Abstract

The invention discloses a PCB positioning error calibration method, device and equipment and a storage medium. The method comprises the steps of obtaining a reference coordinate value of a Mark pointfrom an image file comprising PCB information; Controlling a CCD to shoot the Mark point on the PCB to obtain an actual coordinate value of the Mark point; Comparing the reference coordinate value with the actual coordinate value to obtain an offset value of an image to be printed on the PCB; Storing the offset value in the image file, and analyzing the image file to obtain an offset coordinate value of the image; And obtaining a printing coordinate value according to the offset coordinate value and the positioning coordinate value of the PCB. According to the method, manual participation is not needed, automation is high, efficiency is high, and the printing position of the image on the PCB is accurate after recalculation.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a PCB board positioning error calibration method, device, equipment and storage medium. Background technique [0002] When printing the characters on the PCB board, since the position of the PCB board is easily shifted manually, the characters cannot be printed in the exact position when printing the characters. In order to print characters accurately, certain measures must be taken to accurately position the PCB board. In the PCB board design stage, designers usually make Mark points as positioning references. Only with accurate positional relationships can they be used for subsequent effective detection. Do the basics. For the problem of offset in manual PCB board placement, the existing method is to determine the moving distance of the motor through the Mark point on the PCB board, and then move the PCB board through the motor to place the board in an accurate positio...
