Description

Technical Field

[0001] This utility model belongs to the field of LED backlight module production technology, and in particular relates to an LED backlight module coating equipment. Background Technology

[0002] As one of the core components of LCD display devices, LED backlight modules need to have protective or optical films laminated onto their surfaces through a coating process to improve surface hardness, scratch resistance, and optical performance.

[0003] Currently, the pressure rollers of existing laminating equipment are usually fixed or only have a simple pressing function. For backlight modules with inclined edges, the pressing trajectory at the starting and ending ends cannot match the module contour, causing film edge accumulation or sudden tension changes. In addition, when the surface of the backlight module is uneven, traditional pressure rollers cannot be adjusted accordingly, which can easily lead to local wrinkles or stretching of the film, affecting product quality.

[0004] To address the aforementioned issues, this application proposes an LED backlight module coating device. Utility Model Content

[0005] The purpose of this invention is to provide an LED backlight module coating equipment, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an LED backlight module coating equipment, comprising a horizontal plate, characterized in that it further comprises: a pressing assembly disposed below the horizontal plate and capable of reciprocating in the horizontal direction, the pressing assembly being mounted below a translation seat via a hinge structure; and a spring disposed between the pressing assembly and the translation seat, the two ends of the spring being respectively fixed with connecting seats, the pressing assembly and the translation seat being respectively fixed with fixing seats, and the fixing seats being detachably connected to the connecting seats.

[0008] Furthermore, the pressing assembly includes a pressure roller and a mounting base, with the pressure roller rotatably mounted within the mounting base.

[0009] Furthermore, a fixing block is fixedly provided on the top surface of the mounting base, and the fixing block is hinged to the hinge base. The top surface of the hinge base is fixedly connected to the translation base through a connecting block.

[0010] Furthermore, the fixing seat is a rectangular block structure, one of the fixing seats is fixedly connected to the top surface of the mounting seat, the fixing seat has limit grooves on both sides, the connecting seat is U-shaped, and the shape of the side walls of the connecting seat is adapted to the limit grooves.

[0011] Furthermore, both the fixed base and the connecting base are provided with mounting holes and are fixedly connected by bolts.

[0012] Furthermore, two vertical plates are fixedly mounted on the bottom surface of the horizontal plate, and a screw is rotatably installed between the vertical plates. The screw is threadedly connected to the sliding seat, and the bottom surface of the sliding seat is fixedly connected to the translation seat. A motor is fixedly mounted on the side of one of the vertical plates, and the output end of the motor is fixedly connected to the screw.

[0013] Furthermore, a guide rod is fixed between the vertical plates, and the guide rod slides with the sliding seat.

[0014] Furthermore, the outer surface of the pressure roller is covered with a layer of elastic material.

[0015] This utility model has the following beneficial effects:

[0016] This utility model uses a hinge structure to install the pressing component under the translation seat. The pressing component can rotate around the hinge point, which can not only adapt to the unevenness or height difference of the backlight module surface, but also adapt to the coating requirements of backlight components of different heights.

[0017] This invention uses a spring to restrict the pressing assembly, preventing it from swinging arbitrarily. At the same time, when the pressing assembly moves horizontally, the spring applies a continuous and flexible pressing force to the film through the pressing assembly, so that the pressure roller always adheres to the film and substrate surfaces with constant pressure during the film coating process. It can also avoid film wrinkles or module damage caused by rigid extrusion.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1 to 5 As shown, this utility model is an LED backlight module coating equipment, including a horizontal plate 1, and further including: a pressing component 2, which is disposed below the horizontal plate 1 and can reciprocate in the horizontal direction, the pressing component 2 is mounted below the translation seat 6 through a hinge structure; a spring 9, which is disposed between the pressing component 2 and the translation seat 6, with connecting seats 8 fixedly provided at both ends of the spring 9, and fixing seats 7 fixedly provided on the pressing component 2 and the translation seat 6 respectively, and the fixing seats 7 are detachably connected to the connecting seats 8 respectively;

[0030] This embodiment provides an LED backlight module coating equipment. The pressing component 2 can rotate to a certain extent under the translation seat 6, which can not only be applied to backlight modules of different heights, but also adapt to the unevenness of the backlight module surface. The pressing component 2 can move horizontally to evenly press the film material onto the backlight module surface. The spring 9 is used to provide buffering and sufficient pressing force. The spring 9 can be easily replaced through the detachable connection of the fixing seat 7 and the connecting seat 8.

