How Multi-Station Robotic Cleaning Systems Adapt to Different Industrial Parts

Industrial cleaning becomes more complicated when one production line needs to handle different types of components. Parts may vary in size, geometry, material, contamination level and required cleanliness. Using one fixed cleaning sequence for every component can create unnecessary processing time or leave some parts insufficiently cleaned.

A multi-station robotic cleaning system provides a more flexible approach by separating different cleaning operations into coordinated stations. Instead of forcing every component through exactly the same process, the system can be configured around the actual requirements of the parts being produced.

Different Parts Require Different Cleaning Conditions

Machined aluminum components, automotive parts, hydraulic components and other precision metal parts rarely have identical cleaning requirements.

One component may mainly carry machining oil on external surfaces. Another may contain particles inside grooves or holes. Some parts require intensive spraying, while others need controlled air cutting and drying after cleaning.

These differences affect the configuration of the entire cleaning system.

Part characteristic	Configuration consideration
Complex geometry	Robot positioning and fixture accessibility
Heavy oil contamination	Spray intensity and cleaning time
Fine particles	Filtration and rinsing arrangement
Internal holes	Nozzle access and air cutting
Different part sizes	Fixture and workstation capacity
High production volume	Station balance and automated transfer
Strict cleanliness requirements	Controlled process sequence and inspection

For equipment manufacturers, the first step should therefore be defining the parts and their contamination conditions rather than selecting a machine only by its nominal washing capacity.

Why Multi-Station Configuration Matters

A single cleaning station may need to perform spraying, contamination removal, air cutting and drying in sequence. When production demand increases, each operation becomes part of the same process bottleneck.

Separating operations across multiple stations allows the cleaning process to be arranged more logically.

For example, one station can handle initial contamination removal while another performs precision spraying. A following station can provide air cutting or drying before the robot transfers the cleaned component to unloading.

The actual configuration depends on the component and required production output.

For high-volume manufacturing, this structure also allows different workpieces to occupy different stations at the same time. While one component is being cleaned, another can be undergoing drying and a third can be loaded or unloaded.

The result is not simply more cleaning equipment. It is better coordination between individual process stages.

Part Geometry Should Influence Robot and Fixture Design

Robot selection alone does not determine whether an automated cleaning system will work effectively.

The relationship between the robot, fixture and workpiece is equally important.

Fixtures need to hold components securely during spraying and air cutting while leaving sufficient access for cleaning equipment. Poor fixture design can shield contaminated surfaces or create drainage problems after washing.

For parts with different dimensions, the system may require interchangeable fixtures or dedicated positioning structures. The robot program can then select the corresponding process recipe according to the workpiece being processed.

This approach is particularly useful when several component models share one production line.

A suitable fixture should consider:

• Workpiece stability during spraying

• Access to contaminated surfaces

• Drainage of cleaning liquid

• Airflow during drying

• Robot loading and unloading position

• Changeover requirements

• Protection of sensitive component areas

Fixture design should be treated as part of the cleaning process rather than as an independent mechanical component.

Contamination Type Determines the Process Sequence

Oil, grease, chips and fine particles do not behave in the same way during industrial cleaning.

Heavy machining oil may require stronger spray action or a longer cleaning stage. Fine particles may place greater demands on filtration. Components containing residual liquid after washing may require additional air cutting before the final drying stage.

This makes process sequencing important.

A typical multi-station robotic cleaning system may include:

Loading and identification

The robot receives the workpiece from the production line and positions it according to the selected recipe.

Initial cleaning

The first cleaning stage removes the main layer of oil, chips or other contaminants.

Precision cleaning

A separate station can focus on areas where contamination remains after the initial process.

Air cutting

Controlled compressed air removes residual liquid from holes, grooves and exposed surfaces.

Drying

The final drying stage prepares the component for assembly, coating, inspection or packaging.

Not every component needs every stage. Some parts may require only spraying and drying, while others may need several cleaning and rinsing operations.

Production Volume Also Changes the Configuration

A cleaning system designed for small-batch production may not be suitable for continuous manufacturing.

When production volume rises, equipment planning must consider more than the cleaning capacity of individual stations. Robot movement, loading, unloading, drying and waiting time all affect the effective output of the line.

A multi-station arrangement allows these operations to be distributed according to production requirements.

