The role of seven sensors of the SMT machine

NeoDen K1830 PNP machine

Sensor is an important induction instrument in the processing and production of SMT machine. It plays an important role in SMT production line.

1. Mount head sensor: with the increase of SMT mount head speed and accuracy, mounting head placed on the substrate components of the intelligent requirements are more and more high.
2. Laser sensor: laser has been widely used in the pick and place machine, it can help identify the co-planarity of the device pins, laser sensor can also identify the height of the device, thus shortening the production preparation time.
3. Area sensor: In order to operate safely during the processing of the mount machine, sensors are usually set in the moving area of the patch head to monitor the operating space by photoelectric principle and prevent foreign body damage.
4. Negative pressure sensor: SMT mount machine in the processing, chip head suction nozzle through the negative pressure suction components. It consists of a negative pressure generator and a vacuum sensor. When the negative pressure is insufficient, the components will not be absorbed.
5. Position sensor: the transmission and positioning of the substrate, including the substrate count, the mounting head position of the mount machine and the real-time monitoring of the work table, all have strict requirements on the position. These position requirements are achieved through various forms of position sensors.
6. Image sensor: real-time display of the working state of the mount machine, mainly, can collect the required various image signals, including the position of the substrate, the size of components, etc., after computer analysis and processing, the mount head of the mount machine to complete the adjustment and positioning work.
7. Pressure sensor: the pressure system of the mount machine includes various working pressures and vacuum generators. These generators have a certain pressure requirement. Pressure sensors always monitor pressure changes. Once the SMT machine is abnormal, it will alarm and remind the operator to handle it.
