[0030] The first negative pressure conveyor line 1 and the second negative pressure conveyor line 2 are spliced together. The first dust removal structure 5 and the first brush mechanism 3 are set on the conveying path of the first negative pressure conveyor line 1. The working surfaces of the first dust removal structure 5 and the first brush mechanism 3 face the conveying surface of the first negative pressure conveyor line 1.

[0031] The height of the first negative pressure conveyor line 1 is lower than the height of the second negative pressure conveyor line 2.
[0032] In this embodiment, the conveying surface of the first negative pressure conveying line 1 is located on its upper surface, and the conveying surface of the second negative pressure conveying line 2 is located on its lower surface. The electrode 400 is placed on the upper surface of the first negative pressure conveying line 1 and conveyed to the second negative pressure conveying line 2.

[0035] The first negative pressure chamber and the second negative pressure chamber are hollow shell structures. The first conveyor belt 11 and the second conveyor belt 22 are laid on the corresponding hollow shells to form the first negative pressure chamber and the second negative pressure chamber. For example, the first conveyor belt 11 is laid on the hollow shell with an open upper end to form the first negative pressure chamber, and the second conveyor belt 22 is laid on the hollow shell with an open lower end to form the second negative pressure chamber.
[0036] Optionally, in this embodiment, the first dust removal structure 5 includes a first housing 511. One side of the first housing 511 is open and covers the first negative pressure conveyor line 1. The other side of the first housing 511 is provided with a plurality of first dust removal exhaust ports 521. During the transmission of the electrode 400, due to the effect of vacuum negative pressure, the electrode 400 is adsorbed on the upper surface of the first conveyor belt 11. Then, the first dust removal structure 5 adsorbs all solid particles and dust ions on the upper surface of the electrode 400, and the adsorbed solid particles and dust ions are discharged from the first dust removal exhaust ports 521. Optionally, the first dust removal exhaust ports 521 are connected to the external collection device 300 through a pipe 9.
[0037] The second dust removal structure 6 includes a second housing 612. One side of the second housing 612 is open and covers the second negative pressure conveyor line 2. The other side of the second housing 612 is provided with several second dust removal exhaust ports 622. During the transmission of the electrode 400, due to the vacuum negative pressure, the electrode 400 is adsorbed on the lower surface of the second conveyor belt 22. Then, the second dust removal structure 6 adsorbs all solid particles and dust ions on the upper surface of the electrode 400, and the adsorbed solid particles and dust ions are discharged from the second dust removal exhaust ports 622. Optionally, the second dust removal exhaust ports 622 are connected to the external collection device 300 through a pipe 9.
[0038] Optionally, in this embodiment, the first brush mechanism 3 includes a first driving member 311, a first housing 321, and a first brush 331. The first driving member 311 is drivenly connected to the first brush 331. The first brush 331 is located inside the first housing 321, and one side of the first housing 321 is open and faces the first negative pressure conveyor line 1. Optionally, the first driving member 311 can be a motor. The motor is connected to the first brush 331, and the motor drives the first brush 331 to rotate. During the rotation, the first brush 331 brushes away the small solid particles solidified on the upper surface of the electrode 400.
[0039] The second brush mechanism 4 includes a second drive member 412, a second housing (not shown in the figure), and a second brush (not shown in the figure). The second drive member 412 is drivenly connected to the second brush. The second brush is located inside the second housing, and one side of the second housing is open and faces the second negative pressure conveyor line 2. Optionally, the second drive member 412 can be a motor. The motor is connected to the second brush, and the motor drives the second brush to rotate. During the rotation, the second brush brushes away the small solid particles solidified on the upper surface of the electrode 400.
[0040] Furthermore, it also includes a frame 7, on which the first negative pressure conveyor line 1, the second negative pressure conveyor line 2, the first brush mechanism 3, the second brush mechanism 4, the first dust removal structure 5, and the second dust removal structure 6 are all mounted;
[0041] A negative pressure box 8 is installed inside the frame 7. The first negative pressure chamber, the second negative pressure chamber, the first brush mechanism 3, and the second brush mechanism 4 are all connected to the negative pressure box 8. The negative pressure box 8 is a box structure with a connection port 81. The connection port 81 is used to connect to an external device that generates negative pressure, such as a vacuum device 200. The vacuum device 200 creates negative pressure in the negative pressure box 8, thereby creating negative pressure in the first negative pressure chamber, the second negative pressure chamber, the first brush mechanism 3, and the second brush mechanism 4. Figure 2 and Figure 3 As shown, the first negative pressure chamber, the second negative pressure chamber, the first brush mechanism 3, and the second brush mechanism 4 are all connected to the negative pressure box 8 via pipes 9. The first housing 321 and the second housing are also connected to the negative pressure box 8 via pipes 9.
