Description

Technical Field

[0001] This utility model belongs to the field of flexible circuit board welding technology, and relates to a flexible circuit board that is easy to align and weld. Background Technology

[0002] Flexible circuit boards are printed circuit boards with high reliability and excellent flexibility. They can be bent, rolled, and folded freely, arranged arbitrarily according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] However, while the excellent flexibility of flexible circuit boards provides convenience in many applications, it also presents a significant challenge when soldering two sets of flexible circuit boards. During the soldering process, flexible circuit boards are prone to misalignment due to slight external forces or improper operation. This misalignment not only increases the difficulty of soldering but may also lead to a decrease in soldering quality or even soldering defects such as cold solder joints and short circuits. This significantly hinders the smooth progress of the soldering work and affects the production efficiency and reliability of the entire electronic product. Utility Model Content

[0004] The technical problem this invention aims to solve is that while the excellent flexibility of flexible circuit boards provides convenience in many application scenarios, it also presents a significant challenge when welding two sets of flexible circuit boards. During the welding process, the flexible circuit boards are prone to misalignment due to slight external forces or improper operation. This misalignment not only increases the difficulty of welding but may also lead to a decrease in welding quality or even welding defects such as cold solder joints and short circuits. Consequently, it significantly hinders the smooth progress of the welding work and affects the production efficiency and reliability of the entire electronic product.

[0005] The present invention discloses a flexible circuit board for easy alignment and welding, comprising a substrate, two sets of support plates fixedly connected to the top two sides of the substrate, a rectangular plate movably connected to the top of each support plate, a flexible circuit board body fixedly connected to the top surface of the rectangular plate, an L-shaped plate fixedly connected to the side of the flexible circuit board body away from the rectangular plate, an alignment component and a dust removal component provided in the middle of the substrate.

[0006] The alignment assembly includes a servo motor, two sets of support blocks, two sets of rectangular slots, and a fixing plate. The servo motor is mounted on the middle of one side of the top surface of the substrate. The two rectangular slots are opened on one side of the middle of the substrate. The two support blocks are fixed to one side of the top surface of the substrate. The fixing plate is fixed to the middle of the top surface of the substrate, and the fixing plate has two hollow sections in the middle. The two support blocks are rotatably connected to a driven shaft in the middle. A first pulley set is installed at the end of the driven shaft near the servo motor, and the other end of the first pulley set is installed at the output end of the servo motor.

[0007] The alignment assembly also includes two sets of transmission gears, two sets of large rack plates, and two sets of vertical shafts. The two transmission gears are fixedly connected to the middle of the driven shaft. The two large rack plates are slidably connected to the middle of the two sets of rectangular slots. The two transmission gears and the large rack plates are meshed. A movable plate is fixedly connected to one end of each of the two large rack plates. Two sets of small rack plates are fixedly connected to the middle of the movable plate. The two vertical shafts are rotatably connected to the hollow part in the middle of the fixed plate. A driven gear is fixedly connected to the middle of each of the two vertical shafts.

[0008] The alignment assembly also includes two sets of worm gears and four sets of connecting plates. The two worm gears are respectively fixed to the middle of the two sets of vertical shafts, and the four connecting plates are respectively fixed to the side of the fixed plate away from the movable plate. A horizontal shaft is rotatably connected to the middle of the connecting plate, and a worm wheel is fixed to the middle of the horizontal shaft, and the worm wheel and the worm gear mesh with each other.

[0009] The dust removal assembly includes an arc-shaped block, which is fixed to one side of the top surface of the substrate. A wall tube is fixed to the top of the arc-shaped block, and a support frame is fixed to the middle of the wall tube. A rotating shaft is rotatably connected to the middle of the support frame.

[0010] The dust removal assembly also includes multiple sets of fan blades and a second pulley assembly. The multiple fan blades are fixed to the middle of the rotating shaft. One end of the second pulley assembly is installed on the end of the rotating shaft near the servo motor, and the other end of the second pulley assembly is installed on the output end of the servo motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the alignment component, it is easier to perform welding work on the flexible circuit board body, thereby reducing the tendency of the flexible circuit board body to be misaligned due to its relatively soft properties during welding, which can easily lead to slight external force or improper operation, thus increasing the difficulty of welding work, resulting in a decrease in welding quality and affecting the production efficiency and reliability of the product.

[0012] By installing the dust removal component, it is easy to remove dust from the side of the flexible circuit board that needs to be soldered, thereby reducing the impact of dust on the fluidity of the solder, which can lead to incomplete solder joints, rough surfaces, and reduced overall aesthetics.

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.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: As Figures 1 to 8 As shown, a flexible circuit board that facilitates alignment and soldering includes a substrate 1. Two sets of support plates 11 are fixedly connected to both sides of the top of the substrate 1. A rectangular plate 12 is movably connected to the top of each support plate 11. A flexible circuit board body 13 is fixedly connected to the top surface of the rectangular plate 12. An L-shaped plate 14 is fixedly connected to the side of the flexible circuit board body 13 away from the rectangular plate 12. An alignment component and a dust removal component are provided in the middle of the substrate 1.

[0028] The alignment assembly includes a servo motor 2, two sets of support blocks 21, two sets of rectangular slots 22, and a fixing plate 23. The servo motor 2 is installed in the middle of one side of the top surface of the substrate 1. The two rectangular slots 22 are opened in the middle of one side of the substrate 1. The two support blocks 21 are fixed to one side of the top surface of the substrate 1. The fixing plate 23 is fixed to the middle of the top surface of the substrate 1, and the fixing plate 23 has two hollow parts in the middle. The two support blocks 21 are rotatably connected to the middle of the two support blocks 21. The end of the driven shaft 24 near the servo motor 2 is equipped with a first pulley set 25, and the other end of the first pulley set 25 is installed at the output end of the servo motor 2.

