Development trend of automatic image measuring instrument

In recent years, with the rapid transformation of the national equipment manufacturing industry, the development of the image measurement instrument industry has been greatly promoted. The measurement technology has changed from mechanical contact comparative measurement to non-contact image measurement; The measurement accuracy has also reached 0.001 mm, even 0.0005 mm more than the traditional 0.01 mm; The measuring efficiency has changed from simple manual to full automatic high-speed measurement; The measurement range has developed from ordinary processing measurement to miniaturization and miniaturization of circuit boards and LCD panels. With the rapid development of optical electromechanical integration and integration technology, a large number of applications of image measurement have become the development trend of Measuring Instrument industry.

Technical characteristics of modern image measuring instruments.

Imager manufacturers have developed from the past mechanical measurement to the current highly integrated optical electromechanical non-contact image measurement technology. Compared with traditional measuring instruments, non-contact optical imaging measuring instruments have the following main characteristics:

1. Multiple measurement methods: non-contact optical image measurement
The traditional measurement method is contact measurement, such as mechanical vernier caliper and micrometer; Modern measurement methods are various, and in recent years, measurement technologies such as laser scanning measurement and optical image measurement, especially optical image measurement, have been promoted and applied. By using sensor technology, electronic technology, software technology, optical CCD imaging and other comprehensive disciplines and technologies, image processing, analysis and detection of the tested product are carried out, effectively solving the impact of human factors on product uncertainty, and improving the accuracy, detection and degree of the product.
2. High precision image measurement: the measurement accuracy level has been improved from the traditional millimeter, micrometer to nanometer.
The traditional testing method mainly uses steel ruler, vernier caliper, micrometer and other commonly used testing instruments to measure measurement items. The measurement accuracy can only reach the millimeter, Z-micron level, and the measurement accuracy is low, which can not meet the development needs of modern mechanical equipment manufacturing industry. Through scientific image processing analysis and calculation methods, non-contact image measurement can reach the precision level of micrometer and nanometer, improve the detection accuracy, and provide reliable guarantee for the development of manufacturing industry.

3. Efficient testing: Automatic large-scale testing Traditional detection methods are manual and single piece detection. If large-scale production is required, comprehensive inspection is required, which will lead to low detection efficiency and increase artificial uncertainty. The non-contact optical image measurement will greatly improve the efficiency and accuracy of detection through full automatic servo control and reasonable tooling detection tools. It can detect dozens of products, even more products, every minute, which is especially suitable for batch production and detection.

4. Diversity of measurement range: the same instrument can detect various elements, such as length, angle and roundness
Traditional detection tools mainly detect length dimensions, such as steel ruler, vernier caliper and micrometer of German Brooke spectrometer. In order to detect roundness and angle, other special measuring tools must be replaced. The non-contact optical image measuring instrument can simultaneously detect multiple elements such as length, angle and roundness to meet the customer's all-round testing requirements.

Development trend of image measuring instruments
Optical electromechanical integration technology has penetrated into various disciplines and fields, becoming a new discipline and gradually becoming an industry. These industries are increasingly valued by new economic growth points.
From the perspective of the world's scientific and technological development, the fully automatic high-precision image measuring instrument combined with the optical electromechanical integration technology has its own non-contact measurement, high precision, high efficiency and wide measurement range. include:

(1) Modularization: In order to ensure the large-scale production of image measuring instruments, it is necessary to consider the generalization and modularization of product design in the design. Different products can be used interchangeably and borrowed. Each module has a single function, which is convenient for disassembly and maintenance. Functional substitution, etc; At the same time, mechanical, software and electrical components penetrate each other, and are independent and easy to maintain.
(2) Online: With the development of factory automation, the application of robot will be more and more extensive. How to realize the automatic production of the factory, how to ensure the stability of product quality, and the online detection of factory automation will also be more and more popular. Online detection and recognition systems, such as image measurement instruments, also ushered in the spring of their development.
(3) Integration: With the rapid development of China's national economy, various technologies at home and abroad continue to penetrate, including high-precision processing, optical technology, microelectronics, software technology, sensor technology and laser technology. With the continuous learning and integration of advanced technologies, image measurement instruments have also developed into advanced detection instruments integrating various disciplines.
The development of high-precision image measuring instrument industry is not only the demand for the development of national equipment manufacturing industry, but also the demand for the development of measuring instruments. This is also the demand for the actual work of most instrument manufacturers and users, and will bring considerable economic value to the country, society and individuals.
