[0002] The stringing machine uses a mechanical transmission mechanism to transport the battery cells, and uses the high-temperature gas of the hot air pipe on the heated bottom plate to weld the battery cells. String welding is to connect the pins of electronic components to the circuit board through solder wires. The waste gas generated during the string welding process mainly comes from the welding process of the solder wire. The solder in the solder wire will melt when heated, and the released volatile organic compounds and solder vapor will form waste gas.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0030] like Figure 1 , Figure 2 As shown, an exhaust gas treatment system for a string welding machine includes a smoke exhaust tower 6, an exhaust fan 5, a purifier 4, an exhaust pipe 8 and a suction head 9. In this embodiment, the exhaust gas generated by the string welding machine 3 during welding is sucked by the suction head 9, and the exhaust gas passes through the exhaust pipe 8, the purifier 4 and the exhaust fan 5 in sequence, and finally the exhaust gas is discharged into the environment through the smoke exhaust tower 6.

[0031] Specifically, the purifier 4 is installed outside the workshop 1, and the purifier 4 is used to purify the exhaust gas. The exhaust fan 5 is also installed outside the workshop 1, and the exhaust fan 5 is connected to the purifier 4, and the exhaust fan 5 is used to extract the exhaust gas purified by the purifier 4. The purifier 4 and the exhaust fan 5 are both existing technologies, and the structure and working principle are not repeated.

[0032] The exhaust pipe 8 is divided into a first pipe section and a second pipe section. The exhaust pipe 8 has an air inlet end and an air outlet end. The air inlet end is located on the first pipe section, and the air outlet end is located on the second pipe section. The first pipe section is located in the workshop 1 and extends into the protective frame 2 of the stringing machine 3. The first pipe section passes through the roof of the workshop 1 and is connected to the second pipe section. The second pipe section is located outside the workshop 1 and extends along the roof of the workshop 1. The second pipe section is connected to the inlet of the purifier 4, that is, the inlet of the purifier 4 is connected to the air outlet end of the exhaust pipe 8.

[0033] The suction head 9 is arranged below the stringer 3 and is connected to the air inlet end of the exhaust pipe 8, that is, the suction head 9 is connected to the first pipe section, so that the exhaust gas generated by the stringer 3 flows downward without passing through the top of the stringer 3.

[0034] In this embodiment, the suction head 9 is arranged below the stringer 3, so that when the exhaust fan 5 extracts the waste gas generated by the stringer 3, the flow direction of the waste gas is downward, and the position of the nasal cavity of the staff is higher than the height of the stringer 3, so the staff cannot inhale the waste gas, thereby ensuring the personal safety of the staff.

[0035] In order for the suction head 9 to absorb the exhaust gas more fully and ensure that there is no exhaust gas residue at the string welding machine 3, the suction head 9 has two suction ports 10, and the two suction ports 10 face different directions. For example, one suction port 10 faces the left, and the other suction port 10 faces the right. At the same time, the number of suction ports 10 can also be determined according to actual needs. For example, the suction head 9 has three suction ports 10, four suction ports 10, five suction ports 10, six suction ports 10, and so on. In this way, by setting the suction ports 10 in different directions, the exhaust gas at the string welding machine 3 can be absorbed in multiple directions.

[0036] Specifically, the smoke exhaust tower 6 is connected to the exhaust fan 5, and the smoke exhaust tower 6 is used to discharge the purified exhaust gas. The smoke exhaust tower 6 is arranged vertically. In order to ensure the stability of the smoke exhaust tower 6, three pull ropes are arranged at equal intervals around the smoke exhaust tower 6. One end of the three pull ropes is connected to the smoke exhaust tower 6, and the other end of the three pull ropes is connected to the ground. By setting pull ropes at three positions around the smoke exhaust tower 6, three-point positioning, the pull ropes pull the smoke exhaust tower 6 to prevent the smoke exhaust tower 6 from tilting, thereby ensuring the stability of the installation of the smoke exhaust tower 6.

[0037] In order to ensure that the top of the smoke exhaust tower 6 can discharge exhaust gas normally on rainy and snowy days, Figure 3 As shown, a plurality of support rods 11 are arranged at equal intervals at the top of the smoke exhaust tower 6, and a protective cover 7 is installed at the top of the plurality of support rods 11. The diameter of the protective cover 7 is larger than the diameter of the top of the smoke exhaust tower 6, and there is a gap between the protective cover 7 and the top of the smoke exhaust tower 6, so that the purified exhaust gas can be discharged from the smoke exhaust tower 6. By arranging the protective cover 7 at the top of the smoke exhaust tower 6, rain and snow can be prevented from falling into the smoke exhaust tower 6, thereby ensuring the normal exhaust of the exhaust gas.

[0038] The working process of this utility model is as follows:

[0039] The suction head 9 is set below the stringer 3, so that when the exhaust fan 5 extracts the exhaust gas generated by the stringer 3, the flow direction of the exhaust gas is downward, and the position of the nasal cavity of the staff is higher than the height of the stringer 3, so the staff cannot absorb the exhaust gas, ensuring the personal safety of the staff. The exhaust gas extracted by the suction head 9 passes through the exhaust pipe 8, the purifier 4 and the exhaust fan 5 in turn, and finally the purified exhaust gas is discharged into the environment through the smoke exhaust tower 6.
