Abstract
The invention discloses a hole pricking device for a positive electrode plate of a storage battery. The hole pricking device comprises a bottom plate and a pressure plate which is pressed on the bottom plate; a mold cavity which is the same as the outer contour of a positive grid of the storage battery is formed in the bottom plate; pricking needles are inserted into an area corresponding to each grid of the positive grid on the pressure plate; the needle tips of the pricking needles are downward and are exposed from the back surface of the pressure plate; positioning rods are arranged on the bottom plate; positioning holes for the positioning rods to match and insert are formed in the pressure plate. The hole pricking device for the positive electrode plate of the storage battery is simple in structure and convenient to manufacture; when the hole pricking device is used, the positive electrode plate is placed in the mold cavity of the bottom plate and is positioned; the manufactured pressure plate is inserted into a positioning plate in a manner that the front surface is upward; the pressure plate is pressed down and the pricking needle tips distributed on the back surface of the pressure plate to prick holes; according to the device, materials are easily obtained; the device is easy to manufacture; the pricking needles can be reused repeatedly; all tiny holes can be pricked in the positive electrode plate at one time; the effective action area of active substances on the positive grid is increased, the utilization rate of the active substances on the positive grid and the energy efficiency of the battery are improved.
Description
[0001] technical field [0002] The invention relates to the field of storage battery production, in particular to a device for piercing holes in positive plates of storage batteries. Background technique [0003] The energy efficiency of a storage battery with a certain volume and weight depends largely on the effective area of the active material on the positive plate. The larger the area of action of the active material, the higher the utilization rate of the active material. For this reason, micropores of a certain depth can be pierced on the positive electrode plate during production to achieve the purpose of increasing the effective area of the active material. The positive plate is composed of a net-like positive grid and active material lead paste, and the grid design is diverse. If you want to punch hundreds of needle-like microholes on it, the efficiency of manually punching holes one by one is obviously too low, so The prior art lacks a special device for p...
