Double-face automatic printing method for lithium ion power battery ceramic sealing rings

Abstract

The invention discloses a double-face automatic printing method for lithium ion power battery ceramic sealing rings. The method comprises the following steps that firstly, the ceramic sealing rings are conveyed to a pressure bearing clamp plate, a pressing plate downwards applies pressure, and the front faces of the ceramic sealing rings are located on the same horizontal plane; secondly, the pressure bearing clamp plate and a positioning fixing plate are conveyed to a silk screen printing panel through a belt; thirdly, ink returning on the upper surface of a halftone is conducted; fourthly, ink returning on the lower surface of the halftone is conducted; fifthly, the halftone is moved to the position above the front faces of the ceramic sealing rings, a printing scraper moves to scrap molybdenum manganese pulp on the halftone to the front faces of the ceramic sealing rings in a printing manner, and then drying is conducted; sixthly, the ceramic sealing rings, the pressure bearing clamp plate and the positioning fixing plate are overturned by 180 degrees together, the pressing plate downwards applies pressure, and the back faces of the ceramic sealing rings are flattened to be located on the same horizontal plane; and seventhly, molybdenum manganese printing on the back faces of the ceramic sealing rings is finished, and drying is conducted. According to the double-face automatic printing method, the work efficiency is high, and the consistency of the molybdenum manganese printing thickness of the ceramic sealing rings is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of special silk brushes, and in particular relates to a double-sided automatic printing method for a ceramic sealing ring of a lithium ion power battery. Background technique [0002] When printing the metallized molybdenum-manganese of the existing ceramic seal rings, glue on the glass is used to stick the ceramic seal rings and then dry. The surface of the sealing ring is brushed flat on the surface of the screen with a brush, and the molybdenum-manganese slurry is leak-printed from the screen to the surface of the ceramic sealing ring. This method has the difficulty of controlling the thickness of the glue, which leads to inconsistent adhesion strength with the ceramic sealing ring, and the ceramic sealing ring sticks to the board. At the same time, too much glue will directly affect the quality of the ceramic sealing ring after metallization and sintering. In addition, it is time-consuming and labor-inte...

This method has the difficulty of controlling the thickness of the glue, which leads to inconsistent adhesion strength with the ceramic sealing ring, and the ceramic sealing ring sticks to the board. At the same time, too much glue will directly affect the quality of the ceramic sealing ring after metallization and sintering. In addition, it is time-consuming and labor-intensive. , manual scraping of molybdenum-manganese slurry is difficult to grasp the thickness, which directly affects the printing thickness of the metallized molybdenum-manganese ceramic sealing ring, resulting in affecting the metal welding strength of the ceramic sealing ring
