For fixing described burnt lamp box far away and nearly burnt lamp box, and regulate the kinematic train of described burnt lamp box far away and nearly burnt lamp box position.
According to quickcam image focusing testing tool of the present utility model, described quickcam image focusing testing tool is fixed on a base by a guide pillar.
According to quickcam image focusing testing tool of the present utility model, the burnt mirror of described increasing is screwed with described nearly burnt lamp box after being installed in and increasing in burnt picture frame.
According to quickcam image focusing testing tool of the present utility model, described quickcam image focusing testing tool also comprises-is arranged at the adjustable lock dog of described guide pillar, described adjustable lock dog can be up and down in described guide pillar, and described nearly burnt lamp box and the burnt picture frame of increasing are arranged at described adjustable lock dog.
According to quickcam image focusing testing tool of the present utility model, described kinematic train comprises the screw mandrel of being located in described guide pillar, and the handwheel being connected with described screw mandrel, and described burnt lamp box far away is arranged at described screw mandrel.
The utility model is by being provided for regulating the far away burnt lamp box of test burnt sharpness far away in the focusing process of described camera at quickcam image focusing testing tool, make it have the burnt test function that regulates far away, and nearly burnt lamp box is set, can test the near burnt adjusting of described camera, dirty dust detection and dark angle.Further, be also provided with and increase burnt mirror for extending the focal length of described camera and amplifying focusing drawing; And for fixing described burnt lamp box far away and nearly burnt lamp box, and regulate the kinematic train of described burnt lamp box far away and nearly burnt lamp box position.Whereby, the utility model has increased nearly burnt test function; Reduce focusing drawing height, solve the problem of workshop quickcam image focusing insufficient height; Dwindle focusing drawing area, dwindle quickcam image focusing test station area, save more productions space; Improve current conventional lightbank homogeneity and serviceable life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the quickcam image focusing testing tool of the utility model one embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, the utility model provides a kind of quickcam image focusing testing tool, and it comprises burnt lamp box 3 far away, nearly burnt lamp box 4, increases burnt mirror 9 and kinematic train four major parts, concrete:
Burnt lamp box 3 far away is comprised of lamp door, LED even lamp source and related circuit, is mainly used in burnt sharpness far away in quickcam image focusing process and regulates test.
Nearly burnt lamp box 4 is comprised of lamp door, LED even lamp source and related circuit, is mainly used in the nearly burnt adjusting of camera, the dirty dust detection of camera and dark angle and detects.
Increase 9, burnt mirror and formed by two optical lens gummeds, for extending camera focal length, amplify focusing drawing.
Kinematic train is comprised of rotary handle 1, screw mandrel (not shown) and guide pillar 2.Kinematic train is mainly used in fixing burnt lamp box 3 far away and nearly burnt lamp box 4, and regulates the height of burnt lamp box 3 far away and nearly burnt lamp box 4.Increasing burnt mirror 9 packs in the burnt picture frame 5 of increasing and is screwed with nearly burnt lamp box 4.
The 5000000 pixel camera head focusing of take below the present embodiment are example explanation.
Concrete debug process is as follows: by adjusting lock dog 7, the burnt picture frame 5 of increasing is adjusted to a proper height locking, this height is operating as well suitable with focusing staff's hand.Camera is placed and increased burnt picture frame 5 times, the burnt mirror 9 of increasing is put into and increased burnt picture frame 5, actual focusing requirement for height is 2.5 meters, and after use increases burnt mirror, corresponding Jiao far away highly reduces to 38 centimetres, and namely burnt lamp box 3 far away should be adjusted to burnt picture frame 5 top 38 centimeters of distance increasing.By handwheel 1, adjusted after the height of burnt lamp box 3 far away, staff can start focusing until camera is adjusted to clear Jiao far away.Far Jiao keeps camera position constant after debugging, and nearly burnt light box 4 carries out nearly burnt test with secretly angle, dirty point are tested above rotating to camera by bearing 8 on surface level.Complete after burnt debugging far away, nearly burnt debugging, dark angle and dirty test, can take off camera and change next camera and test.
The utlity model has following beneficial effect:
1) nearly burnt lamp box 4 has solved existing product does not in process of production have the nearly burnt problem of test.
2) burnt lamp box 3 far away has solved in current production run the not high and not long problem of life-span of light homogeneity.What traditional far away burnt lamp box was selected is that fluorescent tube is as light source, in use procedure, homogeneity only has 70% left and right, and be 6000-10000 hour serviceable life, this tester improves and uses LED as lamp source, homogeneity is greater than 90%, and be 30000-50000 hour serviceable life, compares the fluorescent light of existing use, the LED lamp that this instrument uses has improved 20% in homogeneity, life 5 times.
3) save production space.In tradition focusing method of testing, current five mega pixels and above quickcam image focusing burnt target size far away are long 142 centimetres wide 80 centimetres, and this tester is with long 60 centimetres wide 40 centimetres of burnt lamp box far away, saves 75% production test space.A required production space of tradition focusing station can arrange four focusing stations after using this instrument.
4) reduce the height of burnt lamp box far away.In high pixel focusing process, traditional far away burnt lamp box is apart from the requirement for height of camera at 2～5 meters, and in actual production process, workshop height cannot meet this requirement.Increase burnt mirror and can extend camera focal length, can, by corresponding the narrowing down between 30～50 centimetres of focussing distance between focusing drawing and camera, in production run, can be easy to just realize high pixel focusing.
In sum, the utility model is by being provided for regulating the far away burnt lamp box of test burnt sharpness far away in the focusing process of described camera at quickcam image focusing testing tool, make it have the burnt test function that regulates far away, and nearly burnt lamp box is set, can test the near burnt adjusting of described camera, dirty dust detection and dark angle.Further, be also provided with and increase burnt mirror for extending the focal length of described camera and amplifying focusing drawing; And for fixing described burnt lamp box far away and nearly burnt lamp box, and regulate the kinematic train of described burnt lamp box far away and nearly burnt lamp box position.Whereby, the utility model has increased nearly burnt test function; Reduce focusing drawing height, solve the problem of workshop quickcam image focusing insufficient height; Dwindle focusing drawing area, dwindle quickcam image focusing test station area, save more productions space; Improve current conventional lightbank homogeneity and serviceable life.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
