Description

PTC potsherd spraying aluminum support plate

Technical Field

The utility model belongs to the technical field of electronic ceramic material makes, especially relate to a PTC potsherd spouts aluminum support plate.

Background

During the production process of the PTC thermistor ceramic upper electrode, double-sided aluminum spraying is required. In the double-sided aluminum plating operation of the PTC thermistor ceramic, the PTC thermistor ceramic is carried in a carrier so as to be carried out with high quality and high efficiency. The existing PTC thermistor ceramic aluminum-sprayed carrier plate consists of a pore plate and two holding plates, wherein the pore plate is provided with a plurality of carrying holes which are used for loading PTC thermistor ceramic and have the same size as the PTC thermistor ceramic to be loaded, and the holding plates are provided with through holes which have the size slightly smaller than that of the PTC thermistor ceramic to be loaded and have the same number as the carrying holes. When the PTC thermistor ceramic is loaded, the orifice plate is placed on one of the holding plates, the PTC thermistor ceramic is loaded in the loading hole of the orifice plate, and then the other holding plate is covered and fixed by screws. The aluminum-sprayed carrier plate with the structure is troublesome to load and fix, and is inaccurate in positioning. One holding plate and the pore plate are positioned in advance by welding, then loading is carried out, and the other holding plate is covered and fixed by screws. Although the aluminum-sprayed carrier plate is convenient to load, the problem of inaccurate positioning still exists. The consequence of inaccurate positioning is that the quality of sprayed aluminum is directly affected, so that the periphery of the PTC thermistor ceramic is sprayed with an aluminum layer and often needs to be removed through local cleaning. Therefore, the existing aluminum spraying carrier plate is not only troublesome in loading process, but also affects the aluminum spraying quality.
