The invention discloses a paste-coating method for a punched mesh grid for a lead-acid battery, comprising the following steps: Step 1, a whole lead strip with a certain thickness is punched by a punching machine to form a continuous grid strip; The grid tape is wound into rolls; in step 2, the wound grid tape is placed on the support frame for unwinding, and then the unrolled grid tape is horizontally transported to the paste applicator, and the grid tape is drawn out. Place the support frame of the grid belt to the part between the paste applicator, cover the upper and lower surfaces of the grid belt with sodium hydroxide solution, so that a thin layer of sodium hydroxide aqueous solution is formed on the surface of the grid belt, and then cover the upper and lower surfaces with sodium hydroxide solution The grid belt is conveyed to the paste applicator to apply lead paste; step 3, the grid belt that has been coated with lead paste is cut, collected and cured to form a single-piece grid. The invention significantly enhances the bonding force between the grid of the electrode plate and the lead paste. |
