In the present embodiment, by arranging the first reflecting part 1, second reflecting part 2, the 3rd reflecting part 3 and transmit-receive platform 5 on base 4, the back up pad 51 (back up pad 51 is circuit board) of transmit-receive platform 5 arranges laser head 52, power valve 54, receiving tube 55 and demoder 53, wherein power valve 54 and receiving tube 55 laser bar code scanning platform are in dormant state or running status all continuous firings, power valve 54 is constantly to emission of light outside this laser bar code scanning platform, and receiving tube 55 is the extraneous light be reflected back of perception constantly; When laser bar code scanning platform is in dormant state, motor 11 and laser head 52 all quit work; When user needs to use laser bar code scanning platform, hold an object (such as, bar code) be placed on laser bar code scanning platform scanning area, block the light that power valve 54 sends, thus the light that power valve 54 sends turns back to receiving tube 55 through this reflections off objects, receiving tube 55 is once perceive the light that power valve 54 sends, wake laser bar code scanning platform up at once, laser head 52 and motor 11 are started working, thus achieve quick, the automatic switchover of laser bar code scanning platform dormant state and running status, improve Consumer's Experience; Further, power valve and receiving tube are all located in back up pad, each other apart from little, avoid each reflecting part on the impact of the light emitted line of power valve, thus receiving tube can faster, receive power valve emission of light delicately; Simultaneously relative to the mode utilizing physical button to realize the switching of laser bar code scanning platform state, reduce production cost.
When this laser bar code scanning platform transfers duty to, laser head 52 and motor 11 in running order, motor 11 drives kaleidoscope prism 12 to rotate; First on laser head 52 gives off laser beam and exposes on curved mirror 31 the second catoptron 32; Then laser beam reflexes to the kaleidoscope prism 12 of rotation through the second catoptron 32, because kaleidoscope prism 12 quick rotation, the laser beam that then kaleidoscope prism 12 reflects moves to the other end of the first catoptron 21 from first catoptron 21 one end, again because kaleidoscope prism 12 velocity of rotation is very fast, on the first catoptron 21 surface, the laser beam of movement is fast after the first catoptron 21 reflects, form one at the stable light net of human eye, this laser bar code scanning platform utilizes this light net scanning barcode; The laser beam of last inswept bar code transfers to the first catoptron 21 after bar code reflection, again through the first catoptron 21 bounce transmission to kaleidoscope prism 12, again through kaleidoscope prism 12 bounce transmission to curved mirror 31, the beam transmission of scattering is converged again to demoder 53, the bar code that demoder 53 utilizes the identification of bar code standard to scan through curved mirror 31.
Further, with reference to Fig. 1, demoder 53 outside is provided with light filter 6, the side away from back up pad 51 of light filter 6 is provided with anti-dazzling screen 61, anti-dazzling screen 61 blocks the natural light from laser bar code scanning platform outside, light filter 6 filters out and sends the different light of optical maser wavelength from laser head 52, such as, the wavelength of the laser that laser head 52 is launched is 650nm, so light filter will filter out the light that all wavelengths is not 650nm, namely wavelength is only allowed to be that the light wave of 650nm passes through light filter, to reduce the scanning barcode veiling glare injecting demoder 53, and then improve the accuracy of demoder identification bar code.
Further, with reference to Fig. 7, the outside of kaleidoscope prism 12 is provided with the annular casing 7 around kaleidoscope prism 12, annular casing 7 is provided with the breach of the beam projecting reflected for kaleidoscope prism 12 towards the side of the first reflecting part 1, in the present embodiment, kaleidoscope prism 12 is precision opticss, its cost is very expensive, frangible, and kaleidoscope prism 12 high-speed rotation under the driving of motor 11, kaleidoscope prism 12 is contacted in order to prevent laser bar code scanning platform inside or outside parts or foreign material, in order to protect kaleidoscope prism better, annular casing 7 is set around kaleidoscope prism 12, prevent kaleidoscope prism 12 damaged.
Further, with reference to Fig. 4, first catoptron 21 comprises the first level crossing 211, second level crossing 212, 3rd level crossing 213, 4th level crossing 214, 5th level crossing 215 5 pieces square planar mirror, 3rd level crossing 213 be located at the first catoptron 21 enclose the middle part of semicircle, second level crossing 212 and the 4th level crossing 214 are symmetrically set in the both sides of the 3rd level crossing 213, first level crossing 211 and the 5th level crossing 215 are symmetrically set in the both sides of the 3rd level crossing 213, first level crossing 211, second level crossing 212, 3rd level crossing 213, 4th level crossing 214, the minute surface of the 5th level crossing 215 is all towards kaleidoscope prism, in the present embodiment, the laser reflected through kaleidoscope prism 12 moves to the 5th level crossing 215 from the first level crossing 211, different four faces of kaleidoscope prism 12 reflect the laser beam in four light path paths, article four, laser beam is through five flat mirror reflects of the first catoptron 21, form the light net be made up of 20 laser optical paths altogether, wherein said laser optical path is laser spot flashing fast on fixation locus in fact, when this frequency of flashing exceedes the limit that human eye can identify, the track so flashed fast at this laser spot of human eye just defines the light path of a stabilized illumination.
Further, four minute surfaces of kaleidoscope prism 12 are 85 degree to 86 degree relative to the angle of base 4 place plane, second catoptron 32 is 70 degree to 80 degree with the angle of base 4 place plane, first level crossing 211, second level crossing 212, the 3rd level crossing 213, the 4th level crossing 214, the 5th level crossing 215 are 40 degree to 42 degree with the angle of base 4 place plane, and the radius of curved mirror 31 place spheroid is 142mm.In the present embodiment, under the cooperation of kaleidoscope prism 12, first catoptron 21, second catoptron 32 and curved mirror 31 angle and curvature, optimize the light transmission path of laser head 52 Emission Lasers, make it evenly and be beneficial to optically focused, simultaneously, strengthen the signal that light filter 6 receives, the light signal that demoder 53 is received is more comprehensive, further increases the accuracy rate that demoder 53 identifies bar code.
Further, power valve 54 is infrared emission tube, and receiving tube 55 is infrared receiver tube, and motor 11 and laser head 52 are all electrically connected with power valve 54 and receiving tube 55.Because infrared ray is invisible light, when this laser bar code scanning platform is in dormant state, the infrared ray user sent by infrared ray sending tube cannot see, and reduces the impact on user, avoids light pollution.
Further, curved mirror 31 is aspheric mirror, and the Penetration ration of aspheric mirror is higher, dull thread is distorted, imaging is more clear, thus curved mirror 31 spotlight effect is better, and then the light converging to demoder 53 is subject to external interference less, further reduces the error that demoder 53 identifies bar code.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
