The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of compact conformation, the easy to use and respond well circuit board with automatic powder adding medicine adding function to process and use the wet film developing machine.
The technical solution of the utility model is achieved in that a kind of circuit board processing with automatic powder adding medicine adding function uses the wet film developing machine, comprises developing trough, and wherein said developing trough side wall upper part is provided with high-order run-down pipe; Be provided with brace table at the developing trough side, the height of described brace table is higher than the height of developing trough, is provided with the storage tank that stores development liquid medicine at brace table, and described storage tank bottom is connected with developing trough by chemical feed pipe, is provided with flow control valve at chemical feed pipe.
The above-mentioned circuit board processing with automatic powder adding medicine adding function is with in the wet film developing machine, described storage tank top vertically is provided with stirring motor, be provided with stirring arm in storage tank, the power output shaft of described stirring motor is fixedly connected with the rotating shaft of stirring arm; Also be provided with sodium carbonate charge door and tap water entrance at the storage tank top, described tap water entrance is connected with outside tap water supply pipeline by water pipe, is provided with operation valve at water pipe.
The above-mentioned circuit board processing with automatic powder adding medicine adding function is with in the wet film developing machine, and the chemical feed pipe between described flow control valve and the storage tank is provided with switch valve.
The above-mentioned circuit board processing with automatic powder adding medicine adding function is with in the wet film developing machine, and described brace table side is provided with step.
After the utility model adopts said structure, by setting up storage tank, and the mode of employing high potential difference fluid infusion, do not need to use external drive, can carry out liquid medicine to developing trough and add, by adding liquid medicine, both can replenish the problem of chemical concentration step-down, and can by the rising of liquid medicine water level, the dregs of fat in time flowed out from high-order run-down pipe again, guarantee effect and the quality of development, guarantee the quality of circuit board.The utlity model has advantage simple in structure, that processing cost is low, easy for installation.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Among the figure: developing trough 1, high-order run-down pipe 2, brace table 3, storage tank 4, sodium carbonate charge door 4a, tap water entrance 4b, chemical feed pipe 5, switch valve 5a, flow control valve 6, stirring motor 7, stirring arm 8, water pipe 9, operation valve 9a, step 10.
