Business background

With the development of technology, more and more products tend to be smaller, compact, portable, and even more integrated, which requires some components to be more miniaturized. Very small devices, including screw fasteners, electronic components, tiny rubber products, etc. For the inspection of these very small components, the traditional manual inspection mode has been unable to meet the needs of production. The emergence of machine vision system has replaced the cumbersome traditional labor force, and it has conformed to the current quality improvement and efficiency of intelligent manufacturing. Especially in some refined processes and high-risk work environments, the detection rate is low, and labor is laborious . The use of machine vision greatly improves the accuracy of detection and work efficiency.

Industry Status

The reason why visual inspection can perfectly replace manual in the inspection control of contemporary manufacturing is that the machine's fixed algorithm can achieve fatigue-free, stable and continuous work, and achieve accurate and error-free operation requirements. However, in practical applications, a series of business processes from visual input to digital information transmission, as well as machine response and control actions, all need to rely on powerful computing capabilities, which has also become a barrier in industrial visual inspection.

For very small devices, to achieve high-speed visual inspection to meet consumer demand, the requirements for algorithm accuracy, computer computing power, real-time communication, and long-term stable operation of the whole machine are particularly high.

Applications

Apqi worked with a domestic company focused on automation solutions for the passive component production industry to achieve 6-sided inspection of extremely small components, through high-magnification CCD industrial cameras, industrial lenses, professional light source systems, and more than 7 cameras, With WGD special detection software, it can realize high precision and high speed detection of 5 ~ 50mm ultra-small device-less. The system composition is as follows:

In the entire system, in order to meet the calculation requirements of multi-channel, high-speed calculation and real-time response, the company put forward the following requirements for new embedded computers:

A. Requires more than i5 computing power

B. Support more than 7 industrial camera connection capabilities

C. Require compact and small volume

D. Require anti-vibration, adapt to high temperature work

Product application import

Apqi combines the company's business requirements and application environment through the modular product E7 to do application import. The E7 series adopts a new-generation Skylake platform full-performance desktop-level processor (6/7 th), equipped with Q170 industrial-grade chips, combined with the Intel Media SDK to achieve multi-channel graphics operations, and through excellent heat dissipation and power design, integrated discrete graphics In the embedded chassis, its modular design and powerful expansion ability can be quickly applied to machine vision, Internet, AGV, big data and other application fields. In this project:

➤Using Intel i5-6500 to realize the high-speed calculation of the fine size of small devices and multi-camera images, the highest accuracy can reach ± ​​0.01mm, and the speed can reach 1200 non-device high-speed detection screening per minute

➤Through the MXM module and aDoor to achieve 8 intel Gigabit networks, and support jumboframe, to achieve 6 + 1 + 1 vision applications, through 6 cameras to do the appearance inspection of components, a prototype to do the precision measurement of the size A prototype is used for screening control;

➤E7's compact body is more suitable for installation in narrow spaces, and it complements each other in precision systems such as component inspection equipment;

➤Uniquely designed copper tube + large area aluminum fin + PWM intelligent fan cooling system allows E7 to run stably for a long time in a small space under the component inspection table;

➤The aluminum alloy case formed by the mold can effectively resist shock vibration in the component screening shaker;

➤The wide-voltage power input module can share the power environment with servos, PLCs and other equipment, and resist EMI interference from industrial scenes such as shocks and surges.
