Description

{DEVICE FOR CONTROLLING THE HORIZONTALITY}

More particularly, the present invention relates to a horizontal holding device, and more particularly, to a vertical holding device for vertically moving three leveling panels by vertically driving three leveling panels, And a horizontal holding device capable of maintaining the horizontal position.

Recently, TOUCH SCREEN PANEL (TSP) technology has been widely used for convenience of user interface. In particular, due to the rapid spread of smart phones (smart phones) and tablet PCs, demand for such touch screen panels is increasing more and more.

1, in a state in which a resin (R) is coated on a glass panel (10) or a film adsorbed on a lower adsorption chuck (30), an upper adsorption chuck 40 and the other glass panel 20 or film is moved up and down while being vertically moved. In this attaching step, it is important to maintain the horizontal state of the glass panel or panel 10 disposed below for attachment. That is, if the glass panel is not maintained in a horizontal state when the resin R is applied on the glass panel 10, the thickness of the resin applied on the panel is not uniform, It is high.

However, since the thickness of the glass panel or the film is not constant, the top surface of the panel may be inclined, and the shape of the film or the glass panel itself may be deformed to fail to maintain a flat state. In this case, a method of correcting the horizontal position of the glass panel or the upper surface of the film by correcting the inclination of the glass panel or the table supporting the film is used.

However, conventionally, when all four corners of the stage are moved in the vertical direction and aligned horizontally, the algorithm for aligning the horizontal is too complicated and the process time is too long for aligning the horizontal.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a leveling panel which can vertically adjust the height of three points while vertically driving the leveling panel by three elevation shafts, And a horizontal holding device provided with the horizontal holding device.

According to an aspect of the present invention, there is provided a horizontal holding apparatus comprising: a leveling panel having a plate structure; Three elevation shafts installed at three different points on the lower surface of the leveling panel and independently elevating and lowering respective points of the leveling panel in the vertical direction; And a horizontal control unit for independently controlling the three lift axes to maintain the horizontal level of the leveling panel.

It is preferable that the horizontal holding device of the present invention further comprises a horizontal detection sensor installed on the leveling panel for detecting whether the leveling panel is horizontal or not.

Preferably, the elevating shaft is provided with a servo motor capable of raising and lowering the elevating shaft to an accurate position.

Further, it is preferable that a work panel on which the workpiece is mounted is further provided on the leveling panel.

According to the present invention, not only the elevation movement of the leveling panel itself but also the leveling of the leveling panel through the adjustment of the fine lift height can be performed by the three elevation shafts independently moving the three points for minimizing the level of the leveling panel There is an effect that control can be performed simultaneously. Particularly, compared to adjusting the horizontal state by moving all the four corners of the conventional art, the process for maintaining the horizontal state is simplified and the processing time is shortened.

&Lt; Example 1 >

The horizontal holding apparatus 100 according to the present embodiment includes a leveling panel 110 installed in parallel in the vertical direction, three elevation shafts 124, 134 and 144, and a horizontal control unit .

First, the leveling panel 110 is installed at the center of the apparatus in a rectangular flat plate shape and is horizontally maintained by control of other components. The leveling panel 110 may serve as a stage for attracting a panel or a substrate, or may serve as a work platform for aligning other panels.

2, the elevation shafts 124, 134, and 144 are installed at three different points on the lower surface of the leveling panel 110, Up and down independently in the vertical direction. At this point, three points of the leveling panel 110 are sufficient at the points where the three elevation shafts 124, 134, and 144 are installed, and they are spaced as far as possible from one another at a wide point of the leveling panel 110 , And the leveling panel 110 can be stably supported.

In this embodiment, it is preferable that the elevating shafts 124, 134, and 144 have a freely rotatable structure, as shown in FIG. 3, that is coupled with the leveling panel 110. This is because the three elevation shafts 124, 134, and 144 can independently move up and down, and the angle of engagement between the elevation shaft and the leveling panel 110 can be variously changed. Therefore, So that the panel can be stably coupled.

Specifically, a spherical insertion groove 112 having a size such that a spherical end 122 of the lifting shaft 124 can be inserted is formed on a lower surface of the leveling panel 110. A lubricant or a bearing is inserted into the space between the spherical insertion slot 112 and the spherical distal end 122. The spherical insertion slot 112 is provided with a spherical end 122 of the lifting shaft inserted in the spherical insertion slot 112 in a non- So that a smooth pivotal motion can be performed.

As shown in FIG. 2, each of the elevation shafts 124, 134 and 144 in the horizontal holding device 100 according to the present embodiment is provided with a servo motor 126 , 136 and 146 are preferably provided. In this embodiment, since the operation of elevating and lowering the elevation shaft at very minute intervals is performed to maintain the level of the leveling panel 110, precise and fine driving control of the elevation shafts 124, 134, and 144 is indispensable . Therefore, the servomotors 126, 136, and 146 are provided below the elevation shaft, respectively, so that accurate driving control of the elevation shaft is possible. Of course, the servo motor may be changed to another driving means for more accurate driving control.

Next, it is preferable that the horizontal holding device 100 according to the present embodiment further includes a horizontal sensing sensor 150. As shown in FIG. 2, the horizontal sensing sensor 150 is installed on the leveling panel 110 and detects whether the leveling panel 110 is horizontal or not. The data sensed by the horizontal sensing sensor 150 is transmitted to a horizontal control unit, which will be described later, and used as data for determining whether the leveling panel is level or not. The mounting position of the horizontal sensing sensor 150 may be variously changed.

Next, the horizontal control unit controls the three elevation shafts 124, 134, and 144 independently to maintain the leveling panel 110 in a horizontal position. For this purpose, the horizontal control unit stores an algorithm for driving the three elevation shafts 124, 134 and 144 to maintain the leveling of the leveling panel 110, And controls the elevation driving and the horizontal holding operation of the leveling panel 110 based on the data.

Further, it is preferable that the horizontal holding apparatus according to the present embodiment further includes displacement monitoring sensors 160a and 160b. As shown in FIG. 2, the displacement sensor is independently provided for each of the elevation axes, and is a sensor installed at a side of the elevation shaft to finely detect the amount of displacement of the leveling panel which is varied by the elevation shaft. The displacement sensor senses a minute displacement amount within a tolerance range of the servomotor when the elevation shaft is provided as a servo motor, and has an advantage of being able to more accurately maintain the leveling level of the leveling panel.

The amount of displacement sensed by the displacement sensor is transmitted to the controller, and the controller is used to maintain the leveling of the leveling panel.
