[0001] This utility model relates to the field of soldering iron tips, specifically to a soldering tip and a soldering iron tip. Background Technology

[0002] Currently, in the manufacturing process of mobile phones and other electronic devices, after the chip is attached to the PCB board, manufacturers typically apply adhesive to the bottom to protect and better secure the chip. During subsequent phone repair, this adhesive material must be removed before replacement or repair. Currently, the removal of the adhesive material usually involves using a heat gun to soften the hardened material, followed by scraping it off with a scraper. This process not only uses multiple tools but also carries the risk of localized overheating due to unsuitable heat gun temperature or placement, potentially burning or damaging other components.

[0003] Therefore, providing a soldering tip and soldering iron tip to improve the convenience and safety of sealant removal and simplify the operation has become an urgent technical problem to be solved. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, embodiments of this utility model disclose a welding head, the welding head comprising a head end and a tail end, wherein the width of the head end is greater than the width of the tail end, wherein:

[0007] The head end includes a horizontal bottom surface and an inclined surface. The inclined surface forms a preset acute angle with the horizontal bottom surface to give the head end a pointed tip. The horizontal bottom surface is perpendicular to the radial section of the tail end.

[0026] The present invention will now be described based on embodiments, but the present invention is not limited to these embodiments.

[0030] In the process of removing sealant from PCB boards, a hot air gun is often used to heat the hardened sealant, softening it before scraping it off with a scraper. During this process, it's crucial to control the temperature, airflow, and heating time of the hot air gun to avoid overheating, which could damage the circuit board, burn, or damage other electronic components. Therefore, removing sealant involves using multiple tools such as scrapers and hot air guns, requiring the operation of different tools for each step, making the process complex. After removing the sealant, soldering is performed using tools such as soldering stations and soldering irons. This results in a large number of tools on the repair technician's workbench, taking up valuable workspace and necessitating frequent tool changes throughout the repair process, making the overall repair operation cumbersome.

[0031] To improve the convenience and safety of sealant removal and simplify the operation, this embodiment discloses a welding head. Please refer to... Figure 1 , Figure 1This is a schematic diagram of the structure of a welding head in one direction disclosed in this embodiment. The welding head 10 includes a head end 11 and a tail end 12, wherein the width of the head end 11 is greater than the width of the tail end 12. In this embodiment, the head end 11 can be used to scrape off sealant material. Specifically, the welding head 10 is used by mounting it on the soldering iron tip connecting rod. The heating element inside the soldering iron tip connecting rod heats the welding head 10. Therefore, the welding head 10 can replace a hot air gun to heat the hardened sealant material. After the sealant material has softened, it can be directly scraped off using the head end 11 without the need for scrapers, spatulas, blades, or other tools. This allows for the removal of sealant material with a single tool, thereby improving the convenience of sealant removal and simplifying the sealant removal process.

[0032] Since a certain force needs to be applied to the head end 11 to scrape off the softened sealant when removing the sealant, the width of the head end 11 is designed to be greater than the width of the tail end 12. This increases the force on the head end 11, making the solder head 10 more durable and preventing breakage during the scraping of softened sealant, thus ensuring the service life and safety of the solder head 10. It is understandable that the solder head 10 can be used not only to heat and remove sealant but also for soldering, offering multiple functions. This simplifies the tools needed by maintenance personnel during repairs, thereby simplifying the overall repair operation. In practice, the head end 11 and the tail end 12 can have the same shape or different shapes. For example, both the head end 11 and the tail end 12 can be cylindrical, or one can be cylindrical and the other non-cylindrical.

[0033] like Figure 1 As shown, the head end 11 includes a horizontal bottom surface 111 and an inclined surface 112. The inclined surface 112 forms a preset acute angle with the horizontal bottom surface 111 to give the head end 11 a pointed tip, and the horizontal bottom surface 111 is perpendicular to the radial section of the tail end 12. In this embodiment, after the soldering head 10 is heated, the horizontal bottom surface 111 can be used to approach or directly contact the sealing material to soften it. After the sealing material is softened, the pointed tip formed by the inclined surface 112 and the horizontal bottom surface 111 is used to scrape off the sealing material. In specific implementation, one surface of the head end 11 is the horizontal bottom surface 111, so that when scraping the sealant, the horizontal bottom surface 111 can directly contact the PCB board. When the maintenance personnel operate to scrape off the sealing material, the horizontal bottom surface 111 can distribute the force applied by the maintenance personnel to the contact surface between the horizontal bottom surface 111 and the PCB board, thereby reducing the risk of scratching the PCB board and preventing the PCB copper foil or electronic components from falling off due to excessive force.

