How does FFU above optical inspection equipment take into account particle control and vibration requirements?
Why is optical detection sensitive to vibration?
Optical inspection equipment is often used to detect small defects, dimensional deviations or appearance abnormalities on product surfaces. This type of equipment is relatively sensitive to vibration. Vibrations can come from the ground, the movement of the equipment itself, the operation of peripheral equipment, or FFUs installed above the equipment.
If FFU fan vibration is transmitted to optical inspection equipment, it may affect measurement accuracy, image stability, or inspection repeatability. Even if the vibration amplitude is small, it may have an impact on high-precision detection.
Therefore, when optical detection equipment is equipped with FFU, particle control and vibration requirements need to be considered at the same time. Don’t just focus on clean air supply and ignore vibration transmission. Aili Industry has complete production capabilities in FFU complete machines and equipment matching, and can provide vibration reduction configuration solutions based on equipment conditions. For the basic structure of the FFU machine, you can refer toAili Industrial FFU fan filter unit。
Through what paths are vibrations transmitted?
Vibration transfer usually takes several paths. Structural transmission, the FFU is connected to the equipment through a bracket or mounting structure, and the vibration is transmitted along the structure. Air transfer, fan noise and airflow pulsations travel through the air. Pipe transmission, if the FFU is connected to the air duct, the vibration may be transmitted along the air duct.
Understanding the transmission path helps to select appropriate vibration damping measures. If the FFU is mounted directly on the device frame, the fabric pass may be the primary path. If the FFU is installed on a suspended ceiling, vibration may be transmitted through the suspended ceiling structure.
What are the vibration reduction measures?
Vibration reduction measures can be considered from several directions. Install vibration pads or dampers to reduce vibration transfer from the FFU to the mounting structure. Use flexible connections to reduce vibration transmission along pipes or structures. Adjust the FFU installation position to avoid installing it directly above or to the side of sensitive equipment. Choose a low-vibration fan to reduce the source of vibration.
Vibration reduction measures should be selected based on equipment vibration requirements and FFU installation conditions. If the equipment has high vibration requirements, a combination of measures can be used.
How to choose fans and installation methods
Fan selection affects vibration levels. The vibration characteristics of fans of different types and different speeds may be different. The vibration data and operating speed of the fan can be confirmed when selecting the model.
Mounting method affects vibration transmission. If the FFU is mounted directly on the equipment via a rigid bracket, vibration may be transmitted directly. Vibration transmission may be reduced if vibration-damping brackets or elastic mountings are used.
For device-side matching, you can refer toEquipment end fan filter unit andCustomize the EFU equipment-side fan filter unit to understand the equipment supporting solutions.
How to do working condition test
The impact of vibration needs to be tested under actual operating conditions of the equipment. The test content includes: equipment vibration level when FFU is running; equipment vibration changes at different FFU speeds; whether equipment detection accuracy or repeatability is affected; vibration superposition when peripheral equipment is running.
Tests can be conducted before and after installation of vibration reduction measures to compare the effects. If vibration still affects the equipment, the vibration reduction scheme or FFU operating parameters can be further adjusted.
How to ensure particle control
Vibration reduction measures should not affect particle control. The air supply coverage and cleanliness of FFU still need to meet the requirements. If the vibration reduction installation changes the FFU position or air supply direction, the air supply coverage needs to be re-confirmed.
Particle control and vibration control can be considered simultaneously. For example, adjust the installation method without affecting the air supply, or choose a low-vibration fan while maintaining air volume.
Issues that should be confirmed in advance during project communication
In the FFU project stage for supporting optical inspection equipment, it is recommended to confirm the following with the FFU manufacturer and equipment party: equipment vibration requirements; FFU installation location and method; vibration transmission path; vibration reduction measures; fan vibration data; equipment operating status test; particle control requirements; detection accuracy verification; adjustment and optimization plans.

in conclusion
When optical inspection equipment is equipped with FFU, clean air flow and vibration transmission should be considered at the same time. Just because the fan operates normally in a stand-alone state, it does not mean that it will not affect precision measurement after being installed on the testing equipment. Vibration transmission paths, vibration reduction measures, fan selection and operating condition testing are the main considerations. Particle control still needs to be ensured.
