Description

Technical Field

[0001] The utility model relates to the technical field of backlight sources, and in particular to a device for laminating a light-shielding film around an LED screen of a backlight source. Background Art

[0002] The backlight is a light source located behind the liquid crystal display (LCD). Its luminous effect directly affects the visual effect of the liquid crystal display module (LCM). The backlight LED screen, that is, the LCD screen that uses LED as the backlight, has many advantages and a wide range of application scenarios.

[0003] However, when using traditional LED screen peripheral shading film bonding equipment, the narrow side length of the shading film needs to be changed, and the film cutting is inaccurate, resulting in the shading film not being able to completely fit the periphery of the LED screen, resulting in poor bonding effect. Utility Model Content

[0004] The utility model discloses a device for laminating a light-shielding film around an LED screen with a backlight source, aiming to solve the technical problem that when using the traditional light-shielding film laminating device around an LED screen, the narrow side length of the light-shielding film needs to be changed, the film is not cut accurately, and the light-shielding film cannot be completely laminated to the periphery of the LED screen, resulting in a poor laminating effect.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for laminating a light-shielding film around a backlight LED screen comprises a machine body, a light-shielding film body, a light-shielding film sheet, and an LED screen body, and further comprises:

Mounting blocks are provided on the outer walls of both sides of the machine body, and a unwinding roller and a winding roller are respectively provided on the outer walls of one side of the two mounting blocks. The shading film body is respectively used in conjunction with the unwinding roller, the conveying platform and the winding roller, and the cutter passes through the mounting hole and is used in conjunction with the shading film body.

[0009] In this solution, the shading film body is unwound by the unwinding roller and transported to the conveyor table, cut on the connecting frame and then reeled by the reeling roller. During the cutting process, the micrometer on one side of the connecting frame is used for precise positioning, so that the adjustment mechanism adjusts the two cutters to the appropriate position, and the shading film body is cut into shading film sheets by the cutter. Subsequently, the film is applied to the periphery of the LED screen through the film-applying mechanism. The micrometer has high precision, which makes the cutting more accurate, the required narrowness can be adjusted, and the fitting effect is better.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0021] The utility model discloses a backlight LED screen periphery shading film bonding device mainly used in scenarios where traditional LED screen periphery shading film bonding devices need to change the narrow side length of the shading film when used, and the film is not cut accurately, resulting in the shading film being unable to completely bond to the periphery of the LED screen, resulting in poor bonding effect.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A backlight LED screen peripheral shading film laminating device includes a body 1, a shading film body 5, a shading film sheet 21, and an LED screen body 9, and further includes:

[0023] Film sticking mechanism: used for sticking film on the LED screen body 9;

[0024] A conveying platform 2 is provided on one side of the top outer wall of the body 1, and the same connecting frame 16 is provided on both sides of the top outer wall of the conveying platform 2. A micrometer 22 is provided on the outer wall of one side of the connecting frame 16, and a mounting hole is opened on the top outer wall of the connecting frame 16. Two limit blocks 17 are provided on the top outer wall of the connecting frame 16, and a cutter 18 is provided on the bottom outer wall of the limit block 17. An adjustment mechanism is provided on the two limit blocks 17. Mounting blocks are provided on the outer walls of both sides of the body 1, and a unwinding roller 3 and a winding roller 4 are respectively provided on the outer walls of one side of the two mounting blocks. The shading film body 5 is used in conjunction with the unwinding roller 3, the conveying platform 2 and the winding roller 4 respectively, and the cutter 18 passes through the mounting hole and is used in conjunction with the shading film body 5.

[0025] During the specific working process, the shading film body 5 is unwound by the unwinding roller 3 and transported to the conveyor platform 2, and is cut at the position of the connecting frame 16. The cut shading film body 5 is wound up by the winding roller 4. During the cutting process, the micrometer 22 on one side of the connecting frame 16 is used for precise positioning, and the limit block 17 is positioned at the upper limit of the mounting hole, so that the adjustment mechanism adjusts the two cutters 18 to the appropriate position, and the shading film body 5 is cut into shading film sheets 21 by the cutter 18, and then the film is pasted on the periphery of the LED screen by the film pasting mechanism.

[0026] It should be noted that the angle setting of the blade enables the shading film body 5 to be better cut into the required shading film sheet 21, and the middle part of the shading film body 5 is not affected by the cutting. The conveyor table 2 transports it to the winding roller 4 for winding. After the shading film body 5 on the unwinding roller 3 is used up, the winding roller 4 can be replaced in the position of the unwinding roller 3 again, and the wound shading film body 5 can be reused without wasting resources.

