Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention discloses an automatic electric welding device for a battery pack, including an electric welding device 1 and a gas treatment device 2. The electric welding device 1 includes a protective box body 101. An internal processing cavity 102 is opened in the protective box body 101. A protective box door 103 is hinged at the opening of the processing cavity 102. A placing seat 104 and an electric welding machine head 105 are arranged on the inner wall of the processing cavity 102. A touch switch 106, an alarm 107 and a status display lamp 108 are arranged on the front side of the protective box body 101. An external handle 109 is arranged at the top of the protective box body 101. A guide fan 110 is arranged at the side end of the protective box body 101;

[0022] The gas treatment device 2 includes a treatment box 201. The treatment box 201 is located outside the guide fan 110. Three filter screens 204 are movably inserted into the treatment box 201. A partition board 206 is fixedly installed on the inner wall of the treatment box 201. A water accumulation box 209 is placed inside the treatment box 201. The inner side of the partition board 206 is movably connected to an air pipe 208 through a gas guide block 207. The air pipe 208 is located below the liquid level of the water accumulation box 209;

[0023] A movable cover 202 is movably installed at one end of the treatment box 201 away from the guide fan 110. A water tank 210 is fixedly installed at the top of the movable cover 202. An atomizing nozzle 211 is fixedly installed at the bottom of the water tank 210. The atomizing nozzle 211 is located inside the movable cover 202. The atomizing nozzle 211 is above the water accumulation box 209.

[0024] By setting up the gas treatment device 2, the processing waste gas input by the guiding fan 110 can be purified step by step by using three groups of filter nets 204. Then, in cooperation with the gas guiding block and the air pipe 208, the waste gas after primary purification can be introduced into the water accumulation box 209 for water washing treatment, and the atomizing nozzle 211 can spray the water in the water tank 210 in the form of mist and conduct dust reduction treatment with the waste gas after water washing, so that the processing waste gas is harmlessly discharged after being treated by three processes, thus realizing the gas purification of the processing waste gas and further ensuring the air quality of the surrounding environment.

[0025] Specifically, a socket 203 is fixedly installed on the inner wall of the treatment box 201. The bottom end of the filter net 204 is located inside the socket 203, and the top end of the filter net 204 extends above the socket 203 and is fixedly installed with a lifting handle 205.

[0026] In this implementation scheme, by inserting the bottom end of the filter net 204 into the socket 203 and cooperating with the lifting handle 205, the filter net 204 can be quickly taken out, thus facilitating the staff to replace the filter net 204.

[0027] Specifically, an air outlet is provided at the side end of the movable cover 202, and a dust-proof net 212 is arranged on the inner wall of the air outlet.

[0028] In this implementation scheme, the dust-proof net 212 can prevent external impurities from entering the interior of the treatment box 201 through the movable cover 202.

[0029] Specifically, a placement opening is provided at the bottom end of the treatment box 201, and the water accumulation box 209 is located inside the placement opening.

[0030] In this implementation scheme, the placement opening can facilitate the removal of the water accumulation box 209 from the interior of the treatment box 201.

[0031] During use, open the protective box door 103, place the battery pack on the placement seat 104, then close the protective box body 101, and then start the welding machine head 105 through the touch switch 106, prompting the welding machine head 105 to start processing other workpieces such as the battery pack;

[0032] The above working principle has been proposed in a battery pack automatic welding machine with a protection component with the patent publication number CN219457710U;

[0033] When it is necessary to purify the waste gas generated during the processing, start the guiding fan 110, prompting the waste gas to enter the treatment box 201 driven by the guiding fan 110, and the waste gas sequentially passes through three filter nets 204 for step-by-step filtration, so that the impurities in the gas are filtered and adsorbed;

[0034] Subsequently, the waste gas passes through the gas guide block 207 and the air pipe 208 and immerses below the liquid level of the water accumulation box 209 to undergo a water washing reaction, so that the impurities in the waste gas are purified again. Subsequently, the gas will float out from the water body of the water accumulation box 209;

[0035] Then start the atomizing nozzle 211, so that the atomizing nozzle 211 sprays the water in the water tank 210 in the form of mist and finally contacts the waste gas for the third purification, so that the impurities in the waste gas are wetted by the water droplets and fall into the water accumulation box 209. Subsequently, the waste gas after three treatments is discharged outward through the dust-proof net 212;

[0036] When it is necessary to replace the water in the water accumulation box 209, remove the movable cover 202, and then pull out the water accumulation box 209.

[0037] In summary, for this automatic electric welding device for battery packs, by setting the gas treatment device 2, the three groups of filter nets 204 can gradually purify the processing waste gas input by the guiding fan 110. Cooperating with the gas guide block and the air pipe 208, the waste gas after the initial purification can be introduced into the water accumulation box 209 for water washing treatment, and the atomizing nozzle 211 can spray the water in the water tank 210 in the form of mist and perform dust reduction treatment on the waste gas after water washing, so that the processing waste gas is harmlessly discharged after three processes of treatment, thereby realizing the gas purification of the processing waste gas and further ensuring the air quality of the surrounding environment.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
