Description

Technical Field

[0001] This invention relates to the field of thermocouple manufacturing technology, and more particularly to a counter-assembly device for thermocouple manufacturing. Background Technology

[0002] Thermocouples are commonly used temperature-sensing elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium by electrical instruments. Thermocouples are sensors specifically designed to monitor the thermal energy inside high-temperature equipment. Due to their high safety, thermocouples are widely used in special applications such as petroleum refining and chemical reactors. Thermocouples also have advantages such as simple structure, ease of manufacturing, wide measurement range, high accuracy, low inertia, and easy long-distance transmission of output signals.

[0003] In existing thermocouple production and assembly processes, manual operation combined with auxiliary mechanisms is typically employed. First, the installation location of the thermocouple is determined, generally choosing a spot that accurately reflects temperature changes. Then, the thermocouple head is inserted into the connecting terminal. Because an extension cable is required for the connection, and this extension cable lacks an effective traction mechanism, it tends to wobble and become tangled. This leads to poor contact and misalignment during connector assembly, reducing overall assembly efficiency and degrading thermocouple quality. Therefore, we propose a counter-assembly equipment and method for thermocouple production to address the aforementioned problems. Summary of the Invention

[0004] To overcome the problem that during thermocouple assembly, the extension wires used for connection are not equipped with an effective traction mechanism, causing them to sway and become entangled, resulting in poor contact and misalignment during joint assembly, reducing overall assembly efficiency and degrading thermocouple quality, this invention provides a counter-assembly device for thermocouple production.
