AI Technical Summary

Technical Problem

Existing chip testing fixtures suffer from problems such as pin insertion operations involving stacking and tangling, incomplete quality inspection, low posture conversion efficiency, and inconvenience in switching between multiple fixtures, which affect the continuity and stability of the insertion process.

Method used

The system integrates a distributed feeding assembly, a needle column picking assembly, an alternating feeding assembly, a needle column insertion assembly, a fixture positioning assembly, and a detection and sorting assembly using a support assembly component. By combining linear vibrators and dual-axis vibrators, it achieves distributed feeding and attitude conversion of the needle columns, and sets up a multi-level detection and sorting mechanism to ensure needle column quality and insertion accuracy.

Benefits of technology

It achieves continuous and stable feeding of needle columns, all-round quality inspection, and automated insertion of multiple fixtures, which improves production efficiency and yield, and reduces labor costs and equipment complexity.

Abstract

The application discloses a needle column plug-in device for a chip testing fixture and a use method thereof, and the device comprises a support assembly, a dispersion feeding assembly, a needle column picking assembly, an alternate feeding assembly, a needle column plug-in assembly, a fixture positioning assembly and a detection sorting assembly. The dispersion feeding assembly adopts a linear vibrator and a double-shaft vibrator to form a two-stage vibration dispersion structure, so that the needle column is in a transverse separation state; the needle column picking assembly adsorbs a radial side of the needle column through a picking suction disc; the alternate feeding assembly is provided with a feeding turntable and a pair of receiving carriers, and realizes attitude switching of transverse deflection and vertical deflection of the needle column; the needle column plug-in assembly adsorbs an axial end of the needle column through a plug-in suction disc and inserts the needle column into the fixture; and the detection sorting assembly is provided with a three-stage detection sorting mechanism and detects and sorts a radial bottom, an axial upper end and an axial lower end of the needle column respectively. The problems of needle column stacking and winding, incomplete quality detection and low attitude conversion efficiency can be solved, and production efficiency and a yield rate are improved.
