[0002] A thermistor is a sensor resistor whose resistance value changes with temperature. It is often used as an electronic circuit component for instrument circuit temperature compensation and thermocouple cold end temperature compensation. Some thermistors need to be welded before use, so thermistor chip welding equipment is required.

[0003] For example, the utility model with application number 202322687867.6 discloses a welding device for a thermistor chip. Through the cooperation between a bidirectional screw and a screw sleeve and between a guide plate and a guide rod, two clamping plates are brought close to each other to fix the thermistor chip. Through the cooperation between a motor 1, a transmission shaft and a support shaft, the mounting frame can be rotated. Through the cooperation between a limit plate and an arc rod, the stability of the rotation of the mounting frame is ensured, thereby facilitating the welding of both sides of the thermistor chip.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of thermistor chip welding equipment is convenient for welding both sides of the thermistor chip, but its adjustment method is limited. It can only limit the two sides of the thermistor chip. It can fix thermistor chips of different sizes, but cannot limit thermistor chips of different thicknesses. During the welding process, the thermistor chip may shake up and down or cause wear of the thermistor chip.

[0006] Therefore, a thermistor chip welding device is designed to optimize the above problems. Utility Model Content
