Embodiment
[0032] Such as figure 1 , 2 As shown, a method for preparing a safety electrode of a power battery ceramic sealing ring provided by the present invention includes the following steps:
[0033] Step (1): According to the size of the step surface 3 of the ceramic seal ring groove, a ring pattern 5 is made on the steel plate 4, wherein the outer diameter of the ring pattern 5 is smaller than the outer diameter of the ceramic seal ring groove step surface 3 by 0.5 mm, the ring pattern The inner diameter of 5 is greater than the inner diameter of the stepped surface 3 of the ceramic seal ring groove by 0.5 mm, and the depth of the ring pattern 5 on the steel plate 4 is 0.15 mm.
[0034] Explain with specific data: the outer diameter b of the stepped surface 3 of the ceramic seal ring groove is 20 mm, and the inner diameter a of the stepped surface 3 of the ceramic seal ring groove is 14mm, so the outer diameter of the ring pattern 5 is 19.5 mm, and the ring pattern 5 The inner diameter ...

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 particularly relates to a method for preparing a power battery ceramic sealing ring safety electrode. Background technique [0002] For the step surface of the existing ceramic seal ring groove, there is no special grinding equipment for the time being, and the flatness of the step surface cannot be guaranteed. When the molybdenum-manganese layer is printed, the method of brush coating paste is generally used, which causes the thickness of the molybdenum-manganese paste to vary. As a result, the thickness of the molybdenum-manganese layer on the step surface of the ceramic seal ring groove is different, which affects the air tightness and tensile performance of the subsequent package, and the efficiency is also low. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for preparing a power battery ceram...
