  • Patent number: 9778497
    Abstract: A bearing platform and a COF repair bonder are disclosed. The bearing platform has adjustable size and good practicability. Therefore, the designed volume of the COF repair bonder and its weight can be reduced, thereby saving space and being easier to move. The bearing platform includes a fixed part and at least one extension which is connected to the fixed part and can move back and forth in a first direction relative to the fixed part. Upper surfaces of the extension and the fixed part can be provided with at least one extension arm support for carrying a display panel respectively. Each extension arm support can move back and forth in a second direction relative to the fixed part, with the first direction and the second direction intersecting one another.
