[0052] Embodiment 2

[0053] In this embodiment, a method for adsorbing an adsorption stage for liquid crystal panel detection is proposed. Based on the adsorption stage for liquid crystal panel detection in the first embodiment, the method includes the following steps:

[0054] S1: Detecting the flatness of the first plate 21. If the measured flatness does not reach a preset value, the flatness of the first plate 21 can be adjusted by an adjustment component until the detected flatness of the first plate 21 reaches a preset value;

[0055] S2: according to the shape and size of the panel body, the plurality of air holes on the first plate 21 are formed into an adsorption area matching the shape and size of the panel body, and the panel body is vacuum adsorbed through the formed adsorption area;

[0056] S3: According to the shape and size of the PCB board, the position of the adjusting member 3 in the supporting assembly relative to the second flat plate 22 in the first direction is adjusted, and the position of the adsorption assembly relative to the adjusting member 3 in the second direction is adjusted, so that the shape and size of the whole formed by the suction cup assemblies in the adsorption assembly match the PCB board;

[0057] S4: Adjust the position of the suction cup assembly in the vertical direction so that each suction cup assembly can be located on the same plane, so as to support and adsorb the PCB board.

[0058] The specific adsorption process of the adsorption method of the adsorption stage for liquid crystal panel detection in this embodiment is as follows: first, the flatness of the first flat plate 21 is detected by the detection component. If the measured flatness does not reach the preset value, the flatness of the first flat plate 21 can be adjusted by fine-tuning the adjustment component until the flatness of the first flat plate 21 detected by the detection component reaches the preset value, that is, the flatness of the first flat plate 21 at this time can meet the flatness of the panel body required for camera detection; then, according to the specific shape and size of the panel body, the opening and closing states of each second vacuum tube are controlled so that the pores on the first flat plate 21 can form an adsorption area that matches the shape and size of the panel body, and the panel body is vacuum adsorbed through the formed adsorption area.

[0059] Since the PCB board and the panel body are integrally formed: then, according to the shape and size of the specific PCB board, the adjusting member 3 is slid on the linear rail 4 to a suitable position, and at the same time, the connecting member and the second bolt are driven to move, so that the second bolt is moved to the corresponding position on the slide rail, and the second bolt is tightened to tighten the connecting member to the surface of the slide rail, so that the connecting member and the adjusting member 3 are stopped at a suitable position on the linear rail 4, so as to drive the suction cup body 9 on the adjusting member 3 to move to a suitable position relative to the second flat plate 22 along the first direction; then the support frame 8 is slid relative to the adjusting member 3 along the second direction, and the first bolt 7 is moved relative to the mounting through hole 31 on the adjusting member 3, and the first bolt 7 is tightened to the second panel 82 on the support frame 8, so as to tighten the support frame 8 to the adjusting member 3, so as to stop the support frame 8 and the suction cup body 9 on the support frame 8 at a suitable position on the mounting through hole 31, so as to drive the suction cup body 9 on the support frame 8 to move to a suitable position relative to the adjusting member 3 along the second direction; thereby, the shape and size of the whole formed by each suction cup body 9 arranged on the support frame 8 can match the PCB board.

[0060] Finally, the first vacuum tube 6 is adjusted by threading to adjust the position of the suction cup body 9 relative to the adjusting member 3 in the vertical direction, so that each suction cup body 9 can be located on the same plane, and the flatness of each suction cup body 9 is measured by the detection component; if the measured flatness does not reach the preset value, the first vacuum tube 6 is adjusted by threading to adjust the position of the suction cup body 9 in the vertical direction until the flatness of each suction cup body 9 detected by the detection component reaches the preset value, so as to ensure that each suction cup body 9 is located on the same plane, so that the flatness of the PCB board adsorbed on each suction cup body 9 is better; on the one hand, it can avoid the concave and convex suction cup body 9 from damaging the PCB board, and on the other hand, it can avoid interference between the PCB board and the panel body during the adsorption process, so as to further ensure the flatness of the panel body; then the panel body is photographed and detected by the camera to complete the adsorption and detection process of the entire liquid crystal panel. Among them, since the panel body and the PCB board are flexibly connected, the panel body is adsorbed into the adsorption area on the first flat plate 21, and the PCB board is adsorbed onto the suction cup body 9 at the same time, which will not affect the connection between the panel body and the PCB board.

[0061] The adsorption platform used for liquid crystal panel detection in this embodiment can, on the one hand, provide effective adsorption for the panel bodies of various types of liquid crystal panels and make them have a higher flatness, so as to meet the high flatness requirements of the liquid crystal panels required for camera detection; on the other hand, it can provide effective support and adsorption for various types of PCB boards in the liquid crystal panels and make them have a higher flatness, so as to further meet the high flatness requirements of the liquid crystal panels required for camera detection.
