Problems solved by technology

Since this production method requires acid leaching on the surface and slitting of large plates after drying, waste sulfuric acid and lead paste particles will be generated during the slitting process. Waste sulfuric acid and lead paste particles will also cause hazardous waste pollution; on the other hand, operating the slicing machine consumes a lot of manpower

Embodiment Construction

[0031] Refer to attached Figure 1-6 , a kind of processing method of lead-acid accumulator casting polar plate, its step is as follows:

[0032] (1) Filling

[0033] Fill and smear lead paste on the uncut large grid to form a wet plate;

[0034] (2) Lamination

[0035] Double-fold double-sided coating on the surface of the wet plate filled with lead paste (fold in half at the center line of the film, and the film covers the upper and lower surfaces of the grid at the same time);

[0036] (3) Slitting

[0037] Continuous cutting of large pieces of wet plates after coating;

[0038] (4) dry

[0039] Dry the surface of the cut small piece of wet plate.

[0040] The uncut pole plate grid is in the shape of matts, and can be cut into four finished pole plates 1 of equal size. There are concave slitting grooves 2 between the finished pole plates 1 for convenience. Carry out slitting; tabs 3 are respectively provided at both ends of both sides of the blank plate, and each of ...

Abstract

The invention discloses a processing method of a cast polar plate of a lead-acid storage battery, and relates to a processing and forming method of a polar plate in a lead-acid storage battery. The processing method of a cast polar plate of a lead-acid storage battery comprises the following steps of: (1) filling and coating: filling and coating a large grid, which is not slit, with lead plaster to form a wet polar plate; (2) film coating: performing folding double-sided film coating on the surface of the wet polar plate filled with the lead plaster (folding is conducted based on the center line of a film, and the film covers the upper surface and the lower surface of the grid at the same time); (3) slitting: continuously slitting the large wet polar plate coated with the film; and (4) drying: drying the surfaces of the slit small wet polar plates. The large grid which is not slit is a grid shaped like a Chinese character 'tian', the grid can be slit into four finished polar plates with the same size, and inwards-concave slitting grooves are formed between the finished pole plates and used for facilitating slitting. Tabs are arranged at the two ends of the two sides of the grid respectively, and each two tabs are connected through a poured edge strip.

Description

technical field [0001] The invention relates to a processing method for pouring polar plates of lead-acid batteries, which relates to a processing and forming method for the polar plates of lead-acid batteries. Background technique [0002] At present, in the process of manufacturing cast plate coatings for lead-acid batteries, the large grids are usually filled with lead paste, and then the surface is soaked with acid, the surface is dried, and cured to dry, thereby producing large plates. Since this production method requires acid leaching on the surface and slitting of large plates after drying, waste sulfuric acid and lead paste particles will be generated during the slitting process. Waste sulfuric acid and lead paste particles will also cause hazardous waste pollution; on the other hand, operating the slicing machine consumes a lot of manpower. So it is necessary to design a new production method to meet the actual demand. Contents of the invention [0003] In view...
