Description
Technical field
The present invention is a kind of method of automatic adjustment bare engine module, particularly about a kind of control by software program, adjusts automatically and makes the optimum position of CCD module on bare engine module, is assembled out the scanner of high image quality.
Background technology
Recently, under the drive of high-tech industry, the electronic correlation industry is all flourish, every modern product, and as computing machine, computer peripheral equipment outfit, information household appliances (IA) and business machine etc., its function and outward appearance all had significant progress more in the past.
With the scanner is example, but in time of a few years, its resolution is just progressive to more than the 1200dpi, if utilize interpolation method to handle, even can be up to 9600dpi, so present scanner market really is to fragment a country by rivaling warlords, it is very fierce to compete, and all big enterprises' better usefulness of research and development of racking one's brains invariably is high-quality and have more the machine of price advantage, to win consumer's favor, increase the occupation rate in market.
Present scanner on the market, utilize charge-coupled device (CCD) (Charge CoupledDevice mostly, C D) as optical sensing subassembly, the incident light that comes so as to the reflection of sensing scan pattern, therefore, for guaranteeing scanning quality, certainly will need with the accurate adjustment in the position of CCD module, to avoid the scan-image distortion.
Press, existing bare engine module manual adjustment system, as shown in Figure 1, it is to include a computing machine 1a, a bare engine module 2a and one to adjust tool 3a, wherein:
Have a signal transmission terminal mouth 11a (can be USB transmit port etc.), a routine analyzer and a database (figure slightly) in this computing machine 1a, and this routine analyzer has location/image quality analytic function.
This bare engine module 2a can supply to put a CCD module 4a, and is covered with a standard map (targetchart) (figure slightly), and this bare engine module 2a itself can and do reflection and use for generation light source, scan-image.
This adjustment tool 3a includes a board 31a, a plurality of drive shaft 32a and a bare engine module control circuit 33a again, wherein:
This board 31a can be for putting this bare engine module 2a and being fixed.
These drive shafts 32a is the appropriate position that is connected to this board 31a, about bootable this board 31a does when manually rotating with box lunch, about or the moving of direction of scanning such as front and back (if five be directions X, Y direction, Z direction, around the Z sense of rotation and around the Y sense of rotation, if three are directions X, Y direction and reach around the Z sense of rotation).
This bare engine module control circuit 33a is connected electrically in this bare engine module 2a, and be connected with the signal transmission terminal mouth 11a of this computing machine 1a by a signal transmission line 35a (can be USB transmission line etc.), be to accept the bare engine module control signal that this computing machine 1a end sends, to drive this bare engine module 2a this CCD module 4a is done the image scan action, simultaneously obtained sensing image is back to this computing machine 1a.
In Fig. 2, disclosed the operational flowchart of existing manual adjustment bare engine module, it includes the following step:
Step 101: at first, a bare engine module 2a to be adjusted is set on the board 31a of this adjustment tool 3a, and this bare engine module 2a and CCD module 4a are fixed;
Step 102: in this computing machine 1a execution analyzer;
Step 103: detect this bare engine module control circuit 33a by this routine analyzer and be linked to this computing machine 1a?
If not, then getting back to step 103 continues to detect;
If then enter step 104;
Step 104: this bare engine module control circuit of this routine analyzer auto-initiation 33a;
Step 105: this computing machine 1a sends a bare engine module by this signal transmission terminal mouth 11a and controls signal to this bare engine module control circuit 33a, carries out the image scan program to trigger this bare engine module 2a, and obtains the image that this CCD module 4a is sensed.
Step 106: this routine analyzer is analyzed the image that is scanned, and with the contrast of the image data of this standard map, to judge the position of this CCD module 4a;
Step 107: calculate this CCD module 4a in the position of three of X, Y, Z and the deviation angle of Y, Z diaxon, and calculate the image quality that scans image.
Step 108: this routine analyzer with result of calculation with icon display on the screen of this computing machine 1a, and show respectively that according to predetermined dimension whether qualified every result is;
Does step 109: the operator adjust from the screen judgement and finishes?
If not, the operator then according to the analysis icon and the data of execution result, rotates suitable transmission component 33a, revises this CCD module 4a image sensing position and image quality (step 112) partly, and gets back to step 106.
If then enter step 110;
Step 110: because the image quality of this CCD module 4a and location be all in the scope of quality specification, just can be with this CCD module 4a image sensing stationkeeping partly, and with data storing such as its position and image qualities to the database of this computing machine 1a;
Step 111: carry out a glue, rough 15-30 is after second, and this CCD module 4a just is fixed on this bare engine module 2a, this bare engine module 2a is gone up from this board 31a take out again, promptly finishes the operating process of manual adjustment.
Wherein, also can utilize fixation kits such as screw that this CCD module 4a is fixed on this bare engine module 2a in this step 111.
By above-mentioned operating process as can be known, the position of CCD module 4a mainly is by operator's manual adjustment, and individual factors such as operator's subjective differences and proficiency but directly have influence on the result that whole bare engine module 2a adjusts; In the practical experience of manual adjustment, when senior operator repeats to adjust with a collection of bare engine module 2a, there is the bare engine module 2a of part after adjustment, still can produce difference, form unacceptable product.
As from the foregoing, the method for above-mentioned existing manual adjustment bare engine module on reality is used, obviously has inconvenience and exist with shortcoming, and necessity is improved.
The inventor is thoughts on the problem of above-mentioned existence, and the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the present invention of above-mentioned shortcoming finally.
