Mask transmission method

Abstract

The embodiment of the invention discloses a mask plate transmission method, which comprises the following steps of: according to the size of a mask plate along a second direction and the initial position of the mask plate, firstly controlling a manipulator to adsorb the mask plate in a tray by adopting a first group to an nth group of suction cups which point to the direction of a rotating table along the tray, the adsorbed mask plate is conveyed to the front end of the rotating table from the tray in the direction that the tray points to the rotating table; then controlling the manipulator to move for a first distance along the direction that the rotating table points to the tray, adsorbing the mask at the front end of the rotating table by adopting the first group to the nth group of suction cups along the direction that the rotating table points to the tray, and conveying the adsorbed mask from the front end to the rear end of the rotating table along the direction that the tray points to the rotating table; the length of the forks is fully utilized, so that the clamping jaws can convey the mask to the workpiece table at the rear end of the rotating table only through one step, the time for conveying the mask from a tray to the workpiece table is shortened, and the mask conveying efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of stretching equipment control, and in particular, to a mask transmission method. Background technique [0002] The net welding process is the key process of OLED small molecule organic material evaporation production line. In the process of stretching and welding, the high-precision evaporation screen (metal film) will be fixed on the screen frame. substrate surface. [0003] In the existing process of fixing the screen on the screen frame, the manipulator takes out the screen from the designated position on the tray and transfers it to the front end of the rotary table, and the gripper grips the screen from the front end of the rotary table to the rear of the rotary table end, and finally the grippers transport the screen from the rear end of the rotary table to the workpiece table for the second time. During this process, the manipulator cannot directly transfer the screen from t...

Problems solved by technology

During this process, the manipulator cannot directly transfer the screen from the pallet to the rear end of the rotary table due to the travel limit, and the grippers can transport it to the workpiece table at one time, and the gripper itself is also limited by the stroke, and the grippers are moving the screen from the rotary table. The process of clamping the front end to the workpiece table requires secondary handling, which takes a long time, greatly prolongs the time for transferring the screen to the screen frame, and reduces the transportation efficiency of the screen
