Description

Technical Field

[0001] This utility model relates to the field of flexible plate welding technology, and in particular to PON-MAC flexible plate welding fixture. Background Technology

[0002] In the field of flexible circuit board (PCB) soldering, significant technical challenges and limitations exist, primarily stemming from the lack of specially designed PCB soldering fixtures. This makes it difficult to guarantee positioning accuracy and stability during the soldering process. Traditional soldering methods typically rely on simple auxiliary tools, such as rectangular iron blocks without any positioning function combined with tape, to fix and support the PCB and flexible circuit board. However, these tools have revealed many shortcomings in practical applications, severely impacting soldering efficiency and product quality.

[0003] Existing soldering tools lack precise positioning capabilities, making it difficult to effectively align solder joints on PCBs and flexible circuit boards. This forces operators to rely on experience and visual judgment to adjust positions during manual soldering, which can easily lead to misalignment or displacement. Especially in large-scale production or high-precision scenarios, this method struggles to meet quality control requirements, resulting in a high soldering failure rate and increased production costs and time.

[0004] Traditional tools have significant limitations in supporting and securing PCBs and flexible circuit boards. Due to the lack of specialized positioning posts, grooves, and support structures, PCBs are prone to floating or tilting during soldering, especially when manual downward pressure is applied. The slender extensions of the PCB are easily bent or deformed, further affecting soldering accuracy. Furthermore, the lightweight nature of flexible circuit boards makes them susceptible to airflow or unstable operation, leading to positional shifts and increasing uncertainty in the soldering process.

[0005] Furthermore, the design of existing tools fails to adequately protect the components and gold fingers on the PCB board. During soldering, these critical components may be damaged due to improper support or fixation, especially at high temperatures, where the gold fingers are particularly vulnerable, affecting product reliability and lifespan. Additionally, traditional tools often lack design features to avoid the edges and corners of the PCB board, posing a risk of component abrasion or damage due to improper handling.

[0006] In summary, existing flexible PCB soldering technologies and tools suffer from the following main problems: insufficient positioning accuracy, leading to a high risk of soldering misalignment; poor support and fixation, affecting soldering stability; lack of protection for critical PCB components, posing a risk of damage; and inconvenient operation and low efficiency. These problems severely restrict the quality and efficiency of flexible PCB soldering, necessitating a specially designed flexible PCB soldering fixture that can provide precise positioning, stable support, and efficient operation to address the many shortcomings of existing technologies.

[0007] Therefore, we propose the PON-MAC flexible board welding fixture. Utility Model Content

[0016] The positioning post on the base is a circular post, which is used to mate with the openings on the PCB board to ensure the correct positioning of the PCB board.

[0017] The groove on the base is a rectangular groove, used to accommodate the gold finger part on the PCB board and provide support.

[0018] The base is also provided with a boss for supporting the slender extension of the PCB board.

[0019] Both the PCB cover and the latch are connected to the base by semi-threaded screws. The PCB cover can rotate around the semi-threaded screws, which facilitates disassembly and installation.

[0020] The cover plate is connected to the base by a cylindrical pin. The cover plate can rotate around the cylindrical pin, which is fixed by epoxy resin to ensure the smooth rotation of the cover plate and prevent the cylindrical pin from coming out.

[0021] The cover plate is equipped with knurled small-head screws and hook springs. The cover plate can automatically lock the position of the flexible plate by means of the elastic force of the hook springs, without the need for additional operation of the locking buckle.

[0022] The base has multiple grooves at the bottom to facilitate the placement and removal of the clamp, and the edges of the base are rounded and chamfered to ensure safe use.

[0023] The PCB cover plate and the cover plate are provided with multiple threaded holes to facilitate force adjustment and operation.

[0041] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0042] like Figures 1-5 As shown, this embodiment discloses a PON-MAC flexible board welding fixture, including a base 1, a PCB cover plate 11, a latch 2, a cover plate 8, a first flexible board 6, a second flexible board 7, a semi-threaded screw 10, a knurled small-head screw 4, a hook spring 3, and a cylindrical pin 5. The purpose of this invention is to provide a fixture suitable for manual welding. Positioning is achieved by selecting the opening of the PCB board 9 and the sides of the gold fingers, while simultaneously reserving a rectangular groove for slight movement of the flexible board. The flexible board is placed in the groove for manual welding. This embodiment ensures accuracy and stability during the welding process through precise positioning design and the fine-tuning function of the flexible board, while also considering the convenience and efficiency of manual operation, reducing welding errors caused by human error.

