Abstract

Many electronic products currently on the market require software to be programmed into the microprocessor on board in order to function. In addition many of these same products undergo extensive functional testing during the manufacturing cycle. Current testing and programming operations in the production of electronic products require tremendous amounts of time and manpower to move products from programming stations to testing stations. Additional time and manpower is also required to connect appropriate fixturing to the product to enable the test/programming operation to take place. Opportunity also exists in manual movement environments for material to become "lost" or mishandled particularly when dealing with high volumes.

A SOLUTION FOR NON-ROBOTIC MATERIAl+ HANDLING

IN AUTOMATED TEST ~

  Many electronic products currently on the market require software to be programmed into the microprocessor on board in order to function. In addition many of these same products undergo extensive functional testing during the manufacturing cycle. Current testing and programming operations in the production of electronic products require tremendous amounts of time and manpower to move products from programming stations to testing stations. Additional time and manpower is also required to connect appropriate fixturing to the product to enable the test/programming operation to take place. Opportunity also exists in manual movement environments for material to become "lost" or mishandled particularly when dealing with high volumes.

  The process of eliminating these problems of handling and fixturing are addressed by the use of a conveyorized in-line test and programming operation. The primary physical elements of the new process are the serial location above the conveyor of the test/programming boxes, the construction of the test boxes themselves, and a pallet which serves multiple functions. Operationally, the combination of the programming and the testing operations into a single test/programming operation are of primary importance to the overall process along with a pallet which carries the product to supplant what amounts to as the underside of the test box. This comes about by virtue of the line layout and the need to position these test boxes above the conveyor (see figure 1).

  The automated handling and testing is accomplished without the use of robotic manipulators thereby eliminating a level of complexity and cost found on other automated test applications. The process works in the following manner. As palletized products are received into the test queue area, determination is made at the conveyor controller level as to whether or not there is an available test box. If there is no test box available the product remains in

queue. Once a test box bkcomes available the product is released from queue anh allowed to move down the conveyor to the chosen:available test box. Upon arrival at the test box the palletized product is stopped (see figure 2) and lifte...
