[0002] Generally, electronic products are designed by adding various electronic components such as capacitors and resistors to PCB boards according to the designed circuit diagram. Therefore, various electrical appliances require various SMT patch processing technologies to process. The SMT patch process includes: solder paste printing, parts patch, reflow soldering, AOI optical inspection, maintenance and CNC machine tool panel separation.

[0003] During the process of mounting electronic components, the PCB board needs to be clamped on the conveying device in advance. The conveying device clamps the PCB board and continuously moves to the workstation where the components are mounted. After the mounting process is completed, the conveying device transports the PCB board with the components mounted thereon out of the mounting station. In order to improve the manufacturing efficiency of the PCB board, multiple sets of circuits are usually printed on a large board at the same time. Therefore, the overall size of the PCB board is relatively large. For different circuit structures, the size of the PCB board is different. The existing conveying device can only clamp PCB boards of a certain size. For PCB boards of other sizes, they need to be customized separately, which increases the cost of the mounting process. Therefore, a SMT production tooling is proposed to address the above problems. Utility Model Content
