Structural glue path width, height and glue break detection application plan

This program uses the laser cross-section of the adhesive strip and the substrate as input to calculate the width, height, center position and cross-sectional area, and then combines the scanning position to check for adhesive breakage, collapse and changes along the way.

Tasks and image input

It is only possible to determine whether glue exists, but cannot confirm the glue amount and cross-sectional shape; wet gloss glue, transparent glue and highly reflective substrates can also easily cause multiple reflections.

Input data: strip/base calibration profile, position along the process, actual material and normal, broken glue, offset, collapse and excess samples.

Algorithm processing and output

Base positioning → Strip section segmentation → Width and height/center/area calculation → Continuity along the way and identification of missing measurements.

Output results: width and height curve, offset, glue break position and length; volume is only calculated when the boundary, base and coverage are complete.

Implementation and verification

Establish formulas according to adhesive materials and substrates, adapt to contour input, scan synchronization, exception output and traceability reports.

Verification method: compare dimensions with independent profiler/section reference, check missed detections/false alarms according to abnormality categories; test transparency, rotation angle and speed change separately.

Applicable boundaries and existing basis

The shape of the glue line cannot prove the sealing or bonding strength; a single cross-section is not equal to the volume of the entire glue line.

The cross-section basic module is available, but the glue/base segmentation, complete scanning and real glue material effects have not yet been accepted.

Corresponding algorithm:Laser line extraction and cross-section geometry measurement algorithm;Laser line scanning topography and surface geometry analysis algorithm。

Industry public information reference

The following content is used to illustrate the systematic division of labor of similar tasks in public industry materials. The original project does not belong to Jishi Technology, and the original data parameters are not converted into the performance commitment of this page.

Third-party public information · Micro-Epsilon

Micro-Epsilon: automotive glass trim glue path inspection

The original application data describes the use of scanCONTROL to measure the height, width and relative position of the automotive glass trim strips, and then form a tolerance result.

References to this program:The glue path algorithm should simultaneously define the base, position and cross-section amount, rather than just determining whether there is glue; the real material and reflection conditions are still project inputs.

Reference boundaries:The resolution/measurement frequency of the original data is not cited as our own parameters, nor is the glue path geometry inspection written as proof of sealing or bonding strength.
