[0003] A Chinese patent discloses an OCA optical adhesive attaching device (authorization announcement number CN 219950027 U). The patented technology can make the optical adhesive contact with the parts through a pressing component and complete the attaching process; by setting two positioning tables, the loading and attaching of the parts can be carried out simultaneously, thereby improving the processing efficiency, and there is no need to manually load the parts one by one. However, when the OCA device needs to be transferred to a place of use, it is inconvenient for users to move, and it consumes a lot of manual labor.
