Description

Technical Field

[0001] The present invention relates to the technical field of OLED laser cutting, and in particular to a high-precision OLED laser cutting device and method. Background Art

[0002] OLED (Organic Light-Emitting Diode) is a current-type organic light-emitting device, which emits light through the injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, which excite the light-emitting molecules and ultimately produce visible light. The OLED screen is a device that displays based on the OLED principle. Its main components include a very thin organic material coating and a glass substrate (or a flexible organic substrate). When current passes through, these organic coatings will emit light. At the same time, compared with traditional display screens, OLED screens can be made lighter and thinner, have a larger viewing angle, and can significantly save power consumption.

[0003] Existing OLED substrates are cut by laser. During the laser cutting operation, workers usually need to rely on manual use of suction cup tools to complete the transfer of the substrate.

[0057] The working principle and working process are as follows: the OLED substrate to be cut is transported by the conveyor 1; according to the size and thickness of the substrate, the corresponding size and number of vacuum suction cups 11 are installed at the bottom of the suction cup installation component 2, and the vacuum suction cup 11 is installed on the air nozzle 24 through a threaded structure.

The height adjustment component 3 is adjusted, and the internal thread ring 32 is manually rotated to drive the threaded rod 31 to lift or lower through the threaded structure. The threaded rod 31 then drives the suction cup installation component 2 fixed at the bottom to work synchronously, thereby changing the lowering position of the vacuum suction cup 11 to match To match the thickness of the substrate and avoid excessive pressure under the vacuum suction cup, which may cause damage to the substrate, the horizontal adjustment component 4 is first manually loosened, so that the end of the positioning bolt 44 is disengaged from the insertion of the positioning hole 42, and then the adjustment rod 41 is extended or retracted from the support rod 43, thereby changing the extension length of the adjustment suction cup mounting component 2 to match the size of the OLED substrate. The reduction motor 10 is powered on to drive the transfer mechanism 9 to work, and the lifting component 91 of the transfer mechanism 9 works. The rotating shaft 911 of the lifting component 91 rotates in a circle, and the rotating shaft 911 drives the active connecting rod 912 to rotate in a circle.

When the toggle rod 953 continues to move, it drives the transmission cylinder 955 to rotate, and the transmission cylinder 955 drives the fixed support tube 956 to rotate. The support tube 956 drives the clamped movable rod 5 to rotate 180 degrees, that is, the OLDE substrate rotates to the top of the workbench 8, and then the lifting assembly 91 drives the OLDE substrate to descend again, so that the substrate falls on the workbench 8, and the vacuum suction cup 11 is released from adsorption.Then, the lifting assembly 91 drives the horizontal adjustment assembly 4, the height adjustment assembly 3, and the suction cup mounting assembly 2 to rise. After reaching the top, the rotating assembly 95 rotates 180 degrees in the opposite direction, so that the vacuum suction cup 11 moves back to the top of the conveyor 1, waiting for the next OLDE substrate to be sucked.
