Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The soldering iron device 100 of this utility model is described below with reference to the accompanying drawings.

[0033] Reference Figure 1 According to an embodiment of the present invention, a soldering iron device 100 is provided, which includes two soldering iron tips 10 and an elastic element 20.

[0034] Two soldering iron tips 10 are pivotally connected. An elastic element 20 is disposed between the two soldering iron tips 10 and connects the two soldering iron tips 10 respectively, so that the first included angle between the two soldering iron tips 10 tends to increase.

[0035] The two soldering iron tips 10 are connected, and the included angle between the two soldering iron tips 10 can be changed. This reduces the difficulty of operation and improves the convenience for surface mount components that are soldered at both ends at the same time.

[0036] In related technologies, a soldering iron is a tool used to melt solder during welding. It contains a heating element with a soldering tip attached. The soldering tip conducts heat to the solder, melting it and allowing it to flow between two workpieces. However, the operation of soldering iron devices in related technologies is rather cumbersome.

[0037] Specifically, in the relevant technology, the two soldering iron tips need to be held by the operator's two hands respectively, and the soldering iron device cannot be operated with one hand.

[0038] In practical applications, especially during the R&D process of PCBA products, it is often necessary to replace components on the PCBA for debugging. Currently, common soldering irons require simultaneous soldering at both ends when handling surface-mount components (such as surface-mount resistors or capacitors), which is quite difficult. Hot air guns can also be used, but these methods have drawbacks, such as blowing away other components and prolonged use affecting PCBA performance. The soldering iron device proposed in this application can directly pick up and solder or remove surface-mount components that need simultaneous soldering at both ends. Compared to traditional soldering irons, this solution is simpler to operate, saves debugging time, and improves R&D efficiency to a certain extent. Compared to hot air guns, this solution causes less damage to the PCBA and is less likely to damage the corresponding hardware.

[0039] In this embodiment of the utility model, by setting an elastic element 20 between the two soldering iron tips 10, the first included angle between the two soldering iron tips 10 is automatically increased by the elastic element 20. When the operator does not apply force, the two soldering iron tips 10 automatically open. When the operator applies force, the elastic force of the elastic element 20 is overcome and the two soldering iron tips 10 are brought closer together, realizing one-handed operation, simplifying operation and improving convenience.

[0040] For example, the elastic element 20 can be a spring, with its two ends connected to two soldering iron tips 10, and the spring applies a spring force to the two soldering iron tips 10; or, the elastic element 20 can be a torsion spring, with the torsion spring connected to the two soldering iron tips 10, and the torsion spring applies a spring force to the two soldering iron tips 10. Of course, the elastic element 20 can also be other types, which will not be elaborated here.

[0041] According to the embodiment of the present invention, the soldering iron device 100 provides an elastic element 20 between two soldering iron tips 10. The elastic force of the elastic element 20 causes the first included angle between the two soldering iron tips 10 to automatically increase, and the two soldering iron tips 10 to automatically open. The operator can operate with one hand, which simplifies the operation and improves convenience.

[0042] Reference Figure 1 , Figure 2 In some embodiments, the soldering iron device 100 further includes a support post 30, and the soldering iron tip 10 has a connecting portion 11, which is rotatably connected to the support post 30. The end of the soldering iron tip 10 away from the support post 30 is configured as a working portion 12, which is used to contact the device to be soldered. The part of the elastic member 20 connected to the soldering iron tip 10 is located between the connecting portion 11 and the working portion 12.

[0043] The working part 12 is used to contact the device to be soldered. The working part 12 has heat to melt the solder and achieve soldering. The connecting part 11 on the soldering iron tip 10 is connected to the support column 30, which supports the soldering iron tip 10 and makes the soldering iron tip 10 rotate stably.

[0044] In the above scheme, the soldering iron tip 10 is supported by a support column 30, and the part where the elastic element 20 is connected to the soldering iron tip 10 is located between the connecting part 11 and the working part 12. The support column 30 is a movable fulcrum, which makes the soldering iron tip 10 rotate stably and improves stability.

[0045] Specifically, the connecting part 11 can be a connecting hole, and the support column 30 passes through the connecting hole; or, the connecting part 11 can be a protrusion, and the support column 30 has a groove, and the protrusion is inserted into the groove.

[0046] Reference Figure 1 , Figure 2 In some embodiments, the soldering iron tip 10 includes a soldering iron body 13 and a bent portion 14.

[0047] The working part 12 is located at one end of the soldering iron body 13. The bending part 14 is located on one side of the soldering iron body 13. The bending part has a connecting hole, which is constructed as a connecting part 11. The support column 30 passes through the connecting hole.

[0048] The bending part 14 is provided on the soldering iron body 13, and there is a certain angle between the bending part 14 and the soldering iron body 13. One end of the soldering iron body 13 is constructed as the working part 12. The soldering iron body 13 conducts heat and melts the solder.

[0049] In the above scheme, by opening a connection hole on the bent part 14, the support column 30 passes through the connection hole, so that the soldering iron body 13 can rotate stably.

[0050] Specifically, there are two bending portions 14, which are respectively located on opposite sides of the soldering iron body 13, thereby further increasing stability.

[0051] Reference Figure 1 , Figure 2 In some embodiments, the width of the working part 12 gradually decreases in the direction away from the connection hole.

[0052] In particular, the width of the working part 12 gradually decreases in the direction away from the connecting hole, that is, the working part 12 gradually becomes pointed.

