Principle and application of 3D profile measurement analyzer

Previously, Dacheng Precision’s technical staff has introduced the principles and applications of various thickness gauges. Today, Dacheng Precision’s technical staff will introduce the principles and applications of 3D profile measurement and analysis instruments.

In today's industrial production, in order to identify whether the burrs caused by welding are too large and whether the welding head needs timely maintenance, the 3D profile measurement and analysis principle is usually used to measure the product specifications, so as to ensure the final specifications and standard degree of the produced products. So among the many types of measuring instruments, why do we use 3D profile measurement and analysis instruments? What are the principles and applications of 3D profile measurement and analysis instruments? The following is the answer from Dacheng Precision's technical staff:

1. Typical applications:

The device can measure the morphology of the battery lug welding burr and the wave edge after the pole piece is stripped. The device can help identify whether the burr caused by welding is too large and whether the welding head needs timely repair.

2. Measurement principle:

The object to be measured is scanned using a high-precision 2D displacement sensor. After obtaining the relevant data of the surface profile of the object to be measured, various corrections and analyses are performed on it to obtain the required physical quantities such as height, taper, roughness, flatness, etc.

3. System Features:

1. Equipment used to measure microscopic three-dimensional morphology and surface feature analysis

2. Support one-click measurement and analysis, and automatically generate test reports

3. The system measurement height is adjustable to suit 3D measurement of samples of different thicknesses

Image application background: CE battery tab welding burr morphology measurement

4. Measurement accuracy:

1. Repeatability: ±1um (3σ)

2. X-direction resolution: 10um

3. Y-direction resolution: 10um

4. Z-direction resolution: 0.2um

5. Specifications of objects that the equipment can adapt to:

1. Effective measurement width ≤ 8mm

2. Effective scanning length ≤ 150mm

3. Height variation range ≤ 300um

From the above, we can know that 3D profile measurement and analyzer can be used in industrial sites to measure the morphology of battery tab welding burrs and the wave edge measurement after the pole piece is stripped. It is a high-precision thickness measurement device, which brings convenience to measurement. 3D profile measurement and analyzer has a long service life. It uses a high-precision 2D displacement sensor to scan the object to be measured. After obtaining the relevant data of the surface profile of the object to be measured, various corrections and analyses can be performed on the product to obtain the required height, taper, roughness, flatness and other physical quantities. It greatly improves the product production qualification rate and saves production costs.
