Description
Technical field
The present invention relates to bar code scan rifle.
Background technology
Bar code (claiming again bar code) is a plurality of secret notes and the blank that width is not waited, and arranges, in order to express the graphical identifier of one group of information according to certain coding rule.Common bar code is the pattern of parallel lines that the secret note (abbreviation bar) that differed greatly by reflectivity and informal voucher (being called for short empty) are lined up.Bar code can mark many information such as producing country, manufacturing firm, trade name, date of manufacture, book classification number, mail start-stop place, classification, the date of article, thereby is all widely used in many fields such as commodity circulation, taking care of books, postal management, banking systems.
The structure of existing bar code scan rifle as shown in Figure 1 on the market, the light beam that Laser emission is sent, through the reflection of concave mirror, arrive the front end face of wig-wag, wherein the front end face of wig-wag is catoptron, after wig-wag swings, light beam changes direction and then in the bar code being scanned, forms straight line hot spot, thereby realizes the dynamic scan to bar code.The reflected light of scanning, after wig-wag, is converged on receiver by concave mirror, carries out signal-obtaining.
But such scanner complex structure, volume are large, are unfavorable for miniaturization, and the manufacturing cost of concave mirror is high, thereby improved the cost of scanner.
Summary of the invention
Not enough for above-mentioned prior art, the technical problem to be solved in the present invention is to provide a kind of scanner that is different from existing structure, and simplified structure, reduces costs, and meets miniaturization demand.
For solving the problems of the technologies described above, the technical solution used in the present invention is that bar code scan rifle structure, comprises substrate, and is fixedly mounted on optical transmitting set and optical receiver on substrate; The front end of substrate is logical light mouth; The wig-wag that also comprises convex lens and horizontal hunting; Wig-wag is arranged on substrate; Optical transmitting set and wig-wag lay respectively at the both sides of optical receiver; The transmit direction of optical transmitting set becomes angle with the optical axis direction of optical receiver; Described logical light mouth is positioned on the optical axis of optical receiver; On described wig-wag, be provided with for the catoptron to logical light mouth the light reflection of optical transmitting set, this catoptron is positioned at transmit direction the place ahead of optical transmitting set; Described convex lens are installed on the front end of optical receiver.Such technical scheme, has rearranged the position of light path devices, has removed the high concave mirror of cost from, reduces costs, and is conducive to miniaturization.
Further technical scheme is that described optical transmitting set and optical receiver are all positioned at the rear of described catoptron.Such scheme makes each device can be more close, further meets miniaturization needs.
Further technical scheme is, the angle of the transmit direction of described optical transmitting set and optical receiver optical axis direction is 30 °-65 °.Such structure makes the distribution of device more reasonable, further meets miniaturization needs.
Further technical scheme is, the vibration amplitude of wig-wag is 18 °-25 °.
Bar code scan rifle structure of the present invention, has saved concave mirror structure, and each device in light path is rearranged, and simplifies the structure, and meets miniaturization demand.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 2, bar code scan rifle structure of the present invention, comprises the wig-wag 5 of substrate 1, optical transmitting set 2, optical receiver 3, convex lens 4 and horizontal hunting.Optical transmitting set 2, optical receiver 3 and wig-wag 5 are installed on substrate 1, and wherein, wig-wag 5 horizontal huntings refer to that the plane parallel at swinging track place of swing is in the plane at substrate 1 place, and under general service condition, substrate 1 is close to surface level.The front end of substrate 1 (only marks the position by mouth for leading to light mouth 11 in Fig. 2, this part that does not represent substrate 1 is exactly logical light mouth 11), this logical light mouth 11 passes through for the light that allows optical transmitting set 2 send, and shines bar code 7 places, and allows the utilizing emitted light being reflected by bar code 7 places enter.Optical transmitting set 2 and wig-wag 5 lay respectively at the both sides of optical receiver 3, described both sides refer to, the optical axis of optical receiver 3 of take is boundary, optical transmitting set 2 and wig-wag 5 lay respectively at the both sides of this optical axis, as shown in Figure 2, in the present embodiment, optical transmitting set 2 is arranged in the left side (i.e. the upside of figure) of optical receiver 3, and wig-wag 5 is positioned at the right side of optical receiver 3.The transmit direction of optical transmitting set 2 becomes angle with the optical axis direction of optical receiver 3, described logical light mouth 11 is positioned on the optical axis of optical receiver 3, on described wig-wag 5, be provided with for the catoptron 6 to logical light mouth 11 the light reflection of optical transmitting set 2, this catoptron 6 is positioned at transmit direction the place ahead of optical transmitting set 2, after the light arrival catoptron 6 that optical transmitting set 2 sends, because catoptron 6 produces to-and-fro movement under wig-wag 5 drives, make the discrete scanning light beam that is formed with the level of the time difference of light, wherein the vibration amplitude of wig-wag 5 is preferably 18 °-25 °, in the present embodiment, be 23 °.Scanning light beam is from Tong Guangkou 11 outgoing finger shape codes 7, and informal voucher and secret note through on bar code 7, enter the reflected light that light signal changes to some extent again from Tong Guangkou 11.In the present embodiment, described optical transmitting set 2 and optical receiver 3 are all positioned at the rear of described catoptron 6, and the rear of catoptron 6 refers to, take the position of catoptron 6 is reference point, away from the direction of logical light mouth 11, i.e. left side shown in figure; Such mode makes each main devices compacter, further realizes miniaturization.Wherein, the angle of the transmit direction of described optical transmitting set 2 and optical receiver 3 optical axis directions is 30 °-65 °, is 45 ° in the present embodiment; Because the volumes of optical transmitting set 2 and optical receiver 3 itself can not be ignored, such angle can meet device further near requirement under, guarantee the enforcement of light path.Described convex lens 4 are installed on the front end of optical receiver 3, and the optical axis of optical receiver 3, convex lens 4 and logical light mouth 11 are located along the same line.Described reflected light, via the effect of converging of convex lens 4, is finally received by optical receiver 3.In the present invention, catoptron 6 does not relate to the recovery of bar code diffuse light, thus in application, can be designed very little, even if to such an extent as to the place ahead that is placed in optical receiver 3 is also not enough to block recovery light.Thereby the Electromagnetic Drive coil of the wig-wag 5 being used in conjunction with also can be done littlely, further reduced volume.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