[0042] The first empty housing can be mounted on the frame 7, and can be part of the frame 7. The first box 511 and the second box 612 are box structures. The two ends of the first box 511 are mounted on the frame 7, and the middle of the first box 511 is suspended, leaving a gap with the conveying surface (upper surface) of the first negative pressure conveying line 1 to allow the electrode 400 to pass through. The two ends of the second box 612 are mounted on the frame 7, and the middle of the second box 612 is suspended, leaving a gap with the conveying surface (lower surface) of the second negative pressure conveying line 2 to allow the electrode 400 to pass through. The two ends of the first housing 321 are mounted on the frame 7, and the middle of the first housing 321 is suspended, leaving a gap with the conveying surface (upper surface) of the first negative pressure conveying line 1 to allow the electrode 400 to pass through. The two ends of the second housing are mounted on the frame 7, and the middle of the second housing is suspended, leaving a gap with the conveying surface (lower surface) of the second negative pressure conveying line 2 to allow the electrode 400 to pass through.
[0043] Furthermore, a guide plate 10 is provided at the starting position of the first negative pressure conveying line 1. The starting position is in terms of the conveying direction. Optionally, the guide plate 10 is mounted on a bracket 101. The guide plate 10 includes two plate-shaped members with obtuse angles. One plate-shaped member is arranged parallel to the conveying surface of the first negative pressure conveying line 1, and a gap is left between the conveying surfaces of the first negative pressure conveying line 1 to allow the electrode 400 to pass through.
[0044] Furthermore, a magnet 20 is provided at the starting position of the first negative pressure conveyor line 1. The magnet 20 is positioned behind the guide plate 10 and before the first brush mechanism 3. The magnet 20 is used to attract metal particles on the surface of the electrode 400. Here, "behind the guide plate 10" refers to the front and rear of the electrode in the electrode conveying direction.
[0045] The present invention provides that the electrode 400 automatically completes the dust removal on both sides of the electrode 400 after it flows into the first negative pressure conveyor line 1 of the equipment, and automatically conveys it out after dust removal. No manual assistance is required throughout the process, which has high work efficiency, reduces manpower, and lowers costs.
[0046] Specifically, after the electrode 400 flows into the first negative pressure conveying line 1 from the guide plate 10, it first passes through the magnet 20 to remove the metal particles on the surface of the electrode 400. Then, the valve of the first negative pressure conveying line 1 is opened, and the electrode 400 is held by the first negative pressure conveying line 1 and conveyed backward. During the conveying process, the solid particles solidified on the upper surface of the electrode 400 are brushed off by the first brush mechanism 3 and continue to be conveyed backward. When it passes through the non-contact first dust removal structure 5, all solid particles and dust ions are completely removed by the first dust removal structure 5, and the upper surface of the electrode 400 is cleaned (dust removal on the front of the electrode 400). When electrode 400 reaches the second negative pressure conveyor line 2, the valve of the second negative pressure conveyor line 2 opens, and the valve of the first negative pressure conveyor line 1 closes. Electrode 400 is completely sucked up by the second negative pressure conveyor line 2 and moves backward. When it passes through the second brush mechanism 4, the solid particles solidified on the lower surface of electrode 400 are brushed off by the second brush mechanism 4 and continue to be conveyed backward. When it passes through the non-contact second dust removal structure 6, all solid particles and dust ions are completely sucked away by the second dust removal structure 6, and the lower surface of electrode 400 is cleaned (dust removal on the reverse side of electrode 400). The second negative pressure conveyor line 2 can be connected to the customer's on-site conveyor line. When electrode 400 has completely passed through the second dust removal structure 6, the valve of the second negative pressure conveyor line 2 closes, and electrode 400 naturally falls onto the customer's on-site conveyor line to enter the next stage.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
