At present, in multiple process stages of the production process of flexible display devices, mechanical alignment methods are used to align functional film materials. However, since the functional film materials have a small Young's modulus, they will deform under a relatively small load, so they are easily damaged during mechanical alignment. In addition, the alignment accuracy of mechanical alignment is poor, which makes it impossible to meet the high-precision alignment requirements of the subsequent film lamination process.

[0047] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0050] like Figure 1 As shown, the processor 1001 calls the film alignment program stored in the memory 1005 and executes the operations in each embodiment of the following film alignment method.

[0051] Based on the above hardware structure, an embodiment of the film material alignment method of the present invention is proposed.

[0052] Reference Figure 2 , Figure 2 This is a schematic flow chart of a first embodiment of a film alignment method of the present invention, the method comprising:

[0053] Step S10, blowing air to the target film material through the air flotation module in the film material displacement stage, so that the target film material is separated from the alignment platform in the film material displacement stage;

[0054] Step S20, moving the calibration block in the displacement stage of the film material to push the target film material to perform an alignment operation.

[0055] The film alignment method of the present embodiment is applied to the film alignment equipment of the optoelectronic display device production mechanism. The film alignment equipment can be a terminal or a PC device. For the convenience of description, the film alignment equipment is described as an example; the film alignment equipment includes: a film alignment displacement stage and a film lifting arm suction cup mechanism; the film alignment equipment sucks the target film material through the material taking suction cup in the slice mechanism, and blows ion wind to the target film material sucked by the first suction cup module through the ion rod in the slice mechanism, shakes the target film material through the shaking motor in the slice mechanism, and measures the thickness of the film material after the shaking operation through the thickness sensor in the slice mechanism. The target film material is tested for thickness to determine whether the target film material is a single piece. When it is determined that the target film material is a single piece, the target film material is moved to the alignment platform in the film material displacement platform, and the film material moving arm suction cup mechanism is moved above the target film material, and the film material correction plate in the film material moving arm suction cup mechanism is lowered to form a gap of a preset height between the film material correction plate and the alignment platform; the film material alignment device blows air to the target film material through the air flotation module in the film material displacement platform to separate the target film material from the alignment platform surface, and moves the correction block in the film material displacement platform to push the target film material to perform alignment operations. It should be noted that the film material alignment device can perform alignment operations on a variety of target film materials, not limited to the type and size of the film materials, nor to the type of flexible device carriers, and can be compatible with flexible devices and film materials of different sizes.

[0056] The film alignment method of this embodiment uses the air flotation module in the film material displacement stage to blow air to the target film material so that the target film material is separated from the alignment platform; and the correction block in the film material displacement stage is moved to push the target film material to perform an alignment operation. The present invention uses the air flotation module and the correction block in the film material displacement stage to perform an alignment operation on the target film material, thereby improving the accuracy of the film material alignment and reducing the damage rate of the film material.

[0057] The following is a detailed description of each step:

[0058] Step S10, blowing air to the target film material through the air flotation module in the film material displacement stage, so that the target film material is separated from the alignment platform in the film material displacement stage;

[0059] In this embodiment, the film material alignment device starts the cylinder in the air flotation module in the film material alignment displacement platform, so that the cylinder blows out clean and dry air, and the clean and dry air blown out by the cylinder is blown toward the target film material through the air flotation micropores on the air flotation table in the air flotation module, thereby making the target film material separate from the surface of the alignment platform; it should be noted that the air flotation module in the film material alignment displacement platform includes: a cylinder, an air flotation table and air flotation micropores; when the clean and dry air is blown toward the target film material through the air flotation micropores, the direction of the airflow is perpendicular to the surface of the alignment platform.

[0060] Specifically, before step S10, the following steps are included:

[0061] Step a, moving the target film material onto the alignment platform;

[0062] In this step, the film material alignment device moves the target film material to the alignment platform in the film material alignment displacement carrier through the material picking suction cup in the slicing mechanism according to the detection result obtained by the thickness sensor in the slicing mechanism. It should be noted that the material picking suction cup in the slicing mechanism adopts a special suction nozzle for thin film products, which will not cause film wrinkles when sucking the film; the film material alignment device can align film materials of various sizes. Optionally, before the step of sucking the target film material through the material picking suction cup, the film material alignment device obtains the size of the target film material in the alignment instruction when detecting the alignment instruction input by the relevant operator, and determines the target film material that needs to be aligned this time according to the size;

[0063] Step b, moving the film material moving arm suction cup mechanism in the film material alignment device to above the target film material, and lowering the film material correction plate in the film material moving arm suction cup mechanism to form a gap of a preset height between the film material correction plate and the alignment platform.

