AI Technical Summary

Technical Problem

In the existing PCB board drilling process, manual fixing can easily lead to displacement, affecting the accuracy and consistency of the hole positions. Traditional positioning mechanisms are complex and not suitable for PCB boards of different sizes, resulting in low production efficiency and frequent tape replacements, which is costly.

Method used

A slanted groove vertical clamping mechanism for multi-layer thin boards is designed. Synchronous clamping and positioning are achieved through a slanted linkage assembly of the main slider, the secondary slider, and the pressure tongue. Elastic elements are used to provide clamping force and simplify drive control. It is suitable for PCB boards of different sizes.

Benefits of technology

It enables rapid and precise clamping and positioning of PCB boards, improves production cycle time, reduces system complexity and cost, is applicable to all drilling machines on the market, and has strong clamping and positioning reliability and consistency.

Abstract

The application provides a chute type vertical pressing mechanism for multi-layer sheet, which comprises a main sliding block moving in horizontal direction, a sub-sliding block horizontally slidingly connected with the main sliding block and used for abutting against the side surface of the multi-layer sheet, and a tongue pressing the upper surface of the multi-layer sheet and vertically slidingly connected with the sub-sliding block, wherein a chute linkage assembly for mutual cooperation to make the tongue press downward when the sub-sliding block and the main sliding block move towards each other is arranged between the main sliding block and the tongue, the chute linkage assembly comprises a slanting chute arranged on the tongue and a sliding shaft arranged on the main sliding block and slidingly matched with the slanting chute, or the chute linkage assembly comprises a slanting chute arranged on the main sliding block and a sliding shaft arranged on the tongue and slidingly matched with the slanting chute. The main sliding block, the sub-sliding block and the tongue arranged in linkage can be applied to multi-layer sheets of different sizes, realize fast and accurate pressing and positioning of the multi-layer sheet, and effectively improve the production rhythm.