[0053] In the above scheme, by setting the working part 12 to gradually shrink, the working part 12 gradually becomes pointed. The working part 12 can better contact smaller parts and can also pass through smaller gaps, thereby adapting to a variety of working environments and increasing the working range.

[0054] Reference Figures 1 to 3 In some embodiments, the bending portion 14 includes a bending body 142 and an extension portion 143.

[0055] A connecting hole is provided on the bending body 142. An extension body 143 is provided on the bending body 142 and extends toward the working part 12. The width of the extension body 143 gradually decreases in the direction toward the working part 12.

[0056] The bending body 142 is connected to the support column 30 through the connecting hole, and the extension body 143 extending out of the bending body 142 gradually shrinks.

[0057] In the above scheme, by setting the extension body 143, the overall strength of the bending part 14 is increased, and at the same time, the width of the extension body 143 gradually decreases to adapt to the working part 12, so that the soldering iron tip 10 can be inserted into a smaller space, thereby increasing the applicable range.

[0058] Reference Figures 1 to 4 In some embodiments, the soldering iron device 100 further includes a heat-insulated handle 40, which includes a force-receiving part 41 and a protective part 42.

[0059] The force-bearing part 41 is connected to the side of the soldering iron tip 10 away from the support column 30. The force-bearing part 41 is used to bear external forces to change the first included angle. The protective part 42 is provided at one end of the force-bearing part 41.

[0060] The heat-insulating handle 40 is made of heat-insulating material. The force-bearing part 41 is connected to the soldering iron tip 10. The force-bearing part 41 provides a force-bearing surface for the operator's palm. The protective part 42 installed on the force-bearing part 41 does not contact the soldering iron tip 10. The protective part 42 is placed between the operator's palm and the heating body to prevent the palm from being burned.

[0061] In the above solution, by setting the force-receiving part 41 to connect the soldering iron tip 10, the force-receiving part 41 provides a force-applying surface for the operator, thereby keeping a certain distance between the operator's palm and the soldering iron tip 10, avoiding burns to the operator and improving safety.

[0062] Reference Figures 1 to 4 In some embodiments, a second included angle is provided between the protective part 42 and the force-bearing part 41, the second included angle being θ, where 90°≤θ<180°.

[0063] The protective part 42 is inclined relative to the force-bearing part 41, and there is a second included angle between the protective part 42 and the force-bearing part 41.

[0064] In the above scheme, by setting the second included angle θ between the protective part 42 and the force-bearing part 41 in the range of 90° to 180°, the operator can better contact the force-bearing part 41 with one hand and make it easier for the operator to apply force. Under the action of leverage, the first included angle between the two soldering iron tips 10 changes significantly, which further improves convenience.

[0065] For example, the second included angle θ between the protective part 42 and the force-receiving part 41 is 90°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 100°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 110°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 120°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 130°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 140°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 150°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 160°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 170°; or, the second included angle θ between the protective part 42 and the force-receiving part 41 is 179°.

[0066] Reference Figures 1 to 4 In some embodiments, the soldering iron device 100 further includes a heating element 50, which includes a heating element and a heat-conducting element 52.

[0067] The heating element is used to generate heat. The heat-conducting element 52 is partially connected to the heating element and partially connected to the soldering tip 10 to transfer heat.

[0068] The heating element generates heat, and the heat-conducting element 52 connects the heating element and the soldering iron tip 10 respectively, transferring the heat to the soldering iron tip 10 to achieve the hot melting of the solder.

[0069] In the above solution, the heat is transferred from the heating element to the soldering tip 10 through the cooperation of the heating element and the heat-conducting element 52, which makes the soldering tip 10 smaller in size and suitable for various working environments, thus improving its practicality.

[0070] In some embodiments, the heating element and the heat-conducting element 52 are detachably connected.

[0071] The heating element and the heat-conducting element 52 are detachably connected. The heating element and the heat-conducting element 52 are connected to conduct heat. The heating element can also be disconnected from the heat-conducting element 52, and the heat-conducting element 52 and the heating element are separated into two separate components.

[0072] In the above solution, the heating element and the heat-conducting element 52 are detachably connected, and the heating element and the heat-conducting element 52 can be separated and placed separately. At the same time, if one of the parts is damaged, a new part can be quickly replaced, which improves work efficiency.

[0073] Reference Figures 1 to 5 In some embodiments, the heat-conducting element 52 has a mounting hole 521 and a mounting groove 522 at one end. The mounting hole 521 is fitted onto the support column 30. The heating element is constructed as a heating column, which passes through the mounting groove 522. The outer wall of the heat-conducting element 52 is provided with a shell 523.

[0074] The heating element is constructed as a heating column, and the mounting groove 522 on the heat-conducting element 52 corresponds to the heating column. The heating column is inserted into the mounting groove 522 to achieve quick assembly and disassembly. At the same time, the heat-conducting element 52 is sleeved on the support column 30 through the mounting hole 521, and the outer wall of the heat-conducting element 52 is covered with a shell 523 to isolate the heat-conducting element 52.

[0075] In the above scheme, by constructing the heating element as a heating column, the heating column can be quickly inserted into or pulled out of the mounting slot 522, which improves the assembly efficiency. Furthermore, the heating column is in full contact with the mounting slot 522, which improves the heat transfer efficiency.

[0076] Specifically, the outer casing 523 is made of insulating and heat-insulating material, which isolates heat.
