Description

technical field [0001] The invention relates to the technical field of electronic product processing, in particular to an automatic pin grinding method and a grinding machine. Background technique [0002] The pins of electronic products such as earphone pins in the prior art are more commonly used, and the output is larger, and the models are also more. The usual earphone pin is a 3.5mm four-level pin, including four metal parts coaxially sleeved in sequence and an insulating layer for isolating the four metal parts from each other. Four welding pads are formed on the rear end for connecting with the earphone core wire. The four welding pads are arranged to form a welding part. The length of the welding part is 3.4-4.6mm, and the total length of the earphone pin is 17.4- 18.8mm. Generally, welding parts, punching parts, etc. are designed. After the initial processing, the surface of the product has uneven defects and needs to be further polished. [0003] The traditional...

Problems solved by technology

[0003] The traditional grinding process of electrical connection pins for electronic products is mostly manual grinding, which is inefficient and has great instability, resulting in uneven grinding quality of the pins

Even if the corresponding auxiliary equipment is used in the pin grinding process, it can only achieve semi-automation at most, with high manual dependence, which is not conducive to mass production, and is not conducive to the stable control of product quality
