Full-automatic PCB laser coding machine with sorting function, method and system

Abstract

The invention provides a full-automatic PCB laser coding machine with a sorting function. The full-automatic PCB laser coding machine comprises a module mechanism, a track conveying mechanism, a lasercoding optical mechanism, a CCD visual positioning, code scanning and detecting mechanism, a PCB sensor and a control mechanism. The module mechanism can move in the horizontal direction, and movement of the module mechanism enables the laser coding optical mechanism and a CCD camera to synchronously move, enables the laser coding optical mechanism to move to the position above a PCB coding position, and enables the CCD camera to move to a PCB mark position or a position above the PCB coding position. The control mechanism responds to generate a warning signal when code reading results fed back by the camera are unqualified. According to the full-automatic PCB laser coding machine with the sorting function, a method and a system, the CCD visual positioning, code scanning and detecting mechanism automatically positions the coding position, after coding through the laser coding optical mechanism is completed, the CCD visual positioning, code scanning and detecting mechanism conducts code scanning and detecting, and the situation that the entire batch of products are scrapped due to the fact that PCB products coded badly are put in storage is avoided.

Description

technical field [0001] The invention relates to the field of laser coding machines, in particular to a fully automatic PCB laser coding machine, method and system with a sorting function. Background technique [0002] Laser marking technology is more environmentally friendly and economical than the inkjet method of the existing process. The permanent mark will not be easily erased.

Problems solved by technology

If there is an abnormality in a certain board during the production process, the production of the entire batch of boards will be suspended; if the boards that have been put into storage or sent to the customer are abnormal, after confirming the cause of the abnormality, all the boards in the entire batch need to be returned for inspection. The larger the optimal batch size, the more objects to be recalled for verification, which to a certain extent also causes a waste of human and material resources and costs

In addition, in the process of printing PCB circuit boards, due to the long processing process and the large number of equipment and personnel involved in each process, errors are easy to make during the production process. The traditional method increases manpower to set up checkpoint procedures and uses systems to restrain operators In order to prevent errors by increasing training or punishing parties and managers, it takes a lot of time and labor costs; in addition, the core board thickness, copper thickness, latitude and longitude, and material of multilayer boards of different codes may be similar Or the same, relying on human eye observation and control can easily lead to product confusion and errors, and the effect of human control is often poor; unqualified codes can only be controlled by manual quality control, which is not effective and efficient.

[0005] In addition, many PCB laser coding machine systems mainly rely on manual loading, unloading, and flipping. Accidents often occur, workers are injured, machines are damaged, or workpieces are damaged, resulting in a lot of labor costs, material costs, and time costs. waste of
