Automatic circuit board welding device

The invention discloses an automatic circuit board welding device. The automatic circuit board welding device comprises a bottom supporting frame, a first support, at least one heating device, at least one welding device, a processing device, a movement device, a driving device, a material taking mechanism and a feeding device. An air outlet of each heating device is arranged above one heating station. Each welding device corresponds to one welding station. The processing device is connected with each welding device and gives out welding signals to drive the welding devices to carry out welding actions. The movement device drives a jig of each heating station and a jig of each welding station to move after receiving the movement signals sent by the driving device. The driving device is connected with the processing device to receive movement instructions sent out by the processing device. The material taking mechanism is used for grabbing welded material pieces. One end of the feedingmechanism is connected wi
