Automating Pressurization Process With Small Robots OVR

Issue: Automate manual tasks of feeding, pressurizing, inspecting, and discharging of workpieces to the pressurizing equipment were all carried out by a worker in exclusively

Challenge:

The stator core, one of the motor parts, consists of several steel plates stacked on top of each other. Gaps between the steel plates can cause uneven paintwork, therefore it must be re-pressurized after pressing to fill in the gaps. Feeding, pressurizing, inspecting, and discharging of workpieces to the pressurizing equipment were all carried out by a exclusively worker in exclusively.

Solution: Workpieces Feeding and Discharging Processes in a Single Equipment

  • Consider automating the pressurization process for labor saving
  • Automating workpieces feeding and discharging using the robot controller MRC01 and 4-axis articulated robot
    Place the workpiece on the conveyor, and feeding and discharging of the workpiece to pressurizer with robot
  • The workpiece is automatically inspected after pressurization, and the workpiece that are judged to be OK are aligned in a bucket by another robot
  • The automatic bucket exchange equipment allows for long periods of continuous operation

Key Points for the Adoption

MRC01 Robot Controller Operability and Versatility

MRC01 Robot Controller Operability and Versatility

In terms of "control," the robot controller MRC01, which allows for easy programming, is used. Experience using the MRC01 in a different process, and the deciding factor was that it could be quickly start up the equipment with the same feeling of operation.
In addition, once the MRC01 is mastered, any type of Small Robots OVR can be operated using the same procedure. In order to continue automating equipment in the future, another benefit was highly versatility that the allowing to use a variety types of robots without having to spend time learning and training how to operate it


Maintainability After Robots Installation

Maintainability After Robots Installation: Costs Comparison

"Maintainability" was another key point. Since stators are parts used in many products, the production line cannot be stopped. When a typical industrial robot breaks down, it is necessary to contact the manufacturer or a specialist maintenance company. For this reason, it typically takes several days to be restored, but the Small Robots OVR can be replaced some of its motors and parts in-house. Maintenance costs can also be reduced because maintenance contract fees are not required, leading to total cost reduction.

*Oriental motor also replace the motors during maintenance and servicing. Please contact your nearest Oriental Motor branch or sales office.



Introduction Effect

Reduce the Number of Workers From 1 to 0

Before OVR and After Effect

Attachment and detachment work is frequent because the pressurization time was short, one person in exclusively was required to be worked at all times.


Implementation of the equipment has made it possible to operate the machine unattended for long periods of time, and the person responsible for other machines could set up the workpieces in the spare time, eliminating the need for designated worker.


 

Time Reduction From the Robot Failure to Restoration

Time Reduction From the Robot Failure to Restoration

The Small Robots OVR can time reduction from the robot failure to restoration, because it can be replaced some of its motors and parts in-house. In actually, the tip of the arm was accidentally damaged when setting up the equipment, but the parts were quickly obtained and the equipment can be restored the next day.

*Oriental motor also replace the motors during maintenance and servicing. Please contact us for service and support.
