Okplazas.com encoder introduces to you: What are the maintenance methods of photoelectric pulse encoder?

The photoelectric pulse encoder is a machine tool installed at equal intervals on the edge of the disc. Both ends of the machine tool are equipped with light sources and photosensitive elements. When the disc is changed, the brightness of the light changes. After the photosensitive element detects the intensity of the electrical signal, a pulse signal is obtained. The output signal of the encoder includes: two-phase signal output, used for direction recognition; a zero signal (also called steering signal), used to control the machine tool to return to the reference point; the other is the 5V power supply and ground terminal.

The protection and maintenance of the encoder should pay attention to the following issues:

1. The shock-proof and dirt-proof encoder is an excellent measuring element with good self-sealing. When using and disassembling, it should be the same as the grating ruler, and pay attention to shock and pollution prevention. Only pollution will occur at the lead-out section and the plug connection, and protective measures should be taken for these parts. The machine vibration is simple, and the external fasteners loosen and fall off, causing an external short circuit.

Second, the problem of convergence is divided into loose convergence and improper convergence adjustment. The connection mode of the encoder has external connection and internal connection. When the transmission chain is long, the device can reduce the influence of the cumulative error of the transmission chain on the accuracy of the azimuth angle detection.

Due to the loose connection of the machine tool, the accuracy of the azimuth control is often affected. In some communication servo motors, in addition to bearing detection, the built-in encoder also has the function of speed measurement and rotor position detection. Therefore, the loose connection of the encoder will cause unstable feed movement, affect the commutation control of the communication servo motor, and cause machine tool vibration. In addition, the encoder is connected by a belt drive. If the transmission belt is adjusted too tightly, if the force is too large, the encoder bearing will only be damaged.
