The mechanical arm movement spacing principle circuit

Published:2011/6/11 21:49:00 Author:qqtang | Keyword: mechanical arm, movement spacing

To make sure the mechanical catches and put workpieces in the right place, we often use the approaching sensor to limit its moving range. In the figure is the control diagram of the mechanical left/right movement spacing. The sensor is located in the place where the mechanical arm needs spacing, when the mechanical are moves left/right and gets close to the sensor, the sensor will output the control signal if it detects that the mechanical arm is approaching and reaches the regulated range, and the mechanical arm is stopped by the executing sector.

The circuit of IC oscillating circuit-inductance three-point oscillator

Published:2011/6/13 21:49:00 Author:Seven | Keyword: IC oscillating circuit, inductance three-point oscillator

(1) the formation of inductance three-point oscillatorIn figure 1 is the principle diagram of the inductance three-point oscillator circuit. Seeing from the circuit, we know that the inductor of LC parallel resonance circuit has a front-end point, a middle point and a tail point, whose AC circuit connects with the collector electrode of the amplifier circuit, emitter(ground) and basic pole respectively, the feedback signal is from the voltage on the inductor L2, therefore, we conventionally call the circuit in Figure 1 the inductance three-point LC oscillating circuit, or the inductance feedback oscillating circuit.   (View)