[0029] The alignment assembly also includes two sets of transmission gears 3, two sets of large rack plates 31, and two sets of vertical shafts 34. The two transmission gears 3 are fixedly connected to the middle of the driven shaft 24. The two large rack plates 31 are slidably connected to the middle of the two sets of rectangular slots 22. The two transmission gears 3 and the large rack plates 31 mesh with each other. A movable plate 32 is fixedly connected to one end of the two large rack plates 31. Two sets of small rack plates 33 are fixedly connected to the middle of the movable plate 32. The two vertical shafts 34 are rotatably connected to the hollow part in the middle of the fixed plate 23. A driven gear 35 is fixedly connected to the middle of each of the two vertical shafts 34.

[0030] The alignment assembly also includes two sets of worm gears 4 and four sets of connecting plates 41. The two worm gears 4 are respectively fixed to the middle of the two sets of vertical shafts 34, and the four connecting plates 41 are respectively fixed to the side of the fixed plate 23 away from the movable plate 32. The middle of the connecting plate 41 is rotatably connected to the horizontal shaft 42, and the middle of the horizontal shaft 42 is fixed to the worm wheel 43, and the worm wheel 43 and the worm gear 4 mesh with each other.

[0031] During operation, when welding two sets of flexible circuit board bodies 13 is required, their bottoms can be placed on the support plate 11, the fixing plate 23, and the flexible circuit board body 13. The rectangular plate 12 on one side of the bottom of the two sets of flexible circuit board bodies 13 is attached to the support plate 11, and the L-shaped plate 14 on the other side of the bottom of the two sets of flexible circuit board bodies 13 is respectively stuck on the fixing plate 23 and the movable plate 32. This initially fixes the side of the flexible circuit board body 13 that needs to be welded on the fixing plate 23. Then, the servo motor 2 is driven to work. With the help of the first pulley group 25, the torque of the servo motor 2 can be transmitted to the driven shaft 24, thereby driving the driven shaft 24 to rotate in the middle of the support block 21. When the driven shaft 24 rotates, it will drive the transmission gear 3 to rotate. Under the rotation of the transmission gear 3, the large rack plate 31 can be pushed to slide in the middle of the rectangular groove 22 toward the fixing plate 23, thereby driving the movable plate 32 to move closer to the fixing plate 23.

[0032] Simultaneously, when the movable plate 32 moves, it will drive the other set of flexible circuit board bodies 13 on its top to move. When the movable plate 32 moves to the point where it is about to fit against the fixed plate 23, the small rack plate 33 will contact and mesh with the driven gear 35, thereby driving the driven gear 35 to rotate. Under the rotation of the driven gear 35, the vertical shaft 34 and the worm 4 can be driven to rotate. When the worm 4 rotates, it will drive the worm wheel 43 to rotate, which in turn drives the horizontal shaft 42 to rotate at the connecting plate 41. The operation of the servo motor 2 can be stopped when the movable plate 32 fits against the fixed plate 23. In this way, the corresponding sides of the two sets of flexible circuit board bodies 13 that need to be welded can be fitted together. And through the cooperation of the worm 4 and the worm wheel 43, a certain self-locking effect can be achieved, thereby strengthening the stability between the two sets of flexible circuit board bodies 13.

[0033] After the two sets of flexible circuit board bodies 13 are aligned, they can be welded using welding tools. After the two sets of flexible circuit board bodies 13 are welded, the flexible circuit board bodies 13 can be lifted up and removed to separate them from the movable plate 32 and the fixed plate 23. Then, the servo motor 2 is driven to reverse and move the movable plate 32 away from the fixed plate 23 before the servo motor 2 stops working.

[0034] This step, through the setting of the alignment components, facilitates the welding work on the flexible circuit board body 13, thereby reducing the likelihood that the flexible circuit board body 13 will easily deviate due to its relatively soft properties during welding, even with slight external forces or improper operation. This would increase the difficulty of the welding work, leading to a decrease in welding quality and affecting the production efficiency and reliability of the product.

[0035] Example 2: As Figure 1 , Figure 2 , Figure 4 and Figure 8As shown, the dust removal assembly includes an arc-shaped block 5, which is fixed to one side of the top surface of the substrate 1. A wall tube 51 is fixed to the top of the arc-shaped block 5, and a support frame 52 is fixed to the middle of the wall tube 51. A rotating shaft 53 is rotatably connected to the middle of the support frame 52.

[0036] The dust removal assembly also includes multiple sets of fan blades 6 and a second pulley set 61. The multiple fan blades 6 are fixed to the middle of the rotating shaft 53. One end of the second pulley set 61 is installed on the end of the rotating shaft 53 near the servo motor 2, and the other end of the second pulley set 61 is installed on the output end of the servo motor 2.

[0037] When the servo motor 2 is running, its torque can be transmitted to the rotating shaft 53 through the second pulley set 61. This causes the rotating shaft 53 to drive the fan blade 6 to rotate in the middle of the support frame 52. The rotation of the rotating shaft 53 and the fan blade 6 can generate a certain amount of wind force, which can blow the fixed plate 23. When the movable plate 32 moves to the fixed plate 23 and the servo motor 2 stops running, the rotating shaft 53 will stop working.

[0038] This step, through the installation of the dust removal component, facilitates the dust removal work on the side of the flexible circuit board body 13 that needs to be soldered, thereby reducing the impact of dust on the fluidity of the solder, which can lead to incomplete solder joints, rough surfaces, and reduced overall aesthetics.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
