Description

Technical Field

[0001] This utility model relates to a positioning platform for optical diaphragm folding earphones. Background Technology

[0002] Currently, optical films are widely used in display devices, especially liquid crystal displays (LCDs). As a passive light-emitting element, the LCD screen itself does not emit light; instead, it is illuminated by the backlight system. The backlight system mainly consists of a light source, a light guide plate, optical films, and a plastic frame. The light guide plate converts the incoming light source into a surface light source, thereby illuminating the entire LCD screen. Furthermore, by placing optical films on the light guide plate, it serves to uniformly distribute light and converge light at a wide angle for frontal viewing.

[0003] Optical films typically have folded lugs on their edges to facilitate installation and removal. Currently, folding optical films involves manually placing them on a folding lug stand, folding them using the lug stand, and then manually removing the folded film and placing it on a tray before transporting it to the next workstation for further processing. Because this process requires manual positioning and removal of the folded film, it is time-consuming and slows down the overall production schedule. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a positioning and placement platform for optical diaphragm folding earphones. The platform is reasonably designed and uses a combination of fixed positioning mechanism and movable positioning mechanism to position the optical diaphragm. At the same time, after the earphone is folded, the conveyor belt rises and lifts the folded optical diaphragm. The conveyor belt then transports the optical diaphragm to the next work station, reducing manual labor, improving production efficiency, and facilitating specialized production work.

[0005] This utility model is implemented using the following scheme: a positioning and placement platform for optical diaphragm folding earphones: including a mounting base, a worktable mounted on the mounting base, a conveyor belt that slides and rises within the worktable on the mounting base, a fixed positioning mechanism is provided on one side of the worktable along the conveyor belt conveying direction on the mounting base, and a movable positioning mechanism is provided on the other side, and an ear-folding guide component is provided on one edge of the movable positioning mechanism on the worktable.

[0009] Furthermore, the folded ear guide assembly includes a folded ear guide plate, which is slidably mounted on the mounting base and abuts against the side of the workbench. The mounting base is equipped with a clamping and sliding mechanism for driving the sliding of the folded ear guide plate. The side of the folded ear guide plate away from the workbench is an inclined surface, and the angle between the inclined surface of the folded ear guide plate and the upper surface is an acute angle.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] like Figure 1-7 As shown, a positioning and placement platform for optical diaphragm folding earpieces includes a mounting base 1, a worktable 2 mounted on the mounting base, a conveyor belt 3 slidably connected to the mounting base within the worktable, a fixed positioning mechanism 4 on one side of the worktable along the conveyor belt's transport direction, and a movable positioning mechanism 5 on the other side of the mounting base, and a folding ear guide assembly 6 on one edge of the movable positioning mechanism on the worktable. In use, the optical diaphragm 32 can be placed on the worktable manually or by a robotic arm, and then positioned by the combined action of the fixed and movable positioning mechanisms. After positioning, the folding ear line of the optical diaphragm is located at the edge of the folding ear guide assembly. Then, the folding ear of the optical diaphragm is bent by the folding ear mechanism. After bending, the conveyor belt rises, lifting the bent optical diaphragm, and the conveyor belt transports the optical diaphragm to the next workstation. Of course, the conveyor belt can also be connected to other conveyor belts to transfer the optical diaphragm out, realizing the transport.

[0028] In this embodiment, to position the optical film away from the folded area, the fixed positioning mechanism includes at least two fixed posts 7, which are mounted on the mounting base and spaced apart beside the worktable. To position the optical film on the bent side, the movable positioning mechanism includes at least two movable posts 8, which are slidably mounted on the mounting base. The sliding direction of the movable posts is perpendicular to the side of the worktable, i.e., towards the bent side of the optical film. A horizontal push rod 9 is horizontally placed on the upper end of each movable post, and a top block 10 is provided on one end of the horizontal push rod. The top block can be made of rubber or silicone, and the top block of the horizontal push rod faces the worktable, i.e., towards the bent side of the optical film. The base is equipped with a drive mechanism 11 for sliding the movable column. In use, the optical film is placed on the worktable manually or by a robotic arm. Then, the drive mechanism drives the movable column to slide toward the worktable, thereby causing the top block at the end of the horizontal push rod to abut against the optical film. This causes the side of the optical film away from the folding lug to abut against the fixed column, exposing the folding lug area on the bent side of the optical film to the folding lug guide assembly, which facilitates subsequent folding operations. No additional positioning is required on the left and right sides of the folding lug side of the optical film, as long as these two sides do not exceed the range of the worktable. In this way, the area of ​​the optical film will definitely be on the edge of the folding lug guide assembly. Therefore, only the positioning of the optical film away from the folding lug area and the folding lug side is required.

