Background technology
In order to use splanchnoscopy intestinal or enteral surface, a kind of endoscope apparatus that comprises a capsule endoscope of general employing, patient gulps down-Yin capsule endoscope, it moves by wriggling passively, by the image on a video camera picked-up enteral surface in being combined in, and the transmitter in being combined in by and in the receptor transmission of body surface.Chinese patent discloses a kind of capsule endoscopic (Granted publication number: CN 201519127 U), it comprises the capsule-type shell, be positioned at the transparency window of outer casing end, be positioned at enclosure and towards the photographic head of transparency window direction, be positioned at the transmitter unit that enclosure links to each other with the photographic head signal of telecommunication, also comprise: control unit, receiving element and at least one Transflective mirror, the Transflective mirror is installed on enclosure transparency window inboard, and its Transflective characteristic is controlled by control unit; Also comprise receiving element, receiving element links to each other with control unit, is used to receive external control signal, and sends to control unit; Also comprise the lighting unit that is controlled by control unit, the setting of its illumination direction is corresponding one by one with each Transflective mirror, make the spatial bright secretly controlled of each Transflective mirror back, the Transflective mirror is plane mirror or curved mirror, lighting unit is white light source or color light source, it is bright secretly adjustable, and photographic head is positioned at capsular end or waist.But this capsule endoscopic, the distance between camera lens and the pick off, in case become mould to fix, distance can't change, and causes the observable field depth of capsule endoscopic to be fixed, and can't produce the capsule of the different depth of field under same model.
The utility model content
This utility model provides a kind of camera lens and installs and focusing mechanism, it mainly is the distance that solves between existing in prior technology encapsulated endoscopic lens head and the pick off, in case becoming mould fixes, distance can't change, cause the observable field depth of capsule endoscopic to be fixed, can't under same model, produce the technical problem of the capsule etc. of the different depth of field.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of camera lens of the present utility model is installed and focusing mechanism, comprise workbench, workbench is connected with column, described workbench is provided with the camera lens placement platform that can put some camera lenses, but the top of camera lens placement platform is provided with the pneumatic-finger of gripping camera lens, is provided with a Jiao Kou in the pneumatic-finger, point Jiao Kou connects point gum machine, pneumatic-finger is fixed on the lifting platform, and lifting platform is movably connected on the column by lowering or hoisting gear, and lowering or hoisting gear, point gum machine, pneumatic-finger connect host computer by line interface.By the pneumatic-finger fixed lens, camera lens and host computer sensor distance are controlled by lowering or hoisting gear, take the fixed range image by capsule, feed back system in host computer, judge whether this image is picture rich in detail, system according to the motion of image control camera lens, forms closed loop control again, and the high precision between realization camera lens and the host computer pick off is apart from control.
As preferably, described lowering or hoisting gear includes the screw mandrel that flexibly connects with lifting platform, and screw mandrel is connected with motor, and motor connects drive circuit board.Motor can drive screw mandrel and be rotated, thereby lifting platform can move up and down on column, thereby camera lens can be focused.
As preferably, described camera lens placement platform bottom is fixed on the sliding platform, and the sliding platform both sides slidely connect roller, and roller is fixed on the workbench.
As preferably, described lifting platform is provided with electromagnetic valve, and electromagnetic valve connects drive circuit board by circuit.Electromagnetic valve is controlled by numerical control device, can be so that lifting platform autostop when being in certain altitude is controlled comparatively accurate.
Therefore, this utility model can accurately make capsule lens be positioned over accurate position, and the realization capsule can be taken the different distance image, this utility model is the collection capsule lens, installation, adjustment, focusing, fixing, incorporate electromechanical integration equipment, enhance productivity, simple and reasonable for structure.
