Description

Technical Field

[0001] This utility model relates to the field of backlight processing technology, and in particular to a film-applying auxiliary fixture for backlight production. Background Technology

[0002] Existing film application devices typically require manual application of the protective film to the surface of the backlight structure. This process is cumbersome, time-consuming, and inefficient. Furthermore, some film application devices lack a roller pressing structure, which can lead to air bubbles after film application, affecting the use of the backlight structure and resulting in poor performance.

[0003] Existing technology CN216485853U discloses a backlight film application device, including an operating table and a control switch disposed at the front end of the operating table. An upper frame is fixedly installed on the upper end of the operating table, a frame is disposed on one side of the upper frame, and an adsorption component is disposed on one side of the frame. A roller pressing structure is also installed on the upper end of the operating table. The roller pressing structure includes a support rod disposed on the upper end of the operating table and a mounting frame disposed on the upper end of the support rod, as well as a side groove formed on one side of the mounting frame. A cylinder is fixedly installed inside the side groove, and the other end of the cylinder is connected to a linkage block. A mounting plate is disposed on the outer side of the linkage block, and a roller is disposed on one side of the mounting plate. The outer wall is fitted with an outer cylinder, which is a ring-shaped structure made of rubber. During use, the operator places the backlight structure on the operating table and turns on the motor to rotate the lead screw. There are two sets of threaded limit plates with opposite threads. As the lead screw rotates, the two sets of threaded limit plates move closer to each other, thus clamping and limiting the backlight structure for subsequent film application. The roller can move the outer cylinder to roll and press the backlight structure against the protective film, facilitating film application and removing air bubbles, resulting in good performance.

[0004] However, when using the above method, the height of the external tube is fixed during the film application process of the backlight structure, which means that only backlights of the same thickness can be rolled, resulting in inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to provide a film-applying auxiliary fixture for backlight production, which enables the height of the external cylinder to be adjusted according to the thickness of the backlight structure during the rolling process, thereby facilitating the adaptation of backlights of different thicknesses.

[0006] To achieve the above objectives, this utility model provides a backlight production film-applying auxiliary fixture, including an operating table, a mounting frame, a roller, and an external cylinder. The mounting frame is disposed on the operating table, the roller is slidably disposed on the mounting frame, and the external cylinder is sleeved on the outer wall of the roller. It also includes an adjustment device.

[0007] The adjustment device includes a mounting column, a movable column, a drive assembly, and an auxiliary assembly. The mounting column is fixedly connected to the operating table and located on one side of the operating table. The movable column is slidably connected to the mounting column and fixedly connected to the mounting frame. The drive assembly is disposed on the operating table, and the auxiliary assembly is disposed on the movable column.

[0008] The drive assembly includes a mounting bracket and a drive motor. The mounting bracket is fixedly connected to the operating table and located on one side of the operating table; the drive motor is fixedly connected to the mounting bracket and located on one side of the mounting bracket.

[0009] The drive assembly further includes a drive shaft and a drive plate. The drive shaft is fixedly connected to the output end of the drive motor. The drive plate is fixedly connected to the moving column and is located on the side of the moving column closer to the drive shaft.

[0010] The outer surface of the drive shaft has drive teeth, and the drive plate has external teeth on the side near the drive shaft, and the drive teeth mesh with the external teeth.

[0011] The auxiliary components include a limiting plate and a synchronization controller. The limiting plate is fixedly connected to the moving column and is located on one side of the moving column. The synchronization controller is mounted on the mounting frame and is electrically connected to the drive motor.

[0012] This utility model discloses a film-applying auxiliary fixture for backlight production, comprising an operating table, a mounting frame, a roller, an outer cylinder, and an adjustment device. The adjustment device includes a mounting column, a moving column, a drive assembly, and an auxiliary assembly. During the rolling process of the backlight structure, the mounting frame is connected to the operating table via the mounting column and the moving column. By setting the drive assembly on the operating table, the drive assembly drives the moving column to move vertically on the mounting column, thereby adjusting the mounting angle of the mounting frame. This allows the height of the outer cylinder to be adjusted according to the thickness of the backlight structure, facilitating adaptation to backlight structures of different thicknesses.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The first embodiment of this application is as follows:

[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the film-applying auxiliary fixture used in backlight production. Figure 2 This is an overall front view of the film-applying auxiliary fixture used in backlight production. Figure 3 This is a schematic diagram of the regulating device. Figure 4 This is a schematic diagram of the drive teeth and external teeth. This utility model provides a film-applying auxiliary fixture for backlight production: it includes an operating table 101, a mounting frame 102, a roller 103, an external cylinder 104, and an adjustment device. The adjustment device includes a mounting column 105, a moving column 106, a drive assembly, and an auxiliary assembly. The drive assembly includes a mounting bracket 107, a drive motor 108, a drive shaft 109, and a drive plate 110. The outer surface of the drive shaft 109 has drive teeth 111, and the drive plate 110 has external teeth 112 on the side near the drive shaft 109. The auxiliary assembly includes a limiting plate 113 and a synchronization controller 114. The aforementioned solution solves the problem that the fixed height of the outer tube 104 during the backlight structure film application process results in the inconvenience of only being able to roll backlights of the same thickness. It is understood that the aforementioned solution can be used to adjust the height of the outer tube 104 according to the thickness of the backlight structure during the roll forming process, thereby facilitating the adaptation of backlights of different thicknesses. It can also be used to enable synchronous adjustment at both ends of the mounting frame 102.

