[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] refer to Figures 1-4 A copper foil water absorption device includes a frame 1, a first fixing component 2 and a second fixing component 3 arranged at intervals along the horizontal direction on the frame 1;

[0042] The first fixing component 2 is detachably connected to a first water-absorbing component 23 and a second water-absorbing component 24; the second fixing component 3 is detachably connected to a third water-absorbing component 33 and a fourth water-absorbing component 34; the second water-absorbing component 24 and the third water-absorbing component 33 are respectively attached to the lower surface and the upper surface of the copper foil to absorb water from the lower surface and the upper surface of the copper foil.

[0043] The frame 1 is provided with a drive mechanism 11, which is used to drive the second water absorption component 24 and the third water absorption component 33 to separate from the copper foil, and to make the first water absorption component 23 and the fourth water absorption component 34 respectively adhere to the upper and lower surfaces of the copper foil.

[0044] It should be noted that the copper foil is under tension during the water absorption process, therefore the first water absorption component 23, the second water absorption component 24, the third water absorption component 33, and the fourth water absorption component 34 do not participate in the tensioning of the copper foil.

[0045] In this design, the lower surface of the copper foil is attached to the surface of the second water-absorbing component 24, and the upper surface of the copper foil is attached to the surface of the third water-absorbing component 33. Water is absorbed through the upper and lower surfaces of the copper foil of the second water-absorbing component 24 and the third water-absorbing component 33. When the second water-absorbing component 24 and the third water-absorbing component 33 need to be replaced, the driving mechanism 11 drives the second water-absorbing component 24 and the third water-absorbing component 33 to separate from the copper foil, and the first water-absorbing component 23 and the fourth water-absorbing component 34 attach to the upper and lower surfaces of the copper foil respectively to continue absorbing water. In this way, the worker can disassemble the second water-absorbing component 24 and the third water-absorbing component 33 for replacement.

[0046] Preferably, the first fixing component 2 includes two first mounting seats 21 disposed on the frame 1, the two first mounting seats 21 being located on the left and right sides of the copper foil conveying direction, respectively;

[0047] The first mounting base 21 is provided with a first sliding plate 22 that can slide in the vertical direction, and the two first sliding plates 22 are arranged opposite to each other. The first water absorption component 23 and the second water absorption component 24 are detachably connected between the two first sliding plates 22.

[0048] The second fixing component 3 includes two second mounting bases 31 on the frame 1, the two second mounting bases 31 being located on the left and right sides of the copper foil conveying direction, respectively;

[0049] The second mounting base 31 is provided with a second sliding plate 32 that can slide in the vertical direction, and the two second sliding plates 32 are arranged opposite to each other. The third water absorption component 33 and the fourth water absorption component 34 are detachably connected between the two second sliding plates 32.

[0050] The drive mechanism 11 is connected to the first slide plate 22 and the second slide plate 32. The drive mechanism 11 is used to drive the first slide plate 22 and the second slide plate 32 to slide towards each other so that the second water absorption component 24 and the third water absorption component 33 are separated from the copper foil, and so that the first water absorption component 23 and the fourth water absorption component 34 are respectively attached to the upper surface and the lower surface of the copper foil.

[0051] The drive mechanism 11 includes a rotary motor 111 and a first gear 113 mounted on the frame 1. The first gear 113 is located between the first slide plate 22 and the second slide plate 32 and is meshed with the first slide plate 22 and the second slide plate 32. The frame 1 is provided with a connecting seat 12 that is rotatably connected to the first gear 113.

[0052] The output end of the rotary motor 111 is provided with a connecting shaft 112, and the connecting shaft 112 is provided with a second gear 114 that corresponds one-to-one with the first gear 113. The second gear 114 meshes with the first gear 113.

[0053] The first water-absorbing component 23 is the first water-absorbing roller, the second water-absorbing component 24 is the second water-absorbing roller, the third water-absorbing component 33 is the third water-absorbing roller, and the fourth water-absorbing component 34 is the fourth water-absorbing roller.

