Wave-soldering tool for PCB (printed circuit board) processing

The utility model discloses a wave-soldering tool for PCB processing, which relates to the technical field of PCB processing equipment and comprises a box body and a fixing mechanism, a welding machine is arranged at the upper end of the interior of the box body, and the fixing mechanism is arranged at the bottom end of one side of the welding machine. The fixing mechanism comprises a base, a first telescopic rod, a fixing rod, an electric rotating shaft, a connecting rod, a second telescopic rod, a fixing block, a cushion layer, a groove and an infrared sensor. The fixing mechanism is arranged on one side of the welding machine, the position of the SMT chip mounter core needing to be welded is recognized through the infrared sensor, and therefore the first telescopic air cylinder drives the electric rotating shaft at the bottom end of the fixing rod to move, angle adjustment is conducted on the second telescopic air cylinder under the action of the electric rotating shaft, and the SMT chip mounter core is we
