Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing and repair tools, and more specifically, to a soldering iron with a convenient soldering tip replacement. Background Technology

[0002] A soldering iron is a tool that converts electrical energy into heat energy to solder electronic components, metal wires, or perform other heating operations. However, different soldering tips are required for different components, especially precision electronic components, to improve the soldering effect. Traditional soldering iron tips often maintain a high temperature, making it inconvenient to frequently change the tips.

[0003] In the prior art, Chinese patent publication number CN218362576U discloses "an electric soldering iron, comprising a soldering section, a handheld section, and a tail section connected in sequence, wherein a soldering head is detachably mounted on the soldering section, and the end of the soldering head away from the handheld section has a knife-shaped structure, the knife-shaped structure including a tip for spot soldering and a bevel for correcting solder bridges; the handheld section and the tail section are connected by a telescopic joint, the telescopic joint being used to adjust the angle between the handheld section and the tail section. This electric soldering iron, through the design of the knife-shaped soldering head, facilitates various forms of soldering, and the soldering head is detachably connected to the soldering section, allowing the soldering head to be replaced as needed. In addition, the telescopic joint allows the angle between the handheld section and the tail section to be adjusted according to requirements, facilitating soldering operations with different requirements." However, it still has the following drawbacks: Although the soldering iron has the function of replacing the soldering tip, the soldering tip still needs to be cooled down before it can be replaced. This process not only prolongs the operation time, but also wastes heat. For soldering precision electronic components, frequent replacement of the soldering tip is required, which is not conducive to the operation. Utility Model Content

[0004] The purpose of this invention is to provide a soldering iron with a convenient soldering head replacement, in order to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a soldering iron for easy replacement of soldering tips, including a protective sleeve, a fixing plate is provided inside the protective sleeve, a soldering iron assembly for quick replacement is slidably installed inside the fixing plate, and a cleaning assembly for removing impurities from the soldering tip is provided on one side of the protective sleeve. The soldering iron assembly includes a soldering head slidably mounted inside a fixed plate. Two protrusions are provided around the periphery of the soldering head. Two grooves are formed inside the fixed plate. The two protrusions are slidably mounted in the two grooves. A protrusion is welded to the top of each of the two protrusions. A threaded post is welded to the top of the soldering head. A sleeve is threadedly connected to the periphery of the threaded post. A heating element is installed inside the sleeve. A heat insulation pad is provided around the periphery of the sleeve. A heat insulation layer is provided inside the sleeve.

[0006] As a preferred technical solution of this utility model, the cleaning component includes a fixing block welded to the periphery of the protective cover, a rotating rod connected internally to the fixing block, two rotating rods, a knob welded to one side of each of the two rotating rods, a clamping plate slidably installed on the periphery of the two rotating rods, and a cleaning pad provided on one side of the fixing block.

[0007] As a preferred technical solution of this utility model, the welding head is provided with a plating layer on its periphery, and the welding head is provided with a plurality of holes on its periphery.

[0008] As a preferred technical solution of this utility model, a microcontroller and a relay are installed on the inner top of the sleeve.

[0011] As a preferred embodiment of this invention, a temperature sensor is installed on the periphery of the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By inserting the soldering tip into the protective sleeve and sliding the two protrusions into the two grooves, the sleeve is rotated. The rotation of the sleeve causes the threaded post connected to it to move. The threaded post drives the soldering tip to move, separating the soldering tip from the sleeve. This allows for safe replacement of the soldering tip without cooling. The separated soldering tip is then fixed. The heating element heats the soldering tip, and the heat insulation layer reduces heat transfer from the sleeve to the outside, preventing burns to the user's hands. 2. Using the cleaning components, place the welding head on one side of the cleaning pad, then rotate the welding head to make it fit against the cleaning pad. The cleaning pad can scrape away impurities on the welding head. When the cleaning pad needs to be replaced, turn the knob. The knob drives the rotating rod to rotate. The rotating rod moves within the threaded fixed block and drives the clamping plate to move. The clamping plate can be used to fix or loosen the cleaning pad for easy replacement.

