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 the attached Figure 1-6 , a processing method of lead-acid battery casting pole plate, its steps are as follows:

[0032] (1) Filling

[0033] Filled with lead paste on the unslit large grid to form a wet plate;

[0034] (2) Lamination

[0035] Double-sided lamination is performed on the surface of the wet electrode plate filled with lead paste (folded 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] Continuously slitting large wet plates after lamination;

[0038] (4) Drying

[0039] Dry the surface of the small wet plate after slitting.

[0040] The described unslitted pole plate grid is in the shape of a square grid, which can be divided into 4 finished pole plates 1 of equal size, and there are concave slitting grooves 2 between the finished pole plates 1, which are used for convenience. Slitting is carried out; pole lugs 3 are respectively provided...

Abstract

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. A method for processing lead-acid battery pouring plates, the steps of which are as follows: (1) filling and coating, filling and coating lead paste on large grids that have not been cut to form wet plates; (2) coating, The surface of the wet electrode plate filled with lead paste is folded in half and coated on both sides (the center line of the film is folded in half, and the film covers the upper surface and the lower surface of the grid at the same time); The plate is continuously cut; (4) Drying, the surface of the small piece of wet plate after cutting is dried. The large uncut grid is a matt grid, and the grid can be cut into 4 finished plates of equal size, and there are concave cutting grooves between the finished plates for convenient Slitting is carried out; tabs are respectively provided at both ends of the grid, and each of the two tabs is connected by poured side strips.

Description

technical field [0001] The invention relates to a method for processing a lead-acid battery for pouring a pole plate, and relates to a method for processing and forming a pole plate in a lead-acid battery. Background technique [0002] At present, in the process of manufacturing the cast plate coating of lead-acid batteries, the large grid is usually filled with lead paste, and then the surface is sprayed with acid, surface dried, cured and dried, so as to produce a large plate. Since this production method requires surface acid drench, and the dried large plates are cut, waste sulfuric acid and lead paste particles will be generated during the cutting process, and the residual lead paste particles will easily lead to battery short circuit and affect the quality. Waste sulfuric acid and lead paste particles can also cause hazardous waste pollution; on the other hand, operating the slicing machine consumes a lot of manpower. All it is necessary to devise a new production met...