[0064] In this step, the membrane material alignment equipment moves the membrane material moving arm suction cup mechanism to above the target membrane material, and drives the membrane material correction platen in the membrane material moving arm suction cup mechanism to be lowered, so that a gap of a preset height is formed between the membrane material correction platen and the alignment platform; it should be noted that a gap of a preset height is formed between the membrane material correction platen and the alignment platform, and the height of the gap can be optionally 3-5mm, so that the correction block on the alignment platform can be embedded in the correction block avoidance groove in the template correction platen, so as to prevent the target membrane material from leaving the gap between the membrane material correction platen and the alignment platform when the air flotation module is blown.

[0065] Furthermore, before step a, the method includes:

[0066] Step c, blowing ion wind to the target film material through the ion rod in the slicing mechanism, and shaking the target film material through the shaking motor in the slicing mechanism, and moving the target film material after the shaking operation to a preset detection position, and detecting the thickness of the target film material through the thickness sensor in the slicing mechanism to obtain a detection result;

[0067] In this step, after the film material alignment device sucks up the target film material through the material picking suction cup in the sheeting mechanism, it blows ion wind to the target film material through the ion rod in the sheeting mechanism, and shakes the target film material through the shaking motor in the sheeting mechanism. Through the ion wind blowing operation and the shaking operation, other film materials that are adhered to the target film material sucked up by the material picking suction cup fall off, ensuring that the number of target film materials sucked up is a single piece; after the film material alignment device blows ion wind and shakes the target film material, the thickness of the target film material is detected by the thickness sensor in the sheeting mechanism , and obtain the test results; it should be noted that when the material-picking suction cup in the sheeting mechanism absorbs the target film material, since the target film materials are stacked together in the loading film box, there may be static electricity and other conditions, causing the material-picking suction cup to absorb multiple pieces of target film materials; the shaking motor in the sheeting mechanism is installed above the material-picking suction cup. When the target film material is shaken, the shaking motor is started, causing the material-picking suction cup to shake up and down, thereby driving the target film material sucked by the material-picking suction cup to shake up and down; the thickness sensor in the sheeting mechanism can optionally be a clamping thickness sensor and an infrared thickness sensor.

[0068] Step d, if the detection result is that the thickness of the target film material is equal to the preset thickness value, it is determined that the number of the target film material is a single piece, and the steps are performed: the target film material is moved to the alignment platform in the film material alignment displacement stage by the material taking suction cup in the sheet separation mechanism;

[0069] In this step, when the film alignment device obtains the detection result that the thickness of the target film material is equal to the preset thickness value, it is determined that the number of target film materials sucked by the material suction cup in the slicing mechanism is a single piece, and the step is executed: the target film material is moved to the alignment platform in the film material alignment displacement carrier by the material suction cup in the slicing mechanism. It should be noted that the preset thickness value is determined according to the production standard of the functional film material. Different functional film materials have different preset thickness values. The relevant R&D personnel set the preset thickness value in the film alignment device in advance.

[0070] Step e. If the detection result shows that the thickness of the target film material is greater than the preset thickness value, the target film material is shaken and the thickness is detected until it is determined that the number of target film materials is a single piece. Then, the following steps are executed: the target film material is moved to the alignment platform in the film material alignment displacement carrier by the material picking suction cup in the sheet separation mechanism.

[0071] In this step, when the film material alignment device obtains the detection result that the thickness of the target film material is greater than the preset thickness value, it is determined that the number of target film materials sucked by the material picking suction cup in the sheeting mechanism is not a single piece, and the target film material sucked by the material picking suction cup is shaken to make other target film materials fall off, and then the material picking suction cup is moved to the preset detection position, and the thickness of the target film material is detected. The above steps are repeated until it is detected that the number of target film materials is a single piece, and the execution step is: the target film material is moved to the alignment platform in the film material alignment displacement carrier by the material picking suction cup in the sheeting mechanism.

[0072] Step S20, moving the calibration block in the displacement stage of the film material to push the target film material to perform an alignment operation.

[0073] In this embodiment, the film alignment device moves the calibration block in the film alignment displacement stage to push the target film material blown by the clean and dry air to reach a preset alignment position to complete the alignment operation.

