Based on the embodiments in the present application, all the other embodiments obtained by a person skilled in the art without creative work fall within the protection scope of the present application.

[0045] In order to solve the technical problems of low efficiency and low yield caused by manual attachment of the existing polarizing plate in the prior art, the present application provides an OLED flexible attachment machine and a process method thereof. The following will be described in conjunction with the drawings.

[0046] As shown in Figure 1 The OLED flexible attachment machine of the present application comprises a rack, an optical film module, an attachment module 6 and a polarizing plate module arranged on the rack;

[0047] The optical film module comprises, arranged from one end of the rack along the optical film transmission direction:

[0048] A first feeding unit 1 is used to carry the optical film to be cleaned from one end of the rack to the loading table;

[0049] An OCA cleaning unit 2 receives the optical film to be cleaned and performs surface cleaning; and

[0050] A first film tearing unit 3 is used to suck the cleaned optical film and tear off the protective film on the surface of the optical film;

[0051] The polarizing plate module comprises, arranged in sequence from the other end of the rack along the polarizing plate transmission direction:

[0052] A second feeding unit is used to carry the polarizing plate to be attached from the other end of the rack to the loading table; and

[0053] A second film tearing unit 5 is used to grab the polarizing plate on the loading table and tear off the protective film on the surface;

[0054] The attachment module 6 is located between the first film tearing unit 3 and the second film tearing unit 5, and the attachment module 6 is used to converge the optical film output from the first film tearing unit 3 and the polarizing plate output from the second film tearing unit 5, so that the optical film and the polarizing plate are attached to form a finished product OLED.

[0055] In the automatic attaching process, first, the first feeding unit 1 carries the optical film to be cleaned from one end of the rack to the loading table, at the same time, the second feeding unit is used to carry the polaroid to be attached from the other end of the rack to the loading table, and the OCA cleaning unit 2 receives the optical film to be cleaned and performs surface cleaning; secondly, the first film tearing unit 3 sucks the cleaned optical film and tears off the protective film on the surface of the optical film, and the second film tearing unit 5 grabs the polaroid on the loading table and tears off the protective film on the surface; finally, after the film tearing is completed, the attaching module 6 gathers the optical film output from the first film tearing unit 3 and the polaroid output from the second film tearing unit 5, so that the optical film and the polaroid are attached to form a finished product OLED. The OLED flexible attachment machine of the present application can realize the automatic attachment of the optical film and the polaroid, and can effectively avoid the occurrence of misalignment, bubbles, halos and other phenomena during manual film attachment, greatly improving the production efficiency.

[0056] Optionally, as shown in Figure 2 The first feeding unit 1 includes a first feeding carrying assembly 11, a code scanning assembly 12, a second feeding carrying assembly 13 and a turnover assembly 14. The first feeding carrying assembly 11 includes a first material conveying guide rail and a first carrying arm arranged at one end of the first material conveying guide rail. The code scanning assembly 12 is arranged on one side of the first material conveying guide rail, and the code scanning gun is located above the first material conveying guide rail. When the optical film to be cleaned is placed on the first material conveying guide rail and moves linearly, the code scanning gun of the code scanning assembly 12 can read the code.

[0057] The second feeding carrying assembly 13 is used to carry the scanned optical film to the turnover assembly 14 for turnover, and then transfer the turned-over optical film to the OCA cleaning unit 2 for surface cleaning.

[0058] When the optical film is placed on the loading table of the first feeding carrying assembly 11, the carrying arm moves to drive the optical film to pass through the code scanning gun of the code scanning assembly 12 to read the code, and then the second feeding carrying assembly 13 carries the optical film to the loading table of the turnover assembly 14, and then performs a turnover action. Then the second feeding carrying assembly 13 carries the optical film to the OCA cleaning unit 2. If the optical film does not need to perform a turnover action, the second feeding carrying assembly 13 directly transfers the material from the first feeding carrying assembly 11 to the OCA cleaning unit 2.

