[0027] Reference Figures 1 to 7 The present invention provides a further description of an embodiment of an OLED screen adhesive coating device.

[0028] An OLED screen adhesive coating device includes a coating machine 1 and an adhesive coating component 2, the adhesive coating component 2 being disposed within the coating machine 1; it also includes: a hollow fixing frame 3, disposed within the coating machine 1 and fixedly connected to the coating machine 1; a fixing groove 4, formed within the fixing frame 3; two fixing blocks 5, symmetrically arranged within the fixing groove 4 and slidably connected to the fixing groove 4; a fixing mechanism, disposed within the coating machine 1, used to clamp and fix the OLED screen to prevent the OLED screen from moving or shifting during adhesive coating, thus affecting the accuracy of adhesive coating; a cleaning mechanism, disposed within the coating machine 1, used to clean the surface of the OLED screen to prevent dust from adhering and affecting the adhesion effect of the adhesive; and a lifting component, disposed on the coating machine 1, used to lift the cleaning mechanism to clean OLED screens of different thicknesses.

[0029] Reference Figure 3 In a preferred embodiment, the fixing mechanism includes: a motor frame 6, which is disposed on the fixing frame 3 and fixedly connected to the fixing frame 3; a fixed motor 7, which is fixedly connected to the motor frame 6; a bidirectional lead screw 8, which is fixedly connected to the output end of the fixed motor 7 and rotatably connected to the fixing frame 3; and two rotating components, which are symmetrically arranged on the bidirectional lead screw 8.

[0030] During operation, the fixed motor 7 is started, which drives the bidirectional lead screw 8, which is fixedly connected to the output end of the fixed motor 7, to rotate on the fixed frame 3.

[0031] Reference Figure 3 In a preferred embodiment, the rotating component includes: a first slider 9, which is disposed on a bidirectional lead screw 8, helically connected to the bidirectional lead screw 8, and slidably connected to the fixed frame 3 inside the hollow fixed frame 3; two first rotating shafts 10, which are symmetrically disposed on the first slider 9 and fixedly connected to the first slider 9; two rotating plates 11, which are rotatably connected to the first rotating shafts 10 respectively; two second rotating shafts 12, which are respectively disposed at one end of the rotating plate 11 near the fixed block 5, rotatably connected to the rotating plate 11, and fixedly connected to the fixed block 5; and two connecting components, which are respectively disposed on the two fixed blocks 5.

[0032] During operation, the bidirectional lead screw 8 rotates, causing the two first sliders 9, which are helically connected to it, to move away from each other. This causes the rotating plate 11, which is rotatably connected to the first rotating shaft 10, to rotate, driving the fixed block 5, which is fixedly connected to the second rotating shaft 12, to slide within the fixed groove 4.

[0033] Reference Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, the connecting components include: a connecting frame 13, disposed on the fixing block 5 and fixedly connected to the fixing block 5; multiple connecting telescopic rods 29, which are evenly arranged within the connecting frame 13 and fixedly connected to the connecting frame 13; a pressure sensor 30, disposed at the top of the connecting telescopic rod 29 and fixedly connected to the connecting telescopic rod 29; a connecting spring 31, sleeved on the outer wall of the connecting telescopic rod 29 and fixedly connected to the inner wall of the connecting frame 13; a connecting block 32, disposed within the connecting frame 13, slidably connected to the connecting frame 13, and fixedly connected to the connecting spring 31 and the connecting telescopic rod 29; a connecting groove 33, formed on the side of the connecting block 32 away from the connecting spring 31; and a soft pad 34, disposed within the connecting groove 33 and fixedly connected to the connecting block 32.

[0034] During operation, the two connecting frames 13 fixedly connected to the fixing block 5 move closer to each other, causing the edge of the OLED screen to slide with the connecting groove 33 on the connecting block 32, which in turn causes the edge of the screen to contact the soft pad 34. When the edge of the screen contacts the soft pad 34, the connecting block 32 fixedly connected to the soft pad 34 slides into the connecting frame 13, causing the connecting telescopic rod 29 fixedly connected to the connecting block 32 to retract, which causes the connecting spring 31 to be compressed, generating elastic potential energy. At the same time, the pressure sensor 30 fixedly connected to the connecting telescopic rod 29 detects the compressive force generated by the connecting block 32.

[0035] Reference Figure 4 , Figure 6 and Figure 7 In a preferred embodiment, the cleaning mechanism includes: a cleaning block 15 disposed within the coating machine 1; a cleaning plate 35 disposed on the cleaning block 15 and fixedly connected to the cleaning block 15; a cleaning motor frame 16 disposed on the cleaning block 15 and fixedly connected to the cleaning block 15; a cleaning motor 17 fixedly connected to the cleaning motor frame 16; a first lead screw 18 fixedly connected to the output end of the cleaning motor 17 and rotatably connected to the cleaning block 15; and a sliding component disposed on the cleaning block 15.

[0036] When in operation, the cleaning motor 17 is started, which drives the first lead screw 18, which is fixedly connected to the output end of the cleaning motor 17, to rotate.

