Description

Technical Field

[0001] This invention relates to the field of optical film die-cutting and inspection technology, specifically to a high-yield OLED optical film die-cutting mold and its blade angle design. Background Technology

[0002] OLED optical film is a layer or multiple layers of functional film material that is bonded to the OLED screen panel. Optical film die-cutting mold is a device that cuts out optical film sheets of a complete and specific shape from the film material. After the optical film is cut, there is a possibility of air entering at the cut edge, which can easily cause air bubbles at the edge of the optical film. In addition, the surface of the optical film may also have scratches due to friction and process defects. Therefore, it is necessary to inspect the optical film to ensure its quality.

[0003] The existing optical film die-cutting equipment has the following drawbacks: Prior art CN210821015U discloses an optical film die-cutting device, which includes a peeling roller group, a cutting roller group, and a film-applying roller group. The cutting roller group includes a first cutting roller group, a second cutting roller group, and a third cutting roller group, which are arranged sequentially. The first cutting roller group includes a first cutter and a first drive roller shaft, with the first cutter meshing and rotating with the first drive roller shaft. The second cutting roller group includes a second cutter, a second drive roller shaft, and a third drive roller shaft, with the second drive roller shaft meshing and rotating with the third drive roller shaft, and the second cutter rotating in the same direction as the second drive roller shaft. The third cutting roller group includes a third cutter and a fourth drive roller shaft. Using this invention, no process film is used during the die-cutting of optical films, avoiding indentations on the cutting edges and improving the appearance of the cutting edges.

[0004] The aforementioned technologies do not include the inspection of the optical film after die-cutting. Defects in the optical film after die-cutting cannot be detected in a timely manner, requiring subsequent specialized inspection of optical film defects. This increases the process steps and reduces efficiency. Therefore, a high-yield OLED optical film die-cutting mold that can detect optical film defects is needed to solve this problem.

Guide frames are symmetrically installed on the inner side of the second frame. A plate is installed on the inner side of the guide frames. Multiple viewing angle detection mechanisms, including cameras, are provided at the bottom of the plate.

[0007] Preferably, a rectangular blade is installed at the bottom of the lifting plate, and springs are symmetrically installed at the bottom of the lifting plate. A pressure block is installed at one end of the springs, and the bottom of the pressure block penetrates through the bottom of the rectangular blade.

[0008] Preferably, an electric telescopic rod is installed on the bottom inner wall of the frame, a push rod is installed at the output end of the electric telescopic rod, a pressure sensor is installed at one end of the push rod, and a top plate is installed at the top input end of the pressure sensor, with the top plate located inside the die.

[0009] Preferably, a groove is provided on the left inner wall of the frame one, a cylinder one is installed on the left side of the frame one, a push plate is installed on the output end of the cylinder one, and the push plate is located inside the groove, and a through opening is provided on the right side of the frame one, and the through opening is connected to the frame two.

[0010] Preferably, two rotating rods are movably installed through the inner side of the second frame, and dust-collecting silicone is installed on the outer side of the rotating rods. Multiple motors are installed on the front of the second frame, and the output end of the motor is connected to one end of the rotating rod.

[0011] Preferably, a transparent plate is installed on the inner side of the second frame, and the transparent plate is located to the right of the dust-absorbing silicone, and a panel light is installed on the bottom inner wall of the second frame.

[0012] Preferably, a bolt is installed through the top of the guide frame, an electric telescopic rod two is installed on the top of the plate, a push rod two is installed at the output end of the electric telescopic rod two, a lifting frame is installed at one end of the push rod two, a silicone block is installed through the bottom of the lifting frame, and the silicone block is located to the right of the dust-collecting silicone block, and a non-stick film is installed at the bottom of the silicone block.

[0013] Preferably, a cylinder is installed on the front of the second frame, a movable frame is installed at the output end of the cylinder, a brush is installed through the bottom of the movable frame and the brush is located above the transparent plate, and a discharge port is opened through the back of the second frame.

[0014] Preferably, a plurality of movable rods are movably mounted through the back of the movable frame. A pressure plate is installed at one end of each movable rod, and the pressure plate is located inside the movable frame. A rod body is installed at one end of each movable rod, and springs are symmetrically installed on the front of each rod body. One end of each spring is connected to the back of the movable frame.

