Description

Technical Field

[0001] This utility model relates to the field of optical communication equipment manufacturing technology, and in particular to welding fixtures for XGS-PON devices. Background Technology

[0002] In the field of optical communication equipment manufacturing, the welding process between the receiver flexible board and the transmitter flexible board and the PCB board in the assembly process of XGS-PON devices is a critical step that determines production efficiency and product quality. The fixtures used in traditional welding processes have many technical defects, severely restricting production efficiency and product yield. The welding fixtures commonly used in existing technologies mainly suffer from the following technical problems:

[0003] At the structural design level, traditional fixture positioning systems have significant flaws. Most fixtures employ a single-plane positioning method, using only simple slots for two-dimensional positioning of the PCB board, lacking multi-point positioning capabilities in three-dimensional space. This design makes the PCB board prone to micro-displacement during soldering, especially for multi-layer PCBs with sensitive components, where the alignment accuracy between the gold finger area and the flange of optical components is difficult to guarantee. More seriously, the support structure of existing fixtures often conflicts with the component layout on the PCB board, failing to provide effective clearance for surface-mount components, leading to component damage due to pressure during soldering.

[0004] Meanwhile, traditional fixtures have significant design flaws in terms of ease of operation. Due to the lack of a reasonable spatial layout within the fixture body, operators need to frequently adjust the fixture angle to accommodate different welding positions during welding. Especially when welding flexible receiving plates, the weld point is often obscured by the fixture body structure, forcing operators to adopt unnatural postures for welding operations. This not only reduces welding efficiency but also easily leads to operator fatigue. More importantly, the fixing mechanism of existing fixtures mostly uses bolt fastening, requiring the simultaneous operation of multiple fasteners to complete the device fixation. This design results in a single clamping time of 3-5 minutes, seriously affecting overall production efficiency.

[0005] Therefore, we propose XGS-PON device soldering fixtures. Utility Model Content

[0053] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0054] like Figures 1-4 As shown, this embodiment discloses an XGS-PON device soldering fixture, which is used for soldering the receiver flexible plate 2 and transmitter flexible plate 3 on the PCB board 4 to the device 1, simplifying the operation steps and improving soldering efficiency. This manual soldering fixture includes: device 1, receiver flexible plate 2, transmitter flexible plate 3, PCB board 4, base 5, latch 6, semi-threaded screw 7, and cover plate 8. For positioning the PCB board 4, a cylindrical boss is designed on the fixture to position it at the semi-circular opening on the side of the PCB board 4. The gold fingers of the PCB board 4 are positioned by corresponding limiting grooves on both sides. After the PCB board 4 is fully positioned, the device 1 is placed into the corresponding flange limiting groove A. After the PCB board 4 and the device 1 are fully positioned, the cover plate 8 and latch 6 are flipped to provide downward pressure to further fix the PCB board 4 and the device 1. Then, the entire fixture is flipped so that the receiver pad is facing the face to begin soldering.

[0055] Among them, the base 5 is used to fix the PCB board 4 and the device 1 by setting a positioning structure;

[0056] The cover plate 8 is rotatably mounted on the base 5 and is used to simultaneously cover and fix the PCB board 4 and the device 1;

[0057] The latch 6 rotates horizontally on the base 5 and is used to lock the cover plate 8;

[0058] The base 5 is also equipped with a support structure E to support the PCB board 4 and keep it horizontal and stable.

[0059] The innovations of this utility model are: 1. By designing a 90° rotating support structure E, the placement and welding direction of the PCB and optical device 1 can always face the human face, simplifying the entire welding process; 2. Multiple cutting lines to increase friction are set on the entire fixture, improving the convenience for the operator to handle.

[0060] Specifically, the components of the manual soldering fixture include: PCB board 4, receiving flexible plate 2, base 5, cover plate 8, latch 6, and semi-threaded screw 7. The base 5 has limiting grooves for both PCB board 4 and device 1. The PCB board 4 is positioned by a cylindrical boss in conjunction with the semi-circular opening on the side wall and the limiting groove for the gold fingers. Since many sensitive components are arranged on the PCB board 4, the base 5 provides sufficient clearance for these components. For device 1, a limiting groove A is provided on the base 5 for the flange of device 1. Simply insert the flange of device 1 to complete the positioning. After both are positioned, the cover plate 8 is flipped to press down on both device 1 and PCB board 4, and the latch 6 is used to secure the cover plate 8, thus fixing device 1 and PCB board 4. Then, the entire fixture is flipped so that the solder pads of the receiving end of device 1 face the user's face, and the receiving flexible plate 2 is manually inserted into the solder joints of the receiving end solder pads and soldered.

[0061] like Figure 3 As shown, the base 5 in this embodiment includes:

[0062] Flange limiting groove A, which is used to fix component 1;

[0063] The cover plate limiting structure B is used to limit the transition of the cover plate 8 and to better position the cover plate 8; the first positioning structure C and the second positioning structure F are used to position the PCB and improve the welding accuracy; the support structure E is used to support the hollowed-out part of the PCB board 4, making the whole more horizontal and improving the welding effect.

[0064] The PCB board limiting structure G has the same shape as the PCB board 4, which facilitates the embedding and positioning of the PCB board 4.

[0065] like Figure 4 As shown, the cover plate 8 in this embodiment is flipped and mounted on the base 5. Its structure includes: a device pressure plate 11 and a PCB board pressure plate 12, which are located at the upper ends of the device 1 and the PCB board 4, respectively, and are used to position them.

[0066] The contact rod 9 and the gripper 10 are located on the device pressure plate 11. The gripper 10 has a slot that can hold the side wall of the flexible plate to prevent the flexible plate from loosening. After the cover plate 8 is flipped into place, the contact rod 9 can position the welding point of the flexible plate with the welding point of the device 1 to improve the subsequent welding effect.

[0067] The specific working principle in this embodiment is as follows: The welding of the transmitting flexible plate 3 has been completed during the welding process of this fixture, so only the receiving flexible plate 2 needs to be welded. The operation process is as follows: First, the PCB board 4 is placed in the base 5 for positioning. The limiting structure G of the base 5 is used to limit the gold fingers of the PCB board 4. The two semi-circular grooves on the side wall of the PCB board 4 are respectively limited by the first positioning structure C and the second positioning structure F. The cylindrical boss at the first positioning structure C can also provide a certain support for the PCB board 4. At the same time, the tail of the PCB board 4 without components is supported by the support structure E to maintain balance. After the PCB board 4 is completely positioned, the flange of the device 1 is vertically placed into the corresponding limiting groove A to complete the positioning. After component 1 and PCB board 4 are positioned, the cover plate 8 is flipped so that the PCB board pressure plate 12 presses down on the gold fingers of PCB board 4, while the component pressure plate 11 presses down on component 1. Then, the cover plate 8 is secured with the latch 6. Multiple keyways are provided on the cover plate 8 to increase friction and facilitate flipping the cover plate. Subsequently, the entire fixture is flipped so that the column D of the base 5 supports the entire fixture. At the same time, the receiving end pad is facing the face, and the receiving end flexible plate 2 is manually placed onto the receiving end pad before welding begins. This process is repeated. Because the fixture is made of mold steel, which is heavier than aluminum alloy, it will not easily wobble after flipping the entire fixture, improving overall stability. In addition, the multiple keyways on the entire fixture make it easier to handle.

[0068] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
