The Mirae pick and place machine manufacturer tells you that the component feeder and substrate (PCB) of the arch-type placement machine are fixed, and the placement head (with multiple vacuum suction nozzles) moves back and forth between the feeder and the The components are taken out from the feeder, and the position and orientation of the components are adjusted, and then placed on the substrate. Because the placement head is installed on the X/Y coordinate moving beam of the arch type, it is named.

The adjustment method of the component position and direction of the arch-type placement machine:
1) The manufacturer of Mirae pick and place machine tells you that the position of the machine is adjusted for centering and the direction of rotation of the suction nozzle is adjusted. The accuracy that this method can achieve is limited, and the later models are no longer used. 2), laser identification, X/Y coordinate system adjustment position, nozzle rotation adjustment direction, this method can realize the identification during flight, but cannot be used for ball grid display element BGA.
3), Mirae pick and place machine manufacturers tell you that camera identification, X/Y coordinate system adjustment position, nozzle rotation adjustment direction, generally the camera is fixed, the patch head flies over the camera to perform imaging identification, which is a little longer than laser identification time, but can identify any element, there are also camera identification systems that enable identification during flight, and there are other sacrifices in terms of mechanical structure.
Mirae pick and place machine manufacturers tell you that this form is limited in speed due to the long distance that the placement head moves back and forth. Generally, multiple vacuum suction nozzles are used to take materials at the same time (up to ten) and a double-beam system is used to increase the speed, that is, the patch head on one beam is reclaiming the material, and the patch head on the other beam places the components. , almost twice as fast as the single beam system. However, in practical applications, it is difficult to achieve the condition of taking materials at the same time, and different types of components need to be replaced with different vacuum suction nozzles, and there is a time delay in changing the suction nozzles.
Mirae pick and place machine manufacturers tell you that the advantages of this type of machine are: the system has a simple structure, can achieve high precision, and is suitable for components of various sizes and shapes, even special-shaped components. . It is suitable for small and medium batch production, and can also be combined with multiple machines for mass production.
The above information is Mirae pick and place machine manufacturer's introduction and analysis of the arch type placement machine, hope it helps you.
