[0048] After the PCB is placed on the backing plate 43, the adjusting buckle 44 is rotated to fix the PCB, and then the sliding assembly 40 is used to transport it to a suitable position;

[0049] like Figure 1 and Figure 4-Figure 6 As shown, a through-hole mechanism 3 is fixedly provided on one side of the upper end of the box body 1 away from the PCB board discharge position, and the through-hole mechanism 3 is used to perform through-hole processing on the PCB board;

[0050] The through-hole mechanism 3 includes a transmission assembly 34 fixedly connected to the upper end of the box body 1, and the transmission assembly 34 includes a base 345 fixedly connected to the box body 1;

[0058] The two sets of knife clamps 315 are defined as a first knife clamp and a second knife clamp. The first knife clamp has a back-slurry knife 311 at its lower end, while the second knife clamp has a scraper 312 at its lower end.

[0059] A first cylinder 317 is fixedly provided on the upper end of the fixed block 314, and the first cylinder 317 is used to adjust the scraping pressure at the lower end;

[0060] When drilling, the transmission component 34 will bring the squeegee mechanism 31 close to the PCB board, and then put the silver paste on one side of the stencil 33, and then use the transmission component 34 and the scraper 312 and the return knife 311 in the squeegee mechanism 31 to scrape the silver paste back and forth evenly.

[0061] like Figure 1 and Figure 7 As shown, a through-hole mechanism 2 is fixedly provided at the upper end of the box body 1. The through-hole mechanism 2 is located at a position where the conveying mechanism 4 is away from the through-hole mechanism 3.

[0065] When the PCB board is transported to the through-hole mechanism 2 by the conveying mechanism 4 after being through-holed, the second cylinder 22 will push the through-hole plate 26 toward the PCB board to make through-holes in the PCB board, so that only an appropriate amount of silver paste is left in the hole to avoid occlusion;

[0066] In summary, when a PCB board is to be through-holed, the PCB board is first placed on the pad 43 and fixed using the adjustment buckle 44, and then transported to the bottom of the squeegee mechanism 31 using the conveying mechanism 4;

[0067] Then the transmission assembly 34 will bring the squeegee mechanism 31 close to the PCB board, and then put the silver paste on the stencil 33, and then use the transmission assembly 34 and the scraper 312 and the return knife 311 in the squeegee mechanism 31 to scrape the silver paste so that the silver paste can fully enter the holes;

[0068] After the final through-hole is completed, the conveying mechanism 4 brings the PCB board back to the bottom of the through-hole mechanism 2. At this time, the second cylinder 22 will push the through-hole plate 26 closer to the PCB board. The multiple sets of through-hole wires (not marked in the figure) on the through-hole plate 26 will through-hole the PCB board, leaving only an appropriate amount of silver paste in the hole to avoid occlusion.
