Description

Technical Field

[0001] This application relates to the field of component fixing, and in particular to a fastener for fixing a water baffle. Background Technology

[0002] In modern electronics manufacturing, electronic products are constantly evolving towards miniaturization and increasing complexity, leading to increasingly stringent quality control requirements for printed circuit boards (PCBs). Ensuring post-soldering cleanliness—that is, efficiently and thoroughly removing flux residues and other contaminants—has become a critical step. With increasing automation, major manufacturers are focusing on optimizing each stage of PCB production, especially the cleaning process, which requires continuous technological improvements to meet higher quality standards. This not only affects product performance and stability but also significantly promotes the development of the entire electronics manufacturing industry. As electronic devices become increasingly powerful, the quality requirements for PCBs also rise, making the optimization of the PCB cleaning process particularly important.

[0003] In the PCB cleaning process, the traditional method involves assembling a series of components to secure the water baffle, which is then fixed in place. Specifically, first, the nozzle mounting bracket is bonded to the nozzle support, with a square strip attached to the nozzle support for positioning before bonding. Next, the machine body fixing component and the water baffle locking component are bonded to the machine body. Finally, the bonded nozzle mounting bracket is locked to the machine body fixing component. These steps are interconnected, forming a relatively complex installation process that must be strictly followed in sequence to ensure effective water baffle fixation.

[0004] However, traditional methods of fixing water baffles have significant drawbacks. They involve too many connection steps, making assembly overly complicated and inconvenient. Excessive connecting and bonding not only increases labor and time costs but also increases the risk of errors during operation, affecting the fixation quality of the water baffle and the effectiveness of subsequent cleaning processes. Utility Model Content

[0005] The purpose of this application is to provide a fastener for fixing a water baffle.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a fixing member for fixing a water baffle, including a mounting part, a limiting part provided on the mounting part, a snap-fit ​​part provided on the side of the mounting part away from the limiting part, the mounting part, the limiting part and the snap-fit ​​part together forming a first fitting mounting groove for fitting and mounting a nozzle support plate; the mounting part is provided with an extension part corresponding to the snap-fit ​​part, the mounting part, the snap-fit ​​part and the extension part together forming a second fitting mounting groove for fitting and mounting a water baffle.

[0007] By adopting the above technical solution, the fastener, with the first fitting mounting groove formed by the mounting part, the limiting part, and the snap-fit ​​part, can accurately and stably achieve the fitting and installation of the nozzle support plate, ensuring the positional stability of the nozzle support plate after installation. At the same time, the second fitting mounting groove formed by the mounting part, the snap-fit ​​part, and the extension part can reliably fit and fix the water baffle, making the installation connection between the water baffle and the nozzle support plate simpler and more efficient. This simplifies the complicated assembly process of fixing the water baffle in the traditional way, reduces labor and time costs, reduces the probability of operational errors, improves the fixing quality of the water baffle, and thus optimizes the effect of subsequent PCB cleaning processes, helping PCB production in the electronics manufacturing industry to better meet the high-quality standard requirements in the cleaning process.

[0008] Optionally, the end of the snap-fit ​​portion is provided with a mounting guide surface, which faces the opening side of the second fitting mounting groove, and is used to guide the baffle plate to be embedded into the second fitting mounting groove.

[0009] By adopting the above technical solution, when installing the baffle, the installation guide surface at the end of the snap-fit ​​part faces the opening side of the second fitting mounting groove. This allows the baffle to slide smoothly into the groove as it approaches the second fitting mounting groove, eliminating the need for repeated manual alignment and reducing the difficulty of the baffle installation operation, thus improving installation efficiency. Simultaneously, this guiding effect reduces hard collisions between the baffle and the snap-fit ​​part, preventing damage to the baffle or fasteners due to improper installation, ensuring the structural integrity of both, and maintaining the stability of the baffle after fixing. This ensures the baffle functions reliably in subsequent PCB cleaning processes, indirectly contributing to improved cleaning quality and effectiveness.

[0010] Optionally, the snap-fit ​​portion is recessed on the side near the second fitting mounting groove to form a snap-fit ​​groove.

[0011] By adopting the above technical solution, the snap-fit ​​part is recessed on the side near the second fitting mounting groove to form a snap-fit ​​groove. This allows for precise engagement with the corresponding structure of the baffle plate when it is embedded in the second fitting mounting groove, further enhancing the tightness of the connection between the baffle plate and the fixing component. This effectively prevents the baffle plate from loosening or shifting due to vibration, impact, or other factors during use. At the same time, this snap-fit ​​method eliminates the need for additional adhesive or fastening operations, simplifying the installation process. It also disperses the force through the close contact between the groove and the baffle plate, reducing local stress concentration and preventing deformation or damage to the baffle plate or fixing component due to long-term stress. This ensures that the baffle plate continuously and stably performs its water-blocking function during the PCB cleaning process, improving the overall reliability of the process.

