Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Embodiment 1：As shown in Figures 1 to 3, goal of the invention of the invention is to overcome using easy caused by photo-electronic directly reading mode
By ambient light conditions influenceed or tongue tube sensing reading mode caused by installation process tongue tube it is easily rupturable the problem of, using one kind
The angle rotated by measuring character wheel obtains the direct access mode of character wheel reading：The problem of existing for prior art, there is provided a kind of.
To achieve these goals, the technical solution adopted by the present invention is：A kind of magnetic strength character wheel for character wheel counter,
Including,
Character wheel body 1, the prominent tooth of a circle stepping is evenly equipped with the circumferential edges of a side of the character wheel body 1；Institute
State the prominent tooth 4 of stepping and for receiving outside transmission power the character wheel is rotated；Dashed forward at the circumferential edges of opposite side provided with carry
Tooth 5,0~90 digit positions are divided on the circumference side of character wheel body 1, i.e., each digit position takes character wheel circle
All 36 degree of radian sizes, each position can select to show label or not show label, not show that label refers to, only determine to divide equally
Ten positions in one be 0 after, choose to install direction order according to character wheel and determine each digit position, but numeral is not labeled in
On character wheel.
Character wheel axis body 2, it is arranged on the circle centre position of character wheel body 1 and, the character wheel axis body vertical with the character wheel body 1
2 length are more than the thickness of the character wheel body 1 and stretched out to the both sides of character wheel body 1；
Circular magnetic steel 3, it is embedded in the side of character wheel body 1 and coaxial with the character wheel body 1.The annular magnetic
Steel 3 is to be fixedly connected with the character wheel body, therefore can just be rotated with the character wheel.
Further, the circular magnetic steel 3 is bipolarity radial magnetizing ring alnico.
The diameter of section of circular magnetic steel 3 is 9.02mm to 9.06mm.
During actual use, the character wheel is placed on support frame as shown in Figure 4 by character wheel axis body 2（Support frame as described above
Including base 63, support frame 1 and support frame 2 62；It is provided with support frame as described above 1 and support frame 2 62 and the word
The semi-circular recesses 611,621 that wheel axis body 2 size, shape are agreed with.The character wheel by by the character wheel axis body 2 in the semicircle
Connected in star 611,621 internal rotations）, the character wheel receives rotatory force by the prominent tooth of the stepping and rotated, any one in the character wheel
Side be arranged in parallel angle detection device, such as angular transducer（Also known as magnetic coder, such as chip MMA253F）, when the character wheel turns
When dynamic, the circular magnetic steel 3 rotates with the character wheel, and the angular transducer becomes according to the magnetic field of the circular magnetic steel 3
Change and obtain the angle that the character wheel rotates, so as to obtain the current reading of the character wheel；Because angular transducer is to annular magnetic
The angle sensing sensitivity of steel 3 is high, can measure the rotation of the circular magnetic steel 3 once in theory, and actually character wheel
Upper ten numerals are corresponding 36 degree of radians, therefore use character wheel provided by the invention, can provide precision higher measurement knot
Fruit.
In some specific embodiments, install for convenience, the angular transducer is arranged on collection plate, the collection plate
Processor can be plugged into（It is responsible for the angle that each character wheel rotates being scaled numeral and output display）On the circuit board at place.
Generally all it is by the way of character wheel group in actual use（Also can the exclusive use of individual character wheel）Character wheel is counted
Number, therefore magnetic shielding cover is set generally between character wheel and character wheel, to prevent the magnetic force between different character wheels from interfering with each other, now
With the carry gear coordinate and carry out carry transmission by the prominent tooth of the carry, the prominent tooth of stepping between adjacent character wheel.
Identical with the character wheel in most prior art, character wheel described in the present embodiment is in addition to the annular magnetic steel 3
Part is made by not possessing ferromagnetic material, e.g., can be but not limited to plastics.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
