Description

Technical Field

[0001] The utility model relates to the technical field of electric soldering iron equipment, and in particular discloses an electric soldering iron handle with a planar heat transfer structure, an electric soldering iron and welding equipment. Background Art

[0002] Soldering iron is a very commonly used electronic tool. Its main purpose is to melt tin and then combine electronic components and PCB boards together. According to the different heat transfer methods (that is, the heat from the heating core is transferred to the soldering iron tip), the commonly used electric soldering irons on the market are divided into two types: internal heating type and external heating type. The internal heating type is that the soldering iron tip has a hole, and the heating core extends into the soldering iron tip. The external heating type is that the heating core is a tubular structure, and the soldering iron tip is placed inside the heating core. Due to the limitations of the heating core structure and technical process, it is difficult to achieve a close fit between the heating core and the soldering iron tip, which leads to low heat transfer efficiency. For some cases where the amount of tin that needs to be melted is relatively large, the power of the soldering iron must be increased. Whether it is an internal heating electric soldering iron or an external heating electric soldering iron, their high-power soldering irons need to make the heating core very large, so that the size of the operating handle will be very large, and the large size will make it inconvenient for personnel to operate.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Figure 1 and Figure 2 The schematic structural diagram of an embodiment of the electric soldering iron handle with a planar heat transfer structure of the utility model is shown. Figure 1 It is a schematic diagram of the overall structure of the electric soldering iron handle with a planar heat transfer structure. Figure 2 is a schematic diagram of the decomposition structure. Figure 1 and Figure 2 As shown, the electric soldering iron handle with a planar heat transfer structure includes: a soldering iron tip 1, a planar heating core assembly 2, a heating core fixing tube 3 and a handle assembly 4.

[0022] The flat heating core assembly 2 is arranged in the handle assembly 4, and the end of the soldering iron tip 1 is arranged as a flat contact portion 11 matching the flat heating core assembly 2, and the flat contact portion 11 is in close contact with the plane of the flat heating core assembly 2. The heating core fixing tube 3 is sleeved on the end of the soldering iron tip 1 and the flat heating core assembly 2, and is respectively connected to the soldering iron tip 1 and the handle assembly 4, and is used to fix the soldering iron tip 1, the flat heating core assembly 2 and is connected to the handle assembly 4.

[0023] In this embodiment, a flat heating core component 2 is adopted and the end of the soldering iron tip 1 is set as a flat contact portion 11, so that the flat heating core component 2 and the flat contact portion 11 are in close contact with each other, which greatly increases the contact area between the flat heating core component 2 and the flat contact portion 11, so that the heat generated by the flat heating core component 2 can be quickly transferred to the soldering iron tip 1 through the flat contact portion 11, greatly improving the heat conduction efficiency. The higher the heat conduction efficiency, the smaller the heat loss, and the faster the heating speed of the soldering iron tip 1, so that the soldering iron tip 1 can quickly reach the required welding temperature.

[0024] Furthermore, in order to facilitate replacement of the soldering iron tip 1 and the planar heating core assembly 2, the soldering iron tip 1 and the heating core fixing tube 3 are detachably connected, and the heating core fixing tube 3 and the handle assembly 4 are detachably connected.

[0025] Specifically, the soldering iron tip 1 and the heating core fixing tube 3 are detachably connected, so that the soldering iron tip 1 can be conveniently and quickly removed from the heating core fixing tube 3 for cleaning or replacement. In addition, the heating core fixing tube 3 and the handle assembly 4 are detachably connected, so that the heating core fixing tube 3 can be removed from the handle assembly 4, and then the heating core assembly in the heating core fixing tube 3 can be replaced.

[0026] Furthermore, a first external thread (not shown in the figure) is provided on the side of the planar contact portion 11, a first internal thread (not shown in the figure) matching the first external thread is provided on the inner surface of the heating core fixing tube 3, the planar contact portion 11 is screwed to the heating core fixing tube 3, a second external thread (not shown in the figure) is provided on the outer surface of the heating core fixing tube 3, a second internal thread (not shown in the figure) matching the second external thread is provided on the inner surface of one end of the handle assembly 4, and the heating core fixing tube 3 is screwed to the handle assembly 4.

[0027] Furthermore, the planar heating core assembly 2 includes a planar heating core 21 and a heat insulating sheet 22 , one side of the planar heating core 21 is in close contact with the planar contact portion 11 , and one side of the heat insulating sheet 22 is in close contact with the other side of the planar heating core 21 .

[0028] Specifically, the planar heating core 21 is arranged in the heating core fixing tube 3 and one side thereof is in close contact with the planar contact portion 11, and one side of the heat insulation sheet 22 is in close contact with the other side of the planar heating core 21, which is used to separate the planar heating core 21 and the handle assembly 4 to prevent the heat emitted by the planar heating core 21 from being transferred to the handle assembly 4, thereby preventing the handle assembly 4 from overheating and scalding the user on the one hand, and preventing high temperature from damaging the internal components of the handle assembly 4 on the other hand.

[0029] Furthermore, a control board 41 is disposed in the handle assembly 4 , and the control board 41 is electrically connected to the planar heating core 21 .

[0030] Specifically, the control board 41 is used to control the start and stop of the electric soldering iron.

[0031] Furthermore, a mounting portion is provided on the other side of the heat insulation sheet 22 , and a temperature sensor is provided in the mounting portion. The temperature sensor is electrically connected to the control board 41 .

[0032] Specifically, by arranging a temperature sensor at the heat insulation sheet 22, the temperature sensor can monitor the temperature information of the electric soldering iron in real time and transmit the temperature information to the control board 41. The control board 41 adjusts the temperature of the electric soldering iron according to the temperature information transmitted by the temperature sensor.

[0034] Specifically, the metal soldering tip 1 is one of a copper soldering tip 1, a stainless steel soldering tip 1, a tungsten steel soldering tip 1, and a lithium-magnesium alloy soldering tip 1, and the utility model does not limit it. The metal soldering tip 1 has the characteristics of long service life, good corrosion resistance, fast heating, and uniform heat conduction, and is suitable for large-scale welding work. The ceramic soldering tip 1 has poor thermal conductivity, but its surface is flat and not easily contaminated, and is suitable for welding small parts and delicate work.

[0035] Furthermore, the electric soldering iron handle with a planar heat transfer structure also includes a heat conductive sheet 23 that matches the end of the soldering iron tip 1 and the planar heating core assembly 2 , and the heat conductive sheet 23 is disposed between the end of the soldering iron tip 1 and the planar heating core assembly 2 .

[0036] Specifically, the heat conducting sheet 23 is disposed between the soldering iron tip 1 and the planar heating core assembly 2. It should be understood that when the soldering iron tip 1 is a metal soldering iron tip 1, an insulating heat conducting sheet 23 needs to be added between the soldering iron tip 1 and the planar heating core assembly 2 to prevent leakage. When the soldering iron tip 1 is a ceramic soldering iron tip 1, the soldering iron tip 1 itself has insulating properties, and no insulating heat conducting sheet 23 needs to be added.