[0059] As shown in Figure 3As shown, the OCA cleaning unit 2 comprises a first cleaning carrying assembly 21, a primary cleaning mechanism, a second cleaning carrying assembly 25 and a secondary cleaning mechanism 26; wherein the first cleaning carrying assembly 21 is used to receive the optical film to be cleaned transferred from the first feeding unit 1, and drive the optical film to move through the primary cleaning mechanism; the primary cleaning mechanism is used to respectively perform ultrasonic primary cleaning on the upper surface and the lower surface of the optical film; the second cleaning carrying assembly 25 drives the optical film cleaned by ultrasonic cleaning to move through the secondary cleaning mechanism 26, and the secondary cleaning mechanism 26 is used to perform alcohol secondary cleaning on the optical film.

[0060] Optionally, the primary cleaning mechanism comprises a first ultrasonic cleaning assembly 22, a third cleaning carrying assembly 23 and a second ultrasonic cleaning assembly 24; wherein the first ultrasonic cleaning assembly 22 is used to perform ultrasonic cleaning on the upper surface of the optical film to be cleaned; the second cleaning carrying assembly 25 is used to pick up the optical film with the cleaned upper surface to pass through the second ultrasonic cleaning assembly 24 to clean the lower surface, and transfer the optical film with both sides cleaned to the second cleaning carrying assembly 25 to wait for secondary cleaning.

[0061] Specifically, when the optical film is transferred from the first feeding unit 1 to the stage of the first cleaning carrying assembly 21, the carrying arm moves to drive the optical film to pass through the first ultrasonic cleaning assembly 22, and the first ultrasonic cleaning assembly 22 cleans the upper surface of the optical film by the high-frequency plasma air knife emitted by the USC ultrasonic cleaning machine. After cleaning the upper surface, the third cleaning carrying assembly 23 picks up the optical film to pass through the second ultrasonic cleaning assembly 24, and the lower surface of the optical film is cleaned by the high-frequency plasma air knife, and then transferred to the stage of the second cleaning carrying assembly 25. The second cleaning carrying assembly 25 drives the optical film to pass through the secondary cleaning mechanism 26, and the alcohol is sprayed on the dust-free cloth in the secondary cleaning mechanism 26, and the cleaning effect is achieved by the contact wiping of the optical film by the wetted dust-free cloth. The whole process of alcohol wiping of the dust-free cloth is divided into two times to achieve the purpose of cleaning qualification. In order to ensure the efficiency, two stages are arranged in the second cleaning carrying assembly 25, which is matched with the OCA transfer table in the secondary cleaning mechanism 26 to realize the simultaneous cleaning of two optical films. When the optical film is cleaned, it enters the film tearing process.

[0064] As shown in Figure 5 The core carrying arm assembly 4 includes a first attaching carrying arm 41 and a second attaching carrying arm 42 arranged in parallel, and when one of the first attaching carrying arm 41 or the second attaching carrying arm 42 is full, the third film tearing and carrying assembly 34 transfers the polaroid to the other one of the first attaching carrying arm 41 or the second attaching carrying arm 42.

[0065] Specifically, the first film tearing and carrying assembly 31 in the first film tearing unit 3 sucks the optical film from the stage of the second cleaning and carrying assembly 25 and transfers to the second film tearing and carrying assembly 32; the fine-tuning stage carries out fine-tuning alignment action after the current position is calculated through the detection of the first visual positioning assembly 33 and the photographing of the CCD camera; the optical film is transferred to the stage of the attaching carrying arm in the core carrying arm assembly 4 and moves in front of the robot film tearing assembly; in order to improve work efficiency, the first film tearing unit 3 is in double-line double-station form; when the material on the second attaching carrying arm 42 assembly in the core carrying arm assembly 4 is full, the third film tearing and carrying assembly 34 can transfer the optical film to the OCA alignment stage of the first attaching carrying arm 41 in the core carrying arm assembly 4. The first attaching carrying arm 41 sends the material in front of the first robot film tearing assembly 36, and the robot in the assembly carries the film tearing tool to tear off the protective film on the optical film; in order to prevent the film tearing action from affecting the position of the optical film, the first attaching carrying arm 41 carries the material to the lower side of the second visual positioning assembly 37, and the current product position is calculated through the detection of the higher-precision visual system. When the material on the first attaching carrying arm 41 is full, the third film tearing and carrying assembly 34 will transfer the material to the OCA alignment stage of the second attaching carrying arm 42, and the film tearing action is performed through the first robot film tearing assembly 36; the current state of the product is calculated through the detection and positioning of the second visual positioning assembly 37, and then the alignment stage is aligned.