[0074] Specifically, step S20 includes:

[0075] Step f, obtaining the size of the target film material to determine a preset alignment position of the target film material, and determining a stop position of the film material relative to the calibration block in the displacement stage according to the preset alignment position;

[0076] In this step, the film material alignment equipment obtains the size of the target film material, determines the preset alignment position of the target film material, and determines the stop position of the correction block in the film material displacement carrier according to the preset alignment position; it should be noted that target film materials of different sizes have different preset alignment positions on the alignment platform, and the target film material needs to be pushed to the preset alignment position by the correction block on the alignment platform to complete the alignment operation; the fixed limit block is installed on one side of the upper surface of the alignment platform, and the correction block is installed on the other three sides, and the ends of the correction blocks away from the alignment platform are made of Teflon material that causes less mechanical contact damage to the target film material, and the correction blocks can be moved, and the final stop position of each correction block is determined according to the preset alignment position of the target film material, and the target film material can be pushed to the preset alignment position by moving each correction block to the corresponding stop position.

[0077] Step g: moving the calibration block along the guide groove in the film material alignment displacement stage to the stop position to push the target film material to the preset alignment position to complete the alignment operation.

[0078] In this step, the film material alignment equipment moves each correction block to the corresponding stop position along the guide groove in the film material alignment displacement carrier according to the stop position, and pushes the target film material to the preset alignment position to complete the alignment operation; it should be noted that the guide groove is located on the alignment platform in the film material alignment displacement carrier, and the correction block on the alignment platform is installed in the guide groove, each correction block has a corresponding guide groove, and the correction blocks move along the guide groove; the correction block avoidance groove on the film material correction plate in the film material lifting arm suction cup mechanism corresponds one by one to the guide groove on the alignment platform, and when the correction block moves, the correction block avoidance groove can prevent the film material correction plate from hindering the movement of the correction block.

[0079] The film alignment method of this embodiment sucks the target film material out of the loading film box through the material taking suction cup in the slicer mechanism, and blows ion wind to the target film material sucked by the first suction cup module through the ion rod in the slicer mechanism, shakes the target film material through the shaking motor in the slicer mechanism, and detects the thickness of the target film material after the shaking operation through the thickness sensor in the slicer mechanism to determine whether the number of target film materials is a single piece. When it is determined that the number of target film materials is a single piece, the target film material is moved to the alignment platform in the film material alignment displacement carrier, and the film material moving arm suction cup mechanism is moved above the target film material, and the film material alignment in the film material moving arm suction cup mechanism is The positive pressure plate is lowered to form a gap of preset height between the film correction plate and the alignment platform; the film alignment device blows air to the target film material through the air flotation module in the film alignment displacement platform to make the target film material leave the surface of the alignment platform, and moves the correction block in the film alignment displacement platform to push the target film material to perform alignment operation; the present invention moves the target film material to the alignment platform in the film alignment displacement platform through the material picking suction cup in the slicer mechanism, and lowers the film correction plate in the film lifting arm suction cup mechanism, and then performs alignment operation on the target film material through the air flotation module and the correction block in the film alignment displacement platform, thereby improving the accuracy of film alignment and reducing the damage rate of the film material.

[0080] Furthermore, based on the first embodiment of the film material alignment method of the present invention, a second embodiment of the film material alignment method of the present invention is proposed.

[0081] The second embodiment of the film material alignment method is different from the first embodiment of the film material alignment method in that, after step S20, the method further includes:

[0082] Step h, stopping blowing air toward the target film material, so that the target film material descends to the alignment platform, and the target film material is sucked by the film material loading suction cup in the film material lifting arm suction cup mechanism;

[0083] In this step, after the film alignment device completes the alignment operation of the target film, it closes the cylinder in the air flotation module and stops blowing air to the target film, so that the single target film falls onto the alignment platform and is sucked up by the film loading suction cup in the film lifting arm suction cup mechanism. It should be noted that the film loading suction cup in the film lifting arm suction cup mechanism uses a special suction nozzle for thin film products, which will not cause film wrinkles when sucking the film.

[0084] Step i: Move the target film material to the film material bonding platform through the film material loading suction cup.

[0085] In this step, the film material alignment equipment absorbs the target module through the film material loading suction cup in the film material moving arm suction cup mechanism, and then moves the target module to the film material bonding platform by moving the film material moving arm suction cup mechanism. It should be noted that after the alignment is completed, the single-piece target module is moved to the film material bonding platform and can be optionally directly bonded with the corresponding optoelectronic display device, or fine-tuned and aligned through the film material bonding platform and then bonded with the corresponding optoelectronic display device.

[0086] After completing the alignment operation of the target film material, the film alignment equipment of this embodiment closes the air flotation module, so that the target film material drops onto the alignment platform, and absorbs the single piece of target film material through the film loading suction cup, and then moves the target film material to the film bonding platform to ensure the connection with the subsequent film bonding steps, thereby improving the accuracy of the film bonding operation.
