[0035] Embodiment

[0036] Please refer to Figs. 1-2 The horizontal electroplating cathode conductive roller cleaning device shown in the figure comprises a cathode conductive roller 1 and a water containing device 2, the water containing device 2 is provided with a U-shaped groove, and the cathode conductive roller 1 is rotatably connected in the U-shaped groove. The cathode conductive roller 1 matches the U-shaped groove. In this embodiment, the length of the water containing device 2 is 1 meter, and the U-shaped groove of the water containing device 2 can contain liquid. Among them, the cathode conductive roller 1 is not entirely immersed in the water containing device 2. In this embodiment, the cathode conductive roller 1 is installed at the bottom of the water containing device 2, and since there is less liquid at the bottom of the water containing device 2, only when the cathode conductive roller 1 rotates, the surface of the cathode conductive roller 1 can be wetted, so as not to cause crystallization on the surface of the cathode conductive roller 1.

[0037] The horizontal electroplating cathode conductive roller cleaning device further comprises a spraying device 3, and the spraying device 3 is arranged above the cathode conductive roller 1. Among them, the spraying device 3 can only spray water in the non-production state or before production. When continuously producing, water is not sprayed to the cathode conductive roller 1. The spraying device 3 comprises a spraying pipe 4, and a plurality of liquid outlets are arranged on the spraying pipe 4. The spraying device 3 further comprises a liquid inlet, and the liquid inlet is detachably connected with the spraying pipe 4. In this embodiment, the spraying pipe 4 is made of PFA material, which has excellent chemical stability, electrical insulation and temperature stability.

[0038] The horizontal electroplating cathode conductive roller cleaning device further comprises a battery piece 5 arranged between the spraying device 3 and the cathode conductive roller 1. The battery piece 5 can move in the horizontal direction to carry out electroplating.

[0039] The horizontal electroplating cathode conductive roller cleaning device further comprises an electroplating tank 6 arranged on one side of the water containing device 2. The electroplating tank 6 contains electroplating liquid (chemical liquid). In the embodiment, the water containing device 2 and the electroplating tank 6 are fixed by screws. In the embodiment, the water containing device 2 is made of PPN material, which has high chemical stability, acid and alkali corrosion resistance, and excellent mechanical properties and aging resistance. In addition, the electroplating tank 6 and the water containing device 2 are made of the same material. The water containing device 2 is provided with a plating liquid backflow port 7 connected with the electroplating tank 6.

[0040] The horizontal electroplating cathode conductive roller cleaning device further comprises a servo motor and a PLC control system. The servo motor is connected with the cathode conductive roller 1. The servo motor can drive the cathode conductive roller 1 to rotate. In order to align the surface of the cathode conductive roller 1 for washing mode, the servo motor is used to accurately control the rotation of the cathode conductive roller 1 to realize efficient cleaning of the cathode conductive roller 1. The PLC control system is electrically connected with the spraying device 3. The battery piece 5 is electrically connected with the spraying device 3 through the PLC control system.

[0041] After the horizontal electroplating cathode conductive roller cleaning device is started, the battery piece 5 moves in the horizontal direction to carry out metal deposition production. Before production, due to the intermittent production time, there is a possibility of chemical liquid crystallization on the surface of the cathode conductive roller 1. In order to ensure the effect of metal deposition of the battery piece 5, the spraying device 3 will wash the cathode conductive roller 1 before the battery piece 5 moves, and then production will be carried out to ensure the effect and quality of the electroplating layer. Specifically, when the PLC control system detects that the battery piece 5 enters, the signal will be fed back to the PLC control system, and the PLC control system will feed back to the execution control of the spraying device 3 to clean and spray the cathode conductive roller 1. The spraying device 3 will automatically wash the cathode conductive roller 1, and the spraying will last for 30 seconds. After completion, the battery piece 5 enters production to ensure the effect and quality of the electroplating layer.

[0042] In addition, the spraying device 3 above the cathode conductive roller 1 flushes the cathode conductive roller 1, and the liquid of the water containing device 2 is gradually filled. Since the cathode conductive roller 1 is driven by the servo motor, the cathode conductive roller 1 rotates and contacts the liquid surface of the water containing device 2 below, thereby achieving the self-cleaning function. The flushed crystal and liquid are caught by the water containing device 2. The liquid caught by the water containing device 2 is used to wet the cathode conductive roller 1 once every rotation of the cathode conductive roller 1, so that the cathode conductive roller 1 is not crystallized again.

[0043] After the liquid of the water containing device 2 is filled, the liquid returns to the electroplating tank 6 through the plating solution reflux port 7, so that the cleaned liquid can be continuously used (since the liquid on the cathode conductive roller 1 after cleaning and the plating solution in the electroplating tank 6 are the same, no other impurities or pollution is generated).

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