[0034] The inclined surface 112 and the horizontal base surface 111 form an acute angle, meaning the head end 11 has a pointed tip. This allows the pointed tip of the head end 11 to directly insert into or scrape off the softened sealant material during application, utilizing the angle between the inclined surface 112 and the horizontal base surface 111. Furthermore, the inclined surface 112 allows the scraped sealant material to slide along it without accumulating at the head end 11, thus reducing scraping resistance and improving ease of operation. Preferably, the acute angle between the inclined surface 112 and the horizontal base surface 111 can be 25°. It should be noted that the acute angle between the inclined surface 112 and the horizontal base surface 111 can refer to an acute angle between the two surfaces, or it can refer to an acute angle between the extension of the inclined surface 112 and the extension of the horizontal base surface 111. In other words, the pointed tip of the head end 11 can be either pointed or blunt.

[0035] The horizontal bottom surface 111 is perpendicular to the radial section of the tail end 12. This means that during adhesive application, the tip of the head end 11 remains in contact with the PCB board, preventing the softened sealant from leaking out through the gap between the horizontal bottom surface 111 and the PCB board, thus improving application efficiency. It should be noted that due to manufacturing tolerances, the horizontal bottom surface 111 and the radial section of the tail end 12 only need to be approximately perpendicular; perfect perpendicularity is not required.

[0036] In an optional embodiment, the tip of the scraper head 11 is provided with a cut surface 113, and the inclined surface 112 and the horizontal bottom surface 111 are respectively connected to the opposite sides of the cut surface 113. In this embodiment, the tip of the scraper head 11 is provided with a cut surface 113, which makes the tip of the scraper head 11 blunt. Compared with the design of the scraper head 11 being pointed, the blunt design makes it less likely to scratch the PCB board during scraping, thereby protecting the PCB board and improving the safety of the PCB board during scraping operations. Furthermore, when the operator cleans the sealant material that has not been removed from the scraper head 11, they will not be scratched by the sharp corner of the scraper head 11. Even if the softened sealant material hardens again, it is easier to remove from the scraper head 11, thereby ensuring the operator's operational safety and improving the convenience of cleaning.

[0037] The inclined surface 112 and the horizontal bottom surface 111 are respectively connected to the opposite sides of the cut surface 113. Specifically, the inclined surface 112 can be connected to one long side of the cut surface 113, and the horizontal bottom surface 111 can be connected to the other long side of the cut surface 113. In other words, the height of the cut surface 113 is not high, so that the sealant material scraped off will not accumulate at the head end 11 when scraping glue, thereby reducing the scraping resistance and improving the ease of operation when scraping glue.

[0038] In an optional embodiment, the connection angle between the cut surface 113 and the horizontal bottom surface 111 is a right angle. In this embodiment, the shape of the cut surface 113 is not limited; that is, the cut surface 113 can be a plane or an irregular surface, as long as the connection angle between the cut surface 113 and the horizontal bottom surface 111 is a right angle. Setting the connection angle between the cut surface 113 and the horizontal bottom surface 111 to a right angle allows for direct and close scraping of the softened sealant material during adhesive application, improving the adhesive application effect.

[0039] In an optional embodiment, the cut surface 113 is a plane perpendicular to the horizontal bottom surface 111, and the head end 11 is trapezoidal in shape. In this embodiment, the cut surface 113 is entirely planar and perpendicular to the horizontal bottom surface 111. Due to the presence of the cut surface 113, the head end 11 is trapezoidal in shape, and the cut surface 113 is the top surface of the trapezoid. Setting the cut surface 113 as a vertical plane facilitates the production and processing of the welding head 10 and also improves the adhesive application effect.

