Abstract

The invention discloses a pcb welding device which comprises a hollow pipe. One end of the hollow pipe is in sealing connection with a discharging device, and the other end of the hollow pipe is in sealing connection with a connecting part. The discharging pipe is in a funnel shape, and an end cover is detachably arranged on a conical part of the discharging device. A piston is arranged in the hollow pipe, and a copper pipe is arranged on the piston in a penetrating manner in the axis direction of the piston. The outer wall of the copper pipe is in sealing connection with the piston. The copper pipe penetrates the connecting part and can slide along a movable part, and a handle is arranged at the position, different from the end connected with the piston, of the copper pipe. A spring is arranged in the hollow pipe and located between the piston and the discharging device. The hollow pipe is sleeved with a shell, and the two ends of the shell are connected with the discharging device and the connecting part respectively. A heat insulation pad is arranged between the shell and the hollow pipe. A resistance wire is arranged between the heat insulation pad and the hollow pipe. A heat conduction insulation layer is arranged between the hollow pipe and the resistance wire. In the process of utilizing the device for pcb welding, operation standardability is easy to control, and welding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pcb welding, and in particular relates to a pcb welding device. Background technique [0002] At present, when circuit developers use electric soldering irons to solder component pins, they usually use the right hand to hold the electric soldering iron and the left hand to hold the solder wire, and the electric soldering iron melts the solder wire for soldering. This manual pcb soldering method is difficult to control due to the standardization of operation , Different operators make the quality of welding vary, short circuit, short circuit, virtual welding and other problems often occur, the pass rate of the product is not high and the shape of the joint after welding is not beautiful. Contents of the invention [0003] The object of the present invention is to provide a pcb welding device to solve the technical problem in the prior art that the operation standardization is difficult to control during ...
