At this time, the mounting bracket part 162 may be formed in the head bracket part 161. Accordingly, the support bearing portion 164 or the mounting bracket portion 165 is inserted and fixed into the mounting groove portion 162. [

As the head bracket 161 is provided, the cleaning head 110 is detachably coupled to the head bracket 161, so that the consumable cleaning head 110 can be easily replaced.

The extension protrusion 163 is engaged with the support bearing portion 164. The extended protruding portion 163 protrudes from the eccentric cam portion 136 of the eccentric portion 133 of the eccentric rotation portion 130. As the extended protrusion 163 is formed, the size of the eccentric cam 136 and the size of the support bearing 164 can be coped with. In other words, even when the size of the eccentric cam portion 136 is different from that of the support bearing portion 164, the eccentric cam portion 136 can be stably coupled to the support bearing portion 164 through the extended protrusion portion 163 Can be fixed.

The fine reciprocating unit 140 adjusts the force applied by the cleaning head unit 110 to the display panel.

The fine reciprocating part 140 includes a fine driving part 141 for generating a driving force by an applied power source and a driving part for driving the fine washing part 130 by a driving force of the fine driving part 141 so that a force applied to the display panel is controlled. (Not shown). The micro-driving unit 141 may be a cylinder, and the micro-connecting unit 142 may be a piston.

Here, the fine reciprocating unit 140 includes a connection joint unit 143 provided on the micro-connection unit 142 to compensate for the shift of the operation center due to the reciprocating movement of the cleaning head unit 110, And a fine bracket part 144 for coupling the driving part 141 to the placement reciprocating part 150 so as to reciprocate. The connecting joint portion 143 may be constructed of various types of floating joints known in the art.

The protective cover unit 170 surrounds the eccentric rotation unit 130 to block foreign substances generated by the cleaning of the display panel. At this time, the protective cover part 170 may be wrapped around one of the rotation axis part 132 and the pin axis part 135 of the eccentric rotation part 130 to reciprocate. It is possible to prevent foreign matter from being transmitted to the respective driving parts along the rotation axis part 132 and the eccentric shaft part 135 through the protective cover part 170 and to prevent the respective driving parts from being malfunctioned by the foreign matter . In particular, the protective cover 170 is formed on the side of the display panel or under the display panel according to the supply form of the display unit, thereby preventing or preventing the transfer of foreign matter.

When the display panel is to be cleaned, the cleaning head unit 110 is brought into contact with the surface of the display panel according to the operation of the placement reciprocating unit 150. At this time, the force applied to the display panel can be adjusted according to the operation of the fine shuttle 140.

When the rotation shaft portion 132 is rotated according to the operation of the eccentric rotation portion 130, the eccentric portion 133 is operated to rotate the eccentric shaft portion 135. At this time, the eccentric shaft portion 135 is rotated so that the eccentric cam portion 136 is rotated about the eccentric shaft portion 135.

However, the eccentric cam portion 136 is coupled to the cleaning head portion 110 via the eccentric supporting portion 160. [ Accordingly, as the eccentric cam portion 136 rotates, the operation of the washing head portion 110 is controlled by the eccentric supporting portion 160.

In other words, the eccentric cam portion 136 is rotated by restricting the cleaning head portion 110 to the eccentric rotation portion 130 by the elastic rod portion 166, (132) or the eccentric shaft portion (135). Here, the radius of the imaginary concentric circle can be known by the amount of eccentricity of the eccentric cam portion 136. [ Then, the center of the cleaning head 110 moves along the virtual concentric circle.

According to the cleaning unit of the display panel and the cleaning apparatus of the display panel provided with the cleaning unit, the cleaning head unit 110, which is prevented from rotation, is moved in a state of being in contact with the plane, thereby simplifying the movement of the display panel, The panel can be cleaned quickly and accurately.

In addition, since the cleaning device is compactly moved and cleaned while moving all the way back, right, and left on the surface of the display panel, the cleaning range through the cleaning head portion 110 is increased and the time and cost required for cleaning the display panel Can be saved.

In addition, the cleaning force of the motion contrast cleaning unit or the cleaning device of the cleaning head unit 110 can be increased.

In addition, since the cleaning of the display panel is in-line, the work process is simplified, the risk factors generated during the cleaning process through the cleaning head unit 110 are prevented in advance to prevent a safety accident, Can be prevented.

The plurality of cleaning heads 110 are disposed on both sides of the display panel so that the process of reversing the display panel is eliminated and the cleaning unit disposed under the display panel can be protected .

Further, it is possible to control the distance between the cleaning head 110 and the display panel, as well as the force that the cleaning head 110 presses the display panel.

In addition, the cleaning area of the cleaning head 110 appears as an ellipse on the surface of the display panel, and the long axis of the ellipse is formed in a direction crossing the moving direction of the display panel, It can be cleaned.

Further, it is possible to increase the coupling force between the driving parts, to transmit the vibration according to the operation of each driving part to the display panel, or to compensate the shift of the working center in the reciprocating movement of the cleaning head part 110.

Further, it is possible to smooth the reciprocating movement of the cleaning head 110 in the cleaning unit, to suppress or prevent the flow according to the operation of each of the driving units, and to smoothly transmit the eccentric rotational force generated in the eccentric rotation unit 130 have.

The eccentric rotation unit 130 and the cleaning head unit 110 are coupled to each other and the operation of the eccentric cam unit 136 eccentrically rotated with respect to the rotary shaft unit 132 is stably performed in the cleaning head unit 110 ). ≪ / RTI >

The eccentric cam unit 136 can suppress or prevent the noise generated when the eccentric cam unit 136 rotates and mitigate the shock applied to the cleaning head unit 110 by rotating the eccentric cam unit 136.

Also, the cleaning head unit 110 can be prevented from rotating by the eccentric rotation unit 130, and the cleaning head unit 110 can be smoothly moved along a virtual concentric circle.

In addition, it is possible to stabilize the movement of the display panel, to prevent the display panel from moving in a direction crossing the moving direction of the display panel by the cleaning unit during the movement of the display panel, Can be prevented.

In addition, it is possible to simplify the collecting process of the foreign substances generated inside the cleaning housing unit 20, and to prevent foreign matter from leaking to the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Modify or modify the Software.
