It can automatically complete welding operations without much human intervention and plays a vital role in modern manufacturing, especially in industries such as electronics, automobiles, and machinery.

[0003] Existing automatic welding equipment for PCBA board production generates a large amount of harmful gases during the welding process. These harmful gases may be inhaled by workers and pose health risks. Furthermore, if the generated harmful gases are released directly into the atmosphere without purification, they will pollute the atmosphere. Therefore, an automatic welding equipment for PCBA board production is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic welding device for PCBA board production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding device for PCBA board production, comprising a welding platform and a combined plate, wherein a purification device is provided inside the combined plate, the purification device comprising a fixing collar, an electric telescopic rod fixedly connected inside the fixing collar, a protective collection cover fixedly connected to the telescopic end of the electric telescopic rod, an air duct fixedly connected inside the protective collection cover, a mounting base fixedly connected to the inner wall of the combined plate, a fan fixedly connected to the top of the mounting base, two adjusting grooves opened on the inner wall of the protective collection cover, a filter screen slidably connected to the inner wall of the two adjusting grooves, a scraper ring fixedly connected to the bottom of the filter screen, a purification box slidably connected to the inner wall of the two adjusting grooves, an installation cover inserted into the inner wall of the purification box, two mounting nails inserted into the top of the purification box, and a limit ring fixedly connected to the surface of the telescopic end of the electric telescopic rod.

[0006] By setting up the above structure, when harmful gases are generated during the soldering of PCBA boards under the combined action of the soldering head and solder wire, the harmful gases will first pass through the filter screen for filtration. The filtered harmful gases will then pass through the purification chamber and come into contact with the activated carbon in the chamber, where they will be adsorbed by the activated carbon, thus achieving purification of the harmful gases. This prevents the harmful gases from being directly discharged into the atmosphere and polluting the environment, while also ensuring that the harmful gases are not inhaled by workers, thereby protecting their health. When the purification device needs to clean the filter screen to ensure its filtration effect, replace the activated carbon to ensure the purification efficiency of harmful gases, or clean impurities or solder dross adhering to the surface of the soldering head, the electric telescopic rod can move the filter screen, scraper ring, and purification chamber from the bottom of the protective collection cover. During the movement, the scraper ring can clean the impurities or solder dross adhering to the surface of the soldering head. At the same time, it is convenient for workers to clean the filter screen and replace the activated carbon from the outside, thereby ensuring the filtration effect of the filter screen and the purification efficiency of the purification chamber, thus ensuring the filtration and purification functions of the purification device.

[0007] As a preferred embodiment, the welding platform is provided with a side column on its side, and the side column is provided with a first adjustment component on its side, the surface of the first adjustment component being fixedly connected to the surface of the combined plate.

[0008] As a preferred embodiment, the composite board has a solder reservoir inside, a connecting rod at the bottom of the solder reservoir, a welding head at the bottom of the connecting rod, and two solder wires on the surface of the welding head.

[0009] As a preferred embodiment, the bottom of the fixing collar is fixedly connected to the inner wall of the combined plate, the electric telescopic rod passes through the combined plate, the air duct passes through the combined plate, and the bottom of the fan is fixedly connected to the top of the air duct.

[0010] As a preferred embodiment, the scraper ring is sleeved on the surface of the welding head, and the two mounting pins are fixedly connected to the mounting cover.

[0011] As a preferred embodiment, a control console is provided on the other side of the welding platform, and a second adjustment component is provided on the top of the welding platform, with a PCBA welding plate provided on the top of the second adjustment component.

[0012] By setting up a protective collection cover, the internal filter screen, purification box and other components can be protected, and the internal functions of collecting, filtering and purifying harmful gases will not be easily affected by the outside world, thus providing a stable purification environment for the purification device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by incorporating a filter screen, a purification chamber, an electric telescopic rod, and a scraper ring, addresses the issue of harmful gases generated during PCBA board soldering under the combined action of the soldering head and solder wire. The harmful gases are first filtered through the filter screen, then pass through the purification chamber where they come into contact with activated carbon and are adsorbed, thus purifying the gases. This prevents the harmful gases from being directly released into the atmosphere and polluting the environment, while also ensuring that workers do not inhale them, thus protecting their health. When the purification device needs cleaning the filter screen to maintain its filtration efficiency, replacing the activated carbon to ensure effective purification of harmful gases, or cleaning impurities or solder dross adhering to the soldering head surface, the electric telescopic rod moves the filter screen, scraper ring, and purification chamber from the bottom of the protective collection cover. During this movement, the scraper ring removes impurities or solder dross adhering to the soldering head surface. Simultaneously, workers can easily clean the filter screen and replace the activated carbon from the outside, ensuring the filtration effect of the filter screen and the purification efficiency of the purification chamber, thereby guaranteeing the filtration and purification functions of the purification device.

[0015] This invention, by setting up a protective collection cover, can protect the internal components such as the filter screen and purification box, and can prevent the internal functions of collecting, filtering and purifying harmful gases from being easily affected by the outside world, thereby providing a stable purification environment for the purification device.

