[0002] Electronic component processing refers to the process of assembling, connecting, and packaging electronic components into a complete circuit through a series of processes. It mainly includes printed circuit board manufacturing, component mounting, soldering, and testing. Among these processes, soldering is one of the core steps, and the quality of soldering directly affects the reliability and performance of electronic products.

[0003] In the process of soldering electronic components, auxiliary supports are often used to improve the ease of operation. These supports are usually designed with special slots or hooks for placing tools such as soldering irons, solder wire, rosin, and flux, making it easy for workers to access the tools, reducing the problem of tool clutter during the soldering process, and improving work efficiency.

[0004] However, current common welding auxiliary supports only focus on tool storage and lack the ability to handle welding fumes. The fumes generated during welding will directly drift into the air, which not only interferes with the operator's vision and affects welding accuracy, but can also be inhaled into the human body. Long-term exposure may lead to respiratory diseases or heavy metal poisoning. Traditional solutions rely on external ventilation equipment, which is not only bulky but also lacks flexibility. Therefore, an electronic component welding auxiliary support is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0033] Reference Figures 1-3 An embodiment of this utility model provides an auxiliary support for welding electronic components, including a column 1, a base 2 fixedly connected to the bottom of the column 1, a bolt hole 7 on the base 2, and a bolt passing through the bolt hole 7 to fix the base 2 to the welding table. A soldering iron holder 3 is fixedly connected to the upper surface of the base 2 for placing an electric soldering iron. The column 1 is provided with a filtering mechanism and a positioning mechanism 6.

[0034] Reference Figures 2-3 The filtration mechanism includes a dust removal component 4, which includes a slider 41. One end of the slider 41 is slidably connected to the inner wall of the column 1. The height of the bent rod 42 can be adjusted by the slider 41. The other end of the slider 41 is hinged to the bent rod 42. The bent rod 42 can drive the fume hood 43 to swing up and down. The bottom of the bent rod 42 is fixedly connected to the fume hood 43. The fume hood 43 can absorb the fumes generated during the welding process. A hose 44 is fixedly connected to the outer wall of the fume hood 43. The end of the hose 44 away from the fume hood 43 is fixedly connected to the inner wall of the column 1. The fume hood 43 communicates with the interior of the column 1 through the hose 44. A fan 45 is fixedly connected to the inner wall of the column 1. By starting the fan 45, the hose 44 and the lower fume hood 43 can draw external fumes into the interior of the column 1.

[0035] Reference Figure 3 and Figure 5 The top of the column 1 is arranged from bottom to top with a filter screen 46, a filter element 47 and an activated carbon layer 48. The filter screen 46 and the filter element 47 are used to filter solid particles in the smoke and dust, and the activated carbon layer 48 is used to adsorb gaseous pollutants in the smoke and dust. The top of the column 1 is threaded with a pressure cap 49. By rotating the pressure cap 49 to separate it from the column 1, the filter screen 46, the filter element 47 and the activated carbon layer 48 placed on the top of the column 1 can be disassembled for replacement or cleaning. The bottom of the pressure cap 49 is fixedly connected with a sealing gasket 410.

[0036] Reference Figures 3-4 The filtration mechanism also includes a drive assembly 5, which includes a motor 51. The motor 51 is fixedly connected to the top of the slider 41. The output end of the motor 51 is fixedly connected to a rotating shaft 52. The smoke hood 43 starts the motor 51 while extracting smoke and dust, and drives the rotating shaft 52 to rotate. The outer wall of the rotating shaft 52 is fixedly connected to a turntable 53. While the rotating shaft 52 is rotating, it will drive the turntable 53 to rotate synchronously. The outer wall of the turntable 53 is hinged to a connecting rod 54. The end of the connecting rod 54 away from the turntable 53 is hinged to the top side wall of the bent rod 42. While the turntable 53 is rotating, it can work with the connecting rod 54 to drive the bent rod 42 to reciprocate on the inner wall of the slider 41.

[0037] Reference Figures 2-3The positioning mechanism 6 includes a guide rod 61, which is slidably connected to the inner wall of the slider 41. The height of the slider 41 can be fixed by the guide rod 61. A spring 62 is fixedly connected to one end of the guide rod 61. The end of the spring 62 away from the guide rod 61 is fixedly connected to the inner wall of the slider 41. A limit rod 63 is fixedly connected to the other end of the guide rod 61. Pulling the guide rod 61 stretches the spring 62 and moves the limit rod 63 out of the limit hole 65, thus releasing the limit on the slider 41. A limit plate 64 is fixedly connected to the outer wall of the column 1. A limit hole 65 matching the limit rod 63 is opened on the side of the limit plate 64 near the limit rod 63. The limit rod 63 is inserted into the limit hole 65, and the height of the limit rod 63 is limited by the limit hole 65.

[0038] Working principle: When in use, start the fan 45 to blow air upwards. At the same time, the fan 45 will draw air from the inside of the hose 44, causing the hose 44 to draw air from the inside of the fume hood 43. At this time, the fume hood 43 will draw in the fumes generated during the welding process, allowing the fumes to enter the interior of the column 1 through the hose 44. Under the blowing action of the fan 45, the fumes will cover the surface of the filter screen 46. The filter screen 46 can filter out larger solid particles in the fumes. Then, the filter element 47 will filter out fine impurities. Finally, after being purified by the activated carbon layer 48, the fumes are discharged outwards, thus preventing welding fumes from spreading everywhere and affecting the operation and health of the workers.

[0039] While the fume hood 43 is drawing in smoke and dust, the motor 51 is activated, which drives the rotating shaft 52 to rotate. At the same time, the rotating shaft 52 drives the turntable 53 to rotate synchronously. As the turntable 53 rotates, it drives one end of the connecting rod 54 to make a circular motion around the rotating shaft 52. Meanwhile, the other end of the connecting rod 54 pushes and pulls the bent rod 42 back and forth, causing the bent rod 42 to rotate back and forth on the inner wall of the slider 41. As the bent rod 42 rotates back and forth, it drives the fume hood 43 at its bottom end to swing up and down. The up and down swinging of the fume hood 43 can expand its fume extraction range, so that the smoke and dust floating in the air can be fully absorbed by the fume hood 43, thereby improving the smoke and dust treatment effect.

[0040] Pull the guide rod 61 to stretch the spring 62 and move the limiting rod 63 out of the limiting hole 65. At this time, the limiting of the slider 41 can be released. Then push the slider 41 to slide on the inner wall of the column 1. While the slider 41 slides, it can move the fume hood 43 synchronously with the bent rod 42. This allows the height of the fume hood 43 to be adjusted so that the fumes generated by the soldering of electronic components of different heights can be fully absorbed by the fume hood 43, improving the ease of use of the bracket. After the height of the fume hood 43 is adjusted, insert the limiting rod 63 into the limiting hole 65. The height of the limiting rod 63 is limited by the limiting hole 65, thereby fixing the height of the guide rod 61 and the slider 41, and thus fixing the height of the fume hood 43 at the bottom of the bent rod 42.

[0041] 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.