[0043] Specifically, in this embodiment, the base 1 is used to support and position the PCB board 9. The base 1 is provided with multiple positioning posts, grooves, and flexible board placement grooves, which are used to position the PCB board 9 and the flexible board, respectively. The design of the base 1 fully considers the structural characteristics of the PCB board 9. Through the cooperation of multiple positioning posts and grooves, it ensures that the PCB board 9 will not shift or tilt during the positioning process. At the same time, the design of the flexible board placement groove provides a stable placement platform for the flexible board, reducing the displacement of the flexible board during the soldering process.

[0044] The PCB cover plate 11 is connected to the base 1 via a semi-threaded screw 10. The PCB cover plate 11 can rotate around the semi-threaded screw 10 to cover and fix the PCB board 9. The rotating design of the PCB cover plate 11 not only facilitates operation but also allows adjustment of the cover plate's tightening force, ensuring the stability of the PCB board 9 during soldering. The use of the semi-threaded screw 10 makes the installation and removal of the cover plate more convenient, reducing the impact on production efficiency.

[0045] The latch 2 is also connected to the base 1 via a semi-threaded screw 10. The latch 2 can rotate around the semi-threaded screw 10 to lock the position of the PCB cover 11. The design of the latch 2 further enhances the fixing effect of the PCB cover 11. By rotating the latch 2, the PCB cover 11 can be precisely locked in position to ensure that the PCB board 9 will not move during the soldering process.

[0046] The cover plate 8 is connected to the base 1 via a cylindrical pin 5. The cover plate 8 can rotate around the cylindrical pin 5 to cover and fix the flexible plate. The rotating design of the cover plate 8 makes the fixing of the flexible plate more flexible, and the use of the cylindrical pin 5 ensures the smoothness of the rotation of the cover plate 8. At the same time, the stability of the cover plate 8 is guaranteed by the fixing of the cylindrical pin 5.

[0047] Flexible board 6 and flexible board 7 are placed in the grooves D and E of flexible board 1 at the tail of base 1. The position of the flexible boards can be fine-tuned to align with the solder joints of PCB board 9. The design of the flexible board placement grooves allows the flexible boards to be easily placed and adjusted on base 1, while the sufficient distance allows the operator to easily make fine adjustments to ensure the accurate positioning of the flexible boards. In addition, a support point C is provided on one side of the grooves D and E of flexible board 1 to support the solder joints.

[0048] In another embodiment, the positioning post on the base 1 is a circular post B, which is used to mate with the opening of the PCB board 9 to ensure the correct positioning of the PCB board 9. The circular post B is designed with a self-locking function, which can precisely mate with the opening of the PCB board 9 to ensure that the PCB board 9 will not shift during the positioning process. At the same time, the surface treatment of the circular post B makes the positioning more stable and reliable.

[0049] In another embodiment, the groove on the base 1 is a rectangular groove used to accommodate the gold finger portion on the PCB board 9 and provide support. The rectangular groove design not only accommodates the gold finger but also supports it through the edge of the groove, preventing the gold finger from bending or deforming during the soldering process.

[0050] In this embodiment, the base 1 is also provided with a boss for supporting the slender extension of the PCB board 9. The boss design can precisely support the slender extension of the PCB board 9, preventing the PCB board 9 from bending or deforming due to artificial downward pressure during the soldering process. At the same time, the height and position of the boss can be adjusted according to the specific structure of the PCB board 9.

[0051] Both the PCB cover plate 11 and the latch 2 are connected to the base 1 via semi-threaded screws 10. The PCB cover plate 11 can rotate around the semi-threaded screws 10, facilitating disassembly and installation. The use of semi-threaded screws 10 makes the installation and disassembly of the PCB cover plate 11 and the latch 2 more convenient, reducing time and labor in the production process. At the same time, the rotating design makes the position adjustment of the cover plate and the latch more flexible.

[0052] In this embodiment, the cover plate 8 is connected to the base 1 via a cylindrical pin 5. The cover plate 8 can rotate around the cylindrical pin 5, which is fixed with epoxy resin to ensure smooth rotation of the cover plate 8 and prevent the cylindrical pin 5 from coming off. The epoxy resin fixing design of the cylindrical pin 5 ensures the smooth rotation of the cover plate 8 and prevents the cylindrical pin 5 from coming off due to long-term use, thus ensuring the stability and service life of the cover plate 8.

