Preparation method for safety electrode of ceramic sealing ring of power battery

Abstract

The invention discloses a preparation method for a safety electrode of a ceramic sealing ring of a power battery. The preparation method includes the following steps that (1) a ring-shaped pattern is manufactured on a steel plate; (2) the ring-shaped pattern is subjected to the procedures of film making, plate burning, corrosion, cleaning and polishing in sequence; (3) a matched silicone printing pad is manufactured; (4) a ceramic sealing ring positioning clamp is manufactured; (5) the ceramic sealing ring positioning clamp is sleeved with the ceramic sealing ring, a transfer printing power switch is pressed down, and the ring-shaped pattern on the steel plate is filled with molybdenum-manganese slurry under the action of a covering blade and a scraping blade of a transfer printing machine; and (6) the matched silicone printing pad is pressed downwards until the molybdenum-manganese slurry in the ring-shaped pattern is bonded on the matched silicone printing pad, and the molybdenum-manganese slurry bonded on the matched silicone printing pad is transferred onto a ceramic sealing ring groove step surface. By means of the preparation method, the problems that ink brushes are used for coating ceramic sealing ring groove step surfaces with molybdenum-manganese slurry at present, consequently, working efficiency is low, molybdenum-manganese layers of ceramic sealing ring groove step surfaces are not uniform in thickness, and packaging air tightness is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of special printing, and in particular relates to a method for preparing a safety electrode of a power battery ceramic sealing ring. Background technique [0002] There is currently no special grinding equipment for the step surface of the groove of the existing ceramic sealing ring, and the flatness of the step surface cannot be guaranteed. When printing the molybdenum-manganese layer, the brush is generally used to coat the slurry, resulting in different thicknesses of the molybdenum-manganese slurry. As a result, the thickness of the molybdenum-manganese layer on the step surface of the groove of the ceramic sealing ring varies, which affects the airtightness and tensile performance of subsequent packaging, and at the same time, the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a preparation method ...
