It further include having controller, the oxidation detector 4, inlet tube flow control valve 5-5, goes out liquid at liquid level sensor 5-8
Pipe flow control valve 5-7 is connect with controller.
The working principle of embodiment one is as follows: copper foil is released from let off roll, is then set above the direction of advance of copper foil
Set oxidation detector 4, aoxidize detector 4 quantity can wide detected of full width to copper foil (guarantee copper foil longitudinally, laterally
Color difference can be detected), result is sent to controller by oxidation detector 4, controller to the result of oxidation detector 4 into
(the oxidation detector 4 of the application is also to belong to the prior art, such as using based on image analysis basis for row analysis
201710487620.6 modes recorded), if testing result is more than predetermined value, then send a signal to: inlet tube flow control
Valve 5-5, outlet tube flow control valve 5-7, adjusted by inlet tube flow control valve 5-5, outlet tube flow control valve 5-7 into
The amount of liquid pipe and the amount of outlet tube, so that the liquid level in groove body 5-4 is adjusted to scheduled oxygen from the position lower than blocking roller 5-3
Change washing height；
The oxidation rinsing height is higher than blocking roller 5-3, is fed back by liquid level sensor 5-8, i.e., liquid level passes
Signal is fed back to controller by sensor 5-8, and controller is sent a signal to: inlet tube flow control valve 5-5, outlet tube flow control
Valve 5-7, so that the amount of feed liquor, out liquid keeps dynamic equilibrium；
Copper foil is after oxidation rinsing device 5, into clear water washer 6, after washing, subsequently into baker 7, most
It is packed up afterwards by wind-up roll 9.
Clear water washer 6 is identical as the composition of oxidation rinsing device 5, and difference is, flows into groove body in clear water washer 6
Be water, and it is pickling solution that it is intracorporal, which to flow into slot, for oxidation rinsing device 5.
The concept of embodiment one is: inlet tube and outlet tube can be generally arranged in oxidation rinsing device 5, the purpose is to for
Pickling solution is put into or flowed out groove body；Also, for the precipitating for adjusting the concentration of solution in real time and reduction is likely to occur
The problems such as object, is generally to maintain solution and is in flow regime.
Inventor on this basis, analysis: how to make copper foil contact and separate with solution, there are two types of mode: 1 be by
Blocking roller is set as mobile, and 2 be the height for adjusting liquid.First way needs continuous extruding copper foil, may lead
It causes copper foil to generate and draws line；And the above problem is then not present in the second way.
And the height of liquid is adjusted, flow control valve is set on inlet tube or outlet tube, can be realized, e.g., is only existed
Flow control valve is set on outlet tube, and when needing to improve liquid level, the flow control valve on outlet tube reduces the outflow of outlet tube
Speed, and the input duct rate of outflow is remained unchanged or is increased, and can be realized；
Only flow control valve is set on inlet tube, the flow velocity of outlet tube is constant, when needing to improve liquid level, passes through raising
The flow of inlet tube；When needing reduces liquid level, by the flow for reducing inlet tube.
Above-mentioned single flow control valve design, can complete the rise and fall of liquid level, however, its operation to liquid level
Speed is relatively slow, also, flow control valve is only arranged on outlet tube, when Yao Tigao liquid level, due to inlet tube flow without
Therefore method adjustment is promoted indeed through the flow for reducing outlet tube, and do so the circulation that will affect groove body solution
Speed.Therefore, for oxidation rinsing device 5, it is respectively provided with flow control valve on inlet tube, outlet tube, can be met simultaneously
The promotion of liquid level reduces speed and to both demands of solution circulation rate.
The liquid level control means of oxidation rinsing device 5 are as follows: the groove body before let off roll 1 unreels, in oxidation rinsing device 5
Start promoted liquid level operation, until liquid level reaches low liquid level；
When oxidation detector 4 detects the presence of color difference problem for the first time, inlet tube flow of the controller to oxidation rinsing device 5
Control valve, outlet tube flow control valve issue signal, and liquid level is increased to high liquid level from low liquid level, and liquid level stops rising；
When liquid level reaches low liquid level and high liquid level, by liquid level sensor 5-4 come trigger signal to controller.
The difficult point of liquid level control is, improves liquid level under what circumstances, which kind of reduces liquid level in the case of, which kind of feelings
Liquid level is maintained under condition, that is, provides the logic judgment criterion of above situation.And above-mentioned criterion situation in need of consideration is numerous, especially
In the presence of under neighbouring color difference region this how to solve.
In conjunction with the Liquid level mode of the application, the Liquid level mode of the application is as follows:
Liquid level time module W is set in controller；
When oxidation detector 4, which detects the presence of copper foil, there are problems that color difference,
Liquid level time module W zero starts timing, meanwhile, liquid level sensor transmits signal to control；
If liquid level=high liquid level, controller issues signal to inlet tube flow control valve, outlet tube flow control valve:
Keep liquid level；
If liquid level < high liquid level, controller issues signal to inlet tube flow control valve, outlet tube flow control valve:
Liquid level is improved until being in high liquid level；
As liquid level time module W=preset time W1, liquid level time module W stops timing, meanwhile, controller is to feed liquor
Pipe flow control valve, outlet tube flow control valve issue signal: liquid level starts to reduce, until low liquid level (is reduced to from high liquid level
Color difference problem is not detected in the period internal oxidition detector 4 of low liquid level).
The minimum value of preset time W1 are as follows: copper foil autoxidation detector 4 to the time for leaving oxidation rinsing device 5, time
It can value according to practical condition are as follows: 5-20s.
The actual effect of above-mentioned Liquid level mode are as follows: if neighbouring copper foil color difference region < preset time W1 × copper foil
Forward speed, liquid level are constantly in high liquid level.If neighbouring copper foil color difference region > preset time W1 × copper foil forward speed,
Then liquid level can obtain: " promotion-reduction " operational order.
For clear water washer 6, its purpose is to by the pickling solution washes clean of copper foil surface.When it is designed,
Have to the circulation in view of aqueous solution.Therefore, the inlet tube of clear water washer 6, the effect of flow control valve is set on outlet tube
Fruit is also more preferably.
But clear water washer 6 and oxidation rinsing device 5 the difference is that, for copper foil, when oxidation detector
4 find after there is color difference that the liquid level of oxidation rinsing device 5 can be higher than blocking roller 5-2 for the first time；Hereafter under certain condition, oxygen
The liquid level for changing washer 5 can be lower than blocking roller 5-2.And clear water washer 6 for the first time find color difference problem after, on height of water level
After rising, it is no longer necessary to reduce, on the one hand, be to give subsequent normal copper foil since the blocking roller of clear water washer 6 speckles with acid solution
Acid solution is speckled with, therefore, there is a continuing need for washings for subsequent copper foil.
Further, it is additionally provided with pump 5-6 in the inlet tube of oxidation rinsing device 5, inlet tube flow control valve is set
Front.It is the flow velocity for further increasing inlet tube that the pump main purpose of 5-6, which is arranged, and pump 5-6 is also connect with controller.
It should be noted that flow control valve use the prior art, such as 201580045280.0,201310048457.5,
201610728793.8 waiting.
Embodiment provided above is better embodiment of the invention, only is used to facilitate to illustrate the present invention, not to this hair
It is bright to make any form of restriction, any those of ordinary skill in the art, if not departing from the proposed skill of the present invention
In the range of art feature, using the equivalent embodiment for locally changing or modifying made by disclosed technology contents, and
