[0002] In the production and manufacturing process of electronic components, the pins of electronic components often need to be bent to meet the subsequent circuit board assembly process requirements. Traditional pin bending operations mostly rely on manual feeding, and workers need to manually place electronic components one by one into the processing position of the bending equipment. This way not only has extremely low efficiency, but also is difficult to meet the needs of modern mass production, and long-term repetitive work can easily make workers tired, leading to an increase in feeding error rate and affecting product quality.

[0003] With the development of automation technology, some semi-automatic or fully-automatic feeding mechanisms have emerged. However, the existing feeding mechanisms still have many shortcomings. When feeding, the processed electronic components need to be sent into the feeding equipment. Due to the presence of pins, and the accumulation of a large number of electronic components in the feeding equipment, the electronic components need to vibrate in the feeding equipment, which can cause damage to some electronic components.

The chip pin bending equipment includes a storage mechanism, a bending mechanism, a positioning mechanism, and a conveying mechanism. The conveying mechanism includes an adsorption assembly and a transmission assembly. The adsorption assembly includes an adsorption member that tightens or loosens the chip. The transmission assembly is adjacent to the storage mechanism, the bending mechanism, and the positioning mechanism, and drives the adsorption assembly to reciprocate along the arrangement direction of the three mechanisms. After the adsorption assembly places the chip on the positioning mechanism, the positioning mechanism and the adsorption end form an abutment to align the center of the adsorption end with the center of the adsorption member above the positioning mechanism.
