[0019] The utility model will be further explained in connection with the drawings.

[0020] As shown in Figure 1 , Figure 2 An embodiment of the utility model discloses a kind of pole group plate lug pretreatment devices, including residual tank 8, cast flux tank 7 and residual liquid tank 6 connected in sequence, wherein, steel wire brush 2 is equipped in residual tank 8, wet brush 3 and float ball valve 4 are equipped in cast flux tank 7, dry brush 5 is equipped in residual liquid tank 6.

[0021] Steel wire brush 2 is rotatably arranged at opposite sides of the upper part of residue groove 8. Steel wire brush 2 is a thin steel wire brush. The upper end of steel wire brush 2 is higher than the upper end of residue groove 8. The problem of manually brushing the lugs is solved, the surface lead paste and oxide layer is effectively removed, and the production efficiency is improved.

[0022] Wet brush 3 is rotatably arranged at opposite sides of the upper part of casting flux groove 7. The upper end of wet brush 3 is higher than the upper end of casting flux groove 7. Float ball valve 4 is connected to the port of casting flux pipeline 11. Casting flux groove 7 is filled with casting flux. The automatic addition of casting flux is realized, and the removal of excess casting flux is ensured. The problems of not brushing casting flux and not welding lugs due to the lack of timely replenishment of casting flux in the current device, and the problems of too much casting flux on the surface of lugs and poor welding of casting flux pores due to the addition of too much casting flux are solved.

[0023] Dry brush 5 is rotatably arranged at opposite sides of the upper part of residue groove 6. The upper end of dry brush 5 is higher than the upper end of residue groove 6.

[0024] The upper ends of steel wire brush 2, wet brush 3 and dry brush 5 are located on the same horizontal plane and cooperate with the lugs 9 of the pole group 10 passing from above in the movement direction 1.

[0025] The lug pre-treatment is divided into three stages, which effectively ensures the welding quality. The first stage is a thin steel wire brush, which mainly brushes off the lead paste and oxide layer remaining on the surface of the lug 9; the second stage is a wet brush 3, which mainly brushes the casting flux on the surface of the lug 9; the third stage is a dry brush 5, which mainly brushes off the excess casting flux in the form of droplets, leaving only a thin layer of flux on the surface of the lug 9.

[0026] After the excess lead paste is brushed off by steel wire brush 2, it is collected in residue groove 8. The liquid level of casting flux in casting flux groove 7 is controlled by float ball valve 4. When the liquid level is lower than wet brush 3, the float ball descends, float ball valve 4 opens, and the casting flux is automatically added; after a certain liquid level is added, the float ball rises, float ball valve 4 closes, and the addition of casting flux stops. Dry brush 5 brushes off the droplet-shaped casting flux on the lug 9, and residue groove 6 is used to collect excess casting flux.