[0053] In this embodiment, the cover plate 8 is equipped with a knurled small-head screw 4 and a hook spring 3. Through the elasticity of the hook spring 3, the cover plate 8 can automatically lock the position of the flexible plate without the need for additional operation of the latch 2. The cooperative design of the knurled small-head screw 4 and the hook spring 3 enables the cover plate 8 to automatically lock the position of the flexible plate, reducing the complexity and time of manual operation. At the same time, the elasticity design of the hook spring 3 ensures the stability and reliability of the locking.

[0054] In another embodiment, the base 1 has multiple pre-drilled grooves F at its bottom to facilitate the handling and placement of the clamp, and the edges of the base 1 are rounded and chamfered to ensure safe use. The groove design at the bottom of the base 1 makes the clamp easier to handle and store, while the rounded and chamfered edges reduce the risk of injury to operators from sharp corners, ensuring safe use.

[0055] In this embodiment, the PCB cover plate 11 and cover plate 8 are provided with multiple threaded holes to facilitate force adjustment and operation. The threaded hole design makes it easier to adjust the force of the PCB cover plate 11 and cover plate 8, and the operator can adjust the tightening force as needed to ensure the stability of the PCB board 9 and the flexible board.

[0056] In this embodiment, the gold finger positioning groove A on the base 1 has a certain space reserved to facilitate the application of cushioning materials such as high-temperature tape to protect the gold finger part. The spatial design of the gold finger positioning groove A allows for the application of cushioning materials such as high-temperature tape, which can protect the gold finger part during the soldering process and prevent damage to the gold finger caused by high temperature or other external factors.

[0057] Two positioning posts are designed on the base 1 to position the PCB board 9 on both sides and support one side of the PCB board 9. The middle of the base 1 provides sufficient space for the densely packed components on the PCB board 9 to ensure that the components are not scratched or bumped. The head of the base 1 has a slot to position the gold fingers and support the other side of the PCB board 9. At the same time, the entire base 1 has reserved space to avoid the corners of the PCB board 9. The design of the base 1 fully considers the structural characteristics of the PCB board 9. Through the cooperation of the positioning posts and the slot, it is ensured that the PCB board 9 will not shift or tilt during the positioning process. At the same time, the space design in the middle and head of the base 1 can avoid damage to the components and corners of the PCB board 9.

[0058] The PCB cover plate 11 on the base 1 uses a semi-threaded screw 10 as a rotating shaft at its pivot point, which facilitates the disassembly of the PCB cover plate 11 later. The use of the semi-threaded screw 10 makes the rotation of the PCB cover plate 11 more flexible and the disassembly process more convenient, reducing the time and labor required in the production process.

[0059] The rear of base 1 has a groove for placing the flexible plate, while leaving sufficient distance for easy manual adjustment of the plate's position. The groove design allows the flexible plate to be easily placed and its position adjusted on base 1, while the sufficient distance allows operators to easily make fine adjustments to ensure the plate's accurate positioning.

[0060] Because the human hand exerts significant downward pressure on the PCB board 9 during soldering, it can cause the PCB board 9 to float up and down. Therefore, the support point C on the base 1 supports the slender extension of the PCB board 9 while ensuring that it does not touch the components on the PCB board 9. The design of the support point C can precisely support the slender extension of the PCB board 9, preventing the PCB board 9 from bending or deforming due to the human downward pressure during the soldering process. At the same time, the height and position of the support point C can be adjusted according to the specific structure of the PCB board 9 to ensure that it does not touch the components on the PCB board 9.

[0061] A through hole is made at the rear of the base 1 to allow the cover plate 8 and the cylindrical pin 5 to rotate together. Since this structure also requires the use of a knurled small-head screw 4 and a hook spring 3, a semi-threaded screw 10 is not used as the rotating shaft. Instead, adhesive is applied to the through hole of the cover plate 8. This ensures both the smooth rotation of the cover plate 8 and prevents the cylindrical pin 5 from easily coming off. The design of the fit between the cover plate 8 and the cylindrical pin 5 makes the rotation of the cover plate 8 smoother, while the adhesive fixing of the cylindrical pin 5 prevents it from coming off due to long-term use, ensuring the stability and service life of the cover plate 8.

