Description
Technical field
The invention belongs to technical field of image information processing, and in particular to a kind of dust guard of picture processing chip.
Background technology
In recent years, the application of photographing module is more and more extensive, such as mobile phone, computer, monitoring, and the closely related electronics such as take photo by plane
Product, and as these products use increasingly extensive, promote the fast development of image especially photographing module manufacturing industry,
Therefore the stability for improving camera imaging is the trend of current industry development, it is necessary to strictly be managed to the cleannes of inside
Control, in general, picture processing chip is welded on printed circuit board, and printed circuit board easily triggers ash due to static electricity heating
The aggregation of dirt, therefore the dirty point of movement in production on picture processing chip, have a certain impact to the stability of picture quality.
The content of the invention
The invention provides a kind of dust guard of picture processing chip, to solve the dirty point of the movement on picture processing chip
Influence problem to picture quality.
A kind of dust guard of picture processing chip, including dust-proof frame and optical filter, the Filter mosaic is in dust-proof frame
Surface, the dust-proof frame is connected and covers on picture processing chip with printed circuit board.
The operation principle of the present invention：The dust guard of the present invention includes covering the dust-proof frame of picture processing chip and is embedded in
The optical filter that the surface of dust-proof frame completely cuts off dust, by the way that picture processing chip is covered, it is isolated from the environment it and seals,
Prevent external dust pollution image process chip surface；And by the optical filter on dust cover, make to move dust and photosurface
Distance increase, therefore even if dust pollutes the optical filter on dust-proof frame, do not interfere with imaging yet.
Beneficial effects of the present invention：Setting of the invention by dust-proof frame and optical filter, effectively by dust and image
Reason chip isolation is come, and is avoided influence of the mobile dust to picture processing chip, picture quality is maintained higher stabilization
Property.
One of it is preferred that, the bottom of the dust-proof frame is provided with locating piece, and the printed circuit board is provided with and is connected with locating piece
Positioning hole.In order to which dust-proof frame is fixed on a printed circuit board, realized by positioning hole and locating piece.
It is preferred that two, the junction of the dust-proof frame and printed circuit board is provided with fluid sealant.By fluid sealant by dust-proof frame
Connected with printed circuit board, ensure that dust can not enter dust-proof inframe.
Further, the dust-proof frame is made up of plastics, acrylic board or other transparent materials.
Further, the outside of the dust-proof frame is provided with ion blower of the air outlet towards printed circuit board.Printed circuit board
The reason for easily producing dust is that have electrostatic, it is therefore desirable to eliminates electrostatic, ion blower, which can produce, largely carries positive and negative charge
Air-flow, the charging neutrality of institute's band on object can be fallen, when body surface institute band be negative electrical charge when, it can attract in air-flow
Positive charge, when body surface institute band is positive charge, it can attract the negative electrical charge in air-flow, so that the electrostatic on body surface
It is neutralized, reaches the purpose for eliminating electrostatic.
Further, the outside of the dust-proof frame is provided with humidifier.By the way that the humidity of environment is improved, and eliminate electrostatic
A kind of mode, certain humidity also should not be too big.
Further, the optical filter surface is provided with dustproof membrane, and the wavelength of the optical filter has a variety of.Dustproof membrane isolation ash
Dirt, the optical filter that required different wave length designs different size can be directed to.
