An automotive parts manufacturer needed an industrial robot
to perform precise spot welding tasks. RobotWorx helped this customer find the
right robotic solution for their application.
Application Goals:
- Versatility:
The customer produces several automotive parts that need to be spot welded. In
order to save money and floor space, they required a robot that can be
programmed to spot weld four different parts.
- Affordability:
A reconditioned Motoman ES165 robot saved the customer between 40-60% over the
price of a new robot. The reconditioned ES165 performs to the same standards
and even looks brand new.
- Throughput:
The customer required that parts be produced quickly and efficiently. When
combined with the efficiency of a workcell, the ES165 and spot welding gun
produce fast, quality welds in a short time.
RobotWorx Solution:
-
Versatile
Robot: A reconditioned Motoman ES165 spot welding robot with XRC controls
and teach pendant provided the customer the flexability needed to spot welded
numerous parts.
- Custom
Workcell: The custom-built workcell contained two steel tables that are 20" high with 48" X 24" table tops for increased throughput and the ability to load
different parts simultaneously.
- End of
Arm Tooling: A new Obara SRTX-U0662-L Servo transgun package was installed
to precisely spot weld the part. This spot welding package included the mount
bracket to the ES165 wrist and dress out package with chiller.
Spot Weld
Controller: A new Medar WTC 3006 AC Weld Controller powered the end of arm
spot welding gun with a 250 amp 2 pole circuit, 250 VA control transformer, and 1200 amp water cooled SCR. The unit
is designed specifically for the Motoman XRC controller installed on
this robot.- Operator
Station: Controlling and attached to the workcell was an Allen-Bradley SLC
series PLC with PanelView operator station.
- Safety
Package: This workcell included safety fencing for the perimeter of the cell,
one entry door with interlock, robotic zone ring, and two sets of light
curtains for operator protection.
- Service:
All workcells from RobotWorx come with free training at the Marion, Ohio
facility and a one year warranty that covers parts and labor 100%. The customer
also elected to have a RobotWorx engineer come to their facility for additional
training and workcell installation.
The customer chose RobotWorx for their industrial robot
needs because they needed an integrator that could perform everything they
needed, including programming, system runoff, delivery, etc. RobotWorx strives
to meet the needs of every customer.
