100231 The cleaning unit is combined with the electrostatic adsorption effect of the copper rod-shaped electrodes 4; and the moving unit drives the lead screw 8 through the stepping motor 12 to drive the guide rail sliding blocks 2 and the copper bar-shaped electrodes 4 to move.
100241 The moving unit of the device is located on the back face of the optical glass. The optical glass can be cleaned under the condition that the optical glass is not detached. The cleanable range can be changed by adjusting the lengths of the copper rod-shaped electrodes 4 and the lead screw 8, so that the application is flexible. According to the specific installation mode, the device is installed in an optical system. Then, the optical glass is arranged on the lens frames 15 of the device and fixed through the lens clamping pieces 14. The device is started when a certain piece of optical glass needs to be cleaned, and the device aims at the horizontally placed optical glass.
100251 In the second specific embodiment, according to the device utilizing a movable electrostatic electric field to attract particulate pollutants in the first specific embodiment, the process parameters when the device works are as follows: the electrostatic voltage is 7 kV, the distance between the two copper rod-shaped electrodes 4 located above and below the optical glass 1 is 30 mm, and the speed of the copper rod-shaped electrode is 10 mm/s 100261 In the third specific embodiment, according to the device utilizing a movable electrostatic electric field to attract particulate pollutants in the first specific embodiment, the nylon tank 5 is a rectangular tank, and holes are formed in two end plates of the nylon tank 5 at equal intervals.

100291 A specific using method of the device is described in combination with FIG. 1. In the device, the copper rod-shaped electrodes 4 are controlled by the stepping motor 12 to scan on the surface of the optical glass 1, so that the device can be applied to the optical glass 1 with various areas, the occupied volume is small, and the dust removal efficiency is high. The copper rod-shaped electrodes 4 are arranged on the upper portion and the lower portion of the optical glass 1 respectively. The optical glass 1 is fixed through the lens clamping pieces 14 and the lens frames 15. The lens is dismounted exceptionally, and the device, together with the lens, is directly installed in the optical system, namely the device is equal to an optical lens seat with a cleaning function.
100301 The device comprises a base unit, a moving unit and a control unit. The base unit provides support for the moving unit. Static electricity removal only has a cleaning effect on the surface of the optical glass 1 between the copper rod-shaped electrodes 4, and therefore, the cleaning range is determined by the movement range of the copper rod-shaped electrodes 4. Here, the lead screw 8 with the movement travel of 400 mm and the lead of 4 mm is selected as a core assembly of the moving unit, and direct drive of the stepping motor 12 is adopted as a power source. In order to control the stepping motor 12, a proper driving and control system needs to be selected for the stepping motor 12. The limit switches 13 are additionally arranged in the device to limit the stepping motor 12, so that the situation that when the copper rod-shaped electrodes 4 are powered by a high-voltage power supply, the movement range exceeds the limit to cause danger is avoided.
100311 The copper bar-shaped electrodes 4 are installed on the nylon tank 5. The nylon tank 5 is provided with round holes at equal intervals and marked with scales. The distance between the copper bar-shaped electrodes 4 is controlled by installing the copper bar-shaped electrodes 4 at different round holes in the nylon tank 5. Meanwhile, the copper bar-shaped electrodes 4 are insulated from other components due to the fact that nylon material is high in insulation capacity. The nylon tank 5 is fixed on the strip-shaped steel plate 6, and the strip-shaped steel plate 6 for fixing the nylon tank 5 is also responsible for connecting the lead screw 8, the nut seat 16 and the guide rail sliding blocks 2 together. Through the design, thrust on the lead screw 8 is prevented from acting on the copper bar-shaped electrodes 4, so that the straightness of the copper bar-shaped electrodes 4 is guaranteed. The uniformity of electric field distribution between the copper bar-shaped electrodes 4 can be guaranteed only by guaranteeing the straightness of the copper bar-shaped electrodes 4. The overall power is provided by the stepping motor 12, and the stepping motor 12 is connected with the lead screw 8 through the elastic coupler 11. The diameter of the copper rod-shaped electrode 4 is 12 mm.
100321 The stepping motor 12 is a Model 42 stepping motor with a step angle of 1.80 so that the maximum torque of 0.4 Nm can be provided, and the output shaft is a D-type shaft with the maximum diameter of 5 mm. Compared with a circular shaft, the D-type shaft has lower requirements on the coupler 11 under the condition that the output torque is guaranteed. The TB6600 type driver is selected as a driver of the stepping motor and can provide current with the maximum of 4 A, and the maximum current can be set to be 32 times of subdivision. The more subdivision is, the more stable the movement of the stepping motor is, and the lower the rotating speed is when the output clock frequency of the controller is the same. The DKC-1B type controller is selected as the controller of the stepping motor. As an industrial-grade controller, the DKC-1B type controller can still keep high reliability and stability under the interference of strong electromagnetism and dust of experiments.
100331 The Taiwan MeanWell switching power supply is selected as the low-voltage power supply with the model of NES-100-24, the output voltage of 24V and the maximum output current of 4.5 A, and the use requirements of the device can be met. In the aspect of travel control, a proximity switch is selected as the limit switch 13. Compared with a conventional mechanical pressing type sensor, the proximity switch does not need direct physical contact, so that signal interference caused by contact between a high-voltage clean system and a low-voltage signal system is avoided, and the reliability of the device is enhanced.
100341 The CX-150A type high-voltage power supply is selected as the high-voltage power supply, and the voltage output of the high-voltage power supply is adjustable. When the input voltage is 220 V, the highest output voltage of the high-voltage power supply can reach 15 kV, and the requirement of the device for the voltage is met. In the aspect of safety, the device has an ignition protection function and a short-circuit protection function, so that the safety of personnel and the device can be well guaranteed. The copper rod-shaped electrode in the device is a red copper electrode, and the copper rod-shaped electrode is high in conductivity and stable in chemical property. 100351 In order to verify the adsorption effect of the device, Si02 particulate micro-powder is adopted to simulate actual particulate pollutants, and the diameter of the Si02 particulate micro-powder is changed from 5 gm to 100 pm. The verification result shows that the strength of the electric field generated by the device on the surface of the optical element is also increased along with the increase of the electrostatic voltage, so that the adsorption efficiency is increased along with the increase of the voltage. The positions of the copper bar-shaped electrodes are also of great influence on the adsorption efficiency. The closer the copper bar-shaped electrode is to the optical element, the higher the local electric field is easily generated, so that the adsorption efficiency is increased. However, the distance between the copper rod-shaped electrode and the element is too small, arc discharge is easily caused, and the adsorption efficiency is reduced. Through many times of experimental optimization, reasonable technological parameters of the experimental device are finally obtained: when the electrostatic voltage is 7 kV, the distance between the upper copper rod-shaped electrode and the lower copper rod-shaped electrode 4 of the optical glass 1 is 30 mm, and the speed of the copper rod-shaped electrodes is 10 mm/s, the adsorption efficiency of particulate pollutants of more than 20 pm can reach 80%.
