[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-4A copper powder cleaning device for electrolytic copper foil includes a first fixed frame 1, a conveying roller unit 2 for transporting copper foil, and a first cleaning unit 3 for cleaning copper powder. The conveying roller unit 2 is connected to the first fixed frame 1, and the first cleaning unit 3 is connected to the first fixed frame 1. The first cleaning unit 3 is provided with a detachable powder removal chamber 31 for collecting the copper powder cleaned by the first cleaning unit 3. The powder removal chamber 31 is provided with a powder removal channel 32 for copper powder to pass through, and the powder removal chamber 31 is also provided with an adjustment unit 33 for opening or closing the powder removal channel 32.

[0028] In practical applications, copper foil is conveyed by conveying roller unit 2 and copper powder on the copper foil is cleaned by first cleaning unit 3. Specifically, when copper foil with copper powder passes through first cleaning unit 3, the operator opens the powder removal channel 32 by adjusting unit 33, so that copper powder can enter the powder removal chamber 31. When the powder removal chamber 31 needs to be replaced, the operator closes the powder removal channel 32 so that the copper powder can remain in the powder removal chamber 31, thereby recycling the copper powder, improving the utilization rate of copper powder and facilitating the operation of the operator.

[0029] Preferably, the first cleaning unit 3 includes a second fixed frame 34, a brush roller 35 rotatably connected to the second fixed frame 34, and an air extraction unit 36 ​​for absorbing copper powder. The second fixed frame 34 is connected to the first fixed frame 1, the air extraction unit 36 ​​is connected to the top inside the second fixed frame 34, and the powder removal chamber 31 is slidably connected to the second fixed frame 34 and located above the brush roller 35.

[0030] In the above design, when the copper foil passes through the second fixing frame 34, the brush roller 35 will brush away the copper powder on the copper foil. Some copper powder will remain on the brush roller 35, and the copper powder on the brush roller 35 will be drawn into the de-powdering chamber 31 by the air extraction unit 36. In particular, when it is necessary to disassemble the de-powdering chamber 31, the operator needs to first close the de-powdering channel 32 through the adjustment unit 33, and then close the air extraction unit 36. After the replacement is completed, the air extraction unit 36 ​​and the de-powdering channel 32 can be opened to complete the replacement of the de-powdering chamber 31. It should be noted that the brush roller 35 is driven by a drive motor, which is not shown in the figure.

[0031] Preferably, the dust removal chamber 31 is provided with a filter plate 311 for preventing copper powder from entering the air extraction unit 36, and the filter plate 311 is located at the top of the dust removal chamber 31.

[0032] Through the above design, the filter plate 311 can prevent copper powder from entering the suction unit 36, thereby preventing the suction unit 36 ​​from malfunctioning. In other words, the filter plate 311 can better protect the suction unit 36 ​​and improve its service life. On the other hand, the filter plate 311 can also prevent copper powder from floating out of the dust removal chamber 31 when the dust removal chamber 31 is replaced.

[0033] Preferably, the bottom of the dust removal chamber 31 is provided with a fixing plate 341, the fixing plate 341 is provided with a through groove 3411, the through groove 3411 forms the dust removal channel 32, the adjusting unit 33 is a connecting plate 331, the fixing plate 341 is provided with a groove 3412, and the connecting plate 331 is slidably connected in the groove 3412.

[0034] When the connecting plate 331 is located within the through groove 3411 and covers the entire through groove 3411, the dust removal channel 32 is in a closed state; when the connecting plate 331 is not located within the through groove 3411, the dust removal channel 32 is in an open state.

[0035] In this embodiment, the operator can adjust the position of the connecting plate 331 through the adjusting unit 33 to determine whether the connecting plate 331 is located within the through groove 3411, thereby controlling the opening and closing state of the dust removal channel 32. Specifically, the operator can control the connecting plate 331 to slide within the groove 3412. When dust removal is required, the dust removal channel 32 can be opened. When the dust removal chamber 31 needs to be replaced, the dust removal channel 32 can be closed first, and the dust suction operation can be stopped for a period of time before replacement. In this way, it can be ensured that when the dust removal chamber 31 is replaced, copper powder will not float out of the dust removal chamber 31, and copper powder will not fall out of the through groove 3411 due to gravity, thereby improving the copper powder recovery rate.

[0036] Preferably, the width of the powder removal channel 32 matches the width of the brush roller 35.

[0037] In this embodiment, the width of the de-powdering channel 32 matches the width of the brush roller 35. However, in reality, the width of the de-powdering channel 32 can be greater than the width of the brush roller 35, thereby ensuring that copper powder can be drawn into the de-powdering chamber 31 by the air extraction unit 36, thus improving the efficiency of copper powder removal.

[0038] Preferably, one end of the connecting plate 331 is provided with a handle 332 for opening or closing the dust removal channel 32.

[0039] The above design allows staff to easily operate the handle 332 to adjust the position of the connecting plate 331, which is the opening and closing state of the powder removal channel 32.

[0040] Preferably, one end of the de-powder chamber 31 is provided with a first locking block 312, and the other end is provided with a second locking block 313 that matches the first locking block 312.

[0041] In the above design, when the staff replaces the dust removal chamber 31, they can easily disassemble it by connecting the first locking block 312 with the second locking block 313 of the other dust removal chamber 31 and then pushing it. This facilitates alignment and improves replacement efficiency.

[0042] Preferably, the system further includes a second cleaning unit 4, which includes two dust-adhesive belt modules 41. A gap 42 is provided between the dust-adhesive belt modules 41 to allow copper foil to pass through. The dust-adhesive belt modules 41 are used to pick up copper powder from the copper foil. The dust-adhesive belt modules 41 are located on one side of the first cleaning unit 3 along the conveying direction.

[0043] In this embodiment, the dust-adhesive belt module 41 can clean up the copper powder that was not completely cleaned by the first cleaning unit 3. Specifically, when some copper powder that is difficult to clean passes through the brush roller 35, it will loosen and then be picked up by the dust-adhesive belt module 41, thereby improving the cleaning efficiency of copper powder.

[0044] Preferably, the dust-adhesive tape module 41 includes two rotating shafts 411 and a dust-adhesive tape 412; the dust-adhesive tape 412 is wound around the two rotating shafts 411; both ends of the rotating shafts 411 are rotatably connected to the first fixing frame 1.

[0045] Preferably, the second cleaning unit 4 is provided with an adjusting rod 413 for adjusting the gap 42, and the adjusting rod 413 is connected to the top of the dust tape module 41 located above.

[0046] Through the above design, the rotating shaft 411 will drive the dust-removing belt 412 to rotate. It should be noted that the rotating shaft 411 is driven by a drive motor, which is not shown in the figure. This allows the dust-removing belt 412 to continuously change the part in contact with the copper foil, thereby improving the copper powder removal effect of the dust-removing belt 412.

[0047] Specifically, the adjusting rod 413 can be found in Chinese patent (CN221694418U), and will not be described in detail here.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