For example, if drying takes longer than the actual washing operation, adding capacity to the drying section may provide greater production improvement than increasing spray capacity.

The same principle applies to loading and unloading. If operators or upstream equipment cannot supply workpieces at the required rate, additional cleaning capacity will not solve the production bottleneck.

For this reason, station balance should be evaluated using the complete production sequence.

PLC Control Connects the Cleaning Stations

Automation becomes useful only when the individual machine functions operate as one coordinated process.

PLC control can manage the sequence between robotic handling, cleaning stations, spraying, air cutting, drying and unloading. Touchscreen control allows operators to select process recipes and monitor equipment status.

For production lines handling multiple part models, different recipes can be assigned according to workpiece requirements.

A recipe may define:

• Cleaning station sequence

• Spray duration

• Air cutting duration

• Drying time

• Robot movement program

• Workpiece position

• Station selection

• Safety conditions

• Alarm parameters

This structure reduces the need for manual adjustments during routine production.

It also provides a more practical basis for process repeatability because the same programmed conditions can be applied to successive batches.

When Should a Custom Configuration Be Considered?

Standard cleaning machines can work well when the workpiece range and production conditions are relatively stable. Custom configuration becomes more relevant when the production environment involves several variables.

Typical situations include:

• Multiple workpiece models on one line

• Significant differences in component dimensions

• Different contamination levels

• Strict cleanliness requirements

• Limited operator intervention

• High-volume production

• Integration with upstream or downstream equipment

• Different cleaning sequences for different products

In these cases, the cleaning system should be designed around the complete production process rather than selected as an isolated machine.

A robotic cleaning equipment manufacturer needs to evaluate the workpiece, fixture, robot reach, station arrangement, cleaning method, drying requirements and production takt together.

Application Testing Should Come Before Final Configuration

Theoretical equipment selection cannot replace practical cleaning trials.

Before finalizing a multi-station robotic cleaning system, representative workpieces should be tested under the proposed cleaning conditions. The test should examine whether contamination can be removed, whether liquid can be discharged effectively and whether the final drying result meets production requirements.

Testing can also identify problems that may not be visible during initial equipment planning.

For example, a component may appear easy to clean from the outside but retain oil inside a blind hole. Another part may require a different fixture angle because a structural feature blocks spray access.

These findings can be used to adjust nozzle arrangement, robot programming, station sequence and fixture design before the complete production system is manufactured.

Multi-Station Systems Support Production Flexibility

Production requirements can change after equipment installation. New component models may be introduced, output targets may increase or a different cleaning standard may be required.

A configurable system provides greater flexibility for these changes.

Additional fixtures, process recipes or station functions can sometimes be incorporated without completely replacing the existing cleaning equipment. The exact scope depends on the original machine architecture and available capacity.

This flexibility can be important for manufacturers supplying several customers or producing multiple product families on the same production floor.

Choosing the Right Automation Structure

The right automated parts cleaning system is not necessarily the one with the largest number of stations.

Too few stations can create bottlenecks, while excessive station capacity can increase equipment cost and occupy unnecessary production space.

The better approach is to match the configuration to actual manufacturing conditions.

Key questions include:

• How many part models will be processed?

• What contaminants need to be removed?

• Which surfaces require direct cleaning access?

• How many components must be processed per hour?

• Which process stage has the longest duration?

• How often will fixtures or recipes change?

• What level of cleanliness is required after cleaning?

• How will the cleaning machine connect with the production line?

Answers to these questions provide a more reliable basis for equipment configuration.

Building a Cleaning System Around the Production Process

Industrial cleaning automation is most effective when the cleaning machine is treated as part of the manufacturing line rather than as a standalone washing unit.

For different industrial parts, the combination of robotic handling, fixtures, cleaning stations, air cutting, drying and PLC control can be adjusted according to actual production requirements.

KLL's robotic cleaning machine supports customized workstation configurations and can use KUKA or FANUC robots for automated workpiece handling. Fixed-point spraying, air cutting and drying can be coordinated through PLC and touchscreen control, with the cleaning process configured according to different components and particle-size requirements.

For manufacturers considering an automated parts cleaning system, the key question is not simply how powerful the machine can be. The more important consideration is whether the complete process can provide stable cleaning performance while fitting the required production rhythm.

That is where multi-station robotic cleaning systems can provide practical value for modern industrial production.
