Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a cutting device for a thermistor lead wire. Background Art
[0002] Thermistor, also known as negative temperature coefficient thermistor, is a type of thermistor whose resistance decreases as the temperature increases. Using its characteristics, it can be made into a variety of products with applications such as surge suppression, temperature compensation, precision temperature measurement, temperature control, flow detection, etc. It is an electronic component with a wide range of uses.
[0003] In the production process of thermistors, the leads need to be fixed to the thermistor chip. The main function of the leads is thermal isolation to prevent heat from being transferred to the resistor through the wires. It is also convenient for connecting with the main circuit. Generally, the leads are wound on a winding reel. When in use, the tortuous leads wound on the reel need to be straightened and reprocessed. In the process of straightening the leads, manual straightening has been used in the past, which is inefficient and has poor straightening effects. In addition, the straightened leads need to be cut off with other tools, which is inconvenient to operate and has poor applicability. Summary of the invention
[0004] The utility model aims to provide a thermistor lead wire cutting device with strong applicability in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The utility model creatively arranges a workbench, a pressing assembly, an adjusting member, a straightening wheel, a wire-passing platform and a cutting platform. The lead wire enters from one side of the workbench and exits from one side of the wire-passing platform. When the lead wire passes through the workbench, the pressing assembly is first used to press the lead wire downward so that the lead wire is not easily lifted or deviated. Then the lead wire is straightened and adjusted by the straightening wheel. The adjusting member can change the left and right positions of the straightening wheel, thereby adjusting the lead wire so that the lead wire is not easily deviated left and right. Then the lead wire passes through the wire-passing platform and is embedded in a wire-passing groove in the wire-passing platform. The inner diameter of the wire-passing groove matches the lead wire and the wire-passing groove can limit the lead wire, thereby improving the straightening effect of the lead wire. Finally, the lead wire passes through the cutting platform, and the cutting member can cut the lead wire. Two wire-passing platforms are respectively arranged on both sides of the cutting platform so that the straightening state can be guaranteed even when the lead wire is too long, thereby improving the applicability of the device.
