Technical Field
[0001] The utility model relates to the technical field of electronic component production, in particular to a thermistor feeding and molding device. Background Art
[0002] Thermistor is a sensor resistor whose resistance value changes with the change of temperature. The typical characteristic of thermistor is that it is sensitive to temperature and shows different resistance values at different temperatures. According to the different temperature coefficients, it is divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The higher the temperature, the greater the resistance value of the positive temperature coefficient thermistor (PTC), and the higher the temperature, the lower the resistance value of the negative temperature coefficient thermistor (NTC). The working principle of thermistor is to use sensors to help adjust the temperature. Its functions include voltage regulation, volume control, time delay and circuit protection. Thermistor has the functions of temperature measurement, temperature compensation, overheating protection and liquid level measurement. After thermistor is produced, its terminals are generally straight. If the user has different requirements for the terminals of the thermistor, the manufacturer needs to shape or cut the terminals of the thermistor according to the user's requirements to meet the specific requirements of the product.
[0003] When the existing thermistor feeding and forming device is used, a cutting knife is usually used to cut the thermistor feeding. However, since the thermistor feeding has a certain adhesion, this will cause the material to adhere to the cutting knife during the cutting process, thereby affecting the cutting quality and cutting accuracy of the cutting knife. For this reason, we propose a thermistor feeding and forming device. Utility Model Content
