[0002] PCB production refers to the manufacturing process of printed circuit boards (PCBs). This process involves a variety of technologies and techniques to ensure the high performance and reliability of the boards. During PCB manufacturing, immersion gold (Immersion Gold) is a key surface treatment technique. Immersion gold, which deposits a layer of metallic gold on the copper surface of the PCB, effectively improves the board's solderability and corrosion resistance.
[0003] Existing PCB immersion gold (IPG) processes typically utilize a combination of semi-manual and semi-mechanical processes. While this approach improves production efficiency to a certain extent, it also presents numerous inconveniences. The semi-manual operation introduces human interference, potentially leading to unstable product quality. For example, the operator's skill level and work attitude directly impact the quality of the IPG process, resulting in a reduction in yield. Furthermore, semi-mechanized production processes often struggle to achieve true standardization and consistency. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, a PCB board automatic gold immersion production equipment includes a base plate 1, a gold immersion pool 2 is fixedly connected to the top of the base plate 1, and the two sides of the damaged gold immersion pool 2 and the top of the base plate 1 are fixedly connected, a first connecting frame 3 and a second connecting frame 4 are fixedly connected, a displacement plate 5 is arranged between the first connecting frame 3 and the second connecting frame 4, a displacement assembly is arranged between the first connecting frame 3 and the second connecting frame 4, the displacement assembly is used to drive the displacement plate 5 to move, a lifting plate 8 is arranged at the bottom of the displacement plate 5, and a clamp 9 is fixedly connected to the bottom of the lifting plate 8. The interior of the gold immersion pool 2 is connected to two stirring blades 16 for rotation, a stirring assembly is arranged at the bottom of the base plate 1, and the stirring assembly is used to drive the two stirring blades 16 to rotate, the top of the displacement plate 5 is connected to the mounting plate 6, and the top of the mounting plate 6 is fixedly installed with an electric cylinder 7, and the output end of the electric cylinder 7 passes through the mounting plate 6 and the displacement plate 5 and is fixedly connected to the lifting plate 8.
[0023] When producing PCB boards, first, the PCB board to be processed with immersion gold is fixed to the bottom of the lifting plate 8 using a clamp 9, and then the displacement component is used to drive the displacement plate 5 to move, so that the PCB board fixed by the clamp 9 is synchronously moved to the top of the immersion gold tank 2, and then the electric cylinder 7 is used to push the lifting plate 8 to move so that the PCB board is immersed in the immersion gold liquid. During the immersion gold processing, the two stirring blades 16 are driven by the stirring component to rotate inside the immersion gold tank 2. By stirring the immersion gold liquid, it can be ensured that the metal salts and other chemical components in the immersion gold liquid are evenly distributed, avoiding excessively high or low metal concentrations in certain areas of the liquid, thereby affecting the quality and uniformity of the immersion gold, and at the same time preventing poor deposition, uneven thickness of the immersion gold layer, or even holes or defects, thereby affecting the overall effect of the gold layer on the PCB.
[0024] like Figure 1-Figure 5As shown, the displacement assembly includes a through slot 10 and a slide slot 13, which are respectively opened inside the first connecting frame 3 and the second connecting frame 4. A threaded rod 11 is rotatably connected between the inner walls of the through slot 10, and a connecting block 14 is threadedly connected to the outer side of the threaded rod 11. One side of the connecting block 14 is fixedly connected to the displacement plate 5, and a slider 15 is fixedly connected to the side of the displacement plate 5 away from the connecting block 14. The outer side of the slider 15 is slidably connected to the inner wall of the slide slot 13. A servo motor 12 is fixedly installed on one side of the first connecting frame 3, and the output end of the servo motor 12 extends to the inside of the through slot 10 and is fixedly connected to the threaded rod 11.
[0025] The servo motor 12 drives the threaded rod 11 to rotate between the inner walls of the through groove 10. The rotation of the threaded rod 11 causes the connecting block 14 to slide between the inner walls of the through groove 10, so that the displacement plate 5 moves with the assistance of the slider 15, thereby facilitating the movement of the PCB board fixed by the clamp 9, and further facilitating the automatic immersion gold production of the PCB board.

By stirring the gold precipitation liquid, the metal concentration in certain areas of the liquid is prevented from being too high or too low, thereby affecting the quality and uniformity of the gold precipitation.
[0028] The utility model provides an automatic immersion gold production equipment for PCB boards. The specific working principle is as follows: when performing PCB board production work, first use the clamp 9 to fix the PCB board to be immerged gold processed on the bottom of the lifting plate 8, then use the servo motor 12 to drive the threaded rod 11 to rotate between the inner walls of the through groove 10, and the rotation of the threaded rod 11 causes the connecting block 14 to slide between the inner walls of the through groove 10, so that the displacement plate 5 moves under the auxiliary action of the slider 15, so that the PCB board fixed by the clamp 9 is synchronously moved to the top of the immersion gold pool 2, and then the electric cylinder 7 is used to push the lifting plate 8 to move, so that the PCB board Immersed in the immersion gold liquid, during the immersion gold processing, the stirring motor 21 drives the active roller 18 to rotate between the U-shaped plate 17 and the bottom plate 1, and the transmission belt 20 drives the driven roller 19 to rotate at the same time, so that the two stirring blades 16 rotate at the same time inside the immersion gold tank 2.
