Description
Technical field
The present invention relates to a kind of scrambler, specifically a kind of photoelectric encoder of exporting simultaneously two kinds of code systems.
Background technology
Photoelectric encoder is that signal or data are worked out, are converted to can be in order to the equipment of the signal form of communication, transmission and storage, photoelectric encoder is divided into again two kinds substantially, a kind of is incremental encoder, a kind of is absolute type encoder, they all are that the Moire fringe that cuts by the generation of the light beam between light-emitting component and the receiving element by moving grating and quiet grating relative motion is principle, through subsequent conditioning circuit comparison, amplification, shaping, carry out subsequent conditioning circuit and process the output square-wave signal.
Incremental encoder is a kind of speed and displacement transducer that angular displacement is converted to digital pulse signal, the output code system is exported with binary mode, can not realize Absolute position measurement, can only realize relative position measurement, incremental encoder is divided into again analog signals and digital quantity signal.
Absolute type encoder is except the function that incremental encoder is arranged, can also realize Absolute position measurement, the code system of output is except binary code, can also realize the various code system output such as Gray code, remaining Gray code, vernier code, by measurement range the single-ring absolute type of being divided into and multi-turn absolute type are arranged, individual pen can be measured 0-360 °, and multi-turn can be measured the more angle position of multi-turn.
Want to realize the measurement function of dual mode in the past on equipment, and must use two scramblers, an incremental encoder, an absolute type encoder, so namely increased the free space of equipment, the colleague has also increased the cost of scrambler itself, brings inconvenience to the user.
Summary of the invention
The purpose of this invention is to provide a kind of saving cost, reduce usage space, reduce installation steps and duration, export simultaneously two integral type scramblers of the function of two kinds of code systems.
The object of the present invention is achieved like this, this scrambler comprises main shaft, encoder main body, moving grating seat, decide grating seat, decide grating, six window photoelectric cells, the circuit board of output increment formula signal, the circuit board of output absolute type signal, receive the receiving tube of absolute type signal, metal moves grating, absolute type is decided grating, circuit board, the absolute type luminotron, the first column, connector, the second column, the 3rd column, the absolute type signal output part, incremental signal output terminal and shell, described main shaft is installed on the encoder main body, moving grating seat is installed on the main shaft, the grating seat of deciding of deciding grating for the installation increment type is installed in encoder main body, the six window photoelectric cells that receive incremental signal are welded on the circuit board of output increment formula signal, the circuit board of output increment formula signal is fastened on the encoder main body by the first column, the circuit board of output absolute type signal is fixed on the circuit board of output increment formula signal by connector, the receiving tube that is used for reception absolute type signal is installed in the circuit board of output increment formula signal, the moving grating of metal that is carved with increment type and absolute type window is installed on the moving grating seat, absolute type is decided grating and is fixed on the circuit board by the 3rd column, the circuit board that is used for installation absolute type luminotron is installed in encoder main body by the second column, and the absolute type luminotron is installed on the circuit board.
The present invention has the following advantages and good effect:
1, principal character of the present invention is the function that scrambler of realization is exported two kinds of code systems simultaneously, one group of remaining thunder trellis code of output, realize the function of absolute type encoder, can measure 0-360 ° angular displacement, another group output binary code, the function of realization incremental encoder, can measure rotating speed and the displacement of the lines of measured axis, so both satisfied the request for utilization of equipment, saved again usage space, more saved scrambler self manufacturing cost.
2, structure of the present invention is saved starting material and user installation cost, does not re-use the function that two scramblers go to realize exporting simultaneously two kinds of code systems, has improved work efficiency.
