Abstract
The utility model provides an exposure camera lens protection architecture, it includes the lens cone, bottom lens passes through the optical cement and fixes at the lens cone inner wall in the lens cone, the lens lower extreme is provided with protection glass, protection glass and lens cone inner wall seamless connection, protection glass below still is equipped with a plurality of vent structure, vent structure is in the lens cone protection glass below produces decurrent air current. The utility model provides a protective glass head can completely cut off the exposure camera lens and volatilize printing ink organic gas direct contact, and the protection glass who provides simultaneously can dismantle alone, the convenient change, and the image quality to the exposure camera lens does not exert an influence, protect protection glass lower surface through compression filtered air simultaneously.
Description
Technical field
The utility model relates to PCB litho machine field, particularly relates in PCB industry for the operator guards to exposure cameras.
Background technology
Projective lens is the core component of PCB litho machine, and projective lens needs to consider dust protection in the design process, and anti-volatile organic compounds enters.
Anti-solder ink is PCB indispensable part in PCB manufactures.But ink has volatility, and belong to organic gas, in exposure process, the ink of volatilization will inevitably produce exposure cameras and pollute, and affects the quality of exposure cameras, even causes exposure cameras to use, so that scrap.
Utility model content
The utility model provides a kind of exposure cameras operator guards; it comprises lens barrel; in described lens barrel, lowermost end eyeglass is fixed on lens barrel inwall by optical cement; described eyeglass lower end is provided with cover glass; described cover glass and the seamless link of lens barrel inwall; also be provided with some ventilation devices below described cover glass, described ventilation device produces downward air-flow below described cover glass in lens barrel.
Preferably, described ventilation device comprises the blow vent on described lens barrel surface and the snorkel be located in described air hole, and described venting tube outlet is positioned at described lens barrel and arranges down.
Preferably, described air hole and snorkel quantity are multiple, and the described ventilation mouth of pipe is located at the below at described cover glass edge.
Preferably, the air that described snorkel passes into passes through the pressurized air not containing organic gas of purification.
Preferably, its lower end of described cover glass is connected with trim ring, and described cover glass is connected with described lens barrel by trim ring.
Preferably, described trim ring is connected with described camera lens by screw thread.
The utility model has following beneficial effect:
The len that the utility model provides can completely cut off exposure cameras and directly contact with volatilization ink organic gas, and the cover glass simultaneously provided can be dismantled separately, is convenient for changing, and does not have an impact to the image quality of exposure cameras; By compressed air filtering, cover glass lower surface is protected simultaneously.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described describing the required accompanying drawing used to embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The exposure cameras operator guards schematic diagram that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of exposure cameras operator guards; it comprises lens barrel 2; in lens barrel 2, lowermost end eyeglass 1 is fixed on lens barrel 2 inwall by optical cement; eyeglass 1 lower end is provided with cover glass 5; cover glass 5 and the seamless link of lens barrel 2 inwall; also be provided with some ventilation devices below cover glass 5, described ventilation device produces downward air-flow below cover glass 5 in lens barrel 2.
Wherein said ventilation device comprises the blow vent on lens barrel 2 surface and the snorkel 4 be located in described air hole, and snorkel 4 outlet is positioned at lens barrel 2 and arranges down.
Described air hole and snorkel 4 quantity are multiple, and the mouth of pipe of snorkel 4 is located at the below at cover glass 5 edge.
The air that snorkel 4 passes into is through the pressurized air not containing organic gas of purification.
Its lower end of cover glass 5 is connected with trim ring 3, and cover glass 5 is connected with lens barrel 2 by trim ring 3, and trim ring 3 is connected with lens barrel 2 by screw thread.The cover glass 5 that the utility model provides can by trim ring 3 dismounting and change separately.
The len that the utility model provides can completely cut off exposure cameras and directly contact with volatilization ink organic gas, and the cover glass simultaneously provided can be dismantled separately, is convenient for changing, and does not have an impact to the image quality of exposure cameras; By compressed air filtering, cover glass lower surface is protected simultaneously.
Disclosed the utility model preferred embodiment just sets forth the utility model for helping above.Preferred embodiment does not have all details of detailed descriptionthe, does not limit the embodiment that this utility model is only described yet.Obviously, according to the content of this instructions, can make many modifications and variations.This instructions is chosen and is specifically described these embodiments, is to explain principle of the present utility model and practical application better, thus makes art technician understand well and to utilize the utility model.The utility model is only subject to the restriction of claims and four corner and equivalent.
