Description

Technical Field

[0001] The present invention relates to the technical field of electronic component processing equipment, in particular to an automatic machine for processing pins of electronic components. Background Art

[0002] Housings containing electronic components are typically manufactured using a continuous injection molding process (i.e., multiple housings for electronic components are injection-molded onto a single pin substrate). After molding, the multiple housing components are regularly arranged on the pin substrate, and then bending and cutting equipment is used to bend and cut the pins. Traditional bending and cutting equipment has a low degree of automation, and the placement and handling of housing blanks during processing still relies on manual labor. This inefficient bending and cutting of pins consumes labor costs, leading to high production costs for the company. Furthermore, the equipment can easily cause accidental injuries to workers during the placement and handling of materials, resulting in poor safety. Summary of the Invention

[0055] 2. The lifting slide 21 on the feeding mechanism 20 rises to the material taking station 28, and the slide cylinder 271 controls the telescopic baffle 27 to extend to the bottom of the uppermost material tray 14.

[0057] 4.
