Description

Technical Field

[0001] This utility model relates to the field of flat panel backlight assembly, and in particular to an FPC blowing mechanism. Background Technology

[0002] As the quality requirements for smart tablets become increasingly stringent, such as ultra-thinness and high brightness, the manufacturing process also becomes more demanding. A tablet backlight consists of several components: reflectors, upper reflectors, lower reflectors, a light guide plate, LED strips, diffusers, adhesive strips, and light-shielding adhesive. After the LED strips and light guide plate are assembled, the LED strip FPC needs to extend beyond the backlight by passing through the barbed FPC holes in the adhesive strip, facilitating assembly and soldering for the customer.

[0003] Currently, traditional air blowing mechanisms are combinations of aluminum alloy and rubber air tubes, and are single air tubes. When the FPC passes through the gold finger barbs, the application of these air blowing mechanisms still has shortcomings: Because the air blowing mechanism uses a split combination (aluminum alloy and rubber tube), the structure is not rigid enough and is prone to shaking and swaying under air pressure, which makes it impossible to accurately guide the FPC to the FPC hole of the plastic iron. The single-pipe air outlet design leads to excessively concentrated airflow, resulting in excessive local force on the FPC. This can easily cause the FPC to bend, fold, or get stuck at the orifice, preventing it from passing through smoothly.

[0004] Therefore, it is necessary to provide a new FPC blowing mechanism to solve the above-mentioned technical problems. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 7 The present invention provides an FPC blowing mechanism, which includes an air supply component 1 and an adjustable mounting component 2.

[0020] For gas supply component 1; Please see Figure 2 and Figure 3 The gas supply assembly 1 includes a gas supply base 11, which has a cavity 12 inside. The upper end of the gas supply base 11 is provided with an air inlet pipe 13, and the lower end is detachably connected with at least three air outlet pipes 14. The cavity 12 inside the gas supply base 11 is configured as a low area 15 corresponding to the position of the air inlet pipe 13 and a high area 16 corresponding to the position of the air outlet pipe 14. The area of ​​the low area 15 forms a water storage tank, and the lower end of the gas supply base 11 is provided with a drain outlet 17 that communicates with the water storage tank. The drain outlet 17 is closed by an interference fit plug 18. The air outlet pipe 14 is an integral aluminum alloy pipe, and the connection between it and the air supply base 11 includes threaded connection and magnetic connection.

[0021] It should be noted that in the air supply assembly 1, the air supply base 11 is the main structure, which is set as a shell structure with an internal cavity 12. The upper end of the air supply base 11 has an air inlet pipe 13, and the lower end has an air outlet pipe 14. In use, the air inlet pipe 13 is used to connect to an external air supply device or pipeline to introduce the gas into the cavity 12, and then out through the air outlet pipe 14, so that it can directly act on the FPC to assist in the installation and positioning of the FPC. The exhaust pipe 14 is an integrally formed aluminum alloy pipe to enhance its structural rigidity. When exhausting gas, the pipe itself has higher stability and will not shake, ensuring that the airflow direction is always accurately aligned with the FPC hole on the plastic iron. At the same time, there are at least three exhaust pipes 14 to improve the installation accuracy of the FPC and make the airflow more dispersed, so as to form a uniform and stable air curtain, thereby better pushing the FPC through the hole and avoiding damage to it. The cavity 12 has a low zone 15 corresponding to the air inlet pipe 13 and a high zone 16 corresponding to the air outlet pipe 14. The introduced gas first enters the low zone 15, and then passes through the high zone 16 before being discharged from the air outlet pipe 14. This design makes the low zone 15 area form a water storage structure to concentrate the condensate formed during the gas supply process, preventing water vapor from being blown onto the FPC or precision parts, and also extending the service life of the mechanism. A drain outlet 17 is also provided at the lower end of the air supply seat 11 to periodically drain the water accumulated inside the water storage structure.

[0022] For the adjustable mounting assembly 2, it includes a stand 21, a vertical adjustment component 22, a horizontal adjustment component 23, a rotation adjustment component 24 and a mounting plate 25, with one end of the air supply seat 11 bolted to the mounting plate 25; Please see Figure 5 The vertical adjustment component 22 includes a first mounting base 221, which is bolted to the bracket 21. A vertical groove 222 penetrating the top surface is provided on one side of the first mounting base 221, and a top plate 223 is bolted to the top. A first single helical screw 226 extending into the vertical groove 222 is rotatably connected to the top plate 223. A first knob 227 is fixed to one end of the first single helical screw 226. A first slide block 224 is provided inside the vertical slide groove 222. A first transmission seat 225 is integrally connected to one side of the first slide block 224. A first single helical screw 226 passes through the first transmission seat 225 and is threadedly connected to it to drive the first slide block 224 to move in the horizontal direction.

[0023] It should be noted that in the adjustable mounting assembly 2, the stand 21 is the mounting base. The stand 21 is fixed to the machine body by bolts to provide a stable support base. For the vertical adjustment component 22, its first mounting base 221 is fixed on the bracket 21. It has a vertical slide groove 222 on one side, and a movable first slide block 224 is provided inside the vertical slide groove 222. A first transmission seat 225 is provided on one side of the first slide block 224. A first single helical screw 226 is also provided on the top plate 223. The first single helical screw 226 passes through the first transmission seat 225 and is threadedly connected to it. At the same time, a first knob 227 is provided at one end of the first single helical screw 226. The first single helical screw 226 can be driven to rotate through the first knob 227, thereby driving it to move vertically and adjusting the first slide block 224. This enables the vertical position adjustment of the air supply seat 11. The first mounting base 221 and the top plate 223 together form a basic frame structure. This split design makes it easier to disassemble and assemble the first slide 224, which facilitates the subsequent inspection and replacement of each structure.

