Description
Technical field
The utility model relates to a kind of lens pillar assembly of contact image scan module, refers to be applied to the contact image scan module of products such as scanner (Scanner), multifunctional paper feeding machine (MFP) and duplicating machine especially.
Background technology
The principle of work of scanner (Scanner) is that irradiate light that light source is produced is to contribution to be scanned, reflection through lens set, reassociate in charge coupled cell (Charge-Coupled Device, CCD) or CMOS (Complementary Metal Oxide Semiconductor) (Complementary Metal OxideSemiconductor, CMOS) after receiving by it on, utilize the photo-sensitive cell of this type to change light signal into electric signal, and then produce pixel (Pixel) data of analog or digital kenel.
In the process of scanning, because CCD can detect the light that zones of different on the image reflects varying strength, therefore utilize the principle of the more light of the less light of regional reflex darker on the paper, brighter regional reflex, the light wave that CCD reflected can be converted to the analog or digital data, this electric signal can be directly proportional with light intensity, at last, the literal or the image scan software that re-use with the scanner compatibility read in these data, and it is reassembled as the computer image file.
Because excellent scanner capture performance relies on ripe photocontrol technology, so the quality of image scanning module is not only important, and influence one of main element of scanner running performance especially.
The image scanning module of the scanner of main flow is a kind of contact image scan module (contact image sensor module that is called as at present, CISM) technology, it is with modular kenel, and light source, lens pillar, sensing substrate and shell etc. are combined.
See also Fig. 1, it is the structural representation of the contact image scan module in the known technology.Wherein, contact image scan module 10 is by diode light-source 11, lens pillar (Rod Lens) 12, housing (Housing) 13 and 14 common be combined intos of circuit board; And also has a photo-sensitive cell 141 that constitutes by CCD or CMOS on the circuit board 14.
In the anabolic process of lens pillar 12 and housing 13, common way is earlier lens pillar 12 to be inserted in the storage tank of housing 13, after fixing glue on the two point, imposes the irradiation of ultraviolet light again, makes lens pillar 12 be fixed on the housing 13.
See also Fig. 2, it is the top view of housing 13.By finding out among the figure, housing 13 has in order to the storage tank 131 of ccontaining lens pillar 12 and a plurality of somes glue grooves 132.
See also Fig. 3, the synoptic diagram when it makes up for lens pillar 12 and housing 13.By finding out among the figure, common way is earlier lens pillar 12 to be inserted in the storage tank of housing 13, utilizes sebific duct 20 point in each some glue groove 132 to go up fixing glue again.Then, again whole module is put into irradiating ultraviolet light in the ultraviolet ray machine (not shown), make and the fixing glue sclerosis, make lens pillar 12 can not cause the quality of image bad because of the vibrations skew so lens pillar 12 just can be combined closely by fixing glue and housing 13.
Yet under above-mentioned method of operating, when sebific duct 20 behind the glue separated with a glue groove 132, there was the collodion silk hanging in regular meeting below sebific duct 20, and this collodion silk attaches when sebific duct 20 moves easily on lens pillar 12; And attach collodion silk on lens pillar 12 surfaces, and just can form film through after the irradiation of ultraviolet light again, this film can cause image blur even situation that can't imaging to produce, and has a strong impact on the acceptance rate of contact image scan module 10.
Because this film cause also can be because of the kind of use fixing glue and residual quantity and difference for the influence of imaging, so at this film, must add the formality into one cleaning in manufacturing process, thereby has increased the cost in the manufacturing.In addition, even if in manufacturing process, use alcohol to be cleaned, still have the film that very thin one deck naked eyes are difficult for seeing unavoidably and attach on the surface of lens pillar 12, the product that makes manufacturing come out does not meet present electronics industry in mass-produced high-quality and the demand cheaply emphasized simultaneously.
