The new LPKF SmartWeld 6200 can be used integrated as a module within the client’s own production set-up.

Following the successful presentation of the prototype at Lasys 2012
in Stuttgart, LPKF now launches the series version of the
LPKF SmartWeld 6200. This system now makes it possible to create
strong reliable laser welds even when only a small footprint is available
for the equipment. The system can be used integrated within the client’s
own production set-up.

The LPKF SmartWeld 6200 succeeds the tried-and-tested LPKF SmartWeld
6600 (formerly known as LQ-Integration), and requires even less space. It
consists of two components: the control unit only measures 40 x 53 x 60 cm,
respectively 16” x 21” x 24” (w x h x d). This contains the control electronics and
the laser source, all housed within a maintenance-friendly 19” rack system. The
control unit can be positioned outside of the actual working area independent
of the head module which does the welding, e.g. either above or below the
component handling equipment. The control has a field bus interface to
communicate with master computers and transfer the tracking data. 

The head module is permanently connected to the control unit and consists
of a laser scanner and the clamping tool. Thanks to its small footprint of only
330 x 370 millimeters (13” x 15”) it can be positioned within even the most
restricted spaces.

The LPKF SmartWeld 6200 is equipped with a tool that is also designed for
laser protection (laser class 1). The tool holder holds the components to be
welded. The maximum welding contour dimensions are 100 x 100 millimeters
(4” x 4”). The upper drawer is used for the fast, tool-free swapping of the
clamping device. 

The flexible welding unit can be integrated on rotary tables or conveyor belt
systems within fully-automatic production systems. It can also be used
economically and productively in partially automatic production layouts, e.g.
with manually-fed drawers. 

The new laser welding system is equipped with laser sources with outputs
of up to 120 W – the power required depends on the intended components,
the production set-up and the specified cycle times. The glass proprotecting
the optics can be easily cleaned because it is also located in an easily
accessible drawer. The strength of the system is clearly demonstrated by
the welding of small components: “With the LPKF SmartWeld 6200, we are
making laser plastic welding even more flexible. The new system integrates
outstandingly well with existing production lines, and is also particularly
rugged and maintenance-friendly,” explains Frank Brunnecker, Vice President
of LPKF’s Laser Welding Division. He also highlights another exceptional
feature: “Even though the system is so compact, it still contains all of the
functions required for melt travel monitoring; and pyrometer control or burn
detection monitoring systems can also be optionally integrated without any
problems.”Every LPKF laser welding system is supplied complete with highly
efficient software to define the welding contours. LPKF also has its own special
applications center to support clients in developing optimal procedures and
tools for efficient welding processes.