[0054] Specifically, the sidewalls of the first slide plate 22 and the second slide plate 32 both have teeth that mesh with the first gear 113. When the second and third water-absorbing rollers need to be replaced, the rotation motor 111 drives the rotation of the second gear 114, which in turn drives the rotation of the first gear 113. The rotating first gear 113 then drives the first slide plate 22 to slide on the first mounting base 21, while the second slide plate 32 slides on the second mounting base 31. Since the first slide plate 22 and the second slide plate 32 are meshed with the first gear 113, the first slide plate 22 and the second slide plate 32 slide towards each other, thereby causing the second and third water-absorbing rollers to separate from the copper foil. The first and fourth water-absorbing rollers then adhere to the upper and lower surfaces of the copper foil, respectively, to replace the second and third water-absorbing rollers in continuing to absorb water from the upper and lower surfaces of the copper foil.

[0055] In this embodiment, it also includes a first elastic telescopic component 4 symmetrically arranged on the two first slide plates 22 and a second elastic telescopic component 5 symmetrically arranged on the two first slide plates 22; the first elastic telescopic component 4 is located above the second elastic telescopic component 5;

[0056] The first elastic telescopic component 4 includes a first fixed base 41 connected to the first slide plate 22. The first fixed base 41 is provided with a first spring (not shown in the figure). One end of the first spring is provided with a first fixing member 42. The two ends of the first water absorption component 23 respectively abut against the two first fixing members 42.

[0057] The second elastic telescopic component 5 includes a second fixed base 51 connected to the first slide plate 22. The second fixed base 51 is provided with a second spring (not shown in the figure). One end of the second spring is provided with a second fixing member 52. The two ends of the second water absorption component 24 respectively abut against the two second fixing members 52.

[0058] The upper ends of the first fixing base 41 and the first fixing member 42 are both provided with a first notch 43; the upper ends of the second fixing base 51 and the second fixing member 52 are both provided with a second notch 53.

[0059] Specifically, a first notch 43 is provided at the upper end of both the first fixed base 41 and the first fixed member 42. This makes it easier for workers to place the first water-absorbing roller. Workers insert the two ends of the first water-absorbing roller into the two fixed members through the first notch. The two ends of the first water-absorbing roller compress the two first springs respectively, and the two first springs clamp and fix the first water-absorbing roller. When it is necessary to remove the first water-absorbing roller, since the first fixed member 42 and the first fixed base 41 are both provided with the first notch 43 at their upper ends, workers can directly lift the first water-absorbing roller to remove it.

[0060] In this embodiment, a third elastic telescopic component 6 and a fourth elastic telescopic component 7 are symmetrically arranged on the two second slide plates 32; the third elastic telescopic component 6 is located above the fourth elastic telescopic component 7.

[0061] The third elastic telescopic component 6 includes a third fixed base 61 connected to the second slide plate 32. The third fixed base 61 is provided with a third spring (not shown in the figure). One end of the third spring is provided with a third fixing member 62.

[0062] The fourth elastic telescopic component 7 includes a fourth fixed seat 71 connected to the second slide plate 32. The fourth fixed seat 71 is provided with a fourth spring (not shown in the figure). One end of the fourth spring is provided with a fourth fixing member 72. The two ends of the fourth water absorption component 34 respectively abut against the two fourth fixing members 72.

[0063] The upper ends of the third fixing base 61 and the third fixing member 62 are both provided with a third notch 63; the upper ends of the fourth fixing base 71 and the fourth fixing member 72 are both provided with a fourth notch 73.

[0064] The second, third, and fourth elastic telescopic components operate in the same way as the first telescopic component, so they will not be described in detail in this embodiment.

[0065] The second gap 53, the third gap 63, and the fourth gap 73 have the same structure as the first gap 43, so they will not be described in detail in this embodiment.

[0066] Example 2

[0067] refer to Figure 5 A copper foil cleaning system includes a cleaning tank 8, a drying device 9, a winding roller 10, and a copper foil water absorption device as described in Example 1.
