The placement machine is a high-precision industrial loading and unloading device. It is a part of many important equipment. Its positioning system is the main indicator for evaluating the accuracy of the placement machine. It is driven by the AC servo motor and is commanded by the sensor and control system. Accurate positioning is achieved, so the accuracy of the sensor plays a key role. The displacement sensor has a circular encoder, a magnetic scale and a grating scale. The placement machine is plated with bright and dark radial chrome lines. The adjacent light-dark spacing is called a grid. The total number of square-sections is the number of line pulses of the encoder.

The placement machine is a high-precision industrial loading and unloading device. It is a part of many important equipment.

The placement machine is plated with bright and dark radial chrome lines. The adjacent light-dark spacing is called a grid. The total number of square-sections is the number of line pulses of the encoder.
The placement machine has a square wave or sine wave magnetic trajectory signal of a certain wavelength after a certain year. The magnetic head moves and reads the magnetic yoke on the magnetic scale, and is converted into an electrical signal input to the control circuit to finally control the operation of the AC servo motor. The advantages of the magnetic scale are simple manufacturing, convenient installation, high stability, large measuring range, measurement accuracy of up to 1~5um, and patching accuracy of generally 0.02mm. This kind of measurement is to be best after tens of millions of ways. Shenzhen Jinshiwang Technology Co., Ltd. has developed such a technology and used it. In two years, it came to an effective principle and definition. The accuracy is one to two orders of magnitude higher than the magnetic scale.
When the turret structure is in motion, the placement speed is limited due to the limited maximum allowable radial acceleration on the vacuum nozzle. Nozzle
According to the calculation of mechanical motion engineering mechanics, the maximum allowable acceleration between the device and the nozzle is not more than 50 m/s2. So you need high placement
There are 3 time-determining cycles for the turret time. So, if you want a placement machine, you can contact us. For details, please enter Shenzhen Weida Electronic Equipment Co., Ltd.
