Common high-speed packaging lines for temperature and pressure sensors include fully automatic placement machine bodies, fully automatic gold wire bonding machines, and gel vacuum sealing machines. The placement head inside the existing fully automatic placement machine body is an intelligent manipulator, which also becomes a cantilever in the placement machine body. A placement head has multiple nozzles to pick up the required components and accurately shift and place them on the circuit board pads. Component picking generally adopts a vacuum negative pressure nozzle to suck the component. When the nozzle moves, it must not only pick up quickly but also be stable and accurate. The nozzle is responsible for picking up the specified components through the motor and camera recognition control system loaded on the placement head through programming. However, the head of most high-speed placement machine bodies can be installed at full speed when picking up and installing small components, but when picking up and installing larger or more components, a certain degree of placement machine body accuracy and some functions are usually sacrificed to achieve high-speed placement, resulting in most of the current fully automatic placement machine bodies have high speed but low accuracy, or the speed is difficult to meet the requirements.