[0031] The pressing assembly 2 includes a pressure roller 201 and a mounting base 202. The pressure roller 201 is rotatably mounted in the mounting base 202. The pressure roller 201 presses the film material onto the surface of the backlight module by rolling, reducing friction and ensuring that the film material is flat and adhered.

[0032] The mounting base 202 has a fixed block 3 on its top surface, and the fixed block 3 is hinged to the hinge base 4. The top surface of the hinge base 4 is fixed to the translation base 6 through the connecting block 5. This hinge structure allows the pressing assembly 2 to rotate around the hinge point and change the height of the pressure roller 201.

[0033] The fixing seat 7 is a rectangular block structure. One of the fixing seats 7 is fixedly connected to the top surface of the mounting seat 202. Limiting grooves 701 are opened on both sides of the fixing seat 7. The connecting seat 8 is U-shaped, and the shape of the side walls of the connecting seat 8 is adapted to the limiting grooves 701. The fixing seat 7 and the connecting seat 8 are snapped together by the cooperation of the limiting grooves 701 and the side walls of the connecting seat 8.

[0034] Both the fixed base 7 and the connecting base 8 are provided with mounting holes and are fixedly connected by bolts. The bolt connection method is simple and reliable, easy to disassemble and assemble, and convenient to disassemble and replace the spring 9.

[0035] Two vertical plates 101 are fixedly mounted on the bottom surface of the horizontal plate 1, and a screw 11 is rotatably mounted between the vertical plates 101. The screw 11 is threadedly connected to the sliding seat 10, and the bottom surface of the sliding seat 10 is fixedly connected to the translation seat 6. A motor 13 is fixedly mounted on the side of one of the vertical plates 101, and the output end of the motor 13 is fixedly connected to the screw 11. The screw 11 is set parallel to the horizontal plane. The motor 13 is a forward and reverse motor used to drive the screw 11 to rotate, and further drive the translation seat 6 to move horizontally through the sliding seat 10, thereby driving the pressing assembly 2 to move for the coating work.

[0036] Among them, a guide rod 12 is fixed between the vertical plates 101, and the guide rod 12 slides with the sliding seat 10. The guide rod 12 is set parallel to the screw 11 and plays a guiding role in the movement of the sliding seat 10.

[0037] The outer surface of the pressure roller 201 is covered with an elastic material layer, which can be a rubber layer or a silicone layer, to increase the friction between the pressure roller 201 and the film material, while avoiding scratching the surface of the film material.

[0038] It is understood that the pressing component 2 of this utility model can rotate to adapt to the unevenness of the backlight module surface, height differences, and backlight components of different heights. At the same time, the spring 9 restricts the pressing component 2 from swinging freely, and can apply continuous pressure to the film material through the pressing component 2 to ensure that the pressure roller adheres to the film material and the backlight component with constant pressure, thereby avoiding wrinkles in the film material or damage to the backlight component caused by rigid extrusion.

[0039] A specific application of the operation process in this embodiment is as follows: The horizontal plate 1 is used to connect with the processing table, and the backlight module is fixed on the top surface of the processing table (fixed by a clamp or negative pressure adsorption device). The film material is guided over the backlight module. The motor 13 is started to drive the screw 11 to rotate. The sliding seat 10 drives the translation seat 6 to translate, and then drives the pressing assembly 2 to translate. The pressure roller 201 contacts the film material. After moving to the position above the backlight assembly, the pressure roller 201 adaptively rotates around the hinge point to adjust its position according to the height of the backlight assembly, and then presses the film material onto the surface of the backlight assembly.

[0040] If the backlight module has uneven surface or height difference, the pressure roller 201 will adaptively rotate around the hinge point to adjust the angle and always fit the outline of the backlight module. The film material will be stably pressed onto the backlight module to complete the film coating work.
