Publish Time: 2025-07-14
With the continuous development of LED display technology, especially driven by emerging application fields such as Mini LED and Micro LED, higher requirements are put forward for the packaging accuracy and production efficiency of LED backlight chips. In this context, as a key equipment for high-precision and high-efficiency chip mounting, the technical advantages of mini LED backlight die bonding machine are becoming increasingly prominent.
1. Advanced structural design to improve overall performance
Mini LED backlight die bonding machine generally adopts double-arm and four-arm structural design, integrating advanced technologies such as precision mechanical system, machine vision, motion control and intelligent algorithm. This multi-arm collaborative structure not only improves the operating efficiency of the equipment, but also enhances the stability and reliability of the system, enabling it to adapt to the needs of high-speed and high-precision chip mounting and meet the high-quality production standards of modern LED backlight modules.
2. High-performance drive system to achieve high-speed and high-precision mounting
The mounting head of the equipment is jointly driven by servo motor and voice coil motor, with fast response speed and precise positioning, and can achieve micron-level mounting accuracy. This high-precision motion control system not only improves the efficiency of patching, but also effectively reduces the chip loss caused by errors and improves the product yield. It is especially suitable for the mounting process of small-size, high-density LED chips.
3. Intelligent visual system to improve mounting accuracy and consistency
The mini LED backlight die bonding machine is equipped with an advanced bottom flight visual system, combined with a 360° rotating swing arm structure, which can capture the position and angle information of the chip in real time, automatically correct the angle, and ensure the accuracy of the mounting position. At the same time, the system can also identify the polarity and angle error of the chip to avoid mounting failures caused by incorrect chip direction, significantly improving the consistency and stability of the patch.
4. Efficient crystal ring platform, supporting automatic switching and angle correction
The high-speed and high-precision crystal ring platform is an important part of the bonding machine. The platform not only has the function of automatically switching the crystal ring position, but also can automatically correct the chip angle during the switching process to ensure that the chip is in the best state before mounting. In addition, the platform also supports the automatic replacement of crystal rings, which greatly reduces manual intervention and improves the automation level and production efficiency of the equipment.
5. Linear motor drive + laser height measurement to achieve higher patch accuracy
The patch platform adopts a high-speed linear motor drive system, combined with a laser height measurement function, which can measure the height difference between the chip and the substrate in real time, so as to accurately control the patch force and position. The application of this technology effectively improves the flatness and consistency of the patch, avoids problems such as false sticking and offset caused by height error, and is particularly suitable for Mini LED backlight chip mounting with extremely high precision requirements.
6. Automatic correction of the ejection module to improve mounting accuracy
During the chip mounting process, the accuracy of the ejection module directly affects the final mounting quality. The ejection module of the mini LED backlight die bonding machine has an automatic correction function in the XY direction, which can fine-tune the chip position before mounting to ensure that it is accurately mounted at the target position, further improving the overall mounting accuracy and yield rate.
7. Rotatable loading and unloading table to improve production capacity and compatibility
In order to improve the overall production capacity of the equipment, the bonding machine adopts a rotatable loading and unloading table design. This design not only improves the efficiency of loading and unloading, but also enhances the compatibility of the equipment with substrates of different sizes and models, so that the equipment can flexibly respond to various production needs and meet the mounting process of diversified products.
8. Leakage detection function to ensure production quality
The equipment also has a leakage detection function, which can monitor whether the chip is mounted normally in real time during the mounting process, and promptly detect the situation of missing mounting or mounting failure. The addition of this function effectively avoids the scrapping of products due to missing chips, improves the overall production yield, and reduces quality risks.
9. Intelligent software system, easy and efficient operation
The software system of mini LED backlight die bonding machine has high integration, friendly interface, easy operation, and supports the setting and adjustment of multiple process parameters. At the same time, the system has intelligent learning and data analysis capabilities, which can optimize the mounting path and parameter settings according to historical data, and improve the intelligence level and production efficiency of the equipment.
In summary, mini LED backlight die bonding machine has become an indispensable core equipment in LED backlight manufacturing with its advanced structural design, high-speed and high-precision mounting capabilities, intelligent vision and control system, and efficient production compatibility and detection functions. It not only significantly improves the accuracy and efficiency of chip mounting, but also provides a strong guarantee for the large-scale, high-quality production of LED backlight modules.
