3C product precision measurement, Hypersen spectroscopic confocal sensor empowers intelligent manufacturing

With the diversification of consumption and the iterative upgrade of product technology, the market segments in various fields of industrial manufacturing are also growing in a completely different situation. China's technological consumer electronics market is growing rapidly, and the high-end new technology products under the new ecological consumption will also Detonated the 3C market boom. As the core driving force of the development of technology and the Internet, the 3C market is developing rapidly. The compound annual growth rate of 3C products is expected to be 2.6% in the future. In 2019, the global total annual shipments of mobile phones, computers, and tablets are close to 4 billion units, of which mobile phone consumption is the largest. According to the "Analysis of China's 3C Automation Equipment Market Competitiveness in 2020-2026 and Investment Strategy Forecasts" published by CICC International Consulting According to statistics from the Research and Development Report, it may reach 1.522 billion units by 2026.

 

Nowadays, the rapid development of artificial intelligence and 5G technology has provided continuous vitality for the industrial manufacturing industry. The application of new technologies and new equipment has prompted the main body of 3C production and manufacturing to move towards a faster product change cycle and higher-efficiency production and manufacturing capabilities. , Higher-quality product quality control and product management, these also drive the development of intelligent manufacturing in the 3C electronics industry to a new level. China is a major 3C manufacturing country, accounting for 70% of the global production capacity, of which mobile phone manufacturing capacity is the highest (32%), which means that most of the processing and assembly plants for 3C products are in China. The trend of miniaturization and complexity of electronic components such as mobile phones, notebooks, and LCD TVs has put forward higher requirements for the accuracy, accuracy and efficiency of industrial quality inspections, and the rising labor costs in China have also accelerated the trend of "machines for people". , Machine vision can use machines instead of human eyes to do measurement and judgment, apply image processing in the field of industrial automation, and perform non-contact detection and measurement of objects, thereby improving processing accuracy, discovering product defects, and making automatic analysis and decision-making. This is in industry The application in the field of automated production is becoming more and more extensive.

 

Machine vision is widely used in the field of intelligent manufacturing, and is mainly divided into four categories according to its functions: detection, measurement, positioning, and recognition. Especially in the 3C industry, electronic components have the characteristics of small size, many types of surface defects, and complex product materials. The 3C product appearance defect detection system can realize automatic detection of internal and external defects, including whether the main parts are present or not, screws Whether there are scratches on the glass plate, size measurement, chromatic aberration, etc. With the upgrading of production technology, its requirements for accuracy are gradually increasing. 2D detection is gradually upgraded to 3D. Through detection, the width, height, convex area, concave area, convex volume, concave volume and other information of the target can be obtained. The detected dents and slight dents can be accurately detected. In addition, in industrial manufacturing, product production often relies on high-speed mass production production lines, which puts forward greater requirements for inspection efficiency, and equipment must complete specific tasks during high-speed motion.

 

As one of the national high-tech enterprises in the production and manufacture of high-end smart sensors in China, Hyberson focuses on the field of machine vision precision measurement, helping the industrial manufacturing industry to improve its precision measurement capabilities and empowering industrial manufacturing. Heberson HPS-LCF1000 is the country’s first 3D line spectrum confocal sensor. It adopts the principle of spectral confocal. It calculates the wavelength of the detected focal point and converts the distance value. Therefore, the product has 3D detection imaging analysis, horizontal and vertical The advantages of high resolution, fast sampling rate, and strong anti-interference security. For 3C electronic product testing, its internal materials are complicated, especially some highly reflective and transparent materials. Traditional testing methods cannot meet the needs of industrial-grade high-precision testing. If the operating efficiency of the testing equipment is improved, the accuracy will be higher, and the stability will be stronger. Then the increase in yield will inevitably lead to a substantial increase in output.

 

The display screen is an important part of 3C electronic products. Just in April this year, a consumer electronics manufacturer released a new 12.9-inch tablet computer equipped with a Mini LED backlight display screen. Then in July, domestic industrial manufacturing giants also launched The self-developed Super Mini LED precision matrix backlight solution product has opened the curtain of domestic Mini LEDs moving towards commercial mass production. Mini LED refers to an LED chip with a size on the order of 100 microns. The size is between small-pitch LEDs and Micro LEDs. It is the result of the continued shrinking of small-pitch LEDs. Large-scale application, and the development of this new technology will inevitably face the problem of improving panel yield. How to achieve micron-level precision measurement requires more sophisticated intelligent testing equipment to empower industrial intelligent manufacturing.

 

3C product dispensing is indispensable. Most dispensing occasions are to reduce the risk of chip solder joints cracking and chip circuits being pulled apart due to vibration, because the chip itself is located in a weak area on the PCB, when the phone falls , The PCB will oscillate back and forth, cracking the solder joints, and then the chip circuit will be pulled apart under the force. As a breakthrough non-contact sensor in the field of high-precision 3D measurement, the HPS-CF series of Heberson products are not affected by the surface of the measured object during the scanning process, and can accurately measure any object with high reflection, strong light absorption and transparent material. , The detection accuracy can reach micron level, and the minimum accuracy can reach 2um. Compared with the traditional measurement method, the spectral confocal sensor uses a special lens to generate spectral dispersion, and will not cause the problem of light refraction during the scanning process due to the reflection on the surface of the object, ensuring measurement stability, so it has high speed, high precision and high adaptability. Obvious advantages such as sex. In the field of 3C electronics, common dispensing applications include PCB board dispensing/chip coating breakage, lack of glue overflow, etc. In addition to transparent colloids, Heberson 3D line spectrum confocal sensors can also be used to detect high-reflectivity Surface defects, such as mobile phone glass warpage, surface impurities and scratches, etc.

 

Up to now, Hyberson has developed China’s first 3D line spectrum confocal sensor, as well as point spectrum confocal displacement sensor, ultra-high-speed industrial camera, six-dimensional force sensor, laser needle sensor, area array solid-state lidar, and laser triangle A variety of products such as displacement sensors and single-point ToF ranging sensors can meet the diverse detection needs of different industries such as industrial automation, Internet of Things, AGV, robotics, intelligent transportation, consumer electronics and drones. In the future, Hyperion technology will follow the development trend of the times, continue to dig deeper into the field of high-end sensor R&D and manufacturing, and continue to introduce new ones. Hyberson is committed to upgrading domestic sensor technology and import substitution of high-end products, helping my country's industrial manufacturing industry to shift from low-end to high-end, thereby achieving higher-quality manufacturing in China.
