Description
Technical field
This utility model relates to a kind of encoder.
Background technology
Multi-turn absolute value encoder enables to the measurement scope of individual pen absolute value encoder and strengthens so that the function measuring individual pen position of rotation extends to measure rectilinear movement distance.The number of turns counting mode of encoder is various, mainly has gear structure counting structure, Hall chip counting and magnetoresistive chip counting etc..Owing to gear structure, while adding encoder own wt, the accuracy of counting also depends on gear part and the corresponding machining accuracy separating code-disc, and the labyrinth that gear structure brings also brings product reliability risk.Hall chip also has stability characteristic (quality) bad, and application does not have the shortcomings such as universality.Respective magnets design complexity, magnetoresistance device can only export analogue signal, can increase subsequent process circuit, causes circuit complexity to increase.
Summary of the invention
This utility model provides a kind of encoder using tongue tube, and complicated with the structure solving presently, there are, stability characteristic (quality) is bad, the problem of poor reliability.
This utility model adopts the technical scheme that: install two bearings in encoder main body, bearing outer ring is connected with main body, bearing inner race is connected with encoder axle, code-disc is arranged on encoder axle, pcb board is installed in main body, Magnet is arranged on encoder axle, sentences and is positioned at the pcb board bottom above magnet to counting module, and individual pen data processing unit lays respectively on pcb board with counting processing unit.
Described sentence include that this tongue tube is according to radially or tangentially arranging for 1,2 or 3 tongue tubes detecting magnetic field of magnets to counting module.
Described tongue tube is outside is wound around coil.
Described sentencing when counting module includes 1 tongue tube, corresponding Magnet is square；
Described sentencing when counting module includes 2 tongue tubes, in 90 ° of arrangements between these 2 tongue tubes, corresponding Magnet is semicircular arc；
Described sentencing when counting module includes 3 tongue tubes, in 90 ° of arrangements between two tongue tubes therein, corresponding Magnet is semicircular arc, and the Magnet that another tongue tube is corresponding is square.
The utility model has the advantages that novel structure, utilize tongue tube to realize encoder and sentence the method to counting, 1,2 or 3 tongue tube is used to realize encoder rotating cycle tally function, the changes of magnetic field that tongue tube detection rotates with encoder axle, closure state is opened in switching, thus switching on and off subsequent counter circuit, thus calculation code device rotating cycle, in order to extend tongue tube service life, coil can be wound around in outside, enormously simplify the structure of encoder.

Detailed description of the invention
Two bearings 2 are installed in encoder main body 1, bearing outer ring is connected with main body, bearing inner race is connected with encoder axle 3, code-disc 4 is arranged on encoder axle, pcb board 5 is installed in main body, Magnet 6 is arranged on encoder axle 3, sentences and is positioned at the pcb board bottom above magnet to counting module 7, and individual pen data processing unit 8 lays respectively on pcb board with counting processing unit 9；
Described sentence include that this tongue tube is according to radially or tangentially arranging for 1,2 or 3 tongue tubes 701 detecting magnetic field of magnets to counting module 7；
Described tongue tube 701 is outside is wound around coil 702；
Described sentencing when counting module 7 includes 1 tongue tube, corresponding Magnet is square, as shown in Fig. 2 a, 3a, 4a；
Described sentencing when counting module 7 includes 2 tongue tubes, in 90 ° of arrangements between these 2 tongue tubes, corresponding Magnet is semicircular arc, as shown in Fig. 2 b, 3b, 4b；
Described sentencing when counting module 7 includes 3 tongue tubes, in 90 ° of arrangements between two tongue tubes therein, corresponding Magnet is semicircular arc, and the Magnet that another tongue tube is corresponding is square, as shown in Fig. 2 c, 3c, 4c；
When using a tongue tube, under absolute value optical system, often enclose voltage output once, realize multi-turn counting, the increase and decrease of the basis for estimation absolute value data turned to, that is to say, when a tongue tube has output, now next absolute position values is big compared with previous absolute value, is main story and adds 1 circle, on the contrary the circle that subtracts 1；Triggering with tongue tube square wave rising edge, store current absolute location value, continuous cycle detection current absolute value and next absolute value, outbound course information, until running into next trailing edge, flip-flop number carries out adding or the counting that subtracts 1.
When using two tongue tubes, under optical system output individual pen absolute value data, the often square-wave signal of two phase 90 of circle output, realize multi-turn counting, the different output logical state combination of the tongue tube signal according to two phase 90 degree differentiate encoder direction of rotation, thus number of turns data are added and subtracted, wherein a tongue tube is as number of turns count signal.
When using three tongue tubes, under optical system output individual pen absolute value data, 90 ° of square-wave signals of phase are exported by two of which, 3rd realizes multi-turn counting, the defeated roller of difference of the tongue tube signal according to two phase 90 degree goes out logical state combination and differentiates encoder direction of rotation, thus adds and subtracts number of turns data.
