Specific meanings of the above terms in the embodiments of the present invention can be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1-3, an immersion liquid winding apparatus according to an embodiment of the present invention includes an immersion liquid assembly 110, a conveying assembly 120, a first driving assembly 130, a liquid removing assembly 141, and a winding assembly. The immersion component 110 is provided with an immersion groove 111 for containing a base liquid, the conveying component 120 is used for conveying the base material 10 to be immersed in the base liquid, the first driving component 130 is used for driving the immersion component 110 and the conveying component 120 to be relatively close to or far away from each other so that the base material 10 is immersed in or far away from the base liquid, the liquid removing component 141 is provided with a base liquid for enabling the base material 10 to pass through so as to wipe the surface of the base material 10, and the winding component is used for winding the base material 10 attached with the base liquid.

According to the immersion liquid winding apparatus provided in the above embodiment, after the substrate 10 is placed on the transfer assembly 120, the first driving assembly 130 drives the transfer assembly 120 relatively close to the immersion assembly 110 so that a portion of the substrate 10 is immersed in the base liquid. After the immersion of the part of the base material 10 is completed, the transfer unit 120 operates to output the base material 10 immersed in the base liquid to the immersion liquid tank 111 and to input the part not immersed in the liquid to the immersion liquid tank 111. Then, the substrate 10 soaked with the base liquid passes through the gap in the liquid removing component 141, the liquid removing component 141 wipes the substrate 10, so that the base liquid is uniformly coated on the substrate 10, and the excess base liquid leaves the substrate 10 under the action of the liquid removing component 141. Finally, the winding unit winds the base material 10 to which the base liquid is attached.

By adopting the immersion liquid winding equipment, the immersion liquid is performed before the base material 10 is wound, compared with the immersion liquid process after winding in the prior art, no extra pressure is needed to be applied, the immersion liquid is completed in the conveying process, the time is saved, and the production efficiency is improved.

It should be added that, in the embodiment of the present invention, the substrate 10 may be a strip-shaped electrode plate, and the base liquid may be an electrolyte.

Referring to fig. 2 or fig. 3, in an embodiment of the present invention, the liquid removing assembly 141 includes two or more liquid removing members rotatably and sequentially disposed, and a space exists between two adjacent liquid removing members. The substrate 10 is contacted with the liquid removing members on both sides thereof while passing through the gap, and a part of the substrate 10 surface is attached to the liquid removing members by the mutual friction between the substrate 10 and the liquid removing members.

It should be noted that, in the present embodiment, the design of the liquid removing member rotating can reduce the friction between the substrate 10 and the liquid removing member, thereby indirectly improving the quality of the obtained product. When the liquid removing member is plural, the substrate 10 passes through the space between every two adjacent liquid removing members in turn. Thus, the base liquid is uniformly attached to the substrate 10 by the multiple actions of the liquid removing member.

In addition, the amount of the base liquid deposited on the surface of the substrate 10 can be controlled by designing the size of the gap.

Preferably, the liquid removal member is cylindrical.

In a specific embodiment, two adjacent liquid removing members are arranged in parallel. This allows the substrate 10 to be uniformly stressed, thereby improving the quality of the base liquid coating.

Referring to fig. 2 and 4, in a more specific embodiment, the liquid removing assembly 141 further includes a flow guiding member 142 for guiding the base liquid on the liquid removing member to the immersion tank 111, and the flow guiding member 142 is in gap connection with the liquid removing member. By adopting the design, the consumption of the base liquid can be reduced, and the production and manufacturing cost can be reduced.

In a more specific and special embodiment, one end of the flow guiding element 142 is provided with a positioning hole 1421 and a first adjusting hole 1422, both of which are used for installing the flow guiding element 142, so that the flow guiding element 142 can rotate around the positioning hole 1421 through the first adjusting hole 1422. The positioning hole 1421 is a circular hole, the first adjusting hole 1422 is an arc hole, and bolts are disposed in the positioning hole 1421 and the first adjusting hole 1422. During assembly, the positioning hole 1421 and the first adjusting hole 1422 are pre-assembled with bolts, the air guide 142 is rotated to adjust the position of the air guide 142, and the bolts are tightened to fix the air guide 142.

