Thread inspection has always been a challenging task in industrial production. Traditional measurement methods are often limited by operation complexity, measurement accuracy and efficiency, which are difficult to meet the modern manufacturing industry's pursuit of high quality and efficiency. As an advanced non-contact measurement technology, laser alignment measurement solution is gradually becoming the new favorite in the field of thread inspection.

Principle of the laser alignment measurement program

The core of the laser alignment measurement solution lies in the use of infrared laser technology to achieve high-precision distance measurement and target positioning. The solution emits a precise spot beam through a laser transmitter. When the beam is blocked by the target object, the receiver will not receive the laser signal, thus triggering an alarm or measurement action. In thread inspection, this principle is skillfully applied to measure the size and shape of threads. By adjusting the angle and position of the laser beam, precise scanning and measurement of all parts of the thread can be realized.

The POMEAS In-Line Image Gauge uses a similar principle, but goes one step further by combining it with image processing technology to achieve real-time capture and precise analysis of the thread profile. This combination not only improves the accuracy and efficiency of the measurement, but also greatly simplifies the operation process, making thread inspection more convenient and reliable.

Difficulties in thread measurement

1. Structural complexity: the thread structure is complex and variable, including different pitches, tooth angles and thread depths, etc., and the changes in these parameters increase the difficulty of measurement.

2. High accuracy requirements: the accuracy of thread size is directly related to the quality and performance of the product, so the measurement must meet the requirements of high accuracy.

3. Measurement environment interference: In the actual production environment, threads are often covered by oil, dust and other pollutants, and these interfering factors will affect the accuracy and stability of measurement.

Advantages of laser alignment measurement solutions

1、Real-time and fast measurement: The laser alignment measurement solution can realize real-time and fast measurement of thread size, which greatly improves the inspection efficiency.

2、High-precision Measurement: Since the laser has a high degree of directionality and accuracy, the laser alignment measurement program can provide extremely high measurement accuracy to meet the high requirements of thread inspection.

3、Non-contact measurement: The laser alignment measurement program adopts the non-contact measurement method, avoiding the contact wear and error accumulation problem in the traditional measurement method.

In the practical application, the laser alignment measurement program carried out accurate measurement of threads. The results show that the program can accurately measure key parameters such as thread pitch, tooth angle, thread depth, etc., and the measurement accuracy is as high as ±0.01 mm.This result fully proves the reliability and accuracy of the laser alignment measurement program in thread inspection.