[0040] In optional embodiments, such as Figure 1 As shown, the welding head 11 also includes a transition section 13, which is disposed between the tail end 12 and the head end 11, and the width of the transition section 13 gradually increases from the tail end 12 to the head end 11. In this embodiment, since the width of the tail end 12 is smaller than the width of the head end 11, a transition section 13 is provided between the tail end 12 and the head end 11 for the sake of the overall stability and aesthetics of the welding head 10. The transition section 13 is mainly used to evenly transition the width of the welding head 11 from the narrower width of the head end 11 to the wider width of the tail end 12, so that the welding head 10 is subjected to more uniform force, has a more stable structure, and is more aesthetically pleasing during use.

[0041] In an optional embodiment, the outer periphery of the transition section 13 is a concave curved surface. In this embodiment, the outer periphery of the transition section 13 is a concave curved surface, thereby making the shape of the transition section 13 a truncated cone similar to a trumpet shape. Setting the outer periphery of the transition section 13 as a concave surface forms a nonlinear heat flow path, which can improve the heat conduction efficiency and also reduce the stress concentration factor by inducing stress redistribution through curvature, thereby improving the service life of the welding head 11.

[0042] In optional embodiments, such as Figure 1As shown, the two sides of the tail of the inclined surface 112 move towards the central axis of the tail end 12, which is cylindrical. In this embodiment, the head end 11 of the welding head 11 is trapezoidal, the transition section 13 is a truncated cone similar to a trumpet shape, and the tail end 12 is cylindrical. Therefore, when the transition section 13 is smoothly connected to the end of the head end 11, the tail of the inclined surface 112, that is, the part of the inclined surface 112 near the tail end 12, gradually moves towards the central axis of the tail end 12, thus forming an arc transition. This smooth transition between the transition section 13 and the head end 11 makes the welding head 10 more aesthetically pleasing overall. Furthermore, the overall lines of the welding head 10 are smooth, improving heat conduction efficiency, and it can also induce stress redistribution through curvature, facilitating the maintenance of the welding head 10.

[0043] In an optional embodiment, the tail end 12 is provided with a connecting part that is fastened to the soldering iron tip connecting rod.

[0044] In an optional embodiment, please refer to Figure 2 , Figure 2 This is a schematic diagram of the welding head structure disclosed in this embodiment from another direction. The connecting part includes a connecting cavity 121, and the soldering iron tip connecting rod is at least partially located within the connecting cavity 121 and is securely connected to the welding head 10. In this embodiment, the connecting part is provided with a connecting cavity 121, and the connecting part of the soldering iron tip connecting rod is inserted into the connecting cavity 121 within the tail sleeve 112, thereby achieving a secure connection between the welding head 10 and the soldering iron tip connecting rod within the connecting cavity.

[0045] This embodiment also discloses a soldering iron tip; please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of the structure of a soldering iron tip disclosed in this embodiment. Figure 3 As shown, the soldering iron tip 20 includes a connecting rod 21 and a soldering head 10 as described above. The connecting rod 21 is provided with a heating element for heating the soldering head 10, and the soldering head 10 is fastened to the connecting rod 21.

[0046] A soldering tip and soldering iron tip disclosed according to an embodiment of this utility model include a head end and a tail end, wherein the width of the head end is greater than the width of the tail end. The head end includes a horizontal bottom surface and an inclined surface, with the inclined surface forming a predetermined acute angle with the horizontal bottom surface to give the head end a pointed tip. The horizontal bottom surface is perpendicular to the radial section of the tail end. By using a soldering tip with controllable heating for adhesive removal, other tools required for traditional adhesive removal are eliminated, thereby improving the convenience of adhesive removal and simplifying the process. Furthermore, designing the width of the head end to be greater than the width of the tail end increases the force on the head end, making the soldering tip more durable and capable of scraping off adhesive, preventing breakage during the scraping of softened adhesive, and ensuring the service life and safety of the soldering tip. In addition, the horizontal bottom surface can also distribute the force applied by the repair personnel to the contact surface between the horizontal bottom surface and the PCB board, thereby reducing the risk of scratching the PCB board and preventing the PCB copper foil or electronic components from falling off due to excessive force.