[0022] In this specific embodiment, the mounting frame 102 is disposed on the operating table 101, the roller 103 is slidably disposed on the mounting frame 102, and the outer wall of the roller 103 is sleeved with the outer cylinder 104. A side groove is opened on the side of the mounting frame 102, and a cylinder is disposed inside the side groove. The roller 103 is disposed outside the cylinder, and the outer wall of the roller 103 is sleeved with the outer cylinder 104. The outer cylinder 104 has a circular structure and is a component made of rubber material. When the backlight is placed on the operating table 101, the outer cylinder 104 can roll and press the backlight structure and the protective film, which facilitates the application of the film.

[0023] The mounting column 105 is fixedly connected to the operating table 101 and located on one side of the operating table 101. The movable column 106 is slidably connected to the mounting column 105 and fixedly connected to the mounting frame 102. The driving component is disposed on the operating table 101, and the auxiliary component is disposed on the movable column 106. The mounting column 105 is fixed to the operating table 101, and the movable column 106 is slidably disposed outside the mounting column 105. The top end of the movable column 106 is fixed to the lower surface of the mounting frame 102. The movable columns 106 are disposed on both sides of the lower surface of the mounting frame 102. The movable columns 106 are driven by the driving component, allowing them to move on the mounting column 105, thereby adjusting the distance between the movable column 106 and the mounting column 105. The movable column 106 drives the mounting frame 102 to adjust its height, thereby adjusting the height of the external cylinder 104 to adapt to backlight structures of different thicknesses. The auxiliary component restricts the movement of the movable column 106 to prevent it from detaching from the mounting column 105. During the rolling process of the backlight structure, the mounting frame 102 is connected to the operating table 101 via the mounting column 105 and the movable column 106. By setting the driving component on the operating table 101, the driving component drives the movable column 106 to move vertically on the mounting column 105, so that the movable column 106 drives the mounting frame 102 to adjust its installation angle. This allows the height of the external cylinder 104 to be adjusted according to the thickness of the backlight structure, making it easy to adapt to backlight structures of different thicknesses.

[0024] Secondly, the mounting bracket 107 is fixedly connected to the operating table 101 and located on one side of the operating table 101; the drive motor 108 is fixedly connected to the mounting bracket 107 and located on one side of the mounting bracket 107; the drive shaft 109 is fixedly connected to the output end of the drive motor 108; the drive plate 110 is fixedly connected to the moving column 106 and located on the side of the moving column 106 near the drive shaft 109; the drive teeth 111 mesh with the external teeth 112; the mounting bracket 107 is fixed to the left side of the operating table 101; the drive motors 108 are fixed on both sides of the mounting bracket 107; the output end of the drive motor 108 passes through one side of the mounting bracket 107 and is fixed to the drive shaft 109; the two drive shafts 109 are respectively located below the mounting frame 102. The movable columns 106 are located away from each other on one side. The length of the drive shaft 109 is greater than the distance between the two movable columns 106 below the two mounting frames 102. The outer surface of the drive shaft 109 is provided with drive teeth 111. The drive plate 110 is fixed to the side of the movable column 106 near the drive shaft 109, and the outer surface of the drive plate 110 is provided with external teeth 112. When the drive motor 108 starts, it drives the drive shaft 109 to rotate. Under the meshing action of the drive teeth 111 on the outer surface of the drive shaft 109 and the external teeth 112, the drive plate 110 is driven to move. The drive plate 110 drives the movable column 106 to move on the mounting column 105, thereby allowing the movable column 106 to drive the mounting frame 102 to adjust its height.

[0025] Meanwhile, the limiting plate 113 is fixedly connected to the moving column 106 and located on one side of the moving column 106; the synchronization controller 114 is mounted on the mounting bracket 107 and is electrically connected to the drive motor 108. The limiting plate 113 is fixed to the front side of the bottom end of the moving column 106. The limiting plate 113 is located below the drive shaft 109. The setting of the limiting plate 113 restricts the movement of the moving column 106, so that the bottom end of the moving column 106 moves to the drive shaft 109. When the position is below 9, the limiting plate 113 prevents the moving column 106 from detaching from the mounting column 105. The synchronous controller 114 (which is prior art and therefore not described in detail in this application) is fixed at the center of the left side of the mounting frame 107. The synchronous controller 114 is electrically connected to the two drive motors 108. The synchronous controller 114 enables the two drive motors 108 to start synchronously, thereby allowing simultaneous height adjustment of both ends of the mounting frame 102.

[0026] When using the backlight production film-applying auxiliary fixture of this embodiment, during the rolling process of the backlight structure, the mounting frame 102 is connected to the operating table 101 through the mounting column 105 and the moving column 106. By setting the driving component on the operating table 101, the driving component drives the moving column 106 to move vertically on the mounting column 105, so that the moving column 106 drives the mounting frame 102 to adjust the mounting degree. This allows the height of the outer cylinder 104 to be adjusted according to the thickness of the backlight structure, making it easy to adapt to backlight structures of different thicknesses.
