Vertical sintering furnace for single-ended glass-sealed thermistor

Abstract

The invention discloses a vertical sintering furnace for a single-ended glass-sealed thermistor. The vertical sintering furnace comprises a conveying belt and a sintering furnace body, the belt face of the conveying belt is horizontally arranged, the sintering furnace body and the conveying belt are correspondingly arranged, a hearth with a downward opening is arranged on the sintering furnace body in the conveying direction of the conveying belt, the conveying belt is used for conveying elements to penetrate through the hearth, the elements vertically penetrate through the hearth on the conveying belt, and the upper ends of the elements are sleeved with glass shells used for glass sealing the upper ends of the elements. According to the vertical sintering furnace for the single-ended glass-sealed thermistor, the structure is stable, the layout is reasonable, the operation is smooth, vertical sintering glass sealing can be carried out on the single end of the element, the sintering glass sealing effect is good, the automation degree is high, the machining efficiency is high, and the quality is good.

Description

technical field [0001] The invention relates to the field of resistance element processing, in particular to a vertical sintering furnace for a single-end glass-sealed thermistor. Background technique [0002] In the sintering furnace for single-ended glass-sealed components currently on the market, when the glass-sealed components are sintered, the components are placed horizontally on the conveyor belt of the sintering furnace. , causing the lower side of the glass bulb to be thicker, the upper side glass to be thinner, and the shape to be asymmetrical; and the same reason, resulting in less and thinner glass adhesion on the upper side of the lead, and relatively more glass adhesion on the other side of the lead. In this way, when the component lead is bent, disassembled, processed or used, the glass bulb at the lead end of the side with less glass adhesion is easy to find that the glass is broken, or even the glass bulb is broken, causing the resistance value of the singl...

[0002] In the sintering furnace for single-ended glass-sealed components currently on the market, when the glass-sealed components are sintered, the components are placed horizontally on the conveyor belt of the sintering furnace. , the lower side of the glass bulb is thicker, the upper side glass is thinner, and the shape is asymmetric; in addition, the glass on the upper lead is less and thinner, and the glass on the other lead is relatively more adhered

In this way, when the component lead is bent, disassembled, processed or used, the glass bulb at the lead end of the side with less glass adhesion is easy to find that the glass is broken, or even the glass bulb is broken, causing the resistance value of the single-ended component to change and the reliability to decrease, and there is a large quality problem.
