Process Overview

This solution is a manufacturing automation system that automates the insertion process of automotive weather strip clips using a cartesian robot.

By automating the entire continuous workflow in-line, including raw material cutting, clip insertion, and appearance inspection, productivity has been significantly improved.

Components

Robot

Cartesian robot

Peripherals
  • Sony machine vision system (ez-VISION)

  • Pattern matching: Detects presence and condition of measured parts

  • Edge: Checks part presence and assembly condition

  • Length: Detects position and appearance defects, measures distance

  • Histogram: Inspects contamination and print density

  • 1D/2D barcode: Manages product lot manufacturing information

  • OCR: Recognizes characters such as model name and expiration date

  • Circle: Measures location and size of circular parts

  • Color pattern matching: Color matching and comparison

  • Edge contour: Surface inspection and defect inspection

  • Blob: Measures area

  • Raw material infeed feeder

  • Cutting unit and hole machining unit

  • Product transfer conveyor

  • Product fixing jig

Workflow

STEP 1.Strip alignment and cutting
STEP 2.Hole machining and clip insertion
STEP 3.Vision inspection for hole machining and clip insertion
STEP 4.OK/NG sorting and discharge
STEP 5.Washing
STEP 6.Appearance inspection
STEP 7.Finished product discharge

Mobile Case Transfer System for Conveyor-Line Warehouse Automation

Mobile Case Transfer System for Conveyor-Line Warehouse Automation

Process Overview This solution uses a stacker that travels along a line and automatically transfers boxes using a conveyor system. By transferring boxes to a higher position with a stacker, it enables faster box handling compared to conventional methods, improving productivity. It also reduces the risk of safety accidents by separating operators from the work area. In addition, the stacker's travel section is configured with PLC control, making maintenance convenient.

Deburring Robot Automation: Burr Removal on Ibarri Parts — Seriously This Easy?! 😮

A robotic deburring system that automatically removes burrs (BURR) generated on the machined surfaces of nickel parts applied to Honda Accord vehicles using two robots. Collaboration between a positioning robot and a deburring robot. For areas where the deburring tool cannot access, a dedicated deburring device is configured to fully perform deburring on complex-shaped machined surfaces. Integrated with the machining line to implement full-process automation, including deburring, washing, inspection, rust prevention, and packaging.
