Double-layer circuit board processing engraving machine based on packaging inner expansion clamping turning

Abstract

The invention discloses a double-layer circuit board processing engraving machine based on packaging inner expansion clamping turning. The structure comprises a machine base, a disposing central column, a clamping turning device, a lateral moving shaft, a front and rear moving bracket and an engraving host. The engraving machine is advantaged in that through an annular airbag clamping mechanism provided, circular or rectangular circuit boards of different shapes and sizes can be clamped through expansion of an airbag, as materials are relatively soft, damage to the circuit boards is avoided; through the telescopic turning mechanism, after one-sided engraving of the circuit board is finished, through pushing a rectangular turning frame forward away from an upper portion of the machine base,turning a front portion of the machine base and then returning to the original position, turning of the circuit board is easily completed, secondary clamping due to turning is not needed, position deviation of the circuit board because of double-sided engraving is prevented, and engraving quality is guaranteed.

Description

technical field [0001] The invention relates to the field of circuit board production and processing, and more specifically relates to a double-layer circuit board processing engraving machine based on wrapping, expanding, clamping and turning over. Background technique [0002] Circuit boards mainly include single-sided circuit boards, double-sided circuit boards and multi-sided circuit boards, but single-sided circuit boards cannot be applied to more complex products, so at present, double-sided circuit boards and multi-sided circuit boards are widely used. However, the existing engraving machine for double-layer circuit board processing has the following defects: [0003] 1. During the engraving process, relatively hard objects such as clips or pressure plates are mainly used to clamp the circuit board. For stable clamping, the clamping force or pressure is large, which may leave traces or even break on the circuit board. , and the shape of the circuit board it clamps is...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an engraving machine for processing double-layer circuit boards based on wrapping inner expansion, clamping and turning over, so as to solve the problem of the engraving machine for processing double-layer circuit boards in the prior art. Among them, relatively hard objects such as clips or pressure plates are mainly used to clamp the circuit board. The shape of the circuit board is limited to a certain extent; when one side of the circuit board is engraved and the other side is to be engraved, it is usually manually turned over, and it needs to be clamped and fixed again, which is troublesome and time-consuming.
