Cutting machine for high-precision PTC (Positive Temperature Coefficient) thermosensitive resistor

Abstract

The invention discloses a high-precision PTC (Positive Temperature Coefficient) thermistor cutting machine which comprises a rack and a cutting working device mounted above the rack, the cutting working device comprises a box body welded with the rack, a mounting frame mounted in the box body, and a feeding vibration disc fixed on one side of the box body, the cutting device comprises a box body, a mounting frame fixed to the box body, a pushing mechanism fixed to the mounting frame, a cutting mechanism fixed to the mounting frame and matched with the pushing mechanism, and a touch screen controller mounted outside the box body and used for controlling the cutting device. According to the cutting machine, the steps of automatic feeding, automatic material arrangement and automatic cutting are achieved through mutual cooperation of the feeding vibration disc, the material pushing mechanism and the cutting mechanism, meanwhile, the PTC thermistors can be arranged in order through cooperation of the material pushing mechanism and the cutting mechanism, the cutting progress can be improved, and the cutting efficiency is improved. And meanwhile, the cutting mechanism can be adjusted according to the specifications of the PTC thermistors, and arrangement and cutting of products of different models are achieved.

Description

technical field [0001] The invention relates to the field of electronic component PTC thermistor manufacturing, in particular to a high-precision PTC thermistor cutting machine. Background technique [0002] Because PTC thermistor will form a constant temperature under the action of rated voltage, it is widely used in various heating devices, such as heaters, hair straighteners, air conditioners, and mosquito repellents. For mosquito repellents, the heating power of the PTC thermistor is very important for the volatilization amount and volatilization time of the potion and tablets, so how to ensure the heating power of the PTC thermistor used in the mosquito repellent becomes the main factor in the production of this type of key to the product. [0003] The existing traditional dry pressing molding process will cause the product resistance value to be scattered and the surface temperature to deviate greatly. Therefore, the production process of forming large square pieces a...

Problems solved by technology

[0003] The existing traditional dry pressing molding process will cause the product resistance value to disperse and the surface temperature to deviate greatly. Therefore, the production process of forming a large square piece after firing the electrode and then cutting it into small square pieces has become the mainstream of the production of this type of product.

Due to the small size of the PTC thermistor in the existing cutting machine, it needs to be manually arranged and adjusted during the cutting process, and the cutting efficiency and cutting accuracy are low. Moreover, although the existing cutting machine can cut PTC thermistors of different specifications Sensitive resistors, but all based on manual operation, its cumbersome process and low production efficiency, and it is also prone to the problem of product damage due to large cutting errors