[0015] Preferably, it includes a rectangular blade, the inner wall of which is vertically upward and the outer wall of which is inclined upward.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after the optical film is die-cut, it is pushed onto a transparent plate. Then, by turning on the panel light, the optical film can be visually inspected by a camera, making it easy to detect defects such as scratches and bubbles on the optical film.

[0017] 2. In this invention, the operation of a cylinder drives a pusher plate to move to the right, pushing the optical film on the top plate into the opening. Then, it continues to push the film into two dust-absorbing silicone pads distributed vertically. The dust-absorbing silicone pads adsorb dust from the upper and lower surfaces of the optical film, thereby preventing dust on the optical film from affecting the accuracy of the camera's angle detection of the optical film.

[0018] 3. In this invention, the electric telescopic rod 2 drives the push rod 2 to move downward. The downward movement of the push rod 2 drives the lifting frame to move downward. The downward movement of the lifting frame drives the silicone block to move downward, thereby driving the non-stick film to move downward. After the non-stick film moves downward and contacts the optical film, the silicone block presses the optical film, thereby squeezing out the air bubbles at the edge of the optical film. The bottom of the silicone block is a convex spherical surface. When pressing down on the optical film, the silicone block first presses on the middle of the optical film. Then, after the silicone block is squeezed and deformed, it gradually squeezes towards the edge of the optical film, thereby squeezing out the air bubbles at the edge of the optical film from the inside out.

[0019] 4. When dust is detected on the transparent plate from the camera's perspective, the second cylinder drives the brush to move backward to clean the dust on the transparent plate, thereby avoiding the dust on the transparent plate affecting the accuracy of optical film defect detection.

Furthermore, the guide frame 24 provides guidance for the plate 26, enabling the plate 26 to move left and right.

Furthermore, after the optical film above the top plate 12 is die-cut, the top plate 12 moves down, causing the cut optical film to move down as well. Then, the controller 2 controls the cylinder 14 to work, and the cylinder 14 drives the push plate 15 to move to the right. The push plate 15 pushes the optical film above the top plate 12 into the opening 16, and then pushes it from the opening 16 into the inside of the two vacuuming silicone 19.

Multiple motors 20 are installed on the front side of the frame 2 17, and the output end of the motor 20 is connected to one end of the rotating rod 18. Furthermore, the controller 2 controls the motor 20 to work, the motor 20 drives the rotating rod 18 to rotate, the rotating rod 18 drives the dust-absorbing silicone 19 to rotate, the dust-absorbing silicone 19 drives the optical film located between the upper and lower dust-absorbing silicone 19 to move to the right above the transparent plate 21, and at the same time the dust-absorbing silicone 19 absorbs the dust on the upper and lower surfaces of the optical film.

[0029] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 An embodiment of the present invention provides: a high-yield OLED optical film die-cutting mold, wherein a transparent plate 21 is installed on the inner side of the frame 2 17, and the transparent plate 21 is located on the right side of the dust-absorbing silicone 19, and a panel light 22 is installed on the bottom inner wall of the frame 2 17. Furthermore, after the optical film moves above the transparent plate 21, the panel light 22 illuminates the bottom of the optical film, which facilitates the camera 39 to perform angle detection on the optical film and detect scratches and bubbles on the optical film.

[0030] Please see Figure 1 , Figure 2 , Figure 4 and Figure 7 An embodiment of the present invention provides: a high-yield OLED optical film die-cutting mold, wherein a bolt 25 is installed through the top of the guide frame 24, an electric telescopic rod 27 is installed on the top of the plate 26, a push rod 28 is installed at the output end of the electric telescopic rod 27, a lifting frame 29 is installed at one end of the push rod 28, a silicone block 30 is installed through the bottom of the lifting frame 29, and the silicone block 30 is located to the right of the dust-absorbing silicone 19, and a non-stick film 31 is installed at the bottom of the silicone block 30; Furthermore, bolt 25 is used to fix plate 26. After the optical film moves above the transparent plate 21, controller 2 controls electric telescopic rod 27 to work. Electric telescopic rod 27 drives push rod 28 to move downward. Push rod 28 moves downward, driving lifting frame 29 to move downward. Lifting frame 29 moves downward, driving silicone block 30 to move downward, thereby driving non-stick film 31 to move downward. After non-stick film 31 moves downward and contacts optical film, silicone block 30 presses the optical film, thereby squeezing out air bubbles at the edge of the optical film. The bottom of silicone block 30 is a convex spherical surface. When pressing down on the optical film, silicone block 30 first presses on the middle of the optical film. Then, after the silicone block 30 is squeezed and deformed, it gradually squeezes towards the edge of the optical film, thereby squeezing out air bubbles at the edge of the optical film from the inside out.

