In order to reach above-mentioned purpose, the utility model discloses a light filter auto-change over device, including the filter case, the front end of filter case be equipped with the light trap, the sensitization case is connected at the rear portion of filter case, upper portion between the wall of filter case both sides is connected with the pivot, the pivot on be fixed with the filter part, pivot one end is equipped with driven gear, driven gear and driving gear meshing, driving gear connection on driving motor's output shaft. The structure is characterized in that the rotating shaft vertical to the light inlet line is used for driving the light filter to turn over, so that the switching effect is realized.
The optical filter component comprises an optical filter frame and an optical filter arranged in the optical filter frame, the upper side of the optical filter frame is fixed with the rotating shaft, a magnet is arranged on one side, close to the photosensitive box, of the lower side of the optical filter frame, a magnetic suction device is arranged on the inner side of the upper bottom surface of the optical filter box, and the position of the magnetic suction device corresponds to the position of the magnet when the optical filter frame is driven to be in a horizontal state by the rotating shaft. The magnet can ensure that the optical filter does not fall down after being turned up in place, thereby releasing the output of the motor.
The further scheme is that the magnets comprise a first magnet and a second magnet, the magnetic attraction device on the inner side of the upper bottom surface of the optical filter box corresponds to the first magnet, meanwhile, a Hall switch corresponding to the second magnet is further arranged on the inner side of the upper bottom surface of the optical filter box, and the Hall switch is electrically connected with the driving motor. And after the Hall switch determines that the optical filter turns upwards in place, the drive motor is controlled to be powered off.
The further proposal is that the magnetic attraction device is an electromagnet, and the Hall switch is electrically connected with the electromagnet. The electromagnet can control the magnetic force more conveniently, so that the adsorption, fixation and release of the optical filter can be accurately selected, and the electromagnet can be linked with the Hall switch.
In a further scheme, the first magnet and the second magnet are respectively arranged on two sides of the filter frame, which are close to one surface of the photosensitive box. Two sides are respectively arranged on the two magnets, the functions of the two magnets are distinguished, and the electromagnet and the Hall switch are released simultaneously, so that the Hall switch can detect the state more accurately.
The utility model discloses a light filter auto-change over device realizes turning of light filter through the pivot structure to utilize magnetic force to adsorb, the light filter under the fixed upset state has released the output of motor. Meanwhile, a detection device in a turnover state is further arranged, and the motor and the electromagnet are simultaneously controlled through the detection device, so that automatic control is performed. The optical filter switching device has the characteristics of reasonable structural design, small volume and high automation control degree.
