[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0046] The working principle of the present invention is as follows: first, clamp the PCB board and place it in the middle of the two clamping bars 59, start the electric telescopic rod 51 to drive the transmission plate 53 at the output end to move backward in a straight line, and when the transmission plate 53 moves, the two transmission holes 54 on it squeeze and drive the two transmission shafts 56, so that the two transmission shafts 56 drive the two sliders 55 to move toward the opposite side on the surface of the limit rod 52, and the two sliders 55 drive the two connecting bars 57 to drive the two clamping bars 59 through the spring bars 58 on both sides to clamp the two sides of the PCB board, and the elastic characteristics of the spring bars 58 on both sides provide buffering force, and then start the automatic soldering device body 8 to process the surface of the PCB board (start the electric telescopic rod 51 to drive the transmission plate 53 to move forward to release the clamping and then use professional tools to pick it up and take it away), Restart the motor 33 and let it drive the small gear 34 to rotate through the output shaft. When the small gear 34 rotates, it drives the large gear 38 meshing with it to rotate between the two support bars 32 through the rotating shaft 35. When the rotating shaft 35 rotates, the two first sprockets 37 on its surface rotate synchronously. When the two first sprockets 37 rotate, they drive the two second sprockets 39 to rotate in the inner walls of the two support bars 32 through the two adapter shafts 36 through the two chains 310. When the two adapter shafts 36 rotate, they drive the connecting groove 4 and all the structures inside it, including the supported PCB board, to rotate, so that the other side of the PCB board faces upward. Before the connecting groove 4 is turned over, it rests on the supporting column 11 at the rear, and after it is turned over, it rests on the supporting column 11 in the front. The supporting column 11 provides support for it. Finally, the automatic soldering device body 8 is started to process the other side.
