【Metal Cutting Process Inspection System】
Purpose and problems：Inspections after cutting process so far all rely on visual checks,
which resulted in a tremendous number of man-hours resulting in an increase in overtime of workers.
In addition, due to differences in workers' abilities, defective items were mixed and received complaints.
Moreover, since it was not possible to prove verification of processing quality and the investigation
also required enormous manpower and time.
Achievement：By combining the image camera with a multi-axis robot and a general-purpose parts feeder, automatic picking and automatic image inspection are possible, thereby reducing the operator. By leaving the image camera image and the inspection record, it was effective in reducing the man-hour for handling customer defects.
【Portable SGM converter】
Purpose and problems：Requirement to produce the inspection unit for automotive air-conditioner control module.
It aimed to be easy to operate with reasonable cost.
Achievement：By applying the electric compact cylinder in the unit, the connector fitting to the product became stable.
【Heater controller function tester 】
Purpose and problems：Cost reduction and maintainability improvement became an indispensable task, thus the inspection machine for a heater controller was required.
Moreover, in order to prevent human error, there was a request to change the manual process to an automated heater operation.
Achievement：We built an inspection system using computers and control boards, thereby achieving cost reduction and improved maintainability. For the heater operation, a robot was used to test the materials such as urethane, and automatic rotation operation was provided.
【Nutrunner FP device】
Purpose and problems：The wheel assembling in the vehicle manufacturing process was entrusted to manpower,
which can cause problems or mistakes in assembling procedure such as forgetting to assemble.
Achievement：The tire assembling procedures differ depending on the type of car and grade, so those were all made into a database. This database guided workers to set up the tools by pressing a button to confirm the work of Nutrunner to avoid an error.
