Description

technical field [0001] The invention belongs to the technical field of assembly of electronic components, and in particular relates to a resistance pin cutting and forming device and method. Background technique [0002] At present, the assembly requirements for components on the circuit board are getting higher and higher. Therefore, it is often necessary to cut the pins of the electronic components before the circuit board assembly, so as to ensure that the height of the electronic components from the circuit board is consistent and meets the relevant requirements when the electronic components are inserted. [0003] The purpose of shear forming of component leads is to mechanically deform the leads of components into the expected shape, so as to meet the process requirements in the assembly process of components. For enterprises with a small production volume, the cutting of the pins of electronic components is done manually by workers. Manual cutting has the problems of...
