Description

Technical Field

[0001] The present application relates to the technical field of connector assembly, and in particular to a DP automated assembly device. Background Art

[0002] 1. DP connector usually refers to DisplayPort connector, which is a digital display interface standard mainly used to transmit video and audio signals between video sources and display devices. It also supports USB and other forms of data transmission. The three core structural components that constitute the physical connection and electrical functions of the DP connector include a plastic base, pins, and a shielding shell. The plastic base serves as the core skeleton, fixing the pins in their preset holes. The plastic base, together with the pins embedded in it, are nested in the shielding shell. The shielding shell wraps around the main part of the plastic base to provide protection and shielding. Among them, the shielding shell includes a front shell and a back shell. The back shell is provided with a stamped pin positioning groove. The number and spacing of the pin positioning grooves correspond to the pin array to ensure that each pin is accurately aligned after insertion.

[0003] When pins are cut and formed using metal stamping dies, excessive die clearance, blade wear, or misalignment can result in incomplete shearing of the material, forming burrs on the cut edges. As core conductive components, burrs on the pins' surfaces can easily lead to poor connections, signal interference, and other issues. Existing technologies often rely on manual deburring or simple mechanical treatments, which are inefficient, inconsistent, and prone to product failures due to residual burrs. While currently used, automated assembly equipment cannot accurately remove burrs during the DP connector assembly process, resulting in inconsistent assembly quality and reduced yield.
