An activated carbon plate 15 is detachably installed in the water tank 11, and the toxic gas insoluble in water is absorbed by the activated carbon plate 15. Two air outlets 16 are opened on the water tank 11, and the two air outlets 16 are located above the activated carbon plate 15.

[0019] In order to separate the activated carbon plate 15 from the water in the water tank 11 when people are not using the device, and prevent the water vapor generated by the water in the water tank 11 from contacting the activated carbon plate 15, which will cause the water vapor to occupy the adsorption sites of the activated carbon plate 15 and affect the adsorption efficiency of the activated carbon plate 15 for subsequent toxic gases, an isolation funnel 14 is fixedly installed in the water tank 11, and the isolation funnel 14 is located below the activated carbon plate 15, a fixed pipe 18 is fixedly installed in the isolation funnel 14, an annular magnet plate 20 and an annular wind collecting plate 19 are fixedly installed in the fixed pipe 18, and the annular wind collecting plate 19 is located above the annular magnet plate 20, a magnet sealing plate 23 is arranged above the annular magnet plate 20, and two baffles 25 are fixedly installed at the bottom of the annular wind collecting plate 19.

[0020] In order to make the seal between the annular magnet plate 20 and the magnet sealing plate 23 tighter, an annular groove 22 is opened on the top of the annular magnet plate 20, and an annular rubber sealing ring 21 is fixedly installed on the bottom of the magnet sealing plate 23, and the bottom end of the annular rubber sealing ring 21 extends into the annular groove 22.

[0021] In order to guide the magnet sealing plate 23 and the annular rubber sealing ring 21, so that the annular sealing ring 21 can enter the annular groove 22 more smoothly, two guide grooves 26 are opened at the bottom of the annular wind collecting plate 19, and guide rods 24 are respectively slidably installed in the two guide grooves 26, and the two guide rods 24 are fixedly connected to the magnet sealing plate 23.

[0022] In order to absorb water vapor mixed with water-insoluble toxic gases, so that the water-insoluble toxic gases are in a dry state after passing through the desiccant 31, thereby preventing the presence of water vapor from affecting the adsorption effect of the activated carbon plate 15, a lower isolation net 30 is fixedly installed in the fixed tube 18, and a desiccant 31 is arranged on the lower isolation net 30. A mounting plate 28 is fixedly installed in the annular wind gathering plate 19, and a rotating rod 29 is rotatably installed on the mounting plate 28. In order to rotatably install the rotating rod 29 on the mounting plate 28, a rotating hole is opened on the mounting plate 28, and a rotating bearing is fixedly installed in the rotating hole. The rotating rod 29 penetrates the rotating bearing and is fixedly connected to the inner wall of the rotating bearing. The rotating bearing allows the rotating rod 29 to rotate more on the mounting plate 28. The top of the rotating rod 29 extends to the top of the lower isolation net 30, and the rotating rod 29 is rotatably connected with the lower isolation net 30. The rotating rod 29 is fixedly sleeved with a propeller 27 and a plurality of stirring plates 32, and the plurality of stirring plates 32 are all located in the desiccant 31. When the water-insoluble toxic gas quickly enters the fixed tube 18, the water-insoluble toxic gas will push the propeller 27 to rotate, and the rotation of the propeller 27 drives the rotating rod 29 to rotate, and the rotation of the rotating rod 29 drives the stirring plates 32 to rotate to stir the desiccant 31, so that each particle of the desiccant 31 has the opportunity to contact with the water vapor in the mixture of the water-insoluble toxic gas, so that the water-insoluble toxic gas can better contact with the desiccant 31, thereby accelerating the drying process.

[0023] In order to allow the water-insoluble toxic gas to diffuse outward in an umbrella shape and thus come into more comprehensive contact with the activated carbon plate 15, a diffusion hood 17 is detachably installed on the top of the fixed tube 18. In order to prevent the desiccant 31 from entering the diffusion hood 17 and causing unnecessary trouble, an upper isolation net 33 is fixedly installed on the bottom end of the diffusion hood 17.

