[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The airflow component 2 can store a portion of the air pumped in from the outside. When the welding operation is about to begin and the welding head component is pressed down, this action can trigger the relevant release component, which will quickly release the high-pressure air previously accumulated inside. The released high-pressure air will be blown out strongly toward the working area, thereby blowing the dust in the working area away from the area. In this way, the amount of dust in the working area can be greatly reduced, effectively preventing dust from entering the solder, and avoiding the occurrence of loose welding, cold welding, etc. (2) The air duct has a dual function. On the one hand, it can guide the air to enter the gas tank smoothly. On the other hand, when the gas tank is filled with air, the air duct can change the direction of the air flow and guide it to the mold assembly. With the help of this air flowing to the mold assembly, the card block that has completed the work can be initially cooled down. At the same time, for the card block that is about to be put into welding, this air flow can reduce its temperature to a suitable range. In this way, in the subsequent welding process, when the card block comes into contact with the solder, due to its own suitable temperature, it can quickly and efficiently absorb and take away the heat of the solder, thereby accelerating the cooling speed of the solder. This can avoid subsequent operations before the solder is completely cooled, resulting in unsuccessful welding or quality problems such as desoldering due to poor solder cooling. It is also worth mentioning that the rotating assembly can use the downward pressure of the welding head assembly to use this force to drive the mold assembly to rotate. This setting not only allows the mold assembly to complete the rotation without the need for additional control components, but also allows each rotation to be completed before processing and blowing.

[0030] The working principle and use process of the present invention are as follows: before welding, the external air pump needs to be connected to the airway 4; when the gas starts to flow in the airway 4 and passes through the airflow component 1 5, the airflow will push up the sealing plate 2 505; at this time, the sealing plate 1 504 closes one side of the shell 501, thereby ensuring that the air can only enter the gas tank 601 in one direction; as the gas is continuously injected, when the pressure in the gas tank 601 reaches a certain level and the air pump can no longer inject more air into the gas tank 601, the spring 1 503 plays a role, driving the sealing plate 1 504 and the sealing plate 2 505 to return to the initial position, so that the other end of the airway 4 is conductive, and at this time, the block 702 can be cooled, thereby effectively improving the stability and reliability of the equipment operation and ensuring the efficient welding work; When the gas tank 601 is filled with gas, the internal pressure increases, and the upper sealing block 605 will be pushed to the uppermost position under the pressure; during the welding operation, when the welding head assembly 2 moves downward and presses on the upper sealing block 605, the upper sealing block 605 and all the components below it will move downward together; this process continues until the lower sealing block 603 is tightly pressed against the mounting table 3, at which time the channel of the nozzle 602 is opened, and the compressed air in the gas tank 601 can be quickly ejected from the nozzle 602, forming an airflow to blow away the dust on the upper end of the block 702, thereby ensuring the cleanliness of the welding part. , improving the welding quality; it should be particularly pointed out that the cooperation of the telescopic rod 604 and the second spring 606 plays an important role in this process; when the welding head assembly 2 continues to move downward, even if the lower sealing block 603 stops moving due to pressing on the mounting table 3, due to the telescopic characteristics of the telescopic rod 604 and the elastic buffering of the second spring 606, the upper sealing block 605 and the components above it can still continue to move downward for a certain distance relatively independently, thereby not hindering the welding head assembly 2 from continuing to move downward until the welding head assembly 2 presses down all the pressing rods, thereby ensuring the continuity and efficiency of the entire welding process; During the welding operation, when the welding head assembly 2 starts to move downward; first, before the welding head assembly 2 releases the lower sealing block 603, it will first apply downward pressure to the telescopic plate 802; after the telescopic plate 802 is pressed downward, it will generate a corresponding driving force, thereby driving the rotating shaft 701 to rotate; through the rotation of the rotating shaft 701, those blocks 702 that have completed cooling can be moved to the working position to prepare for subsequent welding; then, as the welding head assembly 2 continues to move downward, the gas stored in the gas tank 601 is released, and the high-speed gas can blow away the new blocks 702, pins and dust attached to the surface of the connecting wires, effectively removing impurities, thereby ensuring that the quality of each welding operation can reach a high level; in addition, it is also necessary to pay attention to When the telescopic plate 802 is pressed down, the shift block 805 will produce a corresponding action, which can apply downward pressure to the card block 702, so that the original slot 707 can be separated from the range of the original pin 706; and, as the shift block 805 continues to push, the slot 707 can be combined with the pin 706 again after being separated. In this way, the rotation angle of the shaft 701 can be accurately controlled to meet the requirements of the welding work for the position of the card block 702 and other aspects; and when the welding operation is completed, the inclined surface of the shift block 805 will shrink to one side under the squeezing action of the card block 702, thereby realizing the reset of the shift block 805 itself, waiting for the next press, and so on and so forth, to ensure the orderly cooperation and normal operation of the relevant components in the entire welding process; After the block 702 is used, it will rotate to the non-working area to start the cooling process; in the initial stage, the block 702 relies on the heat exchange between itself and the surrounding environment to cool naturally to dissipate the heat accumulated in the working process; as the block 702 enters the second stage after two rotations, the air flowing in the airway 4 is used to achieve preliminary heat dissipation; when the block 702 rotates half a circle and is connected to the other end of the airway 4, the air temperature it contacts is lower, so that this part of the lower temperature air can be used to efficiently cool the block 702 that is about to enter the working state, so that it can reach a suitable working temperature, ensuring that the heat of the solder can be taken away faster in subsequent use.
