Description
Technical field
The utility model relates to the aftertreatment production technology of electrolytic copper foil, relates in particular to a kind of preheated tank that slows down Copper Foil warpage.
Background technology
In electrolytic copper foil production process, Copper Foil is produced by cathode roller, after hot-air seasoning, under certain tension force, is tightly wrapped on wind-up roll.Due to the acting in conjunction of the factors such as temperature, tension force, easily cause the warping phenomenon of Copper Foil, when Copper Foil cuts into sheet, the perk of limit portion, makes the production of follow-up work copper coated foil plate have quality problems.It is poor that bow warping is exactly said sheet material planeness, with the circuit card of this board materials production, when crossing wave soldering streamline, or cannot get through, or occur top rake phenomenon, damages circuit card, causes huge financial loss.Meanwhile, some circuit cards are after hot air leveling, when warpage is more serious, particularly complete machine producer does not need circuit card to be screwed in electrical equipment, but while adopting plug-in mounting, heavier warpage just can cause dress assembling production and the strength problem of electrical equipment that do not gone up or filled not firm, serious impact.
Utility model content
The purpose of this utility model is to provide a kind of preheated tank that slows down Copper Foil warpage, can slow down the warpage issues after Copper Foil is produced, and for follow-up work provides effective assurance, improves the quality of production and efficiency, the waste reducing production costs.
The technical solution adopted in the utility model is:
Slow down a preheated tank for Copper Foil warpage, comprise the heating container and the electric control box that are provided with case lid, heating container is provided with import waste heat pipeline and outlet waste heat pipeline, is provided with a plurality of electric heating panels in heating container, and heating container inner side-wall is provided with support; Described electric control box comprises master control switch, switch is carried out in contactless coil and temperature control and master control switch series is unified into loop, contacts of contactor one end connects the first power switch, the contacts of contactor the other end connects electric heating panel, the signal output part that switch connects temperature controller is carried out in temperature control, temperature controller connects second source switch, and the input terminus of temperature controller connects temperature sensor.
Described temperature sensor is located at heating container inside.
Described electric heating panel is evenly laid in heating container bottom surface.
Described support includes multilayer, is secured by bolts on heating container inner side-wall.
Described import waste heat pipeline is provided with manual valve.
The utility model is sent into heating container inside by the waste heat of the treatment and finishing section baking oven of electrolytic copper foil by import waste heat pipeline, the temperature signal gathering according to temperature sensor again, by electric control box, according to the temperature value of setting, the temperature in heating container is controlled automatically, to realize the thermostatically heating to Copper Foil, reach the object that slows down warpage, for follow-up work provides effective assurance, improve the quality of production and efficiency, the waste reducing production costs simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electric control box schematic block circuit diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises heating container 1 and the electric control box 3 that is provided with case lid 2, heating container 1 is provided with import waste heat pipeline 4 and outlet waste heat pipeline 5, import waste heat pipeline 4 is provided with manual valve 6, in heating container 1, be provided with a plurality of electric heating panels 7, electric heating panel 7 is on average laid in heating container 1 bottom surface, and heating container inner side-wall has been bolted multilayer bracket 8; Described electric control box 3 comprises master control K switch 1, contactless coil S and temperature control are carried out switch 12 and are connected into loop with master control K switch 1, contacts of contactor K4 one end connects the first power switch K2, the contacts of contactor K4 the other end connects electric heating panel 7, the signal output part that switch 12 connects temperature controller 10 is carried out in temperature control, temperature controller 10 connects second source K switch 3, and the input terminus of temperature controller 10 connects temperature sensor 11, and temperature sensor 11 is located at heating container 1 inside.
The utility model in use, is first opened the manual valve 6 that import waste heat pipeline 4 is provided with, and the waste heat gas of the treatment and finishing section baking oven of electrolytic copper foil is sent in heating container 1, passes into a large amount of warm airs in heating container 1, and after thermodiffusion, heating container 1 temperature rises.Then open successively master control K switch 1, the first power switch K2 and the second source K switch 3 of electric control box 3, manually set and need temperature value.Temperature sensor 11 is passed to temperature controller 10 by the temperature signal of heating container 1 inside, and temperature controller 10 by analysis, controls by output terminal adhesive and the disconnection that temperature controller is carried out switch 12.Temperature when heating container 1 inside has reached design temperature, and temperature controller is carried out switch 12 in off-state, and electric heating panel 7 is not worked, but the waste heat gas of the treatment and finishing section baking oven of general electrolytic copper foil can not reach the temperature value needing; So temperature controller 10 output terminals are controlled the adhesive that temperature controller is carried out switch 12, after adhesive, contactless coil S is charged, probe of contactor K4 adhesive, electric heating panel 7 line conductions, electric heating panel 7 is started working, and heating container 1 is started to heating, after temperature reaches, preparation work is complete.
Now, open the case lid 2 of heating container 1, need to carry out the pre-warmed Copper Foil 9 of warpage and neatly be placed on support 8, can place 8-10 roller, then heating container case lid 2 is covered tightly, put into the Copper Foil 9 that needs heating.After arriving heat-up time, take out the Copper Foil 9 of handling well, add new Copper Foil 9.In this process, the waste heat gas heating of the treatment and finishing section baking oven of electrolytic copper foil and electric control box 3 automatic control heating operations always, temperature keeps thermostatically heating always.So far Copper Foil 9 is put in circulation, not only the waste heat gas of the treatment and finishing section baking oven of electrolytic copper foil is repeated to recycling, can effectively slow down again the problem of the warpage of Copper Foil 9.
