- Advanced Robots for Arc Welding, Spot Welding and Materials Handling -

New ProductAug 29, 2013

 Yaskawa Electric Corporation (Junji Tsuda, Representative Director, Chairman and President) is a pioneer in developing top-of-the-line industrial robots that optimally fulfill a variety of uses. Yaskawa has recently developed new arc welding, spot welding and materials handling robots as well as a new type of robot controller. Poised to create even more added value by fulfilling global needs region-by-region, this new lineup will go on sale across the world beginning September 2.


1. Goals of Product Launch

 Recently efficiency, the environment and quality have been key themes in automobile development. The manufacturing process for the bodies of these cars has seen the creation of efficient, low-cost, energy-efficient assembly lines. Above all, shortening of the assembly line and lessening of the number of processes -both with the aim of minimizing costs -as well as the creation of assembly lines to match production patterns in developing countries are absolutely critical. To satisfy these needs, Yaskawa’s new arc welding and spot welding robots are ultra-fast and high-precision, as well as small and slim, which make high-density installation of robots possible, while stressing reliability, serviceability and safety.
 What’s more, while the automobile and electro-mechanical industries still represent the bulk of industrial robot users, the bedrock of usage of industrial robots is an ever-expanding one, with the focus of current expansion being the food product, pharmaceutical and cosmetics industries. Responding to the demands of these new markets, the recently launched materials handling robot offers solutions to help improve the productivity of automated production facilities in the assembly and delivery areas.

2. Main Features

(1) MOTOMAN – MA1440 Arc Welding Robot
 With a new type of arm, this space-saving arc-welding robot is ultra-fast and can handle higher payloads.


1. Possible to optimally outfit*1 for the welding process
 Able to handle twice the payload of previous models (previous model: 3 kg → new model: 6 kg), it is possible to install on the MA1440 a variety of sensors and servo torches that had until now been reserved for use with larger models. Moreover, it is possible to select the optimal outfitting for the shape of work objects and equipment layout with the internal/external torch cable support of a single robot.


2. Reduced robot moving time thanks to high-speed operations
 The MOTOMAN – MA1440 features improved axis speed*2 (previous model: 2070°/s → new model: 2150°/s). Especially noteworthy is the accelerated air cutting*3 feature, which leads to truncated cycle time when used on jobs involving longer movements to weld positions and numerous approaches, thus helping to realize remarkable improvements in productivity.


3. New aerodynamic shape leads to improved ease of use
 With its aerodynamic arm, the area of interference with work objects and jigs is reduced and the robots can be stationed in closer proximity to them, making it possible for welding to take place at positions on the backside of the work object that had been hereto impossible to reach. What’s more, the inner diameter of the wrist axis has been enlarged (previous model: φ42 mm → new model: φ50mm), and the number of stored cables can be increased.


4. Improved arc welding functionality with the new DX200 controller
 Arc welding functionality has been vastly improved thanks to the Welding Conditions Guide function as well as the Real Time Arc Monitor function, which both simplify the establishment of optimal welding current / welding voltage.


*1 Outfitting: the installation on the robot body of devices and sensors necessary for welding and similar activities
*2 Axis speed: the speed at which all six of the robot’s axis move
*3 Air cutting: the movement of the robot’s welding torch from the welding position to the next welding position or to the standby position.


(2) MOTOMAN – MS 210, MS 165 Spot Welding Robot
 This spot welding robot knows no peer when it comes to an ultra-fast, high-density installation.


1. Ultra fast operations made possible thanks to a new vibration control feature
 Axis speed has been increased by up to 25% thanks to the adoption of lightweight components and increased rigidity of the drive mechanism, as well as the innovative vibration control feature of a new type of controller. This increase has led to a 30% decrease in cycle time over previous models. Used in conjunction with a recently developed sensor-free learning control feature, a further reduction of 10% is possible.


2. Small and slim shape makes a high-density installation possible
 With the adoption of a gas balancer*4 and slim arm, the width of this robot has been reduced by 25%. What’s more, the base has also undergone miniaturization, leading to a footprint reduction by 43%. Meanwhile, a high-density installation has fed further improvements in productivity.


3. Improved payload and less wire and cable
 This model has a payload of 210 kg when outfitted with a spot gun, making it possible to use with a large spot gun. Also, maintenance characteristics have been enhanced with modularization of the outfit cable creating less of a power cable presence (previous model: 2 cables → new model: 1 cable).


4.Improved spot welding functionality made possible thanks to a new type of controller
 In addition to being outfitted with a motor gun automatic tuning feature for optimally controlling motor guns with differing specifications, simplified functions for teaching and motor gun setup has also been enhanced.


*4 Gas balancer: A cylinder used to reduce motor load when the arm is going up or down or is in standby position. It accomplishes this by balancing the weight of the robot’s arm with compressed gas applied in the opposite direction. The gas balancer is more compact than the conventional spring-loaded type of unit and uses a highly balanced N2 gas load.


(3) MOTOMAN - MH 12 Materials Handling Robot
 An ultra-fast and compact materials handling robot with 12 kg payload


1. Fastest in class with payload of 12kg
 With vastly improved payload (previous model: 6 kg → new model: 12 kg), the MH 12 is the fastest in class.


2. Improved productivity made possible due to improved speed and a larger work area
 With decreased interference with the material being handled thanks to an aerodynamic interference-free arm and an expanded work area, the MH 12 is a major contributor to improved productivity.


3. Improved device integration with a slim body
 Construction that features an outfit cable and accessories for use when handling materials able to be compactly stowed away/loaded helps to make it possible to make built-in devices compact, meaning that it doesn’t take up much space to install.


(4) New DX 200 Controller
 A robot controller optimally designed to answer the needs of the global user


1. Enhanced security functions
 Tool conversion surveillance functions, velocity limit functions and other software-based security functions as well as velocity range restriction functions that can be toggled during operations according to the robot operation requirements, the size of work objects and the distance of the robot from the operator, have been enhanced.


2. A space-saving cabinet design
 The external axis control (three axis) and options such as functional security – which have traditionally been stored in an additional locker – could be put in a compact standard cabinet. It is possible to add a stack cabinet loaded with a second robot control and customized electronics on the standard cabinet. Thus, the area for installing the controller has been reduced.


3. Improved maintenance characteristics accompany reduced wiring within the controller
 The interior of the controller has been designed to optimize configuration and reduce the amount of wiring present. Even after the installation of optional equipment, the controller’s appearance remains unblemished, and renders maintenance work such as swapping out the unit a snap.
