface with a top and carries an electronic component tape reel with a pre-threaded tape guide that is placed on the top of the pallet with the reel laying on its side, and
the pallets further include a spacer element and/or mechanical holder configured to carry, as a unit, the electronic component tape reel with the pre-threaded tape guide,

an internal robot arm that performs automated pick up and retrieval of the pallets,
the deposition port through which the pallets are passable is where the internal robot arm can pick up the pallets and move them to a selected one of the interior locations inside the automated storage unit storage.

2. The automated storage unit according to claim 1 , further including a barcode reader configured to automatically code link an identity of the electronic component tape reel with an identity of the tape guide into which the reeled component tape is pre-threaded.

3. The automated storage unit according to claim 1 , wherein the tape guides are adapted to automatically peel off a cover film covering the pockets of the component tape as the tape is advanced through the tape guide.

4. The automated storage unit according to claim 1 , wherein the pallet includes a post and the interior locations receive the post.

5. A method of supporting assembly of printed circuit boards by surface mount technology, using a system including an automated pick-and-place machine and an automated SMD tower storage unit, wherein a plurality of tapes with a series of pockets holding electronic components are pre-threaded into tape guides, the method comprising of:
(a) receiving, at a deposition port of the automated SMD tower storage unit, a component tape reel that is pre-threaded into a tape guide,
(b) associating an identity of the tape guide with the component tape reel as a unit prior to storing the unit in the automated SMD tower storage unit,
(c) automatically, by an internal robot arm of the automated SMD tower storage unit, picking up and storing the pre-threaded component tape reel and the tape guide as a unit, with the pre-threaded component tape reel placed on top of a pallet and positioned to have a vertically oriented rotational axis, in the automated SMD tower storage unit,
(d) repeating steps a and b for a plurality of different component tape reels, and
(e) retrieving a plurality of said pre-threaded component tape reel and the tape guide units from storage in the automated SMD tower storage unit for coupling to the pick-and-place machine, using identities associated with the units using.
