The utility model content
At the deficiencies in the prior art, the purpose of this utility model is the rotating disk positioning system that a kind of simple in structure, accurate positioning will be provided.
For this reason, the utility model provides a kind of rotating disk positioning system, comprise photoelectric sensor, rotating disk, stepper motor, single-chip microcomputer and power supply, rotating disk is installed in the rotating shaft of stepper motor, the below of rotating disk is provided with photoelectric sensor, be connected with the Stepping Motor Control signal input part behind the control signal output ends series connection single-chip microcomputer of photoelectric sensor, photoelectric sensor also connects power supply, the lower surface of rotating disk is equipped with reflecting plate, in the dial rotation process, reflecting plate can be driven photoelectric sensor directly over; Photoelectric sensor is a retro-reflection optoelectronic sensor, and light signal transmitting terminal and light signal receiving end all are arranged at the upper surface of photoelectric sensor.Reflecting plate is installed on disk lower surface, and its reflection action is not subjected to the interference of other instruments that rotating disk places above, and system stability is good.Retro-reflection optoelectronic sensor has simple in structure, highly sensitive advantage.
According to an aspect of the present utility model, the upper surface of photoelectric sensor is parallel with the lower surface of reflecting plate, makes reflecting plate the light signal of photoelectric sensor emission can be transmitted into fully the receiving end of photoelectric sensor, reduces energy loss.
According to another aspect of the present utility model, the vertical range between the upper surface of photoelectric sensor and the lower surface of reflecting plate is 10mm.External interference may be decayed and be subjected to the consideration light signal in communication process, select 10mm as suitable operating distance.
According to another aspect of the present utility model, power supply is a direct supply, and this direct supply provides reliable and stable driving power for the rotating disk positioning system.
Compared with prior art, the beneficial effects of the utility model are: this rotating disk positioning system is installed on the lower surface of rotating disk with reflecting plate, makes the light reflection avoid being subjected to the influence of other instruments of placing the rotating disk top, the bearing accuracy height, and error is little.Distance between reflecting plate and the photoelectric sensor is very little, makes the system response sensitivity, and is not vulnerable to external interference.In addition, native system also has advantages such as simple in structure, easy for installation.
Description of drawings
Above-mentioned and/or additional aspect of the utility model and advantage are from obviously and easily understanding becoming the description of embodiment below in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation of rotating disk positioning system of the present utility model.
Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar device or the device with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the utility model, and can not be interpreted as restriction of the present utility model.
Shown in Fig. 1 is the structure of rotating disk positioning system of the present utility model.This rotating disk positioning system comprises photoelectric sensor 1, rotating disk 3, stepper motor 4, single-chip microcomputer 5 and power supply 6, rotating disk 3 is installed in the rotating shaft of stepper motor 4, the below of rotating disk 3 is provided with photoelectric sensor 1, control signal output ends series connection single-chip microcomputer 5 backs of photoelectric sensor 1 are connected with the signal input end of stepper motor 4, photoelectric sensor 1 also connects power supply 6, the lower surface of rotating disk 3 is equipped with reflecting plate 2, in rotating disk 3 rotation processes, reflecting plate 2 can be driven photoelectric sensor 1 directly over.Reflecting plate 2 is installed on rotating disk 3 lower surfaces, and its reflection action is not subjected to the interference of other instruments that rotating disk places above, and system stability is good.Photoelectric sensor 1 is a retro-reflection optoelectronic sensor, and light signal transmitting terminal and light signal receiving end all are arranged at the upper surface of photoelectric sensor 1.This class photoelectric sensor has simple in structure, highly sensitive advantage.
The upper surface of photoelectric sensor 1 is parallel with the lower surface of reflecting plate 2, makes reflecting plate 2 light signal of photoelectric sensor 1 emission can be transmitted into fully the receiving end of photoelectric sensor 1, reduces energy loss.
Vertical range between the lower surface of the upper surface of photoelectric sensor 1 and reflecting plate 2 can be set to 10mm.External interference may be decayed and be subjected to the consideration light signal in communication process, select 10mm as suitable operating distance, can guarantee that the light reflection paths is short and avoid external interference, has short, highly sensitive advantage of reaction time.
Single-chip microcomputer 5 can adopt the 89S51 series monolithic, and power supply 6 is a direct supply, and this direct supply provides reliable and stable driving power for the rotating disk positioning system.Because the operating voltage of single-chip microcomputer 5 is 5V, stepper motor 4 needs the driving power of 24V, and power supply 6 general 0~30V direct supplys that adopt get final product.
In the course of work of this rotating disk positioning system, after power supply 6 is connected, the optoelectronic switch of photoelectric sensor 1 places normally open, its light signal transmitting terminal is upwards launched light, this moment, the light signal receiving end was not received the light of reflected back as yet, rotating disk 3 begins to rotate under the drive of stepper motor 4 simultaneously, together rotates thereby drive reflecting plate 2.When reflecting plate 2 turn to photoelectric sensor 1 directly over the time, the receiving end of photoelectric sensor 1 can receive the light that reflecting plate 2 reflects, the triggering optoelectronic switch cuts out, thereby produces a control signal, and is transferred to single-chip microcomputer 5 by control signal output ends.Single-chip microcomputer 5 generates the signal input end that is transferred to stepper motor 4 after control instruction corresponding according to this control signal and stops operating with order stepper motor 4, thus the location of realizing rotating disk 3.
In this process, photoelectric sensor 1 does not directly contact with rotating disk 3, but by the optical signal transmission positional information, because the vertical range between photoelectric sensor 1 and the reflecting plate 2 is very little, the time that reflecting plate 2 reflexes to photoelectric sensor 1 to light, the reaction time lacked less than 3ms, good reliability, rotating disk 3 is reduced because of the positioning error that time-delay produces, and this distance can be avoided the interference of extraneous other light sources as far as possible simultaneously, reduces maloperation.This rotating disk positioning system is simple in structure, easy for installation, volume is little, and adopts highly sensitive photoelectric sensor, and system reliability is very high.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