[0012] Optionally, the end of the limiting part is provided with a mounting guide slope.

[0013] By adopting the above technical solution, the end of the limiting part is provided with an installation guide slope. During the process of the fixing component being installed onto the nozzle support plate and the nozzle support plate being simultaneously fitted into the first fitting mounting groove, the slope can provide precise guidance for the cooperation between the fixing component and the nozzle support plate. The transition effect of the slope eliminates the influence of deviation when the two are aligned, allowing the fixing component to be smoothly fitted onto the nozzle support plate and the nozzle support plate to be smoothly embedded into the groove, avoiding jamming or misalignment during installation, greatly reducing the difficulty of operation and improving assembly efficiency. At the same time, the guide slope can disperse the contact stress during the installation process, reduce the direct friction and collision damage between the fixing component and the edge of the nozzle support plate, ensure the structural integrity and stability after the two are connected, and ensure that the water baffle is firmly fixed by the fixing component, so as to play a continuous and reliable role in the PCB cleaning process and provide strong support for the stable operation of the cleaning process.

[0014] Optionally, the mounting part, the limiting part, the snap-fit ​​part, and the extension part are integrally injection molded structures.

[0015] By adopting the above technical solution, the mounting part, limiting part, snap-fit ​​part, and extension part adopt an integrated injection molding structure, which can ensure the integrity and structural strength of the connection between the various parts of the fastener, avoid the connection gaps or loosening risks caused by the splicing of parts in the traditional assembly method, and improve the overall load-bearing capacity and stability of the fastener. At the same time, the integrated molding process reduces the individual processing of multiple parts and subsequent assembly steps, simplifies the production process, reduces the accumulation of errors caused by the assembly of multiple parts, ensures the dimensional accuracy of the first and second fitting mounting slots, and is conducive to the precise matching of the fastener with the nozzle support plate and the baffle plate. In addition, it can reduce manual intervention in the production process, improve production efficiency and reduce manufacturing costs, making the fastener more economical while meeting the performance requirements.

[0016] Optionally, the mounting portion and / or the snap-fit ​​portion may have a hollow structure.

[0017] By adopting the above technical solution, a hollow structure is set in the mounting part and / or the snap-fit ​​part, which can reduce the amount of material used and the weight of the fastener while ensuring the overall structural strength of the fastener. This facilitates installation and saves production costs. At the same time, the hollow structure can enhance the structural flexibility of the mounting part and the snap-fit ​​part, so that the fastener has a certain elastic deformation capability when it is fitted with the nozzle support plate. This better adapts to the small dimensional deviations during the installation process, improves the smoothness of assembly and the tightness of the connection. In addition, the hollow structure can also provide ventilation and chip removal space for the mating part of the fastener and the nozzle support plate, avoid the accumulation of moisture or impurities affecting the fixing effect, and ensure the long-term stable use of the fastener in humid environments such as PCB cleaning processes.

[0018] In summary, this application has at least the following beneficial effect: 1. The fastener, utilizing a first fitting mounting groove formed by an mounting part, a limiting part, and a snap-fit ​​part, can accurately and securely fit and install the nozzle support plate, ensuring the positional stability of the nozzle support plate after installation. Simultaneously, the second fitting mounting groove formed by the mounting part, the snap-fit ​​part, and the extension part can reliably fit and fix the water baffle, making the installation connection between the water baffle and the nozzle support plate simpler and more efficient. This simplifies the complex assembly process of traditional water baffle fixing, reduces labor and time costs, lowers the probability of operational errors, improves the fixing quality of the water baffle, and thus optimizes the effect of subsequent PCB cleaning processes, helping PCB production in the electronics manufacturing industry to better meet high-quality standard requirements in the cleaning stage.

[0019] 2. When installing the baffle plate, the installation guide surface at the end of the snap-fit ​​part faces the opening of the second fitting mounting groove. This guide surface allows the baffle plate to slide smoothly into the groove as it approaches the groove, eliminating the need for repeated manual alignment and reducing the difficulty of installation, thus improving efficiency. Simultaneously, this guiding effect reduces hard collisions between the baffle plate and the snap-fit ​​part, preventing damage to the baffle plate or fasteners due to improper installation, ensuring the structural integrity of both, and maintaining the stability of the baffle plate after fixing. This ensures the baffle plate functions reliably in subsequent PCB cleaning processes, indirectly contributing to improved cleaning quality and effectiveness. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] In this embodiment, refer to Figures 1-2 The fixing component for fixing a water baffle provided in this application embodiment includes an installation part 1, a limiting part 2, a snap-fit ​​part 3, and an extension part 6. The installation part 1 is provided with a limiting part 2, and the side of the installation part 1 away from the limiting part 2 is provided with a snap-fit ​​part 3. The installation part 1, the limiting part 2, and the snap-fit ​​part 3 together form a first fitting installation groove 5 for fitting and installing a nozzle support plate 4. The installation part 1 is provided with an extension part 6 corresponding to the snap-fit ​​part 3. The installation part 1, the snap-fit ​​part 3, and the extension part 6 together form a second fitting installation groove 8 for fitting and installing a water baffle 7. The fixing component makes it easy to install the water baffle 7 on the nozzle support plate 4, improving the convenience and stability of the installation.

