From the perspective of the development cycle, the international machine vision industry is currently in the mature stage. Against the backdrop of the global spread of the Industry 4.0 trend, industry experts predict that within the next 1 a 2 años, machine vision technologies in Europe, the United States, and Japan will further achieve pioneering innovations, and the scale of the international market will also continue to grow.

Case Studies Machine Vision Inspection

As a comprehensive technology, a complete machine vision application system consists of components such as an image capture module, a lighting system, an image digitization module, a digital image processing module, an intelligent judgment and decision-making module, and a mechanical control execution module.

Among these components, industrial touch display devices serve as the control and display center of the entire machine vision inspection system. They are crucial equipment for enabling the system’s external-connected industrial cameras/cameras to perform functions such as image display, inspection programming and setting, abnormal alarm, and data collection, and play an irreplaceable role.

So, in machine vision inspection applications, what are the user requirements for selecting industrial touch display devices? Let’s take the classic application cases of TouchThink Intelligent series as examples to find out!

Case 1: Machine Vision Inspection Solution for Battery Factories

Application Requirements:

In the battery factory case, the user’s machine vision inspection system adopts high-definition industrial cameras, which are mainly used for character recognition. This places higher configuration requirements on touch display devices: the devices must also be able to quickly and accurately capture and receive the inspected images, and the displayed images must be precise and high-definition.

Main Product Performance:

• In machine vision inspection, the panel PC must adopt the Windows operating system to meet the requirements for connecting external monitoring devices;
• Based on the user’s system using a 5-megapixel high-definition industrial camera, the configuration of the all-in-one machine needs to be upgraded to the I5-5200U processor, with 4GB of running memory and 128GB of hard disk storage respectively. This achieves faster response speed and significantly reduces latency;
• The built-in motherboard is independently developed, ensuring stronger overall machine stability and higher cost-effectiveness. Combined with the upgraded configuration, it can guarantee 24/7 high-load uninterrupted stable operation;
• It supports HDMI and VGA high-definition signal input. The captured images are displayed clearly and with high fidelity, and the image display frame rate can reach more than 30 frames per second without frame loss, which can meet the user’s needs for a high-definition image display interface;
• According to different visual inspection systems, it can be customized in terms of installation methods, special screens, module installation, and configuration upgrade requirements.

Case 2: 3D Machine Vision Inspection Application Solution

Application Requirements:

Since 2D machine vision inspection cannot measure an object’s flatness, surface angle, thickness, height, volume, and other dimensional parameters, the user has adopted a 3D machine vision inspection system. This system uses industrial cameras with standard resolution and is capable of inspecting low-contrast objects in scenarios such as constant contrast, insensitivity to minor lighting changes, or immunity to ambient light interference.

Key Product Performance:

• The product features an embedded installation design, with the front panel being only 3mm thick. This allows for seamless integration with the user’s equipment during installation, resulting in a more aesthetically pleasing appearance.
• Adopta un 16:9 screen aspect ratio and a 10-point capacitive touchscreen. The screen offers full viewing angles, delivering an enhanced touch operation experience. Mientras tanto, the capacitive touchscreen is more suitable for industrial environments with strong electromagnetic interference.
• The all-in-one machine achieves a display resolution of 1920×1080, ensuring clear images without ghosting. This meets the high requirements for precise and consistent image display in inspection scenarios.
• En este caso, the user employs a 1-megapixel industrial camera. The all-in-one PC, equipped with a standard configuration of J1900 quad-core CPU and 2GB RAM + 8GB storage, fully meets the application needs. With a turbo boost frequency of up to 2.0GHz, it enables high-definition image display without lag.
• The internal components of the all-in-one PC are sourced from internationally renowned brands, providing superior performance in explosion prevention, flame retardancy, surge protection, and electrostatic discharge (ESD) protección. This supports the long-term stable operation of the inspection system without obstacles.

Case 3: Fully Automated LCM Visual Inspection Solution

Application Requirements:

On traditional production lines, manual inspection methods not only fail to guarantee efficiency but also result in a relatively high product defect rate. The user has upgraded to a fully automated inspection system, where the control unit adopts industrial computer equipment. This equipment is required to save space, have good heat dissipation, high performance stability, support long-term operation, and be compatible with external devices such as monitors.

Key Product Performance:

• Pre-installed with the Windows 7 Sistema operativo, it features a compact size of 200×189×59 (milímetros), enabling easy and quick installation while saving more space.
• Equipped with a fanless strip grid design, it ensures external air circulation, improves heat dissipation efficiency, and operates more quietly.
• Configured with a Celeron J1900 quad-core CPU, 2GB of RAM, and 32GB of hard disk storage. With high-performance components including DDR3 memory and Realtek RTL811E network chip, it runs without lag, offers high overall reliability, and can continuously operate stably under high loads—effectively ensuring efficient product production.
• Supports power-on boot function, with strong environmental adaptability: it can operate within a wide range of temperatures and humidity, and has excellent dust resistance, resistencia a la corrosión, and anti-vibration/shock capabilities. Además, it boasts good electromagnetic compatibility (EMC) and high anti-interference performance.
• It comes with a complete set of interfaces, incluyendo USB, RJ-45, WIFI connectors, high-definition HDMI and VGA interfaces. It supports synchronous dual-display and asynchronous display functions, and can be customized to expand a variety of industrial-specific interfaces—fully meeting the needs of connecting external devices.
