Abstract
The utility model discloses a high speed miniature laser scanning device which comprises a laser generator, a concave surface reflector, a photoelectric sensor and a polyhedral reflector installed on a miniature direct current motor. The utility model has simple structure, and the scanning speed can be enhanced by more than 7 times compared with the traditional scanner.
Description
Technical field
The utility model relates to a kind of miniature laser bar-code scanner.
Background technology
Now generally adopt bar code to distinguish different article, especially in occasions such as logistics, large supermarkets, read bar code and need use laser scanner, the present miniature laser bar-code scanner that uses, be that combination by one group of wabbler mechanism and solenoid becomes 1 single-point laser into the single line laser bundle, thereby reach the purpose of scanning.Though this structure can realize the purpose that scans, because the inertia effect of wabbler mechanism, sweep velocity is the highest can only to reach per second 10 times back and forth, thereby yard time of reading of scanner is not further improved, and has limited the lifting of scan efficiency.
The utility model content
The utility model aims to provide a kind of mini laser scanning device, can increase substantially sweep velocity, and is simple in structure.
A kind of high speed mini laser scanning device comprises laser generator, concave mirror, and photoelectric sensor is installed in the many ribs reflective mirror on the DC micromotor.
Preferably, described many ribs reflective mirror is five rib reflective mirrors.
Preferably, described many ribs reflective mirror is six rib reflective mirrors.
The utility model only replaces the wabbler mechanism of existing scanner and electromagnetism electricity to enclose with the many ribs reflective mirror that is installed on the DC micromotor, and is simple in structure, can improve sweep velocity more than 7 times.
Description of drawings
Fig. 1 is existing scanner structure synoptic diagram.
Fig. 2 is the utility model structural representation.
Among the figure: 1-photoelectric sensor, 2-concave mirror, 3-laser generator, 4-scanning plane, 5-reflective mirror, 6-wabbler mechanism, 7-solenoid, many ribs of 8-reflective mirror, 9-direct current generator.
Embodiment
The mini laser scanning instrument that uses as shown in Figure 1 at present, comprise laser generator 3, reflective mirror 5, concave mirror 2, photoelectric sensor 1, the single-point laser that laser generator 3 sends becomes the single line laser bundle through reflective mirror 5 under wabbler mechanism 6 and solenoid 7 effects, finish the scanning to scanning plane 4.Because wabbler mechanism 6 has inertia, sweep velocity is the highest can only to reach per second 10 times back and forth, thereby yard time of reading of scanner is greatly limited, and has limited the lifting of scan efficiency.
The utility model high speed mini laser scanning device as shown in Figure 2, comprise laser generator 3, reflective mirror 5, concave mirror 2, photoelectric sensor 1 is installed in the many ribs reflective mirror 8 on the DC micromotor 9 in addition, many ribs reflective mirror 8 rotation under direct current generator 9 effects, the preferred five rib reflective mirrors of many ribs reflective mirror also can be six rib reflective mirrors.
The utility model can increase substantially sweep velocity, as use five rib reflective mirrors, when DC micromotor keeps 1000 rev/mins, one-line scanning times N=1000*5=5000 time/minute, with respect to 10 times/second * of existing scanning 60=600 time/minute, improve sweep velocity more than 7 times, thereby promote the efficient of scanner greatly.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
Claims (3)
1. a high speed mini laser scanning device comprises laser generator (3), concave mirror (2), and photoelectric sensor (1) is characterized in that: be installed in the many ribs reflective mirror (8) on the DC micromotor (9) in addition.
