Description

Technical Field

[0002] With the rapid development of the electronics manufacturing industry, surface mount technology (SMT) has become one of the core technologies in the manufacturing of modern electronic products. The automated SMT patch production line has achieved rapid and accurate placement of electronic components through highly integrated equipment and technology, greatly improving production efficiency and product quality. In the automated SMT patch production process, solder paste printing is one of the key processes, and its efficiency and accuracy directly affect the quality of subsequent placement and welding. Although automation technology has been widely used in SMT patch production, traditional solder paste printing tooling still has many shortcomings in terms of efficiency, accuracy and stability, and it is difficult to meet the needs of modern electronic products for high-precision and high-efficiency production.

[0003] Although the traditional automated SMT patch production line has achieved rapid placement of components, the solder paste printing process still adopts a single-step operation mode, that is, solder paste printing is carried out after the PCB is loaded, which cannot achieve continuous production and leads to the inability to further improve production efficiency; during the movement of the PCB, the traditional tooling lacks an effective stabilizing device, which can easily cause the PCB to shift, affecting the accuracy and quality of solder paste printing, and further affecting the accuracy of subsequent placement and welding; the power transmission structure design of the traditional tooling is not compact enough, resulting in low power transmission efficiency, increased energy consumption and production costs; during the operation of the traditional tooling, due to unreasonable structural design, friction and wear are easily generated, shortening the service life of the device and increasing maintenance costs; some improved tooling attempts to achieve continuous PCB loading and solder paste printing by adding conveying devices and rotating devices, but in actual applications, due to the lack of compact structural design, it is difficult to ensure the stability and accuracy of PCB movement.

[0004] How to reduce production costs, reduce friction and wear, and extend the service life of the device while ensuring high-precision and high-efficiency production is the main challenge facing the current solder paste printing tooling technology; the present invention realizes continuous loading and solder paste printing of PCBs through the coordinated work of a supporting device, a driving device, a transmission device, a rotating device, a conveying device and a solder paste printer, and significantly improves production efficiency; the stability and accuracy of the PCB during movement are ensured through the compact design of the transmission device and the rotating device; the high efficiency and stability of power transmission are ensured through the efficient meshing design of the worm and the gear, and the compact structural design saves space and facilitates installation and maintenance.

[0005] Aiming at the deficiencies of the solder paste printing process in the traditional automated SMT patch production in terms of efficiency, precision and cost, the present invention proposes a novel solder paste printing tooling technical solution for SMT patch production. Through the coordinated work of multiple devices, continuous loading and solder paste printing of PCBs are realized, which significantly improves the production efficiency, ensures the stability and precision of PCBs during movement and printing, reduces friction and wear, and prolongs the service life of the device, thus having broad application prospects.

At the same time, the original eighth rectangular plate 48 at the top rotates to the bottom to load the PBC and rotate. When the PBC with solder paste rotates to the same horizontal plane as the pushing end of the first high-precision electric push rod 14, the PBC with solder paste is pushed by the first high-precision electric push rod 14 to be output to the next device. The present invention can automatically print solder paste on the PBC to achieve higher efficiency.
