The battery 5 can be arranged below the reference plate 402, and the position of the battery 5 can be adjusted based on the reference plate 402, so that the liquid injection hole 501 on the battery 5 is aligned with the mounting hole 4021 on the reference plate 402, and the laser emitted by the laser 1 passes through the mounting hole 4021 and hits the wall of the liquid injection hole 501 on the battery 5, so that the residual electrolyte on the wall of the liquid injection hole 501 is removed by laser processing, and the electrolyte is prevented from crystallizing for a long time and affecting the subsequent installation and plugging of the liquid injection hole 501 on the battery 5.

[0020] When the laser processes the residual electrolyte, smoke and waste gas are generated. In order to achieve better cleaning effect, reduce the influence of smoke and waste gas on the respiratory tract safety of personnel, and avoid the influence of smoke and waste gas on the plugging effect of the subsequent plugging nail or the entry of the battery 5 to cause the short circuit of the battery 5, the waste gas collecting ball 3 is arranged on the mounting hole 4021 on the upper side of the reference plate 402.

[0021] The waste gas collecting ball 3 has a cavity, and two laser holes 301 are symmetrically arranged on the waste gas collecting ball 3. When the waste gas collecting ball 3 is arranged in the mounting hole 4021, one of the two laser holes 301 is arranged in the mounting hole 4021 and communicates with the mounting hole 4021, and the other laser hole 301 also communicates with the mounting hole 4021, so that the laser emitted by the laser 1 passes through the two laser holes 301 and the mounting hole 4021 and hits the wall of the liquid injection hole 501 to process the residual electrolyte.

[0022] The waste gas collecting ball 3 can form a spherical converging cavity, and the smoke and waste gas generated after the laser processes the residual electrolyte are collected in the spherical converging cavity through the mounting hole 4021. The waste gas collecting ball 3 is connected with the negative pressure fan through the waste gas exhaust pipe 2, so that the smoke and waste gas collected in the spherical converging cavity are exhausted through the waste gas exhaust pipe 2 by the negative pressure generated by the negative pressure fan.
