Preferably, the etching solution delivery pipe is equipped with filter.It can be filtered out by filter some from etching pump It is transported to the impurity of the etching solution in etching groove.

Preferably, the communicating pipe passes through union and spray supervisor's connection.Connection can be facilitated by union Cross over pipe is replaced after pipe damage.

Preferably, the spray, which is in charge of, is connected by valve with the communicating pipe.It can be adjusted by valve from communicating pipe It is passed to the flow that spray is in charge of interior etching solution, inside so as to adjust the pressure of the etching solution entered in etching groove.

Preferably, the spray, which is in charge of, is equipped with pressure gauge.Staff can be facilitated to observe at any time by pressure gauge Spray is in charge of the pressure of interior etching solution.

Compared with prior art, the utility model has the advantages that: the conveying of the etching solution of the etching section of the utility model is adopted Pump is etched with 55KW to complete, and 55KW etching pump is capable of providing bigger pressure and flow compared to traditional etching pump, leads to The mode of movement that the pump for traditional 8 smaller powers of use is pumped using 55KW etching is crossed, while reducing maintenance rate Scrapping for pcb board is decreased, meanwhile, it is conveyed and is etched to etching groove one, etching groove two and etching groove San Tong method using a pump Liquid, can guarantee to be transported to cutting one, etching groove two identical with the pressure of the etching solution in etching groove three, improve the steady of etching It is qualitative.
