In order to improve production efficiency and shorten working time, the new pick and place machine is moving towards a highly efficient two-way conveying structure. Based on the performance of the traditional single pick and place machine, the two-way conveyor pick and place machine designs the PCB, positioning, detection, and placement into a two-way structure. The working mode of the two-way structure placement machine can be divided into synchronous mode and asynchronous mode.
The synchronous method is to synchronously send two PCBs of the same size to the installation area for installation, while in asynchronous mode, it sends PCBs of different sizes to the installation area respectively. Both of these two working methods can shorten the ineffective working time of the pick and place machine and improve the production efficiency of the machine.
The installation speed, accuracy and placement function of the pick and place machine have always been contradictory. The manufacturers of new pick and place machine have been working hard to achieve high speed, high precision, and multi-function. Due to the continuous development of surface mount components (SMC/SMD), packaging forms continue to change. New packages such as BGA, FC, and CSP place higher requirements on pick and place machines.
In traditional pick and place machine, there is only one cantilever and placement head, which cannot meet the speed requirements of modern production. For this reason, a dual-cantilever pick and place machine based on the single-cantilever pick and place machine have been developed. Two placement heads are alternately connected to the same PCB. When the occupied area of machine changes little, the production efficiency is doubled.
In order to further improve production efficiency, four-cantilever pick and place machines have been introduced on the basis of double-cantilever machines. The multi-cantilever machine has replaced the position of the turret machine and has become the mainstream trend of the development of high-speed pick and place machines in the future.
