Description of the drawings
Attached drawing is only used for showing the purpose of specific embodiment, and is not considered as limitation of the present invention, in entire attached drawing
In, identical reference mark represents identical component.
Fig. 1 is clean method flow chart.
Specific embodiment
The preferred embodiment of the present invention is specifically described below in conjunction with the accompanying drawings, wherein, attached drawing forms the application part, and
It is used to illustrate the principle of the present invention together with embodiments of the present invention.
The specific embodiment of the present invention, discloses a kind of large area array CCD optical window clean methods, as shown in Figure 1, including such as
Lower step：
Step 1：Using dust exhaust apparatus, CCD optical windows surface, surrounding gap and camera perimeter frame formation surface are drawn
On removable attachment.
To prevent electrostatic, camera is damaged, the dust exhaust apparatus includes anti-static part.The anti-static part installation
On the dop of dust exhaust apparatus front end, including hose, metal hollow pipe and conductive rubber, described hose one end are fixed on dust suction
On the dop of device front end, the other end is connected with one end of the metal hollow pipe, and the other end of the metal hollow pipe is equipped with
The conductive rubber.
During the dust exhaust apparatus work, the removable attachment on camera enters dust suction by metal hollow pipe to hose and fills
Put inside.During operation, the necessary wrist ring set anti-electrostatic wrist ring of camera cleanup crew, bracelet is connected with the ground wire of operation console, clearly
Worker holds metal tube when clean, and is contacted between conductive rubber or with large area array CCD optical windows.Make the electrostatic generated during dust suction
It by conductive rubber, is transmitted on metal tube, is then conducted by human body to greatly.
Step 2：To securely removable attachment remaining on CCD chip peripheral structure frame surface using bonding paper self-adhesive tape
It is viscous to take；
Step 3：Non-moving attachment remaining on CCD chip peripheral structure frame surface is cleaned；
Non-moving attachment remaining on organic solvent wiping CCD chip peripheral structure frame surface is dipped with burnisher,
The burnisher is cotton cleaning rod, and cleaning head is made of long wool pure cotton, and appearance cleaning is smooth, no floating soft flocks.
After being wiped using cleaning rod, ensure peripheral frame without remaining non-moving attachment.
The organic solvent is the absolute ethyl alcohol just sealed off, and concentration is not less than 99%, ethyl alcohol also unadsorbed sky when just sealing off
Moisture in gas, using this ethanol CCD optical windows surface, it is preferable to parch effect, will not remain water stain, can observe in real time
Cleaning effect.
Step 4：Non-moving attachment remaining on CCD optical windows surface is cleaned；
Non-moving attachment remaining on organic solvent wiping CCD optical windows surface is dipped with burnisher, until using flashlight

It is identical in three.
Step 5：The attachment on CCD optical windows surface is further cleaned using optics antistatic cleaning rubber；
1) optics antistatic cleaning rubber is uniformly applied on CCD optical windows face, cleaning rubber should cover CCD optical windows, then
It is placed on the testing stand of hundred grades of cleanliness factors, glue-line is waited for parch；
2) it after glue-line parches, is glued with jointing tape and takes removable attachment remaining on CCD chip peripheral structure frame surface；
3) the glue-line edge parched is gently provoked using nonmetallic thin bar, removes the cleaning rubber parched.
The cleaning rubber is First ContactTM antistatic cleaning rubbers, and the cleaning capacity of the glue is strong, and can be prevented clear
It is clean front and rear in optical window surface generation electrostatic.
Step 6：The cleaning effect of visual confirmation CCD optical windows；
With flashlight irradiation CCD optical windows surface, visual inspection is with the presence or absence of removable attachment, if there is removable attachment
Object with stick gently sticky removing is bonded, if there is non-moving attachment, repeats step 4~step 6；
Step 7：It is powered and checks the cleaning effect of CCD optical windows；
It is powered after camera (containing camera lens) is assembled, to illumination, uniform lamp plate imaging, checks for attachment shape
Into blackening picture, be, then according to step 4~step 7 to CCD optical windows carry out repeat cleaning.
In conclusion large area array CCD optical window clean methods disclosed in the present embodiment, produce CCD chip when avoiding cleaning
Raw electrostatic injury；The blackening on CCD optical windows surface reduces about 10 times as number after primary cleaning；Cleaning time was reduced by 1~3 day
To being no more than 3 hours, production efficiency is greatly improved；Reduce the secondary pollution in environmental test after the completion of camera assembles.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
