High-speed dispensing mounter how to achieve efficient and accurate dispensing and patch
I. Advanced mechanical structure design
High rigidity body: High-speed dispensing mounter adopts high-strength aluminum alloy or cast iron to build the body, after precision machining and aging treatment, it has good rigidity and stability. In the process of high-speed movement, the body can effectively resist vibration and deformation, providing a solid foundation for the accuracy of dispensing and placement. For example, some high-end equipment body structure design, can ensure that in high-speed operation, the platform displacement error control in a very small range, to ensure the consistency of dispensing and placement.
High-precision transmission system: The equipment is equipped with high-precision ball screws and linear guides, which accurately convert the rotary motion of the motor into linear motion. The precision of these transmission components is up to micron level, which makes the positioning of dispensing head and patch head in X, Y, Z axis direction more accurate. At the same time, the high-performance motor provides strong power output to ensure that in high-speed operation can also respond quickly to the instructions, to achieve efficient dispensing and patch operation.
Second, high-precision control system
Motion Control Algorithm: Advanced motion control algorithm is the core of high-speed dispensing and mounter to realize efficient and accurate operation. Through the precise control of motor speed, acceleration and position, the equipment can realize fast dispensing and patching action under the premise of ensuring accuracy. For example, the advanced PID control algorithm can dynamically adjust the motion trajectory according to the real-time feedback position information, ensuring that the positional error of dispensing and patching is always controlled within the permissible range.
High-precision sensors: The equipment is equipped with a variety of high-precision sensors, such as displacement sensors, pressure sensors and so on. Displacement sensors are used to monitor the position of the dispensing head and patch head in real time to ensure that they move according to the preset trajectory; pressure sensors are used to accurately control the pressure of dispensing to ensure that the amount of dispensing is uniform. These sensors will collect the data real-time feedback to the control system to achieve the precise monitoring and adjustment of the operating state of the equipment.
Third, intelligent visual recognition technology
High-resolution vision system: high-speed dispensing mounter is equipped with high-resolution industrial cameras and advanced image processing algorithms, which can quickly and accurately identify the position, shape and size of electronic components. During the placement process, the vision system locates the components in real time to ensure that the placement head can accurately grasp the components and place them in the specified position. For example, by identifying and analyzing component edges and feature points, placement accuracy can be controlled to within ±0.05mm.
Automatic Calibration and Compensation: The vision system also features automatic calibration and compensation. During the operation of the equipment, due to mechanical wear and tear, temperature changes and other factors, it may lead to a decline in the accuracy of dispensing and placement. The vision system can detect these changes in real time and automatically calibrate and compensate the motion parameters through software algorithms to ensure that the equipment always operates with high precision.
Fourth, high-quality consumables and accessories
Dispensing needles and nozzles: the selection of high-quality dispensing needles and nozzles can effectively improve the quality of dispensing and placement. Different types of dispensing needles are suitable for different glue and dispensing process, such as fine needle for precision dispensing, thick needle for large capacity dispensing. And high quality nozzles can ensure stable gripping of electronic components to avoid components falling or shifting during gripping and placement.
Glue and solder paste: Selecting the right glue and solder paste is also the key to achieving efficient and accurate dispensing and placement. High-quality glue has good fluidity and curing properties, to ensure the uniformity and reliability of the dispensing; and high-quality solder paste has good soldering properties, to ensure the stability of the electrical connection between the components and the circuit board after the patch.
Through the synergistic effect of the above aspects, high-speed dispensing mounter realizes efficient and accurate dispensing and placement, which meets the needs of the electronic manufacturing industry for high-precision and high-efficiency production.