[0066] As shown in Figure 6As shown, the second film tearing unit 5 includes a polaroid loading arm assembly 51, a fourth film tearing and carrying assembly 52, a fifth film tearing and carrying assembly 54, and a second mechanical arm film tearing assembly 55; wherein the polaroid loading arm assembly 51 is used to grab the polaroid from the stock bin and then transfer it to the fourth film tearing and carrying assembly 52; the fourth film tearing and carrying assembly 52 drives the polaroid to fine-tune the alignment; the fifth film tearing and carrying assembly 54 is used to grab the polaroid after the alignment is completed and then transfer it to the core arm assembly 4; the core arm assembly 4 carries the polaroid and moves to the second mechanical arm film tearing assembly 55 for film tearing treatment.

[0067] When the optical film starts to move from the first loading unit 1, the attached polaroid also starts to move from the other end of the device at the same time. The second film tearing unit 5 mainly includes a polaroid loading arm assembly 51, a fourth film tearing and carrying assembly 52, a third visual positioning assembly 53, a fifth film tearing and carrying assembly 54, and a second mechanical arm film tearing assembly 55. The polaroid loading arm assembly 51 grabs the polaroid from the stock bin and then transfers it to the fourth film tearing and carrying assembly 52. The polaroid is driven by the arm to pass under the third visual positioning assembly 53 for photographing detection. After the initial photographing detection, the polaroid will also be subjected to initial alignment action. After the alignment is completed, the polaroid will be transferred by the gripper of the fifth film tearing and carrying assembly 54 to the attached arm in the core arm assembly 4. The attached arm is in double-line double-station form and mainly uses two long-stroke four-motor linear motors as the core. Two action-carrying OCA alignment load tables and two action-carrying POL alignment load tables are provided. When the material on one line is fully loaded, it will be transferred to the other line. The polaroid will be sent to the working area of the second mechanical arm film tearing assembly 55 by the POL alignment load table of the attached arm. The second mechanical arm film tearing assembly 55 is divided into four stations and arranged on both sides of the core arm assembly 4. Two stations on one side can work at the same time. After the polaroid is torn in the station of the second mechanical arm film tearing assembly 55, the POL alignment load table will transport the polaroid to the working area of the secondary visual positioning assembly. The position of the polaroid will be detected again by the visual system. After the detection is completed, the POL alignment load table in the attached arm assembly will perform alignment action.

[0068] As shown in Figure 7 The attached module 6 includes four attached stations 61, which are arranged side by side in pairs and located above the core arm assembly 4.

[0070] When the alignment action is completed, it will move to the lower side of the lamination module 6, the lamination module 6 is mainly composed of four lamination stations 61, which are respectively located above the two lamination arms. When the POL alignment load table reaches the position, the four lamination head stations of the lamination module 6 will descend to adhere the polarizing sheet to the adhesive plate on the lamination head. At this time, the OCA alignment load table of the lamination arm will also move to the lower side of the lamination module 6 after completing the alignment action, and the lamination head will descend to coincide the OCA material with the polarizing sheet, and the lamination roller above the adhesive plate will roll and press tightly, and finally complete the lamination action. When the lamination roller works, the lamination head will rise as a whole and return to the original position. After completing the lamination action, the OCA alignment load table on the lamination arm will move to the working area of the discharging unit 7, and the discharging carrying arm 71 will transfer the finished OLEDs after lamination to the lower side of the finished product detection assembly 72, and the vision system will take pictures to detect the state of the finished OLEDs after lamination, mainly to detect whether the lamination position is correct, whether there are bubbles and halos. After detection, the product carrying arm assembly 73 will carry the product to the discharging table 75 or the NG material placing table 74.
