Embodiment
See also Fig. 1, it is the exploded view of a preferred embodiment of scan module of the present invention.
The scan module 1000 of Fig. 1 comprises: a module bodies 100, and in a camera lens 101 wherein is set, and a sensor assembly 200.
Sensor assembly 200 comprise a circuit board 201, a sensing component 2012 that is Charged Coupled Device (charge couple device, CCD), an image sensor adjusting mechanism 202 and four adjusting levers 300.Will be in present embodiment with screw as adjusting lever.
Image sensor adjusting mechanism 202 comprises one first adjustment part 2021 and one second adjustment part 2022 between circuit board 201 and module bodies 100.The both sides of first adjustment part 2021 are extended a stator 2021A and two lappet 2021B respectively, and have a rectangle accommodating chamber 2021 in order to admit this image sensor 2012; Second adjustment part 2022 has four and pays hole 2022A, two elastic component 2022B, rectangles perforation 2022C and two second connecting portion 2022D to lock that should four through hole 2011A-2011D, and wherein the second connecting portion 2022D respectively has a groove 2022E.In with the embodiment of screw as adjusting lever 300, it is screw hole that lock is paid hole 2022A.
The combination and the function of following key diagram 1 assembly.CCD 2012 is fixed on the circuit board 201, and first adjustment part 2021 is fixed on the circuit board 201 by stator 2021A, and CCD2012 is accommodated in the rectangle accommodating chamber 2021C.The rectangle perforation 2022C of second adjustment part 2022 can allow rectangle accommodating chamber 2021C pass wherein, this moment, the lappet 2021B of first adjustment part 2021 also contacted the elastic force that also directly bears from elastic component 2022B with the elastic component 2022B of second adjustment part 2022, again four screws 300 are passed four of circuit board 201 perforation 2011A-2011D respectively and enter within four screw hole 2022A of second adjustment part 2022, but temporary transient lock screw not.At this moment, circuit board 201, first adjustment part 2021 and second adjustment part 2022 are tentatively combined.
Then circuit board 201, first adjustment part 2021 and second adjustment part of combining 2022 is installed to module bodies 100.Enter respectively by two first connecting portions 103 that make module bodies 100 within the groove 2022E of the second connecting portion 2022D of second adjustment part 2022, and rectangle accommodating chamber 2021 is mounted in the rectangular recess 102, and finish the preliminary combination of scan module 1000.
Image sensor adjusting mechanism 202 makes CCD 2012 be adjusted at 7 axial X1-X7.In detail, be applied to the elastic force on the lappet 2021B of first adjustment part 2021 by the elastic component 2022B of second adjustment part 2022, can be at the relative position of X1 axial adjustment second adjustment part 2022 and first adjustment part 2021, adjust the position of CCD 2012 with this in X1 axle (that is, parallel sweep direction A) direction.Finish the position adjustment of CCD 2012 by the relative position between X2 axle and X3 axial adjustment first connecting portion 103 and the second connecting portion 2022D at X2 axle and X3 axle.Wherein axles such as X1, X2 and X3 are orthogonal.
Then,, the position of CCD 2012 is adjusted on axles such as X4-X7, just makes circuit board 201 do by a small margin rotation along axle X4-X7 respectively, shown in the arrow on the X4-X7 as shown in Figure 1 by four screws, 300 blocked pines/tight degree.Wherein, the straight line parallel that then is formed by connecting with perforation 2011A and 2011B of axle X4.The straight line parallel that axle X5 and perforation 2011A and 2011C are formed by connecting.The straight line parallel that axle X6 and perforation 2011B and 2011C are formed by connecting.The straight line parallel that axle X7 and perforation 2011A and 2011D are formed by connecting.
Can detect the optimum position (this be known technology) of CCD 2012 by computer system, when the relative position between each composition assembly of scan module arrives the optimum position, carry out the final fixing step of scan module with respect to camera lens 101.This fixing step is included in and pours into viscose in the groove 2022E of the second connecting portion 2022D and with screw 300 lockings.After treating that viscose solidifies, scan module can be moved to the preparation process step of next scanner.
See also Fig. 2 and Fig. 3 A, Fig. 3 B.Fig. 2 finishes vertical view afterwards for scan module assembling of the present invention.Fig. 3 A is the profile of Fig. 2 in the B1 cross section, and Fig. 3 B is the profile of Fig. 2 in the B2 cross section.
What specify is, be with the embodiment of screw in the present embodiment as adjusting lever 300, and with the embodiment of screw hole as lock pair hole 2022A, but person skilled in the art scholar can otherwise implement an adjusting lever 300 and a lock pair hole 2022A according to it knowledge that possesses.For example, adjusting lever 300 can be the elongate bars with screw thread, its section can be polygon or circle, and a lock pair hole 2022A also needs not be screw hole, but can receive the cylinder shape groove of adjusting lever 300, and viscose hand-hole or screw hole are set on the cylindrical surface of groove, after the adjustment anchor clamps are finished the position adjustment of adjusting lever 300, viscose can be poured in the viscose hand-hole, or with the screw locking, and reach adjusting lever 300 and lock the fixed effect of paying between the 2022A of hole.
What specify is, viscose of the present invention is can be by ultraviolet ray and the viscose of accelerated solidification.That is to say that it is that transparent material is made that the present invention can make second adjustment part 2022, therefore can use ultraviolet irradiation second adjustment part 2022, make the viscose rapid solidification in the groove 2022E.Can shorten the time that scan module is done like this.Certainly, because CCD 2012 is accommodated in the rectangle accommodating chamber 2021 of first adjustment part 2021, and first adjustment part 2021 is to be made by opaque material, therefore with ultraviolet irradiation second adjustment part 2022 time, can't make CCD 2012 in the process of carrying out the position adjustment, be subjected to the interference of external light source.
Can understand in sum, scan module of the present invention can allow CCD axially adjust at 7 by first adjustment part, second adjustment part and four screws, has promoted the accuracy that the CCD position is adjusted.It is transparent making second adjustment part in addition, first adjustment part is opaque, and the transducer accommodating chamber is set at first adjustment part, make scan module of the present invention can use ultraviolet ray to quicken the setting rate of viscose, but can not allow CCD 2012 in the process of carrying out the position adjustment, be subjected to the interference of external light source, shorten the manufacturing time of scan module effectively.
Above embodiment only is explanation the present invention's usefulness, and other all should be considered as falling within the scope of the present invention not breaking away from the modification of being made under the mental condition of the present invention.
