Description
Technical field
The utility model relates to a kind of Optical module optical path adjustment device.
Background technology
In recent years, under the drive of high-tech industry, all electronic correlation industries are all flourish, every modern product, as computing machine, computer peripheral, household electrical appliances and affairs equipment or the like, no matter function or outward appearance, compare all has significant progress in the past.With the scanner is example, and just in a few years time not, resolution is just progressive to more than 1,200 (point/inch), if utilize interpolation method to handle, and resolution even can be at a tremendous pace up to 9,600 (point/inch).Present scanner market is to fragment a country by rivaling warlords, and it is very fierce to compete, and each big factory research and development usefulness of there's no one who doesn't or isn't racking one's brains is better and have more the machine of price advantage, to win consumer's favor, increases market share.Therefore, how improving in the limited budgetary product usefulness that makes, is the direction that all research staff make joint efforts.
Scanner on the market utilizes charge-coupled device (CCD) (Charge Coupled Device mostly at present; CCD) as optical sensing subassembly, the incident light that comes in order to the reflection of sensing self-scanning pattern.For scan pattern can verily be videoed on the charge-coupled device (CCD) module, the direct of travel of incident light must be vertical with the charge-coupled device (CCD) module, to reach best image capture effect.Therefore,, certainly will need to adjust light path, show true in the hope of making scan-image for improving quality of scanning.
In actual applications, the charge-coupled device (CCD) module is arranged on the case for lens of optical module, and the incident light of scan-image then is mapped across on the charge-coupled device (CCD) module by case for lens.After charge-coupled device (CCD) module and case for lens assembling finish, be collectively referred to as optical module (Optical Module), survey, inseparable relation is arranged with the quality of image so the light path of optical module is transferred, at present, an industry general use-pattern can be divided into three accent surveys and two kinds of systems of five accent surveys.The adjustment mode of so-called three regulating and measuring systems, promptly directly adjust the charge-coupled device (CCD) module " up and down ", " about " reach three directions such as " vertically rotating ", make the charge-coupled device (CCD) module be positioned the appropriate location, camera lens is adjusted in front and back again, finishes the adjustment of focal length.On the other hand, so-called five regulating and measuring systems, promptly by charge-coupled device (CCD) module and some parts that cooperate, earlier case for lens is fixed, utilize again adjusting mechanism directly adjust " up and down " of charge-coupled device (CCD) module, " about ", " vertical rotation ", " horizontally rotating " reach five directions such as " front and back ", promptly what is called is five.
Please refer to Fig. 1, it has illustrated three exploded views of transferring the photometry module.Transfer photometry module 200 to include case for lens 210 and charge-coupled device (CCD) module 220 for three, wherein case for lens 210 has the window of coupling 210a, in order to couple with charge-coupled device (CCD) module 220.As shown in the figure, couple window 210a place and be provided with screw hole 240, during assembling, only need screw 230 is locked in the screw hole 240 by charge-coupled device (CCD) module 220, charge-coupled device (CCD) module 220 can be fixedly arranged on and couple window 210a place.
Transfer the accent survey mode of photometry module 200 the simplest and easy for these three, because of charge-coupled device (CCD) module 220 is directly to be fixedly arranged on the case for lens 210, therefore light path is transferred when surveying, only need direct adjustment charge-coupled device (CCD) module 220 " up and down ", " about " with three directions such as " vertical rotations ", can make charge-coupled device (CCD) module 220 be positioned the appropriate location.After transferring survey to finish, can finish the focusing program by the focal length of adjusting case for lens 210.It should be noted that, owing to focusing adjustment is to utilize focus to move forward and backward along X-direction to reach the adjustment purpose, therefore, with regard to the relative position of focus and charge-coupled device (CCD) module 220, it is constant to can be considered the focal position during focusing, and charge-coupled device (CCD) module 220 forwards, backwards direction move, one of transfer to survey so also there is the people that focus process is considered as light path, and claim that this structure is the four shaft type regulator optical module.But focus process can apparent charge coupling device module 220 be the relative motion of X-direction only, but not actual moving transferred the photometry module so claim this structure to be three, should be more rigorous and appropriate saying.
In sum, transfer the advantage of photometry module 200 to be for these three, it can be finished three light paths and transfer survey work by minimum adjustment parts, so transfer the required anchor clamps cost of survey also minimum, widely most at present manufacturers adopt.On the other hand, produce instinct and reduce to minimum for making, case for lens 210 adopts the mode of plastics ejection formation to make usually, therefore, if in the process that plastics penetrate, flaw is arranged slightly, makes the air spots that couples window 210a capable in the yz surface, when charge-coupled device (CCD) module 220 with couple window 210a fixing after, the surface of charge-coupled device (CCD) module 220 just can't be parallel with the yz surface.At this moment, even if through three programs of transferring survey, owing to three accent are surveyed and can't be adjusted at the horizontal rotatio direction of charge-coupled device (CCD) module 220, so this shortcoming also can't overcome.Therefore, because three adjustment functions of transferring photometry module shortcoming horizontal rotatio direction so transfer the survey result also can't reach optimization naturally, reduce quality of scanning.
Five and transfer the photometry modules in order to improve above-mentioned shortcoming, just to develop, respectively at " up and down " of charge-coupled device (CCD) module, " about ", " vertical rotation ", " horizontally rotating " reach " front and back " five directions and adjusted, with the raising quality of scanning.Please refer to Fig. 2, it has illustrated five exploded views of transferring the photometry module.Transfer photometry module 300 to comprise case for lens 310, charge-coupled device (CCD) module 320, assembly 330, assembly 340 and assembly 350 for five, wherein case for lens 310 has the window of coupling 310a, in order to couple with assembly 330,320 of charge-coupled device (CCD) modules are coupled to assembly 350.Then please be simultaneously with reference to Fig. 1 and Fig. 2, difference between two figure is assembly 330, assembly 340 and assembly 350 threes, significantly five to transfer photometry module 300 are combinations by assembly 330, assembly 340 and assembly 350 threes, charge-coupled device (CCD) module 320 is carried out five transfers the work of surveying.Moreover these five regulating and measuring systems are to adjust assembly 330, assembly 340 and assembly 350 threes by line up procedure, and charge-coupled device (CCD) module 320 is carried out the accent survey work of five kinds of directions, and its precision greatly improves.Even so, these five to transfer photometry module 300 required accent to survey the anchor clamps cost very high, and the parts of required cooperation are also maximum, so cost is also the highest, make the product competitiveness reduction relatively.
From the above, the shortcoming of traditional optical module is as follows:
1, transfers the photometry module to be adjusted for three, transfer the survey result to reach optimization so can't make at the horizontal rotatio direction of charge-coupled device (CCD) module.
Though 2, transfer the photometry module to carry out five accent surveys to the charge-coupled device (CCD) module for five, the parts of required cooperation are also many, so cost is also the highest, product competitiveness reduced.