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides an automatic welding device for PCBA board production, including a welding platform 1 and a combined plate 4. A purification device 9 is installed inside the combined plate 4. The purification device 9 includes a fixing collar 901, an electric telescopic rod 902 fixedly connected inside the fixing collar 901, a protective collection cover 903 fixedly connected to the telescopic end of the electric telescopic rod 902, a duct 904 fixedly connected inside the protective collection cover 903, a mounting base 905 fixedly connected to the inner wall of the combined plate 4, and a fan 906 fixedly connected to the top of the mounting base 905. The inner wall of the protective collection cover 903... Two adjustable slide grooves 907 are provided, and filter screens 908 are slidably connected to the inner walls of the two slide grooves 907. A scraper ring 909 is fixedly connected to the bottom of the filter screen 908. A purification box 910 is slidably connected to the inner walls of the two slide grooves 907. An installation cover 911 is inserted into the inner wall of the purification box 910, and two installation nails 912 are inserted into the top of the purification box 910. A limit ring 913 is fixedly connected to the surface of the telescopic end of the electric telescopic rod 902. By setting up the filter screen 908, purification box 910, electric telescopic rod 902, and scraper ring 909, the welding head 7 and solder wire 8 work together. When harmful gases are generated during PCBA board soldering, they are first filtered through filter 908. The filtered gases then pass through purification chamber 910 and come into contact with activated carbon within it, where they are adsorbed, thus purifying the harmful gases. This prevents the harmful gases from being directly released into the atmosphere and polluting the environment, while also ensuring that workers do not inhale them, thereby protecting their health. When cleaning filter 908 to maintain its filtration efficiency and replacing activated carbon is necessary, the process can be repeated. When purifying harmful gases and cleaning impurities or tin dross adhering to the surface of the solder head 7, the electric telescopic rod 902 can move the filter screen 908, scraper ring 909 and purification box 910 from the bottom of the protective collection cover 903. During the movement, the scraper ring 909 can clean the impurities or tin dross adhering to the surface of the solder head 7. At the same time, it is convenient for the staff to clean the filter screen 908 and replace the activated carbon from the outside, thereby ensuring the filtration effect of the filter screen 908 and the purification efficiency of the purification box 910, thus ensuring the filtration and purification functions of the purification device 9.

[0023] The welding platform 1 has a side column 2 on its side, and the side column 2 has a first adjustment component 3 on its side. The surface of the first adjustment component 3 is fixedly connected to the surface of the combination plate 4.

[0024] The interior of the composite board 4 is provided with a solder storage box 5, the bottom of the solder storage box 5 is provided with a connecting rod 6, the bottom of the connecting rod 6 is provided with a welding head 7, and the surface of the welding head 7 is provided with two solder wires 8.

[0025] The bottom of the fixing collar 901 is fixedly connected to the inner wall of the combination plate 4, the electric telescopic rod 902 passes through the combination plate 4, the air duct 904 passes through the combination plate 4, and the bottom of the fan 906 is fixedly connected to the top of the air duct 904.

[0026] The scraper ring 909 is fitted onto the surface of the welding head 7, and the two mounting pins 912 are fixedly connected to the mounting cover 911.

The top of the second adjustment component 11 is equipped with a PCBA welding plate 12. By setting a protective collection cover 903, the protective collection cover 903 can protect the internal filter screen 908, purification box 910 and other components, and can ensure that the internal collection, filtration and purification functions of harmful gases are not easily affected by the outside world, thereby providing a stable purification environment for the purification device 9.

[0028] The working principle and usage process of this utility model are as follows: The PCBA board is placed on the PCBA soldering plate 12. The second adjustment component 11 moves and adjusts the PCBA soldering plate 12 to a position below the soldering head 7. Under the combined action of the soldering head 7 and the solder wire 8, the PCBA board can be soldered. When harmful gases are generated during the soldering of the PCBA board, these gases rise and enter the protective collection hood 903. The harmful gases and dust impurities in the air entering the protective collection hood 903 first pass through the filter screen 908, which filters the harmful gases and dust impurities. The filtered harmful gases then pass through the purification chamber 910 and come into contact with the activated carbon in the purification chamber 910. The porous structure of the activated carbon can absorb... The system collects harmful gases, thereby purifying them. The purified gas enters the duct 904 from inside the protective collection cover 903, and is then discharged into the atmosphere by the fan 906. When the purification device 9 needs to clean the filter screen 908, replace the activated carbon, or clean the impurities or solder dross adhering to the surface of the solder joint 7, the electric telescopic rod 902 is activated to move the filter screen 908, scraper ring 909, and purification box 910 from the bottom of the protective collection cover 903. During the movement, the scraper ring 909 can clean the impurities or solder dross adhering to the surface of the solder joint 7, while the filter screen 908, which moves to the outside, is easy for staff to clean, and the purification box 910, which moves to the outside, is easy for staff to replace the activated carbon.