[0027] Among them, the shading film body 5 is formed into a shading film piece 21 through a cutter 18. In this way, the peripheral film of the LED screen is narrower, and the shading film body 5 needs to be cut into a shading film piece 21 of the required narrowness by a blade, so that the cut shading film piece 21 can better fit the LED screen and have a good covering effect.

[0028] Reference Figure 3 and Figure 4 In a preferred embodiment, the adjustment mechanism includes a bidirectional threaded rod 19 provided on the inner walls of the two limit blocks 17, a knob 20 is provided at one end of the bidirectional threaded rod 19, and a limit ring is provided at the other end of the bidirectional threaded rod 19.

[0029] Specifically, by rotating the knob 20, the bidirectional threaded rod 19 is driven to rotate, so that the two cutters 18 move toward or away from each other, and the position of the cutter 18 is adapted to cut the shading film body 5 into the shading film sheet 21. The adjustment is simple and the adaptation effect is good.

[0030] The cutter 18 is used in conjunction with the micrometer 22. Thus, the cutter 18 is moved to a corresponding position according to the reading of the micrometer 22 to cut the light-shielding film body 5. The alignment is accurate and the cutting effect is good.

[0031] Reference Figure 1 and Figure 2 In a preferred embodiment, the film-sticking mechanism includes a connecting rod fixedly connected to the top outer wall of the body 1, and a connecting block 10 is fixedly connected to the top outer wall of the connecting rod. A groove is opened on the outer wall of one side of the connecting block 10, and an electric guide rail 12 is provided on the inner wall of the groove. Two sliders 13 are slidably connected to the inner wall of the electric guide rail 12, and an adapter block is provided on the outer wall of one side of the two sliders 13. A manipulator 14 is provided on the bottom outer wall of the adapter block, and a suction cup 15 is provided on the manipulator 14. Slide rails are provided on both sides of the top outer wall of the body 1, and two clamping blocks 6 are provided on the slide rails. The same clamping plate 7 is connected to the outer wall of one side of the two longitudinal clamping blocks 6, and a conveyor belt 8 is provided between the two clamping plates 7. The LED screen body 9 is located on the conveyor belt 8, and the same limiting groove 11 is opened on the top outer wall of the two clamping plates 7. The limiting groove 11 and the connecting frame 16 are located in the same direction.

[0032] Specifically, the LED screen body 9 moves on the conveyor belt 8. When it moves to the position of the limit slot 11, the electric guide rail 12 drives the two sliders 13 to move, so that the two manipulators 14 move to the position of the connecting frame 16. The suction cup 15 adsorbs the cut shading film 21, and then moves back to the position of the limit slot 11. At this time, the two manipulators 14 are folded relative to each other, so that the suction cup 15 is aligned with the two sides of the periphery of the LED screen body 9, and the shading film 21 is applied to the LED screen body 9. During this process, the position of the clamping block 6 and the clamping plate 7 can be changed according to the size of the LED screen body 9. The two can move on the slide rail to a position that is adapted to the transmission of the LED screen body 9, and then the corresponding transmission belt is installed between the two clamping plates 7 for better adaptation and unimpeded transmission of the LED screen body 9.

[0033] Among them, the suction cup 15 is used in conjunction with the shading film 21 and the LED screen body 9 respectively. In this way, the suction cup 15 absorbs the shading film 21, and then moves to the position of the LED screen body 9 to apply the film to the narrow sides of the LED screen body 9, and the adsorption and pasting are stable.

[0034] Working principle: When in use, at the position of the connecting frame 16, the shading film body 5 unwound by the unwinding roller 3 and transported to the conveyor table 2 is cut. According to the precise positioning of the micrometer 22, by rotating the knob 20, the bidirectional threaded rod 19 drives the two cutters 18 to move to the appropriate position, and cuts the shading film body 5 into corresponding shading film pieces 21. At this time, the LED screen body 9 is conveyed to the position of the limiting groove 11 on the conveyor belt 8, and the electric guide rail 12 drives the two sliders 13 to move, so that the two manipulators 14 move to the position of the connecting frame 16, and the suction cup 15 adsorbs the cut shading film piece 21, and then moves back to the position of the limiting groove 11. The two manipulators 14 are folded relative to each other, so that the suction cup 15 is aligned with the two sides of the periphery of the LED screen body 9, and the shading film piece 21 is applied to the LED screen body 9.

[0035] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
