Description
Technical field
Security monitoring technology is the utility model is related to, is especially switched with the dust-proof double optical filterings of optical filter edging
Device.
Background technology
Under normal conditions, camera lens module includes camera lens, microscope base, double optical-filter switchers, drive circuit and sensitive chip.Mirror
The main function of head is exactly to filter off black light, allows visible ray to enter, and project on sensor.
The double optical-filter switchers of IR-CUT be by：Optical filter+power section is formed.The original of the double optical-filter switchers of IR-CUT
Reason is by one piece of circuit control panel and switch, and when the light on daytime is abundant, circuit control panel, which is driven in switch, to be switched
Work to cutoff filter, switch restores true color, and when night insufficient light, cutoff filter is automatic
Remove, full spectrum light glass is started to work, and can be sensed the auxiliary light of evening infrared lamp, switch is made full use of all light
Line, so that substantially increasing the low of thermal camera shines performance, whole picture clear and natural.
The existing optical filter of switch on the market uses glass material, and easily to produce scaling-off or chip etc. dirty for glass
Dirt is fallen on sensitive chip.
Utility model content
The purpose of this utility model is to provide with the dust-proof double optical filtering switch of optical filter edging, glass of color filter into
The processing of row edging, prevents its scaling-off and chip produced from falling into sensitive chip, influences to be imaged.Based on the purpose, the utility model
The technical solution of use is as follows：
With the dust-proof double optical filtering switch of optical filter edging, including switch upper cover, switch base, arranged on switch
Light hole on base, optical filter, the filter plate carrier of accommodating optical filter, power set；The inner cavity of switch base is equipped with filter
Mating plate carrier supported bar, the optical filter are fixed on filter plate carrier, and the optical filter reverse side carries out edging processing.Glass is given birth to
The edge of glass also irregularly, after glass edging has following benefit than sharp after production cutting：It is sharp caused by when grinding off cutting
Corner angle, prevent from hurting sb.'s feelings when using；Glass edge because the small gap and micro-crack of cutting formation are ground off, concentrate by local stress relieving
Phenomenon, increases strength of glass；Small gap is avoided to fall glass dregs.In the utility model, optical filter reverse side (is bonded with filter plate carrier
Face (four sides)) edging is carried out, prevent the glass chip on optical filter from dropping on sensitive chip.
Further, the tow sides of the optical filter all carry out edging processing.Glass of color filter tow sides all carry out
Edging, adds the intensity of glass of color filter, while more efficiently prevents from the problem of glass is scaling-off, in optical filter handoff procedure
The glass dregs that optical filter front produces fall on sensitive chip.
Further, the filter plate carrier is equipped with hook, and optical filter is fastened on filter plate carrier by hook.Filter
Mating plate carrier be used for carry optical filter, optical filter use glass material, and carrier can use plastic cement or alloy material, replacement or
When person safeguards optical filter, hook disassembly and assembly easy to connect.
Further, the filter plate carrier support bar is two, is arc-shaped；It is included close to light hole first
Stay, and second support bar opposite with the first support bar, the both ends of first support bar are close to the left and right of switch base
Edge.The shape track of filter plate carrier support bar and the appearance and size of filter plate carrier are engaged, power set driving optical filter
When carrier moves, the edge of filter plate carrier is all the time on filter plate carrier support bar.Support bar plays support filter plate carrier
Effect and serve as filter plate carrier tracks effect.
Further, switch base one end opposite with filter plate carrier support bar is equipped with power set accommodating cavity
Room.The power set of switch are placed by power chamber resettling, and function division is obvious, opposite to form an enclosure space, to power
Device forms protection, while enhances the intensity of switch base so that switch is unlikely to deform, it is ensured that imaging precision.
Further, the cross section of the power set chamber resettling is rectangle, its outer ledge is provided with " L " type
Supporting rib.Switch chamber resettling relative area is bigger, when wall ratio is relatively thin, the bad phenomenon such as easily produces fracture,
The especially on the corner place of stress concentration, it is easier to occur bad, " L " type supporting rib is set, strengthens chamber resettling
The indoor power set of accommodating cavity are had preferably protective effect by intensity.
Further, the both sides of the edge of the switch base are equipped with positioning rib.Switch assemble when, switch base and
No-float between upper cover, hole position align, and just can ensure that switch upper cover and assembling in place, avoid unbalance stress, on switch
Gap is produced between lid and bottom seat, dust enters, and positioning rib effectively positions the upper cover for being caught in switch base, avoids
Assemble bad.
Further, the both sides of the switch base are equipped with pillar, and the both sides of corresponding pillar are equipped with ear.Switch bottom
Through hole is equipped with the pillar of seat both sides, screw thread is equipped with hole, switch upper cover and switch base is connected by screw,
The side of pillar is equipped with ear, enhances the intensity of pillar, when avoiding screw locking, overexerts so that pillar splits.
The beneficial effect that the utility model obtains is：(1) by carrying out edging processing to glass of color filter, glass is enhanced
Intensity, prevents the dirty sensitive chips that directly drop such as the scaling-off and chip of glass generation, causes image bad；
(2) glass of color filter need not be handled in production with regard to edging processing when switch assembles, simple in structure, production system
Make conveniently, it is of low cost, it is adapted to high-volume to promote.
