Method for preventing assembly mixing during manufacturing

Disclosed is a method for preventing assembly mixing during manufacturing. Benefits include an improved manufacturing environment.

Background

      A limited number of tray colors are available conventionally. The additional cost of changing the color of a whole tray can be as much as 50%. The conventional marking method is not consistent and not flexible. The marking and/or identification block may not be very visible from a distance of more than about 10 to 15 inches.

              Manufacturing and OEM assembly operations may not be able to identify a tray and the components or assemblies in them from more that about 15 inches away for inspecting sorted stacks for consistency prior to shipment or assembly use.

      Conventional technologies utilize an ID block with an alphanumeric code or a combination of the ID block and a hand-painted stripe (see Figure 1). The tray number is indistinguishable. The stripe is poorly and inconsistently applied.

General description

      The disclosed method enables the distinctive marking of injection-molded trays to aid in visual identification during factory operations for kitting, sorting, and preventing assembly/component mixing.

      This marking design and methodology enables easy conversion of existing molds and easy implementation for all new thick matrix tray molds for injected molded JEDEC style trays.

      The disclosed marking system enables easy recognition from 3 to 5 feet.

              The key elements of the method include:

•             Moldable tool that incorporates the marking technology into the tray

•             Staggered identifier within the insert boundary

•             IPN and ID element design size

Advantages

              The disclosed method provides advantages, including:

•             Improved manufactur...