[0062] To facilitate the handling and placement of the clamp, multiple pre-drilled grooves F are provided at the bottom of the base 1. Furthermore, considering safety during manual use, the sharp edges and corners of the entire clamp are rounded and chamfered. The groove design at the bottom of the base 1 makes the clamp easier to handle and store, while the rounded and chamfered edges reduce the risk of injury to operators from sharp corners, ensuring safe operation.

[0063] In this embodiment, a portion of the extended portion of the PCB cover plate 11 is fitted with the latch 2 to cover the PCB board 9. The extended design of the PCB cover plate 11 allows the cover plate to engage with the latch 2, further enhancing the fixing effect of the PCB board 9 and ensuring that the PCB board 9 will not move during the soldering process.

[0064] In this embodiment, a semi-threaded screw 10 is used as a rotation axis for the latch 2, facilitating subsequent disassembly. The design of the latch 2 further enhances the fixing effect of the PCB cover plate 11. By rotating the latch 2, the PCB cover plate 11 can be precisely locked in position, ensuring that the PCB board 9 will not move during the soldering process.

[0065] In this embodiment, the cover plate 8 is used in conjunction with the knurled small-head screw 4 and the hook spring 3. Due to the elasticity, manual operation only requires swinging the screw mounted on the cover plate 8, without the need for the locking buckle 2, to cover the first flexible plate 6 or the second flexible plate 7 in one step. The design of the knurled small-head screw 4 and the hook spring 3 allows the cover plate 8 to automatically lock the position of the flexible plate, reducing the complexity and time of manual operation. At the same time, the elasticity design of the hook spring 3 ensures the stability and reliability of the locking.

[0066] The specific working principle is as follows: The base 1 is provided with raised circular pillars B, which are used to match the openings of the PCB board 9 and also for positioning after the entire fixture is installed; the PCB board 9 is first inserted into any of the circular pillars B of the base 1 through the opening, and at the same time the gold finger part is embedded into the corresponding limiting groove A of the base 1. At this time, the slender extension of the PCB board 9 will also be supported by the support C of the base 1. After ensuring that the PCB board 9 is completely positioned, the outer extension G of the PCB cover plate 11 is rotated to fit tightly against the base 1, and then the fastening part of the latch 2 is fastened to the outer extension G of the PCB cover plate 11. After PCB board 9 is in place, flexible board 6 or flexible board 7 is placed in the corresponding flexible board groove. The position of the flexible board is then finely adjusted by human intervention to align it with the solder joints of PCB board 9 for soldering. Due to the light weight of the flexible board, it may shift slightly due to airflow. In this case, the flexible board can be fixed by flipping the cover plate 8 after alignment with the solder joints. There are two ways to flip the cover plate 8: one is to flip the outer extension I of the cover plate 8, and the other is to flip the knurled small-head screw 4 screwed on the cover plate 8. The placement and fixing process of the flexible board includes: first, placing flexible board 6 or flexible board 7 into the flexible board groove of the base 1; then, finely adjusting the position of the flexible board by human intervention to align it with the solder joints of PCB board 9; next, flipping the cover plate 8 to fix the flexible board after alignment with the solder joints. The flipping method of the cover plate 8 can be either flipping the outer extension I of the cover plate 8 or screwing the knurled small-head screw 4 on the cover plate 8 to ensure the stability of the flexible board position.

[0067] After soldering one side of the flexible board of PCB board 9, loosen PCB cover plate 11 and cover plate 8, place the unsoldered side of PCB board 9 into the corresponding groove, and then solder the second flexible board. Repeat this process. The soldering process includes: after completing the soldering of one side of the flexible board of PCB board 9, loosen PCB cover plate 11 and cover plate 8; flip PCB board 9 over, placing the unsoldered side into the corresponding groove; then solder the second flexible board, repeating the above steps until all soldering work is completed.

[0068] After the fixture is welded, use your fingers to lift the pre-reserved groove F at the bottom of base 1 and place it back in its original position. The fixture placement process includes: after completing the welding work, the operator uses their fingers to lift the pre-reserved groove F at the bottom of base 1 and places the fixture in the designated storage location to ensure the safety and convenience of the fixture.
