The specific embodiment
At first, consult as Fig. 3 to shown in Figure 6, a kind of purposes of rectifying a deviation of the present invention with line with the double luminous source structure of limit dual purpose sensor, wherein:
This dual purpose sensor 1 inboard middle section miter angle is tilting single light splitting piece 15, the shadow 3 on the ground paper 2 that is positioned at the setting detection-sensitive distance is beaten in the 16 back ejaculations to outer lens that the light source that first row's light emitting device group (LED) 10 and second row's light emitting device group (LED), the 11 rhombus perforate photochoppers 14 that see through send can be reflexed to dual purpose sensor 1 by light splitting piece 15, owing to be two row's light emitting device group (LED) 10,11 is staggered luminous, so the signal that light emitting source sent is two groups, and beat the single receiving element 17 that the shadow 3 reflected back dual purpose sensors 1 inner end edge on ground paper 2 is provided with, can adopt the staggered mode that receives synchronously can receive two groups of corresponding signal I equally, II.
Consult Fig. 7 to shown in Figure 11, wherein Fig. 8 shows the flow process of simple light splitting piece 15 and then shows shadow 3 and the correlation of 4 of its luminous intensities that is produced, and reaches the feature that luminous intensity 4 is linear change;
As Fig. 7, shown in Figure 8: a kind of purposes of rectifying a deviation of the present invention beat shadow 3 on ground paper 2 with line with the limit double light emitting source of dual purpose sensor, because two row's light emitting device group (LED) 10,11 can utilize it to be in two groups of controlling resistances 12 of back of circuit board respectively, 13, set luminous intensity according to serve as reasons strong diminuendo or of ordering by weak crescendo, can control the rhombus that is shaped as that each light source component emits adding rhombus hole 140 that rhombus perforate photochopper 14 is offered, the detection setpoint distance of ground paper 2 is promptly selected the plane of each adjacent beams inner edge meeting intersection point in this light beam for use, after light source is via light splitting piece reflection and front lens group, can be imaged on and obtain two vertical bar light on the ground paper 2, wherein one imaging is promptly shown in shadow 3, these its shadow 3 pairing luminous intensities 4 can be the vertical bar light source of linear change from left to right, for example: it is the strongest to suppose that electroluminescent lamp 100 is regulated to the intensity of light source, it is maximum naturally then to beat the luminous intensity 4-100 that the shadow 3-100 on ground paper 2 produced, be that electroluminescent lamp 101 times is strong in regular turn, in the middle of the electroluminescent lamp 102, a little less than the electroluminescent lamp 103 times, and electroluminescent lamp 104 is the most weak, therefore beat the luminous intensity 4-101 of the shadow on ground paper 2 in regular turn, 4-102,4-103, the summit of its rhombus of 4-104 is then gradually low, if luminous intensity 4-100 with each rhombus shadow, 4-101,4-102,4-103, the summit of 4-104 is linked up with the luminous intensity of whole shadow and is seen, then is the linear change of a vertical bar light source.
Extremely shown in Figure 11 as Fig. 9: as in this design, to have one because receive Yuan spare Only, so these two vertical bar light source A and vertical bar light source B just adopt staggered emission and the staggered mode (as shown in figure 10) that receives synchronously to beat shadow 3A and the pairing reflected signal size of shadow 3B that produces at ground paper 2 to obtain vertical bar light source A and vertical bar light source B, and the reflection ray of shadow 3A and shadow 3B can change along with the move left and right of lines 5 to be measured.As shown in figure 11, because the brightness of the luminous intensity 4B of the luminous intensity 4A of shadow and shadow is to be linear rightabout variation in the Z of its range of linearity, so the size variation of the received signal difference that these two shadows 3A and 3B are produced promptly can be used to detect the degree of color lines skew.
Because tool two row's light emitting device group (LED) 10, send two groups of light so 11 can interlock, when getting to ground paper 2, wired or limit waits for that the mobile situation of survey line bar 5 can cause the tangible difference in reflectivity on the ground paper 2, nature can influence the light signal of reflected back dual purpose sensor 1, light reflected is back to single receiving element 17 receptions through the border 16 of passing through inside is worn, and single receiving element 17 receive signal via staggered receive synchronously and in addition signal handle and can obtain two groups of signal I, II, and the user can utilize switch to switch with the converting analogue circuit, with two group of received signal I as required when using, II is treated to I-II or I+II and detects or survey with frontier inspection with line being used for.
And the present invention is when the line at monitoring utmost point edge, and the light source that can turn off two outsides about each row's light-emitting component to be avoiding running off the edge of ground paper, and can have detectability to the straight line at utmost point edge equally.
In addition, the present invention is for obtaining the reaction that limit or linear light degree change really, and this two rows light-emitting component can be that a row is that blue light another row that arranges in pairs or groups is a gold-tinted with its complementary colours, to capture any colour code really.In addition, this two rows light source also can be for example white, also can be all the LED lamp of homochromy spectrum.
The present invention compared with prior art has following advantage:
1. the zone of sensor plan correction is two residing intervals of light beam, and this zone is order directly Depending on, so this zone that can detect very clear and definite just.
2. two light beams are made up of the light-emitting component of the complementary wavelength of tool, can avoid like this showing The phenomenon that causes detection difficult in the design because the spectrum of line color and polishing light source is close is arranged.
The above only is preferred embodiment of the present invention, is not that the present invention is done any shape Restriction on the formula, every foundation technical spirit of the present invention to above embodiment do any simple Modification, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
In sum, the present invention accords with on structural design, use practicality and cost benefit fully It is required to close industry development, and the structure that discloses also is to have unprecedented innovative structure, has Novelty, creativeness, practicality meet the regulation of relevant patent of invention important document, so mention in accordance with the law Application.