[0019] like Figure 1 As shown, this embodiment proposes a soldering iron with a convenient soldering tip replacement, including a protective sleeve 1, a fixing plate 2 is provided inside the protective sleeve 1, a soldering iron assembly 3 for quick replacement is slidably installed inside the fixing plate 2, and a cleaning assembly 4 for removing impurities from the soldering tip 301 is provided on one side of the protective sleeve 1. like Figure 3 and Figure 4 As shown, the soldering iron assembly 3 includes a soldering head 301 slidably mounted on the inner side of the fixing plate 2. Two protrusions 302 are provided on the periphery of the soldering head 301. Two grooves 303 are provided inside the fixing plate 2. The two protrusions 302 are slidably mounted in the two grooves 303. A protrusion 304 is welded to the top of each of the two protrusions 302, which restricts the movement range of the soldering head 301 and fixes it. A threaded post 305 is welded to the top of the soldering head 301. A sleeve 306 is threadedly connected to the periphery of the threaded post 305. A heating element 307 is installed inside the sleeve 306. A heat insulation pad 308 made of silicone is provided on the periphery of the sleeve 306. 08 can reduce heat transfer to the outside and make it easy for users to handle. The sleeve 306 has an internal heat insulation layer 309 made of magnesium oxide. When in use, the welding head 301 is inserted into the protective sleeve 1, and the two protrusions 302 are slidably installed in the two grooves 303. Then, the sleeve 306 is rotated. The rotation of the sleeve 306 causes the threaded post 305 connected to it to move. The threaded post 305 drives the welding head 301 to move, so that the welding head 301 is separated from the sleeve 306. The welding head 301 can be safely replaced without cooling. The separated welding head 301 is fixed. The heating core 307 can heat the welding head 301. The heat insulation layer 309 can reduce the heat transfer from the sleeve 306 to the outside and prevent the user's hands from being burned.

[0020] like Figure 5As shown, the cleaning component 4 includes a fixing block 401 welded to the periphery of the protective sleeve 1. Two rotating rods 402 are threadedly connected to the inside of the fixing block 401. A knob 403 is welded to one side of each of the two rotating rods 402. Clamping plates 404 are slidably mounted on the periphery of the two rotating rods 402 for fixing a cleaning pad 405. A cleaning pad 405, made of copper wire, is provided on one side of the fixing block 401 and can be used to grind and remove surface imperfections from the welding head 301. To remove impurities, place the welding head 301 on one side of the cleaning pad 405 during use, then rotate the welding head 301 to make it fit against the cleaning pad 405. The cleaning pad 405 can scrape away the impurities on the welding head 301. When the cleaning pad 405 needs to be replaced, turn the knob 403. The knob 403 drives the rotating rod 402 to rotate. The rotating rod 402 moves within the threaded fixed block 401 and drives the clamping plate 404 to move. The clamping plate 404 is used to fix or loosen the cleaning pad 405 for easy replacement.

[0021] like Figure 3 As shown, a plating layer 5 is provided on the periphery of the welding head 301. The plating layer 5 is made of copper. Several holes 6 are opened on the periphery of the welding head 301. There are four holes 6. When in use, the plating layer 5 can increase the heat conduction efficiency and protect the welding head 301.

[0022] like Figure 3 As shown, a microcontroller 7 and a relay 8 are installed on the inner top of the sleeve 306. The microcontroller 7 is an STM32F103C8T6, and the relay 8 is a Songle SRD-05VDC-SL-C. During use, the microcontroller 7 can be used for timing. When the equipment has been used for a long time, the relay 8 will turn off the soldering iron to prevent the user from forgetting to turn off the power and causing a fire.

[0023] like Figure 1 As shown, the protective sleeve 1 has an observation port 9 installed inside. The observation port 9 is made of glass. An adhesive 10 is provided at the joint between the observation port 9 and the protective sleeve 1. The adhesive 10 is made of silicone structural adhesive. During use, the welding head 301 can be observed through the observation port 9, which makes it convenient to select the required welding head 301.

[0024] like Figure 5 As shown, a warning light 11 is installed on the periphery of the sleeve 306. The warning light 11 is coaxially installed with the protective sleeve 1. When in use, the warning light 11 reminds the user that the equipment is working, preventing the user from being burned by the welding head 301.

[0025] like Figure 1 As shown, a temperature sensor 12 is installed on the periphery of the sleeve 306. The temperature sensor 12 is a UNI-T UT325F. During use, the temperature sensor 12 displays the current temperature to facilitate the user's operation.

[0026] Specifically, when using this soldering iron with a convenient soldering tip replacement: The soldering tip 301 is inserted into the protective sleeve 1, and the two protrusions 302 are slidably installed in the two grooves 303. Then, the sleeve 306 is rotated. The rotation of the sleeve 306 causes the threaded post 305 connected to it to move. The threaded post 305 drives the soldering tip 301 to move, separating the soldering tip 301 from the sleeve 306. This allows for safe replacement of the soldering tip 301 without cooling. The separated soldering tip 301 is then fixed in place. The heating core 307 heats the soldering tip 301, and the heat insulation layer 309 reduces heat transfer from the sleeve 306 to the outside, preventing burns to the user's hands (e.g., ...). Figure 3 and Figure 4 (As shown) Place the welding head 301 on one side of the cleaning pad 405, then rotate the welding head 301 to make it fit against the cleaning pad 405. The cleaning pad 405 can scrape away impurities on the welding head 301. When the cleaning pad 405 needs to be replaced, turn the knob 403. The knob 403 drives the rotating rod 402 to rotate. The rotating rod 402 moves within the threaded fixed block 401 and drives the clamping plate 404 to move. The clamping plate 404 is used to fix or loosen the cleaning pad 405 for easy replacement (e.g., Figure 5 (As shown).

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