[0024] The working principle of the PCB circuit board welding device provided by the present invention is as follows: in the initial state, the water tank 11 is filled with water, the bottom end of the U-shaped tube 13 is located below the water level, the magnet sealing plate 23 is adsorbed on the annular magnet plate 20, and then the fixed tube 18 is blocked by the magnet sealing plate 23 and the annular magnet plate 20, and the water and the activated carbon plate 15 are separated by the isolation funnel 14, so that when people do not use the device, the water vapor in the water tank 11 cannot contact the activated carbon plate 15 and the desiccant 31, so that the activated carbon plate 15 is always kept in a dry state. When the circuit board of the device needs to be welded, the circuit board is first placed on the bottom plate 1 in the welding position. Below the gun head 6, the electric push rod 4 is started, and the output shaft of the electric push rod 4 extends downward to drive the cross plate 5 and the welding gun head 6 to move downward, so that the welding gun head 6 contacts the circuit board, and then the welding operation on the circuit board is completed. When toxic mixed gas is generated during the welding process, the suction fan 10 is started, and the suction fan 10 is started to generate suction to absorb the toxic gas into the suction hood 34, and then the toxic mixed gas is transported to the water tank 11 through the annular tube 8, the air inlet pipe 7, the telescopic corrugated connecting pipe 9, the connecting pipe 12 and the U-shaped pipe 13 to contact the water in the water tank 11, and the toxic gas dissolved in water in the toxic mixed gas is absorbed by the water in the water tank 11, while the toxic gas insoluble in water is absorbed by the water in the water tank 11. The toxic gas is located above the liquid surface. As the amount of water-insoluble toxic gas above the liquid surface increases, the air pressure in the water tank 11 increases. Eventually, the air pressure is greater than the magnetic force between the annular magnet plate 20 and the magnet sealing plate 23, pushing the magnet sealing plate 23 to move upward and separate from the annular magnet plate 20. Under the action of the air pressure, the water-insoluble toxic gas quickly enters the fixed tube 18, and the water vapor mixed with the water-insoluble toxic gas is absorbed by the desiccant 31, so that the water-insoluble toxic gas is in a dry state after passing through the desiccant 31. At the same time, when the water-insoluble toxic gas quickly enters the fixed tube 18, the water-insoluble toxic gas will push the screw 31 to move upward. The propeller 27 rotates, and the rotation of the propeller 27 drives the rotating rod 29 to rotate. The rotation of the rotating rod 29 drives the stirring plate 32 to rotate to stir the desiccant 31, so that each particle of the desiccant 31 has the opportunity to contact with the water vapor in the mixture of the water-insoluble toxic gas, so that the water-insoluble toxic gas can better contact with the desiccant 31, thereby accelerating the drying process. Finally, the water-insoluble toxic gas moves upward and contacts with the activated carbon plate 15, and the water-insoluble toxic gas is absorbed by the activated carbon plate 15, thereby completing the collection and treatment of the toxic gas generated in the electric welding process, so that the workers can work in a comfortable environment, ensuring the physical and mental health of the workers.

[0025] Compared with the related art, the PCB circuit board welding equipment provided by the present invention has the following beneficial effects: The present invention provides a PCB circuit board welding device. The circuit board is first placed on a bottom plate 1 and located below a welding gun head 6. The output shaft of an electric push rod 4 is extended downward to drive the welding gun head 6 to contact the circuit board, thereby completing the welding operation on the circuit board. When toxic mixed gas is generated during the welding process, a suction fan 10 is started to generate suction to transport the toxic gas through an annular tube 8, an air inlet pipe 7, a telescopic corrugated connecting pipe 9, a connecting pipe 12 and a U-shaped pipe 13 to contact with water in a water tank 11. The toxic gas dissolved in water in the toxic mixed gas is absorbed by the water in the water tank 11, while the toxic gas insoluble in water is located above the liquid surface. As the amount of toxic gas insoluble in water above the liquid surface increases, the magnet sealing plate 23 is pushed upward to move to contact with the water in the water tank 11 under the action of air pressure. The annular magnet plate 20 separates and quickly enters the fixed tube 18, and absorbs the water vapor mixed with the water-insoluble toxic gas through the desiccant 31, so that the water-insoluble toxic gas is in a dry state after passing through the desiccant 31. At the same time, when the water-insoluble toxic gas quickly enters the fixed tube 18, the stirring plate 32 rotates to stir the desiccant 31, so that each desiccant 31 particle has the opportunity to contact with the water vapor in the water-insoluble toxic gas mixture, thereby accelerating the drying process. Finally, the water-insoluble toxic gas moves upward and is absorbed by the activated carbon plate 15, thereby completing the collection and treatment of the toxic gas generated during the electric welding process, so that the workers can work in a comfortable environment and ensure the physical and mental health of the workers.

Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
