Description

[0002] OLED, also known as organic electro-laser display or organic light-emitting semiconductor, is a current-type organic light-emitting device that emits light through the injection and recombination of carriers. 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 be injected into the hole transport layer and the electron transport layer respectively, and then migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules and ultimately producing visible light. When producing OLED, the BP film and the COP film need to be spliced ​​to form a BP+COP product.

[0003] The current production process for splicing BP membranes and COP membranes is to cut a single layer of film, attach an upper layer of film, and cut it again. At least four die-cutting devices and multiple sets of compounding machines are required to produce the spliced ​​film.

[0032] Example 2

[0033] according to Figure 4 and Figure 5 As shown, this embodiment provides a process for splicing a BP membrane and a COP membrane using a BP membrane and a COP membrane splicing device in Example 1, characterized in that it includes the following steps:

[0034] Step 1: First, the BP film and COP film are cut synchronously using the PF carrier film and the cutting mechanism, and the cut waste films are rolled up;

[0035] Since the BP film used for splicing is much smaller than the COP film, the waste material rolled up after cutting the BP film can be reused. When it is reused and put into production again, the previously cut parts will be staggered and fed according to the cutting requirements.

[0036] Step 2: Laminating and splicing the BP film and the COP film on the cut PF carrier film, and then rolling up the PF carrier film with the BP film on the upper layer for recycling;

[0037] The upper PF carrier film is not cut synchronously with the BP film during cutting, so the upper PF carrier film that is rolled up after the BP film is cut and peeled can be reused many times.

[0038] Step 3: Laminate another layer of RF film on the spliced ​​and laminated BP film and COP film and cut it again. After cutting, roll up the RF film waste;

[0039] During cutting, the cutting knife simultaneously cuts the lower PF carrier film below the COP according to the size of the BP film and the COP film after splicing.

[0040] Step 4: Finally, the cut PF carrier film and the BP film, COP film and RF film spliced ​​above are peeled off from the lower PF carrier film, and the waste material of the cut lower PF carrier film is rolled up, and the peeled material falls into the collection box.

[0041] When the equipment is moved into the factory for layout, the universal wheels are pushed out of the shrinkage grooves using the lifting cylinders to lift the support feet off the ground. Then the entire equipment can be easily moved for position adjustment.
