X-ray meter control system for printed circuit board (PCB) production

Abstract

The invention discloses an X-ray meter control system for printed circuit board (PCB) production. The X-ray meter control system for the PCB production comprises an upper computer monitoring machine, a lower computer control unit, an input unit and an actuating mechanism unit. The actuating mechanism unit comprises an X-direction drive motor, a Y-direction drive motor, a Z-direction drive motor, a light path rotating drive motor and an indicator light. The input unit comprises a manually-operated operation unit, an X-ray detector, an X-direction limit switch, a Y-direction limit switch, a Z-direction limit switch and a light path rotating limit switch. The lower computer control unit comprises an alternating current / direct current conversion unit, a current detection unit, a controller, an X-direction motor driver, a Y-direction motor driver, a Z-direction motor driver, a light path rotating motor driver and a motor driving line port. The X-ray meter control system for the PCB production is simple in structure, reasonable in design, convenient to use and operate, high in control accuracy and work reliability, not prone to break-down, and capable of improving PCB quality and PCB production efficiency and reducing energy consumption.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a control system of an X-ray detector for PCB board production. Background technique [0002] As the demand for modern electronic products increases, printed circuit boards, as an important part of modern electronic equipment, are more and more widely used, and electronic devices tend to be small in size, light in weight, and small in lead spacing. At the same time, high-density mounting circuits Board, dense pin wiring all lead to increased soldering defects. At the same time, some human factors cause defects such as PCB board design defects, poor solderability of circuit board holes, virtual soldering caused by stress deformation, and short circuits. Can directly affect the quality of the circuit board and even the performance of the product. At present, most of the quality inspection of circuit boards is completed by manual visual inspection, and the in...

AI Technical Summary

Problems solved by technology

At present, most of the quality inspection of circuit boards is completed by manual visual inspection, and the influence of human factors is prone to missed inspections and false inspections. Therefore, an online automatic defect detection system is urgently needed in the circuit board production process.

However, in the prior art, there is no defect detection system for PCB board production with complete functions and high detection accuracy.
