• Head sensor for mounting machine

Sensors can perform component electrical performance checks, they are like the eyes of the placement machine, always monitor the normal operation of the machine. The more sensors are used, the higher the intelligence level of multifunction placement machine is

• Pressure sensor: in the multi-function placement machine, including the coupling cylinder and the vacuum generator, all have certain requirements for the air pressure. When the pressure is lower than the required pressure of the equipment, the machine can not operate normally. The pressure sensor always monitors the pressure change.
• position sensor: the transmission positioning of the printed board, including the counting of the PCB, the real-time detection of the motion of the patch head and the worktable, the motion of the auxiliary mechanism, etc., all have strict requirements for the position, these positions need to be realized by the position sensor in the form of the current type.
• Image sensor: real-time display of the working state of the placement machine, mainly using CCD image sensor, it can collect the desired image signal, including PCB position, device size, and computer analysis processing, so that the patch head to complete the adjustment and patch work.
• Laser sensor: Laser has been widely used in placement machine, it can help judge the coplanarity of device pins. as the measured device is running to the monitoring position of the laser sensor, the beam emitted by the laser is irradiated to the IC pin and reflected to the laser reader. if the reflected beam back is the same length as the transmitted beam, the device coplanarity is qualified. when different, the reflected light beam becomes longer due to the upswing of the pin. the laser sensor thus recognizes that the device pin is defective.
• Area sensor: when the placement machine is working, in order to operate safely on the patch head, it is usually provided with a sensor in the motion area of the patch head, and the operation space is monitored by photoelectric principle to prevent the damage caused by foreign objects.
