With this structure, when the plating liquid in the plating chamber 11 leaks out from the sliding plate 13, the liquid storage chamber 17 formed between the baffle 16 at the front end and the sliding plate 13 can also shield the plating liquid, further preventing the plating liquid from leaking out.

[0043] In one embodiment, see Figure 4 As a specific implementation of the drum-type electroplating device provided in the embodiment of the present application, a second mounting seat 18 is further provided on the frame 1, and a second mounting groove 181 for inserting the baffle 16 is provided on the second mounting seat 18, and a second sealing gasket 182 is provided in the second mounting groove 181.

The gap between the baffle 16 and the second mounting seat 18 can be filled by the second sealing gasket 182, so that leakage of the electroplating solution can be further avoided.

[0044] In one embodiment, see Figure 2 As a specific implementation of the drum-type electroplating device provided in the embodiment of the present application, the drum-type electroplating device further includes a first reflux pipe 6 connecting the liquid storage chamber 17 and the liquid storage tank 12. In this structure, the electroplating liquid in the electroplating chamber 11 and / or the liquid storage chamber 17 can be refluxed to the liquid storage tank 12 through the first reflux pipe 6, so that the electroplating liquid can be recycled.

[0045] In one embodiment, see Figure 1As a specific implementation of the drum-type electroplating device provided in the embodiment of the present application, the drum body 2 is provided with a plurality of liquid outlet holes (not shown) along a circumferential annular array, and a second nozzle 21 is installed in the drum body 2, and the second nozzle 21 is connected to the liquid pump 4. Specifically, the number of the second nozzles 21 can be multiple, and the multiple second nozzles 21 are arranged at intervals in a semicircular structure. In this structure, by arranging the second nozzle 21 inside the drum body 2, the electroplating liquid sprayed by the second nozzle 21 can flow out from the liquid outlet hole, so that the electroplating operation can be performed on the sheet 200 to be electroplated, which is attached to the inner side of the drum body 2.

[0046] Optionally, see Figure 5 When performing local electroplating, it is necessary to stick a pressing tape 100 on the sheet 200 to be plated to cover the position of the sheet 200 that does not need to be plated. For example, when it is necessary to perform local electroplating on the bottom surface of the sheet 200 to be plated, stick a pressing tape 100 on the bottom surface, and the pressing tape 100 is provided with a plating hole 101, and the plating hole 101 is aligned with the position of the sheet 200 to be plated that needs to be plated, and the position of the pressing tape 100 without a hole can cover the position of the sheet 200 to be plated that does not need to be plated. The pressing tape 100 can be stuck to the top surface of the sheet 200 to be plated that is in contact with the drum body 2, and the pressing tape 100 does not have a plating hole 101, so as to completely cover the pressing tape 100, and cooperate with the plating liquid sprayed from the first nozzle 14 to achieve local electroplating of the bottom surface of the sheet 200 to be plated. When the pressing tape 100 attached to the top surface of the sheet 200 to be plated has a plating hole 101, the bottom and top surfaces of the sheet 200 to be plated can be partially plated in cooperation with the plating liquid ejected from the second nozzle 21. When the pressing tape 100 attached to the bottom surface of the sheet 200 to be plated does not have a plating hole 101, and only the pressing tape 100 attached to the top surface of the sheet 200 to be plated has a plating hole 101, the top surface of the sheet 200 to be plated can be partially plated.