[0024] Specifically, mounting part 1 is the foundation of the entire fastener, providing support for the installation and connection of other parts. Mounting part 1 can be made of high-strength plastic, which has good wear resistance and corrosion resistance, ensuring that the fastener will not be damaged during long-term use. The shape of mounting part 1 can be designed according to actual needs, generally a plate-like structure. Its surface can be designed to be flat, or it can have some protrusions or grooves to increase friction with other components. For example, the surface of mounting part 1 can be designed with a fine textured structure, which allows for better fixation of the baffle plate 7 and the nozzle support plate 4 during installation.

[0025] The limiting part 2 is provided on the mounting part 1. Its main function is to limit the position of the mounting component on the nozzle support plate 4, preventing the fixing component from shaking or shifting after installation. The limiting part 2 can be manufactured integrally with the mounting part 1, which can ensure the connection strength between them. The end of the limiting part 2 is provided with a mounting guide slope 11. The function of this slope is to guide the fixing component when it is installed as a whole onto the nozzle support plate 4, making it easier for the mounting part 1 to be installed onto the nozzle support plate 4 and for the nozzle support plate 4 to be more easily embedded into the first fitting mounting groove 5.

[0026] The snap-fit ​​portion 3 is located on the side of the mounting portion 1 away from the limiting portion 2. Together with the mounting portion 1 and the extension portion 6, it forms the second fitting mounting groove 8 for mounting the baffle plate 7. The end of the snap-fit ​​portion 3 has a mounting guide surface 9, which faces the opening side of the second fitting mounting groove 8. Its function is to guide the baffle plate 7 to smoothly embed into the second fitting mounting groove 8. The snap-fit ​​portion 3 has a recessed snap-fit ​​groove 10 on the side near the second fitting mounting groove 8. The design of the snap-fit ​​groove 10 increases the friction between the snap-fit ​​portion 3 and the baffle plate 7, allowing the baffle plate 7 to be more securely mounted on the fastener. The snap-fit ​​portion 3 can be made of a material with good elasticity, such as rubber or elastic plastic, thus better achieving the snap-fit ​​function when installing the baffle plate 7.

[0027] The extension 6 is an extension of the mounting part 1 corresponding to the snap-fit ​​part 3. It, together with the mounting part 1 and the snap-fit ​​part 3, forms the second fitting mounting groove 8. The length and shape of the extension 6 can be designed according to the size of the baffle plate 7. Generally, the length of the extension 6 should be long enough to ensure full contact with the baffle plate 7. The extension 6 can be integrally formed with the mounting part 1, or it can be fixed to the mounting part 1 by welding or other connection methods.

[0028] The mounting part 1, limiting part 2, snap-fit ​​part 3, and extension part 6 work together to form a complete fastener structure. The mounting part 1 provides support for the entire structure, the limiting part 2 ensures stable installation of the mounting part 1, and the snap-fit ​​part 3 and extension part 6 securely install the baffle plate 7. This structural design simplifies and facilitates the installation between the baffle plate 7 and the nozzle support plate 4, reducing assembly steps and improving work efficiency. Furthermore, the one-piece molding structure enhances the strength and stability of the fastener, allowing it to better adapt to the requirements of the working environment.

[0029] In addition, to reduce the weight and cost of the fasteners, the mounting part 1 and / or the snap-fit ​​part 3 are provided with a perforated structure 12. The perforated structure 12 can be designed in various shapes, such as circular, square, or polygonal. The size and number of perforated structures 12 can be adjusted according to the actual needs of the fasteners, minimizing their weight while ensuring the strength of the fasteners. For example, some circular perforated holes can be designed on the mounting part 1, and the size and spacing of these holes can be designed according to the dimensions and strength requirements of the mounting part 1.

[0030] The implementation principle of this embodiment is as follows: The one-piece molded structure of the fastener simplifies the installation steps of the baffle plate 7 and the nozzle support plate 4, reducing the excessive adhesive and connection steps in traditional installation methods and improving installation convenience. The installation guide slope 11 of the limiting part 2 and the installation guide curved surface 9 of the snap-fit ​​part 3 make the installation of the baffle plate 7 and the nozzle support plate 4 easier, while the design of the snap-fit ​​groove 10 increases the stability of the snap-fit. The hollow structure 12, while ensuring the strength of the fastener, reduces its weight and lowers costs. Compared with traditional fastening methods, this fastener design is more stable and easier to install, offering significant advantages and representing an important improvement over existing technology.

[0031] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
