Project Overview

This case is an automatic EU tote cleaning system implemented at an electronics manufacturing company. Designed specifically for EU totes destined for the Japanese market, the equipment completes exterior cleaning, dust removal, and static elimination for a single EU tote in just 50 seconds. It supports customized cleaning for totes of various sizes and has been maturely adopted by Japanese electronics manufacturers, effectively solving persistent challenges such as incomplete manual cleaning, residual static, and low efficiency.

Challenges Faced by the Customer

Before project initiation, the customer faced the following core issues in their EU tote circulation process:

• Incomplete cleaning with residual dust and particles: EU totes accumulate dust and contaminants during circulation. Manual cleaning with rags or air guns fails to thoroughly remove debris from gaps and corners, affecting the cleanliness of precision components inside the totes.

• Ineffective static elimination: Plastic EU totes generate static electricity during handling, which attracts dust and may cause electrostatic discharge damage to sensitive electronic components. Manual cleaning cannot effectively eliminate static.

• Low efficiency and high labor consumption: Manual cleaning takes several minutes per tote, and quality depends on worker skill and diligence. As production scales up, cleaning consumes significant labor at high cost.

Solution and Core Features

We provided the customer with a fully automatic EU tote cleaning system, featuring the following core capabilities:

• Efficient cleaning: Multiple rotating brushes combined with high-pressure air blow thoroughly clean all six surfaces of an EU tote in 50 seconds, removing attached dust and particulates.

• Dust removal and static elimination: Built-in high-efficiency filtration and ionizing air bars eliminate static during cleaning, preventing re-adhesion of dust and protecting precision components from static damage.

• Multi-size compatibility: The system supports various EU tote sizes via a quick-adjustment mechanism, enabling fast changeover without tooling replacement to accommodate diverse tote types.

• Automated operation: Conveyor-based auto-loading/unloading and fully automated cleaning require minimal operator intervention—staff only need to periodically replenish and retrieve totes.

• Stable and reliable: Proven components and control systems ensure consistent cleaning quality and stable operation, meeting continuous production takt requirements.

※ Customized sizes are available to meet more tote cleaning requirements.

Project Results

After implementation, the customer achieved the following improvements in tote cleaning operations:

• Cleaning efficiency significantly improved: Cycle time reduced from several minutes to 50 seconds per tote—over 5x faster—meeting high-frequency production line demands.

• Cleaning quality markedly enhanced: Mechanical cleaning combined with dust removal and static elimination far surpasses manual methods, effectively eliminating residual dust and static adhesion while protecting component quality.

• Labor costs greatly reduced: Automated cleaning replaces dedicated manual labor, freeing up workforce and reducing labor costs by over 70%.

• Consistent cleaning quality: Stable equipment performance eliminates dependency on operator skill, delivering significantly improved and consistent cleaning results.