[0031] Please see Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9 An embodiment of the present invention provides a high-yield OLED optical film die-cutting mold. A cylinder 32 is installed on the front of the frame 17. A movable frame 33 is installed at the output end of the cylinder 32. A brush 34 is installed through the bottom of the movable frame 33 and is located above the transparent plate 21. A discharge port 23 is opened through the back of the frame 17. Multiple movable rods 35 are movably installed through the back of the movable frame 33. A pressure plate 36 is installed at one end of the movable rod 35 and is located inside the movable frame 33. A rod body 37 is installed at one end of the movable rod 35. Springs 38 are symmetrically installed on the front of the rod body 37 and one end of the springs 38 is connected to the back of the movable frame 33. Furthermore, after the camera 39 detects the viewing angle of the optical film, the controller 2 controls the cylinder 32 to work. The cylinder 32 drives the moving frame 33 to move backward, and the moving frame 33 drives the brush 34 to move backward. The brush 34 first pushes the optical film above the transparent plate 21 to the rear and discharges it from the discharge port 23. Furthermore, when it is necessary to replace the brush 34, the old brush 34 is taken out from the moving frame 33, and the new brush 34 is placed inside the moving frame 33. Then, the spring 2 38 applies a pulling force to the rod 37, thereby driving the movable rod 35 to move towards the brush 34, which in turn causes the pressure plate 36 to apply pressure to the brush 34 and squeeze and fix the brush 34. Furthermore, when the camera 39 detects dust on the transparent plate 21, the cylinder 32 drives the brush 34 to move backward to clean the dust on the transparent plate 21.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 10 The present invention provides an embodiment of a high-yield OLED optical film die-cutting mold, comprising a rectangular blade 6, wherein the inner wall of the rectangular blade 6 is vertically upward and the outer wall of the rectangular blade 6 is inclined upward; Furthermore, the vertically upward inner wall of the rectangular blade 6 can prevent the edges of the optical film inside the rectangular blade 6 from being scraped and layered due to the inclined inner wall of the blade when cutting the optical film, thereby preventing air bubbles from entering between the film layers inside the rectangular blade 6.

[0033] Working Principle: Before using the high-yield OLED optical film die-cutting mold, it should be checked whether there are any problems affecting its use. When the optical film is placed above the concave mold 3, the electric telescopic rod 9 drives the top plate 12 to move upward to support the bottom of the optical film. At the same time, the lifting plate 5 moves downward, driving the rectangular blade 6 and the pressure block 8 to move downward. The pressure block 8 presses the optical film under the pressure of the spring 7. Then, the rectangular blade 6 continues to move downward to die-cut the optical film, cutting the optical film off the entire optical film. Then, the top plate 12 moves downward, driving the optical film to move downward. Subsequently, the controller 2 controls the cylinder 14 to work, driving the push plate 15 to move to the right, pushing the optical film on the top plate 12 into the opening 16. Then, it continues to be pushed into the two dust-absorbing silicone 19 distributed vertically. The dust-absorbing silicone 19 adsorbs the dust on the upper and lower surfaces of the optical film, and at the same time, it moves the optical film to the right above the transparent plate 21, thus facilitating the camera 39 to view the optical film. Angle detection facilitates the controller 2's analysis of defects such as scratches and bubbles on the optical film. Then, the controller 2 controls the electric telescopic rod 27 to operate. The electric telescopic rod 27 drives the push rod 28 downwards, which in turn moves the lifting frame 29 downwards. The lifting frame 29 then moves the silicone block 30 downwards, thereby moving the non-stick film 31 downwards. After the non-stick film 31 contacts the optical film, the silicone block 30 presses against it, squeezing out bubbles from the edges of the optical film. The silicone block 30 has a convex spherical bottom. When pressing down on the optical film, the silicone block 30 first presses against the center of the film, then, after being deformed, gradually presses towards the edges, squeezing out bubbles from the inside out. After the camera 39 completes its inspection of the optical film, the cylinder 32 drives the moving frame 33 to move backwards. The moving frame 33 then moves the brush 34 backwards. The brush 34 first pushes the optical film above the transparent plate 21 backwards and discharges it from the discharge port 23.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the rights involved.