[0029] In this embodiment, in order to realize the driving mechanism to drive the movable column, the driving mechanism includes a horizontal sliding plate 12, the movable column is installed on the horizontal sliding plate at intervals, a guide rail 13 is installed on the mounting base corresponding to the horizontal sliding plate, a guide groove 14 is provided on the horizontal sliding plate corresponding to the guide rail, and a driving cylinder 15 for driving the horizontal sliding plate to slide is also installed on the mounting base. A fixing block 33 connected to the horizontal sliding plate can be installed on the extension end of the driving cylinder. In use, the horizontal sliding plate is driven to move along the guide rail by the driving cylinder to realize the sliding of the movable column.

[0030] In this embodiment, to achieve the folded ear, the folded ear guide assembly includes a folded ear guide plate 16, which is slidably mounted on the mounting base and abuts against the side of the worktable. The mounting base is equipped with a clamping and sliding mechanism for driving the sliding of the folded ear guide plate. The side of the folded ear guide plate away from the worktable is an inclined surface, and the angle between the inclined surface and the upper surface of the folded ear guide plate is an acute angle. After the optical film is positioned, the folded ear area is exposed at the upper end of the folded ear guide plate. By pressing down along the inclined surface with the folding earpiece, the folded ear area is pressed down along the inclined surface, and finally the folded ear is formed. The folded ear mechanism can use an existing folding earpiece.

[0031] In this embodiment, since the folded ear forms a hook-like structure, the optical film is not easily detached from the workpiece. Therefore, a folded ear guide plate is needed to push the folded ear away, making it easier for the optical film to be lifted after the conveyor belt rises. The specific structure is as follows: The clamping and sliding mechanism includes two symmetrically horizontally arranged clamping and sliding cylinders 17. The clamping and sliding cylinders are fixed on the mounting base, and the telescopic ends of the clamping and sliding cylinders face the folded ear guide plate. A connecting block 18 is provided on the telescopic end of the clamping and sliding cylinder. A connecting groove 19 is provided on the folded ear guide plate, and the connecting block is fixed in the connecting groove. At the same time, the clamping and sliding mechanism also includes a limiting slide rail 20. The limiting slide rail is parallel to the telescopic direction of the clamping and sliding cylinder. A limiting groove 21 is provided under the folded ear guide plate corresponding to the limiting slide rail. In use, the sliding of the folded ear guide plate is achieved by the cooperation of the limiting slide rail and the clamping and sliding cylinder.

[0032] In this embodiment, to achieve conveying, the conveyor belt includes support frames 22 disposed on the front and rear sides of the worktable. Parallel conveyor rollers 23 are rotatably connected to the support frames. Several conveyor belts 24 are disposed around the two parallel conveyor rollers. A relief groove 25 is provided on the worktable corresponding to the conveyor belt body. The relief groove horizontally penetrates the worktable. The conveyor belt body located in the relief groove area is completely within the relief groove. A lifting mechanism 26 for driving the support frame to rise and fall is installed in the mounting base. A motor 27 for driving the parallel conveyor rollers to rotate is disposed on the outside of one of the support frames. When folding the ears, the conveyor belt body located in the relief groove area is completely within the relief groove and does not contact the optical film. After folding, the lifting mechanism lifts the support frames on both sides, causing the conveyor belt to rise and lift the optical film. Then the motor starts, driving the conveyor belt to move, realizing the output of the optical film.

[0033] In this embodiment, in order to realize the lifting of the support frame, the lifting mechanism includes a lifting cylinder 28 corresponding to the straight support frame. The lifting cylinder is installed under the platform of the mounting base. The platform of the mounting base is provided with a clearance hole 29 for the end of the lifting cylinder to extend upward. The telescopic end of the lifting cylinder is fixed under the support frame.

[0034] In this embodiment, in order to assist the lifting and lowering of the support frame, at least one lifting column 30 parallel to the lifting cylinder is provided under the support frame, and a lifting clearance hole 31 is provided on the mounting base corresponding to the lifting column.
