As shown in fig. 5 and 10, the alignment stage 190 may adjust the position of the adsorption stage 110 and may be coupled to the underside of the adsorption stage 110.
The adsorption stage 110 and the alignment stage 190 may be connected by a separate frame, and the rack unit 150 and the alignment assembly 160 may be interposed between the adsorption stage 110 and the alignment stage 190.
The adsorption stage 110, the rack unit 150, the alignment assembly 160, and the alignment stage 190 may form a single structure, and are preferably configured to reduce the weight of the structure since the entire structure including the adsorption stage 110 must be inverted.
The alignment platform 190 may be configured as a UVW platform in order to reduce the weight of the structure. In the UVW platform, a U cylinder (U) is provided at one side of the platform, and a V cylinder (V) and a W cylinder (W) are provided at both sides of the platform in the same direction.
For example, when only the U cylinder (U) is operated, the adsorption stage 110 may move in the X direction, and when the V cylinder (V) and the W cylinder (W) are operated in the same straight direction, the adsorption stage 110 may move in the Y direction. Further, when the U cylinder (U), the V cylinder (V), and the W cylinder (W) are operated clockwise or counterclockwise, the adsorption platform 110 may be tilted clockwise or counterclockwise on the XY plane.
A process of attaching a film to a display panel by the film attaching apparatus of the display panel configured as described above will be described as follows.
When the films accommodated in the cassette are supplied onto the film supply unit 10 one by the upper conveyor, the films are aligned in position by the operation of the film supply unit 10, and when the film transfer unit 20 transfers the films mounted on the film supply unit 10 to the film adsorption stage 40, a vacuum suction pressure is applied to the film adsorption stage 40, and then the films may be fixed to the film adsorption stage 40.
The adhesive surface of the film is provided with release paper adhered thereto, and when the release paper of the film is fixed to the film adsorption stage 40 such that the release paper of the film faces upward, the release paper can be separated from the film while passing through the film adsorption stage 40 by the release paper peeling unit 30.
When the release paper is separated, the film adsorption stage 40 on which the film is disposed may move to the lower side of the reverse adsorption unit 100, and may wait so that the adhesive surface of the film faces upward.
Meanwhile, the display panel is supplied above the adsorption platform 110 in a state of being seated on the fork, when the stand pin 151 is raised above the adsorption surface of the adsorption platform 110, the stand pin 151 supports the rear surface of the display panel, and the fork may be conveyed away from the adsorption platform 110. In addition, when the holder pins 151 are lowered again from the adsorption surface of the adsorption platform 110, the display panel may be seated on the adsorption platform 110.
When the display panel is placed on the adsorption platform 110, the camera assembly 180 photographs the display panel with respect to the adsorption platform 110, and the control device compares the photographed image with a reference position, so that the operation of the alignment assembly 160 can be adjusted.
The conveying rollers 161 are driven to contact all four side surfaces of the display panel and push the display panel in a horizontal direction so that the display panel can be aligned in position with respect to the adsorption platform 110.
When the position of the display panel is aligned, the reverse motor 141 is operated, and the rotation torque converted by the decelerator 141 rotates the rotation shafts 121 and 122 so that the adsorption platform 110 around the rotation shafts 121 and 122 may be rotated by 180 °.
When the upper and lower sides of the adsorption platform 110 are reversed, the driving cylinder 172 is operated, and the positioning pin 171 is moved in the horizontal direction to engage the groove or hole at one side of the adsorption platform 110, so that the reversed position of the adsorption platform 110 can be stably fixed.
When the reverse position of the adsorption stage 110 is fixed, the camera assembly 180 photographs the display panel with respect to the adsorption stage 110, and the control device compares the photographed image with a reference position, so that the operation of the alignment stage 190 can be adjusted.
By horizontally moving or tilting the adsorption platform 110 according to the operation of the U cylinder (U), the V cylinder (V), and the W cylinder (W), the adsorption platform 110 may be aligned in position with respect to the film adhesion position, and may wait to make the display panel face down.
As described above, when the display panel on the side of the reverse adsorption unit 100 and the film on the side of the film adsorption stage 40 face in place in the vertical direction, the film may be attached over the entire surface of the display panel by controlling the film adsorption stage 40.
The above description is merely illustrative of the technical spirit of the present disclosure, and various modifications and changes will be possible to those skilled in the art to which the present disclosure pertains without departing from the essential features of the present disclosure.
