What are the new technology applications of smart SMT pick and place machines.

Intelligent SMT (Surface Mount Technology) mounter is one of the core equipment in modern electronics manufacturing and is widely used in component mounting on PCB (Printed Circuit Board). With the rapid development of Industry 4.0, artificial intelligence, the Internet of Things and other technologies, intelligent SMT mounters are also constantly introducing new technologies to improve production efficiency, accuracy and flexibility. Our Nectec team will analyze the benefits and development trends of some new technology applications in smart SMT mounters to the SMT industry, so as to more accurately help our future potential customers choose our SMT high-tech equipment. 

The first application we want to discuss is computer vision and AI. Computer vision is one of the key technologies of intelligent SMT mounters. It uses high-resolution cameras and image processing algorithms to accurately identify and locate components, PCB boards and mounting positions. In recent years, the introduction of artificial intelligence technology has further improved the capabilities of computer vision. Its technology has two core technology cornerstones represented. The first is deep learning algorithm: Through deep learning algorithm, intelligent SMT mounter can automatically identify and classify different types of components, even when the components are complex in shapes or are not marked. In the case of clear, high-precision identification can also be achieved. In addition, AI can also analyze historical data to optimize the mounting path and reduce the mounting time; the second is defect detection: AI technology can help the mounter detect defects in real time during the mounting process, such as misplacement, missing or damage of components. Through machine learning, the system can continuously optimize detection algorithms and improve the accuracy and efficiency of defect detection.

The second application we want to discuss is high-precision motion control. The placement accuracy of the mounter directly affects the quality of the PCB board. As electronic components become more and more miniaturized, the requirements for motion control of mounters are becoming higher and higher. This control system has two representative technical cornerstones. The first is linear motors and servo systems: Modern intelligent SMT mounters generally use linear motors and high-performance servo systems, which can achieve nano-precision motion control. Linear motors have the characteristics of fast response speed and high positioning accuracy, which are especially suitable for high-speed and high-precision mounting requirements; the second is multi-axis linkage control: mounters usually need to control multiple motion axes at the same time, such as X, Y, Z axis and rotation axis. Through multi-axis linkage control technology, the mounter can realize complex mounting actions and improve mounting efficiency and accuracy.

The third application we want to discuss is IoT and big data analysis. The introduction of Internet of Things technology enables smart SMT mounters to seamlessly connect with other manufacturing equipment and management systems to achieve data sharing and collaborative work. This special technology has two core functions. The first is real-time monitoring and remote control: Through the Internet of Things technology, the operating status, mounting data, fault information, etc. of the mounter can be uploaded to the cloud in real time for managers to monitor and analyze remotely.

When an abnormality occurs in the equipment, the system can automatically alarm and even remotely diagnose and repair faults; the second is big data analysis: the mounter will generate a large amount of data during operation, such as mounting speed, accuracy, and component usage. situation, etc. Through big data analysis, companies can optimize production processes, predict equipment failures, and reduce production costs. To give a real example, Nectec’s old customers analyzed the mounting data and found that the mounting success rate of some components was low. They then adjusted the mounting parameters and replaced the components in a timely manner according to needs.

The fourth application we want to discuss is flexible manufacturing and modular design. With the increasing demand for diversified electronic products, intelligent SMT (Surface Mount Technology) pick-and-place machines need to exhibit higher flexibility to accommodate the production needs of different products. This flexibility manifests in two aspects. The first aspect is modular design: modern pick-and-place machines typically adopt a modular design, allowing customers to flexibly configure different functional modules according to production needs, such as high-speed mounting heads, high-precision mounting heads, dispensing modules, etc. This design not only enhances the flexibility of the equipment but also reduces maintenance costs. The second aspect is rapid changeover technology: to adapt to the production model of multiple varieties and small batches, intelligent SMT pick-and-place machines have introduced rapid changeover technology. By automatically replacing suction nozzles and adjusting mounting parameters, the pick-and-place machines can complete the switch to different products in a short period of time, reducing downtime. 

The fifth application we want to discuss is 3D printing and additive manufacturing. Although 3D printing technology is primarily utilized for prototyping and low-volume production, it is also starting to make an impact in the field of SMT (Surface Mount Technology) pick-and-place machines. The Nectec research team has identified two applications of 3D printing technology in the SMT domain. The first is customized suction nozzles and fixtures: SMT manufacturers can swiftly produce customized suction nozzles and fixtures using 3D printing technology, accommodating components of unique shapes or sizes. This approach not only shortens the manufacturing cycle but also reduces costs. The second application is additive manufacturing for repairs: Precise components within pick-and-place machines may experience wear or damage over prolonged use. With additive manufacturing technology, local repairs can be conducted without replacing the entire component, thereby extending the equipment’s lifespan.

The sixth application we want to discuss is green manufacturing and energy-saving technology. With the increasing awareness of environmental protection, intelligent SMT surface mount machines are gradually introducing green manufacturing and energy-saving technologies. The first energy-saving technology is energy-saving motors and drivers: modern surface mount machines commonly use energy-saving motors and drivers to reduce energy consumption through optimized control algorithms. For example, when the SMT machine is idle, the system can automatically reduce the motor speed or enter standby mode to reduce power consumption; The second energy-saving technology is the use of environmentally friendly materials and processes: In the manufacturing process of surface mount machines, more and more companies are starting to use environmentally friendly materials and processes, such as lead-free solder, low volatile organic compound (VOC) coatings, etc., to reduce their impact on the environment.

The seventh application we want to discuss is augmented reality (AR) and virtual reality (VR). Augmented reality and virtual reality technologies are gradually being applied to the operation and maintenance of intelligent SMT surface mount machines. Firstly, AR assisted operation is generally achieved through AR glasses or tablet devices, where operators can see virtual operation prompts and fault diagnosis information in the actual working environment of the surface mount machine, thereby improving the accuracy and efficiency of the operation. Then, VR training and simulation are generally conducted through VR technology. Enterprises can provide virtual SMT machine operation training for new employees, so that they can familiarize themselves with equipment operation and fault handling in a virtual environment, reducing errors in actual operation. Although these two technologies are similar, the actual techniques used and the learning knowledge and experience they can provide to employees are completely different.

To conclude, as the core equipment of modern electronic manufacturing, intelligent SMT surface mount machines are constantly introducing new technologies to improve production efficiency, accuracy, and flexibility. The application of machine vision and artificial intelligence, high-precision motion control, Internet of Things and big data analysis, flexible manufacturing and modular design, 3D printing and additive manufacturing, green manufacturing and energy-saving technology, augmented reality and virtual reality and other technologies enables intelligent SMT surface mount machines to better adapt to the diversified and miniaturized production needs of electronic products, promoting the development of the electronic manufacturing industry towards intelligence and green direction.

In the future, with the continuous advancement of technology, intelligent SMT surface mount machines will continue to play an important role in the field of electronic manufacturing.