[0024] Please see Figure 6The lateral adjustment component 23 includes a second mounting base 231, which is bolted to one side of the first slide block 224. A transverse slide groove 232 penetrating the side is provided on one side of the second mounting base 231, and a first side plate 233 is bolted to the side. A second single helical screw 236 extending into the transverse slide groove 232 is rotatably connected to the first side plate 233. A second knob 237 is fixed to one end of the second single helical screw 236. A second slide block 234 is provided inside the transverse slide groove 232. A second transmission seat 235 is integrally connected to one side of the second slide block 234. A second single helical screw 236 passes through the second transmission seat 235 and is threadedly connected to it to drive the second slide block 234 to move in the vertical direction.

[0025] It should be noted that the structure and adjustment process of the horizontal adjustment component 23 are basically the same as those of the vertical adjustment component 22, so as to realize the horizontal position adjustment of the air supply seat 11. However, they will not be described in detail here.

[0026] Please see Figure 7 The rotating adjustment component 24 includes a housing 241, which is bolted to one side of the second slide block 234. One side of the housing 241 has an opening, and a second side plate 242 is bolted to the opening. A vertically arranged first rotating shaft 243 and a horizontally arranged second rotating shaft 246 are rotatably connected inside the outer casing 241. A worm gear 244 located inside the outer casing 241 is fixed on the first rotating shaft 243, and one end of the first rotating shaft 243 extends to the outside of the outer casing 241 and is fixed with a third knob 245. A worm wheel 247 located inside the outer casing 241 is fixed on the second rotating shaft 246, and the worm wheel 247 meshes with the worm gear 244 for transmission. One end of the second shaft 246 also passes through the second side plate 242, and the mounting plate 25 is fixed to that end of the second shaft 246.

[0027] It should be noted that: for the rotation adjustment component 24, its outer shell 241 is fixed on the second slide 234. The outer shell 241 has a vertically arranged first rotating shaft 243 and a horizontally arranged second rotating shaft 246. The first rotating shaft 243 is an active drive structure, and one end of it has a third knob 245. The third knob 245 can drive the first rotating shaft 243 to rotate, thereby driving the worm gear 244 to rotate. The second rotating shaft 246 has a worm wheel 247 that meshes with the worm gear 244, so as to drive the second rotating shaft 246 to rotate through this transmission structure. The mounting plate 25 is fixed to one end of the second rotating shaft 246 to realize the rotation adjustment of the air supply seat 11 in the horizontal direction. The worm gear 247 and worm 244 have a self-locking function, thus enabling the rotation adjustment of the mounting plate 25 and also serving a positioning function.

[0028] Please see Figure 5 and Figure 6 Positioning elements 26 are provided between the first mounting base 221 and the vertical slide groove 222, and between the second mounting base 231 and the horizontal slide groove 232; Positioning component 26 consists of a positioning slide rail and a positioning slide groove.

[0029] It should be noted that the positioning component 26 is a slide rail and slide groove structure. The setting of the positioning component 26 can improve the compactness of the connection between components and make the movement of components more stable.

[0030] The specific operating procedure of the device is as follows: First, adjust the air outlet pipe 14 according to the FPC itself, that is, adjust the vertical and horizontal positions of the air outlet pipe 14 and the horizontal tilt angle. For example, when vertical position adjustment is required, a vertical adjustment component 22 is used. The vertical adjustment component 22 has a first mounting base 221 fixed to the bracket 21, and a vertical groove 222 on one side. A movable first slide block 224 is provided inside the vertical groove 222, and a first transmission seat 225 is provided on one side of the first slide block 224. A first single-helix screw 226 is also provided on the top plate 223. The first single-helix screw 226 passes through the first transmission seat 225 and is threadedly connected to it. A first knob 227 is located at one end of the first single-helix screw 226. The first knob 227 can drive the first single-helix screw 226 to rotate, thereby driving its vertical movement and adjusting the first slide block 224. This allows for vertical position adjustment of the air supply seat 11 (the adjustment principle of the horizontal adjustment component 23 is the same). When horizontal angle adjustment is required, a rotation adjustment component 24 is used. The outer shell 241 of the rotation adjustment component 24 is fixed on the second slide block 234. The outer shell 241 has a vertically arranged first rotating shaft 243 and a horizontally arranged second rotating shaft 246. The first rotating shaft 243 is an active drive structure, and one end of it has a third knob 245. The third knob 245 can drive the first rotating shaft 243 to rotate, thereby driving the worm gear 244 to rotate. The second rotating shaft 246 has a worm wheel 247 that meshes with the worm gear 244, so as to drive the second rotating shaft 246 to rotate through this transmission structure. The mounting plate 25 is fixed to one end of the second rotating shaft 246 to realize the rotation adjustment of the air supply seat 11 in the horizontal direction. After the adjustment is completed, gas can be introduced through the gas supply component 1 to assist in the installation and positioning of the FPC. That is, a gas supply device or gas supply pipe is connected to the gas supply pipe 13 to introduce the gas into the cavity 12 and finally out from the gas outlet pipe 14, thereby acting on the FPC. After prolonged use, water will accumulate in the low area 15 inside the cavity 12. The water can be drained by opening the plug 18.

[0031] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
