Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple production, in particular to a device for packaging finished products of platinum-rhodium wire thermocouples. Background Art

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectromotive force signal, which is then converted into the temperature of the measured medium through an electrical instrument (secondary instrument). The appearance of various thermocouples often varies greatly depending on the needs, but their basic structure is roughly the same. They usually consist of main parts such as the thermode, insulating sleeve protection tube and junction box. They are usually used in conjunction with display instruments, recording instruments and electronic regulators. In industrial production processes, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, thermocouples are extremely widely used. They have many advantages such as simple structure, easy manufacturing, wide measurement range, high accuracy, low inertia and easy remote transmission of output signals. Therefore, they are widely used.

[0003] In addition, since the thermocouple is a passive sensor, it does not require an external power supply for measurement and is very convenient to use. Therefore, it is often used to measure the temperature of gas or liquid in furnaces and pipelines and the surface temperature of solids. In the production process of thermocouples, the final molding of the thermocouple is cast in a grid tray, and then the formed thermocouple is placed in the grid tray. When the thermocouple is packaged, the grid trays are removed from the cart one by one, and the thermocouples placed on the grid trays are dumped into the packaging bag, and then packaged. However, since the grid trays need to be manually removed and dumped, the thermocouples are often easy to fall off, and the manual method further reduces the production efficiency. For this reason, we propose a finished product packaging equipment for platinum-rhodium wire thermocouples. Utility Model Content
