Abstract

This method is useful to load carriers attached to a conveyor that is indexed or continuously moving. The carrier structure is shown in Fig. 1. The addition of the stop on the carrier allows the loading method to load carriers as they index into position in Fig. 2. The carrier pin trips an adjustable air switch which activates the load mechanism so that the part, such as a ceramic substrate, enters the pocket of the carrier as shown in Figs. 2 and 3, respectively.

Carrier and Loader

This method is useful to load carriers attached to a conveyor that is indexed or continuously moving. The carrier structure is shown in Fig. 1. The addition of the stop on the carrier allows the loading method to load carriers as they index into position in Fig. 2. The carrier pin trips an adjustable air switch which activates the load mechanism so that the part, such as a ceramic substrate, enters the pocket of the carrier as shown in Figs. 2 and 3, respectively.

The pocket size is a maximum 0.020" larger than the nominal substrate and
0.010" deeper than the nominal substrate thickness.

The loading scheme includes a latching mechanism, not shown, which locks out a second substrate in each column. A transfer arm swings counterclockwise from a 69 Degrees angle to a 30 Degrees angle. At 30 Degrees the substrates are parallel to and in line with a declining track. Gravity and a fluid assist direct the substrates into the side-guided track and into the carrier pocket. Advantages of the method include: 1) The top surface of the substrate remains untouched; 2) The last piece in each column will load; and, 3) A buffer is not required.