[0037] Reference Figure 4 , Figure 6and Figure 7 In a preferred embodiment, the sliding component includes: a sliding groove 19 formed on the cleaning block 15; a sliding block 20 disposed within the sliding groove 19, slidably connected to the sliding groove 19, and helically connected to the first lead screw 18; a transmission block 21 disposed within the coating machine 1 and fixedly connected to the cleaning plate 35; a transmission groove 22 formed on the transmission block 21; a drive block 23 disposed within the transmission groove 22 and slidably connected to the transmission groove 22; a lifting block 36, one end fixedly connected to the transmission block 21 and the other end fixedly connected to the cleaning block 15; and a rotating component. The rotating components include: two rotating plates 24, which are respectively fixedly mounted on the sliding block 20 and the driving block 23, and the two rotating plates 24 are symmetrically positioned; a rotating motor frame 25, which is mounted on the rotating plates 24 and fixedly connected to the rotating plates 24; a rotating motor 26, which is fixedly connected to the rotating motor frame 25; a rotating shaft 27, which is fixedly connected to the output end of the rotating motor 26 and rotatably connected to the two rotating plates 24; and a rotating brush 28, which is mounted on the rotating shaft 27 and fixedly connected to the rotating shaft 27.

[0038] During operation, the sliding block 20, which is helically connected to the first lead screw 18, slides in the sliding groove 19, causing the rotating plate 24, which is fixedly connected to the sliding block 20, to move. This causes the driving block 23, which is fixedly connected to the rotating plate 24, to slide in the transmission groove 22 on the transmission block 21. At the same time, the rotating motor 26 is started, causing the rotating shaft 27, which is fixedly connected to the output end of the rotating motor 26, to rotate on the rotating plate 24, causing the rotating brush 28, which is fixedly connected to the rotating shaft 27, to rotate.

[0039] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7 In a preferred embodiment, the lifting component includes: a lifting motor frame 37, which is mounted on the coating machine 1 and fixedly connected to the coating machine 1; a lifting motor 38, which is fixedly connected to the lifting motor frame 37; a transmission shaft 39, which is fixedly connected to the output end of the lifting motor 38 and rotatably connected to the coating machine 1; a lifting gear 40, which is fixedly connected to the transmission shaft 39; a lifting groove 41, which is opened inside the coating machine 1; and a lifting toothed plate 42, which is mounted inside the lifting groove 41, slidably connected to the lifting groove 41, meshes with the lifting gear 40, and is also fixedly connected to the lifting block 36.

[0040] During operation, the lifting motor 38 is started, which drives the transmission shaft 39, which is fixedly connected to the output end of the lifting motor 38, to rotate on the coating machine 1. This causes the lifting gear 40, which is fixedly connected to the transmission shaft 39, to rotate, which drives the lifting tooth plate 42, which meshes with the lifting gear 40, to slide in the lifting groove 41. This causes the lifting block 36, which is fixedly connected to the lifting tooth plate 42, to rise and fall, thereby driving the cleaning block 15 and the transmission block 21 to move until the height of the rotating brush 28 is aligned with the surface of the OLED screen.

[0041] Working principle: In use, the OLED screen is first placed on the fixed frame 3, and then the fixed motor 7 is started, which drives the bidirectional lead screw 8, which is fixedly connected to the output end of the fixed motor 7, to rotate on the fixed frame 3. This causes the two first sliders 9, which are helically connected to the bidirectional lead screw 8, to move away from each other, causing the rotating plate 11, which is rotatably connected to the first rotating shaft 10, to rotate. This causes the fixed block 5, which is fixedly connected to the second rotating shaft 12, to slide in the fixed groove 4, causing the connecting frame 13, which is fixedly connected to the fixed block 5, to move closer together. This causes the connecting block 32, which is slidably connected to the connecting frame 13, to move closer together, thereby allowing the OLED screen to move closer together. The edge of the screen contacts the soft pad 34. When the edge of the screen contacts the soft pad 34, it causes the connecting block 32, which is fixedly connected to the soft pad 34, to slide into the connecting frame 13, causing the connecting telescopic rod 29, which is fixedly connected to the connecting block 32, to retract. This causes the connecting spring 31 to be compressed, generating elastic potential energy. At the same time, the pressure sensor 30, which is fixedly connected to the connecting telescopic rod 29, detects the compressive force generated by the connecting block 32. When the compressive force reaches a preset value, the fixing motor 7 is turned off, thereby achieving the clamping and fixing of the screen. The pressure sensor 30 can be a TEConnectivity FX1901 series miniature pressure sensor. Next, when the screen needs cleaning, the lifting motor 38 is started first, driving the transmission shaft 39, which is fixedly connected to the output end of the lifting motor 38, to rotate on the coating machine 1. This causes the lifting gear 40, which is fixedly connected to the transmission shaft 39, to rotate, driving the lifting toothed plate 42, which meshes with the lifting gear 40, to slide in the lifting groove 41. This causes the lifting block 36, which is fixedly connected to the lifting toothed plate 42, to rise and fall, thereby moving the cleaning block 15 and the transmission block 21 until the height of the rotating brush 28 is aligned with the surface of the OLED screen, thus achieving height adjustment according to different OLED screen thicknesses. Then, the cleaning motor 17 is started. The first lead screw 18, which is fixedly connected to the output end of the cleaning motor 17, rotates, causing the sliding block 20, which is helically connected to the first lead screw 18, to slide in the sliding groove 19. This causes the rotating plate 24, which is fixedly connected to the sliding block 20, to move, causing the driving block 23, which is fixedly connected to the rotating plate 24, to slide in the transmission groove 22 on the transmission block 21. At the same time, the rotating motor 26 is started, causing the rotating shaft 27, which is fixedly connected to the output end of the rotating motor 26, to rotate on the rotating plate 24. This causes the rotating brush 28, which is fixedly connected to the rotating shaft 27, to rotate, thereby cleaning the surface of the OLED screen and avoiding affecting the adhesion of the backing adhesive.

[0042] It should be noted that each motor and pressure sensor can be controlled by a centralized controller installed outside the coating machine. This is well-known technology and will not be elaborated further.

[0043] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
