Slag removing machine for PCBhole

Abstract

The invention discloses a slag removing machine for a PCB hole. The slag removing machine for the PCB hole comprises a base, a door frame, an air cylinder, guide rods, an upper bearing plate, a lower bearing plate, a speed regulating motor, an air box, a clamping head, a pre-pressing drilling tool mechanism, a cross laser, a Y axis feeding mechanism, an X axis feeding mechanism, a controller, a marking block with a cross-shaped marking groove and a placing mold, wherein the guide rods are symmetrically arranged along the air cylinder; a PCB needing to be subjected to slag removing is placed in the placing mold, the controller controls the air cylinder to push the upper bearing plate to move down, thereby pushing the pre-pressing drilling tool mechanism to move down to compress the PCB tightly, the speed adjusting motor works to drive the drilling tool mechanism to extend out slowly, and a tool bit arranged on the drilling tool mechanism smashes and removes the slag adhered to the interior of the hole. The slag removing machine is simple in structure, and can effectively remove the slag and dust adhered to the inner wall of the PCB hole, environmental protection is achieved, the dissociative waste slag can be collected to prevent secondary adhesion of the waste slag, and simultaneously pre-pressing can automatically carried out, so that the hole wall is prevented from being damaged due to deformation of the PCB, and the yield of the PCB is improved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a PCB hole slag remover. Background technique [0002] Printed circuit board, also known as PCB board, is the support body of electronic components and the carrier of electrical connection of electronic components.

[0002] Printed circuit board, also known as PCB board, is the support body of electronic components and the carrier of electrical connection of electronic components. The manufacturing process of PCB board is complicated. The general process is: cutting, drilling, electroless copper (PTH) And electroplating copper, pattern transfer (line), pattern electroplating (second copper) and protective tin plating, etching (SES), intermediate inspection, solder mask (SolderMask), printing characters, metal surface treatment, finished product molding, electrical testing, appearance Inspection (FQC / OQA), packaging and shipment, after the PCB board is drilled, there is a certain probability that glue residue will adhere to the PCB hole. Therefore, the PCB board needs to be desmeared before copper sinking. The PCB board is soaked in the medicine tank to remove the scum. Not only does it take a long time to react, but it also requires repeated desmear operations to completely remove the scum, which is inefficient. You can also remove the scum manually, but the efficiency is also relatively low.
