Embodiment
Below by drawings and Examples, the technical solution of the utility model is done detailed description further.
Fig. 2 be the utility model cleaning device specific embodiment structural representation, as shown in Figure 2, the utility model cleaning device comprises support 1, be used to batch the turning axle 2 of friction cloth, be fixed on the support 1, be used to utilize the electrostatic rod 5 of fiber-like particle on the Electrostatic Absorption friction cloth, be fixed on the support 1.A light source chamber that sends special light 3 that provides camera 4 to take pictures usefulness also is provided this cleaning device, it can be the fluorescent tube of LED class, sending white high light is beneficial to camera 4 and photographs tiny fiber-like particle, the diameter of electrostatic rod 5 is 7-15mm, the space that takies cleaning device is considerably less, the voltage of electrostatic rod 5 is 500-1000V, distance with friction cloth during electrostatic rod 5 absorption friction cloth remains 3-10mm, both guaranteed that exoelectrical reaction did not take place other hardware on electrostatic rod 5 and the cleaning device, and can guarantee effectively to adsorb the fiber-like particle on the friction cloth again.The rotational speed of turning axle 2 is a 0.5-5 cycle per minute clock, can make friction cloth can not be rotated axle 2 and tear badly, can make electrostatic rod 5 that time enough and friction cloth generation suction-operated are arranged again.
Fig. 3 is the side-looking structural representation of electrostatic rod in the utility model cleaning device specific embodiment, as shown in Figure 3, electrostatic rod 5 is fixedly mounted on the support bar 6, support bar 6 is fixedly mounted on the connection bearing 8, connection bearing 8 is connected with support 1 and can rotates around self axle center, positioning disk 7 fixed covers are located on the connection bearing 8, during rotational positioning dish 7, to drive support bar 6 and connection bearing 8 rotates simultaneously, thereby the position of the electrostatic rod 5 that is fixedly connected on the support bar 6 is moved, also be provided with working position socket 10 and cleaning position socket 11 on the positioning disk 7, be used to assign register pin 9, register pin 9 is fixedly mounted on the register pin 9 on the support 1.When the fiber-like particle on the needs absorption friction cloth, working position socket 10 on the positioning disk 7 is rotated to register pin 9 places, make electrostatic rod 5 near the friction cloth on the turning axle 2, distance remains 3-10mm and is beneficial to adsorb fiber-like particle on the friction cloth, when electrostatic rod 5 needs cleaning, cut off the power supply of electrostatic rod 5 and the cleaning position socket 11 on the positioning disk 7 is rotated to register pin 9 places, electrostatic rod 5 is polluted avoiding away from turning axle 2, to be adsorbed with electrostatic rod 5 wiped clean of fiber-like particle then, process is very simple, is convenient to operation.
The course of work of the utility model cleaning device is specially: open cleaning device, friction cloth to be detected is placed on the turning axle 2, working position socket 10 on the positioning disk 7 is rotated to register pin 9 places, make electrostatic rod 5 near turning axle 2, and turning axle 2 is rotated, electrostatic rod 5 chargings, light source chamber 3 is luminous, turning axle 2 can drive the rotation of friction cloth, the Coulomb force of electrostatic rod 2 of charging adsorbs the fiber-like particle near the friction cloth that rotates to the electrostatic rod 5, zone after friction cloth is adsorbed by electrostatic rod 5 can be rotated to the picture taking interval of camera 4 subsequently, under the irradiation of special light that light source chamber 3 sends such as white high light, taken pictures, photo with the cloth that rubbed clearly, like this, the whole surface of friction cloth will be cleaned one time by the absorption of the statcoulomb power of electrostatic rod 5 along with the rotation of turning axle 2, while is also taken pictures, draw on the friction cloth by the also residual fiber-like number of particles in electrostatic rod 5 absorption back and the position at place according to the image of friction cloth, can mark and exceed scope that technology allows on the friction cloth and the defective region of the fiber-like particle that needs clean.Under the suction-operated of the statcoulomb power of electrostatic rod 5, the fiber-like particle of the overwhelming majority will be removed totally on the friction cloth, the minority fiber-like particle of not getting rid of can continue to come adsorption removal by cleaning device, minority is difficult to be adsorbed the fiber-like particle that falls by the statcoulomb power of electrostatic rod 5 and can removes with tweezers again, so not only saved the time, improved production efficiency, and greatly reduced the chance of using tweezers, reduced friction cloth by the probability of scratch.
The electrostatic rod 5 that is adsorbed with the fiber-like particle is cut off power supply, cleaning position socket 11 on the positioning disk 7 is rotated to register pin 9 places, make electrostatic rod 5, utilize cleaning cloth that the fiber-like particle above the electrostatic rod 5 is wiped out away from turning axle 2, just can reuse, very simple and convenient.
In sum, the utility model cleaning device only need just can be removed fiber-like particle on the cloth that rubs expeditiously in that an electrostatic rod is installed on original cleaning device, utilized original cleaning equipment to greatest extent, simple in structure, cost is low, and is easy to operate.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
