The LED pick and place machine is a kind of equipment used in the LED industry. It belongs to the SMT (Surface Mount System) placement machine, which can be used to assemble a large number of LED circuit boards. Do you know how the LED pick and place machine adjusts the position and direction of the components?
LED pick and place machine placement: its batch is large. Moreover, its supply cycle is tight, and the working procedures are complicated, so it is suitable for mass production.
Manual placement: It is easy to operate. In addition, its cost is relatively low. However, its production efficiency depends on the proficiency of the operating personnel.
The main tools for manual placement: vacuum suction pen, tweezers, IC suction and placement aligner, low-power stereo microscope or magnifying glass and so on.
The method of adjusting the position and direction of components for LED pick and place machine:
1. Adjust the position of the LED pick and place machine and adjust the direction of the nozzle rotation. The accuracy of this method is limited, and it is no longer used in later models.
2. Laser recognition, X/Y coordinate system adjustment position, nozzle rotation adjustment direction, this method can realize the recognition during the flight, but it cannot be used for the ball grid array element BGA.
3. Use the camera to identify, use the X/Y coordinate system to adjust the position, and use the nozzle to rotate to adjust the direction. Generally, the camera is fixed, and the placement head flies over the camera to perform imaging recognition. A camera recognition system that realizes recognition during flight can recognize any component.
The advantages of this type of LED pick and place machine are: its system structure is simple, and it can achieve high precision. It is suitable for components of various sizes and shapes, and even special-shaped components. The feeder has the form of belt, tube and tray. It is not only suitable for small and medium batch production, but also multiple machines can be combined for mass production.
