Hydrochloric Acid Cleaning of Steel Plates using Doosan M1013

Industry > Metal·PlasticsApplication > Machine TendingApplication > Loading·UnloadingSector > Manufacturing

This cleaning automation solution utilizes the Doosan M1013 collaborative robot to automate the process of cleaning steel plate samples with hydrochloric acid. It is highly effective in increasing operational safety.

Hydrochloric acid cleaning is a task frequently avoided by workers as it involves handling hazardous substances.

Additionally, significant preparation time was previously required for workers to put on protective gear before each task. Through robot automation, the cleaning process can now be performed independently, allowing workers to focus on downstream processes and improve overall work efficiency.

Components

Robot	Robot: Doosan Cobot M1013 6-axis articulated collaborative robot, 6 torque sensors, payload 10kg, repeatability ±0.05mm, reach 1,300mm, weight 33kg.

Workflow

STEP 1.	Loading: Workpieces are fed into the system.
STEP 2.	Acid Bath: The robot picks the workpiece and submerges it in the hydrochloric acid solution.
STEP 3.	Rinsing: After a set period, the workpiece is washed with water.
STEP 4.	Unloading: The workpiece is discharged onto the output conveyor.

Features

Work Environment Improvement for High-Avoidance Tasks

Hazard Elimination: Removes the need for human workers to handle dangerous substances (hydrochloric acid solution).

Improved Work Efficiency

Reduced Prep Time: Automating the acid cleaning process eliminates manual preparation and waiting times.

Parallel Processing: Enables downstream tasks to be performed in parallel, reducing the total processing time.

Compact Installation & Enhanced Durability

Space Optimization: Utilizes compact collaborative robots to minimize the floor space required for installation.

Protective Engineering: A pressurized protective cover is applied to ensure robot durability against potential infiltration by hydrochloric acid.

Results

ROI Period	18 months
Key Benefits	Enhanced workplace safety and increased job satisfaction by eliminating high-avoidance tasks.
Client Feedback	Since the process involves hydrochloric acid, workers were reluctant to perform the task. Automating it has not only increased worker satisfaction but also shortened processing times, significantly boosting overall efficiency.
