Description
Technical field
The present invention relates to a kind of device of the accurate location of photoelectric tube on the instrument code-wheel.
Background technology
In recent years, owing to developing rapidly of integrated circuit technique, electronic counting and positioning system are used more and more widely in scientific instrument, and its integrated level is also more and more higher, and electron device is also more and more small.The infrared ray photoelectricity of the miniwatt small size that having used in electric filter light modulation apparatus does not keep in dark place disturbs selects for use this infrared ray photoelectricity to the benefit of pipe to be to the pipe location of encoding, and can weed out shining the light reaction signal that causes by parasitic light.Adopted three groups of infrared ray photoelectricity to pipe in electric filter light modulation apparatus, every group of infrared ray photoelectricity is to managing the both sides that all are distributed in code-wheel, and code-wheel rotates during work, and infrared ray photoelectricity is motionless to managing.Because infrared ray photoelectricity is a kind of miniwatt luminotron to pipe, and each infrared ray photoelectricity minor diameter has only 1.5mm to managing very, if the relative infrared ray photoelectricity of the aperture of code-wheel departs from 0.5mm slightly to pipe during debugging, the photoimpact that sends of each infrared light emission pipe just can accurately not delivered on the infrared receiver tube so, just there is the spike pulse of many shakes at the photoimpact waveform edge that infrared receiver tube is received, and little many of the pulse amplitude of pulse amplitude during than alignment hole, under this condition, control circuit can produce error message when its shaping is handled, interpretation to system plays the serious disturbance effect, and is difficult for eliminating.With the tri-bit encoding dish is example; In electric filter light modulation apparatus, adopted three groups of infrared ray photoelectricity to pipe, can seven gears on the code-wheel be positioned, use the oscillograph debugging that three probes will be installed by classic method so, and on seven gears, debug three groups of infrared ray photoelectricity repeatedly to pipe, the aperture of its code-wheel is overlapped substantially with each infrared light emission pipe, receiving tube in the printed board, at this moment on oscillograph, just can see the photoelectric pulse signal that pulse amplitude is more or less the same.By that analogy, if adopted four groups, five groups infrared light emissions to pipe in the work, the workload when debugging so is just very big, very low of efficient.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of accurate locating device of photoelectric tube is provided, not only can improve the work efficiency of scientific research personnel in producing debugging, shorten the debug time of photoelectric tube on the code-wheel; But also can save expensive oscillograph, and reduced cost, satisfied the high-level efficiency requirement of modern science development.
The present invention solves the solution that its technical matters adopts: the locating device of photoelectric tube on the code-wheel, wherein the code-wheel symmetria bilateralis is distributed with infrared electro receiving tube and infrared electro luminotron, the infrared electro receiving tube is welded on the receiving tube circuit board, the infrared electro luminotron is welded on the luminotron circuit board, receiving tube circuit board and luminotron circuit board are fixed on the supporting seat, organize aperture by the scale-of-two layout on the code-wheel more; It is characterized in that: on receiving tube circuit board and luminotron circuit board, be the axle center, with respect to infrared electro pipe rotated 10 °～20 ° and make two pilot holes with the center of code-wheel;
The size and location of described two pilot holes can overlap with a certain group of non-conterminous aperture on the code-wheel; When debugging, slightly be installed to luminotron circuit board and receiver pope circuit board on the assigned address, rotate code-wheel, two pilot holes are overlapped with described a certain group of non-conterminous aperture on the code-wheel, receiving tube circuit board and luminotron circuit board and code-wheel are fixed together by two pilot holes with two register pins, again luminotron circuit board and receiving tube circuit board are fixed on the supporting seat, extract two register pins then out, finish accurate location.The figure place of described code-wheel is more than or equal to 3.
Have of the figure place decision of the group number of aperture on the described code-wheel by code-wheel.
Described infrared electro receiving tube is identical by the figure place of code-wheel with the logarithm of infrared electro luminotron.
The present invention has following advantage compared with prior art:
The accurate locating device of photoelectric tube on the code-wheel of the present invention, need locate on a certain group of non-conterminous aperture position on the code-wheel, just can guarantee the binary coding aperture inregister on infrared electro luminotron, infrared electro receiving tube and the code-wheel, avoided the work of using oscillograph to debug repeatedly, improved work efficiency greatly and reduced cost; This locating device is applicable to the tri-bit encoding dish, also can be used on four, five, even more on the code-wheel of long number.
