AI Technical Summary

Technical Problem

In the current process of manufacturing copper-embedded substrates for integrated circuits, the tightening and placement of screws are cumbersome and time-consuming, and they are prone to slippage, resulting in low manufacturing efficiency. Furthermore, frequent tool changes are required, making it difficult to adapt to different substrate specifications.

Method used

The dual positioning frame design, combined with electric cylinder drive and automated process, enables parallel operation of screw pre-installation and final tightening. The cooperation of guide plate and limit ring ensures that the screw is inserted and tightened vertically. It is compatible with adjustment components of different sized base plates, simplifies the operation process and reduces inventory costs.

Benefits of technology

It improves manufacturing efficiency, reduces the risk of screw slippage, simplifies operational skill requirements, adapts to various substrate specifications, reduces fixture inventory costs and new product preparation cycles, and ensures continuous operation of the production line and process flexibility.

Abstract

This invention discloses an auxiliary fixture for manufacturing copper-embedded substrates for integrated circuits, relating to the field of printed circuit assembly technology. It includes a base and a switching assembly. A limiting frame is mounted at one top end of the base, and a circuit board assembly is disposed inside the limiting frame. A screw box is located at the other top end of the base. The switching assembly is positioned at the center of the top of the base and includes an electric cylinder. A drive seat is fixed to the output end of the electric cylinder, and sliding columns are symmetrically arranged on the inner side of the drive seat. This invention uses a dual positioning frame to form two independent workstations, allowing one operator to pre-install screws while another operator performs final tightening at the other workstation. This enables parallel operation of pre-installation and final tightening, eliminating the time spent frequently changing tools at a single workstation, ensuring seamless assembly flow, significantly improving overall efficiency. Furthermore, screws accidentally slipping from the operator's hand can be collected in the screw box below, avoiding time-consuming searches.
