Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to an SMT front-end automated production line. Background Art

[0002] SMT (Surface Mount Technology) patch and reflow soldering are essential processes in the process of mounting components on flexible printed circuits (FPC). SMT production lines are usually used to perform patch and reflow soldering of components on flexible boards. During SMT production, the flexible board is placed in a high-temperature carrier (the high-temperature carrier includes a high-temperature resistant clamp and a steel sheet covering the area of ​​the flexible board that does not require patch) and flows on the production line. The SMT production line may include a solder paste printer, a patch machine and a reflow soldering equipment arranged in sequence. The high-temperature carrier equipped with the flexible board undergoes solder paste printing, parts mounting and reflow soldering in sequence to complete the SMT patch processing of the flexible board.

[0003] In traditional technology, although the SMT production line has introduced automatic loading and unloading equipment, manual operation is usually required when loading and unloading a variety of flexible board products, as well as implanting and flipping the flexible board. Sometimes it is necessary to switch different production equipment, and the changeover time is long, which affects production efficiency. Moreover, when reflowing the flexible board, the welding pressure bar cannot be detected and monitored in real time, which may cause problems with the welding quality of the flexible board. Summary of the invention

[0004] The present invention provides an SMT front-end automated production line, which can solve the technical problems in traditional technologies that, during SMT production, manual participation is often required, and sometimes different production equipment needs to be switched, resulting in low production efficiency, and the welding pressure strips for fixing the flexible board cannot be effectively detected during reflow soldering, which easily leads to welding quality problems on the flexible board.

[0007] A plate planting machine, comprising a plate planting seat, a plate planting loading and unloading mechanism and a plate planting material taking and placing mechanism respectively arranged on both sides of the plate planting seat, a plate planting material conveying mechanism arranged in the middle of the plate planting seat, and a first turning mechanism and a first translation platform mechanism respectively arranged at both ends of the plate planting material conveying mechanism, the plate planting material conveying mechanism is connected to the upper plate channel switching mechanism, and the plate planting material taking and placing mechanism is located above the plate planting loading and unloading mechanism and the plate planting material conveying mechanism;

[0010] The lower plate machine includes a lower plate channel mechanism having a plurality of lower plate conveying channel units arranged side by side, and a lower plate channel switching mechanism docked with the plurality of lower plate conveying channel units, wherein the lower plate channel switching mechanism is connected to the second flip plate feeding mechanism.

In the process of loading and unloading, automatic material changeover and transportation can be achieved without manual intervention, which is simple and efficient.

During the entire board planting process, there is no need for manual loading and unloading, nor is there a need for workers to flip the flexible board or move the high-temperature board or steel sheet. The board planting operation is performed on one device without switching equipment, which can greatly improve production efficiency, reduce errors caused by manual operation, and ensure the quality of board planting.

In this way, the welding pressure strips can be recycled, and the welding pressure strips can be detected and monitored in real time, so that unqualified welding pressure strips can be prevented from being circulated and used on the production line, and the welding quality of the flexible plate can be guaranteed.

[0015] In addition, the first flip plate feeding mechanism of the flexible plate flipping device receives and conveys the welded welding materials, and the steel sheet, flexible plate, and high temperature plate of the welding materials on the first flip plate feeding mechanism can be transferred respectively through the material transfer mechanism, and the high temperature plate, flexible plate, and steel sheet can be respectively transferred to the second flipping mechanism for flipping, and combined with the second translation stage mechanism, the high temperature plate, flexible plate, and steel sheet are implanted and combined again, and then the implanted high temperature plate, flexible plate, and steel sheet are transported to the next station through the second flip plate feeding mechanism to facilitate reflow soldering on the other side of the flexible plate. Similarly, in the entire flipping process, there is no need for manual loading and unloading, and there is no need for workers to flip and move the flexible plate, high temperature plate, and steel sheet. The flipping and implanting operations are realized on one device without switching equipment, which can greatly improve production efficiency, reduce errors caused by manual operation, and ensure the quality of implanting.
