Seal but the middle through hole of printing opacity, it is possible to effectively prevent external dust from entering photographic head internal imaging region, thoroughly stop dust interference,
Therefore, not havinging after client uses a period of time instrument, the dust of generation drops to above sensitive chip, on the image of display
The situation of stain occurs；And the sensitive chip sealing of detector is good, does not results in and dry during producing or transporting
Clean sensitive chip again pollutes and causes and do over again；Without being cleaned sensitive chip after installation, it is the most unnecessary to eliminate
Operating process, save manpower and man-hour, production efficiency is high.
Described dust cover main body is fixed in PCB substrate by this utility model by being screwed in bolt collar through aperture by bolt,
Therefore, if other elements in the PCB substrate in sensitive chip or dust cover are keeped in repair, can directly by
Bolt is turned on, and dust cover main body is dismantled, and can keep in repair.Lens barrel, dust cover pedestal and bolt collar are plastics
Material, insulating properties is good and low cost.
The connected mode of this utility model optical filter also has multiple.One is directly by glue, optical filter to be pasted onto described lens barrel
The mode of upper end, simple to operation；Provide again in the groove of a kind of upper end inwall that optical filter is embedded in lens barrel, optical filter
Interference fit, therefore, even if even turning upside down PCB substrate in transportation, optical filter is formed with the upper end inwall of lens barrel
Also will not move and even drop out, the inner sealing of dust cover main body is good, and protection is filtered by the embedded structure of optical filter
Sheet is difficult to be worn；This utility model additionally provides and is positioned over by optical filter in lens barrel lid, by being tightened on lens barrel by lens barrel lid
Described optical filter is linked together with lens barrel, the quick detachable maintenance of this mode.
This utility model additionally provides the connected mode of two kinds of lens barrels and dust cover main body.One of which is directly by dust cover pedestal
It is integrated with lens barrel welding, is directly produced out the dust cover of one, installs the easiest；Another is at dust cover pedestal
It is provided with objective lens barrel aperture, lens barrel is connected on dust cover pedestal by screwing, it is also possible to need to regulate the height of lens barrel by actual.
Therefore, the dust guard simple in construction of skin and hair detector of the present utility model, mode is flexible, it is possible to be effectively prevented
External dust enters photographic head internal imaging region, thoroughly stops dust interference, and does not results in secondary producing or transporting
Pollute, clean easy to maintenance, cheap, and improve production efficiency, minimizing is done over again, hence it is evident that improve yield.
