Abstract
The present invention relates to a horizontal holding device capable of vertically adjusting the height of three points while vertically driving the leveling panel by means of three elevating shafts for vertically driving three different points of the leveling panel The horizontal holding device according to the present invention includes: a leveling panel having a plate material 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.
Description
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
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.
