[0063] By adopting the above technical solution, by setting the second guide groove 57 and the second guide block 58, the second guide block 58 guides the L-shaped equipment frame 15 and the U-shaped sleeve 16 in the horizontal direction, so that the L-shaped equipment frame 15 and the U-shaped sleeve 16 are guided in the horizontal direction.

By setting the second telescopic rod 71 and the second telescopic spring 72, the second telescopic rod 71 and the second telescopic spring 72 extend, so that the movable seat 68 and the limiting rod 69 move horizontally toward the center position of the movable seat 17.

[0068] Working principle: When the circuit board needs to be welded, the welder first places the circuit board flat between the two placement chambers 11, with the side of the circuit board to be welded facing upwards, and solders the circuit on the upper surface of the circuit board through the operation slot 12, and then turns on the two electric cylinders 13, the piston ends of the two electric cylinders 13 extend, and the two rubber pressure plates 14 descend vertically, and the two rubber pressure plates 14 press the two ends of the circuit board tightly;

[0069] After placement, the welder connects the external air compression pump to the end pipe 43, and the negative pressure generated by the air pump operation enters the exhaust head 41 through the end pipe 43 and the connecting pipe 42, and is conducted through the exhaust head 41;

[0070] At the same time, the welding personnel turns on the motor 38, and the driving shaft of the motor 38 makes the corresponding first rotating rod 31 rotate. At this time, the two first rotating rods 31 transmit the transmission belt 33 through the two transmission wheels 32, and the transmission belt 33 makes the movable seat 17 reciprocate horizontally through the L-shaped synchronization rod 34 and the strip groove 35. The movable seat 17 makes the storage box 21 reciprocate horizontally through the first connecting rod 25. The multiple cleaning brushes 22 and the adsorption sponge 23 on the lower end surface of the storage box 21 move synchronously and reciprocate horizontally. The cleaning agent in the storage box 21 is adsorbed on the multiple cleaning brushes 22. The multiple cleaning brushes 22 adsorbed with the cleaning agent clean the upper surface of the circuit board to remove the oil, impurities and oxides on the surface of the circuit board. At the same time, the adsorption sponge 23 adsorbs the excess cleaning agent, dust and impurities on the upper surface of the circuit board, thereby conveniently realizing the cleaning of the circuit board, thereby effectively improving the convenience of cleaning the circuit board to be welded.

[0071] At the same time, the movable seat 17 causes the U-shaped sleeve 16 and the L-shaped equipment frame 15 to reciprocate synchronously through the second connecting rod 56, the second transmission rod 52 and the transmission gear 54 follow synchronously, the tooth plate 55 causes the transmission gear 54 to rotate, the transmission gear 54 causes the second transmission rod 52 to rotate, the second transmission rod 52 causes the first transmission rod 5 to rotate through the two second bevel gears 53, the first transmission rod 5 causes the second rotating rod 46 to rotate through the two first bevel gears 51, the second rotating rod 46 causes the driving rod 48 to rotate with the axis of the rotating disk 47 as the center of the circle through the turntable 47, the driving rod 48 causes the rotating handle 49 to reciprocate with the axis of the rotating shaft 45 as the center of the circle through the movable groove 491, the rotating handle 49 causes the rotating shaft 45 to reciprocate, the rotating shaft 45 causes the exhaust head 41 to reciprocate with the axis of the rotating shaft 45 as the center of the circle, and the exhaust head 41 expands the suction range during the reciprocating swing, performs a comprehensive suction treatment on the upper surface of the circuit board, further removes dust and impurities on the surface of the circuit board, and improves the cleaning effect;

[0072] When the cleaning of the circuit board is completed, the welding personnel manually press a connecting plate 61 on the side of the movable seat 17 close to the first connecting rod 25, so that the connecting plate 61 enters the telescopic groove 64, and the connecting plate 61 causes the first telescopic rod 65 and the first telescopic spring 66 to contract. When the connecting plate 61 completely enters the interior of the telescopic groove 64, the first connecting rod 25 is disengaged from the connecting hole 63. At the same time, the limiting holes 7 at both ends of the connecting plate 61 correspond horizontally to the two limiting rods 69. At this time, the two second telescopic rods 71 ​​and the two second telescopic springs 72 extend, pushing the two movable seats 68 to move toward each other. The two movable seats 68 cause the two limiting rods 69 to move toward each other, so that the two limiting rods 69 are horizontally inserted into the two limiting holes 7. At this time The two limit rods 69 limit and fix the connecting plate 61 so that the connecting plate 61 is fixed in the telescopic groove 64. When the movable seat 17 moves reciprocatingly horizontally, the L-shaped equipment frame 15 and the U-shaped sleeve 16 follow the movement, the cleaning brush 22 and the adsorption sponge 23 are in a stopped state, and the exhaust head 41 works alone. The exhaust head 41 extracts the smoke, aerosol, etc. generated during the welding process during the reciprocating horizontal movement and reciprocating swing, so as to prevent the smoke from being inhaled by the welder or entering the welder's eyes and causing harm to the welder. At the same time, the exhaust head 41 can quickly cool the high-temperature soldering to prevent the circuit board from shaking and causing the unsolidified soldering to be misaligned, thereby improving the quality of circuit board circuit welding.
