The invention also provides a use method of the dust removal device for the lens, which comprises the following steps:
covering the dust removing device on the lens 20;
turning on the controller 30, the light emitter 50 and the light receiver 51 to monitor whether there is dust on the transparent glass 11; and
when the controller 30 receives the feedback signal sent by the optical receiver 51, the controller 30 controls the operation of the dust scraper 40 to remove dust from the transparent glass 11, and controls the operation of the dust scraper 40 to stop after the dust removal is finished.
The specific principle is as follows: when the transparent glass 11 is clean and dustless, the light emitted obliquely by the light emitter 50 is emitted out of the glass, and the light receiver 51 cannot receive the corresponding light, so that the dust scraper 40 cannot be triggered to start.
When dust exists on the transparent glass 11, the light emitted from the light emitter 50 in an oblique direction is reflected by the transparent glass 11 and then received by the corresponding light receiver 51, and the controller 30 controls the dust scraper 40 to scrape the transparent glass 11.
As a preferred embodiment of the method for using the dust removing device for lens of the present invention, a light intensity limit value is preset in the controller 30; the controller 30 obtains the light intensity value in the feedback signal after receiving the feedback signal sent by the light receiver 51, compares and judges the light intensity value with the light intensity limit value, and controls the dust scraper 40 to operate to remove dust from the transparent glass 11 when judging that the light intensity value is greater than the light intensity limit value.
As a preferred embodiment of the method for using the dust removing device for lens of the present invention, the dust removing device further comprises a fluid delivery mechanism connected to the dust scraper 40; when the dust scraper 40 is operated, the liquid feeding mechanism feeds cleaning liquid to the dust scraper 40 for cleaning the transparent glass 11.
Specifically, the system is powered on to start the controller, the display is lightened, and various preset control parameters are displayed on the display screen. If the parameters need to be changed, the parameters can be changed and stored through setting keys of the display screen.
The light emitter 50 and the light receiver 51 are powered on to work, whether the intensity of the reflected light reaches a set value or not is detected, and if the intensity of the reflected light does not reach the set value, the transparent glass is in a clean state. The optical transmitter 50 and the optical receiver 51 continue the detection cycle all the time. If the set value is reached, the transparent glass is required to be cleaned.
The cleaning signals of the light emitter 50 and the light receiver 51 are sent to the controller. The controller starts the infusion pump, and the infusion pump feeds back parameter values such as flow, pressure and the like to the controller. If the abnormal controller exists, the infusion pump is stopped and an alarm is given; if the controller is abnormal, the motor is started again to drive the scraper blade of the dust scraper to clean the transparent glass.
Specifically, the cleaning time of the dust scraper or the action times of the scraping blade are preset by the controller, and when the cleaning time is up, the controller stops the motor and the infusion pump. When the light emitter 50 and the light receiver 51 which continue to operate detect again that the intensity of the reflected light reaches the set value, the operation of the dust scraper is started by the controller driving the motor and the infusion pump. And pausing to wait for the next round of cleaning when the transparent glass to be cleaned reaches the standard.
The dust removal device for the lens and the using method thereof have the beneficial effects that:
according to the invention, the light emitter is adopted to emit light rays to the transparent glass in front of the lens in an inclined manner, when the transparent glass is clean and dustless, the inclined light rays emitted by the light emitter are emitted out of the glass, the light receiver cannot receive the corresponding light rays, and the intensity of reflected light detected by the light receiver does not reach a set value, so that the controller cannot start the dust scraper according to a feedback signal of the light receiver. When having the dust on transparent glass's surface, through blocking of dust and make the light that the light emitter sent take place the reflection in transparent glass department, and then light receiver receives through the light of reflection and forms feedback signal and send for the controller, the controller scrapes the operation of dirt ware in order to remove dust to transparent glass according to the feedback signal control that receives, realizes automated inspection and clearance, whether glass before solving among the prior art artificial observation camera lens and the camera lens has the spot of polluting takes time and takes a lot of work and can't clean problem.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
