The internal structure of Samsung's ultra-high-speed surface mount Technology (SMT) machine: Where do the precision and

Having been in the surface mount technology (SMT) industry for a long time, who hasn't heard of Samsung's ultra-high-speed SMT machines? That surface mount speed and that precision, to be honest, are beyond the reach of ordinary machines. But what exactly makes it so fast and accurate? When disassembled, every component and every system inside is basically designed to serve high efficiency and high precision, with no ambiguity in the design.

The core structure of Samsung's ultra-high-speed surface mount technology (SMT) machine is divided into several parts:

• high-speed XY motion platform
• multi-nozzle module
• dual-camera vision system
• vacuum system
• motion control unit

The XY platform is the foundation of the entire device, responsible for precisely moving the circuit board and the suction nozzle. The entire process must be both stable and fast.

The nozzle heads are not individual nozzles but a row. The common models are equipped with 6 to 10 suction nozzles and can handle a batch of components at one time.

The dual-camera system is respectively responsible for identifying the positioning points on components and PCB boards, serving as the "eyes" of the surface mount technology (SMT) machine.

Each part does not operate in isolation but works together to complete the entire mounting process.

During the movement of the suction nozzle, the camera can identify the posture and Angle of the components in real time. The surface mount head does not need to stop for identification, saving a lot of time. This approach is called Flying Vision.

Even for the extremely small 01005-sized components, the mounting error can be ensured to be controlled within ±0.03mm, ensuring both fast and accurate mounting.

Linear motors replace the traditional belt structure, bringing higher acceleration and smoothness. Combined with high-rigidity ball guides, the entire motion system does not shake or drift, and the positioning is precise to the micrometer level.

Moreover, it is equipped with a high-resolution encoder. Every detail of the movement has a "feedback closed loop", and once an error occurs, it will be immediately corrected.

The suction nozzle is the key execution point of the surface mount action. The nozzles of Samsung's surface mount technology (SMT) machines have the ability to automatically recognize and change models. They can automatically switch the type of nozzles according to the shape of the components, enhancing compatibility. The suction force can also be automatically adjusted. Light components will not be sucked away and heavy components will not fail to be sucked.

The fundamental reason for its high speed is not that a single nozzle dries quickly, but that multiple nozzles work in parallel. One action involves picking up 6 to 10 components and then attaching them all at once. It's all thanks to this parallel mechanism that tens of thousands of points can be posted every minute.

When the placement head is heading to the next component pick-up point, the camera has already started to recognize the component, and at the same time, the XY platform is also preparing for the next placement coordinate. The entire movement process is as tight as an assembly line, with not a single second idle.

The system will automatically plan the shortest and optimal placement path based on the position of the component on the feeder, the target placement position, and the type of component, reducing the idle movement time and improving the placement efficiency.

The vacuum module inside the surface mount technology (SMT) machine is not a simple suction pipe but a dynamic control system.

The vacuum strength will be automatically adjusted according to the size of the components to prevent poor adhesion or "deformation" during adhesion.

Once the suction nozzle fails to hold, it will trigger an automatic alarm or a re-suction process.

The vacuum pipeline adopts zonal control to ensure that the suction forces of multiple nozzles do not interfere with each other.

Steady absorption is the first step towards precise mounting.

Surface mount technology (SMT) equipment is about efficiency, but the prerequisite is that there must be no mistakes. In the control system of Samsung's surface mount technology (SMT) placement machines, a multi-core collaborative control architecture is adopted.

Each module independently handles its own tasks, such as visual processing, motion control, vacuum monitoring, and motor feedback, but at the same time can respond synchronously at the millisecond level.

Moreover, it is equipped with an internal environmental compensation system that can monitor the temperature changes during the operation of the equipment in real time, make fine adjustments, and ensure stability and no distortion at high speeds.

In terms of software, it's not just about having a good-looking operation screen.

• It features a powerful component library and nozzle parameter library, which can be imported with one click without the need for repeated Settings.
• The path optimization algorithm enables the device to determine the most time-saving mounting sequence by itself.
• Supports remote monitoring, error location, and efficiency statistics, facilitating management and maintenance.

These detailed functions are the key for the entire machine to maintain high production capacity during long-term operation.

The "speed" and "accuracy" of Samsung's ultra-high-speed surface mount technology (SMT) machines do not rely on a single component, but on the collaborative design of the entire system. From the structure of the suction nozzle, the motion platform, visual recognition, to vacuum control and software control, every module revolves around one goal: to stick quickly, accurately and without errors.

What's truly remarkable is not running fast, but remaining as steady as an old dog at high speeds.
