Description
Technical field
The utility model discloses a kind of sensor, a kind of specifically noncontact magnetoelectricity rotary encoder, this scrambler can be widely used in fields such as numerically-controlled machine, elevator industry, navigation, robotization, aviation, Electric Machine Control and industrial automation.
Background technology
Scrambler is a kind of rotating detector that angle displacement is converted to a succession of digit pulse.Its basic structure is made up of luminescent device, code-disc, slit, receiving element.When the scrambler axle drove the code-disc rotation, the light that sends through light-emitting component was cut into interrupted light by code-disc, slit and is received element and receives, and produces initialize signal, this signal after subsequent conditioning circuit is handled, output signal.The precision of rotary encoder depends on machinery and electric factor, and these factors have: the inexactness of optical disc eccentricity, bearing off-centre and opticator.Traditional photoelectric encoder is because its code-disc is generally glassware, and is frangible, has inborn shortcoming aspect anti-vibration, and degree of protection is low, and operating temperature range is narrow, and-20
0C is to+50
0C, and code-disc when delineation accuracy requirement height, difficulty is big.The assembly cost height, production efficiency is low.Need main shaft and bearing on the structure, the purchase cost height.During assembly and adjustment for bearing, main shaft, main body, the cooperation between the optical device etc. is strict, difficulty is big reducing on the error, production efficiency is low.
Summary of the invention
The purpose of this utility model is to adopt the magnetoelectricity principle, solve that traditional photoelectric encoder code-disc is frangible, accuracy requirement is high, complicated in mechanical structure, debug shortcomings such as process is loaded down with trivial details, select for use the magnetoelectricity integrated chip to realize the generation of signal, receive and handle, save the debug process of traditional photo-electric complexity, increase substantially the performance of production efficiency and product, the noncontact magnetoelectricity rotary encoder that a kind of microminiaturization, reliability height, anti-vibration, high frequency sound, low cost, precision height, error are little, the life-span is long is provided.
The purpose of this utility model is to realize like this, this scrambler comprises scrambler main body I and spindle nose II, and described scrambler main body I comprises the loam cake and the lower cover that constitute main body cover, be arranged on wiring board in the main body cover, magnetic induction chip in the circuit board is set; Described spindle nose II comprises the spindle nose main body that connects client's use side, is arranged on the magnetic post on the spindle nose main body.
The utility model is owing to adopt said structure to have the following advantages:
1, the utility model scrambler need not code-disc, slit, luminous and receiving element, bearing, has simplified physical construction greatly, has also reduced purchase cost simultaneously.Adopted the noncontact design, precision height, life-span are long.Selected high-precision magnetic sensing chip on the circuit board in scrambler main body I for use, adopt the magneto-electric principle, can discern the angle position of the magnetic post that is positioned at spindle nose, in have integrated circuit that it is handled, can enroll different programs as required, realize different umber of pulses and phase relation, be that circuit is simple, weight is little, uses lighter.
2, the utility model has solved that traditional photoelectric encoder code-disc is frangible, accuracy requirement is high, and complicated in mechanical structure is debug shortcomings such as process complexity.Select for use the magnetoelectricity integrated chip to carry out the generation of signal, receive and handle, saved the debug process of traditional photo-electric complexity, have remarkable advantages, increase substantially production efficiency, have advantages such as microminiaturization, high reliability, anti-vibration, high frequency sound, the high and low cost of precision.
3, physical construction is simplified firm: need not code-disc and bearing, can be directly the spindle nose that has the magnetic induction chip be installed in survey on the object, measure, dirigibility is strong.Circuit board is in sealing state in main body, the degree of protection height can be grease proofing, waterproof, dust protection etc., and operating temperature range is wide, and-40
0C is to+125
0C.IP64 can be reached, high strength bump and vibrations can be resisted.
