Mounter is a high precision industrial unloading equipment, is a lot of important equipment parts, and its positioning system is the main indicator of the accuracy of the placement machine, which is driven by the AC servo motor, and in the sensor and control system command To achieve precise positioning, so the accuracy of the sensor play a key role. Displacement sensors have garden grating encoders, magnetometers and gratings. The patch chip is coated with a light and dark radiating chrome line, and the adjacent light and dark pitch is called a gate section. The total number of gate sections is the number of pulse pulses of the encoder.

Mounter after a certain year after a certain wavelength of the square wave or sine wave magnetic track signal. The magnetic head moves on the magnetic scale and reads the magnetic flux, and converts it into an electrical signal input to the control circuit, and finally controls the operation of the AC servo motor. The advantages of magnetic scale is simple manufacturing, easy installation, high stability, range range, measurement accuracy of up to 1 ~ 5um, patch accuracy is generally 0.02mm. This measurement is to go through tens of millions of times in order to do the best, Shenzhen Golden Lion King Technology Co., Ltd. R & D of such technology used a full two years to come up with a valid principle and definition of its positioning Accuracy than the magnetic scale even higher 1 to 2 orders of magnitude.
