[0002] Optical films cut by the cutting machine usually require preliminary inspection to check for defects such as dark spots, in order to ensure the quality of the films. The current inspection method is that after the films are output by the conveyor belt, the workers directly observe them with their naked eyes on the receiving table. Due to factors such as the influence of the workshop environment, and the need for careful observation by the workers, dark spots on the films are easily overlooked, which can cause eye fatigue and affect efficiency and inspection quality.

Detailed Implementation

[0018] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0019] refer to Figures 1 to 6 A diaphragm inspection device includes a frame on which a diaphragm conveyor belt 10 is mounted. A movable frame 20 is positioned below the front of the output end of the conveyor belt. An inspection light box 30, adjustable in tilt, is mounted on the upper side of the movable frame to receive the diaphragms. A light-transmitting plate 40 is mounted on the upper side of the inspection light box. A movable receiving table 50 is positioned in front of the inspection light box. Diaphragms output from the conveyor belt fall onto the inspection light box, allowing workers to inspect them for defects (such as dark spots) using the light. If no defects are found, the diaphragms are directly stacked on the receiving table. If defects are found, the diaphragms are removed and placed in a defective product storage area. The defective product storage area can be located beside the receiving table.

[0020] In this embodiment, to adjust the tilt angle of the inspection light box according to the height of the diaphragm conveyor belt, the lower front end of the inspection light box is hinged to the moving frame via a longitudinal pin 31. A hinge 32 is rotatably connected to the center of the bottom surface of the inspection light box, and an adjusting screw 33 is fixed to the lower end of the hinge. A fixed plate 21 is installed at the center of the upper end of the moving frame. The adjusting screw passes through a through hole 22 in the fixed plate, and an adjusting nut 34 is screwed onto the adjusting screw, abutting against the upper surface of the fixed plate. By rotating the adjusting nut, the height of the adjusting screw is controlled, thereby adjusting the tilt angle of the inspection light box.

[0021] In this embodiment, in order to better install the hinge, a hinge seat 35 is fixed on the bottom surface of the inspection light box, and the hinge seat is hinged to the hinge via a longitudinal rotating shaft 36.

[0022] In this embodiment, the inner diameter of the through hole is larger than the outer diameter of the adjusting screw, so that the adjusting screw can pass through the through hole even when tilted.

[0023] In this embodiment, to facilitate easier rotation of the adjusting nut by the operator, the fixing plate is U-shaped, with the upper ends of both sides of the fixing plate welded to the frame 23 at the top of the movable frame. The adjusting nut is a hand-tightening nut, allowing the operator to easily reach into the U-shaped fixing plate to rotate it. In another embodiment, a fastening nut, also a hand-tightening nut, is screwed onto the lower side of the adjusting screw located on the fixing plate.

[0024] In this embodiment, the bottom of the mobile frame is provided with casters 24 with a braking structure to facilitate the movement of the mobile frame.

[0025] In this embodiment, the inspection light box includes a rectangular box with an open top. An upward-facing light source 37 is installed inside the rectangular box. The light source is a cold light source, such as an LED light panel. A recessed stepped surface 38 is provided at the upper end of the rectangular box. A light-transmitting plate covers the upper end of the rectangular box and its periphery is in contact with the recessed stepped surface. The upper surface of the light-transmitting plate is flush with the upper end of the rectangular box, reducing obstruction to the diaphragm as it moves out of the inspection light box. The light-transmitting plate can be white. By shining the light of the LED lamp upward through the light-transmitting plate, dark spots, scratches, and other defects are more easily detected when the diaphragm moves onto the inspection light box, reducing the workload of the workers.

[0026] In this embodiment, a scratch-resistant layer 41 extending to the edge of the rectangular box is affixed to the upper surface of the lower end of the light-transmitting plate, which helps to prevent the diaphragm from being scratched when it slides out of the inspection light box. The thickness of the scratch-resistant layer is 0.5~1mm, which helps to reduce the obstruction encountered when the diaphragm slides out. The scratch-resistant layer can be adhesive tape.

[0027] In this embodiment, to facilitate the movement of the receiving platform, the receiving platform includes a movable base 51 with casters at the bottom, and the casters of the movable base have a braking structure. A receiving platform surface 52 is provided on the top of the movable base. A baffle plate 53 is fixed to one side and the front end of the receiving platform surface to prevent the film from detaching from the receiving platform surface. In another embodiment, the receiving platform surface is inclined, and the front end of the receiving platform surface and the side end with the baffle plate are both inclined downwards, so that the film entering the receiving platform surface can slide towards the inclined side, which helps to stack the film and ensure neat side stacking.

[0028] In this embodiment, in order to reduce the impact between the diaphragm and the side baffle, the inner side of the baffle is fitted with a buffer pad layer 54, and the surface of the buffer pad layer is fitted with a smooth layer extending to the receiving table surface.

[0029] In this embodiment, an ion fan 11 with multiple fans is longitudinally mounted on the upper side of the membrane conveyor belt to remove static electricity from the membrane. The ion fan can be a suspended ion fan, such as the KRB-205 model.

[0030] In this embodiment, the diaphragm conveyor belt may consist of multiple narrow conveyor belts 12 with a width not exceeding 15cm, spaced longitudinally.

[0031] In another embodiment, a visual lens can be installed on the upper side of the inspection light box. The visual lens is connected to a PC and takes a picture of the diaphragm. The picture is then transmitted to the PC to determine whether there are any defects on the diaphragm, thereby improving efficiency and reducing manual labor.

[0032] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0033] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0034] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0035] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
