3 Product Description
EN-US · 30.30.01.02238 · 01 · 08/22 11 / 34
3Product Description
3.1General Description of the Gripper
The gripping systems use a vacuum to lift defined products. One or more workpieces of different sizes can
be lifted. The gripping system achieves its maximum load-bearing capacity when all of the suction cups
are placed on an airtight workpiece with a smooth surface.
The handling system is responsible for the motion in the various axes (robot/gantry).
The gripper SLG is produced using an additive manufacturing process. It is composed of the gripper head
and the gripper body. The gripper head is preselected by the customer in a configuration module. The
connection flange selected by the customer is integrated in the gripper head (selected flange is listed in
the order confirmation). Based on the customer information, the gripper body is then individually calcu-
lated using the stored algorithm.
Three different versions can be selected for the gripper head:
• Connection to a CobotPump (ECBPi)
• Connection directly to a collaborative robot or a handling system. Depend-
ing on the customer's design, one or two vacuum nozzles are integrated in
the gripper head.
• Connection directly to a collaborative robot or a handling system. The grip-
per head has a direct connection for an external vacuum generator.
The geometry of the gripper body is dependent on:
• The size of the workpiece to be transported
• The variable number of suction points (max. 12)
• The selected suction cups
• The position and orientation of the suction cups (the customer selects the
gripping position on the workpiece, the stored algorithm lines up the suc-
tion cups perpendicular to the workpiece surface)
Each gripper is individual thanks to its customized design. Therefore, the gripper body and the suction
cups are not generally displayed in the following chapters.
3.2SLG-EE (Optional ECBPi)
The gripper is mounted on the ECBPi; the connection to the robot is established via its mechanical inter-
face. The vacuum is supplied to the gripper via the interface between the ECBPi and gripper. The ECBPi is
responsible for vacuum monitoring.

3.5NFC Interface
NFC (Near Field Communication) refers to a standard for wireless data transfer between different devices
over a short distance.
The CobotPump and the vacuum switch VSi function as passive NFC tags that can be read or written by a
reading device such as a smartphone or tablet with NFC activated. Access to the CobotPump / vacuum
switch parameters via NFC also works when the supply voltage is not connected.
There are two options for communicating via NFC:
• Read access only can be obtained via a website viewed in a browser. For
this, no additional app is needed. It requires only that NFC and the Internet
connection are enabled.
• Another option for communication is the "Schmalz ControlRoom" control
and service app. This permits not only read access but also active reconfigu-
ration of the CobotPump's parameters via NFC. The Schmalz ControlRoom
app is available at the Google Play Store.
The reading distance is very short for NFC applications. Determine the position of the NFC an-
tenna in the reading device used. If parameters of the device are modified via NFC, then the
power supply must subsequently remain stable for at least three seconds to prevent data loss
(error E01).
Further information on NFC functionality can be found in the operating instructions for the CobotPump
and vacuum switch (> See ch. Other Applicable Documents).
