KOYO ELECTRONICS INDUSTRIES has been consistently involved in the development, manufacturing, and sales of electronic equipment since its establishment in 1955, continuing to create products that surpass reliability and functionality standards. In the production of products that require strict quality, such as the main product of in-vehicle electronic devices, PLCs acting as the control tower for machine control, and rotary encoders, the challenge has become how to increase productivity according to increase in demand.
A member of the JTEKT group who boasts the world’s top share in the automotive steering bearings, has installed a UR3 cobot from Universal Robots (UR) to improve productivity. For in-vehicle products that require strict quality standards, quality has improved while productivity has increased 31% due to the operational stability of the cobot.
The business transformation
The first thing the company worked on was a review of the panel computer inspection process. In the pre-process, operators perform product assembly and visual inspection, and in the post-process the operators apply styluses to the touch panels to confirm the devices react as intended. Mr. Katsuhiko Nakatani, Deputy General Manager of the Production Department, explains; “Traditionally, three people were performing the series of work. As there were some bottle neck processes, we reallocated some of them which resulted in the balance between the pre-process and the post-process being lost. So, we examined the implementation of a UR cobot to improve the productivity of the post-process.”
