End Of Line Quality Control Go – No Go: NoiseQC Tests All Noise Emitting Products (End Of Line)
NoiseQC is a system that allows you to do Quality Control of your noise emitting products accurately and efficiently. Through this easy-to-use tool, NoiseQC helps you to decide whether a product is OK or NG based on the sound or vibration it produces.
There are at least two ideas behind NoiseQC.
First, noise and vibration could be used as an indicator for mechanical faults and product defects. Numbers of stories has been heard that customers report a possibility of faults because they hear something not usual on the product they bought. A lot of manufacturers have realized this, and therefore including noise in the quality control process.
Second, a lot of manufacturers of noise emitting products have considered noise as one of their selling point. By developing their product sound quality, manufacturers want the user to have a pleasant perception of their products’ noise. To make sure the products sold to the market satisfy this, then manufacturers need a way to test this.
By implementing NoiseQC, you can overcome both of these problems. Let NoiseQC analyze the sound or vibration of your product, and decide if it’s OK or NG.
Yes, NoiseQC can be configured to measure the noise / vibrations of a unit with 2 engines, either running simultaneously or consequently.
There will be ‘golden egg’ reference spectra for each setting and compared.
NoiseQC has the possibility to create multiple scenario’s for testing. So you could run the NoiseQC test on 1 engine with for example 5 RPM’s. Each setting for the engine has it’s own ‘golden egg’ spectrum and will be measured and compared.
The testing can be started manually or by PLC signal directly from the manufacturing.
Depending on the local situation it can be better to use either noise or vibration measurements to find faulty products coming from your production line.
Sound measurements are good if the background noise around the place where you are performing the sound measurements is low compared with the sound levels that you will measure from your product.
If the background noise is too high, it will influence the measured sound levels and you will get false ‘No Go’ warnings which will slow down the process.
For situations with a relative high background noise level the vibration measurements are recommended, they measure the vibrations of the product with an accelerometer and compare it with a reference spectrum.
It’s a 1 channel vibration accelerator meter.
If your products have any moving / rotating parts, it is very easy to check with noise- or vibration measurements.
You can measure the noise ‘fingerprint’ or vibration ‘fingerprint’ of each product and compare it with a ‘golden sample’ fingerprint. It just takes a few seconds to establish the character of the noise / vibration of the product and compare it with a good product, hence you will directly get a GO or NoGo
NoiseQC end of line quality testing software has a build in option to perform up to 6 different tests on each product (i.e. rpm or load), either manually triggered or by PLC.
- Manual table input
- Detailed results presentation
- Automatic measurement window button
- Bug fixes..
- New User interface
- PLC (or other external controller) Communication
- Multiple testing status (e.g. different RPMs)