In another specific and special embodiment, the liquid removing assembly 141 further includes a sliding block 143 for mounting the flow guiding element 142 and a mounting element 144 fixedly connected to the sliding block 143, the mounting element 144 is provided with a groove 1441 adapted to the sliding block 143, and the sliding block 143 is slidably disposed in the groove 1441. A second adjusting hole 1431 opposite to the groove 1441 is formed in the sliding block 143, and the second adjusting hole 1431 is a kidney-shaped hole.

By adopting the two structures, the distance and the relative angle between the flow guide piece 142 and the liquid removing piece can be adjusted, so that a better flow guide direction can be determined according to actual conditions. Moreover, by adopting the design, the influence caused by device errors and machining errors can be eliminated. In addition, the position of the diversion member 142 can be adjusted to enable the diversion member 142 to be attached to the base material 10, so that the wiped base liquid can be prevented from splashing. .

Preferably, the flow guiding member 142 is made of sheet metal, one end of the flow guiding member 142 is bent and flanged, and the positioning hole 1421 and the first adjusting hole 1422 are located at the flanged position.

Further, the mounting member 144 is provided with a third adjusting hole corresponding to the liquid removing member, and the liquid removing member is fixed to the mounting member 144 through the third adjusting hole and the bolt. Specifically, the third regulation hole is a kidney-shaped hole. For the mounting steps, reference is made to the first adjustment hole 1422, which will not be described herein.

It should be added that, in the above embodiments, the first driving assembly 130 and the second driving assembly 160 may be of a motor structure, a cylinder structure, a hydraulic cylinder structure, or the like.

Further, in one embodiment, the transport assembly 120 includes a plurality of transport wheels 121 for abutting the substrate 10, wherein two of the transport wheels 121 are disposed opposite the immersion tank 111. When the first drive assembly 130 drives the immersion fluid assembly 110 and the transport assembly 120 relatively close, the two transport wheels 121 enter the immersion fluid tank 111. After the two conveying wheels 121 enter the immersion liquid tank 111, the conveying unit 120 may continue to convey the substrate 10, or the conveying unit 120 may convey the substrate 10 after leaving the immersion liquid tank 111.

It is understood that the transport wheel 121 may be externally powered or may rotate with the substrate 10 as the substrate 10 is stretched.

Referring to fig. 2 or 3, in another embodiment of the present invention, the immersion liquid winding apparatus further includes a cover member 150 for covering the immersion liquid tank 111 and a second driving assembly 160 for driving the cover member 150 to disengage from or cover the immersion liquid tank 111. When the immersion liquid winding device is not used, the immersion liquid groove 111 can be covered by the sealing cover part 150, so that the base liquid is prevented from being polluted by impurities, and the quality of the base liquid is ensured.

In this embodiment, the immersion component 110 is provided with a liquid inlet hole 115, a liquid outlet hole 116 and an overflow hole 112, which are communicated with the immersion tank 111, wherein the overflow hole 112 is located on the side wall of the immersion component 110. When the liquid level of the base liquid in the immersion liquid tank 111 reaches the height of the overflow hole 112, the base liquid flows out from the overflow hole 112. Through the design of the overflow hole 112, the liquid amount of the base liquid in the immersion liquid tank 111 can be ensured not to exceed a certain height, so that the base liquid is prevented from overflowing to influence the cleaning work after the conveying assembly 120 enters the immersion liquid tank 111.

In a specific embodiment, the immersion liquid winding apparatus further comprises a liquid storage tank 210, a first pipe 220, a second pipe 230, and a pump assembly 240; the liquid storage tank 210 has a receiving space for receiving the base liquid, the first pipeline 220 communicates with the receiving space and an external space, the second pipeline 230 has a first port 231 and a second port 232, the first port 231 communicates with the receiving space, the second port 232 communicates with the liquid inlet hole 115, and the pump assembly 240 is disposed between the first port 231 and the second port 232 to drive the base liquid in the receiving space to enter the immersion liquid tank 111 along the second pipeline 230. It will be appreciated that the reservoir 210 corresponds to a sealed container, and the first pipe 220 allows the air pressure in the receiving space to be kept the same as the air pressure outside, so that the base liquid can flow into the immersion liquid tank 111 along the second pipe 230 after the pump assembly 240 is operated.

