Description
Technical field
The present invention relates to the technical field of stirring etching solution, particularly a kind of device for containing etching solution.
Background technology
At present, circuit board is in etching process, the copper bar on etching solution open circuit potential plate, continuous molten with copper product
Solution, the proportion of solution is constantly raised, after proportion exceedes certain value, and the etching solution of automatic compensation ammonium chloride and ammonia-water systems is adjusted
Whole proportion is to suitable scope.General specific gravity control is in 18 ~ 240Be.The pH value of the influence etching solution of solution pH value should be maintained at
Between 8.0 ~ 8.8.
When the pH value of etching solution is reduced to below 8.0, on the one hand it is unfavorable to metal resist layer, on the other hand, etches
Copper in liquid can not be complexed into ammoniacal copper complex ion completely, and precipitation occurs in solution, and in bottom land formation sludge, these precipitations
Sclerderm can be formed on the heaters, heater may be damaged, can also block pumps and nozzle, cause difficulty to etching.Only not
Disconnected stirring etching solution makes etching solution constantly move, to prevent solution from precipitating, when needing to use etching solution etched circuit
During plate, etching solution is released, it is at present, most of that etching solution is stirred using agitator, but the agitator structure is complicated, thereon
Stirring vane solution be etched corrosion, do not promote the use of.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art, there is provided a kind of compact conformation, manufacturing cost be low, operation is simple
The device of splendid attire etching solution single, that etching solution generation precipitation can be prevented effectively from.
The purpose of the present invention is achieved through the following technical solutions：A kind of device for containing etching solution, it includes support, watched
Take the column A that support is provided perpendicular on motor and storage tank, described support and column B, described servomotor perpendicular to
Column B sets and is fixedly mounted on column B, and the both sides of described storage tank are respectively arranged with rotating shaft I and rotating shaft II, rotating shaft I and
Rotating shaft II is symmetrical arranged, and the rotating shaft I other end is rotatably mounted on column A, the output end connection of rotating shaft II and servomotor, institute
The die cavity for containing etching solution is provided with the storage tank stated, top, the bottom of storage tank are respectively arranged with inlet, liquid outlet,
Inlet and liquid outlet are connected with die cavity, and multiple air inlets connected with die cavity are provided with two side walls of described storage tank
Mouthful.
It also includes controller, and described controller is connected with servomotor.
Stop valve is respectively connected with described inlet and liquid outlet.
The present invention has advantages below：The present invention storage tank two side walls on be provided with it is multiple connected with die cavity enter
Gas port, the pressure-air of cleaning is passed through through air inlet into storage tank, and pressure-air promotes etching solution to do irregular in die cavity
Moving back and forth, and combine motor drives storage tank to rotate, and effectively avoids etching solution and produces precipitation.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure, 1- supports, 2- servomotors, 3- storage tanks, 4- columns A, 5- column B, 6- rotating shaft I, 7- rotating shaft II, 8- type
Chamber, 9- inlets, 10- liquid outlets, 11- air inlets, 12- stop valves.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in figure 1, a kind of device for containing etching solution, it includes support 1, servomotor 2 and storage tank 3, described machine
The column A4 and column B5 of support 1 are provided perpendicular on seat 1, described servomotor 2 is set and fixed perpendicular to column B5
On column B5, the both sides of described storage tank 3 are respectively arranged with rotating shaft I6 and rotating shaft II7, and rotating shaft I6 and rotating shaft II7 are symmetrical
Set, the rotating shaft I6 other end is rotatably mounted on column A4, and rotating shaft II7 is connected with the output end of servomotor 2, described storage
The die cavity 8 for containing etching solution is provided with tank 3, top, the bottom of storage tank 3 are respectively arranged with inlet 9, liquid outlet 10,
Inlet 9 and liquid outlet 10 are connected with die cavity 8, and stop valve 12 is respectively connected with described inlet 9 and liquid outlet 10.It is described
Storage tank 3 two side walls on be provided with multiple air inlets 11 connected with die cavity 8.
It also includes controller, and described controller is connected with servomotor 2, can control servomotor 2 by controller
Startup or closing, while the rotating speed of servomotor 2 can also be controlled, operation is very easy.
The course of work of the present invention is as follows：The stop valve 12 at inlet 9 is first opened, it is a certain amount of toward the interior injection of die cavity 8
Etching solution is then turned off the stop valve 2, then controls the startup of servomotor 2, and servomotor 2 drives rotating shaft II7 to rotate, rotating shaft
II7 drives storage tank 3 to rotate, so as to drive etching solution to rotate, while being passed through through air inlet 11 into storage tank 3 clean
Net pressure-air, pressure-air promotes etching solution to do irregular reciprocating motion in die cavity 8, and combines rotary motion, has
Effect avoids etching solution and produces precipitation.When etching solution to be taken, servomotor 2 need to be only closed, cutting at liquid outlet 10 is opened
Only valve 12, etching solution is released.
