And it relates to a wall-mounted mobile probe using the same.

In general, in the conventional adhesive structure, a wet adhesive tape using an adhesive material is mainly used. For example, there are transparent tapes manufactured by Scotch. When the transparent tape is attached to glass or the like, the adhesion is excellent, but it is difficult to reuse, and there is a problem in that the adhesive material falls on the glass together and becomes dirty. In addition, there was a problem that it is impossible to control the adhesive force of the tape.

In addition, as a result of the sole structure of the conventional lizard, there have been many studies on dry adhesives, and there have been dry adhesives using nanocarbon tubes and dry adhesives using polymer nanofibers. These techniques make use of Van der waals force between a myriad of fine fibers and their attached objects, making them difficult to manufacture and attaching them with great vertical force on nanotubes or nanofibers. In addition, it was very difficult to control the adhesive force because there was no directivity.

In addition, the adhesive structure using the carbon nanotubes had a problem that can not be reused because the fiber can not maintain the shape after applying the vertical force to the nanofibers.

The present invention has been made to solve the above problems, it is possible to adhere regardless of the state of the contact surface, that is, the presence or absence of the hole, the material of the contact surface, the adhesive surface, detachable without damaging the product to be bonded Its purpose is to provide an adhesive structure that is capable of repeating use and control of adhesion.

In addition, an object of the present invention is to provide a mobile device that can ride a wall regardless of the material of the wall by using an electrical bonding structure.

On the other hand, according to another aspect of the present invention for achieving the above object, the insulator base of the flexible material, a conductor formed in a pattern in which the anode and the cathode cross on the insulator base, and are respectively connected to both ends of the conductor An electrostatic adhesive pad comprising a positive electrode and a negative electrode; An endless track coupled to the conductive wire forming surface of the electrostatic adhesive pad; A drive and driven gear installed inside the track to drive the crawler; A support bracket installed to connect the motor for driving the drive gear, the shaft of the drive gear, and the shaft of the driven gear with each other to maintain a distance therebetween; Wall-mounted mobile probe is provided comprising a camera installed in the housing surrounding the support bracket and the motor.

Since the electrostatic adhesive pad of the present invention has an adhesiveness irrespective of a material by using static electricity, it can be attached to a wall regardless of the material of the wall such as wood, brick, glass, steel, concrete, and the like. Mobile devices and mobile probes can be attached and moved regardless of the wall material.

Example 1

1 is a conceptual diagram illustrating the principle of the electric force applied to the present invention, Figure 2 is a conceptual diagram illustrating the electric force generated between the electrostatic adhesive pad and the wall of the present invention, Figure 3 is a static adhesive pad of the present invention It is a block diagram.

Referring to these drawings, the electrostatic adhesive pad 1 of the present invention includes an insulator base 100 made of a flexible material, conductive wires 101a and 101b formed in a predetermined pattern inside the insulator base 100, and It comprises a positive electrode and a negative electrode connected to both ends of the conductive wire (101a) (101b), respectively.

At this time, the conductive wires 101a and 101b are composed of a + conductor 101a connected to an anode and a -conductor 101b connected to a cathode, and the conductive wires 101a and 101b have a static electricity in a large area. While generating the inside of the insulator base 100, the + conductor (101a) and the-conductor (101b) is formed alternately and alternately alternately.

The insulator base 100 is made of an insulating material such as an oil paper or a polymer, and the conductive wires 101a and 101b are made by MEMS (Micro-Electro-Mechanical Systems) processing or are electrically conductive. It is preferably made of a tape, the pattern of the conductive wire (101a) (101b) is preferably sealed in the insulator base 100 so as not to be exposed to the outside.

That is, the electrostatic adhesive pad 1 of the present invention constitutes a conductive pattern using a conductor on a flexible insulator material, and the conductive patterns 101a and 101b according to the present embodiment have a rod shape at both ends of the left and right sides of the conductive line. + Poles and-poles are respectively connected to the portions of the rods, and the portions forming the poles and the poles are drawn out horizontally from the rod-shaped portion so as to cross each other.

In addition, a high voltage converter (not shown) is connected to the electrostatic adhesive pad 1 of the present invention to boost the voltage input to the conductive wires 101a and 101b to a desired value.

Meanwhile, the conductive pattern may be modified in various forms in addition to those shown in the present embodiment.

The application principle of the electrostatic adhesive pad 1 of the present invention configured as described above is as follows.

The electrostatic adhesive pad 1 of the present invention uses the attraction force and repulsive force of electric force which is a general physics domain, and Coulomb's law expressed by the following equation is applied.

Here, the direction of force is the direction of pushing each other when F is a positive value, and the direction of pulling each other when a negative value. This expression is called Coulomb's law, named after Coulomb, where k is a proportional constant that is determined experimentally and is called a Coulomb constant. Surprisingly, this law is identical in form to the following law of universal gravitation, which acts on objects of mass.

Maximizing q1 (part of the pad made) by using a high voltage converter increases q2 as the charge q1 inside the object increases (the amount of charge increases) and the magnitude of the electric force is proportional to the product of the two. It can be said that it is proportional to the square of.

In addition, it is important to select a material of a pad having a certain insulating effect so that high voltage static electricity (a state in which many of the same poles are stopped due to the high voltage) inside the wall and the copper wire is not discharged. Coulomb's law shows the increase in attraction.

As a result of the electric force generated between the electrostatic adhesive pad 1 and the wall through this, as shown in Figure 2, the pad is attached to the wall. The friction force is generated between the clamp and the wall due to the electrically generated horizontal clamp pressure (P _N ), and the friction constant changes depending on the condition of the wall and the material.

The electrostatic adhesive pad 1 of the present invention serving as the principle may be used by being adhered to the ceiling or the wall. In this case, the state of the contact surface, that is, the presence or absence of holes formed in the ceiling or the wall, the material of the contact surface, and the adhesion surface Adhesion is possible regardless of the state, and detachment is possible without damaging the products to be bonded.

In addition, unlike the conventional tape, the electrostatic adhesive pad 1 of the present invention can be repeatedly used and control of the adhesive force is possible.
