What are the accessories for Hanwha's surface mount technology (SMT) placement machines? Analysis of the functions and r

Friends who are engaged in SMT should all know that Hanwha's surface mount technology (SMT) placement machines are widely recognized in the industry as "cost-performance experts". The machine itself is stable and highly efficient. But to make it run fast and stable, having only the main unit is not enough; all kinds of accessories are the "soul" of the entire system. These fragmented components, though not eye-catching, each play a crucial role.

Today, let's not delve too much into theory. Let's get down to business - What are the common accessories of Hanwha's surface mount technology (SMT) placement machines? What are they all used for? How many do you know?

1. Feeder: The "transporter" of the surface mount technology (SMT) machine

   When it comes to accessories, Feida is definitely the one with the highest appearance rate. Its task is very clear - it is responsible for delivering the components in the material tape one by one to the "mouth" of the suction nozzle, and the positioning must be accurate and the rhythm in harmony.

   Hanwha's Feida is available in different widths such as 8mm, 12mm, 16mm, and 24mm, catering to various tape sizes. The most commonly used one is the 8mm Feida, which is used to apply small materials like 0402 and 0603.

   The key role of Feida:
   • Control the feeding rhythm
   • Ensure the precise position of components
   • It directly affects the mounting speed and the yield rate

   If a surface mount technology (SMT) machine is without a feeder, it's like a chef without a cutting board, and nothing can be done.

   
2. Nozzle: The "Key Player" for Mounting Accuracy

   The nozzle is the most "delicate" component in the surface mount technology (SMT) process, and its function is simple and straightforward - to pick up components, move them, and precisely place them on the PCB. It looks easy, but the actual operation is not at all ambiguous.

   There are different models of suction nozzles, corresponding to components of different sizes. For instance, when applying 0201, an ultra-small diameter suction nozzle is required, while for BGA, a dedicated suction nozzle with strong suction power and high stability is needed.

   The core function of the suction nozzle:
   • Adsorption elements are transmitted to the specified coordinates
   • Determine the absorption accuracy and mounting position
   • The requirements for vacuum degree and accuracy are particularly high

   A small reminder: The suction nozzle is prone to clogging and wear after long-term use. Regular inspection and cleaning are necessary; otherwise, problems such as misalignment and falling parts may occur.

3. Feeder Base: Feeder's "Stage"

   This accessory is often overlooked by many beginners. In fact, when the Feida is installed, it doesn't hang out of thin air but is fixed on the feeding frame.

   The function of the feeding frame is to ensure the stable positioning of the Feida and maintain the consistency of the feeding trajectory. If there is a problem with the feeding rack, such as loose clips or misaligned slide rails, it will affect the operation rhythm of the entire line.

   Some models also support "Intelligent Feida recognition", which relies on the recognition module on the feeding rack.

4. Vacuum pump/vacuum generator: The core equipment that provides "suction power"

   The reason why the surface mount technology (SMT) machine can pick up components is not by "magic", but by the vacuum system behind it.

   The Hanwha surface mount technology (SMT) machine has an independent vacuum module inside, which could be a vacuum pump controlled by an electromagnetic valve or a negative pressure generator.

   The function is summed up in one sentence: to supply air to the suction nozzle, ensuring it has sufficient suction to firmly grasp the components.

   If the vacuum is insufficient, it marks the beginning of unstable suction, component dropping, and misalignment.

5. Sensor: The "Eyes" of the Surface Mount Process

   Despite the high-speed operation of the surface mount technology (SMT) machine, every step is actually controlled by sensors - photoelectric sensing, position sensing, vacuum detection... None of them can be missing.

   The common sensors in Hanwha surface mount technology (SMT) machines include:
   • Component suction sensor: Confirm whether the suction nozzle has successfully lifted the component
   • Feida feeding sensor: Detects whether the feeding is normal
   • Positioning sensor: Ensures that the X/Y axis movement is in place

   Once the sensor malfunctions, it can easily lead to false alarms or misjudgments, such as "clearly absorbed, but it shows no absorption".

   
6. Motor and Drive System: The "Power Heart" of Surface Mount Technology (SMT) Machines

   All the movements, rotations and elevations inside the Hanwha surface mount technology (SMT) machine are driven by motors. For example:

   • The movement of the X/ Y-axis motor control platform
   • The Z-axis motor controls the up and down movement of the suction nozzle
   • The feeding action is controlled by Feida motor

   Behind these motors, there are servo drivers for control and feedback. Once any motor malfunctions, the entire device may break down.

7. Guide Rail system: The navigator that keeps PCBS on the right track

   During the surface mount technology (SMT) process, the PCB needs to move from left to right or from front to back, and this process is achieved through rails.

   The guide rail is not only responsible for "transporting" the PCB, but also needs to be precisely aligned with the mounting area.

   Some models are equipped with an automatic width adjustment function, which can adapt to PCBS of different sizes, relying on the precise control of the guide rails.

8. Belts & Synchronous Pulleys: The "Old Ox" of Transmission Systems

   Many movements, such as the movement of the platform and the rotation of the suction nozzle, actually rely on the transmission of belts and synchronous pulleys.

   Don't underestimate this pair. Once the belt becomes loose or the wheels slip, the entire precision will deviate. Although they don't break down much, once there's a problem, it's like a "whole line going on strike".

   
9. PCB Positioning PIN/top pin: A tool for fixing the position of the PCB

   This accessory is often overlooked, but in fact, its role is very crucial - after the PCB is loaded, it precisely positions itself to prevent movement or deviation.

   Especially on boards with double-sided mounting and many irregular components, positioning pins can effectively prevent problems such as misalignment and tilting.

10. Industrial Control Motherboard/IO board: The Brain and Neural Network of Surface Mount Technology (SMT) machines

    In essence, a surface mount technology (SMT) placement machine is also a "high-end computer". The main control board and IO board inside are like the "brain + nervous system", responsible for controlling movement, signal reception, logical judgment, etc.

    Although it is not a vulnerable part, once it malfunctions, the troubleshooting process becomes rather complicated and requires the assistance of professional maintenance engineers.

The reason why Hanwha's surface mount technology (SMT) placement machines can run steadily and accurately is actually inseparable from the cooperation of every "small accessory" behind the scenes. Feida, suction nozzle, sensor, motor... Each component performs its own function and none can be missing.

So, whether you are an equipment maintenance worker, an engineer or a purchaser, understanding the functions of these accessories is the first step to improving efficiency and reducing the failure rate.

Don't be afraid if you don't understand the accessories. Only when you do can you use them smoothly. Don't wait until the equipment malfunctions to look up information. It's better to figure it out now and have a clear understanding, which will make the production line more at ease!