It can be understood that, for the convenience of control, the first valve 221 is disposed at the first pipeline 220, and the air pressure is controlled by controlling the on/off of the first valve 221, so as to prevent the base liquid from flowing out in abnormal situations.

The immersion liquid winding device further includes a third conduit 250, the third conduit 250 having a first port 251 and a second port 252, the first port 251 communicating with the containment space, and the second port 252 communicating with the overflow aperture 112.

The second pipe 230 also has a third port 233, and the third port 233 is used for communicating with an external device, so that the liquid in the external device can enter the immersion liquid tank 111 through the second pipe 230. The third conduit 250 also has a third port 253 and a fourth port 254, the third port 253 communicating with the drain hole 116, and the fourth port 254 being used to drain fluid from the external device under the action of the pump assembly 240.

It should be noted that the external device mainly outputs the cleaning liquid for cleaning the second pipeline 230, the pump assembly 240 and the immersion liquid tank 111, the cleaning liquid may be clean water or other solvents, and the external device may also be a common tap water pipeline.

Referring to fig. 5, for the same convenience of control, the third port 233 is provided with the second valve 234, the fourth port 254 is provided with the third valve 256, and the first port 251 is provided with the second valve 234.

Referring to fig. 1 and 5, the immersion liquid winding apparatus will be described in detail through a liquid charging process, a liquid discharging process, and a cleaning process.

The liquid adding process, i.e. the liquid storage tank 210 outputs the base liquid to the immersion liquid tank 111:

the first valve 221 is opened to allow the base liquid to be discharged from the receiving space, the second valve 234 is closed to cut off the communication with the external device, the third valve 256 is closed to prevent the base liquid from flowing into the drain hole 116, and the fourth valve 255 is opened and communicates with the overflow hole 112. Under the action of the pump assembly 240, the base liquid flows along the second pipeline 230 and enters the immersion liquid tank 111 at the liquid inlet hole 115. When the base liquid is added in an excessive amount, the base liquid flows back to the accommodating space through the overflow hole 112.

Liquid discharge process, namely discharging the base liquid in the immersion liquid tank 111:

the first, second, and fourth valves 255 are closed, the third valve 256 is opened, and the base liquid in the immersion liquid tank 111 flows out directly from the drain hole 116, passes through the third pipe 250, and is discharged to the fourth port 254.

A cleaning process, in which an external device outputs a cleaning liquid to clean the immersion tank 111:

first valve 221 is closed, second valve 234 is opened, third valve 256 is opened, fourth valve 255 is closed, and second drive assembly 160 drives cover member 150 to cover immersion fluid tank 111. At this time, the third port 233, the pump unit 240, the second port 232, the liquid inlet hole 115, the immersion liquid tank 111, the liquid discharge hole 116, the third port 253, and the fourth port 254 form a passage. The pump assembly 240 operates to cause the cleaning fluid to enter the immersion fluid tank 111 along the second pipe 230, and the cleaning fluid cleans the base fluid attached to the second pipe 230 and in the immersion fluid tank 111 under the pressure provided by the pump assembly 240. The cleaning liquid then flows out through the drain hole 116, passes through the third pipe line 250, and is discharged from the fourth port 254.

It is worth mentioning that the above-mentioned cleaning process is critical for the cover member 150.

In a more specific embodiment, the immersion liquid winding device further comprises a liquid collecting member 260, the liquid collecting member 260 facing the fourth port 254 for collecting the mixture of the cleaning liquid and the base liquid discharged from the fourth port 254.

The liquid storage tank 210 is also provided with a second heating assembly 270 for heating the temperature of the base liquid and a second temperature sensor 275 for detecting the temperature of the base liquid in the liquid storage tank 210. This is done to maintain the base liquid at a suitable temperature, say 50 deg..

Referring to FIG. 6, in another embodiment of the present invention, the immersion liquid assemblies 110 are provided in a plurality and at a plurality of positions during the transport of the substrate 10. The effect of the base liquid adhering to the base material can be further improved by immersing the substrate several times.
