A magnetic pole distance of the reference signal magnetic area is different from an original main magnetic area magnetic pole distance on the magnetized tape, a magnetic field signal source for detecting different periods of components can be provided, and the magnetic field signal source is used as an origin point, a limit point or similar position of a relevant reference position. The technology for forming the reference signal magnetic area is that secondary magnetizing is conducted on a certain position selected on the magnetized tape through magnetizing pieces such as a magnet so as to change the magnetic pole distance of one portion of each original main magnetic area on the magnetic tape, and the reference signal magnetic area is formed.
Description
Technical field
The present invention is relevant with the technology of carrying out linear position measurement with changes of magnetic field, particularly a kind of job operation with the tape of reference by location signal magnetic region.
Background technology
The Magnetic ruler technology that the technology utilizing positional increment and changes of magnetic field to sense carries out linear position measurement is widely used in position and measures on applicator platform, and in order to provide the tape of changes of magnetic field, generally speaking, it extends continuously on the rectangular belt body of suitable length one, establish different magnetic pole in the side of belt body on the surface sequentially, accordingly, when sensing element is along the long axis direction displacement action of this belt body, the change in magnetic field is sensed with the change of position, but because it must provide the changes of magnetic field of rule, therefore, pole pitch on this tape is definite value, suitable sensing reference point cannot be provided as the reference signal of position to cause this tape, be used as origin position, extreme position or other similar positions.
For improving the deficiency of above-mentioned conventional art, in located by prior art, there is technology contents to be as shown in Figure 1 disclosed, specifically, the optical signal district of its Formation rule on a belt body 1 extended continuously, corresponding signal is obtained by the reading of optical signal, and independently magnet device 2 is arranged at the side of this belt body 1, to form the magnetic region providing reference position signal; Or have technology contents as shown in Figure 2, on tape 3 same surface with rule changes of magnetic field, form the position signal district 6 of a continuous equidistant arrangement, and the reference signal district 7 of discontinuous equidistant arrangement, and make each position signal district have identical magnet pole widths with reference signal district, reach the object providing sensing element to sense; Accordingly, provide the signal source of a reference position by this reference signal magnetic region, using the location as such as origin position, extreme position or other similar position.
Although above-mentioned known techniques reaches the effect of the correction reference point providing reference signal, its technology is still undesirable, specifically:
In the known techniques of extra additional magnet, it must pass through extra magnet device of installing and provides independently magnetic field, and sensing element is responded to, and not convenient on arranging, also shortcoming can answer actual demand to make flexible effect of different change;
And made tape after sense magnetic program is carried out by barrier flaps, the position signal district and reference signal district with same pole width is able to form in respectively on same surface, thus by the difference on locus, make it to provide the signal source that two kinds different, but, because it need while carrying out giving tape rule magnetic region, form locus by barrier flaps and have other reference signal district, therefore, it only can carry out in the manufacture end of tape, and cannot at the use side of tape by user voluntarily because actual demand sets the reference point of reference position, similarly, also the effect of answering flexibly needed for reality is short of.
Summary of the invention
The object of the present invention is to provide a kind of job operation of forming position reference signal magnetic region on tape, it can make user's sets itself reference point, and the optional position on tape forms the magnetic region providing reference signal.
In order to achieve the above object, present invention employs following technical scheme:
For obtaining the tape that this has reference by location signal magnetic region, the invention provides a kind of job operation of forming position reference signal magnetic region on tape, it is characterized in that, it comprises the steps:
A. the rectangular tape that has the main magnetic region of the magnet pole widths such as multiple is taken;
B. selected at least one reference point on the long axis direction of this tape;
C. take one to magnetize part, be adjacent to this tape is positioned at this reference point location position side zone face on magnetize, and cover one of main magnetic region, in order to change cover one, main magnetic region magnetic pole be single magnetic pole, form the reference signal magnetic region that a magnet pole widths is different from his magnet pole widths of this main magnetic region;
D. this part that magnetizes is removed.
The part that magnetizes of taking in described step c is permanent magnet.
In described step c, described in the part that magnetizes cover at least two main magnetic regions separately one, and make the magnet pole widths of described reference signal magnetic region be greater than the magnet pole widths in this his portion, main magnetic region that each is not covered.
Advantage of the present invention is:
This reference by location signal magnetic region can be formed in the appropriate location on tape of magnetizing by the present invention, and without the need to providing independently magnetic field signal source by extra additional magnetic element as known techniques, in other words, technology contents provided by the present invention is the setting carrying out this reference by location signal magnetic region at use side, the manufacture end that need not magnetize at tape carries out, thus, not only end easy to use is answered the demand of actual job condition and independently selectes the setting position of this reference by location signal magnetic region, also can by use side sets itself, and providing of this processing smelting tool technology can be beneficial to by user's self-defining reference point or extreme position, improve the convenience implemented.
