Cleaning process

The whole frame is cleaned with high efficiency, but the cleanliness of the workpiece is poor and the inspection pass rate is low

Single piece cleaning, clean workpiece surface and high inspection pass rate

Improve the pass rate and greatly reduce the time for handling nonconforming products

Data acquisition and traceability

It is not convenient for data collection, traceability and analysis

Data can be collected, traced and analyzed in real time

Intelligence has been greatly improved

Parts bump

Manual operation is adopted for circulation between processes

The transfer between processes adopts manipulator to avoid human participation

Effectively reduce bumps

area covered

The equipment is scattered and covers a large area

The equipment is centralized and covers a small area

The production capacity per unit area increased significantly

Administration

There are many staff, difficult management and high management cost

Streamline personnel, reduce management costs and difficulties, and solve the problem of difficult employment.

Improve management efficiency and reduce management cost

quality

There are many human factors, and the workpiece detection accuracy is not easy to control

Not many people participate in the inspection to ensure the stability of inspection quality.

Reduce scrap rate and accelerate brand promotion

When changing models

Replace each single machine tooling

The whole line adopts quick change module. The replacement time is within 1 hour
