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 operation 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
Oxidation detector 4 is set, the quantity of oxidation detector 4 can be detected the full width width of copper foil（Ensure copper foil longitudinally, laterally
Aberration can be detected）, result is sent to controller by oxidation detector 4, controller to aoxidize the result of detector 4 into
Row analysis（The oxidation detector 4 of the application is also to belong to the prior art, such as using based on image analysis basis
201710487620.6 the mode 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, by inlet tube flow control valve 5-5, outlet tube flow control valve 5-7 come adjust 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 less 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 sensor
Signal is fed back to controller by 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 feed liquor, the amount for going out liquid keep dynamic equilibrium；
Copper foil is after oxidation rinsing device 5, into clear water washer 6, after washing, subsequently into baker 7, finally by
Wind-up roll 9 is packed up.
Clear water washer 6 is identical as the composition of oxidation rinsing device 5, and difference lies in flow into clear water washer 6 in groove body
Be water, and oxidation rinsing device 5 flow into groove body in be pickle.
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
Pickle is put into or flowed out groove body；Also, the precipitation being likely to occur for the concentration and reduction that adjust solution in real time
The problems such as object, is generally to maintain solution and is in flow regime.
Inventor on this basis, analyzes：How so that copper foil is contacted and detached with solution, there are two types of modes：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, you can realize, e.g., only exist
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, you can it realizes；
Only flow control valve is set on inlet tube, the flow velocity of outlet tube is constant, when needing to improve liquid level, by improving feed liquor
The flow of pipe；When needing to reduce 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 improving liquid level, due to inlet tube flow without
Method adjusts, and therefore, is promoted indeed through the flow for reducing outlet tube, and does so the cycle that can influence 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：Before let off roll 1 unreels, the groove body in oxidation rinsing device 5
It proceeds by and promotes liquid level operation, until liquid level reaches low liquid level；
When oxidation detector 4 detects the presence of aberration problem for the first time, inlet tube flow control of the controller to oxidation rinsing device 5
Valve, outlet tube flow control valve send out 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 with 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 the above situation.And above-mentioned criterion situation needed to be considered is numerous, especially
In the presence of under neighbouring aberration 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 aberration,
Liquid level time module W zeros start timing, meanwhile, liquid level sensor transmits signal to control；
If liquid level=high liquid level, controller sends out signal to inlet tube flow control valve, outlet tube flow control valve：It keeps
Liquid level；
If liquid level<High liquid level, controller send out signal to inlet tube flow control valve, outlet tube flow control valve：It improves
Liquid level is until be in high liquid level；
As liquid level time module W=preset time W1, liquid level time module W stops timing, meanwhile, controller is to inlet tube stream
Control valve, outlet tube flow control valve send out signal：Liquid level starts to reduce, until low liquid level（It is reduced to low liquid from high liquid level
Aberration problem is not detected in the period internal oxidition detector 4 of position）.
The minimum value of preset time W1 is：Copper foil autoxidation detector 4 is to the time for leaving oxidation rinsing device 5, time
According to practical condition can value be：5-20s.
The actual effect of above-mentioned Liquid level mode is：If neighbouring copper foil aberration region<Preset time W1 × copper foil
Forward speed, liquid level are constantly in high liquid level.If neighbouring copper foil aberration region>The forward speed of preset time W1 × copper foil,
Then liquid level can obtain：" promotion-reduction " operational order.
For clear water washer 6, its purpose is to by the pickle washes clean of copper foil surface.When it is designed,
Have to the cycle 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 aberration 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
Blocking roller 5-2 can be less than by changing the liquid level of washer 5.And clear water washer 6 for the first time find aberration 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, be arranged in inlet tube flow control valve
Front.It is to further increase the flow velocity of inlet tube that the pump main purposes of 5-6, which are 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 the better embodiment of the present invention, only is used for facilitating illustrating 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 put forward 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
Without departing from the technical feature content of the present invention, in the range of still falling within the technology of the present invention feature.
