Embodiment 1

[0048] Embodiment 1 provided by the present invention is an embodiment of a PCB board coating equipment that uses laser to directly cover the PCB board provided by the present invention. The embodiment of the equipment includes: customer management system, CCD (Charge-coupled Device, charge coupled device) automatic positioning system and laser marking machine.

[0049] The customer management system stores code rewriting rule data.

[0050] The CCD automatic positioning system locates the PCB board, controls the laser marking machine to cover the PCB board according to the code covering rule data, and reads the QR code or one-dimensional code on the PCB board after the code is covered, and reads it The data is sent to the customer management system for comparison.

[0051] The laser marking machine includes a carbon dioxide laser, an X-axis scanning mirror, an X-axis galvanometer, a Y-axis scanning mirror, a Y-axis galvanometer, a field mirror and a computer control system. ...

Abstract

The invention relates to the field of PCB coding, and provides a direct coding method for a PCB. The direct coding method comprises the following steps: directly coding the PCB by using a carbon dioxide laser, wherein the size of the focus light spot of the carbon dioxide laser is equal to or smaller than 0.14 mm; aiming at two-dimensional codes or one-dimensional codes in different sizes requested on different PCBs, coding is realized by controlling the power of the carbon dioxide laser and selecting different coding modes. The high-precision, high-speed and programmable carbon dioxide laser is adopted to directly code the PCB, aiming at two-dimensional codes or one-dimensional codes in different requested sizes, the coding depth can be controlled by controlling the power of the carbon dioxide laser, and appropriate coding modes are selected, so that the PCB is not damaged in the coding process, automation can be achieved in the production process, and the labor and the materials can be saved; laser coding is not affected by assembling steps or environment, can be directly acted on the PCB, and the process lasting property is good, so that the effect that the code lasts for the whole life of the PCB is achieved.

Description

technical field [0001] The invention belongs to the field of coding on PCB boards, in particular to a method for directly covering codes on PCB boards. Background technique [0002] The method used for traceability of traditional PCB boards is to paste barcodes by hand. The process method is to print barcodes according to certain rules by a coding machine, and use manual or machine methods to paste the printed barcodes on the designated positions on the PCB board. [0003] The names are "PCB board automatic code scanning device" (public date: July 23, 2014, announcement number 203734917U) and "PCB board automatic scanning code cooling and static electricity transmission mechanism" (public date: December 31, 2014 , Announcement No. 204069505U) in the disclosed technical scheme, all are to comprise coding machine, conveying device and code scanning device, PCB board runs automatically on conveying device, and coding machine prints bar code and pastes on each PCB board successi...
