Problems solved by technology

[0004] The above-mentioned method of using positioning pins to correct the level of the substrate, when the substrate is placed on the bed, is likely to produce a gap error between the positioning pin and the clamping groove, which will affect the level of the substrate, resulting in the problem that the drilling machine cannot drill holes accurately At the same time, the above-mentioned method of using the positioning column to cooperate with the tool table to correct the alignment of the substrate also has the problem of gap error between the positioning column of the tool table and the clamping groove, and also has the positioning of the positioning column of the substrate and the tool table. There is a gap error problem between the holes, so it needs to be improved urgently

Abstract

The invention relates to a drill aligning method of a printed circuit board, which comprises a substrate that comprises at least three target points which is positioned by a machine bed; a visual imaging machine arranged above the machine bed is used for reading each target point on the substrate; a target point benchmark value loaded in the visual imaging machine is used for comparison to calculate and obtain an error value; meanwhile, the machine bed or a drilling machine arranged above the machine bed is driven to compensate displacement according to the error value so as to adjust the quasi-position between the drilling machine and the substrate to drill according to the quasi-position and enhance the precision of the drilling of the substrate.

Description

technical field [0001] The invention relates to a calibration method for drilling a printed circuit board, in particular to a method for correcting the alignment between a printed circuit board and a drilling blade before drilling a printed circuit board. Background technique [0002] Printed circuit board (PCB, hereinafter referred to as substrate) must first drill at least three positioning holes (Tooling holes) on the substrate or make at least three optical points through the exposure process before drilling parts holes for soldering electronic components. , the positioning hole and the optical point are collectively referred to as the target point, which can be used to correct the alignment between the substrate and the drilling blade. The drilling blade is a drilling machine with a fine drill bit. [0003] The above-mentioned method of using the target point to correct the substrate level is traditionally to respectively perforate a positioning column in each positioni...
