7.1.3.5 Description of the functions

The magazine for standard nozzles has 1 positioning fiducial for position detection, while the mag-

azine for special nozzles/grippers has two. The nozzles are fixed by balls in the holder. They are

then either clamped or released for removal, depending on the direction of rotation of the DP axis.

7.1.3.6 Component reject bin

A component reject bin may be installed for the SIPLACE TwinHead. This is positioned beside the

fine-pitch vision module (see Fig. 7.1 - 12

, page 286).

7.1.4 Grippers and special nozzles

The SIPLACE placement machines can process components based on through hole technology

and odd-shaped (OSC) components, in addition to the standard SMT spectrum. SIEMENS L&A

also continuously develops special nozzles and grippers in parallel.

Special nozzles are available for all placement heads in order to process placement jobs with max-

imum speed, precision and flexibility. The use of automatic nozzle changers also reduces the set-

up times that occur at a product change.

SIEMENS L&A can provide mechanical grippers for Pick&Place heads. If a component's surface

is not suitable for sucking up with nozzles, then it can be picked up and placed with mechanical

grippers. There are two types of gripper, and their functions can be divided into two groups:

– Grippers that grip the component at its outer edges and

– Grippers that grip the component at its inner edge.

Information on special nozzles and grippers is available from SIEMENS L&A. For the production

of special magazines and grippers, again contact SIEMENS L&A.
