Description

Technical Field

[0001] This utility model relates to the field of soldering guns, and more particularly to a soldering gun for electronic engineering. Background Technology

[0002] A soldering gun is a commonly used soldering tool in the field of electronic engineering, mainly used for soldering electronic components and circuit boards. It melts solder through a heating element to achieve a conductive connection. Its structure typically includes a handle, a heating element, and a soldering tip (soldering nozzle). It is easy to operate and can meet the basic soldering needs of electronic assembly and repair scenarios, making it a common tool in the hands of electronic engineers and enthusiasts.

[0003] In the current technology, when operators use soldering guns to solder electronic components such as circuit boards, the soldering gun needs to emit high temperatures to melt the solder bars. When the solder bars melt, fumes containing heavy metals such as lead are emitted. Long-term inhalation can cause harm to the operator's health. At the same time, after the soldering is completed, the barrel of the soldering gun will retain heat for a long time. Therefore, a soldering gun for electronic engineering is proposed to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The mounting bracket is U-shaped.

[0010] As a further description of the above technical solution:

[0011] The barrier assembly includes a connecting rod, the outer wall of which is slidably connected to the inner wall of the support box, and a pressure plate is fixedly connected to the upper surface of the connecting rod, with an arc-shaped groove provided on the upper surface of the pressure plate.

[0012] As a further description of the above technical solution:

[0013] A baffle plate is fixedly connected to the lower surface of the connecting rod, and sliding rods are fixedly connected to both the left and right sides of the inner wall of the support box.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the smoke removal component allows the fumes generated by the welding torch to be drawn into the suction nozzle when the operator is working with the torch. The fumes are then discharged into the air pipe through the main air channel, allowing the harmful gases to be released to the outside and preventing the operator from inhaling gases containing heavy metals for a long time. At the same time, the side air channel will also work simultaneously to draw away the hot air from the torch barrel, increasing the air exchange rate of the torch barrel and enhancing the heat dissipation efficiency of the torch barrel.

[0022] 2. In this utility model, by installing components and blocking components, the smoke removal component can be disassembled by removing bolts during use, making it convenient for operators to replace and maintain the smoke removal component. After the operator finishes using the welding gun, the rotating frame can be rotated to make the baffle plate supported by the spring and blocked at the gas pipe. This allows a single welding gun to be sealed when multiple operators are welding, preventing the smoke removal component from still drawing in gas when a welding gun is not in use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a soldering gun for electronic engineering, comprising a gun body 1 for soldering operations, an installation assembly 3 for easy disassembly and installation on the outer wall of the gun body 1, and a fume extraction assembly 2 on the right surface of the gun body 1 for absorbing fumes emitted during soldering and assisting in heat dissipation of the gun tube; the fume extraction assembly 2 includes a support box 21 for supporting the fume extraction tube 23 and the blocking assembly 4, the left surface of the support box 21 sliding on the right surface of the gun body 1, and an air pipe 22 for connecting the support box 21 to an exhaust fan installed on the left rear surface of the support box 21. The rear surface is provided with a smoke removal component 2 and a blocking component 4 to block individual smoke when multiple people are working. The front surface of the support box 21 is fixedly connected with a smoke removal pipe 23 for accommodating exhaust gas. The inner wall of the front part of the smoke removal pipe 23 is fixedly connected with an air intake 25 for absorbing gas emitted during soldering. The middle of the inner wall of the smoke removal pipe 23 is provided with a main air groove 24 for accommodating harmful gas. The inner wall of the smoke removal pipe 23 is provided with a side air passage 26 for supplying hot air near the left side. The left surface of the smoke removal pipe 23 is provided with multiple heat absorption holes 27 from front to back for absorbing the hot air in the barrel part of the gun body 1.

[0032] Reference Figures 1-3 The mounting assembly 3 includes an extension plate 31 for supporting the mounting bracket 32. The front surface of the extension plate 31 is fixedly connected to the rear surface of the gun body 1. The inner wall of the extension plate 31 is detachably connected to the mounting bracket 32 ​​for supporting the smoke removal assembly 2 by bolts 33. The lower surface of the support box 21 is fixedly connected to the upper surface of the mounting bracket 32. The mounting bracket 32 ​​is U-shaped to make the connection between the mounting bracket 32 ​​and the gun body 1 more stable. The blocking assembly 4 includes a connecting rod 41 for connecting the pressure plate 42 and the blocking plate 44. The outer wall of the connecting rod 41 is slidably connected to the inner wall of the support box 21. The upper surface of the connecting rod 41 is fixedly connected to the pressure plate 42 for easy operation by the operator and to accommodate the rotating frame 46. The upper surface of the pressure plate 42 is provided with an arc groove to make the rotating frame 46 more stable when in contact with the surface of the pressure plate 42.

[0033] Reference Figures 3-5A baffle plate 44 is fixedly connected to the lower surface of the connecting rod 41 to block the operation of the smoke removal assembly 2 without turning off the exhaust fan. Slide rods 43 are fixedly connected to the left and right sides of the inner wall of the support box 21 to limit the movement direction of the baffle plate 44. The inner wall of the baffle plate 44 is slidably connected to the outer wall of the slide rod 43. The rear surface of the baffle plate 44 is in contact with the rear surface of the inner wall of the support box 21. The lower surface of the baffle plate 44 is elastically connected to the lower surface of the inner wall of the support box 21 by a support spring 45 to completely cover the air pipe 22 during daily use. A rotating frame 46 is rotatably connected to the rear surface of the support box 21 to be inserted into the arc-shaped groove of the pressure plate 42 to limit the movement of the pressure plate 42 during use. The upper part of the outer wall of the rotating frame 46 is inserted into the surface of the pressure plate 42. The rotating frame 46 is U-shaped.

[0034] Working principle: When the operator uses the welding gun to weld, first press down the pressure plate 42. The downward movement of the pressure plate 42 drives the connecting rod 41 to move, and at the same time, the blocking plate 44 moves downward along the sliding rod 43. At this time, the support spring 45 is compressed and stores elastic force. Then, rotate the rotating frame 46 so that the rotating frame 46 is inserted into the arc groove of the pressure plate 42. Then turn on the exhaust fan, and the smoke removal assembly 2 starts to work normally.

[0035] During welding, the fumes emitted when the tin melts are collected by the suction nozzle 25 and then move through the main air channel 24 to the support box 21, and finally discharged through the air pipe 22. At the same time, the suction port on the left side of the fume removal pipe 23 will also start working, drawing air from the end near the welding gun barrel into the side air channel 26, so that the hot air around the welding gun barrel can dissipate faster, enhancing the air exchange rate of the device and achieving more efficient heat dissipation. When the fume removal pipe 23 is deformed by external force, the bolts 33 between the mounting bracket 32 ​​and the extension plate 31 can be removed, and the entire fume removal assembly 2 can be removed. The whole process is relatively convenient.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
