3D glass profile measurement

 

The ultimate solution for 3D glass curved surface measurement, with a large measurement angle of ±61°, non-contact and fast measurement, without complex rotational motion, can span the entire 3D glass section.

THINKFOCUS "3D Glass Profile Measurement Spectral Confocal Sensor S3D-1100" has the characteristics of large measurement arc angle, large measurement height range, fast detection speed, high real-time performance, and fast secondary development and import. With THINKFOCUS' "3DMeasure" measurement software and "programmable encoder frequency division module", users can carry out secondary development efficiently and quickly.

Requires the customer to have the following conditions:

1. More than 5 million high-pixel cameras——for positioning feedback;

2. XYZ high-precision motorized slides——do motion scanning;

(The most ideal motion mechanism in the scanning direction is a linear motor)

3. U-axis rotating mechanism——do position compensation;

4. High-stability grating scales - do synchronous triggering (recommend Renishaw).

 

3DMeasure measurement software

 

3DMeasure measurement software is a general scanning measurement software specially developed by THINKFOCUS for 3D glass profile measurement. Height measurement and other functions.

The software can choose to use serial port or Ethernet to send the measurement results to the customer software, which can be further customized according to the specific needs of customers.

The software is highly open, and can configure different measurement schemes according to different needs of users, and can store scheme templates to facilitate users to replace products.

     

Measurement principle and process

  

1. Grab the sample boundary with a high-precision camera and perform angle correction. After the correction is completed, grab the sample boundary again to calculate the length and width and establish a coordinate system.

2. After passing the camera to produce the coordinate system, the motor drives the spectral confocal probe to move to the starting position of measurement, and sends a start signal. The spectral confocal probe sensor starts to move after receiving the ready signal, and the spectral confocal probe starts to move from The three angles simultaneously use the encoder frequency division signal to simultaneously capture the 3D glass surface contour curve of the sample, and output a complete contour curve after calculation and processing.

3. The contour curve is compared with the theoretical CAD contour line to obtain the contour result.

4. At the same time, it can measure the thickness, flatness, height and level difference of the specified position.

 

     

Measuring system composition

      img  

As a spectral confocal sensor manufacturer, THINKFOCUS only provides spectral confocal profile measurement sensor, programmable encoder frequency division module, 3DMeasure standard measurement software, SDK and dedicated PC processor in this measurement system.

The rest need to be integrated by the equipment manufacturer.

     

Software interface and functions

     

The schematic diagram of the measurement position can display the current scanning position in real time and output the final OK\NG result.
