Description

Technical Field

[0001] This utility model relates to the field of backlight wrapping technology, and in particular to an automatic backlight wrapping machine. Background Technology

[0002] A backlight is a light source located behind an LCD display, and its luminous effect directly affects the visual effect of the LCD module. The LCD itself does not emit light; it displays graphics or is the result of its modulation of light. A backlight mainly consists of a light source, a light guide plate, optical modules, and structural components.

[0003] Backlights need to be wrapped with film during packaging. Conventional wrapping is mainly done manually. After cutting the film to the required length, the film is carefully and evenly applied around the backlight. However, this method of wrapping is inefficient. Utility Model Content

[0017] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a backlight-based automatic film wrapping machine according to this utility model. Figure 2 This is a schematic diagram of the structure of the driving component of this utility model.

[0018] This utility model provides an automatic backlight wrapping machine, including a base 101, a film holder 102, a film roller 103, and a fixed frame 104, and also includes a wrapping device. The wrapping device includes a first chuck 105, a second chuck 106, a movable frame 107, a guide frame 108, a pushing component, and a cutting component. The cutting component includes a mounting frame 111, a cutter 112, a cutting plate 113, and an overhead component. The overhead component includes a support rod 115 and a base plate 116. The pushing component includes a pushing screw 117, a fixed plate 118, and a rotating component. The rotating component includes a rotating rod 119 and a rotating disk 120. The aforementioned solution solves the problem that backlights need to be wrapped with film during packaging. Conventional wrapping is mainly done manually, where the film paper is cut to the required length and then carefully and evenly applied around the backlight. However, this method is inefficient. The aforementioned solution can be used in the scenario of wrapping film for backlights.

[0019] In this embodiment, by attaching one end of the film paper on the film roller 103 to the backlight, the backlight is rotated by the first chuck 105, so that the film paper is automatically wound around the backlight, thereby completing the automatic film winding of the backlight and improving the film winding efficiency of the backlight.

[0020] The first chuck 105 is rotatably mounted on the fixed frame 104, and has a first slot 109. The guide frame 108 is fixedly mounted on the base 101, and the movable frame 107 is slidably mounted on the guide frame 108 via the pushing assembly. The second chuck 106 is rotatably mounted on the movable frame 107, and has a second slot 110. The cutting assembly is disposed on the base 101. The axes of the first chuck 105 and the second chuck 106 coincide. The first chuck 105 is driven by a motor. The first slot 109 is the same size as the second slot 110. The guide frame 108 has a U-shaped structure, and the movable frame 107 has an L-shaped structure. In use, the movable frame 107 is pushed by the pushing component to move the second slot 106, so that the backlight is stuck in the first slot 109 and the second slot 110. By attaching one end of the film paper on the film roller 103 to the backlight, the backlight is rotated by the first slot 105, so that the film paper is automatically wound around the backlight, thereby completing the automatic film winding of the backlight and improving the film winding efficiency of the backlight.

[0021] Secondly, the cutting plate 113 is mounted on the base 101 via the overhead component, and the cutting plate 113 is provided with a cutting groove 114; the mounting bracket 111 is fixedly mounted on the cutting plate 113, and the mounting bracket 111 is provided with a cylinder 121, and the cutter 112 is fixedly connected to the output end of the cylinder 121. The cutting plate 113 is a flat plate structure, the cutting groove 114 is a V-shaped structure, the mounting bracket 111 is a U-shaped structure, and the cutter 112 is also a V-shaped structure. The cylinder 121 drives the cutter 112 to move down into the cutting groove 114, thereby cutting the film paper.

[0022] Furthermore, the chassis 116 is fixedly mounted on the base 101; the support rod 115 is fixedly mounted on the chassis 116 and fixedly connected to the cutting plate 113. The chassis 116 is welded to the support rod 115, which is a cylindrical structure. Through the cooperation of the chassis 116 and the support rod 115, the cutting plate 113 is raised to a certain height.

[0023] Furthermore, the fixed plate 118 is fixedly mounted on the guide frame 108; the push screw 117 is threaded through the fixed plate 118 and rotatably connected to the second chuck 106; the rotating component is disposed on the push screw 117, the fixed plate 118 is provided with a threaded hole, the push screw 117 is parallel to the axis of the second chuck 106, and the rotating component drives the push screw 117 to rotate, so that the push screw 117 pushes the movable frame 107 during the rotation.

[0024] Finally, the rotating disk 120 is fixedly mounted on the push screw 117; the rotating rod 119 is fixedly mounted on the rotating disk 120, the rotating disk 120 is welded to the end of the push screw 117, and the rotating rod 119 is located at an eccentric position on the rotating disk 120. The rotating rod 119 drives the rotating disk 120 to rotate, thereby facilitating the rotation of the push screw 117.

[0025] In this embodiment, during use, one side of the backlight is first engaged in the first slot 109 on the first chuck 105. Then, the rotating rod 119 drives the rotating disk 120 to rotate, causing the rotating disk 120 to drive the push screw 117 to rotate. During rotation, the push screw 117 pushes the movable frame 107, causing the movable frame 107 to move the second chuck 106 closer to the first chuck 105, until the other side of the backlight is engaged in the second slot 110 on the second chuck 106. The film paper on the film roller 103 is then passed between the cutter 112 and the cutting plate 113, with one end of the film paper attached to the backlight. The motor then drives the first chuck 105 to rotate, which in turn drives the backlight to rotate, causing the film paper to automatically wrap around the backlight. After the wrapping is completed, the cylinder 121 is activated to push the cutter 112 downward and into the cutting groove 114, cutting the film paper and completing the wrapping of the backlight. This completes the automatic wrapping of the backlight and improves the wrapping efficiency of the backlight.
